[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: In the solution of the present application: 1. In order to solve the problem that in the prior art, during the process of image acquisition in a tunnel, the detection structure cannot be folded and stored during transportation, which greatly reduces its usability. More seriously, when transporting inside the tunnel, this non-foldable detection structure is easily damaged, thus affecting its detection effect and service life.

Specific implementation manner

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As described in the background art, during the process of image acquisition in a tunnel, the detection structure cannot be folded and stored during transportation, which greatly reduces its usability. More seriously, when transporting inside the tunnel, this non-foldable detection structure is very likely to be damaged, thus affecting its detection effect and service life.

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0024] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0026] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, A tunnel image information acquisition device, including a frame 1. In the middle of the upper surface of the frame 1, an adjustment component 2 is provided. On one side of the upper surface of the frame 1, a protection component 3 is provided. The adjustment component 2 includes two auxiliary frames 201 that are symmetrically and evenly distributed and fixedly installed on the upper surface of the frame 1. On the opposite surfaces of the two auxiliary frames 201, auxiliary gears 202 are movably installed. Above the auxiliary gears 202, a sleeve 203 is fixedly connected. Inside the inner wall of the sleeve 203, an extension rod 204 is movably connected. On the outer wall of the sleeve 203, a side groove 207 is provided. On the outer wall of the extension rod 204, a square shaft 211 is provided. One end of the square shaft 211 penetrates through the side groove 207 and an auxiliary rod 210 is movably installed. At the end of the auxiliary rod 210 away from the square shaft 211, a slide rod 209 is provided. Below the auxiliary gear 202, a support rod 212 is provided. Above one side of the support rod 212, a toothed plate 214 is fixedly connected. On the other side surface of the support rod 212, a limit groove 213 is provided. At one end of the inner wall of the limit groove 213 away from the toothed plate 214, an elastic bump 215 is fixedly connected. The limit groove 213 is movably connected with the slide rod 209. The support rod 212 is driven by a fixed frame 217 to move towards the auxiliary frame 201, driving the slide rod 209 in the limit groove 213 to move. And under the block of the elastic bump 215, the auxiliary rod 210 is pulled to tilt around the square shaft 211, pulling the extension rod 204 in the sleeve 203 to move downward, adjusting the height of the arc plate 206. When the square shaft 211 moves to the bottom end of the side groove 207, the support rod 212 continues to move towards the auxiliary frame 201. Due to the limit of the square shaft 211, the slide rod 209 at the other end of the auxiliary rod 210 crosses the elastic bump 215. While crossing the elastic bump 215, the auxiliary gear 202 contacts the toothed plate 214. The support rod 212 continues to move, driving the toothed plate 214 to move accordingly, causing the auxiliary gear 202 to rotate, driving the arc plate 206 loaded with the detection probe 11 to flip around the axis of the auxiliary gear 202, and thus disengaging from the information acquisition of the tunnel.

[0027] The slide rod 209 is driven to move through the limit groove 213 in the support rod 212. And under the limit of the elastic bump 215, the detection probe 11 is driven to expand and contract. The toothed plate 214 above the support rod 212 cooperates with the auxiliary gear 202, causing it to drive the detection probe 11 to rotate around the axis of the auxiliary gear 202. Thus, it drives the detection structure to expand and contract and rotate, thereby improving the convenience of its information acquisition of the tunnel, and facilitating the storage and folding of the detection structure, increasing the protection of the detection structure during transportation.

[0028] Further, as Figure 6As shown, a fixing frame 217 is fixedly connected between two support rods 212. An electric telescopic rod 218 is fixedly connected to the middle of the fixing frame 217. The electric telescopic rod 218 drives the two support rods 212 to move with the fixing frame 217, thereby providing power for the displacement of the support rods 212.

[0029] Further, as Figure 5 shown in Figure 6 As shown, a slider 216 is fixedly connected to one end of the support rod 212 away from the fixing frame 217. The other end of the slider 216 is movably connected to a side chute 219. A side plate 208 is fixedly connected to the side of the side chute 219. The side plate 208 is fixedly installed on the upper surface of the frame 1. The displacement direction of the support rod 212 is restricted by the movement of the slider 216 in the side chute 219 provided in the side plate 208.

[0030] Further, as Figure 3 shown in Figure 4 As shown, a right-angle frame plate 205 is fixedly connected above the extension rod 204. An arc plate 206 is fixedly connected above the two right-angle frame plates 205. A number of detection probes 11 are fixedly connected to the outer wall of the arc plate 206 in a circumferentially uniform distribution. The other ends of the number of detection probes 11 are fixedly connected to a protection box 10. Both sides of the protection box 10 are fixedly installed on the sides of the right-angle frame plates 205. A protection component 4 is provided below the right-angle frame plates 205. Image acquisition operations of the tunnel are performed through the number of detection probes 11 connected to the protection box 10.

[0031] Embodiment 2 further optimizes the tunnel image information acquisition device provided in Embodiment 1. Specifically, as Figure 2 shown in Figure 3 shown in Figure 5 and Figure 7 As shown, the protection component 3 includes a support arc plate 305 fixedly installed at one end of the two side plates 208. An arc-shaped collection trough plate 304 is movably connected above the support arc plate 305. An arc-shaped cover plate 301 is provided above the arc-shaped collection trough plate 304. A number of brush plate grooves 303 are uniformly distributed on the inner wall of the arc-shaped cover plate 301. After the arc plate 206 contracts, it rotates around the axis of the auxiliary gear 202 and enters the arc-shaped cover plate 301 for storage and protection. When the arc plate 206 passes over the inner wall of the arc-shaped cover plate 301, the detection probes 11 in the arc plate 206 slide in the brush plate grooves 303 of the arc-shaped cover plate 301, and the detection probes 11 after use are cleaned. The dust that falls during cleaning falls into the arc-shaped collection trough plate 304 through the brush plate grooves 303 for collection.

[0032] The detection probe 11 after being rotationally stored is protected by the arc-shaped cover plate 301. During the storage and rotation process, the detection probe 11 slides through the brush plate groove 303 of the arc-shaped cover plate 301 to clean the detection probe 11, so that it can switch between the protection structure and the cleaning structure, improving the protection of the detection structure.

[0033] Further, as Figure 3 shown in Figure 5 the figure, a positioning frame 302 is fixedly connected to the lower part of the inner wall of the arc-shaped cover plate 301. Two limit clamping plates 306 are movably installed on both sides of the positioning frame 302. One side of the two limit clamping plates 306 is fixedly installed on the side surface of the arc-shaped collecting groove plate 304. The arc-shaped cover plate 301 is positioned through the positioning frame 302, and it cooperates with the limit clamping plates 306 to facilitate the disassembly and assembly of the arc-shaped collecting groove plate 304.

[0034] Example 3 further optimizes the tunnel image information acquisition device provided in Example 1, Figure 4 and Figure 7 Specifically, the protection component 4 includes a fixing plate 401 fixedly installed under the right-angle frame plate 205. One side of the fixing plate 401 away from the extension rod 204 is fixedly connected with an elastic telescopic rod 402. The other end of the elastic telescopic rod 402 is fixedly connected with a sliding frame plate 404. One side of the sliding frame plate 404 away from the elastic telescopic rod 402 is fixedly connected with a cross plate 405. A wheel body 406 is arranged on the outer wall of the cross plate 405. After the arc-shaped plate 206 is turned upward and extended, the wheel bodies 406 at both ends of the arc-shaped plate 206 come into contact with the inner wall of the tunnel to limit the height of the arc-shaped plate 206 in the tunnel. As the driving device moves in the tunnel, when vibrations occur during the movement, the arc-shaped plate 206 will tilt, and the wheel bodies 406 will shift towards the arc-shaped plate 206, squeezing the elastic telescopic rod 402 to contract and buffering the generated vibrations.

[0035] The wheel bodies 406 at both ends of the arc-shaped plate 206 come into contact with the inner wall of the tunnel to limit the height of the arc-shaped plate 206 in the tunnel. During the movement in the tunnel, the elastic telescopic rod 402 between the arc-shaped plate 206 and the wheel bodies 406 undergoes elastic buffering during vibrations, reducing the impact of vibrations on the acquisition process, so that it can switch between the height limiting structure and the buffering structure, ensuring the safety of image information acquisition of the tunnel.

[0036] Further, as Figure 4 shown in the figure, a limit sliding groove 403 is movably installed above the sliding frame plate 404, and the limit sliding groove 403 is fixedly installed directly below the right-angle frame plate 205. The movement direction of the sliding frame plate 404 is restricted through the limit sliding groove 403, reducing the impact of its vibrations on information acquisition.

[0037] Further, as Figure 1 shown, extension plates 5 are fixedly connected to both ends of the frame 1. Positioning pins 9 are provided on the surfaces of the extension plates 5. The positioning pins 9 located above the extension plates 5 are connected to the driving device to provide power for the movement of the overall structure.

[0038] Further, as Figure 1 shown, four limiting frames 7 are fixedly connected to the lower part of the frame 1 in a rectangular and evenly distributed manner. A rotating shaft 6 is movably connected between two limiting frames 7. Pulley 8 is fixedly connected to both ends of the rotating shaft 6 through the limiting frames 7. The pulley 8 connected by the rotating shaft 6 cooperates with the track in the tunnel to facilitate its movement in the tunnel.

[0039] The usage process of the tunnel image information acquisition device provided by the present invention is as follows: Working principle: The staff places the traction driving device at one end of the frame 1. The positioning pin 9 on the extension plate 5 is connected to the driving device, and both the traction driving device and the overall structure are placed on the track, and its pulley 8 is aligned with the track; Stretching: Start the electric telescopic rod 218 to pull the fixed frame 217 towards the arc-shaped cover plate 301 for movement, driving the two support rods 212 on both sides to move accordingly. The toothed plate 214 above the support rod 212 meshes with the auxiliary gear 202. As the support rod 212 moves, it pushes the toothed plate 214 to move accordingly, causing the auxiliary gear 202 to rotate. When it rotates to a state where the sleeve 203 is perpendicular to the support rod 212 and disengages from the arc-shaped cover plate 301, the support rod 212 continues to move towards the arc-shaped cover plate 301. The elastic bump 215 in the limit groove 213 contacts the sliding rod 209. Then, under the displacement of the support rod 212, the auxiliary rod 210 pushes the extension rod 204 to move upward. And under the limitation of the square shaft 211 in the side groove 207, the auxiliary rod 210 is vertically driven upward. When the square shaft 211 moves to the top of the side groove 207, the auxiliary rod 210 connected to the sliding rod 209 is limited, causing the sliding rod 209 to cross the elastic bump 215 in the limit groove 213, thereby locking the position of the sliding rod 209. At this time, the arc-shaped plate 206 is perpendicular to the frame 1, as Figure 7 shown; Shock absorption and protection: After the arc-shaped plate 206 is driven upward, the wheel body 406 at one end of the right-angle frame plate 205 contacts the inner wall of the tunnel to limit the height of the arc-shaped plate 206 in the tunnel. With the drive of the traction driving device, the wheel body 406 moves along the inner wall of the tunnel with the overall structure. When vibrations occur during the movement, the arc-shaped plate 206 will tilt, and the wheel body 406 will shift towards the arc-shaped plate 206, squeezing the elastic telescopic rod 402 to contract, buffering the generated vibrations, and thus collecting the image information of the tunnel; Storage: Activate the electric telescopic rod 218 to push the fixed frame 217 away from the arc cover plate 301, drive the two support rods 212 on both sides to move accordingly, move towards the auxiliary frame 201, drive the sliding rod 209 in the limit groove 213 to move, and under the block of the elastic bump 215, pull the auxiliary rod 210 to tilt around the square shaft 211, pull the extension rod 204 in the sleeve 203 to move downward, adjust the height of the arc plate 206. When the square shaft 211 moves to the bottom end of the side groove 207, the support rod 212 continues to move towards the auxiliary frame 201. Due to the limitation of the square shaft 211, the sliding rod 209 at the other end of the auxiliary rod 210 crosses the elastic bump 215. While crossing the elastic bump 215, the auxiliary gear 202 contacts the toothed plate 214. The support rod 212 continues to move, driving the toothed plate 214 to move accordingly, causing the auxiliary gear 202 to rotate, driving the arc plate 206 loaded with the detection probe 11 to flip around the axis of the auxiliary gear 202, and thus disengaging from the information collection of the tunnel; Storage protection: After the arc plate 206 contracts, it rotates around the axis of the auxiliary gear 202 and enters the arc cover plate 301 for storage protection. When the arc plate 206 passes over the inner wall of the arc cover plate 301, the detection probe 11 in the arc plate 206 slides in the brush plate groove 303 of the arc cover plate 301, and the detection probe 11 after use is cleaned. The dust falling during cleaning then falls along the brush plate groove 303 into the arc collection trough plate 304 for collection.
