Description

Technical Field

[0001] The present application relates to the technical field of flood control walls, and in particular to an automatically rising and falling flood control wall based on tidal energy. Background Art

[0002] Currently, global climate change has led to a continuous rise in sea levels, and coastal and estuarine areas are facing an increasingly severe threat of flood disasters. Traditional flood control measures mostly rely on fixed dams or manual monitoring and intervention, which have problems such as high construction and maintenance costs, slow response speed, and poor flexibility. Especially in areas with frequent tidal changes, fixed dams are difficult to adapt to dynamic changes in water levels, which can easily lead to waste of water resources or insufficient flood control capabilities. In addition, manual operation is limited by monitoring efficiency and emergency response capabilities, making it difficult to achieve rapid response around the clock. Therefore, there is an urgent need for an intelligent flood control device that can adapt to water level changes, respond quickly, and is energy-saving and environmentally friendly, so as to effectively improve the flood control capabilities of coastal and estuarine areas and protect people's lives and property.

The water inlet system includes a water diversion tank body, the water diversion tank body is provided with a main water inlet channel for tidal water to enter, and the water diversion tank body is provided with an auxiliary water inlet channel above the main water inlet channel; a drainage pipe is installed on the water diversion tank body, and the drainage pipe is connected to the underground tank body and is used to drain water in the water diversion tank body into the underground tank body, so that the buoyancy wall can rise under the buoyancy of the water; A guide mechanism for guiding the buoyant wall during its raising process; A locking mechanism for locking the buoyancy wall when it rises to a predetermined height; A drainage system is used to drain the water in the underground tank, causing the buoyancy wall to descend; The control center is used to control the above systems.

[0005] By adopting the above-mentioned technical solution, an underground trough, a buoyancy wall, a water inlet system, a guide mechanism, a locking mechanism, a drainage system and a control center are set up to form a flood control wall system that operates automatically based on tidal energy. It can use the natural energy of tidal fluctuations to drive the wall to rise and fall without relying on external electricity, thus realizing the combination of energy conservation and environmental protection with automated flood control. At the same time, the wall can be hidden in the underground trough and does not occupy surface space, solving the problem of traditional fixed flood control walls affecting the landscape and traffic. The overall coordination of the control center ensures the coordinated work of various systems, improving the timeliness and reliability of flood control response.

[0006] Preferably, the buoyancy wall has two layers, the inner layer is a rigid foam core layer, and the outer layer is a glass fiber reinforced plastic layer; the buoyancy wall includes a base portion and a water blocking portion, the base portion and the water blocking portion are integrally formed, the base portion is columnar, and the water blocking portion is plate-shaped; the width of the base portion is greater than the width of the water blocking portion.

[0007] By adopting the above technical solution, the buoyancy wall adopts an inner and outer layer composite structure. The inner rigid foam core layer provides sufficient buoyancy to ensure that the wall can be raised smoothly, and the outer glass fiber reinforced plastic layer gives the wall sufficient structural strength and corrosion resistance to resist the impact of tides; the one-piece molding design of the base and the water-blocking part ensures the integrity of the structure. The width of the base is greater than that of the water-blocking part. The "wide at the bottom and narrow at the top" structure reduces the water resistance during the overall lifting process of the buoyancy wall. At the same time, the larger surface area of ​​the base can provide greater buoyancy, thereby improving the lifting efficiency and stability of the buoyancy wall.

[0008] Preferably, the guiding mechanism includes A multi-track composite guide structure, the multi-guide rail composite guide structure comprising The main track is a T-shaped trough body, and there are two of them, which are respectively arranged on both sides of the length direction of the buoyancy wall. The main track is fixed to the side wall of the underground trough body, and the side of the main track is set to a T-shaped structure that can be snapped into the T-shaped trough body; Auxiliary rails, there are two groups of auxiliary rails, which are respectively arranged on both sides of the length direction of the buoyancy wall.

[0009] By adopting the above technical solution, the T-shaped groove of the main track cooperates with the T-shaped structure of the wall to limit the lateral displacement of the wall from both sides of the length direction; the cylindrical guide rail of the secondary track cooperates with the slider to limit the longitudinal shaking of the wall from both sides of the thickness direction. The two sets of tracks together form multi-dimensional constraints to ensure that the wall lifting process is smooth and without tilt, avoiding jamming or decreased water-blocking effect due to displacement, and at the same time dispersing the force on the wall and extending the service life of the guide structure.

[0011] By adopting the above technical solution, the repulsive force between the first permanent magnet bar and the second permanent magnet bar forms a magnetic levitation gap, which reduces the mechanical contact friction between the main track and the T-shaped structure of the wall, reduces the resistance during the lifting process, and makes the wall lifting smoother and more energy-efficient; at the same time, the non-contact guidance reduces component wear and maintenance frequency, and cooperates with the mechanical track to further improve the guidance accuracy and stability.

[0013] By adopting the above technical solution, when the first roller rises and falls with the wall, its spiral groove can clean the mud and sand on the surface of the main track. The spiral groove design can guide the mud and sand to both sides for discharge, which has higher cleaning efficiency and ensures the long-term stable operation of the guide mechanism. It is especially suitable for tidal environments with high sand content.

[0016] Preferably, the locking mechanism further includes An electromagnetic locking device, which is embedded in the inner wall of the top of the underground tank and locks the buoyant wall through electromagnetic force; A status sensor is connected to the electromagnetic locking device and is used to collect the locking status signal of the electromagnetic locking device and the working status signal of the electromagnet in real time; the control center establishes communication connections with the status sensor and the electromagnetic locking device respectively through a wireless network, and the control unit center receives the status signal transmitted by the status sensor to realize remote monitoring, and sends control instructions to the electromagnetic locking device to realize remote locking or unlocking control.

[0017] By adopting the above technical solution, the electromagnetic locking device serves as a supplement to the hydraulic locking, and realizes rapid locking and unlocking through electromagnetic force with a fast response speed; the status sensor provides real-time feedback on the locking status and the working status of the electromagnet. Combined with the remote communication function of the control center, remote monitoring and remote control of the locking status are realized, which improves the operational flexibility in emergency situations. The double locking design further improves the reliability of wall locking.

[0019] By adopting the above technical solution, the cyclone desander separates silt from tidal water through centrifugal force, and the filter screen intercepts fine impurities, effectively preventing silt from entering the underground tank and causing blockage or wear; the sand settling chamber collects silt, and the electronically controlled valve cooperates with the monitoring device to automatically discharge sand on a scheduled or on-demand basis, reducing manual cleaning costs; the entire desander system ensures unobstructed water inlet, extends the service life of the equipment, and ensures the stable operation of the buoyancy drive mechanism.

[0020] Preferably, ultrasonic vibration devices are provided on the main track and the auxiliary track.

[0021] By adopting the above technical solution, the ultrasonic vibration device can shake off the mud, sand and debris attached to the main track and auxiliary track through high-frequency vibration, forming a double cleaning mechanism with the cleaning roller to further prevent track jamming; the vibration effect can also reduce the probability of impurities adhering to the track surface, reduce maintenance requirements, and ensure the long-term and efficient operation of the guide mechanism.

This application incorporates an underground trough, buoyant walls, a water inlet system, a guide mechanism, a locking mechanism, a drainage system, and a control center to form a flood control wall system that automatically operates based on tidal energy. This system utilizes the natural energy of tidal fluctuations to drive the wall's rise and fall, eliminating the need for external power. This combines energy conservation and environmental protection with automated flood control. Furthermore, the wall can be concealed within the underground trough, eliminating the need for surface space. This addresses the issue of traditional fixed flood control walls impacting landscape and traffic flow. The control center's coordinated efforts ensure the coordinated operation of all systems, improving the timeliness and reliability of flood control responses. 2. This application utilizes a composite structure that balances buoyancy and strength, with a unique design that reduces water resistance and enhances sealing. A multi-track composite guide system combined with magnetic levitation assist technology constrains wall movement in multiple dimensions, reducing friction and deflection and ensuring smooth lifting and lowering. A dual locking mechanism utilizes hydraulic and electromagnetic synergy for adaptive locking and remote control, enhancing impact resistance and emergency response flexibility. Furthermore, a multi-layered anti-clogging system, including cyclonic sand removal, cleaning rollers, and ultrasonic vibration devices, effectively addresses tidal sedimentation and significantly reduces equipment wear and maintenance costs. 3. In this application, the dual protection provided by the locking mechanism is crucial. The hydraulic locking device, through adjustable locking force and pressure sensor feedback, provides dynamic resistance to tidal impact, ensuring secure locking while preventing structural overpressure damage. The electromagnetic locking device, with its rapid response, assists in securing the structure. Combined with remote monitoring and control capabilities, it enhances emergency operational flexibility. These two mechanisms work together to provide reliable dual protection, completely resolving the potential risk of displacement caused by water impact after the wall is raised. 4. In this application, optimized materials and surface technologies extend the equipment's lifespan and enhance its performance. The walls feature a sharkskin-like structure to reduce water impact, and an antibacterial coating inhibits microbial corrosion. The main rails are constructed from high-strength stainless steel for load-bearing and wear resistance, while the secondary rails utilize carbon fiber composite materials for lightweight construction. A nano-hydrophobic coating and a wear-resistant protective layer further enhance the equipment's resistance to stains and abrasion. The application of these materials and surface treatment technologies ensures the equipment's long-term adaptability to humid, sandy, and high-salt tidal environments, significantly enhancing the overall system's durability and practical value.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses an automatic lifting flood control wall based on tidal energy. Figures 1-4 The flood control wall includes an underground trough 1, a buoyancy wall 2, a water inlet system, a guide mechanism, a locking mechanism, a drainage system and a control center. Each part cooperates with each other to form a complete flood control system. Among them, the underground trough 1 is cast with C40 waterproof reinforced concrete and buried below the surface as a foundation structure. Its cross-section is rectangular and the depth is set according to local flood control needs, usually 2-5 meters. The inner wall is anti-corrosive treated by coating an epoxy resin layer to cope with the underground humid environment and water erosion. The buoyancy wall 2 is arranged in the underground trough 1 in a liftable manner. When the tide is high, it rises under the buoyancy of the water to block the tide. When the tide is low, it descends into the underground trough 1 under the action of its own weight and the drainage system, without affecting the normal traffic and landscape on the surface.

[0034] The buoyancy wall 2 utilizes a composite structure designed to balance buoyancy and structural strength. Its inner layer consists of a rigid foam core made of polyurethane with a density of ≤0.3g / cm³, providing ample buoyancy. The outer layer is a 5mm thick, glass fiber reinforced plastic layer with a tensile strength of ≥300MPa, effectively resisting tidal impact and corrosion. The two layers are bonded together using epoxy resin adhesive. The buoyancy wall 2 consists of a base portion 21 and a water-blocking portion 22, both integrally formed. The base portion 21 is columnar, wider than the water-blocking portion 22, enhancing bottom stability while also providing ample buoyancy. The water-blocking portion 22 is plate-shaped and ranges in height from 2 to 4 meters. The outer surface of the buoyancy wall 2 is pressed into a shark skin-like armor scale structure through a mold. The scale-like protrusions are 1 mm high and 3 mm apart, which can reduce the impact resistance of water flow and the deposition and adhesion of mud and sand. The surface is also coated with a 0.2 mm thick antibacterial layer, which is made of an epoxy resin base material mixed with 1% silver ions by mass, which can inhibit the growth of microorganisms and extend the service life.

[0035] The water inlet system is used to introduce tidal water into the underground trough 1 to drive the buoyancy wall 2 upward. It includes a water inlet trough 3, one end of which is connected to the external tidal water area and the other end is connected to the underground trough 1 through a drain pipe 33. The drain pipe 33 has a diameter of 20 cm and an inclination angle of 5°, and uses gravity to achieve self-flow of water. The water inlet trough 3 is equipped with a main water inlet channel 31 and an auxiliary water inlet channel 32. The main water inlet channel 31 is located on the side wall of the water inlet trough 3 near the bottom and has an internal grille to block large particles of debris. The auxiliary water inlet channel 32 is located above the main water inlet channel 31 and has the same dimensions as the main water inlet channel 31. It is used to supplement water when the tidal water level is high to ensure water inlet efficiency. A cyclone desander 8 with a processing capacity of 50-100m³ / h is installed in the water diversion trough body 3. The main water inlet channel 31 and the auxiliary water inlet channel 32 are both connected to the water inlet of the cyclone desander 8 through pipes, and the silt in the tidal water is separated by the centrifugal force of the cyclone; the water outlet of the cyclone desander 8 is connected to the drain pipe 33, and an 80-mesh stainless steel filter screen is installed at the water outlet to further filter out fine impurities; a sand settling chamber 81 is provided below the sand discharge port for collecting the separated silt, and a sand discharge port 811 is provided at the bottom of the sand settling chamber 81. A DN100 electric gate valve is installed at the sand discharge port 811 as an electric control valve 8111. The electric control valve 8111 is connected to the control center through a signal line and can be opened for sand discharge under the command of the control center. An ultrasonic level sensor is also installed in the sand settling chamber 81 as a monitoring device 812 to monitor the sediment height in real time and transmit the data to the control center so that the control center can control the opening of the electric control valve 8111 according to the sediment amount or timing instructions to prevent sediment from clogging the system.

[0036] The guide mechanism includes a multi-track composite guide structure, which includes a main track 41 and a secondary track 42. The main track 41 is a T-shaped groove body made of 304 stainless steel. There are two of them, which are fixed to the inner walls on both sides of the length direction of the underground groove body 1 by expansion bolts; the two sides of the buoyancy wall body 2 in the length direction are set as T-shaped structures that can be inserted into the T-shaped groove body to form a sliding fit. There are two groups of auxiliary rails 42, which are respectively arranged on both sides of the length direction of the buoyancy wall 2. Each group of auxiliary rails 42 includes two guide rail structures 421. The two guide rail structures 421 are respectively arranged on both sides of the thickness direction of the buoyancy wall 2. The guide rail structure 421 includes a cylindrical guide rail 4211 and a plurality of sliders 4212 slidably sleeved on the cylindrical guide rail 4211; the cylindrical guide rail 4211 is made of carbon fiber composite material with a density of 1.6g / cm³ and an elastic modulus ≥200GPa, and is fixed to the inner walls on both sides of the length direction of the underground trough 1 through a bracket; sliders 4212 are fixed at corresponding positions of the base 21 and the water-blocking part 22, and a through hole matching the cylindrical guide rail 4211 is opened in the center of the slider 4212. The slider 4212 is sleeved on the cylindrical guide rail 4211 to form a sliding fit to limit longitudinal shaking. The magnetic levitation auxiliary guide structure 5 further enhances the smoothness of guidance. It includes a first permanent magnet bar 51 and a second permanent magnet bar 52. The first permanent magnet bar 51 is embedded in the surface of the T-shaped protrusions on both sides of the buoyancy wall 2 along its length, and the second permanent magnet bar 52 is embedded in the bottom of the two T-shaped slots. The north poles of the two permanent magnet bars 51 are in opposite directions, forming a repulsive force, reducing the mechanical contact friction between the T-shaped protrusions and the main track 41. To prevent sediment accumulation from affecting guidance, a first roller 231 for cleaning sediment is rotatably mounted on the bottom of the buoyancy wall via an eccentric bearing. The outer wall of the first roller 231 contacts the surface of the main track 41 and rises synchronously with it when the buoyancy wall 2 rises. The bottom of the underground trough 1 is provided with a clearance groove for accommodating the first roller 231. The outer periphery of the first roller 231 is provided with a spiral groove, which can be used to sweep sediment on the track surface to both sides during the lifting process. In addition, ultrasonic vibration devices (not shown in the figure) are installed on the main track 41 and the auxiliary track 42 to shake off attached mud, sand and debris through high-frequency vibration, further avoiding jamming.

[0037] The locking mechanism is used to fix the buoyancy wall 2 when it rises to a predetermined height, and includes a hydraulic locking device 6. The hydraulic locking device 6 includes two groups of hydraulic cylinder groups 61 respectively arranged on both sides of the buoyancy wall 2. The hydraulic cylinder group 61 is embedded in the inner wall of the underground tank 1. The hydraulic rod end of the hydraulic cylinder in the hydraulic cylinder group 61 is provided with a locking pin 62. The locking pin 62 can be extended and pressed against the side of the buoyancy wall 2 under the drive of the hydraulic rod to achieve mechanical locking; the end of the locking pin 62 is integrated with a pressure sensor, which can monitor the ambient water pressure and the clamping force between the locking pin 62 and the buoyancy wall 2 in real time. The pressure sensor is connected to the control center signal, and the control center is driven by the two groups of hydraulic cylinder groups 61. It can adjust the hydraulic rod thrust according to the monitoring data of the pressure sensor. When the water pressure increases or the clamping force is insufficient, the hydraulic cylinder group 61 is controlled to increase the thrust; when the clamping force is too large, the thrust is reduced to protect the structure. The electromagnetic locking device 7 is embedded in the inner wall of the top of the underground trough 1, and auxiliary locking is achieved by electromagnetic force adsorbing the buoyancy wall 2; it is equipped with a status sensor, which can collect the locking status signal of the electromagnetic locking device 7 and the working status signal of the electromagnet in real time. The control center establishes communication connections with the status sensor and the electromagnetic locking device 7 through a wireless network, which can not only receive status signals for remote monitoring, but also send control instructions to achieve remote locking or unlocking, thereby improving the flexibility of emergency response.

[0038] The drainage system is used to drain the water in the underground tank body 1 when the tide goes out, so that the buoyancy wall 2 drops and resets. It mainly includes a drain outlet arranged at the bottom of the underground tank body 1, which is connected to the external low-level water body or the municipal drainage system through a pipe. An electric control valve is installed on the pipe. The electric control valve is connected to the control center signal and is controlled to open / close by the control center according to the tidal data or the water level sensor signal.

[0039] The control center, serving as the central hub for the entire system, utilizes a PLC control system and is installed in a nearby control cabinet. It connects to various systems via cables or wireless modules: It connects to the inlet system's electrically controlled valves 8111 and ultrasonic level sensors to control sand removal; it connects to the guide mechanism's ultrasonic vibration device to control its operation; it connects to the locking mechanism's pressure sensor, hydraulic cylinder assembly 61, status sensor, and electromagnetic locking device 7 to control locking; and it connects to the drainage system's electrically controlled valves to control drainage. The control center can preset tidal cycle parameters and receive external tidal monitoring signals. Based on tidal fluctuation patterns and real-time data from various sensors, it automatically coordinates the operation of the inlet, drainage, locking, and guidance systems, achieving fully automated raising and lowering and locking of the flood control wall.
