WIND TRACTION KITE SYSTEM

Wind energy, as renewable energy, is no longer to be boasted. This is the scope of the invention of the present application.

The drawbacks of conventional wind farms are also well known.

This is why, for some time, have been developing wind power generation technologies from kites which, beyond eliminating the drawbacks generated by the huge blades mounted on masts, have the advantage of the exploitation of high winds which are more regular and more constant than those which blow at the top of said masts.

From documents WO 2007/135701, WO 2008/04261 and WO 2014/087436, a wind system is known comprising at least one kite wing fixed by traction and control lines to carrier means on the ground arranged to be driven in a series of angular displacements of 360 ° under the wind action of the wing and arranged to drive an alternator shaft producing electrical energy.

The means carrying these documents are either crowns or beams that the wind, via the kite's wings, drives in rotation so as, in turn, to drive the shaft or the alternator shafts.

But such a system of the prior art also has its limits. Indeed, and it is easy to conceive, the wing exerts its traction only on a part only of the rotations, the wing having to be put in stationary on the rest of the rotations.

The invention of the present application aims to propose a system with which a kite wing exerts its traction and therefore its rotational drive almost permanently.

2017/5669

BE2017 / 5669

To this end, the invention relates to a system of the type defined above, characterized in that the carrying means are arranged so that the wing remains in charge permanently.

As the wing is almost never hovered, electrical energy is generated almost continuously.

Preferably, the carrying means are arranged so that most of their movements under the action of the wing are carried out in opposite directions along two linear sections, advantageously parallel.

In the preferred embodiment of the system of the invention, the carrier means comprise a carrier cable wound around at least two wheels mounted to rotate about a vertical axis and at least one of which is mounted on the alternator shaft.

It will be understood that the two linear sections are parallel to each other if the two wheels have the same diameter.

It will also be understood that the wing may perhaps not remain in charge during the passage, from the zone of attachment to the carrying cable of its traction and control lines, around one of the two wheels. However, since the diameter of the wheels cannot be disproportionate, it will only be an angular sector of small opening and the wing will therefore remain in charge almost permanently.

In the still preferred embodiment of the system of the invention, there is provided a plurality of kite wings attached to the carrier means.

Of course, if the system comprises at least two kite wings fixed to the support means in such a way that their respective fixing zones do not pass respectively around the two wheels at the same time, the two wings are therefore not hovered at the same time and the system remains fully charged at all times.

2017/5669

BE2017 / 5669

The invention will be better understood using the following description of the preferred embodiment of the wind system of the invention, with reference to the attached drawing, in which:

- Figure 1 is a schematic perspective view from above of the system of the invention;

- Figure 2 is a side view of the base cabinet of a kite wing mounted on the carrier cable of the system;

- Figure 3 is a front view of the base cabinet of Figure 2 and

- Figure 4 illustrates the quasi-permanent load maintenance of the wings of the system of Figure 1.

The wind system which will now be described here comprises three kite wings 1, 2, 3. Each wing is fixed, by a basic box which will be discussed below, to a carrying cable 4 which is mounted to rotate, here again, around two wheels 5, 6 spaced from one another, here always of the same diameter, installed on the ground and mounted to rotate about a vertical axis. The two wheels are arranged in the same horizontal plane. The first wheel 5 is free to rotate. The second wheel 6 is mounted on the shaft 50 of an alternator.

Each wing is connected to the cable 4 by a central front traction hanger 7, fixed to the leading edge of the wing, and two rear lateral control lines 8, 9. In reality, the control lines also contribute a little to traction, for around 20%.

The carrying cable 4 has two strands 10, 11 parallel between the two wheels 5, 6. Under the wind action, the wings, by means of their base boxes, can therefore drive the carrying cable 4 wound around the two wheels 5, 6 in a series of angular displacements of 360 °, the two strands 10, 11, between the two wheels 5, 6, moving in opposite directions along the two sections 12, 13 here parallel and tangent to the two wheels 5, 6.

2017/5669

BE2017 / 5669

The installation on the ground of the wheels 5, 6 and of the carrying cable 4 is such that the wings remain in charge almost permanently. Referring to Figure 4, this will be explained.

FIG. 4 schematically represents the installation of FIG. 1 seen from above with the carrying cable 4, the wheels 5, 6 separated from each other and the wings 1-3, with their traction hanger 7.

The two strands 10, 11 of the cable 4, between the two wheels 5, 6, move respectively in opposite directions 15, 16.

Let 14 be the direction of the wind, here substantially orthogonal to the strands 10, 11 of the cable. A component of the wind loads the wings 1 and 2 in such a way, as illustrated in FIG. 4, that they drive the strand 10 of the cable 4 in the direction 15, from the wheel 5 towards the wheel 6.

On the other hand, the same component of the wind loads the wing 3 in such a way that it drives the strand 11 of the cable 4 in the direction 16, opposite to the direction 15.

Wings 1-3 are therefore almost always in charge.

Admittedly, it must be admitted that along part of the sectors of the wheels on which the base boxes of the wings pass, they must no longer be loaded. They must be stationary so as not to impede the direction of movement of the carrying cable.

The wings 1-3 therefore almost permanently drive the cable 4 which rotates the wheel 6 and therefore the shaft of the alternator 50, therefore also almost permanently. Energy generation is therefore maintained over 360 °. The system certainly remains in charge at all times, especially if the wings are fixed as specified above. This is the interesting result obtained by the wind system of the invention.

2017/5669

BE2017 / 5669

It will be easily understood that in the case of a wind system in which the base boxes of the wings are driven in a perfectly circular rotary movement, such as along the two wheels of the system of the invention, the wings must be stationary on a good part of the movement of the carrying cable.

For the record, it will be recalled that an alternator is a rotary machine converting mechanical energy into electrical energy. The mechanical energy supplied to the rotor of the alternator - the inductor - induces an alternating current to the stator of the alternator - the armature - by the relative movement of the inductor and the armature which causes a variation of the flux of the magnetic field.

The lines 7-9 of the wings are fixed to the carrying cable 4 by means of a base box 17 pinched on the cable 4, here by two hooks 18, 19, in this case in the manner of ski chairlifts on their carrying cable. The box 17 supports three motorized winches 20-22 on which the lines 7-9 are respectively wound. The winches can be controlled by DC motors.

The height of the wings is regulated by the rotation, in one direction or the other, of the winches 20-22.

Note that the hooks 18, 19 can be detached from the carrier cable to come on a secondary cable for example in the event of maintenance.

As is perfectly known to those skilled in the art, the difference in lengths of the rear lines, for the orientation of the wings and, more generally, the power of the wind system are controlled and controlled using a series of equipment. and electronic components installed both on the wings and on the ground.

On the wings, you can place, in addition to a battery and a charging system, an accelerometer, a gyroscope, a magnetometer, a GPS and a radio device.

2017/5669

BE2017 / 5669 for ground / wing communication. A small calculator can also be on board, of a type used on board drones.

It will be noted that, the wings being connected to the carrying cable by three hangers, their power can be managed by an incidence adjustment and they can also be maintained in any position of the flight window.

On the ground, and independently of the means necessary for takeoff and landing of the wings, strain gauges can be installed in the base boxes for the measurement of the tensile forces of the lines and wings. The power supply, the means of communication and the computer will be determined with care.

In summary, the wind system of the invention makes it possible to recover on the ground the traction energy of kites which can evolve at variable heights as well as with variable wing surfaces. Electricity production is interesting both in terms of the duration of the year and in terms of power. System maintenance is easy and the environmental impact relatively negligible. Regulatory constraints are also quite reduced. Also reduced is the cost of manufacturing and installing the system.

Finally, it should be emphasized that the fact of associating kites with a carrying cable makes it possible to better adapt the system to the desired power and especially to the terrain. A support cable can extend over a very long distance, with more than two support cable support wheels and return and return wheels, and even be installed around natural reliefs, such as hills. In this case, the carrying cable travels along more than two linear sections.
