APPARATUS FOR CONVERTING POWER HAVING LOADING PRESSURE PLATE AND APPARATUS FOR GENERATING POWER

Technical Field The present invention relates to a power generating apparatus, and more particularly, to a power converting apparatus having loading pressure plates, which converts flowing of a fluid such as air or water of nature into rotary power to carry out power conversion and which is capable of generating such converted power to the outside, and a power generating apparatus comprising the same.

Background Art

Although most of energy indispensably required when humankind conducts civilizations has been dependent upon fossil fuel, there are problems of limited resources and environmental pollution. Therefore, researches have been carried out on the development of almost unlimited clean energies such as solar heat, terrestrial heat, wind force and tidal power, and some of them have been put to practical uses substantially.

Among such clean energies, wind energy is being the most universally put to practical use and has traditionally been developed through a variety of windmills.

In case of the wind energy, most of conventional rotary vanes are propeller type rotary vanes. The propeller type rotary vanes are freely used at places where strong wind magnitudes are secured while a plurality of plate type rotary vanes are used upright at places where weak wind magnitudes are secured so as to allow larger portions of the rotary vanes and wind to come in contact with each other.

However, the plurality of plate type rotary vanes that are used upright have a problem that expected rotary power can not be obtained as the wind interferes with the rotation of the rotary vanes when the rotary vanes rotate against wind in the opposite direction while rotary power is generated in a large amount when the rotary vanes are pushed by wind.

Researches have been conducted on methods for obtaining various useful energies including methods for waterpower generation, wave-power generation and tidal power generation as well as the foregoing wind power generation to obtain energies from flowing energies of nature such as water, waves, tidal water, and the like.

However, such conventional power generation methods have problems that the methods cause severe environmental damages, require high cost civil engineering and construction, and deteriorate economic efficiencies due to high yield losses in the processes of obtaining the energies.

The present invention is conceived to solve the foregoing problems. An object of the present invention is to provide a power converting apparatus having loading pressure plates, which converts flowing of a fluid such as air or water of nature into rotary power to carry out power conversion and which is capable of generating such converted power to the outside, and a power generating apparatus comprising the same.

On the other hand, the loading pressure plates comprise plate bodies, and head bodies formed on one ends of the plate bodies in such a shape that is pointed along a first direction, wherein lateral faces of the head bodies and those of the plate bodies are connected to each other in the streamlined shape.

Namely, the loading pressure plates are formed in the shape of a weeding hoe's vane as a whole, and have a streamlined cross-sectional shape.

Here, the loading pressure plates may further comprise a pair of tail bodies projected from both side portions of the other ends of the plate bodies in such a shape that is pointed along a second direction corresponding to the first direction. Here, the loading pressure plates may further comprise auxiliary tail bodies formed on the pair of the tail bodies and extended to a predetermined length along the longitudinal direction of the loading pressure plates. Further, the auxiliary tail bodies may be hinged to ends of the tail bodies.

Fig. 13 is a perspective view showing that ornaments are applied to a power converting apparatus of the present invention.

Referring to Fig. 1 and Fig. 2, a power converting apparatus of the present invention comprises a rotary body 100, a plurality of fixed rods 200 radially extending to a predetermined length around the rotary body 100 from an outer face of the rotary body 100, and a plurality of loading pressure plates 300 which are installed on end portions of the fixed rods 200 and which receive pressure from a flowing fluid to generate power for rotating the rotary body 100. The rotary body 100 may comprise a first fixed rotary shaft 110 with a predetermined length, and a first rotor 120 which is installed on the first fixed rotary shaft 110, and from which the fixed rods 200 extend to be formed.

Here, it is preferable to set up the first fixed rotary shaft 110 on the ground. Additionally, it is preferable that the fixed rods 200 and the first fixed rotary shaft 110 cross at right angles. Furthermore, the fixed rods 200 are preferably placed at the same level.

Although it is not illustrated with drawings, the fixed rods 20 may extend to face different levels. That is, the fixed rods 200 extend to a predetermined length respectively in different directions.

The constitution of the loading pressure plates 300 is as follows. Referring to Fig. 2, the loading pressure plates comprise plate bodies

320, head bodies 310 formed on one ends of the plate bodies 320 in such a shape that is pointed along a first direction, and a pair of tail bodies 330 projected from both side portions of the other ends of the plate bodies 320 in such a shape that is pointed along a second direction corresponding to the first direction.

Further, lateral faces of the head bodies 310, the plate bodies 320 and the tail bodies 330 are connected to one other in the streamlined shape. Here, the first direction is a direction that the loading pressure plates 300 are rotated according to flowing of the fluid while the second direction is a direction opposite to the rotating direction of the loading pressure plates 300.

Further, the loading pressure plates 300 can be bent to form convex faces.

Namely, the loading pressure plates 300 can be bent or folded such that inner faces of the loading pressure plates 300 connected to the fixed rods

200 receive a large amount of loading pressure of the flowing fluid, wherein the inner faces of the loading pressure plates 300 may be faces that substantially receive pressure from a fluid such as flowing air or water.

Of course, the loading pressure plates 300 may be formed in the flat shape.

End portions of the fixed rods 200 may be connected to central points C of the loading pressure plates 300, wherein the central points C of the loading pressure plates 300 are resistance central points that receive pressure from the fluid. Here, the inner faces of the loading pressure plates 300 are preferably perpendicular to the fixed rods 200. Although it is not illustrated with drawings, the inner faces of the loading pressure plates 300 may form oblique angles such that acute or obtuse angles are formed between the inner faces of the loading pressure plates 300 and the fixed rods 200. Referring to Fig. 1 and Fig. 2, the action of such constituted power converting apparatus is described.

A power converting apparatus may be installed in the water or on the ground that generates flowing of air. It is preferable to install the power converting apparatus in the water or on the ground in a way that the first fixed rotary shaft 110 is set up from the surface of water or the surface of the earth.

Accordingly, a plurality of the fixed rods 200 extending from an outer face of the first rotor 120 are disposed to form a predetermined angle, e.g., a right angle with the first fixed rotary shaft 110. Furthermore, the loading pressure plates 300 are installed on end portions of the fixed rods 200, wherein the end portions of the fixed rods 200 are connected to central points C on inner faces of the loading pressure plates 300.

Therefore, the fixed rods 200 can rotate around the first fixed rotary shaft 110 as a rotation center. In such a state, a fluid such as air or water generates a certain amount of flowing energy when water flows in the water, or the wind blows above the ground.

The flowing energy of the fluid has directivity and is capable of applying a certain amount of pressure to the loading pressure plates 300 are installed on the end portions of the fixed rods 200.

At this time, the loading pressure plates 300 may be pressurized to one direction by the pressure, wherein the pressurized direction is a direction in which the head bodies of the loading pressure plates 300 make a straight advance. Therefore, the loading pressure plates 300 pressurized to the one direction are capable of rotating the fixed rods 200 around the first fixed rotary shaft 110 as the rotation center at a predetermined speed.

Here, the head bodies 310 and the tail bodies 330 exposed to a large amount of resistance are pressurized at the same time by the flowing fluid such that the loading pressure plates 300 according to the present invention are rotated along moving directions of the head bodies 310.

Accordingly, the loading pressure plates 300 of the present invention are capable of converting flowing energy of the flowing fluid into rotary power of the fixed rods 200.

Furthermore, referring to Fig. 3 and Fig. 4, the end portions of the fixed rods 200 may be connected to positions D that are eccentric from the central points C of the loading pressure plates 300.

That is, the end portions of the fixed rods 200 are placed in a state that the end portions of the fixed rods 200 are eccentric to one sides from the resistance central points of the loading pressure plates 300. Preferably, the end portions of the fixed rods 200 are placed in the vicinity of the head bodies

310 of the loading pressure plates 300.

Therefore, as the resistance central points are moved and fixed toward the head bodies 310 having straight moving directivity from the central points C on the inner faces of the loading pressure plates 300, areas of the loading pressure plates 300 receiving pressure from the fluid are concentrated on the inner faces of the loading pressure plates 300 as well as the head bodies 310.

Therefore, force that moves in the direction of the pressure-receiving head bodies 310 increases.

Accordingly, if the resistance central points are eccentric from the central points C on the inner faces of the loading pressure plates 300, resistance of the loading pressure plates 300 is biased to further increase rotary speed of the fixed rods 200 as much as a predetermined rotary speed value. Therefore, a predetermined flowing energy may be converted into rotary power or power that increases in multiple proportion to the flowing energy.

Furthermore, referring to Fig. 5, the end portions of the fixed rods 200 and the loading pressure plates 300 may be hinged to each other by hinge members 500.

Namely, the loading pressure plates 300 are foldable within a predetermined folding angle range on the end portions of the fixed rods 200 by the flowing energy from the flowing fluid provided from the outside.

Here, the hinge members 500 comprise hinge brackets 510 installed on the loading pressure plates 300, and hinge shafts 520 installed on the hinge brackets 510 and inserted into rotary holes (which are not illustrated on the drawings) formed in the end portions of the fixed rods 200.

Further, the hinge members may further comprise catching brackets

530 formed on one sides of the hinge brackets 510 to block the loading pressure plates 300 and the fixed rods 200 such that the loading pressure plates 300 and the fixed rods 200 rotate to each other within an acute angle range.

Accordingly, the loading pressure plates 300 may be reciprocated and rotated within the acute angle range on the end portions of the fixed rods 200 along the direction of the flowing energy provided from the outside. Undoubtedly, a foldable angle range of the loading pressure plates 300 may be set in an angle range of less than 90 degrees or an angle range including 90 degrees.

Referring to Fig. 6, when such loading pressure plates 300 receive pressure or load from the flowing energy and rotate together with the fixed rods 200, since a power converting apparatus according to the present invention comprises hinge members 500 formed on connected portions between the loading pressure plates 300 and the end portions of the fixed rods 200 such that the loading pressure plates 300 are foldable on the end portions of the fixed rods 200, the loading pressure plates 300 are folded at rotary power-generating positions to minimize reaction force of the rotary power and further increase power to be converted into the rotary power accordingly.

In other words, such foldable loading pressure plates 300 are repeatedly folded and unfolded by a flow of the flowing energy to reduce non-loading sections and convert the flow into a predetermined power or more accordingly.

On the other hand, referring to Fig. 7, auxiliary tail bodies 331 may further be formed on the tail bodies 330 and of the above-mentioned loading pressure plates 300 in a way that the auxiliary tail bodies 331 extended to a predetermined length along the longitudinal direction of the loading pressure plates 300.

The auxiliary tail bodies 331 extend to a predetermined length along the longitudinal direction of the loading pressure plates 300 from projected positions on upper and lower parts of the tail bodies 330 of the loading pressure plates 300. That is, the auxiliary tail bodies 331 are formed on end portions of the tail bodies 330.

Here, when pressure is applied to the loading pressure plates 300 by the flowing fluid, the fixed rods 200 rotate the first fixed rotary shaft 110. At this time, the loading pressure plates 300 rotate while forming a rotation path around the first fixed rotary shaft 110 as the rotation center, and the auxiliary tail bodies 331 can easily remove backwash applied to rear parts of the loading pressure plates 300. Namely, the auxiliary tail bodies 331 are capable of stably guiding the rotation of the fixed rods 200 and the loading pressure plates 300 and increasing the load difference.

In the meantime, referring to Fig. 9, a plurality of auxiliary loading pressure plates 400 may further be installed on the fixed rods 200 according to the present invention in the same shape as the above-mentioned loading pressure plates 300.

Here, the auxiliary loading pressure plates 400 preferably have the same size ratio as the loading pressure plates 300.

Accordingly, the loading pressure plates 300 and the auxiliary loading pressure plates 400 having the same size ratio are installed on one of the fixed rods 200 to increase the applied area of the pressure received from the flowing fluid.

In other words, the fixed rods 200 and the loading pressure plates 300 can increase the rotary power applied around the first fixed rotary shaft 110 to a predetermined value or more as the foregoing pressure applied area increase to a predetermined value or more.

Additionally, the auxiliary loading pressure plates 400 may have size ratios different from those of the loading pressure plates 300.

Here, it is preferable to form the auxiliary loading pressure plates 400 in ratio sizes gradually reduced from the ratio sizes of the loading pressure plates 300 along the rotary rotor 120 from the end portions of the fixed rods 200.

As described above, it is preferable that connecting position levels of the auxiliary loading pressure plates 400 and the fixed rods 200 are the same as those of the foregoing loading pressure plates 300 and the end portions of the fixed rods 200 when additionally installing the auxiliary loading pressure plates 400 on the fixed rods 200.

Further, rotary holes 410 are formed in the auxiliary loading pressure plates 400, hinge shafts 420 are formed on inner sides of the rotary holes 410, and the hinge shafts 420 are inserted into holes 201 formed in the fixed rods

200. Therefore, the auxiliary loading pressure plates 400 are rotatably installed on the fixed rods 200.

Therefore, the fixed rods 200 may be connected to the central points C of the auxiliary loading pressure plates 400 as illustrated in Fig. 1 and Fig. 2, or connected to positions that are eccentric to one sides from the central points C of the auxiliary loading pressure plates 400 as illustrated in Fig. 3 and Fig. 4.

On the other hand, referring to Fig. 13, a gear part 600 may be additionally installed on an end portion of the rotary body 100 to perpendicularly convert the direction of the rotation center of the rotary body 100, and a plurality of rotary rods 700 may be additionally installed on the end portion of the rotary body 100, the rotary rods 700 radially extending to a predetermined length from the gear part 600 and having ornaments 710 installed on ends thereof.

The gear part 600 comprises a first bevel gear 610 installed on the top of the fixed rods 200 of the rotary body 100, and a second bevel gear 620 engaged with the first bevel gear 610 to convert the rotary direction.

Here, a fixture 630 is installed on the second bevel gear 620. The rotary rods 700 radially extend to a predetermined length from an outer face of the fixture 630. In such a case, the rotary body 100 is immersed into the water, and the rotary rods 700 rotating around other rotation center according to the rotation of the fixed rods 200 may be sequentially immersed into the water.

Therefore, a power converting apparatus according to the present invention is capable of simultaneously converting flowing energy from a water flow into rotary power in the water and obtaining a tourism effect by using the ornaments 710 such as dolphin-shaped ornaments immersed from the outside of the water into the water sequentially and repeatedly.

In the meantime, as illustrated in Fig. 8, the fixed rods 200 may extend in a state that the fixed rods 200 are disposed at predetermined intervals along a spiral path formed along the longitudinal direction of the rotary body 101.

Here, the rotary body 101 comprises a second fixed rotary shaft 111 on which the fixed rods 200 are installed in a state that the fixed rods 200 are extended from the second fixed rotary shaft 111 , and a second rotor 121 installed on the second fixed rotary shaft 111. Further, it is preferable to additionally install an active yaw control device 131 which is disposed at right angles with the second fixed rotary shaft 111 and connected to the second rotor 121 to adjust the direction of the rotary body 100 such that the rotary body 100 faces the flowing direction of the fluid.

Meanwhile, although it is not illustrated on the drawings, a power converting apparatus of the present invention comprises stoppers that allow an operator to stop the rotation of the power converting apparatus comprising the fixed rods 200, the rotary body 100 and the loading pressure plates 300 during maintenance or emergency. The stoppers may be rings or clips for binding the loading pressure plates 300 and the fixed rods 200 to prevent the rotation of the loading pressure plates 300 and the fixed rods 200, and the stoppers may be installed on one faces of the hinge brackets 519 or the loading pressure plates 300.

Furthermore, an ordinary brake device may be installed at a predetermined position of the first fixed rotary shaft 110 to allow the operator to stop the rotation of the rotary body 100 during maintenance or emergency.

Meanwhile, the foregoing head bodies 310 and tail bodies 330 of the loading pressure plates 300 may be diversely modified into shapes described below before the head bodies 310 and tail bodies 330 are adopted. Referring to Fig. 10, the loading pressure plate 300 may be a loading pressure plate 300' comprising a head body 310' from which one pair of pointed portions may be projected along a moving direction of the loading pressure plate 300', and a tail body 330' on which a round groove is formed along the moving direction of the loading pressure plate 300'. Furthermore, referring to Fig. 11 , a loading pressure plate 300" may comprise a tail body 330" having portions formed on both ends thereof such that the portions are pointedly projected oppositely to a moving direction of the loading pressure plate 300", and the loading pressure plate 300" may further comprise a bent tail body 332" formed by dividing a portion of the tail body 330" from the portions between the portions and bending the portion to the inner side of the loading pressure plate 300" at a predetermined angle. Here, 320' and 320" are plate bodies.

Furthermore, referring to Fig. 12, the loading pressure plate 300 may be a loading pressure plate 300'" formed in the shape of a shark's fin as a whole. The loading pressure plate 300'" may comprise a first body 310'" formed in an airfoil shape of which one side is pointed, and a second body 320'" set up along the center of the first body 310'" and formed in a fin shape. Outer lines of the first and second bodies 310'" and 320'" of the loading pressure plate 300'" are formed in a streamlined shape as a whole.

The power generating apparatus may comprise the above-mentioned power converting apparatus, and an electric generator (which is not illustrated on the drawings) for obtaining converted power from the power converting apparatus.

Therefore, the power generating apparatus is capable of easily generating the converted power to the outside after converting the flowing energy of the fluid into power of the rotary power using such constituted power converting apparatus.

Although the technical spirit of the present invention has been described with reference to the accompanying drawings, the description does not limit the present invention but merely explains the preferred embodiments of the present invention. Further, it will be understood by those skilled in the art that various changes and modifications can be made thereto without departing from the technical spirit and scope of the present invention.
