Control system and method for ground clearance of hydraulic collecting mechanism and multi-metal concretion mining vehicle

Abstract

The invention discloses a control system and method for the ground clearance of a hydraulic collecting mechanism and a multi-metal concretion mining vehicle and belongs to the field of machinery automatic control. The control system comprises a parallelly-moving mechanism, the hydraulic collecting mechanism and two sets of ground clearance measuring mechanisms. The two sets of ground clearance measuring mechanisms are fixed to the two sides of the hydraulic collecting mechanism correspondingly and used for measuring the ground clearance of the hydraulic collecting mechanism, one end of the parallelly-moving mechanism is hinged to the hydraulic collecting mechanism and used for adjusting the ground clearance of the hydraulic collecting mechanism, and the other end of the parallelly-moving mechanism is hinged to the front end of the mining vehicle. According to the control system and method for the ground clearance of the hydraulic collecting mechanism and the multi-metal concretion mining vehicle, the ground clearance of the hydraulic collecting mechanism can be adjusted in real time to enable the ground clearance to be kept within the suitable range, and the multi-metal concretioncollection efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of mechanical automatic control, in particular to a control system, a control method and a polymetallic nodule mining vehicle for the height of a hydraulic collection mechanism from the ground. Background technique [0002] Among the mining techniques and methods of mineral resources such as deep-sea polymetallic nodules, hydraulic mining is a promising technique and method. It has the advantages of simple structure, low failure rate, and less disturbance to the seabed environment. However, it has a certain range of requirements for the height above the ground. If the height above the ground is too high or too low, the collection rate of the hydraulic collection mechanism will be seriously affected. [0003] When the hydraulic collection mechanism collects polymetallic nodules on the deep seabed, due to the change of seabed topography, the height above the ground will also change accordingly. Once the change of the he...
