A high-pressure hydrodynamic pipe inner wall cleaning crusher

Abstract

The present invention relates to the technical field of pipeline dredging. Although the existing municipal pipeline internal dredging devices can effectively dredge the inside of the pipeline, they cannot adjust the entire device according to the actual size of the pipeline. To solve the above technical problems, the technical solution provided by the present invention is a high-pressure water-powered pipeline inner wall cleaning crusher, which includes a power tooth shaft, a reducer housing, and an internal spline tooth disc arranged inside the reducer housing. The reducer housing and the internal spline tooth disc are coaxially arranged. A planetary gear set is arranged inside the internal spline tooth disc. The planetary gear set is composed of a connecting gland and a gear box. The outer edge of the connecting gland is fixedly connected to the edge of the port of the reducer housing. Different-width longitudinal guide plates and different-diameter and -type cutter heads can be selected for installation according to the diameter of the pipeline. The power tooth shaft is driven by high-pressure water to rotate at high speed, and then the speed is reduced by the planetary gear reduction device to increase the torque. The transmission shaft has a large torque and is suitable for dealing with hard pipe wall attachments.

Description

Technical Field

[0001] The present invention relates to the technical field of pipeline dredging, and specifically refers to a high-pressure hydrodynamic pipeline inner wall cleaning crusher. Background Art

[0002] Municipal drainage pipes refer to the rainwater and sewage pipes under municipal roads, that is, the so-called sewer pipes, which are usually called municipal drainage pipes in engineering. A drain pipe inner wall cleaner is a device for cleaning the residues attached to the inner wall of the drain pipe. In people's daily life, a large amount of garbage and sundries will be generated. Most of these garbage and sundries will be processed by the garbage treatment system, but there are some garbage and sundries that enter the sewer pipes, causing blockages. Traditional municipal sewer pipe dredging mostly uses manual digging or manual cooperation with sewage suction trucks. The working environment is harsh and the space is narrow. In case of emergencies, it is impossible to avoid in time, endangering the personal safety of construction workers.

[0003] There are also cleaning devices circulating on the market for cleaning the inside of municipal pipelines. For example, Chinese Utility Model Patent CN202122144316.6 discloses a dredging device inside a municipal drainage pipe, including a fixed shaft. There are two fixed shafts. A connecting shaft is rotatably connected between the two fixed shafts. A handle is fixedly sleeved on the surface of the connecting shaft. A spring soft shaft is wound around the surface of the connecting shaft. One end of the spring soft shaft is fixed to the surface of the connecting shaft. One end of the spring soft shaft is fixedly connected to a connecting plate. The present invention enables the staff to select and use the spring soft shaft or the fixing mechanism according to the actual situation to put the thorn rod into the drainage pipe for dredging.

[0004] Although the above-mentioned municipal pipeline inner wall dredging device can effectively dredge the inside of the pipeline, it cannot adjust the whole device according to the actual size of the pipeline, resulting in that the whole dredging device can only adapt to a single pipeline, having limitations.
