Description

wind turbine

[0001] The present invention relates to a wind power generation device, and more particularly, to a wind power generation device capable of improving power generation efficiency.

[0002] In general, a wind turbine is a device that converts rotational energy into electrical energy by rotating blades using the wind pressure. Its structure is simple and installation is easy, so its use has been increasing recently.

[0003] These wind power generators are composed of a housing, blades that are rotatably installed inside the housing and rotate by wind pressure, a generator that is installed inside the housing and converts the rotational energy of the blades into electrical energy, and a capacitor that charges the electrical energy transmitted from the generator.

[0004] However, conventional wind turbines have a structure that makes it difficult to rotate the blades at a high speed because a large amount of wind flowing into the interior of the housing flows out through the exterior of the housing, and the power generation efficiency is not good because the wind flowing into the interior of the housing does not flow quickly.

[0005] A prior art document related to the present invention is Republic of Korea Patent Publication No. 10-2406742 (June 2, 2022), which discloses a bidirectional vertical wind turbine.

[0006] The purpose of the present invention is to provide a wind power generation device capable of improving power generation efficiency.

[0007] A wind power generator according to the present invention comprises a frame part having an inner working chamber opened to an edge, a rotating part rotatable based on a vertical rotation center of the working chamber, a plurality of blade parts vertically coupled along a radial direction of the rotating part and rotated by the force of wind acting on one surface, a plurality of guide parts vertically coupled along an edge of the working chamber and having outer and inner surfaces inclined toward a rotation path of the blade parts, and a power generation part that converts rotational force transmitted from an axial direction of the rotating part into electric energy, wherein the guide part is characterized in that the inner surface facing the working chamber guides wind introduced into the rotation path inclined toward the rotation direction of the blade parts.

[0008] In addition, the wing portion may include a body whose rear surface is connected to the rotating portion and whose front surface facing the edge of the operating room is formed to be concave in the rear while forming a surface in the rotational direction, and a bending section that is bent to form a surface in the reverse direction from one end of the body in the rotational direction and is positioned between the guide portion and the body.

[0009] In addition, the guide portion may be formed convexly with the inner surface curved on both sides in the width direction, and may be formed concavely with the outer surface curved on both sides in the width direction.

[0010] In addition, the frame part may further include an upper passage extending vertically through the upper surface, an upper support part positioned in the central region of the upper passage and having an upper end of the rotation part rotatably coupled to a lower surface thereof, a lower passage extending vertically through the lower surface of the frame part, a lower support part positioned in the central region of the lower passage and having an upper end of the rotation part rotatably coupled to a lower surface thereof, a plurality of upper auxiliary guide parts having a radial length of the upper support part and having widthwise opposite sides formed to be inclined downward in the rotational direction of the wing part, and a plurality of lower auxiliary guide parts having a radial length of the lower support part and having widthwise opposite sides formed to be inclined upward in the rotational direction of the wing part.

[0011] In addition, it further includes a plurality of inflow guides arranged in a spaced manner along the outer periphery of the frame portion and having a vertical length, and the inflow guides can guide wind through the gaps between them and introduce it into the operating room.

[0012] The present invention has the effect of improving power generation performance by amplifying the rotational speed of the wind by centrifugal force and providing acceleration, minimizing heat generation of the device by reducing the load resistance of the wind by the guide portion, and increasing the power generation amount by amplifying the strength and speed of the wind by using the inflow guide portion.

[0039]

[0040] Referring to FIGS. 1 to 17, a wind power generator according to the present invention is for converting kinetic energy of wind (A) into electrical energy, and may include a frame portion (100), a rotating portion (200), a plurality of wing portions (300), a plurality of guide portions (400), and a power generation portion (500).

[0041] The frame part (100) has an operating room (110) formed therein so that the rotating part (200) and the wing part (300) can be rotatably installed, and the edge of the frame part (100) is horizontally open so that wind (A) can communicate. Here, the frame part (100) may have a cylindrical shape with the edge forming a circle.

[0042] In addition, the lower part of the frame part (100) can be fixedly connected to the installation surface, but can be installed in a spaced state on the upper part of the installation surface by a separate support frame (101). Of course, the structure for fixing the frame part (100) to the installation surface can be applied in various ways as needed.

[0043] Additionally, the frame portion (100) may include an upper frame positioned at the top and having a circular edge, and a lower frame positioned corresponding to the lower portion of the upper frame and having a circular edge.

[0044] In this case, the lower part of the lower frame may be fixedly connected to the installation surface, but may be installed in a spaced state on the upper part of the installation surface by a separate support frame (101). Of course, the structure for fixing the lower frame to the installation surface can be applied in various ways as needed.

[0045] The rotating part (200) is configured to be rotatably coupled to the wing part (300), and is provided to be rotatable based on the vertical rotation center of the operating room (110). The rotating part (200) can be installed at the center position of the operating room (110), and the radial direction of the rotating part (200) can form a circle.

[0046] In addition, the upper and lower ends of the rotating part (200) can be horizontally rotatably coupled to the upper and lower surfaces of the operating room (110), respectively, and bearings (not shown) can be coupled to the upper and lower surfaces of the operating room (110), respectively, and the upper and lower ends of the rotating part (200) can be rotatably supported by being coupled to the bearings, respectively.

[0047] The wing part (300) is configured to be rotated by the wind (A) flowing into the operating room (110), and is vertically coupled along the radial direction of the rotating part (200) and rotated horizontally by the force of the wind (A) acting on the front. Here, the wing part (300) has a length in the vertical direction.

[0048] To explain in more detail, the wing part (300) may include a body (310) whose rear side is connected to the rotating part (200), whose front side facing the edge of the operating room (110) is formed to be concave in the rear while forming a surface in the rotational direction, and a bending section (320) that is bent to form a surface in the reverse direction from one end of the body (310) in the rotational direction and is positioned between the guide part (400) and the body (310).

[0049] The body (310) has a width set in the rotational direction of the rotating part (200) and a length vertically up and down, and the rear surface of the body (310) can be coupled in the radial direction of the rotating part (100) by one or more supports.

[0050] Here, the body (310) can be spaced apart in a number of equal intervals (e.g., four) along the radial direction of the rotating part (200), and the front surface of the body (310) can face the edge of the operating chamber (110), and the front surface of the body (310) is formed to be concave toward the rear while forming a curved surface in the direction of rotation, so that the wind (A) flowing in from the edge of the operating chamber (110) can move in the direction of rotation along the front surface of the body (310).

[0051] The bending section (320) is a section where the resistance of wind (A) flowing in diagonally through the edge of the operating room (110) acts, and is bent to form a surface in the direction opposite to the direction of rotation from one end of the rotational direction side of the body (310).

[0052] At this time, the end of the bending section (320) is positioned in the gap between the body (310) and the guide part (400), and the inner bending surface of the bending section (320) is connected to the front surface of the body (310) while forming a curved surface.

[0053] For example, when wind (A) is introduced from the edge of the operating room (110), the wind (A) moves in the rotational direction along the front of the body (310) and collides with the inner folded surface of the bending section (320), and the wing section (300) rotates due to the force acting on the inner folded surface of the bending section (320).

[0054] The guide section (400) is configured to introduce wind (A) blowing from the outside of the frame section (100) in a diagonal direction, and is vertically coupled along the edge of the operating room (110), and both sides in the width direction form an angle inclined toward the rotation path of the wing section (300).

[0055] At this time, the outer surface (420) of the guide portion (400) facing the outside of the frame portion (100) and the inner surface (41) of the guide portion (400) facing the operating room (110) are formed to be inclined toward the rotation path of the wing portion (300), and both sides of the width direction of the frame portion (100) can form an angle of 15 degrees or less with respect to the edge of the operating room (110), but the angle of the frame portion (100) can be applied in various ways as needed.

[0056] In addition, the guide portion (400) may be formed convexly with the inner surface (410) curved on both sides in the width direction, and may be formed concavely with the outer surface (420) curved on both sides in the width direction. In this case, the wind (A) moving into the interior of the operating chamber (110) may be guided in a curved manner by the inner surface (410) and may be introduced to the edge of the operating chamber (110).

[0057] For example, when wind (A) flows in from the edge of the operating room (110), the wind (A) is guided along the inner surface (410) of the guide section (400) and moves diagonally toward the edge of the operating room (110), and the wind (A) moved to the edge of the operating room (110) moves in the rotational direction along the front surface of the body (310) and collides with the inner folded surface of the bending section (320).

[0058] At this time, the wing part (300) rotates due to the force acting on the inner folded surface of the bending section (320), and the wind (A) moving to the edge of the operating room (110) rotates along the rotation path of the wing part (300) while being guided along the inner surface of the guide part (400), and the rotation part (200) rotates due to the rotation of the wing part (300) and transmits rotational power to the power generation part (500) to be described later.

[0059] That is, since the wind (A) moving from the outside of the frame part (100) to the edge of the operating room (110) is guided by the inclined inner surface of the guide part (400), the wind (A) guided by the guide part (400) can rotate without being directly discharged through the outside of the operating room (110), and since the wind (A) moves at a high speed by centrifugal force, the rotation speed of the wind (A) can be amplified, thereby improving the power generation efficiency.

[0060] The power generation unit (500) is configured to convert the rotational force transmitted from the axial direction of the rotating unit (100) into electrical energy, and is coupled to the lower part of the frame unit (100) and can be mechanically connected to one axial side of the rotating unit (200).

[0061] Here, the power generation unit (500) may include a housing coupled to the lower part of the frame unit (100), a stator fixedly installed inside the housing and having a coil wound on the outside, a rotor arranged inside or outside the stator and rotatable based on a horizontal center of rotation in the front-back direction, generating electric energy by forming a magnetic field through interaction with the stator (electromagnetic induction: induced current), and a power conversion unit electrically connected to the coil of the stator and converting (DC / AC) power transmitted from the coil.

[0062] In addition, the power conversion unit of the power generation unit (500) may be electrically connected to the storage unit (510) so that electric energy can be charged, and the power conversion unit and the storage unit (510) may be electrically connected to a control unit (not shown) for monitoring the amount of power generated, etc.

[0063] A wind power generator according to one embodiment of the present invention comprises, as shown in FIGS. 5 to 9, an upper passage (120) extending vertically through the upper surface of a frame portion (100), an upper support portion (130) positioned in the central region of the upper passage (120) and having an upper end of a rotating portion (200) rotatably coupled to a lower surface thereof, a lower passage (140) extending vertically through the lower surface of the frame portion (100), a lower support portion (150) positioned in the central region of the lower passage (140) and having an upper end of a rotating portion (200) rotatably coupled to an upper surface thereof, a plurality of upper auxiliary guide portions (160) having a radial length of the upper support portion (130) and having both widthwise sides inclined downward in the rotational direction of the blade portion (300), and a plurality of lower auxiliary guide portions (160) having a radial length of the lower support portion (150) and having both widthwise sides inclined upward in the rotational direction of the blade portion (300). A guide section (170) may be further included.

[0064] The upper passage (120) and the lower passage (140) are opened vertically to allow wind (A) blowing from an oblique direction to flow in, and the upper support (130) and the lower support (150) are positioned correspondingly in the vertical direction so that the upper and lower ends of the rotating part (200) can be connected to enable horizontal rotation.

[0065] In this case, bearings (not shown) can be respectively coupled to the lower surface of the upper support member (130) and the upper surface of the lower support member (150), and the upper and lower surfaces of the rotating member (200) can be respectively coupled to the bearings and supported rotatably.

[0066] The upper auxiliary guide portion (160) is arranged radially in multiple numbers based on the vertical rotation center of the rotating portion (200), and the wind (A) moves downward through the gap between the inner and outer surfaces facing the rotation direction of the wing portion (300), and the wind (A) that moves downwardly at an angle rotates along the rotation path of the wing portion (300).

[0067] At this time, the wind (A) moving along the edge of the operating room (110) is guided along the inner surface of the guide part (400) and the inner surface of the upper auxiliary guide part (160) and rotates along the rotation path of the wing part (300), and the rotation part (200) rotates by the rotation of the wing part (300) and transmits rotational power to the power generation part (500) to be described later. In other words, the amount of air (A) flowing in can be increased, and since the wind (A) rotates at a high speed by centrifugal force, the power generation efficiency can be improved.

[0068] The lower auxiliary guide part (170) is configured to correspond to the lower part of the upper auxiliary guide part (160), and is arranged in a radial manner in a number of portions based on the vertical rotation center of the rotating part (200), and the wind (A) moves upward through the gap between the inner and outer surfaces facing the rotation direction of the wing part (300), and the wind (A) that moves upwardly in an inclined manner rotates along the rotation path of the wing part (300).

[0069] At this time, the wind (A) moving along the edge of the operating room (110) is guided along the inner surface of the guide part (400) and the inner surface of the lower auxiliary guide part (170) and rotates along the rotation path of the wing part (300), and the rotation part (200) rotates by the rotation of the wing part (300) and transmits rotational power to the power generation part (500) to be described later. In other words, the amount of air (A) flowing in can be increased, and since the wind (A) rotates at a high speed by centrifugal force, the power generation efficiency can be improved.

[0070] Meanwhile, a wind power generator according to one embodiment may further include a plurality of inflow guides (600) having vertical lengths and arranged spaced apart along the outer periphery of a frame portion (100) as shown in FIGS. 10 to 12.

[0071] The inflow guides (600) can be arranged in multiple radial directions on the frame portion (100) based on the vertical rotation center of the rotating portion (200), and the inflow guides (600) can be formed with a constant width on both sides in the width direction. Here, the inflow guides (600) can be vertically attached to the edge of the frame portion (100) or spaced apart at a set interval so that one side in the width direction is parallel to the vertical rotation center of the rotating portion (200).

[0072] Since the inflow guide part (600) has a function of collecting wind (A) blowing from the outside, the wind (A) can be concentrated at the intervals between the guide parts (400), and the wind (A) is collected and guided to the operating room (110), thereby improving power generation efficiency.

[0073] In addition, a tapered portion (610) whose width gradually decreases in the direction opposite to the frame portion (100) may be formed on one side of the inflow guide portion (600) in the width direction opposite to the frame portion (100), and the tapered portion (610) may have a length in the vertical direction of the inflow guide portion (600).

[0074] In this case, the air moving into the operating room (110) through the gap between the inlet guides (600) can be guided by the taper section (610) and moved into the operating room (110), thereby reducing vibration and noise caused by the collision of the wind (A).

[0075] Meanwhile, a wind power generator according to one embodiment of the present invention may have a plurality of frame parts (100) arranged in a single row or in multiple columns as shown in FIGS. 13 and 14, and may further include a plurality of inflow guide parts (600) arranged spaced apart along the outer periphery of the frame parts (100) and having a vertical length.

[0076] In this case, the frame parts (100) are installed at the same height so that one side can face each other, and a gap can be formed on the facing side so that the wind (A) can pass through, and the wing parts (300) installed inside the frame parts (100) are provided correspondingly so that they can rotate in opposite directions.

[0077] For example, wind (A) guided through the gaps between the inflow guide parts (600) can pass through the gaps between the frame parts (100), and wind (A) passing through the gaps between the frame parts (100) is introduced to the edge of the operating room (110) through the gaps between the guide parts (400), and the wing parts (300) corresponding to both sides can rotate in opposite directions to simultaneously rotate each rotating part (200).

[0078] That is, since the inflow guide parts (600) collect the wind (A) blowing from the outside and concentrate it in the gaps between the frame parts (100), the amount of wind (A) flowing in can be increased, and since the wind (A) is collected and the corresponding wing parts (300) are rotated simultaneously, the power generation efficiency can be improved.

[0079] In addition, a wind power generator according to one embodiment may be provided such that the inflow guide (600) can be horizontally rotatable by a rotation support (700) as shown in FIGS. 15 to 17, and the rotation support (700) can be provided such that it can be rotatable around a vertical rotation center.

[0080] The rotation support member (700) can be horizontally rotatably coupled to the upper part of the frame member (100) or a separate structure on one side, and the opposite side can be coupled to at least one of the upper and lower parts of the inflow guide member (600).

[0081] For example, one side of the rotation support (700) may be vertically connected to the upper side of the upper support (130) described above and may be provided so as to be capable of horizontal rotation, and the other side may be first bent horizontally to the outer side of the frame (100) and then secondarily bent downwards to be connected to the upper side of the inflow guide (600).

[0082] In another form, one side may be vertically joined to the lower surface of a structure located on the upper side of the frame part (100) and may be provided so as to be capable of horizontal rotation, and the other side may be first bent horizontally to the outer side of the frame part (100) and then secondarily bent downwards to be joined to the upper side of the inflow guide part (600).

[0083] That is, since the inflow guide part (600) can be rotated by the rotation support part (700), the inflow guide part (600) can face the direction in which the wind (A) blows, and the wind (A) is collected in the direction in which the wind (A) blows and concentrated at the edge of the frame part (100), thereby improving the power generation efficiency.

[0084] As a result, the present invention can improve power generation performance by amplifying the rotational speed of the wind by centrifugal force and providing acceleration, minimize heat generation of the device by reducing the load resistance of the wind by the guide part (400), and increase power generation by amplifying the strength and speed of the wind by using the inflow guide part (600).

[0085] Although specific embodiments of the wind power generator according to the present invention have been described so far, it is obvious that various modifications are possible within the scope of the present invention.

[0086] Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims described below but also by equivalents of the claims.

[0087] That is, it should be understood that the above-described embodiments are exemplary in all respects and not restrictive, and the scope of the present invention is indicated by the claims to be described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.

[0088] The mode for carrying out the invention has been described together with the best mode for carrying out the invention above.

[0089] The present invention can improve power generation performance by amplifying the rotational speed of wind by centrifugal force and imparting acceleration, minimize heat generation of the device by reducing the load resistance of the wind by the guide portion, and can amplify the strength and speed of the wind by using the inflow guide portion, so it has industrial applicability.
