Description

Technical Field

[0001] The invention relates to the technical field of tunnel water seepage detection, and in particular to a measuring instrument for intelligent detection of tunnel water seepage. Background Art

[0002] The water seepage in the internal end wall of the tunnel is mainly caused by the abundant groundwater in the upslope body, which leaks outward. The drainage ditch on the top of the tunnel is not draining smoothly, causing surface water to accumulate. The increased water pressure leads to leakage. The groundwater in the upslope body is mainly fissure water, and the seepage is serious in the rainy season and is seasonal. Therefore, it is necessary to regularly inspect and measure the top of the tunnel, and bring the detection instrument into contact with the wall inside the tunnel. At the same time, it is necessary to adjust the position at regular intervals to promptly detect whether there is a leakage problem in the top wall inside the tunnel.

[0003] Normally, the detection instrument is placed on a lifting platform or on the top of a vehicle to detect water leaks on the tunnel surface. However, the existing detection instruments have the following problems: when detecting arched tunnels, there is a gap between the detection instrument and the top of the tunnel, and the detection instrument cannot contact the inside of the tunnel well, resulting in inaccurate detection; the detection instrument can only be lifted and lowered at a fixed point, and cannot perform large-area detection on an area of the tunnel inner wall. Large-area screening usually requires manual point-by-point inspection, which has a long screening cycle, high labor costs, cumbersome operation, and is time-consuming and labor-intensive; the detection instrument cannot detect accurately when there is less water seepage. Summary of the invention

[0004] The purpose of the present invention is to provide a measuring instrument for intelligent detection of tunnel water leakage, which can perform large-area screening detection with high work efficiency and can detect accurately when there is less water leakage.

The detection component comprises a detection plate, a camera, a sponge detector and an ultrasonic radar, the detection plate is connected to the telescopic component, the camera, the sponge detector and the ultrasonic radar are all installed on the detection plate, and pulleys are installed on all four sides of the detection plate; Adjusting assembly, the adjusting assembly includes a driving member, a bidirectional screw, two sliders and two support rods. The driving member is installed on the detection plate. The bidirectional screw is installed at the output end of the driving member.

The driving member drives the bidirectional screw to rotate self, driving the two sliders to move away from or close to each other to adjust the distance between the sponge detector and the detection plate.

[0019] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0020] This embodiment provides a measuring instrument for intelligent detection of tunnel water leakage, which is capable of conducting large-area screening and detection with high work efficiency and accurate detection when there is little water leakage.

[0021] See also Figures 1 to 4 A measuring instrument for intelligent detection of tunnel water leakage includes a connecting member 1, a plurality of telescopic components 2 connected to the outer wall of the connecting member 1 at circumferential intervals, and a detection component 3 installed at the end of the telescopic component 2 away from the connecting member 1.

[0022] Among them, the length of the telescopic component 2 is shortened after being compressed. During the detection process, as the height increases, the detection component 3 contacts the inner wall of the tunnel and squeezes the telescopic component 2. The telescopic component 2 is shortened, allowing the detection component 3 to fully contact the inner wall of the tunnel, perfectly fitting the curved tunnels of different curvatures, thereby obtaining accurate detection data.

[0023] For example, see Figure 2 and Figure 3, the telescopic component 2 includes a fixed column 21, a sleeve column 22 and a compression spring 23. One end of the fixed column 21 is connected to the connecting member 1, and the other end of the fixed column 21 is provided with a chuck 211 which protrudes circumferentially from the fixed column 21. One end of the sleeve column 22 is open and sleeved on the fixed column 21, and the other end of the sleeve column 22 is connected to the detection component 3. The inner wall of the open end of the sleeve column 22 is provided with a limiting step 221 which is circumferentially limited to the chuck 211. One end of the compression spring 23 abuts against the chuck 211, and the other end abuts against the inner wall of the sleeve column 22. Through the above settings, in the idle state, the limiting step 221 is circumferentially limited to the chuck 211. As the height rises, the detection component 3 contacts the inner wall of the tunnel and compresses the sleeve column 22, and the sleeve column 22 compresses the compression spring 23, thereby shortening the overall length of the sleeve column 22 and the fixed column 21, so that multiple detection components 3 can fully contact the inner wall of the tunnel, thus improving the detection accuracy.

[0024] It should be noted that the compression spring 23 is always in a compressed state.

[0025] Please refer to Figure 1 and Figure 2 , the detection component 3 includes a detection board 31 and a camera 32 installed thereon. The detection board 31 is connected to the other end of the sleeve column 22, and pulleys 33 are installed around the detection board 31, which can drive the whole to slide. Through the above settings, when the pulleys 33 drive the whole to move quickly, the camera 32 can identify the possible water leakage areas and regions, and at the same time feedback the suspicious points, thereby realizing large-area screening detection and improving the efficiency and accuracy of tunnel water leakage detection.

[0026] Preferably, the camera 32 is installed at the edge of the detection board 31 to prevent affecting the detection. Further preferably, the camera 32 is located at one end in the traveling direction of the pulley 33 to ensure that the camera 32 can identify the front picture.

[0027] Optionally, the multiple detection boards 31 in this embodiment are arranged in a ring shape, that is, the cross-sections of the multiple detection boards 31 are located on the same regular polygon to fit the wall surface of the arched tunnel.

[0028] The detection component 3 further includes a sponge detector 34 and an ultrasonic radar 35. The sponge detector 34 is installed in the middle area of the detection board 31 to avoid the influence of the pulley 33, and the ultrasonic radar 35 is installed at the edge of the detection board 31 to prevent affecting the detection. By installing the sponge detector 34 on the detection board 31, fixed-point accurate detection and judgment are carried out on the tunnel wall surface. By setting the ultrasonic radar 35, it can effectively detect and prevent the places where water leakage has occurred and may occur in the tunnel, and ensure the accuracy of detection in the case of less seepage.

[0029] Preferably, several ultrasonic radars 35 are installed at intervals on the edge of the detection board 31 to avoid missing detection points and improve the comprehensiveness of detection.

[0030] Furthermore, to ensure the overall sliding during large-area screening without damaging the sponge detector 34, in this embodiment, the distance between the sponge detector 34 and the detection board 31 is adjustable. During the sliding process, the distance between the sponge detector 34 and the detection board 31 is shortened to avoid the sponge detector 34 rubbing against the tunnel tightly and causing damage.

[0031] Specifically, a measuring instrument for intelligent detection of tunnel leakage also includes an adjustment component. Please refer to Figure 4 , the adjustment component is used to adjust the distance between the sponge detector 34 and the detection board 31. The adjustment component connects the sponge detector 34 and the detection board 31. The adjustment component includes a driving member 41, and the driving member 41 is configured to drive the sponge detector 34 away from or close to the detection board 31.

[0032] Exemplarily, the adjustment component further includes a bidirectional screw 42, two sliders 43 and two support rods 44. Among them, the bidirectional screw 42 is installed at the output end of the driving member 41, and the two sliders 43 are respectively screwed to both ends of the bidirectional screw 42. One ends of the two support rods 44 are respectively rotatably connected to the two sliders 43, and the other ends of the two support rods 44 are rotatably connected to the sponge detector 34. Through the above settings, controlling the driving member 41 to drive the bidirectional screw 42 to rotate self, driving the two sliders 43 to move away from or close to each other, and then adjusting the distance between the sponge detector 34 and the detection board 31.

[0033] In some feasible embodiments, a fixing block is installed on the back of the sponge detector 34, and the other ends of the two support rods 44 are both rotatably connected to the fixing block.

[0034] Optionally, the adjustment component further includes a sliding guide frame 45 installed on the detection board 31. The bidirectional screw 42 is rotatably arranged inside the sliding guide frame 45, and the driving member 41 is installed on the sliding guide frame 45. Specifically, the driving member 41 is installed on the outer wall of the sliding guide frame 45. In this embodiment, one end of the bidirectional screw 42 passes through the sliding guide frame 45 and is connected to the output end of the driving member 41 to avoid the driving member 41 affecting the sliding of the slider 43 inside the sliding guide frame 45.

[0035] Furthermore, the opposite sides of the slider 43 are respectively slidably limited to the inner wall of the sliding guide frame 45. Sliding grooves are opened on the opposite sides of the inner wall of the sliding guide frame 45. The sliding grooves are arranged along the axial direction of the bidirectional screw 42. The opposite sides of the slider 43 are respectively slidably limited to the two sliding grooves to ensure the sliding stability of the slider 43 and limit the circumferential degree of freedom of the slider 43 at the same time.

[0036] A measuring instrument for intelligent detection of tunnel seepage water provided in this embodiment enables the sponge detector 34 to fully contact the inner wall of the tunnel by setting the telescopic assembly 2, perfectly fitting the arc-shaped tunnel with different radian to obtain accurate detection data; by installing a camera 32 on the detection board 31 and installing pulleys 33 around it, the pulleys 33 can drive the whole to move quickly. During this process, the camera 32 identifies the places and areas where water leakage may occur and simultaneously feeds back suspicious points, thus realizing large-area screening detection and improving the efficiency of tunnel water leakage detection; by installing a sponge detector 34 on the detection board 31, it conducts fixed-point accurate detection and judgment on the tunnel wall surface. By setting an ultrasonic radar 35 on the detection board 31, it can effectively detect and prevent the places where water leakage has occurred and may occur in the tunnel, ensuring the accuracy of detection in the case of less seepage water; by setting an adjustment assembly to adjust the distance between the sponge detector 34 and the detection board 31, it ensures that during the large-area screening process, while the whole slides, the sponge detector 34 is not damaged.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
