The reinforcement plate includes a main body, which is square in shape. An upper connecting plate, a lower connecting plate, a left connecting plate, and a right connecting plate are fixedly installed on the outer side of the main body. The upper connecting plate and the lower connecting plate are fitted together, as are the left and right connecting plates. Fixing holes for anchor bolts to pass through are provided at each of the four corners of the main body.

Description

Technical Field

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

[0002] Pumped-storage hydroelectric power stations utilize electricity generated during off-peak hours to pump water into an upper reservoir, and then release the water into a lower reservoir to generate electricity during peak hours. Also known as pumped-storage hydroelectric power stations, they convert excess electricity generated during periods of low grid load into high-value electricity generated during peak periods. Pumped-storage dam slopes are susceptible to soil erosion. To reduce this erosion, reinforcement plates are used to strengthen the slopes. These plates are typically anchored to the slope using anchor bolts. Existing reinforcement plates either lack a connecting structure, leading to loose connections and misalignment between adjacent plates, or only have horizontal connections, resulting in loose vertical connections and misalignment between adjacent plates. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a pumped storage power station dam slope reinforcement device that can solve the above problems.

[0004] A pumped storage power station dam slope reinforcement device includes a reinforcement plate and anchor bolts. The reinforcement plate includes a reinforcement plate body, which has a square structure. An upper connecting plate, a lower connecting plate, a left connecting plate, and a right connecting plate are fixedly installed on the outer side of the reinforcement plate body. The upper connecting plate and the lower connecting plate fit together, and the left connecting plate and the right connecting plate fit together. Fixing holes for anchor bolts to pass through are opened at the four corners of the reinforcement plate body.

[0005] Furthermore, both the upper connecting plate and the lower connecting plate are L-shaped structures, and the number of the upper connecting plate and the lower connecting plate are the same. When the upper connecting plate and the lower connecting plate of adjacent reinforcing plates fit together, they form a plate-like structure with the same width as the body of the reinforcing plate.

[0006] Furthermore, the front and rear end faces of the upper connecting plate and the lower connecting plate are flush with the front and rear end faces of the reinforcing plate body.

When the left and right connecting plates of adjacent reinforcing plates fit together, they form a plate-like structure with the same width as the body of the reinforcing plate.

[0008] Furthermore, the rear end faces of the left and right connecting plates are flush with the rear end face of the reinforcing plate body, and the front end faces of the left and right connecting plates are lower than the front end face of the reinforcing plate body. When the left and right connecting plates of adjacent reinforcing plates fit together, a water guide groove is formed on the front side.

[0009] Furthermore, additional plates are provided at the top of the uppermost left connecting plate and at the bottom of the lowermost right connecting plate.

[0010] Furthermore, the anchor bolt includes a reinforcing cylinder and a screw. One end of the reinforcing cylinder is open, and the other end is closed and fixed with a conical head. Fins are provided on the outer side of the reinforcing cylinder. The reinforcing cylinder is located on the rear side of the reinforcing plate body and abuts against the rear end face of the reinforcing plate body. One end of the screw passes through the fixing hole and is spirally inserted into the reinforcing cylinder. The other end is fixed with a fixing head, which abuts against the front end face of the reinforcing plate body.

[0011] Furthermore, the screw is hollow and open at both ends, and the fixing head is provided with a grouting hole, which is connected to the inside of the screw.

[0012] Furthermore, a connecting ring is fixed to the outside of the fixing head, and a cable is provided between adjacent fixing heads, the cable being connected to the connecting ring.

[0013] Furthermore, the reinforcing plate body is provided with several mounting holes, and a protective net is provided in the mounting holes.

The upper connecting plate and the lower connecting plate fit together, and the left connecting plate and the right connecting plate fit together. This allows adjacent horizontal reinforcement plates and adjacent vertical reinforcement plates to be tightly connected, thereby effectively preventing the reinforcement plates from being misaligned in the horizontal and vertical directions. It also makes the reinforcement plates set on the dam slope form an integral load-bearing structure, enhancing the reinforcement effect. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, the pumped storage power station dam slope reinforcement device in this embodiment includes a reinforcement plate and anchor bolts. The reinforcement plate includes a reinforcement plate body 1, which has a square structure. An upper connecting plate 2, a lower connecting plate 3, a left connecting plate 4, and a right connecting plate 5 are fixedly installed on the outside of the reinforcement plate body 1. The upper connecting plate 2 and the lower connecting plate 3 fit together, and the left connecting plate 4 and the right connecting plate 5 fit together. Fixing holes for anchor bolts to pass through are opened at the four corners of the reinforcement plate body 1.

[0025] In this embodiment, both the upper connecting plate 2 and the lower connecting plate 3 are L-shaped structures with opposite directions, and the number of upper connecting plates 2 and lower connecting plates 3 is the same. Preferably, at least two upper connecting plates 2 and two lower connecting plates 3 are provided, and adjacent upper connecting plates 2 and adjacent lower connecting plates 3 are spaced apart, so that the gaps between adjacent upper connecting plates 2 and adjacent lower connecting plates 3 form slots, so that the upper connecting plate 2 is embedded in the slot between the adjacent lower connecting plates 3, and the lower connecting plate 3 is embedded in the slot between the adjacent upper connecting plates 2. After the upper connecting plates 2 and lower connecting plates 3 of adjacent reinforcing plates fit together, a plate-like structure with the same width as the reinforcing plate body 1 is formed.

[0026] In this embodiment, the front and rear end faces of the upper connecting plate 2 and the lower connecting plate 3 are flush with the front and rear end faces of the reinforcing plate body 1, so that the front and rear end faces of the plate-like structure formed by the upper connecting plate 2 and the lower connecting plate 3 between adjacent reinforcing plates are flush with the reinforcing plate body 1.

[0027] In this embodiment, both the left connecting plate 4 and the right connecting plate 5 are L-shaped structures with opposite directions, and the number of left connecting plates 4 and right connecting plates 5 is the same. Preferably, at least two left connecting plates 4 and two right connecting plates 5 are provided, and adjacent left connecting plates 4 and adjacent right connecting plates 5 are spaced apart, so that the gaps between adjacent left connecting plates 4 and adjacent right connecting plates 5 form slots, so that the left connecting plate 4 is embedded in the slot between the adjacent right connecting plate 5, and the right connecting plate 5 is embedded in the slot between the adjacent left connecting plate 4. After the left connecting plates 4 and right connecting plates 5 between adjacent reinforcing plates fit together, a plate-like structure with the same width as the reinforcing plate body 1 is formed.

[0028] In this embodiment, the rear end faces of the left connecting plate 4 and the right connecting plate 5 are flush with the rear end face of the reinforcing plate body 1, and the front end faces of the left connecting plate 4 and the right connecting plate 5 are lower than the front end face of the reinforcing plate body 1. After the left connecting plate 4 and the right connecting plate 5 of adjacent reinforcing plates fit together, a water guide groove 6 is formed on the front side. The top of the uppermost left connecting plate 4 is flush with the top of the reinforcing plate body 1, and the bottom of the lowermost right connecting plate 5 is flush with the bottom of the reinforcing plate body 1. An auxiliary plate 7 is provided on the top of the uppermost left connecting plate 4 and the bottom of the lowermost right connecting plate 5. The auxiliary plate 7 has the same width as the water guide groove 6, and the auxiliary plate 7 is flush with the front and rear end faces of the left connecting plate 4 and the right connecting plate 5.

[0029] By setting an upper connecting plate 2, a lower connecting plate 3, a left connecting plate 4, and a right connecting plate 5 on the outside of the reinforcing plate body 1, with the upper connecting plate 2 and the lower connecting plate 3 fitting together, and the left connecting plate 4 and the right connecting plate 5 fitting together, adjacent horizontal reinforcing plates and adjacent vertical reinforcing plates can be tightly connected, thereby effectively preventing the reinforcing plates from misaligning in the horizontal and vertical directions, and making the reinforcing plates set on the dam slope form an integral load-bearing structure, thus enhancing the reinforcement effect.

[0030] In this embodiment, the anchor bolt includes a reinforcing cylinder 8 and a screw 9. One end of the reinforcing cylinder 8 is open, and the other end is closed and fixed with a conical head 10. Fins 11 are provided on the outer side of the reinforcing cylinder 8. The reinforcing cylinder 8 is located on the rear side of the reinforcing plate body 1 and abuts against the rear end face of the reinforcing plate body 1. Internal threads are provided inside the reinforcing cylinder 8. One end of the screw 9 passes through a fixing hole and is helically inserted into the reinforcing cylinder 8. A fixing head 12 is fixed to the other end. The fixing head 12 is located on the front side of the reinforcing plate body 1 and abuts against the front end face of the reinforcing plate body 1. The screw 9 is hollow and open at both ends. The fixing head 12 is provided with a grouting hole 13, which communicates with the interior of the screw 9. After the screw 9 is helically inserted into the reinforcing cylinder 8, grout is injected into the reinforcing cylinder 8 through the grouting hole 13, thereby enhancing the firmness of the connection between the screw 9 and the reinforcing cylinder 8 and preventing the screw 9 from loosening due to rotation in the later stages of use.

[0031] In this embodiment, a connecting ring 14 is fixed to the outside of the fixing head 12. The four fixing rings are distributed in a circular array on the outside of the fixing head 12. A cable 15 is provided between adjacent fixing heads 12. The cable 15 is connected to the connecting ring 14, thereby connecting adjacent dam slope reinforcement devices through the cable 15, further improving the reinforcement effect.

[0032] The reinforcement plate body 1 is provided with several installation holes 16, and a protective net 17 is installed in the installation holes 16. The protective net 17 covers the surface of the dam slope. The soil base corresponding to the installation hole 16 is used to plant vegetation. The vegetation passes through the protective net and the roots of the vegetation penetrate into the soil base to further stabilize the soil and prevent soil erosion.

[0033] The working principle of the pumped storage power station dam slope reinforcement device in this embodiment is as follows:

[0034] In practical use, multiple reinforcing plates are assembled and placed on the dam slope, with the plates tightly attached to the slope surface. Adjacent reinforcing plates are joined together by upper connecting plate 2, lower connecting plate 3, left connecting plate 4, and right connecting plate 5, ensuring a tight connection between adjacent horizontal and vertical reinforcing plates. This effectively prevents misalignment of the reinforcing plates in the horizontal and vertical directions and forms a unified load-bearing structure on the dam slope. The reinforcing cylinder 8 is inserted into the soil foundation of the dam slope. Due to the fins 11 on the outside of the reinforcing cylinder 8, it can be firmly anchored within the dam slope. The screw 9 is spirally inserted into the reinforcing cylinder 8, and grout is injected into the reinforcing cylinder 8 through the grouting hole 13, thereby enhancing the connection between the screw 9 and the reinforcing cylinder 8 and preventing the screw 9 from loosening during later use. Finally, cables 15 are installed between adjacent fixing heads 12 to improve the stability of the entire device.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
