A self-powered wind direction and wind speed monitor

Abstract

The invention relates to a self-powered wind direction and wind speed monitor and belongs to the wind power measurement field. A main body is provided with an end cover, flag sails and a semi-shaft; the main shaft of an exciter is mounted on the end cover and the bottom wall of the main body through a bearing; the left end of the main shaft is equipped with blades; the excitation plate of the exciter is provided with inner magnets and outer magnets; the size and number of the inner magnets are identical with the size and number of the outer magnets respectively; the inner magnets and the outermagnets are uniformly distributed at two circumferences with different radiuses; power generating units composed of leaf springs, piezoelectric oscillators, inertia blocks and excited magnets are uniformly arranged on the end cover; the substrates of the piezoelectric oscillators are adjacent to the leaf springs; the folded edges of the substrates abut against the leaf springs; the magnetic polesof the excited magnets, the inner magnets and outer magnets, which have different magnetism, are opposite to each other; before being mounted, the piezoelectric oscillators are of flat and straight structures; after being mounted, the piezoelectric oscillators are of bent structures; the bottom wall of a shell sleeves the semi-shaft; the side wall of the shell is installed on the side wall of themain body; the inner side of the bottom wall of the shell is provided with a circuit board; sensors are uniformly arranged on the outer side the bottom wall of the shell; the semi-shaft is installedon a base through a bearing; two round magnets are embedded in the base; the centers of the round magnets and the centers of the sensors are located on the same circumference; and the round magnets are symmetrically installed at two sides of the semi-shaft.

Description

technical field [0001] The invention belongs to the technical field of wind force measurement, and in particular relates to a self-powered wind direction and wind speed monitor. 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. Contents of the invention [0003] The present invention proposes a s...
