The invention relates to the field of extraction of solid minerals and can be used, in particular, in the development of the fields of building materials, providing the raw material base of industrial and civil construction, for example, gravel-sand mixtures. It is also possible its use in the development of ore deposits, such as placer gold deposits. In addition, with this setup it is possible dredging in rivers and channels, including dams, for example, hydropower plants.

Known installation for underwater development of solid mineral deposits, representing a hydraulic dredge that contains the pontoon to host the soil pump, lifting means and papilioninae winches for excavation is used mounted on the frame of the suction pipe is equipped with a Ripper. Lifting and lowering of the suction pipe by using the lifting means (see Agoshkov M.I., S. Borisov and boyar V.A. Development of ore and non-metallic deposits. M.: Nedra, 1983, str-417, RIS).

The disadvantage of this setup is fixed depth of development is determined by the displacement of the pontoon, with a constant value. When the development is of mestorozhdeniy minerals, lying at great depths, it is necessary to increase the length of the suction pipe and, accordingly, its weight. To resolve the pitch, caused by changing the position of the center of gravity by raising and lowering the suction head; it is more weight, you want to increase the displacement of the pontoon.

Known floating crane, in which the elimination of the pitch of the platform caused by lifting, exercise using ballast tanks, and the rotation of the load lifted by the crane boom, produce together with the platform the pitch of which is fixed (see inventor's certificate SU # 1523536 A1, IPC4In 66 23/52, publ. 23.11.89).

The closest in technical essence and the achieved result of the claimed device is setup for underwater hydropobic minerals, including a housing made in the form of a pontoon, with posted gruntsgabalam device pivotally connected to the housing, a crane for lifting and lowering the suction head; it is, and additional pontoons mounted in the guide rails for movement along the body (see inventor's certificate SU # 1735505 A1, IPC5E 02 F 3/88, publ. 23.05.92).

The disadvantage of this setup is fixed depth of development is determined by the length of its suction head; it and displacement Pont is on. This setting is almost impossible to use in the development of mineral deposits, characterized by a variable depth within one of the extraction field.

The problem to which this invention is directed, is to increase the efficiency of ore and non-metallic deposits that lie under the waters and characterized by variable depths of productive formations.

The technical result that can be obtained by the implementation of this invention is to provide opportunities for mineral extraction at varying depths of development within the same pond installations with minimal unchanging displacement.

This technical result is achieved by the fact that in the known installation for underwater hydropobic minerals, including a housing made in the form of a pontoon, with posted gruntsgabalam device pivotally connected to the housing, a crane for lifting and lowering the suction head; it is, and additional pontoons mounted in the guide rails for movement along the body, according to the invention the housing has a U-shaped cross-section, groundsamine device made in the form of borehole hydroporinae projectile, column whose length is worth two parts, pivotally interconnected, while the plant is equipped with an additional valve for lifting and lowering of the column, and the additional pontoons are installed on both sides of the housing to align his pitch that occurs when raising and lowering the suction head; it.

This set includes all signs, each of which are necessary and together sufficient to achieve the stated technical result, in all cases, use of the invention, which is claimed scope of legal protection.

Installation for hydropobic minerals is illustrated by drawings, in which figure 1 shows the installation side, figure 2 - view of the facility from above.

Installation for hydropobic minerals consists of a housing made in the form of a U-shaped cross-section of the pontoon 1. Pontoon 1 may be made sectional, i.e. to consist of several longitudinal sections. On the pontoon 1 is the pump 2, the feed water pressure, in particular for washing mineral, with the engine 3 (electric motor or diesel engine). The motor 3 is connected to the control unit (not shown).

In the opening 4 between the longitudinal sections of the pontoon 1 is placed groundsamine device. Groundsamine device by means of the hinge 5 is connected to the housing and has the capability of raising and SDA is around Chania specified hinge 5. Thus, the hinge 5 is structurally designed so as to allow passage of the pulp to the floating pipeline 6 and the supply pressure of water, in particular, to the jetting nozzles (not shown) for washing fossil.

The hinge 5 may be placed either in the fore or aft of the hull. The drawing shows a variant of the aft location of the hinge 5. In the transport position groundsamine the device is in a horizontal position regardless of the location of the hinge 5.

Groundsamine device made in the form of borehole hydroporinae projectile, column 7 which contains the slurry line and penstock and the length is from the head 8 and rear 9 parts, interconnected by means of hinge 10. When the hinge 10, and the hinge 5, provides for the passage of pressurized water, in particular for washing minerals and the rise of the pulp.

The head part 8 borehole hydroporinae projectile has a giant monitor for erosion of minerals, and the device that provides the rise of the pulp containing protoplasmic 11. Device, ensuring the rise of the pulp, can be performed, for example, in the form of a hydraulic ejector and/or airlift. In the latter case, the installation must have a compressor to blow air and pipeline for its supply.

The tail part 9 squaring hydroporinae projectile through appropriate piping connected to the pump 2, feeding pressurized water to the jetting and hydraulic ejector, and a floating pipeline 6, which blurred minerals in the stream of pulp is fed to the plant site. To ensure the flexibility of installation connection with a floating slurry line made by the ball joint 12.

To align the trim casing installation for underwater hydropobic minerals that occur when raising and lowering the suction head; it is, on both outer sides of the body has additional pontoons 13. Each of the additional pontoons 13 can move along the Board in the guide by means of the actuator 14, for example, rack-and-pinion or troublesho. The movement of the pontoons can be both synchronous and asynchronous.

For lifting and lowering the downhole hydroporinae of the projectile in the forward and aft pontoon posted by gantry cranes 15 with the winch 16.

In the bow and stern of the pontoon installed papilioninae winch 17 to provide maneuvering installation in the pit.

Installation for hydropobic minerals operates as follows.

Gathered in the pit, previously created on the site, or delivered to waterways assembled, the unit is housed over the place, designed to draw the key. Mounted floating pipeline 6 connecting the apparatus to the shore. On the shore is mounted stationary slurry pipeline connecting the floating pipeline and storage of extracted minerals or sediments during dredging operations.

The ends of the cables papilionini winches 17 anchor on the shore. Well hydroporinae shell or head part 8 is transferred to the vertical position and start washing out of minerals. Translation downhole hydroporinae projectile in a vertical position is carried out by the initial lowering his head part 8, containing protoplasmic 11, relative to the hinge 10, located in the middle part of the column 7 by the bow or stern gantry crane depending on the location of the hinge 5 relative to the body.

Occur when lowering the head 8 of part a trim body is eliminated by moving the additional pontoons in the direction of greater precipitation. The motor control actuator movement can be carried out automatically by a signal from the sensor pitch, placed in the fore and aft parts of the hull, or directly by the operator. The operator visually determines the pitch and includes drive motors 14, providing the movement of additional pontoons to the cha the tee housing, which has a large draught. The alignment pitch that occurs when lifting the head part, is similar.

Blurred minerals enters Protopriest 11, and by means of hydraulic ejector and/or airlift rises to the surface and the slurry line is served on a construction site.
