The invention belongs to the technical field of power stations, and particularly relates to a tidal current energy power station. The tidal current energy power station comprises a plurality of generator sets arranged at intervals. Each generator set comprises a connecting rod. The connecting rods are arranged on a plurality of fixed piles arranged at intervals and can rotate on the fixed piles. A plurality of umbrella-shaped power generating mechanisms are arranged on the connecting rods at intervals. One end of the connecting rod is connected with a generator by a speed-up machine. The umbrella-shaped power generating mechanisms can fold and unfold. In an unfolding state, the umbrella-shaped power generating mechanisms can drive the connecting rods to rotate together under the action of tidal current so as to drive a generator rotor to rotate so as to generate electricity. According to the invention, paddles rotate under the action of thrust of tidal current to drive the connecting rods to rotate so as to further drive the generator to work for generating electricity, natural clean energy is utilized, and tidal current is converted into electric energy, thus the process is clean and environment-friendly; and the power station is low in manufacture cost, convenient for dismounting and mounting, simple in structure and easy to maintain, and takes effect quickly.
