Detailed implementation manners

[0019] The following further elaborates on the present application in conjunction with the attached Figure 1-2 drawings.

[0020] An embodiment of the present application discloses a thermal insulation performance test device for an aerogel thermal insulation thick coating. Referring to Figure 1 and Figure 2 , it includes a box body 1 and a box door 11 provided on one side of the box body 1. A mounting seat 2 is provided on the bottom wall inside the box body 1, and the mounting seat 2 is rotatably connected to the bottom wall inside the box body 1. A mounting rod 21 is fixedly provided on the mounting seat 2. The mounting rod 21 is arranged vertically, and a plurality of test rods 3 are provided on the side wall of the mounting rod 21. The length direction of the test rods 3 is horizontal. A test block 31 is sleeved on the test rod 3. The cross-section of the test block 31 is rectangular. The test block 31 is made of relatively thin steel, and the test block 31 is a one-time use test product. When testing, several test blocks 31 can be used for the test. Open the box door 11 and rotate the mounting seat 2 to conveniently sleeve the test block 31 on the test rod 3.

[0021] Referring to Figure 1 , a heat source simulation component 4 for irradiating and heating the surface of the test block 31 is provided on the inner wall of the box body 1. The heat source simulation component 4 includes an upper light source 41, a lower light source 42, and a side light source 43. The upper light source 41 is provided on the top wall inside the box body 1, the lower light source 42 is provided on the bottom wall inside the box body 1, and the side light source 43 is provided on the side wall inside the box body 1 and two are symmetrically arranged. When different types of aerogel coatings need to be tested, different types of aerogel coatings are painted on different side walls of the test block 31, and then the upper light source 41 is used to irradiate and heat the coating at the top of the test block 31, the lower light source 42 is used to irradiate and heat the coating at the bottom of the test block 31, and the side light source 43 is used to irradiate and heat the coating on the side wall of the test block 31. By changing the brightness of the upper light source 41, the lower light source 42, and the side light source 43, the test of different side surfaces and different ambient temperatures of the test block 31 can be realized.

[0022] Referring to Figure 1 and Figure 2 , a detection groove 5 is formed on the surface of the test rod 3, a temperature sensor 51 is arranged in the detection groove 5, and the detection head of the temperature sensor 51 is in contact with the inner side wall of the test block 31. The test rod 3 is rotatably connected to the mounting rod 21, and a rotating assembly 6 is arranged between the mounting rod 21 and the test rod 3. The rotating assembly 6 includes a rotating shaft 61, a motor 62, a main bevel gear 63 and a negative bevel gear 64. A rotating cavity 211 is arranged in the mounting rod 21. The rotating shaft 61 is connected to the test rod 3 and arranged coaxially. One end of the rotating shaft 61 extends into the rotating cavity 211 and is connected to the negative bevel gear 64. The motor 62 is fixedly arranged in the rotating cavity 211 through bolts, and the driving shaft of the motor 62 is connected to the main bevel gear 63. The main bevel gear 63 meshes with a plurality of negative bevel gears 64 at the same time. After the aerogel coating on different side surfaces of the test block 31 is irradiated and heated by the heat source simulation assembly 4, the motor 62 is used to drive the main bevel gear 63 to rotate. The main bevel gear 63 abuts against a plurality of negative bevel gears 64, driving the negative bevel gear 64 and the rotating shaft 61 to rotate. The rotating shaft 61 then drives the test rod 3 to rotate. The test rod 3 drives the temperature sensor 51 to contact different positions on the inner side wall of the test block 31. The temperature change of the inner wall of the test block 31 is detected by the temperature sensor 51 to detect the heat insulation and heat preservation performance of the coating on the surface of the test block 31. One temperature sensor 51 on the test rod 3 can detect different positions of the test block 31, so as to realize the detection of the performance of different types of aerogel coatings.

[0023] Referring to Figure 1 , an adsorbent 7 is adhesively fixed on the side wall of the mounting rod 21. The adsorbent 7 is a magnet. When the test block 31 is sleeved on the test rod 3, the test block 31 is quickly fixed to the mounting rod 21 by magnetic attraction between the adsorbent 7 and the test block 31. A limiting plate 71 is integrally arranged on the adsorbent 7. When the motor 62 drives the test rod 3 to rotate, the limiting plate 71 can abut against the surface of the test block 31. The limiting plate 71 limits the rotation of the test block 31, ensuring that the temperature sensor 51 can detect different positions on the inner wall of the test block 31.

[0024] Referring to Figure 1 , a heat insulation plate 8 is arranged at one end of the test rod 3 away from the mounting rod 21. The heat insulation plate 8 is made of asbestos material. The heat insulation plate 8 can reduce the influence of the heat absorption of the test rod 3 on the detection of the temperature sensor 51 and improve the test accuracy of the temperature sensor 51.

[0025] The implementation principle of the thermal insulation performance test device for an aerogel thermal insulation thick coating in an embodiment of this application is as follows: Different types of aerogel coatings are applied to different side walls of the test block 31. Open the box door 11 and rotate the mounting seat 2 to sleeved the test block 31 on the test rod 3, and then close the box door 11. Then, use the upper light source 41 to irradiate and heat the coating at the top of the test block 31, use the lower light source 42 to irradiate and heat the coating at the bottom of the test block 31, and use the side light source 43 to irradiate and heat the coating on the side wall of the test block 31. By changing the brightness of the upper light source 41, the lower light source 42, and the side light source 43, the test of different ambient temperatures on different sides of the test block 31 can be realized. After the rated time, use the motor 62 to drive the rotation shaft 61 to rotate, the rotation shaft 61 drives the test rod 3 to rotate, and the test rod 3 drives the temperature sensor 51 to contact different positions on the inner side wall of the test block 31. The temperature change of the inner wall of the test block 31 is detected by the temperature sensor 51 to detect the heat insulation and thermal insulation performance of the coating on the surface of the test block 31. The temperature sensor 51 can detect different positions, so as to realize the detection of the performance of different types of aerogel coatings on the test block 31. Multiple aerogel coatings can be detected at one time, and the control is convenient and fast, reducing the test difficulty and improving the test efficiency.
