[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Refer to Figures 1-3, A paint waterproof performance detection device of the utility model includes a base 1. There is a water receiving tank 13 inside the base 1. A water storage base 2 is movably arranged on the base 1. A water storage cylinder 3 communicating with the water receiving tank 13 is arranged on the water storage base 2. A detection cloth 14 is arranged between the water storage cylinder 3 and the water receiving tank 13. Pressurizing cylinders 4 are arranged on both sides of the water storage cylinder 3 on the water storage base 2. The water storage cylinder 3 is communicated with the pressurizing cylinders 4 through a connecting pipe 10. A piston plate 15 is arranged inside the pressurizing cylinder 4. The base 1 and the water storage base 2 are connected by a fastener 6.

[0027] One end of the connecting pipe 10 is located at a position near the bottom of the water storage cylinder 3 and above the detection cloth 14, and the other end is connected to the bottom of the pressurizing cylinder 4. Since in the natural state, the liquid pressure is mainly related to the depth, by adjusting the liquid level height in the water storage cylinder 3 through the pressurizing cylinder 4, the pressure on the detection cloth 14 and the waterproof coating layer can be effectively changed. The piston plate 15 is slidably and sealingly connected to the inner wall of the pressurizing cylinder 4. When in use, an appropriate amount of water is injected into the water storage cylinder 3 to meet the requirement of the minimum test pressure, and then the pressurizing cylinder is adjusted to raise the water surface in the water storage cylinder 3 to different heights to detect the waterproof performance of the waterproof coating at the corresponding liquid level heights.

[0028] The inner diameter size of the pressurizing cylinder 4 is larger than the inner diameter size of the water storage cylinder 3.

[0029] When adjusting the position of the piston plate 15, when the piston plate 15 moves a specified distance, the liquid level in the water storage cylinder 3 rises a greater distance, which is convenient for meeting the requirements by shortening the moving distance of the piston plate 15 and reducing the workload of manual operation.

[0030] A screw rod 5 is screwed on the pressurizing cylinder 4. One end of the screw rod 5 is rotatably connected to the piston plate 15, and the other end is provided with a disc handle.

[0031] Specifically, by rotating the screw rod 5 through the disc handle to drive the piston plate 15 to move, similar to the lever principle, the labor intensity of workers can be effectively reduced. At the same time, taking advantage of the high precision of screw transmission, it is convenient to accurately control the change of the liquid level height in the water storage cylinder 3, so as to accurately detect the waterproof performance of the waterproof coating under different water pressures.

[0032] There is an annular step groove at the top of the water receiving tank 13. A receiving plate 9 is movably arranged in the step groove. The receiving plate 9 is uniformly provided with water permeable holes. A detection cloth 14 is arranged on the top of the receiving plate 9.

[0033] The water permeable holes penetrate through the receiving plate 9. The function of the receiving plate 9 is to prevent the detection cloth 14 from being severely deformed when under water pressure, resulting in cracks in the coating and affecting the detection.

[0034] An anhydrous copper sulfate coating is coated on the top end face of the receiving plate 9. The detection cloth 14 is covered on the anhydrous copper sulfate coating.

[0035] Anhydrous copper sulfate turns blue when it comes into contact with water. By observing the color change of the anhydrous copper sulfate coating, it is possible to confirm whether there is a trace amount of water that is not easily observable by the human eye seeping out from the bottom of the test cloth 14, further improving the detection accuracy of the waterproof performance of the coating by this device.

[0036] The water receiving tank 13 is a sunken tank structure with an open top, and a desiccant packet 8 is arranged inside the water receiving tank 13.

[0037] The desiccant packet 8 can be filled with magnesium chloride desiccant. When a large amount of water seeps out from the bottom of the test cloth 14 and flows into the water receiving tank 13 through the water permeable holes, the desiccant packet 8 can absorb the water in the water receiving tank 13. At the end of the test, the desiccant packet 8 can be directly taken out, and there is no need to clean the water receiving tank 13 separately.

[0038] During the test, the test cloth 14 is pressed tightly on the top of the receiving plate 9. Annular sealing rings are installed at the bottom of the stepped groove and the water storage cylinder 3 to form a sealed environment inside the water storage cylinder 3, preventing the desiccant packet 8 from absorbing the water vapor in the external environment of the base 1 and ensuring the water absorption effect of the desiccant packet 8.

[0039] The fastener 6 includes a conical platform 11 arranged on the top of the base 1. A bolt is arranged on the top of the conical platform 11, and a wing nut 12 is arranged on the bolt. A conical groove corresponding to the conical platform 11 is opened on the water storage base 2, and a through hole is opened at the top of the conical groove. The bolt is inserted through the through hole.

[0040] Both the conical platform 11 and the conical groove are structures with a smaller top and a larger bottom, which is convenient for installing the water storage base 2 on the base 1 by the cooperation of the conical groove and the conical platform 11. After the conical groove and the conical platform 11 are fitted together, the water storage cylinder 3 is aligned with the water receiving tank 13. Then, the wing nut 12 is screwed onto the bolt to press the water storage base 2, and the test cloth 14 and the receiving plate 9 are pressed tightly on the top of the water receiving tank 13.

[0041] A liquid level gauge 7 is arranged on one side of the water storage cylinder 3.

[0042] The bottom of the liquid level gauge 7 is communicated with the connecting pipe 10. The liquid level gauge 7 is made of a transparent plastic pipe. By observing the liquid level height inside the liquid level gauge 7, the liquid level height inside the water storage cylinder 3 can be confirmed.

[0043] The base 1 and the water storage base 2 are made of transparent materials.

[0044] The transparent material can be selected as transparent plastic or tempered glass, which is convenient for directly observing the water seepage situation inside the water receiving tank 13 without removing the water storage base 2.

[0045] Working principle: When in use, spread the detection cloth 14 on the receiving plate 9, apply waterproof coating on the top surface of the detection cloth 14, then align the conical groove with the conical platform 11, install the water storage seat 2 on the base 1, tighten the butterfly nut 12, compress the detection cloth 14, fill water into the water storage cylinder 3, and after standing for a specified time, observe whether the desiccant bag 8 in the water receiving tank 13 is damp to judge the water seepage. If no water seepage is found under low pressure, the screw 5 can be turned to raise the liquid level in the water storage cylinder 3, and then stand for a specified time, and gradually observe the water seepage in the water receiving tank 13 under different water pressures. If no water seepage is found, after the water in the water storage cylinder 3 is extracted and the water storage seat 2 is removed, it can be observed whether the anhydrous copper sulfate on the surface of the receiving plate 9 changes color to prevent the situation where trace water seepage is not easy to be observed and missed.
