Embodiment one
With reference to Fig. 1-3, wind power-generation integrated machine with soft magnetic fan-leaf described in the utility model comprises the vertical shaft fan 7 of soft magnet material, and described vertical shaft fan 7 is installed between the fan seat 2 of the fan lid 1 on top and bottom by axle 13 and bearing 12.Described fan lid 1 is installed on the fan seat 2 by four decks 14.The inboard of described fan lid 1 and fan seat 2 is respectively equipped with first permanent magnet 3 and second permanent magnet 4, and the polarity of the inner side surface of described first permanent magnet 3 and second permanent magnet 4 is different.Between the outer side surface of described first permanent magnet 3 and second permanent magnet 4, by this wind generator all-in-one machine middle fan lid 1 and fan seat 2 four jiaos are connected with a magnetic conduction soft magnetic bodies 8, and this soft magnetic bodies is a sheet metal part.Magnetic conduction soft magnetic bodies 8, first permanent magnet 3 and second permanent magnet 4 by up and down totally 16 decks 15 be fixed on fan cover 1 or fan 2 on.Described soft magnetic material is that very little (ferromagnetic material of HC＜102A/m) is made by coercivity.Because the coercivity of this material is little, thus magnetization easily, also demagnetization easily, hysteresis loss is little, is fit to use in the alternating magnetic field.Material such as pure iron, silicon steel all is a soft magnetic material.Because this device often is applied to the open air, so these soft magnetic materials have certain anticorrosive property, surface plating one deck rust resisting compound gets final product.The inner side surface of described first permanent magnet 3 and second permanent magnet 4 is equipped with groove 5, lays coil 6 in the groove 5, and coil 6 can adopt bonding mode to fix.Each flabellum 11 on the described vertical shaft fan 7, different with common flabellum, flabellum upper limb 9 and flabellum lower edge 10 are arranged, and the area of flabellum upper limb 9 projection on fan seat 2 in projection on the described fan lid 1 and flabellum lower edge 10 equals the area of described groove 5, and its shape is coupling mutually also.Groove on described first permanent magnet 3 and second permanent magnet 4 has the several angle difference to react the differential seat angle between described flabellum upper limb 9 and the flabellum lower edge 10.6 of described coils should be connected in series, and the serial connection direction should guarantee that when fan rotates the electromotive force of each coil generation do not cancel each other.Get back to first permanent magnet 3 from described first permanent magnet 3, magnetic conduction soft magnetic bodies 8, second permanent magnet 4, vertical shaft fan 7 and form the closed main magnetic circuit that has two small air gaps, the air gap here is meant the part between flabellum upper limb 9 to first permanent magnets, 3 inner side surfaces and flabellum lower edge 10 to second permanent magnets 4 inner side surfaces, two width of air gaps should be below 0.3mm, to obtain bigger magnetic induction intensity.
The number with described flabellum 11 is identical respectively for the number of described first permanent magnet 3 and the groove 5 of second permanent magnet 4.
Wall on the described fan lid 1 is empty.
The following describes the working principle of this wind power-generation integrated machine with soft magnetic fan-leaf.When fan did not rotate, the magnetic flux in each coil 6 did not all change, and can not produce electric current in the coil 6 this moment, thereby can not produce electric energy.When fan 7 is met the wind rotation, the relative position of the coil 6 on electric fan lower edge 10 and the fan seat 2 can change with the rotation of flabellum 7, and the intersection area that all flabellum lower edges 10 project to the zone of second permanent magnet 4 and 6 regions of coil that all embed second permanent magnet 4 also experiences the reciprocal variation of the gross area that all coils 6 encloses on 0 to second permanent magnet 4.Suppose that fan 7 has 8 flabellums, then the frequency of this variation is 8 times of fan 7 rotational frequencies.Above-mentioned total magnetic flux by all coils 6 on second permanent magnet 4 is proportional to the area of intersection simultaneously, so the variance ratio of total magnetic flux is proportional to the intersection area change rate, the intersection area change rate is proportional to the rotating speed of fan 7, and by the electromagnetic induction fundamental theorem, the variance ratio of the total magnetic flux of all coils 6 is proportional to the electromotive force that produces in the coil 6 on second permanent magnet 4.So the electromotive force that produces in the coil 6 is proportional to rotation speed of the fan.Can produce alternating current in the above analysis coil 6, and the electromotive force that can obtain after all coils 6 correct serial connections on second permanent magnet 4 is 8 times that single coil 6 produces electromotive force.Flabellum upper limb 9 is also similar with the situation of the coil 6 that embeds first permanent magnet 3.It should be noted that 10 of flabellum upper limb 9 and lower edges exist several angle poor, therefore embedding the coil 6 of first permanent magnet 3 and 6 of the coils of embedding second permanent magnet 4 also should have same differential seat angle.On this basis, above-mentioned two groups of 6 of coils at the different permanent magnets of embedding also should correctly be connected in series, and the electromotive force of acquisition is 16 times that single coil 6 produces electromotive force.Utilize the circuit board rectification circuit to realize that Ac becomes direct current so that charging in order to obtain direct current.
