Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy engineering, in particular to a water conservancy engineering flood prevention slope protection structure. BACKGROUND

[0002] The water conservancy engineering flood prevention slope protection structure refers to the engineering facilities and protection structures built on the slope around the water area such as river, lake, reservoir and coast, which are used to resist flood erosion, wind wave erosion, prevent water and soil loss and maintain the stability of the slope. It is like a layer of "armor" for the shore of the water body, which ensures that the shore slope will not collapse, landslide and soil loss under the impact of high water level, large flow and strong wind wave in the flood season.

[0003] The area close to the water edge often has a "grid" shaped slope protection structure. This slope protection structure is composed of countless small prefabricated blocks, which has good flexibility. When the ground foundation deforms slightly, the single small prefabricated block can adjust and displace slightly, and the entire slope protection structure will not be damaged.

[0004] When the flood season comes, a large amount of heavy rainfall in a short period of time will cause the water level to rise rapidly. With the rise of the water level, the pressure borne by the slope protection structure will also gradually increase. Although the "grid" structure slope protection structure can drain water, a large amount of water will flow into the "grid" during the flood season. These waters will soak the soil inside the slope protection structure for a long time, making the soil soft and causing the water pressure inside the slope protection structure to rise sharply, thereby increasing the risk of damage to the slope protection structure.

[0005] In view of the above problems, it is urgent to make innovative design on the basis of the original water conservancy engineering flood prevention slope protection structure. SUMMARY

[0006] The technical scheme of the present application provides a solution significantly different from the prior art, which specifically aims to provide a water conservancy engineering flood prevention slope protection structure to solve the problem of the rapid rise of water level during the flood season causing the risk of collapse due to excessive water pressure in the slope protection structure.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a water conservancy engineering flood prevention slope protection structure, comprising a slope protection body, further comprising:

[0008] An adaptive closing mechanism arranged in an array combination on the outer wall of the slope protection body;

[0009] An auxiliary compression mechanism arranged in the adaptive closing mechanism;

[0010] The adaptive closing mechanism comprises a square layer body arranged equidistantly on the outer wall of the slope body, water inlets are arranged on both sides of the outer wall of the square layer body, and a floating block is movably arranged on the inner wall of the water inlet;

[0011] One side of the bottom of the inner wall of the square layer body is movably provided with a first shaft body, and the outer wall of the first shaft body is wound with a water retaining layer;

[0012] The auxiliary compression mechanism comprises a lifting block connected with one end of the water retaining layer, guide rails are arranged on both sides of the inner wall of the square layer body, and an extension rod is connected to the outer wall of the lifting block;

[0013] One end of the extension rod is connected with a connecting block, and the inner wall of the connecting block is clamped with a pressing layer;

[0015] The material of the pressing layer is a composite coiled material with certain longitudinal strength and can be rolled up.

[0016] Preferably, the top of the floating block is movably provided with a pressure top plate, and one side of the outer wall of the pressure top plate is connected with a sliding rod;

[0017] Both sides of the inner wall of the square layer body are provided with a sliding groove, and the diameter of the sliding groove of the square layer body is matched with the diameter of the sliding rod.

[0018] Preferably, the outer wall of the extension rod is surrounded by a spring, and one side of the outer wall of the connecting block is provided with a clamping rod;

[0019] The other side of the inner wall of the square layer body is movably provided with a second shaft body, and the pressing layer is wound on the outer wall of the second shaft body.

[0020] Preferably, the inner wall of the water inlet is hollow, and the diameter of the floating block is matched with the inner wall of the water inlet.

[0021] Preferably, the bottom of the inner wall of the square layer body is provided with a cavity, and the diameter of the cavity of the square layer body is matched with the diameters of the water retaining layer and the pressing layer.

[0022] Preferably, one end of the sliding rod is connected with one side of the outer wall of the pressure top plate, and the other end of the sliding rod is connected with one end of the water retaining layer.

[0023] Preferably, the three-dimensional view of the floating block is a rectangular parallelepiped, and the material of the floating block is plastic and hollow inside.

[0024] Preferably, the three-dimensional view of the clamping rod is a cylinder, and the diameter of the clamping rod is matched with the diameter of the inner wall of the guide rail.

[0028] 1. The water retaining layer can rise synchronously with the water level. In the flood season, the water level rises rapidly, and in the traditional slope protection structure, the water flow will quickly flow into the inside of the slope protection, impacting the soil and vegetation inside the slope protection. The setting of the water retaining layer can isolate the water flow outside the slope protection in the first time, although it cannot completely isolate the water flow, but can greatly delay the speed of the water flow into the slope protection, thereby improving the pressure bearing strength of the slope protection. Under the premise of not significantly sacrificing the original flexibility and drainage advantage of the slope protection, the anti-flood pressure bearing capacity and overall stability of the slope protection in extreme conditions are greatly improved, which provides a certain guarantee for the flood prevention safety of the water conservancy project, and also relieves the problem of rapid loss of soil erosion inside the slope protection. The present application can cope with the characteristics of synchronous change of form with the rising of water level in the flood season, not only improves the universality of the present application, but also ensures the protection efficiency of the present application.

[0029] 2. The auxiliary compression mechanism can press the vegetation inside the lattice layer body downward while the water retaining layer rises, so that the vegetation cannot affect the rising of the water retaining layer, and the pressing of the vegetation by the pressing layer is "flexible pressing", and the pressed vegetation can naturally recover and grow, continuing to play its ecological function of soil fixation and soil and water conservation. Under the condition of flood, the self-adaptive closing mechanism can be started smoothly without delay, the probability of action failure caused by natural factors is reduced to the minimum, and then the auxiliary compression mechanism improves the adaptability and immediate effect of the present application.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0042] Please refer to Figures 1 to 10 The present application provides a technical solution: a flood prevention slope structure for water conservancy projects, comprising a slope body 1, further comprising:

[0043] The adaptive closing mechanism 2 is arranged in an array combination on the outer wall of the slope body 1;

[0044] The auxiliary compression mechanism 3 is arranged inside the adaptive closing mechanism 2;

[0045] The adaptive closing mechanism 2 comprises square layer bodies 201 arranged in an equidistant array on the outer wall of the slope body 1, and water inlets 202 are formed on both sides of the outer wall of the square layer bodies 201, and the inner wall of the water inlet 202 movably has a floating block 203;

[0046] One side of the inner wall bottom of the square layer body 201 movably has a first shaft body 206, and the outer wall of the first shaft body 206 is wound with a water retaining layer 207;

[0047] The auxiliary pressing mechanism 3 includes a lifting block 301 connected to one end of the water-blocking layer 207, guide rails 306 are provided on both sides of the inner wall of the grid layer body 201, and a telescopic rod 302 is connected to the outer wall of the lifting block 301.

[0048] One end of the telescopic rod 302 is connected to a connecting block 304, and the inner wall of the connecting block 304 is engaged with a pressing layer 308;

[0049] The water-retaining layer 207 is made of oil-based canvas with certain waterproof and lateral strength.

[0050] The material of the pressing layer 308 is a composite roll material with certain longitudinal strength and rewindability.

[0051] In this embodiment, the water-retaining layer 207 can rise synchronously with the water level. During the flood season, the water level rises rapidly. In traditional slope protection structures, water will quickly rush into the slope, impacting the soil and vegetation inside. The water-retaining layer 207 can isolate the water flow outside the slope in the first instance. Although it cannot completely isolate the water flow, it can significantly slow down the speed at which the water flows into the slope, thereby improving the slope's bearing capacity. Thus, without significantly sacrificing the original flexibility and drainage advantages of the slope, it greatly enhances its flood resistance and overall stability under extreme conditions, providing a certain guarantee for the flood control safety of water conservancy projects.

[0052] A pressure plate 204 is movably installed on the top of the float 203, and a sliding rod 205 is connected to one side of the outer wall of the pressure plate 204;

[0053] The inner walls of the grid layer body 201 are provided with grooves on both sides, and the diameter of the grooves of the grid layer body 201 is adapted to the diameter of the slide rod 205.

[0054] In this embodiment, the auxiliary pressing mechanism 3 can press down the vegetation inside the grid layer body 201 while the water-retaining layer 207 rises, so that the vegetation cannot affect the rise of the water-retaining layer 207. Moreover, the pressing layer 308 presses down the vegetation in a "soft pressing" manner, and the pressed vegetation can naturally recover and continue to play its ecological function of root system soil fixation and water and soil conservation. This ensures that the adaptive closing mechanism 2 can be started smoothly without delay in the event of flood, minimizing the probability of action failure caused by natural factors. In this way, the auxiliary pressing mechanism 3 improves the adaptability and immediate effect of the present invention.

[0055] A spring 303 is arranged around the outer wall of the telescopic rod 302, and a locking rod 305 is provided on one side of the outer wall of the connecting block 304;

[0056] A second shaft 307 is movably disposed on the other side of the inner wall of the grid layer body 201, and a pressing layer 308 is wound around the outer wall of the second shaft 307.

[0057] In this embodiment, when the water-blocking layer 207 is pulled upward, it will drive the lifting block 301 to move synchronously. When the lifting block 301 moves upward, the connecting block 304 connected to one end of the telescopic rod 302 is provided with a locking rod 305 on its outer wall. The locking rod 305 will move along the inner wall of the guide rail 306. When the locking rod 305 slides, it will drive the telescopic rod 302 and the spring 303 to stretch. Since the outer wall of the connecting block 304 is engaged with one end of the pressing layer 308, the pressing layer 308 will move synchronously when the connecting block 304 moves upward.

[0058] The inner wall of the inlet 202 is hollow, and the diameter of the float 203 is adapted to the inner wall of the inlet 202.

[0059] In this embodiment, when water surges to the outer wall of the grid layer body 201, it flows into the water inlets 202 opened on both sides of the outer wall of the grid layer body 201. As the water gradually flows in, the water level inside the water inlets 202 will rise synchronously with the external water level. After the water level rises, the float 203 will float on the water surface and rise with the water level, generating a certain buoyancy. After the float 203 rises to a certain position, the float 203 will push against the bottom of the outer wall of the pressure plate 204. As the float 203 continues to rise, it will lift the pressure plate 204 and float upward. When the pressure plate 204 moves upward, it will drive the sliding rod 205 connected to its outer wall to move synchronously.

[0060] The bottom of the inner wall of the grid layer body 201 is provided with a cavity, and the diameter of the cavity of the grid layer body 201 is adapted to the diameter of the water-blocking layer 207 and the pressing layer 308.

[0061] In this embodiment, after the float 203 rises to a certain position, it will push against the bottom of the outer wall of the pressure plate 204. As the float 203 continues to rise, it will lift the pressure plate 204 and cause it to float upwards. When the pressure plate 204 moves upwards, it will drive the sliding rod 205 connected to its outer wall to move synchronously. When the sliding rod 205 moves, it will drive the water-blocking layer 207 to move synchronously. When the water-blocking layer 207 moves upwards, it will drive the first shaft 206 to rotate. At this time, the water-blocking layer 207 will gradually move from the bottom of the inner wall of the grid layer body 201. The cavity is pulled upwards, and the height of the pull is controlled synchronously with the rise of the water level. If the water level rises to the top of the outer wall of the grid layer body 201, the water-retaining layer 207 will completely cover the interior of the grid layer body 201 to ensure that the water will not rush into the soil inside the slope protection body 1 after the rise. (The water-retaining layer 207 and the pressing layer 308 can "extend" from the cavity of the grid layer body 201 synchronously when the water level rises. Both the water-retaining layer 207 and the pressing layer 308 are made of materials with both "flexibility" and "rigidity" to respond to the rapid rise of water level during the flood season in real time.)

[0062] One end of the slide rod 205 is connected to one side of the outer wall of the pressure plate 204, and the other end of the slide rod 205 is connected to one end of the water-blocking layer 207.

[0063] In this embodiment, after the float 203 rises to a certain position, the float 203 will push against the bottom of the outer wall of the pressure plate 204. As the float 203 continues to rise, it will lift the pressure plate 204 and make it float upward. When the pressure plate 204 moves upward, it will drive the sliding rod 205 connected to its outer wall to move synchronously. When the sliding rod 205 moves, it will drive the water-blocking layer 207 to move synchronously. When the water-blocking layer 207 moves upward, it will drive the first shaft 206 to rotate. (When the sliding rod 205 moves, it will pull the water-blocking layer 207 to move synchronously, which means that the water-blocking layer 207 can move synchronously with the rise of the water level, ensuring the real-time performance of the water-blocking layer 207.)

[0064] The three-dimensional view of float 203 is cuboid. Float 203 is made of plastic and is hollow inside.

[0065] In this embodiment, after the water level rises, the float 203 will float on the water surface and generate a certain buoyancy as the water level rises. After the float 203 rises to a certain position, it will push against the bottom of the outer wall of the pressure plate 204. As the float 203 continues to rise, it will lift the pressure plate 204 and float upward. When the pressure plate 204 moves upward, it will drive the sliding rod 205 connected to its outer wall to move synchronously. (The float 203 can provide "buoyancy" as the water level rises. The "buoyancy" can drive the adaptive closing mechanism 2 to be triggered. And because the water level rises quickly and the water pressure is high during the flood season, the "buoyancy" generated by the float 203 can support the rise of the water-retaining layer 207 and ensure that the water-retaining layer 207 can rise synchronously with the water level.)

[0066] The three-dimensional view of the lever 305 is cylindrical, and the diameter of the lever 305 is matched with the diameter of the inner wall of the guide rail 306.

[0067] In this embodiment, a locking rod 305 is provided on the outer wall, and the locking rod 305 moves along the inner wall of the guide rail 306. When the locking rod 305 slides, it will drive the telescopic rod 302 and the spring 303 to stretch. Since the outer wall of the connecting block 304 is engaged with one end of the pressing layer 308, the pressing layer 308 will move synchronously when the connecting block 304 moves upward. Since the pressing layer 308 is made of composite roll material, its material can withstand longitudinal pressure. Since the direction of movement of the pressing layer 308 is synchronized with the direction of movement of the connecting block 304, the pressing layer 308 will present a movement trajectory that moves diagonally upward (the locking rod 305 can slide along the inner wall of the guide rail 306, and the guide rail 306 is inclined, which means that the movement trajectory of the locking rod 305 is also inclined, so that the movement trajectory of the pressing layer 308 is inclined, thus gradually pressing down the vegetation).

[0068] The three-dimensional view of the grid layer body 201 is a cube, and the material of the grid layer body 201 is high-density polyethylene.

[0069] In this embodiment, when the flood season arrives, the water level gradually rises. At this time, the water flow gradually surges to the outer wall of the grid layer body 201. As the water reaches the outer wall of the grid layer body 201, it flows into the inlets 202 opened on both sides of the outer wall. After the water gradually flows in, the water level inside the inlets 202 also rises synchronously with the external water level. After the water level rises, the float 203 floats on the water surface and rises with the water level, generating a certain buoyancy. After the float 203 rises to a certain position, it floats... Block 203 will reach the bottom of the outer wall of the pressure plate 204, and as the floating block 203 continues to rise (the high-density polyethylene material has extremely strong chemical corrosion resistance, and can resist the damage of acid and alkali substances, microbial erosion and freeze-thaw cycles in the water for a long time, ensuring the long service life of the slope protection structure in harsh environments, and has a certain strength and toughness, so that the grid layer body 201 can effectively resist the deformation caused by other problems, and achieve overall flexible adaptation through the hinge between the blocks to avoid structural fracture).

[0070] One side of the outer wall of the lifting block 301 is parallel to one side of the inner wall of the grid layer body 201, and the lifting block 301 is movably connected to one side of the inner wall of the grid layer body 201.

[0071] In this embodiment, when the water-retaining layer 207 is pulled upward, it may be blocked by vegetation or generate resistance, causing the water-retaining layer 207 to undergo slight deformation under longitudinal pressure. It is difficult to cope with the longitudinal pressure generated by the impact of rising water level on the outer wall of the water-retaining layer 207. At the same time, when the water-retaining layer 207 is pulled upward, it will drive the lifting block 301 to move synchronously. When the lifting block 301 moves upward, the connecting block 304 connected to one end of the telescopic rod 302 is equipped with a locking rod 305 on its outer wall. The locking rod 305 will move along the inner wall of the guide rail 306. When the locking rod 305 slides, it will drive the telescopic rod 302 and the spring 303 to stretch. Since the outer wall of the connecting block 304 is engaged with one end of the pressing layer 308, the pressing layer 308 will move synchronously when the connecting block 304 moves upward.

[0072] Working principle: When using this type of flood control slope protection structure in water conservancy projects, such as Figure 1 , Figure 3 and Figure 4 Before the flood season arrives, the structures are in their initial state. When the flood season arrives:

[0073] First, the water level will gradually rise, and the water will gradually flow to the outer wall of the grid layer body 201. When the water flows to the outer wall of the grid layer body 201, it will flow into the water inlets 202 opened on both sides of the outer wall of the grid layer body 201. After the water gradually flows in, the water level inside the water inlets 202 will also rise synchronously with the external water level. After the water level rises, the float 203 will float on the water surface and rise with the water level, generating a certain buoyancy. After the float 203 rises to a certain position, the float 203 will push against the bottom of the outer wall of the pressure plate 204. As the float 203 continues to rise, it will lift the pressure plate 204 and make it float upward. When the pressure plate 204 moves upward, it will bring... The sliding rod 205 connected to the outer wall moves synchronously. When the sliding rod 205 moves, it will drive the water-retaining layer 207 to move synchronously. When the water-retaining layer 207 moves upward, it will drive the first shaft 206 to rotate. At this time, the water-retaining layer 207 will gradually be pulled up from the cavity opened at the bottom of the inner wall of the grid layer body 201. The height of the pull-up will be controlled synchronously with the rise of the water level. If the water level rises to the top of the outer wall of the grid layer body 201, the water-retaining layer 207 will completely cover the interior of the grid layer body 201 to ensure that the water will not rush into the soil inside the slope protection body 1 after the rise, but will flow in slowly. This can reduce the problem of excessive water pressure caused by the rapid rise of the water level.

[0074] However, the upward movement of the water-retaining layer 207 is not unobstructed. The interior of the grid layer 201 contains soil and vegetation. When the water-retaining layer 207 is pulled upwards, it may be blocked or resisted by the vegetation, causing slight deformation due to longitudinal pressure. This makes it difficult to cope with the longitudinal pressure generated by the impact of rising water levels on the outer wall of the water-retaining layer 207. Simultaneously, the upward movement of the water-retaining layer 207 will cause the lifting block 301 to move synchronously. When the lifting block 301 moves upwards, the connecting block 304 connected to one end of the telescopic rod 302 has a locking rod 305 on its outer wall. The locking rod 305 moves along the inner wall of the guide rail 306. When the locking rod 305 slides, it will cause the telescopic rod 302 and the spring 303 to stretch. And because... The outer wall of the connecting block 304 is engaged with one end of the pressing layer 308. When the connecting block 304 moves upward, the pressing layer 308 moves synchronously. Since the pressing layer 308 is made of composite roll material, it can withstand longitudinal pressure. And since the direction of movement of the pressing layer 308 is synchronized with the direction of movement of the connecting block 304, the pressing layer 308 will exhibit a movement trajectory that moves diagonally upward. When the pressing layer 308 moves, it can bend or lower some vegetation inside the grid layer body 201, so that the vegetation cannot affect the upward movement trajectory of the water-retaining layer 207. This improves the ability of the invention to cope with rising water levels during the flood season and the "morphological change" that occurs synchronously with the water level. This not only improves the versatility of the invention, but also ensures the immediate protection efficiency of the invention.

[0075] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
