Definitions
- the present invention relates to a device intended to create waves in a liquid, in particular when this liquid is contained in a basin or a swimming pool.
- Such devices are used, for example, in amusement park pools, but also in test basins for naval and hydraulic constructions.
- the invention also relates to a method of creating waves using said device.
- International application WO 91/14062 discloses a system for generating movements in a liquid, in particular on the surface thereof.
- This system includes a device comprising two bodies, one of which moves relative to the other. This relative displacement creates inertial forces which cause the assembly to move in the liquid. This displacement creates excitations in the liquid which transform into waves.
- one of the bodies is a hollow sphere inside which the second body moves.
- the vertical stability of the device is not satisfactory. In particular, it can overturn when the moving mass is in the high position relative to the hull.
- the members intended to cause the relative movement of the two bodies must be sized to be able to move these large masses, which has an impact on their cost.
- the inertial force generated is proportional to the mass, and to the square of the frequency of the movement. It is therefore not possible to adjust this excitation force independently of the frequency, or vice versa, it is not possible to vary the frequency without modifying the excitation force.
- the organs intended to cause relative movement form an integral part of the device. As such, they are subject to the environmental conditions of the liquid, and are liable to be damaged by the slightest leak in their casing. In addition, they are difficult to access for their maintenance.
- the energy required to set the bodies of the device in motion must be transferred to it, for example by means of an electric cable.
- This cable is driven by the repeated movements of the device. It is likely to wear or break, and therefore presents a danger. In addition, the presence of this cable in the liquid constitutes a discomfort.
- the energy necessary for setting in motion the bodies of the device is stored within the device itself, for example in the form of electrical energy, in a battery, or of pressure energy. , in a tank.
- the need to periodically recharge the device is a drawback in its operation. Also known, for example from EP 0 236 653, or
- the present invention specifically aims to provide a device which does not have the drawbacks mentioned above. Its purpose is to provide a device for generating waves in a liquid which is easy to implement and operate, which consumes little energy, the organs of which in the presence of the liquid are well resistant to the environment in which they are placed, which can be placed in service in an existing basin without requiring modifications to the infrastructure, and which can be easily removed to leave the basin in its original state.
- the invention relates to a device capable of creating waves in a liquid contained in a basin such as a swimming pool, by substantially vertical reciprocating movement of a body placed within the liquid or on the surface thereof.
- the body used for this purpose is a shell capable of being filled with said liquid.
- the hull is connected by a connecting means to a means capable of periodically applying an upwardly oriented force in a substantially vertical direction, then of letting said hull descend.
- the principle of the invention is to transfer energy to the liquid in phase with the kinetic energy of the wave.
- the shell preferably comprises a horizontal bottom and substantially vertical side walls. This favors the vertical movements of the water in the vicinity of the hull.
- a simple hole can be provided at the bottom of the hull.
- the hull may include a flotation element.
- the shell of the device comprises a bottom provided with a plurality of holes. These holes are advantageously able to favor the penetration of the liquid into the shell, and to disadvantage the exit.
- the shell comprises an upper bell-shaped wall, provided with at least one air passage opening.
- This or these air passage openings are advantageously capable of promoting the exit of the air located at the upper part of the hull, and to disadvantage entry.
- the means capable of periodically applying an upwardly oriented force preferably comprises a winch capable of winding and unwinding the connecting means.
- This winch preferably comprises a regulation unit capable of regulating the winding and unwinding period of said winch and the engine torque thereof.
- the invention also relates to a method in which a shell is suspended at a point in the basin, the said shell being partially immersed in the said basin, the action of periodically lifting the said shell for a given period of time and then leaving it come back down.
- the periodicity of the movements imposed on the hull is preferably determined so as to excite a natural frequency of oscillation of the liquid contained in the basin, and the driving torque applied to the winch during the lifting time of the hull so as to get waves of the desired amplitude.
- the engine torque applied to the winch during the duration of the descent of the hull is preferably determined so as to permanently keep the connection means under tension.
- Figure 1 is a schematic sectional view of a basin provided with a device according to the invention.
- Figure 2 is a perspective view of an embodiment of a device according to the invention.
- FIG. 3 is a detailed view of the drum mechanism shown in FIG. 2.
- FIGS. 4, 5 and 6 are sectional views of three variants of the shell of a device according to the invention.
- FIG. 7 is a detail view in section of a variant of the perforated bottom of the shells shown in FIGS. 4 and 6.
- Figure 8 is a detail view in section of a variant of the opening of the shells shown in Figures 5 and 6.
- FIG. 1 shows a pool 1 filled with a liquid 2, such as a swimming and leisure pool filled with water.
- the swimming pool 1 can be rectangular or round, or of any other shape.
- a shell 3 is suspended within the swimming pool 1 by a connecting means 4 which can be a cable, a strap, a rope or a chain.
- a winch 5 comprises a drum 6 on which the connecting means 4 can be wound, and an electric motor 7.
- Periodic oscillations of the water 2 of the pool 1 are obtained by imposing a vertical reciprocating movement of the hull 3 in phase with the waves. The period of this vertical reciprocating movement is determined experimentally so as to excite a mode of oscillation proper to the mass of water contained in the swimming pool.
- the amplitude of this reciprocating movement is determined so as to obtain waves of the desired amplitude.
- the shell can be made of a light, inexpensive and water-resistant material, such as polyester reinforced with glass fibers.
- the shell 3 can be given various shapes, for example cylindrical or parallelepiped. An elongated parallelipipedic shape is interesting in a rectangular swimming pool, and easily makes it possible to obtain various transverse, longitudinal or combined modes of water oscillation.
- a shell 3 with vertical side walls and a horizontal bottom promotes the transfer of vertical movements to the liquid, and limits the turbulence caused by horizontal movements.
- the hull 3 is given a shape such that it presents the least risk for swimmers. The angles of the shell 3 will be rounded.
- a control and regulation unit 8 can be placed close to the engine, or deported to a convenient and accessible location. This box allows the operator to enter the desired values of the period of the vertical reciprocating movement imposed on the shell 3, and of the amplitude of the waves at produce.
- the drum 6 comprises a sensor 9 making it possible to measure its angular position, and to deduce therefrom both the height from which the shell 3 is suspended and the speed of the latter.
- a locking brake 11 keeps the shell 3 in the raised position when the device is not in use.
- a reduction gear 10 adapts the speed of rotation of the electric motor 7 to the speed of rotation desired for the drum 6. This reduction gear 10 transfers the motor torque to the drum during the raising of the hull, and allows the drum to rotate in the opposite direction during from the descent of the hull.
- the shell 3 is advantageously provided with at least one hole 12 so that the water 2 from the swimming pool can enter the shell 3.
- the shell can be filled from above.
- the water contained in the shell 3 gives the assembly a mass which allows it, after being lifted by the winch 5, to descend under the effect of its apparent weight.
- the addition of flotation elements 13 makes it possible to obtain that the hull, once submerged in the swimming pool, retains the ability to float. This is however in no way necessary, and shells capable of sinking can be produced without departing from the scope of the invention.
- the holes 12 allow the shell 3 to cling to the liquid 2 to stir it well. They also prevent excessive movements of the shell 3 relative to the liquid 2.
- the position of the shell 3 and the period of the alternative movements imposed on it are determined experimentally so as to excite a specific oscillation mode of the swimming pool 1, so as to obtain waves of the desired shape.
- the excitation of one of the basin's own oscillation modes makes it possible to obtain waves in the form of standing waves, comprising nodes and bellies at fixed points in the pool, without significant energy input.
- the shell 3 is preferably placed in the vicinity of a belly of the desired oscillation mode.
- the movements of a particle of water in the vicinity of such a belly of the swimming pool's own oscillation mode are mainly vertical.
- the shell 3 preferably has walls vertical side, so that it does not impose on the surrounding water movements having a horizontal component, which are not part of the desired oscillation mode, and are therefore a source of energy dissipation.
- the motor 7 is preferably a direct current and low voltage motor, meeting the safety standards which apply to swimming pools. It can however also be an AC motor or a pneumatic or hydraulic motor.
- the regulation of the motor current is ensured by the control and regulation unit 8.
- This control and regulation unit 8 makes it possible to determine the amplitude of the movement which is desired. It contains a regulator, for example of proportional-integral type, allowing the regulation of the current in the engine during the periods of traction on the hull, in order to obtain the waves of desired amplitude.
- the amplitude of the waves actually obtained can be deduced from the movements of the shell 3. In fact, the latter moves little with respect to the surface of the liquid.
- the movement of the shell 3 is determined by measuring the angular position of the drum.
- the control and regulation unit 8 can also regulate the traction times and the absence of traction on the hull.
- the duration of traction is substantially equal to the duration of absence of traction.
- FIG. 2 represents an exemplary embodiment of the invention.
- a support structure 14 makes it possible to install the winch 5 above the surface of the pool 1. Such a support structure 14 is necessary in open-air pools.
- a diving board can be used as a support structure 14. When said support structure is designed to be able to be moved, it is possible to easily choose the point of application of the excitation given to the surface of the liquid 2, and thus influencing the shape of the waves obtained.
- Hull 3 is rectangular. Its length is 3 m and is oriented parallel to the short side of a rectangular swimming pool 1. The width of the hull 3 is 0.75 m. The weight of the hull is 45 kg.
- the hull 3 is provided with a pointed or curved protective cover, sufficiently high, so that the swimmers cannot cling to it or settle there.
- the connecting means 4 is a set of two belts fixed at points situated on either side of the protective cover. Good hull stability is thus obtained 3.
- the winch mechanism 5 specific to this application is shown in FIG. 3. It includes a return pulley 15 free to rotate around a horizontal axis, and a drum 6 secured to 1 output shaft of the electric motor 7 or of its reduction gear 10, on which the two belts 4 are wound, by overlapping.
- Figures 4, 5 and 6 show variants of the shell of a device according to the invention.
- the shell shown in Figure 4 has a large number of holes 12 in its horizontal bottom.
- these holes have a profile such as that shown in FIG. 7, which promotes the penetration of water into the hull during the descent thereof, and favors the exit of the water during the rise of this one. Therefore, the water level in the shell 3, which varies during the reciprocating movements thereof, is established at a level higher than that which it would have in the absence of such a profile.
- the hull is, on average, sunk deeper into the water. This makes it possible to apply a higher tensile force to the shell, without risking extracting it from the water.
- the lateral faces of the shell 3 are extended downward by fins 16. These fins 16 accentuate the suction effect during the upward movement.
- the shell shown in Figure 5 has no bottom, but is bell-shaped, open from the bottom and closed from above.
- the upper part of this bell has one or more air passage openings 17.
- this or these passage openings air 17 are provided with a valve as shown in Figure 8.
- the blocking ball 18 lifts and allows the exit of air during the descent of the hull.
- said ball 18 is applied to its seat.
- Said seat is provided with grooves 19, so that an air flow is nevertheless admitted during the rise of the shell 3.
- this promotes the exit of the air and the penetration of water into the hull during the descent thereof, and disadvantages the entry of air and the exit of water during the rise thereof.
- the water level in the shell 3, which varies during the reciprocating movements thereof, is established at a level higher than that which it would have in the absence of such a valve.
- the shell 3 is, in average value, driven deeper into the water. This also makes it possible to apply a higher tensile force to the hull, without risking extracting it from the water.
- FIG. 6 shows a shell 3 having both the characteristics of the shells shown in Figures 4 and 5, namely a perforated bottom, and an upper bell-shaped portion.
- the daggerboards were not provided, for security reasons.
- the device according to the invention can easily be installed in an existing swimming pool, without modifying its infrastructure.
- the winch 5 and its control unit can be fixed to the ceiling of the swimming pool.
- one or more deflection pulleys make it possible to install the control unit at the edge of the swimming pool 1 or in a neighboring room.
- a structure 14 comprising a pole makes it possible to suspend the shell 3 at an appropriate point in the basin 1.
