[0020] Reference Figure 1 , the support rings 2 and the support rods 3 are arranged in an array of 2 meters in groups according to the length of the pipeline;

[0021] By adopting the above technical solution, the support rings 2 and the support rods 3 can be evenly arranged according to the actual pipeline length to ensure the stability of the support.

[0022] Reference Figure 1 , aerogel is provided on the surface of the inner protection tube 1 and the insulation tube 4;

[0023] By adopting the above technical solution, aerogel can effectively prevent heat from being transferred through radiation and convection.

[0024] Reference Figure 3 The connection structure 8 includes a porous ring 81, a connecting column 82 is provided on one side of the porous ring 81, a limiting block 83 is provided on one end of the connecting column 82, a spring 84 is sleeved on the side where the connecting column 82 and the limiting block 83 are close to each other, and a limiting ring 85 is provided on one side of the inner protection tube 1 and the connecting tube 9;

[0025] By adopting the above technical solution, when the connection is made, the two sets of limit blocks 83 are used, and the limit blocks 83 drive the connecting column 82 to move backward, so that the water flows out through the limit ring 85.

[0026] Reference Figure 3 , the limiting block 83 is of a mushroom cap type, and the limiting ring 85 is of a flared type;

[0027] By adopting the above technical solution, under normal conditions, the limit block 83 is located at the expanded opening of the limit ring 85 to achieve a sealed state. When connecting, the limit block 83 moves backward to allow water to flow out through the fiber ring 85.

[0028] Reference Figure 3 , one side of the surface of the inner protection tube 1 is provided with a positive thread 11, one side of the surface of the connecting tube 9 is provided with a reverse thread 12, and one end of the connecting tube 9 is provided with a fixing ring 13;

[0030] The implementation principle of the heat insulation structure of the connecting pipe of an air source heat pump in the embodiment of the present application is as follows: when the pipe is insulated, the inner protection pipe 1 and the insulation pipe 4 are supported by the support ring 2 and the support rod 3 to form a vacuum layer 6, and the heat insulation is performed by vacuum, and the heat insulation effect is good. The support ring 2 and the support rod 3 can be evenly arranged according to the actual pipe length to ensure the stability of the support. The support ring 2 and the support rod 3 are both made of rubber, which has good heat insulation and elasticity, and can prevent possible thermal expansion and vibration of the pipe. The filling layer 5 is made of polytetrafluoroethylene, which has good corrosion resistance and high temperature resistance. Yes, they can effectively resist chemical corrosion and high temperature and ensure the stability of sealing performance. When the pipeline is connected, since the limit blocks 83 in the inner protective tube 1 and the connecting tube 9 are located at the flared part of the limit ring 85, a sealing state is achieved. When connecting, the two sets of limit blocks 83 are used, and the limit blocks 83 drive the connecting column 82 to move backward, so that the water flows out through the limit ring 85, and then the inner protective tube 1 and the connecting tube 9 are fixedly connected through the fixing ring 13. The use of this structure can effectively avoid the heat loss generated by the pipeline in the process of transporting hot water or cold water, ensure the efficient operation of the system, and save unnecessary energy loss.
