Abstract
The utility model relates to a novel pneumatic infrared thermography lens protection control system comprising a dustproof cover and a pneumatic control system. The pneumatic control system shares a gas source with a gas-type dustproof device. The pneumatic control system comprises a pressure-reducing valve, a pneumatic triple piece, a one-way valve and a gas tank. The gas tank is communicated with a pneumatic reversing valve, the gas flows to a swing cylinder through the pneumatic reversing valve, the dustproof cover is arranged on a rotary shaft of the swing cylinder, and the swing cylinder controls the swinging of the dustproof cover. The lens protection control system is characterized in that the pressure-reducing valve is communicated with an overflow valve through an air filter, and the overflow valve is communicated with a commutation pore of the pneumatic reversing valve through a quick exhaust valve. The beneficial effects of the lens protection control system are that the motion of the dustproof cover is synchronized with the opening/closing of the lens dustproof device, and the lens protection control system is of simple structure and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of thermal infrared imager protection system, particularly relates to a kind of infrared thermal imagery lens protection system.
Background technology
Along with the fast development of infrared imaging, thermometry, the application that metallurgy industry utilizes infrared thermography to monitor production equipment is more and more universal.But, metallurgy industry workshop environment is more severe, high dust atmosphere wherein particularly, can impact infrared thermography, the accumulation of dust on infrared lens front lens outside surface, can cause infrared thermography cannot normally work (infrared image quality declines, temperature measurement accuracy declines), and may cause the front lens wearing and tearing of infrared lens.So, in use must take dust prevention, infrared lens is protected, reduce the impact of dust on the normal work of infrared thermography, prevent the wearing and tearing that dust causes infrared lens.
At present, generally adopt and before infrared lens, install protecting window additional and protect, and at dust accumulation when affecting infrared thermography and normally work, manually protecting window is cleaned, very trouble.This safeguard procedures can only increase the protection to infrared lens, prevent the damage of infrared lens; But obviously can not solve root problem, i.e. the affect problem of dust on the normal work of infrared thermography.This measure protection effect is poor, and maintenance cost is high.
Also have to adopt and compared with labyrinth, infrared thermography is protected, see utility model patent: protective clothing of thermal infrared imager (Granted publication CN201548329U).The application number that applicant submits to is 201320332983.X, and the utility model patent of a kind of new infrared thermal imagery of patent name lens cleaning holding device is simple in structure, also can protect preferably dust and enter camera lens surface, and this two patent is gas type dust guard.
But above-mentioned camera lens dust guard is all keep camera lens under working condition clean; and once these devices quit work; effective len just; need manually with lid, to be covered again; or adopt other control systems that the outer end of protective device is covered; but prior art all cannot guarantee to use immediately cap covers when clean holding device quits work, and complex structure, and manufacturing cost is high.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art; a kind of Novel air dynamic formula infrared thermal imagery lens protection control system is provided; can guarantee immediately the protecgulum of clean holding device to be covered when pneumatic type dust guard quits work; and structure is also very simple, cheap for manufacturing cost.
The technical scheme that the utility model adopts is: the utility model comprises dust cap and atmospheric control, described atmospheric control and gas type dust guard share source of the gas, described atmospheric control comprises reduction valve, pneumatic triple piece, retaining valve and the gas tank connecting successively, gas tank is also communicated with air operated reversing valve, gas flows to tilt cylinder through air operated reversing valve, dust cap is installed in the rotating shaft of tilt cylinder, tilt cylinder is controlled the swing of dust cap, reduction valve is connected by air strainer and surplus valve, and surplus valve is connected by the commutation pore of fast-discharge valve and air operated reversing valve.
Press such scheme, described air strainer is the air strainer in pneumatic triple piece.
Press such scheme, described air operated reversing valve is connected by flow speed control valve and tilt cylinder.
Press such scheme, described tilt cylinder and dust cap are more than two, between the corresponding air admission hole of all tilt cylinders, are connected in parallel.
Principle of work of the present utility model is: the source of the gas of this device and gas type dust guard share source of the gas, and when source of the gas is ventilated, air-flow reaches working pressure through reduction valve, is divided into 2 branches after the air purifier in three linked piece.Branch 1 the flow through reduction valve of three linked piece and oil mist separator, retaining valve, be further divided into 2 branches, and branch 11 is to gas tank inflation, branch 12 air operated reversing valve of flowing through.Branch 2 surplus valve of flowing through, now surplus valve conducting, gas flow is through fast-discharge valve, air operated reversing valve, and air operated reversing valve commutation is conducting position.The now 12Yu of branch branch 121 conductings, air-flow, through the reversal valve branch 121 that flows through, makes tilt cylinder action through flow speed control valve, and tilt cylinder rotating shaft drives dust cap to rotate, and dust cap is opened, thermal imaging system normal imaging.When source of the gas is died or when air pressure is not enough, surplus valve cut-off, fast-discharge valve to the gas in the middle of air operated reversing valve pipeline is discharged rapidly through fast-discharge valve, air operated reversing valve spool is returned to overflow position under the pressure of spring, the now 12Yu of branch branch 122 conductings, gas flow in gas tank promotes tilt cylinder 8,10 action in the other direction through branch 11, branch 12, branch 122, and dust cap cuts out, and thermal imaging system stops imaging.
The utility model beneficial effect is:
1, owing to entering the gas of the gas of high-pressure pressure-reducing valve and the air intake opening of gas shield formula infrared thermal imagery camera lens dust guard, share source of the gas, therefore when the source of the gas of dust guard is not enough to meet the demands, and while needing Pneumatic cover to cover the gas curtain outer ring of clean holding device, control system in the utility model will cover gas curtain outer ring by synchro control Pneumatic cover, not free poor;
2, structure of the present utility model is compared electrodynamic type and electric hybrid simply too much, cheap for manufacturing cost.
