The invention relates to a self-powered anemoscope, belonging to the technical field of
wind power measurement. a semi-shaft and sensors are arranged above the swing disc body, a boss, a circular table, and a circuit board are arranged under the disc body, the sensors are uniformly distributed on the circumference by taking the center of the semi-shaft as the circle center, a sail support sleeve with canvas sleeves the semi-shaft, the sail support
chassis is pressed on the swing disc body through a group of rollers, two magnets symmetrically arranged at the two sides of the semi-shaft are embedded under the sail support
chassis, an outer casing is arranged on a base, an
exciter connection board is arranged on the boss of the base, the
exciter connection board is provided with a swing rod, an excitation disc is arranged on the swing rod, a stud is arranged on the excitation disc, the stud is connected with the boss of the swing disc, the side wall of the boss of the base is uniformly provided with generating units each consisting of a flat spring and piezoelectric oscillators symmetrically arranged at the two sides of the flat spring, the free end of the flat spring and the edge of the excitation disc contact and don't act with each other, each piezoelectric oscillator is formed by the bonding of a substrate and a piezoelectric sheet, the free end of the substrate is provided with a
flange, and the substrate is close to the flat spring and the
flange abuts against the flat spring.
