CLUSTERED DEEP SEABED MINERAL COLLECTION DEVICE BASED ON VORTEX HYDRODYNAMIC CHARACTERISTIC

摘要

Disclosed is a seabed mineral collection device, comprising a device body, multiple adaptive seabed mineral collectors (10), and respective mineral conveying pipes (9). The mineral conveying pipes (9) connect the device body to the adaptive seabed mineral collectors (10). Each mineral conveying pipe (9) can be controlled to regulate the length of the mineral conveying pipe (9) extending out of the device body. Each adaptive seabed mineral collector (10) is provided with a track walking mechanism and can be controlled to walk independently. The seabed topography and mineral distribution in the vicinity of an operation region are detected by means of an underwater detector, and the traveling path of the seabed mineral collectors (10) and a mineral storage vehicle can be applicably planned according to detected information. The multiple seabed mineral collectors (10) independently work at the same time, so that the mineral collectors are light and miniature, thereby reducing damage of a mineral collection operation to the seabed ecological environment. A relatively flat seabed path can be selected for the device body and a rough path is avoided. Horizontal spiral flows are induced by the mineral collectors to enhance the mineral collection effect and improve the suction force of unit energy consumption, so that a smaller number of water pumps with smaller sizes are required, the main dimensions of the mineral collectors are reduced, the energy consumption is greatly reduced, and the device is more environment-friendly.
