Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hydraulic power generating apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic power generating apparatus and a water turbine for a hydraulic power generating apparatus.

Typical power generation methods include hydroelectric power generation, thermal power generation using fossil fuels, and nuclear power generation using nuclear power. These power generation methods require large-scale power generation facilities and enormous amounts of energy sources. Problems such as pharmaceuticals and environmental pollution and resource exhaustion.

Therefore, in recent years, power generation methods that utilize natural energy such as solar heat, tidal power, wave power, wind power, and hydro power to utilize an energy source in an environmentally friendly and permanent manner have been developed and applied.

However, solar and wind power generation using solar or wind is severely restricted by weather and environment. Tidal power generation using tidal phenomenon and wave power generation using wave energy must be installed in areas where there is a great deal of difference between tides. There is a problem that the installation place is restricted.

Particularly, in areas where large-scale power generation is difficult, such as mountainous areas and rural areas, it is preferable that power supply is carried out using small hydroelectric power generating power of 200 kW or less.

Small hydroelectric power generation is a method of generating electricity by using the water in a nearby small river stream. It is an efficient run-river type in the upstream region where the river slope is urgent according to the generation method and a region where the river- There is an efficient dam type (storage type) and a tunnel type suitable for rivers with severe bends due to the combination of a waterway type and a damping type. There are impact type aberrations and recoil type aberrations.

Pelton aberration, Turgo aberration, Ossberger aberration and the like can be classified into Kaplan, Tubular, Bulb, Rim, Rim), and Francis aberration.

It is known that the small-scale hydroelectric power generation method which is less restrictive than the other power generation methods and is capable of continuously generating electric power is very important where small-sized electric power is required, such as rural and mountain areas, and disclosed in Korean Patent Publication No. 1991-0001971 , "Small Hydro Power Generation Device for Generating Electric Power Using Stream Water", and "Small Hydro Power Generation Device Using Dam Hydrologic Device", etc., were also filed.

However, the small hydroelectric power generation device disclosed in Korean Patent Laid-Open Publication No. 1991-0001971 is a water turbine type water turbine generator which is rotated in conjunction with a beam installed in the water, and the generator is rotated by using a drop of about 2.5 m. Therefore, the geographical location condition with a large drop in the river channel is needed, and it is affected by the power generation efficiency by the topography.

In addition, the Korean Utility Model Utility Model No. 1993-8538 is a structure in which a low water dam is installed and a generator is installed in the water gate installed in the low water dam to obtain power using water that is waterproofed in the dam. And it is a structure that can generate electricity only when the water is waterproofed in the dam, so that it is difficult to continuously develop it.

Therefore, the conventional small-scale hydroelectric power generation apparatus is a structure that is difficult to operate in a terrain or a horizontal channel where the water level is not so low as an agricultural waterway, and thus it is not very helpful in a region where it is necessary to actually benefit from the small hydroelectric power generation.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art.

A hydroelectric power generating apparatus according to one aspect of the present invention includes a main 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 a plurality of blades whose positions are changed by the water introduced into the water inlet, and a plurality of blades which are positioned so as to be spaced apart from each other, And an angle formed between each of the plurality of blades and a mounting surface of the rotary shaft on which the blades are installed is 106 to 165 degrees.

Each of the plurality of vanes may further include a reinforcing bar located at least one of an edge portion and an inner portion of the water pressure applying surface to which the water introduced through the water inlet is in contact.

The ribs at one end of each wing may include openings.

Each of the plurality of blades is a curved surface plate of an arc shape protruding convexly in the rotating direction of the aberration.

Each of the plurality of blades may include at least one chamfered portion at an edge portion thereof.

The rotating shaft 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 mounting grooves into which the plurality of blades are inserted.

When the rotary shaft has a polygonal sectional shape, each of the plurality of blades may be positioned on the flat surface of the rotary shaft.

When the rotation axis has a polygonal cross-sectional shape, the rotation axis may have a cross-sectional shape of pentagonal to hexagonal.

The upper surface of the main body adjacent to the water inlet may be an inclined surface inclined along the longitudinal direction of the main body.

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

According to another aspect of the present invention, there is provided an aquarium for hydroelectric power generation, comprising: a plurality of blades whose positions are changed by water to be introduced; and a plurality of blades which are positioned so as to be spaced apart from each other, Wherein an angle formed between each of the plurality of blades and a mounting surface of the rotating shaft on which the blades are provided is 106 to 165 degrees.

Each of the plurality of vanes may further include a reinforcing bar located at least one of an edge portion and an inner portion of a water pressure applying surface to which the incoming water abuts.

The ribs at one end of each wing may include openings.

Each of the plurality of blades is a curved surface plate of an arc shape protruding convexly in the rotating direction of the aberration.

Each of the plurality of blades may include at least one chamfered portion at an edge portion thereof.

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

According to this feature, since the angle between each blade and the mounting surface on which the blades are provided is 106 degrees to 165 degrees, the turning power and the rotating speed of the aberration increase, and the power generation efficiency of the hydroelectric power generator is increased.

Further, the passage of the water inlet is narrower along the longitudinal direction of the main body, so that the magnitude of the water pressure applied to the wing located in the main body increases. As a result, the rotational force of the aberration increases and the efficiency of the hydrodynamic power generator further increases.

In addition, since the chamfer portion and the opening formed in each wing reduce the size of the contact surface of the wing that comes into contact with the water when entering each wing and water, the phenomenon that the flow velocity is reduced is prevented.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Hereinafter, a hydraulic auger for a hydro-electric power generator used in a hydro-electric generator and a hydro-electric generator according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 to 8, a hydraulic power generating apparatus according to an embodiment of the present invention will be described in detail.

Referring to FIG. 1, a hydroelectric power generating apparatus 100 according to an embodiment of the present invention includes a main body 110 installed in a water channel, a water turbine 120 installed on the main body 110, A pair of supporters 150 for supporting the turbine 120 and a generator 130 connected to the turbine 120 via the supporter 150 and a generator 140 connected to the gearbox 130, And a lid 160 installed on the main body 110 to cover a part of the main body 110 having the aberration 120 therein.

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

The inner space of the main body 110 is empty, and the front and rear surfaces are opened to allow water to flow into the opened front surface, pass through the inside of the main body 110,

Accordingly, the open front serves as a water inlet 112 through which water is introduced, and the open rear surface functions as a water outlet 113 through which water is discharged.

The upper surfaces S13a and S13b of the main body 110 opposed to the lower surface S12 do not cover the entire upper surface but are located on the first upper surface S13a and the water outlet 112 and is open at the middle between the first and second upper surfaces S13a, S13b.

Therefore, the upper surface 111, S13a, S13b is not located at the center of the upper portion of the main body 110, and an opening OP1 exposing a part of the lower surface S11 exists. 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 inclined toward the lower surface S12 and the inclined portion a1 abutted against the lower surface S11 in a direction (for example, vertical direction) And a vertical part (a2).

At this time, the inclined portion a1 functions as an induction plate for guiding the flow of water, and the vertical portion 11b functions as a latching jaw for preventing the lid 160 from separating from the vertical portion 11b.

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.

The inclined portion 11a of the inclined upper surface S13a allows the height H1 of the main body 110 provided with the inclined portion 11a to be increased from the lower surface S11 to the upper surface S13a The distance decreases toward the water outlet 112 and the height H1 of the body 110 decreases from the water inlet 111 to the water outlet 112. [

The height H1 of the portion where the slope portion 11a is provided is smaller than the height H2 of the portion of the main body 110 where the slope 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 discharge port 112. [

The thickness H1 of the water discharge passage decreases toward the center portion of the main body 110 from the thickness H1 of the end portion of the water inlet 111 so as to be smaller than the pressure of the water initially entering the water inlet 111, The pressure of the water flowing into the middle portion through the passage 11a increases.

Accordingly, the pressure of the water supplied to the aberration 120 installed in the opening OP1 increases to increase the rotational speed of the aberration 120. [

In addition, since the passage of the water inlet 111 through which the water flows is narrowed by the first upper surface S13a, the water introduced into the main body 110 is prevented from rising upward, The amount of the water pressure applied to the wing 121 decreases. As a result, the pushing force of the wing 121 increases, and the turning force of the aberration 120 is improved.

The aberration 120 includes a plurality of vanes 121 and a plurality of vanes 121 spaced apart from each other by a predetermined distance and includes a rotation shaft 122 having both ends located on a pair of supports 150.

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

Each of the plurality of blades 121 has the same shape, and each of the blades 121 may have a plate shape having a rectangular planar shape.

As described above, the plurality of blades 121 are located apart from each other along the rotating shaft 122 and are installed on the outer peripheral surface of the rotating shaft 122 through a fastening device such as welding or bolt.

Each wing 121 is a smooth curved plate curved in a convexly protruding shape toward the direction of rotation A of the aberration 120 and having no unevenness. One surface of the curved plate, that is, (Hereinafter, this surface is referred to as a 'water pressure applying surface') 121a directly contacting with the water introduced through the water inlet 111 and applying a water pressure thereto. At this time, each wing 121 is curved to both sides around the center portion to form a curved plate.

As a result, each blade 121 has a water pressure applying surface 121a and a reinforcing bar 121b.

In this example, the reinforcing bar 121b completely surrounds the edge portion of the water pressure applying surface 121a, but is not limited to this, and may be located only in a part of the edge portion of the water pressure applying surface 121a.

Further, the reinforcing bar 121b is located in a part of the inside portion of the water pressure applying face 121a, but in an alternative example, the reinforcing bar 121b located in the inner portion of the water pressure applying face 121a may be omitted.

The inner portion of the water pressure applying surface 121a surrounded by the reinforcing table 121b is divided into a plurality of regions. The number of regions divided by the reinforcing bar 121b is four in this example, but it is not limited to this and can be added or subtracted.

At this time, the installation height of the reinforcing bars 121b provided on the water pressure applying surface 121a is the same irrespective of the position.

Therefore, the water pressure applying surface 121a and the opposite surface 121c opposite to the water pressure applying surface 121a by the blade 121 of the curved surface plate also have a curved surface shape protruding toward the rotational direction A of the aberration 120 The thickness (i.e., the thickness in the longitudinal direction) H3 of the reinforcing bar 121b differs depending on the position. That is, the thickness H3 of the reinforcing bar 121b increases from the edge of each wing 121 to the center.

The water pressure applied to the water pressure applying surface 121a causes the impact applied to the wing 121 to be dispersed by the supporting table 121b and the water pressure applied momentarily at the edge portion and the middle portion of the wing 121 The problem of damaging or breaking the wing 121 is solved or reduced.

In addition, the water in the plurality of regions moves to the center portion of the water pressure applying surface 121a, thereby further increasing the rotational force of the wing 121.

Another example of such a wing 121 is an end portion 21a of the wing 121, that is, the opposite side of the other end 21b, which is an end of the wing 121 provided on the rotary shaft 122, And at least one chamfered portion 12 is further provided on one end 21a of the wing 121 and on the side of the wing 121, that is, at the edge of each wing 121. In addition, Respectively.

Therefore, the edge portion of the water pressure applying surface 121a is completely surrounded by the reinforcing bar 121b, but is opened through the one end 21a where the reinforcing bar 121b is omitted.

6, at least one chamfered portion 12 is located at the center portion of one end 21a located between both side edges and both side edges of each wing 121, but the number of chamfered portions 12 And the forming position can be changed as needed.

When at least one chamfered portion 12 is provided at the edge portion of the wing 121 as shown in Fig. 6, at least part of the reinforcing portion 121b located on the importing face 121a of the wing 121 in the alternative example Can be omitted.

7, another example of the wing 121 includes a reinforced portion 121b located at an edge portion of one end 21a of each wing 121 and has an open opening 124 as a water passing portion have.

6 and 7, the size of the contact surface where the wing 121 and the wing 121, which are in contact with water, is reduced, and the flow rate of the water flowing through the inside of the main body 110 . ≪ / RTI > As a result, the flow rate passing through the main body 110 by the aberration 120 reduces the amount of reduction.

As a result, when the plurality of hydroelectric power generation apparatuses 100 are installed in series in the water channel at a constant interval, the flow rate due to the hydroelectric power generation apparatus 100 at the previous stage is prevented from being reduced, Thereby preventing the power generation amount of the battery 100 from being reduced.

The wing 121 according to this embodiment is a curved plate, but the present invention is not limited thereto. In an alternative example, each wing 121 may be a flat surface that is not inclined and at least one of the reinforcing bars 121b provided on the water pressure applying surface 121a Some of which may also be omitted. In this case, the production of the wings 121 is easy, and the production time and manufacturing cost of the hydroelectric power generation apparatus are reduced.

The rotating shaft 122 is elongated 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, when the rotary shaft 122 has a circular cross-sectional shape, a plurality of installation grooves 22 are formed on the outer circumferential surface portion of the rotary shaft 122 on which the blades 121 are mounted. However, Do not.

Therefore, when the mounting groove 22 is formed in the rotary shaft 122, the blades 121 are inserted into the mounting groove 22, and a plurality of blades 121 are installed on the rotary shaft 122 through welding or the like The wings 121 can be easily installed.

The rotating shaft 122 is rotated in the same direction A as the rotating direction of the aberration 120 as the aberration 120 moves in the corresponding direction A by the water flowing into the main body 110, And the rotation speed of the rotation shaft 122 is determined in accordance with the rotation speed of the aberration 120.

Is inserted into the support portion 150 and is positioned transversely to the upper end of both sides S11 of the main body 110 in a transverse direction (i.e., a direction perpendicular to the longitudinal direction of the main body 110) .

A part of the aberration 120 is located inside the main body 110 through the opening OP1 and the part of the aberration 120 located inside the main body 110 is approximately And the portion of the aberration 120 located outside the main body 110 is a portion positioned substantially at the upper portion with the rotation axis 122 as a center.

In the present embodiment, when the rotary shaft 122 has a polygonal cross-sectional shape, the portion where the blade 121 is provided has a polygonal cross-sectional shape, while the portion of the rotary shaft 122 inserted into the support portion 150 has a circular Sectional shape. This reduces the frictional force between the rotating shaft 122 and the supporting portion 150, thereby reducing the amount by which the rotating force of the rotating shaft 122 is reduced. However, the present invention is not limited to this, and the portion of the rotation shaft 122 connected to the support portion 150 may also have a polygonal cross-sectional shape.

The thickness of the portion of the rotation shaft 122 inserted into the support portion 150 is smaller than the thickness (i.e., diameter) of the portion of the rotation shaft 122 on which the wing 121 is installed, so that coupling with the support portion 150 is facilitated .

At this time, a virtual flat surface DS1 formed by the reinforcing strip 121b located on the water pressure applying surface 121a among the outer circumferential surface portions of the rotating shaft 122 on which the wings 121 are installed and the other end portion The angle? Formed by the lower surface S11 of the main body 110 and the imaginary plane DS2 parallel to the main surface 21a is 21 degrees to 165 degrees. Preferably, the angle [theta] is from 106 degrees to 165 degrees.

In an alternative example, when the reinforcing bar 121b is omitted, a hypothetical plane formed by virtually connecting the both sides of the importing face of the wing 121 in a straight line is a virtual flat face.

The blade 121 is inclined in the rotational direction A with respect to the imaginary plane DS2 which is the installation surface provided with the blade 121 at the angle? So that the aberration 120 can be more easily rotated.

In this case, when the angle? Is 91 degrees or more, the resistance of the water received by the wing 121 is further reduced, and the rotation of the aberration 120 is performed more smoothly. The degree of inclination of the wing 121 is not excessively increased so that the flow of the water 120 to the main body 110 can be suppressed. The water pressure of the water is applied without a large loss and the aberration 120 is smoothly rotated.

When the rotary shaft 122 has a polygonal cross-sectional shape, the blades 121 are positioned on each side 231 of the flat rotary shaft 122 one by one. At this time, the number of the planes 231 is the same as the number of angles forming the polygon.

The angular shape of the polygonal shape of the rotary shaft 122 may vary depending on the angle θ formed by the mounting surface DS2 of the blade 121 and the imaginary flat surface DS1, To 12, whereby the rotating shaft 122 may have a pentagonal to a twelve-sided cross-sectional shape.

When the rotational axis 122 is smaller than the pentagonal shape, the number of the wings 121 provided is less than 5, and the distance between the adjacent two wings 121 is increased. As a result, water pressure is not applied to the vanes 121 due to the reduced water quantity during the dew, and smooth rotation of the aberration 120 may be difficult.

Therefore, when the wing axis 123 has a cross-sectional shape of a pentagonal shape or more, the number of the wings 121 provided on the wing axis 123 becomes equal to or larger than the set number (for example, 5) The amount of water decreases at the time of dusk and the water pressure decreases, and the aberration 120 is smoothly rotated. Thus, the hydraulic power generation apparatus 100 according to the present embodiment smoothly performs the rotation of the aberration 120, and the generated power is not reduced, even if the water quantity is reduced by the interval between the reduced blades 121.

If the number of the blades 121 provided on the rotary shaft 122 is too large, the manufacturing cost and manufacturing time of blades increase, and the resistance of water increases to increase the aberration 120 ) Is adversely affected.

Accordingly, when the rotary shaft 122 is 12 or less, the manufacturing time and manufacturing cost are prevented from increasing due to the number of blades installed on the rotary shaft 122, and the resistance of water applied to the blades 121 is reduced.

Next, referring to Figs. 9A and 9B, when the inclination is set at an angle &thetas; greater than 90 DEG with respect to the mounting surface DS2 of the rotating shaft 122, The relationship between water acting on each blade 121 and each blade 121 when it is inclined at an angle? Of 90 degrees or less with respect to the blade DS2 will be described.

9, the number of vanes W11-W18 and W21-W28 provided on the rotary shaft 122 are equally eight, wherein (a) is a diagram of aberration according to a comparative example, The mounting surface DS2 and each of the wings W21 to W28 are arranged at an angle of 90 degrees with respect to the mounting surface DS2 and the angle θ formed by the wings W11 to W18 is 90 degrees, The angle? Is 130 degrees.

Therefore, the corresponding wings W21-W28 of (b) are inclined to the water channel 200 by 40 degrees, as compared to the wings W11-W18 of FIG. 9 (a).

9B, the wings (e.g., W23) of Fig. 9B are positioned at a position before the corresponding wings (e.g., W13) of Fig. 9A And the wing W23 is pushed by the water pressure in the direction of the water flow, so that the rotating shaft 122 is rotated.

Therefore, in the case of FIG. 9 (b), the number of revolutions of the rotating shaft 122 increases and the rotating speed of the rotating shaft 122 also becomes faster than that of FIG. 9 (a).

When two wings (for example, W14 and W24) located at the same position on the rotary shaft 122 are incident into the water of the water channel 200, the inclination angle of the surface in contact with water in the wing W14 shown in Becomes smaller than the inclination angle of the corresponding surface of the blade (W24) of (b).

Therefore, the angle of inclination of the wing W24 of (b) is closer to 90 degrees with respect to the bottom surface of the channel 20 than that of (a).

Accordingly, in the case of (a), the amount of the phenomenon in which the water in contact with the surface of the vane W24 rises in the upward direction along the vane W24 is greater than that in the case of (b) Becomes smaller than the force acting on the vane W24. The amount of water in contact with the wing W14 of Fig. 10A is smaller than the amount of water contacting the wing W24 of Fig. 10B, and the magnitude of the water pressure acting on the wing W14 is smaller than that of the wing W24 of Fig. Much less than the magnitude of the hydraulic pressure acting.

Therefore, in the case of (b), the rotational motion of the rotating shaft 122 is also easier and the rotational force is larger than that of (a).

In addition, when the position of each of the vanes (e.g., W15 and W24) is located at a position where the force of water pressure is the largest, the magnitude of the adverse effect caused by the vanes (e.g., W14 and W23) (A) is much larger.

That is, in the case of FIG. 9A, the size of the path through which the wing W15 can receive water without disturbance of the front wing W14 is 'd11', whereas in the case of FIG. 9B, The size of the path through which the wing W24 can receive the water without disturbance of the front wing W23 is d21 larger than d11.

Therefore, when the magnitude of the water pressure acting on the wing W24 of (b) is larger than the magnitude of the water pressure acting on the wing W15 of (a) Can be easily and quickly performed.

Each of the pair of supporters 150 has a through hole 151 into which the rotation axis 122 of the aberration 120 is inserted and a bearing is built in the through hole 151. The aberration 121, The rotation shaft 122 of the shaft 130 is inserted into the through hole 151 and is connected to the booster 130 through the through hole 151.

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

The speed reducer 130 includes a plurality of accelerating gears, and increases the rotational speed of the rotating shaft 122 at a predetermined acceleration ratio, and transfers the increased rotational speed to the generator 140.

The generator 140 is connected to the booster 130 and generates electricity using the rotational force of the rotary shaft 122 transmitted through the booster 130.

Accordingly, the generator 140 converts the rotational force of the aberration 120 into electric energy, and generates and outputs electric power of a corresponding magnitude.

The lid 160 covers the opening OP1 of the main body 110 and prevents foreign objects such as leaves from being accumulated inside the main body 110 in which the aberration 120 is located, do.

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

Since the lid 160 is positioned between the inclined portion a1 and the vertical portion a2 of the upper surface S13a, the lid 160 is easily moved by the flow of wind or water due to the action of the vertical portion a2. It does not peel off.

In this case, the booster 130 and the generator 140 are installed on the side surface S11 of the main body 110, but are not limited thereto and may be installed on the side of the water discharge port 112 of the main body 110, The rotational force of the rotating shaft 122 installed on the support unit 150 can be transmitted to the booster 130 by using a rotating shaft 122 and a pulley connected to the booster 130 and a power transmission belt connected to the pulley.

10, when the water flows into the water inlet 112 of the main body 110 and water flows through the main body 110, the water inlets 112 The water flowing into the main body 110 through the water discharge port 113 while pushing the wing 121 while the water introduced into the main body 110 contacts the water pressure application surface 121a of the wing 121 facing the wing 121, And flows outward.

As a result of the water pressure applied to the wing 121 by the pushing action of the water introduced into the main body 110, the position of the wing 121 is moved along the corresponding direction A, The rotation shaft 122 connected to the wiper 121 also rotates in accordance with the change of the position of the wing 121 so that the rotation of the aberration 120 is performed in the corresponding direction A.

When the rotary shaft 122 is rotated, the booster 130 connected to the rotary shaft 122 through the through hole 151 increases the rotation speed of the rotary shaft 122 by a predetermined acceleration ratio , And transmits it to the generator (140).

Accordingly, the generator 140 generates electricity of a size corresponding to the transmitted rotational force.
