Description
Technical field
The utility model belongs to technical field of wind power generation, is specifically related to a kind of hydraulic pressure wind power generator.
Background technique
At present, in technical field of wind power generation, use synchronous generator in a large number.The use synchronous generator has the following disadvantages:
1) because synchronous generator from great, makes the wind generator tower barrel structure huge.
2) because the wind field fluctuation is big, the synchronous generator voltage functuation is big.
When 3) wind-force is big, adopt the mode of adjusting blade to avoid the synchronous generator g-load, influence generating efficiency.
4) synchronous generator does not have energy storage device, can't accomplish (such as accomplishing the energy storage at night, the generating on daytime) synchronously of wind-force and peak of power consumption.
5) synchronous generator does not have energy storage device, can't accomplish the strange land generating yet.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic pressure wind power generator.
The hydraulic pressure wind power generator that the utility model proposes, form by fan blade, tower tube, retarder, plunger pump, repairing fuel tank, oil pipe, high pressure accumulator, low pressure accumulator, voltage stabilizing pumping plant, oil hydraulic motor, generator, wherein: retarder is positioned on the tower tube, one end of retarder connects plunger pump, and the other end connects fan blade; Voltage stabilizing pumping plant, oil hydraulic motor and generator rest on the ground, and the voltage stabilizing pumping plant connects oil hydraulic motor, and oil hydraulic motor connects generator; Plunger pump connects repairing fuel tank, high pressure accumulator by oil pipe respectively, and high pressure accumulator connects the filler opening of voltage stabilizing pumping plant, and the repairing fuel tank connects low pressure accumulator by oil pipe, and low pressure accumulator connects the oil outlet of voltage stabilizing pumping plant.
In the utility model, the oil pipe that is connected with plunger pump can pass in the middle of the tower tube, and oil pipe is fixed on the inwall of tower tube.
Principle of the present utility model is as follows: collect wind energy by fan blade, retarder, plunger pump, and convert the hydraulic pressure energy to, be stored in the accumulator.According to the generating needs, again hydraulic pressure can be become electric energy by voltage stabilizing pumping plant, oil hydraulic motor and generator, thereby realize the conversion of wind energy to electric energy.
Working procedure of the present utility model is as follows: wind drives the fan blade rotation, and after being slowed down by retarder, drive plunger pump, plunger pump are exported high pressure oil from the oil suction of repairing fuel tank, and send into high pressure accumulator by oil pipe.Under the control of voltage stabilizing pumping plant, drive the oil hydraulic motor rotation, and drive generator for electricity generation.The effect of low pressure accumulator is oil hydraulic motor oil outlet hydraulic oil is delivered in the repairing fuel tank again.
