[0010] The present invention can be modified in various ways, and the scope of the present invention should not be construed as being limited to the following detailed examples, which are provided to more completely explain the present invention to those skilled in the art.

[0011] Therefore, the shapes of components shown in the drawings may be exaggerated to emphasize a clearer description. It should be noted that the same components may be indicated by the same reference numerals in the drawings. Furthermore, detailed descriptions of the functions and configurations of known technologies that are deemed to unnecessarily obscure the gist of the present invention may be omitted.

[0012] First, the configuration of a power conversion device according to an embodiment of the present invention will be explained in detail with reference to FIGS. 1 to 6 as follows.

[0013] The power conversion device in this embodiment comprises a moving body 100 having a certain weight so that it can move in various directions due to the force of external fluids such as wind, vibration, tidal force, etc.; a hexahedral support housing 105 that supports the moving body 100; a connecting body 200 for connecting the support housing 105 and the moving body 100 to each other; hinge shafts 202 that are formed at multiple joints on the connecting body 200 and enable joint movement; and power conversion means that are attached to the hinge shafts 202 and convert the kinetic force of the moving body 100.

[0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0015] First, the construction of the moving body connecting power conversion device according to the first embodiment of the present invention will be explained in detail with reference to FIGS. 1 to 4 as follows.

[0016] It can be seen that the moving body 100 is a cylindrical moving body 101 having a cylindrical shape.

[0017] Meanwhile, the power conversion means in this embodiment is composed of a gear unit 300 that meshes with each other on both sides of the hinge shaft 202, and a power generation unit 500 that is connected to the gear unit 300 and generates electricity.

[0018] In addition, a rotary bearing 201 is provided at the connection portion between the connecting body 200 and the support housing 105 so that the moving body 100 can rotate.

[0019] It can also be seen that a bracket 203 and a rotating boom 205, which are vertically symmetrical, are connected to the connector 200.

[0020] The effects and advantages of the operation of the moving body connecting power conversion device of the present invention having the above-described configuration will now be considered in detail.

[0021] The power conversion device of the present invention can perform power generation conversion operation using kinetic energy power generated by the movement of the moving body 100 when installed on the sea or on land.

[0022] That is, when the moving body 100 is caused to move by an external force such as wind or tidal force, a rotational force is generated within a certain angle range at the locations of the multiple hinge shafts 202, and at this time, since the gear unit 300 is connected to the power generating unit 500 at the location where the rotational force is generated, electricity is generated and stored.

[0023] In particular, since a rotation axis (not shown) is also formed at the portion of the rotation bearing 201, it can be seen that power can be generated by power conversion even when the moving body 100 rotates horizontally.

[0024] Therefore, the power conversion device of the present invention maximizes energy efficiency by utilizing the rotational kinetic energy of the hinge connection part for various power conversions when a moving body of a certain weight is moved by external forces such as wind, tidal, or buoyancy.

[0025] In particular, the electric energy, thermal energy, etc. generated by the power conversion can be utilized immediately or stored in a separate storage facility for further utilization.

[0026] Meanwhile, FIG. 5 shows the configuration of a power conversion device according to a second embodiment of the present invention, in which the moving body 100 provided inside the support housing 105 is composed of a rectangular parallelepiped moving body 102 having a rectangular parallelepiped shape, and it can be seen that a rotating boom 204 is connected between the bracket 203 and the rotating boom 205 so that they can rotate freely in mutually perpendicular directions.

[0027] With this configuration, the rectangular parallelepiped moving body 102 moves in various directions due to external force, and power can be converted and generated at any time at each hinge axis 202 of the connecting body 200.

[0028] 6 to 10 show the configuration of a third embodiment of the present invention, which includes a number of moving bodies 100 having a certain weight so that they can move in various directions due to the force of an external fluid, a connecting body 200 for connecting each moving body 100 to each other at the top, hinge shafts 202 formed at a number of joints provided on the connecting body 200 to enable joint movement, and power conversion means provided on the hinge shafts 202 to convert the kinetic force of the moving body 100.

[0029] In this case, the moving body 100 in this embodiment becomes a floating moving body 104 that moves by waves or currents.

[0030] In addition, the connecting body 200 has a bilaterally symmetrical structure, and rotary bearings 201 are provided at the symmetrical connecting portions and the connecting portion of the moving body 100. At the upper ends of the rotating booms 204 on both sides, there are boom angle limiters 208 of a certain length for limiting the rotation angle of the rotating booms 204, connecting arms 206 for connecting the upper ends of the two paired rotating booms 204, and a square bar-shaped arm angle balancing device 209 for maintaining the bilateral balance of the connecting arms 206.

[0031] Meanwhile, as can be seen in FIG. 8, inside the rotating boom 204, there are configured a gear unit 300, which is a one-way rotation conversion planetary gear device, a speed-up planetary gear 400, and a power generating unit 500. The rotational force is transmitted to the gear unit 300 via an input shaft 310 to which the rotational force is transmitted from the hinge shaft 202, and the speed-up planetary gear 400 and the gear unit 300 are configured inside a planetary gear case 410.

[0032] 9 and 10, the gear unit 300 is configured by combining an inner case 320 in which a forward one-way clutch 321, a reverse one-way clutch 322, an input carrier 323, an input planetary gear 324, and an input ring gear 325 are assembled, and a gear case 330 in which a ring gear 331, a carrier 332, and a planetary gear 333 are provided. In the drawings, unexplained reference numerals 340 and 341 indicate an output shaft and a sun gear, respectively.

[0033] When the power conversion device of the present invention having such a configuration is installed on the sea, as the floating vehicle 104 floats on the water surface and flows due to waves and tidal currents, the rotational kinetic energy transmitted from the connecting body 200 connecting both sides of the floating vehicle 104 to the hinge axis 202 can be used to convert power into electricity and generate electricity in the power generation unit 500.

[0034] In particular, the rotational force transmitted to the input shaft 310 due to the movement of the rotating boom 204 is transmitted through the gear unit 300 and the speed-up planetary gear 400, thereby increasing the speed, thereby improving power generation efficiency.

[0035] 11 and 12 show the configuration according to the fourth embodiment of the present invention, in which the moving body 100 is composed of a shock-absorbing floating moving body 103 that can absorb external shocks, and the shock-absorbing floating moving body 103 is provided with flow restriction parts 106 connected to each other to restrict the flow range, and shock absorbing parts 107 are formed on the outside to cushion external shocks.

[0036] With this configuration, a large number of shock-absorbing floating vehicles 103 float on the water surface and are moved by the force of waves and currents, allowing for power conversion. At this time, the flow range is appropriately restricted by the flow restricting unit 106, and the shock-absorbing unit 107 can prevent damage to the shock-absorbing floating vehicles 103 from external impacts.

[0037] 13 and 14 show the configuration according to the fifth embodiment of the present invention, in which a number of floating vehicles 104 are connected by an interconnector 200 with a buoyancy section 109 at the top and a ballast section 110 at the bottom.

[0038] In addition, it can be seen that the connecting body 200 connecting both sides has connecting arms 206 on both sides connected by a truss boom 207, and a power generating unit 500 is configured on one side of the truss boom 207.

[0039] FIG. 15 shows the configuration of a buoyant body connecting body 200 according to the sixth embodiment of the present invention, in which the connecting portion of the floating vehicle 104 is configured by connecting a universal joint 210 and a spline 211 to a rotary bearing 201 in this order, and on the other side of the spline 211, the floating vehicle is connected by a universal joint and a rotary bearing in the reverse order.

[0040] Through this configuration, power conversion is performed by rotational motion in various directions, and the spline 211 allows control of the extension and contraction of length.

[0041] FIG. 16 shows a configuration according to a seventh embodiment of the present invention, in which a protective layer 101a is coated on the surface of a cylindrical moving body 101 to prevent surface contamination and to protect the surface.

[0042] In this case, the protective layer 101a preferably has a mixed composition of 10 to 30% by weight of polysulfone resin, 5 to 20% by weight of dimethylacetamide, 10 to 30% by weight of epoxy vitrimer resin, 10 to 20% by weight of potassium chromate, 1 to 10% by weight of cobalt naphthenate, 5 to 10% by weight of barium sulfate, 5 to 20% by weight of calcium carbonate, 1 to 10% by weight of polybenzimidazole, 1 to 10% by weight of isoflavonoid, 1 to 10% by weight of polycaprolactone, and 1 to 10% by weight of sodium fluoride.

[0043] With this configuration, when the cylindrical moving body 101 is moved by external forces such as wind or tidal force, the protective layer 101a can prevent damage and contamination caused by collision with surrounding structures.

[0044] In particular, the protective layer 101a contains a mixture of dimethylacetamide and epoxy vitrimer resin components to improve buffering, potassium chromate ensures uniform coating thickness throughout the coating process, cobalt naphthenate and barium sulfate improve the surface lubricity of the protective layer 101a to prevent adhesion of foreign matter and contamination, calcium carbonate improves durability by increasing coating density, polybenzimidazole and isoflavonoid prevent discoloration and deterioration of the coating layer, and polycaprolactone exhibits an advanced effect of improving coating stability through the catalytic function of polysulfone resin.

[0045] Although specific embodiments of the present invention have been described and illustrated above, it will be apparent to those skilled in the art that the power conversion device structure of the present invention can be modified and embodied in various ways.

[0046] For example, in the above embodiment, a configuration in which electrical energy is converted by power conversion has been described and illustrated, but the power conversion device of the present invention can be utilized in a form in which it is coupled to thermal energy or building facilities in addition to electrical energy.

[0047] Therefore, such modified embodiments should not be understood as being separate from the technical spirit and scope of the present invention, and such modified embodiments should be included within the scope of the appended claims of the present invention. [Industrial Applicability]

[0048] This has the advantage that the electrical energy, thermal energy, etc. generated by the power conversion can be used immediately or stored in a separate storage facility for further use.
