Description

Technical Field

[0001] The invention relates to the technical field of deep-sea mining, and in particular to an autonomous sinking and floating deep-sea mining mineral lifting device. Background Art

[0002] Seabed mineral lifting systems are a key component of deep-sea mining. They are used to lift the collected minerals or other deep-sea resources from the seabed to the surface. This process involves complex engineering and technical challenges. The following are some of the main issues faced by seabed mineral lifting systems:

[0003] (1) High pressure and water pressure in the deep sea. The water depth at the bottom of the sea is usually very large, resulting in extremely high water pressure. Designing a lifting system that can withstand high water pressure is a challenge because water pressure increases dramatically with depth. (2) Material strength and corrosion resistance. The lifting system needs to use corrosion-resistant materials to cope with the corrosive effects of seawater. In addition, these materials need to be strong enough to resist water pressure and withstand the forces during the lifting process. (3) Power requirements: It takes a lot of energy to lift minerals from the deep seabed to the surface. It is a challenge to determine a reliable and efficient power system and adopt a power solution that meets environmental standards. (4) Stability during the lifting process: The seabed mineral 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: The 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 part of protecting the marine environment; (6) Regulations and environmental issues: Seabed mining activities need to comply with strict international regulations and environmental standards, ensure that the design and operation of the lifting system comply with these regulations, and minimize the impact on the marine ecosystem. Therefore, the existing technology for the recovery of ore after mining in deep-sea mining has a complex overall system and poor stability, making it difficult to achieve efficient ore lifting and recovery.

[0004] In view of this, the current design of seabed mineral lifting system engineering needs to be further improved. Summary of the invention

[0005] In view of this, the present invention proposes an autonomous sinking and floating deep-sea mining mineral lifting device, which solves the technical problems of complex and poor stability of large lifting pump systems in existing seabed mineral lifting systems.

[0006] The technical solution of the present invention is achieved in this way:

[0007] The present invention provides an autonomous sinking and floating deep-sea mining mineral lifting device, comprising:

[0008] A body, which forms the overall framework of the autonomous sinking and floating deep-sea mining mineral lifting device;

[0011] An electric device is fixedly arranged inside the main body to provide electric power for the ore bin device and the buoyancy control device.

[0012] In one embodiment, the autonomous sinking and floating deep-sea mining mineral lifting device further comprises a power device, which is arranged around the body to provide power for the movement of the autonomous sinking and floating deep-sea mining mineral lifting device in the deep sea.

[0013] In one embodiment, the buoyancy control device comprises:

[0014] A water storage tank, the water storage tank is fixed inside the body, and the buoyancy of the autonomous sinking and floating deep-sea mining mineral lifting device is adjusted by adjusting the water storage amount in the water storage tank;

[0015] A high-pressure pump is fixed inside the electric device and connected to the water storage tank to regulate the pressure of the water storage tank.

[0016] In one embodiment, the water storage bin is a cylindrical structure, and a plurality of the water storage bins are symmetrically distributed in the body.

[0017] In one embodiment, the electric device is a sealed cylindrical structure, and the water storage tank is arranged parallel to the electric device and surrounds the electric device.

[0018] In one embodiment, the electric power device is provided with: a motor, a control box, a water outlet pipe, a water inlet pipe, a power supply interface and a hydraulic oil tank.

[0019] In one embodiment, the power device includes a vertical power device and a horizontal power device to provide vertical thrust and horizontal thrust respectively.

[0020] In one embodiment, the ore bin device includes a mine car docking device and a plurality of ore bin units.

[0021] In one embodiment, the autonomous sinking and floating deep-sea mining mineral lifting device also includes: a communication positioning device, which is fixed above the main body and electrically connected to the power device, and is used to achieve communication connection between the mine car docking device in the mine bin device and the mining car.

[0022] In one embodiment, the autonomous sinking and floating deep-sea mining mineral lifting device further comprises: a recovery device, wherein the recovery device comprises a beacon and a strobe for realizing the search and recovery of the autonomous sinking and floating deep-sea mining mineral lifting device.

[0023] The present invention is an autonomous sinking and floating deep-sea mining mineral lifting device, comprising: a body, a ore bin device, a buoyancy control device and an electric device, which has the following beneficial effects compared with the prior art:

[0024] Using seawater as a buoyancy regulating medium, the system weight and buoyancy are adjusted by injecting and removing seawater from the pressure chamber to achieve vertical movement of the vertical deep-sea mineral handling system. The buoyancy is adjusted by setting a buoyancy control device. At the same time, it is equipped with underwater parallel power propulsion and deep-sea positioning systems, which together constitute an efficient and stable deep-sea mining and transportation system that can carry deep-sea seabed minerals and realize free shuttle between the seabed and the sea surface, thereby realizing the recovery of seabed minerals;

[0025] At the same time, the autonomous sinking and floating deep-sea mining mineral lifting device of the present invention has a significantly reduced cost compared to the current deep-sea mining lifting system, and improves the system stability. Compared with the pump lifting method in the traditional deep-sea mining solution, it does not require super-large pumps, deep-sea mineral lifting pipelines and other moving parts, which reduces the complexity of the system and improves the stability of the system.

[0026] Since the traditional solution uses large lifting pumps and submarine pipeline systems, which easily cause greater environmental noise pollution to the ocean, this design adopts a small modular design to reduce mineral lifting. BRIEF DESCRIPTION OF THE DRAWINGS
