Abstract

The utility model relates to a wind power generator, which comprises a cover body, a front nose cone, a back nose cone and a blade unit, wherein the cover body is provided with a flow guiding part with an arc surface. The front nose cone and the back nose cone are provided with a plurality of supporting posts respectively and fixedly connected with front and back sections of the inner wall of the cover body. The blade unit is arranged between the front nose cone and the back nose cone. After wind enters through a path formed between the arc surface of the front nose cone and the front section of the flow guiding part of the arc surface of the cover body, wind speed is accelerated by the contraction of the flow channel and large kinetic energy is generated to drive the blade unit to rotate to enable the generator in the back nose cone to obtain large electric generating capacity. The generator can be started when the outside wind speed is low.

Description

Wind generating unit

Technical field

The utility model relates to a kind of wind generating unit, relates in particular to a kind of multiple-blade design, can strengthen effective wind-exposuring area, and bigger drive is arranged, and produces the wind generating unit of bigger generated energy.

Background technique

Generally known " wind generating unit " is used for obtaining the wind energy of wind, and this wind energy is converted to can be for the electric energy that utilizes, and it includes: pedestal; Uprightly be arranged on the structural framing on this pedestal; A plurality of dividing plates that are arranged in this structural framing, this dividing plate and this structural framing complement each other to form a plurality of collection wind compartments that are the arrangement of lattice nido, and each collection wind compartment has the mouth that facings the wind that air feed flows inflow, and the leeward mouth of air feed stream outflow; And a plurality of fan wheel that are subjected to, these a plurality of fan wheel that are subjected to are arranged on respectively in these a plurality of collection wind compartments accordingly, each is subjected to fan wheel to include wheel hub and a plurality of air blade that is subjected to that is arranged on this wheel hub side face radially, these are a plurality of be subjected to air blade can be flowed into the distinguished and admirable promotion in the corresponding collection wind compartment, to obtain the wind energy in the wind and to be converted wind energy to mechanical energy; With these a plurality of generator units that be connected by fan wheel, can accept this a plurality of mechanical energy that transmitted by fan wheel, produce electric energy to drive.

Though above-mentioned known " wind generating unit " can utilize a plurality of fan wheel to connect generator unit and produce electric energy to drive, in use, being somebody's turn to do " wind generating unit " utilizes the mouth down with the wind of collection wind compartment and leeward mouth that wind is advanced, go out, to drive the wind-engaging blade rotation of fan wheel, but owing to be somebody's turn to do a plurality of collection wind compartments that are the arrangement of lattice nido that the pedestal of " wind generating unit " only cooperates a plurality of dividing plates to form with structural framing, and the formed collection wind of these a plurality of dividing plates compartment only is the tabular of plane all around, therefore, when wind fashionable, collect the wind compartment in smooth-going mode by each, (more then rotating speed is very fast for wind-force in the power of wind-force to make this be subjected to the limited in rotation of air blade, the more weak then rotating speed of wind-force is slower), make and respectively collect the effect that the wind compartment can't form compression wind-force, can't when more weak wind-force, obtain stronger blast, cause to power with stable speed rotation by air blade; Moreover, because the overall structure and the volume of this fan wheel are all comparatively huge, therefore, the air blade that is subjected to of this fan wheel must have the wind speed of certain intensity to be driven, if this wind speed then can cause when more weak and can't drive this and be subjected to air blade, or make this wind-engaging blade rotation slow, and cause this " wind generating unit " can't normally stable power supply.

The model utility content

Main purpose of the present utility model is to solve the defective that exists in the above-mentioned prior art.The utility model redesigns wind generating unit, allows wind generating unit have mutliblade design, strengthens effective wind-exposuring area, and bigger drive is arranged, and produces bigger generated energy.

To achieve these goals, the utility model provides a kind of wind generating unit, comprising: cover body, preceding nose cone, back nose cone and blade unit.Have the cambered surface diversion division in the cover body, above-mentioned cambered surface diversion division forms the cover body two ends and is the enlarging shape, and the gas flow of central convergent.Preceding nose cone has arcuate surface, has a plurality of pillars that are connected with the cover body inwall on the above-mentioned arcuate surface, and nose cone forms corresponding setting with cambered surface diversion division leading portion before making.Back nose cone has arcuate surface, has a plurality of pillars that are connected with the cover body inwall on the above-mentioned arcuate surface, makes the back nose cone form corresponding setting with cambered surface diversion division back segment.In addition, blade unit is arranged between the forward and backward nose cone.

In wind generating unit of the present utility model, after the passage that forms between the cambered surface diversion division leading portion of wind by the arcuate surface of this preceding nose cone and cover body enters, wind speed is accelerated, produce bigger kinetic energy and drive this blade unit rotation, make the generator in this back nose cone obtain bigger generating capacity, and can be under lower extraneous wind speed starter-generator.

Embodiment

Relevant technology contents of the present utility model and detailed description, existing conjunction with figs. is described as follows:

Fig. 1 and Fig. 2 are respectively stereo appearance figure of the present utility model and of the present utility modelly analyse and observe phase diagram.As shown in Figures 1 and 2, the utility model provides a kind of wind generating unit, it comprises cover body 1, preceding nose cone 2, back nose cone 3 and blade unit 4, can make the cover body 1 forward and backward

nose cone

2,3 of cooperation and increase effective wind-exposuring area, when air-flow during through the runner that shrinks, produce the effect of quickening, kinetic energy is increased, blade unit 4 is produced bigger kinetic energy, obtain bigger generating capacity.

Have cambered surface diversion division 14 in the cover body 1, cambered surface diversion division 14 allows cover body 1 two ends be the gas flow 13 of

enlarging shape

11,12 and central convergent.Cover body 1 comprises the multi-disc plate body, and each plate body can utilize any mode of welding, pivotally connected, snapping or the bending of single plate body to form, and has the cover body of polygonal body with formation, and perhaps cover body 1 also can be circle; Cambered surface diversion division 14 is made of lightweight material, and is made as any material of foaming material, Poly Foam, glass fibre or carbon fiber etc.
