[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 A heat dissipation structure of a wind turbine generator comprises a shell 1 and a generator body 3, a support rod 9 is fixedly arranged on the inner side of the shell 1, a conical air duct 10 is fixedly arranged on the upper end of the support rod 9, an exhaust port 11 connected to the generator body 3 is fixedly arranged on the outer side of the conical air duct 10, and a rotating shaft 4 is rotatably arranged on the inner side of the shell 1, the rotating shaft 4 movably penetrates the conical air duct 10 and extends to the inner side, and a heat dissipation fan 5 is fixedly arranged on the outer side of the outer side of the rotating shaft 4 located at the inner side of the conical air duct 10, a driving motor 8 is fixedly arranged on the outer side of the shell 1, and the power end of the driving motor 8 movably penetrates the shell 1 and is fixedly connected to the rotating shaft 4, a plurality of groups of air inlets 12 are penetrated on the outer side of the shell 1, and a plurality of groups of air outlets 13 are penetrated on the lower side of the shell 1, when the heat dissipation fan 5 rotates in the conical air duct 10, the wind speed of the wind blown out of the exhaust port 11 is accelerated by the principle of increasing the wind speed when the air duct becomes smaller, thereby accelerating the heat dissipation and cooling effect on the generator body 3, and accelerating the air circulation speed inside the shell 1, thereby improving the heat dissipation and cooling effect.

[0022] Among them, a bracket 2 is fixedly arranged on the inner side of the outer shell 1, and the generator set body 3 is fixedly installed on the upper side of the bracket 2. The bracket 2 lifts the generator set body 3 to prevent the generator set body 3 from contacting the inner wall of the outer shell 1, thereby causing the problem of poor heat dissipation effect.

[0023] Among them, a turntable 6 is fixedly sleeved on the outside of the rotating shaft 4, and multiple groups of cleaning brushes 7 connected to the air inlet 12 are fixedly arranged on the outside of the turntable 6. When the rotating shaft 4 rotates, it drives the multiple groups of cleaning brushes 7 to clean the air inlet 12, thereby preventing impurities or foreign matter from clogging the air inlet 12 and ensuring the air intake effect of the shell 1.

[0024] Among them, a protective cover 14 is fixedly arranged on the outside of the shell 1, and the drive motor 8 is fixedly installed on the inside of the protective cover 14, and a plurality of heat dissipation holes are opened through the lower side of the protective cover 14. By setting the protective cover 14, the drive motor 8 can be protected and the service life of the drive motor 8 can be improved.

[0025] Among them, a feed opening 15 is opened through the lower side of the shell 1, and a collection box 16 docking with the feed opening 15 is arranged on the outer side of the shell 1. After the impurities or foreign matter are cleaned by the cleaning brush 7, they fall into the collection box 16 through the feed opening 15, which is convenient for collecting the impurities or foreign matter.

[0026] Among them, a mounting plate 17 is fixedly provided on the outside of the collection box 16, and a plurality of groups of mounting screws 18 are threadedly penetrated on the outside of the mounting plate 17. A plurality of mounting holes 19 for docking the mounting screws 18 are provided on the lower side of the outer shell 1. The mounting screws 18 are hand-tightened screws, which are convenient for later disassembly, thereby facilitating the cleaning of impurities or foreign matter in the collection box 16 and improving ease of use.

[0027] Among them, an inspection door is arranged on the upper side of the shell 1, and the inspection door can be conveniently arranged to inspect and replace the generator set body 3 or other components inside the shell 1, thereby ensuring the continuous normal use of the device.

[0028] Embodiment: During the use of the utility model, first, the driving motor 8 can drive the rotating shaft 4 and the cooling fan 5 to rotate. The cooling fan 5 rotates to blow air to the generator set body 3, thereby dissipating heat and cooling the generator set body 3. The air enters the shell 1 through the air inlet 12, and the hot air is discharged through the air outlet 13. At the same time, since the cooling fan blows air through the conical air duct 10, the wind speed blown out through the exhaust port 11 is accelerated due to the change of the air duct, thereby accelerating the wind blown out of the generator set body 3. The corresponding heat dissipation and cooling effect is also enhanced with the increase in wind speed, so that the hot air is quickly discharged through the air outlet 13. At the same time, since the rotating shaft 4 drives the turntable 6 and the cleaning brush 7 to rotate, the cleaning brush 7 can clean the dust and impurities on the air inlet 12, ensuring the continuous ventilation effect of the shell 1, thereby improving the heat dissipation and cooling effect of the generator set body 3.
