The device body includes two semicircular pipe sleeves, one end of the two semicircular pipe sleeves are rotatably connected, and the other end is detachably connected through the snap screws. The six ferrules are evenly connected to the outside of the device body through argon arc welding. The opening of the ferrule is an arc port. The inner diameter of the ferrule body is larger than the inner diameter of the arc port. A roller is fixedly clamped in each ferrule.

[0005] Furthermore, an insulating tape is wrapped around the outside of the protection device, and the insulating tape is made of polyvinyl chloride.

[0006] Furthermore, the device body is made of 40 flat steel.

[0007] Furthermore, the sleeve is made of stainless steel, and the roller is made of polyester.

[0008] Furthermore, the inner diameter of the device body is 140 mm and the outer diameter is 148 mm.

[0009] Furthermore, the inner diameter of the ferrule body is 20 mm, the outer diameter is 30 mm, the inner diameter of the arc port is 16 mm, and the diameter of the roller is 18 mm.

[0010] Furthermore, the snap screw includes a bolt and a nut, the bolt model is M8×1.0, and the nut model is M10×1.0.

[0011] The beneficial effects of the present invention are as follows: the present invention eliminates the hidden danger of scratching and damage during the laying of high-voltage cable crossing cable pipes, thereby ensuring personal and property safety; reducing manpower input and saving costs; being easy to operate and detachable and reusable; being simple to manufacture and having strong practicality.

[0015] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with embodiments:

[0017] like Figure 1-2 As shown, a cable laying pipe protection device includes a device body 1, a snap screw 2, six ferrules 3, and six rollers 4. The device body 1 includes two semicircular pipe sleeves, one end of the two semicircular pipe sleeves is rotatably connected, and the other end is detachably connected through the snap screw 2. The six ferrules 3 are evenly connected to the outside of the device body 1 through argon arc welding. The opening of the ferrule 3 is an arc port, and the inner diameter of the body of the ferrule 3 is larger than the inner diameter of the arc port. A roller 4 is fixedly clamped in each of the ferrules 3. The snap screw 2 is provided to ensure that the device is easy to disassemble and assemble. During the cable laying process, the roller 4 is used to slide on the pipe wall to reduce friction and eliminate the hidden danger of scratching and damage to the cable itself.

[0018] An insulating tape is wound around the outside of the protection device, and the insulating tape is made of polyvinyl chloride.

[0019] The device body 1 is made of 40 flat steel.

[0020] The ferrule 3 is made of stainless steel, and the roller 4 is made of polyester.

[0021] The inner diameter of the device body 1 is 140 mm, and the outer diameter is 148 mm.

[0022] The inner diameter of the ferrule 3 body is 20 mm, the outer diameter is 30 mm, the inner diameter of the arc port is 16 mm, and the diameter of the roller 4 is 18 mm.

[0023] The snap screw 2 includes a bolt and a nut, the bolt model is M8×1.0, and the nut model is M10×1.0.

[0024] The production principle and use method of the present invention are:

[0025] Phase 1: Check the construction drawings in the early stage of construction to confirm the designed diameter of high-voltage cables and protection pipes;

[0026] The second stage: According to the diameter of the high-voltage cable and the diameter of the protection tube, the appropriate profile is selected through calculation, and the processing drawing of the protection device is drawn using drawing software. The processing plant completes the processing according to the size of each component, and the components are welded and screwed together on site;

[0027] The third stage: According to the diameter of the high-voltage cable or the diameter of the protective tube on site, a protective device is installed approximately every 2 meters to protect the high-voltage cable; when the cable is about to be laid, the device is dismantled in advance, and the cable is wrapped with cotton cloth and finally laid in place, thus ensuring the quality of the project.

[0028] The above is an exemplary description of the present invention. Obviously, the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or they are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
