Description

Technical Field

[0001] The present invention relates to the technical field related to deep-sea resource mining, and in particular to a deep-sea mining device with plume blocking. Background Art

[0002] Current deep-sea mining technologies face the severe challenge of inadequate plume control. Deep-sea mining activities, whether harvesting polymetallic nodules or mining metal-rich sulfides near hydrothermal vents, inevitably disturb seafloor sediments and generate large plumes. These plumes contain not only suspended solid particles directly generated by mining but also large amounts of natural sediment. Once these plumes spread to the surrounding waters, they significantly increase water turbidity, affecting the illumination of marine ecosystems and altering the optical properties of the water, with irreversible impacts on the habitat of benthic organisms. Furthermore, suspended particles in the plumes can migrate with ocean currents, spreading to waters far from the mining site, impacting wider ecosystems and even disrupting the migration paths of other marine life.

[0003] Existing plume control methods, such as the use of traditional barriers and filters, have obvious limitations. First, these methods often rely on preset static structures, which are difficult to cope with the complex terrain changes and unpredictable hydrodynamic conditions in the deep-sea environment, resulting in poor plume control. Secondly, the deployment and recovery process of traditional blocking devices is complicated and time-consuming, which not only increases mining costs but also reduces operational efficiency. Furthermore, such devices are usually made of rigid materials and lack sufficient adaptability and flexibility, making it difficult to maintain structural integrity and stability in deep-sea pressure environments. Finally, while traditional methods control the spread of plumes, they often cause additional damage to the seabed topography and benthic ecological environment.

[0004] As can be seen from the above, the existing marine mining equipment has the problem that the reserved processing equipment is poor in effect and thus affects the marine environment. Summary of the Invention

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0036] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0037] In order to solve the problem in the prior art that the reserved processing equipment of marine mining equipment has poor effect, which affects the marine environment, the present application provides a deep-sea mining device with plume blocking, which is used for deep-sea seabed mining. The present application uses 3D printing technology to construct a tunnel-shaped cover 30 to block the plume and provide a place for marine organisms to attach, thereby overcoming the problem of affecting the marine environment.

[0038] like Figures 1 to 8 As shown, the deep-sea mining device with plume blocking includes a mining vehicle, a ground spike 20, a mounting assembly 60 and a printing assembly. The mining vehicle includes a frame 10 and a track wheel arranged at the bottom of the frame 10. The arrangement of the track wheel is conducive to ensuring the smooth movement of the mining vehicle. A plurality of ground spikes 20 are provided. The frame 10 has a mounting frame 50 for mounting the ground spikes 20. The plurality of ground spikes 20 are arranged on the mounting frame 50. The mounting assembly 60 is arranged at the front end of the frame 10. The mounting assembly 60 drives the ground spikes 20 to be fixed to the seabed. The printing assembly is arranged on the frame 10. The printing assembly at least includes The first 3D printer 410 and the second 3D printer 420 are provided. The first 3D printer 410 is provided at the front end of the vehicle frame 10, and the second 3D printer 420 is provided at the rear end of the vehicle frame 10. The first 3D printer 410 prints and forms protective walls 310 on the ground spikes 20 fixed to the seabed. Opposite and continuous protective walls 310 are formed on both sides of the width direction of the vehicle frame 10. The second 3D printer 420 prints and forms a protective cover 320 between the two rows of protective walls 310. The two rows of protective walls 310 and the protective cover 320 form a cover body 30 for plume blocking.

[0039] Among them, the first 3D printer 410 is arranged at the front end of the frame 10 to form a front end printing area, and the second 3D printer 420 is arranged at the rear end of the frame 10 to form a rear end printing area. The front end printing area and the rear end printing area respectively form a protective wall 310 and a protective cover 320, so that when the mining vehicle moves, the front end printing area prints on the ground nails 20 to form a protective wall 310, and the rear end printing area moves to the area of ​​the protective wall 310 to form a protective cover 320 on the protective wall 310. The 3D printing of the front end area and the rear end area is conducive to the rapid printing and construction of the cover body 30.

[0040] In this embodiment, the protective cover 320 is an arched plate structure that bulges toward one side of the top of the frame 10. When printing the protective cover 320, the second 3D printer 420 prints the arched plate structure, which is beneficial to strengthening the structural strength of the cover body 30 so as to ensure that the cover body 30 is stably set on the seabed.

[0041] In this embodiment, the height of the protective wall 310 is not less than the height of the track wheel, thereby forming a relatively high protective wall 310 to completely block the plume generated by the first track wheel, further blocking the plume and protecting the marine environment. In this embodiment, it is preferred that the height of the protective wall 310 is higher than the height of the track wheel.

[0042] This application uses the flexible deployment of 3D printers and the stable support of ground spikes 20 to jointly build an efficient plume control system, which not only reduces damage to the seabed ecology, but also improves the mineral recovery rate, providing strong technical support for the sustainable development of deep-sea resources.

[0043] Specifically, the first 3D printers 410 are arranged in pairs, and the two first 3D printers 410 arranged in pairs are arranged in one-to-one correspondence with the two drive structures 610. The two drive structures 610 insert the two ground spikes 20 into the seabed respectively. The two first 3D printers 410 print to form protective walls 310 on the two ground spikes 20 respectively. As the mining vehicle moves forward, the ground spikes 20 are inserted into the seabed in turn by the drive structure 610. The first 3D printers 410 print to form protective walls 310 on the ground spikes 20, thereby forming two rows of protective walls 310 on both sides of the mining vehicle in the width direction.

[0044] Since the protective wall 310 is set on the ground nails 20, the ground nails 20 and the protective wall 310 need to be set correspondingly. They can be set one to one, and one protective wall 310 can be printed on one ground nail 20; or one protective wall 310 can be printed on two ground nails 20 to form a protective wall 310, and the number of ground nails 20 is greater than the number of protective walls 310.

[0045] It should be noted that the row of protective walls 310 is formed by sequentially cooperating with multiple protective walls 310. The protective walls 310 are arranged in rows along the length of the vehicle frame 10. The vehicle frame 10 is positioned between two rows of protective walls 310, and the 3D-printed cover 30 completely blocks the plume, thereby ensuring the plume blocking effect and improving marine environmental protection.

[0046] The deep-sea mining device provided in this application achieves effective blocking and sedimentation control of plumes by integrating a 3D printing technology ground nail 20 fixing mechanism, significantly improving the environmental friendliness and efficiency of deep-sea mining operations.

[0047] like Figures 4 to 7As shown, the first 3D printer 410 has a first material storage tank 411, and the second 3D printer 420 has a second material storage tank 421. The deep-sea mining device with plume blocking also includes a distributor and a printing material delivery pipe. The distributor is arranged on the frame 10, and the distributor is respectively connected to the first material storage tank 411 and the second material storage tank 421. The printing material delivery pipe is arranged on the frame 10, and the first end of the printing material delivery pipe is connected to the distributor, and the second end of the printing material delivery pipe extends to the sea surface for connection with the feeding device.

[0048] The second end of the printing material delivery pipe is connected to the feeding equipment of the overseas part, and the first end of the printing material delivery pipe provides PHA printing material or PLA printing material to the distributor.

[0049] Specifically, the material distributor used in the present application can provide a target amount of printing material to the first 3D printer 410 and the second 3D printer 420 respectively, so as to reasonably distribute the materials according to actual usage, thereby improving printing efficiency.

[0050] The first material storage tank 411 is connected to the material distributor, and the first 3D printer 410 also includes a first print head 412, which is used to print and form the protective wall 310; the second material storage tank 421 is connected to the material distributor, and the second 3D printer 420 also includes a second print head 422, which is used to print and form the protective cover 320.

[0051] In this embodiment, the cover body 30 is formed of PHA printing material or PLA printing material, and the printing feed pipe 70 transports the printing material to the first 3D printer 410 and the second 3D printer 420. The first 3D printer 410 and the second 3D printer 420 can heat the printing material to make the printing material uniform. At the same time, the first 3D printer 410 and the second 3D printer 420 spray the printing material through high pressure. The first 3D printer 410 sprays the printing material through high pressure so that the printing material adheres to the ground nail 20 to form a protective wall 310. The protective wall 310 can be quickly cooled and solidified in seawater. The second 3D printer 420 sprays the printing material onto the protective wall 310, forming a protective cover 320 on the protective wall 310 to form the cover body 30. The cover body 30 is supported on the seabed to form a tunnel structure, which can prevent the spread of the plume.

[0052] The deep-sea mining device of the present application uses 3D printing technology to construct a protective wall 310 and a protective cover 320 to form a tunnel-shaped cover body 30, which blocks the plume, achieves precise control and sedimentation of the plume, and effectively reduces the impact on the seabed ecological environment; the protective wall 310 is set on the ground nail 20 to ensure the stability and reliability of the plume blocking structure and improve the safety of the operation.

[0053] like Figures 1 to 6As shown, the mounting assembly 60 includes a driving structure 610 and a conveying structure 620. Two driving structures 610 are provided, and the two driving structures 610 are spaced apart along the width direction of the frame 10. The driving structure 610 is provided at the front end of the mining vehicle. Along the length direction of the frame 10, the first 3D printer 410 is provided between the driving structure 610 and the second 3D printer 420. The conveying structure 620 is provided between the mounting frame 50 and the driving structure 610 for conveying the ground spikes 20. The driving structure 610 has a driving portion that moves back and forth along the height direction of the frame 10. The two driving structures 610 respectively drive the ground spikes 20 to be fixed to the seabed.

[0054] Among them, two driving structures 610 are provided on the frame 10 and are used to insert the ground spikes 20 into the seabed respectively, so as to realize that the ground spikes 20 arranged at intervals along the width direction of the frame 10 are inserted into the seabed.

[0055] Specifically, the distance between the two driving structures 610 is greater than the width of the frame 10 , so that the two ground spikes 20 are disposed outside the frame 10 area.

[0056] The driving structure 610 includes a support plate 611, a driving member and a support frame 612. The support plate 611 is arranged on the frame 10. The support plate 611 has a pressure block slidingly arranged along the height direction of the frame 10. The driving member is arranged on the support plate 611. The driving member has a driving part, which is driven and connected to the pressure block to provide driving force for the sliding of the pressure block. The support frame 612 is arranged on the support plate 611. The support frame 612 is opposite to the output end of the conveying structure 620. The support frame 612 supports the ground nail 20 and is used to provide a damping force to limit the ground nail 20 from moving toward the seabed along the height direction of the frame 10. The driving member drives the ground nail 20 to move toward the seabed through the pressure block.

[0057] In this embodiment, the driving member is a motor, which drives the pressure block to move back and forth along the height direction of the frame 10, thereby enabling the ground nail 20 to be inserted into the seabed. The support frame 612 is used to support the ground nail 20. The ground nail 20 is moved from the conveying structure 620 to the driving structure 610 and supported on the support frame 612. The driving member presses the ground nail 20 toward the seabed through the pressure block and drives the ground nail 20 to move toward the seabed, so as to enable the ground nail 20 to be inserted into the seabed. The specific structure of the support frame 612 can be an annular structure, and a plurality of circumferentially spaced support blocks are provided on the inner circumferential wall surface of the annular structure. The support blocks can undergo elastic deformation, and the ground nail 20 abuts against the top surface of the support block. When the pressure block presses the ground nail 20, the ground nail 20 drives the support block to deform to avoid the ground nail 20 passing through the support frame 612 and moving toward the seabed.

[0058] In this embodiment, along the length direction of the vehicle frame 10 , the distance between the first 3D printer 410 and the driving structure 610 is smaller than the distance between the first 3D printer 410 and the second 3D printer 420 .

[0059] In the present application, the first 3D printer 410 is arranged adjacent to the driving structure 610 , so that after the driving structure 610 inserts the ground spike 20 into the seabed, the first 3D printer 410 can quickly print on the ground spike 20 to form the protective wall 310 .

[0060] like Figures 1 to 3 and Figure 8 As shown, the protective wall 310 is arranged in a one-to-one correspondence with the ground nail 20. The ground nail 20 includes a plug-in section at the bottom end arranged along the height direction of the frame 10, a supporting section in the middle and a fixed section at the top. The supporting section is formed into a disc-shaped structure, and the projections of the plug-in section and the fixed section on the supporting section are both located inside the supporting section. The protective wall 310 is arranged on the top surface of the supporting section and the fixed section.

[0061] Among them, the first 3D printer 410 prints on the fixed section to form a protective wall 310, the supporting section is supported on the conveying structure 620 for transportation, and at the same time the supporting section is used to support on the support frame 612, and the plug-in section is used to insert into the seabed. The plug-in section is a needle-shaped structure to improve the plug-in efficiency and plug-in stability, ensuring that the ground nail 20 is quickly and stably inserted and fixed to the seabed.

[0062] In this embodiment, the mounting frame 50 is arranged between the first 3D printer 410 and the second 3D printer 420 along the length direction of the frame 10. The mounting frame 50 and the driving structure 610 are arranged in a one-to-one correspondence. The mounting frame 50 is a cylindrical structure extending along the height direction of the frame 10. A plurality of ground spikes 20 are abutted against the inside of the mounting frame 50. The mounting frame 50 has a bottom opening, and the conveying structure 620 is arranged below the bottom opening.

[0063] There are two mounting frames 50 , which correspond to two driving structures 610 respectively. The provision of two mounting frames 50 is conducive to reasonable structural setting to avoid affecting the design size of the frame 10 and the flexibility of the structure.

[0064] Specifically, the cylindrical structure of the mounting frame 50 is conducive to the installation of multiple ground nails 20. Multiple ground nails 20 can continuously provide ground nails 20 to the conveying structure 620, and the cylindrical structure of the mounting frame 50 can use the gravity of the ground nails 20 to realize the movement of the ground nails 20 toward the conveying structure 620. In order to avoid the ground nails 20 from moving toward the conveying structure 620 when there is no need to insert the ground nails 20 into the seabed, the present application is provided with a blocking member at the bottom end of the mounting frame 50, and the position of the blocking member can be controlled to avoid or abut against the ground nail 20. When abutting against the ground nail 20, the blocking member abuts against the bottom surface of the support section to limit the movement of the ground nail 20 toward the seabed.

[0065] like Figure 3 As shown, there are two conveying structures 620, and both conveying structures 620 have an arc-shaped avoidance portion for avoiding the first 3D printer 410. The conveying structure 620 is a conveyor belt, and the conveyor belt has an avoidance hole extending in the same direction as the conveyor belt. The plug-in section of the ground nail 20 passes through the avoidance hole, the supporting section abuts against the conveyor belt, and the fixed section is arranged above the conveyor belt.

[0066] Among them, the conveying structure 620 adopts a conveyor belt, and the supporting section of the ground nail 20 is supported on the conveyor belt. Under the drive of the driving member, the conveyor belt drives the ground nail 20 to move toward the driving structure 610. The avoidance holes set on the conveyor belt can ensure that the ground nail 20 maintains the numerical setting, thereby enabling the ground nail 20 to reach the driving structure 610. The plug-in section of the ground nail 20 remains set toward the seabed side, and the ground nail 20 can be directly driven to be inserted into the seabed without the need to adjust the position of the ground nail 20, thereby improving the plug-in efficiency of the ground nail 20, and thereby improving the molding efficiency of the cover body 30.

[0067] Of course, the conveying structure 620 of the present application is not limited to the above-mentioned conveyor belt, and can also adopt a robot arm to clamp the ground nails 20 and transfer them to the support frame 612 of the driving structure 610.

[0068] In this embodiment, two conveying structures 620 are used in conjunction with two mounting frames 50 and two driving structures 610 to achieve independent insertion of the ground nails 20 on both sides of the width direction of the frame 10 into the seabed. This not only improves the insertion efficiency of the ground nails 20, but also prevents the insertion of the ground nails 20 on both sides from interfering with each other, further ensuring the insertion efficiency of the ground nails 20.

[0069] like Figures 1 to 7 As shown, the printing assembly also includes a first frame 430 and a second frame 440. The first frame 430 is arranged on the frame 10 and is located above the protective wall 310. The first 3D printer 410 slides on the first frame 430. The first print head 412 of the first 3D printer 410 passes through the first frame 430 and extends toward the side of the ground nail 20. The second frame 440 is arranged on the frame 10 and is located above the protective wall 310. The second 3D printer 420 is slidably arranged on the second frame 440 along the width direction of the frame 10. The second print head 422 of the second 3D printer 420 passes through the second frame 440 and extends toward the seabed.

[0070] The first frame 430 is used to install and position the first 3D printer 410 . The first 3D printer 410 is slidably mounted on the first frame 430 to print on the ground spikes 20 to form a protective wall 310 arranged along the length direction of the vehicle frame 10 .

[0071] Specifically, the printing assembly further includes a first drive member, which is disposed on the first frame 430 and is drivingly connected to the first 3D printer 410. The first drive member drives the first 3D printer 410 to move along the length of the vehicle frame 10. The first drive member is a motor that provides driving force for the first 3D printer 410 to reciprocate along the length of the vehicle frame 10, thereby ensuring that the first print head 412 of the first 3D printer 410 forms the protective wall 310 on the ground spikes 20.

[0072] The first print head 412 of the first 3D printer 410 in this embodiment is a retractable structure. The first print head 412 can be retracted by an electric telescopic rod or by being pushed by a motor. The retractable first print head 412 can enable the protective wall 310 to be formed in sequence along the height direction of the frame 10.

[0073] The second frame 440 is used to install and position the second 3D printer 420 . The second 3D printer 420 is slidably arranged on the slideway of the second frame 440 , thereby printing and forming the protective cover 320 between the two protective walls 310 .

[0074] In this embodiment, the printing assembly further includes a second drive member, which is disposed on the second frame 440 and is drivably connected to the second 3D printer 420. The second drive member drives the second 3D printer 420 to move along the width direction of the vehicle frame 10. The second drive member is a motor, which drives the second 3D printer 420 to slide along the second frame 440 to print the protective cover 320 disposed along the width direction of the vehicle frame 10. Since the mining vehicle is movable, the second print head 422 follows the movement of the mining vehicle, thereby forming the protective cover 320 disposed on the protective wall 310. Of course, an independent drive motor can also be provided to drive the second 3D printer 420 to move along the length direction of the vehicle frame 10, thereby assisting in printing and forming the protective cover 320.

[0075] In this embodiment, two second 3D printers 420 are provided, and the two second 3D printers 420 are slidably set on the second frame 440. Two second driving members are provided and are arranged one-to-one corresponding to the second 3D printers 420; under the driving action of the two second driving members, the two second 3D printers 420 approach or move away from each other along the width direction of the frame 10 to print and form the protective cover 320.

[0076] like Figure 2 and Figure 3As shown, the deep-sea mining device with plume blocking also retains a suction pipe 80 and a delivery pipe 70. A mineral storage chamber is provided on the vehicle frame 10. One end of the suction pipe 80 is communicated with the mineral storage chamber, and the other end of the suction pipe 80 has a mineral suction port arranged toward the seabed. One end of the delivery pipe 70 is communicated with the mineral storage chamber, and the other end of the delivery pipe 70 extends to the sea surface for supplying ore to the outside.

[0077] Among them, the distance between the mineral suction port and the seabed is less than the height of the track wheel. Such a structural setting is conducive to ensuring mining efficiency.

[0078] Specifically, the suction pipe 80 is used to suck the minerals on the seabed into the mineral storage chamber, and the delivery pipe 70 is used to transport the minerals inside the mineral storage chamber to overseas to realize the external supply of minerals.

[0079] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0080] The deep-sea mining device with plume blocking in the present application uses 3D printing technology to construct a protective wall 310 and a protective cover 320 to form a tunnel-shaped cover body 30, which blocks the plume, achieves precise control and sedimentation of the plume, and effectively reduces the impact on the seabed ecological environment; the protective wall 310 is set on the ground nail 20 to ensure the stability and reliability of the plume blocking structure and improve the safety of the operation.

[0081] The deep-sea mining device with plume blocking provided in this application achieves effective plume blocking and sedimentation control by integrating a 3D printing technology ground nail 20 fixing mechanism, significantly improving the environmental friendliness and efficiency of deep-sea mining operations.

[0082] This application uses the flexible deployment of 3D printers and the stable support of ground spikes 20 to jointly build an efficient plume control system, which not only reduces damage to the seabed ecology, but also improves the mineral recovery rate, providing strong technical support for the sustainable development of deep-sea resources.
