The invention discloses a cable-shaped ocean energy collecting device and an energy collecting method thereof.The energy collecting device is a mooring cable and comprises an outer ring and an inner ring, the outer ring is attached to and wraps the inner ring, the outer ring is of a steel wire structure, each strand is formed by equidistant twisting and conventional right twisting, the outer layer of the inner ring is made of waterproof materials, piezoelectric crystal PVDF piezoelectric patches are attached to the inner layer according to an array, and the piezoelectric crystal PVDF piezoelectric patches are attached to the outer layer of the mooring cable. Sea waves are transmitted from different directions, the piezoelectric mooring rope can receive wave energy from all directions, the mooring rope deforms due to the wave energy, so that the piezoelectric plate on the inner ring is extruded and bent to generate electric polarization, and energy conversion from sea wave energy to mechanical energy and from the mechanical energy to electric energy is achieved. The device not only converts and reduces the external force borne by the mooring rope, but also converts the external force into electric energy to be used by an offshore platform. The device is energy supply equipment which can be used on a large scale at any time and any place.

    本发明公开一种缆状海洋能量收集装置及其能量收集方法,该能量收集装置为系泊缆,包括外圈和内圈,外圈贴合包裹内圈,其中外圈为钢丝结构,每一股均为等距捻和常规右捻,内圈外层由防水性材料制成,内层按阵列贴上压电晶体PVDF压电片,海上的波浪是从不同方向传来的,而此压电系泊缆可以接收来自各方向上面的波浪能,缆绳因波浪能而产生形变从而致使内圈的压电片受到挤压弯曲发生电极化,从而实现海浪能到机械能,机械能到电能的能量转化。该装置不仅仅转化减小了系泊缆所受到的外力,还将此外力转换为电能供海上平台使用。是一种可以实现大规模、随时、随地使用的供能设备。
