Description

Technical Field

[0001] The utility model relates to the field of pipeline blockage removal, in particular to an internal cleaning device for municipal sewage pipelines. Background Technique

[0002] The blockage of municipal sewage pipelines may cause the following hazards:

[0003] 1. The blocked sewage pipeline will cause the wastewater to be unable to be discharged normally, which may cause sewage overflow, water accumulation and environmental pollution, affecting the surrounding soil and water quality;

[0004] 2. The blocked sewage pipeline may cause the sewage to flow back or overflow to the surrounding areas, increasing the risk of transmission of bacteria, viruses and parasites, and posing a threat to public health;

[0005] 3. The blockage may cause the internal pressure of the sewage pipeline to increase, resulting in pipeline rupture, leakage and facility damage, and increasing the maintenance cost of the drainage system;

[0006] 4. The blocked sewage pipeline will cause the sewage to stagnate, generating foul odors and affecting the living quality of the surrounding residents.

[0007] After retrieval, the patent publication number is CN214344742U, which discloses an anti-blocking and dredging device for municipal sewage discharge pipelines, relating to the field of municipal sewage discharge, including a drainage pipeline for sewage discharge; a connecting pipeline, the two ends of which are respectively flange-connected to the drainage pipeline; a sewage discharge pipeline, communicated with the bottom of the connecting pipeline for discharging sludge; a collection box, communicated with the bottom of the sewage discharge pipeline for collecting sludge; and a filter screen, arranged on the inner wall of the connecting pipeline for screening sludge; wherein, the filter screen is located downstream of the communication port of the sewage discharge pipeline and the connecting pipeline; the filter screen is inclined in the connecting pipeline, and half of the filter screen is inclined towards the side of the communication port of the sewage discharge pipeline and the connecting pipeline; the included angle between the filter screen and the axis of the connecting pipeline is between 30 degrees and 45 degrees. This application reduces the phenomenon of blockage in municipal sewage discharge pipelines.

[0008] In the existing technology, although a certain pipeline blockage removal effect can be achieved during use, the defect is that the blockage removal treatment of the existing pipeline blockage removal device is relatively cumbersome, resulting in a long working time and being unable to perform rapid blockage removal in case of emergency, leading to the problem of a long processing operation cycle. In view of this, we have proposed an internal cleaning device for municipal sewage pipelines to solve the above problems. Utility Model Content

[0009] The purpose of the present utility model is to propose an internal cleaning device for municipal sewage pipelines aiming at the problems in the background technique.

[0010] Technical solution of the utility model: A municipal sewage pipeline internal cleaning device, including a box body, a spiral column, a negative pressure machine and an installation groove. Elastic element - equipped rollers are arranged on the outer wall of the box body in an annular array distribution. A negative pressure machine is arranged in the middle of the box body. Installation plates are fixed on both sides inside the box body. Rotating frames are rotatably installed on both sides of the installation plates. A spiral column with a spiral design is arranged on the outside of the rotating frames;

[0011] When this device is in use, first place the box body into the pipeline of the corresponding size. Under the action of the spring, the rollers are in contact with the inner wall of the pipeline. The box body can move inside the pipeline. When moving along the pipeline, Motor 1 drives the spiral column to rotate. When the spiral column encounters blockage by small particulate matter enriched inside the pipeline, it will continuously scrape the surface of the blockage. After scraping, the objects will move towards the inside of the box body under the drive of the negative pressure machine and be discharged from the other side. Thus, the box body moves inside the pipeline to achieve the effect of dredging the enriched debris. It should be noted that this device is suitable for straight pipelines and pipelines with small - angle bends, and is not convenient to use for straight pipelines.

[0012] Preferably, a guide rail is fixed on the outer wall of the box body, and an installation groove fixed by screws is arranged inside the guide rail.

[0013] Preferably, a spring is arranged inside the installation groove. The lower end of the spring is fixedly connected to the outer wall of the box body, and the other end of the spring is fixed to a movable installation frame. The roller is rotatably installed inside the installation frame.

[0014] Preferably, a Motor 2 is fixed on the outer wall of one side of the installation frame, and the output shaft of Motor 2 is fixedly connected to the rotation center of one side of the roller.

[0015] Preferably, a Motor 1 is fixed on the outer wall of one side of the installation plate, and Motor 1 is fixedly connected to the rotation center of one side of the rotating frame.

[0016] Preferably, the box body is in a cylindrical design, the rotating frame is in a cross - shaped design, and one end of the spiral column exceeds the edge part of one side of the box body.

[0017] Compared with the prior art, the advantages of the utility model are as follows:

[0018] First, the utility model can use Motor 1 to drive the spiral column to continuously scrape the surface of the silt enriched inside the pipeline. The continuously scraped materials will fall into the pipeline through the box body, and then the blockage can be cleared by using water.

[0019] Second, based on the first beneficial effect, this device uses the spring and the installation frame to enable the box body to adapt to pipelines of different sizes, ensuring that Motor 1 drives the rollers to drive the device to move inside the pipeline.

[0020] Of course, it is not necessary for any product implementing the present utility model to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS
