Abstract
The utility model relates to a wind power generator with a vertical axle, a rotary wind wheel and upper and lower pressurizing covers and swinging wind blades. Each wind blade on the wind wheel is made into a swinging type, and the upper and the lower parts of the wind wheel are respectively provided with a pressurizing cover. When the wind wheel is blown by wind, the side of the dynamic surface of the wind wheel closes the wind blades by the function of wind force to prevent the wind from passing through and only the dynamic surface of the wind wheel can be pushed to rotate the wind wheel. The side of the resistance surface of the wind wheel opens all the wind blades by the function of the wind force, and the wind passes through from each wind blade. The resistance of the resistance surface of the wind wheel is reduced, and the resistance of the resistance surface is nearly zero. Thus, the speed of the wind wheel is increased, the torque force of the wind wheel is increased and the power generating efficiency is increased. Under the condition that the wind wheel is the same, more electric energy can be generated.
Description
Affiliated technical field
The utility model relates to a kind of wind generating unit.
Background technique
Wind generating technology is applied in many countries in the world at present, and wind-power electricity generation is the green energy, and wind is inexhaustible.China's wind-power electricity generation generally is horizontal shaft type and vertical shaft type wind power generation device.The vertical shaft type wind power generation device generally is made up of generator, vertical shaft and wind wheel, and very little to wind wheel when wind, the strength of the fan blade wind-engaging on the wind wheel drives wind wheel and horizontally rotates, and wind wheel drives vertical shaft and generator rotation and generates electricity.Though existing perpendicular axis type wind-wheel generating device not wind-engaging to influence and rotate, fan blade angle on the wind wheel and shape directly influence the rotational speed of wind wheel, generally all fan blade are made convex-concave.Concave surface goes for a drive, and produces rotating power, makes the direction rotation of wind wheel to the fan blade projection.General wind blows from side's substantially horizontal, so the fan blade concave surface is subjected to wind to produce rotating power, the fan blade convex surface is subjected to wind to produce rotational resistance, and only dynamic during greater than resistance, wind wheel could rotate.Because cancelling out each other, power and resistance wasted a part of wind-force like this.Fail to make full use of wind resource.
Summary of the invention
Suffered resistance when existing technology fails fully to overcome the wind wheel rotation, the wind wheel Power of Spin is little, and speed is slow, and generating efficiency is low, fails to make full use of wind energy.The utility model provides a kind of can reduce rotational resistance greatly, and wind wheel is speeded up, and torsion strengthens, and improves the electricity generating device of generating efficiency.
The technical solution adopted in the utility model is: the electricity generating device of being made up of generator, vertical shaft and wind wheel, for making wind wheel rotation the time reducing resistance, improve rotating speed, wind wheel is improved, it is characterized in that: the fan blade on the wind wheel is made swing type, and wind wheel has upper and lower supercharging lid respectively, upper and lower supercharging lid symmetry, make three semicircles respectively and join and connect again on the vertical shaft, between the upper and lower supercharging lid with three main pillars with several minutes pillar be connected.Three main pillars are connected to supercharging up and down and cover on the semicircular center of circle, divide pillar to be connected to supercharging up and down and cover on the semicircular circular arc, connect a branch pillar every a segment distance on circular arc.Each divides on pillar and adorns a fan blade, divides pillar hinged with a side of fan blade, and the hinged opposite side of fan blade is towards the center of circle of semicircle during installation, and fan blade can be swung on minute pillar, and the branch pillar also plays the effect of blocking fan blade.When wind blows to wind wheel by the direction of arrow, a side of wind wheel, under the effect of wind-force, fan blade is all closed and is branched post and blocks, and forms the wind wheel power face, and wind can not be passed through, and can only promote these wind wheel power face of tieing up with a lot of fan blades wind wheel is rotated; The opposite side of wind wheel is under wind action, and fan blade is come the effect of direction power by wind, and fan blade swing open, wind form the wind wheel resistance area between each fan blade, have reduced the resistance of resistance area so greatly, and the resistance of resistance area is almost nil.Fan blade along with the shape of circular arc, is closed fan blade and is blocked wind when the wind wheel power face, forms spill, add the effect of upper and lower supercharging lid, in spill, produced powerful blast and made wind increases, wind wheel is speeded up, torsion strengthens, and wind wheel is by the direction rotation of curved arrow.This wind wheel power face and wind wheel resistance area are three, also can be provided with wind wheel power face and wind wheel resistance area more than two, reach the wind comes from of different direction and can both make the wind wheel rotation.The position of fan blade and branch pillar is provided with vibration damping equipment, the vibration and the noise that produce in the time of can reducing the fan blade swing.
The beneficial effects of the utility model are, on the branch pillar of wind wheel, installation can be swung fan blade, make power face increase Driving force greatly, resistance area has reduced resistance greatly, has increased the speed of wind wheel rotation, strengthened the torsion of wind wheel, can both make the wind wheel rotation to the wind comes from of different direction, improve generating efficiency, under onesize wind wheel situation, can send more electric energy.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a plan view of the present utility model.
Among the figure 1, vertical shaft, 2, go up the supercharging lid, 3, supercharging lid down, 4, main pillar, 5, divide pillar, 6, fan blade, 7, generator, 8, the wind wheel power face, 9, the wind wheel resistance area.The direction of arrow in the accompanying drawing is wind direction, and the curved arrow direction is the wind wheel sense of rotation.
