The invention relates to shipbuilding and the construction of specialized vessels for production and transportation of ice of the Arctic and Antarctic icebergs.

Known vessel for development and transportation of ice icebergs containing the main unit with energy is a, and a few Rethimno connecting sections (magazine Shipbuilding abroad", Leningrad Shipbuilding, N 5 (77), 1973, S. 75-76).

However, such a vessel is difficult mooring to the iceberg and narrowed the range of operation of marine complex for development and transportation of ice.

The technical result from implementation of the invention is to facilitate the mooring of the vessel to the iceberg and the expansion of the range of operation of marine complex for development and transportation of ice.

The technical result is achieved by the fact that the ship is for the development and transportation of ice icebergs contains the main unit with power plant, propellers, anchor, mooring devices, control systems, crew accommodation and several Rethimno connecting sections, the above-mentioned sections are equipped with cargo tanks, pipelines with the actuator and valve for the transfer of melt water coastal consumers thruster devices and devices for mooring of these sections to the iceberg, as well as devices for crushing ice and loading it in tanks mounted on each section or on one of them, each device for mooring to the iceberg made in the form of viaviente the angle of the rod relative to the rack and drive its extension-retraction, while holding the cylinder is made of not less than two lobes with outer cutting edge connected with the mechanism for changing the angle of their installation relative to the longitudinal axis of the rod, is installed with the possibility of rotation relative to the axis and connected to the rotational drive.

In addition, a sliding rod mounted on the rack so that they can move their connecting hinge along the rack on rails.

In addition, the retractable rod is made telescopic and is connected to the hydraulic drive its extension installed on the vessel.

In addition, the length of the rack rails not less than the difference of the calculated sediment vessel fully loaded and empty.

In addition, the rear portion of the holding head is connected with an electric motor mounted in the head portion of the sliding rod.

In addition, the drive rotation of the holding head is made in the form of a shaft installed inside the sliding rod and connected with the mechanism of its rotation.

In addition, the mechanism changes the angle of the petals holding head is made in the form of a cylinder.

In addition, under the outer surface of the holding head is placed heating element is avishay the cross-sectional area deepens part of the sliding rod.

In addition, the retractable rod is equipped with a mechanism for its rapid dissociation, made mostly in the form of cutter.

In Fig. 1 shows a diagram of powertogo longitudinal placement section on the main unit of the vessel; Fig. 2 is the same, with the transverse placement of the partitions on the main unit of the vessel; Fig.3 a device for mooring to the iceberg; Fig. 4 scheme of holding the head of this device.

The vessel (Fig. 1 and 2) contains a main unit 1 and a few Rethimno connecting sections 2. You can perform a basic block in the form of a longitudinal frame and powertogo connection with him cargo sections (Fig.1) or their serial connection (Fig.2). On each section or one with a device 3 for development (crushing) of the ice of the iceberg.

The vessel is equipped with propulsion plant, ship systems, propulsion control systems, crew accommodation and devices for docking and detachable connection sections (not shown), as well as devices for mooring to a monolithic ice (Fig.3).

Section vessel equipped not shown in the drawings, the cargo tanks, pipelines with the actuator and valve for transferring melt in the and, mounted on each section or on one of them.

Each device for mooring to ice contains retractable, mainly telescopic rod 4 with the damper 5, is fixed by means of the hinge 6 on the rack 7. Between the rack and barbell set the actuator 8, mostly hydraulic, change the installation angle of the rod. Rod connected with located on the vessel drive her nomination, mainly hydraulic (not shown). Hour contains guides 9, which moves freely on the rollers 10 node swivel bar from the rack. You can also move a node and using the sliding surfaces. Hour 7 installed on the deck or in side niche of the vessel.At the end of the rod set holding head 11, the front part of which is made in the form of at least 2 petals 12 with the outer cutting edge 13. The head 11 (Fig.4) is connected with the mechanism of its rotation, which can be used motor 14 both normal and reversed type or shaft (not shown) passing inside the rod and coupled with a drive of its rotation. The petals are pivotally connected with the rear part of the head, and with the rods 15 of the power mechanism 16, p in order to accommodate the heating elements 17, and on the surface of the head of the screw lugs 18 to remove ice chips. The cylinders are connected by pipes with a source of high pressure working environment, and the motors and heating elements with a source of current, available on the ship.

The device operates as follows.

At the approach of a vessel to the area of production of ice cargo section 2 are detached from the main unit 1, suitable to the selected iceberg, moored to it, loads of crushed ice when the operation of the unit 3, and then come together in a single ship complex, next to the port of destination. You can install location 3 on all partitions, and one partition. In the latter case, it provides the ability to download both their own and other sections. This increases the load time, or require the installation of higher productivity, but reduces the number of units 3 and devices for mooring to the iceberg, as pure transport section moored to the section installation 3.

At the approach section to the iceberg rod 4 extends to the contact holding head 11 with ice. By means of the actuator 8, the rod is set at the required angle to the surface of the ice. During the rotation Quemoy length (pre-5-7 m). Constant preload of the vessel to the iceberg at this time is provided, for example, thruster. To compensate for the effort with a sharp naval vessel on the iceberg, for example, when excited, the rod contains the absorber 5.

After the desired penetration rod petals 12 head through the rod 15 of the hydraulic cylinder 16 is removed from the axis of the head at the angle of 30-70o. If this continues the rotation of the head and the sampling holes in the ice correspondingly larger diameter. After the termination of the rotation allotted petals prevent the output rod of ice masses which provides mooring of the vessel.

To avoid damage to the rod with the vertical movement of the vessel is provided free vertical movement of the node swivel mount 6 rod along the guide rails 9 hours 7 on the rollers 10. The node can also be done in the form of a carriage with sliding surfaces which are in contact with the guides. The length of the rails must not exceed the difference between the residue of the ship in the cargo and empty, and the possible magnitude of heave. Provides rapid disaster impact arm holding the head with the extreme situation using prodatron.

To remove the knife is Cai. In addition, on its surface can be made of screw lugs 18.

To return to the moorings head is driven, the hydraulic actuator 16 causes the petals 12 to its original position, and the rod of the actuator extension is extended from the channel in the ice. To reduce the time of getting away when freezing petals to ice the head heats the heating elements 17, which can also be used when the depth of the rod in the ice.

The equipment of the ship a device for mooring to a monolithic ice allows reliable mooring to any ice massifs, including steep slopes, while the efficiency of the device is provided with excitement and change the precipitation vessel. Thus, this invention allows you to create a transport system for the delivery of ice icebergs in the areas, which need fresh water, and clean drinking water to the population of developed countries.
