Abstract

The utility model relates to a high-efficient wind motor, which is composed of blades, a vertical shaft, and a generator. The blades are assembled by a blade frame and a plurality of movable small blades. Every small blade is connected with the blade frame through a supporting point. Simultaneously, every small blade can swing or rotate round the supporting point. Because the utility model adopts a light, movable, and variable type blade structure, the blades can increase push force and reduce resistance in working. Every blade is in a ladle shape. The utility model further increases pneumatic push force and reaches the purpose of increasing the use rate of wind energy.

Description

High-efficient wind turbine

The utility model belongs to a kind of novel wind motor.

Be used for the wind motor (also claiming windmill) of wind-power electricity generation at present, two classes are roughly arranged: a class is horizontal shaft type, adopts propeller formula blade.Another kind of is perpendicular axis type, and blade is a wind sail type.The blade back produces eddy current during the work of first kind windmill, forms certain resistance, and needs to install the direction that tail vane is adjusted windmill; Resistance was also bigger when blade entered the contrary wind of backhaul district during the work of the second class windmill.Thereby all there is the defective that the wind energy loss is big, efficient is not high in these two kinds of windmills.

The purpose of this utility model provides a kind of new and effective wind energy conversion system, and it can reduce the loss of wind energy, improves pneumatic efficient.

The utility model is made up of fan blade, vertical pivot, generator, and fan blade is assembled by leaf frame and some movable small leaf, and each small leaf links to each other with the leaf frame by fulcrum, and simultaneously, each small leaf can rotate or swing around fulcrum.

The utility model can increase thrust owing to adopt lightweight activity changable type blade structure when making fan blade work, reduces resistance, and each fan blade is a spoonful shape, further improves pneumatic thrust, reaches the purpose that improves Wind Power Utilization efficient.

As shown in Figure 1, the utility model is made up of fan blade 2, vertical pivot 3, generator 9, and fan blade 2 is selected four for use, and symmetry is fixed on the vertical pivot 3, and vertical pivot 3 joins with generator shaft again.Each fan blade 2 is assembled by leaf frame 4 and some movable small leaf 5, and each small leaf 5 links to each other with leaf frame 4 by fulcrum 6, and simultaneously, each small leaf 5 can rotate or swing around fulcrum 6 in the fan blade rotation process.

As shown in Figure 1 and Figure 2, be this case embodiment 1 blade structure schematic representation.Fan blade 2 among the figure is a spoonful sigmoid, constitute by leaf frame 4 and some flag shape small leaf 5, leaf frame 4 bottoms in bending, rack 7 is set, evenly be provided with little axle 6 on the leaf frame 4 at certain intervals, little axle 6 two ends are connected with bearing with the horizontal frame of leaf frame 4, between little axle 6 and the little axle 6, be space 8, little axle 6 is vertical setting, and it constitutes the fulcrum 6 that small leaf 5 links to each other with leaf frame 4, small leaf 5 is square, one vertical edge edge is connected on the little axle 6, and small leaf 5 can rotate or swing around little axle 6, and rotational angle or angle of oscillation are not more than 90 °.Its working principle is as follows: when fan blade 2 rotates to when distinguishing around vertical pivot 3 with the wind, the small leaf 5 on the fan blade 2 goes to the rack of being close in the leaf frame 47 and closes space 8 around little axle 6, and whole fan blade 2 forms stuffy state, and the blade face blowing area increases, and its thrust is also big; When fan blade 2 rotates to when distinguishing against the wind, the small leaf 5 on the fan blade 2 opens automatically around little axle 6, constitutes a right angle with leaf frame 4, reserves space 8, and fan blade 2 is in ventilative state, and wind can pass from space 8, and the blade face blowing area reduces, and its resistance is also little.So circulation, thereby by reducing pneumatic resistance and increasing the efficient that pneumatic thrust improves wind energy conversion system.

As Fig. 4, shown in Figure 5, be this case embodiment 2 blade structure schematic representation.Be horizontally arranged with crosspiece 11 on the leaf frame 4, along vertically being provided with perpendicular shelves 12, be separated out number row vent hole 13 by crosspiece 11 and perpendicular shelves 12, frame around each vent hole 13 constitutes the fulcrum 6 that small leaf 5 links to each other with leaf frame 4, and small leaf 10 is made cross section and vent hole 13 equiform cylinder, claims tubular small leaf 10, tubular small leaf 10 1 ends are fixed on the frame, the other end opening is outside, can swing around frame, and pivot angle is not more than 90 °.Tubular small leaf 10 usefulness soft materials (as rain repellent silk etc.) are made, its working principle is as follows: when fan blade 2 rotates to when distinguishing with the wind, tubular small leaf 10 on the fan blade 2 goes to the vent hole of being close in the leaf frame 4 13 and closes vent hole 13 around frame, whole fan blade 2 forms stuffy state, the blade face blowing area increases, and its thrust is also big; When fan blade 2 rotates to when distinguishing against the wind, tubular small leaf on the fan blade 2 10 opens rapidly around frame, constitutes a right angle with leaf frame 4, and fan blade 2 is in ventilative state, and wind can pass from vent hole 13, and the blade face blowing area reduces, and its resistance is also little.So circulation, thereby by reducing pneumatic resistance and increasing the efficient that pneumatic thrust improves wind energy conversion system.

As shown in Figure 6, be this case embodiment 3 structural representations.Fan blade 2 is made of compound leaf frame 4 and small leaf 5, compound leaf frame 4 is made of at least three horizontal frames 15 and corresponding munnion 16, between per two horizontal frames 15, evenly be provided with little axle 6 at certain intervals, little axle 6 two ends and horizontal frame 15 are connected with bearing, on the little axle 6 small leaf 5 is housed, small leaf 5 is square, can rotate around little axle 6.
