Environment-friendly dredging device for municipal water conservancy project

Abstract

The invention relates to an environment-friendly dredging device for a municipal water conservancy project. The environment-friendly dredging device comprises a tensioning device, a conveying belt and a box body, wherein an underground pipeline is integrally assembled and formed by a plurality of groups of square culverts, a water inlet communicated with the underground pipeline is dug in the ground, the tensioning device comprises a winch and two groups of fixed pulleys, the conveying belt is laid in the underground pipeline, the two groups of fixed pulleys are respectively fixed on the ground and the inner bottom surface of the underground pipeline, a rope which is wound and rotated with the two groups of fixed pulleys is wound on the winch, and the lower end part of the rope is fixed with one end of the conveying belt in a bolting mode; the box body is located at one end of a water outlet, and a first roller and a second roller which are distributed up and down are rotationally connected to the end surface of one side, close to the underground pipeline, of the box body; and the conveying belt is wound and rotated with the first roller and is wound on the second roller, and a driving motor for driving the second roller to rotate is installed on the box body. According to the environment-friendly dredging device, operators are prevented from entering the underground pipeline, the overall dredging operation process is high in efficiency, and the operation safety of the operators is improved.

Description

technical field [0001] The present application relates to the field of environment-friendly dredging devices, in particular to an environment-friendly dredging device for municipal water conservancy projects. Background technique [0002] Municipal drainage pipes refer to the rainwater and sewage underground pipes under the municipal roads, commonly known as "sewage underground pipes", and are usually called municipal drainage underground pipes in engineering. According to the current situation of facilities under municipal roads in China, different pipelines are generally installed, such as underground pipelines for electricity, communications, gas, water supply, and drainage. The underground drainage pipes consider the rain and sewage diversion measures, that is, the rainwater is generally discharged into the river nearby, and the sewage is discharged into the sewage treatment plant, so the municipal drainage pipes include two kinds of underground pipes, rainwater and sewa...

AI Technical Summary

Problems solved by technology

[0003] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: for the relatively large underground pipelines, because the environment of the underground pipelines is relatively closed, and the silt layer settled inside the underground pipelines often hardens, so the underground pipelines During the dredging operation, it is mostly carried out by manual cleaning; during the cleaning operation, the cleaning personnel enter the interior of the underground pipeline from the position of the shaft, and enter the interior of the underground pipeline with hand-held cleaning tools to continuously scrape and rinse. The operating space is limited and the operating environment is harsh, so the overall efficiency of the manual cleaning operation is low, so there is room for improvement
