[0021] 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.
[0022] Please refer to Figures 1-4. The building waterproofing material testing device includes a housing 1. A test groove 2 is provided at the top of the housing 1. A base frame 3 is fixed inside the test groove 2. A U-shaped water trough 4 is fixed on the inner wall of the test groove 2, and the U-shaped water trough 4 is located below the base frame 3. A gantry frame 5 is fixed at the top of the housing 1. A hydraulic telescopic device 6 is installed at the top of the gantry frame 5. An annular pressure block 7 is fixed downward at the output end of the hydraulic telescopic device 6, and the annular pressure block 7 is located directly above the base frame 3. A transparent observation window 8 is provided on the housing 1 at the test groove 2. A drying chamber 9 is provided inside the housing 1 below the test groove 2. A dryer 10 is installed in the drying chamber 9. Two rotating shafts 11 are symmetrically rotatably connected inside the housing 1. The drying chamber 9 and the test groove 2 are connected at the rotating shafts 11. A test cloth 12 is wound around the two rotating shafts 11, and one side of the test cloth 12 is located in the test groove 2. The other side is located inside the drying chamber 9. A motor 13 is installed inside the housing 1. The output end of the motor 13 is fixed to one of the rotating shafts 11. A transmission wheel 14 is fixed on the rotating shaft 11. The two rotating wheels are driven by a transmission belt 15.
[0023] When using this device, the waterproof membrane is placed on the base frame 3. The hydraulic telescopic device 6 is activated, which moves the annular pressure block 7 downwards to contact and fix the waterproof membrane. At the same time, the annular pressure block 7 forms a groove with the waterproof membrane, and water is injected into the groove. If the waterproof membrane leaks, the water will drip onto the detection cloth 12 below. The watermark formed by the water droplets is observed through the transparent observation window 8. The presence of a watermark indicates leakage, while the absence of a watermark indicates good waterproofing. When the detection cloth 12 is wet with watermarks, the next test is performed. The motor 13 is activated, which drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the detection cloth 12 to rotate, causing the wet part to rotate into the drying chamber 9. The dryer 10 is then activated to dry it. At the same time, the dried part rotates to the bottom of the base frame 3 for easy inspection next time. After one test of the waterproof membrane, the hydraulic telescopic device 6 is activated again, which moves the annular pressure block 7 upwards. At this time, the water will flow on the surface of the waterproof membrane, flowing outwards and into the surrounding U-shaped water tank 4.
[0024] In actual use, it was found that the waterproof board would slip when placed on the base frame 3. In order to avoid the above problem, in this embodiment, the top of the base frame 3 is fixed with an anti-slip pad 16.
[0025] In actual use, it was found that the annular pressure block 7 forms a groove after contacting the waterproof membrane. Water may be left in the gap after being injected. In order to avoid the above-mentioned problem, in this embodiment, a sealing gasket 17 is fixed at the bottom of the annular pressure block 7.
[0026] In actual use, it was found that, in order to facilitate the discharge of water vapor from the drying chamber 9, ventilation slots 18 are provided on both the front and rear sides of the drying chamber 9 in this embodiment.
[0027] In actual use, it was found that in order to facilitate the drainage of water from the U-shaped water tank 4, in this embodiment, the housing 1 is provided with a drain outlet 19, which is connected to the U-shaped water tank 4.
[0028] In actual use, it was found that the device is easily moved by external forces during operation. In order to avoid the above problem, in this embodiment, a plurality of support legs 20 are fixed at the bottom of the housing 1, and the bottom of the support legs 20 is provided with anti-slip texture.
