A floating wind speed monitor based on nanogenerator

Abstract

The invention discloses a floating wind speed monitor based on a nano-generator, which specifically comprises an upper unit, a middle unit and a lower unit which are connected in sequence. The middle unit is provided with a rectifier circuit. The lower unit contains piezoelectric nanogenerators for generating electricity. The upper unit includes a plurality of air vibrating membranes whose center and the center of gravity of the upper unit are located on the same horizontal plane, and the planes where any two adjacent air vibrating membrane structures are located are perpendicular to each other and are located on different planes of the upper unit. The upper unit also includes a plurality of triboelectric nanogenerators operating in independent layer mode parallel to the plane of the air vibrating membrane, and the plurality of triboelectric nanogenerators together constitute a wind speed sensor for wind speed monitoring. The invention can monitor ocean surface wind speed data through a floating self-powered wind speed monitor, and combined with the ocean surface wind speed data can reduce the error of satellite remote sensing ocean surface wind field data, and has positive significance for practical application.

Description

technical field [0001] The invention belongs to the field of marine environment monitoring, in particular to a floating wind speed monitor based on a nanogenerator Background technique [0002] Anemometer is a kind of marine environment monitoring equipment, which is widely used in marine meteorological monitoring of ports and coasts. Conventional anemometers are mainly divided into two types: mechanical and ultrasonic. The mechanical method relies on the rotation of the wind cup to measure the wind speed. The structure is simple and the price is low, but it is easy to lose and the measurement results are not accurate enough. The ultrasonic type uses the ultrasonic time difference method to measure the wind speed and direction, but it is easily affected by the environment and climate. In addition, the traditional anemometer equipment is large and can only be installed and fixed in one place, requiring an external power supply to supply energy, and it is difficult to effect...
