Problems solved by technology

[0002] At present, there are mainly the following problems in the use of wave energy generation devices: the safety and reliability and the wave energy conversion rate cannot be balanced, the construction cost is high, and the terrain or sea conditions are restricted, and the scale cannot be well realized. application
Its disadvantages are: the wave energy generating device is equipped with an automatic control system, which makes the device too complicated, has poor reliability, and is difficult to realize practical application, and the automatic control system itself also consumes energy.
This requires the wave energy generation device to take into account the stable and efficient wave energy conversion rate and the reliability of the structure. At the current stage when the wave energy technology is not yet mature, the reliability is very important. If necessary, the efficiency can be lower, but it still needs to be higher high reliability
