Abstract
The invention discloses a monitoring equipment internal lens fogging prevention device comprising a lens and protective glass. A shading sealing sleeve is installed on the lens. The other end of the shading sealing sleeve is connected with protective glass in a contact and sealing way. The whole shading sealing sleeve is airtight. The monitoring equipment internal lens fogging prevention device has characteristics that lens fogging can be avoided, image spots can be reduced, the structure is simple and cost is low.
Description
Technical field
The invention belongs to video monitoring equipment technical field, particularly a kind of device preventing watch-dog internal lens from hazing.
Background technology
CCTV camera is under the temperature difference, climatic influences, saturated steam chance in its inner air is cold can produce condensation, because the strong, weak of cold environment condenses into frost and mist respectively, affects observing effect, and once above phenomenon appears in camera lens, watch-dog also loses its effect naturally.The anti-method of hazing common at present has following several: 1) design defrosting circuit: video camera starts heater and defrosts 0 DEG C time, but is the increase in power consumption, adds volume; 2) fan is set: when temperature is higher than 50 DEG C, automatically starts fan and carry out air draft cooling, utilize equipment inner air and outer air to circulate except fog, but when device external ambient humidity is larger, poor effect, and equipment non-tight, be affected by the external environment large, easy-to-rust, component aging, affects useful life; 3) device interior inflated with nitrogen: without steam, nature can not haze, but it is high to there is product casing design precision, and technological level requires high; 4) put drier: removing internal steam, but grown and can lose efficacy, and loses the effect preventing from hazing the drier time.All there is certain drawback in above several method.
Summary of the invention
The object of the invention is to improve prior art not enough and provide a kind of and avoid camera lens to haze, reduce image spot, structure is simple, cost the is low device preventing watch-dog internal lens from hazing.
The object of the present invention is achieved like this, the device preventing watch-dog internal lens from hazing, comprises camera lens, protective glass, is characterized on camera lens, be provided with shading sealing shroud, the shading sealing shroud other end contacts with protective glass and is tightly connected, and shading sealing shroud entirety is airtight.
In order to realize object of the present invention further, can be one end that described shading sealing shroud is connected with camera lens being cylindrical and having elasticity, its diameter be less than the diameter of camera lens and be socketed on camera lens.
In order to realize object of the present invention further, can be between described shading sealing shroud and camera lens, between shading sealing shroud and protective glass, scribbling bonded adhesives.
In order to realize object of the present invention further, can be described shading sealing shroud and protective glass contact jaw for flexible tubaeform, form sucker structure.
In order to realize object of the present invention further, can be that described shading sealing shroud adopts silica gel material to make.
In order to realize object of the present invention further, can be camera lens, shading sealing shroud, protective glass formed seal cavity in humidity be less than 6%.
Compared with the prior art the present invention has following distinguishing feature and good effect: the present invention is provided with shading sealing shroud on camera lens, shading sealing shroud entirety is airtight, the other end contacts with protective glass and is tightly connected, such camera lens is arranged in airtight space, so both can prevent the air outside shading sealing shroud from entering, avoid the generation of fog, also can block the Infrared of being launched by watch-dog self infrared lamp and enter camera lens, prevent phenomenon image occurring hot spot, improve the definition of monitoring image; One end that shading sealing shroud is connected with camera lens is cylindrical and has elasticity, and its diameter is less than the diameter of camera lens and is socketed on camera lens, installs more for convenience, ensure that sealing simultaneously; Be provided with adhesive linkage between shading sealing shroud and camera lens, between shading sealing shroud and protective glass, make to combine between shading sealing shroud and camera lens, between shading sealing shroud and protective glass closely by adhesive linkage, good airproof performance, improve anti-ly to haze, anti-hot spot effect; Shading sealing shroud and protective glass contact jaw are flexible tubaeform, form sucker structure, camera lens, shading sealing shroud form sucker, air pressure is utilized to be pressed on protective glass by shading sealing shroud, a seal cavity is formed in shading sealing shroud, can prevent the air outside shading sealing shroud from entering, under the prerequisite not affecting equipment performance and outward appearance, effectively prevent video monitoring equipment internal lens to haze the generation of phenomenon; Humidity in the seal cavity that camera lens, shading sealing shroud, protective glass are formed is less than 6%, can avoid the generation of fog.
