Embodiment

Fig. 1 is the schematic perspective view of the utility model combination type wind power generation device, and Fig. 2 is the STRUCTURE DECOMPOSITION schematic representation of the utility model combination type wind power generation device, and the combination type wind power generation device in the utility model comprises:

Base 1, the bottom is provided with exhaust outlet 10 for open shape and in the top, is provided with most wind inlets 11 in bottom peripheral edge;

Body 2, end are connected in exhaust outlet 10 places of base 1, or one-body molded by these base 1 exhaust outlet 10 places;

At least one lift-type fan blade structure 3, it is located in the body 2, and its windward side and the suitable angle of intersection of body 2 to fix;

At least one resistance type fan blade structure 4 is installed in this body 2 upper ends;

Around resistance type fan blade structure 4, locate to be provided with most can interlock first guide plate, 40, the first guide plates, the 40 additional power mechanisms that are provided with its interlock reversing switch angle of control;

Above-mentioned resistance type fan blade structure 4 and lift-type fan blade structure 3 are able to that vertical shaft 5 connects and connect with the generator 6,7 of bottom respectively;

Fig. 3 is a combined planar schematic representation of the present utility model.

Therefore, the utility model can be installed on and wait the flow-disturbing serious area in the urban district, as shown in Figure 5, can be installed on general iron sheet taper roof 8, or place roof, general cement plane 9 as shown in Figure 6, introducing wind is imported by base open position, 1 bottom and wind inlet 11 thereof, for guides wind to flowing, subtract to press down and introduce the sinuous flow that wind produces, confining space can be provided with most second guide plates 12 (with reference to Fig. 1 in this base 1, Fig. 2 and Fig. 4), lay in an end closing of second guide plate 12 and with suitable angle, therefore, by the guiding effect that second guide plate 12 is provided, make and introduce wind by base 1 bottom and wind inlet thereof 11 and be subjected to the guiding of second guide plate 12 and can stablize and upwards flow, reach current stabilization and collect the effect of wind; Simultaneously,, make wind speed accelerate, can reduce the startup wind speed because body 2 formed throats reach white effort law effect physically.

Then, guiding introducing wind upwards is earlier by lift-type fan blade structure 3 in the body 2, because this lift-type fan blade structure 3 intersects with fixing suitable angle and this body 2, for example 90 °, therefore, need not fully to chase after wind move can remain in down with the wind to, so, make structure become simply, effectively reduce costs such as installing and maintenance, improve generating efficiency.

And institute's installation position is subjected to the rising hot-fluid of exposure in sunshine generation and indoor generation, also can upwards flow via guiding of the present utility model, and on high stack effect acceleration introducing wind direction, flow, more can further reduce the startup wind speed, simultaneously with roof and room temperature lowering.

And resistance type fan blade structure 4 locates to be provided with most first guide plates 40 on every side, the may command water conservancy diversion is introduced wind, can make introducing wind all blow to the partial Upwind face of blade, and stop and introduce the wind air blade back side of supporting or opposing, thereby eliminate known resistance type wind generating unit because of facining the wind and leeward blade while brake effect that wind-engaging produced.

On the other hand, the introducing wind (containing hot-fluid) of being guided by body 2 then can be assisted and be promoted resistance type fan blade structure 4 blades.

In addition, the utility model can be complied with required increase lift-type fan blade structure 3 plural serial stages (consulting Fig. 7), or increases resistance type fan blade structure 4 length of blade, makes to improve generated energy.

And first guide plate 40 more can protect and prevents that bird from hitting (Bird killer) and causing structural damage; Also can close fully and make the effect of protection is provided when high wind such as typhoon produce.

And in the reality, also visual budget or demand are only installed lift-type fan blade structure 3 or resistance type fan blade structure 4.

Put in order above-mentionedly, the utlity model has characteristics as described below:

(1) need not to chase after wind and rotate down with the wind, structure is relatively significantly simplified, and is with low cost, and the wind power utilization rate is preferable.

(2) be fit to be installed in flow-disturbing such as city and seriously reach the unstable place of wind direction.

(3) being provided with first guide plate can effectively reduce flow-disturbing, raises the efficiency.

(4) first guide plates can the controlled rotation angle, prevents situations such as high wind or bird hit.

(5) in conjunction with the advantage of lift-type and resistance type wind generating unit, it is low to start wind speed, and operating range is big.

(6) can or increase resistance type fan blade structure blade length according to required increase lift-type fan blade structure plural serial stage, improve generated energy.

(7) be provided with body and form throat and reach physically white effort law effect, make wind speed accelerate, can reduce the startup wind speed.

(8) infield can be guided by Exposure to Sunlight or room temperature, utilizes high stack effect to quicken to introduce on the wind direction and flows, and reduces and starts wind speed, simultaneously with roof and room temperature lowering.

(9) bearing load of vertical shaft is lighter than the bearing load of horizontal axis, and because of the aperiodicity load, bearing life is longer, reduces maintenance cost.

(10) vertical shaft can directly be linked in the bottom generator, the power conversions designs simplification, and maintenance cost reduces.

(11) can install small-sized electric generating apparatus respectively, and can not check and balance, it is low to start torsion, and operating range is wide.
