(5) embodiment
With reference to the accompanying drawings, the improvement of vertical-shaft wind recovering device is comprised a reinforced concrete tower 1, at cat head one ventilation body 2 is arranged, this ventilation body 2 has a side of opening wide, but its whole profile is limited by adjustable venetian blind 3.
Described improved practical embodiment shows basically according to three kinds of selections that can reach the height of tower 1 and ventilation body 2 formed structures.
First selects, and has the structure of a height between 10 and 15 meters, and specifically the place that will settle according to it and the wind-force of expectation are retrieved to determine.
Second selection is the structure of a height between 5 and 10 meters, specifically according to aforementioned identical factor.
For for example be directly installed on factory house, dwelling and even roof above the feed cistern on, the last the 3rd to select be that height is below 5 meters.
According to top description, height is included in wind speed between 5 and 21 meter per seconds (18 and 75.6 kms/hour) at the best effort layer of the style between 5 and 15 meters, can obtain significant performance.These wind regime most possibly appear at coastal area and mountain valley and plateau.
As for highly lower form, optimum performance can obtain between the wind speed of 4 to 8 meter per seconds (14.4 and 28.8 kms/hour), and a high low value appears at city and open hinterland usually.
The thin-walled 4 that the inside of above-mentioned ventilation body 2 has reinforced concrete to make, they provide all passages 5 shown in Fig. 3 to 7, make the wind that comes from the outside be directed into vertical shaft solid of rotation 6, this solid of rotation 6 preferably is positioned at the center of ventilation body 2, and such solid of rotation adopts 5,6 or 8 blades 7 usually.The specified arrangement of passage 5 makes wind energy enough tangentially act on described blade 7, therefore helps the rotation of described solid of rotation 6.Because their are near solid of rotation 6 motion, the cross section of each passage 5 constantly dwindles, and makes that the exit portion of the surface ratio passage 9 that enters zone 8 is big.Dwindling of this part forces the wind speed that reclaims in entering zone 8 to increase.These make recovery and its orientation independent of wind along the layout that enters zone 8 of ventilation body 2 peripheries.
Consider above-mentioned wind speed factor, for example should mention 15 square metres the fact that region surface 8 can reclaim about per second 60 cubic metres of air that enters, these air are forced to withdraw from through the channel outlet 9 of 4 square metres of cross sections, producing about 3.75 times sizable speed increases, make wind with one greater than 70 Kilogram-Meter Per Seconds
2(kgm/s
2) pressure act on blade 7, in case resistance of air loss is deducted, cause the rotation of solid of rotation 6 between 1.5 and 1.7 revolutions per seconds (rps).
Can notice that from Fig. 2 the bottom surface 10 of ventilation body 2 inside and end face 11 are not levels, all, its objective is the outlet of reducing passage 9, and therefore increase the wind speed that acts on blade 7 slightly towards solid of rotation zone 6 bendings.
Through the foreign body in the slit of venetian blind 3 since the bottom 3 ' of the inclination of they self weight and above-mentioned bottom surface 10 and described venetian blind 3 not exclusively sealing the fact and discharge from ventilation body 2, as illustrated in fig. 1 and 2.Low velocity wind when in addition, this specific layout can reclaim well and appear at strong blast and finish.
With an above-mentioned ventilation body 2 of umbrella shape covering 12 protections that is provided with a sharp-pointed peripheral projection 13, the purpose of doing like this is to avoid venetian blind 3 to be subjected to invasion and attack such as the outdoor objects of snow and water.Covering 12 be provided with make solar beam can be thoroughly to the transparent last center region or the cap 14 of solid of rotation 6, thereby can make blade 7 and the edge of the flat bottom 7 ' of suitably being polished warms.This warm temperature of the wind that is positioned at there that makes rises, and consequently moves towards the top of solid of rotation 6, and so automatic formation one is stated the air-flow of solid of rotation 6 from outer the facing up of device.With the method, can reduce the higher breakaway torque of vertical-shaft wind recovering device.
Solid of rotation 6 is connected in a step-up gear 15 by axle 16.Step-up gear 15 suitably oil cooled and planetary pinion, electricity and automatic class obtains one and can and carry the generator 17 of about 300 kw of power with the rated velocity rotation.Water or ethylene glycol cool off described generator 17 preferably again.In the not shown layout of another kind, various machine that step-up gear 15 is handled about agricultural, industrial plant or other society and urban applications.
All processes all can be controlled by microprocessor, preferably control by man-made satellite, thereby be provided with a series ofly be used to vibrate, such as meteorology control, speed, temperature and the hydraulic pressure of recording anemometer, aerovane and thermometer and other sensor, they control the different working condition of solid of rotation 6, axle 16, generator 17, step-up gear 15 and break basically.
This control system also can be handled adjustable shutter 3, makes them can suitably change their slit.In addition, described adjustable shutter 3 can prevent foreign body such as branch or by entering other material that causes the destruction of the blade 7 of solid of rotation 6.Make for one 18 the people can enter concrete towers 1, to carry out necessary maintenance and cleaning.
Although fully described the improved major character that is applied to the wind-force recovering device, purpose of the present invention, but it is to be noted, any change in reality is implemented, change size, non-essential shape, outward appearance and outside the modification and the material therefor type can not change (following claim is summarized) main aspect of the present invention.
