Description

AN APPARATUS FOR UTILIZING WATER MOVEMENT ENERGY
FIELD OF THE INVENTION
This invention relates to an apparatus for utilizing water movement energy to generate electricity. The apparatus is thus useful to produce electric energy by taping the energy intrinsic in water movement in canals, rivers, seas and oceans to generate electricity.
STATE OF THE ART IN THE FIELD
It is known to generate electricity by using turbines and / or windmills type devices immersed in sea water for tapping intrinsic energy in water currents. One of the device comprises a wind mill type turbine adapted to be installed on the sea bed. These turbines are rotated by flowing water and thus provide drive to an alternator used to generate electricity. Another device known in prior art is to employ different types of blade configurations mounted on rotor shafts vertically or horizontally such as to obtain drive as the blades rotate. Another device known in the art is to generate electricity from the water currents comprises turbines embedded inside circular cages. Yet another method adopted in prior art is to erect dams at the mouth of estuaries to store water and then by creating a potential difference with difference in height tap the energy by falling the same on the turbine.
There are disadvantages associated with the known devices. One of the main disadvantages is that these devices are costly and the efficiency is very low therefore are not commercially viable. Another disadvantage associated with the known devices is that known devices do not work when the level of the water is low.
Yet another disadvantage is that water level in canals, rivers, seas and oceans keep changing and most prior art devices cannot adapt themselves to this condition. Yet another disadvantage associated with the known devices is that known devices are unable to withstand abrupt increase in energy levels of water movement.
Still another disadvantage associated with the known devices is that known devices are unable to tap energy from water streams having low depths.
OBJECT OF THE INVENTION
Therefore an object of the present invention is to provide an apparatus for utilizing water movement energy available in canals, rivers, seas, oceans, etc. which obviates the disadvantages associated with the prior art.
Another object of the invention is to provide an apparatus for utilizing water movement energy and to generate electricity in all kinds of conditions that is when the apparatus is submerged in water partially or fully.
Yet another object of the invention is to provide an apparatus for utilizing water movement energy and to generate electricity and which is cheap in cost, but has high efficiency.
Still another object of the invention is to provide an apparatus for utilizing water movement energy and to generate electricity which can work irrespective of the water level present in the river, sea and ocean in order to tap the intrinsic energy of the water movement.
STATEMENT OF THE INVENTION
According to the invention there is provided an apparatus for utilizing water movement energy comprising plurality of blade adapted to be secured with a shaft being secured with a support frame at an angle with respect to the water level available in the water resources, the support frame being mounted on a pedestal adapted to be secured with a plurality of support rods provided at angle, the angular support rods 5 being secured with a main support frame, one end of the angular shaft being coupled with a gearbox, adapted to be secured with an alternator provided for generating electricity, a cover being provided such that to create an air trap to facilitate rotation of the blades uninterruptedly.
BRIEF DESCRIPTION OF THE DRAWINGS
An apparatus for utilizing water movement energy according to a preferred embodiment is herein described and illustrated in the accompanying drawings wherein,
Fig. 1 illustrates sectional view of the apparatus of the present invention,
Fig. 2 illustrates isometric view of the apparatus of the present invention,
DETAILED DESCRIPTION OF THE EMBODIMENT OF THE INVENTION
An apparatus for utilizing water movement energy is herein described and illustrated with numerous specific details so as to provide a complete understanding of the invention. However these specific details are exemplary details and should not be treated as the limitation to the scope of the invention. The invention may be performed with slight modifications.
Referring to the drawings, figures 1 and 2, isometric view and sectional views of the apparatus of the present invention are shown. The apparatus comprises a plurality of blade 1 adapted to be secured with a shaft 2 at an angle with respect to the water level available in the water resources, for example canals, rivers, seas and oceans, so as to constitute a turbine. The angular shaft 2 is secured with a support frame 3, rotatablely. The support frame 3 is mounted on a pedestal 4 and the pedestal is adapted to be secured with a plurality of support rods 5 provided at an angle. The angular support rods 5 are adapted to be secured with a main support frame 6 provided over the support frame 3 at a desired height. The top end of the angular shaft 2 is coupled with a gearbox 7 through a coupling 8. The shaft of the gearbox 7 is adapted to be secured with an alternator (not shown) provided for generating electricity. A cover 9, adapted to be secured with the pedestal 4, is provided such that to provide an air trap at the side of the blades which are kept at a slanting height above the water level available in the water resources.
In one embodiment the blade 1 are of flat plate type blades and thus the manufacturing cost of the blades is reduced substantially. The blades 1 are secured with the angular shaft by means of riveting, welding and or nuts and volts. According to another embodiment presence of the water inside the cover 9 is reduced by increasing air pressure inside the cover 9. During the operation of the device, the water pushes the turbine blade 1 which are in contact with the water, but the blades rotates in the air trap provided inside the cover 9 at the other side without obstruction a the water is not present there. Thus the angular shaft is rotated and consequently shaft of the alternator is rotated and electricity is generated.
Certain features of the invention have been described with reference to the example embodiments. However, the description is not intended to be construed in a limiting sense. Various modifications of the example embodiments as well as other embodiments of the invention, which are apparent to the persons skilled in the art to which the invention pertains, are deemed to lie within the spirit and scope of the invention.
