As everyone knows, natural wind-force is not invariable, as everyone knows, natural wind-force is not invariable, make wind-driven generator obtain high efficiency, the seizure wind energy of blade is very crucial, but the blade of current wind-driven generator is all to adopt three, for simply thering is the tinsel of certain cambered surface, in the process of rotating, utilize the time of wind energy very short, and keep area windward also less, it is undesirable that the wind-driven generator of three blades catches wind energy, so also caused wind power generator efficiency unsatisfactory
Application number is 201020104231.4, invention and created name is the utility model patent of " double-head wind driven generator ", comprise vertical rod, fan, generator and storage battery, be characterized in: generator is arranged in vertical rod, fan has big fan and small fan, they are arranged on respectively the two ends, left and right of generator shaft, wind direction angle-adjusting mechanism is installed between big fan and generator, the top of generator is provided with vertical rod and sail, sail bottom has connecting rod to be connected with the mechanism that adjusts generator angle according to wind direction, and generator connects storage battery after guiding to change-over circuit by wire.When wind direction is for the wind time, generator shaft runs well, generating output energy; In the time that wind direction is contrary wind, make generator generator shaft can realize normal operation according to wind direction angle-adjusting mechanism, reverse and can not occur.This wind-driven generator structure is simple, and cost is low; Wind-force capturing ability is strong, and efficiency is high, safe and reliable, adapts to wide.But the blade of this wind-driven generator is simple three tinsels with certain cambered surface also, in the process of rotating, utilize the time of wind energy equally very short, keep area windward less, the seizure wind of blade is undesirable, has so also caused wind power generator efficiency unsatisfactory.
Two. summary of the invention
The object of the invention is to manufacture and design a kind of four leaf double-head wind driven generators, all to adopt three to overcome the blade of current wind-driven generator, for simply thering is the tinsel of certain cambered surface, in the process of rotating, utilize the time of wind energy very short, and keep area windward also less, the seizure wind energy of three blades is undesirable, has so also caused the unsatisfactory shortcoming of wind power generator efficiency.
The object of the present invention is achieved like this: a kind of four leaf double-head wind driven generators, mainly comprise generator 12, be separately fixed at big fan 1 and the small fan 11 of generator shaft 18 rear and front ends of generator 12, be arranged at the fixed window leaf 2 of generator 12 front ends and turn active window leaf 3, rear and front end respectively with the connecting rod 4 that turns active window leaf 3 and sail 5 and be connected, the sail 5 that is arranged at generator 12 tops and is connected with connecting rod 4, it is characterized by: there is blade fixed base 23, the bottom surface of described blade fixed base 23 is rectangle, near of the four edges of rectangle has the fixing tread 24 of blade of energy stator blade.
Blade fixed base 23 use metals can or plastics make.
Take the present invention of above measure, simple in structure, cost is lower, has adopted four blades, and stator blade is reliably not easy to become flexible, the blade that has overcome current wind-driven generator is all to adopt three, for simply thering is the tinsel of certain cambered surface, in the process of rotation, utilize the time of wind energy very short, and keep area windward also less, the seizure wind energy of three blades is undesirable, has so also caused the unsatisfactory shortcoming of wind power generator efficiency.
Below the present invention is described in further detail in conjunction with the accompanying drawings and embodiments again.

Five. embodiment
The present invention is to be 201020104231.4 in the patent No., on the basis of the utility model patent that invention and created name is " double-head wind driven generator ", improves, and improved technological scheme is to have improved blade fixed base.
Accompanying drawing 1 has provided the structural representation of the embodiment of the present invention 1.Referring again to other accompanying drawing.The present invention mainly comprises generator 12, be separately fixed at generator shaft 18 rear and front ends of generator 12 big fan 1 and small fan 11, be arranged at generator 12 front ends fixed window leaf 2 with turn active window leaf 3, rear and front end respectively with turn the connecting rod 4 that active window leaf 3 and sail 5 be connected, the sail 5 that is arranged at generator 12 tops and is connected with connecting rod 4.Big fan 1 and small fan 11 are arranged on respectively the termination, left and right of generator 12 axles, and generator 12 is arranged in vertical rod 15, and the urceolus of dressing generator 12 has hole can pass vertical rod 15, and generator 12 can be rotated around vertical rod 15.Sail 5 is fixing by sail fixing rod 8 and sail strut 10, the lower end of sail 5 is also provided with fixed base 6, fixed base 6 is provided with roller 7, be beneficial to reduce when connecting rod 4 drives sail 5 to seesaw resistance, bearing 9 is installed on sail fixing rod 8, fixed window leaf 2 is installed and turns active window leaf 3 near the front end of generator 12, on two gate leaves, have the window that several sizes are identical, wherein turning active window leaf 3 presses hard by generator 12, fixed window leaf 2 is pressed close in the outer end that turns active window leaf 3, one end of connecting rod 4 with turn active window leaf 3 and be connected, the other end is fixed on the below of sail 5, the electric energy that generator 12 is exported is filled with storage battery 14 by circuit conversion system 13 and stores, storage battery 14 can directly or by inverter be changed and supply with electric consumer use.
The present invention also has blade fixed base 23, and the bottom surface of blade fixed base 23 is rectangle, and near of the four edges of rectangle has the fixing tread 24 of blade of energy stator blade.
The bottom surface of blade fixed base 23 has neck bush, and it is fixing again that neck bush is inserted in generator shaft 18 ends, and blade fixed base 23 is fixedly connected with generator shaft 18 by neck bush.
Embodiment's fixing tread 24 have 3 can stator blade blade fixing threaded hole 27.
The embodiment of the present invention is work like this: four blades 26 are fixed on blade fixed base 23, and the root of each blade 26 passes blade fixing threaded hole 27 by screw blade 26 is fixed on the fixing tread 24 of blade.When wind direction is for the wind time, fixed window leaf 2 and the fixed window leaf window 16 that turns active window leaf 3 with turn active window leaf window 17 and align (as shown in Figure 5), just conventional moving the turning of generator 12 main shafts, electric energy is exported in generating; In the time that wind direction is contrary wind, connecting rod 4 is turned active window leaf 3 by sail 5 drives and turns over certain angle, make to turn active window leaf window 17 and cover fixed window leaf window 16 (as shown in Figure 6), like this, the reverse of generator 12 main shafts just can not occur, at this moment generator 12 main shafts have realized normal operation, continue generating output energy.Embodiment is owing to adopting four blades 26, and stator blade is reliably not easy to become flexible, and wind power generator efficiency is high, and cost is low.Adopt vertical rod fixed electrical machinery, the two ends of motor are provided with large small fan, do not need complicated component, realize so manufacture than being easier to, and be wind-driven generator practical, little investment.Also there is wind-force capturing ability strong, owing to having adopted big fan 1 and small fan 11, when air quantity hour, the just auxiliary big fan 1 of small fan 11 increases air quantity to reach strong wind energy power, embodiment 2 is also provided with wind direction angle-regulation structure simultaneously, guarantee that fan rotates and can not reverse to a direction all the time, thereby guarantee the continuous and stable of generating.Have safe and reliablely, the advantage of wide adaptability, is not subject to the impact of wind direction and region, can be in rural area, pasture, multiple areas, desert adopt.
