Description

Sewer backflow preventing structure

Technical Field

The utility model belongs to the technical field of drainage, and particularly relates to a backflow preventing structure of a sewer.

Background

A large number of shrimp larva culture ponds are built in the shrimp larva culture workshop, so that a sewer is needed to be built in the culture workshop, and culture water in the shrimp larva culture ponds can be discharged into the sewer by utilizing a transfer pipe through a siphon principle or other water pumping equipment. Therefore, the sewer is provided with a water inlet. When the water is discharged, one end of the transfer pipe is required to be placed in the water inlet, and the other end of the transfer pipe is connected to the shrimp larvae culture pond, so that culture water can be directly discharged into a sewer, and pollution caused by the fact that the culture water flows into a culture workshop is avoided. Therefore, a large amount of pollutants such as bacteria and sewage gas can be accumulated in the sewer in the use process, and the pollutants can flow back into a cultivation workshop through the water inlet, so that the cultivation environment is polluted. In addition, the transfer pipe often cannot be well fixed in the water inlet during drainage, so that the transfer pipe is easy to separate from the water inlet in the drainage process, and the aquaculture water flows into a workshop, so that inconvenience is caused to drainage. Therefore, the sewer backflow preventing structure can prevent pollutants in the sewer from flowing back into a workshop through the water inlet, and meanwhile the adapter tube can be conveniently and quickly fixed in the water inlet.
