Description

Technical Field

[0001] This utility model relates to the field of deep-sea mining technology, and in particular to a self-sinking and floating deep-sea mining mineral lifting device. Background Technology

[0002] Subsea mineral lifting systems are a key component of deep-sea mining, used to elevate extracted minerals or other deep-sea resources from the seabed to the surface. This process involves complex engineering and technological challenges. The following are some of the main problems faced by subsea mineral lifting systems:

[0003] (1) High pressure and water pressure in the deep sea: The seabed is usually very deep, resulting in extremely high water pressure. Designing a mining lifting system that can withstand high water pressure is a challenge because water pressure increases dramatically with depth; (2) Material strength and corrosion resistance: Mining lifting systems need to use corrosion-resistant materials to cope with the corrosive effects of seawater. In addition, these materials need to have sufficient strength to resist water pressure and withstand the forces during the lifting process; (3) Power requirements: Lifting minerals from the deep seabed to the surface requires a large amount of energy. Determining a reliable and efficient power system and adopting a power solution that meets environmental standards is a challenge; (4) Stability during the lifting process: The seabed mining lifting system needs to remain stable during the lifting process to avoid damage to the minerals or system failure. This may involve intelligent control systems, adaptive technologies, and advanced sensors to ensure smooth operation; (5) Treatment of mining waste: Waste generated during the lifting process needs to be effectively treated to avoid negative impacts on the deep-sea ecosystem. An effective waste management system is an important component of protecting the marine environment; (6) Regulatory and environmental issues: Seabed mining activities need to comply with strict international regulations and environmental standards to ensure that the design and operation of the ore hoisting system complies with these regulations and minimizes the impact on the marine ecosystem. Therefore, the existing technologies for ore recovery schemes after mining in deep-sea mining are complex and unstable, making it difficult to achieve efficient ore hoisting and recovery.

[0004] In view of this, the current design of the seabed mineral extraction system engineering still needs further improvement. Utility Model Content

It can carry deep-sea seabed minerals and achieve free movement between the seabed and the sea surface, thereby realizing the recovery of seabed minerals.

[0025] Meanwhile, the self-floating deep-sea mining mineral lifting device described in this utility model has significantly reduced costs and improved system stability compared to current deep-sea mining lifting systems. Compared to the pump lifting method in traditional deep-sea mining solutions, it eliminates the need for moving parts such as ultra-large pumps and deep-sea mineral lifting pipelines, reducing system complexity and improving system stability.

[0026] Because traditional solutions use large booster pumps and subsea pipeline systems, which can easily cause significant environmental noise pollution to the ocean, this design adopts a small modular design to reduce the impact of mineral extraction. Attached Figure Description

[0079] Example 3

[0080] A self-floating deep-sea mining mineral hoisting device, the working process of which includes the following steps:

[0081] Step 100: Fill the water storage tank 31 with water. When the water is stored, it helps to provide gravity to the main body 1, ensuring that the weight of the instrument is greater than the buoyancy.

[0082] Step 200: Using the shipborne crane and the deployment and recovery hook 73, the deep-sea mining mineral lifting device is placed into the seawater and sinks under its own weight after being unhooked.

[0083] Step 300: The deep-sea mining lifting device begins to sink under its own weight.

[0084] Step 400: With the cooperation of the shipborne underwater acoustic communication unit, the underwater acoustic communication and positioning system of the seabed mining transport device, and the underwater acoustic communication unit of the mining vehicle, and under the action of the power unit 5, the deep-sea mining mineral hoisting device completes the docking of the mineral bin device 2 with the seabed mining vehicle.

[0085] Step 500: The seabed mining vehicle loads ore into the mining bin unit 22 of the mining bin device 2. At the same time, the high-pressure pump 32 controls the water volume of the water storage bin 31 and adjusts the drainage state of each water storage bin 31, thereby providing buoyancy for the main body 1, enabling it to float at a constant depth on the seabed and move with the mining vehicle under the action of the power unit 5.

[0086] Step 600: After the ore bin unit 22 is filled with ore, water is pumped out by the high-pressure pump 32 to make the weight of the deep-sea mining ore lifting device less than the buoyancy, and the deep-sea mining ore lifting device begins to float upward.

[0087] Step 700: After surfacing, the communication and positioning device is used to locate and retrieve the deep-sea mining lifting device, recover the ore, replace or recharge the battery, and then deploy it again.

[0088] Example 4

[0089] like Figure 4 The diagram shows a schematic block diagram of the control system connection structure of the autonomous floating deep-sea mining ore hoisting device of this utility model. The high-pressure pump in the buoyancy control device, combined with the control box in the electronic device, forms a water storage control system. This system controls the water level in the storage tank to adjust buoyancy and controls the ore bin unit within the ore bin device to collect and store seabed ore. The power device serves as a power supply system, electrically connected to the recovery unit (as a recovery unit) and the propulsion system (as a propulsion system), providing energy to both. Finally, the communication and positioning device is fixed above the main body to form a communication and positioning system. This system enables communication and positioning with the mining vehicle matched to the ore bin unit, and provides positioning functionality for the autonomous floating deep-sea mining ore hoisting device during recovery.

[0090] like Figure 5 The diagram shown illustrates the operational flow of the self-sinking and floating deep-sea mining lifting device of this invention after assembly. After water is filled in the storage tank, the weight of the self-sinking and floating deep-sea mining lifting device exceeds its buoyancy. This causes the entire system to sink. The device then locates the mining truck via a communication and positioning device, docks with the seabed mining truck, and loads ore. During this process, the water storage capacity in the storage tank is continuously adjusted to ensure the self-sinking and floating deep-sea mining lifting device maintains a stable position on the seabed and continues loading ore. Finally, once the ore bin is full, all water is drained from the storage tank, causing the self-sinking and floating deep-sea mining lifting device to float. A recovery device locates the floating device and retrieves it. This process is repeated after unloading all the ore, enabling free movement between the seabed and the surface. This reduces the cost of the deep-sea mining lifting system, improves system stability, and enables efficient and stable seabed mineral recovery.

[0091] In summary, this utility model provides a self-sinking and floating deep-sea mining mineral lifting device, including a main body forming the overall frame of the self-sinking and floating deep-sea mining mineral lifting device; a mineral bin device disposed at the bottom of the main body for collecting and storing ore; a buoyancy control device fixedly disposed inside the main body, which adjusts the buoyancy of the main body by sucking in or expelling seawater to achieve self-sinking and floating of the self-sinking and floating deep-sea mining mineral lifting device; and a power device fixedly disposed inside the main body, which provides power to the mineral bin device and the buoyancy control device to adjust the buoyancy. The self-sinking and floating deep-sea mining mineral lifting device of this invention utilizes seawater as a buoyancy adjustment medium by setting up a buoyancy control device. Buoyancy is adjusted by drawing in and expelling seawater, enabling vertical movement in the sea. Simultaneously, it is equipped with an underwater parallel propulsion system as the power system and a deep-sea positioning system as the seabed mineral positioning system, together forming a highly efficient and stable deep-sea mining transportation system. This system can carry deep-sea seabed minerals, enabling free movement between the seabed and the surface, thus facilitating seabed mineral recovery. Compared to current deep-sea mining lifting systems, the cost is significantly reduced, and system stability is improved. Compared to traditional deep-sea mining solutions using pump lifting, it eliminates the need for large pumps, deep-sea mineral lifting pipelines, and other moving parts, reducing system complexity and improving system stability.
