Title:
DEEP-SEA MINING FIELD ORE-RAISING PIPE LIFTING/LOWERING COMPENSATION SYSTEM AND COMPENSATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/139305
Kind Code:
A1
Abstract:
A deep-sea mining field ore-raising pipe lifting/lowering compensation system. The lifting/lowering compensation system comprises a mining vessel (1), a dynamic wave detection module, an industrial control module, a hydraulic compensation control module (5), a lifting/lowering compensation apparatus, and an ore-raising pipe (12). The hydraulic compensation control module (5) is capable of implementing active compensation and passive compensation and selecting different compensation schemes on the basis of different sea conditions. With the two compensation schemes being designed independently and integrated in a same hydraulic system, two hydraulic compensation systems can operate independently without mutual interference, thus effectively suppressing vertical vibrations of the ore-raising pipe (12), and reducing the vibrational amplitude of transverse vibrations.
