Technical field

The utility model relates to and a kind of wind power transformation is become the device of mechanical rotation, and particularly a kind of vertical shaft type is the device of mechanical rotation with wind power transformation.

Background technique

Wind energy is a kind of transition form of solar energy, is inexhaustible, particularly in being converted to the process of electric energy, does not produce any harmful gas and waste material, and is free from environmental pollution, and having gathers materials on the spot does not need characteristics such as transportation.

At present, the most general way is to utilize wind-power electricity generation, and existing wind-driven generator is generally the generator of horizontal shaft type.Its wind foce conversion equipment is a level, and promptly rotatingshaft is a horizontal positioned.This wind-driven generator must have yawing mechanism, but also whole wind power generating set need be brought up to cat head, and in addition, generator and control regulating device all are placed on cat head and cause difficulty to maintenance.

The vertical-shaft wind-power machine main product is: Frenchman G.J.M.Darrieus is at the vertical shaft type Dai Ruisi wind energy conversion system of invention in 1931, and the rotatingshaft of its wind foce conversion equipment is vertical.This wind energy conversion system is compared with horizontal shaft type wind energy conversion system, and simple in structure, cost is low, the wind energy utilization height, but it also has following defective: when not having auxiliary device, and own fail to start; Generally to surpass more than the 5m/s, just can send power at wind speed.

The model utility content

The purpose of this utility model provides the defective that overcomes prior art, and a kind of novel wind foce conversion equipment is provided.

The purpose of this utility model is achieved through the following technical solutions:

A kind of wind foce conversion equipment comprises a vertical rotatingshaft, is provided with at least three poles on this rotatingshaft top, and respectively the activity of going up of this pole all is connected with one and only can and turns to identical blade around the pole one-way rotation that is connected.

Respectively this blade can also be suspended on its place pole, and links to each other with adjacent pole in turn by rope.

In addition, respectively this pole being the state that is evenly distributed link to each other with this rotatingshaft.

Positive progressive effect of the present utility model is: cost is low, easy construction, easy to maintenance, energy conversion efficiency is high, the wind speed wide accommodation.

Embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

First embodiment

As shown in Figure 1, 2, a kind of wind foce conversion equipment, comprise a vertical rotatingshaft 1, be provided with in the upper end of this rotatingshaft 1 three

poles

2,2 ', 2 "; respectively the state that is evenly distributed links to each other with this rotatingshaft 1 this pole being; respectively be connected with on this pole a

blade

3,3 ', 3 ", but respectively this blade rotates around place pole.As shown in Figure 5, below this pole respectively, be equipped with a stopper protrusion 21, make that this blade only can be around the pole one-way rotation at its place, and respectively this blade is located at the homonymy of this stopper protrusion 21.Respectively this blade is plate shaped blade.

Be provided with a spacing preiection 22 at the horizontal position of this pole respectively and at the homonymy of this stopper protrusion 21, be used to limit the slewing area of this blade.As shown in Figure 5, this blade is located between this stopper protrusion 21 and this spacing preiection 22.

This stopper protrusion 21 and this spacing preiection 22 can be embarked on journey with the pole one at place.And, can be only be provided with this stopper protrusion 21 and this spacing preiection 22 a certain section or a few sections of place pole, can play the effect that limit blade is rotated equally.

When wind during to this wind foce conversion equipment, as shown in Figure 2, W is a wind direction, at least have two blades 3,3 ' be positioned at the windward side, blast acts on blade 3,3 ' on will produce an active force, and then produce one around pole 2,2 ' moment, make blade have the trend of rotating around pole, one of them blade 3 is owing to blocked and can not rotate by this stopper protrusion 21, the active force that blast produces just is delivered on the pole 2, another blade 3 then can be around pole 2 ' rotation, as Fig. 4, shown in 6, thus the active force that produces of blast just do not act on pole 2 ' on.Like this, just produce the moment of the moving axis 1 that rotates, make this rotatingshaft rotate, when turning over several angle, promptly when two blades that facing the wind change, in like manner also can produce above-mentioned moment, make that this rotatingshaft continues to rotate.

Second embodiment

Shown in Fig. 7,8, a kind of wind foce conversion equipment, comprise a vertical rotatingshaft 1, be provided with in the upper end of this rotatingshaft three poles 4,4 ', 4 "; respectively the state that is evenly distributed links to each other with this rotatingshaft 1 this pole being, respectively the below of this pole be hung with a blade 5,5 ', 5 ", respectively this blade pass is crossed a rope 6 that is connected in its underpart and is connected with adjacent pole in turn, as shown in Figure 8, and rope 6 be connected the neutral position of the end of pole and blade bottom.Respectively this blade is plate shaped blade.

When wind during to this wind foce conversion equipment, as shown in Figure 7, at this moment, at least have two blades 4,4 ' be positioned at windward side, blast acts on will produce an active force on the blade, and then produce a moment around pole, make blade have the trend of rotating around pole, one of them blade 4 ' owing to held and can not rotate by described rope 6, so, the active force that blast produces just is delivered on the pole, and another blade 4 then can rotate around pole, thereby the active force that blast produces does not just act on the pole.Like this, just produce the moment of the moving axis 1 that rotates, make this rotatingshaft 1 rotate, when turning over several angle, promptly when two blades that facing the wind change, in like manner also can produce above-mentioned moment, make that this rotatingshaft continues to rotate.

The 3rd embodiment

Shown in Fig. 9,10, present embodiment is different with first embodiment to be: three poles 7 comprise outer cover 71 and the inner shaft 72 that is located in this skin cover 71, and this inner shaft 72 rotates in this skin cover 71, on this skin cover 71 breach is arranged.The blade 8 that is connected on the pole 7 links to each other with this inner shaft 72, and blade 8 only can rotate mouth in the scope of breach.This inner shaft 72 also can only have part sheathed should skin cover 71, can realize equally limiting the purpose that this blade 8 rotates, figure does not show.

The 4th embodiment

As Figure 11,12, present embodiment is that with above-mentioned first, second or the different of the 3rd embodiment described blade is a curved surface bucket 9.One end of curved surface bucket 9 is provided with baffle plate 91, is used for choked flow and support blade.During installation, an end that is provided with baffle plate 91 is away from this rotatingshaft.

The 5th embodiment

Present embodiment is with first, second or the different of the 3rd embodiment: this wind foce conversion equipment comprises four poles 100, respectively is connected with a blade on this pole, as shown in figure 13.

The 6th embodiment

Present embodiment is with first, second or the different of the 3rd embodiment: this wind foce conversion equipment comprises six poles 110, respectively is connected with a blade on this pole.As shown in figure 14.

In the various embodiments described above, respectively the sectional shape of this pole can make multiple shapes such as circle, square, triangle, and respectively the sectional shape of this pole can be identical, also can be different, respectively this pole also can be one-body molded with this rotatingshaft, respectively also can be integrated formed structure between this pole.These variations all within the utility model scope required for protection, do not repeat them here.
