DESCRIPTION:
BRIEF SUMMARY
The present invention likewise relates to an assembly emitting a signal at the moment when a body, in particular a floating body, has to be pushed in a liquid in which, or at the surface of which, a motion is to be created, so that the deviation between the moment at which a wave or motion passes through a specified state and the moment of pushing corresponds to a determinate value. This assembly advantageously comprises an acceleration sensor connected to an electronic chip or microprocessor.
STATE OF THE ART
Document EP-A-0 236 653 has disclosed a system for generating an artificial swell in a tank. This system comprises a jack solidly fixed to a wall of the tank, the shaft of the piston of the jack carrying a float. The jack thus imparts to the float an alternating motion in a single horizontal plane.
The use of a system of this type in a swimming pool requires substantial work along one wall of the latter.
On the other hand, the use of a system of this type in a swimming pool will have only a random effectiveness. This is because, during the return of a wave (which return is caused by the reflection of a wave from a wall), a plurality of cases are possible, including inter alia: that the motion of the float opposes the return motion of the wave, that is to say that the energy of the float is used to oppose the return motion of the wave; the float to the liquid to be set in motion is slight, since the float is still moving in a single horizontal plane.
Finally, since the float remains in a single horizontal plane, such a float acts as a barrier or energy absorber for a reflected wave.
A device for a swimming pool is likewise known which is contituted by a substantially vertical panel connected to one wall of the pool, firstly by an articulation and secondly by a jack. This known device makes it possible to create waves at the surface of the pool. This device requires substantial infrastructural work. Moreover, the energy transmitted to the liquid will depend on the level of the wave in contact with the panel. Such a device consumes a great deal of energy in order to create waves.
The present invention relates, inter alia, to a device which requires only little energy to create waves, for example in a swimming pool. In fact, the device according to the invention makes it possible, inter alia, to optimise the utilisation of energy to create motions at the surface of a swimming pool.
This is because, in the case of a swimming pool, the device according to the invention is not solidly fixed to a wall of the pool and does not create, as such, a static obstacle to the motions created. It may nevertheless become a dynamic obstacle in one particular form of use, in which the motion of movement of the bodies of the device is controlled to be one quarter-cycle behind relative to the motion of the waves. Finally, the operation of the device may be controlled in order to obtain maximum effectiveness. Thus, it if is desired to obtain motions of maximum amplitude, the device according to the invention will be controlled to be one quarter-cycle ahead relative to the motion of the waves created.
BRIEF DESCRIPTION OF THE INVENTION
The device according to the invention is a device intended to create a motion in a liquid, in particular at the surface thereof, this liquid being contained within a tank defined by one or more walls, in particular in a swimming pool. The device comprises an element in contact with the liquid in which, or at the surface of which, a motion is to be created. This element is a floating or submerged assembly, not solidly fixed to a wall of the tank, the said assembly comprising two bodies mutually connected by at least one means, this means being intended to move the bodies relative to one another in a manner such as to create a motion in the liquid, in particular at the surface thereof.
An assembly not solidly fixed to a wall of the tank is understood to mean two bodies mutually connected by a means which forms a floating or submerged assembly free of any motion in the liquid or at the surf
