Background technology
The present general flame proof form of explosion-proof camera shooting instrument, shell requires hermetically sealed design, and available light sees through the transparent body (as tempered glass) of explosion-proof processing, gathered by built-in camera, thus the output of follow-up acquisition image.Emerging thermal imaging, also progressively be applied in the industry monitoring field, its front end image-forming principle and normal image are gathered similar, but be subjected to absorb ultrared restriction in ordinary optical glass, the present forward observation window that generally adopts germanite glass to be used for the hotness video camera, but the hardness of germanite glass and mechanical strength can't satisfy the impulse test of flame-proof type in the explosion-proof criteria.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of anti-explosion thermal-imaging camera front end transparent windows is provided, and it can guarantee that enough infrared rays see through smoothly, are obtained by the thermoinduction video camera, can stop and absorb certain impulsive force again, to meet explosion-proof criteria.
The first kind of technical scheme that realizes above-mentioned purpose is: a kind of anti-explosion thermal-imaging camera front end transparent windows, comprise the front shroud of fixedlying connected with the video camera cylindrical shell, on the endoporus step of front shroud by the interior metallic cover pad that is equipped with successively outward, second germanite glass, the 3rd rubber blanket, metal mesh panels, second rubber blanket, first germanite glass, first rubber blanket, metal washer and glass trim ring, the glass trim ring is connected with the inner hole thread of front shroud, and glass trim ring inboard props up metal washer, metal washer is pressed on first rubber blanket, first rubber blanket is pushed down first germanite glass, first germanite glass is pushed down second rubber blanket, second rubber blanket is pushed down metal mesh panels, metal mesh panels is pushed down the 3rd rubber blanket, the 3rd rubber blanket is pushed down second germanite glass, second germanite glass is pushed down the metallic cover pad, and the metallic cover pad is pressed on the explosion suppresion surface of front shroud.
The mesh of metal mesh panels is a circular port.
The mesh of metal mesh panels is a square hole.
The another kind of technical scheme that realizes above-mentioned purpose is: a kind of anti-explosion thermal-imaging camera front end transparent windows, comprise the front shroud of fixedlying connected with the video camera cylindrical shell, on the endoporus step of front shroud by the interior metallic cover pad that is equipped with successively outward, second germanite glass, the 3rd rubber blanket, metal knitted mesh layer, second rubber blanket, first germanite glass, first rubber blanket, metal washer and glass trim ring, the glass trim ring is connected with the front shroud inner hole thread, and glass trim ring inboard props up metal washer, metal washer is pressed on first rubber blanket, first rubber blanket is pushed down first germanite glass, first germanite glass is pushed down second rubber blanket, second rubber blanket is pushed down metal knitted mesh layer, metal knitted mesh lamination is lived the 3rd rubber blanket, the 3rd rubber blanket is pushed down second germanite glass, second germanite glass is pushed down the metallic cover pad, and the metallic cover pad is pressed on the explosion suppresion surface of front shroud.
After adopting above-mentioned first kind of technical scheme, principle of work characteristic in view of the thermoinduction video camera, simple glass has absorption to infrared ray, and germanite glass is transparent to infrared ray, but germanite glass does not possess the shock resistance of tempered glass, therefore in the arranged outside metal mesh panels of second germanite glass, the size and the distribution density of mesh obtain according to calculating, can guarantee that enough infrared rays see through smoothly, obtained by the thermoinduction video camera, can stop and absorb certain impulsive force again, to meet the impulse test of explosion-proof criteria.One buffer gasket is arranged between this metal mesh panels and the germanite glass simultaneously, both plane is separated and do not contact, and because the specific thicknesses of metal mesh panels, 4 joules of impulsive forces cause deformation excessive and contact with germanite glass when avoiding impulse test.
After adopting above-mentioned another kind of technical scheme, principle of work characteristic in view of the thermoinduction video camera, simple glass has absorption to infrared ray, and germanite glass is transparent to infrared ray, but germanite glass does not possess the shock resistance of tempered glass, therefore at the metal knitted mesh layer of the arranged outside of second germanite glass, the size and the distribution density of mesh obtain according to calculating, can guarantee that enough infrared rays see through smoothly, obtained by the thermoinduction video camera, can stop and absorb certain impulsive force again, to meet the impulse test of explosion-proof criteria.Between this metal knitted mesh layer and the germanite glass buffer gasket is arranged simultaneously, both plane is separated and do not contact, and because the specific thicknesses of metal knitted mesh layer, 4 joules of impulsive forces cause deformation excessive and contact with germanite glass when avoiding impulse test.
