Description

Technical Field

[0001] The present invention relates to a power generation rod and a power generation device using the power generation rod, and in particular to a power generation rod that produces electricity by utilizing the energy generated by the shaking of a ship or a floating body due to waves, and a power generation device using the power generation rod. Background Art

[0002] Recently, the use of environmentally friendly natural energy has been highly praised, and people are actively developing various power generation methods such as solar energy, wind energy, wave energy, tidal energy, and geothermal energy. However, only facilities that use solar energy and wind energy have been put into practical use, and other fields have not been widely put into practical use due to many problems in their economic or technical aspects.

[0003] In addition, due to recent environmental issues such as restrictions on greenhouse gas emissions, regulations are being actively formulated around the world to restrict fossil fuels and use electricity as a power source. Environmental groups concerned about air pollution are becoming more and more vocal, so for ships, the same eco-power system that uses clean energy as a power source is required, just like cars. So far, unlike land, the problem of exhaust gas has not been discussed too seriously in the ocean, but recently, with the increase in the size of ships and the number of voyages, serious air pollution has been caused, especially in coastal areas, so relevant countermeasures must be taken.

[0004] Ships using engines must be lightweight in order to save energy, and recently, a large number of research activities related to aluminum ships have been carried out to achieve lightweight.

[0005] In addition, various research activities are being actively carried out to improve the charging efficiency of batteries and utilize energy such as solar energy, wind energy, and wave energy.

[0006] Korean registered patent No. 10-1255728 discloses a wave power generator for a ship, which can generate electricity using wave energy during the navigation or operation of the ship, thereby realizing a hybrid electric ship that uses commercial electricity and internal combustion engines.

[0007] Existing wave power generation devices for ships generate electricity by rotating turbines when hit by waves. In addition, when fixed to a ship to receive wave energy, it is necessary to perform additional operations of placing and lifting the underwater turbine, and the ship's propulsion efficiency is reduced due to the large resistance.

[0008] Furthermore, since the turbine needs to be installed in a state where it can be driven by waves, its installation is also difficult. Summary of the invention

[0010] The object of the present invention is to provide a power generation rod that can generate electricity by utilizing the swaying of a ship and a power generation device utilizing the power generation rod.

[0011] The object of the present invention is to provide a power generation device that can generate electricity by means of shaking in three-axis directions.

[0017] In an embodiment of the present invention, it is characterized in that an embedding groove for connecting the first power generation rod to the third power generation rod is formed on the connecting member.

[0018] Effects of the Invention

[0019] In the present invention, the swaying of the ship is used to generate electricity, so compared with the existing method of directly rotating the turbine with the help of waves, the installation can be simplified and the efficiency can be improved.

[0020] Furthermore, in the present invention, electricity can be generated by means of swaying in the three-axis directions of x, y and z, so electricity can be generated even when the ship sways in only one direction.

[0021] In addition, there is no exposed or protruding part outside the ship or floating body, so no additional resistance will be generated during navigation, and there is no need to worry about damage due to collision with external objects. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention can be modified in many ways and has many embodiments. Specific embodiments will be illustrated in the accompanying drawings and described in detail in the detailed description. However, this is not to limit the present invention to a specific embodiment, but should be understood to include all modifications, equivalents and even substitutes included in the concept and technical scope of the present invention. In the process of describing the present invention, when it is determined that the specific description of the relevant known technology may make the gist of the present invention unclear, the detailed description related thereto will be omitted.

[0027] In the process of describing various components, terms such as first, second, A and B may be used, but the components are not limited by the terms. The terms are only used to distinguish one component from other components. For example, without departing from the scope of the claims of the present invention, the first component can be named as the second component, and similarly, the second component can also be named as the first component. The term and / or includes a combination of multiple related recorded items or one of the multiple related recorded items.

[0028] The terms used in this application are only used to illustrate specific embodiments and are not intended to limit the present invention. Unless the context clearly indicates otherwise, singular statements also include plural meanings. In this application, terms such as "including" or "having" are only used to indicate the existence of features, numbers, steps, actions, constituent elements, parts or the combination described in the specification, and should not be understood as excluding in advance the possibility that one or more other features, numbers, steps, actions, constituent elements, parts or the combination described may exist or be added.

[0029] Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0030] Figure 1 The power generating rod according to the present invention is illustrated, wherein Figure 1 The diagram (a) in the figure is an exploded view, and Figure 1 (b) shows a cross-sectional view of the stone combination.

[0031] The power generating rod according to the present invention is characterized in that it includes: a hollow rod 110, which is a tubular shape with a hollow interior; a coil 120, which is wound around the hollow rod; a support rod 130, which is inserted into the hollow rod and inserted along the length direction of the hollow rod; a magnetic body 140, which is embedded and combined with the support rod in a manner that it can move back and forth along the support rod; and a cover 150, which fixes the support rod and prevents the magnetic body from detaching by being combined with the end of the hollow rod.

[0032] The hollow rod 110 and the support rod 130 are non-conductors and can be made of plastic.

[0033] The support rod 130 and the hollow rod 110 are preferably of the same length.

[0034] After the support rod 130 is inserted into the hollow 112 formed on the hollow rod 110 and the magnetic body 140 is embedded in the support rod 130, the support rod 130 can be fixed by sealing the ends of both sides of the hollow rod 110 with the cover 150, and the magnetic body 140 can reciprocate along the support rod 130. The magnetic body 140 is donut-shaped and has a hole formed in the center, and the formed hole should be larger than the support rod 130.

[0035] Since the coil is wound around the outside of the hollow rod 110 , electricity can be generated when the magnetic body 140 reciprocates along the support rod 130 .

[0036] The magnitude and direction of the induced electromotive force are shown in the following mathematical formula 1.

[0037]

Mathematical formula 1

[0038]

[0039] de: amount of induced electromotive force generated

[0040] (-): The induced electromotive force is generated in the direction that hinders the change of the cross-linking magnetic flux of the coil

[0041] N: Number of turns of coil

[0042] dΦ: Change in cross-link magnetic flux

[0043] dt: time change

[0044] In addition, according to the change in the cross-linked magnetic flux due to the interaction between the coil (angled) related to the "six-degree-of-freedom motion of the ship" caused by wave energy and the magnet inside the coil affected by gravity, the induced electromotive force (e) is expressed as the following mathematical formula 2.

[0045]

Mathematical formula 2

[0046] e=-NωΦ,

[0047] N: Number of turns of coil

[0048] ω: angular velocity (=2πf), f=1 / T (period): frequency

[0049] Φ=BS: cross-linking magnetic flux, S: coil width, B: magnetic flux density, magnetic flux per unit area

[0050] The cover 150 fixes the support rod by being coupled to the ends of both sides of the hollow rod, and can also prevent the magnetic body 140 from being separated when the magnetic body 140 moves. In addition, in order to prevent the magnetic body 140 from being damaged when it collides with the cover 150, it is preferable to use an elastic material. For example, various elastic materials such as sponge or polyurethane can be used.

[0051] By connecting a plurality of the above-mentioned power generation modules, a power generation device capable of generating power in three-axis directions can be constructed.

[0052] Figure 2 Examples of power generation devices according to embodiments of the present invention are shown in the drawings.

[0053] Figure 2 The power generation device according to an embodiment of the present invention may include: a first power generation rod 100, arranged along a first direction; a connecting member 400, connected to the first power generation rod; a second power generation rod 200, connected to the connecting member, arranged along a second direction; and a third power generation rod 300, connected to the connecting member, arranged along a third direction.

[0054] The first direction, the second direction and the third direction are formed to intersect each other perpendicularly. That is, the first to third power generation rods can be vertically arranged along the x-axis, the y-axis and the z-axis.

[0055] The first to third power generating rods can be used as described above. Figure 1 A power generating rod for explanation.

[0056] An embedding groove 410 for connecting the first power generation rod to the third power generation rod may be formed on the connecting member 400 .

[0057] By connecting multiple power generation rods into a rectangular shape using connectors, electricity can be generated by the movement of the magnetic body no matter which direction the ship sways.

[0058] In this embodiment, only one cube is shown, but it can be expanded by connecting the power generation rods. That is, a plurality of power generation rods can be connected by a connector to form a module, and can be expanded according to the required amount of electricity.

[0059] The device can be applied to places where a lot of shaking occurs, such as ships, but is not limited to this, and can be installed in any place where the magnetic body can be moved by shaking.

[0060] Figure 3 An example of deployment to a ship is illustrated in FIG.

[0061] like Figure 3 As shown, in the present invention, it is not necessary to make the power generation device directly contact with the waves, so the installation is easy and there is no need to worry about the power generation device being damaged by waves or other floating objects.

[0062] Table 1 below shows the parameters of the above mathematical formula input for the simulation of the power generation device according to the present invention. Figure 4 The simulation results showing that the electric power generated by the power generation device according to the embodiment of the present invention is charged into the battery are shown.

[0063]

Table 1

[0064]

[0065] By inputting the values ​​in Table 1 into Mathematical Formula 2, an induced electromotive force of 8.5 V can be estimated, and when at least two modules are connected to charge a commercial starting battery, an induced electromotive force of 17 V or more can be obtained, thereby charging the secondary battery of a small ship while preventing it from being discharged.

[0066] The above content is described with the embodiment as the center, but this is only for illustrative purposes and not for limiting the present invention. Moreover, a person with general knowledge of the technical field to which the present invention belongs should understand that the present invention can be subjected to a variety of deformations and applications not illustrated within the scope of the essential characteristics of the embodiment. For example, each component specifically shown in the embodiment can be implemented by deformation. In addition, the differences related to the above deformations and applications should be interpreted as being included in the scope of the present invention as defined in the attached claims.
