Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a device for testing the waterproofness of waterproof coatings. Background Technology

[0002] The waterproof film formed after the waterproof coating has been cured has certain extensibility, elasticity, crack resistance, impermeability and weather resistance, and can play a role in waterproofing, seepage prevention and protection. Before using the waterproof coating, it is necessary to test whether it is waterproof.

[0003] Existing waterproof coating waterproof performance testing devices typically involve applying the waterproof coating to a fabric sample and then spraying water onto the fabric to determine the amount of water seepage. For example, Chinese utility model patent CN220305099U discloses a waterproof coating waterproof performance testing device.

[0004] However, in actual use, it is found that the above-mentioned waterproof performance testing device for waterproof coatings is designed to test by flattening and fixing the fabric sample on the testing platform and then spraying the sample with water through a spray module. However, because the fabric sample is flattened, the sprayed water is prone to side leakage on the fabric during the testing process, which affects the test results. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof coating waterproofing testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof coating waterproofing testing device, comprising a base and a testing platform mounted on the base. A humidity detection groove is formed on the upper surface of the testing platform, a water-leaking frame is placed inside the humidity detection groove, a water-leaking mesh is placed at the bottom of the water-leaking frame, and a pressure frame is placed inside the water-leaking frame. A support is mounted above the testing platform and fixed to the base. An electric push rod is fixed in the middle of the support, and the output end of the electric push rod is connected to a mounting plate. A spray box is fixed below the mounting plate. The humidity detection groove senses the liquid, and a humidity sensor detects the liquid inside the groove. A fabric sample coated with waterproof coating is placed inside the water-leaking frame, and then the pressure frame presses the fabric sample into the water-leaking frame, facilitating the spraying of water onto the fabric sample using the spray box.

[0007] As a preferred embodiment of this utility model, a handle is fixed to the side of the drain frame, and the handle is mainly for the convenience of picking up the drain frame.

[0008] As a preferred embodiment of this utility model, a hand position is provided on the side of the humidity detection slot. The hand position is mainly to facilitate the insertion of a hand, gripping the handle, and making it easy to remove the leak frame.

[0009] As a preferred embodiment of this utility model, the side of the testing platform is provided with a screw hole, and a locking bolt is provided in the screw hole. The end of the locking bolt abuts against the water leakage frame, and the water leakage frame is restricted by the locking bolt.

[0010] As a preferred embodiment of this utility model, the electric push rod is provided with parallel positioning rods on its side. The positioning rods pass through the support and are fixed to the mounting plate. The positioning rods are used to improve the stability of the mounting plate during lifting and lowering.

[0011] As a preferred embodiment of this invention, the spray box is provided with a water inlet on its side, which is used to connect to an external water injection device.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention arranges a fabric sample coated with waterproof paint on a leak-proof frame, and then uses a pressure frame to restrict the fabric sample. By arranging the fabric sample inside the leak-proof frame, side leakage can be effectively avoided when water is sprayed onto the fabric sample, thus improving the testing effect and making it highly practical.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a waterproof coating waterproofing testing device, including a base 1 and a testing platform 2 mounted on the base 1. A humidity detection groove 201 is formed on the upper surface of the testing platform 2, and a water-leaking frame 3 is installed inside the humidity detection groove 201. A water-leaking mesh 301 is installed at the bottom of the water-leaking frame 3, and a pressure frame 4 is installed inside the water-leaking frame 3. A support 5 is installed above the testing platform 2 and fixed to the base 1. An electric push rod 6 is fixed in the middle of the support 5, and the output end of the electric push rod 6 is connected to a mounting plate 7. A spray box 8 is fixed below the mounting plate 7. The humidity detection groove 201 senses liquid, and a humidity sensor is used inside the humidity detection groove 201 for sensing. A fabric sample coated with waterproof coating is placed inside the water-leaking frame 3, and then the pressure frame 4 is used to press the fabric sample into the water-leaking frame 3, so that water can be sprayed onto the fabric sample using the spray box 8.

[0024] Furthermore, a handle 302 is fixed to the side of the drain frame 3, and the handle 302 is mainly for easy handling of the drain frame 3.

[0025] Furthermore, a hand position 203 is provided on the side of the humidity detection slot 201. The hand position 203 is mainly provided to facilitate reaching in and holding the handle 302, so as to facilitate the removal of the water leakage frame 3.

[0026] Furthermore, the side of the testing platform 2 is provided with a screw hole 202, and a locking bolt is provided in the screw hole 202. The end of the locking bolt abuts against the water leakage frame 3, and the water leakage frame 3 is restricted by the locking bolt.

[0029] In summary, when using this device, simply remove the pressure frame 4 from the leaking frame 3, apply the waterproof coating to the fabric sample, place the fabric sample inside the leaking frame 3 so that it adheres to the inner wall of the leaking frame 3, then reinsert the pressure frame 4 into the leaking frame 3 to hold the fabric sample in place, then place the leaking frame 3 into the humidity detection tank 201, then screw the locking bolt into the screw hole 202 to lock and fix the leaking frame 3, then activate the electric push rod 6 to push the mounting plate 7 downwards, causing the mounting plate 7 to move the spray box 8, changing the height of the spray box 8, and then inject spray water into the spray box 8, thus spraying water onto the fabric sample. When the fabric sample leaks water, the humidity detection tank 201 senses the liquid, confirming that the sample has leaked. Based on the waterproof test of the sample under different water pressures, the waterproof performance of the waterproof coating applied to the sample surface can be detected.

[0030] It is worth noting that the entire device is controlled by a master control button.
