Energy accumulation type waterpower water-raising and irrigation device

Abstract

The invention relates to an energy accumulation type waterpower water-raising and irrigation device. The device can convert water flow energy of a river in a bottomed land into air pressure energy and release the air pressure energy to an air pressure water raiser at a constant pressure after energy accumulation; and the air pressure water raiser raises water to directly drive water-saving irrigation systems of drop irrigation, spray irrigation and the like. Compared with a non-energy accumulation type waterpower water-raising device, the energy accumulation type waterpower water-raising and irrigation device has large water supply flow and constant pressure, so the water-saving irrigation systems of drop irrigation, spray irrigation and the like, which have a specific requirement on the water supply flow and the pressure, can be directly driven, and the troubles of building of an impounding reservoir and secondary pressurization can be avoided; damming buildings are not needed to be constructed on a river channel, and the basic function of the river channel such as flood discharge and the like cannot be affected; and the energy accumulation type waterpower water-raising and irrigation device has high automation degree and is low in the threshold of mass production of irrigation equipment factories and unmanned, and a plurality of universal members are adopted.

Description

Technical field: [0001] The invention relates to the field of water energy utilization, in particular to an energy storage type hydraulic water pumping irrigation device. Background technique: [0002] Water energy utilization refers to the production technology of developing and utilizing the energy contained in water bodies. Water bodies in natural rivers or oceans have three mechanical energies: potential energy, pressure energy and kinetic energy. Water energy utilization mainly refers to the utilization of the potential energy in the water body. To develop and utilize the potential energy of water, the potential energy must first be brought together in one place to form a concentrated water level difference. For example, build a dam on the river to raise the water level, or build a gentle diversion channel to form a large drop between the original river, or use a natural waterfall. Then, the water energy is converted into electrical energy through simple mechanical w...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned water energy utilization method must have the natural water drop or the topographical conditions that can form an artificial water drop through artificial buildings, so it is difficult to apply to rivers in plain areas

The practical devices for water utilization of rivers in the plains that we can see are still ancient waterwheels, which cannot be used to directly drive water-saving irrigation systems such as drip irrigation and sprinkler irrigation that have specific requirements for water supply flow and pressure.
