Description

Technical Field

[0001] This invention relates to the field of visual FRP material testing technology, specifically to a device for detecting the erosion diffusion depth of visual FRP materials. Background Technology

[0002] FRP is a lightweight, high-strength composite material made of fiber and resin matrix. The material itself integrates functions such as color change, fluorescence, and light transmission. When subjected to stress and damage, it actively presents visual signals. Non-destructive testing equipment is used to image conventional FRP to restore its internal structure and defects. In environments such as water, chloride ions, acids and alkalis, salt spray, and high-temperature aging, the medium will diffuse and erode from the surface to the interior of FRP, leading to resin degradation, fiber-matrix interface failure, and a decrease in mechanical properties. Visualized erosion diffusion depth detection uses imaging analysis to intuitively display and accurately measure the erosion front, diffusion path, and erosion layer thickness.

[0003] The erosion diffusion depth of FRP materials can be detected by ultrasound, which can image and display the tiny defects inside the material and the erosion diffusion interface. When using the ultrasound detection device, there are different degrees of corrosive media residues in acid-alkali and dry-wet cycle environments. However, the existing device is not convenient to convert FRP materials to acid-alkali and dry-wet cycle environments.

[0004] Combining the above problems, we find that existing devices for detecting the erosion diffusion depth of FRP materials are difficult to avoid the aforementioned issues when in use. Even if they can be solved, they require external tools, thus failing to achieve the desired effect. Therefore, we propose a device for detecting the erosion diffusion depth of FRP materials.

[0020] 1. This invention, by incorporating a displacement conversion unit, enables the height adjustment of the test material, allowing for the precise delivery of FRP material samples into different cavities within the test chamber. Simultaneously, it allows for horizontal position adjustment of the material. Furthermore, based on height and position adjustments, it enables the conversion of the test material under different testing environments, effectively solving the problem of existing devices being inconvenient for position conversion under different corrosive environments.

[0021] 2. This invention, by incorporating a solution modulation unit, can precisely prepare etching solutions of different concentrations. Specifically, the detection chamber is divided into an acid-base chamber, a wetting chamber, and a drying chamber by a partition plate. These chambers can store acidic solutions, alkaline solutions, and clean water for wetting treatment, respectively, thereby accurately simulating various concentration etching environments that FRP materials may encounter in practical applications.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-4 The present invention provides a technical solution: a detection device for visualizing the erosion diffusion depth of FRP material, including a main body 1, the main body 1 including a detection box 11, a linear slide rail 12 fixedly installed on the upper surface of the detection box 11, and a detection conversion mechanism 2 provided above the detection box 11;

[0035] The detection conversion mechanism 2 includes a displacement conversion unit 21, which is located above the detection box 11. The displacement conversion unit 21 is used to move the detection material so that the detection material is in different detection environments.

[0036] As a further definition of the detection and conversion mechanism 2 of the present invention, the displacement conversion unit 21 includes a fixed frame 2101. One side of the fixed frame 2101 is fixedly connected to one side of the linear slide rail 12. Two support arms 2105 are fixedly installed on the side of the fixed frame 2101 away from the linear slide rail 12. A first lead screw 2111 is rotatably connected to the inner wall of one support arm 2105, and a movable arm 2112 is slidably connected inside the other support arm 2105. Lifting housings 2104 are fixedly installed on both sides of the movable arm 2112. A second lead screw 2106 is rotatably connected to the inner wall of each lifting housing 2104. Both the outer surfaces of the first lead screw 2111 and the second lead screw 2106 are threaded with matching nuts 2118. Lifting sliders 2107 are fixedly mounted on the outer surfaces of both matching nuts 2118. The outer surface of each lifting slider 2107 contacts the inner wall of the lifting housing 2104. A first synchronous pulley 2119 is fixedly mounted on the outer surface of each second lead screw 2106. The outer surfaces of the two first synchronous pulleys 2119 are connected to a first synchronous belt 2117 for transmission. A dual-axis motor 2102 is fixedly mounted on the top of one of the second lead screws 2106. The bottom surface of the dual-axis motor 2102 is connected to one of the lifting housings. A key shaft 2103 is fixedly connected to the upper surface of the lower housing 2104. A second synchronous pulley 2116 is fixedly mounted on one output end of the dual-axis motor 2102. The outer surface of the key shaft 2103 and the outer surface of the first lead screw 2111 are both provided with second synchronous pulleys 2116. The interior of one of the second synchronous pulleys 2116 is slidably connected to the outer surface of the key shaft 2103. A second synchronous belt 2114 is drivenly connected to the outer surface of each second synchronous pulley 2116. The inner rings of the two second synchronous belts 2114 are jointly drivenly connected to a double-grooved pulley 2120. A support shaft 2113 is fixedly mounted on the inner wall of the double-grooved pulley 2120. The outer surface of the support shaft 2113 is fixedly connected to the key shaft 2102. The inner wall of the fixed frame 2101 is rotatably connected, and a rotating tube 2115 is fixedly installed on one side of one of the second synchronous wheels 2116. The outer surface of the rotating tube 2115 is rotatably connected to the inner wall of the fixed frame 2101. By setting a displacement conversion unit 21, the height of the test material can be adjusted so that the FRP material sample can be accurately sent into different cavities in the test chamber 11. At the same time, the position of the material in the horizontal direction can be adjusted. Furthermore, based on the height adjustment and position adjustment, the test material can be converted in different test environments, which effectively solves the problem that the existing device is inconvenient to convert the position in different corrosive environments.

[0037] Please see Figure 3Each support arm 2105 has a mounting plate 2108 fixedly installed on one side, and an ultrasonic detector 2109 is fixedly installed on the inner wall of each mounting plate 2108. Through the mounting plate 2108 and the ultrasonic detector 2109, ultrasonic signals can be emitted simultaneously from both sides of the FRP material sample after the etching process is completed. By utilizing the differences in the propagation speed and reflection characteristics of ultrasonic waves in different media, the erosion diffusion area inside the material can be scanned and imaged, thereby intuitively presenting the erosion depth and range, and providing accurate detection data for subsequent depth analysis.

[0038] Please see Figure 3 Two guide rods 2110 are fixedly installed on the inner wall of one of the support arms 2105. The outer surface of each guide rod 2110 is slidably connected to the inside of the moving arm 2112. Through the guide rods 2110, the moving arm 2112 can provide guidance when it slides along the support arm 2105, effectively preventing the moving arm 2112 from deviating or shaking during horizontal movement, ensuring the straightness of its movement trajectory, and thus ensuring that the FRP material sample held under the moving arm 2112 can be accurately aligned with each cavity in the detection box 11.

[0039] Please see Figure 4 The inner wall of the movable arm 2112 is rotatably connected with several identical rollers 2121. The outer surface of each roller 2121 is in contact with the inner wall of one of the support arms 2105. Through the rollers 2121, the sliding friction between the movable arm 2112 and the support arm 2105 can be converted into rolling friction, making the horizontal movement of the movable arm 2112 more stable and smooth.

[0040] The specific implementation of this embodiment is as follows: During the FRP material testing process, it is necessary to convert the FRP material to different environments and move the FRP material in both linear and vertical positions. One output of the dual-axis motor 2102 can be activated to drive the key shaft 2103 to rotate. The key shaft 2103 transmits power to the second synchronous pulley 2116 on the first lead screw 2111 via the second synchronous belt 2114 and the double-groove pulley 2120, thereby driving the first lead screw 2111 to rotate. The rotation of the first lead screw 2111 causes the matching nut 2118 to drive the moving arm 2112 to slide horizontally along the guide rod 2110 within the support arm 2105. Simultaneously, the rollers 2121 on the inner wall of the moving arm 2112 slide horizontally within the support arm 2105. The wall roll reduces friction and ensures smooth movement. When the height of the FRP material sample needs to be adjusted, the other output end of the dual-axis motor 2102 is started, which drives the second lead screw 2106 connected to it to rotate. The second lead screw 2106 drives another second lead screw 2106 to rotate synchronously through the first synchronous pulley 2119 and the first synchronous belt 2117. The rotation of the second lead screw 2106 causes the matching nut 2118 to drive the lifting slider 2107 to move up and down along the inner wall of the lifting housing 2104, thereby realizing the height adjustment of the material clamping mechanism 3 and the FRP material sample. Through the coordinated adjustment of the horizontal and vertical dimensions, the FRP material sample can be accurately sent into each cavity in the testing chamber 11 for erosion treatment under different environments.

[0041] Example 2: Please refer to Figure 1 and Figures 5-8 The present invention provides a technical solution: a detection device for visualizing the erosion diffusion depth of FRP materials. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The detection conversion mechanism 2 also includes a solution modulation unit 22, which is located inside the detection box 11. The solution modulation unit 22 is used to accurately mix and store erosion solutions of different concentrations and temperatures required for erosion detection, so as to simulate various erosion environments that FRP materials may encounter in actual applications.

[0042] As a further definition of the detection and conversion mechanism 2 of the present invention, the solution modulation unit 22 includes a partition plate 2201. The outer surface of the partition plate 2201 is fixedly connected to the inner wall of the detection chamber 11. The detection chamber 11 forms an acid-base chamber 2206, a wetting chamber 2205, and a drying chamber 2204 through the partition plate 2201. Two drying fans 2203 are fixedly installed on the inner wall of the drying chamber 2204. An extraction pump 2202 is fixedly installed on the upper surface of the partition plate 2201. An extraction pipe 2208 is fixedly connected to the input end of the extraction pump 2202. The bottom of the extraction pipe 2208 passes through the partition plate 2201. The internal structure has two fixed connections to first control valves 2210. The output end of the extraction pump 2202 is fixedly connected to a distribution pipe 2209. Both ends of the distribution pipe 2209 pass through the partition plate 2201 to the interior of the acid-base chamber 2206 and the drying chamber 2204. The internal structure of the distribution pipe 2209 is fixedly connected to a second control valve 2207. A rotary motor 2214 is fixedly mounted on the upper surface of one of the support arms 2105. A limit frame 2212 is fixedly mounted on the output end of the rotary motor 2214. A servo motor 2213 is fixedly mounted on the upper surface of the limit frame 2212. A [missing information - likely a device or component] is fixedly mounted on the output end of the servo motor 2213. A lifting screw 2221 has a lifting plate 2215 threadedly connected to its outer surface. The outer surface of the lifting plate 2215 contacts the inner wall of the limiting frame 2212. A baffle 2211 is fixedly installed on the bottom surface of the lifting plate 2215. Several identical rotating shafts 2219 are rotatably connected to the inner wall of the baffle 2211. A synchronous gear 2220 is fixedly installed on the outer surface of each rotating shaft 2219. A drive motor 2218 is fixedly installed at the top of one of the rotating shafts 2219. A stirring blade 2216 is fixedly installed on the outer surface of each rotating shaft 2219. A solution modulation unit 22 is also provided. It can accurately prepare etching solutions of different concentrations. Specifically, the internal structure of the detection chamber 11 is divided into an acid-base chamber 2206, a wetting chamber 2205, and a drying chamber 2204 by a partition plate 2201. These chambers can store acidic solutions, alkaline solutions, and clean water for wetting treatment, respectively, thereby accurately simulating various concentration etching environments that FRP materials may encounter in actual applications. In addition, the drying fan 2203 in the drying chamber 2204 can quickly dry the material after wetting or etching treatment, realizing the simulation of a wet-dry cycle environment and providing more comprehensive environmental conditions for the detection of the etching diffusion depth of FRP materials.

[0043] Please see Figure 7A bracket 2217 is fixedly installed on the upper surface of the baffle 2211. The outer surface of each rotating shaft 2219 is rotatably connected to the inner wall of the bracket 2217. The bottom surface of the drive motor 2218 is fixedly connected to the upper surface of the bracket 2217. Through the bracket 2217, the top of the rotating shaft 2219 can be stably supported, ensuring that when the drive motor 2218 drives the rotating shaft 2219 and the stirring blade 2216 to rotate at high speed, the rotating shaft 2219 will not shake or deviate due to centrifugal force, and ensuring that the stirring blade 2216 can stir the solution evenly and stably.

[0044] The specific implementation of this embodiment is as follows: The detection box 11 is divided into multiple cavities by a partition plate 2201. The outer space of the cavity is used to store acid and alkali solutions and soaking liquids. According to the needs, the extraction pump 2202 is started to extract the liquid stored in the space formed by the partition plate 2201 and the detection box 11 through the extraction pipe 2208. The extraction of acidic solution, alkaline solution or water is selected by controlling the opening and closing of the first control valve 2210. The extracted solution is pressurized by the extraction pump 2202 and delivered to the distribution pipe 2209. Then, by adjusting the second control valve 2207, the solution is accurately distributed to the designated treatment area in the detection box 11 to prepare the required concentration of the etching solution. When it is necessary to stir and mix the solution, the rotary motor 2214 is started to drive the limit frame 221. 2. Rotate to above the solution, then start the servo motor 2213 to drive the lifting screw 2221 to rotate, so that the lifting plate 2215 moves downward along the inner wall of the limit frame 2212, thereby extending the baffle 2211 and the stirring blade 2216 into the solution. Then start the drive motor 2218 to drive one of the rotating shafts 2219 to rotate. This rotating shaft 2219 drives the other rotating shafts 2219 to rotate synchronously through the synchronous gear 2220, thereby making the stirring blade 2216 to fully stir the solution and ensure that the solution concentration is uniform. After the solution is prepared, the FRP material sample is sent into the corresponding cavity for etching treatment through the displacement conversion unit 21. If it is necessary to simulate the dry and wet cycle, the sample is moved to the drying chamber 2204 after the etching treatment, and the drying fan 2203 is started to dry it.

[0045] Example 3: Please refer to Figure 1 and Figure 9 The present invention provides a technical solution: a detection device for visualizing the erosion diffusion depth of FRP material. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A material clamping mechanism 3 is provided below the detection conversion mechanism 2. The material clamping mechanism 3 is located above the detection box 11. The material clamping mechanism 3 is used to firmly clamp the FRP material sample to ensure the stability of the sample detection position during the detection process.

[0046] As a further definition of the material clamping mechanism 3 of the present invention, the material clamping mechanism 3 includes two limiting plates 301. One side of each limiting plate 301 is fixedly connected to one side of the lifting slider 2107. Four slot plates 305 are fixedly installed on the side of the two limiting plates 301 that are close to each other. Double-threaded screws 303 are rotatably connected to the inner wall of each slot plate 305. The outer surface of each double-threaded screw 303 is rotatably connected to the inner wall of the limiting plate 301. Three support plates 302 are fixedly installed on the side of the two limiting plates 301 that are close to each other. Two clamping plates 304 are threadedly connected to the outer surface of two double-threaded screws 303, and two fixing plates 306 are threadedly connected to the outer surface of the other two double-threaded screws 303. By providing the material clamping mechanism 3, it is possible to... It can clamp and fix FRP material samples in a multi-dimensional and stable manner. Specifically, the three support plates 302 form a stable support for the bottom of the sample to prevent the sample from sagging or shifting due to gravity during the detection process. At the same time, the clamping structure of the clamping plate 304 and the fixing plate 306 can adapt to FRP material samples of different sizes and shapes, ensuring that the sample maintains the accuracy and stability of the detection position throughout a series of detection processes such as position change, solution erosion, and drying. It avoids affecting the accuracy of the ultrasonic detection device in imaging the erosion diffusion depth due to sample shaking or displacement. During the entire process of environmental change, it ensures the continuity and stability of acid-base and dry-wet cycle environment conversion, ensuring that the sample can be accurately delivered into the target detection cavity and achieve smooth switching between different erosion environments.

[0047] The specific implementation of this embodiment is as follows: During the movement or soaking of FRP material, to prevent the FRP material from moving, the FRP material can be fixed according to its shape when placed. Cylindrical FRP materials are fixed by clamping plates 304, while square FRP materials are fixed by fixing plates 306. Specifically, the FRP material sample is placed on three support plates 302 for stable support. If the sample is cylindrical, the double-threaded screw 303 inside the corresponding groove plate 305 is rotated. Since the threads on the outer surface of the double-threaded screw 303 rotate in opposite directions, its rotation will drive the two clamping plates 304 along the inner wall of the groove plate 305. The plates are brought closer together until the inner side of the clamping plate 304 is in close contact with the outer surface of the cylindrical sample, thus achieving lateral clamping and fixing of the cylindrical sample. If the sample is square or other planar, the double-threaded screws 303 in the other two slot plates 305 are rotated to drive the two fixing plates 306 to move towards each other along the inner wall of the slot plate 305, so that the inner side of the fixing plate 306 is in close contact with the two sides or other planar parts of the square sample, thereby completing the stable clamping of FRP material samples of different shapes and ensuring that the sample will not loosen or shift during subsequent position changes, etching treatments and ultrasonic testing.
