Description

Technical Field

[0001] The present invention relates to the technical field of anti-corrosion testing, and particularly to a device for testing the anti-corrosion performance of a water-based zinc-aluminum coating for a marine junction box. Background Art

[0002] In order to ensure the stability of the junction box in marine applications, a water-based zinc-aluminum coating is usually applied to its surface. As an innovative metal anti-corrosion coating technology, the water-based zinc-aluminum coating can significantly improve the corrosion resistance of the junction box. After the application of the water-based zinc-aluminum coating, an anti-corrosion performance testing device is required to strictly test the anti-corrosion performance of the junction box. This step can not only verify the coating effect but also detect the coating uniformity of the junction box.

[0003] When the existing anti-corrosion performance testing devices perform testing tasks, they generally tend to use spraying as the main testing method. Although the design of the spray nozzles has strived to achieve coverage without dead angles, in actual operation, there are still blind spots where the spraying liquid cannot be fully covered in the area of close contact between the junction box and the testing station. This situation directly leads to the fact that some local positions of the junction box cannot be effectively tested, thus affecting the comprehensiveness and accuracy of the testing. Summary of the Invention

[0004] Embodiments of the present disclosure relate to a device for testing the anti-corrosion performance of a water-based zinc-aluminum coating for a marine junction box. By setting two sets of support and bearing structures for the junction box body, namely support base A and support base B, the use of the two support and bearing structures alternately can change the bearing fulcrum for the junction box body during the spraying test, so that all positions of the butted box body are in contact with the spraying liquid, ensuring the comprehensiveness and accuracy of the anti-corrosion performance test of the coating, and preventing the problem that there are local positions of the junction box body that cannot be tested due to the inconvenient fixed fulcrum position of the junction box body.

[0005] In the first aspect of the present disclosure, a device for testing the anti-corrosion performance of an aqueous zinc-aluminum coating for a marine junction box is provided, specifically including: a test box body, with a pick-and-place window opened at the top of the test box body; a sealing cover plate rotatably installed at the rear side of the top of the test box body; a water supply pipeline fixedly installed inside the test box body; guide slide bars fixedly installed on the left and right sides inside the test box body; a support seat A sleeved and slidably installed on the guide slide bars; force-receiving plates fixedly installed on the front and rear sides of the bottom of the support seat A; a switching lead screw rotatably installed on each of the front and rear sides inside the test box body; a sprocket fixedly installed at the right end of each of the two switching lead screws; a guide seat fixedly installed at the bottom end inside the test box body; a guide slide plate slidably installed on the guide seat; a limiting block fixedly installed on the outer side of the guide slide plate; a support seat B fixedly installed on the top of the guide slide plate; driven plates fixedly installed on the front and rear sides of the support seat B; a driven groove opened at the inner end of the inner side of the driven plate; a horizontal groove opened at the outer end of the inner side of the driven plate; a switching slider installed on the switching lead screw through screw threads; a transmission plate fixedly installed on the inner side of the switching slider; and a transmission column fixedly installed at the top end of the outer side of the transmission plate.

[0006] In at least some embodiments, a switching motor is fixedly installed at the bottom left of the test box body; a discharge pipeline is fixedly installed at the bottom rear of the test box body; an observation window is opened at the front side of the test box body; there is an insertion interface on each of the left and right sides at the bottom of the water supply pipeline; and a water inlet is provided at the top right of the water supply pipeline.

[0007] In at least some embodiments, an atomizing nozzle is fixedly installed on the water supply pipeline; the support seat A is in a U-shaped structure; and a spring A is jointly embedded between the outer side of the support seat A and the inner side wall of the test box body.

[0008] In at least some embodiments, the force-receiving plate is in an L-shaped structure; two opposite screw threads are arranged in a left-right symmetric manner on the circumferential outer wall of the switching lead screw; the left end of the switching lead screw located at the front side is connected to the output shaft of the switching motor; and the two sprockets are connected by a chain.

[0009] In at least some embodiments, the support seat B is in a U-shaped structure; a connecting seat is fixedly installed at the bottom of the support seat B; a movable pipeline is fixedly installed on the connecting seat; a movable nozzle is fixedly installed on the movable pipeline; and a docking slide pipe is fixedly installed at each of the left and right ends of the top of the movable pipeline, and the docking slide pipe is also slidably installed in the two insertion interfaces at the bottom end of the water supply pipeline.

[0010] In at least some embodiments, a spring B is jointly embedded between the top end of the movable pipeline and the bottom end of the water supply pipeline; the driven groove is of an inclined structure; the inner end of the horizontal groove communicates with the lowest end of the driven groove; a mounting member is fixedly installed at the front end of the switching slider located on the front side.

[0011] In at least some embodiments, the transmission column is of a cylindrical structure; the transmission column is also slidably installed in a conversion groove composed of a driven groove and a horizontal groove; a pressing slide column is slidably installed on the front side of the mounting member; a pressing slide plate is fixedly installed at the front end of the pressing slide column.

[0012] In at least some embodiments, a spring C is jointly embedded between the rear side of the pressing slide plate and the front side of the mounting member; a cleaning wiping pad is fixedly installed at the front end of the pressing slide plate; a wiring box body is placed on the support seat A; when the switching lead screw rotates, it will drive two groups of switching sliders and two groups of transmission plates to slide relatively outward.

[0013] In at least some embodiments, when the transmission plate slides outward, the transmission column on the transmission plate will use the inclined structure of the driven groove to drive the driven plate and two support seats B to move upward; after the two support seats B come into contact with the bottom of the wiring box body by moving upward, when the transmission plate continues to slide outward, it will push the stress plate outward.

[0014] In at least some embodiments, after the stress plate receives an outward pushing force, it will drive the support seat A to move outward along the guiding slide rod; after the support seat A moves outward, it will cancel the bearing support for the wiring box body; the cleaning wiping pad also frictionally contacts the observation window; when the switching slider moves outward, it will also drive the pressing slide plate and the cleaning wiping pad to slide outward.

[0015] The present invention provides a device for testing the anti-corrosion performance of a water-based zinc-aluminum coating for a marine wiring box, which has the following beneficial effects: First, by introducing two sets of support and bearing structures, namely support seat A and support seat B, specifically designed for the wiring box body and flexibly alternating their use during the spray test, the position of the support points of the wiring box body can be effectively changed. This design ensures that all parts of the wiring box body can fully contact the spray liquid, thus greatly improving the comprehensiveness and accuracy of the coating anti-corrosion performance test and avoiding the problem that some areas of the wiring box body cannot be tested due to the fixed position of the support points.

[0016] Second, when the present invention uses the switching lead screw to switch the support points, it can also achieve the synchronous translation of the switching slider driving the pressing slide plate and the cleaning wiping pad. During this process, the cleaning wiping pad can automatically wipe and clean the observation window to ensure that the observation window remains clear, facilitating the staff to clearly observe and understand the test progress of the wiring box body inside the device.
