The weather outdoors is changeable, especially in winter when there is strong wind, the temperature will drop sharply. In order to prevent the HVAC pipes from freezing, they need to be antifreeze.

[0003] The existing HVAC pipe antifreeze technology usually involves wrapping a layer of insulation material around the outside of the pipe wall to prevent freezing. However, after a long period of exposure to wind and rain, the outdoor insulation layer will greatly reduce its protective effect on the pipe in the cold winter. At the same time, the temperature changes rapidly, and simple insulation can no longer solve the problem of pipe freezing and cracking. Utility Model Content

[0008] Preferably, the curved outer wall surfaces of the two curved shells are both provided with an adjustment device, the adjustment device comprises a U-shaped seat, the U-shaped seat is fixedly mounted on the curved outer wall surface of the curved shell, a rotating shaft is rotatably connected between the inner walls on both sides of the U-shaped seat, a rotating plate is fixedly mounted on the outer wall surface of the rotating shaft, a photovoltaic panel is fixedly mounted on the side of the rotating panel, and the photovoltaic panel and the battery are electrically connected.

[0010] Preferably, a rectangular plate is fixedly mounted on one side surface of the U-shaped seat, and a spring is fixedly mounted between the rectangular plate and the movable plate. The arrangement of the spring has the effect of limiting the position of the movable plate inside the groove.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, by setting an auxiliary device, when the device needs to be used, firstly, the two arc-shaped shells are located on both sides of the pipeline body, and then the rotating wheel is rotated, and the rotation of the rotating wheel drives the threaded rod to rotate. Since the threads on the surface of the threaded rod are mutually reverse threads with the rotating wheel as the center, when the rotating wheel drives the threaded rod to rotate, the two movable plates connected by the threads on its surface will move toward each other on the surface of the sliding rod, and the two movable plates move toward each other on the surface of the sliding rod, driving the two connecting rod boxes to move toward each other, and the two connecting rods move toward each other, driving the two arc-shaped shells in the sliding groove.

During subsequent use, the temperature sensor can monitor the temperature in real time. When the external ambient temperature is lower than a certain value, the resistance wire inside the cavity is started to heat the arc-shaped shell. When the arc-shaped shell is heated, the heat is transferred to the heat conduction plate, and then the heat is transferred to the circumferential outer wall of the pipe body through the heat conduction plate and the insulation layer, thereby heating the pipe to prevent the pipe from being frostbitten. Through the cooperation of the above structure, the anti-cold effect is better than that of the traditional wrapping method.

[0013] 2. In the utility model, by setting an adjustment device, when there is sunshine, the photovoltaic panel can be used to convert solar energy into electrical energy and store it inside the battery. At the same time, when the angle of the photovoltaic panel needs to be adjusted during use, the movable plate is first slid to make the movable plate move inside the groove. The movement of the movable plate inside the groove will squeeze the spring, so that the spring is compressed. At the same time, the movement of the movable plate inside the groove also drives the round rod to move. The movement of the round rod makes it move out of the inside of the round hole. The separation of the round rod and the round hole makes the rotating shaft lose its limit. At this time, the rotating plate can be rotated, and the rotation of the rotating plate drives the photovoltaic panel to rotate. When the photovoltaic panel is rotated to a suitable angle, the movable plate is released, and the rebound force of the spring is used to reinsert the round rod into the corresponding round hole, so as to re-limit the rotation of the rotating shaft. Through the cooperation of the above structure, the angle of the photovoltaic panel can be adjusted, so that the photovoltaic panel can effectively maximize the utilization of energy.

[0028] In this embodiment, the threaded rod 304 is provided to drive the movable plate 307 to move on the surface of the sliding rod 306 .

[0029] Specifically, a cavity 314 is provided inside the arc-shaped shell 302, a through groove 309 is provided on the inner wall surface of one side of the cavity 314, a heat insulating layer 310 is fixedly installed on the arc-shaped inner wall surface of the arc-shaped shell 302, a heat conducting plate 311 is fixedly installed on the arc-shaped outer wall surface of the heat insulating layer 310, a battery 312, two resistance wires 313 and a temperature sensor 315 are fixedly installed on the inner wall surface of one side of the cavity 314, the battery 312 and the resistance wire 313 are electrically connected, and the temperature sensor 315 and the resistance wire 313 are electrically connected.

[0030] In this embodiment: the curved outer wall surfaces of the two curved outer shells 302 are both provided with an adjusting device 4, the adjusting device 4 includes a U-shaped seat 401, the U-shaped seat 401 is fixedly installed on the curved outer wall surface of the curved outer shell 302, a rotating shaft 402 is rotatably connected between the inner walls on both sides of the U-shaped seat 401, a rotating plate 403 is fixedly installed on the outer wall surface of the rotating shaft 402, a photovoltaic panel 404 is fixedly installed on the side of the rotating plate 403, and the photovoltaic panel 404 and the battery 312 are electrically connected. When the sun is shining, the photovoltaic panel 404 can be used to convert solar energy into electrical energy and store it inside the storage battery 312. At the same time, when the photovoltaic panel 404 needs to adjust its angle during use, first slide the movable plate 406 to move the movable plate 406 inside the groove 405. The movement of the movable plate 406 inside the groove 405 will squeeze the spring 410, so that the spring 410 is compressed. At the same time, the movement of the movable plate 406 inside the groove 405 also drives the round rod 407 to move. The round rod 407 moves so that it moves out of the inside of the round hole 408. The rod 407 and the round hole 408 are separated so that the rotating shaft 402 loses its limit. At this time, the rotating plate 403 can be rotated. The rotation of the rotating plate 403 drives the photovoltaic panel 404 to rotate. When the photovoltaic panel 404 rotates to a suitable angle, the movable plate 406 is released, and the rebound force of the spring 410 is used to reinsert the round rod 407 into the corresponding round hole 408 to re-limit the rotation of the rotating shaft 402.

[0033] Specifically, a rectangular plate 409 is fixedly installed on one side surface of the U-shaped seat 401 , and a spring 410 is fixedly installed between the rectangular plate 409 and the movable plate 406 .

[0034] In this embodiment, the provision of the spring 410 has the effect of limiting the position of the moving plate 406 inside the groove 405 .

[0035] Working principle: by setting the auxiliary device 3, when the device needs to be used, firstly, the two arc-shaped shells 302 are located on both sides of the pipe body 1, and then the rotating wheel 305 is rotated. The rotating wheel 305 rotates to drive the threaded rod 304 to rotate. Since the threads on the surface of the threaded rod 304 are mutually reverse threads with the rotating wheel 305 as the center, when the rotating wheel 305 drives the threaded rod 304 to rotate, the two movable plates 307 connected by the threads on its surface will move toward each other on the surface of the sliding rod 306. The two movable plates 307 move toward each other on the surface of the sliding rod 306, driving the two connecting rods 308 to move toward each other. The two connecting rods 308 move toward each other, driving the two arc-shaped shells 30 2 move toward each other in the inside of the slide groove 301, and the two arc-shaped shells 302 move toward each other in the inside of the slide groove 301 to clamp and fix the pipeline. In the subsequent use process, the temperature sensor 315 can monitor the temperature in real time. When the external environment temperature is lower than a certain value, the resistance wire 313 in the cavity 314 is activated to heat the arc-shaped shell 302. When the arc-shaped shell 302 is heated, the heat is transferred to the heat conducting plate 311, and the heat is transferred to the circumferential outer wall of the pipeline body 1 through the heat conducting plate 311 and the heat insulating layer 310, so as to heat the pipeline and prevent the pipeline from being frostbitten. Through the cooperation of the above structure, the cold-proof effect is better than that of the traditional wrapping method. When the sun is shining, the photovoltaic panel 404 can be used to convert solar energy into electrical energy and store it inside the storage battery 312. At the same time, when the photovoltaic panel 404 needs to adjust its angle during use, first slide the movable plate 406 to move the movable plate 406 inside the groove 405. The movement of the movable plate 406 inside the groove 405 will squeeze the spring 410, so that the spring 410 is compressed. At the same time, the movement of the movable plate 406 inside the groove 405 also drives the round rod 407 to move. The round rod 407 moves so that it moves out of the inside of the round hole 408. The rod 407 and the round hole 408 are separated so that the rotating shaft 402 loses its limit. At this time, the rotating plate 403 can be rotated. The rotation of the rotating plate 403 drives the photovoltaic panel 404 to rotate. When the photovoltaic panel 404 rotates to a suitable angle, the movable plate 406 is released, and the rebound force of the spring 410 is used to reinsert the round rod 407 into the corresponding round hole 408 to re-limit the rotation of the rotating shaft 402. Through the cooperation of the above structure, the angle of the photovoltaic panel 404 can be adjusted, thereby effectively maximizing the energy utilization of the photovoltaic panel 404.
