"A Multi-Functional Hydrokinetic Turbine"
Summary
5 The present invention relates to an adaptable multi-functional hydrokinetic turbine. In particular, it relates to a multi-functional hydrokinetic turbine comprising a plurality of flow catching members pivotably mounted on an endless belt.
Introduction
10
In recent times, there has been increasing interest in generating electricity from sustainable sources, both as a means of reducing carbon emissions and a means of reducing society's dependency on fossil fuels. Such sustainable sources of electricity include wind energy, solar energy and water energy. Water energy can be considered to 15 be energy captured from waves, tidal, river and canal flows.
Devices for capturing the energy of river currents are well known, e.g. Water Wheels, Francis Turbines, and Archimedean Screw turbines. Such devices required large flows of water or medium to high heads.
20
In recent times Hydrokinetic Turbines (an integrated turbine electricity generator) have been developed, that do not require water flow diversion, dam creation or high heads and are suitable for use in streams and rivers. However debris in such low volume and low head water can cause numerous problems for Hydrokinetic Turbines, especially 25 debris that can block the water intake area reducing the volume of water passing through turbines, debris can also become entangled in the workings of machines which slows them down or worst case causes component failures.
It is an objective therefore of the present invention to provide a multi-functional 30 hydrokinetic turbine that overcomes at least some of the above-mentioned problems.

10 Referring to the drawings, and initially to Figs. 1 and 2 thereof, there is shown a multifunctional hydrokinetic turbine indicated generally by the reference numeral 100, comprising a plastic modular belt 103 mounted on plastic cogs 109 mounted on a drive shaft 105 and idle shafts 105b, fixed to a frame 114a & 114b by means of bearings. It will be appreciated that although three shafts are indicated in this embodiment of the 15 invention, other embodiments may use a different number of shafts. Although a simple steel plate frame 114a & 114b is shown, it will be appreciated that any suitable frame alternative may be used, including for example a lattice frame. Although this embodiment uses a plastic modular belt, it will be appreciated that other embodiments may use belts or chains may be used in its place. Bracing 113 is fixed to the frame pieces 114a and 20 114b to ensure the structure is rigid.
The direction of water flow through the turbine 100 is indicated by the arrow 104. Flowing water 104 passes through a head-opening 117 at a lower part of the front end of the turbine 100 and exits the turbine at a tail-opening 118 at an opposite end thereof. 25 Although this embodiment is shown without a bottom panel to the machine, it will be appreciated that a bottom panel may be included to control water through the machine.
Fins made of metal, plastic or timber 101 are attached to the modular plastic belt 103 by means of a hinge joint 119. Water 104 moving through the machine in the direction of 30 the arrow indicated forces the fins 101 in the direction of the water 104. The fins 101 mode the plastic modular belt 103 in the direction indicated by the arrows 110. The blades 101a rotate to be flat to the plastic modular belt 103 when returning to the starting point 117.
-7-
The plastic modular belt rotates the drive shaft 105, the drive shaft 105 turns a timing belt 115 and the timing belt 115 rotates the generator 116. Although one generator is show in this embodiment, it will be appreciated that a different number of generators may be mounted on the machine. In one such example the idle shafts 105b may be used to 5 drive generators.
Guides made of metal, plastic or timber 111 are used to ensure that the plastic modular belt 103 runs in a straight line. The fins 101 are prevented from over opening by means of a stay support 120. The stay support 120 will have a means of allowing the fin to over
10 open in high water speeds to prevent damage to the machine. Although a piston type stay is indicated in this embodiment, it will be appreciated that a different number of methods may be employed; an example of an alternative method would be the use of chains or ropes with springs to allow over extension in high water speeds.
15 Fig. 3a. shows a partial view of the machine 100. Debris 121 is being forced toward the machine by the water 104. As the debris 121 approaches the machine 100 the debris 121 is forced downward by the debris guard 106.
In Fig. 3b. the debris has be forced through the front opening 117 and is caught by the
20 next rotating fin 105c. The fin 105c is pulled around by the rotation of the plastic modular belt 103, moving the debris 121 through the machine 100. If the debris 121 is large as indicated in Fig 3c the fin 105d will remain partially closed as the debris 121 moves though the machine 100.
25 Fig 4 shows a second embodiment of the machine. In this embodiment the frames 214a and 214b are constructed from a welded framework with sheet metal cladding. The workings of the turbine are enclosed by the cover pieces 212 & 212a. The generator is housed in the housing 208 with the lid 202.
30 Fig. 5 shows the same perspective view as Fig. 4, with the cover and frame pieces removed to expose the workings of the machine. This embodiment of the invention indicates an alternative fin 201 to the fin 101 shown in Fig. 1. The fin 201 is fixed to the plastic modular belt 203 with a hinge 225. The fin 201 is designed with a flat section that opens against the plastic modular belt 203 to prevent the fin from over opening.
-8-
In these embodiments the water 104 moves through the machine in the direction of the arrow, catches the fins 201 which moves the plastic modular belt 203 in the direction of the arrows 210. The plastic modular belt 203 rotates the drive shaft 205, which rotates 5 the generator 216 by means of the pulley 222 , the belt 221 and the pulley 222a. The pulleys 222 & 222a are geared to proved the appropriate torque and speed to the generator.
Although these embodiments of the invention show pulleys and belts between the drive 10 shaft and the generator, it will be appreciated that other embodiments of the invention may use a generator that is mounted directly on the drive shaft and rotated directly by the drive shaft or by means of geared cogs.
Referring to Fig. 6 which indicates various embodiments of the invention. The machine 15 300a is mounted on two floats 350. The machine 300b is mounted on a dam or weir 351. The machine 300c is mounted vertically on a waterfall 352. In another embodiment the machine 300a would be sitting on the river bed, completely submerged below the water 304.
20 Fig. 7a shows a partial perspective view of an embodiment of the fins 401 in their closed position and the endless belt comprising plastic modules 403. The fins 401 have rotated along the path of the arrow 430 to be in their closed position flat against the endless belt 403 which is moving in the direction of the arrow 350. In this embodiment the supports 429 and the restraints 420 can be seen in their closed position. Although a shape for the 25 supports has been indicated, it will be appreciates that the supports made be of a different shape and design, for example the supports may be a more aerodynamic design to reduce friction with air or water. Fig 7a shows a modular belt module 403a with an additional hinge point for attaching the fins 401 and the supports 429.
30 Fig 7b shows a partial perspective view of an embodiment of the fins 401 in their open position and the endless belt comprising plastic modules 403. The force is moving the fins 401 and the endless belt 403 in the direction of the arrow 451. The fin 401 has rotated through 90 degrees along the path of the arrow 431 to be perpendicular to the endless belt 403. In this embodiment the restraints 420 and the supports 429 have also
-9-
moved into their open position, with the supports 429 flat against the soffit of the belt 403.
In these embodiments can be seen an embodiment of the fins 401 which are made from 5 moulded plastic. The fins 401 show a design for the distal end of the fins 401 with a groove 460. Fig. 8. Shows the fin 401 in different locations as the belt moves in the direction of the arrows 110. The fin 401 a is in the closed position flat against the endless belt 403. The fin 401b is further along and has started to open by rotating in the direction of the arrow 432. Fin 401c has opened to meet the surface of the water 104a. The fin 10 401c is design such that the distal end with the groove 460a breaks the surface of the water 104a, at which point the force of the water moving in the direction of the arrow 404 opening the fin 401 d to be perpendicular to the endless belt 403. The fin 401 d is prevented from opening to far by the restraint 420 and the support 429. The fin 401 d is pushed by the force of the water in the direction of the arrow 404 to the position of the fin 15 401 e, this motion rotates the cogs 409 and drive shaft 405.
Fig. 9 shows embodiment of a fin 501 in it's working position attached to a triple hinged modular belt unit 503a which is in turn connected to further modular belt units to form the endless belt 503. Water flowing in the direction of the arrow 504 forces the fin 501 which 20 pulls the belt 503 in the direction of the arrow 504. The support 529 and the piston 520 prevent the fin from opening past its ideal working position except in times of forces of water greater than required to turn the invention for maximum production. At such times the piston contracts in the direction of the arrow 525, thus reducing the depth of the fin 501 in the water which maintains the force moving through the machine.
25
Fig. 10 shows a further embodiment of a fin 601 in it's working position attached to a triple hinged modular belt unit 603a which is in turn connected to further modular belt units to form the endless belt 603. Water flowing in the direction of the arrow 604 forces the fin 601 which pulls the belt 603 in the direction of the arrow 604. In this embodiment 30 chains 630 and 630a with a spring 631 attached at one end to the belt 603 and the other end to the fin 601. The chains 630 and 630a and the spring 631 prevent the fin from opening past its ideal working position except in times of forces of water greater than required to turn the invention for maximum production. At such times the spring expands
- 10-
in the direction of the arrows 632, thus reducing the depth of the fin 601 in the water which maintains the force moving through the machine.
In use the hydroelectric turbine 100 is placed into a flowing stream 200 millimetres deep 5 and a flow rate of 1.6 metres per second. Electricity was generated at a rate of 720 watts even after challenging the turbine with sticks, weeds and general flotsam.
