Water resistance is an important indicator of paint performance, directly affecting the service life and effect of the paint. According to relevant technical specifications, when measuring, 2 / 3 of the three test panels coated with the paint to be tested need to be immersed in distilled water or deionized water, and then taken out and observed after a specified time.

The device includes a water faucet, a deionized water supply device, an inner water tank, an outer water tank, and an inclined plate. The inner water tank is arranged inside the outer water tank, and the outer wall of the inner water tank is provided with a plurality of inner water tank drainage holes. The inner water tank is provided with an inclined plate for placing experimental test panels. The deionized water supply device is connected to the water faucet through a water pipe to transmit deionized water to the test panels. This scheme uses a water faucet above the test panels to transmit deionized water, which can test the water resistance of the paint to be tested using both immersion and dripping methods.

[0004] However, the above-mentioned scheme requires placing the test panels on the inclined plate, which results in a fixed angle between the surface of the test panel and the direction of water droplets, limiting the simulation of rainfall scenarios. Utility model content

[0005] The utility model intends to provide a waterproof coating water resistance detection device to solve the problem of limited simulation of rainfall scenarios in the above-mentioned scheme.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A waterproof coating water resistance detection device includes a detection box, a movable frame, a displacement mechanism, and a water circulation mechanism. The top of the detection box is open, and a support rod is fixedly arranged in the detection box along the transverse direction. N dripping pipes are also arranged at intervals on the right side of the support rod in the detection box. The bottom of each dripping pipe is provided with a plurality of through dripping holes at intervals in the detection box. The movable frame is movably arranged below the support rod in the detection box, and the top of the movable frame is fixedly provided with N limiting grooves arranged along the transverse direction. The displacement mechanism is arranged in the detection box to drive the movable frame to move left and right. The water circulation mechanism includes a water return pipe. The inlet end of the water return pipe is connected to the inside of the detection box below the movable frame, and the outlet end of the water return pipe is connected to each dripping pipe. N is a natural number that is 3 times an integer.

[0008] The principles and effects of the technical scheme are as follows:

[0009] During detection, N test plates are inserted between two adjacent drip pipes or between the drip pipes and the supporting rods with the paint-coated side facing upwards, and the bottom of each test plate is inserted into the corresponding limiting groove, then the displacement mechanism is driven to move the movable frame left and right until the angle between the test plate and the horizontal plane reaches the predetermined angle, distilled water or deionized water is added into the detection box so that the water covers 2 / 3 of the test plate, then the water in the detection box flows into each drip pipe through the backwater pipe and flows out through the drip holes at the bottom of each drip pipe, and finally drops onto the surface of the test plate exposed to the water surface.

[0010] Through the above arrangement, the movable frame arranged in the detection box is used to rotate the test plate and adjust the angle between the test plate and the vertical plane, so that the device can simulate rainfall conditions in various scenarios, and the land area occupied by the device is saved.

[0011] In the utility model, the front and rear two inner side walls of the detection box are fixedly provided with guide rails along the transverse direction, the front and rear ends of the movable frame are slidably sleeved with the corresponding guide rails, the displacement mechanism comprises a lead screw rotatably arranged in the detection box along the vertical direction, and a sliding block sleeved with the lead screw, a connecting rod is rotatably connected to the right side wall of the sliding block, one end of the connecting rod is rotatably connected to the left side wall of the movable frame, and the left side wall of the sliding block slidably abuts against the inner side wall of the detection box.

[0012] The principles and effects of the technical scheme are as follows:

[0013] The lead screw is rotated, the inner side wall of the detection box limits the rotation of the sliding block, and the sliding block moves up and down with the rotation of the lead screw, and when the sliding block moves up and down, the connecting rod can pull the movable frame to move left and right.

[0014] Through the above arrangement, the purpose of driving the displacement mechanism to move the movable frame left and right is achieved.

[0015] In the utility model, the water circulation mechanism further comprises a water pump, and the water pump is fixedly arranged in the detection box below the movable frame and communicates with the inlet end of the backwater pipe.

[0016] In the utility model, the water circulation mechanism further comprises a water valve communicated between the backwater pipe and each drip pipe.

[0017] Through the above arrangement, the purpose of conveying the water in the detection box from the backwater pipe to each drip pipe is achieved, and the water valve can also be adjusted to adjust the amount of water flowing out of the drip holes per unit time, further widening the application scenarios of the device.

[0018] In this invention, a heating tube is horizontally fixed inside the testing chamber between the movable frame and the water pump. This design allows for the heating of the distilled or deionized water inside the testing chamber to meet the testing requirements.

[0019] In this invention, a filter screen is fixedly installed laterally between the movable frame and the water pump inside the testing box. This design prevents paint detached from the test plate surface from clogging the water pump, thus extending the service life of the device.

[0020] In this invention, the bottom of the inner wall of the testing box is provided with a through hole extending to the outer wall of the testing box, and a plug is threaded into the through hole. This design facilitates the drainage of water from the testing box, improving the practicality of the device. Attached Figure Description
