Description

Technical Field

[0001] This utility model relates to the field of water conservancy facilities technology, and in particular to a water conservancy sine wave plate, stilling basin, slope protection plate and slope protection structure. Background Technology

[0002] In the construction of water conservancy projects, it is often necessary to design specific devices or structures to cope with the impact or scouring of water flow. Examples include stilling basins downstream of dam spillways that serve to dissipate energy, and revetments that protect riverbank surfaces during the construction of river channels in rainy areas.

[0003] The stilling basin downstream of the dam spillway is designed with a certain water cushion depth to cope with the impact of high-falling water flow, but the bottom of the stilling basin is mostly a planar or rectangular structure, which has limited energy dissipation effect.

[0004] Currently, bank protection is mainly divided into two categories: traditional hard bank protection and ecological bank protection. Ecological bank protection is complex to construct and has poor stability in the early stages, resulting in high maintenance costs. Traditional hard bank protection mostly adopts linear or planar structures, which mainly rely on the strength of the material itself to resist water erosion. It cannot effectively disperse the energy of water flow, which can easily lead to local erosion. After long-term impact from water flow, cracks and peeling are likely to occur. In addition, the hard surface blocks the exchange of water and soil, which is not conducive to vegetation growth. Utility Model Content

[0006] This application provides a hydraulic sine wave plate, wherein any longitudinal section along the center of the hydraulic sine wave plate has a continuous sine wave, and multiple degassing holes are provided through the hydraulic sine wave plate, with the multiple degassing holes being distributed at intervals.

[0007] The beneficial effects of the above embodiments are as follows: the hydraulic sine wave plate adopts a continuous sinusoidal waveform surface. When the surface of the hydraulic sine wave plate is impacted by water flow at different angles, strong dynamics are generated through swirling, friction, and hydraulic jumps, increasing energy consumption and thus dissipating energy and waves. By setting de-gas holes, the negative pressure in the water body is reduced, thereby reducing the scouring and cavitation of the downstream water flow. This hydraulic sine wave plate can effectively dissipate energy, dissipate waves, and prevent erosion, and can be widely used in hydraulic facilities.

[0008] This application embodiment also provides a stilling basin, applied downstream of a dam spillway, including the aforementioned hydraulic sine wave plate and concrete structure. The hydraulic sine wave plate is disposed on the upper surface of the concrete structure, and the concrete structure is also provided with the degassing holes corresponding to the hydraulic sine wave plate.

[0009] The beneficial effects of the above embodiments are as follows: compared with stilling pools with planar or rectangular structures, stilling pools using this hydraulic sine wave plate have reduced residual energy, higher energy dissipation efficiency, and better energy dissipation effect.

[0010] Based on the above embodiments, this application can be further improved as follows: In one embodiment of this application, the waveform curve equation of the hydraulic sine wave plate with the center as the origin is z=Asin( (A) represents the peak value, and B represents the wavelength control parameter. The hydraulic sine wave plate has a three-dimensional sine wave surface, and the A / B parameters can be adjusted according to actual needs, making it highly adaptable.

[0011] In one embodiment of this application, A is H / 3, where H is the water cushion depth. Multiple experiments have verified that the energy dissipation effect is best when A is close to H / 3.

[0012] This application embodiment also provides a slope protection board, which is composed of an array of multiple hydraulic sine wave plates as shown above. The hydraulic sine wave plates are circular, and the outer edges of adjacent hydraulic sine wave plates are connected to each other.

[0013] The beneficial effects of the above embodiments are as follows: the hydraulic sine wave plate adopts a continuous sinusoidal waveform surface, which can effectively disperse the water flow and resist erosion when water waves scour; the outer edges of adjacent hydraulic sine wave plates form ecological through holes for the growth of green plants. This slope protection plate has the effects of efficient wave dissipation and erosion prevention, and is ecologically friendly. It is not easily damaged and has a good slope protection effect. It can be combined with green plants to enhance its aesthetics.

[0014] Based on the above embodiments, this application can be further improved as follows: In one embodiment of this application, a reinforcing rib is provided at the outer edge connection of adjacent hydraulic wave plates, resulting in a more stable connection.

[0015] In one embodiment of this application, the hydraulic chord plates in adjacent rows are staggered. This increases the number of contact points at the outer edges of adjacent hydraulic chord plates, resulting in a more stable structure.

[0016] This application embodiment also provides a slope protection structure, including the aforementioned slope protection panels and aquatic plants. The slope protection panels are installed in the floodplain area of ​​a river channel, and the outer edges of adjacent slope protection panels form the ecological through holes. The aquatic plants are placed in the ecological through holes. Planting aquatic soil-stabilizing plants within the ecological through holes enhances soil and water conservation capabilities; the slope protection panels dissipate energy and waves, protecting the slope while simultaneously protecting the plant roots and improving early survival rates.

When encountering the impact of water flow, it generates strong turbulence through multiple hydraulic jumps and swirls, thereby dissipating energy and waves.

[0027] This application provides a hydraulic sine wave plate, stilling basin, slope protection plate and slope protection structure, which solves the problem of poor energy dissipation and wave reduction effect in existing hydraulic facilities in response to water flow impact, and achieves a highly efficient energy dissipation and wave reduction effect.

[0028] The technical solution in this application is to solve the above problems, and the overall approach is as follows: Example 1: like Figure 1-2 As shown, a hydraulic sine wave plate 1 is provided. Any longitudinal section of the hydraulic sine wave plate 1 along its center has a continuous sine wave. Multiple degassing holes 11 are provided through the hydraulic sine wave plate 1, and the multiple degassing holes 11 are distributed at intervals.

[0029] The hydraulic sine wave plate adopts a continuous sinusoidal waveform surface. When it meets the impact of water flow, it generates strong turbulence by producing multiple hydraulic jumps and swirls to dissipate energy and waves. It is equipped with degassing holes to reduce negative pressure in the water body and reduce the scouring and cavitation of the downstream water flow.

[0030] Example 2: like Figure 3 As shown, a stilling basin is used downstream of a dam spillway, including a hydraulic sine wave plate 1 and a concrete structure 2 as shown in Example 1. The hydraulic sine wave plate 1 is disposed on the upper surface of the concrete structure 2, and the concrete structure 2 is also provided with air de-gas holes 11 corresponding to the hydraulic sine wave plate 1.

[0031] Compared to stilling pools with planar or rectangular structures, stilling pools using this hydraulic sine wave plate have lower residual energy, higher energy dissipation efficiency, and better energy dissipation effect.

[0033] Furthermore, A is equal to H / 3, where H is the depth of the water cushion.

The outer edges of adjacent hydraulic sine wave boards 1 surround each other to form ecological through holes 3.

[0035] Furthermore, reinforcing ribs 4 are added at the outer edge connection of adjacent hydraulic sine wave plates 1, making the connection more stable.

[0036] Optional, such as Figure 5 As shown, the hydraulic chord wave plates 1 in adjacent rows are staggered, increasing the contact points on the outer edges of adjacent hydraulic chord wave plates 1, making the structure more stable.

[0037] Example 4: like Figure 6 As shown, a slope protection structure includes the aforementioned slope protection slab 5 and aquatic plants 6. The slope protection slab 5 is installed in the floodplain area of ​​a river channel, and the outer edges of adjacent slope protection slabs 5 form ecological through holes. The aquatic plants 6 are placed in the ecological through holes. Aquatic soil-stabilizing plants are planted in the ecological through holes to enhance soil and water conservation capacity; the slope protection slabs absorb energy and waves to protect the slope, while also protecting the plant roots and improving the early survival rate.
