Sewage drainage pipe capable of automatically dredging during blockage

Abstract

The invention discloses a sewage drainage pipe capable of automatically dredging during blockage. The sewage drainage pipe comprises a main body, wherein a pipeline which penetrates through the main body up and down is arranged in the main body; a dredger which can rotate in the pipeline and move up and down is arranged in the pipeline; a water passing cavity which penetrates through the dredger up and down is formed in the dredger; a dredging mechanism is arranged in the dredger; the dredging mechanism is used for removing blockage in the pipeline; ejection mechanisms are arranged on the leftside and the right side of the pipeline; and each ejection mechanism comprises water inlet pipes which are symmetrically arranged on the left side and the right side of the pipeline in a communicating mode. According to the sewage drainage pipe, buoyancy force generated when water cannot pass through the sewage drainage pipe during blockage is used as a trigger mechanism, a floating plate is driven by water to ascend to release locking of an ejection spring, so that the spring provides power for the dredger; and meanwhile, a drill bit is formed on the lower side of the trigger under the driving of the floating plate, so that the blockage can be broken through more effectively, and meanwhile, after the blockage is removed, the dredger can return to an initial state under the action of water flow.

Description

technical field [0001] The invention relates to the field of sewage drainage pipes, in particular to a sewage drainage pipe which can be automatically dredged when blocked. Background technique [0002] In the process of our daily life, once some fixed substances in the water are easy to accumulate on the pipes when the sewage is discharged, our sewage drains will be blocked after a long time, and once the drains are blocked, it will be very troublesome Difficult to clean. Ordinary cleaning methods require a lot of time and material resources. It is even necessary to disassemble the pipe to remove the blockage to solve the problem of pipe blockage. Sometimes the blockage cannot be solved by ordinary people and can only be solved by professionals. , the present invention sets forth, can solve the above-mentioned problems. Contents of the invention [0003] In order to solve the above problems, this example designs a sewage drainage pipe that can be automatically cleared wh...
