[0029] It can be further explained that the rainwater entering the main body 1 of the treatment device is filtered by the filter plate 5, and the debris is filtered to the top of the filter plate 5. The scraper 404 that moves horizontally pushes the debris accumulated on the top of the filter plate 5, thereby ensuring the patency of the filter holes of the filter plate 5, thereby ensuring the filtering effect of the filter plate 5.

The top of the second moving rod 4041 extends to the top of the processing device body 1. The interior of the second moving rod 4041 is sleeved with a cross bar 4042. The two ends of the cross bar 4042 are fixedly connected to the top of the processing device body 1 by bolts.

[0031] It can be further explained that the output end of the driving motor 401 rotates to drive the threaded rod 402 to rotate, and the rotation of the threaded rod 402 drives the first moving rod 403 to move toward the end close to the water inlet 2, and the movement of the first moving rod 403 drives the scraper 404 to move, and the scraper 404 moves and drives the debris on the top of the filter plate 5 to move toward the end close to the blocking plate 410.

[0032] See also Figure 2 and Figure 3, one side of the first moving rod 403 is fixed with an extrusion block 405 by bolts, and a moving block 406 is sleeved inside the fixed box 3. The top of the moving block 406 extends to the top of the fixed box 3, and the top of the moving block 406 is inclined. When the extrusion block 405 moves and reaches one end of the moving block 406, the extrusion block 405 continues to move to squeeze the moving block 406 to move downward; the bottom end of the moving block 406 is fixed with a rack 407 by bolts, and one end of the rack 407 is engaged with a spur gear 408. A rotating rod 409 is welded to one side of the spur gear 408, and the rotating rod 409 is fixedly connected to the blocking plate 410 by bolts. The rotating rod 409 is rotatably connected to the processing device body 1 and the inner wall of the fixed box 3 through a bearing. The downward movement of the moving block 406 can drive the spur gear 408 to rotate clockwise through mechanical transmission, and then drive the blocking plate 410 to rotate clockwise, that is, the processing device One end of the main body 1 is open to facilitate the subsequent discharge of debris; the end of the rack 407 away from the spur gear 408 is fixed with a sliding block 4071 by a bolt, the interior of the sliding block 4071 is sleeved with a limiting column 4072, the bottom end of the limiting column 4072 is fixed with a fixed block 4073 by a bolt, one end of the fixed block 4073 is fixedly connected to the inner wall of the fixed box 3 by a bolt, the bottom end of the sliding block 4071 is fixedly connected with a spring 4074, the bottom end of the spring 4074 is fixedly connected to the top of the fixed block 4073, and the spring 4074 is sleeved on the outside of the limiting column 4072, the sliding block 4071 and the limiting column 4072 are used to limit the rack 407 to prevent the rack 407 from deviating in the horizontal direction, and the spring 4074 is used to support the rack 407 and the moving block 406, and the spring 4074 is used to provide a reset force for the moving block 406 to move in the vertical direction.

[0033] It can be further explained that when the extrusion block 405 moves and contacts one end of the moving block 406, the extrusion block 405 continues to move and squeezes the moving block 406 to move downward, the movement of the moving block 406 drives the rack 407 to move, the movement of the rack 407 drives the spur gear 408 to rotate clockwise, the spring 4074 is squeezed by force, the rotation of the spur gear 408 drives the rotating rod 409 to rotate, the rotation of the rotating rod 409 drives the blocking plate 410 to rotate, at this time one end of the processing device body 1 is opened, and the debris pushed by the scraper 404 is discharged through the rotating and opened blocking plate 410.

[0034] See also Figure 4 A guide plate 101 is fixed to the bottom end of the inner wall of the treatment device body 1 by bolts. The top of the guide plate 101 is inclined, and the guide plate 101 is located at one end of the water outlet 6. The guide plate 101 is used to guide the filtered rainwater to the water outlet 6, and then discharge the rainwater from the interior of the treatment device body 1 through the water outlet 6.

[0035] It can be further explained that the rainwater slides down to the top of the guide plate 101 , is guided to one end of the water outlet 6 by the guide plate 101 , and then the treated rainwater is discharged through the water outlet 6 .

[0036] Working principle: When in use, rainwater is first introduced into the interior of the treatment device body 1 through the water inlet 2. The rainwater introduced into the treatment device body 1 contacts the filter plate 5, and the impurities in the rainwater are filtered out by the filter plate 5. Then, the rainwater slides to the top of the guide plate 101, and is guided to one end of the water outlet 6 by the guide plate 101. Then, the treated rainwater is discharged through the water outlet 6.

[0037] Secondly, when a certain amount of debris accumulates on the top of the filter plate 5, the terminal controls the drive motor 401 to work. The output end of the drive motor 401 rotates to drive the threaded rod 402 to rotate. The threaded rod 402 rotates to drive the first moving rod 403 to move toward the end close to the water inlet 2. The movement of the first moving rod 403 drives the scraper 404 to move. The scraper 404 moves and drives the debris on the top of the filter plate 5 to move toward the end close to the blocking plate 410.

[0038] Then, the first moving rod 403 moves and drives the squeezing block 405 to move at the same time. When the squeezing block 405 moves and contacts one end of the moving block 406, the squeezing block 405 continues to move and squeezes the moving block 406 to move downward. The movement of the moving block 406 drives the rack 407 to move. The movement of the rack 407 drives the spur gear 408 to rotate clockwise. The spring 4074 is squeezed by force, and the spur gear 408 rotates to drive the rotating rod 409 to rotate. The rotation of the rotating rod 409 drives the blocking plate 410 to rotate. At this time, one end of the processing device body 1 is opened, and the debris pushed by the scraper 404 is discharged through the opened blocking plate 410. After cleaning is completed, the output end of the driving motor 401 rotates in the opposite direction and drives the scraper 404 to reset and move through the mechanical transmission. The spring 4074 returns to its original state and drives the blocking plate 410 to reset and rotate through the mechanical transmission. Then, one end of the processing device body 1 is closed.

[0039] Finally, the rainwater entering the main body 1 of the treatment device is filtered by the filter plate 5, and the debris is filtered to the top of the filter plate 5. The scraper 404 that moves horizontally is used to push the debris accumulated on the top of the filter plate 5, thereby ensuring the patency of the filter holes of the filter plate 5, thereby ensuring the filtering effect of the filter plate 5. Working through the same power source, the blocking plate 410 is driven to rotate clockwise, and the debris is discharged through the opening of the blocking plate 410, further ensuring the fluidity of the filter plate 5, while also ensuring the cleanliness of the top of the filter plate 5, reducing the load on the filter plate 5, and increasing the service life of the filter plate 5.
