Description

Technical Field

[0001] This invention patent relates to the technical field of flood control structures. Specifically, it relates to a diversified flood control structure that takes into account both flood control and ecology. Background Art

[0002] In recent years, ecological flood control technologies have gradually emerged, providing habitat space for aquatic organisms such as fish. There are various technical modes such as vertical and inclined types, each with its own advantages and disadvantages. For example, the vertical revetment has a single form and poor hydrophilicity; the inclined revetment has a larger space requirement, but its hydrophilicity and safety are better than those of the vertical revetment.

[0003] In the prior art, projects such as flood control dikes mostly adopt rigid structures such as concrete retaining walls or grouted rubble masonry. These structures are strong but lack ecological space, seriously damaging the habitat environment of fish and other aquatic organisms and impairing the health of the river ecosystem.

[0004] In addition, in the face of the increasing number of extreme flood events caused by climate change and changes in river hydrological conditions, the existing ecological flood control structures are insufficient in adaptability. Often, under the impact of strong water flows, problems such as damage, deformation, or loss of ecological functions will occur, and it is impossible to effectively balance flood control safety and ecological protection. Summary of the Invention

[0005] The purpose of the present invention is to provide a diversified flood control structure that takes into account both flood control and ecology, aiming to solve the problem in the prior art that it is difficult to balance the flood control function and ecological protection of flood control structures.

[0006] The present invention is implemented as follows. It includes a dike arranged on the outer periphery of a reservoir. The dike has a water-receiving area facing the reservoir. The water-receiving area has a deviation inclined portion. Along the upward direction of the water-receiving area, the inclined portion is arranged to deviate from the reservoir.

[0007] The inclined portion is provided with a plurality of upper ecological grooves arranged in a recessed manner and for aquatic organisms such as fish to inhabit. The outer end of the upper ecological groove penetrates through the inclined portion to form an ecological opening.

The interval area is provided with a convex structure for buffering the impact of water flow.

[0008] The ecological opening is covered with an elastic net layer. The outer periphery of the elastic net layer is fixedly connected to the inclined portion. The elastic net layer is arranged in a relaxed state at the ecological opening. Along with the flow and impact of water, the elastic net layer deforms flexibly synchronously. A plurality of elastic net holes are provided in the elastic net layer.

[0009] A plurality of platform parts are provided on the water-facing area. Along the direction from top to bottom of the water-facing area, the plurality of platform parts are arranged in sequence, and the plurality of platform parts are arranged below the inclined part; the top of the platform part is recessed downward to form a lower ecological trough for aquatic organisms such as fish to inhabit.

[0010] Further, the convex structure includes a floating cylinder that is suspended in the water and rotatably arranged. The floating cylinder is movably arranged in the interval area.

[0011] Further, a central axis protrudes in the interval area. The floating cylinder is movably sleeved on the central axis. When the floating cylinder is impacted by the flow of water, the floating cylinder rotates around the central axis.

[0012] Further, two elastic blocks are sleeved on the central axis. The central axis has an intermediate section located between the two elastic blocks. The floating cylinder is movably sleeved on the intermediate section, and the length of the intermediate section is greater than the length of the floating cylinder; when the floating cylinder is impacted by the flow of water, the floating cylinder rotates around the central axis, and the floating cylinder synchronously reciprocates along the intermediate section.

[0013] Further, a plurality of spiral holes are provided in the floating cylinder. The plurality of spiral holes are arranged at intervals along the circumferential direction of the floating cylinder; the inner end of the spiral hole extends spirally towards the middle of the floating cylinder, and the outer end of the spiral hole penetrates through the outer circumference of the floating cylinder to form an outer peripheral opening;

[0014] When the floating cylinder is impacted by the flow of water, the water impacts the spiral holes through the outer peripheral opening, driving the floating cylinder to rotate around the central axis.

[0015] Further, an isolation net layer is suspended on the inclined part. The isolation net layer is respectively connected to a plurality of central axes. The isolation net layer is arranged above the plurality of floating cylinders. A plurality of isolation net holes are provided in the isolation net layer.

[0016] Further, a planting tray is sleeved in the isolation net hole. Nutrient soil is provided in the planting tray. Aquatic plants are planted on the planting tray; the outer periphery of the planting tray is snap-connected to the isolation net layer, and the plurality of planting trays are arranged at intervals on the isolation net layer.

[0017] Further, a fixing rod is inserted through the planting tray. The upper part of the fixing rod is embedded in the planting tray. The lower part of the fixing rod penetrates into the upper ecological trough and is embedded in the dam, and is fixedly connected to the dam.

[0019] Furthermore, the lower part of the outer periphery of the lower ecological tank is recessed outward to form an outer peripheral groove, and the outer peripheral groove is arranged along the outer periphery of the lower ecological tank; a circumferentially arranged positioning ring is connected to the outer periphery of the wire mesh, and the positioning ring is embedded in the outer peripheral groove and fixed in the outer peripheral groove;

[0020] A middle block arranged in a protruding manner is provided in the middle of the lower ecological tank. The middle block passes through the wire mesh and is fixedly connected to the middle of the wire mesh.

[0022] At the same time, the ecological opening of the upper ecological tank covers an elastic net layer, which can synchronously deform flexibly under the impact of water flow. This not only ensures the openness of the ecological tank, facilitates the entry and exit of fish, but also can buffer the impact of water flow on the organisms in the ecological tank to a certain extent, protect the organisms inhabiting therein, improve the stability and adaptability of the ecological structure, and effectively take into account flood control safety and ecological protection;

[0031] Refer to Figures 1-3 As shown, it is a preferred embodiment provided by the present invention.

[0032] A diversified flood control structure that takes into account flood control and ecology, including a dam 100 provided on the outer periphery of the reservoir. The dam 100 has a water-facing area 101 facing the reservoir. The water-facing area 101 has an inclined part 102 facing away from it. Along the upward direction of the water-facing area 101 from bottom to top, the inclined part 102 is arranged obliquely away from the reservoir;

[0033] The inclined part 102 is provided with a plurality of upper ecological troughs 200 arranged in depressions and for aquatic organisms such as fish to inhabit. The outer end of the upper ecological trough 200 penetrates through the inclined part 102 to form an ecological opening 201. The inner end of the upper ecological trough 200 bends and extends inward, showing a curved arrangement; a spacing area 202 is formed between adjacent upper ecological troughs 200, and the spacing area 202 is provided with a convex structure for buffering the impact of water flow;

[0034] The ecological opening 201 is covered with an elastic mesh layer 203. The outer periphery of the elastic mesh layer 203 is fixedly connected to the inclined portion 102. The elastic mesh layer 203 is arranged in a relaxed state at the ecological opening 201. With the impact of the flowing water, the elastic mesh layer 203 synchronously deforms flexibly. There are a plurality of elastic mesh holes in the elastic mesh layer 203;

[0035] There are a plurality of platform portions 103 on the water-facing area 101. Along the direction from top to bottom of the water-facing area 101, the plurality of platform portions 103 are arranged in sequence, and the plurality of platform portions 103 are arranged below the inclined portion 102; the top of the platform portion 103 is recessed downward to form a lower ecological groove 400 for aquatic organisms such as fish to inhabit.

[0036] The above-mentioned diversified flood control structure that takes into account flood control and ecology provides diverse habitats for aquatic organisms such as fish by setting an upper ecological groove 200 and a lower ecological groove 400 on the inclined portion 102 of the water-facing area 101 of the dam 100, effectively improves the living environment of aquatic organisms, solves the problem of limited ecological space of the flood control structure, and is conducive to maintaining and enhancing the biodiversity of the river ecosystem;

[0037] At the same time, the ecological opening 201 of the upper ecological groove 200 is covered with an elastic mesh layer 203. The elastic mesh layer 203 can synchronously deform flexibly under the impact of water flow, which not only ensures the openness of the ecological groove for fish to enter and exit, but also can buffer the impact of water flow on the organisms in the ecological groove to a certain extent, protect the organisms inhabiting therein, improve the stability and adaptability of the ecological structure, and effectively takes into account flood control safety and ecological protection;

[0038] In addition, the raised structure arranged in the spaced area 202 further enhances the buffering capacity of the dam 100 against the impact of water flow, helps to reduce the erosion and damage of the flood on the dam 100, ensures the stability of the flood control structure, and thus better realizes the goal of ecological protection on the basis of ensuring the flood control function, overcoming the defect that it is difficult for the flood control structure in the prior art to meet the requirements of flood control and ecological protection at the same time.

[0039] In this embodiment, the raised structure includes a floating cylinder 300 suspended in water and arranged to rotate. The floating cylinder 300 is movably arranged in the spaced area 202.

[0040] Through the rotation function of the floating cylinder 300, the impact force of the water flow can be converted into its own rotational movement, reducing the direct impact of the water flow on the dam 100. Thus, while ensuring the structural stability and flood control safety of the dam 100, aquatic organisms such as fish can swim freely around the floating cylinder 300 and use the weak water flow changes generated by the rotation of the floating cylinder 300 to find food and habitats, providing more natural and dynamic living conditions for organisms and meeting the requirements of taking into account flood control functions and ecological protection.

[0041] In this embodiment, a central shaft 301 protrudes from the spacing area 202, and the floating cylinder 300 is movably sleeved on the central shaft 301. When the floating cylinder 300 is impacted by the flowing water, the floating cylinder 300 rotates around the central shaft 301.

[0042] In this way, the central shaft 301 provides a stable rotation center for the floating cylinder 300, enabling the floating cylinder 300 to maintain a stable rotation state when impacted by water flows of different intensities, ensuring that the floating cylinder 300 will not shift or be damaged under the long-term action of water flow.

[0043] For aquatic organisms such as fish, a stable rotating environment of the floating cylinder 300 means that they can inhabit there without being disturbed by drastic changes in water flow, and can adapt to the natural fluctuations of water flow and maintain their normal living habits and behavior patterns like in natural rivers, further enhancing the ecological compatibility of the flood control structure.

[0044] In this embodiment, two elastic blocks 302 are sleeved on the central shaft 301. The central shaft 301 has an intermediate section 303 located between the two elastic blocks 302. The floating cylinder 300 is movably sleeved on the intermediate section 303, and the length of the intermediate section 303 is greater than the length of the floating cylinder 300. When the floating cylinder 300 is impacted by the flowing water, the floating cylinder 300 rotates around the central shaft 301, and the floating cylinder 300 synchronously reciprocates along the intermediate section 303.

[0045] When the water flow impacts the floating cylinder 300, the multi-dimensional movement mode of the floating cylinder 300 can more effectively absorb and disperse the impact energy of the water flow, further reducing the pressure on the dam 100 and improving the durability and reliability of the flood control structure.

[0046] For aquatic organisms such as fish, the elastic movement simulates the natural fluctuations and changes of water flow in natural rivers, providing a more natural habitat environment for the organisms, enabling them to better adapt and survive in the changing water flow, and enhancing the ecological function and biocompatibility of the flood control structure.

[0047] In this embodiment, a plurality of spiral holes 304 are provided in the floating cylinder 300. The plurality of spiral holes 304 are arranged at intervals along the circumferential direction of the floating cylinder 300. The inner end of the spiral hole 304 spirally extends towards the middle of the floating cylinder 300, and the outer end of the spiral hole 304 penetrates through the outer periphery of the floating cylinder 300 to form an outer peripheral opening 305.

[0048] When the floating cylinder 300 is impacted by the flowing water, the water flow impacts the spiral holes 304 through the outer peripheral opening 305, driving the floating cylinder 300 to rotate around the central shaft 301.

[0049] In this way, due to the connection between the water flow and the spiral holes 304 and the floating cylinders 300, a self-driven rotation mode is generated, which not only requires no external energy input, but also can automatically adjust the rotation speed and direction according to the intensity and direction of the water flow, thus more effectively buffering the water flow impact and improving the adaptability and flood control effect of the flood control structure;

[0050] For aquatic organisms such as fish, this dynamic water flow environment simulates the water flow changes in natural rivers, provides richer and more diverse foraging, breeding and inhabiting conditions for organisms, promotes the natural behaviors and ecological processes of organisms, and significantly enhances the ecological value of the flood control structure and the function of protecting biological diversity.

[0051] In this embodiment, an isolation net layer 104 is arranged on the inclined part 102 in a suspended manner. The isolation net layer 104 is respectively connected to a plurality of central shafts 301. The isolation net layer 104 is arranged above the plurality of floating cylinders 300, and a plurality of isolation net holes are provided in the isolation net layer 104.

[0052] Through the connection with the central shaft 301, the isolation net layer 104 separates the plurality of floating cylinders 300, avoiding mutual collision and interference between the floating cylinders 300, ensuring that each floating cylinder 300 can rotate independently and stably under the action of water flow, and the isolation net holes can accommodate small aquatic organisms to enter and inhabit, increasing the diversity of biological habitats;

[0053] In addition, the isolation net layer 104 can block large debris from entering the lower ecological tank 400, preventing debris accumulation from affecting the normal flow of water and the living environment of organisms, and maintaining the ecological function and water quality condition of the ecological tank.

[0054] In this embodiment, a planting tray 105 is sleeved in the isolation net holes. The planting tray 105 is provided with nutrient soil, and aquatic plants 106 are planted on the planting tray 105; the outer periphery of the planting tray 105 is buckled and connected to the isolation net layer 104, and a plurality of planting trays 105 are arranged at intervals on the isolation net layer 104.

[0055] In this way, the aquatic plants 106 absorb nutrients in the water through their roots, thus playing a role in purifying the water quality and improving the ecological environment of the water body. At the same time, the leaves and stems of the aquatic plants 106 provide rich food sources and habitats for aquatic animals, increasing the biomass and species diversity of the ecosystem. In addition, the buckling connection method between the planting tray 105 and the isolation net layer 104 ensures the stability and safety of the planting tray 105, enabling it to maintain its position under the impact of water flow and continuously play its ecological function.

[0056] In this embodiment, a fixing rod 107 is inserted through the planting tray 105. The upper part of the fixing rod 107 is embedded in the planting tray 105, and the lower part of the fixing rod 107 penetrates into the upper ecological tank 200 and is embedded in the dam 100, being fixedly connected to the dam 100.

[0057] By fixedly connecting the fixing rod 107 to the dam 100, a stable support system is formed, ensuring that the planting tray 105 will not be displaced, tilted or damaged under the influence of external forces such as water flow impact, wind and wave action or human activities, thus guaranteeing the normal growth of the aquatic plants 106 and the continuous exertion of the ecological functions.

[0058] In this embodiment, the bottom of the lower ecological tank 400 is recessed downward to form a plurality of honeycomb-shaped bottom ecological tanks 401. A plurality of stones 402 are laid in the lower ecological tank 400. The plurality of stones 402 are connected by a wire mesh 403 to form an integral structure, and adjacent stones 402 are arranged at intervals. A plurality of honeycomb holes are provided in the stones 402.

[0059] The recessed bottom ecological tank 401 increases the depth and spatial level of the ecological tank, providing diverse habitats for aquatic organisms such as fish of different species and living habits. The laying of the stones 402 simulates the riverbed environment in natural rivers. In particular, the intervals and honeycomb holes between the stones 402 provide ideal habitat spaces for small fish and other aquatic organisms, which is beneficial to their survival and reproduction;

[0060] In addition, the intervals and honeycomb holes between the stones 402 are also conducive to the penetration and exchange of water flow, promoting the circulation of water bodies and the supplement of oxygen, improving the water quality conditions, thereby enhancing the ecological value of the flood control structure and the ability to protect biodiversity.

[0061] In this embodiment, the lower part of the outer periphery of the lower ecological tank 400 is recessed outward to form an outer peripheral groove 404. The outer peripheral groove 404 is arranged around the outer periphery of the lower ecological tank 400; the outer periphery of the wire mesh 403 is connected with an annular positioning ring 405, and the positioning ring 405 is embedded in the outer peripheral groove 404 and fixed in the outer peripheral groove 404;

[0062] A centrally raised middle block 406 is provided in the middle of the lower ecological tank 400. The middle block 406 passes through the wire mesh 403 and is fixedly connected to the middle of the wire mesh 403.

[0063] By the combined use of the outer peripheral groove 404 and the positioning ring 405, the wire mesh 403 and the stone 402 structure will not be displaced or deformed when subjected to water flow impact or other external forces. The setting of the middle block 406 further enhances the connection strength between the wire mesh 403 and the lower ecological tank 400 and forms an integral structure, improving the stability and impact resistance of the entire ecological structure;

[0064] Enable the flood control structure to ensure the survival of organisms and the stability of the ecosystem even under severe flood conditions, effectively taking into account the dual needs of flood control and ecological protection, and achieving the harmonious coexistence of flood control projects and the ecological environment.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
