[0002] With the growing demand for deep-sea resource development, the adaptability of existing deep-sea mining equipment in high-pressure, low-temperature, complex terrain and high-water-content seabed sediment environments is limited. The research and development of deep-sea mining equipment faces multiple challenges, especially finding a balance between resource acquisition and environmental protection.

[0004] The present invention is based on the inventor's discovery and understanding of the following facts and problems: In the related technologies, deep-sea mining systems include trailer mining systems, continuous line mining systems and marine shuttle mining systems.

[0023] like Figure 1-Figure 8 As shown, the mining system 100 of the embodiment of the present invention includes a mining device 1, a mining ship 2, a transfer device 3 and a transport ship (not shown in the figure).

[0024] The mining device 1 comprises a walking assembly 11, a crushing assembly 12, a nozzle assembly 13 and a collecting assembly 14. The crushing assembly 12, the nozzle assembly 13 and the collecting assembly 14 are all arranged on the walking assembly 11. The walking assembly 11 is used for walking in the deep sea, the crushing assembly 12 is used for crushing seabed sediments, and the nozzle assembly 13 is used for spraying the crushed seabed sediments so that the crushed seabed sediments are flushed into the collecting assembly 14. Specifically, Figure 1 and Figure 3As shown, the crushing assembly 12, the nozzle assembly 13 and the collecting assembly 14 are all arranged on the walking assembly 11. The crushing assembly 12, the nozzle assembly 13 and the collecting assembly 14 are driven by the walking assembly 11 to walk in the deep sea, ensuring that the mining device 1 can move stably on the seabed and adapt to the complex seabed terrain. The crushing assembly 12 has crushing ability and wear resistance, and can crush the seabed sediments to ensure that the sediments are crushed into a particle size suitable for subsequent processing. The nozzle assembly 13 can spray high-pressure water to spray the crushed seabed sediments, so that the nozzle assembly 13 further refines the particle size of the sediments, and also makes the sediments rush up to obtain sufficient kinetic energy, so as to rush into the collecting assembly 14 to collect the sediments.

[0025] The mining ship 2 is suitable for floating on the sea surface, and the mining ship 2 is used to collect seabed sediments. Figure 1 As shown, the mining vessel 2 floats on the sea surface as a floating platform on the sea surface, which not only provides stable support for the mining device 1, but also can collect and store the seabed sediments collected by the mining device 1.

[0026] The transfer device 3 is connected to the collection assembly 14 and the mining ship 2 respectively, so that the seabed sediment collected by the collection assembly 14 is transported to the mining ship 2 through the transfer device 3. Specifically, Figure 1 and Figure 2 As shown, the transfer device 3 is located in the deep sea and is connected to the outlet of the collection assembly 14 and the inlet of the mining ship 2 respectively. The seabed sediments are quickly transferred to the mining ship 2 through the transfer device 3, thereby achieving seamless connection from the seabed to the sea surface.

[0027] The transport ship is suitable for floating on the sea surface, and the mining ship 2 cooperates with the transport ship and the transport ship can move on the sea surface relative to the mining ship 2, so that the seabed sediment on the mining ship 2 can be transported by the transport ship. Figure 1 As shown, the transfer ship floats on the sea surface and can move on the sea surface. The transport ship can transport the seabed sediments on the mining ship 2 to prevent excessive sediments on the mining ship 2 from affecting its mining efficiency, thereby reducing mining costs and safety risks.

[0028] The mining system 100 of the embodiment of the present invention is provided with a walking component 11, a crushing component 12, a nozzle component 13 and a collecting component 14. The crushing component 12 can realize precise excavation and cleaning, reduce disturbance to non-target areas, and the nozzle component 13 ensures that water flow impact is only performed in necessary areas, protects the surrounding seabed ecology, improves collection efficiency, and reduces damage to the seabed ecosystem, thereby realizing a more environmentally friendly mining method.

[0029] The mining system 100 of the embodiment of the present invention is provided with a mining device 1, a mining ship 2, a transfer device 3 and a transport ship. The mining device 1 accurately tracks a predetermined mining path to collect seabed sediments. The operation difficulty is small, the mining efficiency is high, and the adaptability to the seabed environment is strong. The seabed sediments are transported to the mining ship 2 through the transfer device 3 and then transported through the transport ship. Compared with the continuous line bucket mining system 100 of the related technology, there will be no entanglement accidents of the bucket, thereby ensuring production safety and mining efficiency, low cost, high stability and reliability.

[0030] In some embodiments, the transfer device 3 includes a first pipe 31 , an intermediate bin 32 , a first transport pump 33 and a second pipe 34 .

[0031] The first pipe 31 extends in the up-down direction and is a hard pipe body. The first pipe 31 is arranged below the mining ship 2 and connected to the mining ship 2. Specifically, Figure 1 and Figure 2 As shown, the first pipe 31 is a vertical hard pipe extending in the up-down direction. The first pipe 31 is arranged below the mining ship 2 and the upper end of the first pipe 31 is connected to the mining ship 2 .

[0032] The intermediate bin 32 is disposed below the mining vessel 2 and connected to the first pipe 31. The intermediate bin 32 is used to store seabed sediments. Both ends of the first transport pump 33 are respectively connected to the intermediate bin 32 and the first pipe 31, so that the seabed sediments are transported to the first pipe 31 through the first transport pump 33. Specifically, Figure 1 and Figure 2 As shown, the intermediate bin 32 is arranged at the lower end of the first pipe 31 and is connected to the first pipe 31, so that the first pipe 31 provides support and fixation for the intermediate bin 32 to prevent the intermediate bin 32 from being displaced due to factors such as water flow and seabed topography. The mining ship 2 can also drive the intermediate bin 32 to move in the deep sea through the first pipe 31. The inlet of the first transport pump 33 is connected to the outlet of the intermediate bin 32, and the outlet of the first transport pump 33 is connected to the first pipe 31, so that the seabed sediments in the intermediate bin 32 flow into the mining ship 2 through the first pipe 31.

[0033] The second pipe 34 is a soft pipe body and both ends of the second pipe 34 are connected to the intermediate chamber 32 and the collecting assembly 14, so that the crushed seabed sediment in the collecting assembly 14 is transported to the intermediate chamber 32 through the second pipe 34.

Since the second tube 34 is a soft tube body with high flexibility, the soft tube body can bend with changes in terrain, ensuring that the connection between the collecting component 14 and the intermediate chamber 32 is not affected, thereby ensuring the operating efficiency of the walking device on the seabed.

[0034] In some embodiments, the first pipe 31 includes a sub-pipe 311, and the plurality of sub-pipes 311 are connected in sequence. The transfer device 3 also includes a plurality of slurry pumps 312, and at least one slurry pump 312 is disposed between two adjacent sub-pipes 311 and is connected to the two adjacent sub-pipes 311, so that the slurry pump 312 can transport seabed sediments. Specifically, Figure 2 As shown, the first pipe 31 includes hard sub-pipes arranged in sequence along the up-down direction, and a slurry pump 312 is provided between the two sub-pipes 311. The inlet of the slurry pump 312 is connected to the lower sub-pipe 311, and the outlet of the slurry pump 312 is connected to the upper sub-pipe 311, so that the seabed sediments in the intermediate bin 32 are transported through the cooperation of the sub-pipes 311 and the slurry pump 312, thereby improving the transportation efficiency of the transfer device 3.

[0035] In some embodiments, the mining system 100 further includes a plurality of floating members 35, which are arranged on the second tube 34 and spaced apart along the length direction of the second tube 34. Specifically, the floating member 35 is a floating ball and is fixed on the second tube 34, so that the floating member 35 not only provides buoyancy for the second tube 34, but also improves the flexibility of the second tube 34, thereby preventing the second tube 34 from being damaged due to excessive bending or stretching. In addition, the floating member 35 can serve as a support point for the second tube 34, helping the second tube 34 to maintain a correct position and posture. Finally, the floating member 35 can serve as a marking point, which facilitates the staff to quickly locate the position of the second tube 34, thereby improving the maintenance efficiency of the second tube 34.

[0036] In some embodiments, the transfer device 3 further includes a mounting seat 37 and a second transport pump 36, the mounting seat 37 is connected to the first pipe 31, and the intermediate bin 32, the first transport pump 33 and the second transport pump 36 are all arranged on the mounting seat 37, and the two ends of the second transport pump 36 are respectively connected to the intermediate bin 32 and the collection assembly 14, so that the seabed sediment in the collection assembly 14 is transported to the intermediate bin 32 through the second transport pump 36. Specifically, as Figure 1As shown, the mounting seat 37 is fixedly installed on the first pipe 31, and the intermediate bin 32, the first transport pump 33 and the second transport pump 36 are all arranged on the mounting seat 37, so that the mounting seat 37 provides an installation basis for the intermediate bin 32, the first transport pump 33 and the second transport pump 36, and the inlet of the second transport pump 36 is connected to the outlet of the collecting component 14, and the outlet of the second transport pump 36 is connected to the inlet of the intermediate bin 32, so that the seabed sediments in the collecting component 14 are transported to the intermediate bin 32 through the second transport pump 36.

[0037] In some embodiments, the mining device 1 further includes a mounting frame 15, which is disposed on the traveling assembly 11 and is arranged relative to the traveling assembly 11 and around the width direction of the traveling assembly 11 (eg, Figure 4 The crushing assembly 12 and the collecting assembly 14 are rotatable in the front and rear directions shown in the figure. The crushing assembly 12 and the collecting assembly 14 are arranged on the mounting frame 15 so that the mounting frame 15 drives the crushing assembly 12 and the collecting assembly 14 to rotate. The collecting assembly 14 is arranged between the crushing assembly 12 and the walking assembly 11. The nozzle assembly 13 is arranged on the collecting assembly 14 and cooperates with the collecting assembly 14 so that the crushed seabed sediments are flushed into the collecting assembly 14. Specifically, as Figure 3 and Figure 4 As shown, the right end of the mounting frame 15 is hinged on the walking assembly 11 and rotates on the walking assembly 11 in the front-rear direction. The crushing assembly 12 and the collecting assembly 14 are arranged on the mounting frame 15, so that the mounting frame 15 drives the crushing assembly 12 and the collecting assembly 14 to rotate, so that the crushing assembly 12 and the collecting assembly 14 can adjust their angles as needed and approach the target mining point in the best posture. The crushing assembly 12 adopts high-strength wear-resistant materials to ensure that it can still work efficiently under high pressure and low temperature conditions. The crushing assembly 12 is rotatable at the left end of the mounting frame 15, and the collecting assembly 14 is arranged on the mounting frame 15 and The nozzle assembly 13 is located on the right side of the crushing assembly 12, and the nozzle assembly 13 is arranged on the collecting assembly 14 and cooperates with the collecting assembly 14. When collecting, the mounting frame 15 drives the crushing assembly 12 to move downward to contact the sediment on the seabed. The crushing assembly 12 rotates to crush the sediment. The crushing assembly 12 rotates clockwise and the walking assembly 11 moves to the left. When the inlet of the collecting assembly 14 moves to above the crushed sediment, the nozzle assembly 13 will spray high-pressure fluid (such as water or air) on the crushed sediment, so that the crushed sediment is flushed up and into the collecting assembly 14.

[0038] In some embodiments, the crushing assembly 12 includes a crushing roller 121 and a motor 122, the motor 122 is arranged on the mounting frame 15, the crushing roller 121 includes a cylinder 1211 and a plurality of crushing parts 1212, the cylinder 1211 is rotatably arranged on the mounting frame 15 and is connected to the motor 122, the crushing part 1212 includes a first section 1213 and a second section 1214 connected to each other, the first section 1213 extends along the radial direction of the cylinder 1211 and is arranged on the cylinder 1211, the second section 1214 extends along the circumferential direction of the cylinder 1211, the cross-sectional area of ​​the outer peripheral surface of the free section of the second section 1214 gradually decreases in the direction away from the first section 1213, and the plurality of crushing parts 1212 are arranged on the cylinder 1211 and are arranged in multiple rows along the axial direction of the cylinder 1211, and each row includes a plurality of crushing parts 1212 arranged along the circumferential direction of the cylinder 1211.

[0039] Specifically, Figure 6-Figure 8 As shown, the cylinder 1211 is rotatably disposed on the left end of the mounting frame 15, the motor 122 is disposed on the mounting frame 15 and the output shaft of the motor 122 is connected to the cylinder 1211, so that the cylinder 1211 is driven by the motor 122 to rotate on the mounting frame 15, and the cylinder 1211 is detachably disposed on the mounting frame 15, so that the structure of the crushing roller 121 can be replaced or adjusted according to the characteristics of the target ore to meet the collection requirements of different types of deep-sea ores, thereby ensuring the crushing efficiency of the crushing roller 121. The crushing member 1212 includes a first section 1213 and a second section 1214. The first section 1213 is fixed to the outer peripheral side of the cylinder 1211. The second section 1214 has a sharp front end so that the crushing member 1212 is generally in the shape of a pickaxe. The sharp front end is suitable for efficiently crushing seabed sediments.

The continuously rotating cylinder 1211 can maintain an efficient working rhythm during the excavation process, so that the ore can be quickly dug out, ensuring the crushing efficiency of the crushing roller 121. Whether it is soft mud or hard rock, it can be effectively crushed, thereby improving the applicability of the crushing component 12.

Specifically, as Figure 4 and Figure 5 As shown, the third pipe 141 is a collecting pipe and the outlet of the third pipe 141 is fixed on the walking assembly 11 and can be connected to the second transport pump 36.

The first nozzle 1322 is arranged on a side of the third pipe 141 adjacent to the crushing assembly 12. The first nozzle 1322 extends from top to bottom and is inclined toward a side away from the crushing assembly 12. Specifically, as Figure 3-Figure 5As shown, the first nozzle 1322 is made of high pressure resistant and corrosion resistant materials to ensure that it is not easily damaged during long-term use in a deep sea environment. The inlet of the first nozzle 1321 is connected to the outlet of the high pressure water pump 131. There are multiple first nozzles 1322, and the multiple first nozzles 1322 are sequentially arranged on the left side of the outlet of the third pipe 141 along the front-to-back direction. The first nozzle 1322 extends from top to bottom and tilts to the right. The multiple first nozzles 1322 are all connected to the first nozzle 1321, so that the spray water is sprayed out through the first nozzle 1322 through the first nozzle 1321. The setting of the first nozzle 1322 can make the water flow tilted to the right, and the angle and spray force of the first nozzle 1322 can be adjusted to adapt to different types of sedimentary layers and ore densities. The first nozzle 1322 can also accurately control the impact force by adjusting the water pressure and the spraying angle, which can effectively lift the ore without causing excessive disturbance to the surrounding sedimentary layers. Therefore, through the angle and position arrangement of the first nozzle 1322, loose ore can be effectively flushed from the sedimentary layer, ensuring that the water flow can penetrate into the sedimentary layer and generate sufficient thrust to lift the ore.

[0044] The second nozzle assembly 133 includes a second nozzle pipe 1331 and a second nozzle 1332. The two ends of the second nozzle pipe 1331 are connected to the high-pressure water pump 131 and the second nozzle 1332 respectively. The second nozzle 1332 is arranged on the side of the third pipe 141 away from the crushing assembly 12. The second nozzle 1332 extends from top to bottom and is inclined toward the side adjacent to the crushing assembly 12. Specifically, as Figure 3-Figure 5 As shown, the inlet of the second nozzle 1331 is connected to the outlet of the high-pressure water pump 131, and there are multiple second nozzles 1332. The multiple second nozzles 1332 are sequentially arranged on the right side of the outlet of the third tube 141 along the front-to-back direction. The second nozzles 1332 extend from top to bottom and tilt to the left. The multiple second nozzles 1332 are all connected to the second nozzle 1331, so that the spray water is sprayed out through the second nozzle 1331 through the second nozzle 1332. The setting of the second nozzle 1332 can make the water flow tilted to the left. The reverse water flow generated by the second nozzle 1332 forms a "water wall", which effectively prevents the ore from scattering backwards, so that the ore is concentrated near the cylinder 1211 for easy collection, and the confluence of the first nozzle 1322 and the second nozzle 1332 forms an upward thrust, which lifts the ore and guides it to the inlet of the third tube 141, ensuring that the ore can be smoothly transported to the third tube 141. In addition, the high-pressure water jets sprayed by the first nozzle assembly 132 and the second nozzle assembly 133 are not only used to lift and guide the ore, but also can quickly clean the mud and sediment on the surface of the cylinder 1211, reduce the friction between the cylinder 1211 and the ore, and improve work efficiency. Through the flushing of high-pressure water flow, the cylinder 1211 can be kept clean and avoid jamming and wear caused by mud and sand accumulation.

[0045] The present invention implements the mining system 100 through the arrangement of the crushing roller 121 and the nozzle assembly 13 to have the following advantages: 1. Reduce disturbance: The crushing roller 121 is mainly responsible for the excavation task, and the high-pressure water jet of the nozzle assembly 13 is used as an auxiliary tool to reduce the direct impact of the water jet on the sediment layer. The ore excavated by the crushing roller 121 is cleaned and guided by the water jet, which can better control the impact on the seabed sediment.

[0046] 2. Precise operation: Through the coordinated work of machinery (crushing roller 121) and water jet (nozzle assembly 13), precise excavation and cleaning can be achieved, reducing disturbance to non-target areas. Reasonable configuration of front and rear jets ensures that water flow impacts only in necessary areas to protect the surrounding seabed ecology.

[0047] 3. Reduce ecological damage: Pure water jet mining system 100 often causes a large amount of sediment to suspend, affecting the seabed ecosystem. By combining mechanical excavation and water jet, this design can reduce the scope of sediment suspension and diffusion, and reduce damage to the seabed ecological environment.

[0048] 4. Sediment control: The nozzle assembly 13 may be designed with multi-stage filtering and adjustment functions, which can control the intensity and direction of the water flow, avoid excessive disturbance of the sediment layer, and protect the living environment of the seabed organisms.

[0049] 5. Comprehensive protection measures: In addition to reducing physical disturbances, the present invention also takes into account environmental factors such as water quality and noise. The nozzle assembly 13 can be equipped with noise reduction and vibration reduction equipment to reduce noise pollution generated during the mining process. In addition, the water used in the water jet of the nozzle assembly 13 is treated and filtered to ensure that no harmful substances are introduced to protect the marine environment.

[0050] Therefore, the present design achieves the dual goals of efficient mining and environmental protection by combining the crushing roller 121 and the nozzle assembly 13. The water jet system not only improves mining efficiency, but also reduces damage to the seabed sediment layer and the ecosystem.

[0051] In some embodiments, the delivery pipe 134 has one end connected to the high-pressure water pump 131, and the other end of the delivery pipe 134 is disposed at one end of the third pipe 141 adjacent to the crushing assembly 12, and the other end of the delivery pipe 134 extends in a direction away from the crushing assembly 12, so that the delivery pipe 134 passes high-pressure water to the third pipe 141 to transport sediment. Specifically, Figure 5As shown, the inlet of the delivery pipe 134 can be connected to the outlet of the high-pressure water pump 131. The outlet of the delivery pipe 134 is penetrated at the left end of the third pipe 141 and is located inside the delivery pipe 134. The outlet of the third pipe 141 is set to the right, so that the high-pressure water flow sprayed from the third pipe 141 flows to the outlet of the third pipe 141. The high-pressure water flow not only helps to push the sediment, but also ensures that the water flow can effectively push the sediment, prevents the sediment from being blocked in the pipeline, and improves the transportation efficiency.

[0052] In some embodiments, the traveling assembly 11 includes a vehicle body 111 , a first wheel 112 , a second wheel 113 , an elastic member 114 and a transmission belt 115 .

[0053] The crushing assembly 12, the nozzle assembly 13 and the collecting assembly 14 are all arranged on the vehicle body 111. Specifically, Figure 1 As shown, the vehicle body 111 is made of high-strength, corrosion-resistant materials, has good pressure resistance, and can be used for a long time in a deep-sea environment. The crushing assembly 12, the nozzle assembly 13 and the collection assembly 14 are all installed on the vehicle body 111, thereby providing an installation basis for the crushing assembly 12, the nozzle assembly 13 and the collection assembly 14 through the vehicle body 111.

[0054] The first wheels 112 are rotatably disposed on the vehicle body 111 and are spaced apart along the direction of the vehicle body 111. Figure 2 As shown, the first wheel 112 is a driving wheel and there are multiple first wheels. A portion of the multiple first wheels 112 is arranged on the front side of the vehicle body 111 and is spaced apart along the left-right direction, and another portion of the multiple first wheels 112 is arranged on the rear side of the vehicle body 111 and is spaced apart along the left-right direction.

[0055] The second wheel 113 is rotatably disposed below the first wheel 112 and is spaced apart from the first wheel 112 in the vertical direction. The second wheel 113 is movable in the vertical direction relative to the first wheel 112. Figure 2 and Figure 3 As shown, there are multiple second wheels 113, a part of the multiple second wheels 113 is arranged on the front side of the vehicle body 111 and is spaced apart in the left-right direction and is located below the first wheel 112, and the first wheel 112 and the second wheel 113 are spaced apart in the up-down direction, another part of the multiple first wheels 112 is arranged on the rear side of the vehicle body 111 and is spaced apart in the left-right direction, and the first wheel 112 and the second wheel 113 are spaced apart in the up-down direction.

[0056] The elastic member 114 is disposed between the traveling assembly 11 and the second wheel 113 and is connected to the traveling assembly 11 and the second wheel 113 so that the elastic member 114 has a buffer force to drive the second wheel 113 to move downward. Figure 2As shown, the elastic member 114 is a spring, a hydraulic shock absorber, etc. The upper end of the elastic member 114 is connected to the vehicle body 111, and the lower end of the elastic member 114 is connected to the second wheel 113. Therefore, when the second wheel 113 encounters a protrusion or other obstacles, the elastic member 114 can absorb the impact energy and make the second wheel 113 move downward, thereby protecting the safety of the vehicle body 111 and various components, as well as the stability of the walking component 11.

[0057] The transmission belt 115 is sleeved on the first wheel 112 and the second wheel 113 so that the transmission belt 115 rotates through the first wheel 112 and the second wheel 113. The outer circumference of the transmission belt 115 has a plurality of protrusions 116, which are arranged at intervals along the circumference of the transmission belt 115. The cross-sectional area of ​​the protrusions 116 gradually decreases away from the outer circumference of the transmission belt 115. Specifically, as Figure 2 As shown, the transmission belt 115 is annular and is sleeved on the first wheel 112 and the second wheel 113. The transmission belt 115 is driven to move by the coordinated rotation of the first wheel 112 and the second wheel 113, and the outer peripheral surface of the transmission belt 115 has a plurality of protrusions 116 arranged at intervals along the circumference of the transmission belt 115, and its cross-sectional area gradually decreases along the outer peripheral surface away from the transmission belt 115, so that the friction between the transmission belt 115 and the seabed surface is increased by the protrusions 116, ensuring that the vehicle can still maintain good traction on a slippery or soft seabed surface, and the shape design of the protrusions 116 helps to discharge sediments mixed in the transmission belt 115, prevent blockage, and ensure the smooth operation of the transmission belt 115. At the same time, the design of the first wheel 112 and the second wheel 113 and the function of the elastic member 114 enhance the grip and stability of the vehicle to adapt to the complex and changeable seabed environment.
