Abstract
Disclosed is a wind power generating unit with cylindrical air drums. Single blades rotating along with an axis inside two cylindrical drums and a sector choke valve rotating reversely are utilized togenerate a circulating conversion wind-power action to rotate and drive an electric generator to work. The wind power generating unit with cylindrical air drums can be mounted on the ground of an airport, utilizes a form of concentrating wind power via a bell-shaped cavity, and can generate pressure of equal stressed areas of blades to drive the electric generator to work normally even when thewind power of the electric generator utilizing a press plate and a choke valve to convert wind power is low.
Description
Technical field
The utility model relates to a kind of circle air duct wind generating unit, especially adopt the automatic conversion of single blades and covering of the fan choke valve, make this pressure plate wind stopping valve conversion wind power generator under the very low situation of air quantity, produce identical Driving force and drive generator work with the single blades lifting surface area.
Background technique
At present, known wind generating unit is made up of pole, fan blade, guide plate, generator.Because fan blade needs to bring up to enough height with pole, for considering the strength of wind generating unit pole when the strong wind, the fan blade common design becomes narrow stressed dignity, therefore at air quantity hour, fan blade can't drive generator operation, and wind-driven generator remains static when causing little air quantity.
Summary of the invention
In order to overcome the deficiency that existing wind-driven generator can't proper functioning when the low air quantity, the utility model provides a kind of circle air duct wind generating unit, this device can not only make generator operation work when little air quantity, and can be set on the ground, air port, a large amount of air quantity is gathered in intake grill, and the output rotatory force offers generator work to make it produce greatly.
The technological scheme that its technical problem that solves the utility model adopts is: on the side face of two circle air ducts, offer 120 ° of circular arc openings, and offer two mouthfuls respectively on circular arc opening disc, as exhaust outlet and intake grill.A fan blade is installed on the axis of circle air duct, and the barrel side face of fan blade and circle air duct needs the rotation of sealing.A sprocket that the specification number of teeth is identical respectively is installed on the fan blade axis, the fan blade sprocket wheel of two circle air ducts is connected with the sprocket wheel of generator, do to rotate with speed in the same way with chain.At the aperture position of 120 ° of circular arcs of circle air duct, be slightly larger than the covering of the fan choke valve of circle air duct radius with a radius.The radian central angle that keeps out the wind of covering of the fan choke valve is that 280 ° of width are greater than the fan blade width in the circle air duct.The circumferential surface of covering of the fan choke valve need be pressed close to the axis limit of fan blade, and sealing can independent operation.The covering of the fan choke valve the axle on also install one with the identical sprocket wheel of the fan blade axis specification number of teeth, sprocket wheel is installed in the opposite direction of Transmitted chains, make covering of the fan choke and fan blade the work with fast backward rotation.The preceding line position that fan blade rotates is as exhaust outlet.Another of circle air duct mouthful as intake grill, and connected the intake grill of two circle air ducts.For ease of assembling the intake grill that more air quantity enters the circle air duct, intake grill is designed to the horn chamber shape.
The beneficial effects of the utility model are: can under the situation of low air quantity pressure plate wind stopping valve conversion wind power generator be run well, and generation and the corresponding Driving force of fan blade lifting surface area offer generator work.
