Technical Field
[0001] This invention relates to the field of flood control barrier technology, specifically a retractable anti-collision flood control barrier suitable for confined spaces. Background Technology
[0002] In river flood control, structures such as flood dikes and flood dikes combined with wave walls / flood barriers are commonly used to contain floodwaters within the river channel, protecting residents and roads outside the channel while also catering to residents' needs for water viewing. Flood dikes and flood dikes combined with wave walls / flood barriers are typically quite tall, ranging from 6 to 15 meters, requiring significant space outside the river channel. This results in high investment costs and is uneconomical, with difficulties in land acquisition and coordination. This is especially true in densely populated mountainous and low-lying areas where traditional flood control structures are difficult to implement and lack the ability to buffer and absorb impacts, making them prone to deformation and damage. When floodwaters create waves, the height cannot be adjusted in time to withstand the direct impact of the waves. Furthermore, traditional dikes and barriers are inconvenient to retract and store in limited spaces, occupying river channel or embankment space and affecting daily traffic and aesthetics. Therefore, there is an urgent need for a retractable flood barrier structure that can fully utilize existing retaining walls or sturdy bank embankments. This retractable structure must not only meet the requirements of highway traffic safety and collision prevention, and mitigate the impact force of floods, but also allow for flexible adjustment of its height during flood season to effectively block floods and avoid the damage caused by flooding. Summary of the Invention
[0003] In view of the problems existing in the prior art, the purpose of this invention is to provide a retractable anti-collision and flood control barrier suitable for limited spaces.
[0004] To solve the above problems, the present invention adopts the following technical solution: The purpose of this invention is to provide a retractable anti-collision and flood control baffle suitable for limited spaces, which can decompose the impact of floodwaters on the bottom of the river embankment, thereby reducing the impact of floodwaters on the embankment and dispersing the impact force of floodwaters to achieve stress relief. In addition, the height of the top baffle can be adjusted according to the flood height to avoid flooding damage and loss to residents, roads and buildings on the back side of the structure.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a retractable anti-collision and flood control baffle suitable for confined spaces, comprising a bottom baffle, and further comprising: A top baffle is installed above the bottom baffle. The top baffle has a U-shaped structure and is used to block floods during the flood season to ensure the flood safety of residents (same function as flood control embankment slope). Fixed columns are fixedly installed on a fixed bottom base on the side of the flood control dike slope near the river channel. The fixed columns are used for the installation of the bottom baffle and the top baffle, respectively. A rodless cylinder is fixedly installed on the inner wall of the fixed column near the top, and a top block is fixedly installed on the movable end of the rodless cylinder. A torque limiting component is installed at the middle of the inner wall of the fixed column; A synchronous positioning component is installed on the inner wall of the fixed column near the torque limiting component, and the synchronous positioning component is used to position the top baffle.
[0006] Preferably, the bottom baffle includes multiple sets of partition plates, and fixing plates are symmetrically fixedly installed at the bottom front of the fixing column. Fixing sleeves are fixedly installed at equal intervals on the outer side of the fixing plates, and elastic ropes are fixedly installed between two sets of fixing sleeves located on the same straight line.
[0007] Preferably, the partition plate near the two sets of fixing sleeves is fixedly installed on the inner side of the corresponding fixing plate, and multiple sets of partition plates are fixedly installed on the elastic rope at equal intervals. Magnetic rings are fixedly installed at equal intervals on the sides of adjacent partition plates.
[0008] Preferably, a float plate is fixedly installed at the bottom of the top baffle, a pressure plate is installed at the bottom of the float plate, and fixing blocks are fixedly installed on both sides of the back of the top baffle, with a synchronous rack fixedly installed on the back end of the fixing blocks.
[0009] Preferably, an outer protective plate is fixedly installed at the opening on the inner side of the two sets of fixed columns, and a guide groove is provided in the middle of the inner side of the outer protective plate, and the fixed block slides in the corresponding guide groove.
[0010] Preferably, a metal folding plate is fixedly installed between the fixing block and the inner wall of the guide groove, and a sliding pin is integrally formed on both sides of the metal folding plate. A sliding groove matching the sliding pin at the end of the metal folding plate is opened on both sides of the inner wall of the guide groove.
[0011] Preferably, the torsion limiting component includes a fixed plate fixedly installed on the inner wall of the fixed column, and wedge blocks are integrally formed at equal intervals on the circumference of the inner wall of the fixed plate, and arc-shaped chamfers are respectively provided on both sides of the wedge blocks.
[0012] Preferably, the synchronous positioning component includes a gear shaft rotatably mounted between the fixed column and the outer protective plate, a synchronous gear is fixedly sleeved on the outside of the gear shaft, and the synchronous gear is coplanarly arranged on the sliding path of the synchronous rack.
[0013] Preferably, a positioning ring is movably inserted inside the fixed disk, a spline sleeve is fixedly installed on the inner diameter of the positioning ring, and a spline shaft is integrally formed on the back end of the gear shaft.
[0014] Preferably, the positioning ring sleeve is slidably sleeved on the spline shaft via a spline sleeve. A spring piece is integrally formed on the circumference of the positioning ring sleeve. A slider ball is integrally formed on the end of the spring piece near the fixed plate. The slider ball is engaged between adjacent arc-shaped chamfers. A top spring is fixedly installed on the end of the spline sleeve near the inner wall of the fixed column. The top spring is located in the inner diameter of the fixed plate.
[0015] Compared with the prior art, the beneficial effects of the present invention are: In this invention, when a flood arrives, the bottom baffle is the first to come into contact with the floodwater. Multiple sets of partitions are connected in series by elastic ropes. When the flood impacts the partitions, the partitions are stressed, and the magnetic rings between adjacent partitions temporarily separate under the impact force. The elastic ropes then stretch or bend, using their elastic deformation to absorb part of the impact force of the flood. This design ensures that the bottom baffle is not a rigid whole, but rather can decompose and buffer the direct impact of the flood through the slight displacement of each partition and the elastic deformation of the elastic ropes. This effectively reduces the impact force of the flood on the bottom of the embankment and reduces the risk of the baffle being deformed and damaged due to rigid collision.
[0016] In this invention, when the flood level rises, the floating plate is subjected to upward buoyancy, which drives the top baffle to move upward as a whole. The fixing block on the back of the top baffle slides along the guide groove of the outer guard plate, and the synchronous rack rises together with the fixing block. Since the synchronous gear and the synchronous rack are coplanar and meshed, the rise of the synchronous rack drives the synchronous gear to rotate synchronously. At this time, the ball on the spring inside the positioning ring sleeve on the back of the gear shaft is released from the restriction of the arc chamfer on both sides of the wedge block. As the gear shaft rotates, it will jump over the adjacent arc chamfer one by one and be synchronously positioned at the adjustment position, thereby ensuring that the top baffle can rise smoothly to adapt to the rising water level. When the U-shaped groove in the middle of the top baffle matches the baffle of the dam railing during the rising process, it forms a complete waterproof baffle structure, thus preventing the waves from submerging the dam railing.
[0017] In this invention, the top plate baffle, through the fixing column and its torsion limiting and positioning components, U-shaped baffle, etc., can realize that the baffle does not need to be installed during non-flood seasons, and the baffle height can be flexibly adjusted according to the water level during flood seasons, so as to meet the needs of flood control safety and ecological livability.

Detailed Implementation
[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.
[0021] Example 1: This embodiment introduces a retractable anti-collision and flood control barrier suitable for confined spaces, such as... Figures 1-9 As shown, including the bottom baffle 100, it also includes: The top baffle 200 is installed above the bottom baffle 100. The top baffle 200 has a U-shaped structure and is used to block floods during the flood season to ensure the flood safety of residents (same function as flood control embankment slope). The fixing column 300 is fixedly installed on the fixed bottom base on the side of the flood control dike slope near the river channel. The fixing column 300 is used for the installation of the bottom baffle 100 and the top baffle 200 respectively. A rodless cylinder 400 is fixedly installed on the inner wall of the fixed column 300 near the top, and a top block 41 is fixedly installed on the movable end of the rodless cylinder 400. The bottom baffle 100 includes multiple sets of partition plates 11. Fixed plates 12 are symmetrically fixed at the bottom front of the fixed column 300. Fixed sleeves 13 are fixedly fixed at equal intervals on the outer side of the fixed plates 12. Elastic ropes 14 are fixedly installed between two sets of fixed sleeves 13 on the same straight line. The partition plates 11 near the two sets of fixed sleeves 13 are fixedly installed on the inner side of the corresponding fixed plates 12. Multiple sets of partition plates 11 are fixedly fixed at equal intervals on the elastic ropes 14. Magnetic rings 15 are fixedly fixed at equal intervals on the sides of adjacent partition plates 11. When a flood comes, as the water level gradually rises, it first comes into contact with the bottom baffle 100. The impact force of the flood acts on the partition plates 11. The magnetic rings 15 on the sides of adjacent partition plates 11 temporarily separate under the greater impact force, overcoming the magnetic force. The elastic ropes 14 are stretched. The partition plates 11 produce slight swings and displacements under the impact of the flood. Through the elastic deformation of the elastic ropes 14, a portion of the impact force is absorbed and buffered, realizing the initial decomposition and unloading of the impact force of the flood, and reducing the direct impact of the flood on the bottom of the dam.
[0022] The top baffle 200 has a floating plate 21 fixedly installed at its bottom, and a pressure plate 22 installed at the bottom of the floating plate 21. Fixing blocks 23 are fixedly installed on both sides of the back of the top baffle 200, and a synchronous rack 24 is fixedly installed on the back end of the fixing blocks 23. When the flood level rises, the floating plate 21 is subjected to upward buoyancy, which drives the top baffle 200 to move upward as a whole, thereby ensuring that the top baffle 200 can rise smoothly to adapt to the rising water level. When the U-shaped groove in the middle of the top baffle 200 matches the baffle of the embankment railing during the rising process, it forms a complete waterproof baffle structure, thus preventing the water waves from submerging the embankment railing.
[0023] Among them, outer protective plates 31 are fixedly installed at the openings on the inner sides of the two sets of fixed columns 300. A guide groove 311 is opened in the middle of the inner side of the outer protective plate 31. The fixed block 23 slides in the corresponding guide groove 311. Metal folding plates 32 are fixedly installed between the fixed block 23 and the inner wall of the guide groove 311. Sliding pins are integrally formed on both sides of the metal folding plate 32. Sliding grooves matching the sliding pins at the ends of the metal folding plate 32 are opened on both sides of the inner wall of the guide groove 311. The metal folding plate 32 between the fixed block 23 and the inner wall of the guide groove 311 is located at the top baffle 2. During the lifting and lowering process, the metal folding plate 32 unfolds or folds. The sliding pins on both sides of the metal folding plate 32 slide in the grooves on the inner wall of the guide groove 311, effectively blocking the opening of the guide groove 311 and preventing debris from entering the fixed column 300 and affecting the normal operation of each component. At the same time, the gear shaft 61, spline shaft 62, synchronous gear 63 and synchronous rack 24 inside the fixed column 300 are all made of rust-proof material. The overflow hole at the bottom of the fixed column 300 can drain a small amount of water inside the fixed column 300 in time, preventing these mechanical parts from being soaked inside the fixed column 300.
[0024] In this embodiment, when a flood arrives, the bottom baffle 100 comes into contact with the flood first. Multiple sets of partition plates 11 are connected in series by elastic ropes 14. When the flood impacts the partition plates 11, the partition plates 11 are stressed, and the magnetic rings 15 between adjacent partition plates 11 are temporarily separated under the impact force. The elastic ropes 14 are stretched or bent accordingly, using their elastic deformation to absorb part of the impact force of the flood. This design makes the bottom baffle 100 not a rigid whole, but can decompose and buffer the direct impact of the flood through the small displacement of each partition plate 11 and the elastic deformation of the elastic ropes 14, effectively reducing the impact force of the flood on the bottom of the embankment and reducing the risk of the baffle being deformed and damaged due to rigid collision.
[0025] In this embodiment, as Figures 4-5 As shown, the metal folding plate 32 between the fixing block 23 and the inner wall of the guide groove 311 unfolds or folds during the lifting and lowering of the top baffle 200. The sliding pins on both sides of the metal folding plate 32 slide in the groove of the inner wall of the guide groove 311, effectively blocking the opening of the guide groove 311 and preventing debris from entering the interior of the fixing column 300 and affecting the normal operation of each component. At the same time, the gear shaft 61, spline shaft 62, synchronous gear 63 and synchronous rack 24 inside the fixing column 300 are all made of rust-proof material, and the overflow hole at the bottom of the fixing column 300 can drain a small amount of floodwater inside the fixing column 300 in time, preventing these mechanical parts from being soaked inside the fixing column 300.
[0026] Example 2: Based on Example 1, this example introduces a retractable anti-collision and flood control barrier suitable for confined spaces, such as... Figures 5-9 As shown, it includes: a torsion limiting assembly 500, which is installed in the middle of the inner wall of the fixed column 300; The synchronous positioning component 600 is installed on the inner wall of the fixed column 300 near the torque limiting component 500. The synchronous positioning component 600 is used to position the top baffle 200.
[0027] The torque limiting component 500 includes a fixed plate 51 fixedly installed on the inner wall of the fixed column 300. Wedge blocks 52 are integrally formed at equal intervals on the circumference of the inner wall of the fixed plate 51. Arc-shaped chamfers 521 are respectively provided on both sides of the wedge blocks 52. The synchronous positioning component 600 includes a gear shaft 61 rotatably installed between the fixed column 300 and the outer protective plate 31. A synchronous gear 63 is fixedly sleeved on the outside of the gear shaft 61. The synchronous gear 63 is coplanarly arranged on the sliding path of the synchronous rack 24. When the flood level rises, the float 21 receives an upward buoyancy force, causing the top baffle 200 to move upward as a whole. The fixed block 2 on the back of the top baffle 200... 3. Slide along the guide groove 311 of the outer protective plate 31. The synchronous rack 24 rises together with the fixed block 23. The ball 643 on the inner spring 642 of the positioning ring sleeve 64 at the back end of the gear shaft 61 is released from the restriction of the arc chamfer 521 on both sides of the wedge block 52. As the gear shaft 61 rotates, it will jump over the adjacent arc chamfer 521 one by one and be synchronously positioned at the adjustment position, thereby ensuring that the top baffle 200 can rise smoothly to adapt to the rising water level. When the U-shaped groove in the middle of the top baffle 200 matches the baffle of the dam railing during the rising process, it forms a complete waterproof baffle structure, thus preventing the water waves from submerging the dam railing.
[0028] The fixed disk 51 has a positioning ring sleeve 64 that is movably inserted inside. A spline sleeve 644 is fixedly installed on the inner diameter of the positioning ring sleeve 64. A spline shaft 62 is integrally formed on the back end of the gear shaft 61. The positioning ring sleeve 64 is slidably sleeved on the spline shaft 62 through the spline sleeve 644. A spring piece 642 is integrally formed on the circumference of the positioning ring sleeve 64. A slider 643 is integrally formed on the end of the spring piece 642 near the fixed disk 51. The slider 643 is engaged between adjacent arc-shaped chamfers 521. A top spring 641 is fixedly installed on the end of the spline sleeve 644 near the inner wall of the fixed column 300. The top spring 641 is located in the inner diameter of the fixed disk 51. When the pressure plate 22 at the bottom of the float 21 is reduced to the initial set value by the impact of the flood, the control... When the actuator starts the rodless cylinder 400, the movable end drives the top block 41 to move downward, pressing against the synchronous rack 24. At this time, the ball 643 on the spring 642 inside the positioning ring sleeve 64 at the back end of the gear shaft 61 is released from the restriction of the wedge block 52. Under the guidance of the elastic force of the top spring 641, the positioning ring sleeve 64 can slide slightly on the spline at the back end of the gear shaft 61 through the spline sleeve 644, so that the synchronous rack 24 drives the synchronous gear 63 and the gear shaft 61 to rotate in the opposite direction, realizing the downward reset of the top baffle 200. After the rodless cylinder 400 is closed, the positioning ring sleeve 64 is reset under the action of the top spring 641, and the ball 643 is re-engaged between the wedge blocks 52, locking the gear shaft 61 and preventing the top baffle 200 from moving accidentally.
[0029] In this embodiment, as Figure 4As shown, when the flood level rises, the float 21 is subjected to upward buoyancy, which drives the top baffle 200 to move upward as a whole. The fixing block 23 on the back of the top baffle 200 slides along the guide groove 311 of the outer guard plate 31. The synchronous rack 24 rises together with the fixing block 23. Since the synchronous gear 63 and the synchronous rack 24 are coplanar and meshed, the rise of the synchronous rack 24 drives the synchronous gear 63 to rotate synchronously. At this time, the sliding ball 643 on the inner spring 642 of the positioning ring sleeve 64 at the back end of the gear shaft 61 is released from the restriction of the arc chamfer 521 on both sides of the wedge block 52. It will jump over the adjacent arc chamfer 521 one by one as the gear shaft 61 rotates and be synchronously positioned at the adjustment position. The top baffle 200 can rise smoothly to adapt to the rising water level. When the U-shaped groove in the middle of the top baffle 200 matches the baffle of the dam railing during the rising process, it forms a complete waterproof baffle structure, thus preventing the waves from submerging the dam railing.
[0030] In this embodiment, as Figures 3-7 As shown, when the pressure plate 22 at the bottom of the float 21 is reduced to the initial set value by the impact of the flood, the rodless cylinder 400 is activated by the controller. The movable end drives the top block 41 to move downward, pressing against the synchronous rack 24. At this time, the ball 643 on the spring 642 inside the positioning ring sleeve 64 at the back end of the gear shaft 61 is released from the restriction of the wedge block 52. Under the elastic guidance of the top spring 641, the positioning ring sleeve 64 can slide slightly on the spline at the back end of the gear shaft 61 through the spline sleeve 644, so that the synchronous rack 24 drives the synchronous gear 63 and the gear shaft 61 to rotate in the opposite direction, realizing the downward reset of the top baffle 200. After the rodless cylinder 400 is closed, the positioning ring sleeve 64 is reset under the action of the top spring 641, and the ball 643 is re-engaged between the wedge blocks 52, locking the gear shaft 61 and preventing the top baffle 200 from moving accidentally.
[0031] Working Principle: When this type of retractable anti-collision and flood control barrier, suitable for limited spaces, is used before floods arrive or when the water level is low, the multiple sets of partition plates 11 of the bottom barrier 100 are tightly arranged together under the natural contraction force of the elastic rope 14 and the mutual attraction of the magnetic rings 15, and are closely attached to the fixing plates 12 between the fixing columns 300, effectively reducing the occupation of river channel or embankment space. The top barrier 200, under its own weight and in its initial state under the rodless cylinder 400, is located directly above the bottom barrier 100. The overall structure is compact and does not affect daily passage or landscape effect.
[0032] When the flood arrives, as the water level gradually rises, it first comes into contact with the bottom baffle 100. The impact force of the flood acts on the partition plate 11. The magnetic rings 15 on the sides of the adjacent partition plates 11 temporarily separate under the strong impact force, overcoming the magnetic force. The elastic rope 14 is stretched, and the partition plate 11 produces a slight swing and displacement under the impact of the flood. Through the elastic deformation of the elastic rope 14, a portion of the impact force is absorbed and buffered, thus achieving the initial decomposition and unloading of the impact force of the flood and reducing the direct impact of the flood on the bottom of the dam.
[0033] As the water level continues to rise, the buoyancy of the float plate 21 gradually increases when it is submerged. When the buoyancy exceeds the weight of the top baffle 200 and its associated components, the float plate 21 causes the top baffle 200 to move upward. The fixing blocks 23 on both sides of the back of the top baffle 200 slide upward along the guide grooves 311 on the inner side of the outer protective plate 31, and the synchronous racks 24 on the back of the fixing blocks 23 also rise accordingly. Because the synchronous rack 24 meshes with the synchronous gear 63 in the synchronous positioning assembly 600, the rising of the synchronous rack 24 drives the synchronous gear 63 to rotate. The ball 643 on the spring 642 inside the positioning ring 64 at the back end of the gear shaft 61 disengages from the restriction of the arc chamfers 521 on both sides of the wedge block 52. As the gear shaft 61 rotates, it skips the adjacent arc chamfers 521 one by one and is synchronously positioned at the adjustment position. During the rising process, the U-shaped groove in the middle of the top baffle 200 matches the baffle of the embankment railing, forming a complete waterproof baffle structure, thus preventing water waves from flooding the embankment railing. During this process, the metal folding plate 32 between the fixing block 23 and the inner wall of the guide groove 311 gradually unfolds as the fixing block 23 rises. The sliding pins on both sides slide in the grooves on the inner wall of the guide groove 311, always blocking the opening of the guide groove 311 and preventing mud and sand and other debris from entering the interior of the fixing column 300.
[0034] As the flood recedes and the water level drops, the buoyancy of the float plate 21 decreases, and the water pressure felt by the pressure plate 22 decreases. When the impact force of the flood on the pressure plate 22 at the bottom of the float plate 21 decreases to the initial set value, the rodless cylinder 400 is activated by the controller. The movable end drives the top block 41 to move downward, pressing against the synchronous rack 24. At this time, the ball 643 on the spring 642 inside the positioning ring sleeve 64 at the back end of the gear shaft 61 is released from the restriction of the wedge block 52. Under the elastic guidance of the top spring 641, the positioning ring sleeve 64 can slide slightly on the spline at the back end of the gear shaft 61 through the spline sleeve 644, so that the synchronous rack 24 drives the synchronous gear 63 and the gear shaft 61 to rotate in the opposite direction, realizing the downward reset of the top baffle 200. After the rodless cylinder 400 is closed, the positioning ring sleeve 64 is reset under the action of the top spring 641, and the ball 643 is re-engaged between the wedge blocks 52, locking the gear shaft 61 and preventing the top baffle 200 from moving accidentally. After the floodwaters recede, the partition plate 11 of the bottom baffle 100 loses its impact force and, under the contraction force of the elastic rope 14 and the attraction force of the magnetic ring 15, tightly re-adheres, restoring its initial contracted state. The overflow hole at the bottom of the fixing column 300 can promptly drain any small amount of water that may have seeped into the interior during the flood, preventing internal components from rusting and being damaged due to prolonged immersion in water. Through this working process, the retractable anti-collision and flood control baffle achieves the functions of flexible extension and retraction within a limited space, effective anti-collision and flood control, and convenient storage.
