ROLLER TYPE SOLID-LIQUID CONTACT WIND SPEED SENSOR BASED ON FRICTION NANO-GENERATOR

A triboelectric nanogenerator-based roller-type solid-liquid contact wind speed sensor, comprising: a rotating shaft (3) that integrally has a centrally hollow structure; a cover (4) that integrally has a circular structure; lower magnetic blocks (501) that are fixedly mounted at opening positions on the outer side of a housing body (5); limiting holes (502) that are formed at symmetrical positions of inner walls of the opening positions on the outer side of the housing body (5); wind cups (6) that are detachably mounted on the outer side of the housing body (5); a first metal layer (7) that is fixedly electroplated on the inner wall surface of the housing body (5); a second metal layer (8) that is correspondingly electroplated below the first metal layer (7), and the first metal layer (7) and the second metal layer (8) both having a semicircular structure but not being in contact with each other; dielectric layers (9) that are uniformly arranged on the outer surfaces of the first metal layer (7) and the second metal layer (8); and deionized water (10) filled inside the housing body (5). According to the triboelectric nanogenerator-based roller-type solid-liquid contact wind speed sensor, a novel structural design is adopted, such that pulse currents generated by a triboelectric nanogenerator are all forward, and thus direct currents are output and do not need to be converted again; moreover, the size can be flexibly designed according to requirements, such that a device can be widely applied in the field of ship engineering and the field of marine meteorology.
