Clustering type deep seafloor mineral collection equipment based on vortex hydrodynamic characteristic

Abstract

The invention relates to seafloor mineral collection equipment which comprises an equipment main body, multiple adaptive seafloor mineral collectors and respective mineral conveying pipes, wherein the equipment main body is connected with the adaptive seafloor mineral collectors through the mineral conveying pipes, and the lengths, extending out of the equipment main body, of the mineral conveying pipes can be controlled to be regulated; the adaptive seafloor mineral collectors are provided with crawler walking mechanisms, and can be controlled to walk independently. According to the equipment, the seafloor topography and mineral distribution in the vicinity of an operation region are detected by virtue of an underwater detector, and the advancing path of the seafloor mineral collectors and a mineral storage vehicle is reasonably planned according to detected information; the multiple adaptive seafloor mineral collectors independently work at the same time, so that the mineral collectors are light and miniature, and damage of mineral collection operation to the ecological environment of the seafloor is reduced; by the equipment main body, a relatively flat seafloor path can be selected, and a rough path can be avoided; horizontal eddy flows are induced by the mineral collectors to facilitate enhancement of a mineral collection effect and improvement of suction force of unit energy consumption, so that a smaller number of water pumps with smaller sizes are required, the size of a mineral collection main unit is reduced, the energy consumption is further greatly reduced, and the equipment is more environment-friendly.

Description

technical field [0001] The invention relates to a seabed ore gathering equipment, in particular to an intelligent and collaborative seabed ore gathering equipment. Background technique [0002] The ocean is the largest potential resource base on the earth that has not been fully understood and utilized by humans. In addition to offshore oil and gas resources and coastal mineral sands, the seabed is currently known to have commercial mining value as well as metal mineral resources such as polymetallic nodules, cobalt-rich crusts and polymetallic sulfides. These minerals are rich in nickel, cobalt, copper, manganese, gold and silver metals, etc., and the total reserves are dozens to thousands of times higher than the corresponding reserves on land. In 2013, my country officially obtained a Pacific cobalt-rich crust mining area. Obviously, the development of deep sea mineral resources must rely on deep sea mining equipment. The "Made in China 2025" announced on May 19, 2015 ...

AI Technical Summary

Problems solved by technology

[0005] The integrated structure of the mining device and the main body has certain requirements for the walking road of the equipment (not too rough), which has a negative impact on the scope of mining;

[0006] In order to ensure a certain mining efficiency, the walking speed of the equipment is forced to increase, which affects the controllability and reliability of the equipment;

[0007] The adsorption capacity of the ore collector is relatively weak. The publication date is February 24, 2016, and the publication number is the Chinese patent document CN105350968A, which discloses a kind of seabed ore collection vehicle. As for the water jet nozzle, it can be seen from the accompanying drawings that the spiral deflector does not cooperate well with the water jet nozzle, and the effect of this type of spiral deflector on improving the adsorption force is also very limited; in addition , the sealing of the suction cover is insufficient, which will also lead to insufficient adsorption capacity;

[0008] When the ore collector moves with the main body, it is easy to collide with ore or other obstacles. The ore collector must be lifted upwards to avoid obstacles, resulting in insufficient suction. When the avoidance is not timely, the collision will cause certain damage to the ore collector;

[0009] Due to the complex underwater terrain, when the existing seabed ore gathering equipment travels, the detection of the complex underwater terrain is insufficient, and the detection of mineral distribution is also insufficient, which affects the correct guidance and judgment of the travel path, and also affects the avoidance of high-risk operation areas. open
