Self-rescue device and self-rescue method for submerged ore-collecting vehicle submerged during walking

Abstract

The invention discloses a self-rescue device for subsidence and escape during the walking process of a seabed ore collecting vehicle. The inner cavity of the track traveling device is equipped with a hydraulic control device and a power wheel that can be extended and retracted horizontally. The soil shifting gear is fixedly installed on the outer circumference of the power wheel. Universal joint, under the control of the hydraulic control device, the hydraulic rod pushes the support plate to expand from the vertical state to the horizontal state. After the power wheel stretches out horizontally, the earth moving gear is just in the elongated hole of the support plate. The invention also discloses a self-rescue method utilizing the self-rescue device at the same time. The method and device can realize the self-rescue and escape of the ore-collecting vehicle after subsidence, break away from the subsidence area, reduce the ore leakage rate, and ensure the continuous operation of mining and ore-collecting work.

Description

technical field [0001] The invention relates to a deep-sea mining operation technology, in particular to a self-rescue device and a self-rescue method for subsidence of a seabed mine collection vehicle during walking. Background technique [0002] The deep seabed is rich in solid ore resources such as polymetallic nodules, polymetallic sulfides, and cobalt crusts. The proven reserves are tens of billions of tons, which is an important direction to solve the global resource and energy shortage. [0003] The occurrence environment of polymetallic nodule resources in the deep ocean is harsh, and the polymetallic nodule resources are distributed in an area, with an area enrichment degree of about 6-10 kg / m 2 , occurs scattered, and only occurs in the rare soft soil on the surface of 0~25cm on the seabed, the shear strength of the existing soil is low (0~6kPa), and the bearing capacity is poor. The jet flow in front of the mining vehicle breaks the ground for mining, and the rar...

Problems solved by technology

However, the process is complicated, and once the area of ​​the subsidence area is too large, it will greatly affect the efficiency of travel, and due to the process of breaking the soil, the subsidence area often coincides with the location of the mining area. This design cannot be carried out simultaneously in the process of making the mine collection vehicle leave the subsidence area. Mineral collection, which will cause great waste and seriously affect the efficiency of mining ore collection
