The output device (10c) can be visual, audio, graphical, pictographic and other outputs like readable data, info graphic data, a pictorial data as desired by the user (60) or combinations thereof.

[12] The rigid support (20) is defined at the operative top (05a) of the elongated structure (05)and supports the adjacently disposed first drive assembly (30) and the second drive assembly (40).In one embodiment, the rigid support (20) can be the integral operative top (05a) of the elongated structure (05). In another embodiment, the rigid support (20) is externally supported (typically, from a wall or other surrounding structures) above the elongated structure by a scaffolding (21). The rigid support (20) also supports supporters (20a) like rope-rollers [vertically mounted (20ai) and/or horizontally mounted (20aii)] that facilitate rolling and guiding of the first rope (33) and the second rope (43). The size of the rigid support (20) can be varied depending on the size of the elongated structure (05) such that the rigid support (20) is to be more in size then the elongated structure (05) so that the radioactive source unit (34) and the detector unit (44) capture the elongated wall (05b) of the elongated structure (05). The material of the rigid support (20) can be any material that has adequate strength to support the first drive assembly (30) and the second drive assembly (40) and supporters (20a). For example, the material of the rigid support (20) can be a metal or polymeric or other rigid material or combination of materials.

[13] Thefirst drive assembly (30) is fitted (fastened or welded) on the rigid support (20). The first drive assembly (30) includes a first bi-directional stepper motor (31), a first winch (32) with a first spooling unit (32a), a first rope (33), a radioactive source unit (34) for radiating shielded and collimated radioactive rays (R), a level gauge (35) and a first computing controller (36). The first bi-directional stepper motor (31) rotates bi-directionally such that the rotation in clockwise direction enables winding and the rotation in anti-clockwise direction enables unwinding. The first winch (32) is bi-directionally rotatable by the first bi-directional stepper motor (31). Typically, in a non-limiting embodiment, a belt drive (32i) transmits power from the first bi-directional stepper motor (31) to the first winch (32).The first winch (32) is defined with a first spooling unit (32a). The first spooling unit (32a) mainly includes a lead screw (32ai), a shaft (32aii) and a carriage (32aiii). The lead screw (32ai) is powered by the first bi-directional stepper motor (31). Typically, in a non-limiting embodiment, the power is transmitted from the first bi-directional stepper motor (31) to the lead screw (32ai) by use of another belt drive (32aiv). The first spooling unit (32a) prevents the first rope (33) from getting snagged when spooled. The first spooling unit (32a) enables multi-layer rope winding on the winch (32). The first rope (33) further passes through roller guides (31av).

[14] The first rope (33) is woundable (when movement of the first bi-directional stepper motor (31) is in clockwise direction) and unwoundable(when movement of the first bi-directional stepper motor (31) is in counter-clockwise direction) on the first winch (32) upon the direction of the rotation of the first winch (32). The first rope (33) is allowed to be released to travel the elongated length (L) of the elongated structure (05) to allow to-and-fro movement of the radioactive source unit (34) over the elongated length (L). The radioactive source unit (34) is connected with the first rope (33) and is defined with a radioactive source (34a) (in form of discs) that radiates shielded and collimated radioactive rays (R).The radioactive source unit (34) is defined with the level gauge (35).The level gauge (35) can be assembled and disassembled with the radioactive source unit (34) or can be integral with the radioactive source unit (34). The first computing controller (36) determines travel of the first rope (33) by typically by understanding winded or unwinding of happening by the rotation of the winch (32). The first computing controller (36) adjusts the level of the first rope (33) by signaling operation (start and stop) of the first bi-directional stepper motor (31) upon instruction received from the computational processor (10b) of the computing unit (10).In a non-limiting embodiment, the first computing controller (36) is in wireless communication with the computational processor (10b).

[15] The second drive assembly (40) is fitted (fastened or welded) on the rigid support (20) and adjacent to the first drive assembly (30). The second drive assembly (40) includes a second bi-directional stepper motor (41), a second winch (42) with a second spooling unit (42a), a second rope (43),a detector unit (44) a radioactive rays shielded detector (44a), a power source (44b) and an embedded system (44c) and a level gauge (45). The second bi-directional stepper motor (41) rotates bi-directionally such that the rotation in counter-clockwise direction enables winding and the rotation in clockwise direction enables unwinding. The second winch (42) is bi-directionally rotatable by the second bi-directional stepper motor (41). Typically, in a non-limiting embodiment, a belt drive (42i) transmits power from the second bi-directional stepper motor (41) to the second winch (42). The second winch (42) is defined with a second spooling unit (42a). The second spooling unit (42a) mainly includes a lead screw (42ai), a shaft (42aii) and a carriage (42aiii). The lead screw (42ai) is powered by the the bi-directional stepper motor (41). Typically, in a non-limiting embodiment, the power is transmitted from the second bi-directional stepper motor (41) to the lead screw (42ai) by use of another belt drive (42aiv). The second spooling unit (42a) prevents the second rope (43) from getting snagged when spooled. The second spooling unit (42a) enables multi-layer rope winding on the winch (42). The second rope (33) further passes through roller guides (41av).

[16] The second rope (43) is woundable (when movement of the second bi-directional stepper motor (41) is in counter-clockwise direction) and unwoundable (when movement of the second bi-directional stepper motor (41) is in clockwise direction) on the second winch (42) upon the direction of the rotation of the second winch (42). The second rope (43) is allowed to be released to travel the elongated length (L) of the elongated structure (05) to allow to-and-fro movement of the detector unit (44) over the elongated length (L). The detector unit (44) is connected with the second rope (43) and is defined with a radioactive rays shielded detector (44a), a power source (44b) and an embedded system (44c).The radioactive rays shielded detector (44a) detects radiated collimated radioactive rays (R) emitted by said radioactive source unit (34) after passing through the elongated walls (05b) of the elongated structure (05). The power source (44b) is disposed within the detector unit (44) and powers the radioactive rays shielded detector (44a) and the embedded system (44c). The embedded system (44c) or the controller computes count rate in count per second and wirelessly communicates count per second to the computational processor (10b) of the computing unit (10).The detector unit (44) is defined with the level gauge (45).The embedded system (44c) determines travel of the second rope (43) and adjusts level of the second rope (43) by signaling operation (start and stop) of the second bi-directional stepper motor (41). In a non-limiting embodiment, the embedded system (44c) is a controller and is in wireless communicationwith the computational processor (10b). Typically, an antenna (44d) can be provided for wireless communication.

[17] Initially, the first rope (33) and the second rope (43) are unwinded and level gauges (35, 45) are observed and in unlevel condition the user (50) through the input device (10a) instructs leveling of the first rope (33) and the second rope (43).Upon input of leveling from the user (50), the computational processor (10b) communicates with the first computing controller (36) and the embedded system (44c) and instructs to level the first rope (43) and the second rope (43). When the first rope (33) and the second rope (43) are leveled, the user input through the input device (10a) initiating cracks determination and thereby the computation processor (10b) signals the first computing controller (36) and the embedded system (44c) to respectively actuate the first bi-directional stepper motor (31) and the second bi-directional stepper motor (41) at fed speed and stop travel at fed travelled distances by the user (50) through the input device (10a). At each stop (of the first bi-directional stepper motor (41) and the second bi-directional stepper motor (51)) collimated radioactive rays are detected by the radioactive rays shielded detector (44a) and the embedded system (44c) communicates count per second to corresponding to the travelled distances to the computation processor (10b) that computes to provide an output visible on the output device (10c).

[18] The present disclosure also discloses the method (200) for determining cracks of the elongated structure (05), in accordance with one embodiment of the present disclosure. The best method (200), as disclosed in the flowchart of Figure 13, requires providing (210) of a crack determination system (100) as disclosed in paragraphs [010-018] and not repeated herein to avoid repetition.

[19] The next step is installing (220). One-time installation of the rigid support (20) is performed at the operative top (05a) of the elongated structure (05) with the first drive assembly (30) and the second drive assembly (40) with the first drive assembly (30) and the second drive assembly (40).

[20] The next step is releasing (230) the first rope (33) and the second rope (43) to travel the elongated length (L). Moreover, the first rope (33) and the second rope (43) are unwounded from the respective first winch (32) and the second winch (42) and passed through respective roller guides (31av, 41av) and supporters (20a) and further released towards the elongated length (L).In non-operative configuration, the first rope (33) and the second rope (43) are left hanging from the supporters (20a). Upon releasing ofthe first rope (33) and the second rope (43), the radioactive source unit (34) and the detector unit (44) connected to respective first rope (33) and the second rope (43) are released or if not attached can be attached.

[21] The next step is observing (240) the levels of the first rope (33) and the second rope (43) by level gauges (35, 45). More specifically, the user (50) observes the level gauges (35, 45) and notes the gauged data. Though, the present method is disclosed by observing the gauged data manually by the user (50), however, the observing of the level can be by provision of sensors (like level sensors) or by use of imaging units (for capturing images or videos).

[22] The next step is communicating (250) in which the user (50) enters the gauged data into the input device (10a) and based on the input received, the computational processor (10b) processes the gauged data and determines the length of the movement (upward or downward) of the first rope (33) and/or the second rope (43) accordinglyinstructs the first computing controller (36) the actuation (includes ON and OFF, direction of rotation: clockwise or counterclockwise and number of rotation of the first winch (32) which is determined based on the real-time length) of the first drive assembly (30) and/or instructs the embedded system (44c) the actuation (includes ON and OFF, direction of rotation: clockwise or counterclockwise and number of rotation of the second winch (42) which is determined based on the real-time length) of the second drive assembly (40) such that the first rope (33) and/or the second rope (43) gets wounded or unwounded (as per real-time requirement) to achieve in-line configuration of the radioactive source (34a) and the radioactive rays shielded detector (44a). Though, the present method describes manual communication through the input device (10a), however, the sensors (if used) or imaging unit (if used) can be directly connected (either wired or wireless) to the computing processor (10b).

[23] Once, the radioactive source (34a) and the radioactive rays shielded detector (44a)are leveled and in-line, the next step is inputting (260) by the user (50) initiation of cracks detection through the input device (10a).Upon inputting (260), the computation processor (10b) signals the first computing controller (36) and the embedded system (44c) to respectively actuate the first bi-directional stepper motor (31) and the second bi-directional stepper motor (41) at fed speed and stop (as defined in the computation processor (10b)) travel at fed travelled distances by the user (50) through the input device (10a) accessed by the computation processor (10b). At each stop collimated radioactive rays (R) are detected by the radioactive rays shielded detector (44a) and the embedded system (44c) communicates count per second to corresponding to the travelled distances to the computation processor (10b) that computes to provide an output visible on the output device (10c). The output can be readable data, an info graphic data and a pictorial data. Though the present disclosure discloses manual input for cracks determination actuation, however, after leveling, the computation processor (10b)can be fed with automatic actuation for cracks detection at predefined time interval.

[24] The present crack determination system (100) and method (200) for determining cracks for an elongated structure as described in the present disclosure does not require manual inspection of cracks by moving inside the elongated structure or stopping/interrupting the function of the elongated structure as required conventionally. Thus, the crack determination system (100) and method (200) for determining cracks for an elongated structure facilitates preventive inspection and prevents undesired stoppage or undesired accidents.

[25] The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments,steps or alternatives may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
