Sludge removing device for underground pipelines

Abstract

The invention provides a sludge removing device for underground pipelines. The sludge removing device comprises a supporting mechanism arranged on the ground of a vertical shaft, a sludge removing mechanism arranged on the supporting mechanism and used for removing sludge, a sealing module cooperating with the sludge removing mechanism, a propelling mechanism arranged on the supporting mechanism,a collecting mechanism arranged on the propelling mechanism and used for collecting sludge, a disassembling and assembling mechanism arranged on the supporting mechanism and used for cooperating withthe propelling mechanism, and a controlling mechanism arranged on the supporting mechanism and used for controlling the supporting mechanism, the sludge removing mechanism, the propelling mechanism, the collecting mechanism, the sealing module and the disassembling and assembling mechanism to cooperate. The sludge removing device can clean narrow underground pipelines efficiently without consumingmuch water; besides, the sealing module arranged on the upstream part can avoid the situation that due to continuous enrichment of upstream sewage, part of sludge cannot be thoroughly removed, and sludge can be thoroughly removed at a time.

Description

technical field [0001] The invention relates to the technical field of municipal dredging devices, in particular to an underground pipeline dredging device. Background technique [0002] Urban underground drainage pipes are an important system to prevent urban waterlogging and drainage. For many branch drainage systems, the diameter of air pipes is only 600mm and 800mm. Such a small pipeline dredging cannot be operated manually. The existing sedimentation sludge recovery device in the drainage pipeline is that the staff hold the suction hose nozzle connected to the recovery tank equipped with an air suction pump on the ground and enter the drainage pipeline to remove the sediment. The sludge is recovered from the suction hose nozzle to the recovery tank on the ground; because the working environment in the drainage pipe is poor and emits a strong smell, it is difficult to work for a long time and the work efficiency is low. In the knotted state, it is still difficult to suc...

Problems solved by technology

Such a small pipeline dredging cannot be operated manually. The existing sedimentation sludge recovery device in the drainage pipeline is that the staff holds the suction hose nozzle connected to the recovery tank equipped with an air suction pump on the ground and enters the drainage pipeline to remove the sediment. The sludge is recovered from the suction hose nozzle to the recovery tank on the ground; because the working environment in the drainage pipe is poor and emits a strong odor, it is difficult to work for a long time and the work efficiency is low. In the knot state, it is still difficult to suck and recover from the hose nozzle only by suction, and it is impossible to clean up all the settled sludge from the sludge in the drainage pipe

Although there is a desilting device currently being studied, it requires a large amount of water and is not thoroughly cleaned, and many people are required to coordinate operations during work, and because it is a mobile sewage operation, the upstream sewage will continue to flow here. Enrichment is carried out at places, which makes the work more difficult, so pipeline dredging has always been a difficult problem
