Description

Technical Field

[0001] The present application relates to the technical field of dam structures, and specifically to a high-strength dam body impact-resistant structure. Background Art

[0002] In water conservancy project construction, dams, as crucial water conservancy facilities, perform multiple functions, including flood control, irrigation, and hydropower generation. However, traditional dam designs often focus on their basic function of retaining water, while lacking sufficient protection against water impact and maintaining the stability of the dam structure. Especially in conditions of rapid flow and high flow, the dam's front slope bears the immense impact of the water flow. This impact, often at high speed and high energy, can easily lead to damage, erosion, and even overall structural instability.

[0003] An existing patent (publication number: CN218346081U) discloses an anti-impact reinforcement structure for a dam body after heavy rainfall, comprising a concrete base, an anti-impact mechanism for the dam being provided on the upper side of the concrete base, the anti-impact mechanism comprising a fixing frame and a concrete pier, the fixing frame comprising a longitudinal main support frame and an anti-impact water retaining plate, and a reinforcing fixing connecting plate being provided on the lower side of the longitudinal main support frame. The utility model embeds the anti-impact water retaining plate in the front side of the concrete pier, and several long and thick screws pass through the anti-impact water retaining plate. The nuts are screwed onto the anti-impact water retaining plate to fix the anti-impact water retaining plate. When water waves impact, the water waves hitting the rows of anti-collision short columns and the rows of anti-collision reinforcement strips can disperse the water. The anti-impact water retaining plate can prevent the concrete pier from being damaged by the impact. At the same time, the anti-impact water retaining plate can be replaced to avoid the situation where it cannot be replaced after being damaged due to long-term use.

[0004] However, when the above structure is in use, the water flow and the base are prone to direct collision, and there is a lack of effective buffering mechanism to resist and absorb the impact force of the water flow, resulting in the impact force acting directly on the dam material, accelerating the aging and damage of the dam body. Utility Model Content

[0005] In response to the deficiencies of the prior art, the present application provides a high-strength dam body impact-resistant structure with advantages such as buffering and modular installation, solving the problems raised in the background technology.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a high-strength dam body impact-resistant structure, comprising a dam base, wherein a plurality of sleeves arranged at equal distances are fixedly embedded on one side of the dam base, a buffer rod being slidably inserted into the interior of each sleeve, a plurality of protective plates arranged at equal distances being provided on the right side of the dam base, wherein the left side of each protective plate is fixedly connected to two connecting seats, and each connecting seat is fixedly connected to the buffer rod adjacent thereto by bolts;

[0007] The top end of each protective plate is turned rightward.

[0008] Through the above scheme, by setting multiple groups of equidistantly arranged sleeves and slidingly plugged buffer rods on the dam foundation, combined with the flip-shaped protective plate design, the direct impact force of the water flow on the dam body is effectively dispersed and buffered. This structural design makes the water flow first contact the protective plate when contacting the dam body, and through the elastic deformation of the buffer rod and the energy absorption of the damper, the impact force is converted into elastic potential energy and thermal energy, thereby significantly reducing the actual impact effect of the water flow on the dam body and improving the impact resistance of the dam body. The impact-resistant structure adopts a modular design, and the various components are fixed by simple and reliable connection methods such as bolts and U-shaped connecting plates. It is not only easy to install, but also convenient for subsequent maintenance and replacement. In particular, the modular design of the protective plate enables it to be quickly located and replaced when damaged, reducing maintenance costs and time.

[0009] Furthermore, a plurality of linearly arranged dampers are fixedly embedded inside the dam foundation, and the output end of each damper is fixedly connected to the left side of the protective plate adjacent thereto by bolts.

[0010] Through the above solution and the provision of the damper, the purpose of energy absorption can be achieved.

[0011] Furthermore, a spring is installed inside each sleeve.

[0012] Through the above solution, the purpose of buffering and energy absorption can be achieved by setting the spring and cooperating with the damper.

[0013] Furthermore, a connection groove is provided on one side of each of the protective plates.

[0014] Through the above solution, by providing the connection groove, it is possible to facilitate the connection of two protective plates that are close to each other.

[0015] Furthermore, a plurality of U-shaped connecting plates are inserted into the interior of every two adjacent connecting grooves, and a limiting screw is installed inside each U-shaped connecting plate.

[0016] Through the above solution, the purpose of connecting the protective plate can be achieved by setting the U-shaped connecting plate and the limiting threaded rod.

[0017] Furthermore, each of the protective plates is made of corrosion-resistant material.

[0018] According to the above solution, the overall service life can be increased by setting the protective plate to be corrosion-resistant material.

[0019] Furthermore, the bottom of each protective plate contacts the bottom end of the dam foundation, and the top of each protective plate is slidably plugged into the dam foundation.

[0020] Through the above solution, the bottom of the protective plate contacts the bottom end of the dam foundation and the top of the protective plate is slidably connected with the dam foundation, which can ensure the stable movement of the protective plate after being subjected to force.

[0021] Furthermore, a plurality of protrusions are fixedly connected inside each of the connecting grooves.

[0022] Through the above solution, by providing the protrusions, it is possible to block the U-shaped connecting plate and prevent it from sliding downward under the action of gravity.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0024] This high-strength dam body impact-resistant structure effectively disperses and buffers the direct impact force of water flow on the dam body by arranging multiple groups of equidistantly arranged sleeves and slidingly inserted buffer rods on the dam foundation, and cooperating with a flip-shaped protective plate design. This structural design allows the water flow to first contact the protective plate when contacting the dam body, and through the elastic deformation of the buffer rod and the energy absorption of the damper, the impact force is converted into elastic potential energy and thermal energy, thereby significantly reducing the actual impact effect of the water flow on the dam body and improving the impact resistance of the dam body. The impact-resistant structure adopts a modular design, and the various components are fixed by simple and reliable connection methods such as bolts and U-shaped connecting plates. It is not only easy to install, but also convenient for subsequent maintenance and replacement. In particular, the modular design of the protective plate enables it to be quickly located and replaced when damaged, reducing maintenance costs and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See also Figure 1 、 Figure 2 and Figure 4 The top of each protective plate 4 is flipped to the right. By flipping the top of the protective plate 4 to the right, it can prevent the tide from hitting the road surface along the protective plate 4 under the action of inertia. A plurality of dampers 6 arranged in a straight line are fixedly embedded in the interior of the dam foundation 1. The output end of each damper 6 is fixedly connected to the left side of the protective plate 4 close to it by bolts. The setting of the damper 6 can achieve the purpose of energy absorption. A spring 7 is installed inside each sleeve 2. Through the setting of the spring 7 and the cooperation with the damper 6, the purpose of buffering and energy absorption can be achieved.

[0034] See also Figure 1 、 Figure 2 and Figure 3 A connecting groove 8 is provided on one side of each protective plate 4. Through the setting of the connecting groove 8, two protective plates 4 close to each other can be easily connected. A plurality of U-shaped connecting plates 9 are inserted into the inside of each two adjacent connecting grooves 8. A limiting screw 10 is installed inside each U-shaped connecting plate 9. Through the setting of the U-shaped connecting plate 9 and the limiting threaded rod, the connection purpose of the protective plate 4 can be achieved.

[0035] See also Figure 1 、 Figure 2 and Figure 3Each protective plate 4 is made of corrosion-resistant material. By making the protective plate 4 into corrosion-resistant material, the overall service life can be improved. The bottom of each protective plate 4 contacts the bottom end of the dam base 1, and the top of each protective plate 4 is slidably plugged into the dam base 1. By making the bottom of the protective plate 4 contact the bottom end of the dam base 1 and the top of the protective plate 4 is slidably plugged into the dam base 1, the stable movement of the protective plate 4 after being subjected to force can be ensured. A plurality of protrusions 11 are fixedly connected to the interior of each connecting groove 8. Through the setting of the protrusion 11, the U-shaped connecting plate can be blocked to prevent it from sliding downward under the action of gravity.

[0036] A high-strength dam body impact-resistant structure in this embodiment effectively disperses and buffers the direct impact force of the water flow on the dam body by arranging multiple groups of equidistantly arranged sleeves 2 and slidingly inserted buffer rods 3 on the dam foundation 1, and cooperating with the flip-shaped protective plate 4 design. This structural design allows the water flow to first contact the protective plate 4 when contacting the dam body, and through the elastic deformation of the buffer rod 3 and the energy absorption of the damper 6, the impact force is converted into elastic potential energy and heat energy, thereby significantly reducing the actual impact effect of the water flow on the dam body and improving the impact resistance of the dam body. The impact-resistant structure adopts a modular design, and the various components are fixed by simple and reliable connection methods such as bolts and U-shaped connecting plates 9. It is not only easy to install, but also convenient for subsequent maintenance and replacement. In particular, the modular design of the protective plate 4 enables it to be quickly located and replaced when damaged, reducing maintenance costs and time.

[0037] The working principle of the above embodiment is as follows: when the water flow is stable or at a small flow rate, the protective plate 4 is in a normal position, its top end is flipped to the right, the bottom end is in close contact with the dam base 1, and the top end is connected to the dam base 1 by a sliding plug-in method to maintain the stability of the overall structure. At this time, the buffer rod 3 in the sleeve 2 is in a naturally extended state, the spring 7 is in an uncompressed state, and the damper 6 is also in a standby state. When encountering turbulent or high-flow water flow, the water flow first contacts the protective plate 4. Since the protective plate 4 is designed to be flipped, the water flow is guided to the right under the action of inertia, avoiding direct hitting the dam body or the road surface. At this time, the protective plate 4 is subjected to the impact force of the water flow, which is transmitted to the buffer rod 3 through the connecting seat 5. As the protective plate 4 is subjected to the force, the buffer rod 3 begins to slide inward in the sleeve 2, compressing the internal spring 7. The compression process of the spring 7 absorbs part of the impact energy. , and converts it into elastic potential energy and stores it. In this process, the sliding of the buffer rod 3 and the compression of the spring 7 jointly play a preliminary buffering role. At the same time, the damper 6 fixedly connected to the left side of the protective plate 4 also starts to work. When the output end of the damper 6 is subjected to tension or pressure, the damping medium inside it will undergo viscous flow or shear deformation, thereby consuming a large amount of impact energy and converting it into heat energy and dissipating it. This process further weakens the impact force transmitted to the dam body. During long-term use, if the protective plate 4 needs to be replaced due to wear or damage, it can be easily achieved by removing the bolts and the limit screw 10 on the U-shaped connecting plate 9. The new protective plate 4 is also easy to install. You only need to re-fix the connecting seat 5 and insert the U-shaped connecting plate 9. There is no need to carry out large-scale dismantling and modification of the entire structure, which greatly reduces maintenance costs and time.
