[0003] For example, a wind turbine disclosed in Publication No. 202223079196.7 still has the following deficiencies in actual use:

[0004] When the above-mentioned wind turbine is in actual use, although the air is filtered, its safety protection ability is poor. When in a humid environment such as at sea, air or seawater with a high salt or moisture content can penetrate into the coil from the gaps, thus damaging the performance of the wind turbine. Moreover, the IP protection level of ordinary shaded-pole motors on the market can only reach IP40. With the popularization of marine electrical equipment, it is necessary to increase a series of requirements for salt spray resistance, waterproofing, explosion protection, etc. of shaded-pole motors. Utility Model Content

[0005] In order to improve the problem of insufficient protection performance, this application provides a wind turbine.

[0040] The following will further elaborate on this application in conjunction with the attached Figure 1-8 Provide a more detailed description of this application.

[0041] The embodiments of this application disclose a fan.

[0042] Refer to Figure 1, 2, A fan includes an outer frame 1. One side of the outer wall of the outer frame 1 close to the fan driver 11 is fixedly connected. One end of the outer wall of the fan driver 11 close to the motor cable 12 is fixedly connected, facilitating driving. A vacuum infusion mechanism 2 is provided inside the outer frame 1.

[0043] The staff installs the outer frame 1 at the reserved position, then fixes the fan driver 11 to the outer wall of the outer frame 1, fixes one end of the motor cable 12 to the fan driver 11, and the other end passes through the connecting piece 21 and is connected to the internal coil of the stator 22.

[0044] Refer to Figure 3 , 4, 5, The vacuum infusion mechanism 2 includes a stator 22. One side of the stator 22 close to the wrapping piece 25 is fixedly connected to one side of the wrapping piece 25 close to the stator 22, so as to separate the coil inside the stator 22 from the outside through the wrapping piece 25 and wrap the coil inside the stator 22. The top of the stator 22 is fixedly connected to one end of the connection end 24 close to the stator 22 to fix the connection end 24. A cylindrical hole one is opened inside the connection end 24, and the wind blade shaft 26 is inserted into the cylindrical hole one, so that the wind blade shaft 26 is rotatably connected to the connection end 24. A cylindrical hole two is opened inside the wrapping piece 25, and the cast aluminum rotor 27 is inserted into the cylindrical hole two, so that the cast aluminum rotor 27 is rotatably connected to the wrapping piece 25. One side of the cast aluminum rotor 27 away from the wrapping piece 25 is snap-connected to one side of the connection ring 28 close to the cast aluminum rotor 27, so as to limit the cast aluminum rotor 27 through the connection ring 28. The vacuum infusion mechanism 2 further includes a connecting piece 21 fixedly connected to the inner wall of the outer frame 1. A round hole one is opened on the side wall of the outer frame 1. A through hole is opened inside the connecting piece 21, and the round hole one is communicated with the through hole, so that the connecting piece 21 is connected to the outer frame 1. A round hole two is opened on the side wall of the stator 22. One end of the connecting piece 21 away from the outer frame 1 is communicated with the round hole two, so that one end of the motor cable 12 away from the fan driver 11 can pass through the side wall of the outer frame 1 and directly pass through the inside of the connecting piece 21 to the inside of the stator 22, so that the motor cable 12 is connected to the coil inside the stator 22. An injection port 23 is opened non-through on the top of the connecting piece 21. Refer to Figure 4 as shown, facilitating the injection of silicone into the stator 22.

[0045] Subsequently, the staff puts the mold on the top of the stator 22, then sucks the inside of the stator 22 to a vacuum state. Then the staff injects liquid thermal conductive silicone into the inside of the stator 22 through the injection port 23. The liquid thermal conductive silicone has fluidity in the liquid state, so as to completely wrap the coil. After the silicone is completely cooled and solidified, the mold is removed, so that the wrapping piece 25 is formed. Then the wind blade shaft 26 is inserted into the connection end 24, and at the same time, the cast aluminum rotor 27 is inserted into the wrapping piece 25.

[0046] Refer to Figure 5-8, one side of the connecting ring 28 far from the cast aluminum rotor 27 is fixedly connected to one side of the wind blade rotor 29 close to the connecting ring 28. The outer wall of the wind blade rotor 29 is fixedly connected to one side of the blade 210 close to the wind blade rotor 29, so that the wind blade rotor 29 can drive the blade 210 to rotate. The wind blade rotor 29 is made of stainless steel, so it has corrosion resistance. The outer walls of the wind blade rotor 29 and the blade 210 are both treated by electrophoresis, so that the performance is more excellent. The blade 210 is arc-shaped and inclined at an angle of 30°. The blade 210 is made by die-casting magnesium alloy in one piece, so as to facilitate driving the air to flow. The connecting hole 211 is non-penetratingly opened on one side of the wind blade rotor 29 far from the connecting ring 28, which is convenient for connection. The steel plate 212 is clamped on the inner wall of the connecting hole 211. The steel plate 212 is flush with one side of the wind blade rotor 29 far from the connecting ring 28, so as to reduce wind resistance. The screw 213 is made of stainless steel, so it has corrosion resistance. The screw 213 threadedly penetrates through the top of the steel plate 212, and the screw 213 threadedly penetrates through the top of the connecting hole 211, so that the steel plate 212 and the connecting hole 211 can be fixedly connected by the screw 213. One end of the screw 213 that threadedly penetrates and extends to the other side is threadedly connected to one side of the cast aluminum rotor 27 close to the wind blade rotor 29, so that the cast aluminum rotor 27 and the wind blade rotor 29 can be fixedly connected by the screw 213. The arc-shaped groove 214 is non-penetratingly opened on the side wall of the blade 210, which is convenient for the staff to install the components.

[0047] Afterwards, the staff starts the fan driver 11. The fan driver 11 will drive the coil inside the stator 22 through the motor cable 12. Subsequently, the cast aluminum rotor 27 will rotate. The cast aluminum rotor 27 will drive the wind blade rotor 29 to rotate, and the wind blade rotor 29 will drive the blade 210 to rotate, so as to output wind power.

[0048] The implementation principle of a fan in an embodiment of the present application is as follows:

[0049] The staff first sets the mold on the top of the stator 22, and then pours liquid thermal conductive silicone into the stator 22 through the injection port 23 to completely wrap the coil. After the silicone is completely cooled, the mold is removed, so that the wrapped part 25 solidifies and forms. Subsequently, the wrapped part 25 is inserted into the cast aluminum rotor 27, and the connecting end 24 is inserted into the wind blade shaft 26. Then the fan driver 11 is started. The fan driver 11 will drive the cast aluminum rotor 27 to rotate through the stator 22. The cast aluminum rotor 27 will drive the wind blade rotor 29 to rotate, and then drive the blade 210 to rotate through the wind blade rotor 29.

[0050] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
