Description

DESCRIPTION
WAVE DAMPING SYSTEM FOR MARINE VEHICLES Field of Invention
This invention relates to a wave damping system, formed to prevent yacht-, boat-, or vessel-like floating objects from becoming affected by waves, and applicable to the entirety or to a determined section of a floating object, either during production, or afterwards.
Prior Art
Catamarans, trimarans, and similar systems have employed with the purpose of minimizing the effect of waves on boats. While a catamaran is a marine vehicle formed of two interconnected floats for use in cruises, a trimaran can be described as a catamaran with three floats. Even if the wave effects are reduced by means of these systems, they could not be come down to the below of discomforting levels
Additionally, a boat keeps rolling even while it is not cruising (i.e. it is moored or anchored) in terms of the systems according to the prior art, this fact shortening the lifespan of and wearing off the boat, reducing the comfort, and possibly causing health problems. Aiming to minimize this rolling influence during construction brings about challenges or difficulties in the design and living space of the boat and in the engineering works. Thanks to the our present invention, it shall be feasible both to eliminate the rolling problem of existing boats, and to pave the way for the design, manufacture, and engineering works of a boat to be newly constructed. When this system is applied to a section/a deck of a standard boat, that part of the boat will perform a movement against a wave by means of a servo system so as to dampen the wave and to reduce the rolling influence to an imperceptible level. Additionally, another method used in this current technique for providing boat stabilization is based on a gyroscope. A gyroscope is an instrument, operating based on maintaining the angular momentum, and used in measuring or setting the direction for maintaining the angular balance. Even if this method dampens the effect of a wave by 55%, the boat is still under the influence of the same by 45%. The system developed according to the present invention reduces the wave influence to an almost-zero level.
A further method is based on stabilizer wings. The stabilizer wings open, like the wings of a plane do, on both sides of a boat towards the exterior, and thus reduces the influence of waves, but the wave still keeps its influence.
Additionally, no method according to the prior art is capable of reducing the pitching influence of a wave.
In conclusion, the inadequacy of the current solutions and the presence of a need towards a wave damping system, formed to prevent yacht-, boat-, or vessel-like floating objects from becoming affected by waves, and applicable to the entirety or to a determined section of a floating object, either during production, or afterwards, necessitated a development to be made in the relevant technical field.
Object of Invention
One object of this invention for eliminating the drawbacks of the prior art is its feature that makes it applicable to existing boats afterwards.
Another object of this invention is to enlarge the existing limitations on the boat design, by reducing or eliminating the incremental cost increases and any losses to occur in the living spaces on behalf of minimizing the influence of waves on a boat. A further object of this invention is to prevent the sinking risk in the case of a incidental marine accident, by providing a double-bottom boat form as long as this invention is to be applied to the entirety of a boat during construction of boat.
Another object of this invention is to be stabilized either the entirety or just the living space of a boat by means of the rolling and pitching effects-damping system according to this invention, as a result of applying this system to the whole boat, to a section thereof, or to one or several deck(s) thereof. It is aimed at the system according to this invention to eliminate both the rolling and pitching effects, and if desired, to make this system applicable together with other stabilizing methods. In order to provide the aforesaid advantages, this invention provides a wave damping system, comprising a hull, at least one movable deck connected to the hull by means of at least two drive elements, and at least one balance sensor placed in the hull and/or deck for detecting any imbalances, and serving to keep the movable deck in parallel to the earth by damping the wave movements as a result of producing a movement on a direction which is opposite to the movement direction of the hull under the influence of wave movement by means of drive elements.
In a preferred embodiment of the present invention, the drive elements provided in the form of pistons for damping a wave are hydraulic or pneumatic pistons. These drive elements may also be in the form of a threaded rod or a rack-based drive system. Said drive elements serve to dampen a wave movement on three axes.
In a preferred embodiment of this invention, a spherical bearing is provided, placed on the middle (on the projection of the geometric center) of the area where the subject system is applied, and supporting the respective deck while said drive elements are in movement for damping the waves.
Structural and characteristic features, and all advantages of the present invention shall be made clear by means of annexed figures described here below and a detailed description written with references to said figures; therefore the present invention must be evaluated by taking into consideration these figures and the detailed description as well.

A: wave damping system Detailed Description of Invention
This invention provides a wave damping system (A), formed to prevent yacht-, boat-, or vessel-like floating objects from becoming affected by waves, and applicable to the entirety or to a determined section of a floating object, either during production, or afterwards.
The system (A) according to the present invention is applied to marine vehicles and comprises a hull (5). The hull is the section that floats on the water. A movable deck (2) is provided, which is connected to said hull (5) by means of at least two drive elements (3).
At least one balance sensor (1 ) for detecting any imbalances is placed in said hull (5) and/or said deck (2). The system (A) according to the present invention produces a movement on a direction which is opposite to the movement direction of the hull (5) under the influence of waves by means of said drive elements (3). Thus, the wave movements are damped so that the deck (2) is kept parallel to the earth.
The system (A) according to the present invention serves to prevent a boat (5) from becoming influenced by waves while the boat is cruising on water, or is anchored, or moored either to a piece of land or to a float. When the system (A) is applied to one or to several deck(s) (2) of a boat (5), the drive elements (3) used for keeping the area of application uninfluenced from the rolling and pitching effects of waves are controlled by the servo system (4) according to the balance sensors (1 ) detecting any imbalances.
The drive elements (3) illustrated in figures 1 , 2, 3, and 4 may be in the form of hydraulic and pneumatic pistons, a motor-driven threaded rod or a rack-based drive system (A). Thus, the area where the system (A) is applied shall be moved on a direction that is opposite to the direction of a wave and so will be kept parallel to the earth. As illustrated in figures 2 and 3, for instance, while the piston, i.e. drive element (3) on the side facing an incoming wave will be contracted or shortened to keep the area where the system (A) is applied parallel to the earth, the opposite drive element (3) will be extended for maintaining the balance. Thus, the area where the system (A) is applied will be kept stable.
As can be seen in figures 1 and 4, a spherical bearing (4) provided on the middle of the area where the system (A) is applied is employed for supporting the respective plane while the drive elements (3) are operating. Depending on the size of the area of application, said spherical bearing (4) may be omitted. Since it will be more difficult to keep the system (A) stable as the size is increased, it will become possible to control the area of application by lower forces by means of the spherical bearing (4) provided exactly in the central position. In other words, the spherical bearing (4) facilitates the operation of the system (A) when the size becomes higher. As illustrated in Figure 4, the system (A) according to the present invention can be implemented by drive elements (3) composed of 3 pistons, or of 4 or more pistons (Figure 4).
If the mass of the balanced section (2) is close to the mass of the imbalanced section (the portion remaining in the water) (1 ), the section/deck (2) balanced against the influence of a wave may tend to push or immerse the floating section (1 ) more into the water or to increase the rolling and pitching thereof under the influence of reactive forces. These forces emerge when the drive elements (3) are extended, i.e. when the boat falls from a wave. In order to prevent this, a gyroscope can be placed in the balanced section/deck (2) and the reactive forces can be reduced accordingly.
