Description

Technical Field

[0001] The utility model relates to a deep - sea mineral transportation platform, in particular to a deep - sea mineral transportation platform integrating far - reaching and deep - sea wind power generation and temperature difference power generation. Background Art

[0002] The deep - sea mineral transportation system is the most technically difficult equipment system in the deep - sea mining field. At present, although European and American countries have completed the large - depth sea trial verification of the transportation system, proving the technical feasibility, generally speaking, it still remains at the experimental level, and has not effectively solved a number of problems such as complex large - depth and high - power power supply for pumps, difficult to guarantee long - term operation, etc., and cannot ensure the long - term reliable operation ability of the transportation system, and there is still a distance from commercialization.

[0003] At present, both of the two lifting device methods for deep - sea mining have a large demand for electricity, and can only be solved by power generation from surface ships, with a strong dependence on external supply, which is very uneconomical, and this is also one of the important factors affecting the promotion of commercialization. According to the development plan, far - reaching and deep - sea wind power generation and ocean thermal energy conversion have become one of the subsequent development directions of ocean resource development. Summary of the Invention

[0004] The utility model aims to propose a deep - sea mineral transportation platform integrating far - reaching and deep - sea wind power and temperature difference power generation. Aiming at problems such as high cost of far - reaching and deep - sea supply and uneconomical high - power power supply, it draws on the far - reaching and deep - sea floating platform wind power generation technology that is currently being promoted, integrates the transportation platform with the wind power generation platform, generates electricity nearby and uses it nearby to improve the economy of mining; at the same time, it will utilize the temperature difference between deep - sea pulp and sea - surface sea water for temperature difference power utilization, as the power supply required for aspects such as monitoring and living of the operating personnel of the transportation platform.

[0005] To achieve the above object, the technical solution of the utility model is: a deep - sea mineral transportation platform integrating far - reaching and deep - sea wind power generation and temperature difference power generation, including a wind power generation module, a makeup water pump, a mineral storage and external transportation area, an underwater pump pipe system, an operation and command area, a temperature difference power generation module, and a booster pump. The wind power generation module is connected to the makeup water pump, the mineral storage and external transportation area, the underwater pump pipe system, and the booster pump, and is used to utilize the offshore wind energy to supply power to the makeup water pump, the mineral storage and external transportation area, the underwater pump pipe system, and the booster pump; the underwater pump pipe system is connected to the temperature difference power generation module, and is used to discharge the tail water generated by the underwater pump pipe system to the temperature difference power generation module, so that the temperature difference power generation module generates electricity through the temperature difference between the tail water and the sea - surface water, and generates additional power supply to the operation and command area; the temperature difference power generation module is connected to the booster pump and the slurry pump of the underwater pump pipe system, and is used to utilize the remaining tail water after being pressurized by the booster pump to drive the slurry pump in the underwater pump pipe system to operate, realizing the recycling of the tail water.

[0006] Furthermore, the power generation of the wind power generation module is adapted to the power consumption of the deep-sea mineral transportation platform.

[0007] Furthermore, the power generation of the thermoelectric power generation module is adapted to the electricity demand of the staff for work and life on the deep-sea mineral transportation platform.

[0008] Furthermore, the underwater pump pipe system, the operation command area, the thermoelectric power generation module, and the booster pump constitute the tail water utilization functional area.

[0009] Furthermore, the make-up water pump and the booster pump form a seabed make-up water unit, which is used to pressurize deep-sea seawater through the make-up water pump and the booster pump as the driving source of the hydraulic-driven slurry pump in the underwater pump pipe system.

[0010] Furthermore, the mineral storage and external transportation area and the underwater pump pipe system form a slurry transportation unit, which is used to pump deep-sea minerals to the mineral transportation platform through the underwater pump pipe system and then store or transport them externally through the mineral storage and external transportation area.

[0011] Advantages of the present utility model:

[0012] A deep-sea mineral transportation platform integrating far-reaching offshore wind power generation and thermoelectric power generation according to the present utility model combines wind power generation, thermoelectric power generation and far-reaching offshore mining operations, generates electricity nearby and uses it nearby, reduces the difficulty of power grid connection, and improves work economy. The following main advantages are generated:

[0013] 1. When the platform conducts far-reaching offshore mining and transportation work, the wind power generation module utilizes the offshore wind energy to supply power to the make-up water pump, the mineral storage and external transportation area, the underwater pump pipe system, and the booster pump, providing the necessary power for the operation of the mineral transportation platform, driving the operation of each unit of the platform, generating electricity nearby and using it nearby, and improving the economy of mining operations;

[0014] 2. When the underwater pump pipe system generates tail water during the slurry collection process, the tail water is discharged to the thermoelectric power module, and electricity is generated through the temperature difference between the tail water and the sea surface seawater. The generated electricity is supplied to the operation command area for the basic electricity required for the platform staff to monitor work and life. The remaining tail water after power generation is discharged to the booster pump again, and together with the make-up water pumped by the make-up water pump, it is pressurized and reused by the underwater pump pipe system to provide the power required for the operation of the water-driven slurry pump in it, further improving the green environmental protection and economy of mining operations.

[0015] Generally speaking, the deep-sea mineral transportation platform integrating far-reaching offshore wind power generation and thermoelectric power generation solves the basic electricity demand for the operation of the far-reaching offshore mining platform by generating electricity nearby and using it nearby through the wind power generation module. Combining with the thermoelectric power generation module, it utilizes the temperature difference energy between the tail water of the pump pipe system and the sea surface seawater to generate electricity, provides the basic electricity for the life of the operators, reduces the difficulty of grid connection after power generation, and brings a new green environmental protection model for deep-sea resource development.
