With reference to Fig. 1-4; This embodiment is taked following technological scheme: it comprises base member case 1, flange 2, bearing 3, main shaft 4, battery pack 5, gear-box 6, negative axle 7, reduction of speed speed stabilization machine 8, filler 9, generator 10, voltage stabilizer 11, transformer 12, water outlet 13,220V input interface 14,220V output interface 15, usb 16, lighting burner 17 and luminous lamp switch 18; Base member case 1 top is provided with flange 2 and filler 9; Base member case 1 center is provided with main shaft 4, and main shaft 4 is provided with bearing 3 and reduction of speed speed stabilization machine 8, and main shaft 4 lower ends link to each other with base member case 1 interior gear-box 6; Gear-box 6 links to each other with negative axle 7 one ends; Negative axle 7 is provided with reduction of speed speed stabilization machine 8, and negative axle 7 the other ends link to each other with generator 10, and the right side set inside of base member case 1 has battery pack 5; Battery pack 5 left sides are respectively arranged with voltage stabilizer 11 and transformer 12; Base member case 1 external right top is provided with lighting burner 17 and luminous lamp switch 18, and luminous lamp switch 18 belows are provided with 220V input interface 14,220V output interface 15 and usb 16, and water outlet 13 is arranged on the lower left corner of base member case 1.

This embodiment master is designed to three connecting rods; Can reach the distance of controlling as required between blade and the rotating shaft through slideway; Connecting rod is the X type after launching, and like figure, A and B are the node that is fixed on above the blade; This node only allows the connecting rod longitudinal sliding motion, has therefore avoided will readjusting the operation of blade with respect to the rotating shaft angle after the expansion of portable wind power generating machine.E is that the portable wind power generating machine launches aperture overlapping on the back link fully, is the center with E, is designed to groove shaped with reference to the height partly of solid post in the rotating shaft; Make the extensible link cuttage in the corresponding part of solid post after closing up, can in the hole, insert a rivet during work of portable wind power generating machine, like figure; Stability when working to strengthen the portable wind power generating machine, but in the traditional design, E is fixing turning point mostly; So A, B, C, D place need to add a large amount of connection sets; And the problem that therefore unavoidably causes is stability and life-span when reducing the work of portable wind power generating machine, and C, D adopt the structure of " annular interlocks, and controls synchronously " and connecting rod CD end to be locked on the ring of being close to rotating shaft; When connecting rod is flexible; Four groups of connecting rods just can be worked simultaneously, greatly facilitate operation, and reduce since error that asynchronous operation brought to the influence of portable wind power generating machine working efficiency.

This embodiment has the rotating shaft of four slideways, is to make connecting rod flexible the significant design that is convenient for carrying.When portable wind power generating machine end-of-job; Ring C, D drive ring M, N rotation simultaneously to moving respectively up and down, and the cuttage of connecting rod E part is in rotating shaft solid post corresponding groove; Finally make blade and four groups of connecting rods be close to rotating shaft, to reach the purpose of saving big quantity space.

The rated wind speed of this embodiment is little, and generated energy is big, and environment is not had influence; Noise free during running, wind loading rating is strong, and magnetic disturbance is little; Its flabellum has the characteristics of complete symmetry, and is not only attractive in appearance, and when folding, is very easy to it is controlled to suitable shape.Simultaneously H type flabellum automatically to the characteristics of wind also saved traditional wind to wind mechanism, not only make structure simple more, be easy to safeguard, and also conveniently save worry using.

This embodiment is according to the principle of H type wind-driven generator, and the rotating speed rate of climb of wind wheel improves very fast (the moment rate of climb is fast), and its generated output rate of climb is also corresponding to accelerate, and the generating curve becomes full.Under same power, the rated wind speed of vertical axis aerogenerator is little than the existing level axis wind power generator, and its generated energy when low wind speed turns round is also bigger.This kind project organization has adopted special air principle of dynamics, the Placement of triangle vector method and the principle of directly driving type structure, make the stressed of wind wheel mainly concentrate on the wheel hub, so wind loading rating is stronger; The characteristic of this kind design also is embodied in the influence to surrounding environment, and noise free and electromagnetic interference be little during running etc., and characteristics make that novel vertical axis wind power generation machine superiority is very obvious.

This embodiment adopts aerodynamic principle, and to the wind tunnel simulation of vertical shaft rotation, blade has been selected the wing shape of aircraft for use, and when wind wheel rotated, it can not receive because of distortion and change efficient etc.; It is formed with vertical line 4-5 blade, fixes, connects the wind wheel that the connecting rod of blade is formed by the wheel hub of 4 dihedrals or 5 angular shape, drives the rare earth permanent-magnetic generator generating by wind wheel and is sent to controller and controls the electric energy that the transmission & distribution load is used.

This know-why of this embodiment is according to the air strip theory, and the tangent plane that Practical Calculation can be chosen vertically-supplying air machine running shaft carries out computation model, presses the blade actual size, and the axis of rotation distance of each blade is a N rice; Simulate pneumatic coefficient calculations with the CFD technology; Calculate principle and adopt the discrete digital method to find the solution the aerodynamic force of aerofoil section, with grid method the mobile Vorticity Distribution of reynolds' number is relatively formed under the high reynolds number N portable wind power generating machine vier-Stokes equation is carried out digital simulation calculating principle result; Adopt the principle of rare earth permanent-magnetic material generating; The wind wheel of supporting and air hole mechanics principle adopt the directly driving type structure to be rotated generating, and H type flabellum has the characteristics of complete symmetry; Not only attractive in appearance, and when folding, be very easy to it is controlled to suitable shape.Simultaneously H type flabellum automatically to the characteristics of wind also saved traditional wind to wind mechanism, not only make structure simple more, be easy to safeguard, and also conveniently save worry using.

This embodiment rotating shaft 4-3 part in midair launches the working space that closed back slip ring slides up and down, i.e. slideway fully for the portable wind power generating machine; After the design in midair of the subsidiary groove part of solid spindle can make the power cut-off of portable wind power generating machine; Inlay wherein when connecting rod is closed; Reach and shrink the purpose that rear blade is close to rotating shaft fully; Its effect is: in portable wind power generating machine when work,, no matter blade receives the irregular power that wind brought of which kind of wind scale, which kind of wind direction, and the subsidiary groove part of solid bearing can make it always keep the invariant position of connecting rod with respect to rotating shaft.
