A subsea polymetallic nodule in situ abundance measurement vehicle

Abstract

The invention discloses an in-situ abundance measurement vehicle for seabed polymetallic nodules, comprising a frame, a seabed traveling device and an abundance sampling evaluation device. The frame is installed on the seabed traveling device, and the abundance sampling evaluation device is installed on the vehicle. On the shelf, the abundance sampling and evaluation device includes a material bin, a nodule collecting device for collecting polymetallic nodules on the seafloor, and a nodule flushing device for flushing the polymetallic nodules in the nodule collecting device to different bins in the material bin. The abundance measurement vehicle of the present invention can automatically travel to the target area after it is deployed on the seabed, completely avoiding the problems of inaccurate deployment and time-consuming deployment caused by traditional deployment difficulties; further, the abundance measurement vehicle passes through a single deployment. The metal nodules are transported to different silos in the material silo under the action of water pressure, which can not only effectively complete the transportation of nodule materials, but also clean the nodules.

Description

technical field [0001] The invention relates to the technical field of deep-sea mining equipment, in particular to an in-situ abundance measuring vehicle for seabed polymetallic nodules. Background technique [0002] Submarine polymetallic nodules are mostly found on the seabed with a water depth of 3000-6000m. They are a very important seabed mineral resource. They contain 76 kinds of metal elements such as manganese, copper, nickel and cobalt. They are mineral resources that are in short supply on land. Commercial mining will greatly alleviate the problem of lack of mineral resources on land. Before mining, parameters such as coverage, particle size and abundance of polymetallic nodules on the seafloor need to be evaluated to illustrate the occurrence of polymetallic nodules on the seafloor. [0003] At present, the exploration of deep-sea polymetallic nodules minerals is still in the stage of exploration. Since they are generally distributed on the seabed surface in gran...

Problems solved by technology

However, since neither of them has the function of measuring all parameters, and the optical detection only estimates the coverage and particle size based on image and video data, the error is relatively large; there are few measurement points in the box sampling exploration, and the single operation time It is difficult to systematically evaluate the distribution of nodules due to shortcomings such as point length
