Description

Technical Field

[0001] This utility model relates to the technical field of sound and light alarm equipment, and in particular to a sound and light alarm device for vehicles passing through tunnels. Background Technology

[0002] With the rapid development of transportation, tunnels are being used more and more widely in transportation networks. Inside tunnels, due to the relatively enclosed space and limited lighting, there are certain safety hazards for vehicles. When a vehicle passes through a tunnel, especially in special circumstances such as speeding or breakdowns, it is necessary to promptly alert other people and vehicles inside the tunnel to ensure traffic safety.

[0003] Some existing tunnel alarm devices lack flexibility in the installation location of radar sensors, making it difficult to adjust according to actual tunnel conditions and vehicle traffic characteristics. This can easily lead to missed alarms and pose safety hazards. Therefore, we propose a tunnel vehicle audible and visual alarm device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vehicle-passing sound and light alarm device for tunnels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vehicle-passing audible and visual alarm device for tunnels includes a fixed base with two fixed plates fixedly installed on both sides. A controller is fixedly installed on the front side of the fixed base, and an audible and visual alarm is installed on the front side of the controller. A movable hole is opened at the top of the fixed base. An adjusting seat one and an adjusting seat two are slidably installed on the rear inner wall of the movable hole. The adjusting seat two is located to the right of the adjusting seat one. The top end of the adjusting seat one and the bottom end of the adjusting seat two both extend to the outside of the fixed base and are fixedly installed with mounting plates. A mounting base is installed on the front side of the mounting plate through a detachable structure. A radar sensor is fixedly installed on the front side of the mounting base. A drive mechanism for moving the adjusting seat one and the adjusting seat two is provided in the movable hole, and the radar sensor is electrically connected to the controller.

[0007] Preferably, the driving mechanism includes a rack, a rotating shaft, and a rotating gear. The rack is fixedly mounted on the front side of the adjusting seat, the rotating shaft is rotatably mounted on the inner walls of both sides of the moving hole, and the rotating gear is fixedly mounted on the rotating shaft, and the rotating gear meshes with the rack.

[0008] Preferably, the drive mechanism further includes a second spur rack, a second rotating shaft, and a second rotating gear. The second spur rack is fixedly installed on the front side of the second adjusting seat. The same second rotating shaft is rotatably installed on the inner walls of both sides of the moving hole. The second rotating shaft is located below the first rotating shaft. The second rotating gear is fixedly installed on the second rotating shaft, and the second rotating gear meshes with the second spur rack.

[0009] Preferably, a control box is fixedly installed on one side of the fixed base, and one end of the first rotating shaft and the second rotating shaft both extend into the box. The control box is equipped with a rotating mechanism, and a transmission mechanism is provided between the rotating mechanism and the first rotating shaft and the second rotating shaft.

[0010] Preferably, the rotating mechanism includes a drive motor and a transmission shaft. The drive motor is fixedly mounted on the bottom of the control box, and the transmission shaft is rotatably mounted on the top and bottom inner walls of the control box. The output shaft of the drive motor is fixedly connected to the transmission shaft.

[0011] Preferably, the transmission mechanism includes a driving bevel gear and a driven bevel gear. Two driving bevel gears are fixedly installed on the transmission shaft, and a driven bevel gear is fixedly installed at one end of both the rotating shaft one and the rotating shaft two. The driving bevel gear meshes with the corresponding driven bevel gear, and both driven bevel gears are located between the two driving bevel gears.

[0012] Preferably, the mounting base has a round hole, and a fixing screw is fixedly installed on the front side of the mounting plate, with a fixing nut threaded through the fixing screw.

[0013] Preferably, two limiting grooves are provided on the rear inner wall of the moving hole, and limiting seats are fixedly installed on the rear sides of both adjusting seat one and adjusting seat two, and the limiting seats are slidably connected to the corresponding limiting grooves.

[0014] The beneficial effects of this utility model are:

[0015] 1. The fixing plate facilitates the installation of the fixing seat on the side arm of the tunnel. The rotating motor can drive the adjusting seat one to move upward and the adjusting seat two to move downward, thereby adjusting the distance between the two radar sensors and avoiding the situation where the radar sensor installation position causes the car to miss the alarm.

[0016] 2. When a vehicle passes one side of the two radar sensors in the tunnel, the radar sensors can detect the vehicle passing by and send a signal to the controller. The controller can then activate the audible and visual alarm to issue a warning. The audible and visual alarm can be automatically turned off after the warning is set.

[0032] When a vehicle passes one side of the two radar sensors 206 in the tunnel, the radar sensors 206 can detect the vehicle passing by and send a signal to the controller 102. The controller 102 can then activate the audible and visual alarm 103 to issue a warning. After the warning is set, the audible and visual alarm 103 can be automatically turned off. With the cooperation of the fixing nut 802 and the fixing screw 801, it is easy to fix and unfix the mounting base 205 and the radar sensor 206, thereby facilitating the disassembly, assembly, and maintenance of the audible and visual alarm 103.
