Description

Technical Field

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

[0002] Pumped-storage hydroelectric power stations utilize electricity generated during periods of low electricity demand to pump water into an upper reservoir, and then release the water into a lower reservoir to generate electricity during periods of high demand. They are also known as pumped-storage hydroelectric power stations. They can convert excess electricity generated during periods of low grid load into high-value electricity generated during periods of high grid load. Pumped-storage power station dams are susceptible to soil erosion, and to reduce this erosion, dam slope reinforcement is necessary.

[0003] Since dam slope reinforcement mainly involves laying wire mesh and then pressing it with pressure plates, the existing pressure plates have certain drawbacks. First, the existing pressure plates are not easy to combine and splice, and the spliced ​​pressure plates do not have better stability. Second, the existing pressure plates do not have wave resistance, which has a certain impact. Therefore, there is an urgent need for a pumped storage power station dam slope reinforcement device to solve the above problems. Utility Model Content

[0004] To solve the above problems, this utility model provides a pumped storage power station dam slope reinforcement device, which is achieved through the following technical solution.

[0005] A pumped storage power station dam slope reinforcement device includes:

[0006] The pressure plate consists of several plates that are spliced ​​together and attached to the dam slope. Each pressure plate has trapezoidal wedges and trapezoidal grooves on its adjacent sides, and fan-shaped openings at the corners of its sides.

[0007] Wave-breaking stones, which are fixedly connected to the center position of the top of the pressure plate;

[0008] A grounding rod, the outer surface of which is provided with several spikes, and a circular positioning plate is fixedly connected to one end of the grounding rod, the circular positioning plate having threaded holes;

[0009] The extrusion seat has a screw fixedly connected to its bottom and an internal hexagonal groove on its top.

[0010] Furthermore, the trapezoidal wedges and trapezoidal slots on two adjacent pressure plates are interlocked and engaged with each other.

[0011] Furthermore, the four fan-shaped openings are spliced ​​together to form a complete circle, and the circular positioning plate is embedded in the fan-shaped openings for limitation.

[0012] Furthermore, the other end of the ground-inserting pole is provided with a pointed tip, and the pointed tip of the ground-inserting pole is inserted into the dam slope.

[0013] Furthermore, the screw is threadedly engaged with the circular positioning plate through a threaded hole, and one end of the screw extends through the threaded hole into the interior of the grounding rod.

[0014] Furthermore, the pressing seat presses against the top of the pressure plate.

[0015] Furthermore, the top of the pressure plate is provided with a planting hole, and the planting hole is coaxial with the through hole on the wave-breaking stone.

[0016] The beneficial effects of this utility model are as follows: During the operation of this device, several pressure plates are first laid flat on the dam slope. Adjacent pressure plates are connected and combined with each other through trapezoidal wedges and trapezoidal slots. Then, four adjacent pressure plates are combined into a complete circle through fan-shaped openings. The tip of the ground-inserting rod is inserted into the dam slope from the complete circle and fixed. The circular positioning plate is embedded between the four fan-shaped openings. Finally, the screw on the extrusion seat is rotatably connected to the circular positioning plate through the threaded hole. The extrusion seat can press and fix the four adjacent pressure plates, which facilitates the adhesion of several pressure plates to the dam slope for fixation, thereby improving the firmness of the reinforcement. The wave-damping stones fixed on the pressure plates can reduce the impact of water waves, thereby reducing the impact force on the dam slope. The structure is reasonable and can reinforce and protect the dam slope. Attached Figure Description
