The embodiment of the invention provides a submarine ore body harvesting and conveying device which comprises a harvesting device, an offshore operation device 50, a filling mechanism 30 and a conveying device 40. Specifically, the harvesting device is used for collecting seabed ore bodies; the offshore unit 50 is used for collecting a submarine ore body transported from the seabed to the sea; the inlet end of the filling mechanism 30 is communicated with the output end of the harvesting device; the conveying device 40 comprises a traction winch 41, a hoisting winch 42 and a mineral collection piece 45, the traction winch 41 is arranged on the harvesting device, and the traction winch 41 comprises a traction cable 43; hoist winch 42 is located at offshore unit 50, and hoist winch 42 includes hoist line 44; the collecting member 45 is connected to the hauling cable 43 and the hoisting cable 44, respectively; when the pulling cable 43 is pulled tight and the hoisting cable 44 is released, the mineral aggregates 45 are aligned with the outlet end of the filling organ 30; when the pull line 43 is released and the load line 44 is tensioned, the ore collecting member 45 is caused to transport the seabed ore body to the offshore working unit 50.
During operation, the collecting device is used for collecting the seabed ore bodies, the seabed ore bodies collected by the collecting device are output from the output end of the collecting device and enter the inlet end of the filling mechanism 30 and then come out from the outlet end of the filling mechanism 30, the hauling cable 43 is tensioned and the hoisting cable 44 is released, so that the ore collecting piece 45 is aligned with the outlet end of the filling mechanism 30, the seabed ore bodies coming out from the outlet end of the filling mechanism 30 can enter the ore collecting piece 45, when the ore collecting piece 45 is full of materials, the hauling cable 43 is released and the hoisting cable 44 is tensioned, so that the ore collecting piece 45 lifts the seabed ore bodies in the ore collecting piece 45, and the seabed ore bodies are conveyed to the offshore operation device 50.
It can be seen that the present embodiment provides for the movement of the mineral aggregates 45 back and forth between the outlet end of the filling means 30 and the offshore unit 50 by the cooperation of the tow cable 43 and the load cable 44 to convey the seafloor mineral bodies exiting the outlet end of the filling means 30 to the offshore unit 50. Moreover, by means of the tensioning and guiding action of the pulling cable 43, the alignment of the ore collecting element 45 with the outlet end of the filling element 30 is achieved, so that the manner in which the ore collecting element 45 acquires the seabed ore bodies is more reliable. Therefore, compared with the prior art that the submarine ore body is lifted through the circulating rotation of the conveying chain, the submarine ore body harvesting and conveying equipment is simple in structure, high in operation reliability, low in conveying cost of the submarine ore body and good in economical efficiency.
In order to improve the conveying efficiency, on the basis of the above embodiment, the outlet end of the filling mechanism 30 comprises a first outlet end and a second outlet end, and the first outlet end and the second outlet end are switchably communicated with the inlet end of the filling mechanism 30; the mineral aggregate 45 includes a first mineral aggregate 454 and a second mineral aggregate 455; the tractive lines 43 include a first tractive line 431 connected to the first mineral aggregate 454 and a second tractive line 432 connected to the second mineral aggregate 455; the hoisting cable 44 is one in number, and the first ore collection part 454 and the second ore collection part 455 are respectively connected to the hoisting cable 44; when the first tow cable 431 is tensioned and the load line 44 is released in the first direction, the first collection mineral 454 is aligned with the first outlet end of the filling mechanism 30 and the second collection mineral 455 is raised to the offshore unit 50; when the second tow cable 432 is pulled tight and the load line 44 is released in a second direction, the second mineral aggregate 455 is aligned with the second outlet end of the filling mechanism 30 and the first mineral aggregate 454 is raised to the offshore unit 50, wherein the first direction is opposite to the second direction. It will be appreciated that when the first pull cable 431 is tensioned and the load line 44 is released in the first direction, the second pull cable 432 is in a released state; when the second tractive line 432 is tensioned and the load line 44 is released in the second direction, the first tractive line 431 is in the released state.
It can be seen that in this embodiment, the filling mechanism 30 includes two outlet ends (i.e., a first outlet end and a second outlet end) which are switchable to enable the first mineral collection member 454 and the second mineral collection member 455 to be aligned with the two outlet ends, respectively, so that the first mineral collection member 454 and the second mineral collection member 455 can alternately collect the seabed mineral bodies. The first ore collecting part 454 and the second ore collecting part 455 are linked by connecting the first ore collecting part 454 and the second ore collecting part 455 to the same hoisting cable 44, so that when one of the first ore collecting part 454 and the second ore collecting part 455 ascends, the other one descends, that is, although the moving directions of the first ore collecting part 454 and the second ore collecting part 455 are opposite, the first ore collecting part 454 and the second ore collecting part 455 act at the same time, and the moving processes are overlapped, which is beneficial to improving the conveying efficiency. Furthermore, the first mineral aggregate 454 and the second mineral aggregate 455 have opposite moving directions and are mutually weighted, which is beneficial to improve the flexibility of the movement of the load-lifting cable 44 and reduce the lifting force of the load-lifting cable 44.
It should be noted that in this embodiment, during the process of moving one of the first ore collection member 454 and the second ore collection member 455 from the outlet end of the filling mechanism 30 to the offshore unit 50 and moving the other one from the offshore unit 50 to the corresponding outlet end of the filling mechanism 30, the feeding of the undersea ore body from the output end of the harvesting device to the inlet end of the filling mechanism 30 may be temporarily stopped, so as to prevent the undersea ore body from flowing out of the outlet end of the filling mechanism 30 when neither of the first ore collection member 454 nor the second ore collection member 455 is aligned with the outlet end of the filling mechanism 30.
It should be noted that, in the present embodiment, the ore collecting members 45 are divided into the first ore collecting members 454 and the second ore collecting members 455 according to the moving direction of the ore collecting members 45, and the number of the first ore collecting members 454 and the number of the second ore collecting members 455 are not limited, for example, in one embodiment, the number of the first ore collecting members 454 and the number of the second ore collecting members 455 are both one, and the first ore collecting members 454 and the second ore collecting members 455 are respectively disposed at two ends of the hoisting cable 44. In other embodiments, the number of the first ore collecting members 454 and the second ore collecting members 455 may be multiple, the multiple first ore collecting members 454 are arranged at intervals, and the moving directions of the multiple first ore collecting members 454 are always the same; the second ore collecting pieces 455 are arranged at intervals, and the moving directions of the second ore collecting pieces 455 are always the same; as long as a one-to-one correspondence of the first and second collections of minerals 454, 455 moves to the offshore unit 50 when one first collection of minerals 454 is aligned with the first outlet end of the filling mechanism 30; when a second aggregate 455 is aligned with the second outlet end of the filling mechanism 30, the first aggregate 454 is moved to the offshore unit 50.
Although the above embodiment can improve the conveying efficiency, the harvesting device and the filling mechanism 30 have waiting time, and seamless connection cannot be realized between harvesting and transportation, and in order to solve the technical problem, the overall efficiency of the seafloor mining is improved, in another embodiment, the outlet end of the filling mechanism 30 comprises a first outlet end and a second outlet end, and the first outlet end and the second outlet end are in switchable communication with the inlet end of the filling mechanism 30; the mineral aggregate 45 includes a first mineral aggregate 454 and a second mineral aggregate 455; the tractive lines 43 include a first tractive line 431 connected to the first mineral aggregate 454 and a second tractive line 432 connected to the second mineral aggregate 455; the load line 44 comprises a first load line 441 and a second load line 442, the first load line 441 being connected to the first collection mineral 454 and the second load line 442 being connected to the second collection mineral 455; aligning the first mine collection piece 454 at the first exit end when the first pull cable 431 is pulled tight and the first lift cable 441 is released; when the first tow cable 431 is released and the first lift cable 441 is tensioned, the first gather element 454 is raised to the offshore unit 50; aligning the second mineral gathering member 455 to the second exit end when the second haul cable 432 is tensioned and the second hoisting cable 442 is released; when the second haul line 432 is released and the second load line 442 is tensioned, the second mineral aggregate 455 is raised to the offshore unit 50.
It can be seen that the filling mechanism 30 in this embodiment also includes two outlet ends (i.e., a first outlet end and a second outlet end) which are switchable to enable the first mineral collection member 454 and the second mineral collection member 455 to be aligned with the two outlet ends, respectively, so that the first mineral collection member 454 and the second mineral collection member 455 can alternately collect the seabed mineral bodies. However, unlike the above-described embodiment, the present embodiment forms two sets of independent conveyance mechanisms by providing the first and second mineral aggregates 454 and 455, the first and second pulling cables 431 and 432, and the first and second hoisting cables 441 and 442, the first mineral aggregate 454, the first pulling cable 431 and the first hoisting cable 441 being one set of conveyance mechanism, and the second mineral aggregate 455, the second pulling cable 432 and the second hoisting cable 442 being the other set of conveyance mechanism.
In operation, when the first pull cable 431 is pulled downward while releasing the first lift cable 441, the first mineral aggregate 454 is moved to the first outlet end of the filling mechanism 30, at which time the first outlet end of the filling mechanism 30 is in communication with the inlet end thereof, and the seafloor mineral bodies fed from the harvesting device into the filling mechanism 30 exit the first outlet end and fall into the first mineral aggregate 454, and when the first mineral aggregate 454 is filled with seafloor mineral bodies, the first lift cable 441 is pulled upward while releasing the first pull cable 431, causing the first mineral aggregate 454 to convey the seafloor mineral bodies to the offshore unit 50. Before the first mineral aggregate 454 fills the seafloor mineral body, the second pull cable 432 is pulled downward while the second hoist cable 442 is released to move the second mineral aggregate 455 to the second outlet end of the filling mechanism 30, when the first mineral aggregate 454 fills the seafloor mineral body, the communication of the filling mechanism 30 is switched to communicate the second outlet end of the filling mechanism 30 with the inlet end thereof, and the seafloor mineral body fed from the recovery device to the filling mechanism 30 exits the second outlet end and falls into the second mineral aggregate 455, and when the second mineral aggregate 455 fills the seafloor mineral body, the second hoist cable 442 is pulled upward while the second pull cable 432 is released to allow the second mineral aggregate 455 to deliver the seafloor mineral body to the offshore unit 50. The first ore collecting member 454 and the second ore collecting member 455 work alternately to collect the seabed ore bodies coming out from the first outlet end and the second outlet end of the filling mechanism 30 in a seamless manner, so that the seabed ore bodies fed into the filling mechanism 30 from the harvesting device can be continuously output, seamless connection from collection to transportation is realized, the seabed ore bodies can be continuously mined, and the overall efficiency of seabed mining can be improved.

In addition, when the above-mentioned two sets of mutually independent conveying mechanisms are adopted to realize the alternate operation of the first ore collecting member 454 and the second ore collecting member 455, in order to balance the forces of the first ore collecting member 454 and the second ore collecting member 455 and reduce the lifting forces of the first lifting cable 441 and the second lifting cable 442, on the basis of the above-mentioned embodiment, the first lifting cable 441 is provided with the first counterweight member 47, and the moving direction of the first counterweight member 47 is opposite to the moving direction of the first ore collecting member 454; the second load line 442 is provided with a second counterweight 47, the second counterweight 47 moving in the opposite direction to the second collecting member 455. That is, when the first ore collecting member 454 ascends, the first balance weight member 47 descends; when the first ore collecting member 454 descends, the first weight member 47 ascends; similarly, when the second ore collecting member 455 ascends, the second weight member 47 descends; when the second ore collecting member 455 descends, the second weight member 47 ascends. The first counterweight 47 is capable of balancing the force of the first mine collection member 454; the second counterweight 47 is able to balance the forces of the second gathering member 455, making the movement of the first and second load cables 441, 442 more flexible.
