Description

Eco-friendly small hydropower generation device

[0001] The present invention relates to an eco-friendly small hydropower generation device, and more specifically, to an eco-friendly small hydropower generation device constructed to assist in the continuous power generation of a water turbine that is rotated by water that is pumped and falls for water purification.

[0002] Common power generation methods include hydroelectric power using water, thermal power using fossil fuels, and nuclear power using nuclear energy. These methods require large-scale power generation facilities and massive amounts of energy sources, causing problems such as site constraints, environmental pollution, and resource depletion.

[0003] Therefore, recently, power generation methods utilizing natural energies such as solar, tidal, wave, wind, and hydroelectric power are being developed and applied to enable the permanent use of energy sources in an eco-friendly manner.

[0004] However, solar and wind power generation, which utilize solar or wind energy, are subject to significant constraints due to weather and environmental conditions. Additionally, tidal power generation, which utilizes tidal phenomena, and wave power generation, which utilizes wave energy, impose limitations on installation locations as they must be installed in areas with large tidal ranges to generate the necessary electricity.

[0005] Meanwhile, in areas where large-scale power generation is difficult, such as mountainous or rural regions, small-scale hydropower generation with a power generation capacity of about 200 kW or less is also used.

[0006] As a small hydropower generation method capable of continuous power production with relatively fewer restrictions on installation location compared to other power generation methods, the "small hydropower generation device" installed in a waterway to perform power generation in Korean Registered Patent Publication No. 10-1782055 and the "high-efficiency water turbine and small hydropower generation device using the same" in Korean Published Patent Publication No. 10-2017-0116915 have been proposed.

[0007] However, small-scale hydroelectric power generation systems using such water turbines have a disadvantage in that it is difficult to maintain continuous power generation at all times, as normal power generation becomes difficult when the amount of water flowing into the turbine decreases or becomes depleted.

[0008] Meanwhile, in the case of facilities constructed to perform oxygen supply and purification by pumping freshwater to a sufficient height for purification of fish farms or other freshwater and then dropping it through a water wheel, there is a need for a structure that can utilize the hydropower of the falling water to generate electricity while also enabling continuous power generation.

[0009] The present invention was devised to solve the above-mentioned requirements, and aims to provide an eco-friendly small-scale hydroelectric power generation device capable of supporting continuous power generation even with fluctuations in the amount of water supplied to the turbine.

[0010] To achieve the above objective, the eco-friendly small hydroelectric power generation device according to the present invention comprises: a water turbine that is rotated by falling water; first and second seesaw arms installed on both sides of a first rotation axis extending in both directions from the rotation center of the water turbine, extending in a direction intersecting the extension direction of the first rotation axis; a main clutch unit configured such that when each of the first and second seesaw arms is rotated upward with respect to a first rotation center line parallel to the extension direction of the first rotation axis, the first and second seesaw arms are separated from the first rotation axis, and when they are lowered, the first and second seesaw arms are coupled to the first rotation axis and rotated in intermittent linkage with the first rotation axis; a motor that drives a second rotation axis extending along a direction parallel to the extension direction of the first rotation axis; a first wire with one end coupled to the first seesaw arm; and a second wire with one end coupled to the second seesaw arm.

[0012] In addition, the swing motion support member comprises a first rotation winder that is coupled to and separated from the second rotation axis through a first clutch with respect to the second rotation axis at one end of the second rotation axis and is connected to the first wire; A second rotary winding member is provided at the other end of the second rotary shaft, which is coupled to and separated from the second rotary shaft through a second clutch and connected to the second wire; the first clutch is provided with a first clutch arm that interferes with the first seesaw arm when the first seesaw arm reaches a target position for upward movement, thereby separating the first rotary winding member from the second rotary shaft; the second clutch is provided with a second clutch arm that interferes with the second seesaw arm when the second seesaw arm reaches a target position for upward movement, thereby separating the second rotary winding member from the second rotary shaft; and the first clutch arm and the second clutch arm are coupled in series through a third wire to perform mutual seesaw motion.

[0013] Additionally, the first and second rotary winders are installed to be elastically sliding along the longitudinal direction of the second rotation axis toward the center of the second rotation axis through a pressure spring mounted at the end, and the first and second clutch arms are provided with a main part extending parallel to the extension direction of the second rotation axis and an interference part extending downward from one end of the main part, the other end of the main part is supported through a first seating spring mounted on the upper end of the first auxiliary support, and one end of the main part is connected through the third wire, and the first and second rotary winders are provided with a second friction linkage part that rotates in close contact with a first friction linkage part formed on the second rotation axis by the pressure spring, and the interference part is configured to enter between the first friction linkage part and the second friction linkage part to separate the linkage state, and the extension length of the third wire is of the first clutch arm If the interference portion is positioned between the first friction linkage portion of the first rotary winding and the second friction linkage portion, the interference portion of the second clutch arm is constructed to have a length that separates it from the first friction linkage portion of the second rotary winding and the second friction linkage portion.

[0022] Hereinafter, an eco-friendly small hydropower generation device according to a preferred embodiment of the present invention will be described in more detail with reference to the attached drawings.

[0023] FIG. 1 is a perspective view showing an eco-friendly small hydropower generation device according to one embodiment of the present invention.

[0024] Referring to FIG. 1, the eco-friendly small hydroelectric power generation device (100) according to the present invention comprises a water turbine (110), first and second small arms (120) (130), a lower pulley (152), an upper pulley (154), a motor (160), a first wire (171), a second wire (172), a swing motion support unit (180), and a generator (195).

[0025] The water wheel (110) is formed in a structure that can be rotated by water falling from the end of the water guide tube (10), and is explained with reference to FIG. 2.

[0026] The water wheel (110) is structured such that it is formed by a partition wall (114) that is spaced apart along the circumferential direction, with a unit water storage space (113) having an open top and a closed bottom, which can accommodate water falling from the end of the water guide tube (10) to induce rotation.

[0027] A first rotation axis (111) is coupled to and extended at the rotation center of the water wheel (110). Reference numeral 118 is a rotational support column arranged to rotatably support the first rotation axis (111) on the ground through a support bearing.

[0028] A water leakage prevention cover (119) is installed opposite the water wheel (110) so as to prevent loss of rotational power by preventing the amount of water that flows into the unit water storage space (113) of the water wheel (110) and is stored during the water wheel (110) from escaping from the water wheel (110) during the falling process until it reaches the bottom.

[0029] The water leakage prevention cover (119) can be positioned to cover the front and side portions of the water wheel (110) in a nearly close contact state without causing rotational interference.

[0030] The first and second diaphragm arms (120) (130) are installed on both sides of the first rotation axis (111) which extends in both directions from the rotation center of the water wheel (110) in a direction intersecting the extension direction of the first rotation axis (111), and are explained together with reference to FIG. 3.

[0031] The first and second seesaw arms (120) (130) are configured to rotate intermittently in conjunction with the first rotation axis (111) by means of the main clutch part (140). The first and second seesaw arms (120) (130) are constructed to perform seesaw motion in mutually opposite directions relative to the first rotation axis (111).

[0032] The first and second seesaw arms (120) (130) perform a seesaw motion by means of a main clutch (140) and a swing motion support part (180), and the first seesaw arm (120) performs a first swing motion in which it moves up and down within a set angle range, and the second seesaw arm (120) is configured to perform a second swing motion opposite to the first swing motion in a pattern in which the second seesaw arm (130) moves down when the first seesaw arm (120) rises.

[0033] The first and second siphonal arms (120) (130) are connected to the second interlocking gear (142) described later and swing up and down around the interlocking rotation axis (145), and are configured to partially rotate the interlocking rotation axis (145) in forward and reverse directions in conjunction with the swing movement.

[0034] The first and second pediatric arms (120) (130) are extended in the form of square panels, and multiple cylindrical weights (128) are embedded inside to increase the load.

[0035] The first and second clutch arms (120) (130) have a first part (120a) (130a) that extends in the direction toward the water leakage prevention cover (119) relative to the interlocking rotation axis (145) and functions as a weight, and a second part (120b) (130b) that extends in the opposite direction toward the water leakage prevention cover (119) and acts as an interference bar that interferes with the first and second clutch arms (185) (186) described later.

[0036] In the illustrated example, the second part (120b) (130b) is extended at an angle with respect to the extension direction of the first part (120a) (130a) at the end of the first part (120a) (130a).

[0037] These first and second diaphragm arms (120) (130) can be configured such that, when the first part (120a) (130a) descends, the load of the first part (120a) (130a) is significantly larger than that of the second part (120b) (130b) based on the interlocking rotation shaft (145) so that sufficient rotational force can be applied to the water wheel (110) by the falling force caused by the load during the descending of the first part (120a) (130a).

[0038] Reference numeral 135 is a lower support rod extending from the ground to limit the lowering position of the first and second sibling arms (120) (130). Reference numeral 136 is a lowering buffer spring mounted to extend upward on the upper surface of the lower support rod (135) so as to correspond to the lowering point reached by the first and second sibling arms (120) (130), and applies elastic force to mitigate impact when the first and second sibling arms (120) (130) make lowering contact.

[0039] Additionally, reference numeral 137 is a rising buffer spring installed at a rising point corresponding to the rising target position reached by the first and second seesaw arms (120) (130) rising on the bottom surface of an upper stopper (138) installed to extend downward on the main support (101), and applies elastic force when the first and second seesaw arms (120) (130) make upward contact to mitigate the impact.

[0040] Here, the upper support rod (138) and the main support (101) correspond to a second auxiliary support that supports the mounting of the rising cushioning spring (137).

[0041] The main clutch (140) is constructed such that when the first and second pivot arms (120) (130) are each rotated upward with respect to a first rotation center line parallel to the extension direction of the first rotation shaft (111), the first and second pivot arms (120) (130) are separated from the first rotation shaft (111), and when they are lowered, the first and second pivot arms (120) (130) are coupled to the first rotation shaft (111), and this is explained together with reference to FIG. 3.

[0042] The main clutch (140) is equipped with a first linkage gear (141) and a second linkage gear (142).

[0043] The first interlocking gear (141) is installed concentrically with the first rotation shaft (111) on each side of the first rotation shaft (111).

[0044] On the outer surface of the first interlocking gear (141), a gear portion in which a gear is formed along the outer surface and a sector gear having an omitted portion so that the gear is omitted and separated are applied.

[0045] The second interlocking gear (142) is installed concentrically on an interlocking rotation shaft (145) that is rotatably installed with respect to a first rotation center line parallel to the extension direction of the first rotation shaft (111), and is separated from the first interlocking gear (141) when the first seesaw arm (120) and the second seesaw arm (130) rotate upward, and meshes with the first interlocking gear (141) when the first seesaw arm (120) and the second seesaw arm (130) rotate downward.

[0046] Here, the interlocking rotation shaft (145) is rotatably installed through a support bearing installed on a rotational support column (118) above the support bearing supporting the first rotation shaft (111).

[0047] On the outer surface of the second interlocking gear (142), a gear portion in which a gear is formed along the outer surface and a sector gear having an omitted portion so that the gear is omitted and separated are applied.

[0048] The second linkage gear (142) is formed in a semicircular shape having a surface-treated portion, and the first and second linkage arms (120) (130) are integrally joined to the upper part of the surface-treated portion.

[0049] Unlike the illustrated example, the first and second sibling arms (120) (130) can be coupled to the second interlocking gear (142) via an interlocking rotation shaft (145). That is, the interlocking rotation shaft (145) of the second interlocking gear (142) can be constructed to be connected to the first and second sibling arms (120) (130), respectively.

[0050] This main clutch (140) can mitigate shock during the coupling and disassembly process.

[0051] The lower pulley (152) is located lower than the upper pulley (154) and is installed via the main support (101) so as to be rotatable in conjunction with the movement of the first wire (171) and the second wire (172) on the respective movement paths of the first wire (171) and the second wire (172), and is described with reference to FIGS. 5 to 7.

[0052] A plurality of lower pulleys (152) are rotatably installed at positions spaced apart from the first rotation axis (111) of each of the first and second sibling arms (120) (130) along the direction toward the lower support rod (135), with the rotation center line parallel to the first rotation axis (111).

[0053] The upper pulley (154) is installed via the main support (101) so as to be rotatable in conjunction with the movement of the first wire (171) and the second wire (172) on the respective movement paths of the first wire (171) and the second wire (172).

[0054] Multiple upper pulleys (154) are installed so as to be rotatable with the rotation center line running parallel to the first rotation axis (111).

[0055] The lower pulley (152) and the upper pulley (154) are installed to be supported through a support bracket (103) that extends downward from the main support (101).

[0056] In the illustrated example, multiple lower pulleys (152) and upper pulleys (154) are applied, and the winding pattern is wound as shown in FIG. 7, passing from the upper pulley (154) to the lower pulley (152) and then back to the upper pulley (154) and lower pulley (152).

[0057] The lower pulley (152) and the upper pulley (154) are applied to distribute the power required for the rise of the first and second diaphragms (120) (130).

[0058] One end of the first wire (171) is connected to the first siphon arm (120) and the other end is connected to the first rotary winding (183) described later, and is installed to pass through the lower and upper pulleys (152) (154).

[0059] One end of the second wire (172) is connected to the second siphon arm (130) and the other end is connected to the second rotary winding (184) described later, and is installed to pass through the lower and upper pulleys (152) (154).

[0060] Reference numeral 157 is a rotating drum that supports the first and second wires (171) (172) passing through the upper pulley (154) to switch the movement path for forward and backward movement and to smoothly support sliding movement, and is mounted on the main support (101).

[0061] Here, the main support (101) has a structure having a vertical frame (101a) that extends vertically from the ground and a horizontal frame (101b) that extends horizontally parallel to the extension direction of the first rotation axis (111) at the top of the vertical frame (101a).

[0062] The motor (160) rotates the second rotational shaft (162) which is extended along a direction parallel to the extension direction of the first rotational shaft (111). Here, the rotational force generated from the motor (160) can be configured to be transmitted to the second rotational shaft (162) through a power transmission element such as a reduction gear.

[0063] The motor (160) is installed on a drive support (105) that extends upward from the ground. In the illustrated drawing, the drive support (105) supporting the second rotation shaft (162) described later and the drive support (105) supporting the motor (160) are illustrated as having a structure separated from each other, but it is obvious that they can be constructed as a single unit.

[0064] The swing motion support unit (180) is constructed to apply rotational force of the second rotation axis (162) through the other ends of the first and second wires (171) (172) during the section in which the first and second seesaw arms (120) (130) are raised so that the water wheel (110) is rotated by the second seesaw arm (130) performing a second swing motion opposite to the first swing motion in a pattern in which the first seesaw arm (120) rises and the second seesaw arm (130) falls, and is described with reference to FIGS. 3 and FIGS. 4.

[0065] The swing motion support unit (180) is equipped with first and second clutches (181)(182) and first and second rotation winders (183)(184).

[0066] The first rotary winder (183) is connected to and separated from the second rotary shaft (162) via the first clutch (181) at one end of the second rotary shaft (162) and is connected to the other end of the first wire (171). The first rotary winder (183) is formed in a circular reel shape so that the first wire (171) can be wound or unwound by forward and reverse rotation. The first rotary winder (183) is installed to allow sliding movement and relative rotation on the second rotary shaft (162).

[0067] The second rotary winder (184) is connected to and separated from the second rotary shaft (162) via the second clutch (182) with respect to the second rotary shaft (162) at the other end of the second rotary shaft (162) and is connected to the other end of the second wire (172). The second rotary winder (184) is formed in a circular reel shape so that the second wire (172) can be wound or unwound by forward and reverse rotation. The second rotary winder (184) is installed to allow sliding movement and relative rotation on the second rotary shaft (162).

[0068] That is, the first and second rotation winders (183) (184) are installed so as to be elastically sliding along the longitudinal direction of the second rotation axis (162) toward the center of the second rotation axis (162) through a pressure spring (181a) (182a) mounted at the end.

[0069] In this case, the first and second rotary windings (183) (184) can be mounted in a structure that allows them to be inserted through an insertion hole so as to be reciprocally and rotatable on the second rotary shaft (162).

[0070] The first clutch (181) is equipped with a first clutch arm (185) that interferes with the second part (120b) of the first seesaw arm (120) when the first seesaw arm (120) reaches the target position, thereby separating the first rotation winder (183) from the second rotation shaft (162).

[0071] The second clutch (182) is equipped with a second clutch arm (186) that interferes with the second part (130b) of the second seesaw arm (130) when the second seesaw arm (130) reaches the target position, thereby separating the second rotation winding (184) from the second rotation shaft (162).

[0072] Here, the first clutch arm (185) and the second clutch arm (186) are connected in series through the third wire (188) to perform a seesaw motion with each other.

[0073] The first and second clutch arms (185) (186) are structured to have a main part (185a) (186a) extended along a direction intersecting the extension direction of the second rotation axis (162), an interference part (185b) (186b) extended downward from one end of the main part (185a) (186a), and a pressing guide part (185c) (186c) extended upward from the middle of the main part (185a) (186a).

[0074] Here, the pressing guide portion (185c) (186c) is a portion that interferes with the lowering of the second portion (120b) (130b), causing the interference portion (185b) (186b) to descend downward.

[0075] Additionally, the other end of the main part (185a) (186a) is supported by a first set spring (107) mounted on the top of the first auxiliary support (106), and one end of the main part (185a) is connected by a third wire (188).

[0076] The first and second rotational windings (183) (184) are integrally provided with a second frictional interlocking part (162b) that is rotated in close contact with a first frictional interlocking part (162a) formed on the second rotational shaft (162) by means of a pressure spring (181a) (182a), and an interference part (185b) is inserted between the first frictional interlocking part (162a) and the second frictional interlocking part (162b) to separate the interlocking state.

[0077] The extension length of the third wire (188) is such that when the interference portion (185b) of the first clutch arm (185) is inserted between the first friction linkage portion (162a) and the second friction linkage portion (162b) of the first rotary winder (183), the interference portion (186b) of the second clutch arm (186) is separated from the first friction linkage portion (162a) and the second friction linkage portion (162b) of the second rotary winder (184).

[0078] One end of the third wire (188) is connected to the interference portion (185b) of the first clutch arm (185), and the other end is connected to the interference portion (186b) of the second clutch arm (186). The third wire (188) is allowed to move by supporting the intermediate portion connecting the one end and the other end through a relay ring (188a) that is spaced apart from each other at the top of the alternating interference support post (108).

[0079] The generator (195) generates power by receiving the rotational force of the water turbine (110).

[0080] The generator (195) is installed to generate power by the rotational force of a generator gear that is installed to rotate by meshing with a circular gear formed integrally with the water turbine (110).

[0081] According to this structure, as shown in FIGS. 1 and 3, when the second rotation shaft (162) is rotated in a driving direction capable of winding the first and second wires (171) (172), the first clutch (181) is maintained in a connected state so that the first rotation winder (183) is in a close connection with the second rotation shaft (162), as indicated by the solid line, and when the second clutch (182) is maintained in a separated state from the second rotation shaft (162), as indicated by the dotted line, the first rotation winder (183) rotates in conjunction with the second rotation shaft (162). In this process, the first seesaw arm (120) rises due to the pulling and winding of the first wire (171). Likewise, the second seesaw arm (130) descends in the opposite direction to the first seesaw arm (120). During the process of the second siphon arm (130) descending, the first linkage gear (141) and the second linkage gear (142) of the main clutch (140) mesh with each other to transmit the falling force generated during the descent process to the water wheel (110), thereby rotating the water wheel (110).

[0082] Additionally, as the first seesaw arm (120) rises to the position indicated by the dotted line, the first clutch arm (185) interferes with the lowering of the first clutch arm (185b), and as the interference portion (185b) lowers, when the first seesaw arm (120) reaches the target position for rising, the first clutch (181) is separated from the second rotation shaft (162). Afterwards, self-lowering proceeds due to its own weight, and during this process, the first linkage gear (141) and the second linkage gear (142) of the main clutch (140) mesh with each other to transmit the falling force generated during the lowering process to the water wheel (110), thereby rotating the water wheel (110). As this process is repeated and the first and second seesaw arms (120) (130) alternately rise and fall, the first and second seesaw arms (120) (130) that remain engaged with the second rotation shaft (162) of the motor (160) rise, and the one separated from the second rotation shaft (162) falls. During this process, until the first seesaw arm (120) rises and reaches the target position, the first clutch (181) remains engaged, and the main clutch (140) is released from engagement so as not to hinder the rotation of the water wheel (110). Additionally, as the second seesaw arm (130) falls, the engagement with the second clutch (182) is released, and the main clutch (140) remains engaged to apply rotational force in the direction of rotation of the water wheel (110). By repeating this operation, the water wheel (110) can be continuously rotated.

[0083] Therefore, when the amount of water supplied to the water turbine (110) is rapidly reduced and the amount of power generated by the intended generator (195) is to be maintained at a constant level, the motor (160) is operated to generate rotational power of the water turbine (110) by raising and lowering the first and second sill arms (120) (130) in the manner described above, thereby allowing power generation to continue.

[0084] Meanwhile, as shown in FIG. 8, if a water wheel (110) described above is placed on one side of a fish farm or other reservoir (10) where fresh water is stored, and piping (20) is installed to supply fresh water from the other side to the water wheel (110) by operating a pump (P) (30), a circulating water flow is automatically generated, and the purification capacity of the fresh water can also be improved.

[0085] The eco-friendly small hydroelectric power generation device described above offers the advantage of supporting continuous power generation even with fluctuations in the amount of water supplied to the turbine.
