[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-4 As shown, an assembled MPP cable protection pipe with moisture-proof function includes a first protection pipe 1 and a second protection pipe 2. Both ends of the first protection pipe 1 and the second protection pipe 2 are fixedly connected to flanges 3. One end of the first protection pipe 1 is provided with a sealing groove 5. One end of the second protection pipe 2 is fixedly connected to a sealing pipe 4, and the sealing pipe 4 and the sealing groove 5 are compatible. Bolts 6 are provided between the two flanges 3. Both the first protection pipe 1 and the second protection pipe 2 are provided with protective mechanisms 7 on their exteriors.

[0026] In this embodiment, the first protective pipe 1 and the second protective pipe 2 are conveniently spliced ​​together by the flange 3. The cooperation between the sealing pipe 4 and the sealing groove 5 plays a sealing role, preventing water or moisture from entering the connection and providing a moisture-proof function. The protective mechanism 7 effectively protects the cable protection pipe and extends its service life. The outer diameter of the sealing pipe 4 is 0.2-0.5mm smaller than the inner diameter of the sealing groove 5, and the contact surface is covered with a EPDM rubber sealing ring.

[0027] In one embodiment, such as Figure 1 and Figure 2 As shown, the protective mechanism 7 includes two protective tubes 71. One of the protective tubes 71 has a positioning groove 73 on its mounting surface, and the other protective tube 71 has a positioning member 72 fixedly connected to its mounting surface. The positioning member 72 and the positioning groove 73 are compatible with each other. The two protective tubes 71 can be easily installed on the outside of the cable protection pipe by the cooperation of the positioning member 72 and the positioning groove 73, which improves practicality.

[0028] In one embodiment, such as Figure 1 and Figure 3 As shown, a water tank 74 is provided inside the protective pipe 71. Connecting pipes 75 are fixedly connected to one side of the protective pipe 71 and both ends of the water tank 74. When the weather is cold, the low temperature can easily damage the cable. Hot water is introduced into the water tank 74 through the connecting pipe 75, and the hot water is discharged through another connecting pipe 75, forming a circulation. The hot water raises the temperature of the protective pipe 71, thereby raising the temperature inside the cable protection pipe. The hot water circulation to raise the temperature is an existing mature technology, which will not be described in detail here.

[0029] In one embodiment, such as Figure 4As shown, the protective tube 71 includes a base layer 711, with buffer grooves 712 evenly spaced in a ring inside the base layer 711. A wear-resistant layer 713 is attached to the outer side of the base layer 711, a waterproof layer 714 is attached to the inner side of the base layer 711, a cold-resistant layer 715 is attached to the inner side of the waterproof layer 714, and a shielding layer 716 is attached to the inner side of the cold-resistant layer 715. The shielding layer 716 is an aluminum-plastic composite film with a thickness of 0.1 mm and a shielding effectiveness >60 dB. The cold-resistant layer 715 is made of ITO nanoparticles, the waterproof layer 714 is an acrylic waterproof coating, and the wear-resistant layer 713 is made of phenolic resin. The cold-resistant layer 715 enables the protective tube 71 to have cold-resistant function, extending the service life of the cable in low-temperature environments. The waterproof layer 714 prevents water penetration into the cable protection tube, extending the service life of the protection tube. The buffer groove 712 gives the protective mechanism 7 a certain degree of buffering. The wear-resistant layer 713 improves the wear resistance of the protective mechanism 7.

[0030] The above embodiment discloses an assembled MPP cable protection pipe with moisture-proof function. The first protection pipe 1 and the second protection pipe 2 are easily spliced ​​together via flange 3. The cooperation between sealing pipe 4 and sealing groove 5 provides a seal, preventing water or moisture from entering the connection point, thus providing moisture-proof functionality. The cooperation between positioning element 72 and positioning groove 73 facilitates the installation of the two protection pipes 71 onto the outside of the cable protection pipe. When the weather is cold, low temperatures can easily damage the cable. Hot water is introduced into the water tank 74 through connecting pipe 75, and the hot water is discharged through another connecting pipe 75, forming a circulation. The hot water raises the temperature of the protection pipe 71, thereby raising the internal temperature of the cable protection pipe. The cold-resistant layer 715 gives the protection pipe 71 cold-resistant functionality, extending the cable's service life in low-temperature environments. The waterproof layer 714 prevents water penetration into the cable protection pipe, extending its service life. The buffer groove 712 provides a certain degree of cushioning for the protection mechanism 7, and the wear-resistant layer 713 improves the wear resistance of the protection mechanism 7.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
