[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually illustrative only and in no way limits the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0032] As Figures 1 to 5 shown, an embodiment of the present invention provides a monitoring camera device, which includes a control box 10 and a monitoring component 20. The monitoring component 20 includes a monitoring camera 21 and a cleaning member 22. The monitoring camera 21 includes a main body portion 211 and an imaging portion 212. The main body portion 211 is connected to the control box 10, and the imaging portion 212 is rotatably provided on the main body portion 211. The cleaning member 22 is connected to the main body portion 211 and is located on one side of the imaging portion 212. Among them, the imaging portion 212 has a monitoring position and a cleaning position. When the imaging portion 212 is in the monitoring position, the cleaning member 22 is misaligned with the imaging portion 212 in the rotation direction of the imaging portion 212. When the imaging portion 212 rotates from the monitoring position to the cleaning position, the cleaning member 22 is in contact with the outer surface of the imaging portion 212.

[0033] When applying the monitoring camera device provided in this embodiment, during the use of the monitoring camera device, if dust adheres to the surface of the imaging portion 212 of the monitoring camera 21, the imaging portion 212 can be rotated from the monitoring position to the cleaning position. During this process, since the cleaning member 22 is in contact with the outer surface of the imaging portion 212, the dust adhering to the surface of the imaging portion 212 can be cleaned by the cleaning member 22, ensuring the clarity of the captured image of the monitoring camera device. Moreover, when the imaging portion 212 is in the monitoring position, the cleaning member 22 is misaligned with the imaging portion 212 in the rotation direction of the imaging portion 212, and the cleaning member 22 does not block the imaging portion 212, that is, the cleaning member 22 does not affect the normal imaging of the imaging portion 212.

[0034] As Figure 2 shown, in this embodiment, the cleaning member 22 includes a mounting frame 221 and a cleaning brush 222. The mounting frame 221 is connected to the main body portion 211, and the cleaning brush 222 is detachably provided on the mounting frame 221. When the imaging portion 212 rotates from the monitoring position to the cleaning position, the cleaning brush 222 is in contact with the outer surface of the imaging portion 212. This design enables the cleaning brush 222 to be conveniently replaced after being used for a period of time, ensuring the cleaning effect, being suitable for long-term running monitoring scenarios, and ensuring the clarity of the monitoring image.

[0035] As Figure 2As shown, in this embodiment, the cleaning member 22 further includes a plug board 223 and a positioning board 224. The cleaning brush 222 is fixedly arranged on the plug board 223. A sliding groove is provided on the mounting bracket 221, and the sliding groove penetrates through one end of the mounting bracket 221. The plug board 223 can be inserted into the mounting bracket 221 through the sliding groove. The positioning board 224 is detachably arranged on the mounting bracket 221. After the plug board 223 is inserted into the mounting bracket 221, the positioning board 224 can be in limit cooperation with the plug board 223 to prevent the plug board 223 from falling off from the sliding groove. This design not only facilitates the replacement of the cleaning brush 222, but also ensures the stability of the cleaning brush 222 during use, avoids the falling off of the cleaning brush 222 during use, and ensures the cleaning effect.

[0036] In addition, the replacement of the cleaning brush 222 has also become more convenient and can be completed without special tools, greatly improving the equipment maintenance efficiency.

[0037] As Figure 3 shown, a first screw 227 that is helically arranged with the mounting bracket 221 penetrates through the positioning board 224.

[0038] As Figure 3 shown, in this embodiment, the cleaning member 22 further includes a damping member 225 and a spring 226. Both the damping member 225 and the spring 226 are located in the sliding groove. The extending direction of the spring 226 is perpendicular to the extending direction of the sliding groove. One end of the spring 226 is connected to the inner wall of the sliding groove, and the other end of the spring 226 is connected to the damping member 225. After the plug board 223 is inserted into the mounting bracket 221, the end of the damping member 225 away from the spring 226 abuts against the side wall of the plug board 223. The damping member 225 and the spring 226 are located between the cleaning brush 222 and the mounting bracket 221. The function of the damping member 225 is to increase the damping between the cleaning brush 222 and the mounting bracket 221 and improve the assembly stability. The spring 226 is used to provide an appropriate pre-pressure to ensure that a stable cleaning force can be provided when the cleaning brush 222 contacts the imaging part 212.

[0039] During the cleaning process, when the imaging part 212 rotates to the position of the cleaning brush 222, the pre-pressure of the spring 226 makes the cleaning brush 222 gently fit on the surface of the imaging part 212, avoiding scratches on the lens surface caused by excessive cleaning force. Such a design ensures that when the cleaning brush 222 is cleaning, it can effectively remove dust and stains on the lens surface without causing any damage to the lens.

[0040] As Figure 2As shown, in this embodiment, the monitoring component 20 further includes a screw 30. The upper end of the mounting bracket 221 is provided with a connecting plate 2211, and a slot is provided on the main body portion 211. The connecting plate 2211 is inserted into the slot, and the screw 30 passes through the connecting plate 2211 and is connected to the main body portion 211. With the above structure, the cleaning member 22 is set to a structure that can be removed from the monitoring camera 21 as a whole, facilitating the overall replacement of the cleaning member 22.

[0041] As Figure 1 shown, in this embodiment, the monitoring camera device further includes a protective cover 40 and a lifting component 50. The protective cover 40 is connected to the control box 10, the protective cover 40 is located above the monitoring component 20, the lifting component 50 is connected to the control box 10, and the main body portion 211 is liftably arranged on the control box 10 through the lifting component 50. The lifting component 50 has a raised position and a lowered position. When the lifting component 50 moves from the lowered position to the raised position, the distance between the monitoring component 20 and the protective cover 40 decreases. With the above structure, in rainy or snowy weather, the monitoring component 20 is controlled to rise and approach below the protective cover 40 to protect the monitoring component 20 and prevent the monitoring camera 21 from being covered by rain or snow.

[0042] Among them, the lifting component 50 includes a guiding frame 51, a lifting block 52, and a driving member 53. The guiding frame 51 is fixedly connected to the control box 10, the lifting block 52 is liftably arranged on the guiding frame 51, the main body portion 211 is connected to the lifting block 52, the driving member 53 is arranged on the guiding frame 51, and the driving member 53 is drivingly connected to the lifting block 52 to drive the lifting block 52 to move relative to the guiding frame 51. With the structure of the cooperation between the guiding frame 51 and the lifting block 52, the smoothness of the lifting of the monitoring component 20 can be improved.

[0043] Specifically, the lifting component 50 further includes a threaded shaft 54 and a cross bar 55. The threaded shaft 54 is rotatably arranged on the guiding frame 51. The lifting component 50 includes two lifting blocks 52, and one of the lifting blocks 52 is sleeved on the threaded shaft 54 and is threadedly connected to the threaded shaft 54. The driving member 53 includes a servo motor, and the servo motor is drivingly connected to the threaded shaft 54. The two lifting blocks 52 are respectively connected to both ends of the cross bar 55, and the main body portion 211 is connected to the cross bar 55. The monitoring component 20 further includes a connecting housing 60, and the connecting housing 60 is sleeved on the cross bar 55, and the main body portion 211 is connected to the connecting housing 60. With the above structure, through the precise design of the lifting component 50, the lifting action of the monitoring component 20 is ensured to be stable and accurate.

[0044] It should be noted that the driving member 53 (servo motor) provides precise driving force and can achieve the lifting of the monitoring component 20 with extremely low error according to the control signal, ensuring the accuracy when adjusting the monitoring height. The cooperation between the threaded shaft 54 and the lifting block 52 is the key to the smooth lifting action. The rotational motion of the threaded shaft 54 is converted into the linear motion of the lifting block 52. Due to the high precision of the thread, this conversion process is very smooth and will not generate sudden jumps or vibrations, thus avoiding interference with the picture during the lifting of the monitoring component. The guide frame 51 guides the linear motion of the lifting block 52, and the cross bar 55 connects the lifting block 52 and the connecting housing 60 to ensure the stability of the monitoring camera 21 during lifting. The combined action of these structural designs enables the monitoring component 20 to maintain the stability and clarity of the monitoring picture when adjusting the height.

[0045] Moreover, although the damping member 225 and the spring 226 are mainly used for adjusting the contact between the cleaning brush 222 of the cleaning member 22 and the imaging unit 212, they also contribute to indirectly improving the smoothness of the monitoring component 20 during movement by absorbing vibrations and adjusting the contact force of the cleaning brush 222 throughout the lifting process of the monitoring component 20.

[0046] In addition, this design utilizes the self-locking property of the thread and the combined use of the threaded shaft and the servo motor, enabling the monitoring component 20 to remain stable at any height and being applicable to various occasions that require long-term monitoring at specific heights.

[0047] As Figure 4 shown, the guide frame 51 includes a top plate and two side plates. The upper ends of the two side plates are respectively connected to both ends of the top plate. The lifting block 52 is vertically movable relative to the side plates, and the protective cover 40 is arranged below the top plate.

[0048] Specifically, a second screw 56 inserted into the top plate penetrates through the interior of the protective cover 40. A nut 57 that fits against the lower surface of the top plate is spirally arranged on the outer side of the second screw 56. The protective cover 40 can be quickly assembled to the bottom end of the top plate through the second screw 56 and the nut 57.

[0049] Among them, a guide post extending vertically is also provided on the guide frame 51, and the connecting housing 60 is sleeved on the guide post.

[0050] As Figure 1 shown, in this embodiment, the monitoring and imaging device further includes a bracket 70. The upper end of the bracket 70 is connected to the control box 10, and the upper end of the guide frame 51 is connected to the lower end of the bracket 70. The setting of the bracket 70 provides a stable support for the entire monitoring and imaging device and is applicable to various monitoring occasions that require high stability.

[0051] Among them, the monitoring and imaging device provided in this embodiment further includes a power supply, a controller, a switch, etc.

[0052] To facilitate the understanding of the monitoring camera device provided in this embodiment, the working principle and process of the monitoring camera device will be described below:

[0053] The staff installs the control box 10 and the monitoring component 20 above the wall or pole body in the monitoring area. Through the connected wires, the staff can view the images detected by the monitoring camera 21 in the monitoring component 20 using a display screen. When the monitoring camera 21 becomes blurred, the lower half (imaging unit 212) of the monitoring camera 21 can be controlled to rotate. When the imaging unit 212 rotates to the position of the cleaning brush 222, the floating dust on the surface of the imaging unit 212 can be scraped off to maintain a clear shooting field of view of the imaging unit 212.

[0054] The staff can regularly pull out the cleaning brush 222 and the plug board 223 from the inside of the mounting bracket 221 for replacement. After the replacement is completed, the plug board 223 is inserted into the inside of the mounting bracket 221, and the positioning plate 224 is installed at the bottom of the mounting bracket 221 using the first screw 227 for sealing. Moreover, the screw 30 can also be removed for overall disassembly and replacement.

[0055] When using the monitoring component 20 in rainy or snowy weather, the protective cover 40 can be inserted into the inside of the guide frame 51 through the second screw 56 and tightened and positioned using the nut 57. In rainy or snowy weather, the servo motor at the top end of the guide frame 51 of the lifting component 50 can be controlled to work, driving the threaded shaft 54 at the end of the main shaft to rotate, controlling the outer lifting block 52 to rise, driving the connection housing 60 and the monitoring component 20 to rise through the cross bar 55, and moving under the protective cover 40 to protect the monitoring component 20.

[0056] The monitoring camera device provided by this embodiment has the following beneficial effects:

[0057] (1) Through the cleaning brush structure in the monitoring component, a replaceable cleaning brush structure is provided on one side of the monitoring camera. During the operation of the camera for recording the construction site, when the recording becomes blurred, the lower half of the camera can be controlled to rotate. After the camera passes through the cleaning brush, the floating dust on the surface can be cleaned, ensuring that the monitoring field of view is maintained during the process of monitoring the construction site.

[0058] (2) Through the lifting component and the protective cover structure above, in rainy or snowy weather, the monitoring component can be controlled to rise and approach under the protective cover to protect the monitoring component, avoiding the situation where the monitoring camera is covered by rain or snow.
