An automatic flushing device for drainage pipes

Abstract

The invention discloses an automatic flushing device for drainage pipes, wherein the door body is arranged to be capable of reciprocating rotation between the position where the pipe is closed to intercept drainage and the position where the pipe is opened to discharge and flush; the door frame is used for installing a fixing device assembly, The door frame and the door body are hinged by a door shaft assembly; the door body closing control assembly is used to keep the door body in a closed state when accumulating water flow; the door body opening control assembly is used to keep the door body in an open state during flood discharge and scouring State; the sealing strip is arranged at the upstream edge of the door frame, and is used to block the gap between the door body and the door frame when the door body is closed. The door body of the present invention is kept in a fully open state by the limit of the door body opening control component during the flushing process. When the water level drops to a certain height, the door body closing control component releases the door body to complete a pipeline automatic flushing cycle process. The device does not need external power, and is used for the prevention and automatic cleaning of sediments in drainage pipes.

Description

technical field [0001] The invention relates to the technical field of drainage pipeline flushing, in particular to an automatic drainage pipeline flushing device. Background technique [0002] Traditional pipeline dredging technologies mainly include dredging dredging vehicle winch suction, high-pressure water flushing, etc. At present, dredging robots have also been developed and applied, but such dredging measures require a large investment, and are generally used when the pipeline network has already been blocked by sedimentation. , frequent dredging will greatly increase the workload and cost of long-term operation and maintenance of the pipeline network. The traditional pipeline dredging maintenance mode is faced with the occupation of pipeline drainage space when dredging is not timely. Deal with the problem. [0003] The automatic sediment removal technology of urban drainage system can better solve the above problems. Such technologies mainly include MSC-door flus...

AI Technical Summary

Problems solved by technology

The main control parts of the automatic flushing device based on hinge control are located below the liquid level of the drainage pipe. Due to the large amount of entangled garbage in the sewage of urban drainage systems in my country, the components of the device are eroded by sewage and entangled by garbage under long-term operation, and the operational reliability is greatly reduced.
