Fixed to and extending from the top of sensor float 158 is an upstanding switch actuator rod 159 located radially within the tube 19 for free vertical movement therein by suitable guide means preferably adjacent the top and bottom thereof bearing on the tube 19, such guide means including for example a slide block 159a fixed near the top of rod 159, and the float 158 itself near the bottom of rod 159. The top of rod 159 carries a switch actuator ramp 160 fixedly thereon. A sensor float 158 is freely vertically movable in the tube 19 and rides on the water surface therein at the level Lt, so as to rise and fall with such level and thereby measure calm (mean) water height.
Beams 13 and 13a are preferably spaced at approximately equal distances above and below, respectively, the average level of the surface S of the water, such that at mid-tide (if in a body of water where tides exist) on a calm day (such that no waves are present) the surface S of the body of the water will lie approximately half way between the beams 13 and 13a. In the particular embodiment shown, the members of the frame 5 are shown as I beams welded together, but it will be understood that the frame 5 may be constructed of rigid members of any desired configuration rigidly fixed to each other to make the frame 5 rigid. The wave harnessing apparatus further includes a cable system comprising cables 11 and 11a (which may be cables, chains or other conventional elongate flexible tension members).
6) fixedly connected by end straps 141, rotatably carrying the respective wheel pairs 12b and 12g and having respective central members 142 and 142a threadedly receiving the screw 18b therethrough. Thus, an object of this invention is to provide a wave energy converter employing a float and harnessing mechanism connected to and driving a closed loop hydraulic circuit which pumps oil from a cylinder to a hydraulic motor and so arranged as to overcome the abovementioned disadvantages of the prior art. The prior art systems heretofore proposed have met with little success in being put to practical use due in part to lack of sufficient attention to the actual conditions found in the waves and tides. Operation of the reversing motor 18a continues until downward motion of the wave has opened switch 171 again or the rightward motion of the carriage 138 has continued sufficient to open the normally closed switch 147′. Opening of either the switch 147′ or switch 171 breaks the current loop through the battery 176 and stops the motor 18a. It is possible that the switch 171 may open and close several times, due to the advent of several waves, before the float 10a comes up to the desired calm water position.

On the contrary, the motor 18a operates to pull the carriage 138 rightwardly in FIG. The abovedescribed switches 147, 162, 163, 171 and 172, the reversible motor 18a and an electric power source 176, here schematically indicated as a battery, are wired together in circuit in the manner shown in FIG. While five switches 147 and five switches 162 are shown, it will be understood that more switches, more closely placed, can be employed so as to locate more closely together the several calm water positions available for the float 10a. It is also contemplated that different types of sensing and feedback circuits (e.g. While no hydraulic head pressure is required in the oil supply reservoir 124, it should provide a flooded suction for the cylinder pump 17. Dolor muscular en la espalda baja . The accumulator 127 returns a sufficient volume and pressure of hydraulic fluid to the circuit during the non-productive portion of each stroke of the cylinder pump to maintain generator RPM.

OPERATION While the operation of this apparatus has been indicated above, same will now be summarized for convenience in reference. The WEC 1 further includes a wave harnessing apparatus 10 (FIG. Other objects and purposes of this invention will be apparent to persons acquainted with apparatus of this general type upon reading the following specification and inspecting the accompanying drawings. Accordingly, a need still exists for an economical and practical system that will allow for variations in the wave energy source and provide an efficient means of conversion of energy, tapped from that source, to a useable state. 166a to tide switch 163 and through the rightward movable contact 163a thereof to normally open switch 171. Switch 171 will be in its normally open position if the float 10a is static or is falling with a wave and will only be closed if a wave is lifting the float 10a upward at the time.
9) up through a common line 166 to the now closed contact of normally open switch 162′, through a line 162a’ to normally closed switch 147′ (shown open in FIG. The float positions (a) through (h) in FIG. Preferably, the ends of the float 10a are spaced from the pilings 14 and the float 10a is prevented from moving into contact with the pilings 14 by suitable tensioning of the cables 11 and 11a at the front and back sets. The abovedescribed set of cables 11,11a and pulleys 12a-12h and 21 and tensioning screws 41,41a is provided on the front side (as seen in FIG. The above-described pulleys, sheaves, cables and tensioning screws are preferably substantially coplanar. The frame 5 is preferably fixed to the ground, or bottom, 15 beneath the body of water at a distance from shore where the average depth H (FIG.
Pulleys 12d and 12e are rotatably mounted on plates 46 fixed on the lower beam 13a, right angle pulleys 12a and 12f are rotatably mounted on brackets 47 fixed beneath the upper beam 13, and reversing pulleys 12c and 12h are mounted for rotation on plates 48 fixed on the upper beam 13. These plates and brackets are fixed to the beams 13 and 13a preferably by welding. The beams 13 and 13a are vertically separated sufficient to avoid immersion of top beam 13a in the expected maximum height wave at high tide or expected high water. FIG. 9 is an electrical schematic of the tide adjuster circuitry. FIGS. 4A and 4B are schematic views used to show the wave action on the float of the FIG. FIG. 5 is a schematic view of the hydraulic circuit of the FIG.

A cable and pulley arrangement changes the direction, travel and force of the wave energy action imparted on the float and drives a hydraulic circuit. The hydraulic motor drives a load such as an electric generator. Some others store water in an elevated reservoir to be used as a hydraulic head for a water turbine.
Still others attempt a direct mechanical coupling to the ultimate load to be driven. The near end of screw 18b is supported on bracket 136 by antifriction thrust bearings 149 and nuts 150 in a conventional manner. Dolor despues de infiltracion hombro . As the wave surface S rises, the buoyancy of float 10a causes it to rise and thereby continue to pull the piston 64 to the left. Wave surface S falls to where buoyancy of float is no longer greater than weight of float 10a and weight of float 10a overcomes system preload forces that tend to hold the float in place. Float 10a rides at peak of wave.

The cables 11,11a are always under tension when imparting the forces acting on the float to the system. If desired, the battery 176 of FIG. In the particular embodiment shown in FIG.

Es normal sentir miedo cuando el tigre viene a por ti, pero no cuando debes acudir a una fiesta. Es un mecanismo de supervivencia, si por ejemplo vemos un tigre entre unos arbustos sentimos miedo, que es lo que nos hará huir.
