[0029] In this embodiment, a plurality of locking screws 10 are installed on one side of the fin fixing plate 9, and the locking screws 10 pass through the fin fixing plate 9 and are threadedly connected to the fixed shell 1. The aluminum heat sink fin 11 is fixedly installed in the middle of the two fin fixing plates 9. The fin fixing plate 9 is installed and fixed by the locking screws 10, and the fin fixing plate 9 plays the role of installing and fixing the aluminum heat sink fin 11.

[0030] In this embodiment, a cable insulation pipe structure 18 is provided for cable insulation. The cable insulation pipe structure 18 includes a ceramic insulation pipe 19, a polyurethane foam plastic pipe 20 and a thermally conductive copper pipe 21. The ceramic insulation pipe 19 is installed in the middle of two pipe fixing frames 16, the polyurethane foam plastic pipe 20 is installed inside the ceramic insulation pipe 19, and the thermally conductive copper pipe 21 is installed inside the polyurethane foam plastic pipe 20. The ceramic insulation pipe 19, the polyurethane foam plastic pipe 20 and the thermally conductive copper pipe 21 are located behind the thermally conductive copper ring 12, the polyurethane foam plastic pipe 20 is connected to the inside of the thermally conductive copper ring 12, the thermally conductive copper pipe 21 is fixedly connected to the thermally conductive copper ring 12, and the thermally conductive copper pipe 21 is installed in a spiral arrangement.

[0031] In this embodiment, the motor fixing ring 13 is located in front of the ceramic insulation tube 19 and the polyurethane foam plastic tube 20, the annular motor 14 and the air-blowing turbofan 15 are located in front of the pipeline fixing frame 16, and the air-blowing turbofan 15 blows air into the fixed shell 1.

[0032] In this embodiment, the ceramic insulation board 5 is located in front of the annular motor 14 and the air-blowing turbofan 15, the cable through-hole 7 is connected with the interior of the polyurethane foam plastic tube 20, and the insulation board air guide hole 8 is connected with the interior of the fixed shell 1, and the insulation board air guide hole 8 serves the effect of air intake.

[0033] In this embodiment, the screw mounting holes 6 penetrate the ceramic heat insulation board 5 , and a plurality of screw mounting holes 6 are arranged in a circular pattern around the center of the ceramic heat insulation board 5 , and the screw mounting holes 6 are used to pass the mounting screws.

[0034] In this embodiment, a fixing frame air guide hole 17 is opened inside the pipe fixing frame 16. The two pipe fixing frames 16 are symmetrically arranged and installed. The pipe fixing frames 16 are located in front of the aluminum heat dissipation fins 11. The fixing frame air guide holes 17 increase the air flow effect.

[0035] In this embodiment, the connecting plug plate 4 is inserted into the connecting card slot 2, and the outer shell cover 3 is fixedly connected to the fixed outer shell 1 through the connecting plug plate 4 and the connecting card slot 2. A plurality of hollow grooves are provided inside the fixed outer shell 1, and the fixed outer shell 1 increases the heat insulation effect through the hollow structure.

[0036] The heat-insulating protection device connected with cables for heat preservation and hot processing of parts, when in use, the fixed shell 1 and the shell cover 3 are the main shell parts, and the ceramic insulation board 5 is attached to the outside of the cable connection end, and is connected to the installation position through the screw installation hole 6, so as to realize the overall installation and fixation of the device. At the same time, the ceramic insulation board 5 plays a role in heat insulation at the installation position. After the device is installed and fixed, the cable passes through the heat-conducting copper ring 12, and then the cable enters the polyurethane foam plastic tube 20 in the fixed shell 1, and then passes through the cable through the cable through the center of the ceramic insulation board 5. The cable enters the installation position for use, and the polyurethane foam plastic tube 20, the ceramic insulation tube 19, the fixed shell 1 and the shell cover 3 play a role in heat insulation of the passing cable.

[0037] In order to better insulate, the fixed shell 1 and the shell cover 3 are the outermost shells. The inorganic fireproof board material of the fixed shell 1 and the shell cover 3 plays the role of outer insulation and flame retardancy. Then the cable passes through the polyurethane foam plastic tube 20 and the ceramic insulation tube 19. The ceramic insulation tube 19 is insulated based on the principle of low thermal conductivity. The polyurethane foam plastic tube 20 is further insulated by the material with good thermal insulation properties. At the same time, the ceramic insulation board 5 plays the role of insulation at the installation position. The composition of multiple layers of different materials forms a multi-layer insulation structure, which more effectively insulates the cable.

[0038] In order to dissipate heat, a heat-conducting copper tube 21 is sheathed inside the polyurethane foam plastic tube 20. The heat-conducting copper tube 21 is attached to the outside of the cable passing through. The heat-conducting copper tube 21 absorbs and transfers heat, so that the heat-conducting copper tube 21 transfers the heat to the heat-conducting copper ring 12, and the heat-conducting copper ring 12 transfers the heat to the aluminum heat dissipation fins 11. The heat is dissipated by the contact between the aluminum heat dissipation fins 11 and the air, so as to dissipate the heat entering the polyurethane foam plastic tube 20. While the cable is insulated with multiple layers, the heat is dissipated more thoroughly.

[0039] In order to dissipate the internal heat, the motor fixing ring 13 is installed in front of the heat-conducting copper tube 21 inside the polyurethane foam plastic tube 20. The annular motor 14 outside the heat-conducting copper tube 21 drives the air-blowing turbofan 15 to rotate after operation. The rotation of the air-blowing turbofan 15 draws air from the air guide hole 8 of the heat insulation board and blows it backward. The air is blown backward in the fixed outer shell 1 and the outer shell cover 3, which not only blows the heat in the fixed outer shell 1 and the outer shell cover 3 to the outside, but also blows toward the aluminum heat sink fins 11 when the air is discharged from the rear of the fixed outer shell 1, which cooperates with the aluminum heat sink fins 11 to dissipate heat and cool down. While exporting heat, it plays the role of heat dissipation and active heat dissipation, and more effectively insulates the cable.
