Description

Full blast can the low-cost generator of elasticity fan blade

Affiliated technical field

The utility model relates to the improvement and the integrally-built adjustment of power-driven generator leaf part, and promptly full blast can the low-cost generator of elasticity fan blade.

Background technique

The fan blade of common wind-driven generator is to facing the wind in front, form by three blades mostly, because blade is very narrow and quantity is few, so the area summation of fan blade is just very little, the air quantity of the wind energy that receives certainly is also just very little, makes utilization ratio of wind energy very low, has only few wind-force acting, this is that the air quantity that receives is directly proportional with the area of fan blade again because the size of wind energy is directly proportional with the product of air quantity and wind speed; 3 common fan blade generators, the wind-exposuring area of its fan blade has only about the 5%-7% of the whole area of a circle, to such an extent as to generator can not rotate when wind-force is little; Yet in fact, nature has only less wind-force in most of the time, that is to say the not utilization of most wind energy.Yet fan blade is compelled to do very narrowly again, otherwise do not had the effect of rotation down with the wind, in order to improve the area of fan blade, it is very long that its fan blade must be done again, and it is very high that this just requires that support does, add that fan blade is straight plate structure, in the time spent of doing that is subjected to wind-force, very big near the blade moment of axial region, blown folding by high wind easily, requirement of strength to material is just very high like this, makes cost increase considerably.Fan blade can produce centrifugal force when rotating in addition, forces air to slide to the periphery, has further reduced the wind energy of acting.

Summary of the invention

In order to solve the higher problem of cost that wind energy utilization is low and solution causes greatly because of the fan blade moment, the utility model provides a kind of full blast energy elasticity fan blade low-cost generator, this wind-driven generator not only can do work under less relatively wind-force, and can reduce cost.

The technological scheme that its technical problem that solves the utility model adopts is: large-area elasticity fan blade is housed on horizontal axis, comprise the fan blade lacing wire simultaneously and through broadwise elasticity fan blade skeleton, generator is fixed with fixed card and stand type support and rotating vertical shaft, it is characterized in that: the fan blade group is made up of a plurality of blades, blade material is the elastic resin sheet structure, with lacing wire and the stable system of elastic skeleton be combined into, it is wide that blade can be done, its area that receives wind energy can reach more than 80 of the whole area of a circle, so that improve the utilization ratio of air quantity.

Whole generator Structure feature is the back that fan blade is installed in generator, so that the structure and the axle of umbrella are fixed.Blade and horizontal axis have an angle of inclination, and best angle is between 70 °～90 °, to eliminate the phenomenon that fan blade forces air to slide to the periphery when rotating.Fan blade is strengthened by lacing wire with axle, forms the intensity that stable trigonometric form structure can improve the uprising wind of fan blade like this.Adjust lacing wire and skeleton and just can make fan blade be folded into column structure, be convenient to transportation like this by disc-shape.The angle of fan blade and wind direction is between 100 ° of-170 ° of degree, the size of its angle is regulated according to the size of wind-force automatically by elastic skeleton, and when wind-force was less, its angle was also little, slight wind can receive large-area wind energy like this, so even also can make it rotate acting.When wind-force was big, elastic skeleton made angle also become greatly under the wind-force effect, and the area that receives wind energy just reduces, and can protect fan blade to be difficult for being fractureed by strong wind like this, and the support of generator also is difficult for being blown by storm wind bad, thereby significantly saves cost of material.

The technological scheme that the utility model further solves its technical problem and adopted is: in order further to reach the purpose of breeze wind, the winding of generator is according to the size fractionation generating of wind-force, measure is that winding adopts 3 to organize coil mutually, and inside can be wye connection, also can be delta connection; Second group of coil and the 3rd group of coil insert the voltage cut-out of different voltages respectively, in order to the conducting of control wiring; Less wind-force occurs under most of situation, at this moment have only first group of coil conducting generating, generator can move like a cork.When wind-force acquired a certain degree, the rotating speed of generator and voltage thereof were also brought up to a certain degree, and this moment, the voltage cut-out of second group of coil was open-minded, and generated energy increases.When wind-force further strengthens again, then the voltage cut-out of the 3rd group of coil is open-minded, this moment the generated energy maximum, the purpose that can both generate electricity from gentle breeze to high wind of realization like this, promptly full blast can generate electricity.Voltage cut-out can adopt SCR control, also can be by centrifugal change control.

The low-cost generator of the utility model full blast energy elasticity fan blade connects large-area elasticity fan blade on horizontal axis, can do work under weak wind; Because the skeleton of fan blade has elasticity, so can regulate the angle of facining the wind automatically, make voltage relatively stable along with the size of wind-force, can protect the integral body of generator not blown bad simultaneously by storm wind; Fan blade is strengthened by lacing wire with axle, to form stable trigonometric form structure; Coil adopts the method for classification generating, with the conducting of voltage cut-out automatic control circuit, with the purpose that realizes that full blast can generate electricity; The utility model generator utilization ratio of wind energy height, weak wind and high wind can both make its generating, and are convenient to transportation, and cost is low, is suitable for various large, medium and small types wind power station.

Embodiment

In Fig. 1, generator (1) and rotating vertical shaft (3) card (2) that is fixed is fixing, at last and support (10) link into an integrated entity.Generator shaft and horizontal axis (5) are fixed together, and at the end connection elasticity fan blade (8) of horizontal axis (5), elasticity fan blade (8) constitutes the elasticity blade by broadwise elasticity fan blade skeleton (7) and warp-wise fan blade skeleton (9), is strengthened by lacing wire (6) again.

During operation, wind is to rotor machine, and the combination of its elasticity fan blade (8) and horizontal axis (5) thereof makes vertical shaft (3) turn to suitable position under leverage, and elasticity fan blade (8) drive horizontal axis (5) rotates together and makes generator (1) generating.Because the area of fan blade (8) is very big, again because when the slow-speed of revolution, 2 voltage cut-outs (12) are all not conductings also, 3 organize coil mutually has only 1 group can generate electricity, so as long as have slight wind-force just can make its acting simultaneously.When wind-force (4) strengthens; broadwise elasticity fan blade skeleton (7) makes the fan blade (8) and the angle of wind direction (4) also become big under the effect of wind-force (4); the area of the wind energy that receives just reduces; can protect the supporting frame (10) of fan blade (8) and generator (1) to be difficult for by big wind disconnected like this; voltage cut-out (12) is also along with the automatic conducting effect of adjusting coil (11) of the size of wind-force (4); when wind-force (4) strengthens; 2 voltage cut-outs (12) conducting one by one; generated energy is increased automatically, thereby realize the purpose that full blast can generate electricity.
