The specific modes of use of the three power generation applications are summarized as follows:

example 1: application of double-reservoir unidirectional tidal power generation cloth

As shown in fig. 11, in this embodiment, the first reservoir 85 and the second reservoir 86 are constructed by the reservoir dam 8, a unit dam 83 is arranged between the first reservoir 85 and the second reservoir 86, a plurality of sets of generating units 84 are arranged on the unit dam 83, and the reservoir gate I81 and the reservoir gate II82 are arranged on both the first reservoir 85 and the second reservoir 86, which can be matched with an external control system. In operation, the level of the second reservoir 86 is brought to a minimum level when the seawater has faded to a minimum level. When the seawater rises to the highest water level in the day, the first reservoir 85 is filled with water, and water is discharged to the second reservoir 86 and drives the generator set 84 to generate power while the first reservoir 85 is filled with water.

When the seawater is ebb of tide to be lower than the water surface of the second reservoir 86, the second reservoir 86 starts to discharge water into the sea until the water surface is lowest, and the system is shut down.

When the seawater rises to a level higher than the first reservoir 85, water is added to the first reservoir 85 and discharged to the second reservoir 86, and the generator set 84 is driven to operate and generate electricity. Thereby beginning to cycle uninterrupted power generation.

Example 2: single-reservoir bidirectional tidal power generation

As shown in fig. 12, the embodiment includes a sea-facing reservoir 87, a sea-facing reservoir gate 88 is disposed on the reservoir dam 8 around the sea-facing reservoir 87, a generator set 84 is disposed on the generator set dam 83, and the operation process is as follows in cooperation with an external control system:

flood tide power generation:

firstly, when the seawater is ebb to the lowest, the sea reservoir gate 88 is opened, and the sea reservoir 87 water is discharged into the sea as much as possible until the lowest water level is reached.

When the sea water rises to a certain water level difference with the sea-facing reservoir 87 and can drive the generator set 84 to rotate and generate electricity, the sea-facing reservoir gate 88 is opened to discharge water to the sea-facing reservoir 87 for electricity generation, and the generator set 84 is stopped to operate when the sea water level and the sea-facing reservoir 87 water level are close to the high tide level in the same day and the difference between the internal water level and the external water level is small to prevent the generator set 84 from being driven to generate electricity after the water is discharged for electricity generation. When the tide reaches the water level difference after the tide fades and can generate electricity, the generating equipment automatically reverses to fade the tide to generate electricity.

Secondly, the tide is removed to generate electricity:

when the tide is drawn back to the level of the sea water which is lower than the water level of the reservoir 87 near the sea and the water level difference can drive the generator set 84 to generate electricity, the generating equipment automatically rotates reversely to draw the tide to generate electricity until the sea water starts to rise and is level with the reservoir water level, and the electricity is suspended. When the sea water is higher than the level of the sea-facing reservoir 87 and can be generated by the generator set 84, the sea water is automatically converted into flood tide power generation, and the cycle is carried out.
