[0026] Embodiment 1

[0027] A high-altitude anti-freezing pipeline, as Figures 1 to 4As shown in the figure, it includes a pipe body 1. Both ends of the pipe body 1 are fixedly connected with connecting rings 2. A plurality of positioning holes 5 are formed in the side wall of the connecting ring 2. The connecting rings 2 at one end of the two pipe bodies 1 are connected through a connecting sleeve 3. A temperature detection component 4 is arranged on the outer wall of the connecting sleeve 3. Bolts 6 are arranged at both ends of the connecting sleeve 3. The bolts 6 are in threaded fit with the positioning holes 5. Positioning strips 7 are arranged on the outer walls of the pipe body 1 and the connecting sleeve 3. The pipe body 1 includes an outer pipe 8 and an inner pipe 11. The outer pipe 8 is sleeved on the outer wall of the inner pipe 11. A heat conduction layer 10 and a heat insulation layer 9 are sequentially arranged between the inner pipe 11 and the outer pipe 8. The heat conduction layer 10 is in limit fit with the outer wall of the inner pipe 11 through limit protrusions. A plurality of heating wires 18 are arranged on the inner wall of the heat conduction layer 10. The connecting sleeve 3 includes an outer sleeve 12 and an inner sleeve 13. The inner sleeve 13 is fixedly connected to the inner wall of the outer sleeve 12. There are gaps between the two ends of the inner sleeve 13 and the inner wall of the outer sleeve 12. The temperature detection component 4 includes a bimetallic strip 14 and a first conductive contact 15. The bimetallic strip 14 is arranged inside the outer sleeve 12. The first conductive contact 15 is arranged at one end of the bimetallic strip 14. A second conductive contact 16 opposite to the first conductive contact 15 is arranged on one side of the bimetallic strip 14. The first conductive contact 15 is connected to the power supply circuit. The second conductive contact 16 is electrically connected to a conductive contact arranged on the inner wall of the connecting sleeve 3.

[0028] During installation, the interconnected outer pipe 8, heat insulation layer 9 and heat conduction layer 10 are sleeved on the outer wall of the inner pipe 11. The limit protrusions are clamped into the outer wall of the heat conduction layer 10 to make the heat conduction layer 10 in limit fit with the inner pipe 11. Then the connecting ring 2 is inserted between the outer sleeve 12 and the inner sleeve 13. The relative angle between the pipe body 1 and the connecting sleeve 3 is determined by the positioning strips 7 arranged on the outer walls of the pipe body 1 and the connecting sleeve 3, so that the heating wires 18 can contact and conduct electricity with the conductive contacts arranged on the inner wall of the connecting sleeve 3. The bolts 6 are screwed into the positioning holes 5 to connect the connecting sleeve 3 with the connecting ring 2. Then the combination of another pipe body 1 and the connecting ring 2 is connected to the other end of the connecting sleeve 3. When the external environment drops to a certain level, the bimetallic strip 14 deforms due to cold, making the first conductive contact 15 contact and conduct electricity with the second conductive contact 16. The heating wires 18 are energized to generate heat. The outer sleeve 12 conducts the heat generated by the heating wires 18, so that the heat is evenly distributed on the outer wall of the inner pipe 11 to heat and keep warm the inner pipe 11. When the inner pipe 11 is being repaired, the connecting sleeve 3 can be removed, and the inner pipe 11 can be pulled out from the heat conduction layer 10 to repair the inner pipe 11.

[0029] By arranging the connecting ring 2, the connecting sleeve 3, the outer pipe 8, the heat insulation layer 9 and the heat conduction layer 10, during installation and repair, the combination of the outer pipe 8, the heat insulation layer 9 and the heat conduction layer 10 can be directly sleeved on the outer wall of the inner pipe 11. When repair is needed, the inner pipe 11 can be pulled out and only the inner pipe 11 can be removed and replaced, and the operation is fast.

[0030] By providing a temperature detection component 4, when the external environment drops to a certain level, the bimetal strip 14 deforms due to cold, causing the first conductive contact 15 to contact and conduct electricity with the second conductive contact 16, and the heating wire 18 is energized to generate heat. Compared with controlling heating and heat preservation through a temperature sensor, the control logic is simplified and the energy consumption is lower.

[0031] Embodiment 2

[0032] A high-altitude anti-freezing pipeline. On the basis of Embodiment 1, the following improvements are made as Figure 4 shown. A heating detection component 17 is provided on the inner wall of the inner sleeve 13. The heating detection component 17 has the same structure as the temperature detection component 4. The second conductive contact 16 in the temperature detection component 4 is electrically connected to the first conductive contact 15 in the heating detection component 17. The second conductive contact 16 in the heating detection component 17 is electrically connected to the heating wire 18.

[0033] When the inside of the inner pipe 11 reaches a certain temperature, the bimetal strip 14 in the heating detection component 17 is bent by heat, driving the first conductive contact 15 to separate from the second conductive contact 16, and the heating wire 18 is powered off, avoiding excessive heating of the heating wire 18, achieving automatic temperature control, and without increasing energy consumption.

[0034] By providing the heating detection component 17, when the inside of the inner pipe 11 reaches a certain temperature, the heating wire 18 is powered off, achieving automatic temperature control, and without increasing energy consumption.

[0035] Working principle: During installation, the interconnected outer tube 8, thermal insulation layer 9, and heat conduction layer 10 are sleeved on the outer wall of the inner tube 11. The limit protrusion is snapped into the outer wall of the heat conduction layer 10 to make the heat conduction layer 10 and the inner tube 11 in limit fit. Then, the connecting ring 2 is inserted between the outer sleeve 12 and the inner sleeve 13. The relative angle between the pipeline main body 1 and the connecting sleeve 3 is determined by the positioning strips 7 provided on the outer walls of the pipeline main body 1 and the connecting sleeve 3, so that the heating wire 18 can contact and conduct electricity with the conductive contacts provided on the inner wall of the connecting sleeve 3. The bolt 6 is screwed into the positioning hole 5 to connect the connecting sleeve 3 and the connecting ring 2. Then, the combination of another pipeline main body 1 and the connecting ring 2 is connected to the other end of the connecting sleeve 3; when the external environment drops to a certain level, the bimetallic strip 14 deforms due to cold, making the first conductive contact 15 and the second conductive contact 16 contact and conduct electricity. The heating wire 18 is energized and generates heat. The outer sleeve 12 conducts the heat generated by the heating wire 18, making the heat evenly distributed on the outer wall of the inner tube 11 to heat and keep warm the inner tube 11. When the temperature inside the inner tube 11 reaches a certain level, the bimetallic strip 14 in the heating detection component 17 is bent by heat, driving the first conductive contact 15 and the second conductive contact 16 to separate, and the heating wire 18 is powered off to avoid excessive heating of the heating wire 18, realizing automatic temperature control without additional energy consumption; when overhauling the inner tube 11, the connecting sleeve 3 can be removed, and the inner tube 11 can be pulled out from the heat conduction layer 10 for overhauling the inner tube 11.
