The upper frame of the top of described air door 2 and air door 3 flexibly connects, can be in a side of air door 3 be that radius stirs up and down with the top for axis bottom.
During windmill work, being fixed on several rotating bladings 5 on the vertical shaft 1, under the blowing of wind, is that rotate in the axle center with vertical shaft 1.When the sense of rotation of rotating blading 5 is consistent with wind direction, air door 2 on the air door 3 is promoted by wind, air door 2 is that axis rotates from top to bottom with the top, blocked by backing pin 4, and be the shut the gate state for air door 3 air doors 2, air door 2 on the rotating blading 5 on all air doors 3 is all closed, be in the shut the gate state, wind just can't be blown over rotating blading 5, and rotating blading 5 has maximum blowing area, accept maximum wind energy, the moving rotating blading 5 of wind rotates around vertical shaft 1; When the sense of rotation of rotating blading 5 (is rotated against wind) on the contrary with wind direction, air door 2 on the air door 3 is promoted by wind, air door 2 is that axis stirs from bottom to top with the top, air door 3 air doors 2 are " opening the door " state, air door 2 on the rotating blading 5 on all air doors 3 is all opened, and is in " opening the door " state, and wind is not subjected to resistance ground by air door 3, rotating blading 5 has minimum blowing area, reduces to amplitude peak frontal resistance.
The utility model is simple in structure, the better utilization power of facining the wind, and effectively reduce revolution strength against the wind, and increase rotation wind-force, be adapted at use various environment under.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Embodiment one: referring to Fig. 1, this embodiment is by the following technical solutions: it comprises vertical shaft 1, air door 2, air door 3, backing pin 4 and rotating blading 5; The periphery, upper end of vertical shaft 1 is provided with 2 or 2 above rotating bladings 5, rotating blading 5 is made up of several air doors 3, air door 2 is installed on each air door 3, the upper frame of the top of air door 2 and air door 3 flexibly connects, the side of air door 3 and bottom are provided with several backing pins 4, also can be baffle plate, pin etc.Described rotating blading is two limits and outer side about in the of 5, and the backrush side plate is all arranged, and the angle of backrush side plate and rotating blading 5 is that 90 degree are between 175 degree.The upper frame of the top of described air door 2 and air door 3 flexibly connects, can be in a side of air door 3 be that radius stirs up and down with the top for axis bottom.
During windmill work, being fixed on several rotating bladings 5 on the vertical shaft 1, under the blowing of wind, is that rotate in the axle center with vertical shaft 1.When the sense of rotation of rotating blading 5 is consistent with wind direction, air door 2 on the air door 3 is promoted by wind, air door 2 is that axis rotates from top to bottom with the top, blocked by backing pin 4, and be the shut the gate state for air door 3 air doors 2, air door 2 on the rotating blading 5 on all air doors 3 is all closed, be in the shut the gate state, wind just can't be blown over rotating blading 5, and rotating blading 5 has maximum blowing area, accept maximum wind energy, the moving rotating blading 5 of wind rotates around vertical shaft 1; When the sense of rotation of rotating blading 5 (is rotated against wind) on the contrary with wind direction, air door 2 on the air door 3 is promoted by wind, air door 2 is that axis stirs from bottom to top with the top, air door 3 air doors 2 are " opening the door " state, air door 2 on the rotating blading 5 on all air doors 3 is all opened, and is in " opening the door " state, and wind is not subjected to resistance ground by air door 3, rotating blading 5 has minimum blowing area, reduces to amplitude peak frontal resistance.
For avoiding strong wind to cause the windmill rotating speed out of control, described backing pin 4 can switch between two states, and a state is " opening " state, another state is " closing " state, at " opening " state, makes it can block air door 2, at " closing " state, do not block air door 2.During normal controlled wind speed, control backing pin 4 is in " opening " state, can control the range of movement of air door 2, and it is moving in a rollover of air door 3 to block air door 2; During strong wind; in order to protect air door 2 damage by draggings; control backing pin 4 is in " closing " state, no longer controls the range of movement of air door 2, and air door 2 can stir in air door 3 both sides; no matter be that rotating blading 5 is in and rotates a side with the wind or rotate a side against the wind; air door 2 all no longer keeps out the wind, and wind can pass through air door 3 smoothly, and the wind-force that rotating blading 5 is subjected to has reduced; the windmill rotating speed is slow, has protected windmill integral body.
This embodiment is simple in structure, the better utilization power of facining the wind, and effectively reduce revolution strength against the wind, and increase rotation wind-force, be adapted at use various environment under.
Embodiment two: this embodiment is with the difference of embodiment one: the air door 2 of described windmill also can design as follows, rotating blading 5 numbers on the vertical shaft 1 are even number, and settle with vertical shaft 1 axisymmetric, against the wind a side and with the wind the rotating blading 5 of a side locate in twos at grade, hereinafter to be referred as " a pair of rotating blading ", can become small angle to be placed on a pair of rotating blading a plurality of transversely arranged air door 3 levels or with level so, be called " one group ", air door 2 series connection on this group air door 3 are fixed on the major axis, the long door-hinge of these a plurality of air door 2 shared these roots, the long door-hinge of this root is near the upper frame of air door 3, its length can be that these two are changeed fan blade 5 width sums, and it had both passed with the wind that " one group " air door 2 of a sideway swivel fan blade 5 also passes " one group " air door 2 of a sideway swivel fan blade 5 against the wind.Wherein against the wind on the sideway swivel fan blade 5, series connection fixes that the angle between a plurality of air doors 2 is 0 on this root major axis, with the wind on the sideway swivel fan blade 5, series connection fixes that the angle between a plurality of air doors 2 is 0 on this root major axis, but against the wind a plurality of air doors 2 on the sideway swivel fan blade 5 and with the wind the angle between a plurality of air doors 2 on the sideway swivel fan blade 5 between the 60-100 degree.For a pair of rotating blading, with the wind on the sideway swivel fan blade 5, series connection fixes that a plurality of air doors 2 are applied a power by wind on this root major axis, promoting a plurality of air doors 2 closes, be in vertical state, this power is rotated the major axis on the fixing a plurality of air doors 2 of series connection, this major axis rotate drive on sideway swivel fan blade 5 against the wind, series connection fixes on this root major axis a plurality of air doors 2 and opens, and is in the level of approximation state.When a sideway swivel fan blade 5 forwarded contrary wind one side to the wind, a plurality of air doors 2 on the rotating blading 5 circulated and so forth by side mark rule motion against the wind, make not stall of windmill moving.
