Abstract

Disclosed is an invention related to an apparatus that is designed to be installed in a boat hull for generating electricity from the wave energy. Electricity is generated by the apparatus as the gearwheels fitted at the bottom of each of side a pendulum flap slides over a plurality of cogwheels. As the gearwheels moves over the plurality of cogwheels, the generator fixed at the bottom of the pendulum flap generates electricity and transports the generated electricity through the fork-shaped metal frame mounted at the center on each side of the boat hull by using roller bearings.

Description

An Apparatus for Generating Electricity Based on Movement of an

Oscillating Body System

Field of Invention

The present invention relates to a design of an apparatus for generating electricity from wave energy and more particularly about generating electricity from wave energy by using an apparatus that is designed to generate electricity based on the movement of the oscillating body system.

BACKGROUND

Currently, there are many methods employed for generating electricity from wave energy. In one of the methods, a bouy system is used to generate electricity based on the fall and rise of the waves and the generated electricity is propelled along a power cable to the shore. In another method, a water column through which the waves moves up and down causes a piston of a turbine to rotate that in turn produces electricity. In another method, waves raised through a reservoir generate hydroelectric power by allowing water to flow from the reservoir.

Though the existing method of generating electricity does not add to the pollution, there are certain draw-backs, which affect the environment. For example, the bouy system implanted below the surface of the water can produce enough noise to negatively affect the marine migration. Further, the cost of generating electricity by using these methods can be affected by the size of the waves, the distance through which the generated electricity is to be transported, the system maintenance cost or the like.

Further, there exists an apparatus wherein the generator is connected to the driveshaft connected to the bottom of the pendulum flap to generate electricity. Flowever, such apparatus does not consider the movement of the pendulum flap based on the wave energy. Hence, the generated electricity may not be in accordance to the intensity of the wave energy or size of the wave encountered by the apparatus. For example, the prior-art: FR2523654 A1 "Wave energy converter for electric power source" is constructed with a generator connected to the driveshaft and the generator generates electricity based on the movement of the gears via a gearbox. However, the prior-art does not generate the electricity in accordance to the intensity of the wave energy or size of the wave encountered by the apparatus. Further, there is no proper means to transport the electricity generated by the generator to the anchor of the boat hull.

Hence, there is a need for an apparatus that is strong, reliable, and designed with a simple construction to generate electricity from wave energy and to transport the electricity generated by the generator to the anchor of the boat hull.

SUMMARY

The present invention is related to an apparatus for generating electricity from wave energy, wherein the apparatus comprises of a boat hull with a base structure that is in contact with the water body. Further, the apparatus comprises of an oscillating body system such as a pendulum flap mounted from top of the boat hull and is fitted with a generator at the bottom. A plurality of gearwheels fitted at the bottom of each side of the pendulum flap moves over the cogwheels based on the boat hull movement. The pendulum flap must be of a substantial weight for maintaining an upright position during the movement of the boat hull. Further, the generator fitted at the bottom center of the pendulum flap generates electricity based on the size of the wave that causes movement of the boat hull. The generated electricity is transported through a fork-shaped metal frame mounted at the center on each side of the boat hull by using roller bearings.

DETAILED DESCRIPTION

In the following detailed description, a reference is made to the accompanying drawings that form a part hereof, and in which the specific embodiments that may be practiced is shown by way of illustration. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and it is to be understood that the logical, mechanical and other changes may be made without departing from the scope of the embodiments.

The following detailed description is therefore not to be taken in a limiting sense.

Referring to FIG. Ϊ, illustrates a boat hull 100, which is installed with an apparatus for generating electricity from wave energy. In an embodiment, the base structure 101 of the boat hull 100 floats on a water body in a normal position and a fork-shape metal frame 102 is mounted at the center on each side of the boat hull 101 by using roller bearings 108. The fork-shape metal frame 102 encases an anchor-cable that transports the electricity from the generator to the anchor-block.

Referring to FIGs. 2 and 3, illustrates the boat hull 100 movement on a wave form tilted in different directions. In an embodiment as the boat hull tilts while floating over a wave, a plurality of gearwheels fitted at the bottom of each side of the pendulum flap 104 is driven over the inner cogwheel 106 and outer cogwheel 107, which in turn drives the generator 110 and generates electricity. In another embodiment, the ship hull 103 can be mounted with any other oscillating body system such as a pendulum flap 104. In an embodiment, the gearwheels 105 are mounted on a horizontal driveshaft 109 upon which an electrical generator 110 is placed. In an embodiment, the generated electricity power depends on the size of the wave form.

Referring to FIG. 4, illustrates the basic working of the apparatus. As the boat hull 104 enters the wave form, the raising wave line tilts the boat hull 101 and as the boat hull tilts, the gearwheels 105 provided at the bottom of the pendulum flap 104 is driven over the inner cogwheel 106 and the outer cogwheel 107 based on the movement of the ship hull 103 that is determined by the size of the waveform. In an embodiment, the gearwheels 105 attached at each side of the pendulum flap 104 move towards the same direction over the inner cogwheel 106 and outer cogwheel 107 when the boat hull tilts. In an embodiment, as the gearwheels 105 moves over the inner cogwheel 106 and outer cogwheel 107, the pendulum flap 104 can swing 45 degrees forward or 45 degrees backward from its normal position. In an embodiment, the pendulum flap 104 must be of a substantial weight for maintaining an upright position during the movement of the boat hull. In an embodiment, as the gearwheels 105 moves over the inner cogwheel 106 and outer cogwheel 107, the generator 110 placed at the bottom of the pendulum flap 104 generates electricity and the generated electricity power depends on the size of the wave.

Referring to FIG. 5, illustrates the top view of the boat hull 100 installed with an apparatus for generating electricity. In an embodiment, the apparatus 100 comprises of a fork-shaped metal frame 102 mounted at the center on each side of the boat hull 100 by using the strong roller bearings 108. The generated electricity is transported from the generator 110 to the anchor-block through the anchor-cable that is encased within the fork-shaped metal frame 102. Referring to FIG.6, illustrates the design overview of apparatus. In an embodiment, the pendulum flap 104 is mounted from top of the ship hull 103 and is fitted with a generator 110 at the bottom over a horizontal driveshaft 109. As depicted in the figure, the horizontal driveshaft 109 mounts the gearwheels 105 on each side of the pendulum flap 104. Based on the movement of the gearwheels 105, the generator 110 generates electricity and transports the electricity through the fork-shaped metal frame 102 mounted at the center on each side of the boat hull 100.

Although the embodiments herein are described with various specific embodiments, it will be obvious for a person skilled in the art to practice the invention with modifications. However, all such modifications are deemed to be within the scope of the claims.
