Description

Power generation device using air pressure inside the hull

[0001] The present invention relates to a power generation device, and more specifically, to a power generation device that generates electricity using air pressure inside an enclosure.

[0002]

[0003] Generally, a generator is a device that receives mechanical energy from an external power source and converts it into electrical energy, and external power sources used include turbines, water turbines, electric motors, and engines.

[0004] Methods of generating electrical energy using external power sources include power generation that directly utilizes natural forces, such as hydroelectric power generation utilizing the difference in water potential energy and wind power generation utilizing the power of wind; additionally, there are thermal power generation and nuclear power generation that generate electricity through artificial methods using natural resources extracted from nature, such as petroleum, coal, or uranium.

[0005] As is well known, the power generation principle of a generator using an external power source as described above is based on the relative relationship between electrons and magnetic fields within a conductor, and when a conductor cuts through magnetic flux, a voltage is induced across the ends of the conductor, and current flows due to the induced voltage.

[0006] At this time, since the magnitude of the induced voltage (E) is related to the magnetic flux density (B), the length (I) of the conductor in the magnetic field, and the speed (V) of the conductor, external power is required for the operation of the generator, and mechanical energy must be continuously supplied from an external power source.

[0007] However, in the case of the aforementioned thermal power generation or nuclear power generation, the generator is operated using thermal energy generated by the combustion of natural resources or nuclear reactions. Consequently, not only is the efficiency of conversion into electrical energy reduced due to the loss of thermal energy, but many environmental problems associated with power generation are also emerging, such as global warming caused by the generation of carbon dioxide from the combustion of fuel, radioactive leakage from nuclear reactions, and the problem of nuclear waste disposal.

[0008] Furthermore, natural resources such as coal and oil, which are representative fossil fuels, have limited reserves and are predicted to deplete their available energy. Consequently, serious energy issues are being raised regarding the need to develop new alternative energy sources due to the trend of continuously rising oil prices. Additionally, there are problems associated with environmental restrictions that accompany the use of natural energy sources such as hydropower, wind power, or solar energy.

[0009]

[0010] The power generation device based on air pressure inside the enclosure according to the present invention aims to solve the following problems in order to solve the aforementioned problems.

[0011] First, the invention provides a power generation device capable of producing electricity in an eco-friendly manner without the need for separate fuel combustion or power devices by utilizing air pressure naturally generated by the movement of a fluid.

[0012] Second, by diversifying the driving method of the generator using air blowout as a power source, it is possible to implement it as a different type of power generation device, such as a turbine generator including a rotating body or a linear generator using linear motion, thereby providing the possibility of selection according to the application environment and requirements.

[0013] Third, by utilizing air jets from both directions for power generation and modularizing multiple hulls to enable expanded operation, the aim is to provide a power generation system that increases power generation efficiency and can respond to various installation conditions.

[0057] Preferred embodiments according to the present invention will be described in detail with reference to the attached drawings, provided that identical or similar components are given the same reference number regardless of the drawing symbols, and redundant descriptions thereof will be omitted.

[0058] Furthermore, in describing the present invention, detailed descriptions of related prior art are omitted if it is determined that such descriptions could obscure the essence of the invention. Additionally, it should be noted that the attached drawings are intended only to facilitate an understanding of the concept of the present invention and should not be interpreted as limiting the concept of the present invention.

[0059]

[0060] Hereinafter, a power generation device based on air pressure inside a housing according to various embodiments of the present invention will be described with reference to the attached drawings.

[0061] The power generation device by air pressure inside the housing according to the present invention is configured to include one or more housings (100) configured to float on the water surface as illustrated in FIG. 1, etc., and a generator (200) that generates electricity.

[0062] The housing (100) is configured to include an internal space (110) formed in a predetermined shape and a fluid (120) filled to flow in the internal space (110).

[0063] The generator (200) is configured to generate electricity using the pressure of air in the internal space (110) formed during the process in which the fluid (120) flows over the internal space (110) of the housing (100).

[0064] In particular, it is desirable that the generator (200) can produce electricity by means of air blowing in both directions, in which the air repeatedly moves alternately in one direction and in the other direction opposite to the one direction.

[0065] For this purpose, a Wells turbine or Impulse turbine type generator designed to rotate only in one direction even with the ejection of air reciprocating in both directions can be considered as the generator (200).

[0066] Hereinafter, a power generation device based on air pressure inside a housing according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 4.

[0067] In the case of a power generation device by air pressure inside a housing according to the first embodiment of the present invention, the housing (100) is configured to include an internal bulkhead (130), a first through hole (141), a second through hole (142), and a first connecting pipe (151) as shown in FIGS. 1 to 4.

[0068] The internal partition (130) is configured to traverse the internal space (110) in either horizontal or vertical direction and protrude downward from the upper side of the internal space (110) by a predetermined height, but not protrude to the bottom of the internal space (110), so that an opening (131) of the partition is formed at the bottom of the internal space (110) that is open by a predetermined height.

[0069] At this time, the fluid (120) is filled to a height higher than the lower end of the inner partition (130), and as a result, the lower end of the inner partition (130) is submerged in the fluid (120) to a depth from the upper end.

[0070] Accordingly, the flow of air between the internal space (110) of the sealed enclosure (100) and the air outside the enclosure (100) is completely blocked, but a first through hole (141) and a second through hole (142) are formed on one side and the other side of the enclosure (100) based on the internal partition (130) to enable bidirectional air flow between the first internal space (111) and the second internal space (112), respectively, and at this time, the air of the first internal space (111) and the air of the second internal space (112) are ejected in opposite directions from the first through hole (141) and the second through hole (142), respectively.

[0071] The first connecting pipe (151) is a tubular configuration in which one side is connected to the first through hole (141) and the other side is connected to the second through hole (142), and the generator (200) is arranged to be connected to a specific part of the first connecting pipe (151).

[0072] Specifically, as shown in FIGS. 1 to 4, the generator (200) may be placed inside the first connecting pipe (141) together with a rotary motion device configured to rotate by the flow of air, such as a blade, or only the rotary motion device may be placed inside the first connecting pipe (151), and the generator (200) connected to the rotary motion device may be placed outside the first connecting pipe (151).

[0073] In this situation, when the hull (100) is placed in a flat state as shown in FIG. 1, the internal space (110) of the hull (100) is divided into a first internal space (111) and a second internal space (112) by an internal partition (130) and a fluid (120).

[0074] At this time, when the housing (100) tilts to the left, the fluid (120) flows to maintain a horizontal position, and as a result, as shown in FIG. 3, the volume of the first internal space (111) decreases and, conversely, the volume of the second internal space (112) increases.

[0075] In this process, the air pressure within the first internal space (111) increases, and the air contained in the first internal space (111) is ejected in the first direction, creating an air ejection (21) that is ejected from the first through hole (141) to the first connecting pipe (151).

[0076] In addition, when the housing (100) is tilted to the right, the volume of the second internal space (112) decreases and the volume of the first internal space (111) increases due to the flow of the fluid (120), as shown in FIG. 4.

[0077] In this process, the air pressure in the second internal space (112) increases, and the air contained in the second internal space (112) is ejected from the second through hole (142) to the first connecting pipe (151), thereby generating a second direction air ejection (22).

[0078] The hull (100) floating on the surface of the sea or the like is repeatedly floated in one direction and the other direction by waves, and as a result, air ejection (21) in the first direction and air ejection (22) in the second direction occur alternately.

[0079] At this time, the generator (200) placed inside the first connecting pipe (151) is configured to produce electricity even with the ejection of air reciprocating in both directions as described above, so it is possible to produce electricity through the first direction air ejection (21) and the second direction air ejection (22).

[0080] Meanwhile, considering the case where air is not ejected because sufficient air is not contained in the internal space (110) of the housing (100), a suction through hole of a predetermined shape may be provided in a predetermined part of the housing (100) near the first through hole (141) and the second through hole (142), and furthermore, it is preferable to attach a one-way check valve to the suction through hole that allows air to flow from the outside of the housing (100) to the inside but blocks the outflow of air from the inside of the housing (100) to the outside.

[0081] Hereinafter, a power generation device based on air pressure inside a housing according to a second embodiment of the present invention will be described with reference to FIG. 5.

[0082] A power generation device based on air pressure inside a housing according to the second embodiment of the present invention is provided with an internal partition (130) as described above inside a housing (100), and a partition penetration device (132) formed to penetrate the internal partition (130) by a predetermined size at a predetermined position above the internal partition (130) so that air can freely flow in both directions between one side and the other side of the internal space (111) of the housing (100).

[0083] At this time, the generator (200) may be placed inside the bulkhead penetration device (132) together with a rotary motion device configured to rotate by the flow of air, such as a blade, or only the rotary motion device may be placed inside the bulkhead penetration device (132), and the generator (200) connected to the rotary motion device may be placed outside the bulkhead penetration device (132).

[0084] Depending on the tilt of the hull (100), air contained in the first internal space (111) may be ejected from the bulkhead penetration device (132) toward the second internal space (112), or a first direction air ejection (21) may be generated, or air contained in the second internal space (112) may be ejected from the bulkhead penetration device (132) toward the first internal space (111), or a second direction air ejection (22) may be generated.

[0085] At this time, the generator (200) connected to the inside of the bulkhead penetration device (132) is configured to produce electricity even with the ejection of air reciprocating in both directions as described above, so it is possible to produce electricity through the first direction air ejection (21) and the second direction air ejection (22).

[0086] Hereinafter, a power generation device based on air pressure inside a housing according to the third embodiment of the present invention will be described with reference to FIG. 6.

[0087] A power generation device based on air pressure inside a housing according to the third embodiment of the present invention is configured to have an internal partition wall (130) as described above inside a housing (100), similar to the power generation device based on air pressure inside a housing according to the second embodiment described above, and to include a partition wall penetration device (132) having a hole that penetrates the internal partition wall (130) of a predetermined size at a predetermined position on the upper side of the internal partition wall (130), and a generator (200) is configured to be connected to the inside of the partition wall penetration device (132).

[0088] At this time, as shown in FIG. 6, a generator (200) may be placed inside the bulkhead penetration device (132) together with a rotary motion device configured to rotate by the flow of air, such as a blade, or only the rotary motion device may be placed in the bulkhead penetration device (132), and the generator (200) connected to the rotary motion device may be placed outside the bulkhead penetration device (132).

[0089] As shown in FIG. 6, a protrusion is formed in the upper middle region of the hull (100), and as a result, a protruding space (113) is formed inside the hull (100), and a bulkhead penetration device (132) is formed within the protruding space (113).

[0090] As a result, since the height of the bulkhead penetration device (132) is positioned higher than the surface of the fluid (120), the inflow of the fluid (120) toward the bulkhead penetration device (132) can be blocked when the hull (100) is tilted at a large angle along one side or the other.

[0091] Depending on the tilt of the hull (100), a first direction air ejection (21) may be generated in which air contained in the first internal space (111) is ejected from the bulkhead penetration device (132) through one side of the protruding space (113) toward the second internal space (112), or conversely, a second direction air ejection (22) may be generated in which air contained in the second internal space (112) is ejected through the other side of the protruding space (113) toward the first internal space (111).

[0092] At this time, the generator (200) connected to the inside of the bulkhead penetration device (132) is configured to produce electricity even with the ejection of air reciprocating in both directions as described above, so it is possible to produce electricity through the first direction air ejection (21) and the second direction air ejection (22).

[0093] A power generation device using air pressure inside a housing according to the fourth embodiment of the present invention is configured such that a separate protruding space (113) is provided on the upper part of the housing (100) as shown in FIG. 7, and a generator (200) is placed within this protruding space (113).

[0094] A generator (200) may be placed within the protruding space (113) together with a rotary motion device such as a blade, or a rotary motion device for driving the generator (200) may be placed within the protruding space (113) and the generator (200) may be placed outside the protruding space (113) in connection with the rotary motion device.

[0095] A pair of protruding through holes (133) are provided for the inflow and outflow of air between the first internal space (111) and the protruding space (113) and the second internal space (112) and the protruding space (113) inside the housing (100).

[0096] In the above structure, depending on the tilt of the housing (100), a first direction air ejection (21) may be generated in which air contained in the first internal space (111) is ejected into the protruding space (113) through the protruding through hole (133) on one side, or conversely, a second direction air ejection (22) may be generated in which air contained in the second internal space (112) is ejected into the protruding space (113) through the protruding through hole (133) on the other side.

[0097] The structure of the power generation device by air pressure inside the housing according to the fourth embodiment of the present invention described above is ultimately a structure based on the same principle as the power generation device by air pressure inside the housing according to the first embodiment of the present invention shown in FIGS. 1 to 4, wherein the two protruding through holes (133) on both sides of FIG. 7 perform substantially the same function as the first through hole (141) and the second through hole (142) of FIGS. 1 to 4, and the middle part of the protruding space (113) of FIG. 7 performs the same function as the first connecting pipe (151) of FIGS. 1 to 4.

[0098] At this time, the generator (200) placed inside the protruding space (113) is configured to rotate only in one direction to produce electricity even with the ejection of air reciprocating in both directions as described above, so that electricity can be produced by the first direction air ejection (21) and the second direction air ejection (22).

[0099] The shape of the housing (100) of the power generation device by air pressure inside the housing according to the first to fourth embodiments of the present invention described above may be formed in a cylindrical shape.

[0100] Hereinafter, a power generation device based on air pressure inside a housing according to the fifth embodiment of the present invention will be described with reference to FIGS. 8 to 11.

[0101] A power generation device based on air pressure inside a housing according to the fifth embodiment of the present invention comprises a housing (100) and a generator (200) as shown in FIGS. 8 to 11, wherein the housing (100) is configured to include one lower housing (100a) and two upper housings (100b, 100c), unlike other embodiments described above.

[0102] Specifically, the lower housing (110) is formed in a predetermined shape to have a predetermined length in each horizontal and vertical direction and a predetermined height in the vertical direction.

[0103] Two upper casings, namely the first upper casing (100b) and the second upper casing (100c), are configured to protrude upwardly so as to face each other on one side and the other side of the lower casing (100a), and are configured so that their interiors communicate with the lower casing (100a).

[0104] That is, the lower housing (100a) and two upper housings (100b, 100c) facing each other are integrated to form a single housing (100), and this housing (100) may be formed in an overall U-shape.

[0105] The fluid (120) is filled to a certain height above the upper surface of the lower housing (100a) or above the upper surface, thereby forming a first internal space (111) inside the first upper housing (100b) of the housing (100) and a second internal space (112) inside the second upper housing (100c).

[0106] In addition, a third through hole (143) and a fourth through hole (144) are formed in the upper portions of the first upper housing (100b) and the second upper housing (100c), respectively. At this time, air can flow in and out between the first internal space (111) and the outside through the third through hole (143), and air can flow in and out between the second internal space (112) and the outside through the fourth through hole (144).

[0107] The second connecting pipe (152) is a tubular configuration in which one side is connected to the third through hole (143) and the other side is connected to the fourth through hole (144), and the generator (200) is arranged to be connected to a specific part of the second connecting pipe (152).

[0108] As shown in FIGS. 8 to 12, the generator (200) may be placed inside the second connecting pipe (152) together with a rotary motion device capable of rotating by the flow of air, such as a blade, or it is also possible to place only the rotary motion device inside the second connecting pipe (152) and place the generator (200) connected to the rotary motion device outside the second connecting pipe (152).

[0109] At this time, when the housing (100) tilts to the left, the fluid (120) flows to maintain a horizontal position, and as a result, as shown in FIG. 10, the volume of the first internal space (111) decreases and, conversely, the volume of the second internal space (112) increases.

[0110] In this process, the air pressure in the first internal space (111) increases, and the air contained in the first internal space (111) is ejected in the first direction, such that the air is ejected from the third through hole (143) to the second connecting pipe (152), thereby generating a first direction air ejection (21).

[0111] In addition, when the housing (100) is tilted to the right, the volume of the second internal space (112) decreases and the volume of the first internal space (111) increases due to the flow of the fluid (120), as shown in FIG. 11.

[0112] In this process, the air pressure in the second internal space (112) increases, and the air contained in the second internal space (112) is ejected in a second direction (22) through the fourth through hole (144) to the second connecting pipe (152).

[0113] At this time, the generator (200) arranged to be connected to the second connecting pipe (152) is configured to produce electricity based on the ejection of air that reciprocates in both directions as described above, so that electricity can be produced by the first direction air ejection (21) and the second direction air ejection (22).

[0114] Meanwhile, considering the case where air is not ejected because sufficient air is not contained in the first internal space (111) and the second internal space (112) of the housing (100), a suction through hole having a predetermined shape may be provided in a predetermined part of the housing (100) near the third through hole (143) and the fourth through hole (144), and furthermore, it is preferable to attach a one-way check valve to the suction through hole that allows air to flow in from the outside of the housing to the inside but blocks the outflow of air from the inside of the housing to the outside.

[0115]

[0116] In addition, to induce more air ejection, it may be considered to generate electricity using a single housing assembly (40) formed by combining multiple housings (100) adjacent to each other as shown in FIGS. 12 and 13.

[0117] That is, as shown in FIG. 12, a housing assembly (40) can be formed by applying a housing (100) of a power generation device by air pressure inside a housing according to the first embodiment of the present invention, and as shown in FIG. 13, a housing assembly (40) can be formed by applying a housing (100) of a power generation device by air pressure inside a housing according to the fifth embodiment of the present invention.

[0118] At this time, a third connecting pipe (153) communicating with one side of the internal space of each housing (100), a fourth connecting pipe (154) communicating with the other side of the internal space of each housing (100), and a fifth connecting pipe (155) having one side communicating with the third connecting pipe (153) and the other side communicating with the fourth connecting pipe are provided, and a generator (200) is arranged to be connected to a predetermined part inside the fifth connecting pipe (155).

[0119] In particular, the generator (200) may be placed inside the fifth connecting pipe (155) together with a rotary motion device capable of rotating by the flow of air, such as a blade, as shown in FIGS. 12 and 13, or it is also possible to place only the rotary motion device inside the fifth connecting pipe (155) and place the generator (200) connected to the rotary motion device outside the fifth connecting pipe (155).

[0120] Through this, the generator (200) is able to produce more electricity by moving the entire air contained in the internal space of multiple enclosures (100) toward one generator (200).

[0121] Hereinafter, with reference to FIG. 14, an example of installation of a power generation device by air pressure inside a housing according to the present invention will be described.

[0122] The power generation device based on air pressure inside the hull according to the present invention is installed to float on the sea surface, and a plurality of power generation devices (1) are configured to generate electricity by driving a generator through air flow caused by air pressure inside the hull while floating on the sea surface.

[0123] At this time, multiple power generation devices (1) are arranged so that the housings (100) are arranged in a long longitudinal direction in the same direction as the direction of the bidirectional air ejection, and adjacent housings can be connected through a connecting member (500), and it is preferable that the connecting member (500) has a rotatable hinge structure.

[0124] Here, the enclosure assembly (40) of FIGS. 12 and FIGS. 13 may be applied to the multiple power generation devices (1).

[0125] In addition, one end of a mooring anchor line (300) made of a predetermined material is attached to one or more locations in the middle of the longitudinal direction of the hull (100), and the other end of the mooring anchor line (300) is fixed to a mooring anchor (400) fixed to the seabed (30), thereby enabling each power generation device (1) to move efficiently left and right.

[0126] As described above, if the power generation device (1) is configured to float on the water surface (10), a separate fixed facility or a separate floating facility may be provided near the power generation device (1), and at this time, the generator (200) may be placed on the fixed facility or the floating facility.

[0127] Furthermore, by placing a solar power generation module on the upper surface of the housing (100), it will be possible to perform not only power generation based on air pressure inside the housing (100) but also power generation based on solar energy.

[0128]

[0129] Hereinafter, a power generation device based on air pressure inside a housing according to the 6th embodiment of the present invention will be described with reference to FIGS. 15 to 19.

[0130] The sixth embodiment of the present invention is provided with a housing (100) that includes an internal partition (130), a first through hole (141), a second through hole (142), and a first connecting pipe (151) connecting them, in the same manner as the first embodiment.

[0131] However, the present embodiment is characterized in that the generator (200) provided in the first connecting pipe (151) is not a turbine type, but a linear generator (250) that converts the linear ejection of air into piston motion to generate power.

[0132] As illustrated in FIG. 15, the linear generator (250) includes a stator (251) positioned along the inner circumference of a first connecting tube (151), a mover (252) that moves in a straight line back and forth inside the stator (251), and a piston (255) coupled to the center of the mover (252).

[0133] The piston (255) has its stroke limited by a first end cap (253) and a second end cap (254) installed at both ends of the first connecting pipe (151), and the end caps may be equipped with an elastic body or a damper to mitigate shock.

[0134] At this time, when the housing (100) tilts to the left, the fluid (120) flows to maintain a horizontal position, and as a result, the volume of the first internal space (111) decreases as shown in FIG. 3 due to the above configuration, and conversely, the volume of the second internal space (112) increases.

[0135] In this process, the air pressure in the first internal space (111) increases, and the air contained in the first internal space (111) is ejected from the first through hole (141) to the first connecting pipe (151), thereby generating a first direction air ejection (21), and as a result, the piston (255) moves to the right as shown in FIG. 16.

[0136] In addition, when the housing (100) is tilted to the right, the volume of the second internal space (112) decreases and the volume of the first internal space (111) increases due to the flow of the fluid (120), as shown in FIG. 4.

[0137] In this process, the air pressure in the second internal space (112) increases, and the air contained in the second internal space (112) is ejected from the second through hole (142) to the first connecting pipe (151), thereby generating a second direction air ejection (22), and as a result, the piston (255) moves to the left as shown in FIG. 17.

[0138] Eventually, the hull (100) floating on the surface of the sea or the like is repeatedly floated in one direction and the other direction by waves, and as a result, air ejection (21) in the first direction and air ejection (22) in the second direction occur alternately.

[0139] The mover (252), which is integrally formed with the piston (255), may include a permanent magnet, and the stator (251) is composed of a coil with a wound wire, so that electromagnetic induction occurs between the stator (251) and the mover (252) during the reciprocating motion of the piston (255). Accordingly, power is generated, and the generated power can be supplied to a load or an energy storage device through an inverter or a converter.

[0140] Accordingly, unlike conventional structures that use only unidirectional airflow, the linear generator (250) of this embodiment can generate power by utilizing both the first direction air blowout (21) and the second direction air blowout (22), and has the advantages of having less wear and noise, a simple structure, and reduced maintenance costs because it does not use a rotating body.

[0141] Meanwhile, the linear generator (250) may have the stator (251) fixedly positioned inside the first connecting pipe (151) as shown in FIG. 16 and FIG. 17, but may also be configured to be connected to a specific part of the first connecting pipe (151) as shown in FIG. 18.

[0142] That is, by combining the stator (251) and the first connecting pipe (151) using a separate connecting member (256), the stator (251) can be easily attached and detached, and as a result, the effect of facilitating installation and replacement of modules is achieved.

[0143] The power generation device based on air pressure inside the housing according to the 6th embodiment of the present invention described above is not limited to the configuration described above and can be implemented with various modifications as follows.

[0144] First, the reciprocating motion of the piston (255) is driven directly by air pressure, but the first end cap (253) and the second end cap (254) may be further equipped with a return means such as a spring, an air cushion, or a magnetic repulsion magnet so that the piston can stably return to its original position after the stroke.

[0145] This restoration means increases stability so that the piston (255) can always reciprocate within a certain range, even in situations where the amplitude of the waves is irregular or the amount of air ejected is momentarily low.

[0146] Second, since heat may be generated in the stator (251) and mover (252) during the repetitive reciprocating motion of the linear generator (250), it may be configured to allow liquid or air cooling by providing heat dissipation fins or heat dissipation holes on the outer surface of the stator (251) or by forming a cooling channel inside the winding section.

[0147] In some cases, a natural cooling method can also be applied by utilizing a portion of the air flowing through the first connecting pipe (151) as cooling air.

[0148] Third, for controlling the linear generator (250), a position sensor for detecting the position of the piston (255) and a flow sensor for detecting the amount of air ejected inside the first connecting pipe (151) may be provided.

[0149] The outputs of these sensors are transmitted to a control module, which can analyze piston motion characteristics based on air ejection direction, size, and period in real time and control the conversion efficiency of power generation output to optimize it.

[0150] Furthermore, sensor information can be transmitted to an energy storage device or a smart control system connected to an external power grid, and can also be utilized for energy management and predictive control.

[0151] Fourth, the structure of the linear generator (250) can also be varied in many ways. For example, the stator (251) can be integrated by winding the coil directly onto the inner wall of the first connecting tube (151), or conversely, it can be housed in a separate housing and connected to the first connecting tube in a modular manner.

[0152] The mover (252) can also be formed in a polygonal cross-sectional structure, a separable magnet combination structure, etc., in addition to a cylindrical shape. A wear-resistant coating, a low-friction liner, or a magnetic levitation structure can be applied to the outer surface of the piston (255) to reduce friction loss and increase durability.

[0153] Fifth, the linear generator (250) may be installed as a single module along the entire length of the first connecting pipe (151), but may also be configured as a multi-stage power generation structure by arranging multiple unit generator modules in series or in parallel.

[0154] In this case, each module can be independently detached through the connecting member (256), so partial replacement or maintenance is easy as needed.

[0155] Sixth, in addition to simply converting the generated power into alternating current through an inverter, it can be directly connected to energy storage devices such as batteries and supercapacitors, or integrated into a hybrid power management system; as a result, the present invention can be applied to a wide range of applications, from small-scale distributed power generation facilities to large-scale offshore plant power generation systems.

[0156] Accordingly, the sixth embodiment of the present invention is based on the basic principle of linear motion driving of a linear generator by air ejection, while also ensuring power generation efficiency, durability, maintainability, and scalability through various return means, cooling means, sensor and control technologies, structural modifications, modular configurations, etc.

[0157] In addition, as shown in FIG. 19, a power generation device can be considered that applies a housing assembly formed by adjacently combining a plurality of housings (100) of the sixth embodiment of the present invention.

[0158] At this time, a plurality of casings (100) are arranged adjacent to each other, and the first connecting pipe (151) of each casing (100) is connected to the third connecting pipe (153) on one side and the fourth connecting pipe (154) on the other side, respectively. The third connecting pipe (153) and the fourth connecting pipe (154) are again connected to the fifth connecting pipe (155), and a linear generator (250) is installed at a predetermined location on the fifth connecting pipe (155).

[0159] According to this configuration, the air pressure generated in the internal space (110) of each hull (100) is ejected through the first through hole (141) or the second through hole (142) into the first connecting pipe (151), and then concentrated into the fifth connecting pipe (155) through the third connecting pipe (153) and the fourth connecting pipe (154).

[0160] Therefore, air ejections generated from multiple hulls are concentrated into a single fifth connecting pipe (155), which can impart greater kinetic energy to the piston (255), and thus increase the power output compared to a single hull structure.

[0161] Additionally, only one linear generator (250) may be installed in the fifth connecting pipe (155), but if necessary, multiple linear generators (250) may be arranged in series or in parallel to implement a multi-stage power generation structure.

[0162] In this case, each linear generator (250) can be driven independently or operated complementarily to ensure both stability and scalability of power production.

[0163] Therefore, the multi-hull assembly structure shown in Fig. 19 has the advantage of being able to configure a large-capacity power generation system by expanding the hulls in modular units when installed in a wide body of water such as a marine environment, and at the same time, maintenance of each module can be performed individually.

[0164] Hereinafter, a power generation device by air pressure inside a housing according to the seventh embodiment of the present invention will be described with reference to FIGS. 20 and 21.

[0165] The power generation device according to the seventh embodiment of the present invention includes a first upper housing (100b) and a second upper housing (100c) formed to face each other on both sides of a lower housing (100a), in the same manner as the power generation device according to the second embodiment of the present invention.

[0166] In the internal space (111) of the first upper housing (100b) and the internal space (112) of the second upper housing (100c), air pressure is generated according to the flow of the fluid (120), and these are ejected into the second connecting pipe (152) through the third through hole (143) and the fourth through hole (144).

[0167] In this embodiment, a linear generator (250) is installed in the second connecting pipe (152), and the piston (255) moves in a reciprocating linear motion according to the ejection of air in both directions, and accordingly, electromagnetic induction occurs between the stator (251) and the mover (252) to generate power.

[0168] The specific configuration, operating principle, and effects of the linear generator (250) have been described in detail in the 6th embodiment, so the redundant description is omitted in this embodiment.

[0169] FIG. 21 illustrates an example of application of a housing assembly formed by adjacently combining a plurality of housings (100) of a power generation device according to the seventh embodiment of the present invention.

[0170] The air ejection generated from the multiple casings (100) flows into the second connecting pipe (152) through the third through hole (143) and the fourth through hole (144), and these are concentrated to drive the linear generator (250).

[0171] Therefore, even when expanded to a multi-module structure, power generation output is increased compared to a single module, and an efficient and stable power supply system can be established by arranging multiple linear generators in series or parallel as needed.

[0172]

[0173] Various embodiments of a power generation device based on air pressure inside a housing according to the present invention have been described above.

[0174] The first to seventh embodiments of the present invention do not each represent independent configurations, but can be implemented in various modified forms by selectively combining or sharing technical features from one another.

[0175] For example, in an embodiment applying a turbine generator, the configuration of a linear generator may be partially adopted, and conversely, in an embodiment of a linear generator, structural elements of a turbine generator may be applied in parallel.

[0176] Therefore, the present invention is not limited to the embodiments described above, and it goes without saying that all forms that a person skilled in the art can easily modify or apply within the technical scope of the present invention are included within the scope of the rights of the present invention.
