Description

Technical Field

[0001] This invention relates to the field of flood control wall technology, specifically to a mobile flood control wall with external power for rapid deployment. Background Technology

[0002] Due to the impact of global climate change, the suddenness, extreme nature, and abnormality of rainstorms and floods in my country are becoming increasingly apparent. Floods that break historical records and defy traditional understanding occur frequently, constantly raising the requirements for the height of fixed walls. However, floods are typically sudden and seasonal, especially during seasons and regions with concentrated heavy rainfall, where short bursts of intense rain can lead to the rapid formation and spread of floodwaters. Therefore, fixed walls that meet flood control requirements are often too high when not needed for water protection, impacting riverside landscapes, obstructing public views of the water, making it difficult for people to access the water, and reducing the value of urban waterfront spaces. Currently, most floodgates used for temporary heightening of fixed walls are aluminum alloy panel doors, which require manual assembly and disassembly, making rapid response during floods difficult. Furthermore, after dismantling, they need to be stored in warehouses, resulting in high storage and transportation costs. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, this invention provides an externally powered, rapidly deployable mobile flood wall. This effectively solves the problems of existing technologies, such as the sudden and severe nature of rainstorms and floods due to climate change, the excessive height of traditional fixed walls affecting waterfront landscapes and accessibility, and the need for manual disassembly and assembly, slow response, and high storage and transportation costs of existing aluminum alloy plug-in flood gates, which are difficult to meet the needs of rapid emergency deployment.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention provides an externally powered, rapidly deployable movable flood wall, comprising: a fixed wall, a frame, and a movable wall. The fixed wall has frames fixed to both sides of its top, and the movable wall is provided between the two sets of frames. The frame is equipped with a drive assembly, which includes connectors, pull ropes, fixed pulleys, reels, and a mobile power unit. The two sides of the movable wall are connected to the pull ropes through the connectors, and the upper end of the pull rope is sleeved on the outside of the fixed pulley, while the lower end of the pull rope is sleeved on the outside of the reel. When it is necessary to use the movable wall to temporarily block water, the mobile power unit indirectly drives the reel to rotate, so that part of the pull rope is wrapped around the outer wall of the reel. With the assistance of the fixed pulley, the pull rope pulls up the movable wall. The movable wall is equipped with a locking assembly on its back, which includes a gear, a locking wheel, a rack plate, and a groove. When the movable wall moves the rack plate upward, the rack plate contacts the gear and drives the gear to rotate. The gear drives the locking wheel to rotate synchronously. After the locking wheel rotates, the protruding end of the locking wheel is inserted into the groove to lock the movable wall.

[0005] Further, one end of the connecting member is fixed to the side of the movable wall, and an "open" - shaped connecting plate is sleeved outside the connecting member, and the top of the connecting plate is fixedly connected to the pulling rope.

[0006] Further, a notch is formed on the outer wall of the fixed pulley, and the pulling rope is sleeved in the notch.

[0007] Further, one end of the winding wheel is rotatably connected to the inner wall of the fixed wall, the other end of the winding wheel is fixed to the drum, belt pulleys are fixed on the outer walls of the two drums, and the outer walls of the two belt pulleys are connected by a driving belt.

[0008] Further, one end of one of the drums far from the winding wheel is connected to a connecting rod, and the connecting rod is connected to the output shaft of the mobile power unit.

[0009] Further, a storage cavity is formed at the upper end inside the frame, a rotating rod is rotatably connected to the inner wall of the storage cavity, a gear is fixed to the outer wall of the rotating rod, and a locking wheel is fixed to the front end of the rotating rod.

[0010] Further, the locking wheel is arranged in an elliptical shape, and the groove is arranged in an elliptical shape matching the locking wheel.

[0011] Further, the rack plate and the gear are arranged in the same vertical plane, and the locking wheel and the groove are arranged in the same vertical plane, so that after the movable wall moves upward, the rack plate can be accurately docked with the gear, and the locking wheel can be accurately engaged into the inside of the groove.

[0012] Further, a slot is formed at one end of the drum close to the mobile power unit, and the slot is designed in a "cross" shape, and one end of the connecting rod close to the drum is designed in a "cross" shape and inserted into the inside of the slot.

[0013] The technical solution provided by the present invention has the following beneficial effects compared with the prior art: By setting a movable wall that can be automatically lifted and an external power drive system, the present invention realizes that the flood control wall is completely stored during the non - flood season and quickly rises during the flood season, effectively taking into account the urban waterfront landscape and emergency flood control requirements; realizes a new intelligent flood control paradigm of "hidden in the scenery usually and becoming a wall during the flood season instantly". It uses a mobile power unit to drive and cooperate with synchronous belt drive, without manual intervention, and can complete deployment or reset within a few minutes, with a rapid response, completely abandoning the manual plug - in operation, significantly improving the emergency response speed and system reliability under extreme heavy rain; integrating a mechanical self - locking mechanism, locking immediately when in place, safe and reliable; the overall structure is compact, without additional storage space, significantly reducing the operation and management costs, and is especially suitable for intelligent and efficient urban flood control in scenarios of sudden heavy rainfall.

[0014] The movable wall is completely concealed within the fixed wall, providing unobstructed views during non-flood seasons and fully releasing the ecological, landscape, and public value of the waterfront space. Eliminating the need for disassembly and storage, it removes warehousing, transportation, and management costs, enabling low-carbon operation and maintenance throughout its entire lifecycle. This design deeply integrates the concepts of smart cities and resilient infrastructure, offering an efficient, intelligent, green, and people-oriented new urban flood control solution for addressing the increasingly frequent and severe sudden and extreme floods in the context of climate change. It possesses significant social and economic benefits and promising prospects for wider application. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to embodiments.

[0020] Please see Figures 1-9 This invention provides a technical solution for a mobile flood control wall with external power for rapid deployment: refer to Figure 1 and Figure 3 The device includes a fixed wall 1, a frame 12, and a movable wall 13. The fixed wall 1 has frames 12 fixed on both sides of its top, and the movable wall 13 is set between the two sets of frames 12. By integrating the movable wall 13 that can be raised and lowered on the top of the fixed wall 1, a modular flood control structure that is hidden during normal times and quickly raised during floods is realized, taking into account both urban landscape and emergency functions, and avoiding the long-term impact of traditional fixed flood control walls on daily traffic and urban appearance.

[0021] refer to Figure 3 , Figure 4 and Figure 5 The drive assembly 2, serving as the power core for the lifting and lowering of the movable wall 13, employs a flexible transmission architecture of pull rope 22 + fixed pulley 23 + reel 24, coupled with a synchronous linkage design of dual-sided drums 25, balancing structural simplification and operational stability. The two sides of the movable wall 13 are connected to the pull rope 22 via connectors 21. The pull rope 22, guided by the fixed pulley 23, winds around the outer wall of the reel 24. The power source, a mobile power unit 28, is connected to the drums 25 via connecting rods 29. The two drums 25 are synchronously driven by pulleys 26 and drive belts 27. This design eliminates the complex mechanical structure of traditional rigid transmissions, requiring no precision meshing components. This significantly reduces manufacturing costs and the difficulty and frequency of subsequent maintenance; routine checks only require checking the wear of the pull rope 22 and the belt tension to ensure normal operation.

[0022] refer to Figure 4 , Figure 5 and Figure 6The fixed pulley 23 has a specially designed notch on its outer wall as a rope groove, which can precisely constrain the position of the pull rope 22, preventing it from derailing or shifting during lifting and lowering. This ensures smooth and uniform force transmission, extending the service life of the pull rope 22 and preventing the movable wall 13 from tilting due to uneven force. The integrated design of the roller 24 and the drum 25, combined with the dual-sided synchronous transmission mechanism, ensures that the lifting speeds of the left and right sides of the movable wall 13 are completely consistent. This fundamentally avoids problems such as jamming, tilting, or sealing failure caused by asynchronous lifting and lowering, improving the reliability of the entire deployment process. At the same time, the mobile power unit 28 drives one side of the drum 25 through the connecting rod 29, and then synchronously drives the other side of the drum 25 through the synchronous transmission assembly. The synchronous transmission assembly between the drums 25 includes, but is not limited to, any one of the following: belt drive assembly, chain drive assembly, gear drive assembly, synchronous drive shaft assembly, connecting rod synchronous assembly, hydraulic synchronous circuit, pneumatic synchronous circuit, and friction wheel drive assembly. This layout achieves efficient power transmission and simplifies the overall structure of the drive system, enabling the device to flexibly adapt to fixed walls of different widths in various scenarios.

[0023] refer to Figure 2 , Figure 5 , Figure 7 and Figure 8 The locking component 3 adopts a mechanical linkage structure, seamlessly connecting the lifting and lowering action of the movable wall 13 with the locking operation, realizing a fully automatic process of "locking when in position and unlocking when lowered," without the need for additional power input or manual intervention. This component is integrated into the storage cavity 31 at the upper end of the frame 12 and consists of a gear 33, an elliptical locking wheel 34, a rack plate 35, and a matching groove 36. The rack plate 35 is fixed to the back of the movable wall 13, and the gear 33 and locking wheel 34 are coaxially fixed to the rotating rod 32 of the storage cavity 31. Furthermore, the rack plate 35 and gear 33, and the locking wheel 34 and groove 36 are all precisely aligned along the same vertical plane. This integrated layout not only makes the structure more compact but also effectively isolates it from external mud, sand, and debris, improving the component's anti-interference ability in complex flood environments and ensuring stable triggering of the locking function.

[0024] refer to Figure 7 and Figure 8The elliptical locking wheel 34 and its matching elliptical groove 36 possess a natural self-locking characteristic, allowing insertion and disengagement only at specific rotation angles. Once the protruding end of the locking wheel 34 is inserted into the groove 36, it will not loosen on its own even under the counter-pressure of floodwater, providing a highly reliable passive safety lock for the movable wall 13. When the movable wall 13 rises, the rack plate 35 moves upward and meshes with the gear 33. The continuously rising rack plate 35 drives the gear 33 to rotate, which in turn drives the locking wheel 34 to rotate synchronously until the protruding end of the locking wheel 34 is precisely inserted into the groove 36, completing the locking. When descending, the rack plate 35 moves downward, driving the gear 33 to rotate in the opposite direction, causing the locking wheel 34 to disengage from the groove 36 and automatically unlock. This design not only avoids the safety hazards caused by human negligence in not locking, but also significantly improves the structural stability in the water-blocking state, effectively resisting the lateral pressure of floodwater and preventing the movable wall 13 from accidentally falling back.

[0025] refer to Figure 4 To improve the overall durability and ease of assembly of the device, the connector 21 and various auxiliary structures all adopt targeted protective designs. One end of the connector 21 is fixed to the side of the movable wall 13, and a "U"-shaped connecting plate is sleeved on the outside. The top of the connecting plate is fixed to the pull rope 22. This structure can provide a stable force transmission path, avoiding stress concentration or local deformation caused by the pull rope 22 directly acting on the edge of the movable wall 13. At the same time, the detachable design of the connecting plate also facilitates the installation, replacement and maintenance of components in the later stage, reducing the cost of use of the equipment throughout its entire life cycle.

[0026] refer to Figure 9 The connection between the drum 25 and the connecting rod 29 adopts a cross-shaped slot 4 and plug-in structure. The cross-shaped design can efficiently transmit the torque output by the mobile power unit 28, effectively prevent slippage during transmission, and allow for a certain degree of axial assembly error, adapting to minor deviations during on-site installation and improving the convenience of construction and assembly. The integrated design of the frame 12 and the storage cavity 31 not only provides a reliable installation carrier for the drive component 2 and the locking component 3, but also protects the retracted movable wall 13 during the non-flood season from damage such as sun exposure, rain, and external impacts, thus extending the service life of the device.

[0027] During non-flood seasons or in normal operating conditions where water control is not required, the movable wall 13 is fully retracted, housed within a dedicated storage location inside the fixed wall 1. The frame 12 seamlessly integrates with the structure of the fixed wall 1, becoming an integral part of the municipal infrastructure system. At this time, the pull rope 22 in the drive assembly 2 is in a relaxed, released state, with only a small amount of rope wound around the reel 24 to maintain overall stability. The locking wheel 34 in the locking assembly 3 is in the unlocked position, disengaged from the groove 36, and the rack plate 35 is retracted into the fixed wall 1 along with the movable wall 13, without contacting the gear 33. This retractable design makes the device completely "invisible" during normal times, neither occupying urban public space nor affecting the normal passage of pedestrians and vehicles, and without disrupting the overall urban landscape. It solves the problem of traditional flood control facilities being "obtrusive and space-consuming" during normal times. Simultaneously, the movable wall 13 and its components, retracted into the fixed wall 1, effectively avoid external environmental erosion, reducing daily wear and tear and lowering maintenance frequency.

[0028] When a flood warning is received or a sudden flood or river overflow occurs, requiring the activation of the flood control wall for water protection, the device can be automatically deployed in a short time without manual operation, making it suitable for unattended scenarios such as nighttime and severe weather. The deployment process starts with the power transmission of the drive component 2. After the external mobile power unit 28 is activated, the mobile power unit 28 drives the single-sided drum 25 to rotate through the cross-shaped connecting rod 29. Since the two sets of drums 25 are linked to the drive belt 27 through the pulley 26, the rotation of the single-sided drum 25 will drive the other side drum 25 to rotate synchronously, thereby driving the two sides of the pulley 24 to start winding the pull rope 22 synchronously.

[0029] The pull rope 22 gradually tightens under the winding action of the reel 24. Guided by the fixed pulley 23 and constrained by the rope groove, the upper end transmits the tension along a fixed path to the connecting pieces 21 on both sides of the movable wall 13. Since the connecting pieces 21 are connected to the pull rope 22 via a U-shaped connecting plate, the tension is evenly distributed to the sides of the movable wall 13 through the connecting plate, avoiding deformation caused by excessive localized stress, allowing the movable wall 13 to rise smoothly under the tension. During the ascent of the movable wall 13, the rack plate 35 fixed to its back moves upward synchronously. When the movable wall 13 approaches the predetermined vertical water-blocking position, the rack plate 35 engages with the gear 33 inside the storage cavity 31 of the frame 12. As the movable wall 13 continues to rise, the rack plate 35 drives the gear 33 to rotate, and the elliptical locking wheel 34, coaxial with the gear 33, rotates synchronously.

[0030] When the movable wall 13 rises precisely to the predetermined water-blocking height, the locking wheel 34 rotates to a specific angle, and its protruding end precisely inserts into the corresponding elliptical groove 36. Mechanical locking is achieved through the self-locking property of the elliptical structure, realizing "automatic locking upon reaching the designated height" without additional operation. At this time, the movable wall 13 remains vertical, forming a continuous water-blocking barrier. The cooperative structure between the frame 12 and the movable wall 13 effectively prevents flood overflow, while the locking component 3 firmly fixes the position of the movable wall 13, resisting the lateral pressure from the flood and preventing it from tilting or accidentally falling back. The entire deployment process is rapid and can be completed in a short time, with a smooth and impact-free operation throughout, reducing the dynamic load on structural components. This ensures deployment efficiency and extends the service life of the device.

[0031] When the flood situation subsides and there is no longer a need to block water, the device can automatically reset and retract, returning to its usual concealed state. After the reset process is initiated, the mobile power unit 28 rotates in reverse, causing the drum 25 to rotate in the opposite direction. The reel 24 then releases the wound rope 22, and the movable wall 13 descends slowly under its own weight, requiring no additional power drive, thus saving energy and avoiding structural impact from forced descent. During the descent of the movable wall 13, the rack plate 35 on the back moves down synchronously, causing the meshing gear 33 to rotate in the opposite direction. The coaxial locking wheel 34 also rotates in the opposite direction, gradually disengaging from the elliptical groove 36, automatically completing the unlocking operation. The unlocking process is seamlessly integrated with the descent action, requiring no manual intervention.

[0032] Under the weight of the movable wall 13, the pull rope 22 gradually loosens, and the rope groove of the fixed pulley 23 always constrains the position of the pull rope 22 to prevent it from tangling or knotting. When the movable wall 13 is completely lowered to its storage position inside the fixed wall 1, the mobile power unit 28 stops operating, the reel 24 stops releasing the pull rope 22, and maintains a small tension to fix the position of the movable wall 13. At this time, the rack plate 35 and the gear 33 are completely disengaged, the locking wheel 34 returns to its initial unlocked position, and the entire reset process is completed. After reset, the device is reintegrated into the municipal infrastructure without affecting the daily operation of the city, and the entire process is automated, greatly reducing labor costs and operational risks.

[0033] This device specifically addresses several pain points of traditional flood control facilities, achieving a balance between flood control functionality and urban development needs. Firstly, it resolves the long-term impact of traditional fixed flood walls on the urban landscape and daily traffic. Through a design that allows for "hidden concealment during normal times and rapid deployment during floods," flood control facilities no longer occupy public space or damage the cityscape, balancing emergency protection with urban aesthetics. This makes it particularly suitable for urban core areas, scenic waterways, and other scenarios with high environmental requirements. Secondly, it overcomes the problems of low deployment efficiency and reliance on manual labor in traditional flood control facilities. Through an externally mounted mobile power unit and a fully automated process design, it eliminates the need for manual handling, assembly, or locking, providing rapid response and meeting the emergency protection needs of sudden floods while avoiding the safety risks of manual operation in severe weather.

[0034] Third, it solves the problem of insufficient structural stability under water-blocking conditions. The automatically linked mechanical locking component 3 achieves "locking upon positioning," and the self-locking characteristic of the elliptical structure effectively resists the lateral pressure of floodwaters, preventing the movable wall 13 from accidentally falling back. Compared with traditional temporary flood control sandbags, movable baffles, and other facilities, the reliability of water blocking is greatly improved. Fourth, it solves the problems of complex traditional transmission structures and high maintenance costs. The flexible transmission design of the pull rope 22 + fixed pulley 23 + winding wheel 24 and the modular component layout reduce the use of precision parts, lower manufacturing and maintenance costs, and at the same time improve the device's anti-interference ability in complex environments and extend its service life.

[0035] In addition to addressing the core flood control issue, this device also solves several derivative problems in urban flood control. First, it resolves the poor compatibility between flood control facilities and municipal infrastructure. The device is integrated into existing fixed walls (1) without requiring large-scale modifications, making it highly adaptable and flexible for different types and widths of fixed walls (1), thus reducing the overall cost of urban flood control upgrades. Second, it addresses the insufficient emergency flood control capabilities in special scenarios such as nighttime and severe weather. Deployment can be initiated remotely, effectively responding to sudden floods and filling gaps in flood control during special situations.

[0036] Third, it solves the problem of poor sealing performance and easy leakage of temporary flood control facilities. The precise positioning of the movable wall 13 during the lifting process and the reliable fixation of the locking component 3 form a tight water barrier between the movable wall 13, the frame 12, and the fixed wall 1, reducing the risk of flood leakage. At the same time, the synchronous transmission of the double-sided drum 25 drives the movable wall 13 to lift synchronously on both sides, avoiding sealing failure caused by tilting and further improving the water-blocking effect. Fourth, it solves the problem of poor assembly and maintenance convenience of flood control facilities. The cross-shaped slot 4 insertion structure of the drum 25 and the connecting rod 29, and the detachable connecting plate of the connector 21, reduce the difficulty of on-site installation and component replacement. Daily maintenance can be completed without a professional construction team, improving the practicality and promotion of the device.

[0037] This externally powered, rapidly deployable mobile flood wall, through the aforementioned design and problem-solving, brings multifaceted benefits, encompassing social, economic, and ecological advantages. In terms of social benefits, the device significantly enhances the city's emergency response capabilities to sudden floods. Its automated, rapid deployment effectively reduces the impact of floods on urban transportation, residents' lives, and public facilities, minimizing casualties and property damage caused by floods. Simultaneously, its "invisible" design protects the integrity of the urban landscape, improves the quality of life for residents, and enhances the city's resilience and disaster prevention capabilities.

[0038] In terms of economic benefits, compared to the large-scale construction and long-term maintenance of traditional fixed flood walls, this device has lower manufacturing costs and is easier to maintain, significantly reducing the total life-cycle cost of urban flood control facilities. Automated operation reduces manpower input, avoiding the high labor costs and safety risks associated with manual deployment. Simultaneously, it does not require additional public space, saving urban land resources and indirectly improving land use efficiency. In terms of ecological benefits, the device does not require large-scale modifications to the fixed wall 1 and its surrounding environment, reducing damage to the ecological environment. During non-flood seasons, its retracted state does not affect the ecological flow and landscape integrity around the river, achieving coordinated development of flood control and ecological protection.

[0039] Furthermore, the modular design and flexible adaptability of the device make it suitable not only for urban flooding and river overflow protection, but also for flood emergency response in key areas such as industrial parks, airports, and railway stations, demonstrating its wide range of applications and promotional value. Through automated and intelligent flood control solutions, this device promotes the transformation of urban flood control from "passive response" to "proactive prevention and control," providing a new technological path for the construction of urban flood control systems.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
