Skidding-state monitoring device can be used for deep-sea mining vehicle, deep-sea mining vehicle and skidding monitoring method

Abstract

The invention discloses a skidding-state monitoring device can be used for a deep-sea mining vehicle, the deep-sea mining vehicle and a skidding monitoring method. The skidding-state monitoring device comprises a control device, a track speed measuring device and a speed measuring land wheel; the track speed measuring device is mounted on a track driving wheel of the deep-sea mining vehicle and connected with the control device through an underwater cable and a watertight connecting piece; the speed measuring land wheel is mounted at the tail of the deep-sea mining vehicle and is hinged through a shaft, and the speed measuring land wheel is used for measuring the running speed relative to the seabed ground of the deep-sea mining vehicle; and the speed measuring land wheel is connected with the control device through the underwater cable and the watertight connecting piece. According to the skidding-state monitoring device, the skidding state of the deep-sea mining vehicle can be judged, and corresponding treating measures can be given to solve the existing technical problem that the deep-sea mining vehicle cannot monitor and judge the skidding state.

Description

technical field [0001] The invention relates to the field of deep sea mining, in particular to a slip state monitoring device applicable to a deep sea mining vehicle, a deep sea mining vehicle and a slip monitoring method. Background technique [0002] Polymetallic nodules are an important mineral resource in the ocean, containing dozens of metals such as manganese, iron, nickel, cobalt, and copper, and have a huge storage capacity. It is estimated that the world's seabed polymetallic nodule resources are 3 trillion tons. Polymetallic nodules generally occur in water of 3,000 to 6,000 meters, and the substrate is thin and soft with low shear strength. [0003] Because the deep seabed is thin and soft and the shear strength is low, the biggest difficulty for various driving mechanisms to walk on the seabed is that it is prone to slipping and subsidence. The current mining vehicle traveling mechanism generally adopts a crawler structure. Slight skidding does not affect the w...
