[0002] Asphalt waterproof coating is a solvent-based or water-emulsion waterproof coating configured with asphalt as the base material. Solvent-based asphalt waterproof coating refers to the coating configured by directly dissolving unmodified petroleum asphalt in solvents such as gasoline, also known as cold primer. Water-emulsion asphalt waterproof coating refers to the coating formed by dispersing petroleum asphalt in water under the action of chemical emulsifiers or mineral emulsifiers to form a stable water dispersion. Before the use of asphalt waterproof coating, its waterproof performance needs to be detected. After retrieval: A waterproof property detection device for waterproof coating with the Chinese patent number CN218766530U, including a detection platform, a support frame, a heating box and a blower. A support frame is installed on the top of the detection platform, a main air duct is installed at the top end of the support frame, an air outlet duct is installed at the bottom of the main air duct, a second air duct is installed at the top of the main air duct, and a heating box is installed on the top of the detection platform.

[0003] However, the above-mentioned waterproof property detection device for asphalt waterproof coating still has deficiencies. The non-woven fabric coated with asphalt waterproof coating is placed in the detection box without being fixed, and it is prone to move during detection, which affects the sealing performance between the non-woven fabric and the detection box, thereby reducing the detection accuracy. At the same time, it is rather troublesome and inconvenient to take, place and replace the non-woven fabric coated with asphalt waterproof coating. Therefore, we propose a waterproof property detection device for asphalt waterproof coating to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned drawbacks and propose a waterproof property detection device for asphalt waterproof coating.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0023] In the present utility model, the fixing component includes a fixing screw 18 threadedly connected to the top of the fixed frame 19. The bottom end of the fixing screw 18 is rotatably connected to a pressing plate 21. Both pressing plates 21 are movably abutted against the top of the non-woven fabric 20. The pressing plate 21 is slidably connected to the inner wall of one side of the fixed frame 19. A bearing 22 is fixedly connected to the top of the pressing plate 21. The pressing plate 21 is rotatably connected to the bottom end of the fixing screw 18 through the bearing 22. A hand wheel is fixedly connected to the top end of the fixing screw 18. The non-woven fabric coated with asphalt waterproof coating is laid on the mesh plate 16, and then the fixing screw 18 is rotated through the hand wheel. The fixing screw 18 drives the pressing plate 21 to move downward to press and fix the non-woven fabric, avoiding displacement during detection and affecting the accuracy of detection.

[0024] In the present utility model, the disassembly, installation, taking and placing component includes two rotating shafts 9 rotatably connected to the top of the detection box 2, two torsion springs 8 fixedly connected to the top of the detection box 2, and a vertical plate 7 fixedly connected to the top of the fixed frame 19. A pulling plate 11 is fixedly connected to the top of the vertical plate 7. The top ends of the torsion spring 8 and the rotating shaft 9 on the same side are fixedly connected to the same limiting plate 10. The pulling plate 11 is movably abutted between the limiting plate 10 and the detection box 2. The limiting plate 10 is pulled outwards so that the limiting plate 10 does not hinder the downward movement of the pulling plate 11. Then, the mesh plate 16, the non-woven fabric 20, the fixed frame 19, and the vertical plate 7 are placed on the top of the support plate 15 in the detection box 2, and the pulling plate 11 is abutted against the top of the detection box 2. Then, the limiting plate 10 is released. At this time, under the torsion of the torsion spring 8, the limiting plate 10 reversely resets and abuts against the top of the pulling plate 11, thereby limiting and fixing the pulling plate 11 and the mesh plate 16, further preventing the mesh plate 16 and the non-woven fabric from being displaced during detection. When taking out, the limiting plate 10 is pulled outwards, and the mesh plate 16 and the non-woven fabric 20 can be pulled out through the pulling plate 11.

[0025] In the present utility model, the two torsion springs 8 are respectively sleeved on the outer sides of the corresponding rotating shafts 9, which is convenient for guiding and limiting the torsion springs 8 and making their torsion more stable.

[0026] In the present utility model, support plates 15 are fixedly connected to the inner walls on both sides of the detection box 2. The mesh plate 16 is movably placed on the tops of the two support plates 15, which is convenient for supporting the mesh plate 16.

[0027] In the present utility model, the spraying detection liquid assembly includes a water pump 12 and a colored liquid tank 13 fixedly connected to the top of the frame body 3. The water pump 12 is communicated with the bottom on one side of the colored liquid tank 13. The bottom of the water pump 12 is fixedly communicated with a water spraying pipe 17. The bottom of the water spraying pipe 17 is fixedly communicated with a plurality of spray heads 14. The colored liquid in the colored liquid tank 13 is pumped into the water spraying pipe 17 by the water pump 12, and finally sprayed out from the spray heads 14 and flows onto the top of the non-woven fabric 20 in the detection box 2. When there is more colored liquid, the water pump 12 is turned off.

[0028] In the present utility model, a colored liquid discharge pipe 6 with a valve is fixedly communicated with the rear side of the detection box 2. A drain pipe 5 is fixedly communicated with the bottom on one side of the detection box 2. An observation window 4 is fixedly connected to the front side of the detection box 2. By opening the valve on the colored liquid discharge pipe 6, the remaining colored liquid can be discharged and collected for reuse. The sewage can be discharged through the drain pipe 5. Through the observation window 4, the color of the clear water in the detection box 2 can be observed. If the color of the clear water changes, it indicates that the waterproof performance of the asphalt waterproof coating is poor. On the contrary, if the color of the clear water does not change, it indicates that the waterproof performance of the asphalt waterproof coating is good.

[0029] In the present utility model, during detection, appropriate clear water is injected at the bottom of the detection box 2. The non-woven fabric coated with bituminous waterproof coating is laid on the mesh plate 16. Then, the fixing screw 18 is rotated by the handwheel, and the fixing screw 18 drives the pressing plate 21 to move downward to press and fix the non-woven fabric, preventing displacement during detection and affecting the accuracy of detection. The limiting plate 10 is toggled outwards so that the limiting plate 10 does not hinder the downward movement of the pulling plate 11. Then, the mesh plate 16, the non-woven fabric 20, the fixing frame 19, and the vertical plate 7 are placed on the top of the support plate 15 in the detection box 2, and the pulling plate 11 abuts against the top of the detection box 2. Then, the limiting plate 10 is released. At this time, under the torque of the torsion spring 8, the limiting plate 10 reversely resets and abuts against the top of the pulling plate 11, thereby limiting and fixing the pulling plate 11 and the mesh plate 16, further preventing the mesh plate 16 and the non-woven fabric from being displaced during detection. Then, the colored liquid in the colored liquid tank 13 is pumped into the spray pipe 17 by the water pump 12 and finally sprayed out from the nozzle 14 and flows into the detection box 2 on the top of the non-woven fabric 20. When there is more colored liquid, the water pump 12 is turned off. Through the setting of the observation window 4, the color of the clear water in the detection box 2 can be observed. If the color of the clear water changes, it indicates that the waterproof performance of the bituminous waterproof coating is poor. On the contrary, if the color of the clear water does not change, it indicates that the waterproof performance of the bituminous waterproof coating is good. After the detection is completed, when it is necessary to replace the non-woven fabric, the valve on the colored liquid discharge pipe 6 is opened, and the remaining colored liquid can be discharged and collected for reuse. According to the above steps, the limiting plate 10 is toggled outwards, and then the mesh plate 16 and the non-woven fabric 20 can be pulled out through the pulling plate 11. The fixing screw 18 is loosened, so that the fixing screw 18 drives the pressing plate 21 to move upwards and does not fix the non-woven fabric 20, and the detected non-woven fabric can be removed. At the same time, after discharging the sewage through the drain pipe 5 and injecting clear water, the next non-woven fabric 20 can be installed and detected for use.

[0030] The above is only a preferred specific embodiment 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, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
