Specification

DESC:FIELD OF INVENTION:
[001] The present invention relates to the three point measuring device. More specifically, the present invention relates to the device for measuring the frame space or surface distortion between two consecutive frames of the pressure hull of the submarine.

BACKGROUND AND PRIOR ART:
[002] The structure of the pressure hull is supported by the ring-shaped stiffening frames. The ring-stiffened hulls have better structural performances and are widely used in underwater vehicles and submarines. The ring-shaped stiffening frame consists of the T-shaped section that is usually located inside the pressure hull.

[003] The T-Shaped stiffening members are welded to the inner wall of the pressure hull of the submarine. The space between two consecutive frames, which separates them from one another by a predetermined distance, is referred to as the frame space. The surface distortion is caused by the welding process at the frame space. Even after taking all necessary precautions, welding distortions cannot be fully eliminated.

[004] There are a few different methods that have been used in the past to measure the frame space between the frames of a submarine's pressure hull such as visual inspection or ultrasonic testing method. The visual Inspection method involves physically inspecting the frame space using a measuring tool such as a ruler or caliper. It is a simple method, but it can be time-consuming and may not be suitable for measuring frame spaces in hard-to-reach areas. This method required taking four different readings and then their average has to be calculated. After putting the scale horizontally along the hull surface, the distorted places can be seen as gaps between the two mating surfaces. The same is measured by putting a feeler gauge as a measuring tool of different thicknesses. The ultrasonic testing method uses high-frequency sound waves to measure the distance between the frames. It is a non-destructive method that can provide accurate measurements, but it can be expensive and requires specialized equipment.

[005] Hence, there is a need for a measuring device to resolve the above-mentioned problem and facilitate a more precise measurement of the frame space distortion.

OBJECTS OF THE INVENTION:

[006] The principal object of the present invention is to provide a measuring device for measuring the frame space distortion between two consecutive frames of the pressure hull of the submarine.

[007] Another object of the present invention is to provide a measuring device for the measurement of the gap between any two long surfaces and any distorted plates.

[008] Another object of the present invention is to provide a measuring device that takes less time to measure pressure hull distortion over the frame space as the distortion can be measured directly by taking a single reading.

[009] Another object of the present invention is to achieve variable accuracy by using the vernier caliper with various least count.

[010] Yet another object of the present invention is to provide a measuring device that can be modified as per the requirement during the measurement.

SUMMARY OF THE INVENTION:
[011] Accordingly, the present invention provides a three point measuring device, wherein the measuring device includes the vernier caliper attached to the supporting pipe through the tightening clamp. The circular clamps are connected to the supporting pipe. A measuring device measures the distortion of the surface at three points, which consist of two circular clamps and a depth measuring tip of a vernier caliper.

[012] In an aspect of the present invention, the three point measuring device 10 for measuring the space distortion comprising a vernier caliper equipped with a measuring scale and a depth measuring tip, the said vernier caliper is configured to provide precise length and depth measurements,a supporting pipe connected to the vernier caliper through a tightening clamp, a first circular clamp and a second circular clamp are affixed to the supporting pipe at equal distances from the vernier caliper.

[013] In an aspect of the present invention, the three point measuring device is configured to measure space distortion at three points defined by the first circular clamp, the second circular clamp and the depth measuring tip.

[014] In an aspect of the present invention, the first circular clamp and the second circular clamp are attached to the supporting pipe and serve as fixed reference points for surface distortion measurement.
