[0023] In order to enable the scraper 8 to move up and down, thereby scraping off the debris on the left side of the filter screen 5, the lifting mechanism 10 includes two screws 101. The upper end surfaces of the two screws 101 are respectively bearing-connected to the left and right sides of the top surface of the inner wall of the connecting pipe 9, and the lower end surfaces of the two screws 101 are bearing-connected to the top surface of the valve body 1. The upper ends of the surfaces of the two screws 101 are commonly threadedly sleeved with a connecting block 102, and the top surface of the connecting rod 7 is fixedly connected to the middle of the bottom surface of the connecting block 102.

[0024] In order to drive the two screw rods 101 to rotate synchronously, a through hole 11 is opened in the middle of the top surface of the connecting tube 9, and a connecting shaft 103 is sleeved on a bearing in the through hole 11. The lower end of the surface of the connecting shaft 103 penetrates into the inner side of the connecting tube 9, and a driving gear 104 is fixedly connected to the lower end surface of the connecting shaft 103. The upper ends of the surfaces of the two screw rods 101 are fixedly sleeved with driven gears 105, and the two driven gears 105 are meshed with the driving gear 104. A motor 106 is fixedly connected to the middle of the top surface of the connecting tube 9, and the shaft of the motor 106 is fixedly connected to the upper end surface of the connecting shaft 103.

[0025] In order to facilitate the removal of debris stored in the inner cavity of the connection box 2, a cleaning opening 12 is opened in the middle of the bottom of the connection box 2, and the cleaning opening 12 is arranged on the left side of the filter 5. A fixing block 13 is inserted into the cleaning opening 12, and a sealing sleeve 14 is fixedly sleeved on the upper end of the surface of the fixing block 13. The bottom of the fixing block 13 passes through to the outside of the bottom of the connection box 2. Threaded holes 15 are opened on the bottom surface of the connection box 2 and on the left and right sides of the cleaning opening 12. Bolts 16 are threadedly sleeved on the left and right sides of the bottom of the fixing block 13, and the upper ends of the two bolts 16 are respectively threadedly connected in the adjacent threaded holes 15.

[0026] In order to prevent the sewage in the connection box 2 from entering the connection pipe 9 through the movable hole 6 , a sealing rubber sleeve 17 is fixedly sleeved in the movable hole 6 , and the lower end of the surface of the connecting rod 7 is movably sleeved in the inner cavity of the sealing rubber sleeve 17 .

[0027] In order to conveniently connect the valve body 1 and the water inlet pipe 4 to an external pipeline, a first flange 18 is fixedly connected to the right end of the valve body 1 , and a second flange 19 is fixedly connected to the left end of the water inlet pipe 4 .

[0028] In order to allow the water in the connection box 2 to flow into the valve body 1 from the left side and be discharged through the right end of the valve body 1, the left end of the valve body 1 is the water inlet end, and the right end of the valve body 1 is the water outlet end.

[0029] Working principle: When the utility model is used, the sewage first enters the connection box 2 through the water inlet pipe 4, and then the impurities in the sewage are filtered through the filter screen 5. The filtered sewage enters the valve body 1 through the outlet pipe 3. Some of the filtered impurities will adhere to the left side of the filter screen 5. The motor 106 is started, and the motor 106 drives the connecting shaft 103 to rotate. The connecting shaft 103 drives the driving gear 104 to rotate. The driving gear 104 drives the two driven gears 105 to rotate. The driven gear 105 drives the screw rod 101 to rotate. The rotation of the screw rod 101 causes the connecting block 102 to descend, and the connecting block 102 drives the connecting shaft 103 to rotate. The connecting rod 7 descends, and the connecting rod 7 drives the scraper 8 to descend. Since the right side of the scraper 8 fits with the left side of the filter screen 5, the scraper 8 will scrape the left side of the filter screen 5 when it descends, and scrape off the debris attached to the left side of the filter screen 5, so as to clean the filter screen 5 and prevent the filter screen 5 from being blocked, thereby ensuring the normal operation of the valve body 1, twisting the bolt 16 so that the upper end of it is moved out of the threaded hole 15, thereby releasing the fixation of the fixing block 13, and then pulling the fixing block 13 down and pulling it out of the cleaning opening 12, so that the impurities in the connection box 2 can be taken out through the cleaning opening 12, which is convenient for cleaning the impurities stored in the connection box 2.

[0030] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
