Description
[technical field] [0001] The invention relates to the technical field of ocean environment wave energy collection, in particular to a non-contact transmission friction-electromagnetic composite wave energy collector adaptable to complex excitations. [Background technique] [0002] In recent years, with the acceleration of the industrialization process in various countries, energy consumption has continued to increase, and the development of renewable energy has become the core content of many countries' promotion of energy transformation. Ocean energy is an inexhaustible, non-polluting, renewable energy, and one of the most abundant, clean, and renewable energy sources on earth. The wave energy in marine energy has the incomparable advantages of other energy sources, and its dependence on season, day and night, weather and temperature conditions is greatly reduced. Therefore, rational development and utilization of wave energy has great strategic significance. [0003] The...
