[0001] Hydraulic power generator using sea water [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydroelectric power generating apparatus using seawater, and more particularly, to a hydroelectric power generating apparatus using seawater that is installed in the sea and converts energy due to horizontal movement of seawater into electric energy.

Generally, hydroelectric power generation means a device for generating electric energy by driving a power generation device using potential energy or kinetic energy of flowing water according to the water level of the water.

Generally, these hydroelectric power plants produce electric energy by constructing a power plant in a position where a topographical large drop is formed in a river or a river. Recently, researches for producing electric energy using buoyancy in wave or water have been active .

Especially, recently, the risk of environmental pollution caused by nuclear power plants and thermal power plants has risen so much that they are paying more attention to hydroelectric power generation methods that do not cause environmental pollution.

However, since conventional hydropower generation has been mainly performed using topographical conditions or accompanied by large-scale construction, power loss is caused because it is located at a remote place from a city where power demand is high and power generation is carried out. Since it is a large-scale power generation system, there is a problem that it is difficult to produce electric energy by providing power generation facilities at a private level.

In addition, water flowing in rivers and streams is highly influenced by geographical location, and there is still a limit to stop development if a change such as drought occurs due to the change of local environment due to climate change.

In order to solve such a problem, the present invention is to provide a power generation device using basic characteristics of seawater as a device for inducing power generation by using horizontal movement energy (algae) of sea water constantly occurring as a natural phenomenon, , It induces the inflow of seawater artificially and draws it into the basement, changes the horizontal movement energy to the fall energy by using abundant seawater, produces electricity of hundreds (MW) in the first place, And it is an object of the present invention to provide a hydroelectric power generating apparatus which smoothly discharges seawater passing through a turbine to induce continuous power generation.

According to an aspect of the present invention, there is provided an air conditioning system comprising: a water intake unit disposed at a height at least equal to or higher than a height of a sea surface and introducing seawater into a land direction lower than a height of the sea surface; A converting unit converting the potential energy of the seawater supplied to the water intake unit into kinetic energy; A first power generation unit for generating electricity through kinetic energy of the seawater supplied from the conversion unit, and a drain unit for discharging seawater to the sea using kinetic energy of the seawater having passed through the first power generation unit Provide hydroelectric power generation equipment using seawater.

The water intake unit may include a water collecting tank for temporarily storing seawater at a height lower than the height of the sea surface, and a guide pipe connected to the water collecting tank so as to be inclined downward toward the conversion unit.

Wherein the conversion unit includes an outflow tunnel for supplying seawater to the first power generation unit from the rear end of the induction pipe and converting seawater into kinetic energy, and a bypass channel for discharging seawater to the sea before the seawater flows into the outflow tunnel, .

The conversion unit may include a first gate valve for controlling a speed or a flow rate of seawater passing through the free fall tunnel.

The first power generation unit may include a first turbine rotating by the sea water supplied through the free fall tunnel, and a first power generation unit producing electricity using the rotational force of the first turbine.

The drainage unit may include a water storage tank for storing the seawater having passed through the first turbine, a discharge pipe for discharging the seawater having passed through the first turbine to the sea without passing through the water storage tank, A second gate valve, a vacuum pump for providing discharge pressure to seawater discharged toward the sea through the discharge pipe or the reservoir, and a discharge induction pipe for discharging seawater from the vacuum pump toward the sea.

The hydroelectric power generation apparatus using seawater may further include a second power generation unit that generates electricity through kinetic energy of the seawater discharged through the drainage unit.

The second power generation unit includes a second turbine rotating by friction with seawater discharged toward the sea through a discharge induction pipe connected to the discharge pump, and a second power generation unit generating electricity using the rotational force of the second turbine And a second power generation section.

According to the hydroelectric power generation apparatus using seawater according to the present invention,

The abundant quantity of seawater can be used indefinitely for power generation regardless of tide or ebb. At the same time, seawater flow such as algae generated by natural phenomenon can be used as stable and effective environmentally friendly pollution-free power And can be a great alternative to the power generation method that uses chemical fuels.

In addition, by using the vacuum pressure of the discharge vacuum pump together with the dropping pressure of the seawater in the drainage part, the drainage can be smoothly performed with less force, the power consumption due to seawater discharge can be remarkably reduced and the supply amount of the electric power generation can be increased accordingly It is effective.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. It should be noted that the drawings denoted by the same reference numerals in the drawings denote the same reference numerals whenever possible, in other drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. And certain features shown in the drawings are to be enlarged or reduced or simplified for ease of explanation, and the drawings and their components are not necessarily drawn to scale. However, those skilled in the art will readily understand these details.

FIG. 1 is a block diagram of a hydroelectric generator using seawater according to an embodiment of the present invention, and FIG. 2 is a side view schematically showing a hydroelectric generator using seawater shown in FIG.

1 and 2, the hydroelectric power generation apparatus 100 using seawater according to the present invention includes a water intake unit 110 for drawing seawater to land, One or a plurality of first power generation units 130 for generating kinetic energy of seawater formed in the conversion unit 120 into electric energy, and a first power generation unit 130 One or a plurality of second power generation units 150 generating electricity again in the process of discharging seawater to the sea through the drainage unit 140 and the drainage unit 140 discharging (discharging) .

One part of the water intake part 110 is located in the sea, and the ground part is located on the land. Therefore, it draws sea water from the sea and supplies it to the land direction.

The water intake unit 110 includes a water collecting tank 111 disposed adjacent to the sea level and a guide pipe 114 connecting the water collecting tank 111 to the converting unit 120 to guide the inflow of seawater, (112).

Here, it is preferable that the water collecting tank 111 is located at a height lower than the height of the sea surface during low tide. In the water collecting tank 111, the flow rate of the seawater by the tide and the flow rate of the seawater by the tidal phenomenon are accelerated, and the seawater flows into the inside. The direction of the head (not shown) in which the seawater is introduced into the water collecting tank 111 may be changed according to the flow of the seawater or the seawater may flow in all directions because the direction of the seawater due to the tidal phenomenon may change. . Since the water collecting tank 111 is located at least at a height lower than the height of the sea surface, the amount of seawater can be secured for 24 hours, and sea water necessary for the production of electricity can be supplied for 24 hours.

The conversion unit 120 uses a large freefall to convert the potential energy of the seawater introduced from the water intake unit 110 into kinetic energy. Therefore, the conversion unit 120 is located on the land near the sea, and the conversion unit 120 and the first power generation unit 130 are disposed in the underground space of the land so that a large head is formed.

The first power generation section 130 turns the turbine with seawater falling by a large drop at the conversion section to produce electrical energy.

At this time, the sea water that has passed through the first power generation unit 130 is discharged to the sea through the roll of the drainage unit 140. There is no significant change in the flow rate of the seawater falling from the conversion unit 120 to the first power generation unit 130, Since the discharge vacuum pump 144 is operated in the drainage part 140, a large amount of seawater can be easily discharged to the sea by a small force due to the flow velocity of the seawater and the suction force of the vacuum pump.

Further, since the second power generation unit 150 can be operated using the pressure of the seawater discharged from the drainage unit 140, there is an advantage that additional electric energy can be produced.

Hereinafter, the configurations of the conversion unit 120, the power generation unit 130, and the drainage unit 140 and the effects and effects of the conversion unit 120 will be described in detail.

FIG. 3 is a reference view showing a conversion unit of the hydroelectric power generation apparatus using the sea water shown in FIG. 2, and FIG. 4 is a reference view showing a power generation unit and a drainage unit of the hydroelectric power generation apparatus using the sea water shown in FIG.

3 and 4, the conversion unit 120 includes an outflow tunnel 121 for supplying sea water supplied from the water intake unit 110 with a large head in the direction of the first power generation unit 130, A bypass flow path 122 for discharging the seawater supplied from the first power generation unit 110 to the sea before supplying the first power generation unit 130 with the seawater, (123).

The free fall tunnel 121 connects the first power generation unit 130 having a drop of about several tens of meters from the conversion unit 120, for example. Of course, it is possible to control the cross-sectional area and the fall-off width of the outflow tunnel 121 according to the size of the power generation. In the present invention, it is preferable that the free fall tunnel 121 forms an about 25 to 100 m drop from the collecting tank 111 or the converting unit 120 in the direction of the underground.

The bypass channel 122 is connected between the rear end of the induction pipe 112 and the off-ice tunnel 121 to discharge seawater to the sea. The bypass flow path 122 provides a function to artificially block the passage of the seawater in the direction of the off-ice tunnel 121 by stopping the operation of the first power generation unit 130 or bypassing the seawater to the sea during the inspection.

The first gate valve 123 includes a first valve 124 provided at the front end of the lift tunnel 121 and a second valve 125 provided at the rear end.

The first valve 124 provided at the front end of the free fall tunnel 121 completely blocks the free fall tunnel 121 when the bypass flow path 122 described above is opened to bypass the seawater. Also, the first valve 124 can control the flow rate of the seawater flowing into the fall tunnel 121 when the bypass flow path 122 is shut off. For example, the first valve 124 may maintain the pressure or velocity of the seawater passing through the fall tunnel 121 constant, or may control the speed at which the seawater is supplied corresponding to the speed of the algae, either rapidly or slowly during a set period of time have.

The second valve 125 provided at the rear end of the free fall tunnel 121 functions to shut off the seawater flowing into the first power generator 130. For example, the second valve 125 may bypass the first power generation section 130 and bypass the seawater to the drainage section. Alternatively, when the first power generation section 130 is inspected or maintained, It is possible to block the influx of seawater from the source.

The first power generating unit 130 includes a first turbine 131 rotated by the sea water supplied through the second turbine 121 and a first power generating unit 130 for generating electric energy using the rotational force of the first turbine 131. [ (132).

Here, the seawater is formed to have a loss rate due to the resistance of the first turbine 131 in a range of about 0.6 to 0.8. This is because if the resistance of the sea water and the first turbine 131 further increases, the first turbine 131 may be damaged or unreasonable, and if the resistance is reduced, ) Or a rate of loss of kinetic energy of about 0.7.

The first power generation unit 132 rotates either one of the coils (not shown) or the magnet (not shown) using the rotational force of the first turbine 131 and the other one is electrically connected to the coil, .

The drainage unit 140 includes a water storage tank 141 in which the seawater having passed through the first turbine 131 is stored and a discharge pipe 142 in which the seawater having passed through the first turbine 131 is discharged directly to the sea without passing through the water storage tank 141 A second gate valve 143 for controlling the direction of the seawater having passed through the first turbine 131 to one of the discharge pipe 142 and the water storage tank 141 and a second gate valve 143 for controlling the direction of the sea water passing through the discharge pipe 142 or the water storage tank 141 And a discharge induction pipe 147 for discharging seawater from the discharge vacuum pump 144 to the sea side.

The water storage tank 141 is a space where the seawater flowing through the first power generation unit 130 temporarily flows and is stored, and is located at the lowermost side in the land underground space. The size of the water tank 141 is determined according to the size of the power generation, and can store several thousands of tons of seawater at several thousand tons.

The seawater flowing into the water storage tank 141 is added to the speed of the seawater flowing through the fall-off tunnel 121 and the vacuum pressure from the vacuum pump 144 to increase the seawater from the water storage tank 141, (Discharge) is performed. Therefore, the water storage tank 141 is provided in a completely closed structure so as to maintain the vacuum pressure of the discharge vacuum pump 144.

Herein, the discharge pipe 142 is connected to the discharge inducing pipe 147 so that the seawater passing through the first power generating unit 130 is not introduced into the water storage tank through the falling tunnel 121 but flows directly through the discharge vacuum pump 144 . Therefore, when the amount of seawater passing through the free fall tunnel 121 is not required to be stored in the reservoir, the drainage resistance is directly connected to the discharge pipe 142 having less drain resistance, and drained to the sea through the discharge induction pipe 147.

The second gate valve 143 may include a third valve 145 provided between the first power generation unit 130 and the water storage tank 141 and a third valve 145 disposed between the discharge vacuum pump 144 and the water storage tank 141. [ And a valve 146.

The second valve 143 closes the third valve 145 when the seawater is directly connected to the discharge pipe 142 without passing through the water storage tank 141 in the first power generation unit 130, A vacuum pressure is applied so that the seawater supplied from the first power generation unit 130 is discharged to the discharge induction pipe 147 through the discharge pipe 142 and the fourth valve 146 is closed. The third valve 145 is opened when the seawater is supplied from the first power generation unit 130 to the water storage tank 141 and the discharge vacuum pump 144 is stored in the water storage tank 141 A vacuum pressure is applied so that seawater is discharged to the discharge induction pipe 147 and the fourth valve 146 is opened.

Therefore, since the seawater having passed through the first power generation unit 130 and having undergone the first power generation is drained by using the vacuum pressure of the discharge vacuum pump 144 along with the falling speed of the fall-off tunnel 121, The power loss due to the drainage can be remarkably reduced.

The discharge induction pipe 147 is connected to discharge seawater from the discharge vacuum pump 144 toward the sea. At this time, the second power generation unit 150 is provided on the discharge induction pipe 147 to receive the rotational force by the seawater discharged using the vacuum pressure of the discharge vacuum pump 144.

The second power generation unit 150 includes a second turbine 151 that rubs against sea water discharged to the sea through a discharge induction pipe 147 connected to the discharge vacuum pump 144, And a second power generation unit 152 that generates electricity using the power generation unit.

The second power generation unit 150 provides the same structure and effects as those of the first power generation unit 130, and redundant description thereof will be omitted. However, the second power generation unit 150 may be smaller in size than the first power generation unit 130. In addition, the electricity generated by the second power generation unit 150 can cover all the electricity required for the hydroelectric power generation apparatus 100 using the seawater of the present invention, so that all the electricity generated by the first power generation unit 130 can be supplied to the customer . Therefore, the larger the scale, the more electricity it can produce and the 24-hour electricity can be produced, which can replace the current universal power generation system using nuclear or fossil fuels, and the environmentally friendly There is an effect that the power generation facilities can be operated.
