[Document 11] Electric Power Engineering (co-authored by Kyu-Hong Hong)

The conventional tidal power generation system uses a simple stream of algae or a horizontal moving algae by constructing an embankment on the coast connected to the bay and the bay or the estuary, as in the case of the Lance power plant in France and the Sihwa Lake tidal power plant in Korea. Install a rotating wing (impeller) or screw type propeller to drive tidal power using the horizontal movement energy of tidal current caused by the difference between tides or tidal power generation or install a generator shaft in the underground space of the bank. It has been developing power and wave at the same time by using the pressure difference of air generated by wave force caused by tide movement, but it has changed the marine ecosystem by blocking the flow of algae due to the construction of levees, and it has failed to improve the efficiency of power energy production. There was a disadvantage

1.Increase the speed of existing tidal flow and environmentally friendly development

The present invention compensates for the slowing of the natural flow rate of algae at about 5 knots per hour, blocking only about 1 hour every 6 hours of inter-high tide crossings, and assuming that the difference between the high and low tide levels is an average of 6 meters. If you wait for 1 hour, the water level rises by about 1 meter, and the water gate is temporarily blocked for 1 hour every 6 hours, and the remaining 5 hours are developed with the water gates open. Minimized eco-friendly development

2.Increase the number of rotation of shaft of power turbine and improve the power output

If a large flat plate circular gear is installed on the top of the tumbler shaft mounted between the gate and the gate, and the gear acceleration ratio of the generator rotary shaft connected to the tumbler circular gear is 1:10, assuming that the tumble shaft rotates 60 times per minute The rotating shaft rotates 600 times per minute to improve the power generation efficiency according to the increase of generator rotational energy.

3. Recover or increase the power lost in the pumping process to the dam.

It is possible to recover the same power as the primary source power generation by placing the generator in the section extending from the pumping dam to the length of the drainage in the process of pumping the power generated from the primary source power on the rotational axis of the floodgate from the reservoir to the reservoir. It is possible to produce more power in the secondary stable power generation than the original power generation by increasing the generator in the same size drainage.

4. Easy to replace, repair and reduce power plant construction cost

When installing a reservoir on land, the bottom of the reservoir is excavated to the same height as the bottom of the sea at low tide, and the soil is installed on the bottom of the reservoir to conserve the construction cost. Since the quantity of water must be secured at least 6 hours and maximum 72 hours, the dam size does not have to be too large, so it is less expensive than the construction of hydroelectric and thermal power plants. If installed, the top plate can be utilized as a bridge, and using the flame-resistant steel pipe pile, the pile is piled on the wall surface to be added prefabricated, so that the installation shaft can be additionally installed in the horizontal and vertical directions.

Hereinafter, the accompanying drawings will be described in detail.

1 is a schematic diagram of tidal power generation device (detailed three-dimensional diagram)

① Sluice

The gate is equipped with an automatic sensor switch on the top, and is installed to open in the same direction as the direction of the tidal current and close in the vertical direction of the tidal flow according to a certain time. Install

A. Gate opening / closing time and adjustment table (when high tide is 00:00 and low tide is 06:00)

B. How to control the gate

The automatic opening and closing sensor is attached to the upper part of the water gate, adjusts the time, and opens and closes. Since the tidal flow is slow 1 hour before the end of the high tide, stop the power generation, wait until the high tide is over and start the low tide, and let the tide flow. Close and wait for 1 hour, then open the sluice at once with algae rising about 1 meter, generate power up to 1 hour before the end of low tide, and open the sluice at the intersection of low and low tide for 1 hour until the end of low tide. Wait and close the floodgate at the time of inter-high tide crossing. Like this, it repeats and develops according to the high tide time. Power generation time is 4 hours every 6 hours. Power generation is 16 hours a day. The waiting time is 1 hour every 6 hours and the time when the gate is closed is 1 hour every 6 hours. During the one hour of hydrological closure, free fall energy is generated as the level of algae rises in the algae's horizontal movement energy, which increases the algae speed and power, improves the power output, and increases the amount of dissolved oxygen in the algae that passes through the hydrologic by the rapid algae. When newly formed and installed at sea, it can help to create coastal marine fish stocks, and the ground pumping dam has characteristics and advantages that can be used as a fish farm for various marine fish stocks because new algae are circulated for 24 hours.

② Rotating blades of current rotation shaft (impeller)

end. Structure of rotating wing

Rotating blades are S-shaped symmetrical with respect to the tidal axis of rotation and are installed to maintain a constant direction of rotation at all times during high tide and low tide. It should be installed perpendicular to the axis of rotation and horizontal to the direction of tide. The concave shape increases the resistance of the algae, and the outer side is V-shaped, and the algae resistance is small by the rotation, so that the rotational axis of the algae rotates smoothly in a certain direction along the algae that is pushed through the water gate.

I. Number of rotating feathers

The number of wings on the tidal axis is more than 6 or 4 leaves depending on the size of the floodgate and the difference between the tidal flows of birds. Can be installed

All. Width and vertical gap of rotary blade

For example, if the upper and lower widths of the wings are set to 50 cm on the rotating shaft, the upper and lower gaps between the lower wing and the upper wing are 50 cm apart as the width of the wings, while the birds are smoothly distributed between the upper and lower gaps of the wings, but the resistance received by the birds is reduced. Install at even intervals up to the height of the high water level at the bottom of the intermediate plate connection

③ Rotating Gear of Upper Disc

In order to increase the rotational energy of the tide shaft, the outer diameter of the circular plate gear on the top of the tide shaft should be installed to the maximum diameter within the width of the gate.

④ Generator rotating shaft

In order to increase the speed energy due to rotation by engaging the gear of the tidal shaft, the gear of the generator shaft should be installed within the minimum range of 20cm in diameter. Assuming that the gear shaft diameter of the generator is 0.1, the gear ratio is 1:10. When the tidal shaft rotates once, the generator shaft rotates 10 times. If the tidal shaft rotates 60 times, the generator shaft rotates 600 revolutions per minute. It is effective to increase power generation efficiency by increasing rotation speed energy. The interconnection of tidal axis and generator rotation axis can be replaced by chain or special rubber belt.

⑤ Supports on the lower side of the tidal current rotating shaft and on both walls

Both sides of the wall are equipped with flame resistant steel frame support, and the connection part of the lower part of the tidal rotation shaft is installed with flame resistant special steel bearing to improve the robustness and durability of the generator.

⑥ Top plate of generator

If the top plate is installed by steel plate and the bay and bay are connected to the sea and installed in the lateral direction, the top plate is installed firmly in consideration of the vehicle load of the wall and the top plate so that it can be used as a bridge.

⑦ Power Generation Unit

It is a space that installs a gear generator, such as a tumbler shaft, and manages power generation devices such as repair and repair. It is installed in a flameproof steel plate structure with a height of at least 2m that humans can walk around.

⑧ Lower part of generator

If it is installed on land, it can be installed with reinforced concrete. If it is installed at sea, the floor and wall can be installed in steel plate structure, and the wall can be installed in various forms by piled at regular intervals.

end. When installed on land

In case of installation on the land, if the width of the gate is 5m, the vertical wall is installed vertically with reinforced concrete tank of 30cm width, and the concrete wall is installed between the gate and the gate on the floor, and the steel frame is vertically on the floor and wall. Install the rotating shaft by connecting the upper and lower ends to each other by attaching the support, and the horizontal rotating bearings on the upper and lower ends of the rotating shaft, and install the interlocking gear with the rotating shaft of the generator on the disk gear on the top of the rotating shaft to rotate the generator.

I. When installing at sea

In case of installation on the sea, the pile is fixed in the middle of the wall of the power generating device. The piles are connected horizontally and vertically to the bottom, center and top of the pile by flameproof steel pipes between the piles. The vertical support is installed at the top and bottom of the wall, and the horizontal rotation bearing is installed at the middle point of the vertical support at the bottom of the power generating device. It is connected to the tidal axis in the vertical direction, and the horizontal rotation bearing is installed at the top of the tidal axis. The wall and the bottom of the power generation unit where the algae communicates are connected by flameproof steel sheet.

The rotor blade blade is S-symmetrical and V-shaped on the inside to increase the current resistance during rotation and to reduce the resistance on the outside.

5 is a plan view of the land arrangement structure of the tidal power generation device

① Sluice

Water gate 1 columns and 2 can be installed to the side columns, or three rows or more, and in proportion to the water storage tank and pumping tank size and power water amount and installed in various forms ①-1 is a bird inflow direction at high tide ①-2 is birds during low tide Inflow direction

② reservoir

It is a space where algae flow in and out for primary development.

③ Campground

It is a place to pump seawater to the water tank by using the electric power after the 1st power generation. The water is drained from the sea surface outside the reservoir.

④ Pump tank

It is a freshwater space for stable power generation 24 hours a day, 7 days a week. Fresh water is stored at a pumping station for 4 hours during 6 hours of high tide. Fresh water capacity is at least 24 hours. Considering the amount secured, it can be installed to allow more than 72 hours of fresh water.

⑤Drainage for power generation

If the water gate and reservoir are installed on the land for 24 hours continuous power generation, the water gate and the tidal axis can be installed in a straight line, and several generators can be arranged in the drainage passage through the pumping dam within the range of the drainage length. As a result, the power generation is increased and the power lost in the process of pumping the first-generation power generated at the inlet of the reservoir into the pump can be recovered. When installed at an inclination angle of about 3 to 5 degrees depending on the installation terrain, the power generation efficiency is increased due to the increase in drainage flow velocity energy.

The function of each part is as shown in [Figure 7].

It converts the horizontal moving energy of tidal currents into tidal current to increase tidal power and produces semi-permanent power without discharging pollutants by using natural tidal power. By inventing power generation principles that improve recovery and power generation efficiency, it is possible to construct various types of tidal power plants by large, medium, and small scale depending on the topographical conditions of the coast, thus reducing the cost of power plant construction and leaving radioactive waste disposal problems after power generation. It has the effect of protecting the global ecosystem and preserving the pleasant living environment of human beings by substituting thermal power generation that causes global warming by CO2 generation in the development and development process.
