[0039] Specifically, the driving member 31 includes a fixing portion 311 and a driving portion 312. The fixing portion 311 is rotatably connected to the inside of the box body 10, and its relative position with the box body 10 remains unchanged. For example, the fixing portion 311 can be rotatably connected to the inner wall surface of the box body 10; for another example, a support member 40 is provided in the box body 10, and the fixing portion 311 is rotatably connected to the support member 40; in addition, a mounting seat can be provided in the box body 10, the mounting seat has a first connecting hole, and the fixing portion 311 has a second connecting hole. Pins are respectively inserted into the first connecting hole and the second connecting hole to achieve relative fixation of the fixing portion 311 and the box body 10, thereby improving the connection stability.

[0040] The driving part 312 is telescopically connected to the fixed part 311; when the driving assembly 30 is running, the driving part 312 can be telescopically moved relative to the fixed part 311 to extend and retract the box body 10; when the driving part 312 extends out of the box body 10, the door body 20 can be driven to rotate relative to the box body 10 to open the water storage chamber 11; when the driving part 312 is retracted into the box body 10, the door body 20 can be driven to rotate relative to the box body 10 to close the water storage chamber 11. And in some specific examples, the driving member 31 extends in the direction from the box body 10 to the door body 20, so that when the driving part 312 is extended relative to the fixed part 311, the driving part 312 can move from the box body 10 to the door body 20 to drive the door body 20 away from the box body 10, thereby opening the water storage chamber 11; when the driving part 312 is contracted relative to the fixed part 311, the driving part 312 can move from the door body 20 to the box body 10 to drive the door body 20 close to the box body 10, thereby closing the water storage chamber 11.

[0042] Among them, the adjusting rod 32 may include a hinge part 321 and an adjusting part 322; the hinge part 321 has a hinge hole, and the hinge hole is connected to the driving part 312 through a pin; specifically, the driving part 312 has a mounting hole, which may correspond to the hinge hole of the hinge part 321, and the pin may pass through the mounting hole and the hinge hole respectively, so as to rotatably connect the driving part 312 of the driving member 31 with the hinge part 321 of the adjusting rod 32, so as to facilitate the driving member 31 to drive the door body 20 to open and close.

[0043] In addition, the hinged portion 321 also has an adjustment hole, and the adjustment portion 322 is connected to the door body 20 and is threadedly matched with the adjustment hole to adjust the distance between the driving member 31 and the door body 20; specifically, a first thread is provided on the outer circumferential surface of the adjustment portion 322, and a second thread is provided in the adjustment hole. The adjustment portion 322 can be inserted into the adjustment hole, and the first thread of the adjustment portion 322 is threadedly matched with the second thread of the adjustment hole; when the adjustment portion 322 is driven to rotate relative to the hinged portion 321, the rotational motion of the adjustment portion 322 can be converted into the rotation of the adjustment portion 322. The axial movement of the hinged portion 321 can change the relative distance between the adjusting portion 322 and the hinged portion 321, thereby adjusting the spacing between the door body 20 and the driving member 31, so as to improve the sealing performance of the sewage tank 100 and ensure the opening and closing of the door body 20; of course, the hinged portion 321 can also be driven to rotate relative to the adjusting portion 322, thereby converting the rotational movement of the hinged portion 321 into the axial movement of the hinged portion 321, so as to change the relative distance between the adjusting portion 322 and the hinged portion 321, and then adjusting the spacing between the door body 20 and the driving member 31.

[0044] In addition, refer to Figures 1 to 5 In some specific examples, since the hinged portion 321 of the adjusting rod 32 is connected to the driving portion 312 of the driving member 31, the hinged portion 321 cannot be driven to rotate during adjustment, and the adjusting portion 322 needs to be driven to rotate; therefore, a door inspection port may be provided on the door body 20 to facilitate driving the adjusting portion 322 of the adjusting rod 32 to rotate; specifically, the door body 20 has an inner wall surface and an outer wall surface, the adjusting portion 322 of the adjusting rod 32 is penetrated through the inner wall surface of the door body 20, and the adjusting rod 32 further includes a first fixing portion 311 and a second fixing portion 311, which are respectively arranged on opposite sides of the inner wall surface of the door body 20 and are connected to the adjusting portion 322; the outer wall surface of the door body 20 has a door inspection port and a door sealing cover plate 2 1. The door sealing cover plate 21 can open and close the door inspection opening, which corresponds to the connection position between the adjustment portion 322 and the inner wall surface of the door body 20. In this way, when adjusting the adjustment portion 322, the door inspection opening on the outer wall surface of the door body 20 can be opened, and the connection between the first fixing portion 311 and the second fixing portion 311 and the adjustment portion 322 can be released, so that the adjustment portion 322 can be rotated relative to the hinge portion 321, thereby adjusting the distance between the driving member 31 and the door body 20. After the adjustment is completed, the adjustment portion 322 of the adjustment rod 32 is fixed to the inner wall surface of the door body 20 by the first fixing portion 311 and the second fixing portion 311, and then the door inspection opening is covered by the door sealing cover plate 21 to improve the connection stability between the adjustment portion 322 and the door body 20.
