Description

 Device for recovering and transforming the kinetic energy of a moving liquid

Field of the invention

The present invention relates to the kinetic energy transformation of a liquid, e.g. ex. of a watercourse, in another form of energy, p. ex. electric.

State of the art

 There are many systems for recovering and converting the kinetic energy generated by a moving liquid into electrical energy. Such systems are in particular described in the patent documents US 5,548,956, US 6,323,563, US 2003/123983, US 2012/230021, WO 99/45268 and WO 2011/023166.

General description of the invention

The invention relates to a device for recovering the kinetic energy of a moving liquid in an open conduit. By "open conduit" is meant a conduit such as channel, wherein the liquid has an interface with a gaseous medium, such as p. ex. atmospheric air.

 More specifically, the invention relates to a device as defined in the claims.

 The device according to the invention is an alternative to devices of the state of the art. It also has several advantages, in particular its simplicity of implementation and the fact that the submerged portion is generally limited to a wing portion portion. The maintenance of the device is thus facilitated and its extended life.

 The device according to the invention can be advantageously used in natural watercourses (rivers, rivers, etc.) but any other similar use with a moving liquid can be envisaged. As mentioned previously, the device is preferably designed to minimize the immersed portion. However, it is perfectly possible to immerse several parts or the entire device.

The device according to the invention is not limited to particular dimensions, to a specific number of subassemblies or to particular materials. Similarly, the presence of connecting rods, jacks or oscillating frames is not necessary. Other equivalent systems can be used.

Detailed description of the invention

The invention will be better understood hereinafter by means of an embodiment illustrated by FIGS. Obviously, the invention is not limited to this embodiment.

FIG. 1 shows an exemplary device according to the invention.

The device illustrated in particular in Figure 1 is as a comb composed of a row of identical subsets 2 aligned on a beam 11 passing through a stream 1, p. ex. a river or a canal.

 A subassembly 2, see in particular FIG. 2, is composed of a blade 5.8 mounted on an oscillating frame 9 with in particular an incidence control rod 10 and force transfer rods 4.

A blade is made of a profiled wing section 5, fixed at the end of a handle 8 and at least partially immersed in the stream 1. The wing section 5 is the lower part of the blade, the sleeve 8 is the upper part.

 The upper end of the handle 8 is fixed to an oscillating frame 9 by two bearings 13, 14 which leave the handle 8 and the wing section 5 the freedom of rotation on the axis 6 of the handle 8. This makes it possible to generate a angle between the plane of symmetry of wing section 5 and the direction of movement of the watercourse 1.

 The oscillating frame 9 is attached via two additional bearings 15,16 aligned on beam 11 defined along a transverse axis 12 disposed in a substantially horizontal plane and crossing the stream.

 The frame 9 can therefore oscillate from right to left in a plane perpendicular to the direction of the movement of the stream 1.

 As can be seen in FIG. 5, when an angle of articulation between the plane of symmetry of the wing section 5 and the direction of the movement of the stream 1 is generated by means of the incidence control rods 1 , the latter exerts a force on the profile of the wing section 5. This force is oriented in a direction perpendicular to the plane of symmetry of the wing section 5.

The wing section 5 is positioned on its handle 8 so that the point of application of the aforementioned force is close to the axis of rotation of the handle 8 and behind it, so as not to generate a low torque, tending to decrease the aforementioned angle (see Figure 6). The force is also perpendicular to the horizontal axis of rotation 7 of the frame 9 and away from it by the length of the handle 8 added to about half the length of the wing section 5 and therefore generates a torque significant rotation around this axis 7.

 This couple oscillates each subset 2.

 A pendulum movement is obtained by inversion at the end of the stroke of the angle of incidence between the plane of symmetry of the wing section 5 and the direction of movement of the stream.

 As indicated above, the angle of incidence is controlled by a mechanism comprising a control rod 10 but also a control arm 17 and a linear positioner 18. The control arm 17 is fixed to the handle 8 at a height close to its height. virtual point of intersection with the horizontal axis 7 of the frame 9. At the end of the arm 17 are fixed two control rods 10 by articulated points, joining the control arms 17 of the adjacent sleeves 8 so that the angles d The incidence profiles-liquid are identical for all subassemblies 2. At the end of the row, the last link 10 is connected to a linear positioner 18 controlled by a digital control system that optimizes the angle of incidence by depending on the speed of the liquid, the instantaneous speed of rotation and the power required.

 The force generated in the blade 5, 8 is transmitted by a set of connecting rods 4 connecting the adjacent frames 9. The last rod 4 of the row actuates a jack 3 which pumps oil into a pressure tank (not shown).

 This flow of pressurized oil actuates a hydraulic motor coupled, for example, to an electric generator. This hydraulic energy can also be used directly for the action of cylinders or other systems operating by fluid under pressure.

The main beam 11, crossing the stream 1 and supporting the subassemblies 2 and the positioning motor and the pump jack 3, is fixed on the edges of the stream 1 by means of a support 19 and a transverse axis of rotation 12 parallel to the axis of the beam 11. The beam 11 can thus rotate about this transverse axis 12, oriented perpendicularly to the direction of movement of the liquid 1 and located well above the its surface. By doing this, by means of a jack 20, this rotation leaves the blades 5,8 of the stream 1 and puts the device in the rest or maintenance position (see Figure 7).

The subassembly illustrated in FIGS. 8 and 9 is very similar to the previously described subsets. It differs in that the second axis 7 is not horizontal in operating mode but forms an angle with the surface of the water 1. Expressed differently, in this variant, the second axis 7 is included in a plane defined by the direction of movement of the water 1 and the vertical.

This variant reduces the risk of snagging objects that move in or on the surface of the water, e.g. ex. plants or branches. Finally, it should be noted that in the case of a river or a relatively constant river, the use of a hydraulic mechanism under pressure is not necessarily necessary.

 In this context, and more generally in any similar context, the reciprocating motion can be transformed into a circular by a simple crank-crank assembly, and the constancy of rotational speed ensured by the enslavement of the incidence of the blades.
