Description

FLOATING WATER TURBINE FOR POWER GENERATION USING CANAL/RIVER WATER FLOW OR LASHING SEA WAVES.
There have been many proposals to generate electricity in the flowing water of the canals, rivers, sea waves. The potential energy possessed in the flowing water are not used for large scale commercial power production, because the conventional water turbines are not suitable for tapping the maximum potential energy/force of the moving water column or the lashing sea waves and also .the installation and maintaining those turbine and generator in the flowing water is a difficult task.
The aquatic source of renewable energy is not as popular as the other sources of renewable energy such as the solar and wind energy. This is because of no suitable type of water turbine is available, which can tap maximum potential energy of the flowing water and capable of using for mass production of electricity and easy to install and maintain in/on the flowing water.
The conventional underwater turbines have fan like blades as its turbine blades. These blades are aerodynamically shaped and rotated by the aerodynamic forces LIFT and DRAG which are generated when the flowing water embraces the turbine blades. Only a small portion of flowing water embraces these blades. Most portion of water flowing with in the turbine area / diameter is wasted as it passes through the inter blade area and do not register any force on the blades. That is why the conventional underwater turbines are less productive. Mainly for these reasons, these type turbines are not used for mass production of electricity and projects like ‘wind park’ arrangements. Because of these reasons the aquatic source of energy is not familiar and not used for commercial scale of electricity production.
The flowing water posses a thrusting force in it. The conventional blades do not registers the thrusting force directly. The necessity to invent a suitable turbine with high productivity is always exists.
These problems are overcome by the present invention which provides the opportunity to register the maximum thrusting force of the moving water column or the lashing sea waves. In this invention a water turbine is designed in a novel way as to register the thrusting force directly and register maximum force embedded at any cross section of the flowing water in river, canal and lashing sea waves and converting the registered force in to torque. The present invention also makes the installation and maintenance of turbine/generator on the flowing water made easy. This invention is a further development or modification of the previous invention patented by the same inventor.
The specialities and novelties of this invention are
1. The generator/altemator is an in-built structure of a water sealed capsule like body. So there is no threat to the generating part by the water or moisture.
2. In this invention, there is no visible separation of turbine part and gearing part and generator part. Everything are enclosed with in a capsule like structure.
3. It is perfectly floatable on the surface of the flowing water. If the flowing water raises, the instrument will not dip in to the water, due to floatability or buoyancy.
4. It is easily portable and it can be moved to any place without dismantling the parts/portions.
5. There is no need for any civil construction in or outside the water column.
6. It is constructed with simple materials.
7 At the time of installation we need not assemble the various parts or potions.
8. An array of such turbines can be placed continuously with little distance on the flowing water surface to any length the flowing water column.
9 There is no need for synchronization of parts from time to time.
10. There is no external moving parts. So, the maintenance is easy.
According to the invention, there is provided a FLOATING WATER TURBINE FOR POWER GENERATION USING CANAL/RIVER WATER FLOW OR LASHING SEA WAVES is comprising of, a FLOATABLE HORIZONTAL CYLINDRICAL BODY (no. l) which is the outer body, in side which there are two VERTICAL WALLS (no.3) rigidly fixed with the inner surface of the FLOATABLE HORIZONTAL CYLINDRICAL BODY (no. l). A TUBULAR CENTRAL AXIS (no.2) is the central axis of the instrument. Two CANTILEVER TUBULAR HOLDERS (no.4) fixed at the centre of the VERTICAL WALLS (no.3) capable of carrying the TUBULAR CENTRAL AXIS (no.2) in rotatable position. Set/s of BEARINGS (no.9) used for easy rotation of the rotatable parts. WATER SEALS (no.9 A) are used to make the device leak proof. A LEVERAGE WEIGHT CARRIER (no.7) is a vertical plate/rod in single or in multiple number, rigidly attached with the TUBULAR CENTRAL AXIS (no.2) and hanging downwards. An ALTERNATOR /GENERATOR/DYNAMO (no.8) is attached at the extreme lateral end of the LEVERAGE WEIGHT CARRIER (no.7) and also acting as the leverage weight. A set of GEARS (nos.5,6) of which the largest GEAR (no.6) is attached on the inner side surface of the VERTICAL WALL/S (no.3) and the smallest GEAR (no.5) attached with the ALTERNATOR (no.8) and such GEARS (nos.5,6) intended to multiply the rotations and transfer the force registered by the PADDLES (no.1 1) to the ALTERNATOR (no.8). PEDDLES (no.1 1 ) are fixed at the outer surface of the HORIZONTAL CYLINDRICAL BODY (no.l) and pointing outwards and in parallel to this outer body, are intended to register the thrusting force of the moving water column. A MOORING HOOK (no.l2)/projection at the front of the HORIZONTAL CYLINDRICAL BODY (no. l), is meant to be connected to the MOORING ARRANGEMENTS (no. l2A). A WIRE DRAWING PIPE (no.10) attached to one end of TUBULAR CENTRAL AXIS (no.2), is meant to draw the wires from the ALTERNATOR (no.8) through the inner hole of the TUBULAR CENTRAL AXIS (no.2).
There now follows a description of some particular embodiments of this invention, by way of examples only with reference to the drawings in which
The figure 1 shows the example of the longitudinal cross section of the assembly/arrangement of various parts of the turbine symbolically.
The figure 2 shows the example of the external view of the turbine which is having horizontal PADDLES (no. l l).
The figure 3 shows the example of the external view of the turbine which is having screw like paddles / spiral PADDLES (no. l l).
A HORIZONTAL CYLINDRICAL BODY (no. l) is the outer most cover which is enclosing most of the parts. VERTICAL WALLS (no.3) are rigidly and vertically fixed at the inner surface of the HORIZONTAL CYLINDRICAL BODY (no. l). Two CANTILEVER TUBULAR HOLDERS (no.4), each one is rigidly fixed at the centre of the each VERTICAL WALL (no.3) and pointing inwards, intended to hold the TUBULAR CENTRAL AXIS (no.2) at its centre and allow it to roll freely with the help of BEARINGS (no.9). The TUBULAR CENTRAL AXIS (no.2) is freely roll able inside of the CANTILEVER TUBULAR HOLDER (no.4) with or without the help of BEARINGS (no.9), spindling independent of CANTILEVER TUBULAR HOLDER (no.4). A LEVERAGE WEIGHT CARRIER (no.7) is rigidly fixed with the TUBULAR CENTRAL AXIS (no.2) in a hanging position, is meant to keep the TUBULAR CENTRAL AXIS (no.2) at a static position while the outer body with other attachments are inn rotational motion and also to carry the ALTERNATOR (no.8).
The ALTERNATOR (no.8) is attached at the lateral end of LEVERAGE WEIGHT CARRIER (no.7). A smallest GEAR (no.5) is attached with the ALTERNATOR (no.8). A counter gear which is the largest GEAR (no.6) is rigidly attached over the inner side surface of the Vertical walls (no.3), is meant to transfer the force registered at the PADDLES (no.1 1 ) which are rigidly attached with the HORIZONTAL CYLINDRICAL BODY (no.1 ), and transfer such force to the ALTERNATOR (no.8).
One end of the TUBULAR CENTRAL AXIS (no.2) is extended outside the HORIZONTAL CYLINDRICAL BODY (no.1) and a WIRE DRAWING TUBE (no.10) is attached at this end, pointing upside, is meant to draw out the wires from the ALTERNATOR (no.8) through the inner hole of the TUBULAR CENTRAL AXIS (no.2). The PADDLES (no.1 1) in multiple are attached over the outer surface of the HORIZONTAL CYLINDRICAL BODY (no. l ) in parallel and pointing laterally. A freely turn able MOORING HOOK (no.12) is attached at the one end of the HORIZONTAL CYLINDRICAL BODY (no. l) is meant to be attached with the MOORING ARRANGEMENTS (no. l2A) and facilitate the whole instrument turn able freely while floating. The water SEALS (no.9A) are attached at necessary places, meant to protect the instrument and avoid seepage of water inside the whole body.
The following is the way of performing of this innovative instrument:
The apparatus described above is laid to float on the flowing water with mooring arrangements. The flowing water which is possessing a thrusting force, do push the PADDLES (no.1 1 ). The PADDLES (no. l l ) which are attached with the HORIZONTAL CYLINDRICAL BODY (no. l) and both are rotated. The VERTICAL WALLS (no.3) which are attached with the inner surface of the outer body also get rotated and the large GEAR (no.6) which is attached with the VERTICAL WALL/S (no.3) also rotated and this in turn rotates the counter small GEAR (no.5) which is attached with the alternator. Thus the alternator get rotated and produces electricity. The alternator attached at the lateral end of the LEVERAGE WEIGHT CARRIER (no.7) which is attached with the TUBULAR CENTRAL AXIS (no.2) do not turn due to gravity pull, while the HORIZONTAL CYLINDRICAL BODY (no.l) with attached larger GEAR (no.6) turns in one direction. The down pulling (gravity) of alternator’s weight/other dead weights keeps the TUBULAR CENTRAL AXIS (no.2) at a static position and while the larger GEAR (no.6) with the outer body is in rotational motion.
