Abstract
The invention is applicable to the field of video monitoring, and provides a window glass dew prevention system for a camera housing. The window glass dew prevention system comprises a base frame, a dry coating and an FIR (far infrared) heat generator, wherein the base frame is mounted on the camera housing; the dry coating is applied on one side of the base frame facing to the window glass; and the FIR heat generator is mounted on the other side of the base frame. The window glass dew prevention system has a simple structure and is easy to realize, and can promote the heat conduction through the FIR radiation generated by the FIR material and the dry coating. The window glass dew prevention system is directly mounted in a position close to the window glass of the camera housing, and can improve the heat conduction speed and reduce the heat dissipation; and the dry coating can adsorb vapor through biological carbon to effectively prevent the formation of dews on the inner wall of glass, thereby ensuring the cleanliness of the window glass. In addition, the simple mounting process of the system can greatly improve the production efficiency; and the heat radiation can also heat the camera and the lens close to the window glass to ensure the normal operation of the electrical apparatuses.
Description
Technical field
The invention belongs to field of video monitoring, relate in particular to a kind of sight glass anti-condensation system that is used for camera protective cover.
Background technology
At present, camera protective cover generally all requires to adapt to rugged environment, and wherein under low temperature environment, because dewpoint temperature is very low, the sight glass surface of camera protective cover has the dewfall phenomenon, causes the video camera imaging in the protective cover unintelligible.The dewdrop of sight glass outer wall can be removed by rain brush, but the glass inwall is often just felt simply helpless.
The sight glass heating anti-condensation system of traditional cameras protective cover probably is divided into two kinds.A kind of by resistance heating element and fan composition, mainly be to have utilized conduction of heat, resistance heating element produces heat after energising, calorie spread is given the air of periphery, slowly propagates through air again, makes near the air heating of glass inwall, the temperature dew point of lifting glass inwall air, prevent dewfall, utilize fan to quicken circulation of air usually, improve heat conduction efficiency.Another kind is to glass inwall plating one deck waterproof membrane, waterproof membrane has increased the water wettability of glass surface, making that the steam of protective cover inside is easier assembles at glass inner side, thereby make steam form many large water drop, the globule is under the effect of gravity, from landing on glass, thereby avoided the problem of glass " dim ".
First kind of system's heat transfer rate is slower, and is placed on the back of video camera and camera lens usually, and away from sight glass, often heat has left much to the guard shield external world by the guard shield housing in transmittance process.Second kind of system reduced the transmittance of glass owing to plated waterproof membrane at glass surface, can not be applied in requirement than on the higher camera protective cover; And the meeting on glass that the big globule that drips streaks leaves vestige, also can affect to video camera imaging.
Summary of the invention
It is reasonable to the invention provides a kind of design science, the sight glass anti-condensation system that is used for camera protective cover simple in structure.
The present invention is achieved in that a kind of sight glass anti-condensation system that is used for camera protective cover, it is characterized in that described system comprises pedestal, dry coating and far infrared heater; Described pedestal is installed on the described camera protective cover, and described pedestal applies described dry coating towards described sight glass one side, and opposite side has been installed described far infrared heater.
Advantage of the present invention and good effect are:
Sight glass heating anti-condensation system architecture of the present invention is simple, is easy to realize, has quickened heat conduction by the far infrared wave radiation that far-infrared material and dry coating send; The present invention directly is installed to the position of camera protective cover near sight glass, and heat transfer rate is very fast, and heat dissipation capacity reduces; Dry coating utilizes charcoal absorption steam effectively to guarantee the anti-condensation of glass inwall, has guaranteed the cleanliness of sight glass.In addition, simple mounting process has improved the efficient of production operation greatly; Heat radiation heats for video camera and camera lens near sight glass, guarantees that electrical part normally moves.
