Technical Field

[0001] This utility model relates to the field of camera lens cleaning technology, and in particular to an outdoor surveillance camera that facilitates the cleaning of lens dust. Background Technology

[0002] Outdoor surveillance cameras are used for 24 / 7 monitoring and are typically installed outdoors. They provide real-time video surveillance and image recording to ensure public safety or the protection of private property. Because outdoor environments are prone to dust accumulation, water damage, or contamination, camera lenses need to be easy to clean to ensure clear images and prevent dust or water droplets from affecting image quality.

[0003] As shown in the reference case "An Environmental Monitoring Device Easy to Clean" announcement number "CN221743651U", in this utility model, when cleaning the monitoring device, the user only needs to crank the hand crank to make the shell rise and fall with the lifting platform to clean the surface of the shell. There is no need to climb to a high place with a ladder to carry out the cleaning work, making the operation safe and convenient. While the aforementioned application allows the camera to be raised and lowered by cranking a handle, making it easier for staff to clean, the camera lens may contain impurities such as dust, dry pollen, and willow catkins. These impurities have low adhesion but can still affect the lens. Raising the camera frequently may increase the workload of staff and also cause the camera to be idle for too long. Utility Model Content

[0004] Therefore, it is necessary to provide an outdoor surveillance camera that facilitates lens dust cleaning, addressing the issue that cleaning cameras can only be achieved by using a lifting camera.

[0005] An outdoor surveillance camera that facilitates lens dust cleaning includes: a column and a camera body, wherein a lifting mechanism is provided between the camera body and the column; The cleaning mechanism includes a protective box disposed on the surface of a column. Inside the protective box, there is a fixed plate and a sliding plate slidably connected to the fixed plate. The surface of the sliding plate is provided with a cleaning brush and an air jet nozzle.

[0006] In one embodiment, the protective case has a door on the side near the camera body, and an electric push rod is fixedly connected to the top of the protective case, with the drive end of the electric push rod fixedly connected to the door.

[0007] In one embodiment, the jet nozzle is fixedly connected to the surface of the skateboard and tilted upwards, and an air pump is fixedly connected to the surface of the skateboard, the air pump being connected to the jet nozzle.

[0008] In one embodiment, a drive motor is fixedly connected to the surface of the skateboard, and the drive end of the drive motor is fixedly connected to the cleaning brush.

[0009] In one embodiment, the inner wall of the fixing plate is provided with a threaded rod, one end of which is rotatably connected to the inner wall of the fixing plate and the other end of which passes through the fixing plate.

[0010] In one embodiment, a servo motor is fixedly connected to one side of the fixing plate, and the drive end of the servo motor is fixedly connected to one end of the threaded rod that passes through the fixing plate.

[0011] In one embodiment, the surface of the threaded rod is provided with a connecting block, the connecting block is "G" shaped, one end of the connecting block is slidably connected to the inner wall of the fixing plate, and the other end of the connecting block extends through the bottom end of the fixing plate and is bent and slidably connected to the surface of the fixing plate. The sliding plate is fixedly connected to the connecting block.

[0012] In one embodiment, a control box is fixedly connected to the surface of the column, and the control box is electrically connected to the camera body, the electric push rod, the drive motor and the servo motor.

[0013] Beneficial effects 1.

[0022] The following is combined with Figures 1-5 This invention describes an outdoor surveillance camera that facilitates lens dust cleaning.

[0023] In one embodiment, an outdoor surveillance camera that facilitates lens dust cleaning includes: a column 100 and a camera body 300, wherein a lifting mechanism 200 is provided between the camera body 300 and the column 100. The cleaning mechanism 400 includes a protective box 410 disposed on the surface of the column 100. The interior of the protective box 410 is provided with a fixing plate 420 and a sliding plate 430 slidably connected to the fixing plate 420. The surface of the sliding plate 430 is provided with a cleaning brush 450 and an air nozzle 440.

[0024] In this device, the working principle of the surveillance camera mainly relies on several basic processes such as image acquisition, signal transmission, and data storage. The camera captures images or video signals of the surrounding environment through its built-in image sensor. The signal is converted into a digital signal by a processing chip, and after encoding and compression, it is transmitted to the control center or storage device via wired or wireless network. The camera is usually also equipped with infrared functionality to ensure clear monitoring in low-light environments. The lifting mechanism 200 consists of a lead screw installed inside the column 100, a connecting rod connecting the camera body 300 to the surface of the lead screw, and a motor that drives the lead screw to rotate. When deep cleaning of the lens is required, the camera body 300 needs to be completely lowered through the lifting mechanism 200 for cleaning. When controlling the camera's lifting and lowering, the control box 110 controls the motor to drive the lead screw to rotate. The rotation of the lead screw drives the connecting rod to move, thereby raising and lowering the camera body 300. The surface of the lead screw is provided with an elastic threaded sleeve to protect the lead screw from the influence of impurities.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, the protective case 410 has a door on the side near the camera body 300. An electric push rod 411 is fixedly connected to the top of the protective case 410, and the drive end of the electric push rod 411 is fixedly connected to the door. An air nozzle 440 is fixedly connected to the surface of the slide plate 430 and tilted upwards. An air pump 441 is fixedly connected to the surface of the slide plate 430 and is connected to the air nozzle 440. A drive motor 451 is fixedly connected to the surface of the slide plate 430, and the drive end of the drive motor 451 is fixedly connected to the cleaning brush 450. A threaded rod 422 is provided on the inner wall of the fixing plate 420. One end is rotatably connected to the inner wall of the fixed plate 420, while the other end extends through the fixed plate 420. A servo motor 421 is fixedly connected to one side of the fixed plate 420. The drive end of the servo motor 421 is fixedly connected to one end of the threaded rod 422 that extends through the fixed plate 420. A connecting block 423 is provided on the surface of the threaded rod 422. The connecting block 423 is "G" shaped. One end of the connecting block 423 is slidably connected to the inner wall of the fixed plate 420. The other end of the connecting block 423 extends through the bottom end of the fixed plate 420, bends, and is slidably connected to the surface of the fixed plate 420. The sliding plate 430 is fixedly connected to the connecting block 423.

[0026] In this embodiment, the camera body 300 is positioned below the protective box 410 during monitoring operations. It only rises to the position of the protective box 410 when the lens of the camera body 300 needs cleaning. Therefore, the protective box 410 does not obstruct the monitoring range of the camera body 300. The door of the protective box 410 is slidably connected to one side of the protective box 410, and an inverted "L"-shaped block is provided at the top of the door. The electric push rod 411 opens and closes the door by pushing the "L"-shaped block. When the door is closed, the "L"-shaped block, in conjunction with the outer shell of the electric push rod 411, keeps the body of the electric push rod 411 in a sealed state, reducing the impact of the environment on the electric push rod 411. The cleaning brush material... The material is nylon. Because the threaded rod 422 is set on the inner wall of the fixed plate 420, and the sliding groove required for the connecting block 423 to move on the fixed plate 420 is opened from the bottom of the fixed plate 420, the contact between external impurities and the threaded rod 422 can be greatly reduced. At the same time, because the cleaning mechanism 400 of this device only opens the protective box 410 when cleaning the camera body 300 and closes it after cleaning, the time that the cleaning mechanism 400 is exposed to the air is greatly reduced, thereby protecting the threaded rod 422 and reducing the impact of atmospheric impurities on the threaded rod 422. At the same time, the surface of the threaded rod 422 is provided with an elastic threaded sleeve, which further protects the threaded rod 422. It should be noted that the cleaning mechanism 400 in this device is located on the surface of the column 100 and is set independently of the camera. Therefore, the cleaning mechanism 400 will not change the internal components of the camera body 300, and will not affect the normal installation and operation of the camera body 300. At the same time, since the cleaning mechanism 400 only works when cleaning the camera, and the camera body 300 should be in a power-off state during this process and only cleans the lens of the camera body 300, it will not affect the subsequent monitoring operation of the camera body 300. In summary, the cleaning mechanism 400 of this device will not affect the normal operation of the camera body 300.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a control box 110 is fixedly connected to the surface of the column 100. The control box 110 is electrically connected to the camera body 300, the electric push rod 411, the drive motor 451, and the servo motor 421.

[0028] All electronic components in this device are electrically connected to the control box 110, and the drive electronic components in this device are all controlled to start and stop through the control box 110. Operators can remotely operate the control box 110 through the control system to control this device.

[0029] Working principle: When some impurities with low adhesion but which have a certain impact on the camera lens appear on the lens, the operator can drive the electric push rod 411 through the control box 110 to raise the door of the protective box 410, and then drive the lifting mechanism 200 to raise the camera body 300 slightly above the cleaning mechanism 400. Then, the servo motor 421 is started, which drives the threaded rod 422 to rotate. The rotation of the threaded rod 422 drives the connecting block 423 to move and simultaneously drives the slide plate 430 to move closer to the camera body 300. Depending on the impurities on the lens, the air nozzle 440 or the cleaning brush is selected to clean the lens. If you choose to clean the lens using the air nozzle 440, point the air nozzle 440 at the lens and then start the air pump 441. The air pump 441 will spray air obliquely upward from the air nozzle 440 onto the lens of the camera body 300 to clean the impurities on the lens surface. If you choose to clean the lens using the cleaning brush, point the cleaning brush at the lens and then start the drive motor 451. The drive motor 451 will drive the cleaning brush to rotate and clean the impurities on the lens surface. After cleaning, the servo motor 421 is driven to rotate in the reverse direction by the control cabinet, so that the slide plate 430 is reset. Then, the electric push rod 411 is driven to reset the door of the protective box 410. Finally, the lifting mechanism 200 is controlled to reset the camera body 300.

[0030] It should be noted that the lifting mechanism 200, servo motor 421, drive motor 451, electric push rod 411, air pump 441, camera body 300, and threaded rod 422 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the lifting mechanism 200, servo motor 421, drive motor 451, electric push rod 411, air pump 441, and camera body 300 can be powered by built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
