Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel monitoring technology, and in particular to a camera for tunnels. Background Technology
[0002] Highway tunnels are passageways specifically designed for automobile transportation. With the development of society, economy, and production, a large number of expressways have emerged, which has placed higher standards on road construction technology, requiring straight routes, gentle slopes, and wide road surfaces. Therefore, when roads pass through mountainous areas, the old method of winding through mountains has often been replaced by tunnels. The construction of tunnels plays an important role in improving the technical condition of highways, shortening travel distances, increasing transportation capacity, and reducing accidents.
[0003] In existing technologies, tunnel cameras are all fixed to the inner wall of the tunnel. When an accident occurs inside the tunnel, if the accident is within the camera's monitoring range, the accident can be seen directly. However, if the accident occurs outside the camera's monitoring range, the camera cannot move to the accident area to obtain the accident information. Therefore, a tunnel camera is proposed. Utility Model Content
[0004] To address at least one of the aforementioned technical shortcomings, this utility model provides a tunnel camera, comprising: a panoramic camera, a sliding rod, a threaded rod, a reducer, and a servo motor. The mounting base of the panoramic camera has two parallel through holes, and a through threaded hole is located between the two through holes. The sliding rod is movably connected inside the through holes, and the threaded rod is threadedly connected inside the threaded hole. The end of the threaded rod is driven by the reducer and the servo motor.
[0005] Furthermore, the slide bar is composed of several splicing rods joined end to end, and adjacent splicing rods are connected by threaded cylinders and screws.
[0006] Furthermore, the outer ends of the splicing rods at both ends are coaxially provided with concave limiting grooves, and also include mounting plates that are fixed to the inner wall of the tunnel by bolts. Both ends of the slide rod are provided with fixing plates, and the fixing plates are provided with two fixing grooves that engage with the limiting grooves. The middle of the fixing plate is provided with a rotating hole that is rotatably connected to the threaded rod. Both ends of the fixing plate are provided with at least one countersunk hole, and the countersunk hole is fixedly connected to the mounting plate by screws.
[0007] Furthermore, the reducer and servo motor are fixedly connected to the mounting plate.
[0008] Furthermore, it also includes a slide rail that is slidably connected to the mounting base of the panoramic camera.
[0009] Furthermore, the slide rail is composed of several Z-shaped plates evenly distributed on both sides of the mounting base of the panoramic camera, spliced together end to end. The cross-section of the Z-shaped plate is a right-angled Z-shaped structure. Several mounting holes are evenly opened on the horizontal surface of one end of the Z-shaped plate. The Z-shaped plate is fixed to the inner wall of the tunnel by screws passing through the mounting holes. The inner surface of the horizontal surface of one end of the Z-shaped plate is slidably connected to the mounting base of the panoramic camera. Beneficial effects
[0010] When adjusting the position of the panoramic camera inside the tunnel, the servo motor rotates, which drives the reducer to rotate, which in turn drives the threaded rod to rotate. This causes the threaded rod to engage with the threaded hole, allowing the mounting base of the panoramic camera to move on the slide rod, thereby adjusting the position of the panoramic camera.
[0011] The panoramic camera mounting base has a square planar structure. The inner surface of the horizontal plane at one end of the Z-shaped plate abuts against the surface of the panoramic camera mounting base to form a sliding structure. The two Z-shaped plates respectively form a sliding structure with the surface of the panoramic camera mounting base from both sides, allowing the panoramic camera to move in the gap between the two Z-shaped plates. At the same time, the two Z-shaped plates provide support, thereby reducing the stress on the sliding rod and threaded rod.
[0012] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation
[0021] Please refer to Figures 1 to 7 ;
[0022] This embodiment provides a tunnel camera, see reference. Figures 1 to 5 The system includes: a panoramic camera 1, a sliding rod 2, a threaded rod 3, a reducer 301, and a servo motor 302. The mounting base of the panoramic camera 1 has two parallel through holes 101, and a through threaded hole 102 is provided in the middle of the two through holes 101. The sliding rod 2 is movably connected inside the through hole 101, and the threaded rod 3 is threadedly connected inside the threaded hole 102. The end of the threaded rod 3 is driven by the reducer 301 and the servo motor 302.
[0023] In practice, when adjusting the position of the panoramic camera 1 in the tunnel, the servo motor 302 rotates, drives the reducer 301 to rotate, drives the threaded rod 3 to rotate, so that the threaded rod 3 engages with the threaded hole 102, and causes the mounting base of the panoramic camera 1 to move on the slide rod 2, thereby adjusting the position of the panoramic camera 1.
[0024] The position of the panoramic camera 1 is controlled by controlling the number of rotations of the servo motor 302.
[0025] The control technology for the servo motor 302 adopts existing technology.
[0026] Further reference Figure 3 The slide bar 2 is composed of several splicing rods 201 spliced end to end, and adjacent splicing rods 201 are connected by threaded cylinders and screws.
[0027] In practical implementation, by setting up several splicing rods 201, the slide rod 2 can be assembled by assembling several splicing rods 201, making the slide rod 2 more convenient to transport and install.
[0028] Further reference Figure 2 and Figure 3The outer ends of the splicing rods 201 at both ends are coaxially provided with concave limiting grooves 202. It also includes an installation plate 4 that is fixed to the inner wall of the tunnel by bolts. Both ends of the slide rod 2 are provided with fixing plates 203. The fixing plates 203 are provided with two fixing grooves 204 that engage with the limiting grooves 202. The middle part of the fixing plate 203 is provided with a rotating hole 205 that is rotatably connected to the threaded rod 3. Both ends of the fixing plate 203 are provided with at least one countersunk hole 206. The countersunk hole 206 is fixedly connected to the installation plate 4 by screws.
[0029] In practice, during installation, the mounting plate 4 is first fixed to the inner wall of the tunnel. After assembling the slide rod 2, one end of the slide rod 2 is fixed to the mounting plate 4 through the fixing plate 203, and the other end of the slide rod 2 is also fixed to the mounting plate 4 through the fixing plate 203. At the same time, the threaded rod 3 needs to be installed.
[0030] Furthermore, the reducer 301 and the servo motor 302 are fixedly connected to the mounting plate 4.
[0031] In practice, after the threaded rod 3 is installed, the reducer 301 and the servo motor 302 are fixed to the mounting plate 4. The output end of the servo motor 302 drives the input end of the reducer 301, and the output end of the reducer 301 drives the threaded rod 3.
[0032] Further reference Figure 6 and Figure 7 It also includes a slide rail 5 that is slidably connected to the mounting base of the panoramic camera 1.
[0033] In practical implementation, the sliding rail 5 reduces the pressure on the sliding rod 2 and threaded rod 3, and slows down the bending deformation of the sliding rod 2 and threaded rod 3 caused by the panoramic camera 1.
[0034] Further reference Figure 7 The slide rail 5 is composed of several Z-shaped plates 501 evenly distributed on both sides of the mounting base of the panoramic camera 1, spliced together end to end. The cross-section of the Z-shaped plate 501 is a right-angled Z-shaped structure. Several mounting holes 511 are evenly opened on the horizontal surface of one end of the Z-shaped plate 501. The Z-shaped plate 501 is fixed to the inner wall of the tunnel by screws passing through the mounting holes 511. The inner surface of the horizontal surface of one end of the Z-shaped plate 501 is slidably connected to the mounting base of the panoramic camera 1.
[0035] In practical implementation, the mounting base of the panoramic camera 1 has a square planar structure. The inner surface of the horizontal plane of one end of the Z-shaped plate 501 abuts against the surface of the mounting base of the panoramic camera 1 to form a sliding structure. The two Z-shaped plates 501 respectively form a sliding structure with the surface of the mounting base of the panoramic camera 1 from both sides, so that the panoramic camera 1 can move in the gap between the two Z-shaped plates 501. At the same time, it is supported by the two Z-shaped plates 501, thereby reducing the stress on the sliding rod 2 and the threaded rod 3.
