Abstract

An energy storage type miniature water head fluid energy pumping system is composed of a fluid energy collecting mechanism, a speed change mechanism, a crank link mechanism, a plunger type air pump, an air storage cylinder, an air pressure motor, a rotor type water pump, a water hammer pump and a pipeline, wherein the fluid energy collecting mechanism is connected with the speed change mechanism, the speed change mechanism is connected with the plunger type air pump through the crank link mechanism, an air pump air outlet pipe of the plunger type air pump is connected with the air storage cylinder, an air cylinder air outlet pipe of the air storage cylinder is connected with the air pressure motor, the air pressure motor is connected with the rotor type water pump, and a water pump water outlet of the rotor type water pump is connected with the water hammer pump. By means of the energy storage type miniature water head fluid energy pumping system, not only is the defect that electric power or fuel needs to serve as a power source of a traditional pumping system overcome, but also the defect that a miniature water head can hardly serve as a power source for a traditional water pumping machine capable of pumping water through water energy is overcome. In addition, due to the fact that the air storage cylinder is used as an energy storage power source, working efficiency is greatly improved, and the defects that a traditional system capable of pumping water through the miniature water head is slow in water pumping, poor in instantaneous power and the like are overcome.

[0002] 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
