Sewer desilting device for municipal engineering

Abstract

The invention discloses a sewer desilting device for municipal engineering. The sewer desilting device can be put into a sewer for expansion to increase the cleaning range. By adopting the device, thecleaning area can be increased without the limitation of the diameter of a pipe of an inspection well, and the efficiency of desilting the sewer is effectively improved. The device is characterized in that a fixing sleeve is placed at the middle of a connecting plate, the connecting plate is of a circular platy structure and is made of rigid materials, one end of a transmission rod is placed in the fixing sleeve and provided with a sliding groove, one end of each scraping plate is placed outside the fixing sleeve, the other ends of the scraping plates are connected through a fixing ring, andeach scraping plate is of an arc-shaped platy structure and is made of a steel sheet; one side of each scraping plate is connected with the connecting plate, the diameter of a connecting ring is greater than that of the connecting plate, multiple barbs are arranged on the surfaces of the scraping plates and made of tungsten steel, the transmission rod is sleeved with the connecting ring, one end of each bent plate is placed on the connecting ring through a fixing lug, and the other end of each bent plate is placed on the fixing ring through a fixing lug.

Description

technical field [0001] The invention relates to a sewer dredging device for municipal engineering, relates to a device for dredging sewers used in municipal engineering, and belongs to the field of municipal engineering. In particular, it relates to a dredging device that can be put into the sewer to expand and increase the cleaning range. Background technique [0002] At present, in municipal engineering, sewers play an important role as urban living facilities for collecting and discharging urban domestic wastewater and industrial wastewater generated by industrial production. There are often problems of blockage caused by sludge deposition in the sewers, hindering the drainage system. The normal operation of the sewers usually requires regular dredging of the sewers. The dredging of the sewers is carried out at the manhole. Usually, the manhole and the drainage pipe are in a vertical state, and the diameter of the manhole pipe is smaller than that of the drainage pipe. A...

Problems solved by technology

[0002] At present, in municipal engineering, the sewer plays an important role as an urban living facility for collecting and discharging urban domestic wastewater and industrial wastewater generated in industrial production. Blockage problems often occur in the sewer due to silt deposition, hindering the drainage system The normal operation of the sewer usually requires regular desilting work on the sewer. The desilting work of the sewer is carried out at the inspection well. Usually the inspection well and the drainage pipe are in a vertical state, and the diameter of the inspection well pipe is smaller than that of the drainage pipe. The sludge at the connection position is cleaned. At the same time, the operator stirs in the pipeline through the cleaning tool on the ground, but the diameter of the manhole pipeline limits the size of the tool, and the cleaning range is limited. Publication No. CN104975651A discloses a sewer dredging device, including a motor, a motor drive Matched reduction box and a sludge loosening device fixed on the output shaft of the reduction box of the reduction box, the rotation range of the sludge loosening device of this device is fixed, and the cleaning range from the bottom to the drainage pipe is small, the efficiency is low, and the use effect is not good
