Abstract
A refloatation device is composed by a grab, an outstretching riser linked to the grab through an effuser and a pump linked the grab through a water pipe and the power. The device uses seawater as carrier and is capable of grab a stuff of density 7.9g/cm3 from 3400 meters benthal and horizontally eject out 3 meters above sea.
Description
Technical field
The present invention relates to a kind of underwater operation equipment, particularly seabed fetching device.It can from the seabed extraction of substance of 3400m depths (proportion 7.9 grammes per square metres/centimetre
3).
Background technology
It is that scientist, explorer, businesspersons are all being explored, studied for a long time that thing is got in the seabed, even has contributed the problem of energy throughout one's life.Because the complex environment factor, it is bigger to cause the seabed to get the difficulty of thing.In Japan's on July 31st, 2002 (putting down on July 31st, 14), the innovation and creation of a kind of " silt suction tapping equipment " were once disclosed, publication number is P2002-212970A.And the U.S. is in the patent of invention on February 11st, 1986 disclosed " deep-sea mining equipment ", and the patent No. is US4681372.Its result is not ideal.And examine ore deposit, materials such as nickel nuclear ore deposit, noble metal and dilute metal for enrich precious deposits such as the manganese that are housed in the seabed, at present, still do not find the method for excavating exploitation effectively.
Summary of the invention
The object of the present invention is to provide a kind of seabed fetching device, it can be lifted out the sea step by step with the sea bed material of 3400m depths, and with the horizontal direction ejection, thereby realize the purpose that thing is got in the seabed.
The present invention designs according to the jet phenomenon in the hydrodynamics.It utilizes a kind of fluid to be carrier, through quickening to form high-velocity fluid, produces negative pressure at the ejiction opening place of high-velocity fluid, the suction subject matter; This high-velocity fluid is attaching the volume flow of water pump again spraying with sudden force, and the subject matter that is sucked is raised in jet pipe, reaches the purpose of getting thing.
Its solution is: get the sundries upper end and be connected with the expanding riser, get the sundries side and be connected with water pump, water pump is connected with the power source machine, constitutes seabed fetching device.
Get sundries by outer tube with and the interior pipe of interior setting constitute, between the tapering point of interior pipe and outer tube they the two, form narrow tapered channel, and at narrow tapered channel extension junction formation jet angle α, this jet angle α location produces the suction negative pressure and promotes thrust, and interior pipe is set in the sleeve pipe by a sleeve pipe and an end and the central tube that is connected with sleeve pipe constitutes.
The present invention is owing to take technique scheme, and it is not only simple in structure, and makes easily.Utilize seawater to be carrier, can be effectively with 3400m depths and proportion be 7.9 grammes per square metres/centimetre
3Sea bed material, be lifted out sea 3m eminence step by step, with the ejection of the speed along continuous straight runs of 1.525m/s, its spray volume is 1116kg/s, closes 4047T/h again, wherein contain proportion and be 7.9 grammes per square metres/centimetre
3Sea bed material 927T.Thereby can solve for a long time that people want to solve and a thing difficult problem is got in still unsolved seabed.
Description of drawings
Fig. 1 is the structural representation of seabed fetching device.
Fig. 2 is the user mode figure of seabed fetching device.
The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
Among Fig. 1, the two ends of outer tube 5 are connected with Taper Pipe 3 and Taper Pipe 8 respectively.In outer tube 5, be provided with interior pipe, it is made of sleeve pipe 6 and the overlapping central tube 10 that is set in it and is connected with Taper Pipe 12 for one that an end is connected with Taper Pipe 12, and sleeve pipe 6 supports 4 by uniform 3 and is connected with the inwall of outer tube 5, and central tube 10 is connected with the inwall of sleeve pipe 6 by 3 uniform supports 7.Between the tapering point of outer tube 5 and interior pipe they the two, form narrow tapered channel 13, form high-speed fluid ejection angle α in the extension junction of narrow tapered channel 13, and produce the suction negative pressure and promote thrust, constitute and get sundries in this jet angle α location.Taper Pipe 3 ends of outer tube 5 connect expanding riser 1 by connected jet pipe 2, and the nozzle diameter of expanding riser 1 upper end is 850mm, and are connected with on the top of expanding riser 1 and are 90 ° bend pipe.And Taper Pipe 8 ends are connected with a port of central tube 10, make the space that forms between the inner and outer pipe become the cavity of a sealing, and the port of central tube 10 that should the end place are suction ports 9, its inner diameter d
1=118mm.The side of outer tube 5 is connected with the water pump 14 that connects power motor 15 by connected water inlet pipe 11.The power of motor 15 is 2150kw, and the volume flow of water pump is 3000m
3/ h, the operating pressure of water pump is 34.8MPa.
Among Fig. 2, as the material r that is used to extract seabed, 3400m depths
1The time, can from bottom to top seabed fetching device be placed under water step by step.Except that the placement location of getting sundries 16 of the top one-level seabed fetching device apart from the 96.5m of sea, the placement location of getting sundries 16 of all the other each grade seabed fetching devices is 111.5m apart from the distance of the placement location of getting sundries 16 of adjacent seabed fetching device, as shown in Figure 2, its suction ports of getting sundries 16 of seabed fetching device 9 that is positioned over seabed, 3400m depths be extracted material r
1Be close, motor 15 drives water pumps 14 work, at them under the effect of the two, and can be with the material r that is extracted
1Rise to the eminence of 111.5m.By that analogy, the seabed fetching device of each grade placement is all adopted in a like fashion and is provided with, and except that the one-level seabed fetching device of the top, remaining all can reach above-mentioned hoisting depth.And topmost the one-level seabed fetching device get sundries 16 be place 96.5m place, extra large underwater be extracted material r
1Above, and expanding riser 1 will exceed seawater face 3m.
This seabed fetching device is carrier with the seawater, under the effect of motor 15 and water pump 14, seawater quickens in water inlet pipe 11 is flowed through the narrow tapered channel 13 of getting sundries, form high-velocity fluid, and spray towards the direction of jet angle α, this strand high-velocity fluid produces the suction negative pressure in jet angle α location, with sea bed material r
1Come up through central tube 10 suctions from the suction ports 9 of getting sundries 16, simultaneously, this strand high-velocity fluid is attaching the volume flow of water pump 14 again spraying with sudden force, under the effect of this jet thrust, makes the material r that suction comes up from central tube 10
1In jet pipe 2, be raised, through the speed along continuous straight runs ejection of the spout on expanding riser 1 top with 1.525m/s.Suction promotes so step by step, the most at last sea bed material r
1Rise to sea 3m eminence step by step, and along continuous straight runs is ejected on the cargo ship 17, thereby can realizes that the seabed gets the purpose of thing.
