Description
Technical field
It is the device of electric energy with wind energy transformation that the utility model relates to a kind of, relates to a kind of windmill specifically, is primarily aimed at the windmill fan blade and makes improvement.
Background technique
This life circle, various countries comprised that the windmill that large-scale wind generating equipment that China develops is adopted all adopts traditional horizontal axis three leaves or two leaves, and well-known, the best approach that windmill improves wind energy utilization is: the wind comes from of (1) any direction can both utilize.(2) increase the fan blade blowing area, utilize wind energy directly to promote windmill to greatest extent and improve utilization ratio of wind energy.But the traditional windmill that generally uses must be sought wind direction with weathercock and adjust windmill angle tracking wind direction by mechanical transmission now, and the next of fan blade wind-receiving face and wind changes the action direction of wind-force to an angle is arranged, and fan blade is generally lower to utilization ratio of wind energy.
The model utility content
Problems such as the utility model is at the deficiency that prior art exists, and a kind of do not have weathercock, windmill that resistance is little are provided, and seeks wind direction when overcoming existing windmill work, and the fan blade blowing area is little improve the wind energy utilization of windmill.
For solving the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of vertical type windmill, comprise fan blade, base and be vertically set on the body of rod on the described base, it is characterized in that, but described body of rod top is provided with the transverse axis of 3-6 bar distaff body rotation, described transverse axis end is provided with the blade face fan blade parallel with the described body of rod, the lee face of the fan blade on the windward side of the fan blade on one of them transverse axis and the adjacent transverse axis is relative, and this fan blade comprises some blades, is provided with the stop device that stops described blade to float towards to lee face on the lee face of fan blade.
Further, the utility model also has following technical characteristics: described stop device comprises some montants of fixedlying connected with described transverse axis.
Further, the utility model also has following technical characteristics: described stop device comprises the wire netting of fixedlying connected with described transverse axis.
Further, the utility model also has following technical characteristics: described blade is the strip that is arranged in order.
Further, the utility model also has following technical characteristics: described blade is transversely arranged.
Further, the utility model also has following technical characteristics: described fan blade integral body is louvre type.
Further, the utility model also has following technical characteristics: described transverse axis is a lineal shape.
Further, the utility model also has following technical characteristics: described fan blade is square.
Further, the utility model also has following technical characteristics: described transverse axis is an arc, and described fan blade vertical sectional shape is corresponding with described transverse axis shape.
Compared with prior art, advantage of the present utility model and good effect are as follows:
The utility model is when running into different wind directions, all fan blades can be according to the automatic adjusting angle in the position of oneself, when the windward side of fan blade facings the wind, blade is under the effect of stop device, be close to stop device, promote whole fan blade and rotate, because blade is that wind is met in the front head-on, thereby the wind-force that is subjected to is bigger, thereby faster rotational speed; When the lee face of fan blade facingd the wind, blade was blown afloat, and had weakened the strength of the moving fan blade of wind.
The utility model is reasonable in design, and high working efficiency is rotated flexibly, and blade exchanging is convenient, can effectively utilize the wind comes from of all directions, and output power is big.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Embodiment one, referring to Fig. 1, present embodiment vertical type windmill, comprise fan blade 4, base 1 and be vertically set on the body of rod 2 on the described base, but the body of rod 2 tops evenly are provided with the straight line type transverse axis 3 of 4 distaff body rotations, promptly four transverse axis 3 are the decussation arrangement, described transverse axis 3 ends are provided with the parallel fan blade 4 of blade face and the described body of rod 2, present embodiment fan blade 4 is square, the lee face 6 of the fan blade 4 on the windward side 9 of the fan blade 4 on one of them transverse axis 3 and the adjacent transverse axis is relative, this fan blade 4 comprises some blades, and described blade 4-1 is vertical strip, from left to right is arranged in order.Be provided with the stop device that stops described blade 4-1 to float towards to lee face 6 on the lee face of fan blade 4, the present embodiment stop device is some montants 5 of fixedlying connected with described transverse axis 3.
Present embodiment windward side and lee face are defined as follows: during fan blade 4 wind-engagings, the face that can be pushed is the windward side; During wind-engaging, the face that the blade of fan blade is blown to its opposing face is a lee face.
During work, referring to Fig. 5, false wind blows from the dead ahead, and the montant that blade on the fan blade of wind is close to the back is met in the front head-on, with described fan blade another fan blade on same straight line just in time lee face meet wind head-on, at this moment, blade on the fan blade hikes up to the direction of its windward side, thereby this moment, wind was less to its Driving force, like this, fan blade is under wind action, and windmill turns clockwise.
When wind takes over direction when blowing in the past, the wind-force that the fan blade windward side is subjected to is less, adjusts a lower angle under less wind action earlier, and the front, windward side to one of them fan blade to be adjusted begins high speed rotating when meeting wind head-on.
Certainly, transverse axis 3 can be set to 6, also can be set to 3 or 5, and structure is to above-mentioned similar, and this does not give unnecessary details.
Embodiment two, referring to Fig. 2, are that with embodiment one difference the present embodiment stop device is the wire netting 7 of fixedlying connected with described transverse axis, and fan blade is horizontal strip, is arranged in order from top to bottom, adopt the sun-proof oilcloth of waterproof to make.
Embodiment three, and referring to Fig. 3, be with embodiment one, two difference: present embodiment fan blade integral body is louvre type, and the blade on the fan blade can only be towards a direction rotation, promptly when described fan blade facings the wind, and blade 8 closures; When leeward, blade 8 is opened, and weakens the blow power of wind to fan blade.
Embodiment four, referring to Fig. 4, the difference of the various embodiments described above is, this enforcement transverse axis 3 is an arc, described fan blade vertical sectional shape is corresponding with described transverse axis shape, and the blade lee face is provided with wire netting, the horizontal cloth of windward side upper blade for being arranged in order up and down, in order to know indication structure, not shown blade.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
