A kind of submerged storage flushing equipment for drainage network pipe and its application

Abstract

The invention relates to sunken type impoundment flushing equipment for a drainage network pipe and application of the sunken type impoundment flushing equipment. The drainage network pipe comprises a drainage pipeline, wherein the impoundment flushing equipment comprises a sunken impoundment flushing weir, a hydraulic cylinder, an electromagnetic valve, a hydraulic pump, a liquid indicator and an automatic control unit, wherein the sunken impoundment flushing weir is arranged in the drainage pipeline and can be raised up to lift the liquid level in the drainage pipeline to obtain flush water to flush the drainage pipeline; the hydraulic cylinder is connected with the sunken impoundment flushing weir and used for driving the sunken impoundment flushing weir to life up and down; the electromagnetic valve is connected with the hydraulic cylinder to control the motion state of the hydraulic cylinder; the hydraulic pump is connected with the electromagnetic valve and provides the hydraulic energy for the hydraulic cylinder through the electromagnetic valve; the liquid indicator is arranged inside the drainage pipeline and used for detecting the liquid level height in the drainage pipeline; the automatic control unit is respectively connected with the electromagnetic valve, the hydraulic pump and the liquid indicator, and used for controlling work of the electromagnetic valve and the hydraulic pump according to the liquid level in the drainage pipeline. Compared with the prior art, the sunken type impoundment flushing equipment disclosed by the invention has the advantages of a good cleaning effect and the like.

Description

technical field [0001] The invention relates to a flushing and dredging technology in the field of municipal drainage, in particular to a sinking storage and flushing equipment used for drainage network pipes and its application. Background technique [0002] After the sewage flows from the drainage branch pipe with a large slope into the main drainage pipe with a small slope and large diameter, the flow velocity decreases, and the sediment and suspended solids carried in the sewage are easily deposited, resulting in a reduced water cross section , the pipeline transport flow decreases. In addition, the pollutants accumulated in the pipeline are easy to produce toxic, harmful and corrosive gases, which will affect the environment, and the corrosive gases will cause corrosion to the drainage pipeline and affect the design service life of the drainage pipeline. If the pipeline silt is not cleaned in time, it will not only affect the health of residents and the normal operatio...

Problems solved by technology

The above-mentioned existing methods are basically designed for the dredging of small-diameter pipelines. Some techniques have high labor costs and potential safety hazards. Some techniques are not suitable for application in large-diameter pipelines, pipe channels, and box culverts. Caliber drainage pipes, pipes, and box culverts have limitations such as high operating costs, insufficient dredging capacity, secondary pollution, and inability to adapt to complex terrain conditions.
