Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering and ecological restoration technology, and in particular to an ecological slope protection method for water conservancy projects. Background Technology

[0002] Slope protection technology in water conservancy projects has evolved from traditional rigid slope protection to flexible slope protection. In recent years, with the increasing awareness of ecological and environmental protection, ecological slope protection technology has gradually become a research hotspot. Ecological slope protection not only needs to meet the mechanical requirements of slope stability, but also needs to take into account the ecological restoration function, promote plant growth and aquatic organism habitat. At present, there are a variety of ecological slope protection technologies at home and abroad, such as vegetated concrete, ecological bags, and three-dimensional vegetation nets. However, these technologies still have certain limitations in terms of long-term stability, construction convenience and cost control.

[0003] A search revealed a Chinese publication (CN222500105U) disclosing an ecological slope protection system for water conservancy projects. The system includes a slope body with a cavity at its lower end and a through-groove at its front end, the cavity at the bottom of which is interconnected. A first nylon mesh is laid on the slope's inclined surface, and a quartz sand layer is laid on the surface of the first nylon mesh. This system, with its first nylon mesh, quartz sand layer, and soil layer, allows water to be filtered through the soil layer, second nylon mesh, quartz sand layer, first nylon mesh, and filter plate during rainwater or artificial irrigation of grasses planted on the slope. The water is then retained in the cavity at the lower end of the slope, reducing water loss. Furthermore, the pumping mechanism facilitates the reuse of irrigation water, further conserving water and reducing labor costs.

[0004] The patent description mentions that "the filtered water remains inside the cavity at the lower end of the slope, which can reduce water loss." However, it cannot fix the ecological module. Without fixation, the ecological module is prone to displacement or even detachment under the influence of water flow, wind, or other external forces. This will damage the overall structure of the slope protection, causing gaps or unevenness, reducing its protective effect on the slope, and leading to soil exposure and increasing the risk of soil erosion. In response to the above problems, an ecological slope protection method for water conservancy projects is proposed. Utility Model Content

[0005] This utility model proposes an ecological slope protection method for water conservancy projects, aiming to improve the problem that some existing devices in water conservancy projects cannot connect and fix ecological modules for ecological slope protection.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An ecological slope protection system for a water conservancy project includes a slope soil layer, with multiple ecological modules fixedly connected to the top of the slope soil layer, an anti-scouring net fixedly connected inside the ecological modules, anchor rods fixedly connected to the left and right sides of the slope soil layer, nuts threaded onto the outside of the anchor rods, fixing mechanisms fixedly connected to the left and right sides of the outside of the ecological modules, and disassembly and assembly mechanisms slidably connected to the top left and right sides of the ecological modules.

[0008] The fixing mechanism includes a connector, which is externally fixedly connected to the left and right sides of the ecological module. A mounting bracket is externally fixedly connected to the connector, and a rotating shaft is internally fixedly connected to the mounting bracket. A rotating plate is rotatably connected to the external side of the rotating shaft, and a reset component is externally fixedly connected to the external side of the rotating plate. A positioning rod is externally fixedly connected to the external side of the rotating plate.

[0009] The above solution involves connecting the mounting bracket to both sides of the ecological module, with a rotating shaft inside the bracket allowing the rotating plate to rotate flexibly. The reset component ensures that the plate returns to its original position in a timely manner. The positioning rod on the rotating plate can be precisely embedded into a specific position in the slope soil layer, tightly fixing the ecological module and effectively improving the overall stability of the slope protection and resisting water erosion.

[0010] As a further description of the above technical solution:

[0011] The reset assembly includes a telescopic rod, which is fixedly connected to the outside of the rotating plate, and a reset spring is sleeved on the outside of the telescopic rod.

[0012] The above solution involves a telescopic rod securely connected to the outside of the rotating plate. The external reset spring is highly elastic. When the rotating plate is rotated by an external force, the telescopic rod extends and retracts accordingly, compressing and storing energy in the reset spring. When the external force is removed, the spring instantly releases its energy, using the telescopic rod to push the rotating plate back into position quickly, ensuring the positioning rod is always ready to maintain the stability of the slope protection structure.

[0013] As a further description of the above technical solution:

[0014] The disassembly and assembly mechanism includes a sliding rod, which is slidably connected to the left and right sides of the outside of the ecological module. A connecting frame is fixedly connected to the bottom of the sliding rod. A rotating plate is rotatably connected to the outside of the connecting frame. A connecting frame is rotatably connected to the other end of the rotating plate. A sliding latch is fixedly connected to the bottom of the connecting frame.

[0015] With the above solution, the sliding rod can slide smoothly on both sides of the ecological module, and the bottom connecting frame can rotate flexibly, driving the rotating plate to open and close. The sliding clamp on the connecting frame at the other end of the rotating plate can accurately lock or release adjacent components, making module assembly easy during construction and disassembly convenient during maintenance, improving project efficiency and ensuring the long-term operation of the slope protection.

[0016] As a further description of the above technical solution:

[0017] The ecological module is internally fixedly connected to a telescopic rod two, and a tension spring is sleeved on the outside of the telescopic rod two.

[0018] Through the above scheme: the second telescopic rod is firmly fixed inside the ecological module, providing certain support and guidance for the structure. The tension spring sleeved on its outside has excellent elasticity. When the ecological module is subjected to external forces such as water flow impact and vibration, the second telescopic rod can extend and retract within a certain range, and the tension spring will stretch or compress accordingly, thereby buffering and dispersing external forces, protecting the integrity of the ecological module structure, extending its service life, and ensuring the stable performance of the ecological slope protection function.

[0019] As a further description of the above technical solution:

[0020] The anti-erosion net has slots on both the left and right sides of its exterior, and the outer side of the sliding rod is engaged with the slots on the exterior of the anti-erosion net.

[0021] The above solution involves carefully designed slots on both sides of the scour net to precisely match the sliding rods in the disassembly and assembly mechanism. During installation, simply slide the connecting bracket to allow the sliding rods to securely engage in the slots, quickly fixing the scour net and enhancing the slope's resistance to scour. During maintenance, the net can be easily disassembled by reversing the operation, making it efficient, convenient, and ensuring the slope protection performance.

[0022] As a further description of the above technical solution:

[0023] The rotating plate is rotatably connected to the outside of the mounting frame, and the positioning rod is rotatably connected to the outside of the mounting frame.

[0024] The above solution allows the rotating plate to rotate flexibly via the mounting frame. The connection between the rotating plate and the external mounting frame ensures smooth rotation and provides a basis for the operation of the positioning rod. The positioning rod is also rotatably connected to the external mounting frame. When the rotating plate rotates to the appropriate angle, the positioning rod can be embedded into the slope soil layer, providing a reliable anchor point for the ecological module, greatly enhancing the overall stability of the slope protection and effectively resisting water flow impact and soil erosion.

[0025] As a further description of the above technical solution:

[0026] The ecological module has multiple pipes fixedly connected to its external front side, and a soil layer is set inside the ecological module.

[0027] The above scheme involves multiple neatly fixed pipes on the front side of the module, which perform important functions such as drainage and irrigation, effectively regulating the moisture status of the slope. The module is filled with a soil layer, which not only provides the necessary substrate for vegetation growth, but also uses the vegetation root system to reinforce the soil, enhance the slope's resistance to erosion, and achieve harmonious coexistence between water conservancy projects and the ecological environment.

[0028] As a further description of the above technical solution:

[0029] One end of the tension spring is fixedly connected to the outside of the sliding lever, and the other end of the tension spring is fixedly connected to the inside of the ecological module.

[0030] Through the above scheme, the setting of the tension spring is crucial. One end is firmly connected to the outside of the sliding rod, and the other end is rooted inside the ecological module. When the anti-scour net is impacted by water flow and shakes, the sliding rod moves accordingly, and the tension spring will extend and retract. It uses elastic potential energy to buffer the impact force, ensuring that the anti-scour net is always closely connected to the ecological module, strengthening the overall anti-scour performance of the slope and protecting the stability of the slope.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, by pressing the rotating plate, the rotating plate can compress the telescopic rod, thereby causing the return spring to deform. By placing the ecological module outside the anchor rod, releasing the rotating plate causes the return spring to rebound, which in turn allows the rotating plate to drive the positioning rod to lock tightly against the outside of the anchor rod, thus fixing the ecological module.

[0033] 2. In this utility model, by loosening the sliding rod, the sliding rod causes the connecting frame to rotate through the rotating plate via the connecting frame, which in turn enables the connecting frame to drive the sliding clamp rod to slide inside the ecological module, causing the tension spring to rebound, thereby enabling the sliding clamp rod to lock with the anti-erosion net, thus realizing the disassembly and assembly of the anti-erosion net.

[0041] 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.

[0042] Reference Figures 1 to 3This utility model provides an embodiment of an ecological slope protection system for a water conservancy project, comprising a slope soil layer 1, which forms the foundation of the entire ecological slope protection system. The slope soil layer 1 is a naturally formed or artificially modified slope soil layer 5. The slope of the slope soil layer 1 is determined according to the specific requirements of the water conservancy project and the terrain conditions. Multiple ecological modules 2 are fixedly connected to the outer top of the slope soil layer 1. Each ecological module 2 has multiple planting holes or planting troughs for planting plants. These plants can help conserve water and soil and beautify the environment. The ecological modules 2 are also fixedly connected to erosion-resistant structures. The function of the scour net 3 is to prevent soil erosion within the ecological module 2 caused by rainwater erosion, while also providing support for plant roots and promoting plant growth. Anchor rods 6 are fixedly connected to the left and right sides of the outer slope soil layer 1. One end of the anchor rod 6 penetrates into the slope soil layer 1 and is tightly bonded to the soil layer through grouting, while the other end protrudes from the surface of the slope soil layer 1 for installing nuts 7. Nuts 7 are threaded onto the external surface of the anchor rod 6. Tightening the nuts 7 generates preload on the anchor rod 6, enhancing the stability of the slope soil layer 1 and preventing slope landslides. The outer surface of the ecological module 2... Fixing mechanisms 8 are fixedly connected to both the left and right sides. Disassembly and assembly mechanisms 9 are slidably connected to the top left and right sides of the ecological module 2. Each disassembly and assembly mechanism 9 includes a sliding rod 901. The surface of the sliding rod 901 is smoothed to reduce friction with the slide groove, ensuring smooth sliding. The sliding rod 901 is slidably connected to the outer left and right sides of the ecological module 2. A connecting frame 902 is fixedly connected to the bottom outer end of the sliding rod 901. The connecting frame 902 provides a stable connection point for the rotating plate 903, allowing it to rotate around that point. The external rotatable connection of 902 is a rotating plate 903. The rotation of the rotating plate 903 can drive the movement of the connecting frame 904 and the sliding rod 905. The other end of the rotating plate 903 is rotatably connected to the connecting frame 904. The function of the connecting frame 904 is to convert the rotational motion of the rotating plate 903 into the linear motion of the sliding rod 905. The bottom of the connecting frame 904 is fixedly connected to the sliding rod 905. The function of the sliding rod 905 is to engage or disengage with the adjacent ecological module 2 or other structures when assembling or disassembling the ecological module 2, so as to realize the quick assembly and disassembly of the ecological module 2.

[0043] Specifically, based on the natural or artificially modified slope soil layer 1, the slope is determined according to engineering requirements and terrain. Multiple ecological modules 2 are fixed at the top of the slope soil layer 1. The modules are equipped with planting holes for planting greenery, and anti-erosion nets 3 are fixed inside to prevent soil loss and support plant roots. Anchor rods 6 are installed on both sides of the slope soil layer 1, which are inserted into the soil layer and reinforced by grouting. Nuts 7 are tightened at the outer ends to generate preload and improve soil stability. The ecological modules 2 are connected to fixing mechanisms 8 on both sides and a disassembly and assembly mechanism 9 is set at the top. The sliding rod 901 of the disassembly and assembly mechanism 9 slides on both sides of the module and is connected to a rotating plate 903 through a connecting frame 902. The rotating plate 903 drives the connecting frame 904 and the sliding clamp rod 905 for quick engagement and disengagement of the ecological modules 2, which facilitates construction and installation.

[0044] Reference Figures 2 to 3 The fixing mechanism 8 includes a connector 801, which is externally fixedly connected to the left and right sides of the ecological module 2. A mounting bracket 802 is externally fixedly connected to the connector 801. The internal space of the mounting bracket 802 is precisely machined, with surface flatness and perpendicularity errors controlled within a very small range, providing precise positioning and stable support for the installation of the rotating shaft 803. The rotating shaft 803 is internally fixedly connected to the mounting bracket 802. The surface roughness of the rotating shaft 803 is extremely low to reduce friction with the rotating clamping plate 804, ensuring that the rotating clamping plate 804 can rotate flexibly around the rotating shaft 803. The rotating shaft 803 is externally rotatably connected to the rotating clamping plate 804. The surface of the rotating clamping plate 804 is treated to improve its hardness and wear resistance. A reset assembly, including a telescopic rod, is externally fixedly connected to the rotating clamping plate 804. Telescopic rod 805 can perform smooth telescopic movement under the action of return spring 806, and at the same time, it guides and protects return spring 806. The telescopic rod 805 is externally fixedly connected to the outside of rotating plate 804. Return spring 806 is sleeved on the outside of telescopic rod 805. When rotating plate 804 rotates around rotating shaft 803, return spring 806 is compressed or stretched, storing elastic potential energy. When the external force disappears, return spring 806 releases elastic potential energy, pushing rotating plate 804 back to the initial position. Positioning rod 807 is fixedly connected to the outside of rotating plate 804. The function of positioning rod 807 is to engage with the positioning structure on adjacent ecological module 2 when rotating plate 804 rotates to a specific position, so as to realize the positioning and fixation between adjacent ecological modules 2, and ensure the stability and accuracy of the entire slope protection structure.

[0045] Specifically, the fixing mechanism 8 is used to stabilize the ecological module 2. The connector 801 connects the left and right sides of the ecological module 2. The external fixed mounting bracket 802 is precisely machined and has a smooth rotating shaft 803 inside, which provides flexible rotation conditions for the rotating plate 804. The surface treatment of the rotating plate 804 improves its hardness and wear resistance. It is externally connected to the reset component. The internal telescopic rod 805 is fitted with a reset spring 806. When the rotating plate 804 rotates, the spring stores elastic potential energy and releases it after the external force disappears, pushing it to reset. The rotating plate 804 is also connected to the positioning rod 807. When it rotates to a specific position, it engages with the positioning structure of the adjacent ecological module 2, thereby realizing the positioning and fixing of the adjacent module, ensuring the stability and accuracy of the slope protection structure, and ensuring the normal operation of the entire ecological slope protection system.

[0046] Reference Figures 3 to 5 The ecological module 2 is internally fixedly connected to a telescopic rod 906. The total length of the telescopic rod 906 is determined according to the internal space and actual functional requirements of the ecological module 2. Its surface is finely polished and treated to reduce friction during extension and retraction. A tension spring 907 is sleeved on the outside of the telescopic rod 906. One end of the tension spring 907 is firmly fixed to the outside of the sliding rod 905 by welding or a special hook, and the other end is fixed to a preset fixing point inside the ecological module 2. This fixing point is reinforced to withstand the tension of the spring. The anti-erosion net 3 has slots on both the left and right sides of its exterior. The exterior of the sliding rod 905 is locked into the slots on the exterior of the anti-erosion net 3. The external rotating plate 804 is rotatably connected to the outside of the mounting frame 802, and the external rotating plate 807 is rotatably connected to the outside of the mounting frame 802. Multiple pipes 4 are fixedly connected to the front of the ecological module 2 to realize functions such as irrigation, drainage or nutrient transport to the soil layer 5, so as to meet the needs of plant growth in the ecological module 2. The soil layer 5 is set inside the ecological module 2. The soil layer 5 provides the nutrients, water and root attachment space required for plant growth. It is an important foundation for the ecological slope protection to realize its ecological function. One end of the tension spring 907 is fixedly connected to the outside of the sliding plate 905, and the other end of the tension spring 907 is fixedly connected to the inside of the ecological module 2.

[0047] Specifically, a finely polished telescopic rod 906 is installed internally according to space and functional requirements, covered with a tension spring 907. One end of the spring is connected to the outside of the sliding clamp 905, and the other end is fixed to a preset reinforcement point inside the ecological module 2. The slots on both sides of the anti-erosion net 3 are locked with the sliding clamp 905. The rotating plate 804 and the positioning clamp 807 rotate outside the mounting frame 802. Multiple pipes 4 are fixed to the front of the ecological module 2 for irrigation, drainage and nutrient transport of the soil layer 5. The soil layer 5 is located inside the module, providing nutrients, water and root attachment space for plant growth. The whole module works together to meet the needs of plant growth and realize the ecological function of ecological slope protection. The tension spring 907 helps the sliding clamp 905 to operate flexibly and ensures that all components fit tightly.

[0048] Working principle: When fixing the ecological module 2, the rotating plate 804 can be pressed and squeezed by the rotating plate 804, which in turn causes the return spring 806 to deform. By placing the ecological module 2 outside the anchor rod 6, the rotating plate 804 can be released, causing the return spring 806 to rebound, which in turn causes the rotating plate 804 to drive the positioning rod 807 to lock tightly with the outside of the anchor rod 6, thereby fixing the ecological module 2.

[0049] When disassembling the anti-erosion net 3, by pulling the sliding rod 901, the sliding rod 901 causes the connecting frame 904 to rotate via the rotating plate 903 through the connecting frame 902. This allows the connecting frame 904 to drive the sliding clamp 905 to slide inside the ecological module 2, thereby pressing the telescopic rod 906. This causes the tension spring 907 outside the telescopic rod 906 to deform, allowing the sliding clamp 905 to contact the anti-erosion net 3. The outer phase of the scouring net 3 is separated. When installing the anti-scouring net 3, by loosening the sliding rod 901, the sliding rod 901 causes the connecting frame 904 to rotate through the connecting bracket 902 and the rotating plate 903. This allows the connecting bracket 904 to drive the sliding clamp 905 to slide inside the ecological module 2, causing the tension spring 907 to rebound. This allows the sliding clamp 905 to lock onto the anti-scouring net 3, thus enabling the installation and removal of the anti-scouring net 3.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
