Definitions
- the present invention relates to a propeller that maximizes power generation efficiency during light winds and prevents damage to a wind power generator during strong winds.
- the present invention aims to maintain the maximum power generation efficiency and prevent breakage due to strong winds by adjusting the wing angle according to the strength of the wind. Disclosure of the invention
- Figure 1 is a side view showing the propeller turning when the propeller angle adjustment hydraulic cylinder rod is retracted and wind is blown to the propeller.
- Figure 2 is a side view showing the propeller folded with the propeller angle adjustment hydraulic cylinder rod extended.
- Fig. 3 is a side view showing code diagrams of each part.

Abstract
Par les forces d'un vent ordinaire, d'un typhon et d'une rafale, une pompe à huile hydraulique est amenée en rotation pour créer une pression dans un clapet de commande, de sorte qu'un générateur est amené en rotation pour générer de l'électricité grâce à l'énergie éolienne par l'intermédiaire d'un cylindre hydraulique présentant une hélice pliante, un cylindre hydraulique destiné à élargir l'hélice, un arbre d'hélice, un montant d'arbre d'hélice, un palier, un support de réglage d'angle de montant d'arbre d'hélice, et un arbre de support de réglage d'angle de montant d'arbre d'hélice.
