Description

Technical Field

[0001] This utility model belongs to the field of coating anti-corrosion technology, and in particular relates to a marine environment steel structure coating anti-corrosion test device. Background Technology

[0002] Currently, the corrosion resistance testing of steel structure coatings in marine environments mostly uses salt spray corrosion or static immersion methods. However, in actual marine environments, coatings are not only affected by salt spray deposition but also subjected to periodic wave impacts. Under repeated scouring, the coating surface is more prone to peeling, cracking, or failure. Therefore, existing single salt spray test chambers cannot fully reflect the durability of coatings under wave impacts. At the same time, the brine after impact is often directly discharged during the test, which not only wastes resources but also hinders the collection and analysis of coating flaking material, lacking means for recycling and detecting the amount of coating flaking. Utility Model Content

[0003] This invention provides a marine environment steel structure coating anti-corrosion test device, which aims to solve the problem that the existing single salt spray test chamber cannot fully reflect the durability of the coating under the impact of sea waves. At the same time, the salt water after the impact is often directly discharged during the test, which not only wastes resources, but also makes it difficult to collect and analyze the coating peeling material.

[0004] This utility model is implemented as follows: a marine environment steel structure coating anti-corrosion test device, comprising: a base plate and a drainage pipe, a support frame fixedly connected to the base plate, a salt spray chamber and a test chamber installed on the support frame, a simulation device installed inside the test chamber, and a filter device fixedly connected to the base plate; The simulation device includes a water tank and a connecting plate. A water pump is installed in the water tank, and a pipe is installed at the output end of the water pump. Two mounting plates are fixedly connected to the connecting plate. A fixed shaft is fixedly connected inside the mounting plate. A collar is fitted around the fixed shaft. A rotating plate is fixedly connected to the collar. A water storage box is fixedly connected to the rotating plate.

[0005] Preferably, the simulation device further includes two push rods, which are symmetrically mounted on the upper surface of the connecting plate, and the push rods are set to an inclined state.

[0006] Preferably, a partition is fixedly connected inside the water storage box, and the water storage box overlaps the upper surface of one of the top rods.

[0007] Preferably, the fixed shaft and the collar form a rotatable connection.

[0008] Preferably, the filter device includes a housing, and a support rod is fixedly connected to the bottom of the housing, the support rod being fixedly connected to the base plate.

[0009] Preferably, the drain pipe is connected through the test chamber and is located above the chamber.

[0010] Preferably, a filter plate is installed inside the tank, and a water outlet pipe is installed at the bottom of the tank, with the water outlet pipe positioned above the water tank.

[0011] Compared with related technologies, the marine environment steel structure coating anti-corrosion test device provided by this utility model has the following beneficial effects: 1. In this utility model, when the water pump starts, the brine in the water tank is drawn and injected into the water storage box through the pipeline. When the water volume in the water storage box gradually increases to a certain weight, the unstable support of the water storage box on the top rod causes the water storage box to rotate around the fixed shaft under the action of gravity. Finally, the water storage box tilts to one side, and the brine is instantly splashed onto the surface of the steel structure coating in the test chamber, realizing the process of simulating the impact of sea waves on the coating. This operation mode can periodically reproduce the impact effect of sea waves on the coating, making the test closer to the corrosion conditions in the real marine environment.

[0012] 2. In this utility model, by installing a drain pipe above the test chamber, the impacted brine is discharged in time and introduced into the chamber below. When the brine is filtered by the filter plate, it can effectively intercept the coating debris washed off, completing the collection and analysis of the coating peeling material. At the same time, the brine purified by the filter plate flows back into the water tank through the outlet pipe, realizing the recycling of brine. This operation mode not only avoids the waste of brine, but also allows for further analysis of coating failure by observing and statistically analyzing the filter residue, thereby improving the practicality and environmental friendliness of the test device.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0015] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0016] This utility model embodiment provides a marine environment steel structure coating corrosion protection testing device, such as... Figure 1-4 As shown, it includes a base plate 1 and a drain pipe 7. A support frame 2 is fixedly connected to the base plate 1. A salt spray chamber 3 and a test chamber 4 are installed on the support frame 2. A simulation device 5 is installed inside the test chamber 4. A filter device 6 is fixedly connected to the base plate 1. The simulation device 5 includes a water tank 501 and a connecting plate 504. A water pump 502 is installed inside the water tank 501. A pipe 503 is installed at the output end of the water pump 502. Two mounting plates 505 are fixedly connected to the connecting plate 504. A fixed shaft 506 is fixedly connected inside the mounting plate 505. A collar 507 is provided outside the fixed shaft 506. A rotating plate 508 is fixedly connected to the collar 507. A water storage box 509 is fixedly connected to the rotating plate 508.

[0017] In this embodiment, the fixed shaft 506 and the collar 507 form a rotatable connection, which allows the collar 507 to rotate flexibly outside the fixed shaft 506. This avoids the jamming phenomenon that occurs when the water storage box 509 increases in water volume, thereby ensuring that the water storage box 509 can be tilted smoothly when it reaches the critical weight, and improving the stability and reliability of the simulated wave impact process.

[0018] In a further preferred embodiment of the present invention, the simulation device 5 further includes two push rods 511, which are symmetrically installed on the upper surface of the connecting plate 504. The push rods 511 are set in an inclined state. A partition plate 510 is fixedly connected inside the water storage box 509. The water storage box 509 overlaps the upper surface of one of the push rods 511. The fixed shaft 506 and the collar 507 form a rotatable connection.

[0019] In this embodiment, the partition 510 is fixed inside the water storage box 509, which can separate and buffer the brine entering the water storage box 509, and prevent the brine from prematurely triggering the tilting action due to shaking during the injection process, thereby ensuring that the tilting occurs after the water volume reaches the set weight, and improving the accuracy of the impact simulation.

[0020] In a further preferred embodiment of this utility model, the filter device 6 includes a housing 601, a support rod 602 fixedly connected to the bottom of the housing 601, the support rod 602 fixedly connected to the bottom plate 1, a drain pipe 7 penetrating and connected inside the test chamber 4, the drain pipe 7 being above the housing 601, a filter plate 603 installed inside the housing 601, and a water outlet pipe 604 installed below the housing 601, the water outlet pipe 604 being above the water tank 501.

[0021] In this embodiment, the filter plate 603 and the outlet pipe 604 are arranged vertically. When the brine flows through the filter plate 603, it can effectively trap coating debris. The purified liquid then flows back to the water tank 501 through the outlet pipe 604, realizing a continuous process of brine purification and recycling, thereby improving the feasibility of recycling.

[0022] In summary, when the water pump 502 starts, the brine in the water tank 501 is drawn and injected into the water storage box 509 through the pipe 503. When the water volume in the water storage box 509 gradually increases to a certain weight, the unstable support of the water storage box 509 on the top rod 511 causes the water storage box 509 to rotate around the fixed shaft 506 under the action of gravity, which drives the rotating plate 508 and the collar 507. Finally, the water storage box 509 tilts to one side, instantly splashing the brine onto the steel structure coating surface in the test chamber 4. By setting the drain pipe 7 above the test chamber 4, the impacted brine is discharged in time and introduced into the lower chamber 601. When the brine is filtered by the filter plate 603, it can effectively intercept the coating debris washed down, completing the collection and analysis of the coating peeling material. At the same time, the brine purified by the filter plate 603 flows back to the water tank 501 through the outlet pipe 604, realizing the recycling of brine.
