Wind-power pumping water generating system

Abstract

A wind pumping generating system contains high reservoir (1), low reservoir (2), fan (3), water pump (4, 6), water turbine (5, 7) and hydraulic generator (8). The fan rotates under the wind action to drive (4) pump water from (2). The water flows into (5) through pipe to drive it rotating. The effluent water from (5) will flow into the (1). Rotation of (5) drives (6) working, which pumps water in (2) into (1) through pipe. Water from (1) washes (7) and drives it rotating. Water from (7) will flow into (2). Rotation of (7) drives (8) rotating for generating electricity. The invention has high wind usage, small investment, low cost and output electric energy with high quality.

Description

technical field [0001] The invention relates to the field of wind power utilization, in particular to wind power water extraction and hydropower generation. Background technique [0002] The utilization of wind energy mainly adopts the mode of generating electricity by wind power generator at present, and also has a small amount of ways of raising water by wind power for irrigation and drinking water. [0003] Wind turbine power generation is the wind energy driving the rotation of the fan, which drives the generator to generate electricity. Due to the great uncertainty of the wind energy, the running speed of the wind turbine is very unstable, and the voltage, waveform, and frequency of the electric energy generated by the generator are difficult to meet the requirements of grid connection. It is usually rectified by a rectifier circuit, and can only be input into the grid after meeting the requirements of grid connection. The device for rectifying the electric energy out...

Problems solved by technology

[0007] In Example 1 of patent 01135136.5 "Feng Shui Combined Power Generation Method and Device", the wind energy is firstly converted into electrical energy through the wind generator, and then the electric energy is used to drive the electric water pump to pump water. In this process, complex rectification equipment is still required to convert the output of the wind generator The electric energy is converted into the electric energy required by the electric water pump, the input cost is high, and the power quality is poor

In Embodiment 2, one wind wheel is equipped with one waterwheel or water lifter, which is suitable for small-scale wind-shui power station projects, and the utilization efficiency of large-scale wind turbines is low

[0008] Patent 200610026128.0 "A Method of Wind-Hydraulic Combined Power Generation" describes that water is lifted from a low place to a high place through wind-powered water lifting equipment. For large-scale wind turbines, the distance from the ground is tens of meters or even hundreds of meters, which will lose the power of the wind turbine and The potential energy of the high water surface difference will greatly reduce the conversion efficiency of wind energy
