A drive plate 2 is fixedly connected to the outside of the second pipe 1. A moving component is provided between the drive plate 2 and the installation plate 4. Two vertical slots 26 are opened on the outside of the first pipe 3. A slider 27 is slidably connected inside the two vertical slots 26. One end of the two sliders 27 is fixedly connected to the top of the second pipe 1. The sliders 27 slide inside the vertical slots 26 to facilitate the stable movement of the second pipe 1 outside the first pipe 3. One end of the installation block 21 is installed inside the connecting slot 16, and one end of the insertion rod 13 is installed inside the insertion hole 28.

[0026] like Figure 3 As shown, the clamping assembly includes a movable block 14, which is slidably connected to the inside of the connecting groove 16. A rod 13 is fixedly connected through the inside of the movable block 14. One end of the rod 13 extends through to the outside of the first connecting plate 8. A first spring 19 is sleeved on the outside of the rod 13. The two ends of the first spring 19 are fixedly connected to one side of the movable block 14 and the inside of the connecting groove 16, respectively. The clamping assembly facilitates the clamping and fixing of the installed mounting block 21. Both positioning assemblies include a connecting frame 18, which is fixedly connected to one end of the rod 13. A pressing block 17 is rotatably connected inside the connecting frame 18. The positioning assembly allows the rod 13 to be pulled and fixed after the pressing block 17 rotates.

[0027] like Figure 3 and Figure 4 As shown, a first sealing ring 15 is fixedly connected to one side of the first connecting plate 8, and a second sealing ring 20 is fixedly connected to one side of the second connecting plate 9. Both the first sealing ring 15 and the second sealing ring 20 are made of rubber to ensure that the connection between the first connecting plate 8 and the second connecting plate 9 maintains a sealing effect.

[0028] like Figure 1 and Figure 2 As shown, the moving component includes a vertical plate 12, one end of which is fixedly connected to one side of the mounting plate 4. Two transmission wheels 5 are rotatably connected to one side of the mounting plate 4. A belt 7 is mounted on the outside of the two transmission wheels 5. A connecting block 6 is fixedly connected to one side of the belt 7. One side of the connecting block 6 is fixedly connected to one side of the drive plate 2. A self-locking motor 11 is fixedly connected to one side of the vertical plate 12. The self-locking motor 11 is connected to an external control box. The output end of the self-locking motor 11 passes through the vertical plate 12 and is fixedly connected to one end of one of the transmission wheels 5. The moving component facilitates the downward movement of the second pipe 1 and makes it easy to adjust the descent height of the hood body 10.

[0029] like Figure 4 and Figure 5 As shown, the mounting assembly includes a connecting rod 25, with both ends of the connecting rod 25 fixedly connected to the inner side of the transverse groove 22. A driving block 24 is slidably connected to the outside of the connecting rod 25, with the outer side of the driving block 24 slidably connected to the inner side of the transverse groove 22. A mounting block 21 is fixedly connected to one end of the driving block 24, and an insertion hole 28 is provided on one side of the mounting block 21. A second spring 23 is mounted on the outside of the connecting rod 25, with both ends of the second spring 23 fixedly connected to one side of the driving block 24 and one side of the transverse groove 22. The mounting assembly facilitates the assembly and connection of the first connecting plate 8 and the second connecting plate 9.

[0030] Working principle: When removing the wind cover body 10, the clamping block 17 is rotated to keep one end of the clamping block 17 horizontal with the first connecting plate 8. After the clamping block 17 rotates, it drives the insertion rod 13 to move. After the insertion rod 13 moves, it drives the moving block 14 to move. After the moving block 14 moves, it compresses the first spring 19, which can separate the insertion rod 13 from the insertion hole 28, making it easy to detach the mounting block 21 from the inside of the connecting groove 16. This allows for the disassembly and assembly of the wind cover body 10. When installing the wind cover body 10, the first connecting plate 8 and the second connecting plate 9 are connected so that the first sealing ring 15 and the second sealing ring 20 contact to ensure a seal. The mounting block 21 is installed into the inside of the connecting groove 16. When the clamping block 17 is released, the insertion rod 13 is driven to be installed inside the insertion hole 28 under the action of the first spring 19, and the mounting block 21 drives the driving block 24 to move. After the driving block 24 moves, it drives the second spring 23 to stretch, so that the insertion rod 13 is more firmly locked to the mounting block 21. When the second pipe 1 is extended or retracted, the self-locking motor 11 is controlled by the external control box. The self-locking motor 11 drives the transmission wheel 5 to rotate. The rotation of the transmission wheel 5 drives the belt 7 to rotate. After the belt 7 rotates, it drives the connecting block 6 to move. After the connecting block 6 moves, it drives the driving block 24 to realize the extension or retraction of the second pipe 1 outside the first pipe 3, which is very convenient for adjusting the height of the hood body 10.
