A kind of sediment removal device in culvert pipe

Abstract

The invention discloses a removing device for silt in culvert pipes. The removing device comprises a submersible pump, a master controller, a control terminal and a plurality of dredging pipeline joints which are spliced together. The submersible pump is arranged at the bottom of a rainwater well. The master controller is mounted in a ground control cabinet adjacent to the first dredging pipelinejoint, and is connected with the control terminal through a network. The output end of the master controller is connected with the first dredging pipeline joint. The master controller controls the submersible pump and the dredging pipeline joints. The dredging pipeline joints comprise water inlet heads, water discharge heads, firefighting water tapes, water-discharge bifurcating members, electromagnetic water valves, nozzles, control boxes, pressure sensors, ultrasonic flow sensors and cable connectors. The removing device has the advantages that accumulation conditions of sediments in pipelines can be judged intelligently; when the sediments exceed to a certain extent, high-pressure jet water is sprayed segmentally and actively to fluidify the sediments, so that the sediments are drainedout under the action of gravity, the pipelines are dredged, and long-term smoothness of the drainage pipelines is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cleaning culvert pipes, in particular to a device for removing mud and sand in culvert pipes. Background technique [0002] The drainage pipe is responsible for drainage and sewage. After a period of operation, the drainage pipe will definitely have sedimentation and siltation, which will seriously cause blockage of the water passing section. If the silt is not cleared in time, the sewage will overflow. At the same time, organic deposits will also corrupt and produce a large amount of flammable toxic and harmful gases, causing potential safety hazards. [0003] The current pipeline desilting methods are: [0004] (1) Push rod and rotary rod dredging method: This method is the most commonly used dredging method, that is, manually push hard objects such as bamboo chips and steel bars into underground pipes, or use springs and soft shafts to rotate into the sewer under the action of the machine , with the ...

However, the cost of this method is high, and it is not easy to be widely used.

[0007] Moreover, the above three methods of dredging pipelines are dredging schemes implemented after the pipeline is blocked, which cannot guarantee that the water section of the pipeline will never be blocked, and are temporary emergency solutions.
