Description

Technical Field

[0001] This utility model belongs to the field of stress and strain monitoring technology, specifically a visual strain coating and a visual strain monitoring system. Background Technology

[0002] With the development of engineering construction, finite element simulation analysis is used to analyze the stress and strain of objects in engineering design. However, the hardware and software required for finite element simulation are relatively complex to operate and cannot reflect the strain process of a structure throughout its entire life cycle.

[0003] In existing technologies, visual strain detection sensors are mostly used to solve this technical problem. Specifically, strain sensors are attached to the surface of the structure, and strain values ​​on the surface are combined with computer data statistics and modeling to draw strain contour maps. Although this can reflect the strain process of the structure throughout its entire life cycle, it requires, on the one hand, to place strain sensors on top of the existing coatings of structures such as walls, increasing costs; on the other hand, it requires hardware processors and software data processing to draw the strain contour maps of the structure, resulting in high costs for the supporting equipment. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a visual strain coating and a visual strain monitoring system, which can not only be used as a coating on the surface of a structure, but also reflect the strain process of the structure throughout its entire life cycle through color changes.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This invention first proposes a visual strain coating, comprising:

[0007] Structural layer, installed on the surface of the main structural body;

[0008] A deformable layer is installed on the structural layer and can deform as the surface shape of the main structure changes.

[0009] A coloring layer is installed on the deformation layer and deforms synchronously with the deformation layer;

[0010] A waterproof layer, installed on the colored layer, is made of a flexible transparent material;

[0011] The color of the coloring layer varies depending on the size of the convex or concave deformation it produces, and thus displays different colors.

[0012] Furthermore, the structural layer is made of wire mesh that is fixedly attached to the surface of the main structure.

[0013] Furthermore, the deformable layer is made of sponge.

[0014] Furthermore, the coloring layer is made of color particle soft rubber, which includes a soft rubber body and color particles, and the color particles are arranged within the software body at a set discrete distance.

[0015] This invention also proposes a visual strain monitoring system, including a spectrophotometer for detecting the color of the surface of the main structure and a data processor for processing the color data collected by the spectrophotometer. The surface of the main structure is equipped with the visual strain coating described above.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention's visual strain coating enhances the connection between the coating and the main structural surface by incorporating a structural layer, preventing coating detachment. A deformation layer is placed between the structural and coloring layers, allowing the coloring layer to freely deform according to changes in the shape of the main structural surface. A waterproof layer made of a head-shaped transparent material provides waterproofing without interfering with the deformation of the coloring layer. Thus, this visual strain coating can be directly applied to the surface of the main structural element. When the surface of the main structural element deforms outward or inward due to changes in internal stress, the coloring layer in the corresponding area will also deform outward or inward and display different colors. By observing the color changes of the coloring layer, the strain process of the structure throughout its entire lifespan can be reflected. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] like Figure 1 As shown, the visualized strain coating includes a structural layer 2, a deformation layer 3, a coloring layer 4, and a waterproof layer 5. Specifically, the structural layer 2 is installed on the surface of the main structure 1; the deformation layer 3 is installed on the structural layer 2 and deforms with changes in the shape of the surface of the main structure 1. The coloring layer 4 is installed on the deformation layer 3 and deforms synchronously with the deformation layer 3. The waterproof layer 5 is installed on the coloring layer 4 and is made of a flexible transparent material. Specifically, in this embodiment, the color of the coloring layer 4 varies with the size of its convex or concave deformation and displays different colors.

[0027] In this embodiment, the structural layer 2 is a wire mesh that is fixedly hung on the surface of the main body 1. This not only enhances the connection strength with the surface of the main body 1, but also provides support for the deformation layer 3, the coloring layer 4, and the waterproof layer 5, effectively preventing the coating from falling off the surface of the main body 1.

[0028] In this embodiment, the deformation layer 3 is made of sponge. On the one hand, it acts as a pad for the coloring layer 4 to prevent the unevenness of the structural layer 2 from affecting the initial deformation of the coloring layer 4. On the other hand, the softness of the sponge can be used to transfer the deformation of the surface of the main body 1 to the coloring layer 4, so that the coloring layer 4 can deform freely.

[0029] like Figure 2 As shown, in this embodiment, the coloring layer 4 is made of color particle soft rubber, which includes a soft rubber body 41 and color particles 42. The color particles 42 are arranged within the soft rubber body 41 at a set discrete distance. Thus, when the coloring layer 4 deforms, the discrete distance of the color particles 42 changes, and the color of the coloring layer 4 changes accordingly. Specifically, as... Figure 3-4 As shown, when the coloring layer 4 undergoes outward convex deformation, the discrete spacing between the color particles 42 increases, and the color of the coloring layer 4 becomes lighter; as Figure 5-6 As shown, when the coloring layer 4 undergoes concave deformation, the discrete spacing between the color particles 42 decreases, and the color of the coloring layer 4 becomes darker. Conversely, the strain of the main structure 1 can be reflected by the change in the color depth of the coloring layer 4, thus realizing the visualization of the surface strain of the main structure 1.

[0030] This embodiment also proposes a visual strain monitoring system, including a spectrophotometer for detecting the color on the surface of the main structure 1 and a data processor for processing the color data collected by the spectrophotometer. The surface of the main structure is covered with the visual strain coating described above in this embodiment. Specifically, the dispersion of the color particles 4 is related to the thickness of the visual strain coating. The greater the coating thickness, the greater the influence of deformation on the color particles 4 on the surface of the color layer 4, and thus the more obvious the change in the dispersion distance of the color particles 4. Considering that the coating thickness used in general is usually very thin, it is difficult for the human eye to distinguish the color change of the color layer 4. Therefore, this embodiment uses a spectrophotometer to detect the color of the structural coating, and then transmits it remotely to the data processor. The data processor can obtain the RGB values ​​of the color collected by the spectrophotometer, and the RGB values ​​can directly reflect the strain on the surface of the main structure 1.

[0031] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
