Embodiment Construction
[0012] The present invention will be further described below in conjunction with accompanying drawing.
[0013] Such as Figure 1 to Figure 3 As shown, a wind generator includes a blade 1, a main shaft 3, a stator 5 and a rotor 6, and also includes a sleeve 9 and a cooling box 10. The blade shafts where several blades 1 are located are connected to the main shaft 3 through a coupling 2, The sleeve 9 is set on the end of the main shaft 3 away from the blade 1 and is fixedly connected with the main shaft 3. A cavity 15 is formed between the sleeve 9 and the main shaft 3, and a coolant is placed in the cavity 15; the sleeve 9 The end away from the blade 1 communicates with the cooling box 10, and the end of the cooling box 10 away from the blade 1 is evenly distributed with cooling fins 11; the rotor 12 is set outside the sleeve 9 and fixedly connected with the sleeve 9, the rotor 12 The rotor excitation winding 8 is arranged on it; the stator 5 is arranged on the periphery of t...

The invention discloses a wind power generator. The wind power generator comprises blades, a main shaft, a stator, a rotor, a sleeve and a cooling box, wherein a blade shaft is connected with the main shaft via a coupling, the sleeve sleeves one end, far away from the blades, of the main shaft, a cavity is formed between the sleeve and the main shaft, a cooling liquid is placed in the cavity, one end, far away from the blades, of the sleeve communicates with the cooling box distributed with cooling fins, the rotor sleeves the sleeve, the stator is arranged at the periphery of the rotor and is connected with the main shaft and the sleeve via connection parts, each connection part comprises a stator side plate, a connection rod, a roller and an annular rail, a plurality of stator side plates are arranged in a radial direction and at equal angles by taking an axis of the main shaft as a center, the stator side plates are fixedly connected with the stator, one end, far away from the main shaft, of the connection rod is fixedly connected with the stator side plate, the roller is arranged at one end, near to the main shaft, of the connection rod, and the annular rail is arranged on the main shaft or the sleeve and is matched with a groove of the roller. The wind power generator can be used for cooling the power generator, the structure of the wind power generator is also suitable for heat dissipation, and the service lifetime of the wind power generator can be prolonged.
Description
technical field [0001] The invention relates to a generator, in particular to a wind power generator, and belongs to the technical field of wind power generation equipment. Background technique [0002] Wind energy, as a clean, pollution-free renewable energy, has attracted more and more attention from all over the world. Its reserves are huge, and the global wind energy is about 2.74×10 9 MW, of which the available wind energy is 2×10 7 MW is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. Wind power converts the kinetic energy of the wind into electrical energy. Using wind power to generate electricity is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries pay more attention to wind power generation. In the western region of my country, wind power generation technology has been widely used. A wind turbine is a device that converts wind energy into electrica...
