[0035] In order to conveniently clean the lens of campus surveillance camera 3, Figure 1 , Figure 2 and Figure 5As shown, the cleaning mechanism 4 includes two fixing frames 401, and the two fixing frames 401 are respectively fixedly installed on both sides of the outer wall of one end of the mounting frame 206 away from the mounting plate 1. An adjusting screw rod 403 is arranged on the inner wall of one of the fixing frames 401, and an electric motor 404 is arranged on the top of the adjusting screw rod 403. The outer thread of the adjusting screw rod 403 is sleeved with a cleaning brush 405 for cleaning the lens of the campus surveillance camera 3. When the electric motor 404 works, the cleaning brush 405 moves up and down, so as to clean the lens surface of the campus surveillance camera 3.

[0036] In order to provide power for the horizontal adjustment of the campus surveillance camera 3, such as Figure 2 As shown, a servo motor 203 is fixedly installed at one end of the bottom of the horizontal part of the mounting plate 1. The output shaft of the servo motor 203 passes through the inner wall of the mounting plate 1 and is fixedly sleeved with a rotating gear 204. The rotating gear 204 is meshed with the movable tooth plate 202. The servo motor 203 works through the meshing action between the rotating gear 204 and the movable tooth plate 202, so that the fixed plate 201 rotates on the inner wall of the mounting plate 1, and then the horizontal position of the campus surveillance camera 3 can be adjusted.

[0037] In order to keep the campus surveillance camera 3 stable during the tilt angle adjustment process, Figure 2 and Figure 4 As shown, a movable groove 207 is opened on the inner wall of the fixed plate 201, and the inner wall of one end of the movable groove 207 is fixedly connected to the electric push rod 208, and the inner wall of the movable groove 207 is movably connected to the outer wall of the movable seat 209. The front vertical section of the mounting frame 206 is set as an L-shaped structure, and a sealing plate 211 is rotatably installed on one side of the horizontal part of the mounting frame 206 close to the outer wall of one end of the mounting plate 1. The mounting frame 206 and the sealing plate 211 can install and limit the campus surveillance camera 3, and the movable groove 207 can limit the movement of the movable seat 209, so that the campus surveillance camera 3 can remain stable during the adjustment of the tilt angle in the vertical direction.

[0038] In order to make the cleaning brush 405 able to stably clean the lens surface of the campus surveillance camera 3, as shown in FIG. Figure 2 and Figure 5As shown, the inner walls of the two opposite sides of the two fixing frames 401 are provided with mounting grooves 402, wherein the inner wall of one mounting groove 402 is rotatably connected to the adjusting screw rod 403, and the inner wall of the other mounting groove 402 is fixedly installed with a limiting rod 406, and the outer wall of the limiting rod 406 is movably connected to the inner wall of the side of the cleaning brush 405 away from the adjusting screw rod 403, and the inner walls of the two mounting grooves 402 are movably connected to the outer walls on both sides of the cleaning brush 405 respectively, and the end of the cleaning brush 405 close to the lens of the campus surveillance camera 3 is set as a sponge structure, and the mounting groove 402 and the limiting rod 406 can limit the movement of the cleaning brush 405, so that the cleaning brush 405 can stably clean the lens of the campus surveillance camera 3, and the setting of the sponge material can prevent the cleaning brush 405 from scratching the lens.

[0039] In order to provide power for the movement of the cleaning brush 405, as Figure 2 and Figure 5 As shown, the top of one of the fixing brackets 401 is fixedly connected to the electric motor 404, and the electric motor 404 is connected to the adjusting screw rod 403 through an output shaft transmission. One of the fixing brackets 401 can install and fix the electric motor 404. When the electric motor 404 works, the adjusting screw rod 403 rotates, so that the cleaning brush 405 can clean the lens surface of the campus surveillance camera 3.

[0040] When installing the campus monitoring equipment, the campus monitoring camera 3 is inserted into the mounting frame 206 so that its lens faces the end away from the mounting plate 1, and then the opening of the mounting frame 206 close to the mounting plate 1 can be closed by rotating the sealing plate 211, so that the campus monitoring camera 3 can remain stable inside the mounting frame 206, and then the mounting plate 1 is installed to a suitable position on the campus by bolts, and then during the monitoring process, the electric push rod 208 is operated by remote control, so that the movable seat 209 moves along the inner wall of the movable groove 207, and then under the traction of the traction plate 210, the mounting frame 206 is rotated around the bottom of the fixed seat 205, so that the inclination angle of the campus monitoring camera 3 can be adjusted, and at the same time, the servo motor 203 is operated by remote control, and the meshing action between the rotating gear 204 and the movable tooth plate 202 makes the fixed plate 201 on the mounting plate 1 The inner wall of the campus surveillance camera 3 can be rotated, so that the horizontal position of the campus surveillance camera 3 can be adjusted, and the shooting angle of the campus surveillance camera 3 can be conveniently adjusted as needed, which can improve the adaptability of the monitoring equipment. At the same time, when the shooting content observed by the staff through the terminal is blurred, the electric motor 404 can be operated through remote control, and the adjusting screw rod 403 can be driven to rotate, so that the cleaning brush 405 can move on its outside. At the same time, the installation groove 402 and the limiting rod 406 can limit the movement of the cleaning brush 405, so that the cleaning brush 405 can stably clean the lens surface of the campus surveillance camera 3, so as to ensure the clarity of the monitoring equipment, and thus ensure the safety of the campus. This embodiment specifically solves the problem that the campus surveillance equipment in the prior art cannot adjust the shooting angle as needed, and the lens is easily contaminated and affects the clarity.

[0041] A light entry calibration mechanism is also provided at the front end of the campus surveillance camera 3, which is located inside the lens surface and close to the lens surface. This structure is mainly used to achieve the conversion and filtering of natural light. The light entry calibration mechanism is composed of multiple reflectors, which realize the surrounding reflection of light when it enters. Figure 6As shown, the multiple reflectors are, in sequence, a light input reflector 51, a right reflector 52, a middle reflector 53, a left reflector 54, and a light output reflector 55. The incoming light passes through the light input reflector 51, the right reflector 52, the middle reflector 53, the left reflector 54, and the light output reflector 55 in sequence and then exits. The multiple reflectors ensure that the angle between the incoming light and the emitted light is less than 10°. Preferably, that is, in the initial state, the multiple reflectors ensure that the incoming light and the emitted light are basically parallel. Among them, the light input reflector 51 and the light output reflector 55 are integrally formed and symmetrically arranged. The angle α between the reflection surfaces of the light input reflector 51 and the light output reflector 55 is 140 to 160 degrees, preferably 150 degrees, and the light input reflector 51 and the light output reflector 55 are fixed on the first reflection rotation device 56 to achieve the rotation condition. Correspondingly, the right reflector 52, the middle reflector 53, and the left reflector 54 are constructed as a whole, and the right reflector 52, the middle reflector 53, and the left reflector 54 form an inverted U shape. In this embodiment, multiple reflectors are plane reflection, but in fact, concave or convex surface can also be used to achieve reflection. For example, the middle reflector 53 can be set to an upwardly arched arc surface. It is fixed on the second reflection rotating device 57 to achieve rotation adjustment. Among them, a light opening 58 for light to enter is formed between the left reflector 54 and the light-incoming reflector 51. Through this setting, the light can be better gathered, the clarity of the picture can be better, and the entry of invalid light can be effectively reduced, reducing interference.

[0042] like Figure 7 As shown, after the light incident reflector 51 and the light emitting reflector 55 are rotated counterclockwise by the first reflection rotating device 56, the angle of the incoming light changes, and the change angle here is 5 degrees.

[0043] like Figure 8 As shown, after the second reflective rotating device 57 is used to rotate the whole body consisting of the right reflector 52, the middle reflector 53, and the left reflector 54 clockwise, the angle of the incoming light also changes, and the change angle here is 2 degrees.

[0044] like Fig. 9 As shown, after the second reflection and rotation device 57 is used to rotate the whole body consisting of the right reflector 52, the middle reflector 53, and the left reflector 54 counterclockwise, the angle of the incoming light also changes, and the change angle here is 3 degrees.

[0045] Moreover, the first reflection rotating device 56 and the second reflection rotating device 57 can be used to cooperate to achieve the angle difference between the incoming light and the outgoing light. This allows for more convenient adjustments to the camera's sight, viewing angle, clarity, and the like. Of course, the rotation of the first reflection rotating device 56 and the second reflection rotating device 57 is actually very small, usually no more than 15 degrees, and the first reflection rotating device 56 and the second reflection rotating device 57 can use micro motors. In addition, for light filtering, a tiny diffuse reflection structure can be set on the right reflector 52, such as using a plurality of continuous tiny prism surfaces or arc surfaces. By setting up the diffuse reflection structure, some light can be eliminated, so that during the day, the brightness and clarity of the monitoring screen can be better. The diffuse reflection is set on the right reflector so that the light will not directly enter the camera, thereby ensuring that the light entering the camera must have undergone a complete annular reflection, thereby ensuring the quality of the light.

[0046] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
