Disclosure of Invention
In accordance with the above technical problem, there is thus provided a deep sea mining system.
A deep sea mining system comprises a water surface supporting ship and a submarine mining vehicle, wherein a water inlet of an ore collecting box of the submarine mining vehicle is connected with one end of a conveying hose, the other end of the conveying hose is connected with a conveying pump installed on the water surface supporting ship, an ore outlet of the ore collecting box of the submarine mining vehicle is connected with one end of a lifting hose, and the other end of the lifting hose is connected with a lifting pump installed on the water surface supporting ship;
the conveying pump conveys seawater into an ore collection box of the submarine mining vehicle through the conveying hose, the seawater is mixed with mineral resources in the ore collection box, and the lifting pump lifts the seawater mixed with the mineral resources to the water surface support ship through the lifting hose.
The invention adopts two hoses, namely the conveying hose and the lifting hose, to be directly connected with the submarine mining vehicle, and does not need a middle bin and a hard pipe and a moon pool, thereby increasing the lowering speed of the submarine mining vehicle. At the same time, the transfer pump and the lift pump are both arranged on the surface support vessel, which facilitates maintenance and replacement even if the pump is damaged, without having to perform maintenance after lifting the subsea mining vehicle/intermediate bin from the seabed.
Further, a terrain detection device is mounted on the subsea mining vehicle for detecting the subsea terrain and transmitting signals to the surface support vessel. The seabed situation is reflected to the water surface supporting ship in time, and the lifting of the seabed mining vehicle is prepared in time.
Further, a conveying hose lowering system and a lifting hose lowering system are installed on the water surface support ship;
the conveying hose lowering system is used for lowering and recovering the conveying hose;
the lifting hose lowering system is used for lowering and recovering the lifting hose.
When the submarine mining vehicle is lowered, the bottom end of the conveying hose and the bottom end of the lifting hose are connected with the submarine mining vehicle, then the hoses are placed through the conveying hose lowering system and the lifting hose lowering system, and the submarine mining vehicle descends. When the subsea mining vehicle needs to be lifted, the upper ends of the conveying hose and the lifting hose are detached from the conveying pump and the lifting pump, then the conveying hose and the lifting hose are placed on the conveying hose lowering system and the lifting hose lowering system, the bottom end of the hose is lifted upwards, and the subsea mining vehicle is lifted.
Further, the conveying hose transfer system and the lifting hose transfer system are the same in structure and both comprise: the hose winch is used for winding and unwinding a lifting hose or a conveying hose wound on the hose winch, the guide device is used for guiding the lifting hose and the conveying hose, and the tensioner is used for limiting the descending or lifting speed of the lifting hose or the conveying hose. The hose is wound on a hose winch, the tensioner tightens the hose to adjust the hose releasing or retracting speed, and then the hose is connected with the seabed mining vehicle through the guiding device.
Furthermore, tension and angle monitors are installed at one ends of the conveying hose and the lifting hose in the sea and are used for monitoring the tension and the angle of the conveying hose and the lifting hose. The state is reflected to the water surface support ship in time so as to adjust the tension and the angle of the hose under the action of the conveying hose lowering system and the lifting hose lowering system, and the hose is prevented from being damaged.
Furthermore, a cable for providing energy for the submarine mining vehicle is arranged on one side of the conveying hose, and an auxiliary winch for winding and unwinding the cable is installed on the water surface supporting ship.
Furthermore, a separation system is installed on the water surface support ship close to the lifting hose, and the separation system is used for separating mineral resources and seawater.
Furthermore, buoyancy blocks are mounted at one ends, located in the sea, of the conveying hose and the lifting hose. The buoyancy block provides buoyancy for the conveying hose and the lifting hose, and the conveying hose and the lifting hose are prevented from contacting with the seabed.
Compared with the prior art, the invention has the following advantages:
the invention adopts the proposal that the conveying hose and the lifting hose are respectively connected with the submarine mining vehicle for mining, because a full hose model is used, the lowering speed is increased, and because of the characteristics of the hose, the invention has strong adaptability to different sea areas and water depths; the submarine mining vehicle, the conveying hose and the lifting hose are connected on the water surface support ship, and the connection is not needed to be carried out on the seabed by using an ROV; meanwhile, the conveying pump and the lifting pump are arranged on the water surface supporting ship, when the pump fails, the pump is quite convenient to detect and maintain, and the submarine mining vehicle/the intermediate bin does not need to be recovered to the water surface for detection and maintenance; the requirement on the water surface support ship is not high, and a moon pool does not need to be arranged; when the submarine mining vehicle encounters an obstacle or needs to change a mining area for mining, because the obstacle avoidance capability of the submarine mining vehicle is not strong and the walking speed is too slow, the submarine mining vehicle in the scheme can directly recover a certain height through the conveying hose lowering system and the lifting hose lowering system, and is integrally linked under the action of the water surface support ship, so that the speed is increased, and the damage to the submarine mining vehicle is also reduced.
Based on the reasons, the invention can be widely popularized in the fields of deep sea mining and the like.
