Description

Technical Field

[0001] This invention relates to the field of monitoring equipment cleaning technology, and in particular to an automatic cleaning device for industrial environment cameras. Background Technology

[0002] In daily production, especially in dusty areas, surveillance cameras in industrial settings are prone to accumulating fog or dust on their lenses, turning high-resolution images into blurry ones. If these obstructions aren't cleaned regularly, the monitoring image will be affected. Manual cleaning is time-consuming and labor-intensive due to the large number of cameras. Patent application number 202021781469.0 discloses a surveillance device with automatic camera cleaning capabilities, including a water inlet, an activated carbon tank, and a water storage tank. The activated carbon tank is fixedly installed at the bottom of the water inlet, and the water storage tank is fixedly connected to the bottom of the activated carbon tank. The beneficial effects of this invention are: simple structure, practical function, and the ability to automatically clean the cameras. The cleaning frequency can be adjusted by setting a program, shortening the cleaning interval in cities with poor air quality. The short cleaning time does not affect the normal operation of the surveillance equipment, and water is only added during initial installation; generally, rainwater filtration meets the water requirements. This invention can improve the normal operation of urban surveillance systems. The wiper blades of the aforementioned camera cleaning devices adhere tightly to the surface to be cleaned through their own elasticity. However, in industrial environments, the metal springs are highly susceptible to corrosion and damage under acidic or alkaline vapor conditions, and the cleaning blades easily lose their elasticity and fail. Furthermore, the existing camera cleaning devices operate on a timed basis and cannot respond promptly to irregular contamination. Therefore, it is necessary to invent an industrial camera cleaning device that can adjust the wiper blade pressure and automatically clean according to the level of contamination. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing an automatic cleaning device for industrial environment cameras, which solves the technical problem that traditional camera cleaning scrapers easily lose elasticity and fail, resulting in reduced cleaning pressure on the camera and lens surfaces and incomplete cleaning.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An automatic cleaning device for industrial environment cameras includes a bracket, a cleaning fluid release mechanism, a wiping mechanism, and a pressure regulating mechanism. A camera connection portion is located in the middle of the bracket. The cleaning fluid release mechanisms are all mounted on the sides of the bracket, and the wiping mechanisms are slidably mounted on the lower part of the bracket. Each wiping mechanism has a cleaning head that can swing in a fan shape on the camera lens surface. The cleaning fluid release mechanism has a controllable cleaning fluid drain pipe that can guide the cleaning fluid to the cleaning head. The pressure regulating mechanism drives the wiping mechanism to slide in a direction perpendicular to the camera lens surface.

[0006] Furthermore, the wiping mechanism also includes a first housing, a main shaft, a rocker arm, a first motor, a synchronous belt, and a first power supply. The first housing is mounted on the bracket, and the main shaft is rotatably connected to the first housing. One end of the main shaft is located inside the first housing, and the other end is equipped with the rocker arm, which swings in a fan shape. The first motor drives the main shaft to rotate through the synchronous belt, and the first power supply supplies power to the first motor. The first motor, the synchronous belt, and the first power supply are all installed inside the first housing. The swaying end of the rocker arm is equipped with the cleaning head.

[0007] Furthermore, a bearing seat is installed inside the first housing, and the main shaft is rotatably connected to the first housing through the bearing seat.

[0008] Furthermore, a cleaning motor is installed at the swing end of the rocker arm, and the cleaning head is installed on the output shaft of the cleaning motor. The cleaning head is installed on the swing end of the rocker arm through the cleaning motor.

[0009] Furthermore, the cleaning fluid release mechanism also includes a second housing, a second motor, a connector, a liquid valve, a connecting pipe, and a storage tank. The second housing is mounted on the bracket. The second motor, connector, and liquid valve are all installed inside the second housing. The second motor is connected to the liquid valve through the connector and drives the liquid valve to open and close. The storage tank is mounted on the second housing. One end of the connecting pipe is connected to the storage tank, and the other end passes through the second housing and is connected to the liquid valve. The other end of the liquid valve is connected to the drain pipe.

[0010] Furthermore, the pressure regulating mechanism includes a third housing, a third motor, a second power supply, and a folding push rod assembly; the third motor and the second power supply are installed inside the third housing, and the second power supply supplies power to the third motor; the output end of the motor extends out of the third housing and is connected to one end of the folding push rod assembly, and the other end of the folding push rod assembly is connected to the wiping mechanism; the third motor rotates and drives the wiping mechanism to slide through the folding push rod assembly.

[0011] Furthermore, the folding push rod assembly includes a first folding rod, a second folding rod, and a step pin. One end of the first folding rod and one end of the second folding rod are hinged together by the step pin. The other end of the first folding rod is fixedly connected to the output end of the third motor, and the other end of the second folding rod is hinged to the wiping mechanism.

[0012] Furthermore, it also includes a controller, which is connected to the cleaning fluid release mechanism, the wiping mechanism, and the pressure regulating mechanism. The controller is equipped with a main control circuit that loads the cleaning program. The cleaning program controls the cleaning fluid release mechanism to release the cleaning fluid onto the cleaning head, and then controls the pressure regulating mechanism to push the wiping mechanism to slide, so that the cleaning head presses against and cleans the lens surface of the camera. After that, it controls the cleaning head to reset without obstructing the lens surface of the camera.

[0013] Furthermore, the controller also includes a timing module, a remote control module, and a sensing extension module. The controller starts the cleaning program at regular intervals through the timing module. The remote control module is used to connect to a remote terminal. The remote terminal calls the cleaning program or modifies the timing settings of the timing module through the remote control module. The sensing extension module is used to connect external sensors. The controller detects the environment around the camera through the sensing extension module.

[0014] Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows:

[0015] 1. In use, this invention releases cleaning liquid onto the cleaning head by controlling the cleaning liquid release mechanism, then controls the pressure regulating mechanism to push the wiping mechanism to slide, causing the cleaning head to press against and clean the camera lens surface. Afterwards, the cleaning head is controlled to return to its original position without obstructing the camera lens surface. By incorporating a pressure mechanism, the cleaning pressure of the cleaning head can be adjusted, improving the cleaning effect. Since the pressure of the cleaning head is adjusted by the pressure regulating mechanism, which generates cleaning pressure by causing the wiping mechanism and the cleaning head to slide close to the camera lens surface, there is no problem of cleaning failure due to aging of elastic components. This solves the technical problem of traditional camera cleaning wipers easily losing elasticity and failing, resulting in reduced cleaning pressure and incomplete cleaning of the camera and lens surface.

[0016] 2. This invention incorporates a cleaning motor. During cleaning, the cleaning motor rotates, driving the cleaning head to rotate. Combined with the fan-shaped oscillation of the cleaning head, this forms a compound cleaning motion, which lengthens the trajectory of the cleaning head on the camera lens surface within the same time frame, thereby increasing the cleaning efficiency of the cleaning head.

[0017] 3. This invention, by incorporating a controller equipped with a timing module, a remote control module, and a sensing extension module, enables multi-mode cleaning settings, including timed cleaning and remote manual intervention cleaning. Furthermore, the sensing extension module connects to sensors to detect the environment surrounding the camera and modifies the cleaning program according to different environments, thus meeting the needs of cleaning camera lenses in industrial environments.

The control principle and control technology are all existing technologies, specifically the control of the start, stop, and rotation angle of multiple motors.

[0034] In use, the cleaning fluid is released onto the cleaning head 31 by controlling the cleaning fluid release mechanism 2. Then, the pressure regulating mechanism 4 pushes the wiping mechanism 3 to slide, causing the cleaning head 31 to press against and clean the lens surface of the camera 6. Afterward, the cleaning head 31 is reset without obstructing the lens surface of the camera 6. The pressure mechanism allows adjustment of the cleaning pressure of the cleaning head 31, improving the cleaning effect. Since the pressure of the cleaning head 31 is adjusted by the pressure regulating mechanism 4, which generates cleaning pressure by causing the wiping mechanism 3 and the cleaning head 31 to slide close to the lens surface of the camera 6, there is no problem of cleaning failure due to aging of elastic components. The controller 5 is equipped with a timing module 52, a remote control module 53, and a sensing expansion module 54, enabling multi-mode cleaning settings. These include timed cleaning and remote manual intervention cleaning.
