DESC:FIELD OF THE INVENTION
The present invention relates to the field of siphon systems. More particularly, the present invention relates to a siphon system for conveying liquid in a curvature from a first vessel to a second vessel.
BACKGROUND OF THE INVENTION
A siphon is used to deliver liquid, typically water, from a first vessel to a second vessel arranged at lower level as compare to the first vessel. The siphon conveys the liquid over the edge of the first vessel and delivers it into the second vessel. A conventional siphon has two legs connected via an inverted U-shaped bend. The siphon conveys liquid from the first vessel to the second vessel. However, to convey the liquid, the second vessel needs to be arranged at a lower level than the first vessel. The conventional siphon cannot convey liquid from the first vessel into the second vessel if the second vessel is at higher level that the first vessel. Such a conventional siphon is shown in figure 1.
The siphon (100) according to the prior art has two legs (110, 120) connected via an inverted U-shaped bend (130). The siphon (100) conveys liquid from a first vessel (140) to a second vessel (150). However, in said conventional design, the second vessel (150) needs to be arranged at a lower level than the first vessel (140) to convey the liquid. The siphon (100) known in the art has structural limitations to convey liquid from the first vessel into the second vessel if the second vessel is at higher level that the first vessel.
Therefore, there is felt a need of a siphon system that alleviates the aforementioned drawbacks of conventional siphon systems.
SUMMARY OF THE INVENTION
According to an aspect of the invention, a siphon system is designed for conveying liquid in a curvature from a first vessel to a second vessel, the system comprises a siphon having an integral profile formed of a plurality of legs and bends, wherein each bend is arranged between two consecutive legs, such that a first leg is in liquid communication with the first vessel, and a last leg delivers liquid to the second vessel. If the siphon is extended horizontally by a channel away from an intermediate bend below and along an imaginary horizontal tangent line drawn on the surface of first vessel, and if an outlet of the last leg is below the imaginary horizontal tangent line, the siphon conveys liquid from the first vessel to the second vessel arranged at higher level than the first vessel.

The present invention discloses a siphon system which can convey liquid from a first vessel into a second vessel even if the second vessel is placed at higher level than the first level without consumption of electricity or other fuel energy source.
Figure 2 illustrates a schematic view of a siphon system for conveying liquid in a curvature from a first vessel (210) to a second vessel (220), according to an embodiment of the present invention. The siphon system (200), comprises a siphon (230) having an integral profile formed of a plurality of legs and bends, wherein each bend is arranged between two consecutive legs, such that a first leg (250) is in fluid communication with the first vessel (210), and a last leg delivers liquid to the second vessel (220).
The syphon (230) comprises a first inverted U-shaped bend (270) of which one end of the bend (270) is in fluid communication with the first leg (250) and the other end of the bend (270) is connected to a second leg (280). The intermediate bend (290) is connected to the second leg (280) at one end, and a channel (390) at the other end, wherein said channel (390) is coupled with a third leg (300). A second inverted U-shaped bend (310) is connected to the third leg (300) at one end and the other end is connected with a fourth leg.
The siphon system (200) of the present invention further comprises an impeller (260), a non return valve (330), and an air pressure tank (340) connected to the first leg (250) below the water level of the first vessel (210). The impeller (260) immersed in the first vessel (210) arranged at the end of the first leg (250), said impeller (260) is configured to be rotated by an upward flow of water. The non return valve (330) is provided at the inlet mouth of the first leg (250) before the impeller. The air pressure tank (340) with a hydraulic pressure line provided adjacently outside of the first leg (250), the pressure tank (340) is connected above the impeller such that half portion of the pressure tank (340) is filled with liquid.
The siphon system (200) further comprises a vacuum indicator (360) and an air removing control valve (370) mounted at the top of first inverted U-shaped bend (270). The siphon system (200) also includes a control valve (320) connected at end of the second inverted U-shaped bend (310), said control valve (320) selectively allows outflow of liquid from the siphon to the second vessel (220).
When the siphon (230) is extended horizontally by the channel (390) away from an intermediate bend (290), below and along an imaginary horizontal tangent line (400) drawn on the surface of first vessel, and an outlet of the last leg is below the imaginary horizontal tangent line (400), the siphon (230) conveys liquid from the first vessel (210) to the second vessel (220) wherein second vessel (220) is arranged at higher level than the first vessel (210). That is, if, the height of the first vessel (210) is the lowest level, in case the siphon (230) is extended hori-zontally far away from the intermediate bend (290) the height of the second water storage i.e. the second vessel (220) can be further increased.
When liquid, for example water is passing through the channel (390) placed horizontally and parallel below the imaginary tangent line (400), there is no any action of gravitational force and effect of air pressure. Thus, water can pass through the channel (390) horizontally for so many kilometres without undergoing projectile effect.
When the length of this horizontal tangent channel (390) is progressing ahead the rate of change of curvature also increase. Through this way the height of the second water storage i.e. the second vessel (220) can be further increased.
The rate of change of curvature (h) can be calculated by an equation which is derived based on radius of surface (R) and the imaginary tangent line (400), the equation satisfies:
h = v(R2 + T2)
The rate of change of curvature (h) can also be calculated by an equation which is derived based on radius of surface (R) and the hypotenuse of right angled triangle (H) (shown in figure 3), the equation satisfies:
h = H-R
The siphon system of the present invention works on the curvature of the earth surface. It is considered, the ocean is one continuous body of water, it’s surface tends to seek the same curved level throughout the word. The curvature also varies from river mouth to hill valley.
Accordingly, in an embodiment of the present invention, location of first water vessel (210) is considered as the fresh river water in river mouth area near sea shore. Location of second water vessel (220) is considered as water reservoir or dam locat¬ed on the hill top, situated far away from river mouth area at sea shore. The total height of the first leg (250) having 12 meters height with upward flow of water column with maximum 10.33 meters heights only. A non return valve (330) provided at the inlet mouth of the first leg (250). Above the non return valve an impeller (260) is provided inside the pipe of the first leg (250). An air pressure tank (340) provided adjacently outside of the first leg (250), wherein the air pressure tank is mounted above the impeller such that half portion of the tank is filled with water. This water level is same as the water level of the first vessel (210). Additional air pressure is acting on the water level in the tank as a hydraulic pressure. If the air pressure is directly applied in the first leg (250), air bubbles may create inside the water column and that can break the upward flow of water.
The first leg (250) including the non return valve (330), the impeller (260), and the additional hydraulic pressure line (340) with air pressure tank is immersed minimum one meter below the water level of the first vessel. Height of the first leg (250) is considered be maximum 10 meters water column from first vessel’s water level up to the first inverter U-Shaped bend (270). One meter vertical pipe is provided at the top of the first inverter U-shaped bend (270). This one meter pipe is filled with water up to 0.33 meter and remaining height of pipe 0.67 meters is vacuum. A vacuum indicator (360) and air removing control valve (370) is fitted at the top of the pipe.
Thus, the total height of the syphon system is 12 meters from the starting point. Total height of water column is 10.33 meters (380) (it is same as the height of water barometer). Of 12meters, one meter is immersed in water, 10 meter is water column (250) up to first inverted U-shaped bend (270), one meter vertical pipe from top of inverted U-shaped bend (270) which has 0.33 meters water and 0.67 meters vacuum (350).
The height of second leg (280) (downward flow of water) is maximum 10.5 meter from inverted U shaped bend (270), the intermediate bend (290) has to be immersed in water at least by 0.5 meter (only below the water level).
By extending the horizontally channel (390) far away from the intermediate bend (290), the height of the second water storage i.e. the second vessel (220) can be further increased. Therefore, intermediate bend (290) is a L- shaped bend, from this L-shaped bend a longest channel (390) is provided to connect hill top located at far distance. This channel (390) can be imagined as a tangent of earth’s curvature from river mouth at sea shore to hill top reservoir. The L-shaped bend (290) is also immersed in water, which is considered as the starting point of the tangent.
Third leg (300) conveys water to the hill top reservoir through second inverter U-shaped bend (310) via flow control value (320). The outlet end must be located below the tangent line of earth (400). The maximum height of water level in the reservoir or dam can come up to equal to the line of tangent (400). Flow control value (320) provided near the outlet end of the pipe line.
According to the present invention, if the ocean is one continuous body of water its surface tends to seek the same curved level throughout the world. This curvature is also effecting lengthwise from river mouth to hill valley.
Figure 3 shows calculation of rate of change of curvature of earth, according to one embodiment of the present invention. Referring to figure 3
h = Rate of change of curvature of Earth
R = Radius of the earth = 6378 km
T = Tangent of earth = 113 km (It can increase or decrease as per distance of hill top location)
H = Hypotenuse of right angled triangle which is shown in figure 3.
H = v(63782 + 1132) = 6379.000940 km
h = 6379.000940 - 6378 = 1.0009 km
h= 1 km
If the distance from river mouth to hill top reservoir is 113 km, the height of the hill top is one km above the mean sea level.
By the above stated equations, the further increments of height of water level in the reservoir on hill top can be calculated. Table 1 provides the rate of change of curvature of the earth between curvature of the earth and imaginary tangent line.
Table 1: rate of change of curvature of the earth

Depending up on the rate of change of curvature of the earth and imaginary tangent of the earth, a siphon system can be installed from river mouth area at the sea shore to hill top reservoir for utilization of more quantity of river water for the society.
