Embodiment
See also Fig. 1 to Fig. 4, be the selected example structure of the present invention shown in the figure.
The wind generating unit of present embodiment, as shown in Figure 1, it comprises: a body 1 is to be gradually-reducing shape by the bottom to the top, in the present embodiment, the bottom of this body 1 inboard has a large-diameter portion 11, and the top has a minor diameter part 12, produce acceleration to utilize this large-diameter portion 11 with minor diameter part 12, and this body 1 bottom periphery has the intake grill 13 that communicates with the inboard more than, this body 1 top has an exhaust outlet 14, and these exhaust outlet 14 1 sides are provided with a generator set 2.In the present embodiment, this generator set 2 has a wheel hub 21, several flabellums 22 and a generator 24, and this wheel hub 21 is to link to each other by a transmission shaft 23 with flabellum 22, with by the rotation of this wheel hub 21 with flabellum 22, so that this generator 24 carries out wind-power electricity generation.
The principle of the present invention's utilization is to utilize the body 1 of this area convergent to make the gas on ground enter this body 1 inside, because this body 1 is a gradually-reducing shape, can form the effect of venturi principle, thereby can learn that gas can produce acceleration in body 1, the higher then high air pressure of height that adds this body 1 little principle that heals, and utilize high altitude stream body 1 top of flowing through to form wind at the mouth of pipe and cut effect, make this body 1 top form a negative pressure state, i.e. the effect that air-flow in the body 1 is produced Bernoulli.Because atmospheric pressure is littler with past more high altitude pressure, but its pressure is still evenly gradually little pattern, when the pressure at exhaust outlet 14 places during less than herein average atmospheric pressure, be negative pressure, and the air of body 1 bottom promptly can upwards fill vacancies in the proper order remedying the deficiency of pressure herein, and the air in the body 1 can up be taken out.Via above-mentioned process, more aggravate the speed of air-flow in the body 1, so that gas in this body 1 is ejected, the air-flow kinetic energy that quickens to be produced comes the flabellum 22 of pushing generator 2 whereby, by the energy of these flabellum 22 rotations, in order to drive this generator 24, to obtain more stable wind-power electricity generation.
Secondly, to be wind enter from the intake grill 13 of body 1 bottom operation situation of the present invention, because the sectional area of this large-diameter portion 11 is greater than the sectional area of minor diameter part 12, when air-flow just forms a Venturi tube by large-diameter portion 11 through minor diameter part 12, can make air-flow generation hastening phenomenon in the body 1, simultaneously, this body 1 top is because of the generation of negative pressure, the speed of updraft in the body 1 is faster with making again, the kinetic energy that utilizes air-flow to quicken to be produced comes the flabellum 22 of pushing generator group 2, by the energy of these flabellum 22 rotations, in order to drive this generator 24, to obtain more stable wind-power electricity generation.
Moreover, because this generator 24 is to be located at body 1 top, make the noise that this generator 24 produces, because of the propagation of source of sound is upwards to propagate, so, will reduce the noise pollution of surrounding resident greatly.
In sum, the present invention utilizes simple member, and it is preferable and significantly reduce the wind generating unit of noise pollution that design has stability, and it is low and advantage easily is set to have fabricating cost concurrently.
Certainly, still there are many examples in the present invention, therebetween the only variation on the details.See also Fig. 2, it is the second embodiment of the present invention, and wherein, these body 3 inside are provided with some lugs 31 that are provided with in opposite directions that are, and the sectional area that will make these body 3 inside that is provided with of this lug 31 from bottom to top is the state of convergent, so, can allow every promptly the generation once of air-flow of body 3 inside quicken, and every acceleration kinetic energy that one time air-flow had is just bigger through a lug 31, relatively, the generated energy that is produced also just the more, whereby, also can have stable generated energy.
See also Fig. 3, it is the third embodiment of the present invention, wherein, below these body 4 top exhaust outlets 43, be provided with a containing space 41, ccontaining for this generator 42, so, the kinetic energy that can make air-flows in this body 4 is the flabellum 42 in order to promote this generator all, to produce the generated energy of maximum.
In addition, as shown in Figure 4, it is the fourth embodiment of the present invention, wherein, more can establish a diversion division 51, so that the air-flow that enters from intake grill 52 can be because of the water conservancy diversion of this diversion division 51 in these body 5 inner bottom, and can not produce turbulent flow, make this air-flow have preferable kinetic energy.
