the first pipeline is provided with a first valve, and the second pipeline is provided with a second valve;
a third valve is arranged between the first valve and the second valve;
the first valve, the second valve and the third valve are all closed, so that seawater can be prevented from entering the equipment installation cabin;
and a second one-way valve is arranged between the first valve and the second water outlet, and a first one-way valve is arranged between the second valve and the first water outlet.
Compared with the prior art, the invention has the beneficial effects that: when tide rises, seawater enters from the first water inlet and pushes the first hydraulic generator to rotate through bell mouth pressurization and then goes out from the second water outlet, when tide falls, seawater enters from the second water inlet and pushes the second hydraulic generator to rotate through bell mouth pressurization and then goes out from the first water outlet, a second one-way valve is arranged between the first valve and the second water outlet, a first one-way valve is arranged between the second valve and the first water outlet, so that the first water outlet and the second water outlet cannot be mutually communicated, and the first water outlet and the second water outlet can only discharge water and cannot feed water. The floating body can be used as a floating pier.
