1 is a plan view for explaining a hydro power generation system according to an embodiment of the present invention, Figure 2 is a side cross-sectional view for explaining a hydro power generation system.

Referring to FIGS. 1 and 2, the hydro power generation system S includes a power generator 1, a lower groove 2, and a gate 3.

Hydroelectric power generation system (S) is installed in the river (R), etc., where water moves from the upstream to the downstream direction, the potential energy is converted into kinetic energy as the water moves in the downstream direction (not shown) Rotating and to obtain electricity by using the electromagnetic induction phenomenon as the turbine for power generation (not shown) to be described later.

Here, the upstream means the upward direction based on FIG. 1, and the downstream means the lower direction based on FIG. 1.

1 and 2, the generator 1 is installed on one side of the order wall CW. The order wall CW protrudes in an upward direction (upper direction based on FIG. 2) from the bottom surface FS, which will be described later, in order to prevent penetration of water upstream in the steel R and the like, so as to prevent infiltration. It may be formed extending in the other direction so as not to contact the other one of both sidewalls forming a width (left-right with reference to Figure 1), such as).

That is, in the hydro power generation system S, the generator 1 is installed at one side of the order wall CW, whereby the movement path of the water moving from the upstream to the downstream is narrowed by the order wall CW, so that the flow rate (water movement speed) This raises more effectively the turbine for power generation (not shown) which will be provided later in the power generator 1 can be rotated more effectively.

As described above, the power generator 1 may be formed on one side of the order wall CW. More specifically, the power generator 1 may include any one of both sidewalls forming the width of the steel R and the steel ( It may be formed between the order walls CW extending from one of the two side walls forming the width of R) (direction toward either one of the side walls forming the width of the steel R).

1 and 2, the generator 1 includes a housing 11 having a predetermined inclination, a water channel 12 provided in the housing 11, and a turbine for power generation provided on the water channel 12. (Not shown).

The housing 11 may be connected to any one of both sidewalls forming the width of the steel R, or at least one of the order wall CW and the bottom surface FS, and the like in a conventional manner. .

The water channel 12 is a path for moving upstream water downstream, and a turbine for power generation (not shown) is provided on the water path to rotate by the kinetic energy of the water. As the turbine for power generation (not shown) rotates, it causes an electromagnetic induction phenomenon to produce electric power. Since this will be apparent to those skilled in the art, more detailed description will be omitted.

The predetermined inclination (the inclination of the housing 11 having the water channel 12 therein) is preferably formed adjacent to the vertical direction so that the kinetic energy of water adjacent to the turbine for power generation (not shown) is maximized. Herein, the vertical direction refers to the upper-lower direction with reference to FIG. 2.

1 and 2, the lower groove 2 is provided on the bottom surface FS, and is recessed by a predetermined depth from the lower end of the housing 11.

Here, the bottom surface FS may refer to a ground (ground floor) such as a river R in which water moves from upstream to downstream.

As described above, in order to maximize the kinetic energy of water adjacent to the turbine for power generation (not shown), the rear lower end of the housing 11 having the water channel 12 therein is disposed adjacent to the bottom surface FS. As moving foreign matter (sand, stone, tree branches, etc.) accumulates between the housing 11 and the bottom surface FS, foreign matters are accumulated in the water channel 12 inside the housing 11, and the turbine for generation Can impede driving).

Here, the rear is based on the moving direction of the water, the water is introduced from the front of the channel 12 and discharged to the rear. That is, the front of the housing 11 may mean the left side (upper side based on FIG. 1) based on FIG. 2, and the rear side may mean the right side (lower side based on FIG. 1) based on FIG. 2.

As such, the housing 11 and the bottom surface FS are included by including the lower groove 2 recessed downwardly by a predetermined depth from the bottom surface FS adjacent to the lower end of the housing 11 (for example, the rear lower end). Since the space between the axles is expanded, foreign matters (sediments) and the like can be accumulated to prevent foreign matters and the like from flowing into the channel 12. In other words, by maintaining the slope of the channel 12 to maximize the kinetic energy of the water adjacent to the turbine for power generation (not shown), it is possible to suppress the accumulation of deposits and the like.

1 and 2, the gate 3 opens and closes the rear of the lower groove 2. As described above, the rear means a direction in which water and foreign substances (sediments), etc. introduced into the lower groove 2 are discharged based on the moving direction of the water. That is, when the gate 3 forms a rear sidewall of the lower groove 2 to close the rear of the lower groove 2, foreign matters and the like may be accommodated in the lower groove 2.

In this way, by closing the lower groove (2) through the gate (3), within the limit that the lower groove (2) receives the foreign matter to reduce the movement path of the water to move downstream only through the water channel (12) Increasing the flow rate of water in 12) has the advantage of maximizing the kinetic energy of the water near the generator turbine (not shown).

The gate 3 is preferably formed of a material in which water permeation is suppressed.

At this time, when there is a risk that foreign matter may flow into the channel 12 as the foreign matter accumulates in the lower groove 2, the rear of the lower groove 2 may be opened by operating the gate 3.

For example, the gate 3 is provided at the lower end of the housing 11 and connected to a rotation shaft 31 that rotates about the width direction (direction parallel to the width direction of the steel R) of the housing 11 about the central axis. The rear of the lower groove 2 can be opened and closed. The rotary shaft 31 may be connected to the drive motor 32 to be driven. The driving motor 32 may be controlled by a control signal of a controller (not shown) to be described later.

As such, by including the lower groove 2 and the gate 3 and closing the rear of the lower groove 2 through the gate 3, the foreign matters in the waterway 12 are increased by increasing the space in which foreign matters can be accumulated. This flow is suppressed, and the time for accumulating foreign matters and the like (the time for depositing foreign matters and the like in the space between the bottom surface FS and the housing 11) is extended, and the flow velocity of the water channel 12 is increased to generate a turbine for power generation ( There is an advantage that it is possible to improve the power generation efficiency (not shown).

In addition, when foreign matters are accumulated in the lower groove 2 and foreign matter may flow into the channel 12, the foreign material may be discharged in the downstream direction by opening the rear of the lower groove 2 through the gate 3. There is this.

1 and 2, the hydro power generation system S may include a bypass 4 formed between the power generator 1 and the order wall CW. The front inlet of the bypass 4 is provided in front of the front end of the order wall CW, and the rear outlet of the bypass 4 can be provided behind the rear end of the order wall CW. Here, the front end means the front end, and means the upper end with reference to FIG. 1, and the rear end means the rear side and may mean the lower end with reference to FIG.

As described above, the hydroelectric power generation system S has an advantage that the living body such as salmon can be moved along the opposite direction of the water flow by including the bypass 4.

3 is a view for explaining the inflow preventing member and the removing member.

1 to 3, the power generator 1 may include an inflow preventing member 13 having a plurality of ribs 131 disposed at a front end of the water channel 12 and disposed at predetermined intervals. As described above, the front end is based on the moving direction of water, and the front end of the water channel 12 is a side end into which water flows into the water channel 12. That is, the left side may be referred to based on FIG. 2.

In this way, the generator 1 includes the inflow preventing member 13 at the front end of the channel 12 so that foreign matters larger than the predetermined interval (distance between neighboring ribs 131) flow into the channel 12. There is an advantage that can be suppressed.

Therefore, the predetermined interval is preferably small.

1 to 3, a rotation shaft 141 having both ends connected to both sidewalls of the channel 12, and a removal protrusion 142 connected to the rotation shaft 141 and protruding between the ribs 131. It may include a removal member 14 having a.

For example, the plurality of ribs 131 may be disposed at the predetermined intervals along the width direction, and the rotation shaft 141 may be in a direction parallel to the width direction, and thus the rotation shaft 141 may be a water channel ( 12 may be connected to both sidewalls forming a width of 12).

The removal protrusion 142 may protrude in the vertical direction from the rotation shaft 141 to rotate the rotation shaft 141 about the center axis between the plurality of ribs 131.

For example, the pivot shaft 141 may be disposed at a rear side of the front end of the rib 131. That is, the removal protrusion 142 is connected to the pivot shaft 141 disposed behind the front end of the rib 131, the end of the removal protrusion 142 is projected between the ribs 131 between the front end of the rib 131 It is provided to the front.

For example, the rotation shaft 141 may be driven by the driving unit 143, and the driving unit 143 will be apparent to those skilled in the art, so a detailed description thereof will be omitted.

The driving unit 143 may be controlled by a control signal of a controller (not shown) which will be described later.

As such, since the power generator 1 includes the removal member 14, there is an advantage that the foreign matter accumulated in at least one of the inflow preventing member 13 and the housing 11 can be easily controlled.

Although not shown, the controller (not shown) may be applied with various control configurations or computing devices (for example, various electronic devices or electronic modules such as computers, processors, etc.) known to those skilled in the art. For example, the controller (not shown) may be configured to transfer a signal (the control signal) or a command generated according to a program or algorithm included therein to the driving motor 32, the driving unit 143, or the like. For example, the control unit (not shown) is an intrinsic configuration included (installed) in the driving motor 32, the driving unit 143, or the like, or the driving motor 32 at a position adjacent to the driving motor 32, the driving unit 143, or the like. In addition, the driving unit 143 may be provided separately and connected to the driving motor 32, the driving unit 143, and the like by wire or wirelessly.

4 shows a further embodiment of the present invention.

1 to 4, as described above, the gate 3 is formed of a material in which water permeation is suppressed in order to improve the flow rate and flow rate in the water channel 12 in the closed state (closed state of the lower groove 2). It is said that it is preferable, but waterproofness is required.

In addition, in the closed state (closed state of the lower groove 2), the gate 3 may repeatedly come into contact with foreign matters such as sand, stone, tree branches, scratches, and the like. Large loads may be repeatedly applied by weight, moving water, and the like.

Therefore, the gate 3 may include a protective film G on an outer surface of the gate 3 to suppress the occurrence of scratches to improve waterproofness, to prevent scratches, and to prevent the outflow of foreign substances due to deformation and breakage.

Referring to FIG. 4, the protective film G will be described in detail. The gate 3 further includes a protective film G provided on an outer surface of the protective film G, and the protective film G is formed on the outer surface of the gate 3. In addition, the heat-generating layer (G2) provided on the upper portion of the penetration layer (G1) and the protective layer (G3) provided on the heat generating layer (G2) is characterized in that it may comprise.

Such a protective film (G) has excellent buffering and waterproofing effects in itself, and in particular, when electricity is applied to the heat generating layer (G2), the protective film (G) is heated to about 300 ° C., so that the penetration layer (G1) is melted, and thus fine pores or fine bends on the outer surface thereof. By sintering after filling, it not only has improved bonding strength, but also prevents lifting, thereby providing more robust protection and waterproofing (in the accompanying drawings, the micropores and microflexes are exaggerated).

In a specific embodiment, the permeation layer (G1) comprises 20 parts by weight of a polyvinyl acetate-based low-shrinkant and 50 parts by weight of a pressure-sensitive adhesive containing hydrogenated rosenester resin and polybutene, relative to 100 parts by weight of polyethylene.

For each of the compositions, polyethylene was added from the petroleum naphtha, added as a thermoplastic resin, and adopted in that it was excellent in water resistance and had a melting point of about 130 ° C. Each composition of the permeation layer (G1) is determined based on 100 parts by weight of this polyethylene.

In addition, the polyvinyl acetate-based low shrinkage agent is added as an anti-shrinkage agent for preventing the phenomenon of excessive contraction during the sintering of the penetrating layer (G1), and lifting occurs. It is preferable that such a polyvinyl acetate-based low shrinkage agent is included in 20 parts by weight. If the polyvinyl acetate-based low shrinkage agent is less than the above range, the shrinkage preventing effect is insufficient.

The pressure-sensitive adhesive is added to impart adhesiveness to the penetrating layer (G1) to reinforce the binding force in micropores, fine bends, and the like, and particularly includes a hydrogenated ester of Resin and polybutene. . The hydrogenated lozenster contributes heat resistance after sintering while imparting initial adhesion, and polybutene imparts tackiness. It is preferable that such an adhesive contains 50 parts by weight, but when it is less than the above range, the adhesive force is lowered, and when it exceeds the above range, there is a problem that the adhesiveness after sintering is sharply decreased.

The permeation layer (G1) is formed by injecting each composition into a polyethylene solution at a temperature of 130 ° C. or higher at which polyethylene can be melted, followed by sintering.

Next, the heat generating layer G2 includes 200 parts by weight of silver and 200 parts by weight of a functional binder including titanium dioxide and molybdenum dioxide, based on 100 parts by weight of ruthenium dioxide. The heat generating layer (G2) is characterized in that it is applied to the upper portion of the penetration layer (G1) in the form of a paste.

For each composition, ruthenium dioxide is a transition group of platinum group, which is provided in powder form to form a heat generating layer (G2) in the form of a paste. When the ruthenium dioxide is excessively used, since the exothermic temperature is too high to damage the protective layer G3 to be described later, the ruthenium dioxide is preferably not more than 20% by weight relative to the total composition of the exothermic layer G2. Each composition of the heating layer (G2) is determined based on 100 parts by weight of this ruthenium dioxide.

In addition, silver (Ag) is a transition metal, like ruthenium dioxide, and is provided in powder form to form a heat generating layer G2 in paste form. It is preferable that such silver is included in an amount of 200 parts by weight. When used below the above range, it is difficult for the heating layer G2 to have a sufficiently low resistance value for generating current, and when used over the above range, the heating temperature becomes excessive. There is.

And functional binders are added for the combination of ruthenium dioxide and silver, and additionally facilitate dispersal between the components and provide shortening of the exothermic saturation time and sustaining the exothermic effect. Functional binders include titanium dioxide and molybdenum disulfide. Titanium dioxide contributes to the sustaining of the exothermic effect. In particular, molybdenum disulfide is a compound in which the molar ratio of molybdenum and silicon is 1: 2. The heat generation layer (G2) is prevented from melting during heat generation, and silica is formed at a high temperature to shorten the heat generation effect and significantly shorten the heat generation saturation time. It is preferable that such a functional binder is included in 200 parts by weight, when used in less than the above range, the effect is insufficient expression, when used in excess of the above range occurs the problem of unstable electrical flow at high temperature exothermic.

The exothermic layer (G2) is ethylene glycol (terpene), butyl carbitol, ethyl cellosolve, ethyl benzene, isopropyl benzene, methyl ethyl ketone, dioxane, acetone, cyclohexanone, 3-methoxybutyl acetate, etc. It is prepared through a kneading process after mixing the compositions in an organic solvent.

Next, the protective layer G3 includes 300 parts by weight of a filler including calcium carbonate and bentonite, 100 parts by weight of naphthenic oil and 50 parts by weight of a heat resistant agent including barium aluminate and zirconia, relative to 100 parts by weight of butyl synthetic rubber. do.

For each composition, butyl synthetic rubber was employed in that it had appropriate cold resistance and heat resistance, was relatively high in elasticity, and was excellent in thermal insulation effect. The protective layer (G3) is determined based on 100 parts by weight of butyl synthetic rubber.

And fillers include calcium carbonate and bentonite, calcium carbonate is used to add water resistance, bentonite has a relatively good cation exchange capacity is possible to bond firmly, if the crack occurs in the protective layer (G3), moisture absorption It has the effect of preventing leakage while expanding through. In particular, the fillers are all composed of a composition having excellent binding strength can be made excellent compatibility between the protective layer (G3) and the penetration layer (G1). Such fillers are not particularly limited in use, but it is preferable to include 300 parts by weight in terms of increasing the bonding strength and economics.

And naphthene oil was added as a plasticizer, and it was employ | adopted in the point that there is little evaporation loss at high temperature, it is excellent in cold resistance, and can add an elastic retention effect. It is preferable that such naphthenic oil contains 100 parts by weight, and when used below the above range, flexibility and workability are lowered, and when it is used above the above range, the viscosity is excessively lowered so that the operation of the heating layer G2 is performed. Falling occurs in the air and a crying phenomenon of the protective layer G3 occurs.

And the heat resistant agent is added to add heat resistance so that the protective layer (G3) to withstand the heat generated by the heat generating layer (G2) without melting, in particular, the protective layer (G3) to withstand even at a high temperature of 300 ℃ or more. The heat resistant agent includes barium aluminate and zirconia, which is added as a binder for combining zirconia with other compositions, and zirconia has a melting point of about 2700 ° C., excellent resistance to rapid temperature changes, and at least 1000 It is added to allow the protective layer G3 to withstand low thermal conductivity, heat resistance, and fire resistance even at a high temperature of more than ℃. In particular, by the heat resistant agent, the protective layer G3 has a plurality of internal pores, and these pores lower the thermal conductivity and add heat resistance. It is preferable that such a heat resistant agent is included in 50 parts by weight, but when used outside the above range, the heat resistance is rather deteriorated.

The protective layer (G3) is prepared by mixing the naphthene oil with each composition in powder form, and may further include a predetermined functional additive as necessary.

In the embodiment relating to the construction of the protective film (G), the penetrating layer (G1) is laminated on the test block formed with the fine pores and fine bends, the heat generating layer (G2) is applied on the upper part, and then the protective layer on the top After stacking (G3), electricity was applied to the heat generating layer (G2) to form a protective film (G). As a result of cutting the test block having the protective film G formed thereon and observing the cross section enlarged, it was confirmed that the penetration layer G1 penetrated into the micropores and the fine bends and cured. In addition, the cross-cut test, scratching test, and internal invasiveness test through water spraying were performed on the formed protective film G, and the peeling rate was less than 0.5%, and the breaking rate was less than 3%.
