Abstract

A wind motor with a rotor with vertical axis of rotation is described. The blades (02) have axles parallel to the vertical axis of the rotor. The axles of the blades (02) are pivotably mounted between an upper and a lower plate of the rotor. Both, the axles of the blades and the vertical axis of the rotor carry pinions or pulleys (05, 08). These pinions or pulleys (05, 08) are positioned above the upper plate of the rotor. The synchronized, cyclic movement of the blades (02) relative to the rotor of the wind motor is achieved by driving belts (06) connecting pinions or pulleys (05, 08) mounted on the axles of the blades (02) and on vertical axis of the rotor, respectively.

Description

WIND MOTOR WITH SYNCHRONIZED, CYCLIC MOVEMENT OF THE BLADES RELATIVE TO THE ROTOR
The present invention is referred to as the wind-powered rotor generator and multiple vertical paddles with synchronized turn between rotor and paddles.
Generators of horizontal and vertical rotation axle that consist of a revolving rotor activated by an "x" number of paddles according to the manufacturer's design are known, which are united by one of the ends to the rotor axle or by the two ends as in the case of the ones of vertical axle.
The before mentioned generators that are in use, are not efficient since the energy that they extract from the air is a low percentage with respect to the horizontal drive force of the wind, every time that this one stresses in a diagonal way on the blades, by the design of the same and also for each complete rotation of the axle, the blades offer a certain level of resistance when its upper surface remains exposed in the direction of the wind, which causes loss of output.
In generators in use, the sum of the blades area exposed in any point of the axle rotation represents a very low percentage with respect to the total area of rotation exposed to the wind drive.
In giant aerogenerators for several hundreds of kilowatts or several megawatts, actually in use their manufacture and assembly costs are excessive for its own design, since the carry-all where the generator is installed, forces the tower to be more resistant and the assembly of the same carry-all, because of its weight and size, demands a special equipment for this.
The purpose of the following invention is to avoid the problems of the before mentioned models, taking the maximum advantage of the horizontal drive of the wind and reducing the investment costs in manufacture and assembly.
The peculiarities of this invention are original and unique, and it solve the before mentioned problems with a series of advantages that we will describe further on.
The wind-driven generator of axle and vertical paddles with synchronized turn between rotor and paddles, object of the present invention, characterizes itself by the fact that the rotor is a cylindrical body with two circular tops, the ones which give it the shape of a roll, which rotates over a central axle, in its basic model that can be good to generate energy in the rank of some tens of kilowatts figure 1.
Figure 2, is a front elevation, in which we can appreciate the fundamental parts of this invention that are:
01. Axle of the rotor.
02. Synchronous pinion or pulley of paddle axle. 03. Synchronous chain belt or band or transmission.
04. Synchronous pinion or pulley of rotor axle.
05. Chain turnbuckle or synchronous band of transmission. 06. Axle of paddle.
07. Cylindrical body of the rotor. 08. Upper top of the rotor.
09. Lower top of the rotor. 10. Paddle.
11. Synchronous pinion or pulley mounted in the exterior part of the lower top of the rotor for transmission of the kinetic energy.
12. Base column.
13. Helicoidal ring gear for orientation of paddles regarding the wind.
14. Worm gear for activation of the helicoidal ring gear.
15. Base.
The paddles are in the shape of a rectangular prism and a longitudinal axle that rotates over two bearings of balls or rollers, situated one in each top of the rotor. In figure 3 we can appreciate: 01. Paddle axle.
02 Synchronous pinion or pulley of the paddles axle. 03 Upper top of the rotor. 04 Bearing. 05 Paddle. 06 Lower top of the rotor. 07 Bearing.
The synchronous rotation of the paddles on its own axle with respect to the rotation of the rotor on its axle, is obtained thanks to the transmission that is an exclusive design of this invention and consists in that the axle of the paddles juts out by the upper top of the rotor and has a synchronous pinion or pulley in its end, at the same time in the central axle of the rotor there are stationary synchronous pinions or pulleys in correspondence with the ones of the paddles, being the synchronous pinions or pulleys situated in the axle of the paddles two fold in diameter to the one of the central axle of the rotor, being obtained in this way that when the rotor makes a complete rotation over its axle, the paddles make one half rotation on its own axle; which allows that the 50% of the paddles to present an broad are of resistance to the horizontal drive of the wind, taking advantage of it by means of a leverage effect and the other 50% of the paddles its exposed are is the minimum one. In figure 4 the view in plant with the following elements can be appreciated:
01. Upper top of the rotor.
02 Paddle. 03 Virtual angle between two consecutive paddles. 04 Turnbuckle of the chain belt or synchronous band. 05 Synchronous pinion or pulley of paddle axle. 06 Chain belt of synchronous band. 07 Axle of the rotor. 08 Synchronous pinion or pulley of the rotor axle.
The orientation regarding to the wind is obtained by means of a rotation motion toward the right or the left whichever may be the case of the rotor central axle with its stationary pinions and likewise the velocity or braking can be regulated. Figure 5 shows an example of how this mechanism can be implemented with the following elements:
01. Worm gear.
02. Base column of the generator. 03. Helicoidal ring gear.
04. Rollers bearing.
05. Base.
06. Rollers bearing of angular contact.
For models of big capacity it is required to avoid that the paddles will bend because of the effect of the wind, which is achieved by means of interposed supports for the paddles axle as an example can be observed in figure 6 which shows us: 01. Bearing.
02 Upper top of the rotor. 03 Paddle section. 04 Central top of the rotor. 05 Paddle section. 06 Lower top of the rotor. 07 Base column of the generator.
The reduction of costs in the towers is obtained thanks to that tensor agents can be installed from the ground to a nearby ring to the base of the rotor rotation to counteract the effect of the wind drive on the whole, as it can be appreciated with an example in figure 7, figure 1 shows a view in 3D of a wind powered generator of vertical rotor and paddles with synchronized turn between the rotor and the paddles.
Figure 2 shows a front view, in which one of the ways to give motion to stationary pinions of the rotor axle is considered, pivoting the axle in the base and using a helicoidal ring hear with a worm gear activates by a servo controlled by the paddle of directional orientation.
Figure 3 shows a superior view where the transmission between the stationary pinions of the rotor and the ones of the paddles is observed, which are symmetrically regarding the rotor axle.
Figure 4 shows a cut of the front figure at the height of the central axle of the generator, where one of the alternatives that this invention offers for its manufacture can be observed.
Figure 5 is a transversal cut where an alternative to orient the generator regarding to the wind is appreciated.
Figure 6 shows us the way of how interposed supports to a paddle can be given, by means of interposed tops of the rotor.
Mentioning figure 1, the wind-driven generator, of vertical axle, consists of a cylindrical rotation rotor with two tops roller shaped, activated by six rectangular paddles, over which the wind exercises its horizontal pressure and this one is transmitted to the rotor through its tops by means of a leverage effect.
Paddles are distributed in a radial way and equidistant to the rotor axle, being the width of these such that will allow its rotation on its central axle without colliding with the central body of the rotor.
The synchronous pinions or pulleys are situated in the external part of the upper part of the rotor directly over the axle of each paddle allowing its direct activation.
The central synchronous pinions or pulleys for the activation of each paddle are also situated in the external part of the upper top of the rotor, mounted over the central axle of the rotor, corresponding to it a synchronous pinion or pulley for each one to the paddles.
The force for the activation of the paddles rotation is obtained by means of the chain belt or synchronous band, between the central synchronous pinions or pulleys and the synchronous pinion or pulley of each paddle.
The constant tension in the chain belt or the synchronous band is obtained by means of a turnbuckle for belt chain or synchronous band, situated between the central synchronous pinion or pulley and its corresponding in the axles of the paddles, fixed over the upper top of the rotor.
The interior value of the virtual angles that are generated between two subsequent paddles will be of 30° speaking about the present model described in the figure of six paddles.
Being the present invention a wind-driven generator of rotor and vertical multiple and variable paddles in its number, the value of the virtual angles that are generated in each model will depend of the number of paddles with which the wind-driven generator will be manufactured, being while bigger the number of paddles; smaller the value of the value of the virtual angle, and the smaller the number of paddles; the bigger the value of the virtual angle, but always equal between them in each model and being the sum of all these angles in each model 180°.
The wind-driven generator of rotor and vertical multiple paddles, can be sued to generate an electrical generator, a transmission system for mills, pumps or any other type of equipment that will require an external propeller source.
