Abstract
The utility model relates to an anti-explosion camera, which comprises a casing and a cover body, wherein the casing and the cover body are mutually matched, a camera assembly is arranged in a cavity formed between the casing and the cover body, the casing is made of light metal materials, the cover body is provided with a transparent part, and the cover body and the casing are connected in a screw thread fastening mode. Because the casing and the cover body adopt the screw thread fastening mode for replacing the fastening mode only through screws in the prior art, hole drilling on the casing is not needed, and the casing does not need to be thickened, so the size of the whole camera is greatly reduced, and the weight of the casing is reduced. In addition, because the steps of processing a plurality of holes in the prior art are omitted, the processing process is more simplified, the processing precision requirement is reduced, in addition, compared with the single screw connecting mode, the screw thread fastening mode has the advantages that the connection is firmer because the contact area of the casing and the cover body is increased, the tension-resistant and impact-resistant intensity is higher in the explosion environment, and the anti-explosion effect is better.
Description
Technical field
The utility model relates to camera, relates in particular to a kind of explosion-proof type camera.
Background technology
Places such as warehouse at hazardous materials transportation vehicle, hazardous materials transportation boats and ships, storage combustible and explosive articles, needing to install camera monitors, because aforementioned occasion security requirement is higher, therefore used camera will satisfy little, in light weight, the safe and reliable condition of volume.
At present, most of camera glass cover adopts the fixing production method of a plurality of flame proof screw borings, for making glass and shell wall be not easy explosion, can only thicken shell wall, this can cause whole camera volume big, Heavy Weight, therefore application can't be installed in particular surroundings or small space at all, simultaneously, the mode that this boring screw is fixing is fixed together because housing and lid only depend on the small size at screw place to contact, stretching resistance is not strong, under explosion environment, strong wallop makes the easy and housing disengaging of lid easily, in addition, the machining accuracy height that bore mode requires, the processing technology complexity.Further, the explosion-proof infrared camera of existing integral type, though degree of protection can adapt to requirement, but do not consider to put in place for the influencing factor of environment, such as influences such as dust, rainwater, because camera and infrared lamp are arranged in the same shell, infrared lamp is by reflections such as glass, dust, rainwater, can cause picture that problems such as aperture, picture be greyish white are arranged, influence picture quality and video monitoring range greatly, make video monitoring lose meaning.
The utility model content
The utility model purpose is, a kind of explosion-proof type camera is provided, and structure is light and handy, is convenient to install.
For solving the problems of the technologies described above, a kind of explosion-proof type camera of the present utility model, comprise the housing and the lid that cooperatively interact, in the cavity between housing and the lid CCD camera assembly is set, described housing adopts lightweight metal material to make, described lid has hyalomere, and described lid and described housing link together by the mode of screw threads for fastening.
Preferably, described lid comprises a framework, and hyalomere is arranged on the framework.
Preferably, described hyalomere is a crown class fluorophosphate implosion guard product.
Preferably, the lateral wall on the described framework is provided with screw thread, and the madial wall of described housing is provided with respective threads.
Preferably, described housing is an articles made of aluminium alloy.
Preferably, described housing is that the aluminium alloy of ZL104 is made by the trade mark.
Preferably, also comprise an infrared lamp assembly, be arranged on outside the cavity of described housing and lid formation.
Preferably, described infrared lamp assembly is provided with a switch, and described switch obtains brightness value, and when illumination was lower than predetermined value, described switch was opened the infrared lamp assembly automatically.
Preferably, an introducing assembly that is used to seal the gap of external cord and housing cavity also is set on the described housing.This introducing assembly can isolate gaseous state and liquid infiltrates the housing cavity, thereby plays explosion-proof effect
Preferably, a pressure ring is set also on the described framework, with described hyalomere butt.
Compared with prior art, of the present utility model have a following advantage:
1, the utility model integral body has adopted lightweight metal material, housing integrated design moulding, housing and lid adopt the mode of screw threads for fastening to replace the mode that only depends on screw in the prior art, not be used in a large amount of hole of brill on the housing, needn't add thick shell, thereby can reduce the volume of whole camera greatly, alleviate case weight, and owing to save the step in a plurality of holes of processing in the prior art, processing technology is more simplified, the required precision of processing reduces, and the mode of this screw threads for fastening compares single screw ways of connecting, because housing increases with the lid contact area, makes that connection is more firm, under explosion environment, tension, impact strength is higher, so the connection of screw threads for fastening mode, and explosion-proof effect is stronger;
2, further, the mounting structure that the utility model takes camera, infrared lamp to separate, thereby clear picture, the scope that take night are wide, can eliminate infrared light reflection problems such as glass, dust, rainwater, have improved picture quality greatly.
3, further, the hyalomere of lid adopts crown class fluorophosphate implosion guard, uses crown class fluorophosphate implosion guard, and the light passband is higher than 92%, eliminates the reflection of infrared lamp halation and dust fully.This infrared separated structures of the present utility model cooperates multiple focal length lens, has the outer visual range of 15 silver pink, and infrared lamp was opened automatically when visible light was not enough, can use preferably when night and light are relatively poor.
