Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also Fig. 2, shown in Figure 3, vertical shaft type wind-driven generator 20 of the present utility model comprises a wind wheel 21, the wind wheel 21 outer wind collecting section parts 22 that also are provided with, this wind collecting section part 22 comprises the swivel mount that can rotate freely and is used to collect the air gathering plate 221a that facings the wind, swivel mount is sheathed on outside the wind wheel 21, two air gathering plates 221 are arcuate structure, and are located at wind wheel 21 both sides respectively, and are located within the swivel mount.The rear side of left air gathering plate 221 also is provided with a break-in air gathering plate 221a who is used to change wind direction in Fig. 3, this break-in air gathering plate 221a also is an arcuate structure, and also be located within the swivel mount, the windward side of above-mentioned air gathering plate 221 and break-in air gathering plate 221a is its arc inner concave.This swivel mount comprises a center drum frame 222 and three collection wind framves 223, and cylinder frame 222 adopts structure steel fabrications, and fixed cover is located at outside the wind wheel 21, upwards has chute 224 in the footpath of cylinder frame 222; Collection wind frame 223 also is a steel structure frame, and its shape is suitable with the shape of air gathering plate 221 and break-in air gathering plate 221a respectively, air gathering plate 221 and break-in air gathering plate 221a can be located in it respectively, and coupled fixing.On the medial extremity of collection wind frame 223, be equipped with pulley 225, and be located in the chute 224 by pulley 225, and the two ends up and down in the outside of three collection wind framves 223 are all welded mutually by reinforcing bar connecting rod 228 and are fixed into one, can rotate freely around center drum frame 222 together.Need to prove that at this radian of this break-in air gathering plate 221a is greater than the radian of other two air gathering plates 221, the radian of two air gathering plates 221 is less.Please in conjunction with shown in Figure 4; on the air gathering plate 221 on right side and a break-in air gathering plate 221a, also be equipped with a switching that is used for ventilative protection and close parts; it is to constitute by following form that parts are closed in this switching; with this air gathering plate 221 is example; place, right side at air gathering plate 221 vertically is provided with a rotating shaft 226; rotating shaft 226 two ends are connected with collection wind frame 223 respectively; and whole air gathering plate 221 is divided into two parts; left side 2/3 part is for fixing; and right side 1/3 part can be carried out deflection along rotating shaft in collection wind frame 223; when normal condition; it is closed state that parts are closed in this switching; whole air gathering plate 221 all carries out wind collection wind; and when running into strong wind or storm wind, switching is closed parts and is opened automatically, i.e. air gathering plate 221 right sides 1/3 part deflection several angle; certain air quantity is seen through from this, thereby can avoid making air gathering plate 221 because of wind-force is excessive; break-in air gathering plate 221a and fan blade are impaired.This wind collecting section part 22 also comprises a tail plate 227, and tail plate 227 is located at the rear side of center drum frame 222, and collects wind frame 223 accordingly by reinforcing bar connecting rod 228 and its both sides and weld mutually and be fixed into one, can be rotated with collection wind frame 223.
Please consult shown in Figure 3 again, during use, this generator 20 can drive fixing air gathering plate 221 by swivel mount and rotate freely, thereby the windward side of air gathering plate 221 is aimed at all the time and be the wind comes from, and concentrate wind-force by air gathering plate 221, for wind wheel 21 provides powerful effectively wind regime, thereby improved the rotating speed of wind wheel 21, the real breeze start-up of realizing has improved utilization efficiency.False wind is to shown in solid arrow among Fig. 2, wind wheel 21 is rotated counterclockwise under the effect of collection wind so, what wind wheel 21 was located to be subjected at A ' is lift, do positive work, and locate at B ', because wind-force is subjected to blocking of break-in air gathering plate 221a, reduced resistance that this place's fan blade is rotated counterclockwise greatly, and making the wind comes from concentrates and turns to (dotted arrow among Fig. 2 promptly is shown and makes about) along the arc windward side of this break-in air gathering plate 221a, the fan blade that C ' is located provides lift, thereby make C ' locate fan blade and also do positive work, improve the output power of this generator 20 greatly.
Vertical shaft type wind-driven generator 20 of the present utility model compared with prior art, required startup wind speed reduces greatly, only need the startup wind speed of 1.5m/s just can generate electricity, and under same output power prerequisite, wind wheel 11 diameters of Da Lie H type wind-driven generator 10 are 4～6 times of wind wheel 21 diameters of this generator 20, thereby greatly reducing overall cost, effect is fairly obvious.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model the above embodiment's variation, modification.
