Description

The windmill of opening and closing leaves

The invention relates to a kind of windmill that utilizes wind-power electricity generation, this windmill can both be worked under the wind speed of several meters to tens meters of per seconds.

Existing horizontal axis propeller type windmill is to rely on the reaction thrust of wind to produce power, simultaneously, can not utilize wind-force in large area owing to be subjected to the restriction of this body structure.And it must be located on the high tower, therefore its economic benefit is quite limited, in addition, the economic benefit of vertical axis windmill is also quite limited, and its reason is that structure is too simple, and blade can not the box haul switch, when blade rotates with the wind, blade be large size facing the wind to producing power, when wind when blade rotates against the wind, blade is again that large size is facing the wind to producing resistance.So, offset greatly and rotate the power that produces with the wind on blade, the power of its rotation only is to rely on the wind small pressurized difference that (convex surface and concave surface) produced on the blade two sides, and therefore, business efficiency is quite limited.

The present invention provides a kind of blade rotary vertical axis windmill according to above-mentioned defective.This air vane can play box haul switch blade, thereby reduces resistance and increase the power of rotation, therefore, has improved the economic benefit of windmill greatly.

The windmill of box haul switch blade provided by the present invention is characterised in that: the radial direction at vertical windmill shaft, the identical windmill leaf frame of many Dimensionss is housed, and be provided with many subleaf frames in each leaf frame.Subleaf frame is made of with vertical inside casing horizontal inside casing, the hinge through of blade on the vertical inside casing that is installed in subleaf frame, except that the blade of leaf frame afterbody (that is: from windmill shaft position farthest) can be turned to the another side from the leaf frame afterbody, rest blade all can only change 180 °, and can with adjacent about two subleaf frames match.

Windmill is closed on the subleaf frame automatically in face of the blade of wind direction under wind-force, and produces and promote the power that windmill rotates.Carry the blade of wind-force and open from subleaf frame automatically, And and allow wind in the middle of the leaf frame by reducing the resistance of windmill rotation.

If change the sense of rotation of windmill, only need be contained in the front or the reverse side of leaf frame to blade together with subleaf frame, rotate with the clockwise direction and the counterclockwise direction that reach windmill.

In order to deal with the variation of wind direction, the afterbody of every fan leaf is all made the single face angle of subleaf frame dorsad, when wind direction changes, as long as wind power energy contact angle area.Blade is closed on the subleaf frame automatically and produces the power that windmill rotates that promotes.

The windmill of opening and closing leaves of the present invention can adopt different method for arranging to adapt to the variation of wind-force.For example: four typhoon car quadrates are arranged on four angles, and wherein two typhoon cars can be installed by Zhuan Dong And counter clockwise.Two typhoon cars can be installed by Zhuan Dong And in the direction of the clock in addition, and such layout can be useful under any wind direction and can both drag motor.Again for example: can be with tens even hundreds of typhoon car along area (belonging to two kinds of wind directions), it is two capable that along the coastline is arranged in, to adapt to the coastal area more.For the restricted area of erection space, can superpose windmill from level to level and build the windmill in a row of which floor or tens layers, promptly, multilayer windmill building in a row, certainly this huge building requires solid and reliable, for convenience maintenance, on this building, also to add necessary platform, for maintenance man's walking, surpass the windmill of safe altitude, also safety net to be set.

For the windmill of large-scale leaf frame, in order to alleviate the burden of leaf frame, with rib for example: steel plate is fixed on the leaf frame that does not have blade rotation by diagonal from top to bottom.

With reference to the accompanying drawings embodiments of the invention are explained:

In Fig. 1, the bottom of windmill pillar 1, be connected with windmill pedestal and annular ball plate 14, vertical rotation axis 2 is bearing on the pillar 1 by annular ball plate 14 and rotates, four radial direction at vertical rotation axis 2, be respectively equipped with the identical leaf frame 3 of 4 fan Dimensionss, be provided with subleaf frame 17 in leaf frame 3, this subleaf frame 17 constitutes (as shown in Figure 2) by horizontal inside casing 4 with vertical inside casing 5.Blade 10 by the hinge 8 on the vertical inside casing 5 that is fixed on subleaf frame 17 can pivot≤180 °; And and matching (as shown in Figure 3) with two adjacent subleaf frames, blade 11 can pivot about about 315 ° by hinge 9, it can be turned to the another side of leaf frame from leaf frame 3 afterbodys, but can not match (as shown in Figure 6) with this face leaf frame.Above-mentioned hinge 9 is fixed on the vertical inside casing 5 of subleaf frame 17 of leaf frame afterbody.Because blade 10 can rotate 180 °, so, under wind action, blade in face of wind direction is closed to (state of (1) shown in Fig. 4) on the subleaf frame automatically, and produce and promote the power that windmill rotates, off the wind to blade open (state of 2 shown in Fig. 4) from subleaf frame automatically, allow wind in the middle of the subleaf frame by to reduce resistance, improve the outputting power of windmill greatly.And blade 11 is turned to the another side of leaf frame by hinge 9 around pivot, its objective is for fear of large size to be subjected to the promotion of fitful wind and to damage, and after windmill rotated 180 °, blade 11 returned to the position (position as shown in Figure 6 (3)) of keeping out the wind hardly again.In addition, the position of blade 11 when calm is represented in position 4 shown in Figure 6.

In addition, in order to deal with the variation of wind direction, the single face angle 12(that every

fan leaf

10 or 11 afterbody are all made subleaf frame 17 dorsad as shown in Figure 2), when wind direction changes, as long as the area of wind power energy contact angle 12, just can make

blade

10,11 be closed to (position of as shown in Figure 5 (1)) on the subleaf frame 17 automatically, and generation promotes the power that windmill rotates, the blade of closing is simultaneously opened ((2) position as shown in Figure 5) from subleaf frame, and the position of (3) shown in Figure 5 is the position of blade wind-engaging, and is still constant thereby windmill turns to.

Simultaneously be provided with drift bolt 6 in certain of upper and lower horizontal inside casing 4, and lower limb is provided with and drift bolt 6 corresponding holes 7 on

blade

10,11, hole 7 on the

blade

10,11, not only to match with the drift bolt 6 on the corresponding subleaf frame 17, also want and can match with the drift bolt 6 on the adjacent subleaf frame 17, so, the hole 7 on the

blade

10,11 and the size of the drift bolt 6 on the subleaf frame 17 required, and the space is all consistent exactly, promptly requires good interchangeability (as shown in Figure 2).

If change the sense of rotation of windmill, only need be

blade
