Abstract
The utility model relates to a plate drum wind wheel wind generator with a swinging wind plate, which is designed to solve the defects of low efficiency and low utilization ratio of wind energy existing in the existing plate drum wind wheel wind generators. The wind plate of a plate drum wind wheel is composed of a fixed wind plate and a swinging wind plate which are in flexible connection, and the swinging wind plate is externally extended in a power surface of the plate drum wind wheel to enlarge the wind acceptance area and the torque so as to add effective power; the swinging wind plate is retracted in a resistance surface of the plate drum wind wheel so as to reduce the wind acceptance area and the torque; simultaneously, the resistance surface of the plate drum wind wheel is provided with a wind screen which is controlled by a wind vane, which effectively adds the power of the plate drum wind wheel. The utility model can be used for wind power generating systems and various wind machines.
Description
The utility model belongs to a kind of wind plate swinging type plate tube wind-wheel wind power generation machine that wind power generation field is used.
Existing plate cartridge type wind-wheel wind power generation machine is made up of generator, main shaft and plate cartridge type wind wheel, the axle of plate cartridge type wind wheel is vertically disposed, the axle of wind wheel is provided with the aerofoil of some planars or bent plate shape, the wind blows aerofoil, wind wheel is horizontally rotated, drive generator by main shaft and send electric power.Its principle is, wind wheel makes the wind wheel main shaft rotate in the face of wind direction after the effect of wind-engaging power, and the one side that drives generator for electricity generation is a power face; Another side is a resistance area then, and wind wheel has been rotated inhibition.The aerofoil that designs according to fluid motion principle and characteristics when the steering power face, by the concave curved surface of bent plate shape aerofoil or the interior inclined-plane angle of planar aerofoil, has all absorbed the energy of suffered wind-force basically, forms power; When steering drag face, by the convex surface or the outer inclined-plane of aerofoil, disperseed the energy of suffered wind-force, the power that the resistance that resistance area is produced produces less than power face.The difference of the two becomes the promotion wind wheel and main shaft rotates and the effective power of drive generator for electricity generation.Because the structural feature of plate cartridge type wind wheel requires the numerical value of startup wind-force higher, the differential force of wind wheel power face and resistance area is less, and the difficulty that improves effective power is bigger, so also undesirable to the utilization ratio of wind resource.
The utility model is a kind of effective power that improves plate cartridge type wind wheel that designs at the deficiencies in the prior art, increases substantially the wind plate swinging type plate tube wind-wheel wind power generation machine of generating efficiency.
The utility model is realized by following measure.Mainly be made up of plate cartridge type wind wheel, main shaft and generator, it is characterized in that: every pectinid plate of plate cartridge type wind wheel is made up of stationary airfoil and swing aerofoil two-part of being fixed on the central shaft; Stationary airfoil is that curved surface is tabular, and the swing aerofoil is a plane tabular; The swing aerofoil flexibly connects by folding shape movable axis device and stationary airfoil; Joint at swing aerofoil and stationary airfoil is provided with limit stoper and vibration damping equipment; The quantity of swing aerofoil can also can all adopt the swing aerofoil more than the quantity of stationary airfoil, and the swing aerofoil of this moment can be separately and the flexible connection of the support on the axle.In facing the wind resistance area one side of direction of plate cartridge type wind wheel, be provided with height is slightly larger than the wind wheel external diameter a little more than height, the curvature of wind wheel curved surface barge board.The covering arc of barge board is equal to or less than 1/4th of wind wheel excircle.Barge board is connected with position adjusting mechanism, and said position adjusting mechanism is by artificial, mechanical and electronic control, or wind vane control is set on barge board.When electricity generating device was worked, the rotation of plate cartridge type wind wheel when aerofoil rotates to the position of wind wheel power face, was swung aerofoil abduction under the effect of wind-force, has increased the wind-receiving face and the moment of wind wheel, has absorbed the energy of wind-force, has increased the power of power face.When the swing aerofoil turned to the resistance area of wind wheel with stationary airfoil, swing inwards was limited on the position of minimum angles under the effect of wind-force, has blocked stationary airfoil simultaneously, has reduced the wind-receiving face and the moment of wind wheel, has reduced the resistance of wind wheel.Therefore, the effective power of wind wheel obviously increases.Limit stoper can limit the swing abduction of aerofoil and the position of interior receipts, vibration damping equipment can be less vibration and noise during the aerofoil swing.Barge board is in resistance area one side of wind wheel all the time under the synchronization control of position adjusting mechanism or wind vane, reduced the influence of wind-force to the wind wheel resistance area greatly.
The utility model has the advantages that, under the constant situation of the height of wind wheel and diameter, can obviously reduce the numerical value of minimum startup wind-force, reduce the resistance that the wind wheel resistance area produces effectively, increase the effective power of wind wheel acting, improved the generating efficiency of complete machine significantly.The barge board technology can be applicable on various plate cartridge type wind wheels and each population cone wind wheel.
Accompanying drawing 1 is the working position schematic top plan view of the utility model plate cartridge type wind wheel, and (1) is axle among the figure; (2) be stationary airfoil; (3) be the swing aerofoil; (4) be movable axis; Maximum gabarit when (5) being the rotation of plate cartridge type wind wheel.Accompanying drawing 2 is a barge board schematic representation of the present utility model, and (6) are barge board among the figure; (7) locate resistance area into wind wheel; (8) locate power face into wind wheel.The direction of arrow in the accompanying drawing is wind direction, and curved arrow is the direction of wind wheel rotation.
An embodiment of the present utility model is, electricity generating device is made up of generator, main shaft and plate cartridge type wind wheel, and the stationary airfoil (2) of plate cartridge type wind wheel is installed in vertically disposed axle (1) and goes up, swings aerofoil (3) by movable axis (4) and stationary airfoil (2) flexible connection.Joint at swing aerofoil and stationary airfoil is provided with limit stoper and vibration damping equipment.Limit stoper is made up of fixed stop, in order to limit the limit position of swing aerofoil; Vibration damping equipment is made up of pressure spring.In facing the wind resistance area (7) one sides of direction of plate cartridge type wind wheel, be provided with barge board (6), barge board is the center rotation with the main shaft, by the position of superincumbent wind vane box haul control barge board is set.
