Description

Hydroelectric power generation structure capable of flow control and flow control method using the same {A HYDROELECTRIC POWER GENERATION STRUCTURE CAPABLE OF FLOW CONTROL AND FLOW CONTROL METHOD USING THE SAME}

The present invention relates to a hydroelectric power generation structure capable of flow control and a flow control method using the same. More specifically, a hydroelectric power structure capable of flow control and the same, which are configured to easily control the opening and closing of gates for entry and exit according to the water flow rate. This relates to the flow control method used.

In general, hydropower (underwater) power generation has the advantage of being a renewable energy that does not emit environmental pollutants, unlike thermal power generation or nuclear power generation. However, there is a problem that the terrain where large amounts of water can flow and obtain high potential energy is very limited, and the construction of dams or seawalls incurs very large costs and causes environmental damage. Additionally, there is a disadvantage in that it is difficult to ensure stable electricity production when there is a difference in flow rate depending on the season.

In addition, the hydroelectric power generation system is largely dam-type power generation (including channel-type power generation and small hydro power generation) that generates power by turning a water wheel while trapping and releasing water, tidal power generation using the drop caused by changes in sea level due to tidal waves, and the flow of ocean currents or tidal waves. It can be classified as tidal power generation using the flow of water generated by the difference.

However, in the case of hydroelectric power generation, a dam that stores a vast amount of water is required, so it can only be applied in limited areas, which imposes restrictions on the installation location. In addition, in the case of a conventional hydroelectric generator, electricity is obtained by rotating a turbine using the drop of water at a high position, so water storage facilities such as dams, power generation facilities installed below the dam, and water used for power generation are collected from rivers or rivers. Since drainage facilities to send to the sea had to be built on a relatively large scale, there was a problem that a lot of installation space and installation costs were required.

Therefore, in recent years, research and development on small hydro power generation devices capable of producing electricity through small flowing water have been actively conducted.

If the river flow rate is above a certain level, there is an urgent need to develop a hydroelectric power generation device that is easy to install without requiring large-scale civil engineering work like a dam and can solve both economic and environmental issues.

Hereinafter, a flow rate control method using a hydroelectric power structure capable of flow rate control according to the present invention will be described.

Figure 10 is a block diagram showing the configuration of a flow rate control method using a hydroelectric power generation structure capable of flow rate control according to the present invention.

The flow rate control method using a hydroelectric power structure capable of flow rate control according to the present invention may include a flood control step (S100) and a constant control step (S200) as shown in FIG. 10.

Figure 6 is a diagram showing the second gate opening process and the first gate opening process of the flow control unit when a flood occurs, Figure 8(a) is a diagram showing the waterway guide plate lowering process of the waterway unit when a flood occurs, and Figure 11 is a diagram showing the process of lowering the waterway guide plate when a flood occurs. This is a block diagram showing the configuration of the flood control stage according to the invention.

In the flood control step (S100) according to the present invention, as shown in FIGS. 6, 8(a), and 11, when the water flow amount is more than a preset reference value, the flow control unit 100 and the waterway unit 200 This is a configuration that controls the operation, and in the event that flooding occurs in the flow control unit 100 of the hexagonal pillar that performed the function of a stepping stone, the four surfaces where resistance occurs are removed to reduce resistance.

Specifically, in the flood control step (S100), not only the flow to the waterway unit 200 but also the flow through the first gate 110 and the second gate 120 of the flow control unit 100 is shown in the amount of water required. In the configuration applied to this case, the flow control unit 100 opens the first gate 110 and the second gate 120, and the water channel unit 200 opens the first water channel guide plate 210 and the second water channel guide plate 210. The plate 220 is lowered to allow a large amount of water to flow.

In this case, the cover part 140 of the flow control unit 100 is moved upward so that the first gate 110 and the second gate 120 can be opened, and the rotation water turbine 231 is also moved upward to generate power. The operation of the member 230 can continue to develop or be stopped while rising according to changes in flow rate.

(312) This is a process in which the second gate 120 is opened when it is wound and pulled by a motor. It is performed before the first gate 110 is opened, so that the second gate 120 can be easily opened while the water pressure is relatively low. make it possible

The first gate opening process (S130) is a process in which the first gate 110 is opened by unwinding the first chain 321 and moving the first gate 110 backward into the internal space by hydraulic pressure.

Specifically, the first gate opening process (S130) is a process of opening the first gate 110 after the second gate 120 is opened. As shown in FIG. 6, the first gate (②) 110 is opened. This is a process in which when the first chain 311 is disconnected or the wound first chain 321 is unwound, the first gate 110 is pushed rearward by water pressure and the first gate 110 is opened.

Additionally, the opened first gate 110 is fixed to a set groove so that it can be maintained in an open state.

As this process progresses, the side that causes water resistance among the hexagonal pillars of the flow control unit 100 is folded, allowing water to directly penetrate the inside of the flow control unit 100, creating a water channel in the center.

The aberration raising process (S140) is a process of increasing the rotation aberration (231).

The waterway guide plate lowering process (S150) drives the third axis 313 motor 310a to move the support member 240 downward to move the first waterway guide plate 210 and the second waterway guide plate 220. This is a process of moving downward to the ground.

Specifically, the waterway guide plate lowering process (S150) is performed by rotating the left and right rotating plates 328 in a chain manner by rotating the third axis 313 of the waterway unit 200 to lower the lower end of the connecting pillar 329. The bevel gear 326 is rotated and the screw protrudes to lower the third support 243, and the third chain 323 is unwound to sequentially lower the first support 241 and the second support 242. The first waterway guide plate 210 and the second waterway guide plate 220 can be lowered to the floor.

That is, the support member 240, the first waterway guide plate 210, and the second waterway guide plate 220 are lowered by rotation of the third axis 313, thereby significantly lowering the water resistance. .

Therefore, by lowering water resistance as much as possible, immediate recovery after a drop in water level is possible without dismantling facilities in the event of a flood, enabling semi-permanent power generation.

Specifically, the regular control step (S200) is a configuration applied when a water flow amount that does not require flow through the first gate 110 and the second gate 120 of the flow control unit 100 appears, The flow control unit 100 closes the first gate 110 and the second gate 120, and the water channel unit 200 raises the first water channel guide plate 210 and the second water channel guide plate 220. Allow an appropriate amount of water to flow.

More specifically, the regular control step (S200) is a step performed when the flood is over and the water level is lowered, and the cover portion 140 is lowered and the height of the support member 240 is increased by rotation of the third axis 313. This is the rising stage.

In this case, the first gate 110 and the second gate 120 are closed, the cover part 140 of the flow control unit 100 is moved downward, and the rotation water turbine 231 is also moved downward to form the power generation member 230. ) so that the operation can be achieved.
