Description

Environmental protection small-sized hydroelectric generation device

Technical Field

The invention relates to a small hydroelectric power generation device, in particular to an environment-friendly small hydroelectric power generation device which can assist a waterwheel to continuously generate power by pumping and rotating water falling for water quality purification.

Background

Conventional power generation methods include hydroelectric power generation using water power, thermal power generation using fossil fuel, nuclear power generation using nuclear energy, and the like, and these power generation methods require large power generation facilities and a large amount of energy, have limited installation sites, and cause problems such as environmental pollution and resource exhaustion.

Therefore, a power generation method which can utilize natural energy such as solar energy, tidal energy, wave energy, wind power, water power and the like, is environmentally friendly and can permanently use energy is developed at present.

However, solar power generation using solar energy or wind power generation using wind is greatly affected by weather and environment, and tidal power generation using a tidal phenomenon and wave power generation using waves need to be installed in an area with a large difference between low tide and high tide to obtain electric power, so that there is a problem that an installation place is limited.

In mountainous areas or rural areas where large-scale power generation is difficult, small-scale hydroelectric power generation with the power generation amount of less than 200kW is utilized.

As a small-sized hydroelectric power generation method which is less restricted by installation places than these different power generation methods and can generate power continuously, korean registered patent publication No. 10-1782055 proposes a "small-sized hydroelectric power generation device" which can generate power in a waterway, and korean laid-open patent publication No. 10-2017-0116915 "high efficiency waterwheel and small-sized hydroelectric power generation device using the same" and the like, in order to solve the demand for small-sized power in rural areas, mountainous areas, and the like.

However, in such a small hydroelectric power generation apparatus using a waterwheel, if the amount of water flowing into the waterwheel is reduced or exhausted, normal power generation cannot be performed, and thus, normal power generation cannot be continued.

In order to purify fish farms and other fresh water, a construction facility is also required which can utilize the hydraulic power of the falling water as electric power and can generate electric power continuously, in which fresh water is extracted to a sufficient height to allow the fall of the fresh water, and then is dropped to a water truck to perform both the supply and purification.

Detailed Description

The environment-friendly small-sized hydroelectric power generation device according to the preferred embodiment of the present invention will be further described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view showing an environmentally-friendly small-sized hydro-power generation device according to a first embodiment of the present invention.

As shown in FIGS. 1 to 3, the small-sized eco-friendly hydro power generation device (100) of the present invention is provided with a waterwheel (110), first and second seesaw arms (120, 130), a lower pulley (142), an upper pulley (144), a motor (151), a first group of wires (160), a second group of wires (170), a swing motion support (180), and a generator (195).

The waterwheel (110) is a structure rotated by water falling from the terminal end of the downpipe (10), and will be described in detail with reference to fig. 2.

The waterwheel (110) is formed by dividing walls with an upper part opened and a lower part closed unit water storage space (113) separated from each other along the circumferential direction, and the waterwheel (110) can make the discs (112) separated from each other oppositely to contain water and rotate to contain the water falling from the terminal of the downpipe (10).

The center of rotation of the waterwheel (110) is coupled to and extended by a first rotation shaft (111). Reference numeral 118 denotes a rotation support column provided to rotatably support the first rotation shaft (111) on the ground via a support bearing.

The falling water separation inhibiting cover (119) is arranged opposite to the waterwheel (110), and when the waterwheel (110) rotates, the separation amount of the stored water flowing into the unit water storage space (113) from the waterwheel (110) during the falling process is inhibited until the lower end is reached, thereby preventing the loss of the rotating force.

The falling water escape suppressing cover 119 may be a structure that is almost closely attached to the front and side surfaces of the waterwheel 110 without interfering with the rotation thereof and partially covers the same.

The first and second seesaw arms (120, 130) are extended in a direction intersecting the extending direction of the first rotation shaft (111), and coupled to and decoupled from the first rotation shaft (111) in an interlocking manner by first clutches (125) respectively provided on both sides of the first rotation shaft (111) extending in both directions from the rotation center of the waterwheel (110).

Here, as shown in fig. 3, the first clutch (125) includes: a first engaging piece (125a) fixed to the first rotating shaft (111) and concentrically coupled thereto, the first engaging piece having a toothed gear formed on a terminal outer peripheral surface thereof along a circumferential direction; the first rotating shaft (111) is rotatably arranged concentrically, and has a second engaging piece (125b) which is engaged with and rotated or separated from the first engaging piece (125a) when sliding along the longitudinal direction of the first rotating shaft (111) in accordance with the engaging gear of the saw-tooth gear.

Here, the second meshing piece (125b) is in a state of being engaged with the serration gear of the first meshing piece (125a) when the waterwheel rotates along the first rotation shaft (111) in a first rotation direction in which the waterwheel normally rotates, and is released from being engaged with the serration gear and idles when the waterwheel rotates in a direction opposite to the first rotation direction. And a spring (127) is provided between the bearing serving as a fixing piece (126) provided on the first rotating shaft (110) and the second engaging piece (125b), and applies an elastic force in a direction in which the second engaging piece (125b) is brought into close contact with the first engaging piece (125 a).

The first seesaw arm (120) and the second seesaw arm (130) extend in the extending direction crossing the first rotation axis (111), are joined to the second engaging piece (125b), and are lifted and lowered in conjunction with the second engaging piece (125 b). The first seesaw arm (120) and the second seesaw arm (130) are provided to move up and down in mutually opposite directions with respect to the first rotation axis (111).

The first seesaw arm (120) and the second seesaw arm (130) extend to be in a square plate shape, and a plurality of cylindrical weight bodies (128) which can move in the internal accommodating space are arranged in the first seesaw arm and the second seesaw arm to increase the load. The first seesaw arm (120) and the second seesaw arm (130) are configured in such a manner that a part extending opposite to a part extending toward the falling water escape prevention cover (119) with respect to the first rotation axis (111) is extended relatively long.

Reference numeral 138 is a support rod extended from the ground to limit the lowered positions of the first and second seesaw arms (120, 130), and reference numeral 137 is a spring extended upwardly on the support rod (132) formed obliquely to apply elastic buffering when the first and second seesaw arms (120, 130) are brought into downward contact.

The lower pulleys (142) are rotatably provided in two positions on the first seesaw arm (120) and the second seesaw arm (130) away from each other in the direction from the first rotation axis (111) to the support rod (135) and in a direction parallel to the first rotation axis (111) as a rotation center line.

The upper pulleys (144) are arranged on the upper part of a vertical frame (147) extending vertically, and four horizontal frames (148) are respectively and rotatably arranged on two sides of the horizontal frame (148) extending along the direction parallel to the first rotating shaft (111) and taking the direction parallel to the first rotating shaft (111) as a rotating center line.

Here, the number of the upper pulleys (144) is twice as many as the number of the lower pulleys (142), and in order to reduce load sharing in lifting the first seesaw arm (120) and the second seesaw arm (130), as shown in fig. 4, four lower pulleys may be provided, and eight upper pulleys (144) may be provided.

The vertical frame (147) and the horizontal frame (147) correspond to a pillar.

The motor (151) is mounted on a sub-frame (155) extending upward from the ground in front of the waterwheel (110) and can drive to rotate a second rotating shaft (152) extending in a direction parallel to the direction in which the first rotating shaft (111) extends. The rotational force generated by the motor (151) can be transmitted to the second rotary shaft (152) by a power transmission mechanism such as a reduction gear.

The first group of wires (160) has one end coupled to the first seesaw arm (120) and the other end coupled to the first swing arm (181) coupled to one end of the second rotary shaft (152) via the lower pulley (142) and the upper pulley (144).

The first set of conductors (160) is divided into: one end of the first rocker arm (120) is combined, and the other end of the first rocker arm is combined with a front end lead (161) of the single binding machine (161) through a lower side pulley (142) and an upper side pulley (144); a middle end lead (162) connected to a single line between the single binding machine (161) and the turnbuckle (166); a terminal wire (163) connected between the turnbuckle (166) and the first swing arm (181).

Here, a single binding machine (161) binds a plurality of leading wires (161) passing through an upper pulley (144) to one middle wire (162), and a turnbuckle (166) adjusts the tension of the wires.

One end of the second group of wires (170) is coupled to the second seesaw arm (130), and the other end is coupled to the second swing arm (182) coupled to the other end of the second rotation shaft (152) via the lower pulley (142) and the upper pulley (144).

The second set of conductors also uses the same manner as the first set of conductors described above, including: one end of the second seesaw arm (130) is combined with the front end lead (171) of the single binding machine (161) through the lower pulley (142) and the upper pulley (144); a middle lead (172) connected as a single line between the single binding machine (161) and the turnbuckle (166); a terminal wire (173) connected between the turnbuckle (166) and the second swing arm (182).

The swing motion support part (180) performs a first swing motion in which the first seesaw arm (120) ascends and descends within a set angle range, and rotates the waterwheel (110) in order to perform a second swing motion opposite to the first swing motion in a mode in which the second seesaw arm (130) descends when the first seesaw arm (120) ascends, and applies a rotational force of the second rotational shaft (152) to the first and second groups of wires (160) (170).

The swing motion support section (180) is composed of a first rotating arm (152) and a second rotating arm (182).

The first rotating arm (181) extends from one end of the second rotating shaft (181) in a direction perpendicular to the direction in which the second rotating shaft (181) extends, and is bound to the terminal wire (163) of the first group of wires (160) by a rotating pin (181a) rotatably provided at the terminal.

The second rotating arm (182) extends from the other end of the second rotating shaft (181) to a direction crossing at right angles with the extending direction of the second rotating shaft (181), and extends in a direction opposite to the extending direction of the first rotating arm (181) through a terminal wire (173) bound to the second group of wires (170) by a rotating pin (182a) rotatably provided at the terminal.

According to these structures, when the second rotation axis (152) rotates in the first direction, the first rotation arm (181) and the second rotation arm (182) rotate 180 degrees different from the rotation direction, and further, the first seesaw arm (120) and the second seesaw arm (130) are lifted by repeating the pulling and releasing with the second rotation axis (152) of the first group of wires (160) and the second group of wires (170) as a reference.

In this process, when the first seesaw arm (120) ascends, the engagement of the first clutch (125) is released without hindering the rotation of the waterwheel (110), and the second seesaw arm (130) descended is such that the first clutch (125) is engaged and coupled to apply a rotational force in the rotational direction of the waterwheel (110). Similarly, when the second rocker arm (130) is raised, the engagement of the first clutch (125) is released and no rotational force is applied to the waterwheel (110), and when the first rocker arm (120) is lowered, the first clutch (125) is engaged and rotational force is applied to the waterwheel (110).

The above operation is repeated to continuously rotate the waterwheel (110).

The generator (195) receives the rotational force of the waterwheel (110) and generates electric power.

In the illustrated example, the generator (195) is provided to generate electric power by the rotational force of a power generation gear (194) rotatably provided in mesh with a circumferential gear (192) concentrically integrated with the waterwheel (110).

When the water supply amount to the waterwheel (110) is suddenly reduced and the power generation amount of the generator (195) is kept constant, the motor (151) is operated to generate the rotation power of the waterwheel (110) through the lifting of the first rocker arm (120) and the second rocker arm (130) in the manner described above, thereby achieving the purpose of continuously generating power.

In addition, a swing motion supporting portion different from the illustrated example may be employed, which is described in detail below with reference to fig. 4.

According to fig. 4, the rocking motion support portion (280) is provided with a first reel (281) and a second reel (282), a second clutch (225), a separation interfering piece (167), and a separation guide (250). Reference numeral 158 is a shaft support frame that supports the second rotation shaft (152) through a bearing.

The first reel 281 is set to rotate together with or separate from the second rotation shaft 152 by a second clutch 225 provided at one end of the second rotation shaft 152, and is formed in a cylindrical shape, and the terminal lead 163 of the first group lead 160 is wound or unwound.

The second reel (282) is also configured to rotate in conjunction with or separately from the second rotation shaft (152) by a second clutch (225) provided at the other end of the second rotation shaft (152), and to wind or unwind the terminal lead (173) of the second group of leads (170), and when the terminal lead (163) of the first group of leads (160) is unwound from the first reel (281), the terminal lead (173) of the second group of leads (170) is wound.

The second clutch (225) is fixedly coupled concentrically to the second rotation shaft (152) by a first engagement piece (225a) which forms a zigzag gear in the circumferential direction in the same manner as the first clutch (125), and is rotatably provided concentrically to the second rotation shaft (152) and a second engagement piece (225b) which forms an engagement gear corresponding to the zigzag gear by rotating or separating the first engagement piece (225a) so as to be engaged with the second engagement piece (225b) for sliding movement in the longitudinal direction of the second rotation shaft (152) is coupled to the first spool (281) and the second spool (282).

The separation interference piece (167) is provided on the first group lead wire (160) and the second group lead wire (170), and interference that separates the first reel (281) and the second reel (282) by the first engagement piece (225a) of the second clutch (225) is applied by interference with the separation guide (250) to be described later.

In the illustrated example, the separation interference piece (167) is tapered and formed integrally with the turnbuckle (166), and the outer diameter thereof is gradually increased from the front end exposed in the direction of the first reel (281) and the second reel (282) to the rear end.

In contrast, to separate from the turnbuckle 166, other components may be fixedly coupled between the turnbuckle 166 and the terminal wires 163, 1736 in the tapered configuration described above.

Reference numeral 164 is a protection tube equipped to protect a portion of the terminal lead (163) extending from the turnbuckle (166).

The separation guide (250) is provided so as to interfere with the separation interfering piece (167) in a direction in which the first spool (281) and the second spool (282) are separated from the first engagement piece (225a) of the second clutch (225) when the separation interfering piece (167) reaches the release position of the first spool (281) and the second spool (282).

The separation guide 250 is supported by the sub-frame 155 at a position interfering with the traveling path of the separation interfering piece 167. The interference part of the separation interference piece (167) contacting the separation guide (250) is formed by inclining the protruding distance with the motor (151) as going toward the first reel (281) and the second reel (282) to be gradually longer, so that the separation interference piece (167) slides and moves in the direction away from the motor (151) when the separation interference piece (167) enters.

On the other hand, the fixed ends (163a) (173a) fixed to the first reel (281) and the second reel (282) of the first group of conductive wires (160) and the second group of conductive wires (170) are in a state where the first reel (281) and the second reel (282) are engaged with the first engaging piece (225a) of the first clutch (225) on the curved outer peripheral surfaces (281a) (282a) of the first reel (281) and the second reel (282), before the separation interference piece (167) is interfered by the separation guide (250), the first and second sets of conductive wires (160, 170) are fixed at positions farther from the central portions of the first and second reels (281, 282) in the width direction away from the first engaging piece (225a) of the second clutch (225) with reference to a reference extension line (R) extending toward the first and second reels (281, 282).

A movement limiting stopper 260 is provided between the first and

second reels

281 and 282 and the separation guide 250, and when the terminal

conductive line

163 and 173 is unwound from the first and

second reels

281 and 282 by a predetermined length or starts to be wound, the movement of the position where the terminal

conductive line

163 and 173 is wound or unwound is limited by the fixed ends of the first and

second reels

281 and 282, and the terminal

conductive line

163 and 173 is interfered at the position between the reference extension line R and the fixed ends 163a and 173.

Here, the outer diameters of the first reel (281) and the second reel (282) depend on the length of the wire that is wound and unwound to switch on the first reel (281) and the second reel (282) of the terminal wire (163) (173) to a length that is not wound once on the first and second reels (281) (282).

According to these configurations, before the separation interfering piece (167) is interfered by the separation guide (250), the second engaging piece (225b) engages with the first engaging piece (225a) of the second clutch (225) and the terminal lead (163) (173) is wound on one of the first reel (281) and the second reel (282), and when the separation interfering piece (167) enters the separation guide (250) to start interference, the separation interfering piece (167) moves in a direction away from the first engaging piece (225a) along the inclined surface of the separation guide (250), and during this, the position where the terminal lead is wound on the contact of the first reel (281) and the second reel (282) is changed and the first and second reels (281) (282) move to a position separated from the second engaging piece (225b), and further the rotational directions of the first reel (281) and the second reel (282) and the second rotational shaft (152) are rotated in opposite directions, so that the terminal wires (163) (173) are unwound from the first reel (281) and the second reel (282).

And in the process that the terminal wires (163) (173) are completely released from the first reel (281) and the second reel (282), when the fixed ends (163a) (173a) of the first reel (281) and the second reel (282) fixed to the first and second sets of wires (160) (170) are rotated to proper positions, the portions of the terminal wires (163) (173) between the movement limiting stoppers (260) and the fixed ends (163a) (173a) are maintained in a tightened state in an inclined state, a moving force of the first reel (281) and the second reel (282) toward the first engaging piece (225a) (225b) is provided, and thus the second clutch (225) is restored to the engaged state again.

These processes run in reverse on a first reel (281) and a second reel (282).

On the other hand, in order to make the process of rebinding after the first reel (281) and the second reel (282) are separated from the first engaging piece (225) from the first engaging piece (225a) more smooth, as shown in the figure, a coupling interference piece (286) and a coupling guide (287) may be further provided.

The connection interference piece 286 is provided on a first outer side surface which is opposite to the second engagement piece 225b with reference to the first reel 281 and the second reel 282, and is formed to protrude in a direction parallel to the longitudinal direction of the second rotation shaft 152 on the outer side surfaces of the first reel 281 and the second reel 282 so that the first reel 281 and the second reel 282 are moved in a direction to be connected to the first engagement piece 225a by an interference force when the first reel 281 and the second reel 282 are rotated to a ready winding position after being released from rotation in a state where the first engagement piece 225a is separated from the first reel 281 and the second reel 282.

Here, the protruding position of the coupling interference piece (286) may be, for example, a structure in which the first reel (281) and the second reel (282) are formed to gradually protrude along the circular closed orbit from 310 degrees when the angle of separation from the first engagement piece (225a) is 0 degree on the circular closed orbit having the same radius and the protruding position of the coupling interference piece (286) on the outer side surface starts to protrude at a position rotated to 310 degrees on the circular closed orbit.

The connecting guide member 287 is provided to interfere with the connecting interference piece 286 so that the first reel 281 and the second reel 282 are moved in a direction of the first engaging piece 225a connected to the second clutch 225 when the connecting interference piece 286 reaches the aforementioned ready-to-wind position of the first reel 281 and the second reel 282.

The coupling interference piece 286 may be fixedly mounted on a bearing provided on the shaft support frame 158, or may be mounted to be supported by the shaft support frame 158 to perform the interference function.

On the other hand, in fig. 5, the turnbuckle (166) is a structure in which a separation interference piece (167) is provided at the terminal end, and when the first reel (281) and the second reel (282) reach a position separated from the second engagement piece (225a) of the second clutch (225), the contact with the turnbuckle (166) is lowered. At this time, the separation interference piece (167) is provided corresponding to the interference position of the turnbuckle (166), and is set to be restored by the spring (167) when the descending and interference is released.

In contrast, the fixed ends (163a) (173a) of the first reel (281) and the second reel (282) fixed to the first group of conductive wires (160) and the second group of conductive wires (170) among the first reel (281) and the second reel (282) may be fixed at the center corresponding to the extending position of the reference extending line (R) extending to the first reel (281) and the second reel (282) of the conductive wires (160) (170), and at this time, as shown in fig. 6, the separation interfering piece (386) may be provided on the first and second reels (281) (282), and the separation guide (387) may be fixedly provided at the ready-to-release position facing on the rotation orbit of the separation interfering piece (386).

That is, when the separation interfering piece (386) is provided on the second outer side surface formed by the second engagement piece (225b) of the second clutch (225) with the first reel (281) and the second reel (282) as a reference and the first reel (281) and the second reel (282) are rotated to the ready-to-release position after being wound in a state of being connected to the first engagement piece (225a) of the second clutch (225), the first reel (281) and the second reel (282) are moved in a direction of being separated from the first engagement piece (225a) of the second clutch (225) along the second rotation shaft (152) by an interfering force.

The separating guide (387) is provided on an auxiliary stay (159) extending from the ground to an upper height facing the separating interference piece (386). A separation guide (387) is provided on the auxiliary column (159) so as to interfere with the separation interfering piece (386) such that the first reel (281) and the second reel (282) move in a direction of separating from the first engagement piece (225a) of the second clutch (225) when the separation interfering piece (386) reaches a ready-to-release position of the first reel (281) and the second reel (282).

Here, the separating operation of the separating interference piece (386) and the separating guide (387) is performed in a manner corresponding to the coupling operation of the coupling interference piece (286) and the coupling guide (287).

According to these structures, the first group of conductive wires (160) and the second group of conductive wires (170) can be formed in a straight winding and unwinding, not in a diagonal winding, as shown in fig. 4, thereby reducing frictional resistance during the coupling and unwinding along the second rotation axis (152).
