Description

Power generation device capable of efficient use of space

[0001] The present invention relates to a power generation device capable of efficient space utilization, and more specifically, to a power generation device capable of efficient space utilization that maximizes operational efficiency through long-term operating cost reduction and flexibility for system expansion or modification by eliminating a structure in which an acceleration means for adding rotational force to a drive shaft is horizontally extended and directly connected to the drive shaft, and by adopting a structure in which the acceleration means is vertically arranged relative to the drive shaft, thereby suppressing the lengthening of the structure in the front-to-back direction when extended, thus utilizing a limited installation space more efficiently, and ensuring maintenance efficiency by improving accessibility, and furthermore, maintaining stability while increasing the density of power generation facilities.

[0002] A power generation device is a device that converts mechanical energy into electrical energy. It generates current through electromagnetic induction between a rotating rotor and a stationary stator, primarily producing electricity using external power sources such as turbines, engines, hydropower, and wind power. It is utilized not only for industrial, commercial, and residential power supply but also for emergency power systems and mobile power supply units.

[0003] Power generation devices can play a role in supplying electricity in various fields; notably, they are used in hospitals, data centers, airports, and telecommunications facilities to maintain a stable power supply even during power outages, and are integrated with automatic switching devices to ensure immediate power delivery.

[0004] In addition, at industrial and construction sites, it enables smooth operations by supplying power necessary for machinery, equipment, and lighting in areas with insufficient power infrastructure.

[0005] Furthermore, it enables sustainable power supply by converting and storing energy produced in conjunction with wind, hydroelectric, and solar power generation systems into electrical energy, serves as an internal power source within vehicles such as ships, railways, and aircraft, and provides both power and electricity simultaneously when integrated with electric propulsion systems.

[0006] In addition, portable generators can be used to provide essential power, such as for charging electronic devices or lighting, for purposes such as camping, military operations, and disaster response.

[0007] Meanwhile, power generation devices used in facilities designed to ensure a stable power supply for large-scale facilities or infrastructure and to meet high power demand are necessarily large-scale.

[0008] The scaling up of power generation equipment is an essential process for increasing electricity production. To supply the large-scale power required by power plants, large-scale equipment capable of converting more energy at once is necessary, thereby maximizing the efficiency of the power plant.

[0009] However, as power generation devices become larger, the installation footprint increases, making it difficult to introduce them into existing facilities. Furthermore, building power plants or power infrastructure requires a larger site, leading to higher construction costs, and placement becomes challenging in urban areas or limited spaces.

[0010] In particular, large-scale power generation units are designed to be excessively long to meet structural and functional requirements for securing higher efficiency and output capacity and adapting to various operating conditions. This structural characteristic presents a structural disadvantage in terms of space utilization, and there is a growing need to address these structural issues of power generation units.

[0014] The present invention was created to address the various problems of the aforementioned prior art. Its purpose is to provide a power generation device capable of efficient space utilization that maximizes operational efficiency by eliminating a structure in which an acceleration means for adding rotational force to a drive shaft is horizontally connected to the drive shaft and adopting a structure in which the acceleration means is vertically arranged relative to the drive shaft, thereby utilizing limited installation space more efficiently to maximize space utilization, improving accessibility to ensure maintenance efficiency, and further increasing the density of power generation facilities while maintaining stability, resulting in long-term operating cost reduction and flexibility for system expansion or modification.

[0015] The present invention is characterized by comprising, as a means to achieve the above objective, a drive shaft extending long in the front and rear directions; a flywheel mounted on the outside of the drive shaft; a generator connected to the front end of the drive shaft and generating power using the rotational force of the drive shaft; a speed sensor for measuring the rotational speed of the drive shaft; a brake module connected to the rear end of the drive shaft and performing rotational braking of the drive shaft when the rotational speed of the drive shaft measured by the speed sensor exceeds a preset rotational speed; and an acceleration unit selectively contacted to the flywheel to provide rotational force to the flywheel.

[0016] In addition, the flywheel comprises a disc having a circular structure with a shaft coupling hole formed through the center and gear teeth formed on its circumferential surface; and the acceleration member is installed at a position contacting the disc in a tangential direction and is characterized by providing rotational force to the disc while reciprocating in a direction perpendicular to the rotational direction of the disc.

[0017] Additionally, the acceleration member is characterized by comprising: a translational member that is rotatably installed at one end on the lower part of the disk and has a free end at the other end, and rotates the disk by reciprocating and extending left and right toward the gear teeth of the disk; and a separation member that reciprocates up and down while connected to the other end of the translational member to separate the translational member engaged with the disk from the disk.

[0018] Additionally, the translational member comprises: a first actuator that is installed to rotate in place at a certain distance eccentrically offset from the disk in the left-right direction and operates to extend and retract; and a first operating bar that forms a long rod structure extending left and right, with one end connected to the first actuator and the other end forming a free end, and has a gear tooth formed on its upper surface that meshes with a gear tooth formed on the disk, and reciprocates left and right according to the extension and retraction operation of the first actuator, separates from the disk when moving to the left, and meshes with the disk when moving to the right, thereby providing linear motion as rotational motion of the disk.

[0019] Additionally, the above separation member comprises: a second actuator installed at a position eccentrically offset from the lower part of the first operating bar and extending vertically and having a first hinge member at the top; and a guide block integrally provided with a second hinge member that is rotatably connected to the first hinge member of the second actuator, has a hollow tube structure through which the first operating bar passes, and is rotatably connected to the first hinge member downwardly; wherein when the guide block moves downward by the second actuator, the first operating bar is forcibly pulled downward to be separated from the disk.

[0020] The present invention eliminates a structure in which an acceleration means for adding rotational force to a drive shaft is horizontally connected to the drive shaft and adopts a structure in which the acceleration means is vertically arranged relative to the drive shaft. By doing so, it maximizes space utilization by using limited installation space more efficiently, ensures maintenance efficiency by improving accessibility, and further provides advantageous effects that maximize operational efficiency through long-term operating cost reduction and flexibility for system expansion or modification, by allowing for increased density of power generation facilities while maintaining stability.

[0035] To fully understand the present invention, preferred embodiments of the invention are described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more completely explain the present invention to those with average knowledge in the art. Accordingly, the shapes of elements in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that in each drawing, identical components may be depicted with the same reference numeral. Detailed descriptions of known functions and configurations that are deemed to unnecessarily obscure the essence of the present invention are omitted.

[0036] Before providing a detailed explanation, for the convenience of explanation, if we specify a non-strict directional standard by referring to the attached drawings, the up and down (y), left and right (x), and front and back (z) are divided as shown in Figure 3, and the direction is specified according to this standard in the explanation related to other drawings as well.

[0037] The power generation device according to the present invention can be broadly defined as comprising a drive shaft (10), a flywheel (100), a generator (20), a speed sensor (30), a brake module (40), and an acceleration unit (200).

[0038] First, the drive shaft (10) can be installed so that its axial direction is parallel to the front and back within the installation space where the power generation device is to be built, and so that it can rotate in place.

[0039] The drive shaft (10) can be supported at a certain height above the installation ground through a support structure (support frame) of the flywheel (100) to be described later, and the flywheel (100), generator (20), speed sensor (30), brake module (40), etc. can be connected to the drive shaft (10) at appropriate locations to perform power generation.

[0040] The flywheel (100) is mounted on the outside of the drive shaft (10) and performs functions such as maintaining the stability of the rotational movement of the drive shaft (10), storing and releasing energy, mitigating vibration and shock, and responding to load fluctuations.

[0041] The above drive shaft (10) and flywheel (100) form a single module (M), and multiple such modules (M) can be connected in a row to realize a power generation device.

[0042] At this time, a chain coupler (CC) for connecting the drive shafts (10) can be installed between adjacent drive shafts (10) between modules (M).

[0043] A chain coupler (CC) is a mechanical element that connects two adjacent drive shafts (10) to transmit power. By adopting a flexible connection method using a chain, it absorbs positional deviations between the drive shafts (10) and enables smooth power transmission.

[0044] The chain coupler (CC) includes a connecting shaft, a roller chain, and a protective cover. The connecting shaft is attached to each drive shaft and interlocks with the roller chain to transmit rotational power. The roller chain maintains constant tension and engages with the sprocket teeth provided on the connecting shaft to smoothly transmit power, and also performs the function of correcting minute alignment deviations between the drive shafts (10). The protective cover prevents the loss of lubricant from the chain and prevents the intrusion of external foreign matter, thereby increasing durability.

[0045] When connecting segmented drive shafts (10) using a chain coupler (CC), if the chain coupler (CC) or the drive shaft (10) is connected with a certain angle phase difference, time difference operation between adjacent flywheels (100) linked to each drive shaft (10) can be induced.

[0046] The above chain coupler (CC) may utilize various known structures, and since various coupler methods may be used to the extent that performance can be maintained at an equivalent standard, a detailed description below is omitted.

[0047] Accordingly, when viewed as an overall system, a plurality of flywheels (100) may be installed at equal intervals along the front and rear axial directions with respect to drive shafts (10) connected coaxially with each other, and a generator (20) may have a structure that is connected to the front end of at least one of the drive shafts (10) and performs power generation using the rotational force output from the drive shaft (10).

[0048] A brake module (40) is installed at the rear end of the drive shaft (10) to provide braking force for controlling the rotational speed of the drive shaft (10).

[0049] The speed sensor (30) can be implemented using known optical sensors, Hall sensors, magnetic induction sensors, etc., for measuring the rotational speed of the drive shaft (10), and its installation location is not particularly limited as long as it can measure the rotational speed of the drive shaft (10) in real time.

[0050] The brake module (40) performs the role of providing stability during the operation of the power generation device by performing rotational braking of the drive shaft (10) when the rotational speed of the drive shaft (10) measured by the speed sensor (30) changes to a preset rotational speed.

[0051] The brake module (40) can suppress unnecessary rotational inertia of the drive shaft (10) when the generator (20) needs to stop, and in particular, in order to prevent overspeed and overload of the drive shaft (10) in the high-speed rotational region of the drive shaft (10), it limits the rotational speed of the drive shaft (10) when the rotational speed exceeds a set limit, thereby preventing mechanical damage to the drive shaft and its connecting system and reducing the overload of the internal parts of the generator (20).

[0052] In addition, the brake module (40) can perform an emergency braking function when the generator (20) needs to stop in an emergency, thereby preventing safety accidents and enhancing protection of the generator (20) and surrounding equipment.

[0053] In addition, the brake module (40) stably fixes the drive shaft (10) to support inspection work of the power generation device, thereby providing the effect of making maintenance work safer and more efficient.

[0054] The brake module (40) can be implemented in various ways, such as known mechanical brakes, hydraulic brakes, electromagnetic brakes, pneumatic brakes, etc., in connection with the drive shaft (10) directly or indirectly to provide braking force, so a detailed description is omitted.

[0055] Next, the acceleration unit (200) is selectively connected in contact with at least one of the plurality of flywheels (100) to provide rotational force to the flywheel (100).

[0056] That is, when the flywheel (100) rotates at a high speed, the acceleration unit (200) does not particularly intervene, but when the drive shaft (10) decelerates to a speed below an appropriate rotational speed, the acceleration unit (200) acts directly on the flywheel (100) to provide additional rotational force.

[0057] Additionally, the acceleration unit (200) plays a role in helping the drive shaft (10) rotate during initial operation, or in supplying auxiliary power at low speeds to maintain a constant rotational speed of the drive shaft, and in providing additional rotational power when necessary to maintain a stable rotational speed in response to instantaneous load changes, thereby providing auxiliary power to help the drive shaft (10) rotate more efficiently.

[0058] Meanwhile, it has been previously mentioned that the power generation efficiency of a power generation device of this structure improves as it becomes longer. In this regard, as shown in FIG. 1, a structure can be considered in which a maximum drive shaft (10) is installed within the front-rear range of a limited installation space (indicated by a dashed line), and a generator (20), a brake module (40), etc. are installed in a line along the front-rear end of the drive shaft (10).

[0059] In particular, in the above embodiment, the acceleration unit (200) is directly connected to the drive shaft (10) so that direct rotational force can be added to the drive shaft (10). However, if the acceleration unit (200) is connected to the end of the drive shaft (10), there is a problem that the front-to-back length of the power generation device becomes unnecessarily long.

[0060] Accordingly, as shown in FIG. 2, the present invention does not directly connect the acceleration unit (200) itself to the drive shaft (10), but rather arranges it in the surplus space around the flywheel (100) and adopts an arrangement configuration that can directly transmit rotational force to the flywheel (100), thereby making more efficient use of the limited installation space and contributing to the miniaturization of the power generation device.

[0061] Before providing a detailed description of the acceleration unit (200), the structure of the flywheel (100) is outlined as follows.

[0062] First, the flywheel (100) can be exemplified as having a configuration that rotates in conjunction with the drive shaft (10) and includes a disk (110).

[0063] The disk (110) has a circular structure in which a shaft coupling hole (111) for a drive shaft (10) to pass through is formed at the center, and a gear tooth (112) is formed on the circumferential surface.

[0064] For such a disk (110), an acceleration member (200) is installed at a position that contacts the tangential direction of the circumferential surface of the disk (110) and reciprocates in a direction perpendicular to the rotational direction of the disk (110) to provide rotational force to the disk (110), thereby enabling this rotational force to be transmitted to the drive shaft (10).

[0065] That is, the acceleration unit (200) in this embodiment is configured to be positioned in the vertical direction of the drive shaft (10) and applies rotational force to the flywheel (100), thereby having an efficient structure that prevents the power generation device from becoming bulky in the forward and backward directions.

[0066] More specifically, the acceleration member (200) can be exemplified as including a translation member (210) and a separation member (220).

[0067] First, the translational member (210) is rotatably installed at one end on the lower part of the disk (110) and has a free end, and performs the function of rotating the disk (110) by engaging with the disk (110) while reciprocating and extending left and right toward the gear teeth (112) of the disk (110).

[0068] The purpose of installing one end of the translational member (210) so as to be rotatable is to realize a structure in which the translational member (210) can be rotated and forcibly separated from the disk (110) by the separation member (220) to be described later.

[0069] When the translation member (210) approaches the disk (110) and moves in a tangential direction while engaging with the gear teeth (112) of the disk (110), a predetermined rotational force is applied to the disk (110), and this rotational force is transmitted to the drive shaft (10) and can be output to the generator (20).

[0070] The translational member (210) that has translated toward the disk (110) in this way does not move backward to its original position, but rotates to the lower part of the disk (110) through the separation member (220) to be described later, and can be intuitively and quickly separated from the disk (110).

[0071] In one embodiment, the translational member (210) may be exemplified as including a first actuator (211) and a first operating bar (212).

[0072] The first actuator (211) can be implemented as a conventional hydraulic or pneumatic cylinder that is installed to rotate in place at a certain distance eccentrically offset from the disk (110) in the left and right directions and operates to extend and retract.

[0073] One end of the first actuator (211) is rotatably connected to a fixed structure not shown via a first hinge member (211a), and the other end is a free end, and a first operating bar (212) is connected to the other end of the first actuator (211) so that it can reciprocate toward the disk (110) in conjunction with the extension and retraction operation of the first actuator (211).

[0074] Accordingly, one end of the first actuator (211) is rotatably connected to the first hinge member (211a), so that the translational member (210) itself is capable of rotating at a certain angle with the first hinge member (211a) as the rotation reference.

[0075] The first operating bar (212) is implemented as a long rod structure extending left and right, with one end connected to the first actuator (211) and the other end forming a free end.

[0076] Accordingly, the first operating bar (212) has a structure that performs a left-right reciprocating linear motion when the first actuator (211) is extended and retracted, and rotates in conjunction with the rotation of the first actuator (211) to move away from the disk (110) or move back to the same line as the disk (110).

[0077] Additionally, on the upper surface of the first operating bar (212), a gear tooth (212a) is formed that meshes with the gear tooth (112) formed on the disk (110), so that when approaching the disk (110) in a tangential direction, it meshes with the gear tooth (112) of the disk (110) and can forcibly rotate the disk (110).

[0078] In a state where the acceleration unit (200) does not form a separate contact with the disk (110), the first operating bar (212) is set to move to the left side of the disk (110) and is spaced apart from the disk (110) so as not to form a separate contact. When the first actuator (211) is operated to extend the flywheel (100) itself to apply rotational force, the first operating bar (212) connected to the first actuator (211) moves to the right and approaches the disk (110) in a tangential direction and engages with the disk (110). In this state, when the first operating bar (212) continuously moves to the right, the linear motion of the first operating bar (212) is converted into rotational motion of the disk (110), thereby providing a predetermined torque to the drive shaft (10).

[0079] Meanwhile, although not shown, a guide slot is formed through the first operating bar (212) along the longitudinal direction, and a spacing member (220) is connected to this guide slot to support the first operating bar (212) so that it can move left and right relative from below, and if necessary, the first operating bar (212) can be pulled downward to forcibly separate the first operating bar (212) from the disk (110).

[0080] At this time, one could consider moving the first operating bar (212) in a straight line to return it to its original position without the action of the separation member (220), but it is obvious that if this were done, reverse torque would be applied to the disk (110), and the return drive of the first operating bar (212) itself would become impossible due to interference from the disk (110).

[0081] Accordingly, the separation member (220) performs the role of separating the translation member (210) engaged with the disk (110) more intuitively and stably from the disk (110) by reciprocating up and down while connected to the other end of the first operating bar (212) of the translation member (210). At this time, the translation member (210) has a structure that supports the first operating bar (212) from below while accommodating the left and right translation of the first operating bar (212), and fulfills the role of pulling it downward and moving it back up.

[0082] To this end, the spacing member (220) can be exemplified as including a second actuator (221) and a guide block (222).

[0083] First, the second actuator (221) is installed at a certain distance eccentrically below the first operating bar (212) and can be implemented as a conventional hydraulic or pneumatic cylinder that extends and retracts vertically.

[0084] The lower end of the second actuator (221) is fixedly installed on a fixed structure not shown, and the uppermost end of the second actuator (221) is provided with a second hinge member (221a), and the guide block (222) is rotatably connected to this second hinge member (221a).

[0085] The guide block (222) is rotatably connected to the second hinge member (221a) of the second actuator (221) and forms a hollow tube structure through which the first operating bar (212) can pass completely left and right to accommodate the reciprocating linear operation of the first operating bar (212) inside.

[0086] In addition, a third hinge member (222a) is integrally provided below the guide block (222) so as to be rotatably connected to the second hinge member (221a), and the guide block (222) itself has a structure that allows angular movement at a certain angle from the second actuator (221).

[0087] Accordingly, as shown in FIG. 9, when the second actuator (221) is fully extended, the first operating bar (212) can be supported in alignment with the bottom point of the disk (110), and as shown in FIG. 10, when the second actuator (221) is fully compressed, the guide block (222) moves downward, and the first operating bar (212) connected thereto is forcibly pulled downward and rotated, and can be separated from the disk (110).

[0088] In this way, as the first operating bar (212) is pulled up and down, it tilts at a certain angle diagonally. Since the guide block (222) that surrounds the outer side of the first operating bar (212) is rotatably connected to the second actuator (221), it has a structure that can flexibly accommodate the angle change of the first operating bar (212).

[0089] In addition, after the first operating bar (212) is separated from the disk (110), the first actuator (211) compresses to return the first operating bar (212) to the left space of the disk (110), and additionally, the second actuator (221) extends to return the first operating bar (212) to the same line as the bottom point of the disk (110), thereby preparing it to move toward the disk (110).

[0090] Hereinafter, the structure of the flywheel (100) will be described in detail with reference to FIGS. 11 to 15.

[0091] The flywheel (100) can be exemplified as including, largely, a disc (110), a pivot weight (120), a support damper (130), a support frame (140), a first actuating gear (150), a second actuating gear (160), an upper guide part (170), and a lower guide part (180).

[0092] First, the discs (110) are provided as a pair of two sets, one in the front and one in the back, spaced apart from each other at a certain distance, with a pivot weight (120), a support damper (130), etc., interposed between them.

[0093] At a periphery point eccentrically offset from the center of the disk (110) by a certain distance outward, a plurality of pivot coupling holes (113) that penetrate the disk (110) in the front-rear direction may be formed at equal intervals along the circumferential direction.

[0094] The pivot weight (120) is configured to perform the function of consuming potential energy stored by the action of gravity into rotational motion, and is a structure curved in an arc shape, having one end rotatably connected through a separate pivot pin (121) to a pivot coupling hole (113) formed at a certain distance eccentric from the center of the disk (110), for example, at the edge of the disk (110), and the other end forming a free end so as to rotate freely on the disk (110).

[0095] At least two of these pivot weights (120) may be arranged at equal intervals along the circumferential direction of the disk (110), and preferably, in this embodiment, four pivot weights (120) are shown applied, but the number is not specifically limited.

[0096] Each pivot weight (120) rotatably coupled to the disk (110) in this way has a structure that rotates outwardly radially toward the outside of the disk (110) or rotates inwardly toward the inside of the disk (110) at a specific angle according to the rotational movement of the disk (110).

[0097] It should be noted that the rotation of the pivot weight (120) described in this explanation means that as the disk (110) rotates, the pivot weight (120) itself rotates in a circumferential direction (angular motion) by following the rotational trajectory of the disk (110). It should also be noted that there may be confusion regarding the meaning that, in another sense, each pivot weight (120) rotates outward or inwardly within the disk (110) itself due to changes in the center of gravity, centrifugal force, inertia, gravity, etc., during the process of rotating in a circumferential direction by the rotation of the disk (110).

[0098] Assuming the case where the disk (110) rotates counterclockwise, the pivot weight (120) that enters in the direction of approximately 9 o'clock to 6 o'clock with gravity applied with the drive shaft (10) as the center of rotation can rotate outward from the disk (110) by centrifugal force and spread radially from the disk (110), and the pivot weight (120) that enters in the direction of approximately 3 o'clock to 12 o'clock rotates inward from the disk (110) and has a state of being housed in the space between a pair of disks (110).

[0099] For example, a pivot weight (120) located at approximately the 11 o'clock position with the drive shaft (10) as the center of rotation begins to be affected by gravity in addition to centrifugal force, and starts an outward rotational motion from the disk (110). Then, when the pivot weight (120) is located at approximately the 9 o'clock position, the accelerated rotational motion is strengthened by the accumulated effect of gravity, causing it to expand radially from the disk (110). Then, it maintains this radially expanded state until it reaches the 7 o'clock position, and when it enters the 12 o'clock position from the 3 o'clock position, the effect of gravity applied decreases, and it eventually reaches the 12 o'clock position, at which point it rotates inward toward the disk (110) and is housed inside the disk (110), and this process is repeated as long as the constant velocity rotation of the disk (110) is maintained.

[0100] A pin coupling hole (122) for pivoting a pivot pin (121) may be formed through the end of each pivot weight (120), and the pivot pin (121) may be connected to the pivot pin (121) while the pin coupling hole (122) of the pivot weight (120) and the pivot coupling hole (113) of the disk (110) are in communication with each other.

[0101] Next, the support damper (130) is installed in the space between a pair of discs (110) and serves to cushion and support a pivot weight (120) that rotates inwardly or outwardly toward the space between the discs (110).

[0102] The support damper (130) may be exemplified by including an inward damper (131) which is fixedly installed around one end of each pivot weight (120) and cushions external impact applied to the disk (110) and reduces operating noise by elastically supporting a part of the pivot weight (120) when the pivot weight (120) rotates inward toward the inside of the disk (110), and an outward damper (132) which is positioned eccentrically at a certain distance from the inward damper (131) and cushions external impact applied to the disk (110) and reduces operating noise by elastically supporting a part of the pivot weight (120) when the pivot weight (120) rotates outward toward the outside of the disk (110).

[0103] That is, a total of two different support dampers (131, 132) are applied to one pivot weight (120) to offset operating shock and noise in various ways.

[0104] The above support damper (130) can be implemented with a conventional coil spring, urethane, rubber, etc.

[0105] The support frame (140) is installed spaced apart from the front of the disk (110) and serves as a structure that supports the upper guide part (170) above the disk (110) and fixes and supports the second operating gear (160) in front of the disk (110).

[0106] In addition, the support frame (140) can serve as a support stand that supports the drive shaft (10) from the installation ground. The support frame (140) can be modified in various ways to support various fixed structures around the disk (110), and the specific structure is not limited.

[0107] The first actuating gear (150) and the second actuating gear (160) can perform the function of engaging with each other when the pivot weight (120) rotates outwardly toward the outside of the disk (110).

[0108] The first actuating gear (150) can be implemented as a movable type that rotates in conjunction with the pivot weight (120), and the second actuating gear (160) can be implemented as a fixed type that is fixedly installed at any position on the support frame (140).

[0109] More specifically, the first actuating gear (150) is integrally connected to the end of the pivot pin (121) and can rotate in conjunction with the pivot weight (120) when it rotates, and the second actuating gear (160) can be implemented as a gear-type structure that is fixed in a position to mesh with the first actuating gear that rotates, preferably at a suitable location on the support frame (140), and meshes with the approaching first actuating gear (150).

[0110] In particular, the second operating gear (160) is fixed in a position that can mesh with the first operating gear (150) of the pivot weight (120) rotating from the 12 o'clock direction to the 9 o'clock direction, so that it can perform the function of meshing with the first operating gear (150) when the pivot weight (120) rotates outward.

[0111] For example, the first operating gear (150), which is linked to the pivot weight (120) that is rotated outward from the disk (110) by rotating the drive shaft (10) in the 9 o'clock direction, passes through the second operating gear (160) in a gear meshing structure, thereby utilizing the rotational force provided by the pivot weight (120) itself due to the lever principle more effectively for the rotation of the drive shaft, and subsequently, one end of the outwardly rotated pivot weight (120) is cushioned and supported by the outward damper (132) of the support damper (130), thereby reducing noise caused by impact.

[0112] In other words, when the pivot (120) opens outward, the first operating gear (150) and the second operating gear (160) engage, and a force is generated by the force pushing like a lever in the direction in which the pivot (120) is to open outward and the force due to the weight of the pivot (120) itself. While the first operating gear (150) and the second operating gear (150) are engaged and moving, continuous rotational force can be transmitted to the drive shaft (10) by the weight of the pivot (120), thereby allowing the potential energy of the pivot (120) to be converted into rotational motion more efficiently.

[0113] In addition, in this situation, since the pivot (120) does not rotate outward radically, some reduction in impact noise of the pivot (120) can also be expected.

[0114] Next, the upper guide part (170) is installed on the upper part of the support frame (140) so as to be spaced apart from the upper part of the disk (110), and performs the function of guiding the pivot weight (120) among the plurality of pivot weights (120) to be rotated outwardly to the upper top point (12 o'clock direction) of the disk (110) while in a state of being rotated inwardly toward the inside of the disk (110).

[0115] The pivot weight (120), which has been rotated and moved in the 12 o'clock direction, is stored in a state where it is rotated inward toward the inside of the disk (110), and as this pivot weight (120) is rotated and moved in the 9 o'clock direction, it is operated to rotate outward by gravity, and at this time, the pivot weight (120) in the 12 o'clock direction is guided on the upper surface of the upper guide part (170) so that outward rotation is initiated.

[0116] The upper guide section (170) is structured such that its upper surface has a gentle curved shape in the form of an arc, and at this time, a guide roller (123) capable of rotating in place on the pivot (120) can be mounted on the outer side of each pivot (120).

[0117] Accordingly, the guide roller (123) can travel on the upper guide section (170) positioned on the outside of the disk (110), and during this process, outward rotation of the pivot weight (120) can be induced, and when the guide roller (123) leaves the upper guide section (170), the pivot weight (120) is separated from the upper guide section (170), and rotational movement in the 9 o'clock direction is naturally achieved by the lever effect and the weight of the pivot weight (120).

[0118] The upper guide section (170) is provided as a pair in the front and rear directions with the pivot weight (120) at the center, and can stably guide the guide roller (123) protruding from the pivot weight (120) in the front and rear directions, provided, however, the upper guide section (170) may be formed only on either the front or rear side.

[0119] Next, the lower guide part (180) is installed spaced apart from the bottom of the disk (110) and performs the function of guiding the pivot weight (120) among the plurality of pivot weights (120) that has been rotated outwardly to the bottom dead center (6 o'clock direction) of the disk (110) to be forcibly rotated inwardly toward the inside of the disk (110).

[0120] That is, the aforementioned upper guide part (170) is configured to forcibly expand the pivot weight (120) stored between the disks (110) outward from the disks (110), whereas the lower guide part (180) is configured to, conversely, forcibly store the pivot weight (120) that has expanded outward from the disks (110) back between the disks (110).

[0121] The lower guide portion (180) may be structured to have a curved surface in an arc shape around the disk (110), and accordingly, when a 6 o'clock pivot weight (120) that is radially extended toward the outside of the disk (110) passes through the lower guide portion (180), it is interfered with by the lower guide portion (180) and is forcibly rotated inward toward the inside of the disk (110) and can be stored in the disk (110).

[0122] At this time, the guide roller (123) provided on the pivot weight (120) is guided to roll in the lower guide part (180), thereby minimizing frictional resistance between the two.

[0123] The lower guide section (180) is provided as a pair in the front and rear directions with the pivot weight (120) at the center, and can stably guide the guide roller (123) protruding from the pivot weight (120) in the front and rear directions, provided, however, the lower guide section (180) may be formed only on one side of the front and rear.

[0124] Meanwhile, a roller storage groove (114) may be formed in a recess at the edge point of the disk (110) to accommodate the guide roller (123) of the pivot weight (120) that is forcibly rotated inward toward the disk (110).

[0125] A flywheel (100) having such a structure may expect an increase in the rotational efficiency of the drive shaft (10) connected to the flywheel (100) through rotational inertia added to the disk (110) itself that supports the outward damper (132) by colliding with the outward damper (132) during the process of each pivot weight (120) rotating outwardly, the inherent weight of each pivot weight (120), the falling energy naturally induced during the outward unfolding process of each pivot weight (120) by this inherent weight, and rotational inertia.

[0126] In particular, it goes without saying that such effects can be fully expected even in embodiments where the aforementioned first operating gear (150) and second operating gear (160) are not specifically applied.

[0127] The embodiments of the present invention described above are merely illustrative, and those skilled in the art will readily understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0128] Therefore, it will be well understood that the present invention is not limited only to the forms mentioned in the above detailed description. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims. Furthermore, the present invention should be understood to include all variations, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.
