[0001] This invention relates to the field of power plant maintenance technology, specifically to a high-level pipeline cleaning device. Background Technology

[0002] Power plants are large in scale. In order to maintain the normal operation of the power plant, staff need to regularly maintain and clean the parts of the power plant in order to slow down the rate of corrosion of the parts and increase the service life of the power plant.

[0003] The existing power plant system is large. During maintenance and cleaning, when cleaning pipelines at high altitudes, it is difficult for manual labor to clean the pipelines due to the height obstacles. It is necessary to rely on lifting equipment and other auxiliary manual labor. The movement of the cleaning device by lifting equipment is less safe, and the lifting equipment itself is also large and inconvenient to move.

[0004] Based on this, the present invention designs a high-level pipeline cleaning device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a high-level pipeline cleaning device that can automatically prevent movement in the pipeline without the need for auxiliary lifting equipment, thereby saving manpower and improving safety during the cleaning process.

[0006] To achieve the above objectives, the present invention provides the following technical solution:
