Abstract
The invention relates to a high temperature-resisting protecting jacket for a camera, which comprises a jacket body and a rear cover, and is characterized in that the jacket body is formed by fixedly connecting a front flange, a sleeve and a rear flange; the front flange consists of an outer air curtain coat and an inner air curtain coat; the section of the inner air curtain coat is rectangular and four top corners of the rectangular section are welded on the inner wall of the barrel-shaped outer air curtain coat; and an air cooling channel is formed by a gap among four edges of the inner aircurtain coat and the outer air curtain coat. The high temperature-resisting protecting jacket has the advantages that as being a cooling and protecting device for a monitoring camera, the jacket has strong decay resistance, can prevent water and dust and save raw materials, has high cost performance and long service life, is convenient and safe to operate, and can work stably for a lone time under severe environments of being high in temperature, full of dust,and moisture, easy for corrosion and the like.
Description
Technical field
The present invention relates to the rig camera annex, particularly the high temperature resistant protective jacket of a kind of video camera is adapted under the hot industry production line condition of industries such as iron and steel, electric power, metallurgy, cement, petrochemical industry, uses as rig camera cooling and protection.
Background technology
Camera protective cover is the significant components in the supervisory control system, and the reliability for the protection of video camera and camera lens work prolongs its useful life.In addition, protective cover can also prevent the artificial destruction to video camera and camera lens as far as possible.Common outdoor pick-up machine protective cover only is applicable to the outdoor monitoring under the general environment, is applicable to ambient temperature-5～45 ℃.But for the radiation temperature at 150 ℃ at the scene of the hot industry production line of industries such as iron and steel, electric power, glass, cement and petrochemical industry, common outdoor pick-up machine protective cover can not meet the demands far away.
1. the problem that prior art exists comprises that common outdoor pick-up machine protective cover generally uses aluminium, common iron or plastics to make, and can't adapt to high temperature, the highly corrosive environments of industries such as iron and steel, petrochemical industry, electric power, metallurgy, cement.2. the air-cooled protective jacket that in the past used, profile is bigger, and is not attractive in appearance.3. bigger owing to profile, so the cost height.4. camera mount is fixed in the cover, inconvenience during Installation and Debugging.
Therefore, the novel video camera of design research and development with high temperature resistant protective jacket for the reliability of protecting video camera and camera lens work, reduce cost, conveniently use and prolong its useful life and have important function.And present domestic colleague does not have this type of video camera to occur with high temperature resistant protective jacket as yet, does not see that document has the report of technical article in this respect yet.
Summary of the invention
Purpose of the present invention is exactly for overcoming the deficiencies in the prior art, provide a kind of video camera that adopts novel safeguard structure and air-cooled structure with high temperature resistant protective jacket design, the video camera inner room is isolated from the outside, blocking-up flue dust, rainwater etc. are to the pollution of video camera and camera lens, the air curtain structure can make cold gas discharge from camera window simultaneously, and camera window glass is also played cooling and dustproof effect.
The present invention realizes by such technical scheme: the high temperature resistant protective jacket of a kind of video camera, comprise body and bonnet, and it is characterized in that body is formed by fixedly connecting by forward flange, sleeve and rear flange; In forward flange, put into preceding sealing ring, high temperature resistant optical glass successively, and with the glass back-up ring it is compressed;
Forward flange is made of cover in air curtain overcoat and the air curtain, and the cover cross section is rectangle in the air curtain, and four drift angles of rectangle are welded on the inwall of tubular air curtain overcoat, and four limits of cover and the gap between the air curtain overcoat form air-cooled passage in the air curtain;
Bonnet is welded as a whole by camera mount, locking mother, cold gas air inlet and rear end cap and constitutes.
Advantage of the present invention is: video camera adopts stainless steel with high temperature resistant protective jacket, and decay resistance is strong.As rig camera cooling and protection, water proof and dust proof is applicable to that radiation temperature is lower than 150 ℃ of any high temperature scenes, and protection effect is good; Save raw material, the cost performance height; Easy-to-operate; Long service life; Be widely used in iron and steel, electric power, glass, cement, the hot industry production line of industries such as petrochemical industry.Can be at various high temperature, many dust, many moistures, therefore long-term stable operation under the adverse circumstances such as many corrosion has vast market prospect.

Embodiment
For a more clear understanding of the present invention, describe the present invention in conjunction with the accompanying drawings and embodiments in detail:
As shown in Figures 1 to 4, body 1 is formed by fixedly connecting with rear flange 16 by forward flange 14, sleeve 15; Sealing ring 13, high temperature resistant optical glass 12 before in forward flange 14, putting into successively, and with glass back-up ring 11 it is compressed;
Forward flange 14 is made of cover 142 in air curtain overcoat 141 and the air curtain, cover 142 cross sections are rectangle in the air curtain, four drift angles of rectangle are welded on the inwall of tubular air curtain overcoat 141, and four limits of cover 142 and the gap between the air curtain overcoat 141 form air-cooled passage in the air curtain;
Bonnet 2 is welded as a whole with rear end cap 22 by camera mount 21, locking mother 23, cold gas air inlet 24 and constitutes;
During use, at first video camera 3 and camera mount 21 have been screwed front and back position;
Water joint 4, flexible conduit joint 5 screw in, tighten from locking female 23 two ends respectively.
Described forward flange 14, sleeve 15, rear flange 16, camera mount 21, cold gas air inlet 24 all adopt stainless steel to make with rear end cap 22;
Video camera is isolated from the outside the video camera inner room with high temperature resistant protective jacket, and blocking-up flue dust, rainwater etc. are to the pollution of video camera and camera lens, and cold gas also plays cooling and dustproof effect from the air curtain of camera window discharge to camera window glass simultaneously.
Air cooling system: adopt the air blast cooling mode.Cold gas is from cold gas air inlet 24 air inlets of protective jacket rear end cap 22, video camera 3 and camera lens directly carried out air-blowing sweep, and discharges from the camera window periphery and forms gas curtain.So, cold gas has been carried out high temperature protection to camera system, and the gas curtain that forms during discharge makes camera window glass not be subjected to smoke contamination.
According to the above description, can realize the solution of the present invention in conjunction with art technology.
