Detailed implementation manners

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Embodiment 1: This embodiment provides a water retaining structure for reservoir reinforcement and risk elimination. Refer to Figure 1-7 , which includes a U-shaped plate 1. A horizontally distributed cross plate 11 is fixedly arranged in the upper middle part of the opening of the U-shaped plate 1. A pair of symmetrically distributed elliptical sliding holes are opened on both side walls of the U-shaped plate 1. The back surface of the U-shaped plate 1 is successively provided with a first water baffle 101, a second water baffle 102, and a third water baffle 103 arranged side by side from top to bottom. The three water baffles form a protection system, greatly enhancing the water retaining capacity of the reservoir dam. Each water baffle can bear a part of the water pressure and jointly resist the impact of the water flow; Sealing grooves are opened on both side surfaces of the first water baffle 101, the second water baffle 102, and the third water baffle 103. A vertically penetrating sealing strip 104 is clamped in the sealing grooves on the same side. The three water baffles support each other during operation, enhancing the stability of the overall structure. The water pressure received by the upper water baffle can be partially transmitted to the lower water baffle, dispersing the pressure and reducing the risk of damage to a single water baffle due to excessive stress; A fixed shaft 2 penetrating horizontally is rotatably inserted at the open top of the U-shaped plate 1. A pair of symmetrically distributed first gears 201 are fixedly arranged at both ends of the fixed shaft 2. A first L-shaped plate 202 is fixedly arranged on each first gear 201.

Each third L-shaped plate 213 is threadedly locked with the third water baffle 103 through a pair of third bolts; Since there are multiple water baffles, they can be inspected and maintained layer by layer. When a problem is found with a certain water baffle, it can be repaired or replaced individually without affecting the normal operation of other water baffles, reducing the maintenance cost and difficulty.
