The invention belongs to the technical field of ocean energy power generation, and relates to an ocean wind power generation device. The device comprises a fixed pile, a rotary blade mounting pipe isarranged on the fixed pile, a lower rotating disc is fixedly arranged at the lower end of the rotary blade mounting pipe, and an upper rotating disc is fixedly arranged at the upper end of the rotaryblade mounting pipe. The fixed pile is provided with a generator, and an output shaft of the generator is in transmission connection with the upper rotating disc. A plurality of rotary blade assemblies are arranged on the outer wall of the rotary blade mounting pipe, each rotary blade assembly comprises a plurality of rotary blades, each rotary blade is provided with a rotary blade shaft, the outer wall of the rotary blade mounting pipe is provided with a plurality of guiding grooves, and the inner ends of the rotary blade shafts are movably arranged in the guiding grooves. The upper rotary blades are hinged to the upper rotating disc through upper hinges, every two adjacent rotary blades are hinged together through middle hinges, and driving mechanisms capable of driving the rotary bladesto move up and down under centrifugal forge generated due to rotation of the lower rotating disc are arranged between all the lower rotary blades and the lower rotating disc. The device has the advantage that the power generation device is prevented from being damaged by excessively large wind force in the ocean wind power generation process.
Description
technical field [0001] The invention belongs to the technical field of ocean energy power generation, and relates to an ocean wind power generation device. Background technique [0002] Wind power is the industry with the fastest development, the most mature technology and the broadest prospect in the renewable energy industry. my country has a vast territory and abundant wind energy resources, and my country has made renewable energy an important part of my country's energy strategy, so wind power has a huge potential market. However, when the wind-driven generator is in catastrophic weather such as natural disasters such as hurricanes, the wind-driven generator will cause the motor shaft to rotate too fast due to strong winds, thereby damaging the power generation equipment. Contents of the invention [0003] The purpose of the present invention is to solve the above problems in the existing technology, and propose a marine wind power generation device. The technical pr...
