Technical Field

The present invention relates to the technical field of wind power generation, and in particular to a wind power generation device which is convenient for heat dissipation.

Background Art

As one of the most mature renewable energy sources, wind power generation has been widely used around the world. Traditional wind power generation devices usually consist of wind rotors, generators, towers and control systems. During the power generation process, the wind rotors rotate under the force of the wind, and the generator converts mechanical energy into electrical energy. However, due to the large amount of heat generated by long-term operation, traditional wind power generation devices have certain problems in heat dissipation.

The heat dissipation of traditional wind turbines is mainly achieved by the surface area of the wind wheel and the circulation of wind.

The present invention provides the following embodiments

Example 1

As shown in FIG1 , an embodiment of the present invention provides a wind power generation device that is easy to dissipate heat, including: a nacelle 1, a power generation device 2, a heat dissipation mechanism and a water cooling device 3.

The rotating mechanism 1 includes: a rotating motor 2 71, a gear 3 72, and a gear 4 73; the rotating motor 2 71 is fixedly installed on the top outer wall of the vertical ventilation duct 7, the output shaft of the rotating motor 2 71 is fixedly connected to the gear 3 72, the vertical section at the bottom of the wind collecting curved pipe 10 is fixedly connected to the gear 4 73, the gear 3 72 is meshed with the gear 4 73, and the rotating motor is electrically connected to the control box 41.

A control box 41 is fixedly provided at the rear of the vertical ventilation duct 7 . The control box 41 is fixedly installed on the top of the cabin 1 . The control box 41 is electrically connected to the wind direction sensor 11 and the circulation motor 27 , respectively.

The working principle of the above technical solution is as follows: when a wind power generation device that is easy to dissipate heat is working, the wind blows to the surface of the rotating blades 6, and the rotating blades 6 drive the hub 5 and the main shaft to rotate synchronously. The main shaft transmits the rotational force to the generator set 4, and the generator set 4 converts mechanical energy into micro-electric energy through the principle of magnetoelectricity. The heat dissipation mechanism mainly uses the wind flowing through the rotating blades 6 at a high altitude of the wind turbine generator to collect the wind that flows to the surface of the wind turbine generator set 4.

When the rotating mechanism 1 is working, the control box 41 receives the information from the wind direction sensor 11, and the control box 41 controls the rotating motor 2 71 to drive the gear 3 72 to rotate.

Finally, the heat is taken out of the cabin 1 through the air outlet and the second filter 13. At the same time, the water cooling device 3 also performs water cooling to dissipate heat and cool down.

The beneficial effects of the above technical solution are: by tracking the natural wind, reasonably guiding the natural wind heat dissipation and the water cooling device 3 to combine the two heat dissipation methods to dissipate heat together, the heat dissipation capacity is improved, the utilization rate of natural resources is improved, energy is saved, and it is beneficial to avoid the possibility of overheating of equipment such as wind wheels and generators, resulting in damage to the equipment and even possible fire. The device of the present invention can improve the heat dissipation efficiency of the equipment and ensure the safety and stability of the equipment.

The present invention solves the technical problem that the heat dissipation of traditional wind power generation devices is mainly achieved by the surface area of the wind wheel and the circulation of wind.
