The invention relates to the field of ocean structure vibration control, in particular to a variable-liquid continuous-frequency-modulation ocean structure three-dimensional vibration control device which comprises a shell, the shell is cylindrical, an opening of the shell faces downwards, a first-stage balance vibration reduction mechanism is further arranged in the shell and comprises a large mass block, and a second-stage balance vibration reduction mechanism is further arranged in the shell. And the four groups of first damping rods are arranged on the peripheral wall of the large mass block. The large mass block of the device can be subjected to self-weight adjustment by pumping and draining seawater, continuous frequency modulation is achieved to adapt to different load conditions, the device can move in any direction in a three-dimensional space, balance and vibration reduction are carried out on swing and displacement of a floating type ocean structure including offshore wind turbine equipment, and the service life of the floating type ocean structure is prolonged. And moreover, through the intervention of an unlocking small mass block and a second damping rod, the working intensity of balance vibration reduction is further improved to cope with the weather of strong wind and strong waves, and the device effectively solves the problems that existing vibration control equipment is limited in direction and narrow in control frequency band.

    本发明涉及海洋结构振动控制领域,尤其是一种变液连续调频的海洋结构三维振动控制装置,包括外壳,所述外壳呈圆筒状设置,且所述外壳开口向下,所述外壳内还设置有一级平衡减振机构,其包括大质量块,以及设置于所述大质量块周壁上的四组第一阻尼杆。该装置的大质量块能够通过抽、排海水进行自重调节,做到连续调频以适应不同载荷条件,且能够在三维空间内进行任意方向上的运动,对漂浮式海洋结构包括海上风机设备的摆动和位移进行平衡和减振,且还可以通过解锁小质量块和第二阻尼杆介入,进一步提高平衡减振的工作强度以应对大风大浪天气,该装置有效地解决了现有振动控制设备存在方向限制和控制频带较窄的问题。
