Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Example 1:

Please refer to FIG. 1 , the present utility model provides a technical solution: a CPVC power cable protection pipe with hexagonal support ribs, including a pipe body 1, a hexagonal support rib 5 is installed in the pipe body 1, and the hexagonal support ribs 5 are connected to the pipe body. A filling layer 6 is filled between the inner walls of the hexagonal support rib 5, a cable duct 7 for installing cables is also provided in the middle of the hexagonal support rib 5, and a buffer layer 8 is provided between the cable duct 7 and the inner wall of the hexagonal support rib 5. The angular support ribs 5 are all over the inside of the pipe body 1, which provides a supporting force for the pipe body 1, improves the strength of the pipe body 1 itself, prevents the pipe 1 from being broken by external extrusion or collision and damages the cable, and has a good protection effect. The purpose of setting the layer 6 is to fill the voids inside the tube body 1 , and the buffer layer 8 has a certain function of shock absorption and energy absorption, which can further protect the cable.

Please refer to FIG. 1, wherein, preferably, the outer wall of the pipe body 1 is provided with a polyurethane heat-resistant coating 2, an anti-aging layer 3 and an anti-corrosion layer 4 in sequence, and the polyurethane heat-resistant coating 2, the anti-aging layer 3 and the anti-corrosion layer The arrangement of the layer 4 can improve the heat resistance, aging resistance and corrosion resistance of the pipe body 1 itself, and prolong the service life of the pipe body 1 itself.
