DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] For example, see Figure 1-3 , a device for removing floating objects on the surface of sewage in a sewage tank, comprising a device body 1 and a water pump 2, a pipe 3 is fixedly connected to the top of the water pump 2, a filter screen 4 is fixedly connected to the inside of the device body 1, and a cleaning component is arranged inside the device body 1;

[0022] The cleaning assembly includes an impeller 5 and a hydraulic tank 11. The water pump 2 is started to allow sewage to enter the pipe 3. After being filtered in the device body 1, the sewage enters the pipe 3, causing the impeller 5 rotatably connected to the pipe 3 to rotate under the action of the water flow. The front end of the impeller 5 is fixedly connected to a rotating shaft 6. The impeller 5 is rotatably connected to the pipe 3. The front end of the rotating shaft 6 is fixedly connected to a bevel gear 7. The rotation of the impeller 5 drives the rotating shaft 6 fixedly connected thereto to rotate. Since the bevel gear 7 is fixedly connected to the rotating shaft 6, the bevel gear 7 is driven by the rotating shaft 6 to rotate. The internal rotation of the device body 1 is connected to a rotating rod 9. The rotating rod 9 is The top is fixedly connected with bevel gear 28, which is located at the bottom of bevel gear 17. Bevel gear 28 is in meshing state with bevel gear 17. When bevel gear 17 rotates, bevel gear 28 meshing with bevel gear 17 drives rotating rod 9 fixedly connected with it to rotate under the action of bevel gear 17. A gear 10 is fixedly connected with the bottom of rotating rod 9. A piston on one side of hydraulic chamber 11 is slidably connected with toothed rod 12. Gear 10 is provided with half of teeth. Gear 10 is in meshing state with toothed rod 12 through the teeth. Rotating rod 9 rotates to make gear 10 fixedly connected with it rotate. The gear 10 is movable because half of the teeth are arranged on the gear 10. When the area with the teeth on the gear 10 rotates to the toothed rod 12, the toothed rod 12 meshing with the gear 10 moves. The piston on the other side of the hydraulic chamber 11 is slidably connected with a scraper plate 13. When the toothed rod 12 moves, it cooperates with the hydraulic chamber 11 slidably connected with the piston of the toothed rod 12. The toothed rod 12 moves to squeeze the liquid in the hydraulic chamber 11, so that the liquid in the hydraulic chamber 11 moves to one side of the scraper plate 13. Since the scraper plate 13 is slidably connected with the piston of the hydraulic chamber 11, the scraper plate 13 is squeezed by the liquid in the hydraulic chamber 11 and moves, and the side of the toothed rod 12 A spring 14 is fixedly connected and located inside the hydraulic bin 11. The spring 14 is fixedly connected to the inner wall of the hydraulic bin 11. The scraper plate 13 can move to scrape off the impurities filtered out of the filter screen 4. Similarly, when the area without teeth of the gear 10 rotates to the gear rod 12, the gear rod 12 loses the restriction of the gear 10, so that the gear rod 12 can be reset under the action of the spring 14 fixedly connected thereto. In conjunction with the hydraulic bin 11, the scraper plate 13 can be reset, so that the filter screen 4 can be scraped back and forth, reducing the possibility of floating impurities accumulating in one place, thereby improving the filtering effect of the device.

[0023] When in use, start the water pump 2 to allow sewage to enter the pipe 3. After being filtered in the device body 1, the sewage enters the pipe 3, causing the impeller 5 rotatably connected to the pipe 3 to rotate under the action of the water flow. The rotation of the impeller 5 drives the rotating shaft 6 fixedly connected to it to rotate. Since the bevel gear 17 is fixedly connected to the rotating shaft 6, the bevel gear 17 is driven by the rotating shaft 6 to rotate, and the bevel gear 28 meshing with the bevel gear 17 drives the rotating rod 9 fixedly connected to it to rotate under the action of the bevel gear 17. The rotation of the rotating rod 9 causes the gear 10 fixedly connected to it to rotate. Since the gear 10 is provided with half of the teeth, when the area with the teeth on the gear 10 rotates to the gear rod 12, the gear meshing with the gear 10 is rotated. The gear rod 12 moves, and cooperates with the hydraulic chamber 11 which is slidably connected to the piston of the gear rod 12. The gear rod 12 moves to squeeze the liquid in the hydraulic chamber 11, so that the liquid in the hydraulic chamber 11 moves to one side of the scraper plate 13. Since the scraper plate 13 is slidably connected to the piston of the hydraulic chamber 11, the scraper plate 13 is squeezed by the liquid in the hydraulic chamber 11 and moves. The movement of the scraper plate 13 can scrape off the impurities filtered out of the filter screen 4. Similarly, when the area without teeth of the gear 10 rotates to the gear rod 12, the gear rod 12 loses the restriction of the gear 10, so that the gear rod 12 can be reset under the action of the spring 14 fixedly connected thereto. In cooperation with the hydraulic chamber 11, the scraper plate 13 can be reset, and the filter screen 4 can be scraped back and forth.

[0024] For example 2, please refer to Figure 1-4 , on the basis of the first embodiment, an auxiliary striking component is provided inside the device body 1;

[0025] The auxiliary knocking component includes a conveyor belt 15. A rotating rod 16 is arranged inside the side of the conveyor belt 15 away from the rotating shaft 6. The rotating rod 16 is located at the bottom position of the rotating shaft 6. The rotating rod 16 is connected to the rotating shaft 6 through the conveyor belt 15. When the rotating shaft 6 rotates, the conveyor belt 15 arranged on the outside of the rotating shaft 6 is cooperated to make the rotating rod 16 connected to the rotating shaft 6 through the conveyor belt 15 rotate. The front end of the rotating rod 16 is fixedly connected to an elastic cam 17. The rotation of the rotating rod 16 drives the elastic cam 17 fixedly connected to it to rotate. The elastic cam 17 can knock the filter screen 4 above it when it rotates, thereby reducing the possibility of floating impurities blocking the openings of the filter screen 4, and further improving the filtering effect of the device.

[0026] When in use, on the basis of Example 1, when the rotating shaft 6 rotates, the conveyor belt 15 arranged on the outside of the rotating shaft 6 cooperates to make the rotating rod 16 connected to the rotating shaft 6 through the conveyor belt 15 rotate, and the rotation of the rotating rod 16 drives the elastic cam 17 fixedly connected to it to rotate, and the elastic cam 17 rotates to knock on the filter screen 4 above it.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
