6 for different frequencies of the incident wave, which variations indicate the manner in which the wave energy is effectively absorbed by the converter of the present invention. Theoretically, the Bessho system is advantageous in that when the natural frequency of the fluid-float system is tuned to the major frequency of the incident wave, the entire energy carried by the incident wave can be extracted from the motions such as heaving, swaying, and rolling of the float relative to the fixed point to which the float is secured through the aforesaid dynamic system (including the damping mechanism, the restoring mechanism, and the mass mechanism), and that the reflected waves and the transmitted waves from the float can be suppressed substantially to zero. Most systems of the prior art to extract ocean wave energy use floats which heave and roll in response to the motion of the incident wave, so that the systems extract wave energy by using the movement of the floats relative to fixed ends thereof secured to coastal ground or the sea bed.

1) The energy absorbing efficiency is high and the frequency range of the incident wave to provide a high energy absorbing efficiency is very wide as compared with that of the prior art, provided that the natural frequency of the converter including the floats is approximately tuned to the frequency of the incident wave, as illustrated by the comparison of the curves (1) through (4) of FIG. Since the fluid-float system has only one natural frequency, the energy absorbing efficiency can be maximized as long as the one natural frequency of the fluid-float system is tuned to the major frequency of the incident wave, but when the nature of the incident wave is changed due to variations of the meteorological conditions or other causes, the major frequency of the incident wave fluctuates and the energy absorbing efficiency is reduced greatly. This wave energy converter is formed so as to extract the wave energy through the dynamic systems between the floats and the links and between the adjacent links, and the natural frequency of the float group is approximately tuned to the frequency of the incident wave.

Accordingly, it is apparent that the Bessho system necessitates preparation of a plurality of float systems with different natural frequencies so as to facilitate interchange of the float systems when the meterological conditions are changed. Thus, the converter of the invention has a high wave suppressing effect over a wide range of wave frequencies.

The operation of the wave energy converter of the invention will now be explained. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to obviate the aforesaid shortcomings of the prior art, by providing an improved wave energy converter. In mooring the wave energy converter of the invention, due care should be taken so as to ensure sufficient length of the mooring rope or chain for allowing free heaving, swaying, and rolling of the floats, and to ensure sufficient clearance from fixed structures of the piers and breakwaters for preventing the wave energy converter from colliding against such fixed structures. The present invention obviates such shortcomings of the prior art.

The wave energy converter of the invention is more suitable for producing a large number of units, each unit having a medium rating such as several hundred kW suitable for ensuring a high mechanical efficiency, rather than for producing one unit of very large scale, and such converters of medium ratings can be disposed in the vicinity of ports and coasts not only for energy extraction but also for wave suppression. Each of the thus divided two air chamber portions is connected to two intake ports 7 and 8 through intake valves 7A, 7B, 7C and 7D and is connected to two discharge passages 9 and 10 through discharge valves 8A, 8B, 8C, and 8D, as shown in FIG.

3A. The two intake ports 7 and 8 are disposed substantially at diametrically opposite positions of the air chamber 5 relative to the shaft 6A, and the discharge passages 9 and 10 are similarly disposed at diametrically opposite positions of the air chamber 5. When the rotary blades 6, 6 secured to the shaft 6A turn in the directions of the solid line arrows of FIG.

Fisioterapia a domicilio - Fisiohogar FIGS. 4A and 4B illustrate another example of a mechanism to convert the aforesaid relative movement due to the wave energy into air flow to drive a unidirectional air turbine which is installed in the air passage. This invention relates to a wave energy converter suitable for absorbing ocean wave energy. More specifically, the invention relates to a wave energy converter having a group of at least two floats connected by elongated rigid links disposed at a right angle to the direction of incidence of the waves, which floats are free from the coastal ground and sea bed and are allowed to heave, to sway, and to roll, so that a dynamic system is formed to absorb energy from relative movements between the floats and the links and between the adjacent links, while the natural frequency of this system is approximately tuned to the frequency of the incident wave, whereby the energy absorbing efficiency is remarkably increased and the frequency band having a high energy absorbing efficiency is widened.

FIGS. 3A, 3B, 3C(A) and 3C(B) illustrate one example of a mechanism to convert the aforesaid relative movements due to the wave energy into a one-way air flow to drive an air turbine 11, the rotation of the air turbine being transmitted to an electric generator 12 for producing electric energy. Dolor de espalda hombros y brazos . Relative movements the three floats and the two links were considered while assuming that the float shape and the selection of the coefficient of viscous damping and the distance between the floats was the same as those of the previous 2-float system. The Bessho system of the prior art uses one float which is secured to the coast or sea bed through a dynamic system including a mass mechanism, a restoring mechanism, and a damping mechanism, so that the energy carried by the wave is transmitted to the dynamic system through the float so as to produce specific phase differences between the float movement and the wave, which phase differences facilitate energy extraction and wave suppression.

Besides, the energy conversion efficiency of the converter of the invention is practically unaffected by normally expected changes in the nature of the incident wave due to variation of the meteorological conditions, so that a high energy absorbing efficiency can be maintained regardless of weather conditions. 6, the values of l’ and μ0 ‘ were selected so as to obtain maximum efficiency at the prescribed dimensionless angular frequency ω2 D/g by a computer. The reciprocating movements between the floats 1 and the link 2 and between the adjacent links 2 can be converted into rotary motions, for instance by a crank means or a clutch means. FIG. 2B shows another model of the invention, which uses three floats connected in a linear fashion by two links 2. Each of the joints between the float 1 and the link 2 is provided with a restoring means 3 and a damping means 4, so as to form a dynamic system 5A there.

Two floats 1, 1 are pivotally connected to a link 2 and restoring means 3 and damping means 4 are provided between the link 2 and each float 1 as shown in the figure. For instance, each of the floats in the converter of the invention may have a width of 5 m, a draft of 5 m, and a cross-sectional area of 23.8 m2. Each combination of the float 1 and the link 2 through the restoring means 3 and the damping means 4 forms a dynamic system 5A. Incident wave W propagates on the sea surface 6B, in the direction of the arrow of the figure. T is the amplitude of the total transmitted wave. The shape of the link 2 of FIG. The curve (2) of FIG.

Besides, the wave energy converter of the invention is particularly suitable for installation at isolated islands to generate electric power while suppressing waves. Kx) travelling leftward satisfy the following equation (11) if the wave energy is not extracted and the following equation (12) if wave energy is extracted. Dolor al estirar la rodilla en la parte de atras . Besides, the float with one end thereof fixed or restricted is susceptible to breakdown by high waves of typhoon or the like. ∞ upon the float. Nevertheless, it is desirable to moor the converter by a long rope or chain in a manner similar to the mooring of a ship. 5 including the floats L and R and a link 2 will be described first. Thus, the dynamic system may destroy itself when extraordinary forces act thereon, and it is hard to protect the dynamic system against foreseeable severe conditions at reasonable cost.
