Abstract

The invention discloses a heave compensation simulation test device for deep-sea mining. The outer ring of a gimbal frame device (2) is connected with the upper platform of a mining ship movement simulator (1); the inner ring of the gimbal frame device (2) is connected with an active heave compensation device (3); an attitude sensor (6) is mounted on the upper platform of the mining ship movement simulator (1); a cylinder displacement sensor (7) is mounted on the cylinder of the mining ship movement simulator (1); a heave compensation device displacement sensor (5) is connected with the active heave compensation device (3); a simulation pipe system (4) is connected with the active heave compensation device (3); the signal output ends of the attitude sensor (6), the cylinder displacement sensor (7) and the heave compensation device displacement sensor (5) are connected with the input end of a controller (8); and the output end of the controller (8) is connected with the control ends of the mining ship movement simulator (1) and the active heave compensation device (3). The invention can achieve the performance testing of the heave compensation simulation test device for deep-sea mining, thereby providing the basis for the design of the heave compensation system for deep-sea mining.

Description

technical field [0001] The invention relates to a simulation test device for heave compensation in deep sea mining, in particular to a simulation test device for a heave compensation device for a pipeline lifting mining system. Background technique [0002] Pipeline lifting deep sea mining system is generally composed of ore collection subsystem, ore lifting pipeline subsystem and water surface support subsystem, etc. The hoisting pipe moves along with the mining ship, which will cause the longitudinal vibration of the hoisting pipe, which will lead to fatigue damage of the hoisting pipe, which seriously affects the stability, reliability and service life of the hoisting pipe and the working performance of the seabed ore collection vehicle. Stability, which in turn directly affects the efficiency and economy of the entire mining system. Therefore, it is necessary to study and design the heave compensation device to slow down the impact of the mining ship's movement on the m...
