Abstract
A wind mill relates to an electric production facility which is a device converts wind power to kinetic energy, employing a vertical shaft and being uprightly arranged blades to correspond the wind direction without adjusting the orientation of the wind mill. A blade wheel which is equipped with two wheel arms and a wheel rim is arranged on a heavy shaft, wherein all the blades which encircle the blade wheel are uprightly arranged on the wheel rim with equal appearing intervals. Lashing wires are arranged near the edge of the blades in order to decrease the vibrating of the blades, and a girdle carrier which is connected with blades by a trestle is arranged on the bottom of the blades to prevent the wind mill being out of balance caused by falling of some blades. The structure forms multi-points supporting to blades, and lashing wires also reduce the vibrating of blades, thereby lowering the requirement of the blade material required by large-scale wind mill, largely increasing the serving life of the wind mill, and cutting down the manufacturing cost. Wind can enter into the sprue among blades, thereby making the wind mill act either on the windward side or on the leeward side, and eliminating the defect that blades of the leeward side of other vertical shaft wind mills increase the drag force of the wind mill.

Adopt vertical shaft and erect blade is installed, thus need not adjust wind energy conversion system towards come should and wind direction.Two impellers of being made up of spoke and wheel rim are housed on the macro-axis, all one weeks of blade ring impeller erect and equidistantly are installed on the wheel rim, in order to reduce blade vibration, lacing wire is equipped with at the place of keeping to the side on the blade, and the endless belt pallet is housed in the bottom of blade, prevent that some blade tenesmus from making the wind energy conversion system disequilibrium, by support blade is connected with pallet, this structure has formed multi-point support to blade, lacing wire has also reduced the vibrations of blade, the life-span of wind energy conversion system is increased greatly, reduced large scale wind power machine, reduced the manufacture cost of large scale wind power machine making the requirement of blade material.Because wind can enter the runner between the blade for twice, all can do work at windward side and leeward side, eliminated the defective of other upright shaft wind motor leeward side blades increase wind energy conversion system resistances.
Beneficial effect:
Owing to adopted vertical shaft and erect-type installation blade, so need not adjust blower fan towards come should and wind direction, this blower fan is connected blade on the main shaft by two impellers of being made up of spoke and wheel rim, the endless belt pallet is arranged at the bottom, guaranteed the smooth rotation of blade, there is the blade supporting frame to increase the strong point of blade again, formed multi-point support, the vibration that lacing wire on the blade has also effectively reduced blade edge makes the big increase in working life of blade and wind energy conversion system, has also reduced large scale wind power machine simultaneously to making the requirement of blade material.Because the runner that wind can enter for twice between the blade makes wind all can do work at windward side and leeward side, increased the efficient of wind energy conversion system.
