[0021] Example

[0022] refer to Figures 1 to 4 This embodiment describes a ventilation structure for a wind turbine generator, comprising a base plate 1. A column 2 is fixedly connected to one side of the top of the base plate 1. A wind turbine generator set 3 is fixedly connected to the top of the column 2. A fan blade 4 is fixedly connected to the output end of the wind turbine generator set 3. A generator control box 5 is fixedly connected to one side of the top of the base plate 1. Ventilation windows 6 are provided on both sides of the generator control box 5. A dustproof net 7 is connected to one side of the interior of each ventilation window 6. The dustproof net 7 serves to prevent dust from entering the generator control box 5 and also ensures normal airflow. A cleaning brush 8 is attached to one side of the dustproof net 7. Springs 9 are fixedly connected to both sides of one end of the cleaning brush 8. A mounting bracket is fixedly connected to the side of the spring 9 away from the cleaning brush 8. Mounting plate 10, a power assembly 13 is provided on one side of the generator control box 5, the mounting plate 10 is slidably connected to the inside of the generator control box 5 through the power assembly 13, the other side of the ventilation window 6 is connected to the mounting frame 141, a waterproof and breathable membrane 14 is fixedly connected inside the mounting frame 141, a fixing assembly 16 is provided on one side of the mounting frame 141, a baffle 15 is connected to one side of the mounting frame 141 through the fixing assembly 16, an assembly block 17 is fixedly connected to one side of the baffle 15, and an mounting assembly 18 is provided between the assembly block 17 and the generator control box 5. Through the above improvements, the service life of the cleaning brush can be extended and water vapor intrusion can be prevented, ensuring that the wind turbine generator set 3 can maintain efficient and stable operation under various environmental conditions.

[0023] refer to Figure 4The cleaning brush 8 has a first slide rod 11 fixedly connected to both sides of one end, and a second slide rod 12 fixedly connected to the side of the cleaning brush 8 near the first slide rod 11. Both the first slide rod 11 and the second slide rod 12 are slidably connected to the mounting plate 10. By setting the first slide rod 11 and the second slide rod 12, the cleaning brush 8 moves more stably under the action of the spring 9, avoiding the deformation of the spring 9 that causes the cleaning brush 8 to shift its position, thus facilitating the cleaning of the dust screen 7 by the cleaning brush 8.

[0024] refer to Figure 1 The power assembly 13 includes a drive motor 131, which is fixedly connected to the top of the generator control box 5. A lead screw 132 is fixedly connected to the output end of the drive motor 131. The lead screw 132 is rotatably connected inside the generator control box 5. A first threaded sleeve 133 is threaded onto the outer surface of the lead screw 132. A movable plate 134 is fixedly connected to one side of the first threaded sleeve 133. One side of the movable plate 134 is fixedly connected to one side of the mounting plate 10. A guide is fixedly connected to one side of the movable plate 134. A guide rod 135 is fixedly connected to the side of the generator control box 5 away from the lead screw 132. The guide block 136 is slidably connected to the guide rod 135. By setting the power component 13, the drive motor 131 drives the lead screw 132 to rotate. Under the action of the guide block 136 and the guide rod 135, the first threaded sleeve 133 on the surface of the lead screw 132 moves. The threaded sleeve drives the moving plate 134 to move, so that the moving plate 134 drives the cleaning brush 8 to move back and forth, which can unclog the dust screen 7 and avoid blockage that prevents the airflow from flowing normally.

[0025] refer to Figure 3 The fixing component 16 includes connecting rods 161, which are fixedly connected to the baffle 15. There are four connecting rods 161. A second threaded sleeve 162 is fixedly connected to one side of the connecting rod 161. A second stud 163 is threadedly connected to both sides of the mounting frame 141. The stud 163 is threadedly connected to the threaded sleeve. A rotating block 164 is fixedly connected to the end of the stud 163. By setting the fixing component 16, when it is necessary to remove the waterproof and breathable membrane 14 from one side of the baffle 15, the rotating block 164 is rotated. The rotating block 164 drives the stud 163 to rotate, so that the stud 163 leaves the threaded sleeve, and the waterproof and breathable membrane 14 can be removed and replaced.

[0026] refer to Figures 2-3The mounting assembly 18 includes slots 182, which are located on both sides of the generator control box 5. Insert blocks 181 are inserted into the slots 182 and are fixedly connected to the assembly block 17. Connecting holes 183 are provided inside the insert blocks 181, and connecting rods 184 are inserted into the connecting holes 183. Screws 186 are rotatably connected inside the generator control box 5. Slider blocks 185 are threaded onto the outer surface of the screws 186. Connecting rods 184 are fixedly connected to both sides of one end of each slider 185. The insert blocks 181... The internal connection hole 183 is provided, and one side of the connecting rod 184 is movably connected to the connection hole 183. The top end of the screw 186 is fixedly connected to the torsion block 187. By setting the installation assembly 18, when it is necessary to remove the waterproof and breathable membrane 14, first rotate the torsion block 187. The torsion block 187 drives the screw 186 to rotate, causing the slider 185 on its surface to move. The slider 185 drives the connecting rod 184 to move, so that the connecting rod 184 leaves the connection hole 183 in the insert block 181. At this time, the assembly block 17 is no longer fixed and can be removed, which facilitates the subsequent replacement of the waterproof and breathable membrane 14.

[0027] Operating principle and advantages: When cleaning the dust screen 7 of the ventilation window 6 is required, the motor drives the lead screw 132 to rotate. The threaded sleeve on the surface of the lead screw 132 rotates under force. The moving plate 134 connected to the threaded sleeve can move up and down horizontally under the action of the guide block 136 and the guide rod 135. This causes the moving plate 134 to move the mounting plate 10, which in turn moves the cleaning brush 8. The cleaning brush 8 is in close contact with the dust screen 7 under the action of multiple springs 9. The elastic contact extends the service life of the cleaning brush 8, reduces the replacement frequency, and also improves the cleaning effect. Moisture in the air is trapped inside the ventilation window 6. The waterproof and breathable membrane 14 acts as a barrier, protecting the generator set from damage by the humid environment and ensuring the stability of the entire wind power generation system. After the waterproof and breathable membrane 14 has been used for a period of time, the torsion block 187 is rotated, which drives the screw 186 to rotate, causing the slider 185 on its surface to move. The slider 185 drives the connecting rod 184 to move, causing the connecting rod 184 to leave the connecting hole 183 in the insert block 181. At this time, the assembly block 17 is no longer fixed. The baffle 15 is removed, and then the rotating block 164 is rotated to drive the stud 163 to leave the screw sleeve, so that the waterproof and breathable membrane 14 can be removed and replaced.
