DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0022] A monitoring device for highways; comprising a base 1, a first rotating ring 4 is rotatably connected inside the base 1, a first rotating mechanism matched with the first rotating ring 4 is arranged inside the base 1, a protective cover 5 is fixedly connected to the first rotating ring 4, a cleaning brush 10 matched with the protective cover 5 is arranged on the base 1, and a first cleaning mechanism matched with the cleaning brush 10 is arranged on the base 1; a protective cover 6 matched with the protective cover 5 is fixedly connected above the protective cover 5; a fixed inner column 13 matched with the first rotating ring 4 is fixedly connected to the base 1, the fixed inner column 13 is located inside the protective cover 5, a camera 12 is arranged on the fixed inner column 13, and a first adjusting mechanism matched with the camera 12 is arranged inside the fixed inner column 13; a fixing frame 2 is fixedly connected below the base 1.

[0023] like Figure 1 , 2 As shown in Figure 3: when the staff installs the present invention, it can be installed in a suitable position through the fixing bracket 2; when the camera 12 needs to be adjusted, the angle of the camera 12 can be adjusted through the first adjusting mechanism, and when the protective cover 5 needs to be cleaned, the first cleaning mechanism operates on the side of the protective cover 5 corresponding to the cleaning brush 10 for cleaning. After the first cleaning mechanism is reset, the movement of the first rotating mechanism drives the protective cover 5 to rotate rapidly. At this time, a new side of the protective cover 5 will correspond to the cleaning brush 10, and then the above operation is repeated, thereby realizing the cleaning of the side of the protective cover 5 corresponding to the camera 12. In this process, the impact on the camera 12 can be minimized to the greatest extent; it effectively solves the problems in the prior art that the monitoring equipment lacks wide-angle adjustment, interferes with the capture during the cleaning process and affects the monitoring effect, and greatly improves the capture accuracy.

[0024] The first cleaning mechanism includes a guide rail frame 3 fixedly connected to the base 1, a first lifting stud 7 is rotatably connected between the base 1 and the guide rail frame 3, a pair of fixed guide columns 9 are fixedly connected between the base 1 and the guide rail frame 3, the fixed guide columns 9 are respectively located on both sides of the first lifting stud 7 and are symmetrically arranged, a lifting screw plate 8 is screwed on the first lifting stud 7, the fixed guide columns 9 are all slidably connected to the lifting screw plate 8, an adjusting slide column 15 is fixedly connected to the lifting screw plate 8, a cleaning connecting column 11 slidably connected to the adjusting slide column 15 is fixedly connected to the cleaning brush 10, a pair of guide blocks 14 are fixedly connected to the cleaning connecting column 11, the guide blocks 14 are respectively located on both sides of the cleaning connecting column 11 and are symmetrically arranged; a sliding groove matching the guide block 14 is provided on the guide rail frame 3.

[0025] like Figure 2 and 3 As shown: when the first lifting stud 7 rotates, under the action of the fixed guide column 9, the rotation of the first lifting stud 7 can drive the lifting screw plate 8 to be lifted and lowered. When the lifting screw plate 8 moves upward, the cleaning connecting column 11 and the cleaning brush 10 can be lifted and lowered by the adjusting slide column 15. At the same time, under the action of the guide block 14 and the slide groove, the cleaning connecting column 11 and the adjusting slide column 15 will slide relative to each other, thereby driving the cleaning brush 10 to clean the protective cover 5.

[0026] The first adjustment mechanism includes a first fixed link 16 fixed to the fixed inner column 13, the other end of the first fixed link 16 is rotatably connected to the camera 12, a second lifting stud 18 is rotatably connected in the fixed inner column 13, a first telescopic link 17 threadedly connected to the second lifting stud 18 is slidably connected to the fixed inner column 13, the other end of the first telescopic link 17 is rotatably connected to the camera 12, and at the same time, a sliding groove matching the first telescopic link 17 is provided on the camera 12, and the first telescopic link 17 can also be slidably connected to the camera 12.

[0027] like Figure 4 and 5 As shown: when the angle of the camera 12 needs to be adjusted, the second lifting stud 18 can be driven by the motor to rotate. The rotation of the second lifting stud 18 can drive the first telescopic link 17 to adjust the height. When the height of the first telescopic link 17 is adjusted, it drives the camera 12 to rotate. At the same time, the camera 12 and the first telescopic link 17 will slide relative to each other. During this process, the camera 12 and the first fixed link 16 will rotate relative to each other.

[0028] The first rotating mechanism includes a first rotating worm wheel 19 and a first rotating worm 20 which are rotatably connected in the base 1, and the first rotating worm wheel 19 and the first rotating worm 20 are meshed with each other; the first rotating worm wheel 19 is coaxially fixed to the first rotating ring 4; all surfaces of the protective cover 5 are planes; the material of the protective cover 5 is glass; the cleaning brush 10 does not contact the first rotating ring 4 in its initial position, so the cleaning brush 10 will not interfere with the protective cover 5 when the first rotating ring 4 rotates; the upper surface of the protective cover 6 is conical.

[0029] like Figure 1 and 6 As shown: the motor drives the first rotating worm 20 to rotate, and the rotation of the first rotating worm 20 can drive the first rotating ring 4 to rotate through the first rotating worm wheel 19, thereby driving the protective cover 5 and the protective cover 6 to rotate; the flat glass has a relatively small effect on the focal length and focus of the camera. In an ideal case, if the thickness of the glass is uniform and the refractive index is stable, it will basically not change the original focal length of the lens. Because when the light passes through the flat glass vertically, although a certain translation will occur, it will not change the degree of convergence of the light; the curved glass will change the effective focal length of the lens. Due to its curved shape, the position of the convergence point will change after the light is refracted by the curved glass. This may cause the object that was originally focused on by the camera to become blurred, or the focus needs to be readjusted to obtain a clear image; for example, in some surveillance cameras with curved protective covers, the focal length of the lens needs to be specially calibrated to compensate for the focal length change caused by the curved glass.

[0030] The working process of the present invention is: like Figure 1 , 3, 4 and 6: when the staff installs the present invention, it can be installed in a suitable position through the fixing frame 2; when the camera 12 needs to be adjusted, the angle of the camera 12 can be adjusted through the first adjusting mechanism, and when the angle of the camera 12 needs to be adjusted, the second lifting stud 18 can be driven by the motor to rotate, and the rotation of the second lifting stud 18 can drive the first telescopic link 17 to adjust the height, and the first telescopic link 17 drives the camera 12 to rotate when the height is adjusted. At the same time, the camera 12 and the first telescopic link 17 will slide relative to each other, and during this process, the camera 12 and the first fixed link 16 will rotate relative to each other; when the protective cover 5 needs to be cleaned, the first cleaning mechanism runs on the side of the protective cover 5 corresponding to the cleaning brush 10 to clean, and when the first lifting stud 7 rotates, under the action of the fixed guide column 9, the rotation of the first lifting stud 7 can drive the lifting screw plate 8 to be lifted and lowered. , when the lifting screw plate 8 moves upward, the cleaning connection column 11 and the cleaning brush 10 can be lifted and lowered by adjusting the slide column 15; at the same time, under the action of the guide block 14 and the slide groove, the cleaning connection column 11 and the adjusting slide column 15 will slide relative to each other, thereby driving the cleaning brush 10 to clean the protective cover 5; after the first cleaning mechanism is reset, the first rotating mechanism moves to drive the protective cover 5 to rotate rapidly, at this time, a new side of the protective cover 5 will correspond to the cleaning brush 10, and the motor drives the first rotating worm 20 to rotate, and the rotation of the first rotating worm 20 can drive the first rotating ring 4 to rotate through the first rotating worm gear 19, thereby driving the protective cover 5 and the protective cover 6 to rotate; then repeat the above operation, so as to realize the cleaning of the side of the protective cover 5 corresponding to the camera 12, and in this process, the impact on the camera 12 can be minimized; the flat glass has a relatively small effect on the focal length and focus of the camera. Ideally, if the thickness of the glass is uniform and the refractive index is stable, it will basically not change the original focal length of the lens. Because when light passes vertically through flat glass, although it will produce a certain degree of translation, it will not change the degree of convergence of light; curved glass will change the effective focal length of the lens. Due to its curved shape, the position of the convergence point will change after the light is refracted by the curved glass. This may cause the object that the camera originally focused on to become blurred, or the focus needs to be readjusted to obtain a clear image; for example, in some surveillance cameras with curved protective covers, the focal length of the lens needs to be specially calibrated to compensate for the focal length change caused by the curved glass; it effectively solves the problems in the existing technology that the monitoring equipment lacks wide-angle adjustment, the cleaning process causes interference to the capture and affects the monitoring effect, and greatly improves the capture accuracy.
