Abstract
The invention includes airtight protective shell, flux adjustable balking ring type airflow screen generator, and clean compressed air source. The balking ring type airflow screen generator is setup in front of camera lens sealed in the protective shell. Distance between the airflow screen and the taking lens is adjustable. Comparing with prior art, the invention solves issues of blurred image taken by camera lens, inconvenient for maintaining lens, difficult for monitoring images in harsh environment etc.
Description
One. technical field
The present invention relates to the dustproof dirt-proof protector of a kind of pick-up lens, especially a kind of air-flow formation screen that utilizes is isolated the lens protecting apparatus that the pick-up lens surface was arrived or contacted in the gentle body drop of various dust materials.
Two. background technology
At present, in industries such as many important industry, fire-fighting, traffic, it is very general to utilize pick-up lens to monitor to its whole process.Yet, especially people, thing are endangered the bigger following problem of rugged surroundings at dust, smog, high-temperature gas, harmful gas in the abominable place of environment:
1. because of falling to being attached to the camera lens surface, various flue dust make taken the photograph image blurring unclear.
2. when laying, a high position is difficult for maintenance.
3. in high temperature, humidity, harmful gas discharges when using in the big environment, and the video camera life-span is short, even may not realize camera supervised.
Three. summary of the invention
The utility model be solved exist in the background technology image blurring unclear, maintenance is difficult, the video camera life-span short, difficultly realize technical matterss such as monitoring, and provides a kind of materials such as screen isolation harmful gas, dust that form with air-flow to contact with camera lens or fall to being attached to the lip-deep dustproof dirt-proof protector of camera lens.Can be implemented in the rugged surroundings, monitor with pick-up lens.
Technical solution of the present invention is: a kind of air-flow isolated camera lens dust-proof device comprises camera head protecting housing, ring conical flow screen generator, air strainer, air reducing valve and source of the gas.Its special character is: pick-up lens is enclosed in the protection housing; a ring conical flow screen generator is set before camera lens; the source of the gas of air-flow is to be stored in the air-capacitor after clean air is compressed; pressurized air after filtration, be input in the air-flow screen generator after being decompressed to the atmospheric pressure value that needs during monitoring; from the taper slit, eject; form the conical flow screen, thereby cut off dust, harmful gas contacts with pick-up lens.When stopping to monitor, source of the gas is closed, and the protective cover of the similar camera lens lid of device on air curtain generator is closed automatically.
Above-mentioned air screen generator is made up of annular casing and taper slit regulating ring two parts, and two parts wherein form an annular gas storage cavity and conical ring slit with being threaded.
There is the protective cover of a similar camera lens lid side of above-mentioned air screen generator.
Above-mentioned protection housing is made up of protection tube and rear end cap, and its left end has a hole that is complementary with the camera lens extension, and right-hand member hole and camera physical dimension are complementary.Video camera can be come in and gone out, and uses thread connection between rear end cap and protection housing, with the sealing gasket sealing, a cable gateway that can seal is arranged on the bonnet.
Above-mentioned protection housing and camera are solidified as a whole with two rubber rings with sealing, vibration isolation, fixation.
Link with spiral shell formula or the face of being slidingly matched between above-mentioned air screen generator and the protection tube.The distance of air screen and camera lens can be reconciled easily according to focal length.
The right side wall of the annular air storing cavity of above-mentioned air screen generator is provided with small pore, has guaranteed the flow direction and the isolation effect of ring conical flow.
The source of the gas of said flow is the clean compressed air that pressure, flow are complementary with it.
Above-mentioned protective device has the gimbals that are used for fixing.
The present invention has following advantage:
1. the clear picture of being taken the photograph.
2. without the maintaining camera lens.
3. in high temperature, humidity, harmful gas discharges when using in the big environment, and the video camera life-span is long.
4. in rugged surroundings, can realize camera supervised.
5. applied range.Housing can be according to the shape and the bodily form design of camera, and the position of air-flow screen can be reconciled with lens focus, adapts to various situations.
Four, description of drawings
Accompanying drawing is a structural representation of the invention process.
Five, embodiment
Concrete structure of the present invention is referring to Figure of description; camera 6 is arranged in the protection tube 4; the camera lens of camera 6 stretches out from the left end hole of protection tube 4; be provided with the rubber ring 5 of sealing, vibration isolation, fixation between hole and the camera lens; camera 6 is provided with the rubber ring 7 of vibration isolation, fixation near the right part; rubber ring 5 and 7 is fixed on camera in the protection tube 4; protection tube 4 right-hand members are provided with end cap 8; combine as a whole with screw thread; it is empty that end cap 8 centers have lead to come in and go out, and lead is laid in the tube of back airtight.
Be provided with the air-flow screen generator that nozzle transfers ring 1 and nozzle body 2 to form before camera lens, this generator has annular air storing cavity and conical ring nozzle, and the nozzle cross-sectional flow area is adjustable.Annular air storing cavity left side is provided with micropore 3, has air-flow to flow out from the hole, guarantees the conical ring air screen.The right-hand member of nozzle body 2 connects with the mode of screw-type clearance fit, nozzle to camera lens between adjustable apart from lens focus.
Be provided with one in the front or rear side of nozzle and be similar to the camera lens lid, but the over cap of open and close (not drawing in the accompanying drawing) open during monitoring, during non-monitoring and air screen close simultaneously.
The source of the gas of annular air cavity is the pressurized air of pressurized air behind retaining valve 13, gas-holder, switch valve 11, filtrator 10, reduction valve 9 of air compressor 16 outputs.The top pressure of safety valve 13 restriction gas-holder, the ponding in the gas-holder is discharged by draining valve 14, and gas-holder can be several cameras source of the gas is provided.
Above-mentioned concrete structure forms that a kind of air-flow is dustproof every the enclosed camera, anti-fouler.
Above-mentioned principle and structure except that be used for video camera dustproof antifouling, also can be used for other antifouling equipment that need prevent dust.
