[0023] Highway tunnels are an indispensable part of modern transportation construction. They bring convenience to people's travel, but they also pose various safety hazards. Among them, parking due to vehicle failure in the tunnel is most likely to cause secondary accidents.

[0024] It is well known that the air in tunnels is not smooth, which can easily lead to the accumulation of smoke and automobile exhaust, thus posing a huge safety hazard. In order to solve this problem, the current common method is to install surveillance cameras at equal intervals in high-speed tunnels for inspection and control, and cooperate with loudspeakers to guide the evacuation of vehicles and personnel in the tunnel. However, fixed-installed cameras have strong monitoring blind spots and cannot allow back-end management personnel to detect problems in the first time.

[0025] Reference Figures 1 to 3 The present application provides a highway tunnel inspection device, comprising two parallel anti-collision guardrails 1, which are used to be installed on the inner wall of the tunnel. The anti-collision guardrails 1 are of the same length as the highway tunnel. Inspection devices for installing cameras and speakers are provided on the two anti-collision guardrails 1. The inspection device comprises a first positioning box body 3 and a second positioning box body 4. The first positioning box body 3 and the second positioning box body 4 are connected by an elastic clamping mechanism. A driven mechanism is provided in the first positioning box body 3, and an active mechanism is provided in the second positioning box body 4. The elastic clamping mechanism is used to apply a force to the first positioning box body 3 and the second positioning box body 4 to move closer to each other, so that the driven mechanism and the active mechanism are clamped on both sides of the two anti-collision guardrails 1. A pan-tilt plate 5 is installed on one side of the inspection device, and a plurality of groups of ear seats 6 for installing inspection cameras and speakers are provided on the outer side surface of the pan-tilt plate 5.

[0026] During operation, the elastic clamping mechanism clamps the active mechanism and the driven mechanism on the outside of the two anti-collision guardrails 1. The active mechanism works to drive the inspection device to move along the two anti-collision guardrails 1, thereby realizing the camera and speaker on the inspection device to patrol back and forth in the tunnel. This inspection device is not fixed at a certain place in the tunnel, it can move flexibly, so there are fewer blind spots in monitoring.

[0027] In some embodiments, a first groove 31 is formed on the inner side of the first positioning box body 3 for avoiding the anti-collision guardrail 1, and a second groove 41 is formed on the inner side of the second positioning box body 4 for avoiding the anti-collision guardrail 1. The first groove 31 and the second groove 41 play a role of avoiding, preventing the first positioning box body 3 and the second positioning box body 4 from directly contacting the anti-collision guardrail 1.

[0028] The first positioning box body 3 and the second positioning box body 4 are both rectangular box-shaped structures.

[0029] In some embodiments, the active mechanism includes an active rotating shaft 9 located in the second positioning box body 4, and the upper and lower ends of the active rotating shaft 9 are respectively rotatably connected to the second positioning box body 4, and an active rubber wheel 10 is installed on the active rotating shaft 9 for fitting the outer cylindrical surface of the anti-collision guardrail 1. A motor 100 is installed on the top of the second positioning box body 4, and the upper end of the active rotating shaft 9 extends out of the second positioning box body 4 and is connected to the power output shaft of the motor 100. The driven mechanism includes a driven rotating shaft 7 located in the first positioning box body 3, and the upper and lower ends of the driven rotating shaft 7 are respectively rotatably connected to the first positioning box body 3, and a driven rubber wheel 8 is installed on the driven rotating shaft 7 for fitting the outer cylindrical surface of the anti-collision guardrail 1.

[0030] During operation, the motor 100 drives the active rotating shaft 9 to rotate, and the active rubber wheel 10 rotates, and the entire inspection device is driven to move along the anti-collision guardrail 1 under the action of friction.

[0031] In some embodiments, an annular groove for matching with the anti-collision guardrail 1 is provided on the active rubber wheel 10 and the driven rubber wheel 8. In this way, the active rubber wheel 10 and the driven rubber wheel 8 are more closely matched with the anti-collision guardrail 1.

[0032] In some embodiments, the elastic clamping mechanism includes two spring shafts 11 arranged in a vertically corresponding manner. A through hole is provided in the second positioning box body 4. One end of the spring shaft 11 passes through the through hole and is fixedly connected to the first positioning box body 3. An anti-drop cap 12 is provided at the other end of the spring shaft 11. The spring shaft 11 is loosely fitted with the through hole. A spring 13 is sleeved on the spring shaft 11 and is pressed between the anti-drop cap 12 and the second positioning box body 4. The spring 13 is used to apply a force to clamp the active rubber wheel 10 and the driven rubber wheel 8 to the two sides of the anti-collision guardrail 1.

[0033] In some embodiments, the anti-collision guardrail 1 is fixed to the inner wall of the tunnel through the support rod 2.

[0034] In some embodiments, the bracket link 2 is an L-shaped structure formed by a single bending operation. When the first positioning box 3 and the second positioning box 4 are clamped on the anti-collision guardrail 1, a gap is set between the first positioning box 3 and the second positioning box 4 to avoid the bracket link 2.

[0035] In some embodiments, a magnetic switch is mounted on the back of the first positioning box 3. This magnetic switch interfaces with the control terminal of the motor 100 to control the forward and reverse rotation of the motor 100. Magnet modules corresponding to the magnetic switches are mounted on the walls at both ends of the tunnel. When the inspection device moves to the point where the magnetic switch and the magnet module interact, the motor 100 rotates in reverse, preventing the inspection device from detaching from the anti-collision guardrail 1. Furthermore, a power storage assembly interfaced with the motor 100 is mounted within the second positioning box 4.

[0036] In other embodiments, push-type position switches are installed at both ends of the anti-collision guardrail 11, and the push-type position switches are connected to the control end of the motor 100 via wires to control the forward and reverse rotation of the motor 100. In addition, the power storage assembly connected to the motor 100 is preferably installed in the first positioning box 3.

[0037] During installation, the first positioning box body 3 and the second positioning box body 4 are pulled apart so that the adjacent driven rubber wheels 8 and the active rubber wheels 10 are placed on both sides of the anti-collision guardrail 1. Then the first positioning box body 3 and the second positioning box body 4 are loosened. Under the resetting action of the spring 13, the driven rubber wheel 8 and the active rubber wheel 10 can be clamped on the corresponding anti-collision guardrail 11, and the motor 100 drives the active shaft 9 to rotate, thereby realizing the walking inspection of the entire inspection device.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are contradictory.

[0039] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
