[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] The deep-sea mining vehicle 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0027] like Figure 1-6 As shown, a deep-sea mining vehicle 100 according to an embodiment of the present invention includes a vehicle body 1 , a floating component 2 , an adjustment component 3 and a collection component 4 .

[0028] The vehicle body 1 is suitable for moving on the seabed. Figure 1 As shown, the vehicle body 1 can be made of high-strength, corrosion-resistant materials to ensure that the vehicle body 1 can operate reliably for a long time in a deep-sea environment with high pressure, low temperature and high salinity.

[0029] The floating assembly 2 is disposed on the vehicle body 1 and connected to the vehicle body 1, and the floating assembly 2 is used to provide buoyancy to the vehicle body 1. Specifically, Figure 4 As shown, the floating component 2 is arranged on the vehicle body 1 and connected to the vehicle body 1. The floating component 2 can accurately control the buoyancy of the vehicle body 1 to ensure that the mining vehicle maintains an appropriate suspension state at different depths of the seabed, reduce the pressure of the vehicle body 1 on the seabed surface, and avoid damaging the seabed ecosystem.

[0030] The adjustment component 3 is provided on the vehicle body 1, and the adjustment component 3 is used to adjust the posture and position of the vehicle body 1. Specifically, Figure 1As shown, the adjustment component 3 is arranged on the vehicle body 1, and the adjustment component 3 can adjust the posture (for example: movement angle) and position of the vehicle body 1 to ensure that the vehicle body 1 maintains a stable working posture in complex seabed terrain, and can accurately locate the target mining point, maintain the stability of the vehicle body 1, and improve work efficiency and safety.

[0031] The collecting assembly 4 includes a mounting frame 41, a first crushing member 42, a spraying member 43 and a collecting member 44. The mounting frame 41 is arranged on the vehicle body 1 and is arranged relative to the vehicle body 1 in the width direction of the vehicle body 1 (such as Figure 1 The first crushing member 42 is arranged on the mounting frame 41 and is rotatable relative to the mounting frame 41 in the width direction of the vehicle body 1, so that the first crushing member 42 crushes the seabed sediments. The ejecting member 43 and the collecting member 44 are both arranged on the mounting frame 41. The collecting member 44 is used to collect the crushed seabed sediments. The ejecting member 43 is used to eject the crushed seabed sediments so that the crushed seabed sediments are flushed into the collecting member 44, so that the collecting member 44 collects the crushed seabed sediments. Specifically, as Figure 1-Figure 5 As shown, the left end of the mounting frame 41 is hinged on the vehicle body 1 and rotates on the vehicle body 1 in the front-rear direction, so that the entire collection assembly 4 can adjust the angle as needed to approach the target mining point in the best posture. The first crushing member 42 is made of high-strength wear-resistant material to ensure that it can still work efficiently under high pressure and low temperature conditions. The first crushing member 42 is rotatable at the right end of the mounting frame 41. The injection member 43 and the collecting member 44 are arranged on the mounting frame 41 and on the left side of the first crushing member 42. When collecting, the mounting frame 41 drives the first crushing member 42 to move downward to contact the sediment on the seabed, and the motor drives the first crushing member 42 to rotate so that the first crushing member 42 crushes the sediment. The first crushing member 42 rotates clockwise and the vehicle body 1 moves to the right. When the inlet of the collecting member 44 moves to the top of the crushed sediment, the injection member 43 will spray high-pressure fluid (such as water or air) on the crushed sediment, so that the crushed sediment rushes up and rushes into the collecting member 44.

[0032] The deep-sea mining vehicle 100 of the embodiment of the present invention is provided with a vehicle body 1, a floating component 2, an adjustment component 3 and a collection component 4. The floating component 2 can adjust the buoyancy in real time according to the seabed conditions to ensure the operation stability of the vehicle in different deep-sea environments. The adjustment component 3 can adjust the posture and position of the vehicle body 1 in real time to ensure the efficient operation of the vehicle body 1. The first crushing component 42 can achieve precise excavation and cleaning to reduce disturbance to non-target areas. The injection component 43 ensures that water flow impact is only performed in necessary areas to protect the surrounding seabed ecology, improve the collection efficiency, and reduce the damage to the seabed ecosystem, thereby achieving a more environmentally friendly mining method.

[0033] In some embodiments, the floating assembly 2 includes a floating box 21, which is disposed on the vehicle body 1 and is suitable for introducing air and seawater to adjust the buoyancy of the floating box 21. Specifically, Figure 4 As shown, the floating box 21 is provided with an air pipe and a valve system, and air can be filled into the floating box 21 through the control system. The introduction of air will increase the buoyancy of the floating box 21, so that the mining vehicle can rise or remain at a higher position, and the floating box 21 is also equipped with a water inlet and a drain, and seawater can be injected into or discharged from the floating box 21 as needed. By controlling the inflow and outflow of seawater, the weight of the floating box 21 can be accurately adjusted, and then the buoyancy can be adjusted to make the mining vehicle sink or remain at a lower position. Therefore, the floating box 21 can achieve precise buoyancy adjustment by introducing air and seawater, ensuring that the mining vehicle can maintain a stable posture and position under different depths and terrain conditions, so that the mining vehicle can move flexibly in a complex seabed environment and adapt to changing working conditions, reducing the operational risks caused by depth changes, improving the safety and reliability of the entire system, and reducing unnecessary up and down floating, improving work efficiency, and extending the operation time of each dive.

[0034] In some embodiments, there are multiple floating boxes 21, and the multiple floating boxes 21 are all arranged on the vehicle body 1 and are arranged in sequence along the width direction of the vehicle body 1. Figure 4 As shown, there are two floating boxes 21, which are respectively fixed on the vehicle body 1 and symmetrically arranged in the left-right direction. The two floating boxes 21 can ensure that the buoyancy is more evenly distributed on the vehicle body 1, help maintain the horizontal posture of the vehicle body 1, and avoid the center of gravity shift problem caused by a single large floating box 21. The two floating boxes 21 can adjust the ratio of internal air and seawater according to actual needs, flexibly adjust the overall buoyancy, and ensure that the vehicle is always in the best working condition. In addition, if one of the floating boxes 21 fails or is damaged, the other floating box 21 can still provide the necessary buoyancy to ensure that the vehicle will not immediately lose buoyancy and sink to the bottom of the sea, thereby improving the reliability and safety of the deep-sea mining vehicle 100.

[0035] In some embodiments, the first crushing member 42 includes a rotating drum 421 and a plurality of crushing units 422 .

[0036] The rotating cylinder 421 is disposed on the mounting frame 41 and is rotatable relative to the mounting frame 41 around the width direction of the vehicle body 1. The rotating cylinder 421 is detachably disposed on the mounting frame 41 so as to replace the rotating cylinder 421. Figure 2 and Figure 5As shown, the rotating cylinder 421 is rotatably disposed on the right end of the mounting frame 41, and a motor can be disposed on the rotating cylinder 421 to drive the rotating cylinder 421 to rotate on the mounting frame 41. The rotating cylinder 421 is detachably disposed on the mounting frame 41, so that the structure of the first crushing component 42 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 first crushing component 42.

[0037] The crushing unit 422 is pick-shaped, and a plurality of crushing units 422 are arranged on the rotating cylinder 421 and are arranged in a plurality of rows along the axial direction of the rotating cylinder 421, and each row includes a plurality of crushing units 422 arranged along the circumferential direction of the rotating cylinder 421. Specifically, Figure 6 As shown, the crushing unit 422 is a pick-shaped tool. In other words, the crushing unit 422 has a sharp front end and a back. The sharp front end is suitable for efficiently crushing seabed sediments. The back of the crushing unit 422 can be fixed on the rotating cylinder 421. Multiple crushing units 422 are arranged in multiple rows along the front-to-back direction, and each row includes a plurality of crushing units 422 arranged at intervals along the circumference of the rotating cylinder 421, so that the crushing units 422 can be evenly distributed in the rotating cylinder 421, so that the seabed sediments can be crushed in an all-round and multi-level manner to adapt to various seabed geological conditions. In addition, when the rotating cylinder 421 starts to rotate, the sharp front end of the pick-shaped tool first penetrates into the seabed sediment layer to separate the ore from the surrounding mud and sand, and can effectively lift the ore from the sediment layer, reducing the resistance and energy consumption during the excavation process. The continuously rotating rotating cylinder 421 can maintain an efficient working rhythm during the excavation process, so that the ore can be quickly excavated. The crushing efficiency of the first crushing element 42 is guaranteed, and both soft mud and hard rock can be effectively crushed, thereby improving the application range of the equipment.

[0038] In some embodiments, a plurality of mounting seats 423 are provided on the rotating drum 421, and the plurality of mounting seats 423 are detachably connected to the plurality of crushing units 422 in a one-to-one correspondence. Figure 6 As shown, the number of mounting seats 423 is equal to the number of crushing units 422, and a crushing unit 422 can be set on each mounting seat 423, and the crushing unit 422 is detachably installed in the mounting seat 423 through threaded connections or fasteners, so that when one of the crushing units 422 is damaged, it can be replaced or maintained, which reduces maintenance cost and time, reduces maintenance costs, and improves maintenance efficiency.

[0039] In some embodiments, the collecting member 44 includes a collecting pipe, one end of which is fixed on the vehicle body 1 and is suitable for being connected to a pump, the collecting pipe extends in a direction away from the vehicle body 1 and is inclined from top to bottom, the other end of the collecting pipe is located between the vehicle body 1 and the first crushing member 42 and one end of the collecting pipe is arranged downward, and in a projection plane orthogonal to the length direction of the vehicle body 1, the other end of the collecting pipe is located above the first crushing member 42, and the ejection member 43 is arranged on the other end of the collecting pipe so that the ejection member 43 flushes the crushed seabed sediment into the collecting pipe. Specifically, as Figure 2 and Figure 3 As shown, the outlet of the collecting pipe is fixed on the vehicle body 1 and can be connected to the pump. The collecting pipe extends from left to right and tilts from top to bottom, and the inlet of the collecting pipe is set downward. The collecting pipe is located between the vehicle body 1 and the first crushing member 42, and the inlet of the collecting pipe is located on the left side of the first crushing member 42 and above the first crushing member 42. The injection member 43 is arranged at the inlet of the collecting pipe and is adjacent to the working area of ​​the first crushing member 42. Therefore, when the first crushing member 42 (rotating cylinder 421 and pick-shaped crushing unit 422) crushes the seabed sediment, the crushed material will naturally fall to the bottom of the collecting pipe. At this time, the injection member 43 is started, and the crushed materials are flushed into the collecting pipe by high-pressure water flow or air flow to ensure that they smoothly enter the subsequent processing system, so that the design of the collecting pipe and the injection member 43 is closely matched to form an efficient collection system, so that the three steps of crushing, flushing and collecting are seamlessly connected to ensure the continuity and efficiency of the entire mining process.

[0040] It is worth noting that a collecting bin (not shown in the figure) may be provided on the vehicle body 1 , and the collecting bin is connected to the collecting member 44 , so that the seabed sediments are collected into the collecting bin through the collecting member 44 .

[0041] In some embodiments, the injection member 43 includes a first injection member 431 and a second injection member 432 .

[0042] The first injection member 431 includes a first injection pipe 4311 and a first nozzle 4312. The first injection pipe 4311 can be filled with high-pressure water and is connected to the first nozzle 4312. The first nozzle 4312 is arranged on a side of the collecting pipe adjacent to the first crushing member 42. The first nozzle 4312 extends from top to bottom and is inclined toward a side away from the first crushing member 42. Specifically, as Figure 2As shown, the first nozzle 4312 is made of high pressure resistant and corrosion resistant materials to ensure that it is not easily damaged in long-term use in a deep sea environment. The inlet of the first injection pipe 4311 can be connected to a water pump. There are multiple first nozzles 4312, and the multiple first nozzles 4312 are sequentially arranged on the right side of the outlet of the collecting pipe along the front-to-back direction. The first nozzles 4312 extend from top to bottom and tilt to the left. The multiple first nozzles 4312 are all connected to the first injection pipe 4311, so that the injection water is ejected through the first injection pipe 4311 through the first nozzles 4312. The first nozzles 4312 are connected to the first injection pipe 4311, and the first nozzles 4312 are connected to the first injection pipe 4311. The setting of the head 4312 can make the water flow tilted to the left, and the angle and spray force of the first nozzle 4312 can be adjusted to adapt to different types of sedimentary layers and ore densities. The first nozzle 4312 can also accurately control the impact force by adjusting the water pressure and the spray 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 4312, the 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.

[0043] The second injection member 432 includes a second injection pipe 4321 and a second nozzle 4322. The second injection pipe 4321 can be filled with high-pressure water and is connected to the second nozzle 4322. The second nozzle 4322 is arranged on a side of the collecting pipe away from the first crushing member 42. The second nozzle 4322 extends from top to bottom and is inclined toward a side adjacent to the first crushing member 42. Specifically, Figure 2 As shown, the inlet of the second injection pipe 4321 can be connected to a water pump, there are multiple second nozzles 4322, and the multiple second nozzles 4322 are sequentially arranged on the left side of the outlet of the collecting pipe along the front-to-back direction. The second nozzle 4322 extends from top to bottom and tilts to the right. The multiple second nozzles 4322 are all connected to the second injection pipe 4321, so that the injection water is ejected through the second injection pipe 4321 through the second nozzle 4322. The setting of the second nozzle 4322 can make the water flow tilted to the right. The reverse water flow generated by the second nozzle 4322 forms a "water wall", which effectively prevents the ore from scattering backwards, so that the ore is concentrated near the rotating cylinder 421 for easy collection, and the confluence of the first nozzle 4312 and the second nozzle 4322 forms an upward thrust, which lifts the ore and guides it to the inlet of the collecting pipe, ensuring that the ore can be smoothly transported to the collecting pipe. In addition, the high-pressure water jets ejected by the first ejection member 431 and the second ejection member 432 are not only used to lift and guide the ore, but also can quickly clean the mud and sediment on the surface of the rotating drum 421, reduce the friction between the rotating drum 421 and the ore, and improve work efficiency. Through the flushing of the high-pressure water flow, the rotating drum 421 can be kept clean and avoid jamming and wear caused by mud and sand accumulation.

[0044] The present invention implements the deep-sea mining vehicle 100 through the arrangement of the first crushing member 42 and the injection member 43, which has the following advantages: 1. Reduce disturbance: The first crushing member 42 is mainly responsible for the excavation task, and the high-pressure water jet of the injection member 43 is used as an auxiliary tool to reduce the direct impact of the water jet on the sediment layer. The ore excavated by the first crushing member 42 is cleaned and guided by the water jet, which can better control the impact on the seabed sediments.

[0045] 2. Precise operation: Through the coordinated work of the machine (first crushing element 42) and the water jet (injection element 43), precise excavation and cleaning can be achieved, reducing disturbance to non-target areas. The reasonable configuration of the front and rear rows of jets ensures that water flow impact is only carried out in necessary areas to protect the surrounding seabed ecology.

[0046] 3. Reduce ecological damage: Pure water jet mining systems often cause a large amount of sediment to suspend, affecting the seabed ecosystem. By combining mechanical excavation and water jets, this design can reduce the scope of sediment suspension and diffusion, and reduce damage to the seabed ecological environment.

[0047] 4. Sediment control: The jet element 43 may be designed with a multi-stage filtering and regulating function, 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.

[0048] 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 jet 43 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 jet 43 is treated and filtered to ensure that no harmful substances are introduced to protect the marine environment.

[0049] Therefore, the present design achieves the dual goals of efficient mining and environmental protection by combining the first crushing element 42 and the jet element 43. The water jet system not only improves mining efficiency, but also reduces damage to the seabed sediment layer and the ecosystem.

[0050] In some embodiments, the collecting member 44 further includes a delivery pipe 45, one end of which is suitable for passing high-pressure water, and the other end of the delivery pipe 45 is arranged at one end of the collecting pipe adjacent to the first crushing member 42, and the other end of the delivery pipe 45 extends in a direction away from the first crushing member 42, so that the delivery pipe 45 passes high-pressure water to the collecting pipe to transport the sediment. Specifically, Figure 3 As shown, the inlet of the delivery pipe 45 can be connected to the water pump, the outlet of the delivery pipe 45 is passed through the right end of the collecting pipe and is located inside the delivery pipe 45, and the outlet of the collecting pipe is set to the left, so that the high-pressure water flow sprayed from the collecting pipe flows to the outlet of the collecting pipe. The high-pressure water flow not only helps to push the sediment, but also ensures that the water flow can effectively push the sediment, prevent the sediment from being blocked in the pipeline, and improve the transportation efficiency.

[0051] In some embodiments, the adjustment assembly 3 includes a first propeller 31 , a second propeller 32 and a first detection member (not shown in the figure).

[0052] The first propeller 31 and the second propeller 32 are both rotatably disposed on the vehicle body 1 and are spaced apart from each other in the width direction of the vehicle body 1. The first propeller 31 and the second propeller 32 are used to adjust the posture and position of the vehicle body 1. Specifically, Figure 3 As shown, the first propeller 31 and the second propeller 32 are fixed to the vehicle body 1 through a solid bracket or shaft connecting member, and the first propeller 31 and the second propeller 32 are arranged relative to each other in the front-to-back direction to ensure that they remain stably connected under high pressure, and the first propeller 31 and the second propeller 32 can be driven by a motor, so that by adjusting the rotation speed and rotation direction of the first propeller 31 and the second propeller 32, the vehicle body 1 can be fine-tuned in the horizontal and vertical directions to ensure that the vehicle can accurately reach the predetermined position and remain stable, or adjust the posture of the vehicle body 1 ( Such as pitch angle, roll angle and yaw angle), to ensure that the vehicle maintains stability and the correct direction of travel in a complex seabed environment. In addition, the first propeller 31 and the second propeller 32 can work individually or simultaneously as needed to achieve more precise attitude and position adjustment. For example, when the roll angle needs to be adjusted, the propeller on one side (for example: the first propeller 31) may increase the thrust, while the propeller on the other side (for example: the second propeller 32) reduces the thrust; when the yaw angle needs to be adjusted, the first propeller 31 and the second propeller 32 can rotate in opposite directions to generate a steering torque.

[0053] In some embodiments, the first detection member is used to detect that when the posture and position of the vehicle body 1 deviate from the preset value, at least one of the first propeller 31 and the second propeller 32 works. Specifically, the first detection member can be a sensor, and the first detection member includes but is not limited to an attitude angle sensor, a position sensor, and an acceleration sensor. The first detection member continuously monitors the posture and position data of the vehicle body 1 and sends it to the control system. If a deviation is detected, the control system will calculate the required adjustment amount according to the algorithm, and instruct the corresponding first propeller 31 and the second propeller 32 to start or change the speed to correct the deviation, and adjust the posture and position of the vehicle body 1 by turning on at least one of the first propeller 31 and the second propeller 32. For example, when the vehicle body 1 tilts forward, the thrust of the first propeller 31 on the front side is increased or the thrust of the second propeller 32 on the rear side is reduced to restore the balance of the vehicle body 1.

[0054] In some embodiments, the deep-sea mining vehicle 100 further includes a second crushing member 5, which includes a shell 51 and a crushing roller 52. The shell 51 is disposed on the vehicle body 1 and is connected to the collecting member 44 so that the sediment collected by the collecting member 44 can be transported to the crushing roller 52. The crushing roller 52 is rotatably disposed in the shell 51 so as to crush the sediment. Specifically, Figure 1 and Figure 3 As shown, the housing 51 is arranged above the vehicle body 1 and a crushing chamber can be formed in the housing 51. The crushing roller 52 is rotatably arranged in the housing 51 and driven by a motor. The crushing roller 52 is provided with a protrusion and a tooth structure to enhance the crushing effect, so that the crushing roller 52 applies shear force and impact force to the sediment during rotation to crush it into smaller particles. The housing 51 can be connected with the outlet of the collection pipe and the inlet of the collection bin, so that the crushing roller 52 can crush the sediment. Thus, the collected seabed sediment is preliminarily crushed and refined by the second crushing element 5, and the larger pieces of sediment are crushed into smaller and more uniform particles, which are convenient for subsequent processing and transportation. In addition, the crushed sediment is easier to be further processed (such as screening, separation, etc.), which improves the efficiency of the entire mining process. Smaller particles are also easier to transport and store, reducing the risk of equipment blockage.

[0055] In some embodiments, the crushing roller 52 is detachably disposed in the housing 51 to facilitate replacement of the crushing roller 52. Thus, the crushing roller 52 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 52.

[0056] In some embodiments, the vehicle body 1 includes a vehicle body 11, a first wheel 12, a second wheel 13, a buffer 14, and a transmission belt 15. The floating component 2, the adjusting component 3 and the collecting component 4 are all arranged on the vehicle body 11. Specifically, Figure 1 As shown, the vehicle body 11 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 floating component 2, the adjustment component 3 and the collection component 4 are all installed on the vehicle body 11, providing an installation basis for the floating component 2, the adjustment component 3 and the collection component 4.

[0057] The first wheels 12 are rotatably disposed on the vehicle body 11 and are spaced apart along the direction of the vehicle body 11. Specifically, Figure 2 As shown, the first wheel 12 is a driving wheel and there are multiple first wheels. A portion of the multiple first wheels 12 is arranged on the front side of the vehicle body 11 and is spaced apart along the left-right direction, and another portion of the multiple first wheels 12 is arranged on the rear side of the vehicle body 11 and is spaced apart along the left-right direction.

[0058] The second wheel 13 is rotatably disposed below the first wheel 12 and spaced apart from the first wheel 12 in the vertical direction. The second wheel 13 is movable in the vertical direction relative to the first wheel 12. Figure 2 and Figure 3As shown, there are multiple second wheels 13, a part of the multiple second wheels 13 is arranged on the front side of the vehicle body 11 and is spaced apart in the left-right direction and is located below the first wheel 12, and the first wheel 12 and the second wheel 13 are spaced apart in the up-down direction, another part of the multiple first wheels 12 is arranged on the rear side of the vehicle body 11 and is spaced apart in the left-right direction, and the first wheel 12 and the second wheel 13 are spaced apart in the up-down direction.

[0059] The buffer member 14 is disposed between the vehicle body 1 and the second wheel 13 and is connected to the vehicle body 1 and the second wheel 13 so that the buffer member 14 has a buffer force to drive the second wheel 13 to move downward. Figure 2 As shown, the buffer 14 is a spring, a hydraulic shock absorber, etc. The upper end of the buffer 14 is connected to the vehicle body 11, and the lower end of the buffer 14 is connected to the second wheel 13. Therefore, when the second wheel 13 encounters a bump or other obstacle, the buffer 14 can absorb the impact energy and make the second wheel 13 move downward, thereby protecting the safety of the vehicle body 11 and various components, as well as the stability of the vehicle body 1 when walking.

[0060] The transmission belt 15 is sleeved on the first wheel 12 and the second wheel 13 so that the transmission belt 15 rotates through the first wheel 12 and the second wheel 13. The outer circumference of the transmission belt 15 has a plurality of protrusions 151, which are arranged at intervals along the circumference of the transmission belt 15. The cross-sectional area of ​​the protrusions 151 gradually decreases away from the outer circumference of the transmission belt 15. Specifically, as Figure 2 As shown, the transmission belt 15 is annular and is sleeved on the first wheel 12 and the second wheel 13. The transmission belt 15 is driven to move by the coordinated rotation of the first wheel 12 and the second wheel 13, and the outer peripheral surface of the transmission belt 15 has a plurality of protrusions 151 arranged at intervals along the circumference of the transmission belt 15, and its cross-sectional area gradually decreases along the outer peripheral surface away from the transmission belt 15, so that the friction between the transmission belt 15 and the seabed surface is increased by the protrusions 151, ensuring that the vehicle can still maintain good traction on a slippery or soft seabed surface, and the shape design of the protrusions 151 helps to discharge sediments mixed in the transmission belt 15, prevent blockage, and ensure the smooth operation of the transmission belt 15. At the same time, the design of the first wheel 12 and the second wheel 13 and the function of the buffer 14 enhance the grip and stability of the vehicle to adapt to the complex and changeable seabed environment.

[0061] The deep-sea mining vehicle 100 further includes a control component (not shown in the figure), which is connected to the floating component 2, the adjustment component 3 and the collection component 4 respectively, so that the control component controls the adjustment component 3 to adjust the posture and position of the vehicle body 1 through the buoyancy change of the floating component 2 and the collection situation of the collection component 4, or the control component controls the jet intensity and injection angle of the injection component 43, so as to reduce the suspension of sediments and control the diffusion range. Specifically, the control component is a controller, which is closely connected with the floating component 2, the adjustment component 3 and the collection component 4 through the connecting line, forming a closed-loop control system, so that the control component can receive feedback information from the floating component 2, the adjustment component 3 and the collection component 4 in real time, and respond quickly and accurately according to the information, for example: the control component comprehensively judges the current working state of the deep-sea mining vehicle 100 according to the buoyancy change data provided by the floating component 2 and the collection situation fed back by the collection component 4. When a deviation or adjustment is detected, the control component will immediately start the adjustment component 3, and optimize the posture and position of the vehicle body 1 through precise adjustment to ensure that the vehicle can perform the mining task stably and efficiently.

[0062] The control component also has the ability to finely control the jet element 43, and can flexibly adjust the jet intensity and jet angle of the jet element 43 according to actual needs. Thus, through precise jet control, the deep-sea mining vehicle 100 can achieve efficient and environmentally friendly mining operations without destroying the seabed ecological environment.

[0063] The deep-sea mining vehicle 100 also includes a second detection component (schematically shown in the figure), which is arranged on the outer peripheral side of the vehicle body so that the second detection component monitors the water flow velocity, terrain changes and ore density around the vehicle body to adjust the floating component 2, the adjustment component 3 and the collection component 4. Specifically, the second detection component includes a flow rate sensor, a terrain sensor and a stone density sensor, and the flow rate sensor, the terrain sensor and the stone density sensor are all arranged on the outer peripheral side of the vehicle body, so that key data such as water flow velocity, terrain changes and ore density can be monitored in real time. Therefore, through the monitoring of the second detection component, the speed and direction of the water flow around the vehicle body 1 can be understood in real time, so as to adjust the buoyancy output of the floating component 2 in time, ensure that the vehicle body 1 maintains a stable posture and position in a complex water flow environment, help reduce the interruption of operations caused by water flow impact, and improve the continuity and stability of mining operations.

[0064] In addition, the second detection component can accurately identify the ups and downs and changes in the seabed terrain, and provide accurate terrain data for the adjustment component 3, so that the vehicle body 1 can flexibly adjust its route and operating posture to adapt to mining needs under different terrain conditions, helping to reduce the difficulty of operation and improve mining efficiency and safety.

[0065] Finally, the second detection component can provide accurate collection guidance for the collection component 4 by real-time monitoring of ore density. When a high-density ore area is detected, the vehicle body 1 can automatically adjust the working state of the collection component 4 to improve the collection efficiency and ore recovery rate. At the same time, by monitoring the changes in ore density, the vehicle body 1 can also promptly discover potential mineral resources and provide strong support for subsequent mining operations.

[0066] According to the following Figure 1-Figure 6 The deep-sea mining vehicle 100 according to the embodiment of the present invention is specifically described.

[0067] like Figures 1 to 6 As shown, this specification provides a new deep-sea environment-friendly multifunctional mining vehicle including: a body 11, a track system (the track system includes a first wheel 12, a second wheel 13, a buffer 14, a transmission belt 15 and a protrusion 151), an adjustment component, a collection component 4 and a floating component 2.

[0068] The body 11 is made of high-strength aluminum alloy material, which can provide sufficient strength and stability in the deep-sea high-pressure environment. The aluminum alloy material has excellent corrosion resistance and can resist seawater corrosion, thereby improving the durability of the equipment. The structural design of the body 11 takes into account the influence of underwater high pressure and depth, and adopts a closed frame structure to increase the overall strength, reduce deformation, and improve the operating stability of the equipment.

[0069] The body 11 is the supporting structure of the entire mining vehicle, on which the hydraulic motor crawler system and other functional modules are arranged. The body 11 has a high-strength structural design and is suitable for stable operation in a deep-sea high-pressure environment.

[0070] The body 11 supports all structural components of the entire mining vehicle and ensures the mechanical connection between the functional modules. The hydraulic motor and the track system are fixed to the body 11 to provide power and stable support for the movement of the vehicle. The protrusion 151 of the transmission belt 15 is designed to disperse the ground pressure to prevent it from sinking in the soft mud terrain. At the same time, it is equipped with an automatic adjustment function to adapt to different changes in the seabed terrain. The crawler system includes a first wheel 12, a second wheel 13, a buffer 14, and a transmission belt 15. The hydraulic motor drives the first wheel 12 to achieve efficient obstacle crossing and flexible movement of the vehicle. The transmission belt 15 is designed to effectively disperse the ground pressure, reduce the risk of the equipment sinking into the mud, and has an automatic adjustment function to adapt to different seabed terrains.

[0071] The transmission belt 15 is made of a mixture of highly wear-resistant rubber and steel, which is corrosion-resistant and has good flexibility. The design of the first and second steel wheels 12 and 13, as well as the buffer 14, enables the track system to adapt to complex seabed terrain. The buffer 14 can absorb the vibration caused by the terrain to the mining trolley during the movement of the trolley, reduce the stress on the track, and make the track system more stable and reliable.

[0072] Adjustment components ( Figure 3 ) The first propeller 31 and the second propeller 32 are used to realize precise positioning and attitude adjustment of the vehicle in a complex seabed environment. The first propeller 31 and the second propeller 32 are combined with the vehicle body 1, and the thrust and direction of the propellers are adjusted in real time through the electro-hydraulic control system to ensure the operation stability of the vehicle under the interference of strong ocean currents.

[0073] The first propeller 31 and the second propeller 32 are mainly made of high-strength alloy steel, which has excellent corrosion resistance and durability. The first propeller 31 and the second propeller 32 are compactly designed and can be accurately positioned under strong ocean current conditions. The use of the electro-hydraulic control system allows the thrust and direction of the first propeller 31 and the second propeller 32 to be adjusted in real time through the control system, ensuring the stability of the vehicle in the complex seabed environment.

[0074] The positioning and posture of the vehicle are precisely controlled by the first propeller 31 and the second propeller 32, so that it can operate stably in a high-velocity and high-fluctuation seabed environment. The thrust and direction of the first propeller 31 and the second propeller 32 can be adjusted in real time through the electro-hydraulic control system, ensuring that the vehicle can still accurately control the operating position and reduce drift in the case of large sea currents and water flow interference.

[0075] The first crushing component 42 and the injection component 43 are the main operating modules of the mining vehicle, including a rotating cylinder 421, a crushing unit 422, a first nozzle 4312, a first injection pipe 4311, a second injection pipe 4321, a second nozzle 4322 and a high-pressure water pump. The first crushing component 42 can efficiently crush the seabed sediments, and the injection component 43 sprays high-pressure water flow into the crushing area to assist in loosening and transporting the sediments. The jet system is designed with low disturbance and high efficiency, effectively reducing the diffusion of suspended particles in the sediment layer.

[0076] The rotating cylinder 421 is made of high-strength steel and corrosion-resistant alloy materials, and the surface is specially treated to enhance wear resistance. The first nozzle 4312, the first injection pipe 4311, the second injection pipe 4321, and the second nozzle 4322 are all made of corrosion-resistant stainless steel, which can resist the corrosion of seawater. The high-pressure water pump is made of special rubber material with high strength and high pressure resistance.

[0077] The first crushing element 42 scrapes and crushes the seabed sediments by rotation, ensuring that the hardened sediments can be effectively crushed and loosened in complex terrain, and the conveying pipe 45 conveys the crushed materials to the mining pump system of the trolley. The ejection element 43 can assist in the loosening of sediments under low disturbance conditions to avoid further damage to the seabed ecological environment.

[0078] The floating box 21 provides additional buoyancy support to reduce the pressure of the transmission belt 15 on the mud surface. The buoyancy box 42 provides additional buoyancy support, which reduces the pressure of the trolley on the seabed terrain, helps to avoid sinking into the mud, and maintains the operation stability of the trolley. The ore delivery riser can be connected to the collection component 4 through the ore delivery pump, and the ore and sediment mixture can be transported to the sea surface through the high-efficiency pumping system. The ore pump and the ore delivery riser are made of high-strength stainless steel material with excellent corrosion resistance and pressure resistance. The material of the buoyancy box is a lightweight high-strength alloy, which can provide additional buoyancy support and reduce the pressure of the crawler system on the mud surface.

[0079] In addition, the mining vehicle is equipped with multifunctional auxiliary devices, including searchlight 6 for deep-sea operation lighting, electric control cabinet for centralized control of various systems, and second crushing unit 5 for further crushing of large sediments. The coordinated operation of these functional modules ensures the efficient operation capability and environmental friendliness of the mining vehicle.

[0080] The searchlight 6 uses a high-intensity LED light source with low power consumption and high brightness, which can provide stable deep-sea operation lighting. The electric control cabinet uses anti-corrosion materials and integrates the control units of various systems to ensure the coordinated operation of the mining vehicle. The second crushing part 5 is made of high-strength steel with excellent wear resistance and compression resistance, which can further crush larger sediments.

[0081] The coordinated operation of these auxiliary devices enables the mining vehicle to operate efficiently in the complex deep-sea environment while reducing environmental damage. The searchlight 6 ensures the field of vision in the dark seabed environment, and the electric control cabinet provides coordinated control between systems to ensure the smooth operation of each functional module. The second crushing unit 5 further processes large pieces of sediment to reduce the impact of sediment on the environment.

[0082] The deep-sea mining vehicle 100 of the embodiment of the present invention has the following beneficial effects: Efficient mining: The present invention adopts a mining method combining the first crushing member 42 and the ejection member 43. The first crushing member 42 is responsible for crushing hard ore, and the ejection member 43 is used to clean the mining area and guide the ore to the collection member 44. This combination method significantly improves the mining efficiency, especially in the seabed environment with alternating soft and hard seabeds, and can effectively cope with the changes in ore properties and realize continuous and efficient mining operations.

[0083] Strong stability: The present invention uses the coordinated design of the crawler system and the floating component 2, and the transmission belt 15 is made of a rubber material with high teeth close to the involute line, combined with a double floating suspension and a lateral swing beam structure, which effectively improves the vehicle's grip and obstacle-crossing ability. The floating component 2 can adjust the buoyancy in real time according to the seabed conditions to ensure the vehicle's operating stability in different deep-sea environments, especially in steep slopes, soft mud and irregular terrain, with significant anti-slip and anti-overturning capabilities.

[0084] Environmental protection: The present invention focuses on reducing disturbance to the seabed ecology during the design process. By optimizing the flow rate and velocity of water jets, the disturbance of the sediment layer is reduced, and the diffusion effect of suspended sediments on the surrounding environment is reduced. At the same time, the overall structural design of the equipment avoids excessive damage to the original form of the seabed and reduces damage to the seabed ecosystem, thereby achieving a more environmentally friendly mining method.

[0085] Easy to operate: The trolley system of the present invention integrates multiple functional modules, including data transmission and remote control system, electro-hydraulic proportional control system, etc. The operator can accurately control the trolley through the real-time communication module. At the same time, the addition of the automatic adjustment function greatly reduces the need for manual intervention, making the operation of the equipment simpler and more efficient, and even in complex deep-sea working conditions, high-precision operation can be easily achieved.

[0086] Operational reliability: The present invention has designed multiple redundant protection mechanisms, such as the automatic thrust direction adjustment function in the dynamic positioning propeller system, the overload protection mechanism of the electro-hydraulic proportional control, and the dual system switching function of the crawler system and the mining pump. These designs have greatly improved the reliability of the system in extreme deep-sea environments, ensuring that the equipment can operate stably and efficiently under high pressure, low temperature and long-term operation conditions.

[0087] In summary, the new deep-sea mining vehicle 100 provided in this application can not only meet the operational needs in the complex deep-sea environment, but also take into account the operational characteristics of high efficiency, stability and environmental protection, and has broad application prospects and significant technical advantages.
