Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel segment seepage detection technology, specifically a tunnel segment seepage detection device for shield tunnel construction. Background Technology
[0002] Shield tunnel construction technology is widely used in modern urban underground transportation, water conservancy, and other engineering projects. As the main support structure of a shield tunnel, the waterproofing performance of the tunnel segments directly affects the tunnel's safety and stability. However, during actual construction and operation, water seepage may occur in the tunnel segments. Since the temperature at the seepage points is often low, infrared detectors can be used to identify the seepage areas.
[0003] In the prior art, such as the tunnel segment seepage detection device described in patent number CN219142138U, a base and a rotating assembly are included. A support frame is provided at the upper end of the base, and the rotating assembly is located inside the support frame. The rotating assembly includes a motor, a connecting rod, a circular support plate, a short rotating block, a long rotating block, and a cylinder. The connecting rod is located at the upper end of the motor, and the circular support plate is located at the upper end of the connecting rod. Compared with existing tunnel segment seepage detection devices, this device, through the operation of the motor and cylinder, can not only adjust the nozzle to spray in all directions but also adjust the vertical distance of the nozzle, allowing the nozzle to spray the red liquid agent evenly onto the tunnel segments. This results in a larger spray range and better spraying effect. The movement of the slider causes the thin rod to extend from the thick rod, allowing the red liquid agent to be sprayed onto the higher-positioned segments in the tunnel, increasing the detection distance and thus improving the practicality of the device.
[0004] While the aforementioned patent can detect water seepage in tunnel segments, it still has some problems. Adjusting the angle by extending and retracting a cylinder often limits the range of angle adjustment, so some segments may not be able to be detected. In addition, the light inside the tunnel is often dim, making it difficult to observe seepage points. Therefore, this utility model provides a water seepage detection device for tunnel segments in shield tunnel construction. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a shield tunnel segment seepage detection device, which solves the problem that adjusting the angle by extending and retracting a cylinder often results in a limited adjustment range, making it possible to miss some segments.

[0007] The detection assembly includes a cross-shaped plate, with four grooves evenly distributed on the outer wall of the cross-shaped plate.

[0010] Preferably, an installation plate is fixedly installed on the outer wall of the cross-shaped plate, a second motor is fixedly installed on the outer wall of the installation plate, the output shaft of the second motor passes through the outer wall of the installation plate and is fixedly connected to a second bevel gear, the four extended slide plates are respectively movably inserted into the inner wall of the four slide grooves, and a control panel is fixedly installed on the outer wall of the mounting frame, the control panel being electrically connected to the four thermal imaging detectors respectively.

[0014] Beneficial effects
[0015] This invention provides a device for detecting water seepage in tunnel lining segments during shield tunnel construction. Compared with existing technologies, it has the following advantages:
[0016] 1. This shield tunnel segment seepage detection device, when segment inspection is required, first activates the second motor. The second motor drives the second bevel gear to rotate, and the four first bevel gears meshing with the second bevel gear rotate accordingly, causing the threaded rod to rotate within the slide groove. Since the threaded rod is threadedly connected to the extension slide plate, the extension slide plate extends outward along the slide groove, and the thermal imaging detector mounted on the extension slide plate also moves accordingly, bringing the thermal imaging detector closer to the segment, shortening the inspection distance, and making it easier for the thermal imaging detector to detect seepage areas. This improves the detection effect of the thermal imaging detector. Then, the first motor is activated, and the output shaft of the first motor drives the first gear to rotate. Since the first gear meshes with the second gear, it drives the rotating shaft and the cross-shaped plate to rotate, allowing the detection components to scan and inspect the segment from all directions, further improving the detection effect of the segment.
[0017] 2. This shield tunnel segment seepage detection device, after the thermal imaging detector detects a seepage area, adjusts the horizontal angle of the lighting lamp by rotating the circular plate and the vertical angle of the lighting lamp by adjusting the worm gear, so that the light beam of the lighting lamp rotates to the seepage area, thereby allowing for clearer observation of the detection results and improving the accuracy of the detection.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides two technical solutions:
[0028] Figures 1-7 The first embodiment is shown: a shield tunnel segment seepage detection device, including a movable plate 1, two sets of movable wheels 2 are fixedly installed at the bottom end of the movable plate 1, and a detection component 4 and a lighting component 5 are respectively provided at the top end of the movable plate 1.
[0029] The detection component 4 includes a cross-shaped plate 46. Four grooves 47 are evenly distributed on the outer wall of the cross-shaped plate 46. Threaded screws 415 are rotatably mounted on the inner walls of each of the four grooves 47. A circular groove 410 is formed on the outer wall of the cross-shaped plate 46. One end of each of the four threaded screws 415 extends through the inner wall of the circular groove 410 and is fixedly mounted with a first bevel gear 411. Second bevel gears 412 mesh with the outer walls of the four first bevel gears 411. When the second bevel gears 412 rotate, they can drive the four first bevel gears. Rotation of 411 causes four threaded screws 415 to rotate, which in turn drives the extension slide plate 48 to extend and retract, thereby adjusting the distance between the thermal imaging detector 49 and the pipe segment. The extension slide plate 48 is threadedly connected to the outer wall of the threaded screw 415, and the thermal imaging detector 49 is fixedly installed on the outer wall of the extension slide plate 48. The thermal imaging detector 49 is existing technology and can detect the temperature of the area. Since the temperature of the seepage area of the pipe segment is low, the seepage area of the pipe segment can be identified.
[0030] The lighting assembly 5 includes a support frame 51, a rotating circular plate 52 is rotatably mounted on the top of the support frame 51, a bracket 53 is fixedly mounted on the top of the rotating circular plate 52, and a lighting lamp 54 is rotatably mounted on the inner wall of the bracket 53.
[0031] A mounting bracket 41 is fixedly installed on the top of the movable plate 1. A rotating shaft 45 is rotatably mounted on the outer wall of the mounting bracket 41. One end of the outer wall of the rotating shaft 45 is fixedly connected to a cross-shaped plate 46. A second gear 44 is fixedly sleeved on the outer wall of the rotating shaft 45. A first motor 42 is fixedly installed on the outer wall of the mounting bracket 41. The output shaft of the first motor 42 passes through the outer wall of the mounting bracket 41 and is fixedly mounted with a first gear 43. The first gear 43 meshes with the second gear 44. When the first gear 43 rotates, it can drive the second gear 44 and the rotating shaft 45 to rotate. Figure 3 It can be seen that the diameter of the first gear 43 is smaller than that of the second gear 44, and the second gear 44 has more teeth. Therefore, when the first gear 43 rotates, the rotation speed of the second gear 44 and the cross plate 46 can be reduced, which can more accurately adjust the angle of the detection component 4, making it easier for the thermal imaging detector 49 to perform detailed detection, and improving the accuracy and operability of the detection.
[0032] A mounting plate 413 is fixedly installed on the outer wall of the cross-shaped plate 46. A second motor 414 is fixedly installed on the outer wall of the mounting plate 413. The output shaft of the second motor 414 passes through the outer wall of the mounting plate 413 and is fixedly connected to the second bevel gear 412. The second motor 414 can drive the second bevel gear 412 to rotate. Four extended sliding plates 48 are respectively movably inserted into the inner walls of four sliding grooves 47. A control panel 416 is fixedly installed on the outer wall of the mounting frame 41. The control panel 416 is electrically connected to four thermal imaging detectors 49. The detection results of the thermal imaging detectors 49 can be fed back to the control panel 416 through electrical signals, thereby revealing the area of water seepage in the pipe segment.
[0033] Figures 1-7 The second embodiment is shown. The main difference from the first embodiment is that two rotating rods 55 are fixedly installed on both sides of the outer wall of the lighting lamp 54. One end of the outer wall of each of the two rotating rods 55 is rotatably connected to the bracket 53. One end of the outer wall of one of the two rotating rods 55 passes through the outer wall of the bracket 53 and is fixedly installed with a worm gear 56.
[0034] A vertical plate 57 is fixedly installed on the outer wall of the bracket 53. A worm gear 58 is rotatably installed on one side of the outer wall of the vertical plate 57. The worm gear 58 is meshed with a worm wheel 56. When the worm gear 58 is rotated, it can drive the worm wheel 56 to rotate. The worm wheel 56 drives the rotating rod 55 to rotate. The rotating rod 55 then drives the lighting lamp 54 to rotate. At the same time, the worm wheel 56 and worm gear 58 have self-locking properties, which can prevent the lighting lamp 54 from rotating after the angle is adjusted.
[0035] The support frame 51 is fixedly connected to the movable plate 1. A handle 3 is fixedly installed on one side of the outer wall of the movable plate 1. The position of the device can be easily adjusted by the handle 3 and the movable wheel 2, so that the pipe segments in different areas can be inspected.
[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0037] During operation, the device is moved within the tunnel by the handle 3 and the moving wheels 2. When it is necessary to inspect the tunnel segments, the second motor 414 is first turned on. The second motor 414 drives the second bevel gear 412 to rotate, and the four first bevel gears 411 meshing with the second bevel gear 412 will rotate accordingly, thereby causing the threaded screw 415 to rotate within the slide groove 47. Since the threaded screw 415 is threadedly connected to the extension slide plate 48, the extension slide plate 48 will extend outward along the slide groove 47, and the thermal imaging detector 49 mounted on the extension slide plate 48 will also move accordingly, allowing the thermal imaging detector 49 to move closer to the tunnel segments, shortening the inspection distance and making it easier for the thermal imaging detector 49 to detect water seepage areas in the tunnel segments. This improves the detection effect of the thermal imaging detector 49. Then, the first motor 42 is turned on, and the output shaft of the first motor 42 drives the first gear 43 to rotate. Since the first gear 43 meshes with the second gear 44, it drives the rotating shaft 45 and the cross plate 46 to rotate, so that the detection component 4 can scan and detect the pipe segment from all directions, thereby further improving the detection effect of the pipe segment. When the thermal imaging detector 49 detects the water seepage area, it sends an electrical signal to the control panel 416 to know the water seepage area. Then, by rotating the circular plate 52, the angle of the lighting lamp 54 in the horizontal direction is adjusted, and by rotating the worm gear 58, the angle of the lighting lamp 54 in the vertical direction is adjusted, so that the beam of the lighting lamp 54 rotates to the water seepage area, thereby allowing for clearer observation of the detection results and improving the accuracy of the detection.
