[0003] The traditional way of pumping water is to use electric energy or the energy generated by fuel combustion as the power energy of the pumping device to drive the pumping device to achieve pumping. In this process, a lot of traditional energy will be wasted.

Moreover, in many remote places, it is difficult to supply electric energy, and it is difficult to transport traditional fuel oil. It is obviously unrealistic to use the traditional method to pump water. Therefore, if the potential energy of water can be used to realize water pumping, it will have broad prospects

At present, there is a type of pumping system that uses water flow to generate electricity, and then uses electric power to drive the water pump to pump water. This method can be realized for large rivers or water flows with obvious drops, but for water flows with gentle water flow and small water flow drops, this type of system Due to the low power generation efficiency, it is difficult to achieve the expected power generation purpose

Another type of pumping system directly uses the water flow to drive the pump to pump water, which is also difficult to overcome the shortcomings of being powerless in the face of a gentle water flow and a small water drop.

At present, although some pumping systems use the speed change mechanism to increase the speed obtained by the energy harvesting mechanism from the gentle water flow to drive the water pump to pump water, or use the water hammer pump to secondarily pressurize the water flow, etc., the use of micro-head fluid pumping is realized. functions, but such systems still have disadvantages such as low pumping efficiency

[0004] The patent application No. 201310649113 .X published on March 5, 2014 discloses an energy storage micro-head fluid energy pumping system. This system not only overcomes the shortcomings of traditional pumping systems that require electricity or fuel as a power source, It solves the problem of difficulty in pumping water in special areas, and also overcomes the shortcomings of traditional water pumps that use water to pump water that are difficult to use micro-heads as a power source, and because it uses an air storage cylinder as an energy storage power source, it greatly improves its working efficiency. It solves the shortcomings of the traditional micro-head pumping system, such as slow water pumping and poor instantaneous power, but because only the micro-head drives the air pump to inflate the air storage pump to store energy, and then the gas in the air storage pump drives the water hammer pump to pump water. When the water flow is high It is difficult to exert good efficiency when the volume of the air storage pump is small and the volume is limited
