[0032] Referring to Figure 1 , a schematic diagram of a new type of green mining system for deep-sea sulfide resources provided by an embodiment of this application is shown; referring to Figure 2 , a schematic diagram of a submarine mining subsystem provided by an embodiment of this application is shown; referring to Figure 3, showing a schematic diagram of the transportation of an ore by a pipeline transportation subsystem and a sea surface support subsystem. As Figures 1 to 3 shown, the new type of green mining system for deep-sea sulfide resources includes: a sea surface support subsystem 10, a pipeline transportation subsystem 20, a comprehensive maintenance and environmental perception subsystem 30, and a seabed mining subsystem 40.

[0033] The sea surface support subsystem 10 is used to be set on the sea surface, and the seabed mining subsystem 40 is used to be set on the seabed for closed mining at the seabed. The pipeline transportation subsystem 20 is connected to the seabed mining subsystem 40, and the pipeline transportation subsystem 20 is used to transport the minerals mined by the seabed mining subsystem 40 to the sea surface support subsystem 10. The comprehensive maintenance and environmental perception subsystem 30 is set near the pipeline transportation subsystem 20, the seabed mining subsystem 40, and on the sea surface support subsystem to monitor various data during the mining process; among them, the sea surface support subsystem 10 is a semi-submersible platform.

[0034] The sea surface support subsystem 10 is set on the sea surface, and the seabed mining subsystem 40 is set on the seabed for vertical closed green mining at the seabed. The pipeline transportation subsystem 20 is connected to the seabed mining subsystem 40, and the pipeline transportation subsystem 20 is used to transmit the minerals mined by the seabed mining subsystem 40 to the sea surface support subsystem 10. The comprehensive maintenance and environmental perception subsystem 30 is respectively set in the sea surface support platform 11 and seawater. The comprehensive maintenance and environmental perception subsystem is used for hardware maintenance, environmental monitoring, integrated control, etc. of the mining system; among them, the sea surface support platform 11 is a semi-submersible platform.

[0035] It should be noted that the sea surface support subsystem 10 includes the sea surface support platform 11.

[0036] In the embodiment of the present application, since the pipeline transportation subsystem 20 is connected to the seabed mining subsystem 40 and the sea surface support subsystem 10 is arranged on the sea surface, when it is necessary to mine the seabed, the seabed mining subsystem 40 is deployed on the seabed, and the seabed mining subsystem 40 conducts vertical closed mining. The minerals mined by the seabed mining subsystem 40 can be transported to the sea surface support subsystem 10 through the pipeline transportation subsystem 20. The sea surface support platform 11 is a semi-submersible platform, which can prevent the pipeline transportation subsystem 20 from transporting the minerals mined by the seabed mining subsystem 40 to a ship, resulting in limited continuity and stability of the mining system. That is, in the embodiment of the present application, by setting the sea surface support platform 11 as a semi-submersible platform and the seabed mining subsystem 40 conducting vertical closed mining on the seabed, during the process of mining minerals by the seabed mining subsystem 40, the environmental pollution to the seabed is relatively small. After the minerals mined by the seabed mining subsystem are transported to the sea surface support subsystem 10 through the pipeline transportation subsystem 20, the minerals are stored on the sea surface support platform 11, which can effectively avoid the problems of limited storage capacity of the ship and limited continuity of the mining operation. That is, in the embodiment of the present application, during seabed mining, not only is the environmental pollution to the seabed relatively small, but also the continuity and stability of seabed mining can be achieved.

[0037] In the related art, when mining the seabed, usually a ship floats on the sea surface, and a mining machine is placed on the seabed. The mining machine conducts mining on the seabed, and the mining machine is connected to the pipeline transportation subsystem 20. The pipeline transportation subsystem 20 transports the minerals mined by the mining machine to the ship. In this way, during the process of mining minerals by the mining machine, a large amount of dust will be generated on the bottom surface of the seabed by the mining machine, resulting in serious turbidity of the sea water on the seabed and affecting the seabed environment. The ship is occupied by the mined minerals, resulting in the ship being able to only dock at the corresponding sea surface and unable to perform other tasks, greatly reducing the utilization rate of the ship. Moreover, the ship is greatly affected by the marine weather, making it extremely difficult to achieve the stability and continuity of seabed mining. In the embodiment of the present application, by setting the sea surface support platform 11 as a semi-submersible platform and the pipeline transportation subsystem 20 transporting the mined minerals to the semi-submersible platform, the ship can be liberated, enabling the ship to move freely and perform other tasks, improving the utilization rate of the ship. In addition, the semi-submersible platform is relatively stable and not easily affected by sea waves or sea winds, making the minerals placed on the semi-submersible platform relatively stable. In addition, the seabed mining subsystem 40 conducts closed mining, so when the seabed mining subsystem 40 mines minerals on the seabed, less dust generated during the mining process is transmitted to the seabed, only in the mine pit 001 mined by the seabed mining subsystem 40, thus avoiding pollution of the seabed environment and effectively protecting the seabed environment.

[0038] It should be noted that in the embodiments of the present application, once the pipeline transportation subsystem 20 transports the mined minerals to the sea surface support platform 11, when the minerals need to be transported, the sea surface transfer ship 16 can be used to transport the minerals on the sea surface support platform 11. That is, the sea surface transfer ship 16 is moved around the sea surface support platform 11, and the minerals on the sea surface support platform 11 are carried onto the sea surface transfer ship 16, and the sea surface transfer ship 16 transports the minerals to the destination.

[0039] In addition, in some embodiments, the seabed mining subsystem 40 includes a support module 41, an isolation cover 42, a mining module 43, and a temporary storage bin 44. The isolation cover 42 is connected to the support module 41, and the temporary storage bin 44 is connected to the pipeline transportation subsystem 20. The mining module 43 is used to excavate a mine shaft 001 on the seabed and mine ores in the mine shaft 001. The isolation cover 42 is used to prevent the turbid water body generated during the mining process from overflowing, so that the seabed mining subsystem 40 can perform vertical closed green mining. The temporary storage bin 44 is used to temporarily store the ores mined by the mining module 43 and perform preliminary filtration, and then transport them to the sea surface support subsystem through the pipeline transportation subsystem 20.

[0040] Since the isolation cover 42 and the mining module 43 are provided, when the mining module 43 excavates the mine shaft 001 on the seabed, the isolation cover 42 can cover the mine shaft 001, so that the dust generated during the excavation process by the mining module 43 is blocked by the isolation cover 42, causing the suspended matter to concentrate in the mine shaft 001 with more suspended matter, and less suspended matter leaks to the seabed. Even all the suspended matter is concentrated in the mine shaft 001, thus realizing closed mining. That is, by setting the isolation cover 42 and the mining module 43, the seabed environment can be effectively protected during the process of mining the seabed.

[0041] It should be noted that in the embodiments of the present application, the mining module 43 can excavate the mine shaft 001 in a direction perpendicular to the seabed, so that the extension direction of the excavated mine shaft 001 is perpendicular to the seabed, that is, the extension direction of the mine shaft 001 is the vertical direction, and the mining module 43 can expand and contract in the horizontal direction to enlarge the size of the mine shaft 001. During the process of excavating the mine shaft 001, the isolation cover 42 will cover the opening of the mine shaft 001, so that the dust generated during the mining process by the mining module 43 is only concentrated in the mine pit 001, preventing the dust from leaking to the seabed.

[0042] In addition, in the embodiments of the present application, openings can be provided on the isolation cover 42, and the mining module 43 passes through these openings, and the mining module 43 can move relative to the isolation cover 42. Thus, during the process of the mining module 43 mining minerals, the mining module 43 moves relative to the isolation cover 42, and the isolation cover 42 always covers the opening of the mine shaft 001 excavated by the mining module 43, preventing the dust from leaking to the seabed.

[0043] In addition, in some embodiments, the new green mining system for deep-sea sulfide resources in mineral mining may further include an energy supply module 12, which is disposed on the sea surface support platform 11, or the energy supply module is disposed on the sea surface around the sea surface support subsystem 10; wherein, the energy supply module 12 is electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20 respectively, and is used to supply electrical energy to the seabed mining subsystem 40 and the pipeline transportation subsystem 20.

[0044] Since the energy supply module 12 is electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20 respectively, therefore, the electrical energy generated by the energy supply module 12 can be transmitted to the seabed mining subsystem 40 and the pipeline transportation subsystem 20, enabling the seabed mining subsystem 40 and the pipeline transportation subsystem 20 to operate normally. And the energy supply module 12 can be disposed on the sea surface support platform 11 or on the sea surface around the sea surface support subsystem 10, so that the distance between the energy supply module 12 and the pipeline transportation subsystem 20 and the distance between the energy supply module 12 and the seabed mining subsystem 40 can be relatively close, which can save the length of the cable required to electrically connect the energy supply module 12 to the pipeline transportation subsystem 20, and can also save the length of the cable required to electrically connect the energy supply module 12 to the seabed mining subsystem 40.

[0045] In addition, in some embodiments, the energy supply module 12 may include a plurality of photovoltaic modules and brackets. The brackets are disposed on the sea surface support platform 11, and the plurality of photovoltaic modules are disposed on the brackets. The photovoltaic modules are electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20 respectively, and are used to supply electrical energy to the seabed mining subsystem 40 and the pipeline transportation subsystem 20; or, the energy supply module 12 includes a wind power generation component and a power generation support frame. The power generation support frame is disposed on the sea surface support platform 11, and the wind power generation component is disposed on the power generation support frame. The wind power generation component is electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20 respectively, and is used to supply electrical energy to the seabed mining subsystem 40 and the pipeline transportation subsystem 20; or, the energy supply module 12 includes multiple groups of wave energy generation components, which are disposed on the sea surface around the sea surface support subsystem 10. The wave energy generation components are electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20 respectively, and are used to supply electrical energy to the seabed mining subsystem 40 and the pipeline transportation subsystem 20; or, the energy supply module 12 includes multiple groups of tidal energy generation components, which are disposed on the sea surface around the sea surface support subsystem 10. The tidal energy generation components are electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20 respectively, and are used to supply electrical energy to the seabed mining subsystem 40 and the pipeline transportation subsystem 20.

[0046] When the energy supply module 12 includes multiple photovoltaic components and brackets, the brackets can be arranged on the sea surface support platform 11, and the multiple photovoltaic components can be arranged on the brackets. Thus, the photovoltaic components can convert the sunlight irradiating on the sea surface, that is, convert solar energy into electric energy, and then transmit the electric energy to the pipeline conveying subsystem 20 and the seabed mining subsystem 40, enabling the normal operation of the pipeline conveying subsystem 20 and the seabed mining subsystem 40. That is, by arranging multiple photovoltaic components, solar energy can be effectively utilized, maximizing the utilization of clean energy, ensuring the normal operation of the pipeline conveying subsystem 20 and the seabed mining subsystem 40, and avoiding the use of thermal power generation to supply power to the pipeline conveying subsystem 20 and the seabed mining subsystem 40 in related technologies. Furthermore, environmental protection can be improved. Among them, the brackets can also be arranged on the sea surface around the sea surface support subsystem 10.

[0047] When the energy supply module 12 includes wind power generation components and a power generation support frame, the power generation support frame can be arranged on the sea surface support platform 11, and the wind power generation components can be arranged on the power generation support frame. Thus, the wind power generation components can convert the wind energy on the sea surface into electric energy, and then transmit the electric energy to the pipeline conveying subsystem 20 and the seabed mining subsystem 40, enabling the normal operation of the pipeline conveying subsystem 20 and the seabed mining subsystem 40. That is, by arranging wind power generation components, the wind energy on the sea surface can be effectively utilized, maximizing the utilization of clean energy, ensuring the normal operation of the pipeline conveying subsystem 20 and the seabed mining subsystem 40, and avoiding the use of thermal power generation to supply power to the pipeline conveying subsystem 20 and the seabed mining subsystem 40 in related technologies. Furthermore, environmental protection can be improved. Among them, the power generation support frame can also be arranged on the sea surface around the sea surface support subsystem 10.

[0048] When the energy supply module 12 includes multiple groups of wave energy generation components, the multiple groups of wave energy generation components can be arranged on the sea surface around the sea surface support subsystem 10. Thus, the wave energy generation components can convert the wave energy irradiating on the sea surface, that is, convert wave energy into electric energy, and then transmit the electric energy to the pipeline conveying subsystem 20 and the seabed mining subsystem 40, enabling the normal operation of the pipeline conveying subsystem 20 and the seabed mining subsystem 40. That is, by arranging multiple groups of wave energy generation components, wave energy can be effectively utilized, maximizing the utilization of clean energy, ensuring the normal operation of the pipeline conveying subsystem 20 and the seabed mining subsystem 40, and avoiding the use of thermal power generation to supply power to the pipeline conveying subsystem 20 and the seabed mining subsystem 40 in related technologies.

[0049] When the energy supply system 40 includes multiple groups of tidal energy power generation components, the multiple groups of tidal energy power generation components can be arranged on the sea surface around the sea surface support subsystem 10. Thus, the tidal energy power generation components can convert the tidal energy irradiated on the sea surface, that is, convert the tidal energy into electrical energy, and then transmit the electrical energy to the pipeline transportation subsystem 20 and the seabed mining subsystem 40, enabling the normal operation of the pipeline transportation subsystem 20 and the seabed mining subsystem 40. That is, by arranging multiple groups of tidal energy power generation components, tidal energy can be effectively utilized, maximizing the utilization of clean energy, ensuring the normal operation of the pipeline transportation subsystem 20 and the seabed mining subsystem 40, and avoiding the use of thermal power generation to supply power to the pipeline transportation subsystem 20 and the seabed mining subsystem 40 in related technologies, thereby improving environmental protection.

[0050] In addition, in the embodiment of the present application, the new type of green exploitation system for deep-sea sulfide resources may further include an energy storage module. The energy storage module is arranged in the sea surface support subsystem 10 and is electrically connected to the energy supply module 12. The energy storage module is used to store the electrical energy generated by the energy supply module 12. Among them, by arranging the energy storage module, the energy storage module can store the excess electrical energy generated by the energy supply module 12, and the energy storage module can be electrically connected to the pipeline transportation subsystem 20 and the seabed mining subsystem 40 respectively through a switch component. Thus, when the energy supply module 12 fails, the switch component can be in a closed state, and the energy storage module can transmit the stored electrical energy to the pipeline transportation subsystem 20 and the seabed mining subsystem 40, enabling the normal operation of the pipeline transportation subsystem 20 and the seabed mining subsystem 40. After the energy supply module 12 is repaired, the switch component is then in an open state, and the energy supply module 12 supplies electrical energy to the pipeline transportation subsystem 20 and the seabed mining subsystem 40.

[0051] It should be noted that the energy storage module can be an energy storage battery pack.

[0052] In addition, in some embodiments, the new type of green exploitation system for deep-sea sulfide resources may further include an ore bin 14. The ore bin 14 is arranged on the sea surface support platform 11. The ore bin 14 is connected to the ore preliminary selection module 13. The pipeline transportation subsystem 20 is used to transport the minerals mined by the seabed mining subsystem 40 to the ore bin 14.

[0053] Since the ore bin 14 is connected to the pipeline transportation subsystem 20, once the seabed mining subsystem 40 extracts minerals, after the minerals move into the pipeline transportation subsystem 20, the pipeline transportation subsystem 20 can transport the minerals to the primary ore selection module 13. After the primary ore selection module 13 performs primary ore selection, it transports the ore to the ore bin 14. Thus, the ore bin 14 can store the minerals, facilitating the transfer of the minerals by a ship later. This can avoid the problem that the minerals are scattered on the sea surface support platform 11 and are not easy to transfer.

[0054] It should be noted that in the embodiment of the present application, the pipeline transportation subsystem 20 may include a lift pump 21, a relay station 22, a rigid pipe 23, and a flexible pipe 24. The lift pump 21 is connected to the riser pipe 23, the relay station 22 is connected to the lift pump 21 through the riser pipe 23, and the flexible pipe 24 is connected to the relay station 22. In practical applications, the flexible pipe 24 can be connected to the seabed mining subsystem 40 at one end and to the relay station 22 at the other end, and multiple lift pumps 21 are provided. After being lifted by the multiple lift pumps 21, the minerals mined by the seabed mining subsystem 40 are transported to the flexible pipe and then stored in the relay station 22 for transfer. Once the minerals enter the rigid pipe 23, the minerals can be lifted to the sea surface support platform 11 through the rigid pipe 23. Among them, the number of rigid pipes 23 can be multiple, and the multiple rigid pipes 23 are connected end to end. The energy supply system 40 is electrically connected to the lift pump 21 to supply electrical energy to the lift pump 21.

[0055] In addition, in some embodiments, the new type of green mining system for deep-sea sulfide resources may further include a primary ore selection module 13. The primary ore selection module 13 is arranged in the sea surface support subsystem 10 and is connected to the ore bin 14. The primary ore selection module 13 is used to perform primary selection on the sulfide ore transported by the pipeline transportation subsystem 20 and then transport it to the ore bin 14. By setting the primary ore selection module 13, the pipeline transportation subsystem 20 transports the minerals mined by the seabed mining subsystem 40 to the primary ore selection module 13. The primary ore selection module 13 can perform preliminary screening on the ore to remove impurities in the ore, so that the ore stored in the subsequent ore bin 14 has fewer impurities.

[0056] In addition, in some embodiments, the new type of green mining system for deep-sea sulfide resources may further include an anti-oxidation module 15; the anti-oxidation module 15 is connected to the ore bin 14, the anti-oxidation module 15 stores a protective gas, and the anti-oxidation module 15 is used to inject the protective gas into the ore bin 14 so that the minerals in the ore bin 14 come into contact with the protective gas, and the protective gas is used to prevent the minerals from oxidizing.

[0057] Since the anti-oxidation module 15 is connected to the ore bin 14 and stores a protective gas, the protective gas can be injected into the ore bin 14 through the anti-oxidation module 15. Once the minerals are transported to the ore bin 14 by the primary ore separation module 13, the minerals will come into contact with the protective gas, thus avoiding the problem that the minerals are oxidized by the oxygen in the air in the ore bin 14, which affects the subsequent utilization of the minerals. That is, by setting the anti-oxidation module 15, the anti-oxidation module 15 can inject the protective gas into the ore bin 14, so that the minerals in the ore bin 14 are less oxidized, avoiding the reduction of the subsequent utilization rate of the minerals due to oxidation. That is, setting the anti-oxidation module 15 can effectively improve the utilization rate of the minerals.

[0058] It should be noted that the protective gas can be nitrogen. Of course, the protective gas can also be other types of gases. For example, the protective gas is argon. The specific type of the protective gas is not limited in the embodiments of the present application.

[0059] In addition, in the embodiments of the present application, the anti-oxidation module 15 may include a transmission pipe and a gas storage member. The gas storage member is connected to the transmission pipe, and the transmission pipe is connected to the ore bin 14. The transmission pipe can transport the protective gas in the gas storage member to the ore bin 14 to protect the minerals in the ore bin 14.

[0060] In addition, in some embodiments, the new green mining system for deep-sea sulfide resources may further include an integrated maintenance and environmental perception subsystem 30. The integrated maintenance and environmental perception subsystem 30 is used to move along the extension direction of the pipeline transportation subsystem 20 and the subsea mining subsystem 40 on the seabed to perform hardware maintenance on the pipeline transportation subsystem 20 and the subsea mining subsystem 40 and monitor the hardware and the environment during the mining process. Through such a setting, during the mining process of the subsea mining subsystem 40, the integrated maintenance and environmental perception subsystem 30 can monitor the pipeline transportation subsystem 20 and the subsea mining subsystem 40 in real time, monitor whether the pipeline transportation subsystem 20 leaks and discharges minerals into the sea, causing pollution to the sea water. And the integrated maintenance and environmental perception subsystem 30 can also monitor whether the pipeline transportation subsystem 20 is damaged to ensure that the pipeline transportation subsystem 20 can transport minerals relatively safely. Moreover, the integrated maintenance and environmental perception subsystem 30 can monitor the impact of the subsea mining subsystem 40 on the surrounding environment during the mining process to avoid damaging the environment. At the same time, the integrated maintenance and environmental perception subsystem 30 can perform real-time maintenance on the hardware of the pipeline transportation subsystem 20 and the subsea mining subsystem 40 to ensure the continuity and stability of the mining process.

[0061] In addition, in some embodiments, the integrated maintenance and environmental perception subsystem 30 may include a hardware maintenance device 31, a hardware and environmental monitoring device 32, a platform monitoring device 33, and monitoring sensors; the monitoring sensors are disposed on the hardware maintenance device 31 and the hardware and environmental monitoring device 32. The hardware maintenance device is movable along the extension direction of the pipeline transportation subsystem 20 and the seabed mining subsystem 40 to perform hardware maintenance on the pipeline transportation subsystem 20 and the seabed mining subsystem 40. The hardware and environmental detection device 32 is disposed on the pipeline transportation subsystem 20 and the seabed mining subsystem 40 to perform hardware-side detection and mining environment monitoring. The monitoring sensors are disposed on the pipeline transportation subsystem 20 and the seabed mining subsystem 40 to monitor the working states and parameters of various devices in real time. The platform monitoring device 33 is disposed on the sea surface support subsystem 10 and is used to summarize the working conditions and environmental data of various devices for comprehensive monitoring.

[0062] Since the monitoring sensors are disposed on the hardware maintenance device 31 and the hardware and environmental monitoring device 32, the hardware maintenance device 31 and the hardware and environmental monitoring device 32 can be placed in the sea. Thus, the hardware maintenance device 31 and the hardware and environmental monitoring device 32 move along the extension direction of the pipeline transportation subsystem 20 in the water, enabling the monitoring sensors to detect the pipeline transportation subsystem 20 and the seabed mining subsystem 40. During the movement of the devices, the monitoring sensors monitor the pipeline transportation subsystem 20 and the seabed mining subsystem 40 in real time and can comprehensively monitor the pipeline transportation subsystem 20 and the seabed mining subsystem 40 to ensure the safety of the pipeline transportation subsystem 20 for transporting minerals and the seabed mining subsystem 40 for mining minerals. At the same time, the hardware maintenance device 31 performs real-time maintenance on the hardware of the pipeline transportation subsystem 20 and the seabed mining subsystem 40 to ensure the continuity and stability of the mining process. In addition, the platform monitoring device 33 is disposed on the sea surface support subsystem 10, so that the platform monitoring device 33 can summarize the working conditions and environmental data of various devices for comprehensive monitoring to ensure the safety and stability of the mining process.

[0063] It should be noted that the hardware maintenance device 31 and the hardware and environmental monitoring device 32 may be cruise robots. In addition, the monitoring sensors may include, but are not limited to, infrared sensors, cameras, turbidity sensors, environmental detectors, etc.

[0064] In addition, in some embodiments, the new green exploitation system for deep-sea sulfide resources may further include a platform monitoring device 33. The platform monitoring device 33 is disposed on the sea surface support platform 11. The platform monitoring device 33 is connected to the hardware maintenance device 31 and the hardware and environmental monitoring device 32. The platform monitoring device 33 is used to receive the detection information sent by the hardware maintenance device 31 and the hardware and environmental monitoring device 32 and issue a prompt message.

[0065] Since the platform monitoring device 33 is electrically connected to the hardware maintenance device 31 and the hardware and environment monitoring device 32, the hardware maintenance device 31 and the hardware and environment monitoring device 32 can send the detected information to the platform monitoring device 33 in real time. The platform monitoring device 33 can send out a prompt message according to the detected information, so as to prompt the operator, facilitate the operator to know the condition of the seabed environment, and protect the seabed environment.

[0066] Among them, after receiving the detected information, the platform monitoring device 33 can judge the detected information. If the value representing the seabed environment in the detected information is greater than the preset threshold, the platform monitoring device 33 will send out a prompt message. Specifically, the hardware maintenance device 31 and the hardware and environment monitoring device 32 can detect the detected value of the seabed environment and send the detected value to the platform monitoring device 33. When the platform monitoring device 33 determines that the detected value is greater than the preset threshold, it indicates that the seabed environment is polluted, and then the platform monitoring device 33 will send out a prompt message. It should be noted that the detected value includes but is not limited to the turbidity value, sulfide value, etc.

[0067] In addition, the prompt message can be a prompt sound. At this time, the platform monitoring device 33 includes a voice module; of course, the prompt message can also be an alarm light. At this time, the platform monitoring device 33 includes an alarm lamp. Of course, the platform monitoring device 33 can include a voice module and an alarm lamp at the same time, and the platform monitoring device 33 can send out both a prompt sound and an alarm light.

[0068] In the embodiment of the present application, since the pipeline transportation subsystem is connected to the seabed mining subsystem and the sea surface support subsystem is arranged on the sea surface, when it is necessary to mine the seabed, the seabed mining subsystem can be deployed on the seabed through the sea surface support system, and the seabed mining subsystem conducts closed mining. The minerals mined by the seabed mining subsystem can be transported to the sea surface support subsystem through the pipeline transportation subsystem, and the sea surface support subsystem is a semi-submersible platform. Compared with a sea surface support ship, continuous and stable mining of seabed minerals can be realized. That is to say, in the embodiment of the present application, by setting the sea surface support subsystem as a semi-submersible platform and the seabed mining subsystem conducting closed mining on the seabed, it can be ensured that during the process of mining minerals by the seabed mining subsystem, the pollution to the seabed environment is relatively small. After the minerals mined by the mining module are transported to the sea surface support subsystem through the pipeline transportation subsystem, the minerals are stored on the semi-submersible platform, which can effectively avoid the problems of small mineral storage capacity of ships and limited continuity of mining operations. At the same time, through the comprehensive maintenance and environment perception subsystem, real-time monitoring of equipment and mining environment during the mining operation can be carried out, and real-time maintenance of equipment can be carried out. That is to say, in the embodiment of the present application, when mining the seabed, not only the pollution to the seabed environment is relatively small, but also the continuity and stability of seabed mining can be realized.
