[0002] Wind power generation, as a clean renewable energy source, has the characteristics of no pollution, less land occupation, large reserves, and short investment. In recent years, it has developed rapidly around the world. Wind power generation is an electromechanical device that converts wind energy into mechanical energy and then converts mechanical energy into electrical energy. It usually consists of a wind turbine, a wind-aligning device, a speed-regulating device, a transmission device, a generator, a tower, a parking mechanism, etc. The end cover is an important component of the wind turbine.

[0003] In the patented document with the authorized publication number of CN219740116U, a wind turbine end cover capable of enhancing the heat dissipation effect is disclosed, including a cover body. The outer diameter of the inner wall at the bottom end of the cover body is fixedly connected with a support frame. The top end of the inner diameter of the support frame is fixedly connected with a frustum-shaped filter screen. A storage groove is arranged on the inner wall at the bottom end of the support frame near the outside of the frustum-shaped filter screen. The outer diameter of the top end of the support frame is fixedly connected with a plurality of connecting cylinders. The inner walls of the connecting cylinders are all slidably connected with telescopic columns. The bottom end of the telescopic column is fixedly connected with a sliding ring. An installation ring is arranged inside the inner diameter of the sliding ring. In the utility model, by setting a micro fan and a telescopic column, when the inner wall of the end cover is assembled on the outer wall of the generator, the sliding ring can be squeezed by the telescopic column to contract into the inner wall of the connecting cylinder, so that the micro fan is attached to the generator assembly to enhance the heat dissipation effect and keep the generator working normally.

[0030] Please refer to Figures 1-4 , the present utility model provides a technical solution: an end cover of a wind turbine that can enhance the heat dissipation effect, including a cover body 1. A plurality of air inlet holes 8 are provided on the outer wall of the cover body 1. The plurality of air inlet holes 8 are inclined and extend into the inner wall of the cover body 1. A rotating rod 3 is rotatably installed in the inner wall of the cover body 1. The rotating rod 3 extends to the outside of the cover body 1. A plurality of rotating plates 6 are fixedly installed on the outer wall of the rotating rod 3 located inside the cover body 1. The positions of the plurality of rotating plates 6 correspond to the positions of the plurality of air inlet holes 8. A plurality of second fan blades 7 are fixedly installed on the outer wall of the rotating rod 3 located inside the cover. An auxiliary rotating mechanism is provided above the cover body 1. A support rotating mechanism for supporting the rotation of the rotating rod 3 is provided inside the cover body 1. The auxiliary rotating mechanism includes an extension cover 2. The extension cover 2 is fixedly installed on the outer wall of the cover body 1. A plurality of ventilation holes 4 are respectively provided on the outer walls of the extension cover 2 and the cover body 1 on the same side. The rotating rod 3 is rotatably installed with the extension cover 2. A plurality of first fan blades 5 are fixedly installed on the outer wall of the rotating rod 3 located inside the extension cover 2.

[0031] In the technical solution of the present utility model, the cover body 1 and the support rotating mechanism can play a role in rotatably supporting the rotating rod 3. The plurality of air inlet holes 8 on the outer wall of the cover body 1 are provided, and the air inlet holes 8 are inclined and extend into the inner wall of the cover body 1, so that wind from more directions can blow into the inside of the cover body 1, thereby making the wind act on the rotating plate 6 to rotate, and then driving the second fan blades 7 to rotate, so that the second fan blades 7 can better dissipate heat from the generator. Moreover, the auxiliary rotating mechanism can play a role in rotating the rotating rod 3, driving the second fan blades 7 to dissipate heat inside the generator, and then enhancing the heat dissipation effect.

[0032] In addition, the cover body 1 can play a role in fixing the extension cover 2, and the ventilation holes 4 can play a role in air inlet for the cover body 1 and the extension cover 2. The air inlet through the ventilation holes 4 can act on the first fan blades 5 to rotate, and then the first fan blades 5 drive the rotating rod 3 to rotate, and the rotating rod 3 can drive the second fan blades 7 to rotate.

[0033] In the technical solution of the present utility model, as Figure 1 andFigure 4 As shown, a fixing ring 11 is fixedly installed on the inner wall of the cover body 1, and the fixing ring 11 is located on one side of the second fan blade 7. The cover body 1 can fix the fixing ring 11. On the side of the fixing ring 11 away from the second fan blade 7, a filter screen 12 is fixedly installed by bolts. The inner wall of the filter screen 12 is rotatably connected to the rotating rod 3. Through the cooperation of the bolts, the filter screen 12 can be installed on one side of the fixing ring 11, and then the filter screen 12 can filter the wind.

[0034] In the technical solution of the present utility model, as Figure 1 and Figure 2 shown, the support rotating mechanism includes two support rods 9. The two support rods 9 are fixedly installed on the inner wall of the cover body 1. The cover body 1 can fix the support rods 9. On the opposite sides of the two support rods 9, a bearing 10 is fixedly installed. The inner ring wall of the bearing 10 is fixedly installed with the rotating rod 3, and the bearing 10 is located between multiple groups of rotating plates 6 and multiple groups of second fan blades 7. The support rods 9 can fix the bearing 10, and the rotating rod 3 can install the bearing 10, so that the support rods 9 can support the rotating rod 3 to rotate in cooperation with the bearing 10.

[0035] In the technical solution of the present utility model, as Figure 1 shown, two lugs 13 are fixedly connected to the outer wall of the cover body 1. The cover body 1 can fix the lugs 13, and the setting of the lugs 13 can install the cover body 1.

[0036] During use, first, the support rods 9, the bearing 10, the cover body 1, the filter screen 12 and the extension cover 2 can support the rotating rod 3 to rotate. Then, in the traditional air inlet mode, air can enter through the ventilation holes 4, so that the air entering through the ventilation holes 4 can rotate the first fan blade 5. The first fan blade 5 can drive the rotating rod 3 to rotate, and the rotating rod 3 can drive the second fan blade 7 to rotate, so that the second fan blade 7 can play a traditional heat dissipation role for the generator. However, when the wind direction changes, the heat dissipation effect will be reduced due to the setting of the ventilation holes 4;

[0037] Therefore, multiple groups of air inlet holes 8 on the outer wall of the cover body 1 can better play the role of air inlet, and the air inlet holes 8 extend obliquely into the inner wall of the cover body 1, so that more directions of wind can blow into the interior of the cover body 1, so that the wind can rotate the rotating plate 6, and then drive the second fan blade 7 to rotate, so that the second fan blade 7 can better play a role in enhancing the heat dissipation of the generator, and the filter screen 12 can filter the incoming wind;

[0038] In summary, this end cover of the wind turbine generator that can enhance the heat dissipation effect realizes the effective heat dissipation of the interior of the generator and improves the overall performance of the wind turbine generator by reasonably utilizing the wind force, designing reasonable air inlet holes 8 and rotating mechanisms.
