The invention discloses an anchoring system of a floating type photovoltaic power generation platform, and the anchoring system comprises two buoys, a platform and a photovoltaic panel; the platform is fixed between the two buoys, a support plate is fixed on the upper side wall of each buoy, a mounting plate is fixed at the upper ends of the two support plates, and the photovoltaic panel is mounted on the mounting plate. The construction method of the anchoring system of the floating type photovoltaic power generation platform comprises the following steps that S1, the buoy and the platform are fixed, and the photovoltaic panel is placed on the mounting plate to be fixed; S2, the end of the rotating plate is fixed to the anchor rope, the buoy is placed on the water surface, and the anchor block sinks into the water surface to be fixed. The system has the advantages that the position of the upper end of the anchor rope is adjusted to ensure that the anchor rope is always in a tightened state, on one hand, the buoy and the platform are prevented from moving when the water level is too low, on the other hand, the buoy and the platform are prevented from being affected by large resistance when the water level is too high, and the photovoltaic efficiency is ensured by regularly cleaning the photovoltaic panel.
