[0031] According to the above embodiment, the arc-shaped hole can facilitate the gear 292 to enter the interior of the housing 21, thereby facilitating the meshing connection between the row of teeth 2910 inside the housing 21 and the gear 292, thereby increasing the connection stability of the device;

[0032] The adjustment assembly 29 further includes three limit plates 293 fixed to the inner wall of the housing 21. A support plate 296 is slidably connected between the limit plates 293 and one side of the support housing 291. One side of the support plate 296 is fixedly connected to two rows of teeth 2910. One side of the support plate 296 is fixedly connected to one side of the slider 295.

[0033] The rows of teeth 2910 are meshed with the gear 292 , and one side of each row of teeth 2910 is slidably connected to the outer surface of the limiting plate 293 ;

[0034] According to the above embodiment, the gear 292 is controlled to rotate by the row of teeth 2910, and the gear 292 is driven to rotate by the movement of the row of teeth 2910. The gear 292 is driven to rotate and the shaft 23 is driven to rotate, thereby achieving the effect of driving the rotating plate 24 to rotate, thereby increasing the linkage between the parts of the equipment.

[0035] The adjustment assembly 29 further includes a rotating rod 297 rotatably connected to the interior of the housing 21 , and a threaded groove 298 is formed on the outer surface of the rotating rod 297 ;

[0037] Through the above embodiment, the threaded tube 299 is fixed to the slider 295, and the slider 295 forms a first limit with the support plate 296. The slider 295 slides on the inner wall of the sliding hole 294 to form a second limit, thereby preventing the threaded tube 299 from rotating. Then, the rotation of the rotating rod 297 can drive the threaded tube 299 to move through the thread groove 298. The limit of the sliding hole 294 prevents the threaded tube 299 from moving to separate from the thread groove 298.

At the same time, the cover plate 2911 and the rotating hole 2912 can limit the rotating rod 297, thereby increasing the structural stability of the rotating rod 297.

[0041] Working principle:

[0042] like Figure 1-6As shown, in use, first determine the model of the pool wall 1 and the channel 3, select the mounting plate 214 adapted to the pool wall 1 and the size of the adjustment scraper device 2, after the selection is completed, turn the handle 2913 to drive the rotating rod 297 to rotate, because the slider 295 forms a first limit with the support plate 296, the slider 295 slides on the inner wall of the sliding hole 294 to form a second limit, so that the threaded tube 299 cannot rotate, and then the rotation of the rotating rod 297 can drive the threaded tube 299 to move through the thread groove 298, and the threaded tube 299 cannot move to separate from the thread groove 298 due to the limit of the sliding hole 294, and the threaded tube 299 drives the support plate 296 to move through the slider 295. The rotation of the rod 297 rotates the threaded tube 299, and the movement of the threaded tube 299 drives the slider 295 to move. The movement of the slider 295 drives the support plate 296 to move. The movement of the support plate 296 drives the row of teeth 2910 to move. The movement of the row of teeth 2910 drives the gear 292 to rotate. The rotation of the gear 292 drives the shaft 23 to rotate. The rotation of the shaft 23 drives the rotating plate 24 to rotate. The rotation of the rotating plate 24 drives the template 25 to move along the axis of the shell 21. The movement of the template 25 drives the scraper 26 to contact the inner wall of the channel 3. Then, the rotation of the handle 2913 is stopped. The self-locking nature of the thread can fix the scraper 26. At this time, the position from the outer edge of the scraper 26 to the axis of the shell 21 is the radius of the channel 3.

[0043] Assemble, slide the sleeve 28 onto the outside of the shell 21, and rotate the threaded hole to align with the fixing hole 27, then fix the sleeve 28 to the shell 21 through the first bolt 215, and then fix the fixing plate 212 to one side of the connecting plate 211 through the second bolt 216, then fix the mounting plate 214 to one side of the pool wall 1, and make the shell 21 located inside the channel 3, and the water flows through the channel 3 through the fan blades 210 to drive the shell 21 to rotate, the rotation of the shell 21 drives the rotating plate 24 to rotate, the rotation of the rotating plate 24 drives the template 25 to rotate, and the rotation of the template 25 drives the scraper 26 to start working, thereby completing the cleaning work.
