The automatic compensation device comprises a tidal range compensation hydraulic cylinder, a guide groove, a travel switch and a tidal range hydraulic transmission system.

Description

Technical field: [0001] The invention relates to an automatic tidal range compensation system and a control method for a wave energy generating device. Background technique: [0002] In the face of increasingly severe climate issues and energy crises, the development of clean and renewable energy has become a global consensus. Ocean renewable energy with huge energy has received extensive attention; wave energy is a specific form of ocean energy and one of the most important energy sources in ocean energy. Its development and utilization are of great importance to alleviate the energy crisis and reduce environmental pollution. very important. The movement of rough sea waves produces huge, eternal and environmentally friendly energy. If the kinetic energy of sea waves and the wave energy of other water surfaces can be fully utilized, the prospect of world energy will be quite broad and bright. [0003] Wave energy is a clean and reliable renewable energy. The wave energy po...

Problems solved by technology

However, the sea tidal range changes greatly, which greatly affects the power generation efficiency and reliability of the wave energy generation device. When the tide level rises and the wave energy generation device does not change with the tide level, the power generation hydraulic cylinder piston may appear under large wave conditions. The relative movement stroke of the cylinder is too large to cause damage to the hydraulic cylinder; and the existing solution is to compensate the tidal range through mechanical means. The changeable marine environment has a great impact and low reliability, which is not conducive to improving the power generation efficiency of wave energy power generation devices
