Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a slope protection structure for water conservancy projects. Background Technology

[0002] In water conservancy projects, slopes are frequently subjected to erosion by water waves, leading to severe soil erosion. To address this problem, slope protection structures are typically used for prevention and protection. Some existing slope protection structures (such as the water conservancy engineering slope protection structure disclosed in application number CN202421148767.4) achieve adjustable buffer plate angles through the design of hinged seats, buffer plates, and locking components. This allows the buffer plates to be erected during the flood season to block the impact of water flow and reduce erosion of the slope; while during the non-flood season or when the water level drops, part of the buffer plate can be folded to fit against the top plane of the transverse concrete ribs, avoiding obstruction of vegetation, promoting plant growth, and further reducing soil erosion.

[0003] However, although the aforementioned slope protection structure can flexibly adjust the angle of the buffer plates according to different water levels, thereby meeting the needs of slope protection and providing a good growth environment for vegetation, its main drawback is that the adjustment of the buffer plate angle relies on manual operation. Since the flood season often arrives very quickly, it is difficult to complete the angle adjustment of all buffer plates in a short time; this is not only time-consuming and labor-intensive, but also difficult to ensure timeliness and accuracy in emergency situations. To address these problems, this utility model proposes a hydraulic engineering slope protection structure capable of automatically adjusting the angle of the buffer plates. Utility Model Content

[0004] The purpose of this utility model is to provide a slope protection structure for water conservancy projects to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution:

[0006] A slope protection structure for hydraulic engineering, installed on the slope of a river, includes a separating component, a buffer plate, and a rebound component. The separating component is laid on the water-facing slope and divides the water-facing slope into several vegetation planting areas. The buffer plate has a first side and a second side arranged opposite to each other along its width. The first side of the buffer plate is rotatably connected to the separating component located in front of the vegetation planting area, and the density of the buffer plate is less than the density of water in the river. The rebound component is disposed between the buffer plate and the separating component and can provide a rebound force for the buffer plate to flip towards the center of the river.

[0007] Optionally, a connecting seat is fixedly provided on the partition member, and the first side of the buffer plate is rotatably connected to the connecting seat through a rotating shaft.

[0008] Optionally, the buffer plate includes a main body and an extension plate. The main body is rotatably connected to the partition member, and the extension plate is elastically connected to the main body through an elastic element. One side of the extension plate is bent in the thickness direction of the buffer plate to form a folded edge.

[0009] Optionally, the elastic element is a compression spring, the main body is provided with a plug hole for accommodating the extension plate, the end face of the main body is provided with a sliding hole communicating with the plug hole, the end face of the extension plate is fixedly provided with a slider, and the compression spring is disposed in the sliding hole.

[0010] Optionally, a positioning shaft is fixedly provided on the slider and arranged along the width direction of the buffer plate, the main body is provided with a positioning hole for the positioning shaft to move through, and the compression spring is sleeved on the positioning shaft.

[0011] Optionally, the rebound member is a C-shaped spring sheet, and the two ends of the spring sheet are fixed to the buffer plate.

[0012] Optionally, the separating component includes a plurality of transversely spaced retaining walls and a plurality of longitudinally spaced retaining walls.

[0013] Optionally, a longitudinal drainage channel is provided within the longitudinal retaining wall, and a first drainage hole communicating with the longitudinal drainage channel is provided on the side of the longitudinal retaining wall facing the vegetation planting area. The lower end of the longitudinal drainage channel extends into the river channel and is provided with a drainage outlet.

[0014] Optionally, a transverse drainage channel communicating with the longitudinal drainage channel is provided inside the transverse retaining wall, and a second drainage hole communicating with the transverse drainage channel is provided on the side of the transverse retaining wall facing the vegetation planting area.

[0015] Optionally, a water storage tank is fixedly installed on the side of the transverse retaining wall facing the water-facing slope, and the water storage tank is filled with a layer of sand and gravel.

[0016] Compared with the prior art, this utility model provides a slope protection structure for hydraulic engineering, which has the following characteristics:

[0017] Beneficial effects:

[0018] 1. This utility model sets up a partition component, a buffer plate, and a rebound component. The density of the buffer plate is less than that of the water in the river. This allows the buffer plate to automatically adjust its angle according to changes in water level. This not only reduces the impact of water waves on the soil in the vegetation planting area, but also ensures that the buffer plate can automatically fold up when the water level drops, thereby reducing the adverse effects of the buffer plate on vegetation growth.

[0019] 2. The buffer plate of this utility model includes a main body and an extension plate. When the buffer plate is impacted by the waves in the river, its overall lateral area will automatically increase under the impact of the waves, thereby achieving a better shielding effect. Furthermore, when the water level drops, the overall lateral area of ​​the buffer plate will reduce the rebound force of the elastic element, thus preventing the buffer plate from blocking the plants in the lower vegetation planting area due to its excessive size.

[0020] 3. By setting up a longitudinal drainage channel, a first drainage hole and a drainage outlet, this utility model allows a portion of the water entering the vegetation planting area to be directly discharged into the longitudinal drainage channel through the first drainage hole, and then discharged into the river channel through the drainage outlet at the lower end of the longitudinal drainage channel. This reduces the amount of water overflowing from the upper vegetation planting area to the lower vegetation planting area, thereby reducing the impact of water flow on the soil of the lower vegetation planting area.

[0030] 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.

[0031] Example: Please refer to Figures 1 to 8 According to an embodiment of the present invention, a slope protection structure for a water conservancy project is provided. The slope protection structure is installed on the slope 1 of a river channel and includes a separating member 2, a buffer plate 3, and a rebound member 4. The separating member 2 is laid on the water-facing slope 10 of the slope 1 and divides the water-facing slope 10 into several vegetation planting areas 11. The buffer plate 3 has a first side and a second side arranged opposite to each other along its width direction. The first side of the buffer plate 3 is rotatably connected to the separating member 2 located in front of the vegetation planting area 11. The front side of the vegetation planting area 11 is the side of the vegetation planting area 11 closer to the center of the river channel. The density of the buffer plate 3 is less than the density of the water in the river channel, that is, the buffer plate 3 can float in the water in the river channel. When the buffer plate 3 is submerged in water, the side facing down is the first side and the side facing up is the second side. The rebound member 4 is disposed between the buffer plate 3 and the separating member 2 and can provide a rebound force for the buffer plate 3 to flip towards the center of the river channel.

[0032] When the water level is below the buffer plate 3, the buffer plate 3 will fold up onto the partition member 2 under its own weight. At this time, the buffer plate 3 will not block the vegetation planting area 11, ensuring that the vegetation in the vegetation planting area 11 can receive as much sunlight as possible. When the water level rises to submerge the buffer plate 3, the buffer plate 3 will automatically flip upward at a certain angle under the action of buoyancy. After flipping, the buffer plate 3 will block the front side of the vegetation planting area 11, which can reduce the erosion of the soil in the vegetation planting area 11 by the water waves. When the water level drops again, the buffer plate 3 can flip downward onto the partition member 2 under the action of its own weight and the rebound force of the rebound member 4, thus removing the blockage to the vegetation planting area 11. Therefore, the slope protection structure of this water conservancy project can automatically adjust the angle of the buffer plate 3 according to the change of water level. This not only reduces the impact of water waves on the soil in the vegetation planting area 11, but also ensures that the buffer plate 3 can automatically fold up when the water level drops, thereby reducing the adverse effects of the buffer plate 3 on vegetation growth.

[0033] like Figure 5 As shown, in order to achieve a rotatable connection between the first side of the buffer plate 3 and the partition member 2, in this exemplary embodiment, a connecting seat 5 is fixedly provided on the partition member 2, and the first side of the buffer plate 3 is rotatably connected to the connecting seat 5 via a rotating shaft 6. In other embodiments, the first side of the buffer plate 3 may also be rotatably connected to the connecting seat 5 via a hinge or a hinge chain.

[0034] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, to improve the shielding effect of the buffer plate 3, in this exemplary embodiment, the buffer plate 3 includes a main body 30 and an extension plate 31. The main body 30 is rotatably connected to the partition member 2, and the extension plate 31 is elastically connected to the main body 30 through an elastic element. One side of the extension plate 31 is bent towards the thickness direction of the buffer plate 3 to form a folded edge 310. With this configuration, when the buffer plate 3 is not impacted by water waves, the overlapping area of ​​the main body 30 and the extension plate 31 is relatively large, and the overall lateral area of ​​the buffer plate 3 is relatively small. However, when the buffer plate 3 is impacted by water waves in the river, the water waves will impact the folded edge 310 of the extension plate 31, causing the extension plate 31 to unfold, reducing the overlapping area of ​​the main body 30 and the extension plate 31, and increasing the overall lateral area of ​​the buffer plate 3, thereby achieving a better shielding effect. When the water level drops, the impact of the water waves on the extension plate 31 disappears, and the extension plate 31 will retract under the rebound force of the elastic element. At this time, the overall lateral area of ​​the buffer plate 3 will become smaller, which can prevent the plants in the lower vegetation planting area 11 from being blocked due to the excessive volume of the buffer plate 3.

[0035] like Figure 5 , Figure 6 and Figure 7 As shown in this exemplary embodiment, the elastic element is a compression spring 32, the main body 30 is provided with a plug hole 300 that can accommodate the extension plate 31, the end face of the main body 30 is provided with a sliding hole 301 communicating with the plug hole 300, the end face of the extension plate 31 is fixedly provided with a slider 311, and the compression spring 32 is provided in the sliding hole 301.

[0036] like Figure 7 As shown in this exemplary embodiment, a positioning shaft 312 arranged along the width direction of the buffer plate 3 is fixedly provided on the slider 311, and the main body 30 is provided with a positioning hole 302 through which the positioning shaft 312 moves. The compression spring 32 is sleeved on the positioning shaft 312. With this arrangement, on the one hand, the positioning shaft 312 can improve the stability of the extension plate 31 when sliding, and on the other hand, the positioning shaft 312 can limit the position of the compression spring 32 and reduce the displacement that occurs during the extension and contraction of the compression spring 32.

[0037] like Figure 8 As shown, in another embodiment, the elastic element can also be an elastic rope 33. The main body 30 is provided with a plug hole 300 that can accommodate the extension plate 31. The elastic rope 33 is provided in the plug hole 300. One end of the elastic rope 33 is fixed to the main body 30, and the other end is fixedly connected to the extension plate 31. This can also realize the elastic connection between the extension plate 31 and the main body 30.

[0038] like Figure 5 and Figure 6 As shown in this exemplary embodiment, the spring-loaded member 4 is a C-shaped spring sheet, with both ends of the spring sheet fixed to the buffer plate 3. The fixed connection between the spring sheet and the buffer plate 3 includes, but is not limited to, welding, screw connection, and snap-fit. Of course, as long as it can provide a spring-loaded force for the buffer plate 3 to flip towards the center of the river channel, there are no particular restrictions on the specific structural form of the spring-loaded member 4.

[0039] like Figure 4 As shown in this exemplary embodiment, the separating member 2 includes a plurality of transversely spaced retaining walls 20 and a plurality of longitudinally spaced retaining walls 21. Specifically, the transverse retaining walls 20 and the longitudinal retaining walls 21 can be an integral grid structure made of cast concrete, and each grid can be regarded as a vegetation planting area 11.

[0040] like Figure 3 and Figure 4As shown, during rainy days, rainwater falls into the vegetation planting area 11. When the rainfall is heavy, the water in the upper vegetation planting area 11 will overflow into the lower vegetation planting area 11. This makes the soil in the lower vegetation planting area 11 more susceptible to erosion by the water flow. In order to reduce the erosion of the soil in the lower vegetation planting area 11 by the water flow, in this exemplary embodiment, a longitudinal drainage channel is provided in the longitudinal retaining wall 21 along its length. A first drainage hole 210 communicating with the longitudinal drainage channel is provided on the side of the longitudinal retaining wall 21 facing the vegetation planting area 11. The lower end of the longitudinal drainage channel extends into the river channel and is provided with a drainage outlet 211. This design allows some of the water entering the vegetation planting area 11 to be directly discharged into the longitudinal drainage channel of the longitudinal retaining wall 21 through the first drainage hole 210, and then discharged into the river channel through the drainage outlet 211 at the lower end of the longitudinal drainage channel. This reduces the amount of water overflowing from the upper vegetation planting area 11 to the lower vegetation planting area 11, thereby reducing the impact of water flow on the soil of the lower vegetation planting area 11.

[0041] like Figure 2 As shown, to reduce the erosion of the soil in the lower vegetation planting area 11 by water flow, in this exemplary embodiment, a transverse drainage channel communicating with the longitudinal drainage channel is provided along the length of the transverse retaining wall 20. A second drainage hole 200 communicating with the transverse drainage channel is provided on the side of the transverse retaining wall 20 facing the vegetation planting area 11. With this arrangement, some rainwater falling into the vegetation planting area 11 can be directly discharged into the transverse drainage channel through the second drainage hole 200, and then discharged into the longitudinal drainage channel from the transverse drainage channel, and finally discharged into the river channel through the drainage outlet 211 at the lower end of the longitudinal drainage channel. This can achieve the effect of faster drainage of rainwater entering the vegetation planting area 11. Of course, in order to reduce the soil discharged from the first drainage hole 210 and the second drainage hole 200, and at the same time reduce the possibility of blockage in the longitudinal drainage channel and the transverse drainage channel, a filter screen is provided at the positions of the first drainage hole 210 and the second drainage hole 200.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, generally speaking, the moisture content of a slope decreases as it rises, which may cause water shortage in the upper vegetation planting area 11. To reduce or avoid this phenomenon, in this exemplary embodiment, a water storage tank 7 is fixedly installed on the side of the transverse retaining wall 20 facing the water-facing slope 10, and the water storage tank 7 is filled with a layer of sand and gravel 8. The water storage tank 7 is specifically a V-shaped plate structure with an open top and closed ends, and is located below the vegetation planting area 11. With this configuration, the water storage tank 7 can store a portion of water during rainy days. This water can continuously provide moisture to the vegetation planting area 11, especially the vegetation in the upper vegetation planting area 11, for a period of time, ensuring that the vegetation in the upper vegetation planting area 11 can grow better, and further reducing soil erosion. Secondly, the sand and gravel layer 8 can increase the water storage capacity of the water storage tank 7.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown in this exemplary embodiment, a hollow-structured water-passing plate 9 is laid on the top of the slope protection. The top of the water-passing plate 9 is provided with water-passing holes 90, and the bottom of the water-passing plate 9 is connected to the longitudinal drainage channel of the longitudinal retaining wall 21. During rainy weather, rainwater falling on the top of the water-passing plate 9 can enter the water-passing plate 9 through the water-passing holes 90, then enter the longitudinal drainage channel, and finally drain into the river channel through the drain outlet 211 at the lower end of the longitudinal drainage channel. This prevents rainwater falling on the top of the water-passing plate 9 from flowing into the vegetation planting area 11, causing erosion of the soil in the vegetation planting area 11, and further prevents soil loss in the vegetation planting area 11.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
