[0002] Chinese utility model patent CN221351113U discloses a performance testing device for waterproof membranes used in construction. It includes a base and a testing box and a water storage tank mounted on top of the base. A door is hinged to the front of the testing box, and a magnifying glass is embedded near the bottom of the door. Electric push rods are connected to both sides of the testing box, and the piston rods of both electric push rods pass through the testing box and are connected to electric clamps. This utility model utilizes a door, a magnifying glass, a waterproof membrane body, a humidity sensor, a display screen, and a testing box in conjunction. Multiple humidity sensors, arranged in a dotted pattern, simultaneously detect the humidity on the bottom surface of the waterproof membrane, thereby testing its waterproof performance. This allows workers to assess the degree of damage to the waterproof membrane even when its waterproof performance has only minor defects by observing the bottom surface through the magnifying glass and the humidity displayed on the humidity sensor screen. This effectively tests the waterproof performance of the membrane.

[0003] The aforementioned utility model patent uses a two-sided clamping method to test waterproof membranes. This testing method has the following drawbacks: if there is a lot of water on the top of the waterproof membrane, some of the water will flow downwards to the edge of the waterproof membrane, causing the water to fall downwards and resulting in test failure; if there is little water on the top of the waterproof membrane, the test is prone to inaccurate due to insufficient water.

[0004] Therefore, we propose a performance testing device for waterproof membranes to address the problems mentioned above. Utility Model Content

[0022] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] A waterproof membrane performance testing device includes a testing cylinder 1, and a cover plate 2 is installed at the opening at the top of the testing cylinder 1; the cover plate 2 serves to close the testing cylinder 1.

[0024] In detail: Rotary supports 16 are symmetrically fixed on the outer surface of the upper part of the detection cylinder 1. The same rotating shaft 17 is fixed between the two rotating supports 16, and a rotating sleeve 18 is rotatably mounted on the rotating shaft 17. An "L"-shaped bracket 19 is fixed on the outer surface of the rotating sleeve 18. The "L"-shaped bracket 19 can drive the rotating sleeve 18 to rotate along the axis of the rotating shaft 17. A cover plate 2 is fixed to one end of the "L"-shaped bracket 19, so that the cover plate 2 can be opened or closed on the detection cylinder 1.

[0025] In detail: The outer surface of the upper part of the detection cylinder 1 is also equipped with a buckle 20 (the buckle is already in the prior art and will not be described in detail in this application); the outer surface of the cover plate 2 is fixed with an "L" shaped hook 21. When the buckle 20 is fastened to the upper part of the "L" shaped hook 21, it plays a locking role.

[0026] A placement plate 5 is installed on the upper part of the inside of the detection cylinder 1; and a placement hole 6 is opened in the center of the placement plate 5. The placement hole 6 is used to store the water collection box 3. The water collection box 3 is used to collect water that leaks from the waterproof membrane. Several drainage holes 12 are opened at the bottom of the water collection box 3. The drainage holes 12 are used to drain the leaked water. It should be noted that an annular protrusion 7 is fixed on the outer surface of the top of the water collection box 3. The outer diameter of the annular protrusion 7 is larger than the diameter of the placement hole 6. The annular protrusion 7 is used to limit the water collection box 3 and prevent the water collection box 3 from falling downward due to gravity.

[0027] A water collection hood 4, which is opposite to the water collection box 3, is fixed at the center of the top of the cover plate 2. The water collection hood 4 is used to store accumulated water. It should be noted that both ends of the water collection hood 4 are open, so that the water inside the water collection hood 4 can flow downward and test the waterproof performance of the waterproof membrane. It should also be noted that the water collection hood 4 has a certain depth to prevent the accumulated water from overflowing from the water collection hood 4.

[0028] In detail: A ring-shaped pressure plate 8 is fixed at the center of the bottom of the cover plate 2; a ring-shaped support plate 11 is fixed at the center of the top of the placement plate 5, and the ring-shaped pressure plate 8 and the ring-shaped support plate 11 are coaxially arranged. Through the cooperation of the ring-shaped pressure plate 8 and the ring-shaped support plate 11, the waterproof membrane to be tested can be clamped to prevent the waterproof membrane from being loosened during the testing process, thus affecting the accuracy.

[0029] More specifically: An annular groove 9 is provided on one side of the annular pressure plate 8, and a sealing rubber gasket 10 is bonded inside the annular groove 9. The sealing rubber gasket 10 serves two purposes: firstly, it protects the waterproof membrane and prevents damage caused by excessive clamping force on the waterproof membrane; secondly, it increases the sealing effect and prevents water in the water collection cover 4 from flowing out from the gap between the annular pressure plate 8 and the waterproof membrane.

[0030] The inside of the detection cylinder 1 is also equipped with a mounting plate 13, which is located below the water collection box 3. A downwardly recessed drain cover 14 is integrally formed at the center of the mounting plate 13. Through the setting of the drain cover 14, the water discharged from the water collection box 3 can be collected. It should be noted that the drain cover 14 is inverted conical in shape, so that the collected water can flow towards the middle part. A drain pipe 15 is fixed at the center of the bottom of the drain cover 14. An opening 22 is opened at the bottom of the detection cylinder 1. One end of the drain pipe 15 extends through the opening to the outside of the detection cylinder 1, so that the detected water can be discharged to the outside of the detection cylinder 1.

[0031] When installing the waterproof membrane: First, loosen the fastener 20 from the "L"-shaped hook 21. Then, rotate the cover plate 2 upwards so that it can rotate around the axis of the rotating shaft 17, thus opening the cover plate 2. Place the waterproof membrane to be tested on the placement plate 5, completely covering the placement hole 6 with the waterproof membrane. Then close the cover plate 2 again. The sealing rubber gasket 10 at the bottom of the cover plate 2 can squeeze the waterproof membrane, which can tighten and seal the waterproof membrane. Finally, fasten the fastener 20 to the "L"-shaped hook 21 to lock it in place.

[0032] When testing the waterproof performance of the waterproof membrane: first, water is poured into the water collection hood 4, and the waterproof membrane can support the water in the water collection hood 4; if the water in the water collection hood 4 slowly seeps into the waterproof membrane, it means that the waterproof membrane is unqualified. The seeping water can flow into the water collection box 3, and the water in the water collection box 3 flows into the interior of the drainage cover 14 through several water outlets 12, so that the water in the drainage cover 14 is discharged through the drainage pipe 15, thereby completing the test of the waterproof membrane.
