Description

Technical Field

[0001] The present application relates to the technical field of dams, and in particular to an anti-tilt dam structure. Background Art

[0002] A dam is a water-retaining structure that intercepts water flow in rivers and channels to raise water levels or regulate flow. It can form a reservoir, raise water levels, regulate runoff, and concentrate water head. It is used for flood control, water supply, irrigation, hydroelectric power generation, and improved navigation. River regulation structures that adjust river flow and protect the bank bed are also called dams, such as spur dams, downstream dams, and submerged dams.

[0003] The side of the dam body close to the water flow is often impacted by the water flow. When the water flow is large, the accumulated water flow will have a greater impact on the dam, reducing the stability of the dam. Utility Model Content

[0004] In order to improve the stability of the dam, the present application provides an anti-tilt dam structure.

[0005] The anti-tilt dam structure provided in this application adopts the following technical solution:

[0006] An anti-tilt dam structure comprises a dam body, a baffle being slidably mounted on one side of the dam body close to the water surface, the sliding direction of the baffle being perpendicular to the side of the dam body close to the baffle, the baffle being flush with the side of the dam body close to the baffle, a plurality of baffles being arranged along the extension direction of the dam body, and an elastic component being arranged between the baffle and the dam body for providing a buffer for the sliding of the baffle.

The elastic component can provide resistance to the sliding of the baffle, thereby slowing down the flow rate of the water flow and reducing the scouring of the dam body by the water flow, thereby achieving the anti-tilting of the dam body; when the water flow is small, the elastic component can drive the baffle to slide and move away from the dam body, thereby returning the baffle to its original position, making it easier for the baffle to slow down the impact of the next large wave of water flow on the dam body, thereby improving the stability of the dam as a whole.

[0008] Optionally, the elastic component includes an elastic telescopic rod, which is arranged one-to-one corresponding to the baffle, one end of the elastic telescopic rod is connected to the dam body, and the other end is connected to the baffle, and the elastic telescopic rod is perpendicular to the corresponding baffle.

[0012] Optionally, the elastic telescopic rod also includes a spring, which is located in the support tube. The spring is coaxial with the support tube, and one end of the spring is against one end of the support rod close to the support tube, and the other end is against the bottom wall of the support tube.

[0013] By adopting the above technical solution, when the baffle slides toward the dam body, the support rod slides into the support tube, causing the spring to compress and deform. The spring can increase the resistance to the support rod sliding into the support tube, thereby providing resistance to the baffle sliding toward the dam body.

[0014] Optionally, a limiting groove is provided on the inner side wall of the support tube along the length direction of the support tube, and a limiting block is provided on the support rod. The limiting block is located in the limiting groove, and the limiting block is slidably adapted to the limiting groove.

[0015] By adopting the above technical solution, the limit groove and the limit block cooperate with each other to guide the sliding in and out of the support rod, and to limit the relative rotation between the support rod and the support tube, thereby reducing the rotation of the baffle along the axis of the support tube.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When the water flow is large and impacts the dam body, the water flow contacts the baffle, which can drive the baffle to slide and approach the dam body. The elastic component can provide resistance to the sliding of the baffle, thereby slowing down the flow rate of the water flow and reducing the scouring of the dam body by the water flow, thereby preventing the dam body from tilting. When the water flow is small, the elastic component can drive the baffle to slide and move away from the dam body, so that the baffle returns to its original position, making it easier for the baffle to slow down the impact of the next large wave of water flow on the dam body, thereby improving the stability of the dam as a whole.

[0024] 2. When the baffle slides toward the dam body, the support rod slides into the support tube, causing the spring to compress and deform. The spring can increase the resistance to the support rod sliding into the support tube, thereby providing resistance to the baffle sliding toward the dam body;

[0025] 3. The baffle slides and approaches the dam body, so that when the support rod is immersed in the support tube, the support plate presses against the dam body, thereby increasing the contact area with the dam body through the support plate and reducing the pressure during the collision between the support tube and the dam body.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses an anti-tilt dam structure. Figure 1 and Figure 2 The anti-tilting dam structure includes a dam body 1, a baffle 2 is slidably installed on one side of the dam body 1 close to the water surface, the sliding direction of the baffle 2 is perpendicular to the side of the dam body 1 close to the baffle 2, the baffle 2 is flush with the side of the dam body 1 close to the baffle 2, a plurality of baffles 2 are arranged along the extension direction of the dam body 1, and an elastic component 3 for providing buffering for the sliding of the baffle 2 is arranged between the baffle 2 and the dam body 1. When the water flow is large and impacts the dam body 1, the water flow contacts the baffle 2, which can drive the baffle 2 to slide and approach the dam body 1, and the elastic component 3 can provide resistance to the sliding of the baffle 2, so that the flow rate of the water flow is slowed down, and the scouring of the dam body 1 by the water flow is reduced, so as to achieve the anti-tilting of the dam body 1; when the water flow is small, the elastic component 3 can drive the baffle 2 to slide and move away from the dam body 1, so that the baffle 2 returns to its original position, so that the baffle 2 can slow down the impact of the next large water flow on the dam body 1, and the stability of the dam is improved as a whole.

[0033] The side of the dam body 1 close to the water surface is an inclined surface, and a water hole 21 is provided on the baffle plate 2. There are multiple water holes 21. When the water flow is relatively gentle, the water can flow through the water holes 21. A protective plate 4 is also provided on the side of the dam body 1 close to the water surface. An anchor rod 5 is provided between the protective plate 4 and the dam body 1. One end of the anchor rod 5 is cast in the dam body 1 and the other end is welded to the protective plate 4, which improves the stability of the protective plate 4 on the dam body 1; the protective plate 4 can be a corrosion-resistant metal plate, thereby extending the protection time of the protective plate 4 and reducing the scouring of the dam body 1 by the water flow. There are multiple protective plates 4 on the dam body 1, and multiple protective plates 4 are provided along the extension direction of the dam body 1, and there are gaps between adjacent protective plates 4.

[0034] Reference Figure 2 and Figure 3 The elastic component 3 includes an elastic telescopic rod, which is perpendicular to the baffle 2. The elastic telescopic rod is arranged one by one corresponding to the baffle 2. One end of the elastic telescopic rod is connected to the dam body 1, and the other end is connected to the baffle 2. The elastic telescopic rod is perpendicular to the corresponding baffle 2. The elastic telescopic rod can guide the sliding of the baffle 2, improve the sliding stability of the baffle 2, and can also provide buffering for the sliding of the baffle 2.

[0035] Furthermore, the elastic telescopic rod includes a support rod 31, a support tube 32 and a spring 33. The support tube 32 is a cylinder, the support rod 31 is a round rod, the support tube 32 is coaxial with the support rod 31, the end of the support tube 32 close to the support rod 31 has an opening, and the support rod 31 is coaxially slidably installed in the support tube 32. The spring 33 is located in the support tube 32, the spring 33 is coaxial with the support tube 32, and one end of the spring 33 abuts against one end of the support rod 31 close to the support tube 32, and the other end abuts against the bottom wall of the support tube 32.

[0036] When the baffle 2 slides and approaches or moves away from the dam body 1, the support rod 31 slides into or out of the support tube 32, realizing the extension and retraction of the elastic telescopic rod. When the baffle 2 slides toward the dam body 1, the support rod 31 slides into the support tube 32, causing the spring 33 to be compressed and deformed. The spring 33 can increase the resistance to the support rod 31 sliding into the support tube 32, thereby providing resistance to the baffle 2 sliding toward the dam body 1.

[0037] In order to reduce the relative rotation between the support tube 32 and the support rod 31, a limiting groove 321 is provided on the inner side wall of the support tube 32 along the length direction of the support tube 32, and a limiting block 311 is provided on the support rod 31. The limiting block 311 is located in the limiting groove 321, and the limiting block 311 is slidably adapted to the limiting groove 321. When the support rod 31 slides in the support tube 32, the limiting block 311 can slide in the limiting groove 321, and can guide the sliding of the support rod 31. The limiting block 311 and the limiting groove 321 cooperate to limit the relative rotation between the support rod 31 and the support tube 32, thereby reducing the rotation of the baffle 2 and improving the sliding stability of the baffle 2.

[0038] Reference Figure 2 and Figure 3 One end of the support tube 32 away from the support rod 31 is welded to the side of the baffle 2 close to the dam body 1, and the other end of the support rod 31 away from the support tube 32 is cast in the dam body 1. The end of the support tube 32 close to the support rod 31 is welded with a support plate 6, and the support plate 6 is parallel to the baffle 2, and the surface area of ​​the baffle 2 is larger than the cross-sectional area of ​​the support tube 32. When the baffle 2 slides and approaches the dam body 1 and the support plate 6 presses against the dam body 1, the contact area with the dam body 1 is increased by the support plate 6, thereby reducing the pressure during the collision between the support tube 32 and the dam body 1.

[0039] A flexible pad 7 is bonded to the side of the baffle 2 close to the dam body 1, and the flexible pad 7 can reduce the damage of the baffle 2 when it hits. An oblique connecting rod 8 is also provided between the support tube 32 and the baffle 2, one end of the oblique connecting rod 8 is welded to the baffle 2, and the other end is welded to the outer wall of the support tube 32, the axis of the oblique connecting rod 8 intersects with the axis of the support tube 32, and four oblique connecting rods 8 are arranged around the circumference of the support tube 32, and the oblique connecting rods 8 improve the stability of the connection between the baffle 2 and the support tube 32.

[0040] The implementation principle of the anti-tilt dam structure of the embodiment of the present application is as follows: when the water flow is large and impacts the dam body 1, the water flow contacts the baffle 2, which can drive the baffle 2 to slide and approach the dam body 1. The elastic component 3 can provide resistance to the sliding of the baffle 2, thereby slowing down the flow rate of the water flow and reducing the scouring of the dam body 1 by the water flow, thereby achieving the anti-tilt of the dam body 1; when the water flow is small, the elastic component 3 can drive the baffle 2 to slide and move away from the dam body 1, thereby allowing the baffle 2 to return to its original position, making it easier for the baffle 2 to slow down the impact of the next large wave of water flow on the dam body 1, thereby improving the stability of the dam as a whole.
