Description

Technical Field

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. They are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Various pipes are often laid in water conservancy projects to meet people's needs. These pipes are mostly laid underground. During use, mud and sand often stick to the pipe walls or solid residue condenses and accumulates. If these debris are not cleaned up, the pipes will be blocked. Therefore, these pipes need to be cleaned. Pipes with larger diameters can be cleaned by manually climbing into the pipes, but it is more inconvenient to clean some pipes with smaller diameters.

[0003] In this regard, according to the search report of the novelty search agency, announcement number CN213162288U discloses a pipe cleaning device for water conservancy projects, including a cleaning mechanism and a walking mechanism. The lengths of the first telescopic rod and the second telescopic rod are adjusted according to the diameter of the pipe. The brush plate drives the bristles to be squeezed tightly against the inner wall of the pipe under the action of the first spring, which is beneficial to cleaning the inner wall of the pipe. The motor is started, and the motor drives the first telescopic rod to rotate through the motor shaft. The first telescopic rod drives the bristles to rotate and clean the inner wall of the pipe through the brush plate. The traction mechanism is started, and the traction mechanism drives the walking mechanism to move through the traction rope, pull ring and chassis to move the device. The second spring has a certain shock-absorbing effect, which can maintain the stability of the device and can adapt to the complex internal environment of the pipeline. It has the advantages of low labor intensity, high efficiency and a wide range of applications.

[0004] The above technology discloses a pipe cleaning device for water conservancy projects, which realizes the movement of the device inside the water conservancy project pipe by a provided walking mechanism, and realizes the brushing and cleaning of the inner wall of the water conservancy project pipe by the rotation of the provided brush plate. However, there are the following deficiencies when used: 1. Only by brushing the inner wall of the water conservancy project pipe, it is not possible to effectively clean the solid impurities that are condensed and blocked inside, and the cleaning effect is not ideal; 2. The impurities cleaned by brushing are still inside the pipe and need to be cleaned and removed separately later, and the impurities cannot be automatically removed during cleaning; improvement is needed. In view of this, the present application proposes a pipe cleaning device for water conservancy projects to solve the above problems. Utility Model Content
