Description

A kind of vertical axis wind-mill generator

Technical field

The utility model relates to wind-driven generator, specifically a kind of vertical axis wind-mill generator.

Background technique

Current wind-driven generator is mainly divided into two kinds, and one kind is horizontal axis wind-driven generator, and another kind is vertical shaft wind Power generator.Horizontal axis wind-driven generator needs to be arranged yaw system, and stress can not disperse in the course of work, and wind loading rating is poor, And bearing usage quantity is more, causes that structure is complicated, cost is high and easily breaks down, in addition, horizontal axis wind-driven generator is in wind Speed is difficult to start when smaller, and most of time remains static, and wind energy utilization is very low.Vertical axis aerogenerator is divided into resistance Power type and two kinds of lift-type, lift-type rotation speed of fan is higher, and rotatory inertia is big, and structure is relatively easy, and cost is relatively low, but this structure Start when vertical axis aerogenerator brings into operation relatively difficult, especially behavior in service is poor in the lesser situation of wind speed； The advantages of resistance-type blower is that detent torque is larger, and starting performance is good, but its revolving speed is lower, and the utilization rate of wind energy is even Also less than horizontal axis wind-driven generator.

The document of application number 201410368026.1 discloses a kind of vertical axis aerogenerator, which uses fixed fan The mode of leaf collects wind energy, and the flabellum of the other side can also generate larger while when wind comes, side flabellum provides forward torque Reverse torque, therefore it is still very low for the utilization efficiency of wind-force.For another example the document of application number 200910012160.7 discloses A kind of vertical axis aerogenerator.This equipment, which passes through, to form a big flabellum with movable multiple folding units, although It is solved the problems, such as to a certain extent to wind power utilization efficiency, but its number of parts is big, structure is complicated, corresponding manufacturing cost It is also higher with maintenance cost.Therefore, design a kind of mechanism is simple, the operation is stable, high-efficient vertical axis wind-mill generator at For solving the problems, such as urgently.

Compared with prior art, the utility model beneficial effect is:

1, the flabellum that angle is 90 ° is fixed in the same flabellum axle, and flabellum axle can rotate horizontally, such two fans When the collocation of leaf group may be implemented windward side and reach maximum front face area, leeward side flabellum is just rotated into 0 ° of angle, hardly produces Raw reverse torque.Being disposed vertically multiple flabellum axles on the vertical axis makes the generation compared with the generating equipment of same size bigger Front face area, generating efficiency is significantly larger than the vertical axis wind-mill generator of fixed fan blade type.

2, the utility model greatly reduces in the quantity of movable flabellum, and the adjustment of flabellum is more rapid efficient, in structure It is upper simpler, it is stronger for the adaptability of high wind.It is hardly damaged, the cost for manufacturing maintenance is lower.

3, the design of gag lever post is used in the utility model, there is rubber in gag lever post position contacted with the fan blade, passes through limit Bar limits the rotational angle of flabellum, opens windward side flabellum no more than 180 °, leeward side flabellum will not be closed collision, ensure that The maximization of front face area improves the efficiency of wind-power electricity generation, avoids between flabellum, collision generation between flabellum and gag lever post Noise and vibration.

4, shaft coupling used in the utility model is yielding coupling, absorbs vertical axis by elastic element and passes over Vibration, reduction starting moment bring shock loading influence so that the operation of generator is more steady, working life is longer.

5, the friction for reducing vertical axis rotation by installation bearing improves operational efficiency, places and rolls in step The adverse effect of the radial force (horizontal direction active force) generated when equipment carrys out blowing-resistant can be improved in bearing, and thrust bearing is used To carry the weight (pressure of vertical direction) of vertical axis and flabellum, service life of a machine is improved.

6, the equipment solves the problems, such as generally existing inefficient of usual vertical axis wind-mill generator, vertical axis with Vibration problem and movable flabellum between generator shaft generate noise problem.The equipment is suitable for all suitable placement wind-power electricity generations The region of equipment, generating efficiency is high, and stable, structure is simple, low in cost.
