[0001] This utility model relates to the field of waterproof performance testing technology, and in particular to a device for testing the performance of waterproof materials. Background Technology

[0002] Waterproofing materials are used to prevent water penetration and erosion, and are widely used in various industries. Rubber and plastic waterproofing materials are frequently used in water pipe fittings. Before being put into use, waterproofing materials typically need to be tested using appropriate testing equipment to ensure their waterproofing performance meets standards. Current testing methods for waterproofing materials usually involve wetting the surface with flowing water. However, during water spraying, it is impossible to guarantee uniform wetting of the waterproofing material, leading to inconsistent water penetration and significant errors in the waterproofing performance test. Therefore, there is an urgent need for a waterproofing material performance testing device with smaller wetting uniformity errors. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Reference Figure 1 This utility model provides a waterproof material performance testing device, including a vertically arranged mounting plate 1, a base plate 2 fixedly connected to the bottom side of the mounting plate 1, a lifting plate 3 slidably connected to the side of the mounting plate 1, the lifting plate 3 being located above the base plate 2, a lifting assembly installed between the lifting plate 3 and the base plate 2, a box being arranged above the lifting plate 3, the box being fixedly connected to the mounting plate 1, the box including a water supply tank 4 and a water outlet tank 5 that are interconnected, a water outlet 6 being opened at the bottom of the water outlet tank 5, the water outlet 6 being correspondingly arranged with the lifting plate 3; a pressure application assembly being installed inside the water outlet tank 5. The waterproof material to be tested is placed on the lifting plate 3, and then the lifting assembly moves the lifting plate 3 upward, bringing it into contact with the water outlet tank 5. This clamps the waterproof material between the water outlet tank 5 and the lifting plate 3. Water is then supplied to the water outlet tank 5 through the water supply tank 4, ensuring that the water makes uniform and sufficient contact with the inner ring of the waterproof material. The waterproof material is tested by detecting the amount of water seepage through the outer ring. The pressure application assembly can increase the pressure of the water flow on the waterproof material, thereby enabling the testing of the maximum waterproof performance of the waterproof material.

[0016] The design is further optimized so that the lifting assembly includes two first connecting rods 7 rotatably connected to the top surface of the base plate 2, and two second connecting rods 8 rotatably connected to the bottom surface of the lifting plate 3. Each second connecting rod 8 corresponds to one of the first connecting rods 7, and the corresponding first connecting rods 7 and second connecting rods 8 are rotatably connected via connecting shafts. A telescopic electric cylinder 9 is rotatably connected between the two connecting shafts. The telescopic electric cylinder 9 drives the two connecting shafts to move, thereby increasing the angle between the first connecting rods 7 and the second connecting rods 8, thus lifting the lifting plate 3 and causing it to move upwards.

[0017] The design is further optimized so that the water supply tank 4 is a ring-shaped tank, located around the outlet tank 5. The top of the water supply tank 4 is provided with an inlet 10, and the top wall of the outlet tank 5 is provided with a vent 11.

[0018] The scheme is further optimized. The pressure application component includes a moving plate 12 located inside and slidably connected to the water outlet tank 5. The moving plate 12 is adapted to the water outlet tank 5. A vent hole 13 is provided on the moving plate 12. A limit box 14 is fixedly connected to the moving plate 12 corresponding to the vent hole 13. The limit box 14 is connected to the vent hole 13. A through hole 15 is provided at the bottom of the side wall of the limit box 14. A pressure plate 16 is slidably connected inside the limit box 14. The pressure plate 16 is set corresponding to the vent hole 13. A hydraulic rod 17 is fixedly connected to the top of the water outlet tank 5. The bottom end of the hydraulic rod 17 slides through the limit box 14 and is fixedly connected to the pressure plate 16. A limit ring 18 is fixedly connected to the inner wall of the water outlet tank 5. The limit ring 18 is in contact with the top surface of the moving plate 12. An annular baffle 19 is fixedly connected to the top surface of the moving plate 12. Several compression springs 20 are fixedly connected between the annular baffle 19 and the limit ring 18. The hydraulic rod 17 drives the pressure plate 16 downward, thereby sealing the vent 13. Then, the moving plate 12 moves downward to pressurize the water, which facilitates the testing of the peak waterproof performance of the waterproof material. When not pressurized, the vent 13, through hole 15, and vent 11 can be connected to the outside, thus ensuring air circulation during water filling without affecting the internal pressure.

[0019] Further optimization of the scheme, using a hydraulic device to drive the hydraulic rod 17 is a conventional technical means, which will not be elaborated here.

[0020] The design is further optimized by incorporating a return channel 21 within the lifting plate 3. One end of the return channel 21 is located in the middle of the top surface of the lifting plate 3, and the other end is connected to a return pipe 22, which is connected to the water supply tank 4. This allows water in the outlet tank 5 to flow back into the water supply tank 4 after testing, preventing water waste.

[0021] To further optimize the design, a submersible pump is installed at the connection between the water supply tank 4 and the water outlet tank 5 to control the water flow and prevent backflow; a water pump is also installed at the connection between the return pipe 22 and the water supply tank 4.

[0022] The working process of this utility model is as follows: In use, the ring-shaped waterproof material to be tested is placed on the lifting plate 3. Then, the telescopic electric cylinder 9 drives the two connecting shafts to move, thereby increasing the angle between the first connecting rod 7 and the second connecting rod 8, thus lifting the lifting plate 3 and causing it to move upwards, making the waterproof material tightly adhere to the bottom wall of the outlet tank 5. Water is then supplied to the outlet tank 5 through the water supply tank 4, ensuring sufficient contact between the water and the inner ring of the waterproof material, facilitating the testing of its waterproof performance. When pressure testing of the waterproof material's peak performance is required, only the hydraulic rod 17 needs to be activated. The hydraulic rod 17 drives the pressure plate 16 downwards, sealing the vent 13, and then drives the moving plate 12 downwards, thus pressurizing the water and facilitating the testing of the waterproof material's peak performance.

[0024] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
