Abstract

The invention relates to an energy collection pipe transferring wind energy generator that belongs to wind collection ultra-large wind power generating device. It has at least one bugle-shaped wind collection mouth connecting wind guiding pipe that connect to the sealed machine room and the entrance is aiming at the wind energy generator driving structure or the generator impeller. A chimney type suction ventilation pipe extending to upward is set on the top of the sealed machine room. The invention could omnidirectionally suck wind power and expand the acreage of wind collecting. And the wind energy wasted in wind guiding pipe is low, so the generator works steadily.

Description

Energy collection type wind energy power station by pipe conveying

Technical field:

The present invention relates to a kind of collective wind type vast capacity wind generating unit.

Background technique:

Existing wind power station has utilized the windmill type principle, and efficient is low, and very limited also being difficult to of single generator for electricity generation capacity improves, because generator will be installed in above the high pedestal.Increase generate output and will strengthen the leaf blade diameter, increase the generator number, thereby fitting limit scatters.Thereby equipment investment height, and maintenance cost height, reliability is low, the power cost height of production.

Summary of the invention:

The objective of the invention is to overcome above deficiency and a kind of receiving area that adds strong wind is provided, but high jumbo generator set is installed in the flow velocity concentration point of accelerating wind, can improve the generating kilowatt of wind-driven generator exponentially/time number, and energy collection type wind energy power station by pipe conveying simple in structure, with low cost.

The present invention is achieved by the following technical solution: this energy collection type wind energy power station by pipe conveying, its major technique feature is its collection air port connection guide duct by one or more horn, guide duct feeds in the machine room of sealed type, generator impeller or the wind-driven generator driving mechanism that is located in the machine room aimed in outlet, and the machine room top of sealed type also is provided with upwardly extending funnel-shaped suction ventilation duct; Wind-driven generator driving mechanism that described each guide duct inserts in the machine room respectively or machine room is outer or the combination of the guide duct more than two back become total guide duct to insert in the generator machine room again or the outer wind-driven generator driving mechanism of machine room; Be provided with pressure valve at bell-mouthed end or guide duct, total guide duct; Described iiared port place is provided with the grid net of anti-foreign material, and the area of grid net is equal to or greater than bell-mouthed area, the grid net be connected up and down or symmetrical rotating shaft on; Described suction ventilation duct end face suitable for reading is that plane or outer ledge are angle or arc shape face; The lower end is communicated with top, side or the bottom of Generators; Wind-driven generator driving mechanism outside machine room is a sealed type, and inlet connects guide duct, and the outlet port is inserted in the machine room or inhaled ventilation duct; Described suction ventilation duct end face outer ledge suitable for reading be angle or arc shaped surface to around extension.

The present invention adopts that horn mouth is collected folk songs, the form of pipeline transmission wind and the sealing of generator machine room, enables comprehensive absorption air quantity, has increased wind and has collected area, reduced the wind energy loss; Utilize again and inhale ventilation duct, when process was inhaled the ventilation duct exit end face when altitude air was flowed, non-current air forms a pressure difference in the moving air in the pipeline external world and the pipeline, and the air-flow that flows through that makes suitable for reading of arc surfaced forms one to the flow curve of appearing on the stage above pipe outlet; Simultaneously again because the formed pressure difference of highpressure in the generator machine room of the lowpressure in high-altitude and lower end of duct sealing, under the effect of the two, accelerate to inhale the ventilation duct air-flow velocity, produce powerful attraction force simultaneously, cause the air-flow in the guide duct to quicken, the wind energy loss reduces, so the generator working stability, thereby realizes producing with less energy consumption the effect of more electric energy.

Embodiment:

As shown in Figure 1, this wind energy power plant is with a plurality of horn mouths 1 or form horn mouth battle array collection wind energy, horn mouth is installed on the different direction of various places, each horn mouth is connected with guide duct 2 respectively, guide duct can directly feed generator machine room 3, also the several branch guide duct in same direction or same place can be aggregated into total guide duct 2 ', feed the machine room of generator 5 again, wind energy is merged into more powerful energy, the guide duct outlet is pressed the direction of generator impeller 4 rotations and is arranged (Fig. 2), and aligning generator impeller, impeller links to each other with alternator shaft 6, when the wind energy of being collected from all directions by horn mouth is sent to generator set and during to impeller action through guide duct, generator impeller rotation, impeller drive engine shaft rotation, generator work.Simultaneously, the no wind energy collection of working as a certain direction or a certain place for assurance is fashionable, the wind energy of guide duct that other horn mouth is sent into can not flow backwards, at every or every group of bell-mouthed main entrance place's installation automatic pressure valve 8, the blast of sending in situation and the guide duct according to wind-force opens and closes automatically valve, and the assurance wind energy is not lost.

For the loss that the collected wind energy of horn mouth is transmitted in guide duct is reduced, the generator machine room of this device is totally enclosed, the machine room upward opening extends tens of to the high suction ventilation duct 7 of hundreds of rice, its principle is that altitude air flow to when inhaling the ventilation duct exit end face, noncurrent air forms a pressure difference (aufbauprinciple of sprayer) in the moving air in the pipeline external world and the pipeline, simultaneously again because the formed pressure difference of highpressure (chimney principle) in the Generators of the lowpressure in high-altitude and lower end of duct sealing, under the effect of the two, the air-flow of inhaling in the ventilation duct upwards flows rapidly, it is high more to inhale ventilation duct, and the air velocity of inhaling in the ventilation duct is just big more.Because of inhaling the ventilation duct lower end is to link to each other with the generator machine room, the generator machine room seals again, if there is not guide duct to be connected with it, this airflow flowing will make the air pressure decline of machine room inner room develop to the vacuum direction, just because of extending, the outlet of guide duct is installed in the machine room, so the vacuum efficacy that air-flow produced in the ventilation duct produces powerful attraction force to the air-flow of introducing in the guide duct.Make the air-flow in the guide duct quicken to reach the purpose that reduces transmission loss,, the existence of air flow is arranged still in the guide duct, inhale ventilation duct simultaneously and play the effect of draining and ventilating again even under the calm situation in ground.

As shown in Figure 4, be blown into horn mouth for preventing the effect of foreign material wind-engaging power, be provided with the grid net of preventing foreign material at horn mouth, the grid net can be rotated with rotating shaft 9-1,9-2 by driven by motor, and the area of grid net is equal to or greater than the area of flared horn.

As shown in Figure 3, inhale ventilation duct 7 end face outer ledges suitable for reading and be angle 7 ' and arc shape 7 "; when making high altitude stream; air flow direction upwards lifts along this angle and arc shape and forms the curve ripple; the air-flow of inhaling in the ventilation duct is played the effect that drainage is quickened through this angle face, angle towards around extend.
