[0018] 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.

[0019] Please see Figure 1-5This utility model provides a video surveillance device that is easy to adjust at multiple angles, including: a mounting base 1, a vertical plate 2 fixedly inserted into the bottom outer wall of the mounting base 1, and a sliding groove 3 opened on one side outer wall of the vertical plate 2. It also includes: a lifting assembly 4 rotatably mounted on the top outer wall of the vertical plate 2, a camera 5 rotatably mounted on one side outer wall of the vertical plate 2, a driving assembly 6 mounted on the bottom inner wall of the mounting base 1, an air supply assembly 7 mounted on one side outer wall of the vertical plate 2, a fan cover 8 mounted on the top inner wall of the camera 5, a first connecting pipe 9 connected to the top inner wall of the fan cover 8, a second connecting pipe 10 connected to the bottom inner wall of the air supply assembly 7, a telescopic pipe 11 connected between the first connecting pipe 9 and the second connecting pipe 10, and one end of the lifting assembly 4 rotatably connected to the top of the camera 5.

[0020] It should be noted here that: Angle adjustment: The drive component 6 drives the lifting component 4 to move, and through mechanical transmission, it pushes the camera 5 to rotate around the rotation axis on one side of the upright plate 2, thereby adjusting the shooting angle and range;

[0021] Dust removal: The drive component 6 simultaneously drives the air supply component 7 to generate airflow. The airflow is delivered to the wind cover 8 through the second connecting pipe 10, the telescopic pipe 11, and the first connecting pipe 9, and finally blown towards the lens of the camera 5, solving the problem of difficult dust removal at high places.

[0022] The telescopic tube 11 can flexibly extend and retract according to the angle of the camera 5 to ensure stable airflow transmission; the slide 3 provides guidance for the movement of related components to ensure smooth operation of the structure.

[0023] In a preferred embodiment, the lifting assembly 4 includes a threaded rod 401, a lifting block 402 screwed onto the threaded rod 401, a driven bevel gear 403 mounted on the top of the threaded rod 401, and a traction rod 404 rotatably mounted on one side of the outer wall of the lifting block 402.

[0024] It should be noted here that when the driven bevel gear 403 is driven to rotate by the drive assembly 6, it will synchronously drive the threaded rod 401 to rotate.

[0025] When the threaded rod 401 rotates, the lifting block 402, which is screwed to it, moves up and down along the threaded rod 401 (constrained by the thread).

[0026] The up-and-down movement of the lifting block 402 is transmitted to the camera 5 through the traction rod 404, which pulls or pushes the camera 5 to rotate around the rotation axis of the upright plate 2, ultimately realizing the adjustment of the shooting angle (tilt angle) and solving the problem of "adjusting the shooting range".

[0027] In a preferred embodiment, the drive assembly 6 includes a motor 601, a drive bevel gear 602 mounted on the outer wall of the output shaft of the motor 601, a turntable 603 mounted on one end of the output shaft of the motor 601, and a connecting rod 604 rotatably mounted on the eccentric position of the turntable 603.

[0028] It should be noted here that after the motor 601 starts, the output shaft drives the drive bevel gear 602 and the turntable 603 to rotate synchronously;

[0029] The active bevel gear 602 provides the power for angle adjustment of the lifting assembly 4 (transmitted through gear meshing);

[0030] The eccentric position of the turntable 603 is connected to the connecting rod 604. When it rotates, the circular motion is converted into the reciprocating push-pull motion of the connecting rod 604, which provides power to the air supply assembly 7.

[0031] By using a "single motor to drive dual functions", the structure is simplified and collaborative operation is ensured.

[0032] In a preferred embodiment, the air supply assembly 7 includes a cylinder 701, a piston 702 slidably connected to the inner wall of the cylinder 701, a first check valve 703 installed on the inner wall of one side of the cylinder 701, and a second check valve 704 installed on the inner wall of the bottom of the cylinder 701.

[0033] It should be noted here that the piston 702 slides back and forth along the inner wall of the cylinder 701 under the action of the connecting rod 604;

[0034] When piston 702 moves upward, the air pressure inside cylinder 701 decreases, the first check valve 703 (intake valve) opens, and outside air enters cylinder 701;

[0035] When piston 702 moves downward, the air pressure inside cylinder 701 increases, the second check valve 704 (exhaust valve) opens, and air is discharged through the second connecting pipe 10.

[0036] The exhaust airflow passes through the pipe and is ultimately blown by the fan cover 8 to the lens of the camera 5 to clean the dust; two check valves ensure that the airflow flows in one direction to prevent air leakage.

[0037] In a preferred embodiment, the bottom of the connecting rod 604 is rotatably connected to the top of the piston 702.

[0038] It should be noted here that when the turntable 603 rotates, the connecting rod 604 at the eccentric position performs a circular motion, which is converted into the linear reciprocating motion of the piston 702 through the "rotational connection" (to avoid motion interference caused by rigid connection).

[0039] In a preferred embodiment, the driving bevel gear 602 meshes with the driven bevel gear 403.

[0040] It should be noted here that the rotational motion of the output shaft of motor 601 is transmitted to the driven bevel gear 403 via the driving bevel gear 602 (due to gear meshing);

[0041] Driven bevel gear 403 is fixedly connected to threaded rod 401, thereby driving threaded rod 401 to rotate, providing power for angle adjustment of lifting assembly 4.

[0042] Working principle:

[0043] The equipment is fixed by mounting base 1, with upright plate 2 serving as the supporting frame. The core is powered by drive component 6, simultaneously achieving two main functions: "angle adjustment" and "dust cleaning." The specific process is as follows:

[0044] Angle adjustment path: Drive component 6 → Lifting component 4 → Camera 5 angle change;

[0045] Dust cleaning path: Drive component 6 → Air supply component 7 → Airflow duct 10-11-9 → Fan cover 8 → Camera 5 lens;

[0046] The telescopic tube 11 can flexibly extend and retract with the angle of the camera 5 to ensure airflow transmission; the slide 3 provides guidance for the movement of the components to ensure structural stability.

[0047] II. Working principle of angle adjustment function (core components: 6→4→5)

[0048] Drive component 6 provides power:

[0049] After the motor 601 starts, the output shaft drives the drive bevel gear 602 and the turntable 603 to rotate synchronously;

[0050] The driving bevel gear 602 transmits rotational power to the lifting assembly by meshing with the driven bevel gear 403 of the lifting assembly 4.

[0051] Lifting component 4 transmission angle:

[0052] The driven bevel gear 403 rotates, causing the threaded rod 401 to rotate synchronously.

[0053] The rotation of the threaded rod 401 causes the threaded lifting block 402 to move up and down along the threaded rod;

[0054] The lifting block 402 pushes and pulls the camera 5 through the traction rod 404, causing the camera 5 to rotate around the rotation axis of the upright plate 2, ultimately achieving the adjustment of the shooting angle (tilt angle).

[0055] III. Working principle of dust cleaning function (core components: 6→7→8)

[0056] Drive component 6 synchronously drives the air supply:

[0057] When the output shaft of motor 601 drives the turntable (603) to rotate, the connecting rod 604 at the eccentric position of the turntable 603 performs reciprocating push-pull motion (circular motion is converted into linear motion).

[0058] Air supply component 7 generates airflow:

[0059] The connecting rod 604 drives the piston 702 to slide back and forth in the cylinder 701: when the piston 702 moves upward, the air pressure in the cylinder 701 decreases, the first check valve 703 opens, and external air enters the cylinder.

[0060] When piston 702 moves downward, the air pressure inside cylinder 701 increases, the second check valve 704 opens, and compressed air is discharged through the second connecting pipe 10.

[0061] Airflow reaches the lens:

[0062] The exhaust airflow is sequentially transported to the fan cover 8 through the telescopic pipe 11 and the first connecting pipe 9, and finally blown in a direction by the fan cover 8 toward the lens of the camera 5 to clean the dust.

[0063] In summary, the device, through the "single motor 601 driving dual system", not only achieves multi-angle adjustment of camera 5, but also simultaneously solves the problem of dust cleaning of the lens at high positions. Through the synergy of mechanical transmission and pneumatic transmission, the various components achieve the core requirements proposed in the background technology.

[0064] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
