Description

Technical Field

[0001] The present application relates to the technical field of water supply network maintenance, and in particular to a novel linear pipe dredge. Background Art

[0002] In the current urban water supply system, due to long-term use, dirt, sediment and even blockage are easily accumulated inside the pipes. In order to ensure normal water supply, regular cleaning of the pipes is crucial. In the existing water supply network maintenance work, high-pressure water jet cleaning, mechanical scraping and other methods are usually used to remove dirt in the pipes. Although these methods can alleviate the problem of pipe blockage to a certain extent, they still face many challenges in actual application. Several commonly used methods mainly include high-pressure water jet cleaning technology, which achieves the cleaning purpose by injecting high-pressure water into the pipe to impact the pipe wall; another common method is mechanical scraping, which is to use a tool with a brush or other scraping device to move along the pipe to remove accumulations. However, these two methods have their own limitations. For example, high-pressure water jet cleaning may cause damage to pipes made of more fragile materials, and mechanical scraping is often difficult to thoroughly clean the corners of pipes with certain complex structures.

[0003] Although the above two methods are widely used in pipeline cleaning, they still have problems such as low efficiency and limited scope of application. Especially when facing long straight pipelines, traditional equipment often finds it difficult to achieve efficient and fast dredging work, and there may also be safety risks.

[0004] To this end, this application proposes a novel linear pipeline dredge. Utility Model Content

The motor is started to drive the connecting shaft to rotate, and then the connecting shaft drives the outer shaft to rotate, and finally the outer shaft drives the inner shaft and the blade to rotate to clear obstacles. The powerful cutting force of the toothed knife can then be used to remove obstacles more quickly, solving the problems of low efficiency and even safety hazards existing in previous pipe clearing devices, and greatly improving the practicality of the device.
