Description

Technical Field

[0001] This invention relates to the field of bridge pier power generation technology, specifically to a bridge pier adaptive anti-collision power generation device and control method. Background Technology

[0002] Current bridge pier collision protection devices, such as fixed fenders or floating collision boxes, only offer passive protection capabilities, have limited functionality, and cannot utilize the abundant ocean wave energy resources. Although some research in recent years has attempted to integrate wave energy generation units into collision protection devices, these typically employ external or simple embedded designs, resulting in direct exposure of the power generation devices to the environment. This exposes them to collision risks, making them susceptible to damage and difficult to maintain. Furthermore, under the complex and variable loads of waves and currents, they are prone to relative slippage or separation, affecting overall stability. In addition, existing collision protection power generation devices generally lack real-time monitoring capabilities, relying on periodic manual inspections or reactive post-incident repairs. Their low level of intelligence fails to meet the needs of refined lifecycle management for critical infrastructure.

[0003] Therefore, there is an urgent need for an integrated bridge pier adaptive anti-collision power generation device and its control method that can deeply integrate anti-collision and power generation functions in structure, ensure the coordinated operation of each component under dynamic load, and have intelligent diagnostic capabilities. Summary of the Invention

[0004] The purpose of this invention is to provide a bridge pier adaptive anti-collision power generation device and control method to solve the technical problems of anti-collision power generation devices lacking effective protection, poor stability, easy damage and difficult maintenance, lack of real-time monitoring capabilities, and low level of intelligence.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a bridge pier adaptive anti-collision power generation device, comprising: A buffer assembly, wherein the buffer assembly is disposed outside the bridge pier; A power generation component is detachably connected to the outside of the buffer component. The power generation component can move under the action of waves to convert wave energy into electrical energy. A protective component is detachably connected to the outside of the power generation component. The protective component has multiple independent and sealed chambers inside, which are filled with gas to absorb collision energy. Data acquisition units are installed in the power generation component and the protection component, respectively, to acquire air pressure data in real time; The controller is connected to the power generation component, the protection component, and the data acquisition unit via signals.

[0006] In some embodiments, the protective component includes a plurality of deformable bodies arranged closely around the outside of the power generation component and detachably connected to each other. The hollow structure in the middle of each deformable body constitutes a chamber, and the chamber is filled with gas at a certain pressure.

[0007] In some embodiments, the chambers are hexagonal in shape, and each chamber is equipped with a data acquisition device for collecting the static pressure within the chamber.

[0008] In some embodiments, the power generation assembly includes a main body and a turbine generator. A plurality of the main bodies are arranged closely around the buffer assembly in the circumferential direction and are detachably connected to each other. The space inside each main body forms an air chamber. The turbine generator is disposed on the top of the main body and the turbine of the turbine generator is disposed in the air chamber.

[0009] In some embodiments, each of the air chambers has a water inlet on the side away from the worm gear generator, and each of the air chambers is provided with a data acquisition device to collect the dynamic pressure inside the air chamber.

[0010] In some embodiments, the buffer assembly includes a plurality of elastomers arranged closely around the pier in the circumferential direction and detachably connected to each other, with the two sides of each elastomer in close contact with the pier and the power generation assembly, respectively.

[0011] In some embodiments, the anti-collision power generation device further includes connecting components for connecting the device to the bridge pier and connecting the various components.

[0012] In some embodiments, the connecting assembly includes a flexible suspension lock, a buckle, and a connecting bolt. The two ends of the flexible suspension lock are respectively connected to the buffer assembly and the pier. The two ends of the buckle are respectively connected to the buffer assembly and the power generation assembly, as well as the power generation assembly and the protective assembly. The connecting bolt is used for the internal connection of the buffer assembly, the power generation assembly, and the protective assembly.

[0013] In a second aspect, the present invention provides a control method for a bridge pier adaptive anti-collision power generation device, used to control the anti-collision power generation device provided in the first aspect of the present invention, the control method comprising the following steps: The data acquisition unit periodically and synchronously collects the air pressure values ​​in the protection components and the power generation components; The controller analyzes and judges the collected air pressure values ​​to obtain the status judgment results of the protection component and the power generation component; Damage location is determined based on the state assessment results; The controller outputs diagnostic results based on the damage location and uploads them to the remote monitoring center.

[0014] In some embodiments, the controller analyzes and judges the collected air pressure values ​​to obtain the status judgment results of the protection component and the power generation component, specifically including: If a sudden drop in air pressure is detected in the protective component and it exceeds the minimum air pressure threshold, the protective component is determined to have structural instability. If the gas pressure value in the power generation component is detected to be continuously lower than the minimum gas pressure threshold, it is determined that the power generation component has a water ingress blockage or leakage problem.

[0015] Compared with the prior art, the beneficial effects of the present invention mainly include: This invention provides an adaptive anti-collision power generation device for bridge piers. It comprises a floating annular composite structure consisting of a buffer component, a power generation component, and a protective component coaxially fitted around the bridge pier from the inside out. This deeply integrates anti-collision and power generation functions in space and along the mechanical transmission path. The outermost protective component acts as the main body for absorbing collision energy, effectively protecting the power generation component located within it. Furthermore, the two components are connected by high strength to form a stable whole, capable of jointly resisting complex marine loads. Thus, this invention overcomes the shortcomings of traditional bridge pier anti-collision power generation devices in terms of overall stability, ensuring the structural integrity and functional stability of the device during long-term service, and is particularly suitable for high-dynamic-load marine environments. Simultaneously, this invention utilizes a data acquisition device to acquire the air pressure in the power generation and protective components in real time. After analyzing and processing this air pressure data, the controller can determine the status of the power generation and protective components. This transforms the operation and maintenance mode of the entire device from a traditional passive response to an active prediction mode, significantly improving the precision of safety management and the foresight of operation and maintenance decisions, and significantly reducing the risk of sudden failures.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] The existing bridge pier anti-collision power generation devices have the following main shortcomings: 1. The anti-collision structure and the power generation structure are often simply physical superpositions. The power generation structure lacks effective protection and is prone to irreversible damage in accidents such as ship collisions, resulting in the loss of power generation function and high replacement costs. 2. The overall protection technology for complex environmental loads such as waves and water flow is insufficient. Components are prone to fatigue or loosening under long-term dynamic cyclic loads, which affects the overall rigidity and stability of the device. 3. The lack of a built-in, comprehensive structural health status perception system makes it impossible to identify the location and extent of damage to anti-collision devices in real time, or to monitor the functional status of power generation components. This creates blind spots in operation and maintenance, making predictive maintenance impossible.

[0020] To address the shortcomings of the existing technologies, this invention provides a bridge pier adaptive anti-collision power generation device and its control method. The anti-collision power generation device is a floating ring composite structure coaxially sleeved on the outside of the bridge pier, which can deeply integrate anti-collision and power generation functions in the structure, ensure collaborative operation between modules under dynamic loads, and has self-sensing and intelligent diagnostic capabilities.

[0021] like Figures 1-6As shown, a first aspect of the present invention provides a bridge pier adaptive anti-collision power generation device, including a buffer component 100, a power generation component 200, a protective component 300, a data acquisition device, and a controller. The buffer component 100 is disposed outside the bridge pier. The power generation component 200 is detachably connected to the outside of the buffer component 100 and is capable of moving under the action of waves to convert wave energy into electrical energy. The protective component 300 is detachably connected to the outside of the power generation component 200, and the protective component 300 has multiple independent sealed chambers 301 formed inside, which are filled with gas to absorb collision energy. The data acquisition device is installed in the power generation component 200 and the protective component 300 respectively, and is used to acquire air pressure data in real time. The controller is signal-connected to the power generation component 200, the protective component 300, and the data acquisition device respectively.

[0022] This invention provides an adaptive anti-collision power generation device for bridge piers. A floating annular composite structure is formed by a buffer component 100, a power generation component 200, and a protective component 300, coaxially fitted around the outside of the bridge pier from the inside out. This deeply integrates anti-collision and power generation functions in space and along the mechanical transmission path. The outermost protective component 300 acts as the main body for absorbing collision energy, effectively protecting the power generation component 200 located within it. Furthermore, the two components are connected by high strength to form a stable whole, capable of jointly resisting complex marine loads. Thus, this invention overcomes the shortcomings of traditional bridge pier anti-collision power generation devices in terms of overall stability, ensuring the structural integrity and functional stability of the device during long-term service, and is particularly suitable for high-dynamic-load marine environments. Simultaneously, this invention, through its data acquisition device, can acquire the air pressure in the power generation and protective components in real time. After analyzing and processing this air pressure data, the controller can determine the status of the power generation and protective components. In this way, the operation and maintenance mode of the entire device can be transformed from the traditional passive response to proactive prediction, significantly improving the precision of the device's safety management and the foresight of operation and maintenance decisions, and significantly reducing the risk of sudden failures.

[0023] In one preferred embodiment, the buffer assembly 100 includes a plurality of elastic bodies 110, which are closely arranged around the pier in the circumferential direction and are detachably connected to each other. The two sides of the elastic bodies 110 are in close contact with the pier and the power generation assembly 200, respectively.

[0024] In this embodiment, the elastic body 110 is made of a high-damping pneumatic tire or composite material and is in direct contact with the surface of the bridge pier. It is connected to the bridge pier by multiple sets of flexible suspension locks anchored on the elastic body 110, allowing the device to float vertically with changes in water level while limiting its horizontal displacement, avoiding rigid collisions with the bridge pier and reducing impact damage to the bridge pier.

[0025] In one preferred embodiment, the power generation assembly 200 includes a main body 210 and a turbine generator 220. A plurality of the main bodies 210 are closely arranged around the buffer assembly 100 and are detachably connected to each other by high-strength bolts. The space inside each main body 110 forms an air chamber 201. The turbine generator 220 is disposed on the top of the main body 110 and the turbine of the turbine generator 220 is disposed in the air chamber 201.

[0026] In this embodiment, each of the gas chambers 201 has a water inlet on the side away from the turbine generator 220 for seawater to enter and drive gas flow, and each of the gas chambers 201 is provided with a data acquisition device to collect the dynamic pressure inside the gas chamber 201.

[0027] In this embodiment, the turbine generator 220 is preferably a Wells turbine. The turbine of the turbine generator 220 is located in the air chamber 201, and the generator body is located outside the air chamber 201. Waves cause the water column in the air chamber 201 to move back and forth, generating bidirectional airflow to drive the turbine to rotate continuously in one direction to generate electricity.

[0028] In one preferred embodiment, the protective component 300 includes a plurality of deformable bodies 310, which are closely arranged around the outside of the power generation component 200 and are detachably connected to each other by high-strength bolts. The hollow structure in the middle of each deformable body 310 constitutes a chamber 301, which is filled with gas at a certain pressure.

[0029] In this embodiment, the chamber 301 has a regular hexagonal structure, and multiple independent and sealed chambers 301 are spliced ​​together circumferentially to form a honeycomb structure; each deformable body 310 is made of a high-toughness composite material, and each chamber 301 is equipped with a data acquisition device for collecting the static pressure inside the chamber. The deformable body 310 absorbs collision energy through controllable plastic deformation and crushing, and a single deformable body 310 can be replaced independently and quickly after damage.

[0030] In one preferred embodiment, the anti-collision power generation device further includes connecting components for connecting the device to the bridge pier and connecting the various components.

[0031] In this embodiment, the connecting assembly includes a flexible suspension lock, a buckle, and connecting bolts. The two ends of the flexible suspension lock are respectively connected to the buffer assembly 100 and the bridge pier, specifically connecting the elastic body 110 and the bridge pier. The two ends of the buckle are respectively connected to the buffer assembly 100 and the power generation assembly 200, and the power generation assembly 200 and the protective assembly 300, specifically connecting the elastic body 110 and the main body 210, and the main body 210 and the deformable body 310. The connecting bolts are used for the internal connection of the buffer assembly 100, the power generation assembly 200, and the protective assembly 300, that is, the connecting bolts are used to connect multiple elastic bodies 110, multiple main bodies 210, and multiple deformable bodies 310. The connecting bolts are high-strength bolts.

[0032] In one preferred embodiment, data acquisition devices are respectively provided in the air chamber 201 and the cavity 301. Further, the data acquisition device in the cavity 301 is located at the top center of the deformable body 310 and is used to monitor the static air pressure inside the cavity 301 in real time to determine the structural integrity of the protective component 300. The data acquisition device in the air chamber 201 is located in the non-mainstream channel area on the top side of the air chamber 201 and is installed flush with the surface. It is used to monitor the dynamic air pressure fluctuations caused by the movement of the water column inside the air chamber 201 in real time. The data acquisition device is connected to the controller through a waterproof cable.

[0033] In one preferred embodiment, the controller can be integrated into a waterproof enclosure inside the collision avoidance power generation device, including a multi-channel high-speed data acquisition card, an edge computing unit, a memory, a wireless communication module, and an independent power management unit. The controller is responsible for receiving and processing data in real time and outputting control commands and status reports.

[0034] After assembly and debugging on land, the anti-collision power generation device provided by this invention is transported to the bridge site and installed using a floating crane. Multiple sets of flexible cables or chains, evenly distributed across the continuous elastic buffer layer 3 of the device, flexibly suspend the entire device at a pre-set fixed point or pier. This connection method allows the device to rise and fall freely with water level changes and adapt to minor deformations of the bridge piers, while limiting excessive horizontal displacement, ensuring structural safety and the working posture required for power generation.

[0035] The overall size and performance parameters of the anti-collision power generation device can be flexibly configured by adding, removing, and selecting modules. The protection level is achieved by replacing anti-collision modules with different wall thicknesses and materials; the power generation capacity is adjusted by selecting power generation modules with different air chamber capacities and generator power ratings; the device diameter is directly determined by the number of circumferentially arranged modules. This design allows the same technical solution to economically and efficiently adapt to engineering needs of bridge piers with different diameters and different environmental conditions.

[0036] In addition, in this invention, the anti-collision power generation device is equipped with an independent microgrid system. A portion of the electrical energy produced by the power generation component 200 is converted by a dedicated power management circuit to continuously power the device itself, thereby achieving energy self-sufficiency and high reliability of the key system.

[0037] like Figure 7 As shown, a second aspect of the present invention provides a control method for a bridge pier adaptive anti-collision power generation device, used to control the operation of the anti-collision power generation device described in the first aspect of the present invention, comprising the following steps: Step S1: The data acquisition device periodically and synchronously collects the air pressure values ​​in the protection component 300 and the power generation component 200; Step S2: The controller analyzes and judges the collected air pressure values ​​to obtain the status judgment results of the protection component 300 and the power generation component 200; specifically including: Step S21, Status determination of protection component 300: Time series analysis is performed on each collected air pressure value to calculate the pressure change rate and stability index. If a sudden drop in air pressure value in the protective component 300 is detected and exceeds the minimum air pressure threshold or shows a continuous leakage trend, it is determined that the protective component 300 has structural instability. Step S22, Status determination of power generation component 200: For each collected air pressure value, extract the air pressure fluctuation amplitude and main frequency within the wave cycle, and evaluate the power generation activity of each turbine generator 220 in combination with known wave conditions. If the air pressure value in the power generation component 200 is detected to be continuously lower than the minimum air pressure threshold and the waveform is abnormal, it is determined that the power generation component 200 may have water ingress blockage or leakage problems. Step S3: Locate the damage based on the state judgment result; In this step, damage is located based on spatial association rules. If multiple adjacent deformable bodies 310 alarm simultaneously and the corresponding rear power generation component 200 has abnormal air pressure, it is determined that the area has suffered a serious impact, triggering an area alarm and prompting immediate shutdown and immediate repair or replacement of damaged parts. Step S4: The controller outputs diagnostic results based on the damage location and uploads them to the remote monitoring center. The diagnostic structure typically includes a health score, damaged unit ID, fault type, and maintenance priority recommendations to facilitate appropriate maintenance measures.

[0038] like Figure 8 As shown, the control method for a bridge pier adaptive anti-collision power generation device provided by the present invention has three working modes: continuous power generation and conventional monitoring mode, event-triggered enhanced monitoring mode, and fault response and degraded operation mode. Each working mode can be automatically switched under the scheduling of the controller, as detailed below: Connecting power generation and conventional monitoring modes: This is the system default mode, in which each turbine generator 220 of the wave-driven oscillating water column power generation component 200 continuously generates electricity. After the electrical energy is fed into the DC bus, it is then transmitted to the bridge deck power distribution system or energy storage device through the rising cable. At the same time, the controller's structural health status diagnosis algorithm runs at a certain period and uploads a routine status report.

[0039] Event-triggered enhanced monitoring mode: This is the response mode under general system failure. When a sudden drop in pressure or exceeding the threshold is detected in the chamber 301 of any deformable part 310 of the protection component 300, the controller immediately triggers the event response sequence: 1) Increase the sampling frequency of all data acquisition devices to the high-frequency range required for event analysis; 2) Start continuous data recording and save a snapshot of the data before and after the event; 3) Immediately execute a complete structural health status diagnosis algorithm and upload a detailed event diagnosis report first. Fault response and degraded operation mode: This is the emergency mode when the system experiences a serious fault. When the system's structural health status diagnosis algorithm confirms that a certain main body 210 of the power generation component 200 has a serious fault, the controller can remotely or automatically cut off the electrical output of the faulty module through the built-in intelligent power electronic switch, isolating it from the bus to prevent it from affecting other power generation modules or causing safety problems. The system clearly identifies the isolated module in the report and recommends repair or replacement.

[0040] When the alarm is issued, such as Figure 9 As shown, maintenance of the anti-collision power generation device is required, specifically including: 1) a maintenance vessel arriving on site with a spare module; 2) operators contacting the mechanical connections between the faulty module and adjacent modules; 3) disconnecting its electrical connectors; 4) using a ship crane to lift the faulty module as a whole; and 5) installing the new module in place. The entire process is controlled within a few hours, without the need for large floating cranes or prolonged interruption of waterways near the bridge.

[0041] In summary, the present invention provides a bridge pier adaptive anti-collision power generation device and control method, which has the following beneficial effects: 1. Achieve deep coupling between structure and function to improve overall reliability. This invention deeply integrates anti-collision and power generation functions in space and mechanical transmission path. The outer protective component 300 acts as the main body for absorbing collision energy, which effectively protects the inner power generation component 200. The two are connected by high-strength connectors to form a stable whole and jointly resist complex marine loads.

[0042] 2. Construct an intelligent health diagnosis system based on barometric pressure sensing to achieve predictive maintenance. This invention achieves real-time perception of the structural integrity and functional status of the device by monitoring the internal static pressure of the protective component 300 and the internal dynamic pressure of the power generation component 200. It transforms the operation and maintenance mode from passive response to proactive prediction, significantly improving the level of precision in safety management and the foresight of operation and maintenance decisions, and reducing the risk of sudden failures.

[0043] 3. Modular design and quick replacement mechanism significantly reduce total lifecycle costs. The standardized, independently replaceable main body 210 and deformable body 310, combined with precise quick-connect interfaces, transform maintenance operations from traditional large-scale structural disassembly and assembly to targeted operations on specific faulty units. When the monitoring system issues an alarm, maintenance personnel can directly replace the damaged module based on precise location information, without the need for large offshore construction equipment. This significantly shortens the maintenance window and facility downtime, thereby significantly reducing overall operation and maintenance costs throughout the entire lifecycle, resulting in outstanding economic benefits.

[0044] 4. Layered protection and functional decoupling enhance system resilience and post-disaster continuous service capabilities. Adopting a "damage-in-the-middle" design philosophy, the outer protective component 300 is preferentially subjected to sacrificial damage during an impact to dissipate energy, while the inner power generation component 200, due to its independent structure and water inlet channel, retains its functionality to the maximum extent. This mechanism ensures that even after partial damage to the protective component 300, the device's wave energy generation and self-sensing capabilities continue to operate, providing backup energy and status information for the bridge's basic operation and maintenance in unexpected situations, significantly enhancing the resilience and rapid recovery capabilities of critical infrastructure.

[0045] 5. Achieve on-site conversion of clean energy and energy self-sufficiency of the self-sensing system, thereby enhancing the system's autonomy. This invention directly converts captured wave energy into electrical energy, which is then prioritized to drive its built-in sensing, computing, and communication units, forming a highly efficient and reliable self-powered closed loop. This design not only reduces the bridge's dependence on the external power grid and lowers its operational carbon footprint, but more importantly, it ensures the continuous operation of core state awareness and communication functions in the event of any external power outage, adding double protection to core safety functions and demonstrating the deep integration of green energy and intelligent operation and maintenance in major engineering projects.

[0046] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
