A kind of device that cleans camera lens
Technical field
A kind of device that cleans camera lens of the utility model belongs to camera lens dust guard technical field.
Background technology
Nowadays, video camera is more and more universal in people's life, and whether camera lens cleans the influence of image quality very big; So the protection to camera lens is very important, still, occasion shooting that sometimes need dust content is bigger in some air; As under the coal mine, chemical plant, cement mill etc., in these local shootings, will fall to going up a lot of dust on the camera lens; Not only influence shooting quality, and bad cleaning, bigger to the camera lens injury.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved provides a kind of camera lens dust guard, makes camera lens not contaminated in the bigger place of dust.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of device that cleans camera lens; Video camera is installed in the stationary installation; Said stationary installation comprises loam cake, sleeve and bonnet, is provided with air admission hole in a side of loam cake, is provided with exhaust duct in the termination of loam cake and sleeve.
The beneficial effect that the utility model is compared with prior art had is: the utility model exhaust duct forms an annular region; When getting into, air-flow forms one swirling eddy around annular region; Air-flow makes the dust can't be near camera lens; So just kept the cleanliness of camera lens, thereby promoted shooting quality, camera lens has also been played the effect of protection.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Fig. 1 is a kind of structural representation that cleans the device of camera lens.
Among the figure: 1 is that loam cake, 2 is that exhaust duct, 3 is that air admission hole, 4 is that glass sheet, 5 is that flexible pipe, 6 is that blower fan, 7 is that sleeve, 8 is that video camera, 9 is a bonnet.
Embodiment
This a kind of device that cleans camera lens; As shown in Figure 1; A kind of device that cleans camera lens, video camera 8 is installed in the stationary installation, and said stationary installation comprises loam cake 1, sleeve 7 and bonnet 9; Side at loam cake 1 is provided with air admission hole 3, is provided with exhaust duct 2 in the termination of loam cake 1 and sleeve 7.
Loam cake 1 and sleeve 7 are connected through screw thread, and glass sheet 4 is stuck in the sleeve 7 through video camera 8, and video camera 8 is fixed in the sleeve 7 with fixed cover; Bonnet 9 is connected with sleeve 7 usefulness screws, and blower fan 6 is connected through flexible pipe 5 with air admission hole 3, during work; Gas gets into the annular region that exhaust duct 2 forms from air admission hole 3, forms one swirling eddy, makes the camera lens front form a dustless region; Air-flow makes the dust can't be near video camera 8 camera lenses; So just kept the cleanliness of camera lens, thereby promoted shooting quality, camera lens has also been played the effect of protection.
In the practical application, air-blast device can be without blower fan 6, but delivers to the air admission hole 3 through alternate manner from other place with the air of cleaning with flexible pipe 5.
