Hydraulic power type collection mechanism

Abstract

The invention discloses a hydraulic power type collection mechanism. The hydraulic power type collection mechanism comprises a submarine mining vehicle, a collecting and conveying pipeline and a separation device. A suction inlet is arranged at the front end of the collecting and conveying pipeline. The separation device is connected with a rear output outlet of the collecting and conveying pipeline. Disturbance nozzles are arranged on the front side and the rear side of the suction inlet respectively. A delivery nozzle used for spraying delivered water flow is arranged in the collecting and conveying pipeline. The collecting and conveying pipeline is mounted on the submarine mining device through an adaptive topography compensation device in an up-down floating mode. Sliding plates used for supporting the collecting and conveying pipeline on the surfaces of submarine sediments are arranged on the collecting and conveying pipeline and are positioned below the suction inlet. A gap is reversed between each sliding plate and the suction inlet in the vertical direction. The hydraulic power type collection mechanism has the advantages of high collection efficiency, stability and reliability in working, small environmental disturbance, capability of adapting to submarine topographic environments and geological environments and the like.

Description

technical field [0001] The invention relates to the technical field of seabed engineering operation equipment, in particular to a hydraulic collection mechanism suitable for seabed multi-metal combined collection. Background technique [0002] Manganese nodules mainly occur in the surface layer of seabed sediments with a water depth of 3000-6000m and low bearing capacity and shear strength, and the thickness of the sediments can reach hundreds of meters or even hundreds of meters. According to preliminary survey estimates, the total reserves are about 3 trillion tons, of which about 70 billion tons have industrial exploitation value, and the annual growth rate is about 10 million tons. Deep-sea manganese nodule mining is a high-tech-intensive field, and its mining system is a huge and complex system engineering, and ore collection and lifting are the core technology and key components of the mining system. [0003] Due to its simple structure, reliable operation, high colle...

AI Technical Summary

Problems solved by technology

When the topography of the seabed changes and the shear strength of the sediment changes greatly, the mechanism cannot maintain the height of the suction inlet of the follow-up collection channel well, and there are deficiencies such as low collection efficiency and more sediment inhalation; the delivery nozzle is located at the collection The upper part of the conveying channel causes the lower part of the collection and conveying channel to form a low-velocity zone, causing larger nodules to accumulate at the collection suction port, causing blockage or inability to transport efficiently
