Self-protection system and method of wave-energy generating set in extreme marine environment

Abstract

The invention discloses a self-protection system and method for a wave-energy generating set in an extreme marine environment. The self-protection system comprises two cylindrical rigid guide columns,wherein the bottoms of the two cylindrical rigid guide columns are buried deep in a seabed, and the tops of the two cylindrical rigid guide columns are exposed out of the sea surface. Working platform lifting devices are mounted at the tops of the guide columns, and a working platform is mounted at the top ends of the working platform lifting devices. A controller, a single-chip microcomputer, anelectromagnetic relay and a storage battery are mounted in the working platform. A vibration-absorption block lifting device is mounted at the top of the working platform. A vibration-absorption block is mounted at the top of the vibration-absorption block lifting device. According to the self-protection system and method, severe vibration of a floater and the working platform under an extreme sea condition is transferred to the vibration-absorption block fixedly connected with the working platform based on the power vibration-absorption principle, so that wave force directly borne by the working platform and the floater is exactly balanced by the acting force applied to the working platform and the floater by the vibration-absorption block, that is, severe vibration of the floater and the working platform is reduced by means of vibration energy absorbed by the vibration-absorption block from the floater and the working platform.

technical field [0001] The invention belongs to the field of wave energy generating devices, and in particular relates to a self-protection system and a self-protecting method of a wave energy generating device in an extreme marine environment in the field. Background technique [0002] In the case of extremely bad sea conditions, the float and working platform of the near-shore oscillating float wave power generation device will be impacted by huge wind and waves, which may damage the float structure and cause instability of the working platform due to excessive amplitude And overturning, which will seriously affect the life and working performance of the wave energy generating device. Therefore, it is necessary for the wave energy generating device to judge its own vibration in time when facing extremely severe sea conditions, and automatically and effectively take self-protection measures.

Problems solved by technology

[0002] In the case of extremely bad sea conditions, the float and working platform of the near-shore oscillating float wave power generation device will be impacted by huge wind and waves, which may damage the float structure and cause instability of the working platform due to excessive amplitude and overturning, which will seriously affect the life and working performance of the wave energy generation device

Therefore, it is necessary for the wave energy generating device to judge its own vibration in time when facing extremely severe sea conditions, and automatically and effectively take self-protection measures. However, most of the existing wave energy generating devices do not have self-protection functions. When sea conditions occur, some electrical equipment on the working platform of the wave energy generation device and the buoy itself will often be destroyed due to lack of timely protection
