[Effects of the Invention]

[0011] The dam power generation system of this invention, which protects the environment with clean energy, is supplied with water from the ocean and does not rely on freshwater from rainfall. [Brief explanation of the drawing]

[0012] [Figure 1] This is an explanatory diagram showing a clean energy dam power generation system that protects the environment, according to one embodiment of the present invention. [Figure 2] This is a perspective view showing a shallow dish-shaped worm gear for a clean energy dam power generation system that protects the environment, according to one embodiment of the present invention. [Figure 3] This is a perspective view showing the first turbine of a clean energy dam power generation system that protects the environment, according to one embodiment of the present invention. [Figure 4] This is a block diagram showing a clean energy dam power generation system that protects the environment according to one embodiment of the present invention. [Modes for carrying out the invention]

[0013] Refer to Figures 1 to 4. As shown in Figures 1 to 4, a clean energy dam power generation system that protects the environment according to one embodiment of the present invention is installed near the coast E of the ocean C and comprises a reservoir 1, two power generation systems, and a power generation mechanism A.

[0014] Reservoir 1 is installed in the ocean C, with the coastline E serving as one side of the reservoir 1. Reservoir 1 has at least one inlet gate 11. In this embodiment, reservoir 1 is formed in a rectangular shape, uses the coastline E as one side, and has two inlet gates 11.

[0015] The two power generation systems are installed in parallel. Each power generation system includes a diversion channel 12, a first inlet channel 2, a first hydroelectric power module 3, a second hydroelectric power module 4, and two first outlet channels 5. Each diversion channel 12 is located within the reservoir 1. Each diversion channel 12 includes a trumpet-shaped inlet 13. The wide end of each trumpet-shaped inlet 13 faces the ocean C, and the narrow end of each trumpet-shaped inlet 13 faces the interior of the diversion channel 12. Each wide end is higher than each narrow end. Each wide end is lower than the high tide line, so seawater flows in naturally at all times. A first offshore hydroelectric power unit 14 and a second offshore hydroelectric power unit 15 are located within each diversion channel 12. Each second offshore hydroelectric power generation unit 15 is installed behind each first offshore hydroelectric power generation unit 14, and each first inlet channel 2 has a first inlet end 21 and a first outlet end 22. Each first inlet end 21 is connected to the outlet of each intake channel 12. Each first inlet end 21 is inclined downward and diagonally forward at a predetermined angle and extends to each first outlet end 22. Multiple first turbines 23 are provided at intervals between each first inlet end 21 and each first outlet end 22. Each first hydroelectric power generation module 3 has a first hydroelectric inlet end 31, a first hydroelectric power generation unit 32, and a first hydroelectric outlet end 33. Each first hydroelectric inlet end 31 is connected to each first outlet end 22. Each second hydroelectric module 4 has a second hydroelectric inlet 41, a second hydroelectric unit 42, and a second hydroelectric outlet 43. Each second hydroelectric inlet 41 is connected to each first hydroelectric outlet 33. Each first outlet channel 5 is located on either side of each first inlet channel 2. Each first outlet channel 5 includes a connecting section 51, a plurality of first ascending sections 52, a plurality of first descending sections 57, and a second descending section 53. Each first descending section 57 is installed between the first ascending sections 52 and, by assembly, forms an upward-extending staircase structure. Each connecting section 51 is connected at one end to each second hydroelectric outlet 43 and at the other end to the first first ascending section 52 on each side. The other end of the last first ascending section 52 of the first outflow channel 5 on both sides is connected to each second descending section 53, respectively.Each second lowering section 53 has an outlet 54 connected to the reservoir 1. Each first rising section 52 has a shallow dish worm 55. Both ends of each first turbine 23 are connected to each shallow dish worm 55 via a drive shaft 24. Each shallow dish worm 55 is connected to a motor 56. Each first offshore hydroelectric power generation unit 14, each second offshore hydroelectric power generation unit 15, each first hydroelectric power generation unit 32, and each second hydroelectric power generation unit 42 are electrically connected to their respective motors 56 or public grid equipment B, and the power generated by the collision of seawater with the first turbine 23 and the respective motors 56 work together to rotate each shallow dish worm 55 and discharge seawater into the reservoir 1.

[0016] The power generation mechanism A is located underground. The power generation mechanism A houses each first inlet channel 2, each first hydroelectric power generation module 3, each second hydroelectric power generation module 4, and each first outlet channel 5. Each trumpet-shaped inlet 13 is provided with a filter (not shown) to prevent foreign matter from the ocean C from entering the power generation system of the present invention.

[0017] In this embodiment, the inlet gate 11 of the reservoir 1 opens to allow seawater to flow in when the tide is high, but is kept closed during normal times to maintain the water level of the reservoir 1 at the high tide line. Each outlet 54 is higher than the high tide line, and water can be replenished twice a day at high tide, so the present invention does not suffer from water shortage problems. The closed water area of ​​the reservoir 1 prevents the potential danger to the open water area from occurring due to the vortex generated when seawater flows into the present invention. The trumpet-shaped inlet 13 accelerates the speed at which seawater flows in, and the intake channel 12 is tilted downward and diagonally forward. Multistage hydroelectric power generation is performed by the first off-sea hydroelectric power generation unit 14, the second off-sea hydroelectric power generation unit 15, the first hydroelectric power generation unit 32, and the second hydroelectric power generation unit 42 in the power generation system. The intake channel 12 and the first inlet channel 2 are formed with tapered pipe diameters, accelerating the flowing seawater downward. The connecting section 51 at the rear of the second hydroelectric power generation unit 42 divides into two smaller pipes, each connected to the first rising section 52 of the first outflow channel 5. When the seawater in each connecting section 51 is pushed upward, it is ejected into the first rising section 52 of the first outflow channel 5, where the first turbines 23 and motors 56 drive the shallow dish-shaped worms 55, helping to return the seawater to the reservoir 1. Each power generation system supports the others in terms of power and drainage.

[0018] Since the turbines of each first offshore hydroelectric power generation unit 14 in this embodiment are smaller than the turbines of each second offshore hydroelectric power generation unit 15, it is possible to prevent each second offshore hydroelectric power generation unit 15 from being obstructed by each first offshore hydroelectric power generation unit 14.

[0019] In this embodiment, the first lowering section 57 is located between two first rising sections 52, so the number of first lowering sections 57 is less than the number of first rising sections 52. The vertical height to which each first lowering section 57 descends in this embodiment may be less than the vertical height to which each first rising section 52 rises. Each second hydroelectric power generation unit 42 in this embodiment is located below each first hydroelectric power generation unit 32.

[0020] The power generation mechanism A of this embodiment is installed inside the levee D on the coast E side. As can be seen from FIG. 2, the water receiving surface 551 of the shallow dish-shaped worm 55 adopted in this embodiment is in a shallow dish shape. That is, the water receiving surface 551 is slightly sunken inward, and can move seawater more smoothly than a general worm, not in a straight line.

[0021] A gap 25 may be formed between the first waterwheel 23 of this embodiment and the pipe wall of the first water inlet 2. Through this gap 25, part of the seawater in the first water inlet 2 can directly pass through without hitting each first waterwheel 23 (not used to push the first waterwheel 23), and a certain impact force of seawater on the first hydraulic power generation unit 32 and the second hydraulic power generation unit 42 can be maintained. Each first waterwheel 23 may be a horizontal axis type waterwheel shown in FIG. 3 respectively. The number of the first waterwheels 23 may be the same as the number of the first rising section 52 and the shallow dish-shaped worms 55. Both ends of the rotating shaft of each first waterwheel 23 are mechanically connected to each drive shaft 24 respectively. For example, gears with different angles are used to transmit the force generated when each first waterwheel 23 rotates to each drive shaft 24 by changing the angle. Each drive shaft 24 is mechanically connected to each shallow dish-shaped worm 55, and helps each corresponding shallow dish-shaped worm 55 to be rotated by each first waterwheel 23 respectively. The rotation of each first waterwheel 23 and the motor 56 jointly rotate each shallow dish-shaped worm 55 to discharge seawater.

[0022] As can be seen from FIG. 4, one of the plurality of second hydraulic power generation units 42 of the power generation system of this embodiment is electrically connected to the public grid facility B to output the electric power generated by the present invention. Each motor 56 of the power generation system on the left side of FIG. 4 is electrically connected to the first hydraulic power generation module 3 in the other power generation system on the right side, so that the power generation systems cooperate with each other to drain water. The present invention performs multi-stage hydraulic power generation by each first off-levee hydraulic power generation unit 14, each second off-levee hydraulic power generation unit 15, each first hydraulic power generation unit 32 and each second hydraulic power generation unit 42, and helps to drive each shallow dish-shaped worm 55 by each first waterwheel 23 and each motor 56, and discharge seawater into the water storage tank 1 through the water outlet 54.

[0023] In this embodiment, each first off-dike hydroelectric power unit 14, each second off-dike hydroelectric power unit 15, and each second hydroelectric power unit 42 are each a horizontal-axis waterwheel generator. Each first hydroelectric power unit 32 is a vertical-axis waterwheel generator and can correspond to different water head heights. The waterwheels used for each first off-dike hydroelectric power unit 14, each second off-dike hydroelectric power unit 15, each first hydroelectric power unit 32, and each second hydroelectric power unit 42 may be Pelton waterwheels, Francis waterwheels, or Kaplan waterwheels.

[0024] As can be understood by those skilled in the art of this field, although the preferred embodiments of the present invention have been disclosed as described above, these are by no means intended to limit the present invention. Various changes and modifications can be made without departing from the gist and scope of the present invention. Therefore, the scope of the claims of the present invention should be interpreted broadly to include such changes and modifications.
