(FILED OF THE INVENTION AND THE RELATED AR'T TI-IEREOF]
The present invention relates generally to a buoy having a means for self generating electricity using wave power, and more particularly, to a buoy having a means for self=
generating electricity using wave power, which converts the wave power of the undulating sea water into electric energy and uses this energy as a power for lighting, thus being permanently used at sea without additionally supplying electric power to the buoy.
?~ Generally, several types marking means, including unmanned lighthouses, lamp buoys and marker buoys, have been used to mark safe sea routes and dangerous zones for safely guiding ships at sea. It has to supply such a marking means with a power source for emittiilg light through a lamp, and such a marking means usually uses a dry battery as its power source.
However, in the conventional marking means, when the dry battery has been used for a ,s predetermined period of time, the energy of the dry battery is completely exhausted, so the battery nlLlSt be charged or replaced with a new one. Thus, the conventional marking means has a problem that, when it is required to charge or replace the battery with a new one, a person must get on board, go to a distort point around the marking means, draw the marking means having a considerable weight onto a ship, and disassemble the sealed casing housing the battery.
~ o Therefore, it is inconvenient for managers as well as dif~eult to charge the battery or replace the old battery with a new one.
In order to solve the above problems, there has been proposed a device for generating electric energy for such marking means using wave power. However, such a conventional device must have an additional anchoring means, such as the land or a lighthouse, adjacent to the ~ :i device so as to generate electric energy. That is, the conventional electric energy generating device has a problem in that it cannot be used in places where a means for anchoring or supporting the device does not exist, for example, in the middle of the ocean.
Furthermore, the conventional marking means has another problem that a lot of batteries have to be produced and are frequently installed in place of the old batteries, so the conventional ~O marking means causes unexpected increase of its management cost due to frequent replacement of the batteries, and leads to waste of natural resources as well as environmental pollution due to the wasted batteries.
(TECHNICAL SOLUTION FOR ACHIEVING THE INVENTIONI
Accordingly, the present invention has been made keeping in mind the above problems ', occurring in the prior art, and an object of the present invention is to provide a buoy having a means for self generating electricity using wave power, which generates electric energy using wave power in the middle of the ocean in which there are no support means for the buoy, thus being permanently used at sea without requiring additional power sources.
CONSTITUTION OF ~l'HE INVENTION]
_°s In order to accomplish the above object, the present invention provides a buoy having a means for self generating electricity using wave power, comprising: a float body having a constant size and buoyancy, which is floating on the sea; a lower actuating unit installed in the center portion of the float body in such a way as to be vertically set through the body and rectilinearly reciprocating through the body in a vertical direction due to a difference in a moving ~ o velocity between the float body and the actuating body when the body is moved by waves; an electric generator mounted on the float body and generating electric energy by converting a vertical reciprocating movement of the lower actuating unit into a rotating movement; an upper support mut installed on the float body for supporting the lower actuating unit; and a lamp indicating a position of the buoy using the electric energy generated by the electric generator.
According to this invention, the lower actuating unit includes a lower support casing set through the hole formed at the center portion of the float body, a shaft passing through the support casing iii such a way as to move up and down and provided on its upper portion with the rack, and a resisting plate mounted to the lower end of the shaft in such a way as to be perpendicular to the shaft, thus allowing the shaft to easily move up and down.
'?0 In the present invention, the resisting plate is subject to resistance when moving up and down in the sea, and has a circular shape of a predetermined diameter, or a predetermined polygonal shape.
Fiu-tliermore, according to this invention, the upper support tout includes an upper support casing installed on the float body, and an elastic member set in the support casing, and ~ a connected to the upper end of the shaft of the lower actuating unit for allowing the shaft to move up and down.
The present invention also provides a method of generating electric energy in the buoy, comprising the steps of: continuously moving the float body in a vertical direction by buoyancy in undulating sea water; vertically reciprocating the shaft of the lower actuating unit through the float body, while the resisting plate hardly moves in the waveless sea regardless of a vertical movement of the float body on the sea water; and converting the reciprocating movement of the shaft of the lower actuating unit into a rotating movement of the pinion engaging with the rack founed along the upper portion of the shaft:, and operating the electric generator using the rotatilig movement of the piiuon to generate electric energy.
Reference now should be made to the drawings, in which the same reference numerals a~-e used throughout the different drawings to designate the same or similar components.
Fig. 1 is a sectional view showing a buoy using wave power, according to the preferred embodiment of this invention.
As shown in the drawing, according to this invention, the buoy 30 using wave power is ~ s provided with several touts for converting the kinetic energy of undulating sea water into electric energy by means of an electric generator.
The buoy 30 includes a float body 6 having a constant size and buoyancy, which is floating on the sea, a lower actuating unit 10 installed in the center portion of the float body 6 in such a way as to be vertically set through the body 1 and rectilinearly reciprocating through the o body in a vertical direction due to a difference in a moving velocity between the float body 6 and the actuating body when the body is moved by waves, an electric generator 11 mounted on the float body 6 and generating electric energy by converting a vertical reciprocating movement of the lower actuating unit l0 into a rotating movement, and a lamp 15 mounted on the upper portion of the float body 6 and indicating a position of the buoy using the electric energy :as generated by the electric generator 11 and an upper support unit 14 which is supporting the lower actt~atiiig Lout 10 at the upper portion.
In the above constructions, at the center portion of the float body 6 is set a lower support casing 5 such that a shaft 7 constituting the lower actuating unit 10 passes through the support casing ~. A resisting plate 9 is mounted on the lower end of the shaft 7. The resisting plate 9 is :, subject to resistance when moving up and down in the sea, and has a circular shape of a predetermined diameter, or a predetermined polygonal shape. The rack 17 is formed along the upper portion of the shaft 7 reciprocating through the float body 6, and engages with the pinion 11 a connected to a rotating shaft of the electric generator 11, thus reversibly rotating the shaft of the electric generator 11.
The upper support unit 14 includes an upper support casing 3 installed on the float body 1 and an elastic member 13 set in the inner space of the support casing 3. The elastic member 13 is connected to the upper end of the shaft 7 of the lower actuating unit 10 for allowing the shaft 7 to elastically move up and down. In this case, a spring, which has a desired elastic modulus determined in accordance with the sire of the float body 1 and the weight of the lower ~ :p actmtiig mot 10, may be used as the elastic member 13.
On the upper portion of the upper support casing 3 is installed the lamp 15 and is connected to the electric generator 11, and receives electricity from the electric generator 11.
The lower support casing 5 positioned in the lower portion of said float body 6 receives the shaft 7 of the lower actmting tout 10 in its inner space, and is made of a corrosion resistant ~o material, such as stainless steel, so as to be prevented from being corroded by sea water.
In the meanwhile, comps>nents installed above the float body 6 are made of light materials, such as aluminwn, to reduce the weight, whereas components sinking in the sea are made of heavy materials, such as stainless steel. That is, the buoy 30 of this invention is designed such that the lower part of the float body 6 is heavier than its upper part, thus always ?, heepizg the buoy 30 perpendicular to the water surface.
Further, an illuminating means, may be provided with a brightness measuring means, such as an electric circuit having a C'.DS cell, for lighting a lamp only on dark occasions, and provided with a power control means for intermittently lighting the lamp, thus preventing the electric energy from being wasted, but effectively utilizing the energy.
:> The electric generator 11 generates electric energy using the rotating movement of the pinion 11 a, connected to the rotating shaft (not shown) of the electric generator 11, regardless of the rotating directions of the pinion 11 a. This generator 11 is operated by converting the reciprocating movement of the shaft 7 into the rotating movement of the pinion l la engaging with the rack 17 formed along the upper portion of the shaft 7.
The electric generator 11 is housed in a sealed container (not shown), which also houses a power supply part consisting of m accumulator for storing the energy generated by the electric generator 11 and a charger (not shown).
The operation of the buoy ming wave power constructed in this way will be described in detail with reference to the Figs. 2a and 2b.
Fig. 2a is a sectional view of the buoy of this invention, when a wave is high, and Fig. 2b is a sectional view of the buoy of this invention, when the wave is low.
Referring to the drawings, the rising height of the float body 1 floating on the sea is chmged depending on the height oL the wave. On the other hand, since the resisting plate 9 sinks in the sea where there is little movement of the wave, the moving activity of the resisting plate 9 ?o is relatively less than that of the float body 6.
Therefore, there is a difference in the moving velocity between the float body 6 and the resisting plate 9, so the lower actuating unit 10 rectilinearly reciprocates through the float body 6, thus rotating the pinion 11 a of the electric generator 11 by the rack 17. At this time, the rotating shaft of the electric generator 11 is also rotated.
When the wave becomes high, the float body 1 moves upwards, but the resisting plate 9 sinking in the sea is subj ect to resistance of the seawater and doesn't move as high as the body 6 moves, so the shaft 9 moves downward, thus straining the elastic member 13 set in the upper support casing 3.
When the wave becomes low, the float body 1 moves downwards, but the resisting plate ;~ 9 doem't move as low as the body 1 moves, so the shaft 7 moves upwards, thus returning the elastic member I 3 to its original position or compressing the elastic member 13.
Consequently, as far as waves continuously move at different heights, the electric generator contiizues running, thus being capable of self generating elasticity without requiring the supply of electric energy by a dry battery. In addition, the accumulator of the buoy accumulates ~ o surplus electric energy.
[EFFECT OF THE INVENTION) As described above, the present invention provides a buoy, which includes a float body moved by waves, a lower actuating unit extending through the center portion of the body and rectilinearly reciprocating through tlae body in a vertical direction due to a difference in the ~:p a111oL1I1t of movement between the Moat body and a resisting plate, and an electric generator operated by a rotating force generated by a conversion of a reciprocating movement of the lower actuating unit into a rotating movement of a pinion, thus easily generating the electric energy in the middle of the ocean where there is no support means, and substituting wave power for a dry battery as a source of the energy, therefore saving energy. Meanwhile, the conventional marking 2~ mems has a problem in that it is necessary to replace or charge a battery.
It is thus inconvenient to use the conventional marking means, in addition to taking time to replace or charge the battery. However, the buoy of this uivention can solve such problems experienced by conventional marking mews.
