Detailed Description
The invention is further illustrated by the following figures and examples, which are not to be construed as limiting the invention.
Examples are given. The flood discharge culvert of the pumped storage power station is formed as shown in figures 1 to 5 and comprises a culvert body 1, wherein one end of the culvert body 1 is provided with a water inlet 2, the other end of the culvert body 1 is provided with a water outlet 3, and a splayed flaring structure is arranged between the water inlet 2 and the water outlet 3; a flood discharge gate 4 is arranged at the water inlet 2; a lifting driving mechanism 5 is arranged above the flood discharge gate 4; the inner bottom surface of the culvert body 1 is provided with a group of lifting step structures 6.
The lifting type step structure 6 comprises a waterproof lifting hydraulic cylinder 601, a lifting rod 602 is arranged at the output end of the waterproof lifting hydraulic cylinder 601, a bottom plate 603 is arranged at the upper end of the lifting rod 602, an arc-shaped protrusion 604 is arranged on the upper surface of the bottom plate 603, and an energy dissipation bump 605 is arranged on the arc-shaped protrusion 604.
A waterproof rolling shutter assembly is provided between the adjacent bottom plates 603.
The outside of drainage floodgate 4 still is equipped with surface of water rubbish clearance subassembly 7.
The water surface garbage cleaning assembly 7 comprises a lifting frame 701 arranged on the outer side of the flood discharge gate 4, a movable pushing plate 702 is arranged in the lifting frame 701, and a screen 703 is further arranged on the side face of the bottom of the movable pushing plate 702.
The water level monitoring device 704 is further arranged below the lifting frame 701, lifting supports 707 are arranged at the tops of two ends of the outer side of the flood discharge gate 4, lifting hydraulic rods 705 are arranged on the lifting supports 707, and the bottoms of the lifting hydraulic rods 705 are fixed to the lifting frame 701.
