[0069] Based on the above specific implementation, the working process of the tidal current power generation device in this embodiment is as follows:

[0070] S1. Install in place. Install the tidal current clustering equipment on the pile foundation, and the tidal current generator set is located inside the tidal current clustering equipment.

[0071] S2. Opening size control and adjustment. According to the tidal current direction and size, determine the size relationship between the first opening 11 and the second opening 12 of the tidal current power generation equipment, refer to Figure 5 , Figure 6(The two generator sets arranged back to back are not shown in the figure. Their positions are referenced to the position of the mounting hole 101 of the base plate 10.

Taking into account the tidal flow loss and the fact that the generator set is not located at the first opening 11 or the second opening 12, it is actually required that S1 / S2>V3 / V1 (taking the generator set being located near the second opening 12 and the flow velocity of the first opening 11 being the tidal velocity as an example).

[0072] When the incoming tide direction Figure 5 When the direction of the middle C is consistent, the side plate 30 is driven to slide along the slide rail 401, so that the second opening 12 is located near the generator set. Through the cooperation of the strip 40 and the side plate 30, the tidal velocity at the generator set is adjusted; when the dissipation direction is consistent with Figure 6 When the middle D directions are consistent, the side vertical plate 30 is driven to slide along the slide rail 401 so that the first opening 11 is located near the generator set. Through the cooperation between the strip 40 and the side vertical plate 30, the tidal current speed at the generator set is adjusted.

[0073] S3, cyclically regulating the opening size during incoming and outgoing tides. According to the incoming and outgoing tides, the relative sizes of the first opening 11 and the second opening 12 are cyclically regulated according to S2 to achieve bidirectional tidal convergence, change the tidal flow velocity near the generator set, and meet the bidirectional power generation demand.
