Description

Technical Field

[0002] Waterproof coating is an important building material, mainly used to prevent rainwater, groundwater and other liquids from penetrating into buildings or structures, thereby protecting the dryness and safety of the interior of the building. The main function of waterproof coating is waterproofing. Quality testing can verify whether it can effectively prevent moisture penetration in various environments and ensure that the building is not damaged by moisture.

Current waterproof coating quality inspection devices can usually only inspect the surface of the waterproof coating layer, and it is difficult to find water leakage problems hidden inside or deep inside. Moreover, after completing the impermeability test, the current waterproof coating quality inspection device requires staff to manually move the waterproof coating sample to another location for applicability testing under low temperature conditions, which not only increases the labor intensity of the staff, but may also cause time delays and increased errors in the testing process.

[0036] Working principle: when the staff inspects the quality of the waterproof coating, the staff first applies the waterproof coating to be inspected on the surface of the cloth, and the staff pours the inspection water into the interior of the inspection box 1 so that the water falls on the top of the lifting plate 5, and then the staff moves the cloth coated with the waterproof coating sample to the bottom of the fixed frame 3, and the staff rotates the knobs 44 on both sides, so that the positioning plate 43 squeezes and fixes the two sides of the cloth coated with the waterproof coating sample. After the fixation is completed, the staff turns on the second motor 61 on both sides, and the output shaft of the second motor 61 drives the second screw 63 on both sides to rotate, and pushes the lifting plate 5 up through the push rod 65, so that the water on the surface of the lifting plate 5 contacts the bottom of the cloth coated with the waterproof coating sample under the fixed frame 3. At this time, the staff turns on the driving motor 81 and the infrared imager 9, and the rotating rod 84 drives the infrared imager 9 to rotate, and the surface of the cloth coated with the waterproof coating sample is irradiated and captured by the infrared imager 9. The infrared imager 9 transmits the information to the interior of the console 2, and displays the detection information and images on the display screen on the surface of the console 2, so that the staff can inspect the waterproof coating. The waterproof performance of the material is analyzed. After the preliminary inspection, the staff controls the lifting plate 5 to descend and turns on the refrigerator 26. The refrigerator 26 cools the detection water above the lifting plate 5. After the temperature of the detection water drops to a certain temperature, the staff turns on the second motor 61 again, so that the lifting plate 5 pushes the cooled detection water to move up and contact the bottom of the cloth coated with the waterproof coating sample again, so that the cloth coated with the waterproof coating sample is lowered. At this time, the staff turns on the first motor 11, and then the output shaft of the first motor 11 drives the first reciprocating screw 12 to rotate, and the moving block 13 moves left and right on the surface of the first reciprocating screw 12, so that the rotating roller 18 reciprocates left and right above the cloth coated with the waterproof coating sample. When the rotating roller 18 moves, the third threaded sleeve 158 drives the rotating roller 18 to move up and down, and the surface of the cloth is subjected to a bending test through the detection plate 19. After multiple movements, the staff turns on the infrared imager 9 again, and detects the surface of the cloth coated with the waterproof coating sample again to evaluate the adaptability of the coating in a low temperature environment, so as to complete the detection of the quality of the waterproof coating.
