Description

Technical Field

[0001] The present invention relates to the technical field of water supply and drainage, and particularly to an anti-blocking device for water supply and drainage of building mechanical and electrical equipment. Background Art

[0002] As an important part of building construction projects, the installation of mechanical and electrical equipment plays an increasingly important role. Under the environment of intelligent buildings and the concept of energy conservation and environmental protection, higher requirements are put forward for the installation of mechanical and electrical equipment. Nowadays, drainage equipment is often used in the process of building construction. The water supply and drainage equipment includes pipelines, water pumps and some connecting devices. However, limited by factors such as the construction site, water source and impurities in the water, there are some problems in the process of water supply and drainage of mechanical and electrical equipment, which increases the difficulty of building construction.

[0003] When there is accumulation of impurities and silt inside the pipeline, it often coagulates into blocks, and it cannot be washed away by water flow alone. Therefore, it is necessary to disconnect the pipeline in a specific section and then use corresponding tools to peel off the coagulated silt for cleaning. Most of the existing connection mechanisms between water pumps and pipelines are fixed structures, and the connection is locked by clamps, bolts and wires, and the pipeline is also fixed. Therefore, it is difficult to disconnect the pipeline, disassemble the pipeline for cleaning and then reinstall it again. The cleaning process is cumbersome, time-consuming and laborious.

[0004] Therefore, this application document provides an anti-blocking device for water supply and drainage of building mechanical and electrical equipment. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-blocking device for water supply and drainage of building mechanical and electrical equipment that is simple to operate, can effectively clean the silt in the pipeline and prevent blockage.

Then, reset the cleaning mechanism and reserve a certain length of traction rope two. After that, bring the cleaning mechanism to the upper side of the sealing plate through the arc-shaped plate on the sliding plate one. Then install the sealing plate to seal. Finally, wash away the silt in the pipeline through the flushing of water flow to achieve the treatment of pipeline anti-blockage.
