Description

Hydro Turbine and Hydro Turbine

The present invention relates to a hydroelectric generator and aberrations for a hydroelectric generator.

Common power generation methods include hydroelectric power generation, fossil fuel-fired power generation, and nuclear power-based nuclear power generation. These power generation methods require large-scale power generation facilities and enormous amounts of energy sources. It causes problems such as constraints, environmental pollution and resource depletion.

Therefore, recently, power generation methods that can utilize energy sources that are environmentally friendly and permanently using natural energy such as solar, tidal, wave, wind, and hydro have been developed and applied.

However, solar power and wind power generation using solar or wind are severely restricted in weather and environment, and tidal power generation using tidal phenomena and wave power generation using wave energy are required to be installed in areas with high tidal difference. It can be obtained has a problem such as following the restrictions of the installation site.

In particular, in areas where large-scale power generation is difficult, such as mountains or rural areas, it is preferable that power supply is performed using a small hydro power generation having a power generation amount of 200 kW or less.

Small-scale power generation is a method of generating electricity by using the flow of nearby small rivers.It is an efficient run of river type in the upstream areas where river slopes are urgent depending on the power generation method, An efficient dam type and a tunnel type suitable for a river with severe bends due to a mixed method of a waterway type and a dam type, etc. There are impact aberration type and reaction type aberration type.

Impact aberrations include Pelton aberrations, Turgo aberrations, and Ossberger aberrations. Recoil aberrations include Kaplan, Tubular, Bulb, and Rim. Propeller aberrations such as Rim) and Francis aberrations.

Compared to other power generation methods, the hydropower generation method, which is relatively less constrained in the installation location and capable of continuously generating electricity, is known to be very useful where small power is required, such as rural areas and mountainous areas, and the Republic of Korea Patent Publication No. 1991-0001971 No. "Small hydroelectric power generation device that produces electric power using river flow" and Korean Utility Model Publication No. 1993-8538, "Small hydroelectric power generation device using hydrological equipment of dam" has been filed.

However, the hydrophobic power generation apparatus described in Korean Patent Publication No. 1991-0001971 is a waterwheel generator of a watermill type that meshes with a beam installed in water, and rotates the generator using a drop of about 2.5 m. Therefore, a topographic location condition having a large drop in the river channel is required, and the topography affects the power generation efficiency.

In addition, the Republic of Korea Utility Model Publication No. 1993-8538 is a structure that requires a free fall because the installation of a reservoir dam, the generator installed in the water gate installed in the reservoir dam to obtain power by using water waterproof from the dam. And it is possible to generate power only when the water is waterproof in the dam, so it is difficult to continuously develop.

Therefore, the conventional hydroelectric power generation device is a structure that is difficult to operate in the topographical terrain, such as farming waterway, horizontal waterway, which is not large, it is not very helpful in the area that really needs to benefit from hydroelectric power generation.

Therefore, the technical problem to be achieved by the present invention is to improve the power generation efficiency of the hydroelectric generator.

Hydroelectric generator according to a feature of the present invention includes a body including a water inlet through which water is introduced and a water outlet through which the water introduced into the water inlet is discharged, and by water introduced onto the body and introduced into the water inlet. Aberrations to rotate to generate rotational force to generate electricity using the rotational force, wherein the aberration includes a plurality of wings whose positions are changed by water introduced into the water inlet, and the plurality of wings are spaced apart And a rotation shaft that rotates by a change in position of the plurality of blades to generate the rotational force, and an angle formed by each of the plurality of blades and an installation surface of the rotation shaft where each of the blades is installed is 106 to 165 degrees.

Each of the plurality of wings may further include a reinforcing bar positioned at at least one of an edge portion and an inner portion of the hydraulic pressure application surface that the water introduced through the water inlet contacts.

The reinforcing bar located at one end of each wing may include an opening.

Each of the plurality of vanes may be an arc-shaped curved plate that protrudes convexly in the rotational direction of the aberration.

Each of the plurality of wings may include at least one chamfer at the edge portion.

The rotation axis may have a circular cross-sectional shape or a polygonal cross-sectional shape.

When the rotating shaft has the circular cross-sectional shape, the rotating shaft may include a plurality of installation grooves into which the plurality of wings are inserted.

When the axis of rotation has a polygonal cross-sectional shape, each of the plurality of vanes may be located one on a flat surface of the axis of rotation.

When the axis of rotation has a polygonal cross-sectional shape, the axis of rotation may have a cross-sectional shape of 5 to 12 polygons.

The upper surface of the body adjacent to the water inlet is preferably an inclined surface inclined along the longitudinal direction of the body.

The distance from the lower surface to the upper surface of the main body is preferably reduced toward the water inlet toward the water outlet.

Hydroelectric aberration according to another feature of the present invention is a plurality of wings that are changed in position by the incoming water, and the plurality of wings are spaced apart to rotate by a change in the position of the plurality of wings to generate a rotational force An angle formed by an installation surface of each of the plurality of blades and the rotary shaft on which the respective blades are installed, including the rotation shaft, is 106 to 165 degrees.

Each of the plurality of wings may further include a reinforcing rod positioned at at least one of an edge portion and an inner portion of the hydraulic pressure-applying surface to which the incoming water is in contact.

The reinforcing bar located at one end of each wing may include an opening.

The rotation axis may have a cross-sectional shape of a pentagonal to octagonal.

According to this feature, since the angle between each wing and the installation surface on which each wing is installed is 106 degrees to 165 degrees, the rotational force and rotational speed of the aberration are increased, and the power generation efficiency of the hydroelectric generator is increased.

In addition, the passage of the water inlet is narrower along the longitudinal direction of the main body, so that the magnitude of the hydraulic pressure applied to the wing located in the main body increases. For this reason, the rotational force of the aberration increases, and the efficiency of the hydroelectric generator is further increased.

In addition, since the size of the contact surface of the blade contacting the water when entering the blade and the water by the chamfer and the opening formed in each blade is reduced, the phenomenon that the flow rate is reduced is prevented.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Next, with reference to the accompanying drawings will be described for the hydroelectric generator and the hydroelectric generator used in the hydroelectric generator according to an embodiment of the present invention.

Referring to Figures 1 to 8 will be described in detail with respect to the hydroelectric generator according to an embodiment of the present invention.

Referring to FIG. 1, the hydroelectric generator 100 according to an exemplary embodiment of the present invention may include a main body 110 installed in a waterway, an aberration 120 installed on the main body 110, and an aberration in the main body 110. A pair of support parts 150 for installing 120, a speed increaser 130 connected to the aberration 120 through the support part 150, a generator 140 connected to the speed increaser 130, and the main body ( The cover 160 is installed on the cover 110 and covers a part of the main body 110 in which the aberration 120 is incorporated.

The main body 110 has a rectangular planar shape, and includes both side surfaces S11, lower surfaces S12, and upper surfaces S13a and S13b.

The inner space of the main body 110 is empty, and the front and rear are open, water is introduced into the open front and then passed through the main body 110 to be output to the rear and discharged to the outside.

Thus, the open front serves as a water inlet 112 through which water is introduced and the open back serves as a water outlet 113 through which water is discharged.

The upper surfaces S13a and S13b of the main body 110 facing the lower surface S12 do not cover the entire upper portion, but are disposed on the upper portion adjacent to the water inlet 111 and the first upper surface S13a and the water outlet ( The second upper surface S13a located in the upper part adjacent to 112 is provided, and the center part between the first and second upper surfaces S13a and S13b is opened.

Therefore, the upper part 111, S13a, S13b does not have the opening part OP1 which exposes a part of lower surface S11, and this opening part OP1 exists in the upper center part of the main body 110, Through the aberration 120 is installed inside the main body 110.

At this time, the first upper surface S13a is an inclined surface having an inclined surface, and the second lower surface 13b has a flat surface.

Therefore, the first upper surface S13a is connected to the inclined portion a1 and the inclined portion a1 inclined toward the lower surface S12 and stands in a direction crossing the lower surface S11 (eg, a vertical direction). A vertical portion a2 is provided.

At this time, the inclined portion (a1) serves as a guide plate for inducing the flow of water, and since the vertical portion (11b) serves as a locking jaw to prevent the separation of the cover 160, the vertical portion (11b) is a locking jaw.

In this example, the inclined portion 11a and the vertical portion 11b are connected seamlessly, so that the inclined portion 11a and the vertical portion 11b are integrally formed.

Thus, by the inclined portion 11a of the inclined upper surface S13a, the height H1 of the main body 110 provided with the inclined portion 11a, that is, the lower surface S11 to the upper surface S13a. The distance decreases toward the water outlet 112, so that the height H1 of the main body 110 decreases from the water inlet 111 to the water outlet 112.

In addition, the height H1 of the portion where the inclined portion 11a is provided has a size smaller than the height H2 of the portion of the main body 110 in which the inclined portion 11a is not provided.

At this time, the thickness H1 of the main body 110 provided with the inclined portion 11a also varies depending on the position, and the thickness H1 decreases toward the water outlet 112.

As a result, the thickness H1 of the discharge passage of the water decreases toward the center portion of the main body 110 rather than the thickness H1 of the end portion of the water inlet 111, so that the inclined portion of the water inlet 111 initially enters the water inlet 111. The pressure of water flowing through (11a) into the center portion increases.

Therefore, the pressure of the water supplied to the aberration 120 installed in the opening OP1 is increased to increase the rotational speed of the aberration 120.

In addition, as the passage of the water inlet 111 through which the water is introduced is narrowed by the first upper surface S13a, the water introduced into the main body 110 may be prevented from rising upwards, thereby preventing each phenomenon of the aberration 120. The contact with water 121 reduces the degree of dispersion of water pressure applied to the wings 121. For this reason, the pushing force of the wing 121 is increased and the rotational force of the aberration 120 is improved.

The aberration 120 has a plurality of vanes 121 and a plurality of vanes 121 are spaced apart by a set distance, each of which has a rotating shaft 122, each of which is located on a pair of supports 150.

In this example, the spacing between two adjacent wings 121 is constant, but is not limited thereto, and in an alternative example, the spacing between two adjacent wings 121 may be different.

The plurality of wings 121 all have the same shape, and each wing 121 may have a plate shape having a rectangular planar shape.

As described above, the plurality of blades 121 are positioned along the rotation shaft 122 and are installed on the outer circumferential surface of the rotation shaft 122 through a fastening device such as welding or bolt.

Each vane 121 is a smooth curved plate that is curved in an arc shape projecting convexly toward the rotation direction A of the aberration 120 and is not formed with irregularities, and one surface of the curved plate, that is, the water inlet A reinforcing rod 121b is provided on a surface (hereinafter, referred to as a “hydraulic pressure application surface”) 121a to which water pressure is applied in direct contact with water introduced through the 111. At this time, each wing 121 is bent toward both sides around the center portion to form a curved plate.

For this reason, each vane 121 is provided with the hydraulic pressure application surface 121a and the reinforcement stand 121b.

In this example, the reinforcing rod 121b completely surrounds the edge portion of the hydraulic pressure applying surface 121a, but is not limited thereto and may be located only at a portion of the edge portion of the hydraulic pressure applying surface 121a.

In addition, although the reinforcing rod 121b is located at a part of the inner portion of the hydraulic pressure applying surface 121a, in an alternative example, the reinforcing rod 121b located at the inner portion of the hydraulic pressure applying surface 121a may be omitted.

Therefore, the edge portion of the hydraulic pressure applying surface 121a is surrounded by the reinforcing rod 121b, and the inner portion of the hydraulic pressure applying surface 121a surrounded by the reinforcing rod 121b is divided into a plurality of regions. Although the number of regions divided by the reinforcing bar 121b is four in this example, the present invention is not limited thereto and may be added or subtracted.

At this time, the installation height of the reinforcing rod 121b provided on the hydraulic pressure applying surface 121a is the same regardless of the position.

Therefore, the hydraulic pressure applying surface 121a and the opposite surface 121c, which is the opposite surface of the hydraulic pressure applying surface 121a by the wing 121 of the curved plate, also have a curved shape protruding toward the rotation direction A of the aberration 120. Since it has, the thickness (that is, thickness in the vertical direction) H3 of the reinforcement stand 121b differs according to a position. That is, the thickness H3 of the reinforcing rod 121b increases from the edge of each wing 121 toward the center.

For this reason, even if the water pressure acts on the hydraulic pressure application surface 121a, the impact applied to the blade 121 is dispersed by the reinforcing rod 121b, and the edge portion and the center portion of the blade 121 momentarily act as a hydraulic pressure. As a result, the problem that the wing 121 is damaged or broken is solved or reduced.

In addition, the water accumulated in the plurality of areas is moved to the center portion of the hydraulic pressure applying surface 121a to further increase the rotational force of the wing 121.

As another example of such a wing 121, as shown in Fig. 6, one end 21a of the wing 121, that is, the other end 21b which is the end of the wing 121 provided on the rotation shaft 122 Reinforcing bar (121b) located at the end located in is omitted, in addition to at least one chamfer 123 to one end 21a and the side of the wing 121, that is, the edge portion of each wing 121 Equipped.

For this reason, the edge part of the hydraulic pressure applying surface 121a is opened through the one end 21a in which the reinforcing rod 121b was omitted instead of being completely surrounded by the reinforcing rod 121b.

In the case of Figure 6, at least one chamfer 123 is located in the center portion of the one end portion 21a located between both side edge portions and both side edges of each wing 121, but the number of such chamfer 123 The formation position can be changed as needed.

When at least one chamfer 123 is provided at the edge portion of the wing 121 as shown in FIG. 6, in an alternative example, at least a portion of the reinforcement part 121b located on the import application surface 121a of the wing 121. Can be omitted.

In addition, as shown in FIG. 7, another example of the wing 121 includes a reinforcing part 121b positioned at an edge of one end 21a of each wing 121 having an opening 124 which is a water passage. have.

By the structure of the wings 121 of FIG. 6 and FIG. 7, the size of the contact surface which the wings 121 and water contact with each other can be obtained by the water is reduced, the flow rate passing through the inside of the main body 110 To reduce its impact. For this reason, the flow rate passing through the main body 110 by the aberration 120 reduces the amount of decrease.

Therefore, when the plurality of hydro power generators 100 are installed in series at a predetermined interval in the waterway, the flow rate of the front hydroelectric generator 100 is prevented from being reduced, and thus, each hydro power generator connected in series due to the decrease of the flow rate. The power generation amount of 100 is prevented from decreasing.

The wing 121 according to the present example is a curved plate, but is not limited thereto, and in an alternative example, each wing 121 may be a flat surface that is not inclined and at least a reinforcing rod 121b provided on the hydraulic pressure applying surface 121a. Some may also be omitted. In this case, the manufacturing of the wing 121 is easy, and the manufacturing time and manufacturing cost of the hydroelectric generator are reduced.

The rotating shaft 122 extends in a bar shape and has a polygonal cross-sectional shape as shown in FIGS. 1 to 7 or a circular cross-sectional shape as shown in FIG. 8.

At this time, as shown in Figure 8, when the rotary shaft 122 has a circular cross-sectional shape, a plurality of installation grooves 22 are formed in the outer peripheral surface portion of the rotary shaft 122 on which each blade 121 is mounted, but is not limited thereto. Do not.

Therefore, when the installation grooves 22 are formed in the rotation shaft 122, each blade 121 is inserted into the installation groove 22, so that the plurality of blades 121 are installed on the rotation shaft 122 by welding or the like. Installation of the wing 121 becomes easy.

The rotation shaft 122 rotates in the same direction (A) as the rotation direction of the aberration 120 as the aberration 120 rotates by moving the position in the corresponding direction (A) by the water flowing into the main body 110. The rotation speed of the rotation shaft 122 is determined according to the rotation speed of the aberration 120.

The main body 110 is inserted in the support part 150 and positioned transversely in the horizontal direction (that is, the direction orthogonal to the longitudinal direction that is the extension direction of the main body 110) on the upper ends of both side surfaces S11 of the main body 110. .

For this reason, a part of the aberration 120 is located inside the main body 110 through the opening part OP1, and at this time, a part of the aberration 120 located inside the main body 110 is approximately about the rotation axis 122. The portion of the aberration 120, which is located at the lower portion of the body 110, is located at the upper portion of the upper portion of the rotation shaft 122.

In the present example, when the rotation shaft 122 has a polygonal cross-sectional shape, a portion where the wing 121 is installed has a polygonal cross-sectional shape, while a portion of the rotation shaft 122 inserted into the support 150 is circular. It has a cross-sectional shape. As a result, the frictional force between the rotation shaft 122 and the support part 150 is reduced to reduce the amount by which the rotational force of the rotation shaft 122 is reduced. However, the present invention is not limited thereto, and a portion of the rotation shaft 122 connected to the support 150 may also have a polygonal cross-sectional shape.

In addition, the thickness of the portion of the rotary shaft 122 inserted into the support 150 is smaller than the thickness (that is, the diameter) of the portion of the rotary shaft 122 on which the wing 121 is installed, so that the coupling with the support 150 can be easily performed. To help.

At this time, the virtual flat surface DS1 formed by the reinforcing rod 121b located on the hydraulic pressure applying surface 121a of the outer circumferential surface portion of the rotary shaft 122 provided with each blade 121 and the other end portion of each blade 121 ( 21b), the angle θ formed by the virtual surface DS2 parallel to the lower surface S11 of the main body 110 is 91 degrees to 165 degrees. Preferably, the angle θ is 106 degrees to 165 degrees.

In an alternative example, when the reinforcing rod 121b is omitted, a virtual plane formed by virtually connecting both sides of the imported application surface of the blade 121 in a virtual straight line becomes a virtual flat surface.

Since the vane 121 is inclined in the rotation direction A with respect to the imaginary surface DS2 which is the installation surface on which the vane 121 is installed at such an angle θ, the vane 121 is caused by the water pressure applied to the vane 121 by the flow of water. While pushing, the aberration 120 can be rotated more easily.

At this time, when the angle θ is 91 degrees or more, the resistance of the water received by the wing 121 is further reduced, so that the rotation operation of the aberration 120 is more smoothly performed. In particular, when the angle is greater than 106 degrees, the wing 121 is The resistance of the water received is further reduced and the rotation operation of the aberration 120 is more smoothly performed. When the angle θ is 165 degrees or less, the degree of inclination of the wing 121 is not excessive and flowed into the main body 110. The water pressure of the water is applied without a great loss, the rotation of the water wheel 120 is made smoothly.

When the rotation shaft 122 has a polygonal cross-sectional shape, the vanes 121 are positioned one on each side 231 of the flat rotation shaft 122. At this time, the number of faces 231 is equal to the number of angles forming a polygon.

In this case, the number of polygons of the polygon of the rotation shaft 122 may vary depending on the size of the angle θ formed between the installation surface DS2 of the wing 121 and the virtual flat surface DS1, for example, five pieces. There may be from twelve to twelve, and thus, the rotation shaft 122 may have a cross-sectional shape of a five to twelve hexagonal shape.

When the rotation shaft 122 is smaller than the pentagon, the number of the wings 121 to be installed becomes five or less, so that the spacing between two adjacent wings 121 is increased. Therefore, the water pressure is not applied to the wing 121 by the reduced water quantity during the dry season, so that the smooth rotation of the aberration 120 may be difficult.

Therefore, when the wing shaft 123 has a cross-sectional shape of five or more shapes, the number of the wings 121 installed on the wing shaft 123 becomes a set number (eg, five) or more, so that the gap between the wings 121 is increased. It decreases below the set interval, the water quantity is reduced during the dry season, even if the water pressure is reduced, the rotation of the aberration 120 is made smoothly. For this reason, the hydroelectric generator 100 according to the present example is smoothly rotated by the aberration 120 even though the quantity of water decreases due to the reduced spacing between the wings 121, so that the generated power does not decrease.

In addition, when the number of the rotating shaft 122 is larger than the octagon 12, the number of the blades 121 installed on the rotating shaft 122 is too large, the manufacturing cost and manufacturing time according to the production of the blade increases, the water resistance increases, so that the aberration 120 Adversely affects the smooth rotation of the.

Therefore, when the rotating shaft 122 is 12 or less in size, the increase in manufacturing time and manufacturing cost due to the number of wings installed on the rotating shaft 122 is prevented and the resistance of water applied to the wings 121 is reduced.

Next, referring to FIGS. 9A and 9B, when the inclined surface is installed at an angle θ greater than 90 degrees with respect to the mounting surface DS2 of the rotating shaft 122 and the mounting surface of the rotating shaft 122. The relationship between the water | wound which acts on each blade | wing 121 and each blade | wing 121 when installing inclined at angle (theta) of 90 degrees or less with respect to DS2 is demonstrated.

In FIG. 9, the number of wings W11-W18 and W21-W28 provided on the rotation shaft 122 is equal to eight, and (a) is a diagram of aberration according to the comparative example, and the mounting surface DS2 and each The size of the angle θ formed by the blades W11-W18 is 90 degrees, and (b) is a diagram of aberration according to an embodiment of the present invention, wherein the mounting surface DS2 and each blade W21-W28 are The magnitude of the angle θ is 130 degrees.

Accordingly, each of the corresponding blades W21-W28 in (b) is inclined 40 degrees further toward the channel 200 compared to the respective blades W11-W18 in FIG. 9A.

For this reason, when the rotation degree of the rotation shaft 122 is the same as each other, each wing (eg, W23) of FIG. 9 (b) is formed before the corresponding wing (eg, W13) of (a) of the waterway 200. The vane W23 is pushed in the water by the water pressure and is pushed in the water flow direction, and the rotating shaft 122 rotates.

Accordingly, the rotation speed of the rotation shaft 122 increases in the case of (b) than in the case of (a) of FIG. 9, and thus, the rotation speed of the rotation shaft 122 also becomes faster than the case of (b).

In addition, the angle of inclination of the surface in contact with the water in the wing (W14) shown in (a) when incident into the water of the two wings (for example, W14, W24) channel 200 located at the same position of the rotary shaft 122 (B) becomes smaller than the inclination angle of the corresponding surface of the said blade W24.

Therefore, the inclination angle of the blade W24 of (b) becomes closer to 90 degrees with respect to the bottom surface of the channel 20 than in the case of (a).

Accordingly, in the case of (a), the water in contact with the surface of the wing (W24) is more generated than the case of (b) in the upward direction along the wing (W24), the pushing force of the wing (W14) Is smaller than the force acting on the blade W24. In addition, the amount of water in contact with the wing W14 of (a) is less than the amount of water in contact with the wing W24 of (b), and the magnitude of the hydraulic pressure acting on the wing W14 is equal to the wing W24 of (b). Much less than the magnitude of the working hydraulic pressure.

Therefore, in the case of (b), the rotational force of the rotation shaft 122 is more easily than in the case of (a), and the rotational force is also large.

In addition, if the position of each wing (e.g., W15, W24) is in the position to receive the greatest hydraulic pressure, the magnitude of the adverse effect of the wing (e.g., W14, W23) immediately adjacent to the front is (b). (A) is much greater than

That is, in the case of (a) of FIG. 9, the size of the path through which the wing W15 can receive water without the interference of the front wing W14 is 'd11', whereas in the case of FIG. 9 (b), The size of the path through which the wing W24 can receive water without interfering with the front wing W23 is 'd21' which is larger than 'd11'.

Therefore, the magnitude of the hydraulic pressure acting on the blade W24 of (b) is greater than the magnitude of the hydraulic pressure acting on the blade W15 of (a). It can be seen that easily made quickly.

Each of the pair of supports 150 has a through hole 151 into which the rotation shaft 122 of the aberration 120 is inserted, and a bearing is built in the through hole 151, and the aberration 121 is provided. The rotating shaft 122 is inserted into the through hole 151 and penetrates the through hole 151 and is connected to the speed increaser 130.

Therefore, the rotation shaft 122 is smoothly rotated within the through hole 151 by the operation of the bearing. At this time, in order to adjust the installation height of the aberration 120 of the present example, the pair of support parts 150 are positioned on the pedestal 152 located on the upper end of the side (S11) of the main body 110.

The speed increaser 130 is provided with a plurality of acceleration gears to increase the rotational speed of the rotary shaft 122 to a predetermined acceleration ratio and transmit it to the generator 140.

The generator 140 is connected to the speed increaser 130 to generate electricity using the rotational force of the rotation shaft 122 transmitted through the speed increaser 130.

Accordingly, the generator 140 converts the rotational force of the aberration 120 into electrical energy to generate and output power of a corresponding magnitude.

The cover 160 covers the opening OP1 of the main body 110 to prevent the accumulation of foreign matter such as fallen leaves that adversely affects the rotation of the aberration 120 inside the main body 110 where the aberration 120 is located. do.

Therefore, the cover 160 is positioned on the upper surfaces S13a and S13b of the main body 110.

At this time, since the cover 160 is located between the inclined portion a1 and the vertical portion a2 of the upper surface S13a, the cover 160 is easily caused by the flow of wind or water by the action of the vertical portion a2. It does not come off.

In this example, the speed increaser 130 and the generator 140 is installed on the side surface (S11) of the main body 110, but is not limited to this may be installed on the water outlet 112 side of the main body 110, The rotational force of the rotation shaft 122 installed on the support 150 may be transmitted to the speed increaser 130 using a pulley connected to the rotation shaft 122 and the speed increaser 130 and a power transmission belt connected to the pulley.

As shown in FIG. 10, when the water flows in through the water inlet 112 of the main body 110 and the water flows through the inside of the main body 110, the hydro power generator 100 having the above structure has a water inlet 112. Water flowing into the main body 110 in contact with the hydraulic pressure applying surface 121a of the blade 121 facing the) while pushing the blade 121 while passing through the water outlet 113 through the main body 110 Will flow outside.

As described above, the position of the wing 121 is moved along the direction A by the water pressure acting on the wing 121 by the pushing action of the water introduced into the main body 110 and integrated with the wing 121. Rotating shaft 122 is also rotated in accordance with the position change of the wing 121, the rotation operation of the aberration 120 is made in the corresponding direction (A).

As such, when the rotation shaft 122 is rotated, the speed increaser 130 in which the support 150 is connected to the rotation shaft 122 through the through hole 151 increases the rotation speed of the rotation shaft 122 by a predetermined acceleration ratio. , To pass to the generator 140.

Thus, the generator 140 generates electricity of a magnitude corresponding to the transmitted rotational force.

Although the present invention having the configuration as described above has been described by a limited embodiment, the present invention is not limited by this and the technical spirit of the present invention and the following by those skilled in the art to which the present invention belongs.
