Description
Technical field
The present invention relates to wind-driven generator field, is a kind of resistance type vertical shaft wind driven generator using honeycomb flap formula blade specifically.
Background technique
The technology path of vertical axis aerogenerator can be divided into the compound and pure resistance type of lift-drag two kinds, on the vertical shaft generation technology that lift-drag is compound, existing MW level unit is carrying out the industrialization prototype test stage, and the generating of pure resistance-type vertical axis is still in the small-sized stage.Existing vertical axis aerogenerator: if the patent No. is 200910012160.7, denomination of invention is vertical axis aerogenerator, in disclosed technology, its wind energy transformation rate is lower, and cause idle situation because the reasons such as deadweight cannot rotate in low wind conditions, if wind-force is comparatively large, there will be and occur damaging because of structural instability.The patent No. is 200910132493.3, and denomination of invention is a kind of vertical axis aerogenerator, discloses a kind of vertical axis aerogenerator lift being converted into starting torque.When wind-force is less, lift is more weak, and starting torque is less cannot starter-generator.
Summary of the invention
In order to solve the problem, the object of this invention is to provide the resistance type vertical shaft wind driven generator using honeycomb flap formula blade.
Technological scheme of the present invention is: it comprises: butterfly wind-engaging frames, is characterized in that: the even cloth of butterfly wind-engaging frames is on rotary sleeve, and rotary sleeve is fixed on turnbarrel axle, and turnbarrel axle is vertically fixed on pylon top; Described butterfly wind-engaging framework is fixed with cellular horizontal turnover panel framework, and each polygonal of cellular horizontal turnover panel framework is fixed with a horizontal turnover panel with a positive stop lug boss and by the little axle of level.
At least five even cloth of butterfly wind-engaging framework are on rotary sleeve.
The peripheral side of butterfly wind-engaging framework is curved.
Butterfly wind-engaging framework is fixed with sub-truss.
Described sub-truss is fixing horizontal boom beam on the rotary shaft, and horizontal boom beam is fixed bearing diagonal beam.
Under axisymmetric deployment scenarios, usually can there is static phenomenon when air-flow blows in two pieces of horizontal turnover panels.When using as wind-driven generator for this reason, need add and start equipment, initial starting moment is provided.
The present invention is one side device positive stop lug boss in cellular frame upper side, and when air-flow blows, it is full resistive state that draw-in groove (post) blocks turnover panel; And axisymmetric turnover panel can as front overturning when air-flow blows, in non-resistance ventilation state.
The resistance difference that resistance due to both sides turnover panel is different and produce, cause resistance side to be pushed, so whole wind energy conversion system starts to rotate, six pectinid power plates forward horizontal position successively to, and closed.Work is carried out in circulation and so forth.
The invention has the beneficial effects as follows and as long as there is minority turnover panel to work, just domino effect can occur bite, dead point phenomenon that many turnover panels solve single turnover panel and cause freezing, viscous to cause due to the factor such as weather, environment, drive whole turnover panel work.

Be described in further detail the present invention by example below in conjunction with accompanying drawing, but following example is only the present invention's example wherein, do not represent the rights protection scope that the present invention limits, the scope of the present invention is as the criterion with claims.
Embodiment
See Fig. 1, the even cloth of butterfly wind-engaging framework 1 is on rotary sleeve 2, and rotary sleeve is fixed on turnbarrel axle; See Fig. 2, turnbarrel axle is vertically fixed on pylon 3 top; Described butterfly wind-engaging framework is fixed with cellular horizontal turnover panel framework 4; See Fig. 3 ~ 4, each polygonal of cellular horizontal turnover panel framework is fixed with a horizontal turnover panel 6 with a positive stop lug boss 5 and by the little axle 8 of level.
Six even cloth of butterfly wind-engaging frames are on rotary sleeve.
See Fig. 2, the peripheral side curved 9 of butterfly wind-engaging frames is biomimetic features.
Butterfly wind-engaging frames is fixed with sub-truss 7.
Described sub-truss is fixing horizontal boom beam on the rotary shaft, and horizontal boom beam is fixed bearing diagonal beam.
Under axisymmetric deployment scenarios, usually can there is static phenomenon when air-flow blows in two pieces of horizontal turnover panels.When using as wind-driven generator for this reason, need add and start equipment, initial starting moment is provided.
The present invention is one side mounting limit boss in cellular frame upper side, and when air-flow blows, it is full resistive state that positive stop lug boss blocks horizontal turnover panel; And the horizontal turnover panel of axisymmetric side can as front overturning when air-flow blows, in non-resistance ventilation state.
The resistance difference that resistance due to both sides turnover panel is different and produce, cause resistance side to be pushed, so whole wind energy conversion system starts to rotate, six fan the butterfly be made up of cellular framework forwards horizontal position to successively by aerofoil, and horizontal turnover panel closes simultaneously.Work is carried out in circulation and so forth.
See Fig. 1,60 ° of angles, interval by aerofoil between be interconnected with T bar, the mid point of T bar is connected with tower top respectively with cable wire, the turnbarrel outside pylon, etc. rigidity overhang and the closed trigonometric form being connected cable wire and forming power.Thus structure stress is clear, calculates easy, safe and reliable, and the life-span is permanent, is convenient to safeguard.
The present invention can reach full landform (Coastal beach), and full-time sky (full annual utilization hours), full blast level effectively utilizes.
The invention has the beneficial effects as follows and as long as there is minority turnover panel to work, just domino effect can occur bite, dead point phenomenon that many turnover panels solve single turnover panel and cause freezing, viscous to cause due to the factor such as weather, environment, drive whole turnover panel work.
Its working principle is according to the different conditions of turnover panel horizontal in cellular framework in the both sides of pylon, and in situation breezy, the side limited projection of horizontal turnover panel is blocked, and forms wind-receiving face; Opposite side turn to horizontal position, makes distinguished and admirable unimpeded mistake.So just forming the limited projection in side respectively stuck, is full resistive state by aerofoil; At the cellular framework of its respective side, overcome the deadweight of horizontal turnover panel by wind, plumbness is become the ventilation state upwards dug.The resistance of the cellular framework of full resistive state reaches maximum, and minimum with the cellular framework resistance under the ventilation state of its symmetry, thus forms the resistance difference of both sides, finally causes wind energy conversion system to rotate around pylon.Other type wind energy conversion system requires that the above wind speed of 2.5 meter per second could start, and patent wind energy conversion system of the present invention just can start at 0.5 meter per second.
Operationally only to the vertical torque of pylon transmission and gravity, there is no moment of flexure, therefore can continue to run under high wind speed, 12 ~ 14 grades of high wind can be resisted, wind energy conversion system type can be selected for China's southeastern coast provides.Thus greatly improve vertical axis windmill wind energy utilization efficiency, exceed the theoretical wind energy utilization efficiency of current horizontal-shaft wind turbine.
