Description

Technical Field

[0001] This utility model relates to the field of waterproof coating testing equipment, and in particular to a waterproof coating effect testing equipment. Background Technology

[0002] The waterproof film formed after the waterproof coating is cured has certain extensibility, elasticity, crack resistance, impermeability and weather resistance, and can play a role in waterproofing, seepage prevention and protection. The waterproof performance of the waterproof coating needs to be tested during the production stage.

[0003] Existing methods for testing the effectiveness of waterproof coatings typically involve a water tightness test. During this test, the system observes for any water leakage. However, since factories need to test the effectiveness of different batches of waterproof coatings, existing testing equipment cannot easily and efficiently replace the samples to be tested, thus reducing testing efficiency. Furthermore, when releasing the water tightness test, water can easily wet the testing equipment, requiring a significant amount of time to dehumidify it, which further reduces testing efficiency.

[0016] (III) Beneficial Effects

[0017] The beneficial effects of this utility model are as follows: In actual production and testing, when sampling tests are required to assess the effectiveness of waterproof coatings, the waterproof coating to be tested can be applied to the upper surface of the test block and cured to form a waterproof film. The test block is then placed in a containment groove for positioning and fixation. A linear drive unit is then activated, which, through a lifting frame, drives a connecting rod to lower the sealing ring. This causes the sealing ring to pull the telescopic tube open, pressing the sealing ring against the upper surface of the test block. The test block, sealing ring, and telescopic tube together form a cavity. The inlet / outlet water assembly then pumps water into the cavity, creating a water tightness test. After a certain period of time… If there is an abnormality in the waterproof membrane on the test block, water inside the cavity will seep into the test block through the waterproof membrane, causing an increase in humidity at the bottom of the test block. Subsequently, the humidity detection mechanism will detect the abnormal humidity at the bottom of the test block. If no abnormality is found in the waterproof membrane, the humidity detection mechanism will not show much change in the detection data. When it is necessary to release the water tightness test, the water inlet and outlet components can continue to operate to draw out the water from the cavity. Then, the linear drive component will be operated to drive the sealing ring to detach from the test block. The operator can then remove the test block from the placement slot for replacement. This allows for more convenient and efficient replacement and testing of the test sample, reduces the chance of water wetting the equipment during the release of the water tightness test, and thus improves the testing efficiency.

[0024] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to Figures 1 to 4 As shown, a waterproof coating effect testing device of this utility model includes a base 4, a frame 2, several test blocks 3, a water-tight mechanism 1, and a humidity detection mechanism. The water-tight mechanism 1 is connected to the base 4 through the frame 2. The upper part of the base 4 is provided with a placement groove adapted to the test blocks 3. The test blocks 3 are detachably connected to the placement groove. The humidity detection mechanism is provided inside the placement groove. The water-tight mechanism 1 is movably connected to the test blocks 3.

[0026] The water-tightening mechanism 1 includes an inlet / outlet water assembly, two linear drive components 105, a sealing ring 101, a lifting frame 103, several connecting rods 106, and a telescopic tube 107. Both linear drive components 105 are connected to the upper part of the frame 2. The linear drive components 105 are linearly driven connected to the upper part of the lifting frame 103. The lower part of the lifting frame 103 is connected to the upper part of the sealing ring 101 through several connecting rods 106. The inlet / outlet water assembly is connected to the frame 2. The upper part of the telescopic tube 107 is connected to the inlet / outlet water assembly. The sealing ring 101 is connected to the lower part of the telescopic tube 107. The lower part of the sealing ring 101 is movably connected to the test block 3.

[0027] The working principle of this utility model is as follows: In actual production testing, when it is necessary to sample and test the effect of waterproof coating, the waterproof coating to be tested can be applied to the upper surface of test block 3 and cured to form a waterproof film on the upper surface of test block 3. Then, test block 3 is placed in the anti-waterproof groove for limiting and fixing. Then, the linear drive 105 is operated, which drives the connecting rod 106 through the lifting frame 103 to lower the sealing ring 101, thereby causing the sealing ring 101 to pull the telescopic tube 107 to unfold, so that the sealing ring 101 is pressed against the upper surface of test block 3. A cavity is formed by the test block 3, the sealing ring 101 and the telescopic tube 107. Then, the inlet and outlet water assembly is operated. The water inlet and outlet components draw water into the formed cavity to conduct a water tightness test. After a certain period of time, if there is any abnormality in the waterproof membrane on the test block 3, the water in the cavity will seep into the interior of the test block 3 through the waterproof membrane, causing an increase in humidity in the lower part of the test block 3. Subsequently, the humidity detection mechanism will detect the abnormal humidity in the lower part of the test block 3. If no abnormality is found in the waterproof membrane, the humidity detection mechanism will not detect much change. When it is necessary to terminate the water tightness test, the water inlet and outlet components can continue to operate to draw out the water in the cavity. Then, the linear drive component 105 is operated to drive the sealing ring 101 to disengage from the test block 3. Then, the operator removes the test block 3 from the placement slot and replaces it.

[0028] Furthermore, the water inlet and outlet assembly includes a water storage tank 102, a forward and reverse water pump 108, a first water pipe 109, and a second water pipe 104. The water storage tank 102 has an opening at its upper part, and a detachable cover plate is provided on the opening. The cover plate has a through hole, and the first water pipe 109 passes through the through hole. One end of the first water pipe 109 is located inside the water storage tank 102, and the other end of the first water pipe 109 is connected to one end of the forward and reverse water pump 108. The other end of the forward and reverse water pump 108 is connected to the upper part of the telescopic pipe 107 through the second water pipe 104, and the second water pipe 104 is fixedly connected to the frame 2.

[0029] As can be seen from the above description, after the sealing ring 101 is pressed on top of the test block 3, the forward and reverse water pump 108 can be run to pump water from the water storage tank 102 into the second water pipe 104 through the first water pipe 109, and then into the telescopic pipe 107. The water in the telescopic pipe 107 is used to conduct a water tightness test on the test block 3. After the water tightness test is completed, the forward and reverse water pump 108 can continue to run to pump water from the telescopic pipe 107 into the water storage tank 102 through the second water pipe 104 for collection. Then the connection between the sealing ring 101 and the test block 3 can be disconnected.

[0030] Furthermore, the humidity detection mechanism includes a moisture-absorbing cotton pad 7 and a humidity detector 6. The bottom of the placement groove is provided with an installation groove 5 that is compatible with the humidity detector 6. The humidity detector 6 is installed inside the installation groove 5. A limiting platform is provided on the upper part of the installation groove 5. The moisture-absorbing cotton pad 7 is laid on the limiting platform. The top surface of the moisture-absorbing cotton pad 7 is in contact with the test block 3, and the bottom surface of the moisture-absorbing cotton pad is in contact with the detection probe of the humidity detector 6.

[0031] As can be seen from the above description, when there is an abnormality in the waterproof film on test block 3, water can penetrate through test block 3 to the moisture-absorbing cotton pad 7, and then be detected by the humidity detector 6 to detect the abnormal humidity, thereby detecting the abnormality of the waterproof coating. When it is necessary to test the next test block 3, a new moisture-absorbing cotton pad 7 can be replaced, thus making the test more accurate.

[0032] Furthermore, the sealing ring 101 includes a ring body 1011 and a sealing ring 1012. The ring body 1011 is connected to the lower part of the telescopic tube 107, the upper surface of the ring body 1011 is connected to the connecting rod 106, and the lower surface of the ring body 1011 is provided with a sealing ring 1012 groove, and the sealing ring 1012 is disposed inside the sealing ring 1012 groove.

[0033] As can be seen from the above description, it is beneficial for the linear drive component 105 to move the ring body 1011 through the connecting rod 106, so that the ring body 1011 is pressed on the test block 3, and the sealing ring 1012 seals the ring body 1011 around, preventing water from overflowing from the ring body 1011 after water is poured into the telescopic tube 107.

[0034] Furthermore, the test block 3 is T-shaped.

[0035] As can be seen from the above description, when it is necessary to replace the test block 3, the test block 3 can be taken out from the placement slot through both ends of the T-shaped test block 3.

[0036] Furthermore, the frame 2 is provided with a sliding hole adapted to the connecting rod 106, and the connecting rod 106 is slidably connected to the inside of the sliding hole.

[0037] As can be seen from the above description, it is beneficial for the connecting rod 106 to slide inside the sliding hole, making the lifting and lowering of the ring 1011 more stable, and making the sealing ring 1012 better pressed on the test block 3.

[0038] Furthermore, it also includes a PLC controller, which is electrically connected to the water-sealing mechanism 1 and the humidity detection mechanism respectively.

[0039] As can be seen from the above description, it is beneficial to adjust the parameters of the waterproof coating effect testing equipment through the PLC controller, and it makes it more convenient for operators to operate the waterproof coating effect testing equipment. Example 1
