Background technology
Explosion-proof dust-ignition-proof type video camera is as the headend equipment of explosion-proof video monitoring command system closed-circuit TV system, undertaking the task of the real-time high-quality collection of image scene and fast-response control instruction, the running quality of whole video monitoring and commanding system is being played crucial effects.Explosion-proof dust-ignition-proof type video camera need satisfy the instructions for use of very special environment such as IIC gas group following (being typically hydrogen, acetylene, ethene, coke-stove gas, dimethyl ether etc.) and combustible dust, its manufacturing need meet IEC60079, IEC21641, the regulation of GB3836-2000 and GB12476.1-2000 standard; The video camera of present employed identical function mostly is branch body structure (for example disclosed video camera of Chinese patent literature notification number CN2904028), cable between each unit connects and exposes, volume is big, Heavy Weight, rotating speed is slow, the presetting bit precision is low, intelligent function does not possess, installation and maintenance difficulty, visual angle are restricted, to shortcomings such as environmental suitability differences.
And advantage such as existing spherical camera has that volume is less, weight is light, rotating speed is very fast, the presetting bit precision is higher, the visual angle is unrestricted, but above-mentioned existing spherical camera does not have explosion prevention function.Because, the transparent ball cover that existing video camera adopted as shown in Figure 6, being connected of the annular installation portion b on a of sphere portion of transparent ball cover and sphere portion a top is almost rectangular, annular installation portion b is arranged on the installation table top c in the spherical camera housing; During use, when a of sphere portion of transparent ball cover was subjected to big external pressure, the junction, right angle of a of sphere portion and installation portion b was because of concentrating stressed easy explosion, so cause existing spherical camera can not satisfy explosion-proof and requirement dust-ignition-proof.
The utility model content
Technical problem to be solved in the utility model provides a kind of explosion-proof spherical camera that can satisfy requirement of explosion proof.
For solving the problems of the technologies described above, explosion-proof spherical camera of the present utility model comprises: the housing of upper and lower settings and one-time formed transparent ball cover; Transparent ball cover comprises: the sphere portion of hollow hemisphere shape and be the flared type installation portion of arc in the cross section on sphere portion top; The bottom of housing is provided with clamping ring, and clamping ring comprises: the connecting portion that is threaded with the bottom interior wall of housing and be connected in the ball cover auxiliary section that the arc outer wall with the flared type installation portion of connecting portion below matches; The flared type installation portion of transparent ball cover is connected on the ball cover auxiliary section of clamping ring by epoxide-resin glue; The threaded engagement face of clamping ring and housing is provided with sealing ring, further to guarantee the sealing of clamping ring and housing.
Further, for making transparent ball cover be fixed on the clamping ring and guaranteeing therebetween sealing, described connecting ring inboard is provided with rubber washer above the edge of the flared type installation portion of transparent ball cover, rubber washer top is provided with the trim ring on the inwall of the connecting portion that is threaded in clamping ring.
Further, for guaranteeing the sealing of power supply and data wire and housing, the sidewall of described housing is provided with opening, this opening is provided with the nut seat that power supply source and data wire pass, and is provided with packing ring, O-ring seal that is enclosed within on power supply and the data wire and the clamp nut that is threaded with nut seat in the nut seat successively.
The utility model has positive effect with respect to prior art: in (1) explosion-proof spherical camera of the present utility model, the cross section of transparent ball cover is that the flared type installation portion of arc and the clamping ring of housing bottom are connected by epoxide-resin glue and realize being sealed and matched; Because the cross section of the flared type installation portion of transparent ball cover is an arc, therefore in use, when the sphere portion of transparent ball cover is subjected to big pressure, transparent ball cover the flared type installation portion stressed evenly and disperse, so be difficult for taking place the situation of explosion.Therefore, explosion-proof spherical camera of the present utility model has not only that volume is less, weight is light, very fast (120 °/s), the advantage of traditional spheroidal video camera such as the presetting bit precision is higher, the visual angle is unrestricted, also have explosion prevention function of rotating speed.(2) in the utility model, the flared type installation portion of transparent ball cover is connected on the ball cover auxiliary section of clamping ring by epoxide-resin glue, because epoxy resin is in colloidal state when gluing connection, the thickness that is beneficial to the epoxy resin between the ball cover auxiliary section of the flared type installation portion of transparent ball cover and clamping ring is evenly distributed, be beneficial to stressed at the flared type installation portion that disperses transparent ball cover, make it stressed evenly, can prevent further that transparent ball cover is because of the unbalance stress explosion; The employing shell is a stainless steel casing, and transparent ball cover can be resisted at least 4 kilograms hydrostatic test.(3) explosion-proof spherical camera of the present utility model is applied to contain the environment of damp or vapour mixture, and the place of containing the combustible dust environment, it can be transformed into signal of telecommunication transmission to on-the-spot image, and can pass through Long-distance Control, changes the operating state of video camera.Be applied to fields such as oil, chemical industry, mining industry, transportation, scientific research.Equipment such as video camera and transmission, demonstration, record are formed the video monitoring command system.
