[0002] A high-altitude surveillance camera is a type of security camera installed at a high location on a building. Over time, dust, mud, and other contaminants can easily accumulate on the external lens, affecting the camera's clarity. Because high-altitude surveillance cameras are located at great heights, manual cleaning is troublesome and poses certain risks. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a dustproof structure for a high-altitude observation camera, which effectively solves the issues in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A dustproof structure for a high-altitude observation camera includes:

[0006] Mounting plates, the two mounting plates are respectively fixedly installed on both sides of the camera;

[0007] The mounting tube is slidably mounted on each of the mounting plates;

[0008] A film replacement roll is rotatably installed inside the mounting tube. The same dustproof film is wound on the film replacement roll, and the dustproof film covers the front end of the camera.

[0009] A first driving component is fixedly installed on the mounting tube, and the output end of the first driving component is connected to the film changing roll.

[0010] A dustproof rubber ring is provided at the front of the camera, and the dustproof film is attached to the dustproof rubber ring;

[0011] A reset spring is installed between the mounting tube and the mounting plate.

[0012] Optionally, the mounting plate is fixedly connected to a second driving component, and the output end of the second driving component is fixedly connected to a cam, the cam abutting against the mounting tube.

[0013] Optionally, a film receiving plate is slidably mounted near the mounting tube, and an exit spring is provided between the film receiving plate and the mounting tube. The cam includes two flanges that abut against the mounting tube and the film receiving plate, respectively.

[0014] Optionally, a rubber roller is rotatably mounted on one end of the film-coating plate near the dust-proof film, and the dust-proof film is attached to the rubber roller.

[0015] Optionally, a first toothed disc is fixedly installed on the film roll away from the first driving member, and a second toothed disc is rotatably installed on the mounting tube. The second toothed disc is slidably installed on the mounting tube, and a torsion spring is provided between the mounting tube and the second toothed disc. The first toothed disc meshes with the second toothed disc.

[0016] Optionally, the mounting tube is fitted with a mounting post, and the torsion spring and the second gear disc are sleeved on the mounting post.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1 and Figure 2 This utility model discloses a dustproof structure for a high-altitude observation camera, comprising a mounting plate 1, two mounting plates 1 respectively fixedly mounted on both sides of the camera, a mounting tube 2 slidably mounted on the mounting plate 1, a film replacement roll 3 rotatably mounted inside the mounting tube 2, the same dustproof film 31 wound on the two film replacement rolls 3, the dustproof film 31 between the two film replacement rolls 3 covering the front end of the camera, a first driving component 41 fixedly mounted inside one of the mounting tubes 2, the output end of the first driving component 41 connected to the film replacement roll 3, a dustproof rubber ring 32 fixedly provided at the front end of the camera, the dustproof film 31 adhering to the dustproof rubber ring 32, and a return spring 51 provided between the mounting plate 1 and the mounting tube 2.

[0027] Specifically, by setting mounting tubes 2 and film replacement rolls 3 on both sides of the camera lens, the dustproof film 31 covers the camera lens portion, and the dustproof rubber ring 32 forms a seal between the dustproof film 31 and the camera lens portion. The return spring 51 provides tension to the mounting tubes 2, causing the dustproof film 31 to adhere to the dustproof rubber ring 32. When the dustproof film 31 is covered with dust, the first driving component 41 rotates the film replacement roll 3 to retract the dust-covered portion and replace it with a new dustproof film 31.

[0028] In this way, by setting up the dustproof film 31 and the dustproof rubber ring 32, and with the pulling force of the reset spring 51, the dustproof film 31 and the dustproof rubber ring 32 form a seal for the camera lens. The contaminated dustproof film 31 can be switched by the film replacement roll 3, reducing the trouble of manual wiping and thus reducing the danger of high-altitude operation.

[0029] In some feasible configurations, mounting plate 1 is rectangular and is mounted to both sides of the camera by bolts or adhesive. C-shaped slide rails are fixedly mounted on both sides of mounting plate 1. An auxiliary plate is slidably mounted on the side of mounting plate 1 away from the camera, and both sides of the auxiliary plate are slidably inserted into the C-shaped slide rails. Mounting tube 2 is fixedly mounted on the auxiliary plate. A reset spring 51 is fixedly mounted on the side of the auxiliary plate away from the camera lens, and the other end of the reset spring 51 is fixedly mounted on mounting plate 1.

[0030] The mounting tube 2 includes a round tube with a through slit on its side to allow the dustproof membrane 31 to enter and exit. The first end of the round tube is a closed end, and the second end is threaded or plugged into a cap. A drive motor, i.e., the first drive component 41, is fixedly installed inside the cap. A rotating column is fixedly installed at the output end of the first drive component 41 and plugged into the closed end.

[0031] The dustproof film 31 is a transparent plastic film, the dustproof rubber ring 32 is a rubber sealing ring, and the film replacement roll 3 is cylindrical. The dustproof film 31 is wound around the film replacement roll 3, and the film replacement roll 3 is connected to the rotating column key.

[0032] As a specific embodiment of the dustproof structure of a high-altitude observation camera provided in the application, the mounting plate 1 is fixedly connected to a second driving member 42, and the output end of the second driving member 42 is fixedly connected to a cam 421, which abuts against the mounting tube 2.

[0033] Overall, by setting cam 421, cam 421 can push the mounting tube 2 to slide. When the dustproof film 31 is switched, the cam 421 pushes to reduce the tension of the return spring 51, which facilitates the switching of the dustproof film 31.

[0034] Furthermore, a film receiving plate 43 is slidably mounted near the mounting tube 2, and an exit spring 432 is provided between the film receiving plate 43 and the mounting tube 2. The cam 421 includes two flanges that abut against the mounting tube 2 and the film receiving plate 43 respectively.

[0035] It should be understood that by setting the membrane plate 43, while the installation tube 2 moves, the membrane plate 43 pushes the dustproof membrane 31 away from the dustproof rubber ring 32, further reducing friction and facilitating the switching of the dustproof membrane 31.

[0036] Furthermore, a rubber roller 431 is rotatably mounted on one end of the film receiving plate 43 near the dustproof film 31, and the dustproof film 31 is attached to the rubber roller 431.

[0037] It should be understood that by setting the rubber roller 431, the friction between the dustproof film 31 and the film receiving plate 43 is reduced, thereby reducing the possibility of damage to the dustproof film 31.

[0038] In some feasible embodiments, the second driving component 42 is a drive motor, and the cam 421 is provided with two layers. The two layers of cam 421 are provided with different flanges according to the corresponding positions and moving distances of the film receiving plate 43 and the mounting plate 1. Two rectangular sliding grooves are provided on the mounting plate 1. Two rectangular strips are fixedly installed on one side of the film receiving plate 43. The rectangular strips are slidably installed in the sliding grooves. A C-shaped strip is bonded and fixed to the upper end of the sliding groove to form a constraint on the film receiving plate 43. The end of the rectangular strip near the cam 421 is connected by a connecting plate. The connecting plate is fixedly connected to the exit spring 432 and abuts against the cam 421.

[0039] As another specific embodiment of the dustproof structure for a high-altitude observation camera provided in the application, please refer to Figure 1 and Figure 3 A first toothed disc 61 is fixedly installed on the film changing roll 3, which is far away from the first driving component 41. A second toothed disc 62 is rotatably installed on the mounting tube 2. The second toothed disc 62 is slidably installed on the mounting tube 2. A torsion spring 63 is provided between the mounting tube 2 and the second toothed disc 62. The first toothed disc 61 meshes with the second toothed disc 62.

[0040] It should be understood that by setting the first toothed disc 61 and the second toothed disc 62, when the film roll 3 rotates, the second toothed disc 62 restricts the first toothed disc 61, and the torsion spring 63 provides rotational tension, which facilitates the sealing of the dustproof film 31 and the dustproof rubber ring 32.

[0041] Furthermore, the mounting tube 2 is equipped with a mounting post 64, and the torsion spring 63 and the second gear plate 62 are sleeved on the mounting post 64.

[0042] It should be understood that by setting the mounting post 64, the torsion spring 63 and the second gear plate 62 can be torsionally slid.

[0043] In some feasible methods, the cap of the installation tube 2 is fixedly mounted on the installation post 64. The first toothed disc 61, the second toothed disc 62, and the torsion spring 63 are sleeved on the installation post 64. The two ends of the torsion spring 63 are fixed to the cap and the second toothed disc 62, respectively. The film changing roll 3 is rotatably sleeved on the installation post 64. The first toothed disc 61 and the film changing roll 3 are inserted and fixedly connected. When the film changing roll 3 rotates, it drives the first toothed disc 61 to rotate, which in turn causes the torsion spring 63 to twist through the second toothed disc 62, generating a pulling force on the dust-proof film 31. The first toothed disc 61 and the second toothed disc 62 mesh. During the rotation of the second toothed disc 62, it slides along the installation post 64. During the switching of the dust-proof film 31, if the rotation stroke of the first toothed disc 61 is too large, the second toothed disc 62 disengages from the first toothed disc 61, resets under the drive of the torsion spring 63, and meshes with the first toothed disc 61 again.

[0044] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
