Description

Technical Field

[0001] This utility model relates to the field of dike reinforcement construction technology, and in particular to a device for riverbank protection and reinforcement. Background Technology

[0002] Dike reinforcement construction refers to a series of engineering construction measures carried out on existing dikes in order to improve their stability, seepage resistance and flood control capacity. Riverbank protection and reinforcement devices aim to improve the stability and erosion resistance of riverbanks, and protect the ecological environment and the safety of people's lives and property around the riverbanks.

[0003] A search revealed Chinese patent publication number CN220301244U, which discloses a river embankment reinforcement device. The device includes an embankment body, which slopes downwards and comprises an embankment head, a lower slope, a buffer slope, and a breakwater. The buffer slope is located at the connection between the lower slope and the breakwater. The surface of the embankment body is layered with a soil layer and a sand cushion layer from top to bottom. Reinforcing mesh is installed on the surfaces of the lower slope and the buffer slope. A portal-shaped semi-circular arched retaining wall is installed on the surface of the breakwater. A waterproof box is installed on the embankment head, containing a pressure pump and a power supply. The pressure pump is connected to a water source via a drainage pipe. This invention effectively prevents water waves from overflowing the embankment during the flood season, protecting the protective layer on the embankment surface. It effectively disperses impact forces, is less prone to damage, extends the service life of the embankment, and avoids frequent maintenance.

[0004] The aforementioned patent specification mentions that "the self-energy-dissipating breakwater greatly reduces the impact force of water flow, effectively preventing waves from crossing the embankment under the impact force during the flood season. The portal-shaped semi-circular arched embankment can reduce the scouring force of water waves during the backflow after impact, protecting the protective layer on the embankment surface. The portal-shaped semi-circular arch structure can effectively disperse the impact force, is not easily damaged, and has a long service life." Although the aforementioned patent can effectively disperse the impact force of water waves, the reinforcement plates in some embankments in the prior art are easily damaged after long-term use. Disassembling the reinforcement plates is difficult, which will prolong the maintenance time, increase the maintenance cost, and even cause further damage to the embankment during the maintenance process, thus affecting the effectiveness and sustainability of embankment protection. Therefore, in view of the above shortcomings, a river embankment protection and reinforcement device is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a riverbank protection and reinforcement device, which aims to improve the problem that the reinforcement plates in some fixed devices in existing technologies are difficult to disassemble and replace.

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

[0007] A riverbank protection and reinforcement device includes a base, with bank bodies fixedly connected to the top left and right sides of the base. A sealed box is fixedly connected inside the bank body, and a motor is fixedly connected to the bottom inner wall of the sealed box. A rotating rod is fixedly connected to the drive end of the motor, and a circular plate is fixedly connected to the outside of the rotating rod. Two fixed rods are fixedly connected to one side of the circular plate, and a sleeve is fitted around the fixed rod. A connecting rod is rotatably connected to the outside of the sleeve. An inner cavity is formed inside the two bank bodies, and sliding plates are slidably connected to the left and right sides of the inner walls of the inner cavities. A fixed block is fixedly connected to one side of the sliding plate, and two locking blocks are fixedly connected to the far sides of the two fixed blocks. A reinforcement plate is detachably connected to one side of the bank body, and square openings are formed on the front and rear sides of the reinforcement plate. A buffer component for reducing water flow velocity is fixedly connected to one side of the reinforcement plate.

[0008] Furthermore, the reinforcement plate can be disassembled and replaced simply by starting the motor, eliminating the need for complex manual operations. This significantly improves maintenance efficiency and reduces maintenance costs. The various components of the device are tightly connected, ensuring stable operation and minimizing the likelihood of malfunctions during operation, thus enhancing the device's reliability and safety.

[0009] As a further description of the above technical solution:

[0010] The buffer assembly includes two fixed columns, one side of which is fixedly connected to one side of the reinforcing plate. A fixed box is fixedly connected to one side of each of the two fixed columns. Two support rods are fixedly connected to the front inner wall of each fixed box. A buffer plate is slidably connected to the outside of each support rod. A sliding block is slidably connected to the outside of each support rod. A telescopic spring is sleeved on the outside of each support rod. A limit block is fixedly connected to the rear side of each support rod.

[0011] Furthermore, the fixing column, as a key component connecting the reinforcing plate and the fixing box, provides solid support for the entire buffer assembly. On the one hand, the fixing column ensures the strong connection between the buffer assembly and the reinforcing plate, preventing easy separation due to external forces under the impact of water flow. On the other hand, the fixing column transfers the weight of the buffer assembly and the impact force of the water flow to the reinforcing plate and the embankment body, dispersing the stress and improving the stability of the entire device.

[0012] As a further description of the above technical solution:

[0013] The buffer plate is externally slidably connected to the inner wall of the fixed box, and the two sliding blocks are externally slidably connected to the upper and lower sides of the inner wall of the fixed box.

[0014] Furthermore, the buffer plate is externally slidably connected to the inner wall of the fixed box, allowing it to move smoothly along a fixed direction when impacted by water flow. The inner wall of the fixed box provides a defined track for the buffer plate, limiting its range of motion and preventing it from shifting or wobbling under water flow impact. This ensures that the buffer plate accurately transmits the water flow impact force to the sliding block and the telescopic spring, thereby achieving an effective buffering effect.

[0015] As a further description of the above technical solution:

[0016] One side of the telescopic spring is fixedly connected to the front side of the sliding block, and the other side of the telescopic spring is fixedly connected to the inner wall of the front side of the fixed box;

[0017] Furthermore, when the water flow impacts the buffer plate, the buffer plate moves the sliding block. At this time, one side of the telescopic spring is stretched or compressed as the sliding block moves forward. Since the other side of the telescopic spring is fixedly connected to the front inner wall of the fixed box, the spring can store energy during this process, converting the impact force of the water flow into the elastic potential energy of the spring. When the impact force of the water flow weakens, the telescopic spring releases its elastic potential energy, pushing the sliding block and the buffer plate back to their initial positions, thereby achieving the buffering and reduction of the impact force of the water flow.

[0018] As a further description of the above technical solution:

[0019] A telescopic plate is fixedly connected to the front side of the buffer plate, and the front side of the telescopic plate is fixedly connected to the front inner wall of the fixed box.

[0020] Furthermore, when water impacts the buffer plate, the buffer plate moves backward, causing the telescopic plate to move along with it. The telescopic plate has a certain degree of elasticity and extensibility, allowing it to deform further when the buffer plate is impacted by water flow, absorbing more energy. This effectively increases the buffer assembly's ability to withstand the impact of water flow, better protecting the embankment itself.

[0021] As a further description of the above technical solution:

[0022] The outer side of the rotating rod is rotatably connected to the inner wall of the embankment body, and the far sides of the two connecting rods are rotatably connected to the near sides of the two sliding plates.

[0023] Furthermore, the external rotatable connection of the rotating rod is to the inner wall of the embankment body, providing stable support and a rotation track for the rotating rod. The embankment body, as a relatively robust structure, effectively limits the displacement of the rotating rod, preventing it from swaying or shifting during rotation. This ensures that the motor's power is smoothly transmitted to the circular plate and other related components, guaranteeing the normal operation of the entire device.

[0024] As a further description of the above technical solution:

[0025] The outer side of the card block engages with the inner wall of the square opening, and the upper and lower sides of the inner cavity are fixedly connected with limit rods. The inner sides of the two sliding plates are slidably connected to the front and rear sides of the limit rods.

[0026] Furthermore, the snap-fit ​​connection can also prevent the reinforcement plate from loosening or shifting during use. Because the snap-fit ​​block fits tightly with the inner wall of the square opening, the reinforcement plate will not easily detach from the embankment body when subjected to water flow impact, thus ensuring the stability and reliability of the embankment protection and reinforcement device.

[0027] As a further description of the above technical solution:

[0028] A limiting plate is fixedly connected to one side of the fixed rod, and the outside of the rotating rod is rotatably connected to the inside right side of the sealed box.

[0029] Furthermore, the fixed rod improves the overall stability of the device, and the sealed box prevents the rotating rod from shaking during movement.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, by starting the motor, the motor drives the rotating rod to rotate, the rotating rod drives the circular plate to rotate, the circular plate drives the fixed rod to move, the fixed rod drives the sleeve to move, the sleeve drives the connecting rod to rotate, the connecting rod drives the sliding plate to slide, the sliding plate drives the fixed block to move, and the fixed block drives the locking block to move, thereby realizing the disassembly and replacement of the reinforcing plate in the reinforcing device, thereby reducing maintenance time and cost and improving the use effect of the reinforcing plate.

[0032] 2. In this utility model, the water flow drives the buffer plate to slide, the buffer plate drives the sliding block to move, and the sliding block drives the telescopic spring to compress, thereby achieving buffering of the water flow. This can effectively disperse and reduce the impact force of the water flow, reduce the direct impact of the water flow on the embankment, and protect the integrity of the embankment structure.

[0039] 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.

[0040] Reference Figures 1 to 3This utility model provides an embodiment of a riverbank protection and reinforcement device, comprising a base 1, which is the foundation of the device and provides stable support for the entire protection and reinforcement device. A riverbank body 2 is fixedly connected to the top left and right sides of the base 1. A sealed box 3 is fixedly connected inside the riverbank body 2. A motor 4 is fixedly connected to the bottom inner wall of the sealed box 3. After the motor 4 starts, it drives a rotating rod 5 to rotate, serving as the power source for the entire device. The driving end of the motor 4 is fixedly connected to the rotating rod 5, which connects the motor 4 and a circular plate 6, transmitting the power of the motor 4 to the circular plate 6. A circular plate 6 is fixedly connected to the outside of the rotating rod 5, rotating with the rotation of the rotating rod 5, thus driving a fixed rod 7 to move. Two fixed rods 7 are fixedly connected to one side of the circular plate 6, and the fixed rods 7 are connected to a connecting rod 9 via sleeves 8, transmitting the movement of the circular plate 6 to the connecting rod 9. A limit plate 17 is fixedly connected to one side to prevent the sleeves 8 from slipping off the fixed rods 7. Sleeves 8 are fitted onto the outside of the fixed rods 7. A connecting rod 9 is rotatably connected to the outside of the sleeve 8. This connecting rod rotates with the movement of the fixed rod 7, causing the connecting rod 9 to move. The connecting rod 9 connects the sleeve 8 and the sliding plate 11, transmitting the movement of the sleeve 8 to the sliding plate 11. The two embankment bodies 2 have internal cavities 10. Sliding plates 11 are slidably connected to the left and right sides of the inner wall of each cavity 10. The sliding plates 11 slide within the internal cavities 10 of the embankment body 2 as the connecting rod 9 moves. One side of the sliding plate 11... A fixing block 12 is fixedly connected to the side, and the fixing block 12 is connected to the reinforcing plate 14 through the locking block 13 to fix the reinforcing plate 14. Two locking blocks 13 are fixedly connected to the opposite side of the two fixing blocks 12. The reinforcing plate 14 is detachably connected to one side of the embankment body 2. The reinforcing plate 14 is used to cooperate with the locking block 13 to achieve the connection with the embankment body 2. Square openings 15 are opened on both the front and rear sides of the interior of the reinforcing plate 14. A buffer component for reducing the flow velocity of water is fixedly connected to one side of the reinforcing plate 14.

[0041] Specifically, the reinforcing plate 14 is detachably connected to one side of the embankment body 2. When the reinforcing plate 14 is damaged, it can be quickly disassembled and replaced, reducing maintenance time and cost. It eliminates the need for large-scale maintenance of the entire embankment, improving maintenance efficiency. Different types or specifications of reinforcing plates 14 can be replaced according to different usage needs and damage conditions to meet various practical application scenarios and improve the performance of the reinforcing plate 14. The base 1 provides stable support for the entire device, and all components are tightly connected. The rotating rod 5 rotates stably in the sealed box 3, and the sliding plate 11 slides smoothly in the inner cavity 10 with the help of the limiting rod 16. The limiting plate 17 on the fixed rod 7 prevents the sleeve 8 from slipping off. These designs ensure the stability of the device during operation.

[0042] Reference Figure 1 , Figure 4The buffer assembly includes two fixed posts 25, one side of which is fixedly connected to one side of the reinforcing plate 14 to provide support for the fixed box 18. Two support rods 21 are fixedly connected to the inner front wall of the fixed box 18, providing sliding tracks for the buffer plate 20 and the sliding block 22. The buffer plate 20 and the sliding block 22 are slidably connected to the outside of the support rods 21, and a telescopic spring 23 is sleeved on the outside. A limit block 24 is fixedly connected to the rear side to prevent the sliding block 22 from slipping off the support rod 21. The buffer plate 20 is slidably connected to the inner wall of the fixed box 18, and a limit block 24 is fixedly connected to the front side. When water flows, the telescopic plate 19 moves the sliding block 22, compressing the telescopic spring 23 to buffer the water flow. The sliding block 22 is externally slidably connected to the upper and lower sides of the inner wall of the fixed box 18, and moves with the buffer plate 20 to compress the telescopic spring 23. One side of the telescopic spring 23 is fixedly connected to the front side of the sliding block 22, and the other side is fixedly connected to the front inner wall of the fixed box 18. It absorbs the impact force of the water flow through compression and extension. The front side of the telescopic plate 19 is fixedly connected to the front inner wall of the fixed box 18, and works with the buffer plate 20 to increase the buffering effect.

[0043] Specifically, multiple fixed columns 25 are fixedly connected to one side of the reinforcing plate 14, providing reliable support for the fixed box 18 and ensuring the stability of the buffer assembly during operation, thereby effectively buffering the water flow. The support rod 21 on the inner wall of the front side of the fixed box 18 provides a sliding track for the buffer plate 20 and the sliding block 22, allowing them to move smoothly in a predetermined direction under the impact of water flow, ensuring the orderly progress of the buffering process. The sliding block 22 is externally slidably connected to the upper and lower sides of the inner wall of the fixed box 18, thereby further restricting the range of motion of the sliding block 22, making it move only in a specific direction, improving the working stability of the buffer assembly. The rear limiting block 24 can effectively prevent the sliding block 22 from slipping off the support rod 21, ensuring that the components of the buffer assembly will not separate under the impact of water flow, thus guaranteeing the reliability and durability of the device. When the water flow impacts the buffer plate 20, the buffer plate 20 drives the sliding block 22 to move, compressing the telescopic spring 23. The telescopic spring 23 absorbs the impact force of the water flow through compression and extension, thereby achieving buffering of the water flow and reducing the direct impact of the water flow on the embankment. The telescopic plate 19 on the front side of the buffer plate 20 cooperates with the buffer plate 20 to increase the buffering effect. Under the impact of water flow, the telescopic plate 19 can further absorb and disperse the energy of the water flow, improving the buffering capacity of the buffer assembly.

[0044] Reference Figures 2 to 4The buffer plate 20 is externally slidably connected to the inner wall of the fixed box 18. The two sliding blocks 22 are externally slidably connected to the upper and lower sides of the inner wall of the fixed box 18. One side of the telescopic spring 23 is fixedly connected to the front side of the sliding block 22, and the other side of the telescopic spring 23 is fixedly connected to the front inner wall of the fixed box 18. The front side of the buffer plate 20 is fixedly connected to the telescopic plate 19, and the front side of the telescopic plate 19 is fixedly connected to the front inner wall of the fixed box 18. The front side of the buffer plate 20 is fixedly connected to the telescopic plate 19, and the front side of the telescopic plate 19 is fixedly connected to the front inner wall of the fixed box 18. The outer side of the locking block 13 engages with the inner wall of the square opening 15. The upper and lower sides of the inner cavity 10 are fixedly connected to the limiting rods 16. The inner sides of the two sliding plates 11 are internally slidably connected to the front and rear sides of the limiting rods 16. One side of the fixed rod 7 is fixedly connected to the limiting plate 17. The outer side of the rotating rod 5 is rotatably connected to the right side of the inner cavity 3.

[0045] Specifically, the buffer plate 20 slides on the inner wall of the fixed box 18, and the sliding block 22 slides on the upper and lower sides of the inner wall of the fixed box 18. When the water flow impacts the buffer plate 20, the buffer plate 20 drives the sliding block 22 to move, compressing the telescopic spring 23. The telescopic spring 23 connects the sliding block 22 and the front inner wall of the fixed box 18. Through compression and extension, it effectively absorbs the impact force of the water flow. At the same time, the telescopic plate 19 on the front side of the buffer plate 20 further increases the buffering effect, and together they play the role of stabilizing and buffering the water flow, reducing the direct impact of the water flow on the embankment, and protecting the embankment structure. The locking block 13 engages with the inner wall of the square opening 15, so that the reinforcing plate 14 is firmly connected to the embankment body 2. When it is necessary to replace the reinforcing plate 14, the locking block 13 can be disengaged from the square opening 15 through the transmission structure inside the device, realizing convenient disassembly and replacement, reducing maintenance costs and time. The upper and lower limit rods 16 are slidably connected to the inside of the sliding plate 11, providing a stable track for the movement of the sliding plate 11, limiting the direction of movement of the sliding plate 11, preventing it from deviating or shaking during movement, and ensuring that the sliding plate 11 can accurately drive the fixed block 12 and the locking block 13 to move according to the design requirements, so as to realize the fixing and disassembly operation of the reinforcing plate 14. The limit plate 17 on one side of the fixed rod 7 can effectively prevent the sleeve 8 from slipping off the fixed rod 7, ensuring the stability and reliability of the internal transmission structure of the device, ensuring that the power of the motor 4 can be accurately transmitted to each component, and realizing the normal operation of the device. The rotating rod 5 is externally rotatably connected to the right side of the sealed box 3, providing stable support and rotation track for the rotating rod 5, ensuring that there is no shaking or deviation when the motor 4 drives the rotating rod 5 to rotate, and ensuring that the power transmission of the device is stable and reliable.

[0046] Working principle: By starting motor 4, motor 4 drives rotating rod 5 to rotate, which in turn drives circular plate 6 to rotate. Circular plate 6 then drives fixed rod 7 to move, which in turn drives sleeve 8 to move. Sleeve 8 then drives connecting rod 9 to rotate, which in turn drives sliding plate 11 to slide. Sliding plate 11 then drives fixed block 12 to move, which in turn drives locking block 13 to move. This allows for the disassembly and replacement of reinforcing plate 14 in the reinforcement device, thereby reducing maintenance time and costs and improving the effectiveness of reinforcing plate 14.

[0047] As the water flows, it causes the buffer plate 20 to slide, which in turn moves the sliding block 22. The sliding block 22 then compresses the telescopic spring 23, thus buffering the water flow. This effectively disperses and reduces the impact of the water flow, lowering its direct impact on the embankment and protecting the integrity of the embankment structure.

[0048] 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.
