The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0019] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses an automatic immersion testing device for testing the water resistance of coatings, comprising a water tank 1 and multiple plates 2 coated with coating to be tested. A support plate 4 is installed on one side of the water tank 1, and a main pipe 6 is provided on the inner side of the support plate 4. Multiple drip heads 7 are threadedly connected to the side of the main pipe 6 facing the water tank 1. A baffle 3 is installed inside the water tank 1. The plates 2 are inclinedly placed inside the water tank 1, with one end of the plates 2 in contact with the baffle 3 and the other end placed on the inner side of the support plate 4. A drive mechanism for moving the main pipe 6 back and forth is installed on the outer surface of the support plate 4. A water circulation mechanism is installed between the water tank 1 and the main pipe 6.

[0021] In this embodiment, the driving mechanism includes a telescopic cylinder 8 and a connecting seat 9. The support plate 4 is arranged in an "L" shape. The upper surface of the support plate 4 is provided with a strip-shaped opening 10 opposite to the main pipe 6. One end of the connecting seat 9 passes through the strip-shaped opening 10 and is installed on the main pipe 6. The telescopic cylinder 8 is installed on the upper surface of the support plate 4. The piston rod of the telescopic cylinder 8 is fixedly connected to the other end of the connecting seat 9. A fixing frame is installed on the outside of the telescopic cylinder 8. Both ends of the fixing frame are installed on the support plate 4.

[0022] In this embodiment, the water circulation mechanism includes a circulation pump 12, an inlet pipe 13, an outlet pipe 14, and a hose 11. The inlet pipe 13 is installed at one end of the water tank 1. The pumping end of the circulation pump 12 is installed on the inlet pipe 13. The hose 11 is installed on the outlet end of the circulation pump 12. The other end of the hose 11 is fixedly connected to the outlet pipe 14. The other end of the outlet pipe 14 is installed on the main pipe 6. The hose avoids limiting the main pipe and can pull the hose during the movement of the main pipe. A filter screen is installed in the inlet pipe to intercept impurities in the water.

[0023] In this embodiment, a drain pipe 15 is installed on one side of the water tank 1, and a valve 16 is installed on the drain pipe 15. When it is necessary to drain the water inside, the valve can be opened so that the water inside the water can be drained through the drain pipe, which facilitates the replacement of the water inside.

[0024] In this embodiment, U-shaped frames 5 are fitted at both ends of the main pipe 6. One end of the U-shaped frame 5 is installed on the support plate 4. A positioning port is formed between the U-shaped frame 5 and the support plate 4. The length and width of the positioning port match the length and width of the main pipe 6 cross section. The main pipe can be positioned by the U-shaped frame, so that the main pipe can only move back and forth through the positioning port.

[0025] In this embodiment, the dripper 7 is positioned vertically toward the board 2, so that the water droplets generated by the dripper can fall vertically onto the board, increasing the smoothness of the dripping.

[0026] When in use, the coated board is placed at an angle underwater, with one end of the water tank resting against the baffle and the other end against the support plate.

[0027] After the above is completed, pour clean water into the water tank so that half of the board is submerged. Start the circulation pump to draw out the clean water from the water tank and inject it into the main pipe through the hose and the outlet pipe until it drips from the dripper. The water droplets produced by the dripper can drip onto the other half of the board, so that one half of the board is submerged and the other half simulates the external rain.

[0028] When water is dripping, the telescopic cylinder can be activated, causing the piston rod of the telescopic cylinder to continuously extend and retract. The movement of the piston rod drives the connecting seat, which in turn pushes the main pipe, causing the main pipe to continuously move back and forth along the positioning port and the strip port to change the position of the dripper and the water droplet. This can better simulate the external environment and thus increase the test quality.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
