[0034] This solution has the following working process: when the heating pipe body 102 is protected from freezing, the heating pipe 600 is started, and the heating pipe 600 heats the air between the first outer cover 100, the second outer cover 101 and the heating pipe body 102. The heated air provides heat to the outer wall of the heating pipe body 102, so that the outer wall of the heating pipe is in a heating state. The heated air can pass through the vent 501, so that the contact surface between the fixing frame 500 and the heating pipe body 102 is also in a heating state. After heating for a period of time, the heating pipe 600 is turned off, and the insulation board 400 insulates the heated air.

[0035] When the heating pipe is repaired, the push bar 304 is pulled manually, and the push bar 304 moves to drive the engaging tooth 307 to move, so that the engaging tooth 307 is separated from the arc-shaped tooth plate 204. At this time, the spring 305 is in a compressed state, and then the push block 202 is pulled manually, and the push block 202 moves to drive the engaging block 203 to move, and the engaging block 203 moves to drive the arc-shaped tooth plate 204 to move, and finally the arc-shaped tooth plate 204 is moved out of the docking frame 300, and then the first outer cover 100 is separated from the second outer cover 101. At this time, the first magnet 401 and the second magnet 403 that attract each other are separated, and the first outer cover 100 and the second outer cover 101 are removed, and the heating pipe body 102 can be repaired at this time.

[0036] According to the above working process, it can be known that: the arc-shaped guide rail is provided so that the arc-shaped tooth plate 204 can be moved, and the engaging teeth 307 are provided so that the engaging teeth 307 can be engaged with the arc-shaped tooth plate 204, so that the first outer cover 100 and the second outer cover 101 can be connected, thereby making it more convenient to disassemble the insulation board 400, improving the disassembly efficiency of the insulation board 400, and avoiding damage to the insulation board 400.

[0037] By means of the heating tube 600, the air between the first outer cover 100, the second outer cover 101 and the heating pipe body 102 can be heated, thereby providing heat to the outer wall of the heating pipe body 102, so that the outer wall of the heating pipe is in a heating state; by means of the heat preservation plate 400, the heated air between the first outer cover 100, the second outer cover 101 and the heating pipe body 102 can be insulated; by means of the first magnet 401 and the second magnet 403, the two heat preservation plates 400 can be connected to form a whole, thereby avoiding the deterioration of the heat preservation effect of the heat preservation plates 400; by means of the two heat preservation plates 400 and the two heating tubes 600, the entire antifreeze structure can be separated from the heating pipe body 102, thereby being able to effectively antifreeze the periphery of the heating pipe body 102, thereby avoiding the damage of the heating pipe body 102.

[0038] Further Figure 4 and Figure 8 As shown, the two insulation plates 400 are close to each other and are provided with mounting grooves 402 at the top and bottom of one side, a number of evenly distributed first magnets 401 are fixed in the mounting grooves 402 on one side, and a number of evenly distributed second magnets 403 are fixed in the mounting grooves 402 on the other side, and there are four first magnets 401 and four second magnets 403 respectively.

[0039] By providing the first magnet 401 and the second magnet 403 , the two heat-insulating plates 400 can be connected to form a whole, thereby preventing the heat-insulating effect of the heat-insulating plates 400 from being deteriorated.

[0040] Further Figure 6 As shown, the inner wall of the fixing frame 500 is provided with a plurality of vent holes 501 distributed in a circumference.

[0041] By providing the vent holes 501 , when the heating tube 600 is heated, hot air can move smoothly around the heating pipe body 102 , thereby avoiding the situation where the contact surface between the fixing frame 500 and the heating pipe body 102 cannot be heated.

[0042] Further Figure 3 As shown, side frames 502 are fixed to both sides of the outer wall of the fixing frame 500 , and the side frames 502 are fixed to the inner walls of the first outer cover 100 and the second outer cover 101 , respectively.

[0043] By providing the side frames 502 , the two fixing frames 500 can be connected to the first outer cover 100 and the second outer cover 101 respectively, so as to fix the positions of the first outer cover 100 and the second outer cover 101 .

[0044] In summary: when the heating pipe body 102 is to be protected from freezing, the heating pipe 600 is started, and the heating pipe 600 heats the air between the first outer cover 100, the second outer cover 101 and the heating pipe body 102. The heated air provides heat to the outer wall of the heating pipe body 102, so that the outer wall of the heating pipe is in a heating state. The heated air can pass through the vent 501, so that the contact surface between the fixing frame 500 and the heating pipe body 102 is also in a heating state. After heating for a period of time, the heating pipe 600 is turned off, and the insulation board 400 performs insulation treatment on the heated air.

[0045] When the heating pipe is repaired, the push bar 304 is pulled manually, and the push bar 304 moves to drive the engaging tooth 307 to move, so that the engaging tooth 307 is separated from the arc-shaped tooth plate 204. At this time, the spring 305 is in a compressed state, and then the push block 202 is pulled manually, and the push block 202 moves to drive the engaging block 203 to move, and the engaging block 203 moves to drive the arc-shaped tooth plate 204 to move, and finally the arc-shaped tooth plate 204 is moved out of the docking frame 300, and then the first outer cover 100 is separated from the second outer cover 101. At this time, the first magnet 401 and the second magnet 403 that attract each other are separated, and the first outer cover 100 and the second outer cover 101 are removed, and the heating pipe body 102 can be repaired at this time.
