Abstract

A device for generating energy from water flow such as tides or waves has a vertical axis turbine, and flow guides shaped to ensure that the water always rotates the turbine in the same direction. The guides may be arranged in a square arrangement so that water flow from any direction drives the device. The flow guides may be funnel shaped and there may be gates E to allow the device to be closed. The device may have a concrete base and be built on the sea floor. A number of devices may be arranged in a dam to form a breakwater or barrage. The device may also be used in a river where it may only two openings to accept river flow (figures page 3).

Description

<p>Description</p>
<p>Tide Wave Power Generator * The water because of the ebb and flow is in a constant move, this is increased further by the wind taking on the form of waves.</p>
<p>* The energy resulting from the movement of the water can be used to generate electric current.</p>
<p>* The substance of my invention is that no matter which direction the water is flowing from, it always rotates the turbine in one direction.</p>
<p>* The shaft of the turbine is in a vertical position.</p>
<p>* The side-walls which direct the water towards the turbine can be made from metal when using them in smaller units or from concrete when using them in bigger separate, as well as in connected chains built into dams.</p>
<p>* The tide wave power generator can be constructed in different sizes according to the requirements.</p>
<p>* There are several substantial differences compared to the ones previously invented: 1. the solid concrete base 2. the water flowing in a funnel shape 3. the peculiar shape of the side-walls 4. the construction of the dam 5. this tide wave power generator is sunk under water My invention has three (3) different versions: 1. The version of separate units 2. The version built into systems of dams in the form of chains 2/1 e.g. built into the breakwater dams of harbors or into dams made to protect different parts ofieres in order to bring the flood under control 3. The version applied for rivers 3/1 According to the requirements it can be constructed alongside bigger streams or rivers in different sizes.</p>
<p>Tide Wave Power Generator 1. The version for separate units 1/1 A, On the contrary to the previous ones, it stands on a solid concrete base.</p>
<p>B, The position of the side-walls is aerodynamic and funnel-shaped, whereby the pressure effecting the turbine is increased 1/1 "-a-b-c-d" The flow of the water into the turbine is similar in all three versions. 1/1 Fig.! C, The tide wave power generator is put under water (on a solid concrete base). it is only its upper part which can be seen on the surface of the water.</p>
<p>D, No matter which direction the flood is flowing from, the waves always rotate the turbine in one direction 1/1 Fig. 2 E, The peculiar construction of the turbine 1/1 Fig.2 2. The version built into systems of dams in the form of chains 2/1 e.g. . built into the breakwater dams of harbors or into dams made to protect different parts of riuroides in order to bring the flood under control.2/1 "D" My invention differs substantially from the previous ones in that point that the water flowing either from the right or from the left into the turbine it always rotates the water in one direction. There are gates in the side-walls on its open sea side which can be in a closed position during the flood. 2/1 To increase the efficiency there is a small "water-diverting island" 2/1 "C" The generator is put into the side-walls 2/1 "G" 3. The version applied for rivers 3/1 It is based on a solid concrete base, sunk under water, with on its upper part to be seen but luring the flood even this part is covered with water.</p>
<p>On the contrary to the previous older water-mills the flood or during winter time, the frost has no effect on my invention. This is achieved by the peculiar construction of the breakwater side-walls.</p>
<p>3/1 "A and B" The generator is put in the side-waIls 3/1 "G" The part near to the river -"R" riverside The Tide Wave Power Generator The flow of the sea water, the ebb and flow and the waves of the sea can be used to generate electric current.</p>
<p>My invention has three different versions.</p>
<p>1. The version for separate units 1/1 2. The version built into systems of dams in the form of chains 2/1 3. The version applied for rivers 3/1 The substantial differences of my invention in comparison with the previous inventions: * The shape of the side-walls (their funnel shape) * Being put on a solid concrete base * Being sunk under water The flow of the water is similar in all three versions 1/1 Fig. 1 1. The separate units are put on a concrete base, and no matter which direction the is flowing from, * it always rotates the turbine in one direction 1/1 Fig.2 2. Built into dams in the form of chains 2/1 Because the water does not always flow continuously from the same direction, changing its direction as well, that is why it is important that the water flowing from either left or right into the turbine rotates it in one direction. 2/1 I achieved this by developing specially constructed side-walls which results in a turbine having increased efficiency.</p>
<p>3. It is put on a solid concrete base sunk under water whereby it is not affected by frost or flood.</p>

Claims (2)

<p>Claims Tide wave power generator A.
1. A solid concrete base with the
shape of a fru strum pyramid.</p>
<p>2. Its right and left side walls are curved and aerodynamic thereby directing the water onto the wheel of the turbine with higher efficiency.</p>
<p>3. The upper part of the generator consist of two pats, the lower part of which has four side walls consisting of four trapezium forming the shape of a frustrum of pyramid. The upper part resembles a flatten pyramid. The generator is placed in the area closed between these two forms.</p>
<p>4. There is a funnel shaped created by the right and left side walls, the curved lower part with its trapezium shape and the upper part, thus increasing the pressure of the water onto the turbine.</p>
<p>5. The hole flowing onto the turbine is 1/3 of the outer part of the funnel shape.</p>
<p>6. The generator has the same inflowing hole in its four sides so the waves coming from any direction will always keep the turbine in constant move.</p>
<p>7. As the result of the peculiarly curved, aerodynamic side wall mentioned in point 2, the wave coming from any direction will always rotate the turbine in one direction.</p>
<p>8. The four inflowing holes(whiCh can works as out flowing ones if the water flows from the opposite direction)ofle by one leave 1/8 of the turbine wheel open for the inflowing water.</p>
<p>9. The four similar side walls one by one consist of three parts having peculiarly curved three sides where the side close to the turbine covers 1/8 of the turbine wheel.</p>
<p>10. The turbine wheel has more than twelve blades, hence it is always under the same pressure because it is covered by the side walls one by one only on a small area.</p>
<p>11. The smaller units are made from metal, the bigger from concrete. B.</p>
<p>1. It is a solid concrete damp system having built in several power generator plants.</p>
<p>2. This type of damp systems could be used at smaller bays, mouths of rivers as a swelling damp or it can be built into breakwater damps of harbours.</p>
<p>3. This tide wave power generator makes use of the tide wave energy of sea water.</p>
<p>4. The inflowing hole onto the turbine is similar to the previous one but here there are only two inflowing holes which can works as out flowing ones if the water flows from the opposite direction. These two inflowing holes are completely similar-see drawings.</p>
<p>5. As the water is not flowing evenly but undulating according to my invention the turbine wheel always rotates into one direction.</p>
<p>6. There are little water-diverting islands in front of the damps system and between the power generator. C.</p>
<p>1. The version applied for rivef-the inflowing hole is the same as it was with the two previously mentioned versions but here there is only one and one out flowing one which has a different shape.</p>
<p>2. It is based on a solid concrete base.</p>
<p>3. It is placed under water so it is not influenced by freeze or flood.</p>
<p>4. Placed alongside of rivers, the smaller units are made from metal, the bigger from concrete.</p>
<p>5. In all three versions the inflowing hole is provided by bars to protect it from big fish and wood logs.</p>
<p>Amendineiits to the claims have been filed as follows</p>
<p>CLAIMS</p>
<p>A. The wave power station 1. The wave power station is located under the water, only its upper part can be seen from the water. It is located on a hard concrete base, which has the form of a trunkated flat pyramid.</p>
<p>2. It has four (4) equal curved streamlined basic walls, which are situated on the four corners of the pyramid shaped basis mentioned in the first claim. The four symilar sidewalls are composed separately by three parts. Each sidewall has three special curved sides and the section near the turbine is a circular arc placed on the upper level of the trunkated pyramid shaped basis mentioned in the first claim. The circular arc segments of the four sidewalls make up a circle formation, which separately constitute the 1/8 part of the circle.The 11/8 part free section between the two circular arcs is the inlet gap.</p>
<p>3. The upper side of the power station is composed by two parts: -the upper side is like a flat pyramid -the lower part is an inverted trunkated pyramid, which is situated with its corners on the sidewalls described in the
2. claim. In the space closed by these two pieces we can find the generator.</p>
<p>4. The base described in the first claim, the sidewalls described in the second claim and the upper side described in the third claim straddle a cylinder shaped segment, in which the wheels of the turbine are located. It has more than 12 blades, which are circular arc shaped.</p>
<p>5. Between the two sidewalls mentioned in the second claim, on the basis mentioned in the first claim and between the upper side mentioned in the third claims there is a circular arc shaped division. This one withhelds the whirl that can be produced among the sidewalls and thus the water can flow more efficiently towards the turbine and also contributes to the stability of the power station.</p>
<p>B. The tidal power station 6. It is a hard concrete system, which includes more electricity generating turbines. The inlet gap is symilar to the previously mentioned one but in this case we can find only two inlet gaps, which function also as stream in gaps.</p>
<p>This one is the same in both cases.</p>
<p>7. In front of the baffle system, between the power stations there are water baffling small islands, which divert the water towards the electricity generating turbines mentioned in the sixth claim.</p>
<p>8. The stream in gaps of the turbines described in the sixth claim are closed by gates in case of serious storms or tide rises, which are situated in the side walls,.</p>
<p>C. The fluvial version 9. The fiuvial versions are situated along the banks of the river, but they can also be built in the baffle system.</p>
<p>lO.In the case of the wave power station mentioned in the first claim and in the case of the fluvial version mentioned in the nineth claim the smaller units are * made of iron, the bigger ones are made of concrete.</p>
<p>11.In the case of each version the stream in gap is shielded by bars against bigger fish or treetrunks.</p>
