FIELD: photographing and video filming. ^ SUBSTANCE: invention relates to devices providing overwater and underwater photographing and video filming of objects at depth up to 160 m. Proposed device consists of container for camera with ring-shaped housing and end face made in form of ring platform relative to which cover with eccentrically displaced window is installed, being provided with glass resting on toroidal section ring seals fixed from displacement by semitoroidal grooves. Second cover is provided with dummy holes in which lock and control push-buttons are installed. Threaded holes are made from side of end face relative to which second cover is secured by screws and layer of glue. Spring provides stable flexible position of push-buttons relative to end faces of blind holes. Inner surface of housing is made in form ring surface with bevel and semitoroidal section ring grooves. Housing with third cover is installed from side of end face of second cover, said housing being furnished with sealed-contact reed relays with conductors and intersected by holes. Third cover is intersected by threaded holes and holes. Device for video shooting and/or photographing is installed from inner side of glass. Element for interaction of reed relays with conductors is provided which is installed in control push-buttons with spheroidal surface and recesses for interaction with User to control device at video-filming or photographing with preservation of exact orientation of position of control push-buttons. Blind ring holes for spring with surfaces are made in housing grooves. Seals are installed relative to bevel surfaces of toroidal form in section. Seals interact with second cover provided with threaded holes relative to eccentrically displaced hole in second cover. Semitoroidal grooves are made from side of end face surface for fitting glass relative to toroidal seals installed relative to surfaces. Glass is secured by second cover by means of glue from side of end face. First cover is made with cylindrical profile and is provided with end face changing into rectangular slot. Step of cylindrical surface is furnished with grooves semitoroidal in section. Mounting holes are made from end face for fitting threaded fasteners which provide fastening of L-shaped post with working shelf in which slot is made for fasteners. Fasteners are installed in threaded holes. First cover is provided with window for surveying underwater or overwater shelf. For this purpose it has fin with holes designed for fastening lighting elements and interconnection with support plate having threaded and combination holes providing connection with ring-shaped housing. Opposite plate is provided with combination and threaded holes for its fastening on housing and rigid tie with handle with curvilinear hole made in form of slot with surfaces. Peripheral part of handle has different inner profiles which, with account of surfaces, make it possible to effectively hold the device for video filming and photographing in working position. First cover is secured by self-clamping elements and is held relative to ring-shaped housing is rigid position. Housing of control panel is made in form of shaped shell with surfaces and threaded holes and is arranged inside ring-shaped housing. Moreover, housing is provided with coaxially arranged ring rectangular-section projections of inner profiles of surfaces. Working space serves for accommodating camera and liquid-crystal display transmitting picture from camera through window installed relative to window. Through holes are made in zone of ring surface providing penetration of water under glass of light filter connected with ring toroidal seal which are installed by means of flexible spheroidal vacuum element provided with handle. Hand le of container is provided with curvilinear closed hole. Flange is provided with holes for mounting on intermediate element with steps of coaxially arranged projections with different diametric surfaces providing mounting of flexible seals relative to end faces. End faces from side of sight glass are installed in ring slots from side of end face surface. Simultaneous crumpling of ring seals is reduced owing to provision of bevels inside housing. Size of port light glass is increased proportionally to pressure of water at depth up to 190 m, and thickness of glass of light filter does not depend on pressure of water column at depth of diving of driver. ^ EFFECT: improved quality of video filming and photographing. ^ 7 dwg |
