Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower technology, and in particular to a pumped storage power station dam slope reinforcement device. Background Technology

[0002] Pumped storage power stations serve multiple functions within their power systems, including peak shaving, valley filling, and energy storage. As the service life of the power station increases, problems such as weakening of the soil and rock mass, crack development, and potential for localized landslides may occur on the dam slope. In such cases, effective reinforcement measures must be taken immediately to prevent dam slope instability and subsequent shutdown of the power station.

[0003] Existing reinforcement methods include cast-in-place concrete retaining walls, anti-slide pile support, and geogrid installation. However, these methods have limitations in practical applications. They cannot flexibly adjust the reinforcement angle and support strength according to the actual slope and stress differences in different areas of the dam slope, making it difficult to achieve precise adaptation.

[0004] A dam slope reinforcement device disclosed in patent publication number CN221760596U includes a fixed plate, a connecting plate hinged to the fixed plate, and an adjusting assembly. The adjusting assembly includes a rotating rod hinged to the connecting plate and a fixed rod hinged to the fixed plate, with the rotating rod and fixed rod hinged together. When the rotating rod is rotated so that it is aligned with the fixed rod, the position of the connecting plate is locked, providing support for the dam slope. Conversely, rotating the rotating rod so that it is not aligned with the fixed rod unlocks the connecting plate. This device provides support at only one angle, namely the dead point where the rotating rod and fixed rod are aligned. Therefore, this device is not suitable for different slopes and has limitations. Utility Model Content

[0005] The purpose of this utility model is to provide a pumped storage power station dam slope reinforcement device that can be used for reinforcement and support of different slopes.

[0006] The technical solution of this utility model is: a pumped storage power station dam slope reinforcement device, including a base, a reinforcement plate hinged to the base, and an angle adjustment mechanism. The angle adjustment mechanism includes a slide rod slidably connected to the base, an adjustment rod hinged between the slide rod and the reinforcement plate, and a driving component for driving the slide rod to slide. The driving component is located inside the base. The slide rod is provided with a rack, and the driving component is provided with a gear that meshes with the rack.

[0007] In the above scheme, the angle adjustment mechanism used to drive the reinforcement plate to adjust its angle and securely support it on the dam slope is designed as a gear and rack drive method, which can achieve stepless adjustment and has good self-locking performance. The stepless adjustment function enables the reinforcement plate to be adjusted at any angle to suit the actual slope of the dam slope in different areas. The self-locking function achieves stable support and reliable reinforcement, ensuring the strength of the support.

[0008] Preferably, the slide bar includes a movable rod and a movable block; the base has a mounting cavity, and the upper wall of the mounting cavity formed by the base has a first sliding groove; the driving component is disposed in the mounting cavity; The upper end of the moving block is connected to the moving rod, and the lower end of the moving block is connected to the upper end of the rack; the moving block is slidably connected in the first groove; the adjusting rod is connected to the moving rod.

[0009] Preferably, the lower wall of the mounting cavity formed by the base is provided with a third sliding groove, and the lower end of the rack is connected to a sliding plate, which is slidably connected in the third sliding groove.

[0010] Preferably, the two ends of the lower surface of the movable rod are connected to sliders, and the upper wall of the mounting cavity formed by the base is provided with two second sliding grooves corresponding to the sliders, and the sliders are slidably connected in the second sliding grooves.

[0011] Preferably, the upper end of the reinforcing plate is provided with mounting holes.

[0012] Preferably, positioning stakes are detachably installed around the bottom of the base.

[0013] Preferably, the driving component includes a motor, and the gear is mounted on the motor shaft.

[0014] Compared with related technologies, the beneficial effects of this utility model are as follows: I. The angle adjustment mechanism of this utility model is used to drive the reinforcement plate to adjust the angle and support it on the dam slope. The angle adjustment mechanism is designed with a gear and rack drive method, which can realize stepless adjustment and has good self-locking performance. The stepless adjustment function realizes the adjustment of the reinforcement plate at any angle to suit the actual slope of the dam slope in different areas. The self-locking function realizes stable support and reliable reinforcement, ensuring the strength of the support. Second, the driving component of this utility model adopts a motor, which enables a more precise angle adjustment method and has stable and reliable self-locking performance; 3. When the angle of the reinforcing plate is adjusted, the slide rod slides in the corresponding slide groove on the base to ensure that the position of the adjusting rod does not shift during the adjustment process, so that the force output by the adjusting rod to the reinforcing plate is always consistent. Fourth, the base is equipped with detachable positioning piles, which can be inserted into the soil of the dam slope foundation to improve the stability of the support. In addition, the detachable nature of the positioning piles makes it easy to replace them, ensuring that the maintenance and replacement of the positioning piles is convenient and efficient.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0018] like Figure 1 As shown in the figure, the pumped storage power station dam slope reinforcement device provided in this embodiment includes a base 1, an angle adjustment mechanism 2, a reinforcement plate 3, and a positioning pile 4.

[0019] like Figure 1 , Figure 2 As shown, the base 1 has a mounting cavity 13, and a top cover plate 15 is bolted onto the mounting cavity 13. A first sliding groove 11 extending along the Y direction is formed on the top cover plate 15. A third sliding groove 14 extending along the Y direction is formed on the bottom plate of the base 1 forming the mounting cavity 13. The first sliding groove 11 and the third sliding groove 14 are vertically aligned and of equal length. The base 1 also has two second sliding grooves 12, located at both ends of the first sliding groove 11 in the X direction, and extending along the Y direction.

[0020] The lower end of the reinforcing plate 3 is rotatably connected to the base 1 via a rotating shaft 32, and the upper end of the reinforcing plate 3 is provided with mounting holes 31, which are located at both ends in the X direction.

[0021] like Figure 1 , Figure 3 As shown, the angle adjustment mechanism 2 includes a slide rod 21, an adjusting rod 22, and a driving member 23. The slide rod 21 includes a moving rod 211, a sliding plate 212, a slider 213, a moving block 214, and a rack 215. The moving rod 211 extends along the X direction, and its lower surface is connected to the slider 213 and the moving block 214. The slider 213 is located at both ends of the moving rod 211. The lower end of the moving block 214 is connected to the rack 215, which extends along the Y direction. The lower end of the rack 215 is connected to the sliding plate 212. The sliders 213 are fitted into the second slide groove 12, the moving blocks 214 are fitted into the first slide groove 11, and the sliding plates 212 are fitted into the third slide groove 14. The driving member 23 is disposed in the mounting cavity 13. The drive unit 23 includes a motor 231 and a gear 232 connected to the motor shaft of the motor 231, the gear 232 meshing with a rack 215.

[0022] like Figure 2 As shown, positioning posts 4 are detachably installed around the bottom of the base 1. The base 1 has threaded holes, and the upper end of the positioning post 4 is a stud. The stud is coated with anti-rust grease and then threadedly connected to the threaded hole. The outer surface of the positioning post 4 is coated with anti-rust paint. The anti-rust grease effectively prevents thread corrosion and jamming caused by long-term humid environments and further reduces disassembly resistance.

[0023] In use, first select a suitable length of positioning pile 4 based on the actual working conditions such as soil hardness and foundation stability in the dam slope reinforcement area, and install it on the base 1. Start the motor 231 to drive the gear 232 to rotate, thereby driving the rack 215 to move along the Y direction. The moving rod 211, which is integrally connected to the rack 215, moves together with it, driving the adjusting rod 22 to push the reinforcement plate 3 to rotate counterclockwise or clockwise, so as to adjust the tilt angle of the reinforcement plate 3 and make the reinforcement plate 3 completely fit with the dam slope. After fitting, turn off the motor 231. Through the self-locking performance of the motor 231, the position of the reinforcement plate 3 is locked, forming a stable and reliable support and reinforcement.

[0024] The pumped-storage power station dam slope reinforcement device effectively supports the dam slope and resists the risk of slope collapse by tightly fitting and auxiliary fixing the reinforcement plate 3 to the dam slope. After the reinforcement plate 3 is adjusted to an angle suitable for the dam slope gradient, the installation holes 31 on the reinforcement plate 3 allow it to be fixed to the soil and rock mass on the dam slope surface using anchor rods, bolts, and other connecting components, forming an integrated load-bearing structure. At this point, the reinforcement plate 3 can directly bear the lateral pressure and seepage pressure loads of the dam slope soil and rock mass, and transfer the load to the base 1 through the adjusting rod 22 and sliding rod 21. Finally, the base 1 transfers the load to the deep foundation of the dam slope through the positioning piles 4, achieving load distribution and bearing. Simultaneously, the presence of the reinforcement plate 3 effectively prevents rainwater erosion and soil loss from the dam slope surface, reducing external environmental erosion of the dam slope, further improving the stability of the dam slope, and achieving long-term reinforcement and protection.
