Description

Technical Field

[0001] The utility model relates to the technical field of protection pipe sealing, in particular to a sealing device for a power protection pipe. Background Technique

[0002] Power protection pipes are mainly used to load communication cables or optical cables and are buried underground. Since the underground is humid and highly corrosive, power protection pipes are made of PVC resin as the main raw material and various stabilizers are added to form various specifications of rigid polyvinyl chloride pipes, which have the characteristics of corrosion resistance, high temperature resistance, light weight, low project cost, and long service life.

[0003] In actual situations, since both ends of the power protection pipe are open, after the cable passes through the power protection pipe, workers need to use bricks, stones or colloidal substances for sealing to prevent other organisms or impurities from entering the power protection pipe. Therefore, a sealing device for a power protection pipe is needed.

[0004] The existing sealing devices for power protection pipes have certain drawbacks when in use. When the existing sealing devices for power protection pipes are in use, they usually directly use stones or other hard objects to seal the power protection pipe, which is likely to damage the power protection pipe, and the stones or other hard objects are likely to fall off and separate from the power protection pipe during the use process. Therefore, they cannot meet people's needs. Content of the Utility Model
