Abstract
An automatic adjustment device for adjusting inclination of blades of wind turbines includes a first housing having multiple blades connected thereto and each blade has a first connection portion which is inserted into the firs housing. A transmission unit is connected to the first housing. A pump unit and a speed-changing member are mechanically connected to the transmission unit. The pump unit is mechanically connected to the speed-changing member. The pump unit has a driving unit which is connected with a transmission disk which is connected to the connection portions of the blades. The pump unit is activated by speed difference between the speed-changing member and the transmission unit so as to rotate the transmission disk via the driving unit, and adjust the inclination angle of the blades to protect the blades and increase the efficiency of the wind turbine.
