System for production of ferromanganese concretions

FIELD: mining.

SUBSTANCE: invention can be used for development of mineral resources of seas and oceans bed surface at development of gravel deposits of solid minerals. System comprises exploring ship, self-propelled collection machine, connected to pipeline by flexible link, connected to exploring ship pipeline lower end, transport pipeline, buffer storage. At that, system is additionally equipped with unmanned underwater vehicle with spatial thrust vector, equipped with hydroacoustic systems and system for visual observation, where localized buoyancy elements system is included into upper part of mechanical flexible connection, and buoyancy elements distributed system is included into lower part of mechanical flexible linkage between unmanned underwater vehicle and self-propelled collecting unit.

EFFECT: high efficiency of ferromanganese nodules sampling and reliability of system.

FIELD: mining.

SUBSTANCE: invention relates to mining and can be used for dredging soil. The system to extract submerged sediments (3) of the geological allotment and their allotment is considered. From the free floating mining ship (1) the mixture of water and sediment is sucked by the submerged pump assembly through the flexible hose (7) made with the ability of winding on a rotating spool (5) located on the said mining ship when the ship sails over the geological allotment. The sucked mixture is then immediately fed into one of the series of free-floating cargo and transporting assemblies (27), which float along the board side. The system is provided with the length regulators of the suction hose and the length of the hanging ropes.

EFFECT: improving the efficiency of dredging soil.

SUBSTANCE: complex comprises a floating facility, the following components installed on it: a receiving accessory, a lifting single-drum and double-drum scraper hoists, diverting units, head and tail traction ropes, a perforated vessel of rectangular cross section with cutting edges, bottom anchors with buoys. At the same time the head rope is kinematically linked with a longitudinal traction rod and ropes hingedly joined with levers of cutting planes as capable of their rotation to close a vessel base in the form of a spatial frame of square cross section with their closure by side edges, forming faces of a rectangular pyramid aligned with the top outside along the longitudinal axis of the device, the cutting plane of which is arranged in the form of isosceless triangles adjoining hingedly with their bases to bases of the specified frame bases, inside of which there is a screening drum of cylindrical shape, which rests with its circular bands with flanges onto rollers fixed in the inner corners of the frame faces, the cylindrical surface of the screening drum screening is formed by longitudinal bars installed along the cylinder generatrix and fixed on circular bands to form longitudinal slots between them, the cylindrical surface of the screening drum is embraced with ropes fixed on the drum and wound along the helical line, at one side in the right direction, and at the other side - in the left direction, and coming off the drum along the tangent to the cylinder circumference, the device is equipped with a polyspast with a fixed shell of units fixed on the frame, and a movable shell capable of its displacement along the frame face, and the angle of rotation of the screening drum by 360 degrees is provided with the length of the rod travel with the traction rope.

EFFECT: higher efficiency and environmental capability of works in mining of solid minerals from a sea bottom.

FIELD: environmental protection.

SUBSTANCE: invention relates to nature protection. System for collecting waste gas includes sea platform and underwater wells of oil and gas production, floating gas-holder in form of typical tank with strapping with flexible pipes to supply waste “raw” gas from platform and subsea wells for their fractional separation in gas-holder into “dry” gas, formation water and oil. Dry gas under its own pressure extends from gas-holder top via flame arrester, safety valves, partially through automatic controller at specified operating mode of operating plug, and main part of gas is supplied to platform with consequent fuel supply of heat generator. Formation water and oil, collected in gas-holder, are supplied to platform under own pressure for complete utilization.

EFFECT: technical result consists in reliability, safety and environmental friendliness of marine structures of gas production without using flames at complete utilization of waste gas.
