Title:
WIND SPEED ACCELERATION TYPE WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2023/095359
Kind Code:
A1
Abstract:
[Problem] To provide a wind speed acceleration type wind turbine in which a wind speed on a dorsal surface of the wind turbine is increased and a wind speed in an outlet part of a wind tunnel body is increased, thereby increasing the rotational efficiency of a blade and improving a problem relating to the height of the device and improving the stability of the device and the stability of a wind tunnel body support. [Solution] Provided is a wind speed acceleration type wind turbine comprising a wind tunnel body 22 and a wind turbine 21, wherein: the wind tunnel body 22 comprises a front wind tunnel member 22-1 which has a substantially rectangular cross section, and which is formed such that a cross-sectional area thereof contracts linearly or curvilinearly from a wind inflow port 22a, and a rear wind tunnel member 22-2 formed so as to enlarge linearly or curvilinearly from the position of the contracted cross-sectional area to a wind outflow port 22b, or so as to maintain the same cross-sectional area; and the wind turbine 21 effects wind speed acceleration in a two-stage manner by increasing the speed of a high-speed airflow blowing through space portions S on both sides and increasing the speed of a low-speed, high-pressure airflow that has been diffused by the rear wind tunnel member 22-2, by means of friction with a high-speed airflow outside the wind tunnel body 22.
