Embodiment Construction

[0032] A YTO horizontal axis wind power generating set includes a nacelle, a wind wheel mechanism, a rotating mechanism and a control mechanism.

[0033] The wind wheel mechanism includes three wind wheel blades 1 and a hub 31; the wind wheel blades 1 are connected to the wheel hub 31 through the pitch changing device 2, and the wind wheel blades 1 can be wound around by the action of the pitch changing device 2 under the action of wind force. The hub 31 is rotated in a circle to find the optimum angle of attack. At the same time, in the storm state, the pitch changing device 2 changes the pitch, so that the wind rotor blades 1 face the wind vertically, and the windward area reaches the minimum. The rotation of the hub 31 is transmitted to the lower rotation mechanism.

[0034]The rotating mechanism includes a main shaft 3 , a gear box 5 , an air compressor 10 , an air motor 25 and a generator 28 . The main shaft 3 is fixed on the nacelle through the bearing body 4, and the ...

Abstract

The invention relates to a universal horizontal-shaft wind generating unit. The front end and the rear end of a main shaft are respectively and fixedly connected with a hub and a gearbox, an output shaft of the gearbox is connected with an air compressor through a mechanical brake device and a coupler, a compression air outlet of the air compressor is connected with an air inlet of a front air storage tank at the bottom end of a tower frame through a gas pipe, the air outlet of the front air storage tank passes through a filter, a cooler and an oil-water separator and is connected with an inlet of a rear air storage tank, an outlet of the rear air storage tank is connected with an input of a pneumatic motor, an output shaft of the pneumatic motor is connected with an accelerator, an output shaft of the gas pipe is connected with a generator, and the output of the generator is directly connected with a power grid. The invention has low manufacture cost, saves a higher-price transducer,has stable generating frequency, can be directly connected with the power grid so as to achieve great economic benefits, market prospects and convenient market popularization.

Description

technical field [0001] The present invention relates to a wind power generator, which is different from the wind power generators on the market. One is that the structure of the existing wind power generation equipment is changed, and the cost of the equipment is reduced; into the national grid. The air compressor is used to drive the motor, and the motor is connected to the generator to generate electricity. Yuantong horizontal axis wind turbine. Background technique [0002] Energy is the material basis for the existence and development of human society. Over the past 200 years, the energy system based on fossil fuels such as coal, oil, and natural gas has greatly promoted the development of human society. However, while people's material life and spiritual life are constantly improving, they are also increasingly aware of the serious consequences of large-scale use of fossil fuels. Resources are increasingly depleted and the environment is deteriorating. Therefore, hum...
