NL8204338A - Windmill generator - has extra rotor orthogonal to main rotor and rotated into wind in specified manner - Google Patents

Abstract

The windmill has a main rotor and an additional rotor to point the main rotor into the wind. With the main rotor rotated out of the wind, the extra rotor (also rotated out of the wind) is rotated into the wind, the main rotor thus being also rotated into the wind. When this state is reached, the extra rotor is again brought into its original position w.r.t. the wind.

To clarify the invention, with reference to the drawing, an embodiment of the windmill will now be

Fig. 3 is a cross-sectional view taken on the line III-III in FIG. 2.

According to the drawing, a dewatering windmill is provided with a foundation 1 for a mill tower 2, the head 3 of which can be rotated and secured around the vertical axis of the mill. The head 3 carries the main blade wheel 4, the shaft of which is connected to the pump 6 in the usual manner via the vertical mill shaft 5. Furthermore, the head carries on its vertical axis, parallel to the mill axis, rotatable upright 7, on which the auxiliary impeller 8 is mounted. A float 9 which responds to the dewatering level 10 is connected with a lever system 11, 12 10 to a position 13, which passes below the head 3 into a tube 14 coaxially comprising the mill shaft 5, the latter being able to move via the gear 7 to rotate its vertical centerline, thus relative to the head 3 and thus relative to the main impeller 4. The auxiliary impeller wheel 8 is coupled to the top 15 of the tower 2 via another gear, such that the head is rotated about the vertical axis by rotating the auxiliary impeller wheel.

It can be seen from Fig. 2 that the mill head 3 is rotatable about the top of the mill tower 2 by means of a partly drawn thrust bearing 15. For this purpose, a double worm and worm gear transmission with worms 20, 16, 18 and worm wheels 17, 19 (see also fig. 3) is arranged, which is intended to rotate the head 3 relative to the tower 2. The worm wheel 19 and the worm 16 are keyed on a common shaft 20. The worm 18 is located on a shaft 21, which coincides with the vertical axis of the upright 7 and is provided with a spline bevel gear 22, which is driven by the auxiliary impeller wheel 8 via a bevel pinion 23. Therefore, by rotating the auxiliary impeller wheel, the head 3 and thereby the main impeller wheel 4 will be rotated about the vertical mill axis.

The main impeller 4 is keyed with its hub 24 on a shaft 25, which shaft drives the mill shaft 5 and with it the pump 6 via bevel gear 26 and bevel pinion 27.

Freely rotatable on its vertical axis, the upright 7 is mounted on a projection 30 of the head 3 by means of ball or roller bearings 28, 29, wherein a sleeve 31 situated coaxially about the axis 21 is provided with a bevel wheel 32, which cooperates with a bevel gear 33, which is keyed on one end of a shaft 34. The axes 25 and 34 are not in line with each other, but are parallel to each other in a horizontal sense 8204338 ':::?: · 4ίΙ \ ;;; Κ: · ^ | ·. I "" *.

Each end of this shaft carries a crank 35 with slotted pin 36 into which eftn kg / u ^ 37 engages / which is welded onto the sleeve 14. The float; qvmgj ^ ebfip $ fce level changes, which effect a maximum of a rotation of the grooves 9Φ | ,, | ρ up to 45 <| on either side of the horizontal position 5, are caused by axial shifting of the sleeve collar 37 under the crank 35 in a rotational movement of shaft 34, so that the conical wheels 32, 33 this movement rotate the upright and thereby the auxiliary impeller wheel with respect to the main impeller wheel. % | i || ^ rl ^ || ^ tg results.

The construction windmill is as follows. Starting from one; .cca ^ taf ^. | fjLndgicht || jqf «a water level above their desired 11 Ζ ^ fcjsfc top ^ hoopswheel in the wind and revolving, auxiliary impeller wheel is out of the wind, so below the $ mainflip wheel. If the dehydration level is now b * ftdafed, it becomes | auxiliary impeller wheel rotated with its upright, so that iMÉk.gjen encloses an oblique angle with the wind direction and starts to rotate. This turns the head with the main impeller until the auxiliary impeller is out of the wind. (The latter also takes place when the wind direction changes). As long as the main 20 impeller still encloses an oblique angle to the wind direction, the pump is pumped and the float moves vertically downwards, until the main impeller wheel is turned completely out of the wind by means of the auxiliary impeller via a gradual transition, whereby the auxiliary impeller impeller is parallel to the main impeller.

The invention has been explained above to the languages. It will be clear, however, that the invention is not limited to this, but that other applications, for example for driving a generator, are also possible.
