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

[0003] Among related technologies, mining methods can achieve a certain degree of resource extraction, but they are highly destructive to the environment and have low extraction efficiency. Utility Model Content

[0004] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0005] Among related technologies, mining methods suffer from the following main problems: They cause significant disturbance to sediment layers. While waterjet mining utilizes high-pressure water jets for excavation and transport, it leads to the suspension of large amounts of sediment, creating high-concentration turbidity zones that have long-term impacts on the stability of the seabed ecosystem. For example, benthic organisms may gradually die out due to habitat loss, thus disrupting the seabed ecological balance. Poor stability: Traditional equipment lacks stability in navigating and operating on complex seabed terrain. Common problems include slippage, yaw, and capsizing, which significantly reduces mining efficiency and increases operating costs.

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following description, with reference to the accompanying drawings, describes a deep-sea mining apparatus 100 according to an embodiment of the present invention.

[0028] like Figure 1-6 As shown, the deep-sea mining device 100 according to an embodiment of the present invention includes a vehicle body 1, a floating assembly 2, an adjustment assembly 3, and a collection assembly 4.

[0029] The vehicle body 1 is adapted for movement within the seabed. Specifically, as... 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 the deep-sea environment with high pressure, low temperature and high salinity.

[0030] The floating component 2 is mounted on and connected to the vehicle body 1, and is used to provide buoyancy to the vehicle body 1. Specifically, as follows: Figure 4 As shown, the floating component 2 is located on the vehicle body 1 and connected to the vehicle body 1. The buoyancy of the vehicle body 1 can be precisely controlled through the floating component 2, ensuring that the mining trolley maintains an appropriate suspension state at different depths of the seabed, reducing the pressure of the vehicle body 1 on the seabed surface, and avoiding damage to the seabed ecosystem.

[0031] Adjustment component 3 is mounted on vehicle body 1 and is used to adjust the attitude and position of vehicle body 1. Specifically, as shown... Figure 1As shown, the adjustment component 3 is installed on the vehicle body 1. The adjustment component 3 can adjust the attitude (e.g., movement angle) and position of the vehicle body 1 to ensure that the vehicle body 1 maintains a stable working attitude 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.

[0032] The collection component 4 includes a mounting frame 41, a first fragmentation component 42, a spray component 43, and a collection component 44. The mounting frame 41 is mounted on the vehicle body 1 and is positioned relative to the vehicle body 1 in the width direction around the vehicle body 1 (e.g., ...). Figure 1 The first crusher 42 (shown in the front-to-back direction) is rotatable. It is mounted 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 crusher 42 crushes the seabed sediment. The spraying element 43 and the collecting element 44 are both mounted on the mounting frame 41. The collecting element 44 is used to collect the crushed seabed sediment, and the spraying element 43 is used to spray the crushed seabed sediment so that it is flushed into the collecting element 44, allowing the collecting element 44 to collect the crushed seabed sediment. Specifically, as shown... Figures 1-5 As shown, the left end of the mounting frame 41 is hinged to the vehicle body 1 and rotates around the front and rear directions on the vehicle body 1, so that the entire collection assembly 4 can be adjusted in angle as needed to approach the target mineral point in the best posture. The first crushing component 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 component 42 is rotatably located at the right end of the mounting frame 41. The spray component 43 and the collection component 44 are located on the mounting frame 41 and to the left of the first crushing component 42. When the collection work is carried out, the mounting frame 41 drives the first crushing component 42 to move downward to contact the sediment on the seabed. The motor drives the first crushing component 42 to rotate so that the first crushing component 42 crushes the sediment. The first crushing component 42 rotates clockwise and the vehicle body 1 moves to the right. When the inlet of the collection component 44 moves above the crushed sediment, the spray component 43 will spray high-pressure fluid (such as water or air) onto the crushed sediment, so that the crushed sediment is flushed up and rushes into the collection component 44.

[0033] The deep-sea mining device 100 of this utility model embodiment includes 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 stability of the vehicle in different deep-sea environments. The adjustment component 3 can adjust the attitude 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, reducing disturbance to non-target areas. The jetting component 43 ensures that water flow impact is only carried out in necessary areas, protecting the surrounding seabed ecology, improving collection efficiency, reducing damage to the seabed ecosystem, and thus achieving a more environmentally friendly mining method.

[0034] In some embodiments, the flotation assembly 2 includes a floatation box 21, which is mounted on the vehicle body 1 and is adapted to allow air and seawater to be introduced in order to adjust the buoyancy of the floatation box 21. Specifically, as Figure 4 As shown, the floating box 21 is equipped with an air pipe and valve system. Air can be introduced into the floating box 21 through the control system. The introduction of air increases the buoyancy of the floating box 21, allowing the mining trolley to rise or remain at a higher position. The floating box 21 is also equipped with a water inlet and a water outlet, allowing seawater to be injected or discharged into the floating box 21 as needed. By controlling the amount of seawater entering and leaving the floating box 21, the weight of the floating box 21 can be precisely adjusted, thereby adjusting the buoyancy and allowing the mining trolley to sink or remain at a lower position. Thus, by introducing air and seawater, the floating box 21 can achieve precise buoyancy adjustment, ensuring that the mining trolley maintains a stable attitude and position under different depths and terrain conditions. This allows the mining trolley to move flexibly in complex seabed environments, adapt to changing working conditions, reduce operational risks caused by depth changes, improve the safety and reliability of the entire system, reduce unnecessary up-and-down movement, improve work efficiency, and extend the working time of each dive.

[0035] In some embodiments, there are multiple floating boxes 21, all of which are disposed on the vehicle body 1 and arranged sequentially along the width direction of the vehicle body 1. Specifically, as shown in the figure... Figure 4 As shown, there are two floating boxes 21. The two floating boxes 21 are fixed to the vehicle body 1 and are symmetrically arranged at intervals in the left and right directions. The two floating boxes 21 can ensure that the buoyancy is more evenly distributed on the vehicle body 1, which helps to maintain the horizontal attitude of the vehicle body 1 and avoid the problem of center of gravity shift caused by a single large floating box 21. In addition, 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. Furthermore, 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 does not immediately lose buoyancy and sink to the seabed, thereby improving the reliability and safety of the deep-sea mining device 100.

[0036] In some embodiments, the first crushing component 42 includes a rotating drum 421 and a plurality of crushing units 422.

[0037] The rotating cylinder 421 is mounted on the mounting bracket 41 and is rotatable relative to the mounting bracket 41 in the width direction of the vehicle body 1. The rotating cylinder 421 is detachably mounted on the mounting bracket 41 for easy replacement. Specifically, as shown... Figure 2 and Figure 5As shown, the rotating cylinder 421 is rotatably mounted on the right end of the mounting frame 41, and a motor can be installed on the rotating cylinder 421 to drive the rotating cylinder 421 to rotate on the mounting frame 41. The rotating cylinder 421 is detachably mounted on the mounting frame 41, which allows the structure of the first crushing component 42 to be replaced or adjusted according to the characteristics of the target ore to adapt to the mining needs of different types of deep-sea ore, thus ensuring the crushing efficiency of the first crushing component 42.

[0038] The crushing unit 422 is pick-shaped, and multiple crushing units 422 are arranged on the rotating cylinder 421 and spaced in multiple rows along the axial direction of the rotating cylinder 421. Each row includes several crushing units 422 spaced circumferentially along the rotating cylinder 421. Specifically, as shown... Figure 6 As shown, the crushing unit 422 is a pick-shaped cutter. In other words, the crushing unit 422 has a sharp front end and a back end. The sharp front end is suitable for efficiently crushing seabed sediments. The back end of the crushing unit 422 can be fixed to the rotating cylinder 421. Multiple crushing units 422 are arranged in multiple rows along the front-to-back direction. Each row includes several crushing units 422 arranged circumferentially along the rotating cylinder 421, so that the crushing units 422 can be evenly distributed on the rotating cylinder 421. This allows for all-round and multi-layer crushing of seabed sediments, adapting to various seabed geological conditions. In addition, when the rotating cylinder 421 starts to rotate, the sharp front end of the pick-shaped cutter 422 first penetrates the seabed sediment layer, separating the ore from the surrounding mud and sand. It can also effectively lift the ore from the sediment layer, reducing resistance and energy consumption during the excavation process. The continuously rotating rotating cylinder 421 can maintain an efficient working rhythm during the excavation process, allowing the ore to be excavated quickly. This ensures the crushing efficiency of the first crusher 42, effectively crushing both soft mud and hard rock, thus improving the equipment's applicability.

[0039] In some embodiments, the rotating drum 421 is provided with a plurality of mounting seats 423, and the plurality of mounting seats 423 are detachably connected to a plurality of crushing units 422 in a one-to-one correspondence. Specifically, as shown in the figure Figure 6 As shown, the number of mounting bases 423 is equal to the number of crushing units 422, and each mounting base 423 can be equipped with one crushing unit 422. The crushing unit 422 is detachably installed in the mounting base 423 by threaded connection or fasteners. Thus, when one of the crushing units 422 is damaged, it can be replaced or maintained, reducing maintenance costs and time, and improving maintenance efficiency.

[0040] In some embodiments, the collecting element 44 includes a collecting pipe, one end of which is fixed to the vehicle body 1 and adapted to communicate with a pump. The collecting pipe extends away from the vehicle body 1 and slopes downward. The other end of the collecting pipe is located between the vehicle body 1 and the first crushing element 42, with one end of the collecting pipe facing downward. 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 element 42. A jetting element 43 is disposed on the other end of the collecting pipe so that the jetting element 43 flushes the crushed seabed sediment into the collecting pipe. Specifically, as shown... Figure 2 and Figure 3 As shown, the outlet of the collection pipe is fixed to the vehicle body 1 and can be connected to the pump. The collection pipe extends from left to right and slopes downward, with the inlet facing downward. The collection pipe is located between the vehicle body 1 and the first crushing component 42. The inlet of the collection pipe is located to the left of the first crushing component 42 and above it. The jetting component 43 is located at the inlet of the collection pipe and adjacent to the working area of ​​the first crushing component 42. Thus, when the first crushing component 42 (rotating cylinder 421 and pick-shaped crushing unit 422) crushes the seabed sediment, the crushed material will naturally fall below the collection pipe. At this time, the jetting component 43 is activated, using high-pressure water or air to flush these crushed materials into the collection pipe, ensuring that they smoothly enter the subsequent processing system. Thus, the design of the collection pipe and the jetting component 43 are closely coordinated to form an efficient collection system, thereby seamlessly connecting the three steps of crushing, flushing and collection, ensuring the continuity and efficiency of the entire mining process.

[0041] It is worth noting that a collection chamber (not shown in the figure) can be installed on the vehicle body 1. The collection chamber is connected to the collection component 44, so that seabed sediments can be collected into the collection chamber through the collection component 44.

[0042] In some embodiments, the spraying member 43 includes a first spraying member 431 and a second spraying member 432.

[0043] The first spraying element 431 includes a first spray pipe 4311 and a first nozzle 4312. The first spray pipe 4311 can be supplied with high-pressure water and is in communication with the first nozzle 4312. The first nozzle 4312 is located on the side of the collecting pipe adjacent to the first crushing element 42, and the first nozzle 4312 extends from top to bottom and is inclined toward the side away from the first crushing element 42. Specifically, as Figure 2As shown, the first nozzle 4312 is made of high-pressure resistant and corrosion-resistant materials to ensure long-term use in deep-sea environments without damage. The inlet of the first jet pipe 4311 can be connected to a water pump. Multiple first nozzles 4312 are arranged sequentially along the front-to-back direction on the right side of the collection pipe outlet. The first nozzles 4312 extend downwards and tilt to the left. All first nozzles 4312 are connected to the first jet pipe 4311, allowing water to be ejected through the first jet pipe 4311 and then through the first nozzles 4312. The head 4312 is designed to allow the water flow to be sprayed at an angle to the left. The angle and spray force of the first nozzle 4312 are adjustable to adapt to different types of sediment layers and ore densities. By adjusting the water pressure and spray angle, the first nozzle 4312 can precisely control the impact force, effectively lifting the ore without causing excessive disturbance to the surrounding sediment layer. Thus, by adjusting the angle and position of the first nozzle 4312, loose ore can be effectively flushed off the sediment layer, ensuring that the water flow can penetrate deep into the sediment layer and generate sufficient thrust to lift the ore.

[0044] The second spraying element 432 includes a second spray pipe 4321 and a second nozzle 4322. The second spray pipe 4321 can be supplied with high-pressure water and is connected to the second nozzle 4322. The second nozzle 4322 is located on the side of the collection pipe away from the first crushing element 42, and the second nozzle 4322 extends from top to bottom and is inclined towards the side adjacent to the first crushing element 42. Specifically, as Figure 2 As shown, the inlet of the second jet pipe 4321 can be connected to a water pump. There are multiple second nozzles 4322, which are arranged sequentially along the front-to-back direction on the left side of the outlet of the collection pipe. The second nozzles 4322 extend from top to bottom and tilt to the right. All the second nozzles 4322 are connected to the second jet pipe 4321, so that the water is sprayed out through the second jet pipe 4321 and the second nozzles 4322. The arrangement of the second nozzles 4322 can make the water flow tilted to the right. The reverse water flow generated by the second nozzles 4322 can form a "water wall" to effectively prevent the ore from falling backward, so that the ore is concentrated near the rotating cylinder 421 for easy collection. The confluence of the first nozzle 4312 and the second nozzle 4322 forms an upward thrust, lifting the ore and guiding it to the inlet of the collection pipe, ensuring that the ore can be smoothly transported into the collection pipe. In addition, the high-pressure water jets sprayed by the first jetting element 431 and the second jetting element 432 are not only used to lift and guide the ore, but also to quickly clean the mud and sediment on the surface of the rotating drum 421, reducing friction between the rotating drum 421 and the ore and improving work efficiency. Through the flushing of the high-pressure water jet, the rotating drum 421 can be kept clean, avoiding jamming and wear caused by the accumulation of mud and sand.

[0045] The present invention implements a deep-sea mining device 100, which has the following advantages due to the arrangement of the first crushing component 42 and the jetting component 43:

[0046] 1. Reduced Disturbance: The first crusher 42 primarily undertakes the excavation task, while the high-pressure water jet of the jetting component 43 serves as an auxiliary tool, reducing the direct impact of the water jet on the sedimentary layer. The ore excavated by the first crusher 42 is cleaned and guided by the water jet, which allows for better control over the impact on seabed sediments.

[0047] 2. Precision Operation: Through the coordinated operation of machinery (first crushing component 42) and water jet (spraying component 43), precise excavation and clearing can be achieved, minimizing disturbance to non-target areas. The rational configuration of the front and rear jets ensures that water flow impact is only carried out in necessary areas, protecting the surrounding seabed ecosystem.

[0048] 3. Reduced Ecological Damage: Pure water jet mining systems often result in large amounts of suspended sediment, impacting the seabed ecosystem. By combining mechanical excavation and water jetting, this design can reduce the extent of sediment suspension and diffusion, thus minimizing damage to the seabed environment.

[0049] 4. Sediment control: The jet component 43 is equipped with multi-stage filtration and regulation functions, which can control the intensity and direction of water flow, avoid excessive disturbance to the sediment layer, and protect the living environment of marine life.

[0050] 5. Comprehensive Protection Measures: In addition to reducing physical disturbance, this invention also considers environmental factors such as water quality and noise. The jetting component 43 can be equipped with noise reduction and vibration damping devices to reduce noise pollution generated during the mining process. Furthermore, the water jet from the jetting component 43 is treated and filtered to ensure that no harmful substances are introduced, thus protecting the marine environment.

[0051] Therefore, by combining the first crushing component 42 and the jetting component 43, this design achieves the dual goals of efficient mining and environmental protection. The water jet system not only improves mining efficiency but also reduces damage to seabed sediments and ecosystems.

[0052] In some embodiments, the collecting device 44 further includes a conveying pipe 45, one end of which is adapted to allow high-pressure water to pass through, and the other end of which is located near the end of the collecting pipe adjacent to the first crushing member 42. The other end of the conveying pipe 45 extends in a direction away from the first crushing member 42, so that high-pressure water can be passed through the conveying pipe 45 to the collecting pipe to transport sediment. Specifically, as Figure 3 As shown, the inlet of the delivery pipe 45 can be connected to the water pump, and the outlet of the delivery pipe 45 is located at the right end of the collection pipe and inside the delivery pipe 45. The outlet of the collection pipe is set to the left, so that the high-pressure water jet from the collection pipe flows to the outlet of the collection pipe. The high-pressure water jet not only helps to push the sediment, but also ensures that the water jet can effectively push the sediment, prevent the sediment from clogging the pipe, and improve the transportation efficiency.

[0053] In some embodiments, the adjustment component 3 includes a first propeller 31, a second propeller 32, and a first detection element (not shown in the figure).

[0054] The first propeller 31 and the second propeller 32 are rotatably mounted on the vehicle body 1 and are spaced apart from each other along the width direction of the vehicle body 1. The first propeller 31 and the second propeller 32 are used to adjust the attitude and position of the vehicle body 1. Specifically, as shown in the figure... Figure 3 As shown, both the first propeller 31 and the second propeller 32 are fixed to the vehicle body 1 by a sturdy bracket or shaft connector, and the first propeller 31 and the second propeller 32 are spaced apart from each other in the front-rear direction to ensure that they remain stably connected under high pressure. The first propeller 31 and the second propeller 32 can be driven by a motor, so by adjusting the speed and direction of rotation of the first propeller 31 and the second propeller 32, the vehicle body 1 can be finely adjusted in the horizontal and vertical directions to ensure that the vehicle can accurately reach the predetermined position and remain stable, or adjust the attitude of the vehicle body 1. (e.g., pitch angle, roll angle, and yaw angle) to ensure the vehicle maintains stability and correct direction of travel in complex seabed environments. 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 adjustments. For example, when the roll angle needs to be adjusted, one propeller (e.g., the first propeller 31) may increase thrust, while the other propeller (e.g., the second propeller 32) may decrease 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 steering torque.

[0055] In some embodiments, when the first detection element detects that the attitude and position of the vehicle body 1 deviate from a preset value, at least one of the first propeller 31 and the second propeller 32 operates. Specifically, the first detection element can be a sensor, including but not limited to attitude angle sensors, position sensors, and acceleration sensors. The first detection element continuously monitors the attitude and position data of the vehicle body 1 and sends it to the control system. If a deviation is detected, the control system calculates the required adjustment amount according to an algorithm and instructs the corresponding first propeller 31 and second propeller 32 to start or change their rotation speed to correct the deviation. By activating at least one of the first propeller 31 and the second propeller 32, the attitude and position of the vehicle body 1 are adjusted. For example, when the vehicle body 1 tilts forward, the thrust of the front first propeller 31 is increased or the thrust of the rear second propeller 32 is decreased to restore the vehicle body 1 to balance.

[0056] In some embodiments, the deep-sea mining apparatus 100 further includes a second crushing component 5, which includes a housing 51 and a crushing roller 52. The housing 51 is mounted on the vehicle body 1 and communicates with the collection member 44 so that the sediment collected by the collection member 44 is transported to the crushing roller 52. The crushing roller 52 is rotatably disposed within the housing 51 to crush the sediment. Specifically, as Figure 1 and Figure 3 As shown, the housing 51 is positioned above the vehicle body 1, and a crushing chamber can be formed within the housing 51. The crushing roller 52 is rotatably mounted within the housing 51 and driven by a motor. The crushing roller 52 has protrusions and toothed structures to enhance the crushing effect, allowing it to apply shearing and impact forces to the sediment during rotation, breaking it into smaller particles. The housing 51 can be connected to the outlet of the collection pipe and the inlet of the collection bin, enabling the crushing roller 52 to crush the sediment. Thus, the collected seabed sediment is initially crushed and refined by the second crushing component 5, breaking larger sediment pieces into smaller, more uniform particles, facilitating subsequent processing and transportation. Furthermore, the crushed sediment is easier to further process (such as screening and separation), improving the efficiency of the entire mining process. Smaller particles are also easier to transport and store, reducing the risk of equipment blockage.

[0057] In some embodiments, the crushing roller 52 is detachably disposed within the housing 51 for replacement. Thus, the crushing roller 52 can be replaced or adjusted according to the characteristics of the target ore to meet the mining requirements of different types of deep-sea ores, ensuring the crushing efficiency of the crushing roller 52.

[0058] In some embodiments, the vehicle body 1 includes a body 11, a first wheel 12, a second wheel 13, a buffer 14, and a drive belt 15.

[0059] The floating component 2, adjustment component 3, and acquisition component 4 are all mounted on the vehicle body 11. Specifically, as follows... Figure 1 As shown, the vehicle body 11 is made of high-strength, corrosion-resistant materials and has good pressure resistance, enabling it to be used for a long time in the 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 a mounting base for the floating component 2, the adjustment component 3, and the collection component 4.

[0060] The first set of 12 wheels is rotatably mounted on the vehicle body 11 and spaced apart along the direction of the vehicle body 11. Specifically, as shown... Figure 2 As shown, the first wheel 12 is a driving wheel and there are multiple first wheels 12. One part of the multiple first wheels 12 is located on the front side of the vehicle body 11 and is spaced apart in the left and right direction. Another part of the multiple first wheels 12 is located on the rear side of the vehicle body 11 and is spaced apart in the left and right direction.

[0061] The second wheel 13 is rotatably disposed below the first wheel 12 and spaced vertically from the first wheel 12. The second wheel 13 is movable vertically relative to the first wheel 12. Specifically, as shown... Figure 2 and Figure 3 As shown, there are multiple second wheels 13. A portion of the multiple second wheels 13 is located on the front side of the vehicle body 11 and is spaced apart in the left and right direction and located below the first wheel 12. The first wheel 12 and the second wheel 13 are spaced apart in the up and down direction. Another portion of the multiple first wheels 12 is located on the rear side of the vehicle body 11 and is spaced apart in the left and right direction. The first wheel 12 and the second wheel 13 are spaced apart in the up and down direction.

[0062] The buffer 14 is disposed between the vehicle body 1 and the second wheel 13 and connected to the vehicle body 1 and the second wheel 13, so that the buffer 14 has a buffering force to drive the second wheel 13 downward. Specifically, as shown in the figure... Figure 2 As shown, the buffer 14 is a spring, 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. Thus, when the second wheel 13 encounters a protrusion 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 its components, as well as the stability of the vehicle body 1 when it travels.

[0063] A transmission belt 15 is fitted onto 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 circumferential surface of the transmission belt 15 has a plurality of protrusions 151, which are spaced apart circumferentially along the transmission belt 15. The cross-sectional area of ​​the protrusions 151 gradually decreases away from the outer circumferential surface of the transmission belt 15. Specifically, as shown... Figure 2 As shown, the transmission belt 15 is annular and 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. The outer circumferential surface of the transmission belt 15 has multiple protrusions 151 spaced along the circumference of the transmission belt 15, and their cross-sectional area gradually decreases away from the outer circumferential surface of the transmission belt 15. The protrusions 151 increase the friction between the transmission belt 15 and the seabed surface, ensuring that the vehicle can maintain good traction on wet or soft seabed surfaces. The shape design of the protrusions 151 also helps to expel sediment 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 vehicle's grip and stability, adapting to the complex and ever-changing seabed environment.

[0064] The deep-sea mining device 100 also includes a control component (not shown in the figure). The control component is connected to the floating component 2, the adjustment component 3, and the collection component 4, respectively. This allows the control component to control the adjustment component 3 to adjust the attitude and position of the vehicle body 1 based on changes in buoyancy of the floating component 2 and the collection status of the collection component 4. Alternatively, the control component can control the jet intensity and angle of the jetting component 43 to reduce sediment suspension and control the diffusion range. Specifically, the control component is a controller. It is tightly connected to the floating component 2, the adjustment component 3, and the collection component 4 via connecting lines, forming a closed-loop control system. This allows the control component to 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 based on this information. For example, the control component comprehensively judges the current working status of the deep-sea mining device 100 based on the buoyancy change data provided by the floating component 2 and the collection status reported by the collection component 4. When a deviation or a situation requiring adjustment is detected, the control component immediately activates the adjustment component 3 to optimize the attitude and position of the vehicle body 1 through precise adjustments, ensuring that the vehicle can stably and efficiently perform mining tasks.

[0065] The control components also possess the ability to precisely control the jetting element 43, flexibly adjusting the jet intensity and angle of the jetting element 43 according to actual needs. Thus, through precise jetting control, the deep-sea mining device 100 can achieve efficient and environmentally friendly mining operations without damaging the seabed ecosystem.

[0066] The deep-sea mining apparatus 100 also includes a second detection component (not shown in the figure). This second detection component is located on the outer periphery of the vehicle body to monitor the water flow velocity, terrain changes, and ore density around the vehicle body, thereby adjusting the floating assembly 2, the adjustment assembly 3, and the acquisition assembly 4. Specifically, the second detection component includes a flow velocity sensor, a terrain sensor, and a ore density sensor, all of which are located on the outer periphery of the vehicle body, enabling real-time monitoring of key data such as water flow velocity, terrain changes, and ore density. Thus, 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, allowing for timely adjustment of the buoyancy output of the floating assembly 2. This ensures that the vehicle body 1 maintains a stable attitude and position in complex water flow environments, helping to reduce operational interruptions caused by water flow impacts and improving the continuity and stability of mining operations.

[0067] In addition, the second detection component can accurately identify the undulations and changes in the seabed topography, providing precise terrain data for the adjustment component 3. This allows the vehicle body 1 to flexibly adjust its travel route and working posture to adapt to mining needs under different terrain conditions, thereby reducing operational difficulty and improving mining efficiency and safety.

[0068] Finally, the second detection component provides precise collection guidance for the collection module 4 by monitoring ore density in real time. When a high-density ore area is detected, the vehicle body 1 can automatically adjust the working status of the collection module 4 to improve collection efficiency and ore recovery rate. At the same time, by monitoring changes in ore density, the vehicle body 1 can also promptly discover potential mineral resources, providing strong support for subsequent mining operations.

[0069] The following is based on Figures 1-6 This invention provides a detailed description of the deep-sea mining apparatus 100 according to an embodiment of the present invention.

[0070] like Figures 1 to 6 As shown in the figure, this specification provides a new type of deep-sea environmentally friendly multi-functional 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 assembly, a collection assembly 4 and a floating assembly 2.

[0071] The body 11 is made of high-strength aluminum alloy, which can provide sufficient strength and stability in the high-pressure environment of the deep sea. The aluminum alloy has excellent corrosion resistance, which can resist seawater corrosion and improve 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 overall strength, reduce deformation, and improve the operational stability of the equipment.

[0072] The chassis 11 serves as the supporting structure for the entire mining trolley, housing the hydraulic motor track system and other functional modules. The chassis 11 features a high-strength structural design, making it suitable for stable operation in deep-sea, high-pressure environments.

[0073] The body 11 supports all structural components of the mining trolley, ensuring mechanical connections between functional modules. The hydraulic motor and track system are fixed to the body 11, providing power and stable support for the trolley's movement. The protrusions 151 of the drive belt 15 are designed to distribute ground pressure, preventing it from sinking into soft mud, and are equipped with an automatic adjustment function to adapt to different seabed topographic variations.

[0074] The tracked system includes a first wheel 12, a second wheel 13, a buffer 14, and a drive belt 15. The first wheel 12 is driven by a hydraulic motor, enabling the trolley to efficiently overcome obstacles and move flexibly. The drive belt 15 is designed to effectively distribute the ground pressure, reducing the risk of the equipment getting stuck in soft mud, and also has an automatic adjustment function to adapt to different seabed terrains.

[0075] The drive belt 15 is made of a composite material of highly wear-resistant rubber and steel, which is corrosion-resistant and has good flexibility. The design of the steel first wheel 12 and second wheel 13, as well as the buffer 14, enables the track system to adapt to complex seabed terrain. The buffer 14 absorbs the vibrations caused by terrain undulations to the mining trolley during the trolley's movement, reducing stress on the tracks and making the track system more stable and reliable.

[0076] Adjustment components ( Figure 3 The first propeller 31 and the second propeller 32 enable the vehicle to achieve precise positioning and attitude adjustment in complex seabed environments. The first propeller 31 and the second propeller 32 are integrated with the vehicle body 1, and the thrust and direction of the propellers are adjusted in real time through an electro-hydraulic control system to ensure the stability of the vehicle under strong ocean current interference.

[0077] The first propeller 31 and the second propeller 32 are mainly made of high-strength alloy steel, possessing excellent corrosion resistance and durability. The compact design of the first propeller 31 and the second propeller 32 enables precise positioning under strong ocean currents. The use of an electro-hydraulic control system allows for real-time adjustment of the thrust and direction of the first propeller 31 and the second propeller 32, ensuring the stability of the trolley during operation in complex seabed environments.

[0078] Furthermore, the positioning and attitude of the trolley are precisely controlled by the first propeller 31 and the second propeller 32, enabling it to operate stably in high-velocity and highly turbulent seabed environments. The electro-hydraulic control system allows for real-time adjustment of the thrust and direction of the first propeller 31 and the second propeller 32, ensuring that the trolley can still accurately control its operating position and reduce drift even under conditions of significant ocean currents and water flow disturbances.

[0079] The first crushing component 42 and the jetting component 43 are the main operating modules of the mining trolley, including a rotating drum 421, a crushing unit 422, a first nozzle 4312, a first jetting pipe 4311, a second jetting pipe 4321, a second nozzle 4322, and a high-pressure water pump. The first crushing component 42 can efficiently crush seabed sediments, and the jetting component 43 sprays high-pressure water into the crushing area to assist in loosening and transporting the sediments. The jetting system is designed for low disturbance and high efficiency, effectively reducing the diffusion of suspended particles in the sediment layer.

[0080] The rotating cylinder 421 is made of high-strength steel and corrosion-resistant alloy materials, and its surface is specially treated to enhance wear resistance. The first nozzle 4312, the first spray pipe 4311, the second spray pipe 4321, and the second nozzle 4322 are all made of corrosion-resistant stainless steel, capable of resisting seawater corrosion. The high-pressure water pump is made of special rubber material, possessing high strength and high pressure resistance.

[0081] The first crushing component 42 effectively breaks and loosens hardened sediments in complex terrain by rotating and scraping them. The conveying pipe 45 then transports the crushed material to the trolley's lifting pump system. The jetting component 43 assists in loosening sediments under low-disturbance conditions, preventing further damage to the seabed ecosystem.

[0082] The floating box 21 provides additional buoyancy support, reducing the pressure of the drive belt 15 on the soft mud surface. The buoyancy box 42 provides additional buoyancy support, reducing the pressure of the trolley on the seabed topography, helping to avoid sinking into the soft mud, while maintaining the trolley's operational stability. It can be connected to the ore collection component 4 via a ore pump and ore conveying riser, using a high-efficiency pumping system to transport the ore and sediment mixture to the sea surface. The ore pump and ore conveying riser are made of high-strength stainless steel, possessing excellent corrosion resistance and pressure resistance. The buoyancy box is made of a lightweight, high-strength alloy, providing additional buoyancy support and reducing the pressure of the tracked system on the soft mud surface.

[0083] In addition, the mining trolley is equipped with multifunctional auxiliary devices, including a searchlight 6 for deep-sea operation lighting, an electrical control cabinet for centralized control of various systems, and a second crusher 5 for further crushing of large sediment blocks. The coordinated operation of these functional modules ensures the mining trolley's high operational efficiency and environmental friendliness.

[0084] The searchlight 6 uses a high-intensity LED light source, featuring low power consumption and high brightness, providing stable lighting for deep-sea operations. The electrical control cabinet is made of corrosion-resistant materials and integrates control units for various systems, ensuring coordinated operation of the mining trolley. The second crushing component 5 is made of high-strength steel, possessing excellent wear resistance and compressive strength, capable of further crushing larger sediments.

[0085] The coordinated operation of these auxiliary devices enables the mining trolley to operate efficiently in the complex deep-sea environment while minimizing environmental damage. The searchlight 6 ensures visibility in the dark seabed, while the electrical control cabinet provides coordinated control between systems, ensuring the smooth operation of each functional module. The second crusher 5 further processes large pieces of sediment, reducing the sediment's environmental impact.

This combination significantly improves mining efficiency, especially in seabed environments with alternating soft and hard surfaces, enabling efficient handling of changes in ore properties and achieving continuous and efficient mining operations.

[0088] High stability: This invention, through the coordinated design of the track system and the floating component 2, uses a near-involute high-tooth rubber material for the transmission belt 15, combined with a double floating suspension and a lateral swing beam structure, effectively improving the vehicle's grip and obstacle-crossing capabilities. The floating component 2 can adjust the buoyancy in real time according to seabed conditions, ensuring the vehicle's operational stability in different deep-sea environments, especially in steep slopes, soft mud, and irregular terrain, exhibiting significant anti-slip and anti-overturning capabilities.

[0089] Environmental Protection: This invention prioritizes minimizing disturbance to the seabed ecosystem during its design. By optimizing the water jet flow rate and velocity, it reduces disturbance to the sediment layer and minimizes the impact of suspended sediments on the surrounding environment. Simultaneously, the overall structural design of the equipment avoids excessive damage to the original seabed morphology, reducing disruption to the seabed ecosystem and thus achieving a more environmentally friendly mining method.

[0090] Easy to operate: This utility model's trolley system integrates multiple functional modules, including a data transmission and remote control system, and an electro-hydraulic proportional control system. Operators can precisely control the trolley through the real-time communication module. Simultaneously, the addition of automatic adjustment functions significantly reduces the need for manual intervention, making equipment operation simpler and more efficient. Even in complex deep-sea conditions, high-precision operation can be easily achieved.

[0091] Operational reliability: This invention incorporates multiple redundancy protection mechanisms, such as automatic thrust direction adjustment in the dynamic positioning propeller system, overload protection mechanism in electro-hydraulic proportional control, and dual-system switching function between the track system and the mining pump. These designs significantly enhance the system's reliability in extreme deep-sea environments, ensuring stable and efficient operation under high pressure, low temperature, and long-term operating conditions.
