Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, and in particular to a water-retaining weir for water conservancy construction. Background Technology

[0002] During the construction of water conservancy projects, weirs, as temporary water-retaining structures, have the core function of blocking water flow and creating a dry construction environment, which is crucial to ensuring the smooth progress of the main project. However, the application of existing weirs under complex hydrogeological conditions still has many technical challenges, making it difficult to balance seepage prevention performance, impact resistance, and structural stability.

[0003] Traditional weirs often suffer from frequent water leakage problems due to insufficient sealing at the connection between the weir body and additional structures, or the inability of the impermeable layer to adapt to foundation deformation. Especially in highly permeable strata such as sand and gravel, conventional seepage prevention measures are prone to cracking and failure, leading to risks such as pit flooding and slope instability. This not only delays construction progress but also increases maintenance costs. In the field of impact resistance and erosion prevention, direct impact of water flow on the weir's slope and toe can easily cause structural erosion. Existing weirs mostly rely on rigid revetments to resist impact, lacking flexible buffering mechanisms. Instantaneous water flow loads can easily lead to stress concentration, causing revetment damage or fatigue damage to the weir structure. Simultaneously, debris in the water flow can easily clog drainage structures, further weakening the load-bearing capacity of the weir. Utility Model Content

[0013] (III) Beneficial Effects

[0014] This utility model provides a water-retaining weir for hydraulic construction. It has the following beneficial effects:

[0015] 1. The buffer system, consisting of a protective plate, movable frame, sliding seat, guide rod, and buffer spring, has excellent impact resistance. When water flows into the protective plate, the impact force is transmitted to the sliding seat through the fixed seat and movable frame. The guide rod precisely limits the sliding trajectory of the sliding seat to prevent deviation and shaking. The sliding seat squeezes the buffer spring, and the spring absorbs the impact kinetic energy through elastic deformation, reducing the peak load transmitted to the main body of the weir. The spring reset can drive the sliding seat to return to its initial position to achieve repeated buffering, which greatly reduces the damage of water flow impact to the weir and extends its service life.

[0016] 2. Through the coordinated design of the weir frame, sealing brick layer, permeable holes, and S-shaped barrier plate, efficient diversion, pressure reduction, and seepage prevention are achieved. The S-shaped barrier plate can change the direction of water flow and increase resistance to slow down the flow velocity, reduce the scouring force of water flow on the main body of the weir, and intercept debris in the water to prevent blockage. The permeable holes can divert part of the water flow, adjust the water level difference on both sides of the weir, and reduce lateral pressure. The sealing brick layer enhances the connection and sealing between the weir frame and the main body of the weir, effectively preventing water leakage and ensuring the seepage prevention performance and structural stability of the weir.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Reference Figures 1 to 5As shown, this utility model provides a technical solution: a water-retaining weir for hydraulic construction, including a water-retaining weir body 1, a weir frame 3 provided on the inclined slope of the water-retaining weir body 1, a fixed frame 6 provided at the lower end of the weir frame 3, the fixed frame 6 being fixedly connected to the lower end of the water-retaining weir body 1 by bolts, and a connecting plate 7 fixedly connected to one side of the fixed frame 6, a sliding rod 8 fixedly connected to the surface of the connecting plate 7, a sliding seat 9 sleeved on the surface of the sliding rod 8, a movable frame 10 rotatably connected to the surface of the sliding seat 9, a fixed seat 11 rotatably connected to one end of the movable frame 10, and a protective plate 12 fixedly connected to one side of the fixed seat 11, the water-retaining weir frame 3 provided on the inclined slope of the water-retaining weir body 1... In conjunction with the lower fixed frame 6, bolts securely connect the fixed frame 6 to the main body 1 of the weir, ensuring the overall structural reliability. A connecting plate 7 on one side of the fixed frame 6 fixes a sliding rod 8. A sliding seat 9, fitted onto the surface of the sliding rod 8, can slide along the rod and is rotatably connected to the movable frame 10. The other end of the movable frame 10 is connected to the protective plate 12 via a fixed seat 11, forming an adjustable buffer support structure. When water impacts the protective plate 12, the impact force is transmitted to the movable frame 10 through the fixed seat 11, driving the sliding seat 9 to translate along the sliding rod 8. The displacement of the sliding seat 9 converts some of the impact energy, reducing the instantaneous load on the protective plate 12 and the main body 1 of the weir. This structure, through the linkage between the sliding seat 9 and the movable frame 10, achieves flexible buffering of the water flow impact force, avoiding structural damage caused by stress concentration under rigid connections. Simultaneously, the bolted connection of the fixed frame 6 facilitates installation and maintenance, improving the impact resistance and structural stability of the weir in hydraulic construction and extending its service life.

[0026] Reference Figure 4 and Figure 5 As shown in this embodiment: guide rods 13 are sleeved at both ends of the surface of the sliding seat 9. The two ends of the guide rods 13 are fixedly connected to the inner wall of the fixed frame 6. Buffer springs 14 are sleeved at both ends of the guide rods 13. One end of the buffer spring 14 is fixedly connected to the inner wall of the fixed frame 6. By fixing the guide rods 13 sleeved at both ends of the sliding seat 9 to the inner wall of the fixed frame 6, the sliding trajectory of the sliding seat 9 can be precisely limited to prevent it from deviating and shaking, ensuring motion stability. One end of the buffer spring 14 at both ends of the guide rods 13 is fixed to the inner wall of the fixed frame 6. When the sliding seat 9 is impacted and slides, it will compress the corresponding spring, causing it to elastically deform to absorb the impact kinetic energy and reduce the peak load transmitted to the weir body 1. At the same time, the spring's restoring energy drives the sliding seat 9 to return to its initial position, achieving repeated buffering.

[0027] Reference Figure 1 , Figure 2 and Figure 3As shown, specifically, the surface of the weir frame 3 is fixedly connected with a baffle plate 4, and the surface of the weir frame 3 is provided with several permeable holes 5. There are multiple baffle plates 4, and the cross-section of the baffle plates 4 is "S" shaped. The lower surface of the weir frame 3 is provided with a sealing brick layer 2, which is fixedly connected to the surface of the weir body 1. Through the multiple S-shaped baffle plates 4 fixed on the surface of the weir frame 3, the direction of water flow can be changed through the tortuous structure, the water flow resistance can be increased, the flow velocity can be slowed down to reduce the scouring force, and debris in the water can be intercepted at the same time. The permeable holes 5 on the surface of the weir frame 3 can divert part of the water flow, adjust the water level difference on both sides, and reduce the lateral pressure. The sealing brick layer 2 on the lower surface of the weir frame 3 is fixed to the weir body 1, which can enhance the connection sealing and prevent water leakage.

[0028] Working principle: The main body 1 of the weir serves as the core load-bearing structure. Its sloping weir frame 3 and lower fixed frame 6 form a collaborative protection system. The fixed frame 6 is securely connected to the main body 1 of the weir with bolts, ensuring reliable installation of the overall structure. When water flows onto the weir, it first passes through multiple S-shaped baffles 4 on the surface of the weir frame 3. The tortuous structure changes the direction of the water flow and increases flow resistance, thus slowing the flow velocity and reducing scouring force. Simultaneously, it intercepts debris in the water to prevent blockage. The permeable holes 5 on the surface of the weir frame 3 simultaneously divert part of the water flow, adjusting the water level difference on both sides of the weir and reducing lateral pressure. The sealing brick layer 2 on the lower surface of the weir frame 3 further enhances the weir's performance. The sealing of the main body 1 prevents water leakage. For water impact loads, the protective plate 12 directly bears the impact force and transmits it to the movable frame 10 through the fixed seat 11, driving the sliding seat 9 to translate along the sliding rod 8. The guide rods 13 sleeved at both ends of the sliding seat 9 precisely limit its sliding trajectory, preventing deviation and swaying, and ensuring motion stability. At the same time, the displacement of the sliding seat 9 compresses the buffer springs 14 at both ends of the guide rod 13, causing them to undergo elastic deformation to absorb the impact kinetic energy, converting the instantaneous load into a continuous elastic force, reducing the peak load transmitted to the fixed frame 6 and the main body 1 of the weir, and the spring's reset action can drive the sliding seat 9 to return to its initial position, achieving repeated buffering.
