The invention discloses a ship lock floating type bollard. The ship lock floating type bollard comprises a float bowl sliding on a track pulley, a ship lock chamber located on the outer side of the track pulley, a bollard body installed on the float bowl, a first power generation part wrapping the outer side of the bollard body, a second power generation part arranged inside the float bowl, and a storage battery for storing power generated by the first power generation part and the second power generation part through a matched circuit. Power is generated through fluctuation of the water level generated during working of a ship lock and berthing force and mooring force of a ship, and the ship lock floating type bollard also has the mooring function. Kinetic energy in the vertical and horizontal directions is converted into power through the fluctuation of the water level and the kinetic energy of the ship, and the design concepts of energy conservation, emission reduction and low carbon are achieved.
