Dredging device for urban sewer

Abstract

The invention discloses a dredging device for an urban sewer. The dredging device for the urban sewer comprises a mounting block, wherein a rope is fixedly arranged on the upper end surface of the mounting block, the mounting block is internally provided with a telescopic fixing device, the telescopic fixing device internally includes left and right symmetrical arc-shaped butting blocks, a power supply device is arranged on the lower side of the telescopic fixing device, and the power supply device internally includes a power motor. The dredging device is small in size, can be directly placedin the sewer, and is suitable for the use of sewers with different inner diameter and depth ranges. In the process of dredging, clogged debris and adherent sludge in the sewer are crushed by a crushing device, the dredging speed is high, and water sources are saved. The solid debris after being crushed is filtered and collected by a filter screen, and the dredging device is highly automatic.

Description

technical field [0001] The invention relates to the technical field of sewer treatment, in particular to an urban sewer dredging device. Background technique [0002] The sewer is a kind of urban public facility, which can be used to discharge sewage and rainwater. However, the blown domestic garbage or the sludge deposited during the circulation of sewage will easily block the sewer. Usually, only high-pressure water is used to clean the sewer. If the dredging method is not thorough, the high-pressure water will wash the garbage or silt in the pipeline to the next pipeline or the turning point of the pipeline. If the solid garbage is not cleared, it will cause the pipeline to be blocked again, or the downstream pipeline to be blocked. Secondly, the blockage is serious Or when the silt adheres heavily to the sewer, a large amount of high-pressure water is required to flush it, which wastes water resources and takes a long time. In addition, when the high-pressure water flush...

[0002] The sewer is a kind of urban public facility, which can be used to discharge sewage and rainwater. However, the blown domestic garbage or the sludge deposited during the circulation of sewage will easily block the sewer. Usually, only high-pressure water is used to clean the sewer. If the dredging method is not thorough, the high-pressure water will wash the garbage or silt in the pipeline to the next pipeline or the turning point of the pipeline. If the solid garbage is not cleared, it will cause the pipeline to be blocked again, or the downstream pipeline to be blocked. Secondly, the blockage is serious Or when the silt adheres heavily to the sewer, a large amount of high-pressure water is required to flush it, which wastes water resources and takes a long time. In addition, when the high-pressure water flushing still cannot dredge the pipeline, it is necessary to manually go down to the pipeline to remove the debris, but Since the sewer pipe contains a lot of harmful gases, it is very harmful to the health of the staff and can easily cause them to suffocate, so the safety of manual dredging is low.
