As shown in Figures 1 and 2, after the penstock 11 introduces seawater, the seawater generator set 12 is driven by the seawater to operate and generate electricity; in more detail, the weir area 1 of the utility model can be set at sea level or below sea level. If the weir area 1 is set at sea level, the penstock 11 needs to extract seawater through a pumping mechanism for the seawater generator set 12 to generate electricity; when the weir area 1 is set below sea level, the penstock 11 naturally introduces seawater to the seawater generator set 12 to generate electricity. In addition, the water inlet end of the penstock 11 can adjust the water inlet width. In addition, as shown in Figures 2 and 3, the penstock 11 increases the width on one side of the seawater generator set 12, and then multiple groups of seawater generator sets 12 are configured to generate electricity.

In addition, the pressure steel pipe 11 is not only a steel pipeline as shown in the figure, but in some embodiments, the pressure steel pipe 11 can be split to supply multiple seawater generator sets 12 for power generation at the same time.

As shown in FIGS. 3 to 5 , the seawater generator set 12 comprises:

The invention is composed of a turbine 121, an axis 122 arranged concentrically with the turbine 121, a speed change gear box 123 connected to the axis 122, and a generator 124; the turbine 121 is provided with a plurality of blades, and the seawater guided by the pressure steel pipe 11 impacts the blades of the turbine 121, so that the turbine 121 rotates, thereby driving the axis 122 concentric with the turbine 121 to rotate.

As shown in FIG. 3 and FIG. 4 , the speed change gearbox 123 is connected to the shaft 122 and the generator 124 respectively; a plurality of gear sets (not shown) are arranged in the speed change gearbox 124, and by switching the gear positions, the output shaft 125 connected to one end of the generator 124 generates a high speed or a low speed, thereby achieving a double power generation effect.

As shown in Figures 3 and 4, the generator 124 is connected to the speed change gear box 123. The generator 124 is driven by the output shaft 125 of the speed change gear box 123, so that the internal coil is excited to produce an electromagnetic reaction, thereby generating electrical energy. The generator 124 is also connected to a power grid 4, and the generated electrical energy is output through the power grid 4. The power grid 4 can convert the electrical energy into ultra-high voltage electricity and transmit it to ultra-high voltage substations in various places. Then, after the voltage is adjusted by the primary substation and the secondary substation, the electrical energy is transmitted to factories, business premises, office buildings, people's livelihood electricity and other equipment.

As shown in Figures 6 and 7, a group of elbow power generation modules 21 are provided at the bottom of the power plant area 2 and the elbow power generation module 21 is connected to one end of the connection part 141. As long as the seawater in the water storage area 14 can be injected into the elbow power generation module 21 to generate electricity, it is a technical solution that can be used in this application; the water level of the water storage area 14 is higher than the height of the elbow power generation module 21, and gravity is generated by the water level difference of the water storage area 14, so that the seawater stored in the water storage area 14 flows smoothly into the elbow power generation module 21, and the resistance of the seawater flowing into the elbow power generation module 21 is eliminated. In addition, the power plant area 2 is provided with an office area at the upper end of the elbow power generation module 21, and the office area must be higher than the seawater generator set 12.

As shown in Figures 6 and 7, the elbow power generation module 21 includes a plurality of elbows 211 that are interconnected and S-shaped, and a plurality of ocean current generators 212 that are arranged on the elbows 211 and used for secondary power generation; after the seawater enters the elbow 211, the seawater stored in the water storage area 14 flows in the elbow 211 due to gravity, and after the seawater flows through the ocean current generator 212, the coil in the ocean current generator 212 is excited to generate electrical energy, and the ocean current generator 212 is connected to the power grid 4 to output the generated electrical energy through the power grid 4.

After the speed change, the gear box converts the power to the ocean current generator 212, thereby achieving a double power generation effect.

For the convenience of subsequent maintenance, the bent tube power generation module 21 can be repaired and maintained through the maintenance pipeline 142 .

As shown in FIG9 , the drainage area 3 is connected to the end of the elbow power generation module 21, and after the seawater after power generation is discharged into the drainage area 3, the seawater is discharged into the ocean through a plurality of drainage pipelines 31. The drainage area 3 is set above the sea level, and the seawater after power generation is naturally discharged into the ocean for recycling through the drainage pipelines 31; if the drainage area 3 is set below the sea level, the seawater after power generation is discharged into the ocean for recycling through the drainage pipelines 31 by means of a pumping mechanism.
