The sewage pretreatment tank 1 is semi-buried underground, and a motor 2 is fixedly connected to the outer wall of the upper end of the sewage pretreatment tank 1, and the motor 2 provides power for the sewage pretreatment tank 1. The operation of the motor 2 drives the bearing plate 9 to move, and the filter basket 5 is driven to rise by the movement of the bearing plate 9. The inner wall of the left end of the sewage pretreatment tank 1 is fixedly connected with the water inlet pipe 3, and the water inlet pipe 3 is used to transport the sewage into the sewage pretreatment tank 1. A sliding rod 11 is fixedly connected to the inner wall of the bottom end of the sewage pretreatment tank 1, and four sliding rods 11 are arranged. The four sliding rods 11 are fixed at the four corners in the sewage pretreatment tank 1, and the sliding rod 11 provides support for the sliding of the bearing plate 9. The outer wall of the sliding rod 11 is slidably connected with the bearing plate 9, and the setting of the bearing plate 9 is achieved by the rotation of the threaded rod 12 The filter basket 5 is movable by movement, and a through groove is arranged inside the upper end of the carrying plate 9. The carrying plate 9 provides support for the movement of the filter basket 5. A fixing block 10 is fixedly connected to the outer wall of the upper end of the carrying plate 9. The fixing block 10 is fixed to the outer wall of the upper end of the carrying plate 9. The fixing block 10 provides support and guidance for the movement of the filter basket 5. The fixing blocks 10 are symmetrically arranged. A through groove is arranged on the inner wall of the front end of the fixing block 10. The inner wall of the through groove of the fixing block 10 is slidably connected to the outer wall of the front end of the filter basket 5. A filter basket 5 is slidably connected to the outer wall of the upper end of the carrier plate 9. The filter basket 5 is used to filter the sewage transported by the water inlet pipe 3. A stopper 14 is elastically connected to the inner wall of the left end of the upper end of the carrier plate 9 through a spring 13. The outer wall of the stopper 14 contacts the outer wall of the left end of the filter basket 5 to limit the movement of the filter basket 5. The stopper 14 is pressed downward into the inner wall of the upper end of the carrier plate 9 to release the limit on the filter basket 5. The stopper 14 is arranged in a T shape, and the bottom width of the stopper 14 is greater than the upper width.

[0036] Furthermore, the outer wall of the stopper 14 is slidably connected to the inner wall on the left side of the upper end of the bearing plate 9, and the outer wall on the right end of the stopper 14 is slidably connected to the outer wall on the left end of the filter basket 5. One end of the spring 13 is fixedly connected to the inner wall on the left side of the upper end of the bearing plate 9, and the other end of the spring 13 is fixedly connected to the outer wall on the bottom end of the stopper 14. An outlet pipe 15 is fixedly connected to the inner wall on the rear end of the sewage pretreatment tank 1. The outlet pipe 15 transports the sewage after impurities are removed by the filter basket 5 to the buried sewage treatment tank body 4. The outer wall on the right end of the outlet pipe 15 is fixedly connected to the buried sewage treatment tank body 4. The water treatment tank body 4 is buried underground and performs deep treatment on the sewage treated by the sewage pretreatment tank 1. A threaded rod 12 is rotatably connected to the inner wall of the bottom end of the sewage pretreatment tank 1. The rotation of the threaded rod 12 drives the bearing plate 9 to move, thereby changing the position of the filter basket 5. The outer wall of the threaded rod 12 is threadedly connected to the inner wall of the upper right end of the bearing plate 9. The upper outer wall of the threaded rod 12 penetrates and is rotatably connected to the upper inner wall of the sewage pretreatment tank 1. The upper inner wall of the threaded rod 12 is fixedly connected to the output shaft of the motor 2, and a blocking component is fixedly connected to the inner wall of the left end of the sewage pretreatment tank 1.

[0037] Reference Figure 3 and Figure 4 The blocking assembly includes a slide bar 27, which provides support for the sliding of the baffle 6. During the upward movement of the supporting plate 9, the inner wall of the upper left side of the supporting plate 9 drives the baffle 6 to slide on the outer wall of the slide bar 27. The baffle 6 is elastically connected to the inner wall of the bottom end of the sewage pretreatment tank 1 through a spring 28. A filter hole is provided on the inner wall of the left end of the baffle 6. The baffle 6 moves as the supporting plate 9 moves upward. When the supporting plate 9 moves downward, the spring 28 drives the baffle 6 to move downward. The baffle 6 is arranged in an L shape. The outer wall of the baffle 6 is slidably connected to the inner wall of the left end of the sewage pretreatment tank 1. One end of the spring 28 is fixedly connected to the inner wall of the bottom end of the sewage pretreatment tank 1, and the other end of the spring 28 is fixedly connected to the outer wall of the lower right end of the baffle 6.

[0038] Working principle: sewage enters the sewage pretreatment tank 1 through the water inlet pipe 3, and the sewage filters the solid impurities through the filter basket 5. The filtered sewage enters the buried sewage treatment tank body 4 through the outlet pipe 15 for deep treatment. The rotation of the motor 2 drives the supporting plate 9 to move upward, and the supporting plate 9 drives the filter basket 5 and the baffle 6 to move upward. When the filter basket 5 moves to the left end opening of the sewage pretreatment tank 1, the filter basket 5 can be moved outward to clean the impurities inside by pressing the stopper 14 downward into the upper end inner wall of the supporting plate 9. During the upward movement of the supporting plate 9, the baffle 6 is driven to move upward to block the water inlet pipe 3. The impurities in the sewage transported by the water inlet pipe 3 are temporarily blocked in the water inlet pipe 3. The sewage in the water inlet pipe 3 passes through the filter holes on the baffle 6, driving the supporting plate 9 to move downward back to its original position. The baffle 6 leaves the right end outer wall of the water inlet pipe 3 under the action of the spring 28, and the sewage can continue to pass through the filter basket 5 for filtering.
