Cluster type submarine mining collector based on eddy hydrodynamic characteristic

Abstract

The invention relates to a detecting device and method for all-around hydrodynamic detection of a mining collector. A cluster type submarine mining collector based on the eddy hydrodynamic characteristic comprises a device body, multiple submarine adaptive mining collectors and respective ore conveying pipes. The ore conveying pipes enable the device body to be connected with the submarine adaptive mining collectors. The ore conveying pipes can be controlled to adjust the length of extending out of the device body. Each submarine adaptive mining collector is provided with a crawler walking mechanism and can be controlled to conduct autonomous walking. An underwater detector is utilized to detect the submarine topography and mineral distribution nearby the operation area, and the advancingpaths of the submarine mining collectors and an ore storage car are reasonably made according to detected information; the multiple submarine adaptive mining collectors can simultaneously and independently work, the mining collectors are lightened and miniaturized, and the damage of the mining collecting operation to the submarine ecological environment is reduced; the device body can select relative flat submarine path and avoid a rugged path; the mining collectors induce horizontal spiral flow, so that the mining collecting effect is enhanced beneficially, the suction force of per unit energy consumption is improved, and therefore less water pumps with smaller sizes are configured; and in this way, the main size of each mining collector is reduced, so that the energy consumption is greatly lowered, and the environmental protection performance is better.

Description

technical field [0001] The invention relates to a detection device and a detection method for all-round hydrodynamic detection of an ore collecting machine, in particular to an intelligent cooperative seabed ore collecting 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 ...

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
