[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7 This utility model provides a technical solution: a device for testing the insulation effect of a thermal insulation pipe, comprising: a testing box 1, a first motor 2, a transmission mechanism 3, an adjusting rod 4, a connecting frame 5, an electric telescopic rod 6, a support frame 7, a pipe body 8, a cold water pipe 9, a refrigeration unit 10, a cover plate 11, an adjusting roller 12, a second motor 13, a fixing plate 14, a guide roller 15, and an electric heating tube 16; Specific Implementation

[0031] Existing thermal insulation performance testing devices for insulated pipes are inconvenient to install and disassemble. To solve this technical problem, this implementation example is attached. Figure 1 Appendix Figure 2 Appendix Figure 4 and attached Figure 5As shown, when the first motor 2 is turned on, the first motor 2 drives the transmission mechanism 3 installed at its output end to run. The transmission mechanism 3 drives the adjusting rods 4 installed symmetrically at the front and rear below it to rotate simultaneously. The adjusting rods 4 drive the connecting frame 5 connected to the outer thread to rise, so that the connecting frame 5 slides on the outside of the detection box 1 connected to it in the slot. The connecting frame 5 drives the electric telescopic rod 6 installed on the upper inner side to rise and fall. Adjust the height of the electric telescopic rod 6 and the support frame 7, turn on the electric telescopic rod 6, and the electric telescopic rod 6 pushes the support frame 7 installed at its output end to move. Adjust the position of the support frame 7 according to the length of the pipe body 8, fill the medium in the pipe body 8 and seal the pipe body 8. Then place the pipe body 8 on the support frame 7 so that the pipe body 8 and the support frame 7 with the longitudinal section of the "C" shape are connected in the slot.

[0032] Turn on the first motor 2 to reverse the adjustment rod 4. The adjustment rod 4 drives the connecting frame 5 to descend. The connecting frame 5 drives the electric telescopic rod 6 and the support frame 7 to descend. The support frame 7 supports the pipe body 8 to descend, so that the pipe body 8 enters the test box 1. Specific Implementation

[0033] Existing methods are inconvenient for simulating different weather conditions and their detection results are not good enough. To solve this technical problem, this implementation example is attached. Figure 1 -Appendix Figure 3 Appendix Figure 6 and attached Figure 7 As shown, when the second motor 13 is turned on, the second motor 13 drives the adjusting roller 12 installed at its output end to rotate. The adjusting roller 12 drives the cover plate 11 that is meshed with it to move. The cover plate 11 slides between the connecting frame 5 that is connected to it in the slot, so that the cover plate 11 covers the top of the detection box 1. The cover plates 11, which are symmetrically distributed front and back, cover the pipe body 8. When the cover plate 11 slides, the guide roller 15 is tightly attached to the bottom of the cover plate 11. The guide roller 15, which are evenly distributed, rotates in the fixed plate 14, which plays a supporting and auxiliary role for the cover plate 11 and ensures the stability of the cover plate 11.

[0034] Turn on the refrigeration unit 10, which supplies cold air to the cold water pipe 9, causing the temperature inside the test chamber 1 to drop. Alternatively, turn on the power to the electric heating tube 16, causing the temperature inside the test chamber 1 to rise. The pipe body 8 simulates the state under different weather conditions inside the test chamber 1. After the simulation is completed, the adjusting roller 12 moves the cover plate 11 to open it. Then, the height adjustment mechanism lifts the pipe body 8. The temperature of the medium inside the pipe body 8 is then measured to obtain the insulation condition of the pipe body 8 at different temperatures.
