Abstract
An observation port for a camera protective sleeve used under high temperature and smoke dust environments comprises a view port used for setting a camera lens on one side thereof, and is characterized in that the view port is arranged at the top end of a conical cylinder, an outer cylinder is sheathed outside the conical cylinder, and a ring-shaped airflow passage is formed between the inner wall of the outer cylinder and the outer wall of the conical cylinder. The observation port has reasonable structure and design, and can form a dense air curtain on inside the observation port via two air inlet ways of the view port and the ring-shaped airflow passage around the view port, so as to prevent dust depositing in the observation port, prolong the cleaning period of the observation port, effectively eliminate the damage due to the inside high temperature and smoke dust environments, prevent the high temperature air on the inner side radiating and entering the observation port, and prevent the damage to the camera and the lens due to high temperature. The observation port reduces the workload of equipment maintenance, improves the stability of process parameters and the yield and the quality of product, and can be widely used for the observation ports of various camera protective sleeves under various high temperature and smoke dust environments.
Description
Technical field
The invention belongs to shoot and monitor device utility appliance technical field under high temperature, the flue dust environment, be specifically related to the viewport of video camera protective sleeve under high temperature and the flue dust environment.
Background technology
All there is the high-temperature smoke environment in industries such as steel-making, cement, pottery, glass; the industrial camera that is used for surveillance equipment operation or state of arts under this environment must be installed in the protective sleeve; the protective sleeve that has also needs water-cooled, before the camera lens viewport will be set on protective sleeve.Need to feed gases such as pressurized air or nitrogen in the general protective sleeve; the gas that feeds damages video camera and camera lens from the camera aperture ejection on the protective sleeve so that prevention outside heat and flue dust enter protective sleeve by viewport; but generally; dust can be cumulative on the protective sleeve viewport, until almost blocking viewport.So just have to often clear up the dust on the viewport, this not only increases the plant maintenance workload, influences picture quality, and also can influence technological parameter and product quality in some industry.
For example, in float glass,, need insert many spys industry camera systems from the molten tin bath both sides for position, width of glass sheet variation and the edge machine impression coincidence situation of sight glass limit portion in molten tin bath.This system mainly is made up of industrial camera and outer protection water jacket; logical nitrogen in the water jacket; this is because the glass plate in the molten tin bath is to swim on the tin liquor that is in melting state; and the as easy as rolling off a log oxidation of the tin of melting state; the oxidation of tin not only makes tin suffer a loss; and even more serious be tin oxide attached on glass, cause the glass degradation or become waste product.Therefore; need be under the prerequisite that feeds nitrogen hydrogen hybrid protection gas in the molten tin bath strict seal; but; in order to remove attached to the tin ash on the molten tin bath spy industry camera system water jacket viewport, have to often will protect water jacket to be extracted out, cause a large amount of air to infiltrate in the molten tin bath; cause the tin amount of oxidation to increase; glass edge portion temperature variation, thus glass quality influenced, and increase the consumption of tin.
The utility model content
The purpose of this utility model is to provide a kind of reasonable in design; can be under inboard high temperature that forms fine and close gas curtain of viewport and flue dust environment the viewport of video camera protective sleeve; this viewport can effectively be eliminated inboard high temperature and flue dust environment damage; form gas curtain in the inboard of viewport and stop the deposition of dust at viewport; prolong the cleaning cycle of viewport; and prevent that inboard high-temperature gas from entering viewport by viewport and radiation, avoid the destruction of high temperature to video camera and camera lens.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The viewport of video camera protective sleeve under a kind of high temperature and the flue dust environment; comprise that a side is used to be provided with the peephole of camera lens; the opposite side that it is characterized in that described peephole is provided with conically shaped, and a urceolus is put in the installing of conically shaped overcoat, forms annular air-flow path between described outer tube inner wall and conically shaped outer wall.
Concretely, described peephole is the through hole that is positioned at the vertex of a cone position of conically shaped, and the air intake opening that the periphery of peephole is provided with annular communicates with annular air-flow path.
The vertex of a cone end that the cylindrical cylindrical shell of the outer wall of described urceolus, an end of its inwall inwardly are convexly equipped with back and conically shaped fixedly installs, the inside indentation of the inwall other end, the suitable gas vent of internal diameter at the bottom of the awl of formation and described conically shaped.
Described urceolus and the coaxial setting of conically shaped, the awl bottom that the inwall other end of urceolus extends and is longer than conically shaped, the inboard gas curtain district that forms, at the bottom of the described awl and the end of the inwall other end of urceolus.
Described urceolus and the coaxial setting of conically shaped, inwall one end of urceolus extends and is shorter than the vertex of a cone end of conically shaped, and peephole is arranged on the boss that cone top part forms in urceolus.
Described peephole is the through hole that is positioned at the vertex of a cone position of conically shaped, and the inlet hole that the periphery of peephole is provided with annular spread communicates with annular air-flow path.
The viewport of video camera protective sleeve is by feeding the protection air-flow under this high temperature and the flue dust environment in the annular air-flow path of peephole and peephole periphery; form stable and cause the gas curtain that closes at the opposite side of viewport; this gas curtain forms isolated area; can stop on the one hand dust to form dust stratification at the peephole place, the high-temperature gas that prevents gas curtain one side on the other hand enters and sees through peephole behind the bellmouth video camera and camera lens are damaged.Peephole is formed at the vertex of a cone end of conically shaped, can form bigger observation space, improve the observing effect of camera lens, and the urceolus of conically shaped arranged outside can form the gas channel of annular with conically shaped, and this gas channel guiding recycle stream forms stable and fine and close gas curtain district at the awl bottom of a conically shaped air-flow with peephole.In order to improve the compactness of gas curtain, the outer tube inner wall in gas curtain district can be arranged to oblique interior indentation structure, and the awl bottom of conically shaped is stretched out in this end of urceolus.
Airflow inlet as for gas channel one side can be annular mouth, also can be the manhole of annular spread.
The beneficial effects of the utility model are; the viewport reasonable in design of video camera protective sleeve under this high temperature and the flue dust environment; two groups of intake types of annular air-flow path by peephole and periphery; can be at the fine and close gas curtain of the inboard formation of viewport; stop the deposition of dust, prolong the cleaning cycle of viewport, effectively eliminate inboard high temperature and flue dust environment damage at viewport; and prevent that inboard high-temperature gas from entering viewport by viewport and radiation, avoid the destruction of high temperature to video camera and camera lens.This viewport has alleviated the plant maintenance workload, has improved the stability of technological parameter and the output and the quality of product, can be widely used in the viewport of the video camera protective sleeve under various high temperature and the flue dust environment.
