Description

Technical Field

[0001] The present invention relates to the technical field of reservoir reinforcement, and in particular to a reservoir hazard removal reinforcement water retaining structure and a water retaining method thereof. Background Art

[0002] After long-term use, the dam of a reservoir will show some signs of aging and corrosion. Under the continuous erosion of rainwater and river water, pits and cracks will appear on the water-facing side of the dam, which may even lead to a dam breach in severe cases. In order to ensure the stability of the dam, a reinforcement structure is needed to reinforce the dam externally.

[0003] A Chinese utility model patent discloses a water retaining structure for reservoir hazard removal and reinforcement (publication number: CN221000846U), which includes: a water retaining plate, on which a box body is fixedly installed; a cross plate, which is arranged inside the box body; a hinge block, which is fixedly installed on one side of the water retaining plate; a first bolt, which is rotatably installed on the cross plate; and two second bolts, which are both rotatably installed on the cross plate.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] Example 1: This example provides a reservoir risk removal and reinforcement water retaining structure, see Figure 1-7 , including a U-shaped plate 1, a transversely distributed horizontal plate 11 is fixed in the middle and upper part of the opening of the U-shaped plate 1, a pair of symmetrically distributed elliptical sliding holes are opened on the two side walls of the U-shaped plate 1, and a first water retaining plate 101, a second water retaining plate 102, and a third water retaining plate 103 are installed in sequence on the back of the U-shaped plate 1 from top to bottom. The three water retaining plates form a protection system, which greatly enhances the water retaining capacity of the reservoir dam. Each water retaining plate can bear part of the water pressure and jointly resist the impact of the water flow;

[0046] The first water baffle 101, the second water baffle 102, and the third water baffle 103 are each provided with a sealing groove on both sides. A vertically penetrating sealing strip 104 is engaged in the sealing groove on the same side. The three water baffles support each other during operation, thereby enhancing the stability of the overall structure. The water pressure on the upper water baffle can be partially transferred to the lower water baffle, dispersing the pressure and reducing the risk of damage to a single water baffle due to excessive force.

[0047] A fixed shaft 2 is rotatably inserted into the open top of the U-shaped plate 1 and is distributed transversely therethrough. A pair of symmetrically distributed first gears 201 are fixed to both ends of the fixed shaft 2. A first L-shaped plate 202 is fixed to each first gear 201. Each first L-shaped plate 202 is threadedly locked to the first water retaining plate 101 by a pair of first bolts.

[0048] A first elliptical slider 205 is slidably engaged in the middle of each elliptical sliding hole, and a first connecting shaft is rotatably inserted into the top of the outer side of each first elliptical slider 205. The outer end of each first connecting shaft is sleeved with a concentrically fixed third gear 206, and each third gear 206 is fixed with a second L-shaped plate 207. Each second L-shaped plate 207 is threadedly locked with the second water retaining plate 102 by a pair of second bolts.

A fourth connecting rod 212 is fixed to the outer end of each second connecting shaft, and a third L-shaped plate 213 is fixed to the bottom end of each fourth connecting rod 212. Each third L-shaped plate 213 is threadedly locked with the third water baffle 103 by a pair of third bolts.

[0050] Since there are multiple water baffles, they can be inspected and maintained in layers. When a problem is found in a water baffle, it can be repaired or replaced individually without affecting the normal operation of other water baffles, reducing maintenance costs and difficulty.

[0051] Example 2: Based on Example 1, this example also includes the following contents:

[0052] like Figure 4 and Figure 7 As shown, a third connecting shaft is rotatably inserted at the top of both sides of the U-shaped plate 1.

The third gear 206 can mesh and drive the fourth gear 209, the third connecting rod 210, and the fourth connecting shaft to rotate downward.

[0055] A third connecting rod 210 is fixed on each fourth gear 209, and the bottom end of each third connecting rod 210 is movably hinged to the top end of the adjacent fourth connecting rod 212.

A pair of first swing arms 14 are fixedly provided on both sides of the horizontal shaft 13. A second swing arm 15 is hingedly provided at the middle of each fixed ear seat 12. The first swing arm 14 and the second swing arm 15 on the same side are distributed in parallel. Since the first swing arm 14 and the second swing arm 15 on the same side are in a parallel hinged state, they can synchronously drive the pair of second swing arms 15 to flip downward.
