Description

Technical Field

[0001] The present application relates to the field of data collection technology, and specifically to a traffic data collection device. Background Art

[0002] Traffic data collection devices refer to a combination of equipment used to collect and process traffic information in real time. These devices are widely used in traffic management and intelligent transportation systems. They are designed to collect key data such as traffic flow, speed, vehicle type, road conditions, etc. on the road in real time, and include components such as cameras.

[0003] At present, some outdoor data collection cameras are exposed to the outside. These cameras are greatly affected by rain, snow and hail. In particular, the impact of hail may damage the lens surface, causing scratches or cracks and affecting image quality. Another part is fixedly installed in a protective frame. Although it can be effectively protected, due to the space limitation in the protective frame, it is not conducive to disassembling and installing the camera in the protective frame for upgrading and maintenance. Utility Model Content

[0004] In view of this, the purpose of the present invention is to solve the shortcomings of the background technology and to propose a traffic data collection device to solve the problems existing in the prior art.

[0005] To achieve the above purpose, the present invention provides a traffic data collection device, including a base, the top of the base is fixedly connected to a fixed platform, the top of the base is provided with a wire mesh, the top of the inner wall of the fixed platform is fixedly connected to a protective frame, the inner surface of the protective frame is slidably connected to a slide, the outer surface of the slide is fixedly installed with a data collection camera, the protective frame is provided with a push-type storage mechanism for adjusting the position of the data collection camera, and the slide is provided with a slide groove for cooperating with the push-type storage mechanism to stably push the data collection camera.

[0006] Preferably, the push-type storage mechanism includes a damping shaft fixedly connected to the outer surface of the protective frame, and the outer surface of the damping shaft is rotatably connected to a swing arm. Through the push-type storage mechanism, the data acquisition camera can be adjusted to a suitable position at an appropriate time to cope with the corresponding scene.

[0007] Preferably, the bottom of the swing arm is fixedly connected to a handle, and the inner surface of the swing arm is rotatably connected to a connecting shaft.

[0008] Preferably, the outer surface of the connecting shaft is rotatably connected to a driving bar, the inner side of the slide is fixedly penetrated by a guide rod, and the outer surface of the guide rod is rotatably connected to the end of the driving bar away from the connecting shaft.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The combination of the slide and the drive bar of this traffic data collection device enables the camera to adjust its position within the protective frame as needed, so that the camera can be easily moved out of the protective frame when maintenance or upgrade is required without completely disassembling the frame itself. Therefore, upgrades and maintenance can be completed in a relatively open environment, effectively reducing the difficulty of maintenance.

[0011] 2. In this traffic data collection device, the data collection camera is normally located inside the protective frame. The protective frame effectively protects the camera to reduce the impact of rain, snow, and hail. In particular, it can reduce the risk of hail directly hitting the camera surface, reducing the risk of image quality damage caused by scratches or cracks on the camera surface.

[0016] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0017] See also Figure 1-3 A traffic data collection device includes a base 1, a fixed platform 2 is fixedly connected to the top of the base 1, a wire mesh 3 is provided on the top of the base 1, a protective frame 4 is fixedly connected to the top of the inner wall of the fixed platform 2, a slide 5 is slidably connected to the inner surface of the protective frame 4, a data collection camera 6 is fixedly installed on the outer surface of the slide 5, and a push-type storage mechanism for adjusting the position of the data collection camera 6 is provided on the protective frame 4.

[0018] Through the above technical solution, when the device is in use, the data acquisition camera 6 is movably installed in the protective frame 4, and the position of the data acquisition camera 6 can be adjusted according to needs (adjusted to inside or outside the protective frame 4). During the operation of the camera, the wire mesh 3 always provides a certain degree of enclosure protection for its position.

[0019] Specifically, the push-type storage mechanism includes a damping shaft 7 fixedly connected to the outer surface of the protection frame 4, and the outer surface of the damping shaft 7 is rotatably connected to the swing arm 8.

[0020] Through the above technical solution, the damping shaft 7 has certain damping characteristics. After the swing arm 8 rotates along the damping shaft 7 to a corresponding angle, it can remain relatively stable if it is no longer subjected to additional force.

[0021] Specifically, the bottom of the swing arm 8 is fixedly connected to the handle 9, and the inner surface of the swing arm 8 is rotatably connected to the connecting shaft 10.

[0022] Through the above technical solution, when the handle 9 is held and turned, it will link the swing arm 8 to rotate, and the swing arm 8 will first rotate along the damping shaft 7.

[0023] Specifically, the outer surface of the connecting shaft 10 is rotatably connected to the driving bar 11, the inner side of the slide 5 is fixedly penetrated by a guide rod 12, and the outer surface of the guide rod 12 is rotatably connected to the end of the driving bar 11 away from the connecting shaft 10.

[0024] Through the above technical solution, during the rotation of the swing arm 8, it will drive the driving bar 11 through the connecting shaft 10, so that the driving bar 11 is deflected.

[0025] Working principle: When the device is in use, the data acquisition camera 6 collects traffic data at this location. During this period, the wire mesh 3 can provide effective enclosure protection on the periphery of the camera to reduce the impact and collision of external objects on the fixed platform 2 and the data acquisition camera 6. Under normal circumstances, the data acquisition camera 6 is inside the protective frame 4. At this time, the protective frame 4 effectively protects the camera to reduce the impact of rain, snow and hail, especially to reduce the direct impact of hail on the camera surface, and reduce the risk of image quality damage caused by scratches or cracks on the camera surface. When upgrading and maintaining the camera, due to the limitation of the internal space of the protective frame 4, it is difficult to upgrade the data acquisition camera inside the protective frame 4. The camera 6 is operated. At this time, you can hold the handle 9 and turn it to allow the swing arm 8 to rotate along the damping shaft 7. During this process, the swing arm 8 will drive the driving bar 11 through the connecting shaft 10, so that the driving bar 11 is deflected, and the other end of the driving bar 11 will rotate along the guide rod 12, and the guide rod 12 will pull the slide 5 to make the slide 5 slide outward along the inner side of the protective frame 4, that is, the data acquisition camera 6 will move outward synchronously until the main body of the camera is basically exposed, so that the camera can be upgraded and maintained in a relatively open environment, which effectively reduces the difficulty of maintenance. After completing the upgrade and maintenance, the camera is pushed back into the protective frame 4, and the camera can be adjusted to different positions in different scenes.

[0026] Although the embodiments of the present application 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 application, and the scope of the present application is defined by the appended claims and their equivalents.
