Description

Wave power generator without horizontal movement component of magnet

The present invention relates to a wave power generator, and relates to a wave power generator for converting wave energy of blue waves into electrical energy.

Recently, due to the depletion of fossil fuels, efforts and attention are being made to secure new and renewable energy that can generate power in an infinite amount of energy sources and in an environmentally friendly way. As part of this, wave power generation systems that generate electricity using wave energy have attracted attention.

There are two ways to generate electricity by using wave energy of wave generated from ocean wave. The first method is a method of making a wave power generator between a permanent magnet and a coil between two floating bodies relative to each other, the second method is to insert a mass in one floating body relative to each other And a permanent magnet and a coil between the floating body to create a wave power generator.

The first method requires two floats to move relative to each other, one float to be anchored to the ocean floor, the other float to float on the wavefront, and allow relative movement in a watertight state between the two floats. shall.

The second method requires only one floating body fixed to the sea floor and provides a watertight structure only to the one floating body. Thus, the first method has the advantages of being structurally simple and easy to maintain than the first method. Rather, it is a recent wave power generation method. The second method is to support the weight of the heavy body by the elastic body in the floating body to increase the shank equivalent (amplitude) of the heavy material, and the intrinsic attenuation of the elastic body to the frequency of the wave having the heavy material By adjusting the frequency, a resonance shape between the elastic body and the wave is generated to maximize the amount of shank movement of the heavy object, and the power generation efficiency is increased. An example thereof is disclosed in WO2005 / 040603.

However, in the resonant wave power generator, the magnet is connected to the float frame with a spring or the coil is connected to the float frame with a spring to produce the maximum power by resonating with the frequency of the blue wave when the magnet and the coil alternately move. The structure is connected. However, in order to produce the maximum power under the same conditions, the direction of change of the magnetic field and the direction of the coil must be perpendicular to each other (Federday and Lenz's law), but the maximum power can be produced. Due to the structural features of the springs employed for the resonance between the generators, even when the magnet's maximum displacement occurs during resonance, horizontal components are present in the spring's kinetic components, which causes the magnetic field's direction of change and the coil's direction to be perpendicular to each other. Even if this happened, there was a problem that the maximum power production is not possible.

The present invention has been proposed to solve the above problems, by forming a guide protrusion and a guide groove in the magnet and the coil, by inserting the spring into the guide means to move, the horizontal movement component during the mutual movement of the magnet and the coil The object of the present invention is to provide a wave power generator capable of producing electric energy with maximum efficiency when resonating by allowing the direction of change of the magnetic field and the winding direction of the coil to be exactly perpendicular to each other.

The wave power generation apparatus in which the horizontal motion component of the magnet is removed to achieve the object of the present invention is an outer case 10 floating on the surface; installed inside the outer case and the upper and lower frames (21, 22) and the side frame (23) A frame 20 consisting of; Cylindrical spring guides 30 which are respectively installed on the upper and lower frames and have a hollow; A spring 40 installed inside the spring guide hollow; a cylindrical coil part 50 fixed to the side frame 23 and having a coil wound therein and having a hollow; formed on a hollow outer surface of the coil part A plurality of linear guide grooves 51; A cylindrical magnet 60 moving upward and downward through the hollow of the coil part; a plurality of linear guide protrusions 61 formed on an outer surface of the magnet; formed at both ends of the magnet and coupled to the spring It characterized in that it comprises an elastic connecting means (70).

The wave power generation apparatus in which the horizontal motion component of the magnet is removed for achieving the object of the present invention is characterized in that the lower portion of the case 10 is formed with a space 11 filled with a heavy material so as to have a center of gravity at the bottom of the case 10.

In the wave power generation apparatus in which the horizontal motion component of the magnet is removed to achieve the object of the present invention, the plurality of guide grooves 51 and the plurality of guide protrusions 61 are coupled by mutually fitting type while maintaining a gap at a predetermined interval. It is characterized by.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, words used in this specification and claims should not be construed as being limited to the common or dictionary meanings, and the inventors may appropriately define the concept of terms in order to best describe their invention. Based on the principle of the present invention, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

The wave power generation device of the present invention is a power generation device that produces electricity by converting the up and down motion of a wave into the relative motion of a magnet and a coil in the wave power generation device. Normally, a power generating device that generates power is a device that generates electricity by inducing a mutual kinetic relationship between a magnetic field and a conductor. Mutual kinematics refers to the relationship between a conductor's movement in a stationary magnetic field or a change in the surrounding magnetic field with respect to a stationary conductor. The current is generated by the electromotive force induced by the law of law (both laws are the basic principles of the generator, so the detailed explanation is omitted).

The wave power generator of the present invention uses the position change energy of the wave as a power source that causes the mutual motion relationship between the magnetic field and the conductor. In other words, when a floating body with a power generator is built on the surface of the blue water, the floating body also moves up and down by the up and down movement of the blue wave. The vertical motion of the floating body causes the mutual movement of the magnet and the coil of the power generator installed inside the floating body, thereby producing electricity according to the law of the above-described Faraday and Lenz.

A conventional wave power generator will be described with reference to FIG. 1. In the past, springs S1, S2, and S3 were used for resonance between a wave and a wave power generator. Resonance is to transmit the up and down kinetic energy of the blue wave to the coil and the magnet so that the coil (11, 13) and the magnet (15, 17) in the wave power generator to the maximum relative movement. As shown in Fig. 1, a spring means is conventionally used as a configuration for causing such resonance. That is, when the coil (conductor) is fixed to the frame of the wave power generator, which is a floating body, and the magnet is fixed to the frame (5,7) by using a spring, blue up and down kinetic energy is transmitted to the magnet through the spring and the spring Through repeated compression / tension motion of the magnet, the vertical motion of the magnet reaches its maximum value. The maximum movement force of the magnet is the maximum vertical movement distance, which causes the maximum magnetic field change to allow the maximum power production. As such, resonance is required for maximum power generation, and a means called spring is conventionally used for resonance. However, even if resonance occurs due to a structural feature of a spring used to induce resonance in the related art, the vertical movement component (up and down movement component) is mainly included among the movement components of the magnet, but some horizontal movement components exist. Because resonance refers to a state where the vertical motion of the spring and the vertical motion of the wave are synchronized, the vertical motion of the spring is affected by the vertical motion of the blue. In reality, blue is mainly used for vertical movement (vertical), but it is also known that horizontal movement is also performed, that is, the analysis of blue's motion component mainly has vertical component but also horizontal component. If so, the spring's motion, which is the configuration adopted for resonance, is also synchronized with the blue's motion, which mainly moves up and down, but also causes some horizontal motion (components swinging in the horizontal direction). This affects the movement of the magnet connected to the spring, so that the magnet mainly moves up and down (vertical), but also includes a horizontal motion component (a component that swings in the horizontal direction).

The maximum power is generated when the direction of change of the coil and the magnetic field is perpendicular to the condition of the same amplitude change (magnitude up and down movement of the magnet) in power generation. If the direction of change of the coil and magnetic field is not perpendicular, it produces less power than when it is vertical. The conventional wave power generator shown in FIG. 1 adopts a constituent means called a spring to cause resonance between the wave and the wave power generator, but as mentioned above, the spring has only 100% vertical movement due to the structural features of the spring. Rather, it has some horizontal component of motion (there is a component that swings in the horizontal direction). As a result, the magnets connected to the spring also do not have 100% vertical motion with respect to the coil and contain some horizontal motion components (components that swing in the horizontal direction). As a result, even if resonance occurs, maximum power production is impossible.

The present invention provides a guide groove and a guide protrusion, respectively, to the magnet forming the magnetic field and the coil portion serving as a conductor to solve the problems of the conventional wave power generator mentioned above, and at the same time, the up and down kinetic energy of blue By adopting the cylindrical guide, which is a means of restraining the horizontal motion component of the spring, which transfers to the motion, the horizontal motion component is structurally removed during mutual movement of the magnet and the coil so that the magnet movement has only the vertical motion component with respect to the coil. It is an object of the present invention to induce the production of power.

Hereinafter, the present invention will be described in detail with reference to FIGS. 2 to 4.

As shown in FIG. 2, the wave power generator according to the present invention includes an outer case 10 floating on the water surface, a frame formed inside the outer case and including upper and

lower frames

21 and 22 and side frames 23. 20), the cylindrical guide 30 is installed in the upper and lower frames, respectively, having a hollow, the spring 40 is installed in the hollow of the cylindrical guide, fixedly installed on the side frame 23, the coil is wound inside A cylindrical coil portion 50 having a hollow, a plurality of linear guide grooves 51 formed on the hollow outer surface of the coil portion, a cylindrical magnet 60 that moves up and down while passing through the hollow of the coil portion And a plurality of linear guide protrusions 61 formed on the outside of the magnet, and elastic connecting means 70 formed at both ends of the magnet and vertically coupled with a spring in the hollow of the cylindrical guide.

In the wave power generator having such a structure, the case 10 has a cylindrical shape with a space formed therein. Therefore, the components necessary for power generation are installed inside the case, and the case floats due to buoyancy at the surface of the water, and moves up and down along the blue. Will be filled.

The frame 20 is installed in the inner space of the case 10. The frame 20 is composed of upper and

lower frames

21 and 22 and side frames 23. The cylindrical guides 30 having hollows are formed on the upper and

lower frames

21 and 22, respectively. A spring 40 is inserted and installed in the hollow inside the guide. The cylindrical guide minimizes horizontal movement of the spring during vertical movement. Specifically, the spring and the elastic connecting means 70 to be described later is coupled in the hollow of the cylindrical guide. The resilient connecting means has a cylindrical portion in a shape in which a plate-shaped plate material 71 and a cylinder 72 are connected to the magnet, and the plate-shaped plate material is in contact with the spring. Due to the above constitutional features, the vertical movement force due to the tension / compression of the spring is transmitted to the magnet through the elastic connecting means. The up and down kinetic energy of the blue is transmitted to the magnet through the spring, the elastic connecting means 70 is used as a transmission medium for transmitting the kinetic force of the spring to the magnet. However, there is a horizontal component in addition to the vertical component of the blue motion component, and this horizontal component is transmitted to the spring, so that the spring also has a horizontal component in addition to the vertical movement. However, the kinetic force of the spring is transmitted to the magnet through the elastic connecting means 70 in the hollow of the cylindrical guide, the elastic connecting means is a structure reciprocating in the cylindrical guide hollow so that even if there is a horizontal motion component in the spring of the cylindrical guide The kinetic force transmitted to the magnet through the elastic connecting means reciprocating in the hollow is transmitted only the vertical motion component from which the horizontal motion component is removed. That is, in the case of the conventional wave power generator without the cylindrical guide spring has a horizontal component of movement (component horizontally swinging) of the predetermined portion during the vertical movement, the present invention is vertical vertical reciprocating movement in the hollow of the cylindrical guide Since the kinetic force of the spring is transmitted to the magnet through the elastic connecting means, the horizontal motion component is structurally limited and minimized.

One end of the spring 40 inserted into the cylindrical guide 30 is fixedly connected to the upper /

lower frames

21 and 22, and the other end is fixed to the magnet 60 by an elastic connecting means 62 formed at one end of the magnet. And fixed connection. By the above structure, the blue up and down kinetic energy is transmitted to the magnet through the spring, and the magnet moves up and down through the hollow of the coil part 50 in which the coil is wound inside. The relative vertical motion of the magnet relative to the coil part causes a change in the magnetic field in the coil part, and the electromotive force is formed in the coil part by the law of Faraday and Lenz, which are the principles of the generator.

3, the magnet and the coil unit of the present invention will be described in detail. Figure 3a is a side cross-sectional view of the wave power generator of the present invention, as shown in Figure 3a, the magnet generator 60 and the coil unit 50 in the configuration directly involved in power production in the wave power generator of the present invention. The coil part 50 has a coil wound therein and a cylindrical shape having a hollow shape and is fixed to the side frame 23. The coil installed inside the coil part is wound inside the coil part along the cylinder circumference in a horizontal direction perpendicular to the direction of motion of the magnet. The magnet 60 has a cylindrical shape and penetrates the hollow formed in the coil part and moves up and down. In the related art, the magnet is composed of a plurality of magnets and a plurality of magnets are interconnected by a spring, but the present invention is composed of a cylindrical integral magnet. The integrated magnet may be configured such that a plurality of N poles and S poles are alternately arranged, or an intermediate zone is disposed between one N pole and S pole.

The vertical motion of the cylindrical magnet consists of the transmission of blue vertical motion energy through the spring. FIG. 3B is a cross-sectional view of the magnet and the coil part of the present invention. As shown in FIG. 3B, a plurality of linear guide grooves 51 are formed on the inner hollow surface of the coil part 50, and the upper and lower parts of the coil part are formed. A plurality of linear guide protrusions 61 are formed on the moving magnet. The guide protrusion and the guide groove serve as a constituent means for removing a horizontal motion component among the motion components of the magnet which are moved up and down relative to the coil part, and after the guide protrusion is coupled to the guide groove by fitting, the magnet is coiled. The relative vertical movement is performed while maintaining a constant gap (void) with respect to. As mentioned above, the maximum electric energy production becomes possible when the direction of change of the magnetic field (up and down direction, which is the movement direction of the magnet in the present invention) is perpendicular to the direction of the coil part (the direction perpendicular to the direction of movement of the magnet in the present invention). If there is a component that is not perpendicular to the change direction of the magnetic field and the direction of the coil part, the generated electric energy decreases accordingly. For this reason, the present invention uses the configuration of the guide protrusion and the guide groove to minimize the horizontal movement component of the magnet's motion component.

The linear guide protrusion 61 and the guide groove 51 formed in the magnet 60 and the coil part 50 of the present invention suppress the horizontal motion component of the magnet when the magnet moves up and down relative to the coil part and move up and down. Serve up and down movement guide to do only. That is, the blue up and down motion is transmitted to the magnet through the spring and the magnet moves up and down with respect to the coil part. At this time, the magnet is guided only by the up-and-down movement by the linear guide protrusion and the guide groove of the present invention even though the structural feature of the spring has a horizontal motion component that swings in the horizontal direction. This is because the magnet is moved up and down through the hollow of the coil part while the coil part is fixed to the side frame. The magnet and the coil part are moved in a horizontal direction with respect to the coil part by the coupling structure of the guide protrusion and the guide groove. This is because the relative motion having only the vertical motion component without the horizontal motion component is allowed. In the absence of the guide protrusion and the guide groove, the magnet penetrates the hollow of the coil portion and moves up and down, but the movement component also includes a horizontal movement component that swings in the horizontal direction. This is because the spring that transmits the up and down force to the magnet has a horizontal component, i.e. when the magnet moves relative to the coil part with the guide protrusion coupled to the guide groove, the magnet is always horizontal to the coil part. Only the vertical component (upper and lower components) without the component will move.

As described above, the spring 40 transmits the vertical motion force of which the horizontal motion component is suppressed by the cylindrical guide 30 to the magnet, and the magnet which moves vertically through the hollow of the coil part has a guide protrusion 61 and a guide. By moving only in the state of the vertical component whose horizontal movement component is suppressed by the structural feature of the groove 51, the horizontal component is minimized so that the change direction of the magnetic field and the direction of the conductor (the winding direction of the coil) have only the vertical component. Therefore, the maximum magnetic field is induced in the coil to generate the maximum electromotive force in the coil. That is, the wave power generator of the present invention has a cylindrical guide 30, an elastic connecting means 70, a guide groove 51, a guide protrusion ( 61), the horizontal motion component of the magnet is optimized by the compositional feature, which can cause maximum electromotive force in resonance. The induced electromotive force supplies electricity to the outside through a power terminal (not shown) formed at one side of the coil unit.

Figure 4 is a view showing the positional relationship between the position of the magnet and the coil of the present invention and the wave position, Figure 4a shows the state that the wave power generator of the present invention is most down the surface of the blue wave, the magnet It is in the highest upward position relative to the coil portion. Figure 4b shows a state in which the wave power generator of the present invention is most raised above the surface of the blue wave, wherein the magnet is in the lowest downward position with respect to the coil portion. The magnet reciprocates between the position of FIG. 4A and the position of FIG. 4B and generates a magnetic field in the coil part to produce electric power.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and will be described below by the person skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of the claims.

The present invention relates to a wave power generator capable of producing electric power by converting the potential energy of a wave into the relative motion of a magnet and a coil, and corresponds to a technology that can be used in a power generation field for producing electric power.
