Description

Drop and Go Turbine
The present invention relates to a method, an arrangement and a system for producing or generating power, in particular electrical power, from mechanical movement caused by water flow or waterfall, such as, e.g., river currents, streams, waterfalls, etc. The invention can be suitable for shallow rivers and/or for strong and quick river currents / streams, as well as for waterfalls.
Utilization of the so-called "green" or renewable energy can contribute significantly to solving the global problems related to shortage of energy and to greenhouse gases from fossil fuels, coal-fired power plants and nuclear power plants.
This has lead to the development of several turbines and systems for generating electrical power by utilizing the relatively large (kinetic) energy found in water flows, such as for example tidal, ocean and river currents.
However, many of the above turbines and systems are structurally extremely complex or large, rather inefficient and/or not operative at all.
In addition, a need exists for producing energy at places where no infrastructure has been constructed or where the infrastructure has been damaged or destroyed due to natural and/or other forces.
A purpose and/or object of the present invention is to provide a more compact and reliable method, turbine and system for recovering mechanical kinetic energy found in water flow or movement, such as e.g. river currents, streams, waterfalls, etc.
Another object and/or purpose of the present invention is to provide a more efficient method, turbine and system for recovering the above energy.
Still another object and/or purpose of the present invention is to provide a turbine, an arrangement and a system, as well as its elements / components, to be available as stock goods, that is to be able to be stored in a certain place and in a suitable manner.
A further object and/or purpose of the present invention is to provide a concept in the form of a turbine and a turbine system for providing locally generated and self-sustained energy to customers and being compact and/or mobile, as well as easy to construct, transport, handle and/or maintain / service or repair. The turbine assembly and system are mobile and movable by a truck, boat and/or helicopter. Weights and sizes may also be based on the requirements for ease of transportation and/or the energy production requirements (e.g. produced kWh).
A still further object of the present invention is to provide alternative methods, turbines and systems for energy recovery and/or for production of electrical energy.
Also, the invention shall not involve any (adverse) environmental impact neither during installation, operation, maintenance nor removal.
This is achieved by means of the independent claims of the present invention. Additional features of the invention are indicated in the dependent claims.
The invention relates to a system for generating electrical energy from mechanical movement caused by water flow or waterfall, such as for example river currents, streams, waterfalls, etc. The system comprises a turbine device. The turbine device comprises a housing. A suitable turbine in the turbine device comprises a shaft or axle supported in the housing by means of bearings. The housing has an inlet opening and an outlet opening, as well as a flow passage therethrough. The flow passage stretches / extends from the inlet opening to the outlet opening. The turbine can be arranged in the housing in such a way or manner that only 60% or less of the production area thereof is arranged in the flow passage, i.e. is exposed to the water flow or movement going through the passage. In one embodiment, 50% or less of the production area of the turbine can be arranged in the flow passage, i.e. can be exposed to the water flow or movement going through the passage. On the inlet side of the flow passage in the housing, a flow control device can be arranged in order to alter or change the exposure of the production area of the turbine from approximately 60% to almost 0% in accordance with / depending on at least one of: the current velocity / speed and the desired electrical energy production.
The housing of the turbine device can be quadrangular or tubular, but not limited to only these shapes. The inlet and outlet openings can be tubular, but not limited only thereto. The flow passage can be tubular, but not limited only thereto.
The area in the housing, not constituting the flow passage, can be arranged to constitute several chambers ortechnical rooms. The chambers ortechnical rooms can be watertight / waterproof.
A gear or gear box, or belt or chain drive with gearwheels, a generator, a dynamo, a converter and optionally other technical installations / assemblies / components / parts / elements can be enclosed and/or sealed within at least one chamber or technical room in the housing.
When a belt or chain drive with gearwheels is used, the gearwheel or reduction factor can for example be 1:10, but not limited only thereto. The gear or gearwheel factor can depend on the stream / current velocity / speed.
In the flow passage, the cross-sectional area at the inlet opening can be bigger than the cross-sectional area just before the turbine, thus providing for a constriction or narrowing of the water flow in the passage. In this manner, speed increase of and/or pressure increase of the water flow in the passage, just before the turbine, is being achieved. This constriction or narrowing portion of the flow passage can be bottleneck-shaped orconical. However, other forms of the narrowing portion can be possible. The flow control device can be arranged in this narrowing portion. In another embodiment, the flow control device can constitute said constriction or narrowing in that portion of the passage.
These and other features of the present invention will be better understood and described in connection with the detailed description, in conjunction with the drawings, in which: Figures 1A-1B show a general concept of a system according to the present invention, Figures 2A-2C illustrate different embodiments of the system according to the present invention, Figures 3A-3D illustrate, in more detail, different views and/or sections of embodiments of turbine devices for the system according to the present invention, Figures 4A-4C show, in more detail, different views and/or sections of another embodiment of a turbine device of the system according to the present invention, Figures 5A-5B show one embodiment of a grid or lattice arrangement for the inlet opening in the turbine device or possibly for a water intake pipe (see also figure 6B), and Figures 6A-6B illustrate different views of a water intake pipe håving wings or spoilers and a grid or lattice arrangement and/or a flange or branch piece or part of the system according to the present invention. Figures 7A-7B show two views of another embodiment of a straight flange or branch piece or part for the system according to the present invention. Figures 1A-1B show a general concept of the present invention. A system 1 is given for generating electrical energy from mechanical movement caused by water flow or waterfall, such as for example river current, steam and waterfall. The system 1 comprises a turbine device or arrangement 10. The turbine device 10 can be anchored or moored 14 to the bottom 200 of the river by a mooring arrangement 14. The turbine device 10 can comprise a housing 10, an inlet 11 opening and an outlet 12 opening for a flow passage therethrough. On the inlet 11 side of the turbine device 10, a flange or branch piece or part 100 can be mounted / arranged to or threaded into the inlet 11 opening of the turbine device housing 10. The flange or branch part 100 can be angled, depending on the river conditions and/or on the desired water intake. Branches 100 with different angles (3 (beta) can be used depending on actual and/or desired conditions and/or requirements (see figure 6A). A water intake pipe 110 with predetermined length(s) L1and/or L2can be mounted / arranged /
assembled to or threaded onto or into the (angled) branch piece 100. Alternatively, the water intake pipe 110 can be mounted / arranged / assembled directly to or threaded directly onto or into the inlet 11 side or opening of the turbine device housing 10. A grid or lattice arrangement 116 may be arranged or mounted at the water intake end of the water intake pipe 110. When a water intake pipe 110 is not needed, the grid or lattice 116 can be arranged or assembled directly on the inlet 11 side or opening of the turbine device 10 (see figure 3D). The grid or lattice
arrangement 116 may prevent loose objects from entering into the turbine device 10, such as, e.g., large fish, tree branches, brushes, etc. Additionally or alternatively, the grid or lattice arrangement 116 can cut up and guide the water flows with turbulence, and the water comes out from the outlet side 12 and back to free outside water flow as soon as possible. The lattice or grid 116 may e.g. be comprised of vertical and/or horizontal metal or steel plates or poles or wires or rods håving a spacing or opening of e.g. about 5 - 20 cm therebetween, but not limited thereto. The lattice or grid 116 (and particularly the front part facing the water flow) may be mounted at an angle a (alfa) with respect to the water flow in order to direct floating objects away from and/or over the turbine device 10 and/or system 1 (see figure 3D). The outer edges of the lattice or grid 116, when mounted directly on the inlet 11 side or opening of the turbine device 10, may also serve to guide or direct or carry the water flow or stream 40 in towards a turbine 50 and its blades 52 in the turbine device 10.
A rear lattice or grid (not shown) can be arranged on the outlet 12 side or opening of the turbine device 10, at which side 12 the water flow or stream exits the turbine device 10, i.e. at the downstream edge of the turbine device 10 and system 1. This rear lattice or grid may be arranged or mounted, so as to cut water or current vortexes downstream of the turbine device 10 and system 1 and to thus return the water more quickly into the river.
A cleaning knife or fork (not shown) can be arranged on the lattice or grid arrangement in order to dean and take away objects. The cleaning knife or fork can be connected to a rope or wire (not shown) that can be manipulated from land or from the top or water surface.
Furthermore, near the water intake end of the water intake pipe 110, two wings or spoilers 115 håving rudders can be symmetrically arranged on the water intake pipe 110 in order to stabilize the water intake pipe 110 in the water and to be able to (mechanically) adjust the water intake pipe 110 with respect to the river current and/or to (mechanically) adjust the height of the water intake pipe 110 end with respect to the intake 11 side of the turbine device 10. The two wings or spoilers 115 of the water intake pipe 110 are preventing it from breaking due to the water power or forces.
Additionally, on top of the housing 10 of the turbine device 10, an air intake tube or pipe 17 can be arranged. The air intake tube or pipe 17 can be connected to the flow passage 20, 30 within the housing 10 in order to for example facilitate and/or contribute against turbulence and/or other negative impact(s) or effect(s) on the water flow.
The turbine device 10 can comprise a cover on its top side for easy access to the components or parts inside.
On top of the turbine device 10 at least one eye or lifting ring or lug or hook (not shown) can be arranged in order to ease the lifting of the structure by a crane or a helicopter.
A rod or post 15, which can be telescopic, can be arranged on top of the housing 10 of the turbine device 10 in order to provide for delivery of the generated or produced electricity / electrical energy to land by means of a cable 16. Alternatively the cable 16 can go on the river bottom or floor 200 or can be buried or dug thereunder. ln this case, the cable can e.g. be placed within a protective pipe or hose (not shown). Figure 1B is the same as figure 1 A, but it shows some components within the turbine device 10, such as the turbine 50 with its blades 52 and the flow passage portion 20. Figures 2A-2C show different embodiments of the system 1 with the turbine device 10 according to the present invention.
On figures 2A-2B, the turbine device 10 is supplied or provided with a top 19' and a bottom 19" ballast or floatation device, such as e.g. a floating pontoon, for stabilizing the turbine device 10.
The embodiment of the systeml, shown on figure 2B, comprises, instead of the water intake pipe 110, a funnel device 111 mounted / arranged / assembled to or threaded onto or into the branch piece 100 and adapted for intake of more water.
As shown on figure 2C, the turbine device 10, according to another embodiment of the system 1, may be mounted on and/or within a pipe 1000, or a certain section or portion of the pipe 1000 can be replaced with the turbine device 10.
Figures 3A-3D illustrate, in more detail, different views and/or (cross-)sections of some turbine devices 10 of the system 1 according to the present invention.
The turbine device 10 comprises a housing 10. A turbine 50 is arranged in the turbine device 10. A turbine 50 is arranged in the housing 10 of the turbine device 10. The turbine 50 comprises a shaft or axle 51 supported in the housing 10 by means of bearings (not shown). In one embodiment, the turbine shaft 51 can be vertical. The housing 10 of the turbine device 10 has an inlet opening or side 11 and an outlet opening or side 12, as well as a flow passage 20, 30 therethrough. The flow passage 20, 30 stretches or extends from the inlet opening 11 to the outlet opening 12. The turbine 50 should be arranged in the housing 10 in such a way or manner that only 60% or less of the production area thereof (which in one embodiment can be the blades 52 of the turbine 50) is arranged in the flow passage 20, 30, i.e. is exposed to the water flow or movement 40 going through the passage 20, 30. In one embodiment, 50% or less of the production area of the turbine 50 can be arranged in the flow passage 20, 30, i.e. can be exposed to the water flow or movement 40 going through the passage 20, 30. On the inlet side 11 of the flow passage portion 20 in the housing 10, a flow control device 25 can be arranged in order to alter or change the exposure of the production area of the turbine 50 from approximately 60% to almost
0% in accordance with / depending on at least one of: the current velocity / speed and the desired electrical energy production.
The housing 10 of the turbine device 10 can be quadrangular or tubular, but not limited to only these shapes. The inlet 11 and outlet 12 openings can be tubular, but not limited only thereto. The flow passage 20, 30 can be tubular, but not limited only thereto.
The area 80, 81, 82 in the housing 10, not constituting the flow passage 20, 30, can be arranged to constitute at least one and preferably several chambers or technical rooms 80, 81, 82. Some or all of the chambers or technical rooms 80, 81, 82 can be watertight / waterproof.
A gear or gear box, or belt or chain drive 91 with gearwheels 92, 93, a generator or dynamo 60, a current converter 70 and optionally other technical installations / assemblies / components / cables can be enclosed and/or sealed within at least one chamber ortechnical room 80, 81, 82 in the housing 10 of the turbine device 10.
When a belt or chain drive 91 with gearwheels 92, 93 is used (see figures 3B and 4A-4C), the shafts or axles 51, 61 of respectively the turbine 50 and the generator or dynamo 60 can be connected with a gearwheel or reduction factor being for example 1:10, but not limited only thereto. The gear or gearwheel factor can depend on the stream / current velocity / speed. In one embodiment, the shafts 51, 61 of respectively the turbine 50 and the generator or dynamo 60 can be vertically orientated.
In a further embodiment, the generator 60 can be a generator comprising permanent magnets. Additionally, the generator or dynamo 60 can be mounted directly onto the turbine 50 shaft or axle 51 without the use of gear (arrangement).
In the flow passage 20, 30, the cross-sectional area 11 at the inlet opening 11 can be bigger than the cross-sectional area 18 just before the turbine 50, thus providing for a constriction or narrowing of the water flow 40 in the passage 20. In this manner, speed increase of and/or pressure increase of the water flow 40 in the passage 20, 30, just before the turbine 50, is being achieved. This constriction or narrowing portion 20 of the flow passage 20, 30 can be bottleneck-shaped or conical. However, other forms of the narrowing or inlet portion 20 of the passage 20, 30 can be possible. The flow control device 25 can be arranged in this narrowing portion 20. In another embodiment, the flow control device 25 can constitute said constriction or narrowing in that portion 20 of the flow passage 20, 30, for example at least one wall thereof.
At least one ballast or floatation device 90', 90" (see figures 2A-2B), such as e.g. a floating or ballast pontoon or tank, can be arranged on the top of and/or on the bottom of and/or on at least one side of the turbine device 10. Additionally or alternatively, at least one of said chambers ortechnical rooms 80, 81, 82 can serve as a ballast or floatation device.
The turbine device or arrangement 10 can be anchored or moored to the bottom 200 of the river. For this, the housing 10 of the turbine device or arrangement 10 can comprise at least one vertical hole 13 (e.g. four holes 13 in each corner region of the turbine device 10) for guiding therethrough a mooring cable / wire and/or chain. Alternatively, said at least one hole 13 can be screwed or threaded, so that a threaded pillar 14 can be screwed therethrough 13 and then moored or anchored into the river bottom orfloor200 (see figures 1A-1B and 3C-3D).
Figures 4A-4C show, in more detail, different views and/or (cross-)sections of another embodiment of the turbine device 10 of the system 1 according to the present invention.
In this another embodiment of the turbine device 10, the flow control device 25 comprises only one wing or flipper device 25, while in the embodiment shown on figure 3A the flow control device 25 comprises two wing or flipper devices 25, being arranged or adapted for altering or changing the exposure of the production area of the turbine 50 from approximately 60% to almost 0%. In addition, the turbine device 10 can comprise less chambers ortechnical rooms 80, 82.
As further shown in figure 4A, the wing or flipper of the flow control device 25 can comprise several profiles 25' for cutting the water flow 40 e.g. in order to reduce turbulence. Said water flow cutting profiles 25' can be arranged on and be substantially perpendicular to the working side or profile or (sur)face or plane of the wing or flipper (device) 25. With the "working" side or face of the wing or flipper device 25 we can understand this side or surface of the wing or flipper 25 that is exposed to the water flow 40.
On figure 4C the wing or flipper device 25 of the flow control device 25 is illustrated in a different position.
Furthermore, it is shown that depending on the conditions and/or the requirements, on the inlet 11 side of the turbine device 10 there can be arranged one of: a branch or flange piece or part 100 (see e.g. figures 1A-1B, 2A-2B, 7A-7B), a water intake pipe 110 and a grid or lattice arrangement 116 (see figure 3D and also figures 5A-5B, 6B).
Figures 7A-7B show another embodiment of the flange or branch piece or part 100 that is straight / longitudinal and not angled (see also figure 3C). In this case, then, if desired, the water intake pipe 110 can be angled håving a desired angle p (beta). The angled water intake pipe can be mounted / arranged to or threaded into or onto the straight flange or branch piece or part. The angled pipes 110 or branches 100 can have rounded or sharp edges in the angled region.
While the present invention has been described in connection with the preferred embodiments of the various figures, it is to be understood that other similar embodiments may be used, or modifications or additions may be made to the described embodiments for performing the same function of the present invention without deviating therefrom. Therefore, the present invention should not be limited to any single embodiment, but rather construed in breadth and scope in accordance with the recitation of the appended claims.
