[0002] Most of my country is in the northern temperate zone. In winter, the weather is cold overall, especially in most parts of the north. In extreme weather conditions, the temperature even reaches below zero degrees Celsius. Therefore, heating has become an indispensable part of people's daily life. According to national and international product standards, the raw materials for the production of plastic pipes and plastic pipe fittings for hot and cold water must be special pipe materials that have been tested and qualified in accordance with GB / T18252-2000 "Determination of the long-term hydrostatic strength of thermoplastic plastic pipes for plastic pipe systems by extrapolation". In other words, each raw material manufacturer must make a creep failure curve that meets the predicted strength reference curve according to the floor heating pipe product standard to prove that the raw materials sold are qualified.

[0003] In cold weather, sudden heating will cause the temperature of the pipe to change drastically, and the sudden change in temperature may cause rupture damage to the pipe or affect the service life of the pipe, which will cause heat to be lost during the pipe transfer process, resulting in a waste of thermal resources. If the pipe is ruptured, it needs to be replaced, which will also result in a large waste of manpower and material resources.

[0004] In view of such a situation, the purpose of the utility model is to provide an electrically preheated long-distance heating pipeline with adjustable temperature, so as to solve the problem that sudden heating will cause the pipeline temperature to change suddenly, and the sudden change of cold and hot may cause rupture damage to the pipeline or affect the service life of the pipeline, thereby causing heat loss in the pipeline transfer process, resulting in a waste of thermal resources, and the pipeline rupture requires replacement, which will also lead to a large amount of manpower and material resources. Waste the problem. Utility Model Content

[0023] The operation of the motor 5 can drive the first gear 6 to rotate, and then drive the second gear 7 meshing with the first gear 6 to rotate. The rotation of the second gear 7 can drive the first bidirectional screw 3 coaxially fixed with the second gear 7 to rotate, and then the first bidirectional screw 3 drives the heater 2 to reciprocate back and forth, cooperating with the operation of the heater 2. The heater 2 transfers its own heat to the heating pipe, and then the heating pipe 1 can be preheated. This process is carried out before the heating operation, and then the temperature of the pipe is controlled. When the heating operation starts, the pipe has been preheated and the temperature is adjusted, which greatly ensures the safety of the pipe use and avoids the waste of heat resources and manpower and material resources caused by pipe damage.

[0024] Specifically, both ends of the first bidirectional screw 3 are non-threaded cylindrical, and both are rotatably mounted with bearings 14, the bearings 14 are fixed to the outer wall of the heating pipe 1, and the second gear 7 is coaxially fixed to the cylindrical side wall of one end of the bidirectional screw.

[0025] The first bidirectional screw 3 is rotatably mounted on the outer wall of the heating pipe 1, which can ensure the stability of the first bidirectional screw 3 during rotation, and further ensure the stability of the heater 2 during reciprocating motion.

[0026] Specifically, a plurality of rollers 4 are rotatably mounted on the side wall of the heater 2 , and the outer wall of the roller 4 is an arc-shaped surface structure, and the arc-shaped surface of the roller 4 is in contact with the outer wall of the heating pipe 1 .

[0027] The arc surface structure of the outer wall of the roller 4 can better fit with the heating pipe 1, ensuring the stability of the operating state of the heater 2.

[0028] Specifically, a through hole is opened at a position symmetrical to the first bidirectional screw 3 of the heater 2, and a second bidirectional screw 9 is arranged horizontally in the through hole. Both ends of the second bidirectional screw 9 are non-threaded cylindrical and are rotatably installed with bearings 14. The bearings 14 are fixed to the outer wall of the heating pipe 1, and an internal threaded sleeve 10 is threadedly installed on the outer wall of the second bidirectional screw 9.

The rotation of the rotating ring 12 drives a number of cleaning brushes 13 fixedly connected to the inner wall of the rotating ring 12 to rotate. The end of the cleaning brush 13 rubs against the heating pipe 1 to wipe and clean the outer wall of the heating pipe 1, so as to prevent the dust on the outer wall of the heating pipe 1 from affecting the operation of the heater 2. While cleaning the outer wall, the temperature regulation work of the heating pipe 1 by the heater 2 can be further ensured, so as to prevent the dust on the outer wall of the heating pipe 1 from affecting the heat transfer from the heater 2 to the heating pipe 1.

[0031] Specifically, a central controller 8 is fixed to the side wall of the motor 5 , and the central controller 8 is electrically connected to the motor 5 and the heater 2 .

[0032] Working principle: When temperature adjustment is required, the operator starts the heater 2 and the motor 5 by sending a command to the central controller 8. The operation of the motor 5 can drive the first gear 6 to rotate, and then drive the second gear 7 meshing with the first gear 6 to rotate. The rotation of the second gear 7 can drive the first bidirectional screw 3 coaxially fixed with the second gear 7 to rotate, and then the first bidirectional screw 3 drives the heater 2 to reciprocate back and forth, cooperating with the operation of the heater 2. The heater 2 transfers its own heat to the heating pipe, and then the heating pipe 1 can be preheated.

[0033] It should be mentioned that during the operation of the heater 2, the second bidirectional screw 9 will be driven to rotate, and then the second bidirectional screw 9 will drive the internal threaded sleeve 10 to rotate, and then the internal threaded sleeve 10 will drive the swivel 12 to rotate through the friction of the rubber gasket 11 sleeved on the outer wall. The rotation of the swivel 12 drives a number of cleaning brushes 13 fixedly connected to the inner wall of the swivel 12 to rotate. The end of the cleaning brush 13 rubs against the heating pipe 1 to wipe and clean the outer wall of the heating pipe 1, so as to prevent the dust on the outer wall of the heating pipe 1 from affecting the operation of the heater 2. While cleaning the outer wall, the temperature regulation work of the heating pipe 1 by the heater 2 can be further ensured, so as to prevent the dust on the outer wall of the heating pipe 1 from affecting the heat transfer from the heater 2 to the heating pipe 1.
