[0032] The thermal pipe 1 is placed in the middle of the upper antifreeze box 2 and the lower antifreeze box 3. The upper antifreeze box 2 and the lower antifreeze box 3 are both rectangular and fixed by sealing plates 4 and butterfly bolts 5. Corresponding nuts are provided at the bottom ends of the butterfly bolts 5.

[0033] The upper antifreeze box 2 and the lower antifreeze box 3 are fixedly connected to the upper pipe sealing layer 6 and the lower pipe sealing layer 7, and the upper pipe sealing layer 6 and the lower pipe sealing layer 7 are both semicircular and composed of rubber layers. The upper pipe sealing layer 6 and the lower pipe sealing layer 7 are fixedly connected to the Velcro 8, and the Velcro 8 is divided into a hook surface layer and a fleece surface layer.

[0034] The upper antifreeze box 2 and the lower antifreeze box 3 are movably connected to the heating plate 12, and the upper antifreeze box 2 and the lower antifreeze box 3 are connected and fixed to the heating plate 12 through a docking block 14.

[0035] The heating plate 12 and the heating lamp 15 are threadedly connected. The heating lamp 15 is a bathroom heater lamp and is arranged in sequence in multiples. The control panel 13 and the heating lamp 15 are electrically connected. The control panel 13 includes control buttons, a CNC display screen, a charging port, a buzzer, a battery, a main control board, a detection module, a temperature control module and a timing module. The heating plate 12 and the barrier net 16 are fixed by screws.

[0037] Specifically, the structure is composed of a thermal pipe 1, an upper antifreeze box 2, a lower antifreeze box 3, a sealing plate 4, a butterfly bolt 5, an upper pipe sealing layer 6, a lower pipe sealing layer 7, a Velcro 8, an air outlet 9, a fan body 10, a mounting groove 11, a heating plate 12, a control panel 13, a docking block 14, a heating lamp 15, a barrier net 16, a foot column 17, a spring button 18, a bottom column 19 and an adjustment hole 29 to form an antifreeze device for a heating pipe network for a thermal power plant. The thermal pipe 1 is wrapped with the upper antifreeze layer 2 and the lower antifreeze layer 3 to achieve sealing integration. The overlapping parts on both sides of the upper antifreeze layer 2 and the lower antifreeze layer 3 are sealed and fixed by using the butterfly bolt 5 and the nut through the sealing plate 4, so that the thermal pipe 1 is placed in a closed space. By arranging the heat pipe 1 during installation, The flexibility of the rubber layer of the upper pipe sealing layer 6 and the lower pipe sealing layer 7 can make the end part fit the wall of the thermal pipe 1, and the softness of the material can be matched with the thermal pipes 1 of different diameters to achieve a dead angle fit density. At the same time, the stretchability of the upper pipe sealing layer 6 and the lower pipe sealing layer 7 allows the Velcro 8 to connect and fix the upper pipe sealing layer 6 and the lower pipe sealing layer 7, and it is easy to disassemble. When the internal heating and antifreeze work is carried out through the air outlet 9, the fan body 10 is cooperated to blow hot air to the outside for ventilation, and the other end blows the outside air into the antifreeze box for air convection. The fan body 10 is provided with a Bluetooth module inside, which can be started by a Bluetooth electronic device and can be disassembled for charging. The air outlet 9 has a small aperture. It is not easy for a large amount of internal heat to escape. The heating plate 12 is formed into a drawer type through the installation groove 11, which can be disassembled, repaired and replaced in time. Hand grips are provided at both ends of one side of the heating plate 12 to facilitate the removal of the heating plate 12. The opening and closing of the heating lamp 15 in the heating plate 12 is controlled by the control panel 13. The heating lamp 15 heats the air through the heating wire. When the power is turned on, the heating wire will generate resistance heating, emit infrared radiation and heat, and heat the surrounding air. At the same time, the heating temperature and heating time can be debugged by numerical control. When the heating plate 12 is working, if the power is exhausted or a heating lamp 15 fails, the buzzer will sound through the monitoring module, and the indicator light on the control panel 13 will light up red, indicating normal operation. It lights up green during operation, ensuring the overall safety of use. At the same time, when the heating plate 12 is out of power or damaged, it can be detached and replaced with another heating plate 12 immediately to ensure continuous operation without hindering the antifreeze work. The heating plate 12 can be firmly docked with the upper antifreeze layer 2 and the lower antifreeze layer 3 through the docking block 14 to avoid air leakage during insertion. The heating lamp 15 is protected by the barrier net 16 to prevent it from accidentally falling off and breaking. After the barrier net 16 is installed, the bottom surface is flush with the heating plate 12 and will not be hindered when withdrawing or inserting. The spring button 18 is inserted into the appropriate height adjustment hole 29 through the telescopic cooperation of the foot column 17 and the bottom column 19, so that the overall height of the antifreeze box 2 can be adjusted to match the height of the thermal pipe 1.The whole system can effectively complete the antifreeze work of the heating pipe network used in the thermal power plant, and at the same time it can be adjusted for use.

[0038] Working principle: When in use, connect the external data line to the charging port of the control panel 13 to store electricity in the internal battery. By adjusting the height of the foot column 17 and the bottom column 19, the lower antifreeze box 3 is spliced ​​with the thermal pipe, and then the upper antifreeze box 2 is overlapped with the lower antifreeze box 3. The sealing plates 4 on both sides of the upper antifreeze layer 2 and the lower antifreeze layer 3 are fixed by the butterfly bolts 5 and nuts to achieve sealing. At this time, the upper pipe sealing layer 6 and the lower pipe sealing layer 7 at both ends are in a boss shape, so that the ends of the upper pipe sealing layer 6 and the lower pipe sealing layer 7 are tightly fitted to the thermal pipe 1. The Velcro 8 can be manually fitted to make the antifreeze box as a whole fully sealed, and the fan is turned on by an external electronic device. The fan body 10 allows the internal air to circulate, so that after the heating lamp 15 is turned on, the air convection can effectively reduce the formation of water vapor. At the same time, the heating plate 12 is inserted, and the docking block 14 is inserted into the corresponding groove body, so that the heating plate 12 is installed in place, and the heating lamp 15 is turned on through the control panel 13, and the heating temperature and heating time are adjusted. Because the service life of the heating plate 12 may be reduced due to long-term heating, through the simple assembly of the heating plate 12, two more heating plates 12 can be equipped for replacement and use, so that the overall service life is improved, and it is easy to maintain. The anti-freezing work of the heating pipe network of the thermal power plant can be maintained for a long time, so that the overall work efficiency is effectively improved.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
