[0001] The utility model relates to the technical field of camera support bases, in particular to a sliding shaft base for a highway tunnel camera which is easy to install and maintain. Background Art

[0002] With the rapid development of highway construction in my country, tunnels, as an essential component of highways, are becoming increasingly critical for the stability and efficiency of their security monitoring systems. Highway tunnel cameras, as core equipment in monitoring systems, face a significant impact on monitoring effectiveness and subsequent maintenance efficiency, particularly with their mounting bases.

[0003] Currently, traditional camera mounts on the market mostly use manual operation modes for camera adjustment. Their complex mechanical structures require workers to frequently manually adjust the camera angle and focal length, making it difficult to quickly and accurately capture the desired surveillance footage. Furthermore, traditional mounts often rely on multiple screws or clips for camera fixation, requiring each clip to be loosened and removed individually during disassembly. This complex disassembly process can increase maintenance time and requires specialized tools. In the specialized environment of highway tunnels, workers are exposed to confined spaces and traffic for extended periods. The complex disassembly process increases the risk and difficulty of maintenance work, extending the repair cycle for equipment failures and preventing the timely maintenance of the surveillance system. Therefore, those skilled in the art have provided a sliding-axis mount for highway tunnel cameras that is easy to install and maintain, addressing the issues raised in the aforementioned background technology.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-4 , the utility model provides a technical solution:

[0026] A sliding-axis base for a highway tunnel camera that is easy to install and maintain, comprising:

[0027] A sliding-axis base body 1 is provided with mounting assemblies at both ends of the sliding-axis base body 1. The mounting assemblies include a first mounting block 11, a second mounting block 12, and a mounting plate 13. The mounting plate 13 is provided with mounting threaded holes 14. The first mounting block 11 is fixedly connected to both ends of the sliding-axis base body 1, the second mounting block 12 is fixedly connected to the mounting plate 13, and the first mounting block 11 is rotatably connected to the second mounting block 12.

[0028] When installing the sliding-axis base body 1, the first mounting block 11 and the second mounting block 12 are rotated to a suitable angle by rotating the connection structure so that the mounting plate 13 fits against the tunnel wall. Bolts are passed through the mounting threaded holes 14 on the mounting plate 13 to fix the mounting plate 13 at a preset mounting position on the tunnel wall, completing the initial fixation of the base body. Since some highway tunnels have a certain curvature, the sliding-axis base body 1 can be adjusted for installation.

[0029] A support block 2 is provided on the sliding shaft base body 1, and an adjustment mechanism for driving the installation frame 3 to rotate is installed on the support block 2. The adjustment mechanism includes a first servo motor 15, a second servo motor 16, a first connecting block 17, a second connecting block 18 and a rotating rod 19. A first mounting groove 20 is provided in the support block 2, the first servo motor 15 is installed in the first mounting groove 20, and the output end of the first servo motor 15 is connected to the first connecting block 17, the first connecting block 17 and the second connecting block 18 are connected through the rotating rod 19, the second servo motor 16 is installed on the first connecting block 17, and the output end of the second servo motor 16 is connected to the extending end of the rotating rod 19 passing through the first connecting block 17, the second connecting block 18 is connected to the installation frame 3, a limiting block 21 is connected to the first connecting block 17, a limiting groove 22 is provided on the support block 2, the limiting block 21 is slidably connected in the limiting groove 22, and a ball 23 is rotatably connected to the limiting block 21, and the ball 23 is slidably connected in the limiting groove 22;

[0030] During horizontal rotation adjustment, the first servo motor 15 is activated, and its output drives the first connecting block 17 to rotate. Since the first connecting block 17 is connected to the second connecting block 18 via the rotating rod 19, the mounting frame 3 and the camera body 4 can be rotated horizontally, thereby adjusting the horizontal angle range of monitoring. When the first connecting block 17 rotates, the limit block 21 slides within the limit slot 22. The provision of the ball bearing 23 reduces frictional resistance, making the adjustment process smoother and reducing the load on the first servo motor 15.

[0031] During vertical pitch adjustment, the second servo motor 16 is started, and its output end drives the rotating rod 19 to rotate, thereby driving the second connecting block 18 and the mounting frame 3 to perform vertical pitch movement to achieve vertical angle adjustment of the camera.

[0032] The mounting frame 3 is provided with a fixing assembly for fixing the camera body 4, which includes a threaded rod 5, a rotating handle 6 and a clamping plate 7. The threaded rod 5 is threadedly connected to the mounting frame 3, the rotating handle 6 is fixedly connected to one end of the threaded rod 5, and the clamping plate 7 is rotatably connected to the other end of the threaded rod 5. A rubber layer 24 is provided in the clamping plate 7 and the mounting frame 3. The rubber layer 24 is in contact with the camera body 4. A cable 29 is connected to the camera body 4. The cable 29 provides working power to the camera body 4 to ensure normal startup and operation of the device and is responsible for transmitting the video signal to the storage device or monitoring center;

[0033] Place the camera body 4 in the mounting frame 3, rotate the handle 6, and drive the threaded rod 5 to transmit on the mounting frame 3, so that the clamping plate 7 moves toward the camera body 4 until the rubber layer 24 on the clamping plate 7 is in close contact with the camera body 4, completing the quick fixation. The clamping plate 7 and the rubber layer 24 in the mounting frame 3 can increase friction when fixing the camera, thereby improving the fixation stability.

[0034] A distance sensor 8 is installed at the lower end of the support block 2, a temperature and humidity sensor 9 is installed on one side of the installation frame 3, and a monitoring fill light 10 is installed on the support block 2.

[0035] Furthermore, a second mounting groove 25 is provided on the support block 2, and a battery 26 and a controller 27 are installed in the second mounting groove 25. The controller 27 is electrically connected to the battery 26, the ranging sensor 8, the temperature and humidity sensor 9, the monitoring fill light 10, the first servo motor 15 and the second servo motor 16 respectively. An alarm 28 is installed on the support block 2, and the alarm 28 is electrically connected to the controller 27.

[0036] Distance sensor 8 detects the distance between camera body 4 and the road surface. Temperature and humidity sensor 9 collects temperature and humidity data from the tunnel environment and transmits this data to controller 27. Controller 27 analyzes and determines the sensor data based on preset thresholds. If the temperature and humidity exceed the normal range, controller 27 controls alarm 28 to sound an alert to alert maintenance personnel. Simultaneously, monitoring fill light 10 automatically turns on and off based on ambient light conditions, improving monitoring image quality. Battery 26 provides power for the entire system, ensuring stable operation in the tunnel environment.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
