An Adaptive Suppression Device for Deep-Sea Mining Collection Plumes

Abstract

The present invention discloses an adaptive suppression device for collecting plume in deep-sea mining. Driven by a propulsion hydraulic cylinder, the horizontal moving roller can move horizontally along three cylindrical guide rails, thereby realizing the circumferential position adjustment of the corrugated environmental protection cover connected to the horizontal moving roller. The adjustment method of the corrugated environmental protection cover is as follows: the first control hydraulic cylinder and the second control hydraulic cylinder are used to push the expansion and contraction of the corrugated environmental protection cover, thereby realizing the control of the size of the corrugated environmental protection cover and suppressing the diffusion problem of the collected plume. At the same time, a suction pipe is assembled at the center of the corrugated environmental protection cover 3, and the collected plume can be suctioned through the suction action, further weakening the influence of the collected plume. Therefore, the adaptive suppression device adjusts the relative positions of the corrugated environmental protection cover in the axial and radial directions and the size of the corrugated environmental protection cover, thereby effectively suppressing the collected plume.

Description

Technical Field

[0001] The present invention belongs to the technical field of seabed mining, and particularly relates to an adaptive suppression device for deep-sea mining plume collection. Background Art

[0002] In the past 30 years, various countries have successively carried out exploration and development activities of deep-sea mineral resources. The commercially valuable seabed mineral resources that have been proven include polymetallic nodules, cobalt-rich ferromanganese nodules, and polymetallic sulfides, etc. An industrial mining process for the first two has been initially formed. Polymetallic sulfides are another new type of seabed mineral resource recognized by humans later. It contains multiple metal components and has high mining value, but it is still in the stage of exploration and experimental mining.

[0003] Seabed polymetallic sulfides are another type of seabed polymetallic mineral resource after polymetallic nodules and cobalt-rich crusts, rich in metal elements such as Cu, Fe, Zn, Mn, Pb, and rare metal elements such as Ag, Au, Co, and Mo. The resource volume of a single sulfide deposit can reach up to 1.0×108t at most. It has the advantages of being easy to smelt and having a huge resource volume, and is considered to be one of the deep-sea mineral resources that may be utilized by humans earliest. Polymetallic sulfide deposits can be divided into two categories according to their occurrence: one is the loose metal-containing sediment in the form of soil, such as the metal-containing sediment (metal mud) in the Red Sea; the other is the consolidated hard massive sulfide, related to the hydrothermal vent deposition of the ocean ridge "black chimney", such as the massive sulfide in the East Pacific Ocean Ridge. According to the chemical composition, it can be divided into four categories: the first category is rich in cadmium, copper, and silver, produced in the Galapagos Ridge in the East Pacific Ocean; the second category is rich in silver and zinc, produced in the Juan de Fuca Ridge and the Guaymas Basin; the third category is rich in copper and zinc; the fourth category is rich in zinc and gold, produced simultaneously with the third category.

[0004] The polymetallic sulfides are mined from the seabed, then cut and broken by tools, transported into the collection device, and further processed. The plume generated during the jet flow and walking of the mining vehicle, and the plume generated during the process of cutting and breaking the polymetallic sulfides, also known as the plume, once generated, will have a catastrophic impact on the marine environment. The large-scale diffusion of the plume can lead to the inability to carry out subsequent deep-sea mining operations. Therefore, the plume affects the efficiency and environmental protection of seabed mining operations and needs to be improved. Summary of the Invention

[0031] As Figures 1 to 15 shown, an embodiment of the present invention provides a schematic diagram of the structure of an adaptive suppression device for collecting plume in deep - sea mining.

A plurality of pick assemblies 21 are provided on the hemispherical surface of the mining head 1, and the pick assemblies 21 are used for the deep - sea metal layer. The mining head 1 is connected to the output shaft 17 of a drive motor 16 through a coupling 15. The drive motor 16 is fixed on the mining head support frame 2. A third rolling bearing 14 is further provided at the end of the mining head support frame 2, and the third rolling bearing 14 is assembled on the rotating shaft 22 of the mining head 1.

[0032] A first rolling bearing 10 and a second rolling bearing 11 are welded on the mining head support frame 2. A rotating drum 8 is welded on the outer shells of the first rolling bearing 10 and the second rolling bearing 11. A horizontal moving drum 7 is sleeved on the rotating drum 8. One side of the mining head support frame 2 is connected to a worm - gear and worm rotary motor 12. One end of the rotating drum 8 is fixed to the worm - gear and worm rotary motor 12 by screws. The horizontal moving drum 7 is connected to the worm - gear and worm rotary motor 12 through a propulsion hydraulic cylinder 13.

[0033] The adaptive suppression device further includes a corrugated environmental protection cover 3 on one side of the mining head 1. The corrugated environmental protection cover 3 is fixed on the horizontal moving drum 7 through a connecting bracket. The corrugated environmental protection cover 3 is a telescopic environmental protection cover, and can autonomously adjust the size of the environmental protection cover according to the collected plume generated by the real - time working conditions.

[0034] Three cylindrical guide rails 9 are circumferentially fixed on the rotating drum 8. Three cylindrical long holes are provided inside the horizontal moving drum 7, and the three cylindrical guide rails 9 are inserted into the three cylindrical long holes so that the horizontal moving drum 7 and the rotating drum 8 are coaxially matched, and the rotation of the horizontal moving drum 7 and the rotating drum 8 is synchronous. Under the push of the propulsion hydraulic cylinder 13, the horizontal moving drum 7 can move horizontally along the three cylindrical guide rails 9, thereby realizing the adjustment of the axial position of the corrugated environmental protection cover 3 on the mining head 1.

[0035] The corrugated environmental protection cover 3 is also provided with a suction pipeline 18, which is used to suck the collected plume, further weakening the influence of the collected plume. A first control hydraulic cylinder 4 is arranged on the right corrugated structure of the corrugated environmental protection cover 3, and the first control hydraulic cylinder 4 is used to control the expansion and contraction of the right corrugated structure of the corrugated environmental protection cover 3. A second control hydraulic cylinder 5 is arranged on the left corrugated structure of the corrugated environmental protection cover 3, and the second control hydraulic cylinder 5 is used to control the expansion and contraction of the left corrugated structure of the corrugated environmental protection cover 3.

[0036] As above, an adaptive suppression device for the collected plume in deep-sea mining of this embodiment is to solve the problem of the collected plume during deep-sea mining.

The other end of the worm and gear rotary motor 12 is fixed on the mining head support frame 2. Driven by the worm and gear rotary motor 12, the rotating drum 8 is driven to rotate, further driving the rotation of the horizontal moving drum 7 assembled on the rotating drum 8, thereby realizing the regulation of the circumferential position of the corrugated ore collecting cover 3. Among them, 3 cylindrical guide rails are evenly fixed in the circumferential direction of the rotating drum 8, and 3 cylindrical long holes are also evenly arranged inside the horizontal moving drum 7. Therefore, the horizontal moving drum 7 is coaxially matched with the rotating drum 8, and the rotation of the spiral drum 8 and the rotation of the horizontal moving drum 7 are synchronous. Under the push of the propulsion hydraulic cylinder 13, the horizontal moving drum 7 can be realized to move horizontally along the 3 cylindrical guide rails. Furthermore, the circumferential position adjustment of the corrugated environmental protection cover 3 connected to the horizontal moving drum 7 is realized. The corrugated environmental protection cover 3 is a telescopic environmental protection cover, which can autonomously adjust the size of the environmental protection cover according to the collected plume generated by the real-time working conditions. The adjustment method is as follows: through the first control hydraulic cylinder 4 and the second control hydraulic cylinder 5, the expansion and contraction of the corrugated environmental protection cover 3 are pushed, thereby realizing the control of the size of the corrugated environmental protection cover 3 and suppressing the diffusion problem of the collected plume. At the same time, a suction pipeline 18 is assembled at the center of the corrugated environmental protection cover 3, and the collected plume can be sucked through the suction effect, further weakening the influence of the collected plume. Therefore, according to the sonar, the size of the real-time collected plume under the deep-sea mining working conditions can be obtained, and the relative positions of the axial and radial directions of the corrugated environmental protection cover and the size of the corrugated environmental protection cover are adjusted, thereby realizing the effective suppression of the collected plume.
