Piezoelectric wind direction wind speed measurement device

Abstract

The invention relates to a piezoelectric wind direction wind speed measurement device and belongs to the wind force measurement technical field. A photovoltaic cell sheet is arranged on the upper wallof a main body; a semi-shaft is arranged at the lower part of the lower wall of the main body; sensors, a circuit board and a shell are arranged at the upper part of the lower wall of the main body;the sensors are uniformly distributed on a circumference which adopts the axis of the semi-shaft as a center; the circuit board and the sensors are arranged in a cavity formed by the shell and the lower wall of the main body; the semi-shaft is mounted on a base through a bearing; two magnets are embedded in the base; the centers of the magnets are located on the same circumference with the centersof the sensors; the magnets are symmetrically arranged at two sides of the semi-shaft; sensing vibrators are installed on the shell; a partition board is installed between the front wall and back wall of the main body; energy harvesting vibrators are installed on the partition board; the sensing vibrators and the energy harvesting vibrators tilt towards the left side and right side of the main body respectively; flag sails are mounted at the external sides of the front wall and rear wall of the main body; the energy harvesting vibrators and the sensing vibrators are of pre-bent structures formed through bonding substrates and piezoelectric sheets together, the radius of the piezoelectric sheets being larger than the radius of the substrates; the substrates of the energy harvesting oscillators are adjacent to the partition board; and the piezoelectric sheets of the sensing vibrators are adjacent to the shell.
