Abstract

The utility model discloses a downwind power generation system, comprising a bracket, which is provided with a rotary disk on the top. The rotary disk is correspondingly provided with a long supporting arm and a short supporting arm and a speed-increasing gear with double input axis. One wind wheel is arranged on the end of the long supporting arm and the other wind wheel is also arranged on the end of the short supporting arm. The rotation directions of the two wind wheels are opposite and the two wind wheels are connected with a first input axis and a second input axis of the speed-increasing gear through a drive axle thereof. The input axis of the speed-increasing gear are connected with an input axis of a constant voltage change axial pump and a hydraulic oil output tube of the constant voltage change axial pump is connected with an oil inlet of a hydraulic fluid motor. An output axis of the hydraulic fluid motor is connected with a generator. An oil outlet of the hydraulic fluid motor is communicated with a fuel-oil tank through tubes. Furthermore, an oil inlet of the constant voltage change axial pump is communicated with the fuel-oil tank through tubes. The two wind wheels of the utility model are able to follow the wind direction automatically, having the advantages of a maximum front face area and stable generator electrification performance.

Description

Electricity generating device with the wind

Technical field

The utility model relates to a kind of electricity generating device, especially relates to a kind of wind generating unit.

Background technique

Along with the high speed development of industrial and agricultural production and the raising day by day of living standards of the people, the demand of electric power is increased sharply, disparities between supply and demand are very outstanding.Present China generation mode is mainly based on thermal power generation and water generating, but coal resources are limited, and can not regenerate, and also can cause certain pollution to environment; And available water resource also is limited, and investment is big.Wind-force is inexhaustible cheap clear energy sources, utilize the device of wind-power electricity generation of a great variety, picture tower-type wind generating device, its generator is fixed on the platform of pylon top, alternator shaft links to each other with wind wheel, wind wheel blade links to each other with the directed wind wing, so that wind wheel aligns wind direction, thereby makes generator for electricity generation.The electricity generating device of this structure can not be adjusted automatically with the wind-force size, needs to adjust wind direction by the directed wind wing stability of not only complicated operation, and influence generating.

Summary of the invention

The purpose of this utility model provides a kind ofly can follow wind direction, the stable electricity generating device with the wind of power generation performance automatically.

For achieving the above object, the utility model comprises support, the top of support is equipped with rotary disk, be fixed with draw money on credit bearing arm and short supporting arm on the rotary disk opposed to each other, its structural feature is that the booster engine with dual input shaft is installed on rotary disk, end at the bearing arm of drawing money on credit is equipped with wind wheel, end at short supporting arm is equipped with wind wheel, two wind wheel direction of rotation, and first input shaft by its transmission shaft and booster engine respectively, second input shaft connects, the output shaft of booster engine links to each other with the input shaft of constant-pressure variable axial pump, the high pressure oil output tube of constant-pressure variable axial pump is connected to the filler opening of oil hydraulic motor, hydraulic motor output shaft is connected on the generator, the oil outlet of oil hydraulic motor is communicated with fuel tank by pipeline, and the filler opening of constant-pressure variable axial pump is communicated with fuel tank by pipeline.

Be provided with safety valve on the high pressure oil output tube between constant-pressure variable axial pump and the oil hydraulic motor, safety valve is provided with the return line that is communicated with fuel tank.

After adopting said structure, bearing arm and short supporting arm are fixedly mounted on the rotary disk owing to draw money on credit, and rotary disk can freely rotate relative to support, the bearing arm of drawing money on credit tends to along wind direction with short supporting arm, therefore make the wind wheel that is installed on draw money on credit bearing arm and the short supporting arm align wind direction, wind-exposuring area maximum, two wind wheel direction of rotation, can make rotary disk stressed evenly, anemotaxis can be more stable; After booster engine quickens, produce stable high pressure oil output by the constant-pressure variable axial pump, and oil hydraulic motor has stable rotating speed output, guarantees that generator can steadily generate electricity in certain wind speed excursion from the power of wind wheel.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
