AI Technical Summary
Existing sewage inspection wells are difficult to effectively drain sewage when outdoors in the absence of power, resulting in environmental pollution and high maintenance costs.
The sewage diversion device, which adopts the siphon principle, uses a suction pipe and a diversion pipe. The valve is opened and closed by pulling a rope. The device uses the suction pipe and the diversion pipe to divert sewage to other normal sewage inspection wells.
It enables sewage diversion through the siphon principle outdoors without relying on a power source, reducing maintenance costs and avoiding environmental pollution caused by sewage overflow.

TECHNICAL FIELD
[0001] The utility model relates to a drainage device, in particular to a sewage drainage device of a sewage inspection well. BACKGROUND
[0002] The sewage inspection well is a crucial component in the sewage pipeline system, mainly used for monitoring, inspection and maintenance of the operation of the sewage pipeline. With the acceleration of urbanization and the increasing demand for sewage treatment, the urban sewage pipe network construction is increasingly improved, and the design and installation of the sewage inspection well become more important. The sewage inspection well is usually arranged at the intersection, turning point, pipe inclination change and long pipe section of the sewage pipeline, as the main facility for periodic inspection and cleaning of the sewage pipeline. Because there are various garbage and sludge in the sewage, the pipe network is easily blocked, which causes the sewage to overflow from the sewage inspection well to the surrounding environment, causing environmental pollution events, so it is necessary to drain the sewage in the sewage inspection well to other places, not only to avoid environmental pollution, but also to facilitate the pipe network cleaning. The sewage drainage usually uses a sewage pump to pump the sewage in the well, but the use of the sewage pump must have a power supply around, and the position of the sewage inspection well is usually outdoor without power supply, so a mobile generator must be added to generate power for the sewage pump, but this will consume a lot of energy and increase the maintenance cost.
