Description

technical field [0001] The invention belongs to the technical field of wave energy power generation, and relates to a power generation device, in particular to a novel wave energy power generation device. Background technique [0002] Wave energy power generation is a power generation method that is getting more and more attention. Existing wave energy generating devices mainly include oscillating water column type, oscillating buoy type, raft type, surfing type, duck type, pendulum type and the like. But its shortcomings are as follows: [0003] (1) The safety is poor. The core mechanism of the device is exposed to the sea all the year round and is vulnerable to marine disastrous climate. Among them, the hydraulic transmission mechanism has the risk of oil leakage, is sensitive to temperature, and has poor working results; [0004] (2) The conversion efficiency is not high, and the three-stage energy conversion process of "machine-hydraulic-electricity" or "machine-gas-el...
