4,083,189 issued to Fetkovich discloses an apparatus for utilizing the energy of ocean waves by applying synchronized alternating air pressure to increase the amplitude of the waves until they spill over the confines of the apparatus and onto the blades of a turbine. U.S. Pat. No. 4,083,189 above. U.S. Pat. No. 4,249,383 issued to Molini et al. U.S. Pat. No. 1,768,716 issued to Shishkoff describes a water driven motor is used to drive a friction heater which produces steam. This action is used to adjust the pitch limit of the blades by means of the counterbalances 23 hitting the strike plates.
U.S. Pat. Enfermedades de dolor de espalda . No. 4,309,154 used to Daddario describes a means of powering a pump by the rising and falling of water. It avoids the need for complex, expensive and unreliable means for detecting air motion direction and rotating the blades in response to achieve a single direction of motion of the turbine. The motion of the water surface inside the stack is amplified over the motion in the mouth of the chamber by a gradual narrowing of cross-section between the chamber and the stack. The wave motion, and hence also the air motion in the stack, can be amplified over that otherwise available by choosing either a suitable level depth of bottom or a suitable shape of the bottom and/or shore for the location of the invention. The upper and lower threaded sections of each worm 26 are differentially reverse threaded, in the manner of a turnbuckle, so that axial rotation of any worm causes the threaded holes on the upper and lower strike plates to move together or apart, depending on the sense of rotation.

The axial rotation of the blades responds to the wind velocity through the stack in such a way that the turbine will be urged to rotate in a single direction, regardless of the in or out direction of air flow. This will increase the vertical motion of the water in the stack. Preferably, the location of the stack 2 will be such as to maximize the vertical motion of the wave surface 6. Such locations are found on the shores of large lakes and along the shores of oceans. The arrows above the stack indicate the up and down motion of the air through the end of the stack.
Thus, the side of the blade with the larger area will be the trailing edge of the blade in operation, regardless of the direction of air flow up or down. Since the blade areas on either side of the blade axis differ, and the blades are balanced, each of the blades will rotate about its axis in response to the pressures exerted by air flow in and out of the stack.
The turbine blades are each axially balanced and free to rotate about an axis concentric with the shaft (change their pitch). If the strike plates are parallel, the three worms can be turned simultaneously to move the plates farther or closer to each other while maintaining them parallel. It is an additional object of the present invention to provide an oscillating force turbine that includes the use of an adjustable strike to limit the amount of pivot in the turbine blades.

It is to be understood that the present invention is not limited to the stole embodiment described above, but encompasses any and all embodiments within the scope of the following claims. 1 shows the stack 2 and chamber 4 with the chamber immersed beneath the ocean surface 6. The stack is fixed to the shore 8 by attachments (not shown). The mouth of the chamber is rectangular or oblong, with the longer axis running substantially parallel to the shoreline. If the chamber is near to a substantially vertical wall, the wave amplitude near the wall will be approximately doubled, according to the laws of wave reflection. A torque will be exerted about the axis defined by the shaft 12, causing the blade 10 to rotate toward an angle at which the air is deflected toward the side of the blade having the larger area. Malestar general dolor muscular . As air impinges upon the blade from the side, the greater force will be exerted upon the side having the larger area.
This will yield a great wave amplitude. 1 is a perspective view of the wave chamber immersed in the ocean and the position of the turbine shaft and blades inside the stack. The chamber opening is located just below the surface of the ocean, that is, just below an elevation equal to the mean water level minus the wave amplitude. It is another object of the present invention to provide an oscillating force turbine that utilizes a turbine having pivoting blades that react to the change in air pressure, allowing air flow to exit out the top of the chamber or return into the chamber. This increases the power delivered to the turbine blades 10 in the present invention, and aids efficiency. Wave action causes water to flow in and out of the open end of the chamber, which in turn causes the water level in the stack to move up and down, forcing air to flow in and out of the open end of the stack and past a turbine, which extracts power from the moving air.
Reflection from a cliff such as 8 can double wave amplitude. More particularly, this turbine makes use of ocean wave energy in order to produce power. The hub rotates with the power take off shaft 30, which turns on bearings 32 (only the upper bearing is shown in FIG. The turbine mounted inside the open end of the stack turns as air flows over it, absorbing energy. It is a further object of the present invention to provide an oscillating force turbine that makes use of a chamber in which the top portion narrows in order to increase the resultant velocity of the air flow that flows through the turbine. The present invention relates to turbine devices having bladed rotors for reacting to fluid flow. SUMMARY OF THE INVENTION Applicant presently discloses a unique means to extract energy from ocean waves.
Thus, the ideal environment for the present invention is a vertical cliff face at the termination of a bottom ramp of decreasing depth. This system helps to eliminate the large sized reservoirs need to operate present day hydroelectric stations. Because of the effects noted above, the rise and fall of the water in the stack will be large. The repeated and rhythmic coming and going of ocean swells are utilized to produce variations in air pressure that will drive a bladed rotor on a turbine. The hub assembly consists of hub ring 22, lower strike disc 20 and upper strike disc 24. The ring 22 has an annular cross section (that is, a cross section through a plane lying in the axis of the turbine) which is square or rectangular.
The strike plates are above and below the hub.
FIG. Que tomar para dolor de espalda . 2 is a semi-exploded exploded view of the turbine hub, showing parts of the pivoting turbine blades of the turbine and the hub mechanism that carries the blades, including the striking mechanism which limits the pivoting of the blades. The three parts of ring, upper strike disc, and lower strike disc are connected by threaded cylindrical worms 26 which are rotatably fixed to the ring 22 at their center points, and screw into threaded holes 28 through the upper and lower strike discs, as discussed below. The strike plates are above and below the hub. The separation of the plates is controllable by an appropriate mechanism. The shafts 12 are made of strong material which also, when in contact with the material of the ring 22, has a low coefficient of friction, or, which can be made to have a low coefficient of friction by means of an appropriate lubricant.

The worms can be turned individually in small increments with simple hand tools, or, the worms can be turned simultaneously by a suitable mechanism. For example, chain drive sprockets can be welded to the worms near the ring, and a chain passed around these sprockets for simultaneous turning of the worms.

The drive could also be automated. The stack 2 could also be erected offshore, in reasonably shallow water, by attaching it to the bottom with steel beams or the like. This device interacts directly with the tide or current to produce the power. FIG. 2 shows the turbine hub assembly with the mechanism which limits the pitch change of the blades.
