Description

Technical Field

[0001] This utility model relates to a video surveillance device, and more particularly to a video surveillance device with a detachable multi-angle bracket for use in the field of surveillance equipment. Background Technology

[0002] Video surveillance is an important component of security systems. Traditional surveillance systems include front-end cameras, transmission cables, and video surveillance platforms. Cameras can be divided into network digital cameras and analog cameras, which can be used to acquire video image signals. It is a comprehensive system with strong security capabilities. Video surveillance is widely used in many situations because of its intuitiveness, accuracy, timeliness, and rich information content.

[0003] When video surveillance equipment is used outdoors, the surface of the camera may become dusty, which can affect the clarity of the camera. Existing patents generally use a cleaning brush to clean the camera. For example, Chinese Patent Publication No. CN222531772U discloses a video surveillance device that uses a micro drive motor to rotate a rotating plate, which in turn rotates the cleaning brush to remove dust from the camera lens.

[0004] When cleaning the camera surface with a cleaning brush, the brush makes hard contact with the camera lens, and hard particles may be trapped inside. During the wiping process, the brush may scratch the camera lens surface and damage the coating. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the cleaning brush makes hard contact with the camera lens, and hard particles may be trapped inside, which may scratch the surface of the camera lens during the wiping process and cause damage to the coating.

[0006] To address the aforementioned problems, this utility model provides a video surveillance device with a detachable multi-angle bracket, including a mounting plate. An adjusting bracket is fixedly connected to the lower end of the mounting plate, and an adjusting plate is fixedly connected to the lower end of the adjusting bracket. Two limiting grooves are chiseled on the right end of the adjusting plate, and two limiting strips are provided within the limiting grooves. A positioning plate is fixedly connected to the lower ends of the two left limiting strips, and a pressure strip is fixedly connected to the right ends of the two right limiting strips. The pressure strip is fixedly connected to the adjusting plate by bolts. A camera is fixedly connected to the lower end of the positioning plate, and two mounting brackets are fixedly connected to both the upper and lower ends of the camera. The mounting brackets include components located on the camera. Two mounting plates are used. The left mounting plate is fixedly connected to the camera, and the left end of the right mounting plate is fixedly connected to a locking strip, which is inserted into the left mounting plate and fixedly connected to the left mounting plate by bolts. Each mounting plate has a mounting block rotatably connected to one end, and the corresponding ends of the two mounting blocks are chiseled with slots. An installation roller is provided between the two mounting plates, and the left and right ends of the installation roller are respectively inserted into a slot. A micro motor is fixedly connected to the end of one of the mounting plates on one of the mounting frames. The output end of the micro motor is fixedly connected to an installation block. A wiping cloth is covered on both mounting rollers, and the surface of the wiping cloth is chiseled with multiple monitoring windows.

[0007] In the aforementioned video surveillance device with a detachable multi-angle bracket, this application replaces the traditional rotating cleaning brush with a unidirectional rolling wiping method using a wiping cloth, which helps reduce the repeated adhesion of contaminants to the lens surface, and through the setting of the monitoring window, it is less likely to affect the normal use of the lens.

[0008] As a further supplement to this application, U-shaped limiting frames are fixedly connected to both the upper and lower ends of the camera. The limiting frames are located in front of the mounting bracket and outside the wiping cloth.

[0009] As a further supplement to this application, the two mounting brackets are symmetrically distributed, the longitudinal section of the two slots is a regular hexagon, and the left and right ends of the mounting roller are fully matched with the slots.

[0010] As a further addition to this application, the wiping cloth is attached to the front end of the camera, and the monitoring window is located in front of the camera lens.

[0011] As a further supplement to this application, the adjustment bracket includes an electric turntable installed at the lower end of the mounting plate. An adjustment seat is fixedly connected to the lower end of the electric turntable. An electric rotating rod is installed inside the adjustment seat. A positioning block is fixedly sleeved on the outside of the electric rotating rod. The lower end of the positioning block is fixedly connected to the upper end of the adjustment plate.

[0012] As a further supplement to this application, a dustproof baffle is provided outside the mounting bracket without the micro motor. The dustproof baffle is fixedly connected to the card plate on the left side, and the end of the dustproof baffle away from the card plate is in contact with a limit bracket.

[0013] As a further supplement to this application, an L-shaped mounting rod is fixedly connected to one of the mounting plates of the mounting bracket with the micro motor, and a pressure sensor is fixedly connected to the end of the mounting rod near the wiping cloth.

[0014] In summary, in practical applications, covering the camera lens with a wiping cloth effectively prevents external dust and impurities from directly adhering to the camera surface. When the wiping cloth becomes dusty and affects the camera's operation, the operator can activate a micro motor to drive an installation roller, which pulls the wiping cloth to roll and refresh it. This moves the monitoring window on the wiping cloth to the front of the camera, and the rolling of the wiping cloth cleans the camera surface, helping to reduce the repeated adhesion of contaminants to the lens surface.

Detailed Implementation

[0027] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0028] First implementation method:

[0029] Figures 1-4 The following describes a video surveillance device with a detachable multi-angle bracket, comprising a mounting plate 1. An adjusting bracket 2 is fixedly connected to the lower end of the mounting plate 1. An adjusting plate 3 is fixedly connected to the lower end of the adjusting bracket 2. Two limiting grooves 4 are chiseled on the right end of the adjusting plate 3. Two limiting strips 5 are provided within the limiting grooves 4. A positioning plate 6 is fixedly connected to the lower ends of the two left limiting strips 5. A pressure strip 7 is fixedly connected to the right ends of the two right limiting strips 5. The pressure strip 7 is fixedly connected to the adjusting plate 3 by bolts. A camera 8 is fixedly connected to the lower end of the positioning plate 6. When it is necessary to disassemble / assemble the camera 8 and the adjusting bracket 2, the bolts between the pressure strip 7 and the adjusting plate 3 can be unscrewed. Then, the pressure strip 7 can be pulled outwards to disengage the two right limiting strips 5 from the limiting grooves 4. Then, the positioning plate 6 can be pushed to disengage the two left limiting strips 5 from the limiting grooves 4, allowing the camera 8 to be removed.

[0030] Figure 3 and Figure 4 The diagram shows that the adjustment bracket 2 includes an electric turntable 21 installed at the lower end of the mounting plate 1. Those skilled in the art can select a suitable model of electric turntable 21 according to actual needs, such as Y200RA. An adjustment seat 22 is fixedly connected to the lower end of the electric turntable 21. An electric rotating rod 23 is installed inside the adjustment seat 22. Those skilled in the art can select a suitable model of electric rotating rod 23 according to actual needs, such as JCW-0001. A positioning block 24 is fixedly sleeved on the outside of the electric rotating rod 23. The lower end of the positioning block 24 is fixedly connected to the upper end of the adjustment plate 3. The electric turntable 21 can drive the adjustment seat 22 to rotate, causing the camera 8 located below the adjustment seat 22 to rotate. Then, the electric rotating rod 23 drives the positioning block 24 to rotate, thereby changing the angle of the camera 8, which facilitates the camera 8 to monitor different positions.

[0031] Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown: Two mounting brackets 9 are fixedly connected to both the upper and lower ends of the camera 8. The two mounting brackets 9 are symmetrically distributed. The mounting bracket 9 includes two clamping plates 91 located on the camera 8. The left clamping plate 91 is fixedly connected to the camera 8. The left end of the right clamping plate 91 is fixedly connected to a clamping strip 92. The clamping strip 92 is inserted into the left clamping plate 91, and the clamping strip 92 is fixedly connected to the left clamping plate 91 by bolts. By removing the bolts, the right clamping plate 91 can be moved to the right, and then the clamping strip 92 can be pulled to the right to increase the gap between the two clamping plates 91, thereby facilitating the installation and removal of the mounting roller 95.

[0032] Two mounting plates 91 are rotatably connected to mounting blocks 93 at their corresponding ends. The corresponding ends of the two mounting blocks 93 are grooved 94. An mounting roller 95 is provided between the two mounting plates 91. The left and right ends of the mounting roller 95 are respectively inserted into a groove 94. The longitudinal section of the two grooves 94 is a regular hexagon. The left and right ends of the mounting roller 95 are completely matched with the grooves 94. A micro motor 96 is fixedly connected to the end of one of the mounting plates 91 on one of the mounting frames 9. Those skilled in the art can select a suitable model of micro motor 96 according to actual needs, such as QDD-520. The output end of the micro motor 96 is fixedly connected to a mounting block 93. The left and right ends of the mounting roller 95 are regular hexagonal rods that can be inserted into the grooves 94. After the micro motor 96 is started, the micro motor 96 can drive a mounting block 93 to rotate, thereby driving the mounting roller 95 to rotate and retract the wiping cloth 10.

[0033] Two mounting rollers 95 are fitted together with a wiping cloth 10. The surface of the wiping cloth 10 has multiple monitoring windows 14, located in front of the lens of the camera 18. The wiping cloth 10 is in contact with the front end of the camera 8. When the camera 8 is not being cleaned, the monitoring windows 14 do not obstruct its normal use. When cleaning is required, as the mounting rollers 95 rotate, the wiping cloth 10 moves, and the wiping cloth 10 between the two monitoring windows 14 comes into contact with the lens of the camera 8, thereby wiping away dust from the surface of the camera 8 until the first... Two monitoring windows 14 are located in front of the camera 8. Multiple monitoring windows 14 are equidistantly arranged on the wiping cloth 10, so that the monitoring window 14 can be replaced by rotating the mounting roller 95 a fixed number of times each time. U-shaped limit frames 11 are fixedly connected to both the upper and lower ends of the camera 8. The limit frames 11 are located in front of the mounting frame 9 and outside the wiping cloth 10. The limit frames 11 are used to limit the lateral movement and shaking of the wiping cloth 10, especially in windy environments, so that the wiping cloth 10 is finally flat and attached to the front of the lens, effectively improving the stability of the wiping cloth 10 during use.

[0034] When using this video surveillance equipment, firstly, insert the mounting roller 95 carrying a brand new wiping cloth 10 into the mounting frame 9 without the integrated micro motor 96. Then, insert an empty mounting roller 95 into the drive end mounting frame 9 with the micro motor 96. Manually pull the free end of the wiping cloth 10 so that it passes smoothly through the upper and lower limit frames 11, finally adhering firmly to the surface of the empty mounting roller 95. At this time, one of the monitoring windows 14 is located in front of the lens of the camera 8, without affecting the normal use of the camera 8. When the lens of the camera 8 is contaminated with dust, oil, or other impurities, affecting the image quality, the operator can remotely or locally start the micro motor 96. After the micro motor 96 starts, it will drive the empty mounting roller 95 on its mounting frame 9. The mounting roller 95 rotates to perform a winding operation. The tension generated by this winding action will simultaneously pull the mounting roller 95 on the other side, which carries a brand new wiping cloth 10, to rotate, thereby realizing the overall movement of the wiping cloth 10. During the movement, the unopened part between the two monitoring windows 14 slides and adheres to the lens of the camera 8, thereby wiping away the dust on the lens of the camera 8 and cleaning it. As the mounting roller 95 rotates, the contaminated wiping cloth 10 is continuously wound up to the outer end of the previously empty mounting roller 95 and stored until the other monitoring window 14 moves in front of the lens of the camera 8. Compared with the unwiped state, this operation can restore a certain degree of field of view clarity to the camera 8 and effectively improve the image shooting quality.

[0035] Second implementation method:

[0036] This embodiment adds a dustproof baffle 12 and a pressure sensor 13 to the first embodiment, while the rest remains the same as the first embodiment.

[0037] Figure 9 and Figure 10 As shown: A dustproof baffle 12 is provided on the outside of the mounting bracket 9 without the micro motor 96. The dustproof baffle 12 is fixedly connected to the left-side clamping plate 91, and the end of the dustproof baffle 12 away from the clamping plate 91 is in contact with a limiting frame 11. An L-shaped mounting rod is fixedly connected to one of the clamping plates 91 of the mounting bracket 9 with the micro motor 96. A pressure sensor 13 is fixedly connected to the end of the mounting rod near the wiping cloth 10. The mounting rod is located at the edge of the clamping plate 91 so that when the wiping cloth 10 rotates, the pressure sensor 13 will not enter the monitoring window 14. Those skilled in the art can select a suitable model of pressure sensor 13 according to actual needs, such as SQB.

[0038] When using the wiping cloth 10 to protect the camera 8 from dust, after replacing the mounting roller 95 with a brand new one containing the wiping cloth 10, the dust baffle 12 can effectively cover the section between the mounting roller 95 and the limit frame 11, which can significantly reduce the possibility of the exposed wiping cloth 10 getting dusty and wet by rain, and improve the cleanliness of the spare wiping cloth 10.

[0039] When the micro motor 96 starts and drives the empty mounting roller 95 to wind up the contaminated wiping cloth 10, the diameter of the wiping cloth 10 will gradually increase. As the winding proceeds, the distance between the outer surface of the wiping cloth 10 and the pressure sensor 13 will continuously decrease. When the wiping cloth 10 is wound to a certain thickness, its outer surface will eventually contact the pressure sensor 13 and generate a detectable pressure signal. This signal triggers a system alarm, automatically reminding the staff that the wiping cloth 10 is about to run out and that a new mounting roller 95 needs to be prepared for replacement, thus facilitating the staff's use.

[0040] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
