Embodiment
As shown in Figure 1, vertical axis windmill of the present invention comprises main rotating shaft 1, upper supporting piece 2, driving machine 3, lower support element 4, lower support element annex 5, transmission device 6 and fixed base 7.Main rotating shaft 1 is rigidly connected with upper supporting piece 2 and lower support element 4, and upper supporting piece 2 Cross section Design is streamlined, and lower support element 4 is disc; At lower support element 4 periphery, two or more lower support element annex 5 is installed, is distributed on main rotating shaft 1 around, and the cross section of lower support element annex 5 is also designed to streamlined; Driving machine 3 is arranged between upper supporting piece 2 and lower support element 4, is distributed on around main rotating shaft 1, and driving machine 3 running shaft bottom is through lower support element 4.As shown in Figure 2, transmission device 6 comprises center fast pulley 601, drive wheel 602, driving wheel 603 and outer cover 604.Center fast pulley 601 is arranged in fixed base 7 and maintains static; Drive wheel 602 is arranged on lower support element 4; Driving wheel 603 is arranged on the running shaft lower end of driving machine 3; Drive wheel 602 is positioned in the middle of center fast pulley 601 and driving wheel 603, and three is at same level internal messing; Driving wheel 603 rotates together with driving machine 3, drive wheel 602 is driven to rotate, and rotate around center fast pulley 601 together with drive wheel 602, driving machine 3 is revolved round the sun again while rotation, rotates around main rotating shaft 1 axis together with main rotating shaft 1 with upper supporting piece 2, lower support element 4 and lower support element annex 5.Outer cover 604 is arranged on below center fast pulley 601, enters transmission device 6 to prevent foreign material.
Now in gear-driven mode, working principle of the present invention is described:
As shown in fig. 1, under certain wind-force effect, driving machine 3 can be rotated counterclockwise around own axes, therefore in fig. 2, driving wheel 603 is also rotated counterclockwise under driving machine 3 drives, the drive wheel 602 engaged with driving wheel 603 can turn clockwise around own axes, because the center fast pulley 601 engaged with drive wheel 602 maintains static, namely revolves round the sun so driving wheel 603 and drive wheel 602 Hui Rao center fast pulley 601 while rotation turns clockwise.Because driving wheel 603 is arranged on driving machine 3 axle head, driving machine 3 is arranged between upper supporting piece 2 and lower support element 4, upper supporting piece 2 and lower support element 4 are rigidly connected with main rotating shaft 1 again, so the revolution of driving machine 3 achieves the rotation driving main rotating shaft 1, blower fan starts to start.Along with the startup of blower fan, revolution speed can make the relative speed of wind blowing to driving machine 3 strengthen, the moment of torsion of its rotation and speed just can strengthen thereupon, and the moment of torsion that the increasing of the moment of torsion of rotation and speed can make wind energy conversion system revolve round the sun and speed strengthen ... thus whole wind energy conversion system rotating speed will strengthen gradually, until reach working speed and start working.
Transmission device 6 of the present invention can select gear transmission or other kind of drive such as pulley drive, silent chain transmission according to product actual demand, namely the transmission between center fast pulley 601 and driving wheel 603 can not limit by the kind of drive, the revolution contrary with its rotation rotation direction is done, to drive the rotation of main rotating shaft 1 while still making driving wheel 603 rotation.
Form and the quantity of the shaft resistance type windmill of the driving machine 3 in vertical axis windmill of the present invention can be determined according to actual needs.
In vertical axis windmill of the present invention, the material of all parts and size are all determined according to the technical requirements of product.
