Novel high-durability energy self-supply ocean monitoring buoy

The invention discloses a novel high-durability energy self-supply ocean monitoring buoy, which belongs to the technical field of buoys, and is characterized in that a wave energy capturing subsystem for converting wave motion into reciprocating rotary motion and an energy output subsystem for efficiently converting the reciprocating rotary motion into electric energy for output are arranged in a spherical shell; the rotor assembly comprises a plumb bob installed in the middle of a special-shaped shaft, a neodymium magnet and a TENG unit are symmetrically installed on the special-shaped shaft, a copper electrode is installed on the outer side of the TENG unit, and an acrylic circular ring is installed on one side of the copper electrode. The environment adaptability of the device is greatly improved, the durability of the device is greatly improved based on the solid-liquid contact electrification mode, and the novel ocean detection buoy can be put into use on a large scale, is low in cost and environmentally
