Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering, specifically a water conservancy riverbank protection device. Background Technology

[0002] Riverbank protection is a crucial link in ensuring the ecological and engineering safety of water conservancy projects. Its core function is to reduce the damage to riverbanks caused by water erosion and rainwater runoff through artificial intervention, preventing slope collapse and soil loss, while maintaining the flood control capacity of the river and the ecological stability of the slope. In practical applications, the protection devices need to be adapted to the different topographic slopes, water flow velocities, and soil characteristics of different rivers. They must have sufficient structural strength to resist natural external forces, while also taking into account ease of construction and long-term weather resistance, ensuring that they can continue to play a protective role in complex environments such as water immersion and temperature changes. It is an important foundation for maintaining the balance of the river ecosystem and the long-term operation of water conservancy projects.

[0003] Currently, most existing riverbank protection devices adopt an integrated fixed structure with fixed and non-adjustable protection strength. They cannot flexibly and stably add auxiliary protective materials such as rhomboid stones according to the scour degree of different sections of the riverbank slope to make them work with the device for slope protection, resulting in insufficient protection in some easily scoured areas. Utility Model Content

[0004] The purpose of this invention is to provide a water conservancy riverbank protection device to solve the problem in the existing technology that the auxiliary protective materials such as rhomboid stones cannot be flexibly and stably added according to the needs, resulting in insufficient protection in some easily eroded areas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water conservancy riverbank protection device, comprising a slope protection frame, a slope protection net, and a limiting rod; two slope protection frames are provided, and a slope protection net is fixedly connected to one side of the two slope protection frames that are close to each other; a limiting rod is movably installed on the top of the slope protection frame, and a limiting bolt is movably installed between the limiting rod and the slope protection frame; a fixing block is fixedly connected to one side of the slope protection frame, and a connecting block is fixedly connected to the other side of the slope protection frame.

[0006] Preferably, one of the slope protection frames has a bolt hole inside, and the limiting bolt is threadedly connected to the bolt hole.

[0007] Preferably, a limiting groove is provided inside the slope protection frame at the top of the bolt hole, and the limiting rod is fitted into the limiting groove.

[0008] Preferably, a shaft is installed on one side of the limiting rod, and a groove is provided inside the other slope protection frame, with the shaft fitting into the groove.

[0009] Preferably, at least three sets of the limiting rods are provided, and the top of the limiting bolt is provided with a diamond-shaped protrusion.

[0010] Preferably, the bottom of the slope protection frame is fixedly connected with a rod, and at least four rods are provided.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model uses a double slope protection frame combined with a slope protection net to cover the slope, and multiple rods to achieve stable fixation of the device, which can directly block water erosion and reduce soil loss; at the same time, by utilizing the rotation structure of the limiting rod and shaft, combined with the fixing function of the limiting bolt, bolt hole and limiting groove, the staff can flexibly add auxiliary materials such as diamond-shaped stones, and limit them to work together with the device for protection by limiting the limiting rod, which not only enhances the slope protection effect, but also adapts to different slope protection needs. The weather-resistant material can also ensure the long-term stable operation of the device.

[0013] 2. This utility model uses the interlocking and overlapping design of connecting blocks and fixing blocks to increase the contact area between adjacent devices during splicing. Combined with the fixing rod, it improves the overall stability and prevents loosening at the splicing point. At the same time, the drainage channel formed by the splicing of the two blocks, combined with the water diversion channel on the top of the fixing block and the seepage function of the slope protection net, constructs an efficient drainage system to prevent water accumulation from eroding the slope, achieving the dual functions of protection and drainage, further improving the reliability of the slope protection and reducing maintenance costs.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As attached Figure 1 To be continued Figure 4 As shown:

[0023] Example 1: This utility model provides a water conservancy river slope protection device, including a slope protection frame 1, a slope protection net 2 and a limiting rod 3; two slope protection frames 1 are provided, and the slope protection net 2 is fixedly connected to the side of the two slope protection frames 1 that are close to each other. The limiting rod 3 is movably installed on the top of the slope protection frame 1, and the limiting bolt 301 is movably installed between the limiting rod 3 and the slope protection frame 1.

[0024] In this embodiment, the slope protection frame 1 is made of Q355 weathering steel, containing copper, phosphorus, and chromium weathering elements, which can form a dense oxide rust layer to resist corrosion, with a tensile strength of 510-600MPa; the slope protection mesh 2 is 304 stainless steel woven mesh with 5cm×5cm mesh size, which can retain soil and allow water to seep in; the limiting rod 3 is 6061-T6 aluminum alloy, which is anodized and has high tensile strength; the limiting bolt 301 is 45# steel with heat treatment; the fixing block 6 and the connecting block 4 are made of high-density polyethylene, which is acid and alkali resistant and anti-aging; the insertion rod 5 is 20# seamless steel pipe, hot-dip galvanized, with a zinc layer ≥85μm, and a conical bottom. During operation, the worker will hang the four insertion rods 5 vertically. The protective netting 2 is driven directly into the slope soil, using soil friction and wrapping force to fix the slope protection frame 1. The slope protection netting 2 directly covers the slope for retaining soil and guiding water. When enhanced protection is needed, the limiting bolt 301 is loosened, and the limiting rod 3 is opened with the shaft 302 as the center. Diamond-shaped stones and other materials are laid at the front end of the slope protection netting 2. Then the limiting rod 3 is reset and the limiting bolt 301 is tightened. The limiting bolt 301 is threadedly connected to the bolt hole 102, and the limiting rod 3 is engaged with the limiting groove 103 to achieve the limiting. This allows the added materials and the device to work together to protect the slope. The dual structure of basic protection and adjustable auxiliary protection, the weather-resistant material ensures long-term stability, and the rotatable design of the limiting rod 3 allows for flexible addition of slope protection materials to adapt to different slope needs.

[0025] In one embodiment of the present invention, a bolt hole 102 is provided inside one of the slope protection frames 1, and a limiting bolt 301 is threadedly connected to the bolt hole 102.

[0026] When it is necessary to fix the relative position of the limiting rod 3 and the slope protection frame 1, align the limiting bolt 301 with the bolt hole 102 and rotate it clockwise. Since the limiting bolt 301 and the bolt hole 102 are threadedly connected, with the rotation operation, the limiting bolt 301 will gradually be screwed into the bolt hole 102. Through the interlocking force between the threads, the limiting bolt 301 is stably fixed in the bolt hole 102, thereby firmly locking the limiting rod 3 onto the slope protection frame 1.

[0027] In one embodiment of this utility model, a limiting groove 103 is provided inside the slope protection frame 1 at the top of the bolt hole 102, and the limiting rod 3 is fitted into the limiting groove 103.

[0028] When installing the limiting rod 3, first align the corresponding part of the limiting rod 3 with the limiting groove 103, and then embed the limiting rod 3 into the limiting groove 103. The limiting groove 103 plays a positioning and guiding role for the limiting rod 3, which can quickly determine the installation position of the limiting rod 3 on the slope protection frame 1, avoid positional deviation during installation, and improve installation efficiency. At the same time, the fitting structure of the limiting groove 103 and the limiting rod 3 can restrict the movement of the limiting rod 3 in the horizontal direction. With the threaded connection between the limiting bolt 301 and the bolt hole 102, the limiting rod 3 is double-constrained from both horizontal and vertical directions, further enhancing the stability of the connection between the limiting rod 3 and the slope protection frame 1.

[0029] In one embodiment of the present invention, a shaft 302 is installed on one side of the limiting rod 3, and a groove 101 is provided inside the other slope protection frame 1, and the shaft 302 is fitted into the groove 101.

[0030] When assembling the connection structure between the two slope protection frames 1 and the limiting rod 3, align the shaft 302 on one side of the limiting rod 3 with the groove 101 on the other slope protection frame 1, and insert the shaft 302 into the groove 101. The shaft 302 can rotate around its own axis within the groove 101, allowing the limiting rod 3 to adjust its angle relative to the other slope protection frame 1 with the shaft 302 as the center of rotation.

[0031] In one embodiment of this utility model, at least three sets of limiting rods 3 are provided, and a diamond-shaped protrusion is provided on the top of the limiting bolt 301.

[0032] Three or more sets of limit rods 3 are evenly distributed between two slope protection frames 1, which can distribute the force between the two slope protection frames 1 to multiple sets of limit rods 3, and prevent a single limit rod 3 from being damaged due to excessive force.

[0033] In one embodiment of this utility model, the bottom of the slope protection frame 1 is fixedly connected with a plug rod 5, and at least four plug rods 5 are provided.

[0034] When installing the slope protection device, align the four or more insertion rods 5 at the bottom of the slope protection frame 1 with the designated positions on the riverbank slope, and then insert the insertion rods 5 into the slope soil using external force. After the insertion rods 5 penetrate the soil, they form a tight bond with the soil. Utilizing the friction and enveloping force of the soil on the insertion rods 5, the slope protection frame 1 is fixed to the slope, preventing the slope protection frame 1 from sliding or tipping over under conditions such as water erosion and gravity. The four or more insertion rods 5 are evenly distributed at the bottom of the slope protection frame 1, which allows the force at the bottom of the slope protection frame 1 to be evenly distributed to each insertion rod 5, and then transferred to the surrounding soil through the insertion rods 5. This prevents individual insertion rods 5 from being pulled out or damaged due to concentrated force, further improving the installation stability of the slope protection frame 1 on the slope, providing a solid bottom support for the entire slope protection device, and ensuring that the device can stably and long-term protect the riverbank slope.

[0035] Working Principle: Workers first use the conical inserts 5 at the bottom of the slope protection frame 1 to fix the entire device to the designated area of ​​the riverbank slope. After the inserts 5 penetrate the soil, the soil's enveloping force and friction provide stable bottom support for the device, preventing displacement during water erosion or slight slope deformation. Once in place, the slope protection netting 2 between the two slope protection frames 1 directly covers the slope surface, blocking rainwater or river water from directly eroding the slope soil and reducing topsoil loss. Simultaneously, the mesh structure of the slope protection netting 2 allows for normal water infiltration, preventing softening and landslides caused by water accumulation. When further enhancement of the slope protection effect is needed, workers can... Loosen the limiting bolt 301, and use the shaft 302 on one side of the limiting rod 3 as the fulcrum to pull the limiting rod 3 outward. Then, lay auxiliary slope protection materials such as diamond-shaped stones on the front end of the slope protection net 2. Then, rotate the limiting rod 3 in the opposite direction to reset it and tighten the limiting bolt 301. Through the thread engagement between the limiting bolt 301 and the bolt hole 102 on the slope protection frame 1, and the engagement and limitation between the limiting rod 3 and the limiting groove 103 inside the slope protection frame 1, the limiting rod 3 forms a lateral obstruction to the auxiliary materials, so that the auxiliary materials work together with the slope protection net 2 and the slope protection frame 1 to improve the protection strength of the slope. Moreover, the whole process can be flexibly adjusted according to the actual protection needs of the slope without modifying the main body of the device.

[0036] Example 2: This example is basically the same as the previous example, except that a fixing block 6 is fixedly connected to one side of the slope protection frame 1, and a connecting block 4 is fixedly connected to the other side of the slope protection frame 1.

[0037] The components in this embodiment are made of the same materials as those in Embodiment 1. The only difference is that a 10cm wide and 5cm deep V-shaped water channel is added to the top of the fixing block 6, and the thickness of the connecting block 4 is increased by 2cm. The mating surfaces of the two are stepped. When multiple devices are assembled, the connecting blocks 4 and fixing blocks 6 of adjacent devices are aligned so that the connecting block of the previous device is embedded in the stepped mating surface of the fixing block of the next device. The stepped surface increases the contact area, and the stability of the assembly is improved by fixing with the insert rod 5. At the same time, a 5cm wide and 2cm high longitudinal drainage channel is formed between the connecting block 4 and the fixing block 6. Combined with the U-shaped water channel of the fixing block 6, it can collect and drain the water accumulated on the slope, preventing the water from softening the soil. Combined with the water guiding of the slope protection net 2, a drainage system is formed. The stepped mating solves the problem of the stability of multiple device assembly. The assembly structure and the water channel are used to build a collaborative drainage system, so that the device has both protection and drainage functions, and is suitable for river slopes with frequent rainfall.

[0038] Working Principle: For the protection of long riverbank slopes, when workers assemble multiple devices, they align the connecting block 4 and fixing block 6 of adjacent devices, embedding the connecting block 4 of the preceding device into the fixing block 6 of the following device, forming a superimposed splicing structure. This superimposed design increases the contact area between adjacent devices. Combined with the fixing effect of the insertion rod 5 of each device, it effectively prevents loosening and misalignment at the splicing point due to water flow impact and uneven slope stress, ensuring the overall stability of the assembled devices. Simultaneously, a longitudinal drainage channel naturally forms between the connecting block 4 and fixing block 6 of adjacent devices after splicing. The drainage channel runs in the same direction as the slope, quickly draining surface water. Furthermore, the water diversion channel at the top of the fixing block 6 actively collects rainwater or slope runoff from above and directs it into the drainage channel, further accelerating drainage. The synergistic effect of the drainage channel and water diversion channel, combined with the permeability of the slope protection net 2, forms a complete drainage system.

[0039] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
