A pendulum-excited wind energy harvester

Abstract

The invention relates to a flag-swinging excitation wind energy gatherer, and belongs to the new energy field. The flag-swinging excitation wind energy gatherer is characterized in that a semiaxis and a sensor are arranged over the disk body of a swing disk; a boss is arranged at the center below the disk body, and a ring table is arranged at the outer rim of the disk body, and a circuit board is arranged below the disk body; a canvas frame sleeve sleeves the semiaxis, and can rotate around the semiaxis, and canvas is arranged on the sleeve; the center of two magnets which are symmetrically arranged below the base plate and the center of the sensor are arranged at the same circumference; a housing is arranged on a pedestal; a connection board of an exciter is arranged on the boss of the pedestal; a swing rod is arranged on the connection board; an excitation disk is arranged on the swing rod; a stud is arranged on the excitation disk; and the stud is in threaded connection with the boss of the swing disk; generation units are uniformly arranged on the side wall of the boss of the pedestal, wherein the free end of each bearing spring contacts the outer edge of the excitation disk, but has no interaction force; each piezoelectric vibrator is an arc structure which is formed through bonding of a substrate and a piezoelectric patch; the bending radius of the substrate is less than the bending radius of each piezoelectric patch; the substrate is arranged in a manner of approaching to the bearing spring; and the free end of the substrate presses against the bearing spring.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a pendulum-inspired wind energy collector, which is used for self-powered monitoring of wind direction changes in the environment. Background technique [0002] Wind direction and wind speed measurement technology has a wide range of application requirements in meteorology, civil aviation, highways and bridges, and mining industries. At present, new sensors, data acquisition and processing technologies for wind direction and speed measurement have made great progress, among which portable digital wind speed measuring instruments have been widely used in industrial production. However, there are still some key problems that need to be solved urgently in the field of wind direction and wind speed measurement, such as data acquisition, processing and energy supply for continuous remote transmission, low wind speed start-up of the measurement system, and so on.
