[0035] A screw sleeve 11 is sleeved on the sewage pipe 9, the inner end top surface of the screw sleeve 11 abuts against the annular protrusion 9, the inner wall of the screw sleeve 11 is screwed with the external threads, and the middle part of the sewage pipe 9 is limited on the sewage outlet 4.

[0036] In the utility model, the sewage outlet is two, the two sewage outlets are arranged at intervals, the sewage pump is also two, and the sewage outlet of each sewage pump is connected with a sewage outlet through a sewage pipe. Among them, the two sewage pumps can be switched to use, can work simultaneously when the flow is large, also can work when one of the sewage pumps is overhauled, and the other sewage pump works, and the actual situation is selected.

[0037] In this embodiment, the box is a cuboid structure, and the sewage pump is placed in the chamber, which can store more sewage and reduce the start-stop frequency of the sewage pump. The chamber is also provided with a liquid level sensor 12, which is electrically connected with the sewage pump. In this embodiment, there are two liquid level sensors, one is arranged near the top of the chamber, and the other is arranged near the bottom of the chamber. When the upper liquid level sensor detects the water level, one sewage pump works. If the lower liquid level sensor does not detect the liquid level to this position, the sewage pump will continue to work. If the lower liquid level sensor detects the liquid level to this position, the sewage pump will stop working. If one sewage pump works for a period of time, for example, 30s or 60s, and the upper liquid level sensor can still detect the liquid level, it means that the water inflow may be greater than the water outflow, at this time, the other sewage pump is started, and the two sewage pumps work together to quickly lower the liquid level in the chamber until the lower liquid level sensor detects the liquid level, at this time, the two sewage pumps stop working and wait for the next detection signal from the corresponding liquid level sensor.
