The invention discloses a wave compensation device for a mining ship. The wave compensation device comprises a collecting mechanism, a control mechanism connected with the collecting mechanism and a hydraulic mechanism connected with the control mechanism. The acquisition mechanism comprises a displacement sensor arranged on the mining ship and a wave motion acquisition unit connected with the mining ship; the hydraulic mechanism comprises a combined type hydraulic cylinder, a main control valve, an oil pump and a prefill valve, wherein the main control valve and the oil pump are connected with the combined type hydraulic cylinder, and the prefill valve is connected with the main control valve in parallel. Through the displacement sensor or the wave motion acquisition unit, the displacement of the mining ship is detected in real time or the motion trail of the mining ship is predicted, active and passive composite wave compensation is achieved, the heaving motion of the marine mining ship is reduced, and therefore it can be guaranteed that the mining ship can stably operate under the irregular influence of sea waves, and the compensation precision is improved.
本发明公开了一种采矿船波浪补偿装置,包括:采集机构,与采集机构连接的控制机构,以及与控制机构连接的液压机构;采集包括机构:设置在采矿船上的位移传感器,与采矿船连接的波浪运动采集单元;液压机构包括:复合式液压缸,与复合式液压缸连接的主控制阀和油泵,以及与主控制阀并联的充液阀。通过位移传感器或波浪运动采集单元,实时检测采矿船位移量或预测采矿船运动轨迹,实现主被动复合型波浪补偿,减少海洋采矿船的升沉运动,从而让可以保证采矿船在海浪的无规律影响下也可以稳定运行,提高了补偿的精度。
