[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 5 The device for testing the performance of a radiation insulation coating shown includes a testing chamber 1. A testing sensor 13 is fixedly connected to the inner bottom wall of the testing chamber 1. A heating chamber 2 is fixedly connected to the upper side of the testing chamber 1. Multiple heating elements 24 are arranged inside the heating chamber 2. A feeding assembly is arranged inside the testing chamber 1. The feeding assembly includes a feeding trough 11, an equipment support 3, a drive shaft 31, a drive disc 32, an electric motor 33, a conveyor belt 34, a positioning block 35, and a support pad 36. Multiple coating plates 4 are arranged on the upper side of the conveyor belt 34. Feeding troughs 11 are opened on both the front and rear surfaces of the testing chamber 1. A baffle 12 is fixedly connected to the inner wall of the testing chamber 1 above the feeding trough 11. Ventilation holes 14 are opened on both the left and right sides of the testing chamber 1. Sealing plates 15 are hinged to the sides of the ventilation holes 14.

[0027] During the testing process, multiple sets of coating panels 4 are placed sequentially on the upper side of the conveyor belt 34. At this time, the feeding component feeds multiple sets of coating panels 4 into the interior of the heating box 2 through the feeding chute 11, realizing the simultaneous feeding and unloading. At this time, the heating element 24 is activated to heat the upper side of the coating panel 4. The detection sensor 13 detects the temperature of the lower side of the coating panel 4, thereby determining the heat insulation performance of the coating.

[0028] After the coating board 4 inside the testing chamber 1 is tested, when testing the next set of coating boards 4, the sealing plate 15 is opened to open the ventilation hole 14 to ventilate the inside of the testing chamber 1. When the coating board 4 is completely sent into the testing chamber 1, the sealing plate 15 is used to seal the ventilation hole 14 again, and the coating board 4 is tested again.

[0029] participate Figure 1 and Figure 5 The left and right sides of the equipment bracket 3 are fixedly connected to the left and right side walls of the detection box 1, respectively. The inner sides of the front and rear ends of the equipment bracket 3 are rotatably connected to the drive shafts 31. The electric motor 33 is fixedly installed on the right side surface of the equipment bracket 3 near the front end. The output end of the electric motor 33 is fixedly connected to the right end of the front drive shaft 31. The left and right ends of the two drive shafts 31 are fixedly connected to the drive discs 32. The conveyor belt 34 is connected to the two drive discs 32 on the front and rear sides. Multiple positioning blocks 35 are fixedly connected to the surface of the conveyor belt 34. Support pads 36 are fixedly connected to the inner walls of the left and right sides of the equipment bracket 3. The two sets of support pads 36 and the two sets of conveyor belts 34 pass through the left and right ends of the two sets of feed troughs 11, respectively.

[0030] Specifically, during the feeding process, the paint plate 4 is sequentially positioned between multiple sets of positioning blocks 35 to prevent the paint plate 4 from shifting, so that the paint plate 4 can be accurately delivered into the detection box 1. After the paint plate 4 is placed, the electric motor 33 is started. The output end of the electric motor 33 drives the front transmission shaft 31 to rotate. The transmission shaft 31 drives the two sets of front transmission discs 32 to rotate. At this time, the front and rear transmission discs 32 cooperate to drive the conveyor belt 34 to rotate, thereby conveying the paint plate 4 backward.

[0031] In addition, after a set of paint panels 4 are sent into the testing chamber 1, a gap will appear on the front side of the conveyor belt 34. At this time, the untested paint panels 4 are placed in the gap so that the paint panels 4 can be tested continuously, thereby effectively improving the testing efficiency.

[0032] See Figure 3 and Figure 4 A hydraulic cylinder 22 is fixedly installed on the upper end of the heating chamber 2. A mounting bracket 23 is fixedly connected to the lower end of the piston rod in the hydraulic cylinder 22. The heating element 24 is fixedly installed on the lower surface of the mounting bracket 23. Positioning rods 26 are fixedly connected to the inner walls on both the left and right sides of the heating chamber 2. Positioning sleeves 25 are fixedly connected to both the left and right sides of the mounting bracket 23. The positioning sleeves 25 are slidably connected to the positioning rods 26. A window is opened on the front surface of the detection chamber 1. A viewing panel 21 is fixedly connected inside the window.

[0033] Meanwhile, during the testing process, the height of the mounting bracket 23 can be adjusted by the hydraulic cylinder 22, which in turn adjusts the height of the heating element 24, allowing the heating element 24 to heat the coating plate 4 at different heights. This enables the performance of the coating plate 4 at different distances from the heating point to be tested, further improving the testing accuracy.

[0034] The working principle of this utility model is as follows: Multiple sets of coating plates 4 are sequentially fed into the detection chamber 1 by the feeding assembly. The heating element 24, together with the detection sensor 13, sequentially detects the multiple sets of coating plates 4, which effectively improves the convenience of loading and unloading the coating plates 4 and improves the detection efficiency. At the same time, the piston rod in the hydraulic cylinder 22 drives the mounting frame 23 to move up and down, which in turn drives the heating element 24 to move up and down, adjusting the distance between the heating element 24 and the coating plate 4, and further improving the detection accuracy.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
