Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described 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 work shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] Please refer to Figures 1 to 3 As shown, the present invention provides a monitoring and early warning device during tunnel operation, including a tunnel body 1. One side of the inner wall of the tunnel body 1 is fixedly connected with a vertical beam 2, and one side of the vertical beam 2 is provided with a mounting plate 4 through a screw mechanism 3. The bottom of the mounting plate 4 is provided with a water level monitor 5 through a clamping component. The water level monitor 5 uses radar technology to measure the water level. By emitting radar pulses and receiving the signals reflected by the water surface, the water level height in the tunnel body 1 is measured;

[0025] The clamping component includes a vertical plate 6 penetrating through the top of the mounting plate 4. An activity slot 7 is opened inside the vertical plate 6, and stop blocks 8 are slidably arranged on both sides of the inner wall of the activity slot 7. A spring 9 is fixedly connected between the two stop blocks 8. Convex blocks 10 penetrating through the outside of the vertical plate 6 are fixedly connected to the opposite sides of the two stop blocks 8. When the convex blocks 10 are located outside the vertical plate 6, the water level monitor 5 can be clamped and installed under the mounting plate 4. The bottom of the vertical plate 6 is threadedly connected to the top of the water level monitor 5, and the bottom of the convex block 10 is movably connected to the top of the mounting plate 4;

[0026] The screw mechanism 3 includes a motor 31 fixed to the top of the inner wall of the vertical beam 2. The output end of the motor 31 is fixedly connected with a screw rod 32. The bottom end of the screw rod 32 is rotatably connected to the bottom of the inner wall of the vertical beam 2. A movable plate 33 is threadedly connected to the surface of the screw rod 32. One side of the movable plate 33 extending outside the vertical beam 2 is fixedly connected with one side of the mounting plate 4, and the other side of the movable plate 33 is slidably connected to the inner wall of the vertical beam 2.

[0027] With the above structure, the water level monitor 5 is arranged at the top of the tunnel body 1, and the installation position is safer, avoiding collisions with passing vehicles. While ensuring safety, the lead screw mechanism 3 can drive the water level monitor 5 to move downward to the lower part of the tunnel, and the water level monitor 5 can be disassembled and maintained through the clamping component, which has better practicability.

[0028] Embodiment 2

[0029] On the basis of Embodiment 1, please refer to Figure 1 and Figure 4 As shown, a cross beam 11 is fixedly connected between the two sides of the top of the tunnel body 1, and an audible and visual alarm 12 is fixedly connected to the bottom of the cross beam 11 through a mounting block. When the water level is detected to be too high, the audible and visual alarm 12 is used for audible and visual alarm. The bottom of the cross beam 11 is fixedly connected with a housing 13 through a mounting block, and a servo motor 14 is fixedly connected to the top of the inner wall of the housing 13. The output end of the servo motor 14 is fixedly connected with a fixed rod 15, and a monitoring camera 16 is fixedly connected to one end of the fixed rod 15 extending to the bottom of the housing 13.

[0030] With the above structure, the servo motor 14 can drive the monitoring camera 16 to rotate for monitoring, increasing the monitoring range inside the tunnel and improving the monitoring effect of the tunnel.

[0031] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited. Conventional equipment adapted to the equipment can be used.

[0032] During use, the water level monitor 5 is located at the top of the vertical beam 2, and the radar technology is used to monitor the water level inside the tunnel body 1 in real time. When the water level is too high, the audible and visual alarm 12 gives an audible and visual alarm to issue a warning to ensure the safety during tunnel operation. By starting the motor 31, the lead screw 32 is driven to rotate. Under the sliding guidance of the movable plate 33, the mounting plate 4 can drive the water level monitor 5 to move downward on the lead screw 32 to the bottom of the tunnel. Then, by pressing the two convex blocks 10 on both sides, the convex blocks 10 are driven to squeeze the spring 9. After the convex blocks 10 completely enter the movable groove 7, the vertical plate 6 can be pulled out from the mounting plate 4, so that the water level monitor 5 can be disassembled, which is convenient for maintaining the water level monitor 5. Conversely, it can be installed and used. While the water level monitor 5 is monitoring, the monitoring camera 16 monitors the inside of the tunnel body 1 under the cross beam 11 in real time, and the servo motor 14 drives the monitoring camera 16 to rotate left and right, increasing the shooting range of the monitoring camera 16 and making the monitoring more comprehensive.

[0033] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
