Abstract
The utility model discloses a kind of vertical-axis generators with flap valve blade, comprises the bearing, vertical shaft, the generator that connect successively from top to bottom, and wherein said bearing surrounding is consolidated with fixing rod, and vertical shaft is fixed with blade, and blade is flap valve blade; Flap valve blade comprises an external frame, is provided with multiple hollow-out unit lattice vent hole in external frame; Seal ring, seal ring is fixed on ventilated port surrounding; Hinge, hinge is fixed on vent hole top; Loose-leaf board, loose-leaf board and gemel connection are fixed.The utility model design is low for existing resistance-type vertical axis generator blade linear velocity, and the defect that generating efficiency is low, adopts and increase multiple flap valve structure on relative vane, and concave surface windward blades flap valve is closed, and concave-blade is formed as overall, produces effective push; Convex surface windward flap valve is open, and blade occurs multiple vent hole, convex surface resistance is reduced, and the vent hole on convex surface can also reduce resistance during rotation, thus linear velocity is increased, and increases wind energy utilization.
Description
Technical field
The utility model relates to a kind of vertical-axis generators with flap valve blade.
Background technique
Vertical axis aerogenerator comprises resistance type and lift-type.Shaft resistance type windmill, rely on windward side resistance and lee face resistance difference to obtain power, its difference is larger, and efficiency is higher.Existing resistance force type vertical shaft wind machine blade forms S shape relatively by two semicircle blade openings, but blade rotary surface friction drag exists, and make its linear velocity lower than wind speed all the time, fan efficiency is low.
Therefore a kind of object shaft resistance type windmill of effective increase fan efficiency is needed.
Summary of the invention
The utility model provides a kind of vertical-axis generators with flap valve blade for the defect of prior art, and its object is for effectively to increase fan efficiency.
The utility model is for realizing above object, adopt following scheme: a kind of vertical-axis generators with flap valve blade, comprise the bearing, vertical shaft, the generator that connect successively from top to bottom, wherein said bearing surrounding is consolidated with fixing rod, described vertical shaft is fixed with blade, and described blade is flap valve blade.
Preferably, described flap valve blade comprises an external frame, is provided with multiple hollow-out unit lattice vent hole in this external frame; Seal ring, sealing circle is fixed on ventilated port surrounding; Hinge, this hinge is fixed on vent hole top; Loose-leaf board, this loose-leaf board and gemel connection are fixed.
Preferably, described external frame is made up of two centrosymmetric bent frames; Described loose-leaf board and corresponding external frame are identical cambered surface, and its cambered surface is slightly larger than vent hole, and it is fixed on the contrary side of external frame arcuate directions.
The beneficial effects of the utility model: the utility model design is low for existing resistance-type vertical axis generator blade linear velocity, the defect that generating efficiency is low, adopt on relative blade, increase multiple flap valve structure, concave surface windward time blade on flap valve close, concave-blade is formed as overall, can produce effective push; Convex surface windward time flap valve open, blade occurs multiple vent hole, convex surface resistance is reduced, and the vent hole on convex surface can also reduce resistance during rotation, thus linear velocity is increased, increase wind energy utilization.
