Title:
WIND SPEED MEASUREMENT APPARATUS HAVING WIND GUIDE PATH
Document Type and Number:
WIPO Patent Application WO/2013/105758
Kind Code:
A1
Abstract:
The present invention relates to a structure capable of measuring the strength of wind by inducing the wind coming from eight directions, wherein the strength of pure wind can be measured through a passage structure for transmitting the wind only to inner surfaces of bent wings of a turbine by forming a plurality of half-moon-shaped through-holes bent in an S curve at a predetermined angle, on a lateral surface of a body having a predetermined shape which comes in contact with the outside, to naturally induce the gentle wind having a predetermined strength to a central part of the body by reducing a predetermined diameter thereof, and to apply the wind to the bent internal sections of the turbine. As a result, a rotator is exposed to remove the influences derived from elements except for the wind, and the wind coming from one direction is naturally ventilated and discharged in the opposite direction by inducting only the wind to a wind guide path so as to measure only the strength of pure wind. The existing apparatus measures the occurrence of a voltage connected to the rotator or a rotational shaft using the rotation of the turbine by exposing the turbine to the outside for acquiring the rotational force through the wind and has many limitations such as the freezing of the rotator due to various external elements or the short life-cycle of the apparatus according to water penetration, and the like. The apparatus of the present invention can overcome the above limitations, and can be utilized as an independent wind speed sensor attachable to a module having a predetermined volume so as to provide a measurement of a reliable value (wind speed) by protecting the internal pinwheel under extreme conditions such as high altitude.
