Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of road traffic cameras, and particularly to a self-cleaning road traffic camera. Background Art
[0002] With the acceleration of the urbanization process and the rapid development of intelligent transportation systems, road traffic cameras are increasingly widely used. These cameras play a crucial role in traffic monitoring, safety management, road maintenance, etc. However, traditional road traffic cameras are long-term exposed to outdoor environments and often face the invasion of various pollutants such as rain, dust, and oil stains, resulting in their lenses being easily soiled, affecting the imaging quality. This not only reduces the monitoring effect of the cameras but may also have an adverse impact on traffic safety and road management. To solve this problem, self-cleaning road traffic cameras have emerged. Such cameras can automatically remove pollutants on the lens surface to a certain extent through the integration of advanced self-cleaning technologies, maintaining the cleanliness of the lens and the imaging quality.
[0003] A self-cleaning road traffic camera disclosed in the patent publication No. CN117896596A. The camera includes a box body, a mounting component, a cleaning component, and a counterweight. The lens of the camera is located on the front end face of the box body. A linear drive component is installed on the front end face of the box body, and a guide groove is provided on the front end face. During the reciprocating linear motion of the cleaning component, it rotates around the axis of the mounting rod at the same time, thereby wiping and cleaning the lens of the camera. When the cleaning cotton strip is in the reciprocating linear motion, the rotation direction of the mounting rod is opposite, so that the first side and the second side of the cleaning cotton strip are alternately wound around the mounting rod, making both sides of the cleaning cotton strip be utilized, which can improve the utilization rate of the cleaning cotton strip. By adjusting the rotation speeds of the first motor and the second motor, the linear motion speed and the rotation speed of the cleaning component can be adjusted, and then the wiping speed of the cleaning component can be adjusted according to the dirt degree of the lens.
[0004] When the above-mentioned prior art is used, it is necessary to use the first motor and the second motor to rotate to make the cleaning cotton strip move horizontally to clean the surface of the lens. Among them, the first gear needs to cooperate with the driving gear and the driven gear to alternately clean the front and back sides of the cleaning cotton strip. The overall operation is relatively cumbersome. Moreover, the first gear during the movement needs to mesh with the rotating driving gear, and the cooperation difficulty is high. Since both of them are in dynamic changes, it may lead to the failure of the cooperation. Even if the cooperation is successful, a stable transmission relationship cannot be maintained, resulting in the cleaning cotton strip being unable to maintain stable and effective cleaning. And due to the large cooperation difficulty, the gears may generate greater impact and vibration during the meshing process. This vibration not only affects the transmission efficiency of the gears but may also cause damage to the surrounding mechanical structures, thereby increasing the use cost.
[0005] A road traffic monitoring camera is disclosed in the publication number CN108224019A, which includes a base arranged on a road bracket and a monitoring head cooperatively connected with the base. It is characterized in that: two sliding grooves are symmetrically arranged left and right in the base, a through groove is penetrated between the bottoms of the two sliding grooves, and a driving cavity is penetrated between the tops of the two sliding grooves. In the present invention, the monitoring head is fixed safely and stably, and the power transmission stability of the monitoring head is good. When installing the monitoring head, the monitoring head is locked first and then powered, and when disassembling, the monitoring head is powered off first and then unlocked, effectively avoiding electric shock accidents during the installation and disassembly of the monitoring head. The whole device is convenient and fast to operate, greatly increasing the installation and disassembly efficiency of the monitoring head.
[0006] When the above-mentioned prior art is in use, multiple bases are provided, and monitoring probes are correspondingly installed in a detachable manner. Among them, road traffic cameras are basically installed in outdoor environments, exposed to the air, and are easily attached with pollutants such as dust, dirt, rainwater, and insects. These pollutants will block the lens, resulting in blurred and unclear images captured by the camera. In addition, the lack of self-cleaning design means that the camera cannot automatically remove these pollutants and requires manual cleaning and maintenance, which increases the maintenance cost and difficulty. And if the camera cannot work properly due to pollution, then road safety will be threatened. Summary of the Invention
