Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, specifically a monitoring device with a dustproof structure. Background Technology

[0002] Surveillance devices are key equipment in security systems and intelligent management, and are widely used in complex environments such as construction sites, factories, mines, and roads. In these places, dust and particulate matter in the air can easily adhere to the lens surface of the surveillance device, leading to a decrease in image quality or even causing the surveillance function to fail.

[0003] A search revealed that patent CN220817355U discloses a building monitoring device with a dustproof structure. By activating the motor on the left end of the outer surface of the limiting seat, the motor output drives the rotating shaft to rotate. The rotating shaft, in turn, drives the pull rope to rotate. As the pull rope gradually loosens, the rotating plate rotates downwards due to gravity until it fits against the front end of the outer surface of the monitoring body. At this point, the motor on the front end of the outer surface of the rotating plate is activated, causing the motor output to drive the adjusting plate to rotate. The limiting post rotates synchronously under the drive of the adjusting plate, and drives the cleaning plate to rotate, thereby using the bristles to clean the camera lens.

[0004] However, this solution has two significant drawbacks: First, its core dustproof function is a passive cleaning method, only activating after the lens has become contaminated. Before the rotating plate opens for cleaning, the lens remains directly exposed to the environment, failing to effectively prevent initial dust adhesion, resulting in insufficient timeliness and proactive protection. Second, the rotating plate relies primarily on gravity for its descent and rotation, lacking an effective locking or pressure mechanism when in contact with the monitoring unit. This leads to wobbling or gaps between the rotating plate and the unit during cleaning, preventing the soft brush from maintaining stable and tight contact with the lens surface, directly weakening the cleaning force and reducing cleaning efficiency. Therefore, we propose a monitoring device with a dustproof structure. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a monitoring device with a dustproof structure, comprising: a monitoring body, a flipping mechanism fixed to the top of the monitoring body, the flipping mechanism including a U-shaped seat fixed to the center position of the top of the monitoring body by bolts, a hydraulic rod rotatably connected to the inner side of the U-shaped seat, a connecting block fixed to the piston end of the hydraulic rod, a first rotating shaft rotatably connected to the center hole of the connecting block, connecting rods rotatably connected to both ends of the first rotating shaft, and a second rotating shaft fixed to the front ends of the two sets of connecting rods.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-4 This utility model provides the following technical solution: A monitoring device with a dustproof structure, comprising: a monitoring body 1, a flipping mechanism 5 fixed to the top of the monitoring body 1, the flipping mechanism 5 including a U-shaped seat 51 fixed to the center position of the top of the monitoring body 1 by bolts, a hydraulic rod 52 rotatably connected to the inner side of the U-shaped seat 51, a connecting block 53 fixed to the piston end of the hydraulic rod 52, a first rotating shaft 54 ​​rotatably connected to the center hole of the connecting block 53, connecting rods 55 rotatably connected to both ends of the first rotating shaft 54, a second rotating shaft 57 jointly fixed to the front ends of the two sets of connecting rods 55, and the two ends of the second rotating shaft 57... A mounting block 56 is rotatably connected, and the bottom end of the mounting block 56 is fixed to the top edge of the monitoring body 1. A rotating plate 6 is fixed to the shaft of the second rotating shaft 57. A duct 7 is connected to the top center of the rotating plate 6. An axial flow fan 8 is fixed to the center of the duct 7. A running groove 10 is opened at the bottom end of the rotating plate 6. The left and right inner walls of the running groove 10 are rotatably connected to parallel lead screws 11 and limit posts 13 through bearings. An installation strip 14 is connected to the shaft of the lead screw 11 and the limit post 13. A soft brush 15 is fixed to the bottom end of the installation strip 14. A motor 12 is fixed to the outside of the rotating plate 6 at one end of the lead screw 11.

[0025] To achieve flexible installation of the monitoring device and basic protection of the lens: the angle of the mounting plate 3 can be adjusted by the rotating column 2 to adapt to different installation scenarios. At the same time, the glass baffle 4 is used to isolate the lens from external dust and avoid direct contamination of the lens. In this embodiment, as a preferred technical solution of this utility model, the rotating column 2 is rotatably connected to the top edge of the monitoring body 1, the top of the rotating column 2 is fixed with the mounting plate 3, and the front end of the camera lens of the monitoring body 1 is fixed with the glass baffle 4.

[0026] To ensure the stable support and reliable linkage of the flipping mechanism 5: the mounting block 56 is fixed with bolts to ensure its firm connection with the monitoring body 1. At the same time, the second rotating shaft 57 is used to realize the rotational cooperation between the connecting rod 55 and the mounting block 56, providing a stable rotation fulcrum for the flipping of the rotating plate 6. In this embodiment, as a preferred technical solution of this utility model, the rear half of the bottom end of the mounting block 56 is fixed to the monitoring body 1 with bolts, and the mounting block 56 is rotatably connected to the connecting rod 55 through the second rotating shaft 57.

[0027] To ensure smooth airflow transmission of the axial fan 8: the air duct 7 is connected to the space below the rotating plate 6 through the through hole. Combined with the straight-through air duct 7 design, the airflow resistance is reduced, ensuring that the airflow generated by the axial fan 8 can be efficiently blown onto the glass baffle 4, improving the dustproof and cleaning effect. In this embodiment, as a preferred technical solution of the present invention, the top center of the rotating plate 6 is provided with a through hole connected to the air duct 7, and the air duct 7 is a straight-through pipe with openings at both ends.

[0028] To achieve a flexible fit between the rotating plate 6 and the glass baffle 4: silicone pads 16 are used to buffer the impact force when the rotating plate 6 falls, preventing damage to the glass baffle 4 due to hard contact. At the same time, the elastic properties of silicone are used to fill the gaps in the fit, ensuring that the relative positions of the rotating plate 6 and the glass baffle 4 are fixed, providing stable conditions for subsequent cleaning. In this embodiment, as a preferred technical solution of the present invention, silicone pads 16 are fixed at the four corners of the bottom end of the rotating plate 6, and the silicone pads 16 correspond to the four corners of the glass baffle 4.

[0029] To drive the soft brush 15 to perform stable linear reciprocating motion: the rotational motion of the motor 12 is converted into the linear motion of the mounting strip 14 through the threaded engagement of the lead screw 11 and the mounting strip 14. At the same time, the guiding effect of the limiting post 13 and the running groove 10 is used to prevent the mounting strip 14 from deviating, ensuring that the soft brush 15 cleans the glass baffle 4 evenly. In this embodiment, as a preferred technical solution of the present invention, the lead screw 11 and the mounting strip 14 are threadedly connected, the limiting post 13 and the mounting strip 14 are slidably connected, and the mounting strip 14 and the running groove 10 are slidably connected.

[0030] To ensure the rotating plate 6 has a precise rotation trajectory and cleans without any blind spots: with the second rotating shaft 57 as the rotation center, the rotating plate 6 can accurately cover the area of ​​the glass baffle 4. At the same time, through the design of the soft brush 15 fitting with the glass baffle 4, it is ensured that the brush bristles can fully contact the glass surface during cleaning to avoid missing stains. In this embodiment, as a preferred technical solution of this utility model, the rear end of the rotating plate 6 rotates along the axis of the second rotating shaft 57, the position of the rotating plate 6 corresponds to the glass baffle 4, and the soft brush 15 fits into the glass baffle 4.

[0031] In this embodiment, the axial flow fan is a known technology that has been widely used in daily life. Its core is that when the impeller driven by the motor rotates at high speed, the blades will push the air to flow continuously in a direction parallel to the impeller axis, thereby generating directional wind force from the inlet to the outlet. In this process, the air flow path is basically parallel to the central axis of the fan. Its main feature is that it can provide a large air volume and provide a purging airflow for a specific area.

[0032] In summary, with the help of the above-described technical solution of this utility model,

[0033] Working principle: The operator fixes the monitoring body 1 to the target position using the mounting plate 3. The front end of the camera lens of the monitoring body 1 is equipped with a glass baffle 4, which forms a physical isolation between the lens and the external environment.

[0034] Active anti-adhesion: When the device is in routine monitoring mode, the control hydraulic rod 52 retracts, driving the first rotating shaft 54 ​​to move backward via the connecting block 53, causing the connecting rod 55 to rotate downward and backward along the central axis of the second rotating shaft 57. Since the connecting rod 55 is fixedly connected to the second rotating shaft 57, and the second rotating shaft 57 is fixedly connected to the rotating plate 6, the rear end of the rotating plate 6 is flipped upward 90° along the second rotating shaft 57, and is in an unobstructed state. At this time, the axial flow fan 8 in the air duct 7 is activated, and the airflow is blown downward through the through hole at the top of the rotating plate 6, forming an airflow barrier to prevent dust and particulate matter in the air from adhering to the surface of the glass baffle 4, thus achieving active dust prevention. At the same time, the soft brush 15 is located on the side of the bottom end of the rotating plate 6 to avoid obstructing the airflow and ensure the dust blowing range and efficiency.

[0035] Enhanced Cleaning: For environments with high dust concentrations, the piston of hydraulic rod 52 can be extended to move the first rotating shaft 54 ​​forward, causing the connecting rod 55 to rotate forward and upward along the central axis of the second rotating shaft 57. This drives the rotating plate 6 to rotate downward by 90° until the silicone pads 16 at the four corners of the bottom of the rotating plate 6 are tightly fitted with the glass baffle 4. The silicone pads 16 not only buffer the impact of the rotating plate 6 falling, protecting the glass baffle 4 from damage, but also ensure a stable fit between the rotating plate 6 and the glass baffle 4 through the driving force of the hydraulic rod 52. At this time, the air outlet of the axial flow fan 8 faces the glass baffle 4 directly, and the fine dust that has initially adhered is removed by blowing a strong airflow at close range.

[0036] Mechanical cleaning: When a thick layer of dust or stubborn stains appears on the surface of the glass baffle 4, the motor 12 is started to drive the lead screw 11 to rotate. Since the lead screw 11 is threadedly connected to the mounting strip 14, and the limiting post 13 provides guidance and constraint to the mounting strip 14, the mounting strip 14 moves linearly back and forth along the running groove 10, driving the soft brush 15 at its bottom to evenly clean the surface of the glass baffle 4. The soft brush 15 is ensured to fit tightly against the glass baffle 4 by the stable pressure of the rotating plate 6, ensuring thorough cleaning without blind spots and effectively removing stubborn stains. The motor model is 60 / 68KTYZ, and the axial flow fan model is JYF-60-14. These models are for reference only and should meet the operational requirements.

[0037] Finally, it should be noted that, in this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," "fixing," "screw connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
