Description

A HYDROKINETIC INSTALLATION FOR
GENERATING ELECTRICTY
This invention relates to a hydrokinetic installation for generating electricity.
Installations for generating electricity from water are well known. Typically the water is used to drive electricity generating means such for example as a turbine. Often the installations are not conveniently located. Also, operational efficiency may be adversely compromised by slow water speeds.
It is an aim of the present invention to reduce the above mentioned problems.
Accordingly, in one non-limiting embodiment of the present invention there is provided a hydrokinetic installation for generating electricity, which hydrokinetic installation comprises: (i) a first chamber for receiving water; (ii) an inlet for enabling water to enter the first chamber; (iii) an outlet for enabling water to leave the first chamber; (iv) a second chamber for receiving water; (v) a pontoon which floats on water in the second chamber; (vi) a connecting formation which connects the first chamber to the pontoon; (vii) electricity generating means on the pontoon; and (viii) a vortex formation, and the hydrokinetic installation being such that: (ix) the connecting formation is for receiving water from the outlet of the first chamber and for directing the water to the vortex formation; (x) the vortex formation is for increasing the velocity of the water and for providing the increased velocity water for the electricity generating means; (xi) the electricity generating means is operated by the increased velocity water and thereby generates the electricity; water from the electricity generating means passes to the second chamber, (xiii) the pontoon varies in height with respect to the first chamber in dependence upon the height of the water in the second chamber; and (xiv) the connecting formation is able to maintain the connection between the outlet from the first chamber and the pontoon irrespective of the height of the pontoon with respect to the first chamber.
The hydrokinetic installation of the present invention is advantageous in that it is easily able to be installed on rivers or other places where there is a required supply of water. The hydrokinetic installation is able to generate electricity as and when required by enabling the water in the first chamber to pass through the outlet and to the second chamber. The hydrokinetic installation of the present invention may be especially advantageous for use on rivers where it is desired to increase use of a part of a river, for example by boats and house boats requiring electricity. The hydrokinetic installation can be operated as and when desired to provide the required electricity in a simple and efficient manner. This in turn encourages users to use the hydrokinetic installation, which in turn causes users to frequent the vicinity of the hydrokinetic installation. Thus hitherto unused or under-use river locations may increase in popularity for use by river users. The electricity can be used for providing power for whatever electrically-operated apparatus the vessels require and/or the electricity can be used for generating hydrogen for vessels which may be hydrogen powered.
The hydrokinetic installation is also advantageous in that the use of the pontoon avoids the need for extensive and intrusive civil engineering at the installation site. The pontoon may be a modular enabling device giving uniformity of design and flexibility. The pontoon may be scaled up as required to take larger electricity generating means, for example larger turbines, which will require a greater water flow and more weight of water.
The hydrokinetic installation may be one in which the connecting formation comprises a hinge formation which enables the connecting formation to maintain the connection between the outlet from the first chamber and the pontoon irrespective of the height of the pontoon with respect to the first chamber. Connecting formations other than a hinge formation may be employed.
When the connecting formation is a hinge formation, then the hinge formation is preferably positioned at an end of the connecting formation nearest the pontoon. Other positions for the hinge formation may however be employed so that, for example, the hinge formation may be positioned at an end of the connecting formation nearest the first chamber.
The hydrokinetic installation is preferably one in which the vortex formation is on the pontoon. However, if desired, the vortex formation may be positioned elsewhere as long as it is able to provide the increased velocity water to the electricity generating means.
Preferably, the vortex formation is vertically mounted on the electricity generating means and such that the vortex formation has a longitudinal axis which is vertical with respect to the water in the second chamber. Other angles of inclination for the vortex formation may be employed so long as the vortex formation is able to provide the increased velocity water to the electricity generating means.
The vortex formation may be made of concrete. The vortex formation may be made of other materials if desired, for example metals.
The hydrokinetic installation may include sluice means for opening and closing the inlet and the outlet for the first chamber.
The sluice means may comprise a first sluice arrangement for the inlet and a second inlet sluice arrangement for the outlet. The first sluice arrangement may operate a first baffle for the inlet. The second sluice arrangement may operate a second baffle for the outlet. Other types of sluice arrangement may be employed. The sluice arrangement may be manually and/or electrically operated.
The hydrokinetic installation may be one in which the second chamber is constructed such that water from the electricity generating means that is not required is emptied from the second chamber by flowing over a wall of the second chamber. The wall may be such that it maintains a predetermined height of water in the second chamber.
The electricity generating means will typically be a turbine. The electricity generating means, for example the turbine, may employ a rotor and a stator. Other types of electricity generating means may be employed.
The hydrokinetic installation may include control means for controlling the operation of the hydrokinetic installation. The control means may be a computer controlled control means. The control means may enable the hydrokinetic apparatus to be fully automatic in operation, for example on a continuous basis or as and when required by a user.
The hydrokinetic installation may include a base foundation for ensuring a known depth of water in the first chamber and a known depth of water in the second chamber. The base foundation may be mounted on piles. The base foundation may be made of concrete or any other suitable and appropriate material. The piles may be made of concrete or any other suitable and appropriate material, for example iron or steel.
The hydrokinetic installation may include inverter means for converting the electricity generated by the electricity generating means from AC to DC, for example for the convenience of use by users of waterborne vessels.
The hydrokinetic installation may include storage means for storing the generated electricity. The storage means will typically be a battery or a bank of batteries. Other types of storage means for storing the generated electricity may be employed.
The hydrokinetic installation of the present invention may be constructed to provide power for waterborne vessels which are powered by hydrogen. More specifically, the hydrokinetic installation may then include conversion means for converting the electricity into hydrogen. The conversion means is preferably an electrolyser but other types of conversion means may be employed.
Preferably, the hydrokinetic installation is constructed for installation in a river. The hydrokinetic installation may however be constructed for use in other locations where there is an appropriate supply of water, for example a tidal location in a sea or an estuary.
Embodiments of the invention will now be described solely by way of example and with reference to the accompanying drawings in which: Figure 1 is a schematic side view of a hydrokinetic installation for generating electricity as installed and operated with a normal water level; and Figure 2 is a view like Figure 1 but shows the hydrokinetic installation of Figure 1 in operation with a raised water level.
Referring to the drawings, there is shown a hydrokinetic installation 2 for generating electricity. The hydrokinetic installation 2 comprise a first chamber 4 for receiving water 6. An inlet 8 enables water 10 from a river to enter the first chamber 4. An outlet 12 enables the water 6 to leave the first chamber 4.
The hydrokinetic installation 2 includes a second chamber 14 for receiving the water 6. A pontoon 16 floats on water 18 in the second chamber 14.
A connecting formation 20 connects the first chamber 4 to the pontoon 16. As shown in Figure 1, the connecting formation 22 acts as a ramp.
The hydrokinetic installation 2 includes electricity generating means 22 on the pontoon 16. The hydrokinetic installation 2 also includes a vortex formation 24.
The hydrokinetic installation 2 is such that the connecting formation 20 is for receiving water 6 from the outlet 12 of the first chamber 4 and for directing the water 6 to the vortex formation 24.
The vortex formation 24 is for increasing the velocity of the water 6 and for providing the increased velocity water 6 for the electricity generating means 22. The electricity generating means 22 is operated by the increased velocity water 6 and thereby generates the electricity.
Water from the electricity generating means 22 passes to the second chamber 14. The pontoon 16 varies in height with respect to the first chamber 4 in dependence upon the height of the water 18 in the second chamber 14.
The connecting formation 20 comprises a hinge formation to maintain the connection between the outlet 12 from the first chamber 4 and the pontoon 16 irrespective of the height of the pontoon 16 with respect to the first chamber 4. The hinge formation (not shown) is positioned at an end 26 of the connecting formation 20 nearest the pontoon 16.
The vortex formation 24 is on the pontoon 16. The vortex formation 24 is vertically mounted so that the vortex formation 24 has a longitudinal axis which is vertical with respect to the water 18 in the second chamber 14. The vortex formation 24 comprises a spiral passage 28 formed between a spirally-extending wall 30. The wall 30 is made of concrete but it may be made of other materials such for example as a metal if required.
The hydrokinetic installation 2 includes sluice means 32 for opening and closing the inlet 8 and the outlet 12 for the first chamber 4. The sluice means 32 comprises a first sluice arrangement 34 for the inlet 8. This first sluice arrangement 34 comprises a baffle 36 which is raised and lowered by raising and lowering means 38.
The sluice means 32 also comprises a second sluice arrangement 40 for the outlet 12. The second sluice arrangement 40 may also be a baffle. The first and second sluice arrangements 34, 40 may be constructed similarly to sluice arrangements on known locks on rivers and canals.
The second chamber 14 is constructed such that water from the electricity generating means 22 is emptied from the second chamber 14 by flowing over a wall 42 of the second chamber 14. The wall 42 maintains a predetermined height of water 18 in the second chamber 14.
The electricity generating means 22 is a turbine. The turbine may contain a rotor (not shown) mounted in a stator (not shown). The rotor is caused to rotate and thus generate electricity by virtue of the water 4 passing along the vortex formation 24, gathering speed, and then entering the electricity generating means 22. The electricity generating means 22 may be of a known construction.
The hydrokinetic installation 2 may include control means (not shown) for controlling the operation of the hydrokinetic installation 2. The control means may be a computer controlled control means.
The hydrokinetic installation 2 includes a base foundation 44 for ensuring a known depth of the water 6 in the first chamber 4, and a known depth of water 18 in the second chamber 14. The base foundation 44 is mounted on piles 46. The piles 46 may be made of concrete or other materials such for example as iron and steel, as may be required.
The hydrokinetic installation 2 may include inverter means (not shown) for converting the electricity generated by the electricity generating means from alternating current (AC) to direct current (DC). Electricity storage means (not shown) for storing the generated electricity may be employed. The electricity storage means may be a battery or a bank of batteries. The electricity from the electricity storage means may then be used as and when required for providing electricity on demand for users.
In an optional embodiment of the present invention, the hydrokinetic installation 2 may include conversion means (not shown) for converting the electricity into hydrogen. The conversion means may be an electrolyser. The hydrogen may then be used for powering boats or other vessels that are powered by hydrogen.
The hydrokinetic installation 2 as shown in Figures 1 and 2 is constructed and installed in a river having a bank 48. The hydrokinetic installation 2 may be compared to a lock in a river or a canal. The first chamber is like a lock in a river or a canal and the first chamber 4 is bounded on one or both sides by a structure comprising steps 50 and a handrail 52. A walkway 54 over the first chamber 54 is shown in cross section.
In use, the hydrokinetic installation 2 is easily operated as and when required by users. The hydrokinetic installation 2 may be operated intermittently as and when electricity is required. Alternatively, the hydrokinetic installation 2 may be operated on a substantially continuous twenty four hour basis under the control of the electronic control means in order to ensure that electricity is always stored in a battery or batteries or other electrical storage means, and always available on demand at any time when required by users. With the electricity always being available on demand, river users will be encouraged to use the river and this may provide increased use of the river, which may itself lead to increased busines in the vicinity.
If the hydrokinetic installation 2 is computer controlled, then the computer will be able to know the optimum height of the pontoon 16 relative to the sluice means 32, and the computer will then be able to control the angle of inclination of the connecting formation 20 so that the water 6 flows into the vortex formation 24 at the required rate. Thus the computer is able to allow for the fact that the pontoon 16 is itself going up and down in dependence upon the volume of water 6 passing through the outlet 12 of the first chamber 4. Thus the computer is able to ensure that the water 6 enters the electricity generating means 22 from the vortex formation 24 always at the optimum velocity, and always whilst the hydrokinetic installation 2 is in operation.
It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. Thus, for example, other types of connecting formation 20 than the illustrated channel-type ramp may he employed. Similarly, other types of base foundations 44 and control means may be employed. The pontoon 16 may be of other shapes. The vortex formation 24 may be of other shapes and it may be positioned elsewhere on the pontoon, or off the pontoon providing the vortex forrnation 24 is still able to provide the increased velocity water 6 to the electricity generating means 22. The water 18 that leaves the second chamber 14 is able to flow over the wall 42 and into a flood channel 56. The flood channel 56 typically leads back to the river downstream of the hydraulic installation 2. Individual components shown in the drawings are not limited to use in their drawings and they may be used in other drawings and in all aspects of the invention. The invention also extends to the individual components mentioned and/or shown above, taken singly or in any combination.
