Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and more specifically, to a flood control device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can water flow be controlled, floods prevented, and water volume regulated and distributed to meet the water needs of people's lives and production. Water conservancy projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, to achieve their objectives.

[0003] Existing support structures are mostly fixed in angle and length, making them difficult to adapt to complex terrain. When faced with floods of varying intensities, their stability is insufficient, easily leading to tilting and deformation of the device. Water-blocking components have poor sealing performance, connections are prone to loosening, flood leakage is a significant problem, and concentrated stress makes them susceptible to damage and inconvenient to maintain. Components in direct contact with floodwater lack effective buffering design, resulting in concentrated water flow impact, rapid device wear, short service life, and inability to reliably cope with various flood conditions.

[0004] This invention can enhance the device's impact resistance, sealing, and adaptability, ensuring reliable flood control. Utility Model Content

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a flood control device for water conservancy projects.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flood control device for water conservancy projects, comprising: a base plate; A vertical plate, nested at the upper end of the base plate; An extension plate is mounted on the upper end of the vertical plate; A baffle, which is movably installed on one side of the vertical plate; A support rod is provided on the other side of the vertical plate. An anchor rod is provided at the bottom of the base plate, and sealing strips are nested on both sides of the vertical plate. The bottom of the base plate is in contact with the ground, and the two sides of the sealing strip are attached to the two sides of the base. The anchor rod penetrates the base plate and extends below the ground.

[0007] A further preferred embodiment: both the upper end of the vertical plate and the upper end of the extension plate are provided with sliding grooves, and the bottom of the extension plate is fixedly installed with sliders. The sliders can be embedded in the sliding grooves, and the sliders and the sliding grooves are detachably connected.

[0008] A further preferred embodiment: a groove is provided on one side of the vertical plate, the bottom plate is arc-shaped on one side and fits against the inner side of the baffle on one side, and a second groove is provided on one side of the bottom plate.

[0009] A further preferred embodiment: several buffer plates are fixedly installed on the outer side of the baffle by bolts, and the outer side of the buffer plates is arc-shaped.

[0010] A further preferred embodiment: a first locking block and a second locking block are fixedly installed on the inner side of the baffle, the first locking block can be embedded in the first groove, and the second locking block can be embedded in the second groove, and the baffle and the vertical plate are detachably connected.

[0011] A further preferred embodiment: an auxiliary rod is fixedly installed on the inner side of the baffle, one end of the auxiliary rod is located at the junction of the vertical plate and the bottom plate, and the other end of the auxiliary rod is located between the first locking block and the second locking block.

[0012] A further preferred embodiment: both ends of the support rod are connected to a base via a rotating rod, the base is fixed by bolts, and an adjusting rod is threadedly connected inside the support rod, with the adjusting rod and the support rod being threadedly connected.

[0013] A further preferred embodiment: a positioning block is fixedly installed on one side of the adjusting rod, the positioning block is embedded inside the support rod, and the positioning block and the inside of the support rod are slidably connected. Beneficial effects

[0014] 1. By incorporating a support rod as a key supporting component of the device, the dual design of flexible adjustment and stable support enhances the overall structure's impact resistance and environmental adaptability. The rotating rods at both ends connect to the base, allowing for free adjustment of the support angle. Combined with the bolt fixing of the base, it can adapt to complex terrains such as slopes and uneven ground, ensuring that the support force is accurately transmitted to the ground. The internal adjustment rod is connected to the support rod via threads, allowing for dynamic adjustment of the length according to the magnitude of the flood impact force, thus controlling the support force. When the flood is rapid, the length is extended to enhance the clamping force, and when the water level drops, the length is shortened to avoid structural overload. The positioning block is embedded inside the support rod and slidably connected, effectively preventing the adjustment rod from shifting or jamming during rotation, ensuring a stable and reliable adjustment process. This allows the support rod to withstand the lateral thrust of sudden strong floods and adapt to the flood control needs of different water levels, significantly reducing the risk of vertical plate tilting and deformation. It provides dynamically adaptable stable support for the entire device, extending its application scenarios from conventional dams to complex areas with rapid water flow. 2. By setting up a baffle, the inner two locking blocks are respectively embedded in the groove one of the vertical plate and the groove two of the bottom plate. Through mechanical interlocking, the sealing strip is forcibly compressed. Compared with the traditional adhesive sealing, the gap is smaller and the connection is tighter, effectively blocking the flood seepage path and solving the seepage problem caused by loose connection. One end of the auxiliary rod rests on the junction of the vertical plate and the bottom plate, and the other end is located between the two locking blocks, forming a triangular support structure. This disperses the flood impact force to the main frame, preventing the locking blocks from deforming and breaking due to local overload, and significantly extending the service life of the baffle. At the same time, the detachable design of the locking blocks and grooves makes the installation and replacement of the baffle more convenient and facilitates later maintenance. The baffle can not only effectively block flood overflow, but also maintain structural stability in long-term use, adapting to different water levels and flood intensities, and building a reliable horizontal water barrier for the protected area. 3. By incorporating a buffer plate, a component directly in contact with floodwaters, the unique structural design significantly reduces the impact force of the water flow, providing effective protection and buffering for the baffle and the overall device. Its outer side is arc-shaped; when floodwaters impact, the arc surface disperses the concentrated water flow force to both sides along the arc, preventing the impact force from acting directly on a single point of the baffle. This significantly reduces the risk of deformation and damage to the baffle due to excessive localized stress. The buffer plate is bolted to the outside of the baffle; this detachable connection method facilitates individual replacement of damaged components without requiring overall repair, reducing maintenance costs. Simultaneously, the arc design guides the water flow smoothly along the surface of the buffer plate, reducing continuous scouring of the baffle and indirectly extending its service life. In response to sudden, strong floods, the buffer plate can quickly absorb some of the impact energy, providing reaction time for the support rods and base plate to stabilize, thereby improving the impact resistance limit of the entire flood control device and making the device more durable and reliable in complex water flow environments. 4. In summary, this type of flood control device for water conservancy projects, through the installation of support rods and other structures, allows for adjustment of the angle and length of the support rods to adapt to complex terrain and stably support the vertical plate; the baffles are reinforced with interlocking blocks to enhance sealing, and the auxiliary rods distribute the force, resulting in efficient water blocking and easy maintenance; the arc-shaped design of the buffer plate disperses the impact of water flow, reduces baffle wear, and facilitates replacement. The combination of these three elements enhances the device's impact resistance, sealing, and adaptability, ensuring reliable flood control. Attached Figure Description

[0021] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0022] Please see Figure 1-5 In this embodiment of the utility model, a flood control device for a water conservancy project includes: a base plate 1; a vertical plate 2 nested on the upper end of the base plate 1; an extension plate 3 installed on the upper end of the vertical plate 2; a baffle 4 movably installed on one side of the vertical plate 2; and a support rod 5 installed on the other side of the vertical plate 2. An anchor rod 6 is provided at the bottom of the base plate 1, and sealing strips 7 are nested on both sides of the vertical plate 2. The bottom of the base plate 1 is in contact with the ground, and the two sides of the sealing strips 7 are attached to the two sides of the base 501. The anchor rod 6 penetrates the base plate 1 and extends below the ground. Both the upper end of plate 2 and the upper end of extension plate 3 are provided with sliding grooves 201. The bottom of extension plate 3 is fixedly installed with sliders 301. The sliders 301 can be embedded in the sliding grooves 201, and the sliders 301 and the sliding grooves 201 are detachably connected. One side of vertical plate 2 is provided with a groove 202. One side of bottom plate 1 is arc-shaped and fits against the inner side of baffle 4. One side of bottom plate 1 is provided with a groove 101. Several buffer plates 401 are fixedly installed on the outer side of baffle 4 by bolts. The outer side of buffer plates 401 is arc-shaped.

[0023] The base plate 1 is anchored by anchor rods 6 at its bottom, extending below ground level. The anchoring force between the anchor rods 6 and the soil firmly fixes the entire device in the flood control area, preventing the device from shifting or overturning due to flood impact. This provides a stable foundation for subsequent water-retaining structures. The vertical plate 2 is nested on top of the base plate 1, with sealing strips 7 on both sides fitting snugly against the sides of the base plate 1. This tight contact forms a sealed structure, preventing water from seeping through the gap between the vertical plate 2 and the base plate 1, reducing the risk of water leakage. The extension plate 3 is embedded in the groove 201 at the top of the vertical plate 2 via a slider 301 at the bottom. It can be flexibly installed according to the actual water level: if the water level is low, the vertical plate 2 alone is sufficient to meet the water-retaining requirements; if the water level rises, the extension plate 3 is added through the groove 201 to directly increase the water-retaining height, adapting to different flood scales. The baffle 4 is movably installed on one side of the vertical plate 2, with its inner side fitting against the arc-shaped side of the base plate 1. The sealing is enhanced by the groove 202 of the vertical plate 2 and the groove 101 of the base plate 1, forming a transverse water barrier to directly block flood overflow. The arc-shaped buffer plate 401 on the outer side of the baffle 4 is fixed with bolts, utilizing its arc-shaped surface to disperse the impact force of the flood, reducing the direct impact load on the baffle 4 and protecting its structure. The support rod 5 on the other side of the vertical plate 2 obliquely supports the vertical plate 2, offsetting the lateral thrust of the flood on the vertical plate 2 and the baffle 4, preventing the vertical plate 2 from tilting or deforming due to excessive force. It is fixed to the anchor rod 6 of the base plate 1, forming a coordinated front-to-back stable system, ensuring the overall structure remains stable under flood impact, exhibiting strong stability and excellent impact resistance. The anchor rod 6 penetrates deep into the ground to fix the base plate 1, and combined with the lateral support of the support rod 5 for the vertical plate 2, forms a double-stabilized structure of bottom anchor and side bracing, capable of resisting the impact force of large floods and preventing device displacement or overturning. The arc-shaped buffer plate 401... 1. By dispersing the force of water flow, the direct impact of flood on the baffle 4 is greatly reduced, the risk of deformation or damage to the baffle 4 is reduced, and the service life of the device is extended. The extension plate 3 and the vertical plate 2 are detachably connected to the slider 301 through the groove 201. The total height of the water barrier can be flexibly adjusted according to the real-time water level, adapting to the flood control needs of different seasons or flood scales. The sealing strips 7 on both sides of the vertical plate 2 are tightly fitted to the bottom plate 1, blocking water from seeping through the gap between the vertical plate 2 and the bottom plate 1. The inner side of the baffle 4 is fitted to the arc surface of the bottom plate 1, and the groove structure enhances the sealing performance, reduces the risk of water seepage, and prevents flood from entering the protected area through the gap. The components are connected by nesting, bolts or groove 201, which is highly detachable, convenient for transportation, installation and later maintenance and replacement, and reduces construction and maintenance costs. The vertical plate 2 and the extension plate 3 form a longitudinal water barrier, and the baffle 4 forms a lateral water barrier supplement. The two work together to build a closed water barrier area, which can effectively block flood overflow and protect riverbanks, farmland, towns and other areas from flood.

[0024] In this embodiment of the present invention, a first locking block 402 and a second locking block 403 are fixedly installed on the inner side of the baffle 4. The first locking block 402 can be embedded in the first groove 202, and the second locking block 403 can be embedded in the second groove 101. The baffle 4 and the vertical plate 2 are detachably connected. An auxiliary rod 404 is fixedly installed on the inner side of the baffle 4. One end of the auxiliary rod 404 is located at the junction of the vertical plate 2 and the bottom plate 1, and the other end of the auxiliary rod 404 is located between the first locking block 402 and the second locking block 403. Both ends of the support rod 5 are connected to the base 501 through rotating rods. The base 501 is fixed by bolts. An adjusting rod 502 is threadedly connected inside the support rod 5. The adjusting rod 502 and the support rod 5 are threadedly connected. A positioning block 503 is fixedly installed on one side of the adjusting rod 502. The positioning block 503 is embedded inside the support rod 5, and the positioning block 503 and the support rod 5 are slidably connected.

[0025] The first locking block 402 on the inner side of the baffle 4 is embedded in the groove 202 of the vertical plate 2, and the second locking block 403 is embedded in the groove 101 of the bottom plate 1. Through the mechanical interlocking of the locking blocks and grooves, not only is the connection stability between the baffle 4 and the main structure enhanced, but the tight contact between the locking blocks and grooves further compresses the sealing strip 7, strengthening the sealing at the gaps and reducing the leakage of floodwater from the connection between the baffle 4 and the vertical and bottom plates 1. One end of the auxiliary rod 404 on the inner side of the baffle 4 rests against the junction of the vertical plate 2 and the bottom plate 1, and the other end is located between the first locking block 402 and the second locking block 403, forming a triangular support structure. When floodwater impacts the baffle 4, the auxiliary rod 404 can transfer part of the impact force to the connection between the vertical plate 2 and the bottom plate 1, dispersing the load on the locking blocks and preventing the locking blocks from deforming or breaking due to excessive local stress, thus protecting the reliability of the connection between the baffle 4 and the main structure. The support rod 5 is connected to the base 501 at both ends via rotating rods. These rotating rods can rotate freely, allowing the support rod 5 to adjust its support angle according to the tilt of the vertical plate 2 or the direction of the flood impact. An adjusting rod 502 inside the support rod 5 is threadedly connected to it. Rotating the adjusting rod 502 changes the total length of the support rod 5, thereby precisely adjusting the support force on the vertical plate 2. When the flood impact increases, the length of the support rod 5 is extended to increase the clamping force on the vertical plate 2; when the impact decreases, the length is shortened to avoid excessive support that could deform the vertical plate 2. A positioning block 503 on one side of the adjusting rod 502 is embedded inside the support rod 5 and slidably connected. Its function is to limit the rotation trajectory of the adjusting rod 502, preventing it from shifting or jamming during length adjustment, ensuring the stability and accuracy of the length adjustment, and guaranteeing that the support rod 5 always applies a balanced support force to the vertical plate 2. The base 501 is bolted to the ground, forming an adjustable and firmly fixed support end point in conjunction with the rotating rod. This ensures that the supporting force of the support rod 5 is effectively transmitted to the ground, rather than failing due to slippage of the base 501. This further enhances the practicality, stability, and adaptability of the device. The interlocking design of the locking blocks 402 and 403 with the grooves 202 and 101, compared to simple sealing, uses mechanical interlocking to forcibly compress the sealing strip 7, making the gaps between the baffle 4 and the vertical plate 2 and the base plate 1 smaller. This effectively blocks the seepage path of floodwater and solves the problem of water leakage caused by loose connections in traditional flood control devices. The triangular support formed by the auxiliary rod 404 disperses the force on the baffle 4, preventing damage to the locking blocks due to local overload and extending the service life of the baffle 4. The dual adjustment function of the angle and length of the support rod 5 allows for dynamic adjustment of the support force according to the magnitude and direction of the flood impact, ensuring that the vertical plate 2 remains stable under different impact loads and preventing structural deformation or overturning due to insufficient support. The detachable connection between the locking block and the groove makes the installation, disassembly and replacement of the baffle 4 more convenient and easier for later maintenance; the design of the rotating rod and adjusting rod 502 of the support rod 5 allows the device to adapt to the flood control needs of different terrains and different water levels, without the need to replace the entire device due to environmental changes, thus reducing application costs.The bolt fixing of the base 501 and the guiding function of the positioning block 503 ensure that the support rod 5 will not loosen or shift under long-term stress or flood impact. This makes the device suitable not only for conventional riverbank and embankment flood control, but also for complex scenarios such as sudden strong floods and rapid water flow, thus improving the reliability of flood control. In summary, by optimizing the connection, strengthening the support, and improving adjustability, the flood control device has significantly improved in terms of sealing, impact resistance, adaptability, and stability, and can better meet the flood control needs in complex water conservancy environments.
