VERTICAL ROTATION SHAFT ROTARY WINDMILL Russian patent published in 2005 - IPC

FIELD: wind power engineering.

SUBSTANCE: proposed rotary windmill with vertical rotation shaft consists of support truss having at least three supports, upper and lower crossmembers connecting supports to form rigid structural unit, upper and lower support platform with holes in center and connected to cross members. Upper and lower bearing housings are secured on upper and lower support platform coaxially with holes which accommodate upper and lower bearings installed, respectively, on upper and lower ends of shaft of rotor arranged inside support truss between support platforms for rotation. Windmill is provided with working members in form of blades. Blades are made as part of hollow sphere or hollow cylinder. Support of truss are rigidly secured on base frame. Invention is aimed by increasing efficiency and improving serviceability of rotary windmill owing to provision of rigid truss, failless service life owing to reduction of vibration of structure at use of rigid truss, increasing power of rotary windmill with vertical shaft of rotation owing to increased sizes of rotor both in diameter and height using rigid truss.

EFFECT: increased efficiency, power output and service life.
