Description

Technical Field

[0001] This utility model relates to the field of protection technology for terminal equipment of monitoring systems, and specifically to a camera protection self-cleaning device. Background Technology

[0002] Terminal equipment protection is a crucial research area in the application of monitoring systems, especially in harsh environments such as concrete production, transportation, and construction, where it faces significant challenges. These scenarios are typically filled with large amounts of dust, frequent high-pressure water washing, and cement slurry splashes, posing extremely severe environmental tests to the use of terminal equipment. As critical terminal equipment, the effective protection of surveillance cameras in extreme environments is a decisive factor in the effective and reliable application of the monitoring system. Therefore, there is an urgent need for processes and devices that can effectively protect cameras from dust corrosion, high-pressure water washing, and cement slurry splashes.

[0003] Currently, the main protective technologies for monitoring system terminal equipment include electric brush cleaning, high-pressure fluid blowing / rinsing, and ultrasonic cleaning. However, these technologies all exhibit certain limitations in specific application scenarios: While electric brush cleaning can effectively remove some attached materials, the sharp-edged cement debris generated during concrete production can easily cause continuous scratches to the camera lens during cleaning. This places high demands on the wear resistance of the lens material, and long-term use can not only lead to serious lens damage but also significantly reduce image clarity, affecting monitoring performance. High-pressure fluid blowing / rinsing relies on the availability of high-pressure water or pressurized air on-site, limiting its application scenarios. Furthermore, the application of high-pressure fluid requires cameras to have extremely high waterproof and dustproof ratings. Ultrasonic cleaning utilizes the cavitation, acceleration, and direct flow effects of ultrasound in liquids to directly or indirectly affect liquids and contaminants, dispersing, emulsifying, and peeling away the contaminants to achieve cleaning. However, its application environment is limited to liquid containers, and its operation is complex and costly.

[0004] In summary, existing protection technologies for monitoring system terminal equipment have limitations and shortcomings to varying degrees in extreme environments such as building material production scenarios, and cannot meet the needs of large-scale application and promotion. It is necessary to improve and innovate existing protection methods in order to solve the above problems. Utility Model Content

[0018] As one possible design, the aforementioned transmission assembly includes an electric push rod, a driving link, a driven link, and a guide traction rod.

[0019] There are two electric push rods, which are symmetrically installed on both sides of the housing about the camera and are connected to the active linkage to drive the active linkage to move.

[0020] The two ends of the active linkage are connected to the electric push rod and the driven linkage, respectively, to drive the driven linkage to move;

[0021] The driven link is rotatably connected to the guide traction rod, and is used to drive the guide traction rod to reciprocate.

[0022] One end of the guide traction rod is rotatably connected to the driven link, and the other end is connected to the protective eyelid and the cleaning brush respectively. It is used to drive the protective eyelid to open and close, and to drive the cleaning brush to move.

[0047] Example

[0048] This utility model provides a camera protection self-cleaning device, referring to... Figure 1-6 The system includes a connecting base 1, a housing 3, a protective cover 12, a cleaning brush 14, and a transmission assembly. The connecting base 1, installed externally, is used to rotate and connect to the housing 3, allowing the housing 3 to rotate relative to the external structure for convenient monitoring of the camera 2. The housing 3, connected to the connecting base 1, houses and protects the camera 2 internally. It is a hollow cuboid with an open end. The camera 2 is installed inside the housing 3, with its monitoring end located at the opening. The opening is detachably connected to the protective cover 12. The protective cover 12 is detachably mounted at the opening of the housing 3, preferably connected by screws or welding, forming a space with the housing 3 to protect the camera 2. The cleaning brush 14 is movably mounted inside the housing 3, contacting the camera 2 for cleaning it. The transmission assembly is connected to the protective cover 12 and the cleaning brush 14, driving the protective cover 12 to open and close, and moving the cleaning brush 14.

[0049] Preferably, the connector 1 is a universal joint connector, which facilitates the angle adjustment of the camera 2.

[0050] Preferably, camera 2 can be any model.

[0051] In some embodiments, refer to Figure 1 , Figure 5-6 The protective cover 12 includes a fixed frame 121, movable covers 122, and pressure plates 123. The fixed frame 121 is connected to the open end of the housing 3. The shape of the fixed frame 121 is the same as the cross-sectional shape of the housing 3, and it is used to form a space for protecting the camera 2 together with the housing 3. The fixed frame 121 has an opening 124 to accommodate the camera 2 and facilitate its operation. The opening 124 can be quadrilateral, hexagonal, circular, or other shapes. The opening 124 is used by the camera 2 to monitor the outside. There are two movable covers 122, which are symmetrically arranged. One end of the movable cover 122 is fixedly connected to the fixed frame 121, and the other end is connected to the transmission component. It is used to close the opening 124 when it is necessary to close the protective cover 2, thereby protecting the camera 2 and preventing external substances such as cement mortar from damaging the camera surface. The pressure plates 123 are fixedly connected to the fixed frame 121 and the open end of the housing 3 respectively. Preferably, there are at least two pressure plates, but there can also be four. They are used to fix the fixed frame 121 and the housing 3 with screws.

[0052] In some embodiments, refer to Figure 1 , Figure 5-6 The movable eyelid 122 is made of an elastic material, preferably an elastic material with excellent comprehensive properties such as high elasticity, aging resistance, and fatigue resistance. It can be natural rubber, silicone rubber, or other elastic materials.

[0053] In some embodiments, refer to Figure 2-4 The transmission assembly includes an electric push rod 4, a driving link 7, a driven link 8, and a guide traction rod 10. There are two electric push rods 4, which are symmetrically installed on both sides of the housing 3 about the camera 2 and are driven by the active link 7, preferably hinged, to facilitate the simultaneous movement of the active link 7. The two ends of the active link 7 are hinged to the electric push rod 4 and the driven link 8 respectively, to drive the driven link 8 to move. The driven link 8 is rotatably connected to the guide traction rod 10, preferably hinged, to drive the guide traction rod 10 to reciprocate. Specifically, when the electric push rod 4 is pushed out, it will drive the active link 7 out, which in turn will drive the driven link 8 upward. Due to the limited space inside the housing 3, the driven link 8 will gradually change from moving upward to moving laterally, thereby pushing out the guide traction rod 10. One end of the guide traction rod 10 is rotatably connected to the driven link 8, preferably hinged, and the other end is driven by the movable eyelid 122 of the protective eyelid 12 and the cleaning brush 14 respectively, to drive the movable eyelid 122 to open and close, and to drive the cleaning brush 14 to reciprocate.

[0054] In some embodiments, refer to Figure 2-4 There are two driven links 8. One driven link 8 is hinged to the inner wall of the housing 3, and the other driven link 8 is hinged to the guide traction rod 10. The two driven links 8 are hinged to each other, and one end of the two driven links 8 is rotatably connected to the driving link 7. This structure allows the driven link 8 to change its direction of movement when it moves upward, thereby conveniently pushing out the guide traction rod 10.

[0055] In some embodiments, refer to Figure 2-4 A driven link 8 is connected to the guide traction rod 10 via a link hinge seat 9.

[0056] In some embodiments, refer to Figure 2-4 The transmission assembly also includes guide grooves 11, of which there are two sets. The two sets of guide grooves 11 are symmetrically arranged about the opening 124. Each set includes two guide grooves 11. The two guide grooves 11 are symmetrically arranged about the camera 2. The guide grooves 11 are fixed inside the protective eyelid 12 and are used for sliding installation of the guide traction rod 10.

[0057] In some embodiments, refer to Figure 2-4 The electric push rod 4 is rotatably mounted on the inner wall of the cover 3 via the push rod hinge seat 5.

[0058] Preferably, the electric push rod 4 and the push rod hinge seat 5 are connected by a pin 6.

[0059] In some embodiments, refer to Figure 2-4 The cover 3 is detachably connected to a maintenance plate 31, which facilitates the maintenance of the internal camera 2 and other components.

[0060] In some embodiments, a sealing gasket is provided between the cover 3 and the inspection plate 31 to prevent external dust and other substances from entering the cover 3.

[0061] Typical application scenarios for this camera protection self-cleaning device are as follows:

[0062] i. Concrete Mixer Truck Unloading Quality Monitoring. At construction sites, the quality of concrete unloading from concrete mixer trucks significantly impacts the pumping process. This protective self-cleaning device is installed above the unloading chute at the rear of the concrete mixer truck and connected to the tank rotation signal. When the tank reverses to unload, the movable flap 122 automatically opens, and the camera automatically and in real-time monitors the concrete unloading process. When the tank is in other states, the movable flap 122 automatically closes, thus providing protection for the device's internal components.

[0063] ii. Security and Production Process Monitoring within Concrete Batching Plants. Concrete batching plants are characterized by high dust levels, frequent high-pressure water washing, and significant cement slurry splashing. The operating environment for monitoring terminal equipment at some workstations is extremely harsh, requiring high levels of protection for the monitoring devices. This protective self-cleaning device is installed near specific workstations within the concrete batching plant. It is connected to a push-button switch signal or a production system control signal to control the operation of the electric actuator 4, thereby controlling the opening or closing of the movable panel 122. This achieves both protection and self-cleaning functions for the monitoring device in this scenario.
