Automatic-folding-type wind machine capable of resisting violent typhoon

The invention discloses an automatic-folding-type wind machine capable of resisting violent typhoon. Each wing machine blade comprises an upper blade portion and a lower blade portion, the upper bladeportion is hinged to the lower blade portion through a hinge device, and a motor transmission system is installed in the lower blade portion, is in transmission connection with the hinge device and can drive the upper blade portion to rotate opposite to the lower blade portion through the hinge device, so that the wing machine blade is bent; when the upper blade portion rotates to the stroke endpoint of the upper blade portion, a tip of the upper blade portion right abuts against the upper end of a lower blade portion of one adjacent wing machine blade, and a hoist is arranged in the upper portion of the lower blade portion of the wing machine blade and provided with a stay rope; one end of the stay rope winds the hoist, the other end of the stay rope is fixedly connected with an adjacent upper blade portion, the
