The caisson energy storage power generation system comprises a cylindrical caisson, the caisson is embedded into a seabed according to the suction anchor principle, and water is fed and discharged through a water pump/water turbine by means of water head potential energy for energy storage and power generation. The cylindrical caisson bottom suction anchor is composed of a plurality of anchor barrels, an annular pipeline, a main pipeline and a check valve, and each anchor barrel is communicated with the main pipeline through the check valve and the annular pipeline to form a suction anchor system which is embedded into underwater sludge. If a certain anchor cylinder leaks, the stability of the suction anchor system is not caused. Due to the water permeability of seabed sediment, water is sucked out of a suction anchor system, the original internal and external pressure difference of the suction anchor system is damaged, and the suction anchor loses efficacy. The cylindrical caisson tends to move up and down u
