Automatic flushing device for drainage pipeline

Abstract

The invention provides an automatic flushing device for a drainage pipeline, and relates to the technical field of drainage pipeline flushing equipment. The automatic flushing device based on the drainage pipeline comprises a frame body and hinges, the multiple hinges are fixedly connected to the upper portion of the interior of the frame body, a water blocking plate is rotationally connected to the interior of the frame body through the multiple hinges, a floating box is fixedly connected to the lower portion of one side of the water blocking plate, floating ball linkage mechanisms are arranged at the two ends of the upper portion of the frame body, bottom cavities are formed in the lower portions of the interiors of the two sides of the frame body correspondingly, and bottom limiting mechanisms are arranged in the two bottom cavities correspondingly. The water blocking plate is hinged to the upper portion of the frame body, the water blocking plate is provided with the floating box, the water blocking plate can stably rotate upwards through the impact force and buoyancy of water flow, it can be guaranteed that the water blocking plate is stabilized at the upper position in cooperation with a top limiting mechanism, and under the condition that the water flow is not obstructed, larger potential energy can be accumulated, the impact force during door closing is improved, the door closing stability is guaranteed, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of drainage pipeline flushing equipment, in particular to an automatic drainage pipeline flushing device. Background technique [0002] In the past, in the design and construction of urban underground drainage pipelines, in order to prevent urban areas from overflowing sewage and flooding and waterlogging due to insufficient pipeline capacity, the diameter of the pipeline was determined according to the instantaneous maximum amount of drainage that the pipeline needs to collect. Choose OK. In this way, when the design instantaneous maximum value of the flow rate does not appear, the water volume inside the pipeline will be relatively small, so that the water flow velocity in the pipeline will not reach the design value, and the sediment and pollutants in the sewage will settle in the pipeline, causing siltation . Especially in combined drainage pipes where rainwater and sewage are discharged together, due ...

AI Technical Summary

Problems solved by technology

This device does not need external power, and is used for the prevention and automatic cleaning of sediments in the drainage pipe. Although the above problems are solved, the strength and lubrication of the circumferential inclined surface are affected by the energy storage method of the door body using the circumferential inclined surface of the door shaft assembly. The requirements are very high, and the impact force at the end of the closing stroke is small. After installing the sealing edge, it is more difficult to close, and because there are too many impurities in the sewage, it is easy to block the door shaft assembly and cause the closure to be blocked. use of the device
