BOREWELL, OPENWELL, CREE AND CANAL PUMPING USING MECHANICAL PRINCIPLES

FIELD OF THE INVENTION

The present invention relates to borewell, openwell, creek and canal pumping. Particularly, present invention relates to a water pumping device without consuming either electricity or any fuel. This invention uses the principles of nano technology and mechanics to pump fluid from borewell, openwell, cree and canals, stream, lake or ponds.

BACKGROUND OF THE INVENTION

Several pumping systems involving different pumping and extraction devices have been developed for transfer of fluids from an open well/pond. These pumping systems run on AC motor and require electricity for operation and the electricity consumption increases as the depth of suction increases. Patent No. 2,134,465 relates to a deep well pump such as a pump suitable for pumping oil from bored wells or for pumping water or water with minerals in solution from considerable depths below the surface of the earth. The invention uses compressed air as the motive force for pumping the oil or other liquid and in which the pump assembly is located at the desired depth in the well for receiving the oil or other liquid, which liquid is positively elevated by a plunger pump, the .plunger being operated by an air engine having a cylinder and a piston. produced when the volume of the chamber is reduced by the hydraulic pressure, and a weight attached to the container for sinking the container and vessel deep under water.

Patent No. 5,186,611 relates to a pump arrangement for pumping liquid by compressed air. When the pump chamber is empty and the valve is open, the compressed air from the blower is vented to the ambient environment. Liquid is forced through the inlet pipe and into the pump chamber due to the pressure head. As the pressure head at the bottom of the inlet pipe is greater than the pressure head produced by the blower of the pump arrangement, the supplied compressed air will force the liquid out of the pump chamber and out through the discharge pipe. In this fashion, the pump exhausts fluid. Patent No. 5,507,601 relates to a method of transferring water provides potential energy with the air pressure of compressed air and uses compressed air used for transfer repeatedly and continuously. The compressed air is retained at the place where the water is transferred from. The compressed air retained is drawn and compressed by a compressor for another transfer operation, and the water is transferred continuously by an alternate replacement between the compressed air and the water. The water can be brought into a place by water pressure where the compressed air acts on the water.

In case of centrifugal pumps, the efficiency tends to decline as flow rates rise after peak efficiency is reached. The pump efficiencies also tend to decline over time to wear. In case of plunger pumps, lot of energy is wasted when the fluid is accelerated in the piping system, hence decreases efficiency of any plunger pump system. The present invention makes the design simple with nano materials and makes corrosion free. The efficiency remains high throughout the pump lifecycle as the nano material is very less prone to wear out. The pumping system requires a very little/no power because of mechanical advantage principle involved in it.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Fig. 1 describes linear guide way and bearing mechanism for lifting water according to the present invention. A sturdy container 9 is connected with linear bearings 10 which move up and down on linear guides 11. This sturdy container 9 is connected by either rope pulley mechanism 13 or a screw rod 14. These mechanisms are run by the compressed air engine 1. Whole system is placed on support beams 12. The sturdy container 9 is filled with water when dipped in reservoir 6. When it is slided till overhead tank 2, a solenoid valve 8 opens and transfers water into over head tank 2. Water from the tank 2 then flows with some velocity through pipe on turbines 3 forcing it to rotate which could be used for power generation. Water coming out of turbine 3 can either be sent for utilization 4 or sent back to same lake 5.
