Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable protection pipe, in particular to a cable protection pipe with protection structure. BACKGROUND

[0002] The cable protection pipe is a pipe system for wrapping, supporting and protecting power cables or communication cables, mainly functions to prevent the cables from being damaged by external factors such as mechanical damage, environmental corrosion, animal gnawing, etc. during laying, operation and maintenance, and to provide fixation and path guidance for the cables.

[0003] The existing cable protection pipe is generally divided into single pipe and seven-hole plum blossom pipe. For thick cables, single protection pipe is usually used, while for multiple thin cables, they are placed in different pipes of the seven-hole plum blossom pipe. During the combined laying of thick and thin cables, multiple single protection pipes and multiple seven-hole plum blossom pipes are used in combination, and then the multiple protection pipes are sequentially sleeved in the multiple pipe supports for orderly placement. The pipe support is usually composed of two support plates which are connected to form a circular shape. After the seven-hole plum blossom pipe is placed in the pipe support, the contact area between the seven-hole plum blossom pipe and the inner wall of the pipe support is small, and the seven-hole plum blossom pipe is easy to shift, which may cause the twisting of the thin cables inside the pipe, and the excessive twisting may damage the cables. In addition, for different specifications of thin cables, the size of the selected seven-hole plum blossom pipe is also different. For the seven-hole plum blossom pipe with smaller hole diameter, it is more likely to shift inside the pipe support, which affects the protection effect of the cables. SUMMARY
