Description

Technical Field

[0001] The invention belongs to the technical field of coating detection, and in particular relates to a dynamic detection device and a detection method for anti-corrosion coatings. Background Art

[0002] Anticorrosive coatings are an essential type of paint and are mainly used to protect materials such as metals and concrete from corrosion. They effectively prevent metals from rusting and corroding by forming a dense protective film on the surface of the material to prevent the penetration of moisture, oxygen and corrosive substances. Anticorrosive coatings can generally be divided into conventional anticorrosive coatings and heavy anticorrosive coatings.

[0003] After the development of anti-corrosion coatings is completed, it is crucial to evaluate their performance. One commonly used evaluation method is to apply the coating to a specific substrate (such as a metal plate) and then immerse the coated substrate in salt water. After a period of time, the performance of the coating is evaluated by checking the anti-corrosion effect of the substrate.

[0004] However, this method has an obvious limitation, that is, it simulates a static water environment, which is very different from the dynamic environment of water flow in actual applications. Therefore, the results obtained by this static evaluation method cannot fully and objectively reflect the performance of anti-corrosion coatings in actual applications. In addition, most devices adopt a fixed method when placing the substrate, and cannot adjust the angle as needed to simulate the diversity of the actual working environment. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a dynamic detection device and detection method for anti-corrosion coatings, which has the advantages of dynamically detecting anti-corrosion coatings and being able to adjust the angle of the substrate, thereby solving the problems existing in the prior art.

[0008] As a preferred embodiment of the present invention, the dynamic detection component includes a first liquid circulation pipeline, one end of the first liquid circulation pipeline is installed inside the detection box, and the other end of the first liquid circulation pipeline is installed outside the detection box; One end of the first liquid circulation pipeline is fixedly connected with a nozzle, and the nozzle is located inside the detection box.

[0009] As a preferred embodiment of the present invention, a liquid storage tank is installed at the bottom of the detection box, one end of the first liquid circulation pipe is fixedly connected to one side of the liquid storage tank, and the first liquid circulation pipe can be interconnected with the liquid storage tank.

[0010] As a preferred embodiment of the present invention, a plurality of first fixed plates are fixedly connected to the back of the first disc, each of the first fixed plates is provided with a first spring, one end of the first spring is fixedly connected to the first fixed plate, the other end of the first spring is fixedly connected to a support plate, each of the support plates is fixedly connected to a first support frame, and a rolling roller is rotatably connected in the first support frame.

[0011] As a preferred embodiment of the present invention, a third opening groove is provided on the upper side of the liquid storage tank; A first airbag is installed in the third opening slot, the upper half of the first airbag extends into the detection box, the lower half of the first airbag extends into the liquid storage box, and two sides of the first airbag are fixedly connected to the edges of the third opening slot; A second airbag is installed at the lower side of the first airbag, the second airbag is located in the liquid storage tank, and two sides of the second airbag are fixedly connected to the liquid storage tank.

[0012] As a preferred embodiment of the present invention, two symmetrical second support frames are fixedly connected to the upper side of the liquid storage tank, the second support frames are respectively located on both sides of the first airbag, and a second spring is fixedly connected between the second support frame and the first airbag.

[0013] As a preferred embodiment of the present invention, two symmetrical first slideways are provided in the second opening groove, electric sliders are slidably connected in the first slideways, and an arc-shaped baffle is fixedly connected between the two electric sliders.

[0014] A dynamic detection method for anti-corrosion coatings comprises the following steps: Step S1, evenly applying the anti-corrosion coating on the substrate; Step S2, sending the substrate into the installation groove through the first opening groove and the second opening groove; Step S3, the dynamic detection component sprays a specific liquid, and the liquid contacts the surface of the substrate on the first disc, and then interacts with the anti-corrosion coating on the substrate, so as to detect the performance of the anti-corrosion coating; Step S4, the angle adjustment component drives the substrate to adjust the angle via the first disc.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When testing the performance of anti-corrosion coatings, first, ensure that the anti-corrosion coating is evenly applied on the specified substrate. Then, to evaluate the performance of the material, the substrate needs to pass through a preset path, first entering the first opening slot connected to the test box, and then entering the installation slot through the second opening slot.

[0016] After the substrate enters the installation slot, the dynamic detection component is activated, which releases a specific liquid. This liquid will directly contact the surface of the substrate on the first disc, and then react with the anti-corrosion coating on the substrate to detect its performance.

[0017] If the substrate angle needs to be adjusted to achieve a more comprehensive inspection, the angle adjustment component will be activated to drive the first disc to rotate. Since the substrate is firmly fixed on the first disc, it will rotate synchronously with the disc to achieve angle adjustment. During this process, the dynamic detection component will continue to spray liquid to ensure that all angles of the substrate can be effectively inspected to ensure the comprehensiveness and accuracy of the inspection results.

DETAILED DESCRIPTION

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0022] See also Figures 1 to 8 A dynamic detection device for anti-corrosion coatings provided by an embodiment of the present invention includes a detection box 1, a first opening groove 14 is opened on the upper side of the detection box 1, a first disc 11 is arranged in the detection box 1, a second opening groove 12 is opened on the upper side of the first disc 11, a mounting groove 13 is opened in the first disc 11, and the second opening groove 12 is connected to the mounting groove 13; an angle adjustment component is installed on one side of the first disc 11; and a dynamic detection component is installed on the other side of the first disc 11.

[0023] The above scheme is adopted: when in use, in the actual operation of anti-corrosion coating detection, first, the anti-corrosion coating is evenly applied on the substrate. When the performance of these anti-corrosion coatings needs to be evaluated, the substrate is sent into the first opening slot 14, which is connected to the detection box 1, so that the substrate can enter the detection box 1. Then, the substrate is continued to be sent into the second opening slot 12, which is connected to the installation slot 13, so that the substrate is directly sent into the installation slot 13.

[0024] After the substrate enters the installation groove 13, the dynamic detection component sprays a specific liquid. The liquid contacts the surface of the substrate on the first disc 11 and then interacts with the anti-corrosion coating on the substrate, thereby detecting the performance of the anti-corrosion coating.

[0025] If the angle of the substrate needs to be adjusted for more comprehensive testing, the angle adjustment component drives the first disc 11 to rotate. Since the substrate is fixed on the first disc 11, the substrate will rotate with the rotation of the first disc 11, thereby achieving the angle adjustment of the substrate. During this process, the dynamic detection component will continue to spray liquid to ensure that the surface of the substrate can be covered by liquid at any angle, thereby achieving efficient and comprehensive anti-corrosion coating performance testing.

[0026] It should be noted that the liquid sprayed from the dynamic detection component is salt water, which can be replaced by other types of liquids according to actual needs. For example, when it is necessary to test the reaction of the anti-corrosion coating to an acidic environment, an acidic solution can be used; and when it is necessary to simulate an alkaline environment, an alkaline solution can be used. These replacement liquids can effectively test the anti-corrosion coating to ensure that its performance can be verified in various environments.

[0027] See also Figure 4 and Figure 6 The angle adjustment assembly includes a first rotating shaft 2; one end of the first rotating shaft 2 is fixedly connected to one side of the first disc 11, and the other end of the first rotating shaft 2 can extend to the outside of the detection box 1; a motor 21 is provided on the outside of the detection box 1, and the output end of the motor 21 is fixedly connected to the first rotating shaft 2.

[0028] The above scheme is adopted: when in use, when the angle of the first disc 11 needs to be adjusted, the output end of the motor 21 rotates to drive the first rotating shaft 2 to rotate synchronously. The rotation of the first rotating shaft 2 further causes the first disc 11 and the substrate to rotate synchronously, thereby realizing the adjustment of the angle of the first disc 11, ensuring that the substrate can maintain synchronization with the first disc 11 when adjusting the angle, so that the substrate can be completely covered by the liquid at any angle, effectively solving the problem of uneven contact area of ​​the anti-corrosion coating caused by the fluidity of the liquid when the substrate is fixed, ensuring that the liquid can completely cover the surface of the substrate, thereby improving the efficiency of anti-corrosion coating detection.

[0029] See also Figure 2 , Figure 4 and Figure 7 The dynamic detection component includes a first liquid circulation pipeline 3, one end of which is installed inside the detection box 1, and the other end of the first liquid circulation pipeline 3 is installed outside the detection box 1; one end of the first liquid circulation pipeline 3 is fixedly connected to a nozzle 31, and the nozzle 31 is located inside the detection box 1.

[0030] The above scheme is adopted: when in use, during the process of spraying liquid on the surface of the substrate, initially, the liquid will first flow through the first liquid circulation pipe 3, and then the liquid will enter the inside of the nozzle 31. When the liquid enters the nozzle 31, the liquid is evenly sprayed onto the surface of the substrate and comes into contact with the pre-applied anti-corrosion coating. Such contact can effectively detect the anti-corrosion effect or other specific properties of the anti-corrosion coating. However, not all sprayed liquids will directly contact the surface of the substrate. Some of the liquids will fail to contact the substrate for various reasons. These liquids will eventually flow into the bottom of the detection box 1, which is convenient for subsequent analysis and reuse, effectively avoiding waste of resources.

[0031] See also Figure 2 , Figure 7 and Figure 8 A liquid storage tank 4 is installed at the bottom of the detection box 1, one end of the first liquid circulation pipeline 3 is fixedly connected to one side of the liquid storage tank 4, and the first liquid circulation pipeline 3 can be interconnected with the liquid storage tank 4.

[0032] With the above solution, when in use, when liquid needs to flow into the first liquid circulation pipe 3 , the liquid in the liquid storage tank 4 can enter the first liquid circulation pipe 3 , and then the liquid passes through the first liquid circulation pipe 3 to reach the nozzle 31 .

[0033] See also Figure 4 A plurality of first fixing plates 5 are fixedly connected to the back of the first disc 11, each of which is provided with a first spring 51, one end of each of the first springs 51 is fixedly connected to the first fixing plate 5, the other end of each of the first springs 51 is fixedly connected to a support plate 52, each of which is fixedly connected to a first support frame 53, and a rolling roller 54 is rotatably connected to the first support frame 53.

[0034] The above solution is adopted: when in use, when the liquid level at the bottom of the detection box 1 is close to the bottom of the first disc 11, the first disc 11 rotates. This rotation drives the first spring 51 connected thereto, and through the action of the first fixed plate 5, the first spring 51 rotates synchronously with the first disc 11. Then, the rotation of the first spring 51 drives the rotation of the first support frame 53. The rolling roller 54 on the first support frame 53 rotates together with the first support frame 53.

[0035] During the rotation of the rolling roller 54, the rolling roller 54 will come into contact with the liquid at the bottom of the detection box 1. Through the rotation of the rolling roller 54, the rolling roller 54 can effectively push the contacted liquid to the outside. It should be noted that in order to achieve this process, a water outlet hole should be pre-set at the bottom of the detection box 1 to ensure that the liquid can flow out to the outside through this water outlet hole after being pushed by the rolling roller 54.

[0036] In addition, due to its own elastic characteristics, the first spring 51 can provide additional thrust to the rolling roller 54 while the rolling roller 54 pushes the liquid, thereby ensuring that the liquid can be dispersed to the outside.

[0037] It should be noted that: first, the diameter of the preset water outlet hole can be adjusted according to actual needs. Second, the preset water outlet hole needs to be opened at the bottom of the detection box 1 and must be longitudinally aligned with the rolling roller 54. Third, a one-way valve can also be installed in the preset water outlet hole to control the flow of liquid.

[0038] See also Figures 5 to 8 A third opening groove 6 is provided on the upper side of the liquid storage tank 4; a first airbag 61 is installed in the third opening groove 6, the upper half of the first airbag 61 extends into the detection box 1, and the lower half of the first airbag 61 extends into the liquid storage tank 4, and both sides of the first airbag 61 are fixedly connected to the edges of the third opening groove 6; a second airbag 62 is installed on the lower side of the first airbag 61, the second airbag 62 is located in the liquid storage tank 4, and both sides of the second airbag 62 are fixedly connected to the liquid storage tank 4.

[0039] The above scheme is adopted: when in use, when the rolling roller 54 rotates to the bottom of the detection box 1 with the first disc 11, it will contact the first airbag 61 at an angle of 180 degrees laid flat on the liquid storage tank 4. As the rolling roller 54 rotates, such as when the first rolling roller 54 rotates to 90 degrees, the first rolling roller 54 will contact the first airbag 61 and compress it, so that the first airbag 61 enters the liquid storage tank 4 through the third slot. At this time, the second rolling roller 54 located on the first disc 11 also begins to move toward the first airbag 61, forming a cyclic compression. The compression of the first airbag 61 gradually causes it to sink toward the second airbag 62, thereby compressing the second airbag 62. The deformation of the first airbag 61 and the second airbag 62 jointly changes the volume inside the liquid storage tank 4.

[0040] The above scheme has the following effects: First, when the pump body is used to extract the liquid in the liquid storage tank 4, if the above-mentioned scheme is not set, the pump body extracts the liquid. If the extraction speed is too fast or the amount of water in the liquid storage tank 4 is small, negative pressure will be formed in the liquid storage tank 4, and then the liquid storage tank 4 will be deformed or ruptured. After the above-mentioned scheme is set, the first airbag 61 and the second airbag 62 are inserted into the liquid storage tank 4. As the liquid decreases, the first airbag 61 and the second airbag 62 will expand and occupy part of the space, thereby preventing the formation of negative pressure.

[0041] Second, when the device is moving and the pump body is not needed to extract the liquid in the liquid storage tank 4, there is no liquid left at the bottom of the detection box 1, and the liquid in the liquid storage tank 4 is full. If the above scheme is not set, when the liquid storage tank 4 is full, the liquid inside it will naturally flow through the first liquid circulation pipe 3 and smoothly enter the nozzle 31 for spraying. However, once the amount of liquid in the liquid storage tank 4 is insufficient to maintain this continuous overflow state, the liquid supply inside the nozzle 31 will be short, resulting in a weakened or interrupted spraying effect. After the above scheme is set, when the liquid in the liquid storage tank 4 is insufficient to maintain the overflow state, as the liquid level drops, the first airbag 61 and the second airbag 62 will enter the liquid storage tank 4. The intervention of the first airbag 61 and the second airbag 62 creates a pressure difference by changing the volume in the liquid storage tank 4, thereby driving the liquid to flow into the first liquid circulation pipe 3. Not only does it promote the flow of liquid, but it also increases the pressure so that the liquid can flow out of the liquid storage tank 4 faster.

[0042] It should be noted that the rotation speed of the rolling roller 54 can directly affect the speed at which the first airbag 61 is deformed, and thus the rotation speed of the rolling roller 54 can be adjusted according to actual needs.

[0043] See also Figure 5 Two symmetrical second support frames 7 are fixedly connected to the upper side of the liquid storage tank 4. The second support frames 7 are respectively located on both sides of the first airbag 61. A second spring 71 is fixedly connected between the second support frame 7 and the first airbag 61.

[0044] The above scheme is adopted: during use, when the first airbag 61 is deformed and sinks, the first airbag 61 will pull the second spring 71 to sink synchronously. If the rolling roller 54 does not contact the first airbag 61, the second spring 71 will use its own elasticity to pull the deformed first airbag 61 to gradually rise and approach the second support frame 7, thereby effectively improving the efficiency of resetting the first airbag 61 and facilitating the rolling roller 54 to drive the first airbag 61 to sink again.

[0045] See also Figure 3 Two symmetrical first slideways 8 are provided in the second opening groove 12 , and electric sliders 81 are slidably connected in the first slideways 8 , and an arc-shaped baffle 82 is fixedly connected between the two electric sliders 81 .

[0046] With the above solution, when the substrate is placed in the installation groove 13, the electric slider 81 drives the arc-shaped baffle 82 to move in the first slideway 8, so that the installation groove 13 is in a closed state.

[0047] A dynamic detection method for anti-corrosion coatings comprises the following steps: Step S1, evenly applying the anti-corrosion coating on the substrate; Step S2, sending the substrate into the installation groove 13 through the first opening groove 14 and the second opening groove 12; Step S3, the dynamic detection component sprays a specific liquid, and the liquid contacts the surface of the substrate on the first disc 11, and then interacts with the anti-corrosion coating on the substrate, so as to detect the performance of the anti-corrosion coating; Step S4, the angle adjustment component drives the substrate to adjust the angle via the first disk 11.

[0048] Working principle of the present invention: In the actual operation of anti-corrosion coating testing, the first step is to ensure that the anti-corrosion coating is evenly coated on the substrate. When the performance evaluation of these anti-corrosion coatings is required, the substrate is first placed in the first opening slot 14, which is directly connected to the test box 1, so that the substrate can smoothly enter the internal space of the test box 1.

[0049] Next, the substrate is further pushed to the second opening groove 12 , which is communicated with the mounting groove 13 , to ensure that the substrate can smoothly enter the mounting groove 13 .

[0050] When the substrate completely enters the mounting groove 13, the dynamic detection component is activated and starts to spray a specific test liquid, which directly contacts the surface of the substrate on the first disc 11 and reacts chemically with the anti-corrosion coating thereon, thereby evaluating the performance of the anti-corrosion coating.

[0051] If it is necessary to perform multi-angle detection on the substrate to obtain a more comprehensive evaluation result, start the angle adjustment component to drive the first disc 11 to rotate. Since the substrate is fixed on the first disc 11, it will adjust its angle as the disc rotates. During this process, the dynamic detection component will continue to spray liquid to ensure that the surface of the substrate can be evenly covered by the liquid at any angle, thereby achieving a comprehensive and efficient detection of the performance of the anti-corrosion coating.
