Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] The utility model provides a camera protection device for dusty environment, such as Figure 1-4 As shown, the camera protection device for dusty environment includes a protection box 1, a camera 2 arranged in the protection box 1, a box cover 11 hingedly arranged at the top opening position of the protection box 1, and a transparent glass window 12 embedded in one side of the protection box 1, and the lens end of the camera 2 faces the transparent glass window 12; the protection device also includes a cleaning structure 3 arranged on the side of the protection box 1 corresponding to the transparent glass window 12; the cleaning structure 3 includes a transmission plate 31 hingedly connected to the protection box 1 at a position below the transparent glass window 12, a cleaning brush 32 arranged at one end of the transmission plate 31 and in contact with the transparent glass window 12, and a driving mechanism 33 arranged on the protection box 1 for driving the transmission plate 31 to rotate.

[0025] When in use, the camera 2 is placed in the protective box 1 with the lens placed at one end with the transparent glass window 12. When the transparent glass window 12 needs to be cleaned, the driving mechanism 33 drives the transmission plate 31 to rotate, thereby driving the cleaning brush 32 to rotate to clean the transparent glass window 12.

[0026] Specifically, one end of the cleaning brush 32 is slidably connected to the transmission plate 31 , and the cleaning structure 3 further includes a transmission mechanism 34 disposed on the transmission plate 31 for driving the cleaning brush 32 to move along the length direction of the transmission plate 31 .

[0027] When the driving mechanism 33 drives the cleaning brush 32 to rotate to clean the transparent glass window 12, the transmission mechanism 34 drives the cleaning brush 32 to move along the length direction of the transmission plate 31, so that the cleaning brush 32 reciprocates along the length direction of the transmission plate 31 while rotating to clean the transparent glass window 12, so that the cleaning brush 32 has a better cleaning effect on the transparent glass window 12.

[0028] More specifically, the driving mechanism 33 includes a cam 331 rotating on the protective box 1, a first connecting rod 332 whose two ends are respectively hinged to the cam 331 and one end of the transmission plate 31 away from the cleaning brush 32, and a servo motor 333 fixed on the protective box 1 for driving the cam 331 to rotate.

[0029] The cam 331 installed on the output shaft of the servo motor 333 is driven to rotate by the servo motor 333, and the first connecting rod 332 whose two ends are respectively hinged to the cam 331 and the transmission plate 31 is driven to move, so that the transmission plate 31 swings around the position where it is hinged to the protective box 1, and drives the cleaning brush 32 to clean the transparent glass window 12.

[0030] More specifically, the transmission mechanism 34 includes an arcuate tooth plate 341 fixedly arranged on the inner side of the protection box 1 corresponding to the transmission plate 31, a gear 342 rotatably mounted on the transmission plate 31 and meshing with the arcuate tooth plate 341, a second connecting rod 343 arranged on a side of the transmission plate 31 away from the gear 342 and fixedly connected to the gear 342, and a third connecting rod 344 whose two ends are respectively hinged to one end of the second connecting rod 343 away from the gear 342 and one end of the cleaning brush 32 close to the transmission plate 31.

[0031] When the transmission plate 31 swings, the gear 342 rotatably mounted on the transmission plate 31 engages with the arc-shaped toothed plate 341 fixedly mounted on the protective box 1 and rotates on one side of the transmission plate 31, so that the gear 342 rotates while the transmission plate 31 swings, driving the second connecting rod 343 fixedly connected to the gear 342 to rotate, and driving the third connecting rod 344 to move, so that the cleaning brush 32 reciprocates along the length direction of the transmission plate 31 while rotating.

[0032] Furthermore, in order to allow ventilation in the protection box 1 to dissipate heat for the camera 2 , the protection device further includes a ventilation structure 4 fixedly mounted on the top of the protection box 1 .

[0033] Furthermore, an air inlet 13 is provided on the side wall of the protective box 1, and an air outlet 14 is provided on the top of the protective box 1; the ventilation structure 4 includes a protective cover 41 fixedly arranged on the protective box 1 at a position corresponding to the outer side of the air outlet 14, a cooling fan 42 fixedly arranged inside the protective cover 41, and a filter 43 fixedly arranged at one end of the protective cover 41 away from the air outlet 14 and at the inlet end of the protective box 1 corresponding to the air inlet 13.

[0034] By starting the cooling fan 42 installed in the protective cover 41, the wind is filtered by the filter 43 and enters the protective box 1 from the air inlet 13 and is then discharged from the air outlet 14. The filter 43 is set on the protective cover 41 to prevent dust from entering the protective box 1 through the air outlet 14, so that the air in the protective box 1 can circulate and dissipate heat for the camera 2.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
