Air-pressure pumping-out long-distance water transmission system and potential energy generating system

Abstract

The invention discloses an air-pressure pumping-out long-distance water transmission system and a potential energy generating system. The air-pressure pumping-out long-distance water transmission system comprises a high-position water tower which is close to a water source, a water lifting device and a power supply device for supplying energy to the water lifting device; the water lifting device is used for lifting water in the water source to the high-position water tower; and the water source flows to a user side from the high-position water tower. With the adoption of the air-pressure pumping-out long-distance water transmission system provided by the invention, the water is lifted up by the low-level water source at a low air pressure in a high potential energy manner, so that the water source can be transmitted in a long distance.

Description

technical field [0001] The invention relates to the field of hydraulic transportation and power generation, in particular to a pneumatic pumping remote water delivery system and a potential energy power generation system. Background technique [0002] At present, water conservancy irrigation generally uses water pumps to transport water sources to farmland, but due to the limitation of the electric power of the pumps, long-distance transport cannot be realized; Transporting by truck or pumping is not only a waste of energy, it is also inefficient. [0003] In addition, most of the existing urban high-level water towers use electric energy to lift water to the high-level water towers, which consumes a lot of energy. [0004] Chinese patent document CN 2240058Y discloses an energy storage device, including: a lever mechanism for raising the potential energy of quantitative water storage; energy transmission part; a low power consumption electric part for pulling the transmis...

Problems solved by technology

[0006] (1) The above-mentioned patent realizes the improvement of the water storage potential energy through the principle of leverage, which belongs to intermittent water lifting, and the amount of water lifted each time is limited to a certain extent, the efficiency of water lifting is low, and it takes a long time to reach a certain amount of power generation the water lifting process;

[0007] (2) Due to the use of the principle of leverage to lift water, the height of the water is also limited to a certain extent, and it is impossible to lift the water to a higher place. Therefore, the potential energy of the water after water lifting is small. According to the law of energy, This will inevitably affect the powe
