[0035] This utility model proposes a waterproof coating testing device.

[0036] In the embodiments of this utility model, such as Figures 1 to 6 As shown, the waterproof coating testing equipment includes:

[0037] Water receiving tank 1, the top of which has an opening 11 connecting the interior and exterior spaces of the water receiving tank 1;

[0038] A clamping assembly, comprising a drive unit and a gripper 24, wherein the drive unit is located at the bottom of the water receiving tank 1 and has a mounting portion protruding from the end face of the water receiving tank 1;

[0039] The gripper is configured to hold one end of the fabric to be tested. The gripper is located on the mounting part and below the opening 11. The driving unit is used to drive the gripper away from or near the end face of the water tank 1.

[0040] The air extraction component 3 has an air inlet connected to the water receiving tank 1, and is used to extract air from the water receiving tank 1.

[0041] The side wall forming the opening 11 of the water receiving tank 1 is used to place the fabric to be tested. The fabric to be tested is larger than the area of ​​the opening 11, so that the fabric to be tested can cover the opening 11 during testing. The drive unit can be a cylinder, hydraulic cylinder, linear motor, etc. The drive unit is located at the lower part of the water receiving tank 1, which can be located on the bottom surface of the water receiving tank 1 (i.e., the surface of the bottom of the water receiving tank 1) or on one side of the water receiving tank 1, without specific restrictions. The gripper 24 is used to hold one end of the fabric to be tested. The type of gripper is not specific, as long as it can fix one end of the fabric to be tested. The gripper is located on the drive unit so that when the gripper holds the fabric to be tested, it can pull the fabric to be tested taut. The gripper is lower than the side wall forming the opening 11 so that when the gripper pulls the fabric to be tested, the end of the fabric to be tested pulled by the gripper can better fit against the side wall forming the opening 11, thereby reducing the entry of external gas into the water receiving tank 1.

[0042] The air extraction component 3 can be a water ring vacuum pump, centrifugal fan, etc. When the air extraction component 3 extracts air, a high negative pressure is not required. It is only necessary to form a negative pressure to accelerate the penetration of water into the fabric to be tested. The air inlet of the air extraction component 3 is located on the upper side of the water receiving tank 1 and on the lower side of the side wall forming the opening 11.

[0043] Working principle: During use, the fabric to be tested is laid on the upper part of the water tank 1, so that the fabric can cover the opening 11. The clamp 24 holds one end of the fabric to be tested, and waterproof coating is applied to the fabric. To reduce false tests, the area of ​​the waterproof coating on the fabric is larger than the opening 11, and the waterproof coating covers the opening 11. After the waterproof coating dries, the fabric to be tested is pulled down around the opening 11 by hand in coordination with the clamp 24, so that the surface of the fabric can better fit the side forming the opening 11, thereby better sealing the opening 11. After sealing the opening 11, water can be manually sprayed onto the fabric to be tested with the waterproof coating. At the same time, the air extraction component 3 is activated, which reduces the air pressure in the water tank 1. If the waterproof coating is not waterproof enough, the water will quickly penetrate to the other side of the fabric under the negative pressure in the water tank 1. Thus, the test is completed. It should be noted that when a greater vacuum is required, it can be achieved by pressing the test fabric against the side wall of the opening 11. The test fabric can be framed and set accordingly. In this way, the air entering the water tank 1 through the thickness direction of the fabric can be reduced.

[0044] This utility model of waterproof coating testing equipment features a water tank 1 with an opening 11. A drive unit is located at the lower part of the water tank 1, and a clamp 24 is mounted on the mounting part. The clamp is configured to hold one end of the fabric to be tested, allowing it to pull the fabric. Because the clamp is lower than the opening 11 of the water tank, it pulls the fabric downwards, ensuring better contact between the fabric and the opening 11. An air extraction component 3 extracts gas from the water tank 1, creating a negative pressure. After the waterproof coating is applied to the surface of the fabric and dries, the fabric protruding from the opening 11 is pulled downwards by hand in conjunction with the clamp. Water is then sprayed onto the coated fabric, and the air extraction component 3 is activated. This allows for rapid testing of the waterproof performance of the coating. The pre-test pulling of the fabric also allows for simultaneous testing of the coating's elasticity. In addition, since this waterproof coating testing equipment only has a water tank 1, a drive unit, a clamp 24 and an air extraction component 3, the structure of the water coating testing equipment is simple, the production cost is lower, and it is easy to promote and use.

[0045] In some instances, such as Figures 3 to 5 As shown, the drive unit includes a moving component 21, a drive element 215, and a transmission disk 23. The transmission disk 23 is disposed on the output shaft of the drive element 215, which is located below the water receiving tank 1. The moving component 21 includes a guide rail 211, a slider 212, a mounting base 213, and a transmission element 214. One end of the guide rail 211 is adjacent to the circumference of the transmission disk 23, and the other end extends away from the circumference of the transmission disk 23. The slider 212 is slidably disposed on the guide rail 211. The guide rail 211 has a mounting base 213 mounted on the slider 212. The mounting base 213 extends along the length of the guide rail 211. One end of the transmission member 214 is rotatably connected to the transmission disk 23, and the other end is rotatably connected to the mounting base 213, so that the driving member 215 can drive the mounting base 213 to move along the length of the guide rail 211 through the transmission disk 23 and the transmission member 214. The mounting base 213 has a mounting portion away from the transmission disk 23.

[0046] The driving component 215 is a motor. The driving component 215 can be set on the bottom surface of the water receiving tank 1 or on the lower side of the water receiving tank 1. The driving component 215 can be connected to the water receiving tank 1 or there can be no connection between them. The specific details are not described here. When the driving component 215 is not connected to the water receiving tank 1, a support frame or column can be set at the bottom of the water receiving tank 1.

[0047] In some instances, such as Figures 3 to 5As shown, the transmission component 214 is V-shaped, with one end of the transmission component 214 connected to the transmission disk 23 near the edge of the transmission disk 23. The drive disk is circular, and the end of the transmission component 214 connected to the drive disk is close to the edge of the drive disk. Thus, when the transmission disk 23 rotates, the transmission disk 23 can drive the transmission component 214 to have a larger displacement.

[0048] In some instances, such as Figures 3 to 5 As shown, the drive component 215 is located at the bottom of the water receiving tank 1 and in the center of the ground. There are four moving parts 21, arranged at intervals along the circumference of the transmission disc 23. There are also four grippers, each corresponding to one of the moving parts 21. This design helps save manpower.

[0049] In some instances, such as Figure 2 As shown, the waterproof coating testing equipment also includes a water storage tank 5 and a water pump 9. The receiving tank 1 is located on top of the water storage tank 5, and the drive unit is located between the water storage tank 5 and the receiving tank 5. The water pump 9 is located in the water storage tank 5, and its inlet is connected to the water storage tank 5. The water pump 9 is used to transport water from the water storage tank 5 to the surface of the fabric to be tested. The waterproof coating testing equipment also includes a connecting pipe 6 and a valve 7. One end of the connecting pipe 6 is connected to the water storage tank 5, and the other end is connected to the receiving tank 1. The valve 7 is located in the connecting pipe 6 so that it can pass through the short connecting pipe 6. The waterproof coating testing equipment also includes multiple support columns 8, which are located between the receiving tank 1 and the water storage tank 5 to directly form an installation space 4. The drive unit is located in the installation space 4. The water storage tank 5 is a transparent tank. The air extraction assembly 3 is a centrifugal fan. The water receiving tank 1 is a transparent tank.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
