Hydraulic safety guardrail for hydropower station

The invention discloses a hydraulic safety guardrail for a hydropower station, and belongs to the technical field of hydraulic safety devices. Comprising stand columns, an inner buffer plate, an outer buffer plate, a bottom buffer plate, a base, compression springs, a top beam and a bag net. The base is fixed to the ground, the bottom ends of the stand columns are fixedly connected with the base, the top ends of the stand columns are fixedly connected with the top beam, and the net is arranged between the adjacent stand columns. The upper ends of the inner buffer plate and the outer buffer plate are fixedly connected with the top beam, and the inner buffer plate is located between the outer buffer plate and the stand column. One end of the bottom buffer plate is hinged to the bottom of the stand column, the lower side of the other end of the bottom buffer plate is connected with the ground through a compression spring, and the compression spring is in a compression energy-storage state while the upper side is
