Extraction of Fe-mn deposits from the ocean floor includes the descent of the bottom unit of nodule field collection 1, collection of sediment Fe-mn deposits in the process of moving the bottom of the unit collection nodule field 1 by towing it on the bottom of the ocean by means of a self-propelled floating platform 2. Collecting sediment Fe-mn deposits by pumping the slurry (water, sludge and Fe-mn deposits) from the surface of the bottom of the ocean bottom unit collection nodule field 1 on the flexible net capacity 3 chain conveyor 4 carried out with an average capacity of 4 m3/c. Chain conveyor 4 moves as a continuous strip and delivers nodule field on the self-propelled floating platform 2 and through the loading hopper 5 on a floating vehicle (Radovas) 6.

Self-propelled floating platform 2 provides towing the bottom of the unit collection nodule field 1 by means of a towing chain 7 and also serves as a rolling support for the chain conveyor 4.

On self-propelled floating platform 2 are controls and installation technology is practical equipment (not shown). Bottom unit collection nodule field 1 and chain conveyor mounted on the frame 8

Chain conveyor 4 is connected with self-propelled floating platform 2 lifting chains 9. Chain conveyor 4 is located relative to the floating platform 2 at an angle of 45°and to a depth of 4,5-5,5 km Length of the chain conveyor 4 is 7000 m Chain conveyor 4 along the entire length equipped with floats 10, made in the form of cylinders with a diameter of 0,72 m, a length of 2.44 m, filled with gasoline (floats with gasoline is also equipped with a towing and lifting chains). The floats 10 are fixed on the chain conveyor 4 by placing them through the floats 10 rods 11. Rod 11 is fixed every 270 see the Capacity of one of the float 10 is 887 liters. The excess buoyancy of the floats 10 makes the chain conveyor 4 weightless in the water, although the total mass of its significant (4794 t). Between every adjacent floats attached polystyrene or nylon mesh, forming a flexible mesh tank 3. The diameter of the thread, grid 5 mm cell Size 15×15 mm Mesh collected longitudinal rubber harness and when hit on her cargo stretched.

For horizontal movement of the chain conveyor 4 when it is loaded nodule field (by feeding the pulp) is installed on the intermediate sprocket 12. When loading a chain conveyor 4 speed falling stream of water mixed with ILO and Fe-mn deposits can reach up to 4.5 m/s Therefore, the chain conveyor 4 is equipped with a protection mechanism floats 10 in the feed area of the pulp on the chain conveyor 4, which is made in the form mounted on a closed circuit 13 visors 14 of the levers 15, communicates with the rods 11 of floats 10 to move the visors 14 above the floats 10. By means of these levers 15 of the rod 11 floats 10 move protective visors 14 above the floats 10, covering them at the time of passage through the flow of water with silt and nodule field.

When the circuit 13 finds on the small wheel 16, the arm 15 of the protective visor 14 is rejected and out of engagement with the rod 11 of the float 10 chain conveyor 4. The following protective visor 14 and the lever 15 picks up the rod 11 of the next float 10, etc. On a closed circuit 13 is 4 protective visor 14. The lower half of the circuit 13 is on the conveyor 17, as with the falling water on the tarp 14 circuit 13 can experience heavy loads. The roller 17 takes the load on itself.

In addition, the chain conveyor 4 is equipped with a control mechanism offload flexible mesh containers 3, made in the form of interconnected chain conveyor 4 Cam element 18, loosely mounted on the axis 19.

On bottom unit 1 is mounted to the housing of the actuator 22, re the non torque from the drive sprocket 23 chain conveyor 4 on the unit pumping slurry 21 and on tracked chassis 20 (required total estimated effort on the transport conveyor chain 85 T.S.).

Left and right undercarriage crawler chassis bottom Assembly gathering Fe-mn deposits consist of caterpillar group 24 (each of the four tracks on a common axis). Width caterpillars 1.25 m, the distance between the individual tracks of 0.5 M. the axis of the rollers 25 is rigidly attached to the frame 26. The roll diameter of 2 m, width (caterpillar) of 0.3 m Given the soft upper layer of bottom soil, the specific pressure on the ground should be small. On the one hand, the larvae do not have deep-set, on the other hand, should be a good traction with the ground. To this end between the tracks 27 tracks mounted membrane 28 rigidly connected to the plungers 29 are installed on the tracks 27 retractable spikes 30. Membrane 28 is made in the form connected with hinges and tracks 27 of the valves. The membrane 28 is considerably increases the area of contact caterpillar at ground level.

When the caterpillar is on the ground, the membrane 28 is assembled due to the fact that the track is straight. In chelsealately the design of the membrane 28 is covered soil and its pressure is additionally holds the leaf membranes in this position, and the plunger 29 is additionally presses the cleat 30 on the ground. This design caterpillars provides good traction and increasing the area of caterpillars, reducing the specific pressure on the ground. When the caterpillar finds on the rear drive sprocket 31, she sgibaete is in a semicircle, membrane 28 straightened, while the pushers 29 removing the spikes 30. The caterpillar becomes smooth. Smooth caterpillar easily cleaned by putting in place a simple scraper 32.

This site is one of the attachment points during the descent and ascent of the bottom unit collection nodule field 1. The mount led 33 to the frame 8 allows you to reject the carrier 33 in the vertical plane up to 90°. The main function of the led 33 is rotated bottom of the unit collection nodule field 1. Led 33 is interconnected with the drive crawler chassis 20 to effect the disconnection of one (left or right) suspension (caterpillar group) chassis 20 when turning the bottom of the unit collection nodule field 1.

Unit pumping pulp nodule field 21 is made in the form of a transversely located relative to the direction of movement of the two multiple-piston pump 34, mounted on both sides of the chain conveyor 4, for feeding the pulp through the suction nozzles 35 from the bottom of the ocean through the loading - transport pipe 36 in the flexible net capacity 3 chain conveyor 4.

The drive unit pumping pulp nodule field 21 is a crank. The ends of the rods are attached to the operating rod 37. To improve the stability of the operating rod 37 is supplied with voltage is aplaudida the rods 38, mounted on the bearing bushings 39. Multiple piston pumps 34 are made in the form mounted on farms 40 pipe with a diameter of 0.9 m Each pipe (pump casing) divided by partitions 41 ten sections 42 with the piston 43 from a single common working shaft 37. Each section 42 has two outlets 44, made from the side walls 41, and one input 45, mounted on an installed along the entire length of the pipe 34 of the movable plate 46. The inlet 45 of the sections 42 of the pump 34 is connected to the suction pipe 35.

In addition, the pump 34 is supplied mounted on the ends of the pipes of the pumps 34 to promote the strap 46 on the size of the inlet 45 of the sections 42 before reverse piston 43. This mechanism is in the form of a spring-loaded, interacting with the working shaft 37 and the rod 46 pivoted lever 48. When driving rod 37 rotates the lever 48, which moves the bar 46 by means of controlling the stop 49 of the strap 46. With the passage of the stem 37 of the last 5 cm, the lever 48 pushes the bar 46 on the size of the inlet. When changing direction of movement of the RAM 37, the arm 48 under the influence of prog the us 50 returns to its original position.

Thus, the inlet 45 of each section 42 is constantly accompanied by the piston 43 in this section, while during movement of the piston 43 behind him.

Suction nozzles 35 are mounted on a farm of 40 multiple-piston pump 34 and is made of pivotally United tribes, and the tribe of 51 adjacent the lap 52, connected to inlet holes 45 of the sections 42 of the pump 34, made telescopic, and the lower knee 53 suction nozzles 35 are connected with bottom suction chambers 54.

Telescopic knee 51 connected to the ball joint 55, provide rotation and sliding the suction nozzles 35 when moving the strap 46 with the inlet holes 45 to the right and left during the course of the piston 43 in the end position.

Bottom suction camera 54 Fe-mn deposits have a trough-like shape and limit water space in the lower end of the suction pipe 35. Bottom suction camera Fe-mn deposits 54 provided with side pipes to push nodule field to the suction nozzle 56, and installed in the direction 57 front and rear 58 of the supporting rollers, the front rollers 57 are made with spikes.

The width of the bottom of the chamber 54 is equal to 2.5 m, the length along the 0.5 m Benthic chamber 54 provides suction from the bottom layer of nodule field size in cross section to 15-20 cm of water and silt. The inlet is socialseo pipe 35 is extended and blocked arc (not shown), to avoid overlap of the inlet of the suction pipe 35. Through the side nozzles 56 under pressure enters the water. Water jets help to move (push) nodule field to the input apertures of the suction nozzles 35, where higher suction efficiency.

Due to the fact that the lower knee 53 pivotally mounted to rotate in a vertical plane, and the bottom chamber 54 has the ability to track the topography of the ocean floor.

Horizontal multiple piston pumps 34 keep farm 40 and ribs 59. This prevents bending and displacement of the pipes of the pumps 34 in the vertical plane. From displacement pump 34 in a horizontal plane to hold the chain stretch marks 60.

Bottom unit collection nodule field 1 has a length of 40 m, the width of the body, including caterpillars, 23 m Span multiple piston pump 34 is 75 m the mass of the bottom of the unit collection nodule field 1-900 so

Self-propelled floating platform 2 is made on the half-submerged pontoons 61 deck with the top 62 and bottom 63 decks.

On the upper deck 62 are controls, installation of technological equipment, including a motor for rotation and braking of the conveyor, the drive of the lifting and lowering of the bottom of the unit collection nodule field 1, power plant to supply power to the main engines and motors of the conveyor 4 and the grid tra is of sporter 4 (in transport position).

Lower deck 63 is made integral with the notch (15 m long, 25 m wide), on which are mounted the farm for the installation of the bottom of the unit collection nodule field 1 in the transport position of the platform 2 and to bind rugulosa 6 when operating cycle. Between the top 62 and bottom 63 decks mounted in the hopper 5 for nodule field.

Below decks (top 62 and bottom 63) are mounted lattice tank 64 to accommodate chains (7 towing to the bottom of the apparatus 1, the lifting chains 65 and chain belt, made of steel rods., in order not to accumulate water and reduce windage.

The total mass of the bottom unit collection nodule field 1 with a towing chain 7 and the conveyor 4 with gasoline for floats 10 and lifting chains 9 is 9290 so

In a separate pontoons 61 are the motors that rotate the ship's screws. The intake water is available only from the outside. Thus the screw is hidden to the flow of water caused by the thrust of the screw could not affect the chain conveyor 4. In the tank 65 pontoon 61 can be fuel for the power plant. Deck 62 and 63 are attached to the pontoons 61 cylindrical hollow struts 66, which may be located during the transportation of gasoline. Total racks 678 2 donation number m3. The total volume of gasoline 7977,5 m3. The remainder may be in separate sections of the pontoons 61. For security, free over gasoline space is pumped nitrogen, which will prevent evaporation of gasoline.

Installation for ferromanganese nodule extraction process works as follows.

In the Equatorial zone, where mainly deposits of Fe-mn deposits, in particular in the area of the Clarion-Clipperton (Pacific ocean), is a Russian plot of 150 km2provided the USSR in 1983 After selecting the production conditions nodule field (rich Deposit of not less than 5 kg/m2smooth enough the bottom of the ocean in the production area, i.e., the bottom should be passable to the bottom of the unit collection nodule field 1 and relatively calm hydrodynamic conditions in the mining area, which is characterized by the presence and speed nutricionista and surface currents) is determined by the area of the ocean for the development of nodule field.

The richest deposits are located at depths from 4 to 6 km of Such areas in the ocean are called hollows and depressions are characterized by a relatively flat bottom. High speed currents may cause harmful environmenta what I chain conveyor 4. But bottom currents have low speed (if the surface speed of 3 m/s, with increasing depth, the speed drops to 0.1-0.3 m/s). In addition, sustainable self-propelled floating platform 2 with a small windage must withstand the storms. In this zone, with a probability of 0.75 passes through at least one cyclone in the month, accompanied by storms. Therefore, an important large mass of self-propelled floating platform 2, as the platform 2 is not only tows bottom unit 1, but also rotates (moves) chain conveyor 4. A large mass even at low speeds has considerable inertia. Therefore, propulsion engines must be powerful and provide the necessary traction. Despite the large displacement, the platform 2 is unable to store the extracted Fe-mn deposits due to the large (estimated) performance installation. The discharge goes directly through the hopper 5 to Radovas 6, which also tows platform 2. Radovas 6 is located under the platform 2 between the posts 66. Radovas 6, while under load, not scrolls their screws so as not to have jets impact on the conveyor 4. Power source electricity consumers on the platform must be powerful power plant 45-50 MW (thermal power plant for liquid fuel - oil, diesel, gas turbine power plant gas condensate, atomic m is neither a power station as for the EPL) and the storage tank for liquid fuel, or deployment of nuclear power plants.

When immersing the bottom of the unit 1 on the bottom of the ocean mounting the chain conveyor 4. Mounted and refuel gasoline floats 10. Between the floats 10 are attached to the mesh flexible containers 3 for Fe-mn deposits. The process of lowering the bottom of the unit collection nodule field 1 laborious and time consuming. First bottom unit collection nodule field 1 is lowered vertically, but on reaching the bottom of the unit collection nodule field 1 of the bottom of the ocean platform 2 gradually moves up until the whole chain conveyor 4 will not be mounted. When lifting the entire process takes place in reverse order.

One net capacity of 3 chain conveyor 4 in the middle can get up to 233 kg nodule field, but given the Archimedean force it will be 155 kg, which will determine the force of gravity. Net capacity 3 assembled on the rubber harness. When the cargo net capacity 3 mesh stretched. Chain conveyor 4 is tilted at an angle of 45° to the level of the ocean. Cargo delays the net capacity of 3 and creates a wing. In addition, when the tension of the grid cell is collected in a dense set of nylon threads. It turns out the wing at an angle of up to 10-12° with respect to the velocity vector of the chain conveyor 4 relative to the bottom of the unit collection nodule field 1.

The force with which the actuator on the platform 2 tanetane conveyor 4, smooth 1120 TC. The frequency of rotation of the drive sprocket 23 chain conveyor 4, installed on the bottom unit 1 flat 15 rpm Linear speed of the chain conveyor 2.35 m/S.

Transport chain chain conveyor 4 report leading asterisks 23 chain conveyor 4, the force is distributed between the three consumers: by the chain conveyor 4, the pumping unit and feeding the pulp 21 on the chain conveyor 4, the rotation of the leading stars tracked chassis 20. Possible deviation of the chain conveyor in the horizontal plane up to 10°.

Bottom unit collection nodule field 1 will always move to where directed spring-loaded carrier 33. In the event of a change rate of the platform 2 or rejection of the bottom unit collection nodule field 1, is the deviation of the carrier 33 of the longitudinal axis of symmetry of the bottom unit collection nodule field 1. The mechanism of reversal must respond when the deviation of the carrier 33 of the longitudinal axis of the bottom of the unit collection nodule field 1 2°. The mechanism of the clutch-brake (not shown) of the group of tracks 24, in the direction which is inclined carrier 33 will stop this group of caterpillars. The opposite group of caterpillars remains fluid. Rotation is carried out bottom of unit collection nodule field 1.

Then drove 33 again becomes in line with the axis of symmetry of the bottom unit collection nodule field 1, and through the mechanism scaleni the-trip will move previously stopped a group of caterpillars. In the General case, the reversal will be done automatically.

The speed of extraction of the lifting and towing chains of 0.5 m/s braking System is used during the descent and ascent of the unit collection nodule field 1 and the chain conveyor 4.

Work multiple piston pump 34 is as follows. The piston 43 of each section 42 is located between the lugs 47.

When the piston 43 in each section 42 in one direction or another, he (the piston 43) acting on the lugs 47 of the strap 46, (all ten of the pistons 43 all ten sections 42 are at the same time) starts to move very bar 46 with the inlet holes 45 a. And the inlet 45 of the section 42 is always behind the piston 43. Simultaneously with the strap 46 begin to move, turning and radvilas, suction nozzles 35. As the piston 43 is formed a zone of reduced pressure, and the water pressure in the suction pipe 35 is higher than the pressure in tapartnews area, water from the inlet tube 35 is directed in the area of the section 42.

Through the outlet 44 a mixture of water, sludge and nodule field is pushed out through the output pipe 68 of the pump 34 in cargo transport tube 36. Square in cross-section cargo transport pipe 36 gradually increases toward the exit. And outlet pipe 36 has an area equal to the sum of the squares of ten vyhodnyeb 67 of the pump 34. The rate of flow of slurry equal to 4.5 m/s In the output pipe 67 has a valve 68, which is working on the release of water from two adjacent sections 42. One cargo transport pipe 36 (one multiple-piston pump 34) follows 2 m3/s. The threads of the two cargo transport pipe 36 from each pump 34) separated. The chain conveyor 4 is served General flow of 4 m3/s. For the full stroke of the pistons 43 (2 m) chain conveyor 4 drops 24 m3/sec for 6 sec. Both stroke of the piston 43 are working.

The diameter of the leading stars of the caterpillar group 24 is equal to 1 m speed of asterisks equal to 9 rpm Speed of the bottom unit 1 will be equal to 1 knot (0.5 m/s). During this time one suction nozzle 35 must, on average, involve 0.2 m3/c water from under the bottom of the suction camera 54. The percentage of collection of nodule field with 1 m2will be high (up to 67%)

All the pipes through which is pumped a mixture of water, silt, and Fe-mn deposits should be made of stainless steel of high hardness, for example, of steel 30 chorionic gonadotropin, which HB-415. Farm, stiffeners, brackets for mounting the fixed portion of the suction nozzles can be made of steel HT, which HB-360. Wheel gear, crank, rods, chains must be made of highly durable steel. The tray 69 for removal of turbid water, passed through the mesh conveyor 4, which should be made of solid steel. The increased hardness of the tubes is necessary in order to avoid scratches on the inner surface of the pipe, which increases the resistance of the flow of pulp.

Caterpillars can be made of titanium alloys to facilitate the entire unit. Specific pressure such caterpillars (with a total unit weight of about 900 tons) would be about 130 g/cm2. The engines on the platform must be DC power up to 10 mW, with an excitation winding connected in parallel with the armature winding.
