Definitions

  • the application relates to a device suspended on ropes and "floating" above the seabed, which allows large amounts of manganese nodules to be mechanically cleared from the seabed and lifted up into a conveyor pipe system without detecting other sediments from the seabed.
  • a device suspended on ropes and "floating" above the seabed which allows large amounts of manganese nodules to be mechanically cleared from the seabed and lifted up into a conveyor pipe system without detecting other sediments from the seabed.
  • vertical telescopic conveyor tube lengths have been used, so that no additional tube assemblies are necessary after the conveyor systems for a known area, e.g. in the calm ocean.
  • the underwater roller rakes with tower which hereby apply for a patent, not only avoid the installation or operation of energy generators that are too large, and thus a poorer overall efficiency of the large systems, they also exercise a controlling function after the mechanical elevation of the manganese from the sea floor that is now possible using roller rakes and sorting slots sorting function.
  • This not only prevents sea water pollution, it also keeps the energy-consuming friction conditions in the very long main delivery pipe more uniform and lower, and prevents disruptive influences during delivery within the pipes and compensating pipe parts with fittings. The total energy expenditure can thereby be kept lower, so that better economy is achieved with the same delivery rate. This is also supported by the restraint of the "chunks" that are too large to be subsidized and by avoiding the sediments that are also conveyed, which only burden the subsidy.
  • the "propulsion speed" of the mother ship on the sea surface is dependent on the time it takes to move the clearing device back and forth on the sea floor.
  • the clearing direction of the equipment moving on the seabed is always perpendicular (transverse) to the direction of travel of the mother ship. Therefore, a "zigzag line” is created on the seabed, which means that the speed of the mother ship is dependent and limited.
  • roller computing system with tower takes these new findings into account by keeping the direction of propulsion of the mother ship on the surface of the sea aligned with that of the systems operating on the sea floor. This eliminates the dependency on the clearing width on the sea floor and the time for a back and forth movement of the clearing devices.
  • erfindungsgemäi j is the telescoping of a conveyor pipe according to the selected anticipated height differences in the range of a contemplated Abhoffm capablees or decorated. Accordingly, 1000 to 2000 meters and more height differences (e.g. in the still ocean) can be overcome without having to install or remove pipes on the sea surface. This eliminates the usual downtimes in clearing the tubers and also significantly improves the company's profitability.
  • the underwater roller rakes Fig. 1 (26) with a tower-like lattice construction Fig. 1 sheet 1 and sheet 2 (3, 5, 17, 18, 19) consist of cylinder-like round bodies rotating on hollow shafts, which are attached to the lattice construction, at the top inner hollow shafts provided with larger openings are movably mounted.
  • the spoke walls which are connected to one another by means of web plates, are attached to the outer hollow shafts rotating on the “fixed” inner hollow shafts with upper openings and provided with slots and acting as hubs.
  • Fig. 9, 10, 11 At the outer ends of the spoke walls, the rake plates combined in "packages" are fastened with claws.
  • the spoke walls consist of profiled slotted sheets with internal reinforcing webs.
  • All spoke walls are given angularly curved sorting plates on the opposite sides along the entire length of the roller rakes, with their opposing reinforced edges Fig. 9 (39) an inclined from top to bottom inward, from the outer end of the roller rake towards the inner end , gradually forming sorting slit.
  • the opposite spoke wall surfaces on the hollow shaft hub with slots receive hard metal reinforcements Fig. 9 (40).
  • the outer spoke walls are preferably provided with hinged two-part movable buckets or shovels which have side walls on both sides to limit them. These buckets are somewhat radially inward and circularly movable due to slot slots and bolts. Fig. 10.
  • the granular or stone-like tuber material which is lifted in a circle from the sea floor with rake packages and claws or with buckets, reaches the upper "position" of the culmination point when the roller rakes are first driven or forced by cable drives from the mother ship, and then in by the drag force of the water and gravity the outer slits of itself rotating hollow shaft and then to flow through the larger only upper openings of the non-rotating inner hollow shaft into the interior thereof and then into the delivery cylinder or into the actual delivery pipe. 8, 9, 10, 11.
  • the weight of the underwater roller rake is determined by a tower-like lattice construction tapering from bottom to top, which is shown in FIG. 1 (17, 18, 19), which is attached to steel cables Fig. 1 (6) via spring-mounted Fig. 6 (43) rope pulleys Fig. 1 (24) hangs, worn.
  • the ring ship as the mother ship carries the entire construction in a known manner and keeps it floating during the clearing process at the necessary height above the sea floor.
  • the "immersion depth" of the computation packages with claws in the sediment layer of the sea floor bearing the manganese nodules is guaranteed or co-controlled by the controlling and delimiting at least two large wheels Fig. 1 (27), the hollow shafts of which are also mounted on springs. Due to the possibility of the large wheels (27) evading upwards to a limited extent, a temporary, damping, soft impact of the roller rakes with their tower-like structure made of grid construction on the sea floor is harmless.
  • the elastic expansion compensators, ball sockets and stuffing boxes located inside the tubular body facilitate this low mobility and thus avoid undesirable loads and harmful tensions in the material of these elements.
  • the underwater roller rakes are initially driven by means of ropes driven from the supporting ring ship via rope drums arranged on the same hollow shaft with the roller rakes. The same are mounted in such a way that clearing the entire area without leaving undetected gaps on the sea floor is possible and secured, FIGS. 5, 7.
  • the initially selected outer drives of the outer roller rakes are e.g. around sprockets with link chains, Fig. 7.
  • Gears and motors with worms and worm gears are later planned.
  • the side elevation Fig. 6 shows one of these tower-like structures with perforated fenders on the floor and safety bumpers.
  • the self-evident additional devices such as headlights, television camera, sensors, solders, pressure gauges are installed on the bumpers Fig. 6 (42) and attached to the bottom.
  • the invention therefore also aims at overcoming or avoiding subsequent assembly work, which means downtime after the conveyor system once, e.g. was set up and made operational for conditions in the calm ocean.
  • the tower height is therefore e.g. about 1000 to 1200 meters and the total height of the feed cylinder can be 1000 to 2000 meters. In order to be able to use these heights in a stable and kink-free manner, additional stabilizing agents are required.
  • the total "section modulus" of tower extension, delivery cylinder 2 and delivery pipe 1 Fig. 1 is significantly increased by additionally providing, for example, from 200 to 200 meters (vertical) stabilization levels in a self-floating, weightless property or centrally, for example, around doors and delivery pipe be arranged around.
  • the existing suspension ropes which act like steel rods when loaded vertically by the tower and the feed cylinder, are used sensibly.
  • These four to eight vertically hanging steel cables can therefore be used without additional stress for the the same a lateral supporting or guiding or guiding function for the whole roller computing system with tower can be expected.
  • the buckling or the tendency to this is completely avoided by means of such horizontally acting stabilization levels.
  • Fig. 2 shows the floor plan of such a stabilization level.
  • the same is made of plastic pipes, for example polyethylene.
  • the tubes are provided with strong ridges horizontally arranged on both sides and vertical double ridges on the inside for reinforcement and to compensate for the buoyancy of the rope pulleys with their trestles acting on the outer ends attached band springs Fig. 3 (38).
  • a slight permissible horizontal deflection or movement of the vertical elements to be protected is possible, a harmful one, the material highly stressful bending or kinking are excluded.
  • the cross sections of the polyethylene pipes with horizontal and vertical webs are illustrated in FIG. 4.
  • Fig. 1 sheet 2 (11).
  • roller rakes hanging at the bottom of the lattice structure will lag somewhat behind the "position" of the supporting ring ship after the start of production due to the resistance of the roller rakes "immersed” in the sediment of the sea floor, which tuber-lifting in the upper sediment.
  • the vertical "position” of tower and conveyor cylinder with conveyor tube is then ensured by the individually operated large mining winches in the ring ship.
  • the uneven lagging of the roller rakes which is possible due to unilaterally different resistances on the seabed can be somewhat compensated for by unilaterally lifting such a lagging side which is more than desired or permissible. Because of "lost time” and the harmful economy Lichen effects, however, according to the invention, the engagement of the proposed horizontal engines (35) Fig.
