Abstract
The invention discloses a video camera dust-proof device, mainly comprising a fan shell, a large round hole, a small round hole, an annular air chamber, an air gap, protecting glass, set screw holes and a compressed air inlet joint, wherein the fan shell is cylindrical, the large round hole is arranged at the left side of the fan shell, the small round hole is arranged at the right side of the large round hole, a chamfer is arranged at the right side of the small round hole, the periphery of the small round hole is provided with the annular air chamber, the protecting glass is arranged between the annular air chamber and the large round hole, the air gap is arranged between the protecting glass and the small round hole, two to four set screw holes are uniformly distributed corresponding to the periphery of the large round hole, and the compressed air inlet joint is arranged above the fan shell corresponding to the annular air chamber. In the invention, a good air curtain protective screen is formed in front of the protecting glass to isolate and block dust pollution; and the dust-proof device is simple to design and is easy to produce.
Description
Technical field
The present invention relates to a kind of dust guard, relate in particular to and guarantee the not contaminated dustproof fan housing of video camera camera lens in a kind of high dust atmosphere.
Background technology
At present, the method that solves the preceding contamination by dust problem of video camera camera lens mostly is regularly artificial and cleans, and automatic, the semi-automatic hydroblasting mode of employing is also arranged, the recent mode that mechanical wiper also occurred installing additional to video camera.With upper type all be the video camera camera lens by the situation of contamination by dust under, remove to dispose the dirt that attaches, make the visual field recover clear, bright again, this all is not that truly active is dustproof, should belong to the maintenance measure of video camera camera lens after contaminated.Coal-face under coal mine adopts artificial mode of cleaning because the place is narrow, dust pollution is serious, and not only labour intensity is big, and cleaning untimelyly also can increase potential safety hazard; Adopt the mode of hydroblasting, the easier dirt of being stained with, water wave own, the water stain image definition that also influences; Adopt the mode of mechanical wiper, cleaning effect is unsatisfactory, also need clean and change often and hang brush, and can grind lens element because of dust granule, causes sharpness to descend.
Summary of the invention
In order to overcome the deficiencies in the prior art, solve the contaminated problem of video camera camera lens, the invention provides a kind of video camera dust guard.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of video camera dust guard, mainly by the fan housing housing, big hole, small sircle hole, ring-shaped air chamber, the gas gap, cover plate, set screw hole and pressurized air inlet suction port are formed, its fan housing housing is a cylindrical shape, the fan housing housing left side is provided with big hole, the big hole right side is provided with small sircle hole, the small sircle hole right side is provided with chamfering, the small sircle hole outer periphery is equipped with ring-shaped air chamber, be provided with cover plate in the middle of ring-shaped air chamber and the big hole, be provided with the gas gap in the middle of cover plate and the small sircle hole, peripheral uniform two to four set screw hole that are provided with of corresponding big hole, the corresponding ring-shaped air chamber in fan housing housing top is provided with the pressurized air inlet suction port.
The technical scheme that the present invention solves its technical matters also can be:
A kind of video camera dust guard, its pressurized air inlet suction port is a body, and the pressurized air inlet suction port communicates with ring-shaped air chamber, gas gap and small sircle hole air, and described gas gap is the 1-2 millimeter.
The invention has the beneficial effects as follows:
1, before cover plate, forms good air curtain (curtain) barrier, isolate and the blocking-up dust pollution;
2, simplicity of design is easy to manufacture.
