[0027] Embodiment 1

[0028] A silica aerogel thermal insulation testing device, as Figures 1 to 3As shown in the figure, it includes a housing 1. On one side of the outer wall of the top end of the housing 1, a display control panel 2 is provided. A plurality of linearly arranged placement grooves 3 are formed on the outer wall of the top end of the housing 1. The placement grooves 3 are in a square shape with an opening. The housing 1 divides the interior of the housing 1 into a water storage chamber 8 and a heating chamber 9 through a fixing plate 7. The water storage chamber 8 is located at the bottom end of the housing 1. The bottom end of the placement groove 3 is communicated with the heating chamber 9. A heating plate 10 is fixed on the outer wall of the top end of the fixing plate 7. A condensation dehumidification mechanism 15 and a spray head 13 are provided on the side wall of the heating chamber 9. Both the air inlet end and the air outlet end of the condensation dehumidification mechanism 15 are communicated with the heating chamber 9. A temperature and humidity probe 14 is provided on the side wall of the heating chamber 9. A water pump 11 is installed on the inner wall of the water storage chamber 8. The output end of the water pump 11 is communicated with the spray head 13 through a connecting pipe 12. A connecting frame 4 is provided on one side of the placement groove 3. A fixing rod 5 is rotatably connected to the connecting frame 4 in a damped manner. A temperature sensor 6 is provided on the outer wall of the bottom end of the fixing rod 5. The rotation angle of the fixing rod 5 is limited to 90 degrees. The temperature sensor 6 is located at the center of the placement groove 3. The temperature sensor 6, the heating plate 10, the water pump 11, the temperature and humidity probe 14, and the condensation dehumidification mechanism 15 are all electrically connected to the central processor. The water outlet end of the condensation dehumidification mechanism 15 is communicated with the water storage chamber 8 through a return pipe 16.

[0029] During detection, lift the fixing rod 5 upward. At this time, samples of different coatings can be placed in the placement groove 3, and then rotate the fixing rod 5 back to its original position. The temperature sensor 6 contacts the top end of the sample to detect the temperature at the top end of the sample. Then, control the temperature and humidity inside the heating chamber 9 through the display control panel 2. The temperature and humidity probe 14 detects the temperature and humidity in the heating chamber 9 and adjusts the humidity according to the set temperature and humidity by heating through the heating plate 10 and through the cooperation of the condensation dehumidification mechanism 15 and the water pump 11. When the humidity in the heating chamber 9 is higher than the set humidity, the condensation dehumidification mechanism 15 performs condensation dehumidification on the air in the heating chamber 9. The dried air after dehumidification flows back into the heating chamber 9, and the generated condensed water flows into the water storage chamber 8 through the return pipe 16. When the humidity in the heating chamber 9 is lower than the set humidity, the water pump 11 is started, and the water in the water storage chamber 8 is pumped through the connecting pipe 12 to the spray head 13 and sprayed as water mist to increase the humidity in the heating chamber 9.

[0030] By setting the water pump 11, the connecting pipe 12, the spray head 13, the temperature and humidity probe 14, and the condensation dehumidification mechanism 15, the humidity in the heating chamber 9 can be adjusted, and the heat preservation performance of the coating under different humidity conditions can be detected.

[0031] By setting the water storage chamber 8 and the return pipe 16, the condensed water generated after the condensation dehumidification mechanism 15 dehumidifies can be recycled and stored, realizing the recycling of water resources for humidification.

[0032] Embodiment 2

[0033] An aerogel thermal insulation test device. In this embodiment, based on Embodiment 1, the following improvements are made. As Figure 1 , Figure 4 shown, elastic clamping plates 17 are arranged on both sides of the placement groove 3. The elastic clamping plates 17 are rotatably connected to the outer wall of the top end of the housing 1. The bottom end of the elastic clamping plate 17 is lower than the top height after the sample is placed in the placement groove 3. A sealing strip 18 is fixed to the inner wall of the bottom end of the placement groove 3.

[0034] When placing the sample, rotate the elastic clamping plates 17 on both sides of the placement groove 3 by 90 degrees so that the elastic clamping plates 17 do not hinder the placement of the sample. After the sample is placed, reset the elastic clamping plates 17. Since the bottom end of the elastic clamping plate 17 is lower than the top height after the sample is placed in the placement groove 3, the elasticity of the elastic clamping plate 17 itself will press down the sample, and the sealing performance of the heating chamber 9 after the sample is placed in the placement groove 3 is improved through the sealing strip 18.

[0035] By setting the elastic clamping plates 17 and the sealing strip 18, the sealing performance of the heating chamber 9 after the sample is placed in the placement groove 3 is improved, avoiding the influence of the external environment on the inside of the heating chamber 9 and causing detection errors.

[0036] Working principle: During detection, lift the fixing rod 5 upward and rotate the elastic clamping plates 17 on both sides of the placement groove 3 by 90 degrees so that the elastic clamping plates 17 do not hinder the placement of the sample. At this time, samples of different coatings can be placed in the placement groove 3. After the sample is placed, reset the elastic clamping plates 17. Since the bottom end of the elastic clamping plate 17 is lower than the top height after the sample is placed in the placement groove 3, the elasticity of the elastic clamping plate 17 itself will press down the sample, and the sealing performance of the heating chamber 9 after the sample is placed in the placement groove 3 is improved through the sealing strip 18. Then rotate the fixing rod 5 back to its original position. The temperature sensor 6 contacts the top end of the sample to detect the temperature at the top end of the sample. Then, the temperature and humidity inside the heating chamber 9 are controlled through the display control panel 2. The temperature and humidity probe 14 detects the temperature and humidity in the heating chamber 9 and adjusts the humidity according to the set temperature and humidity by heating through the heating plate 10 and through the cooperation of the condensation dehumidification mechanism 15 and the water pump 11. When the humidity in the heating chamber 9 is higher than the set humidity, the condensation dehumidification mechanism 15 performs condensation dehumidification on the air in the heating chamber 9, and the dried air after dehumidification flows back into the heating chamber 9, and the generated condensed water flows into the water storage chamber 8 through the return pipe 16. When the humidity in the heating chamber 9 is lower than the set humidity, the water pump 11 is started, and the water in the water storage chamber 8 is pumped through the connecting pipe 12 to the spray head 13 and sprayed as water mist to increase the humidity in the heating chamber 9.

[0037] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
