The mounting frame is first disengaged from the lifting plate, so that the semicircular blocks on both sides can move to both sides by pulling the rope, thereby releasing the limit on the arc block. At this time, the hook is in contact with the hanging ring, and the arc block matching it is pulled upward and fixed by the first magnet.

A clamping block 23, a long plate 24 and a mounting frame 25 are provided on the cover plate 11. The airbag 22 and the clamping block 23 are both between the sealing grooves. The long plate 24 is slidably mounted on the top of the cover plate 11. Hooks 26 are provided on both sides of the bottom of the long plate 24. A protective component 27 and an auxiliary component 28 are provided inside the protective frame 21 and below the hook 26. The protective component 27 can wrap the connection between the main shaft 12 and the chassis 10 to prevent water leakage. At the same time, the worn rubber sheet inside the protective component 27 can be replaced, and the tightness of the protective component 27 can be improved by cooperating with the auxiliary component 28. The protective assembly 27 further includes a stabilizing component 30 disposed at the bottom thereof. The stabilizing component 30 includes a square plate 31 used in conjunction with the protective assembly 27. The square plate 31 is fixedly mounted on the lifting plate 28b. A limiting plate 32 is symmetrically mounted on the inner wall of the protective frame 21. A support rod 33 is slidably connected to the limiting plate 32. A first rack 34 is fixedly connected to the support rod 33. The top end of the first rack 34 contacts the bottom end of the square plate 31. A third spring 35 is disposed between the support rod 33 and the limiting plate 32. The reaction force of the third spring 35 enables the support rod 33 to drive the first rack 34 to reset. A moving component 36 is disposed on one side of the first rack 34, as well as a cleaning component 37 used in conjunction with the moving component 36.

[0026] In further detail, the protective assembly 27 includes a circular plate 27a fixedly mounted on the inner wall of the protective frame 21, each circular plate 27a is provided with a semicircular block 27b and an arc block 27c, and a plurality of first rollers 27d are provided on the surface of the arc block 27c. The first rollers 27d enable the semicircular block 27b to reduce the friction between the arc block 27c and the semicircular block 27b after the arc block 27c is clamped and fixed, thereby reducing wear. A first magnet 27e is fixedly mounted on the top of one side of the circular plate 27a close to the arc block 27c, and the first magnet 27e can adsorb and fix the top arc block 27c, and at the same time, hanging rings are installed on both sides of the top arc block 27c.

[0027] In further detail, the semicircular block 27b and the arc block 27c are symmetrically arranged on the circular plate 27a, and the two semicircular blocks 27b slide left and right. Each arc block 27c is provided with a semicircular groove on the side close to the circular plate 27a, and the semicircular grooves are merged to form a circular groove. Slide blocks are provided at both ends of one of the semicircular grooves, and the slide block is slidably installed on the circular plate 27a. The end of the slide block close to the semicircular groove is spherical. By setting this end to a spherical shape, the slide block will not affect the two arc blocks 27c when they rotate. The inner ring of each arc block 27c is provided with a rubber pad, and the connection between the main shaft 12 and the chassis 10 is wrapped by the rubber pad to prevent water vapor from entering.

[0028] Operation process: When the main shaft 12 starts to rotate, the friction force will also drive the merged arc block 27c to rotate synchronously. During the rotation, the rubber pad will also be worn to a certain extent. Therefore, it needs to be replaced after a period of use. First, the screws between the cover plate 11 and the protective frame 21 are unscrewed, and then the long plate 24 is pushed to move the hook 26 to the bottom of the hanging ring. At this time, the cover plate 11 is pulled upward, so that the cover plate 11 drives the hook 26 and the mounting frame 25 to rise. The mounting frame 25 is first disengaged from the auxiliary component 28, so that the semicircular blocks 27b on both sides can move to both sides, thereby releasing the limit of the arc block 27c. At this time, the hook 26 contacts the hanging ring and pulls the matching arc block 27c upward; When the slider is pulled, it is driven to rise, and the slider acts as a limit to the moving arc block 27c, so that it is disengaged from the bottom arc block 27c. After the arc block 27c rises to the top, it is adsorbed and fixed by the first magnet 27e. At this time, the long board 24 is pushed to reset, so that the hook 26 is disengaged from the hanging ring. At this time, the worn rubber pad placed on the inner ring of the arc block 27c can be pulled out and replaced. After the replacement is completed, the cover plate 11 and the chassis 10 are assembled and the screws are tightened to fix them. At the same time, the block 23 at the bottom of the cover plate 11 will be located between the sealing grooves and squeeze the airbag 22, causing the airbag 22 to deform and fill the remaining gaps between the cover plate 11, the protective frame 21 and the chassis 10, thereby increasing the sealing performance. At the same time, the mounting frame 25 contacts the auxiliary component 28 again, so that the two semicircular blocks 27b move toward the opposite surface, and squeeze the arc block 27c on the top while moving, so that it is no longer adsorbed by the first magnet 27e, and descends to engage with the arc block 27c at the bottom. At the same time, the semicircular blocks 27b on both sides will also merge together, so that the merged arc block 27c is squeezed and fixed, and the merged arc block 27c will clamp the main shaft 12, and at the same time, the rubber pad can increase the sealing performance between the main shaft 12 and the arc block 27c, prevent water vapor from entering the inside of the chassis 10, and improve the waterproof performance of the chassis 10; At the same time, after the semicircular block 27b clamps and fixes the arc block 27c, the friction between the arc block 27c and the semicircular block 27b is reduced through the first roller 27d, and the rotation speed of the main shaft 12 is not affected by the friction, thereby reducing wear.

[0029] like Figure 7 - Figure 8 As shown, the auxiliary component 28 includes a fixing frame 28a symmetrically mounted on the inner wall of the protective frame 21, a lifting plate 28b is slidably connected to one side of the fixing frame 28a, and a first spring 28c is fixedly connected between the lifting plate 28b and the fixing frame 28a. When the lifting plate 28b is lifted and lowered by the pressing of the mounting frame 25, the first spring 28c is also pressed, and the reaction force of the first spring 28c enables the lifting plate 28b to be reset, and the bottom end of the lifting plate 28b is fixedly connected to a plurality of second springs 28c. The roller 28d and the inner wall of the protective frame 21 are symmetrically installed with a winding wheel 28e, and are located below the fixed frame 28a. A rope 28f is wound around the winding wheel 28e. A cross plate 28g and a second spring 28h are symmetrically arranged on one side of the outer wall of the chassis 10 close to the semicircular block 27b. The second spring 28h is arranged between the partition 21 and the cross plate 28g. The cross plate 28g can be raised and lowered by the traction of the rope 28f, and the cross plate 28g can be reset by the reaction force of the second spring 28h.

[0030] In further detail, the bottom end of the lifting plate 28b is inclined, and a plurality of second rollers 28d are equidistantly arranged. The second rollers 28d are in contact with the top of the semicircular block 27b. When the lifting plate 28b is lifted or lowered, the semicircular block 27b is squeezed by the second rollers 28d at the bottom. The friction between the lifting plate 28b and the semicircular block 27b is reduced by the second rollers 28d, thereby reducing wear. One end of the rope 28f is connected to the semicircular block 27b, and the other end of the rope 28f is connected to the cross plate 28g. One side of the mounting frame 25 is connected to the top of the lifting plate 28b. When the semicircular block 27b moves toward the opposite surface, it will also stretch the rope 28f, so that the other end of the rope 28f will pull the horizontal plate 28g upward. At this time, the second spring 28h will be pulled up. If the lifting plate 28b rises and gradually separates from the semicircular block 27b, the horizontal plate 28g will be pulled back to its original position through the reaction force of the second spring 28h, and the semicircular block 27b will be pulled to both sides through the rope 28f. The interior of the semicircular block 27b is hollow, thereby reducing the overall weight of the semicircular block 27b so that it can be pulled by the rope 28f.

[0031] Operation process: After the mounting frame 25 rises with the cover plate 11, the mounting frame 25 will gradually break away from the top of the lifting plate 28b. At this time, the lifting plate 28b is pulled up by the reaction force of the first spring 28c. While the lifting plate 28b is rising, the slope of the inclined surface at the bottom will gradually decrease. At this time, there will be a gap between the semicircular block 27b. The reaction force of the second spring 28h will pull the horizontal plate 28g to reset, and the semicircular block 27b will be pulled to both sides by the rope 28f, so as to release the limit of the arc block 27c. On the contrary, if the mounting frame 25 follows the cover plate 11 to descend, the mounting frame 25 contacts the top of the lifting plate 28b and pushes it downward. When the lifting plate 28b descends, the semicircular block 27b is squeezed by the second roller 28d at its bottom. The friction between the lifting plate 28b and the semicircular block 27b is reduced by the second roller 28d, thereby reducing wear, so that the semicircular blocks 27b on both sides can move toward the opposite surfaces, squeezing the arc block 27c to merge them while moving, and at the same time pulling the rope 28f to pull the horizontal plate 28g up.

[0032] like Fig. 9 - Fig.10As shown, the moving assembly 36 includes a connecting frame 36a symmetrically installed on the inner wall of the protective frame 10, a fixing plate 36b is fixedly installed on one side of the connecting frame 36a, a gear 36c is rotatably connected to the fixing plate 36b, a stop block 36d is slidably connected to the top of the fixing plate 36b, and the stop block 36d is further slidably connected to the fixing effect of the semicircular block 27b, so that the arc block 27c can be stably clamped and fixed, a second rack 36e is fixedly connected to one side of the stop block 36d, an extension plate 36f is fixedly connected to the bottom end of the stop block 36d, and the extension plate 36f is in an "L" shape, moving plates 36g are slidably connected to both sides of the circular plate 27a, a rectangular plate 36h is slidably connected to the circular plate 27a, and positioning columns 36i are symmetrically installed on the top of the rectangular plate 36h.

[0033] In further detail, the connecting frame 36a is tilted, the gear 36c is meshed with the first rack 34 and the second rack 36e, the size of the first rack 34 is only half of the gear 36c, the second rack 36e is the same size as the first rack 34, and is staggered, and the two racks do not contact each other, the side of the block 36d close to the semicircular block 27b is set as an inclined surface, the top of the connecting frame 36a is provided with a moving groove, the moving groove is connected to the bottom of the connecting frame 36a, the block 36d and the extension plate 3 6f is located between the movable grooves. When the lifting plate 28b descends, the square plate 31 is also driven to descend, thereby squeezing the top of the first rack 34, causing the first rack 34 to descend, and the gear 36c is rotated through meshing, and the second rack 36e drives the stop block 36d to move toward the semicircular block 27b, thereby squeezing and fixing the semicircular block 27b from both sides of the bottom end thereof, and cooperating with the lifting plate 28b so that the semicircular block 27b can better clamp and fix the arc block 27c.

[0034] In further detail, one side of the movable plate 36g close to the rectangular plate 36h is set as an inclined surface, and the rectangular plate 36h is located between the two movable plates 36g. The movable plate 36g and the rectangular plate 36h are both set below the semicircular block 27b. A positioning hole is provided at the bottom end of the semicircular block 27b. The size of the positioning column 36i is consistent with the positioning hole. When the second rack 36e moves, it will also drive the extension plate 36f to move, so that the extension plate 36f pushes the movable plate 36g, allowing the movable plates 36g on both sides to move toward the opposite surfaces. While moving, the rectangular plate 36h is squeezed by the inclined surface, so that the rectangular plate 36h drives the positioning column 36i to rise and engage with the positioning hole, thereby further enhancing the fixing effect of the semicircular block 27b.

[0035] Operation process: When the lifting plate 28b descends, the square plate 31 is also driven to descend, thereby squeezing the top of the first rack 34, causing the first rack 34 to descend, and the gear 36c is rotated through meshing, and the second rack 36e drives the stop block 36d to move toward the semicircular block 27b, thereby squeezing and fixing the semicircular block 27b from both sides of the bottom end thereof, and cooperating with the lifting plate 28b, the semicircular block 27b can better clamp and fix the arc block 27c; When the second rack 36e moves, the extension plate 36f is also driven to move, so that the extension plate 36f pushes the movable plate 36g, so that the movable plates 36g on both sides move toward the opposite surface, and the rectangular plate 36h is pressed by the inclined surface during the movement, so that the rectangular plate 36h drives the positioning column 36i to rise and engage with the positioning hole, thereby further improving the fixing effect of the semicircular block 27b; When the lifting plate 28b is reset, the reaction force of the third spring 35 will also cause the first rack 34 to rise, and at the same time, the gear 36c will rotate in the opposite direction through meshing, so that the second rack 36e drives the stop block 36d to move to both sides, and the height gradually decreases during the movement, and no longer contacts the semicircular block 27b, and the moving plate 36g will no longer be squeezed by the extension plate 36f. At this time, the rectangular plate 36h and the positioning column 36i are reset by gravity and squeeze the moving plate 36g to both sides, thereby releasing the limit on the semicircular block 27b.

[0036] like Fig.11 - Fig.12 As shown, the cleaning assembly 37 includes scrapers 37a symmetrically arranged between the protective frame 21 and the chassis 10, and second magnets (not marked in the figure) are arranged on the opposite surfaces of the two scrapers 37a. The two second magnets are magnetically attracted to each other, and an extension frame 37b is fixedly connected to one side of the scraper 37a. A connecting piece 37c is arranged between the top of the extension frame 37b and the bottom end of the extension plate 36f. A rotating rod 37d is fixedly connected between the protective frame 21 and the chassis 10, and a rotating plate 37e is rotatably connected to the rotating rod 37d. A through groove 37f is opened inside the protective frame 21.

[0037] In further detail, grooves are symmetrically provided at the bottom end of the inner wall of the protective frame 21, and the grooves are located directly below the rotating plate 37e and in contact with the bottom end of the rotating plate 37e, and the scraper 37a fits in the grooves, and the connecting piece 37c is connected to the extension frame 37b and the extension plate 36f through a hinge seat, and the middle part of the connecting piece 37c is configured to be retractable, and a torsion spring is provided between the rotating plate 37e and the rotating rod 37d, and the rotating plate 37e is made of rubber, and the through groove 37f is provided in the groove, and the through groove 37f is opened in the groove, and the through groove 37f is opened in a curved manner. The scraper 37a is pulled by the connecting piece 37c, so that the two scrapers 37a are separated and moved to both sides. While moving, the surface of the groove is cleaned by the scraper 37a, and impurities or residual water are pushed into the through groove 37f and discharged to the outside of the protective frame 21 through the through groove 37f. 37a will also contact with the rotating plate 37e, and as the scraper 37a moves, it will also squeeze one end of the rotating plate 37e to lift it up. When the scraper 37a is reset through the connecting piece 37c, the two scrapers 37a are attracted to each other by the magnetic attraction of the second magnet, so that the two scrapers 37a can be adsorbed together and stay in the middle of the groove, and the rotating plate 37e is reset by the torsion spring, so that the bottom end of the rotating plate 37e contacts and collides with the groove. The vibration force generated by the collision prevents impurities from accumulating at the curved part of the through groove 37f. Setting the through groove 37f to a curved shape has the following advantages: in some cases, the curved through groove 37f can prevent water from flowing back from the drainage system to the inside of the protective frame 21. At the same time, the curved through groove 37f can reduce the flow of air through the through groove 37f, which helps to maintain the air pressure and environmental stability inside the protective frame 21.

[0038] Operation process: When the extension plate 36f is reset, the scraper 37a is pulled by the connecting piece 37c, so that the two scrapers 37a are separated and move to both sides. While moving, the scraper 37a cleans the surface of the groove, and pushes the water vapor and impurities accumulated inside the groove into the through groove 37f, and discharges them to the outside of the protective frame 21 through the through groove 37f. At the same time, the scraper 37a will also contact the rotating plate 37e, and as the scraper 37a moves, it will also squeeze one end of the rotating plate 37e to lift it. When the scraper 37a is reset by the connecting piece 37c, the two scrapers 37a are attracted together and stay in the middle of the groove through the magnetic attraction of the second magnet, and the rotating plate 37e is reset by the torsion spring, so that the bottom end of the rotating plate 37e contacts and collides with the groove, and the vibration force generated by the collision prevents impurities from accumulating at the bend of the through groove 37f.
