Description
Technical field
The utility model relates to oceanic mineral resources Mining Equipment field, is specially a kind of oceanic mineral resources quarrying apparatus, for gathering abyssal floor mineral, and marine mineral is delivered on water surface mining dredger.
Technical background
Oceanic mineral resources is exploited as the most promising new industry of 21 century, for generally paying attention to countries in the world.The abundant metallic mineral resources such as manganese nodule, cobalt bearing crust, hydrothermal solution sulfide, multimetal mud are being contained in the international sea-bed area that accounts for earth surface 49%, it is the maximum potential strategic resource base of not yet being fully realized and utilizing by the mankind on the earth, its exploitation method causes that various countries pay much attention to and very big research enthusiasm, carried out at present continuous line bucket mining system both at home and abroad, shuttle back and forth mining vehicle mining system, undersea mining car adds the research and development of three kinds of mining methods of Pipeline lift mining system automatically.
The principle of continuous line bucket mining system is every a chain bucket of 25 to 50 meters of hangings on a cables, the cable guide wheel of installing by (double-boat type) on mining dredger bow and stern (single boat form) or two ships forms electrodeless cycle operation, chain bucket scoops up tuberculosis rise to sea from seabed, its advantage be system equipment simple, easy to maintenance, invest little, but exist mining efficiency and resource recovery low, require the problems such as sea-floor relief is smooth, the easy winding of hawser.
Automatically shuttle back and forth the mining vehicle of mining vehicle mining system by own wt and ballast dive, ballast leaves in tuberculosis storage cabin, when mining vehicle arrives behind seabed, mining vehicle utilizes Archimedian screw propeller to walk in seabed, discharge ballast while gather the tuberculosis of equivalent weight, when last piece ballast is discharged from, when tuberculosis is filled in storage cabin, mining finishes, mining vehicle returns to sea and enters semi-submersible type underwater platform and unload ore deposit under the angle of rake promotion of snorkeling, then again load onto ballast and slip into down again seabed, circulation realizes the exploitation of seabed tuberculosis and so forth, its advantage is that equipment is independent, flexibility is good, single device fault is little on mining system impact, shortcoming is that the operation of mining process discontinuity, snorkeling non-cutting time is long, single machine production power is low, needs high performance battery, need to use ballast replacive concretion, and mining vehicle manufacturing process and telecontrol engineering requirement are high, involve great expense.
Undersea mining car add pipeline hydraulic promote mining system by mainly by undersea mining car, middle cabin and by riser tubing with promote the hydraulic hoisting system that electric pump forms and form, the seabed ore that mining vehicle gathers, ore is risen to water surface mining dredger from seabed by promoting electric pump by riser tubing, in this mining system, undersea mining car is divided into again submarine formula mining vehicle and seabed self-propelled mining vehicle.Submarine formula mining vehicle generally adopts skateboard, pull and slide in seabed by ore-raising pipe road by water surface mining dredger, have simple in structure and good anti-settling ability, but do not avoid submarine obstacle and control its slippage gathering the ability of route, undersea mining efficiency is low.
Because the supporting capacity of bottom sediment is low, the walking mechanism of seabed self-propelled mining vehicle mainly contains involute grouser rubber caterpillar type walking mechanism and spiral of Archimedes walking mechanism at present.Because sea-bottom deposit water content of matter is high, very soft, for reducing the grounding pressure of collecting machine, crawler type walking mechanism must select wider crawler belt that enough support forces are provided, experimental study both domestic and external all shows, crawler-type traveling collecting machine exists and skids, turning radius is large, depression is serious, even falls into extremely in deposit, occurs being uncontrollablely arranged on mining mechanism on mining vehicle and greatly reducing the collecting efficiency of mining mechanism from the problem of end height simultaneously.Although spiral of Archimedes walking mechanism smooth running, but still exist turning radius greatly, easily to skid and the shortcoming large to seabed disturbance.Therefore the seabed self-propelled mining vehicle of existing development is not all resolved the problem of seabed walking mechanism.
