Sea mining production package and procedure for its operation and transport conditions
SUBSTANCE: invention refers to mining and can be implemented at complex industrial development of mineral resources of world ocean. The package consists of a transport floating sea-based station in kind of a semi-submersible floating platform with an underwater hydraulic support-container. On the platform there is made a through vertical shaft and above-surface decks. The following is arranged on the station: a hydraulically hoisted installation consisting of a hoisted pipeline of interconnected pipes installed in the shaft of the hydraulic support-container. In its upper part the pipeline communicates with an unloading hopper and with a receiving chamber also connected with a cavity of the hydraulic support-container by means of the pipeline. In its lower part the pipeline is coupled with a collector. The installation also consists of an evaporating system connected to a condenser via a steam line and to the unloading hopper via an evacuating pipeline. The evaporating system is equipped with a heating battery and a brine chamber coupled with the unloading hopper by means of the pipeline. Further, the installation consists of a thermo-siphon of a nuclear plant connected with the heating battery of the evaporating system through the steam line. The thermo-siphon is connected with its own condenser by means of the steam line and pressure line. The condenser of the thermo-siphon is installed under the condenser of the evaporating system and coupled with the latter by means of a down-take pipeline. Also the installation consists of bottom excavating devices tied with the collector of the hoisted pipeline by means of slurry lines. The novelty of the invention is like follows: additional through shafts are made in the hydraulic support container. The additional shafts have inter-shaft through slit apertures communicating the additional shafts and the shaft of the hoisted pipeline. Also there are the thermo-siphon of the nuclear plant and bottom excavating devices installed in these shafts. Under water the excavating devices automatically retract from the shafts and enter into them together with connected pipelines, steam lines, slurry lines and other communications freely arranged in the inter-shaft through slit apertures. Notably, to eliminate clogging, equipped with valves branches of blow-off main are connected to hinged facilities. Novelty of the procedure of package operation and transport condition consists in retracting equipment, including the hoisted pipeline, from the shafts and under water lowering, in hoisting it back and receiving it into shafts together with communications coupled and connected to equipment. Thus, submerged floating stations are attributed with controlled, correspondingly, negative or positive buoyancy.
EFFECT: raised efficiency and reliability of package operation due to reduced time and labour for lowering-hoisting operations and due to eliminating assembly and disassembly operations at excavating site.

The invention relates to mining (mining and marine) industry concerns floating marine mining, containing as an energy source marine nuclear power plant (APEC) and engaged in one with it technological production cycle production at the bottom of the sea and rise to the surface of minerals, their processing with the output of marketable products, and recycling of the sea water to obtain fresh water and various nutrients, and can find application in complex industrial mineral resources of the World ocean.
The most effective use of the invention under conditions year-round Autonomous operation in the open sea with deep sea mining on the seabed polymetallic ores, mainly ferromanganese nodules (nodule field) with their complex processing to produce a marketable product (Nickel, cobalt, copper, manganese, and others), with simultaneous desalination and recycling of the brine with the release of a variety of nutrients (mineral salts, bromine, iodine, magnesium, lithium, deuterium, and so on).
The known method of hydraulic lift placer solid minerals from the seabed to the surface through the creation of the lifting pipe pressure drop transporting water by its IP the e at the top of the discharge part and performing its hydrodyna installation, operating in conjunction with naval nuclear power plant (APEC) /1/.
The closest to the invention and employees subject to further improvement and development is known, using /1/ floating sea-mining-industrial complex engaged in a single technological cycle in process heat and electrical energy to the included marine APEC deep seabed mining on the seabed and the rise of the craft-based nodule field with simultaneous desalination of sea and receiving fresh water and concentrated brine for further processing /2/.
Complex-prototype includes transport floating home in the form of a semi-submersible floating platform with underwater hydro bearing container with made it through by a vertical shaft and mounted on support surface of the deck and placed it: hydropolymer installation containing specified in this mine consists of interconnected pipes lifting the pipeline, reported in the upper part of the discharge hopper and the associated pipeline cavity gidropony container receiving chamber, and at the bottom - with header-drive, and connected by piping to the discharge hopper and the steam line to the condenser evaporation plant with the heating battery and Rasso Inoi camera, connected by pipeline with the discharge hopper, thermosyphon marine APEC associated steam line to the heat battery of the evaporator unit and discharge the steam line and pressure pipe from the condenser and the bottom of a producing apparatus connected by pipeline with the collector-drive lifting of the pipeline.
Bringing complex prototype in an operational state, in which the descent and underwater installation at the place of production of the above equipment and connecting utilities (pipelines, steam pipelines, coal slurry pipelines as well as power and control cables and other connections) to perform the necessary underwater precast erection works, including a connection (screwing) pipe (pipe sections) lifting of the pipeline with the formation of the tubular rod and the latest in underwater working position, as well as bringing complex prototype in the transportable state when the change of the mining area, which consists in carrying out the folding and dismantling, including disassembly of pipe rod on a separate pipe (pipe section), and the lifting of all equipment and connecting communications back to the craft-based, manufactured by known methods and with known technical means, since the construction of the complex in General and the design of his recovery is tion of the pipeline are not adapted for use otherwise.
So, you know bringing the lifting of the pipeline in its working position, when the precast erection and standpipe work is performed using the set above is made in the vessel drain well derrick-crane (height of 66 m) and other traction mechanisms (/3/, p.75-77, RES, 52).
In another known embodiment, to bring hydropathies installation in working condition pipe section and the lifting pipe equipped with floats and ballast tanks and afloat in a horizontal position sbencivu with each other with education (km) floating pipe structure, which is then released from the floats and filling the ballast tanks are transferred from the horizontal in the working underwater vertical position (/4/, str, str-280, 2, 3).
Casting installation in the transportable state when the change of the mining area includes the transfer of the tubular rod of the underwater vertical back floating in a horizontal position (by blowing ballast tanks and the suspension floats), disassembly on a separate pipe (pipe section), dismantling and loading to the vessel.
A disadvantage of the known and used in the complex-prototype ways to bring it in working and transported condition is a necessity when conducting round-trip on the of eraci perform highly complex, time-consuming, requiring considerable time and, however, do not provide good quality, is not always possible and far
unsafe in the open sea collapsible construction and dismantling of underwater works, which significantly reduces the efficiency and reliability of an industrial complex.
To improve the efficiency and reliability of the Complex due to the acceleration by reducing the complexity of bringing it into working and transported condition by reducing time and reduce labor costs to perform tripping excluding underwater precast erection and folding dismantling at the extraction site and we offer this invention.
This objective is achieved in that the bearing container made additional end-to-end of a vertical shaft with informing them among themselves and with the mine hoisting pipeline through Mezhdurechye slotted openings, evaporative installation, thermosyphon APEC and bottom producing the devices are installed in these mines with the possibility of automatic submarine out of them and back entrance to them together with a binder and constantly connected pipelines, steam pipelines, coal slurry pipelines and other communications shall, which are freely available on Midosuji through the slot openings.
Thus to simplify by reducing the effort of holding tripping lifting the pipe from the discharge hopper, a receiving chamber and a collector-storage, evaporation plant, and the bottom producing the devices are installed in the mines gidropony container afloat to separate from her underwater craft with adjustable buoyancy with automatic exit from the mines when submerged vessels and reverse the underwater entrance to the mine when the last ascent together with a binder of their pipelines, steam pipelines, coal slurry pipelines and other communications.
In the open sea underwater reception of vessels considered to be the safest, and the technique and technology of its realization is known (see, for example, /5/).
For this and for the same purpose of lifting the pipeline is made consisting of movably connected to each other through a hollow hinge devices of the pipe (pipe sections), folded with the formation of tubular batteries, and installed with a discharge hopper, a receiving chamber and a collector-drive in mine gidropony container on the underwater craft with adjustable buoyancy with the possibility of unfolding of the battery in the tube becoming immersion PL is in and folding pipe stand pipe in the battery, with the entrance to the mine during the ascent of the latter.
For this purpose, the hinge device is made consisting of the United hermetically and movably with the possibility of mutual limited 180 degrees of rotation relative to each other of the coupling halves, each of which sequentially attached to the ends of the adjacent pipe.
To eliminate the possibility of clogging of pipes pulp to the hinge device, in particular to the coupling halves, which are attached to adjacent pipes, additionally attached is provided with automatic valves piping purge line.
Folding in the battery design eliminates the occurrence in the tube rod dangerous bending stresses, and also gives the possibility of regulation in the production depths.
It is known to reduce bending stresses in the upper part, where they are maximum, attach the lifting pipe to surface craft using a hollow ball joint that allows the tube to the rod under the action of lateral loads to deviate and reduce stress (/3/, p.75-77). But this does not exclude the occurrence of a hazardous voltages in other parts of the structure.
It is also known the use to reduce bending stresses in the connection of pipe sections by means of flexible elements /6/. However, the tube sections have a very limited the military mutual mobility, can't be folded compactly in tubular battery, and do not give the possibility to regulate the depth of mining.
The described way of bringing the Complex into a working state in which the output of the mines with Mezhdurechye slotted openings of gidropony container and submerged descent to the working depth set them on underwater craft equipment, namely, tubular battery lifting of the pipeline with the receiving chamber, a discharge hopper and reservoir-accumulator, evaporator unit with the heating battery and brine camera and seabed mining machines, as well as connecting their utilities (pipelines, steam pipelines, coal slurry pipelines and others), is that the output from the mines and underwater descent equipment is produced together with a binder and attached flexible communications and implemented by giving underwater craft adjustable negative buoyancy. When first removed from the mines and produce joint controlled by the position of communications underwater descent tubular battery with the receiving chamber, a discharge hopper and reservoir-drive lifting of the pipeline followed after landing an inlet chamber at the working place in the bearing container by folding tubular battery in the tube becoming and the evaporator unit is connected the output to the upper end of connecting it to the condenser primary hard (fixed) steam more flexible steam line extension, and as lowering the collector-drive lifting pipe is removed from the mines and descend to the bottom of a producing apparatus.
A method of reduction of the Complex is transported in a state in which the lift-off technique in mines with Mezhdurechye slotted openings of gidropony container is installed on the watercraft equipment: tubular rod lifting of the pipeline with the receiving chamber, a discharge hopper and reservoir-accumulator, evaporator unit with the heating battery and brine camera and seabed mining machines, as well as connecting their utilities (pipelines, steam pipelines, coal slurry pipelines and others), is that lifting equipment is produced together with a binder and attached flexible communications and implemented by giving underwater craft adjustable positive buoyancy when first produced joint controlled by the position of communications rise with folding tubular battery tubular rod with a discharge hopper and reservoir-drive lifting pipe, the evaporator unit and the bottom of the extractive apparatus, after which together with the latter produce lift tubular battery with a receiving cell and their reception in mine gidropony container with dressing binder communications in Mezhdurechye slotted roomy and connect a hard core (fixed) steam evaporator unit to its condenser.

SUBSTANCE: invention refers to hydro-mechanised complexes for extracting concretions from sea bottom. The complex for extraction of concretions consists of a base vessel, of a pulp pump with suction and outlet branches, of a pressure pipeline connected with the outlet and suction branches by means of flanges, and of a perforated branch with dimension of holes equal to a minimal size of extracted concretions. Also the pressure pipeline is directed vertically, while its above water part is pivotally secured on the end of a derricking jib of a swing crane by means of a sleeve; the swing crane is arranged on the base vessel and is designed to lift and lower the pressure pipeline and also to transfer it in horizontal plane. The upper part of the pipe line is connected to a concretion receiving capacity by means of a flexible hose. Four pontoons of a cylinder shape are arranged on the middle part of the pipeline symmetrically relative to its lengthwise axis and along it; the pontoons are designed to be filled with water and to be blown off with compressed air. Also the pontoons are arranged on the pipeline between the flanges secured on the latter; the pontoons are connected between them and pressed to the pipeline by means of flexible bands. Cantilever swinging framework kinematically tied to its swing drive is assembled on the lower section of the pipeline; this framework is designed to rotate relative to the pipeline in horizontal plane. Two blades symmetrically located relative to the suction branch are secured to the framework from below; the blades rest on the water area bottom, grab concretions and transfer concretions to the suction branch. Notably, each of blades is made with a horizontal lower edge in cross section; an inclined part of the blade adjoins the lower edge and forms an acute angle, the vertex of which is directed to the side of blade motion; an upper horizontal edge adjoins the inclined part and is connected to it with a curvilinear section. Value of acute angle is accepted less, than the angle of friction in pair of concretion with host rock that is internal surface of the lower edge and the inclined part. In plane view each blade is profiled along logarithmic spiral with a pole coinciding with the axis of the suction branch; the external relative to the suction branch edge of the blade and its lower edge are bent to the direction of framework swing, while the blade adjoins the suction branch with a minimal circular gap in plane view. The suction branch is made in form of a truncated cone expanding downward. The concretion receiving capacity is made in form of an inclined sieve grate, wherefrom dehydrated concretions are reloaded into movable containers; a sump is assembled under the sieve grate.
