Description

Technical Field

[0001] This utility model relates to the field of gate anti-collision technology for ship locks, specifically to a ship lock gate anti-collision device that combines gravity energy dissipation with hydraulic energy dissipation. Background Technology

[0002] Ship locks are key navigation structures in water conservancy projects, and their safe operation is crucial to ensuring normal navigation after the construction of such projects. The proper opening and closing of the lock gates is essential for their safe operation. However, during lock operation, one of the most common accidents is a ship entering the lock chamber from upstream colliding with the lower lock gate. Such an accident damages both the lock gates and the ship. If not repaired promptly, it can lead to gate leakage and vibration, potentially threatening the safety of both the lock and the dam, causing lock closures, and resulting in significant economic losses and other negative impacts.

[0003] To address the issue of lock gate collisions, application number CN202410980353.6 discloses a lock gate anti-collision device and method. In this device, upon impact, the arresting chain cable across the lock chamber releases a counterweight via a winch, gradually dissipating the impact energy through gravity. This technology disperses the force generated by the collision through gravity energy dissipation, achieving collision protection. However, it still has shortcomings. First, its energy dissipation efficiency is limited by the counterweight mass, and the adjustment range is still relatively limited, potentially leading to insufficient energy dissipation when dealing with high-speed impacts from large ships. Second, the device's response speed depends on the mechanical transmission system, exhibiting a certain degree of lag and slow response. Meanwhile, application number CN202410980351.7 discloses a hydraulic energy dissipation lock gate anti-collision device and method. This device utilizes hydraulic components to improve energy dissipation efficiency and control accuracy. However, while the hydraulic response is fast, it is easily affected by the viscosity-temperature characteristics of the hydraulic fluid, resulting in unstable performance under extreme conditions.

[0004] In summary, while gravity energy dissipation is simple and reliable in structure, it has low energy dissipation efficiency and limited adjustment capability; while hydraulic energy dissipation is fast-responding and precise in control, it is easily affected by the viscosity-temperature characteristics of oil. Therefore, it is necessary to combine the two energy dissipation methods and develop an energy dissipation device that can combine the two energy dissipation methods. Utility Model Content

[0005] In view of the shortcomings of gravity energy dissipation, which is simple and reliable in structure but has low energy dissipation efficiency and limited adjustment capability, and hydraulic energy dissipation, which is fast in response and precise in control but is easily affected by the viscosity and temperature characteristics of oil, this utility model provides a ship lock gate anti-collision device that combines gravity energy dissipation and hydraulic energy dissipation, which has good performance and can combine the advantages of the two energy dissipation methods to improve the anti-collision effect.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A collision avoidance device for a ship lock gate combining gravity energy dissipation and hydraulic energy dissipation includes a gravity energy dissipation mechanism, a hydraulic energy dissipation mechanism, a pulley connection mechanism, a barrier cable, a connecting buckle, an intelligent identification mechanism, and a control center. The lock chamber is symmetrically equipped with winches and lock slots on both sides. A pontoon is installed inside each lock slot, and a fixed frame is installed on top. A hydraulic energy dissipation mechanism is installed in the lock slot above the pontoon, and a gravity energy dissipation mechanism is installed in the lock slot below it. The pulley connection mechanism includes two fixed pulleys, a movable pulley, and a wire rope. The two fixed pulleys are installed in the fixed frame. The wire rope sequentially passes around the first fixed pulley, the movable pulley, and the second fixed pulley, with one end of the wire rope connected to a winch. The winch is connected to a connecting buckle at one end; the arresting cable passes through the pontoon at both ends and is then connected to the wire rope via the connecting buckle; the bottom of the movable pulley is connected to a hydraulic energy dissipation mechanism, and a first counterweight lifting chain is also provided at the bottom; the first counterweight lifting chain passes through the pontoon and is connected to the connecting buckle, which is connected to the gravity energy dissipation mechanism, wherein the connecting buckle is locked inside the pontoon and pulls the pontoon upward during the lifting process; the intelligent identification mechanism is installed on any side of the top surface of the lock chamber and can monitor the entire operation process of the ship in the lock chamber; the control center is located in the control room of the lock and is connected to the intelligent identification mechanism, the winch, and the hydraulic energy dissipation mechanism.

[0007] Furthermore, the gravity energy dissipation mechanism includes a second counterweight lifting chain, a primary counterweight block, and a secondary counterweight block. There are two second counterweight lifting chains, which are interlocked and fixed in the middle, then connected to the connecting buckle at the end of the first counterweight lifting chain. Each second counterweight lifting chain connects to both the primary and secondary counterweight blocks. Before use, the primary and secondary counterweight blocks are submerged at the bottom of the lock chamber, and the second counterweight lifting chains are in a slack state. When the lock operation switches to the downward state, before the lock enters the lock chamber, the control center starts the winch to wind up the arresting cable lowered to the bottom of the lock chamber. When the arresting cable is raised to a height of about one meter above the water surface, it drives the pontoon to rise, and lifts the primary counterweight block through the pulley. The lifting of the primary counterweight block significantly increases the load sensor value of the winch, triggering the winch brake. At this time, the arresting cable is taut on the water surface of the lock chamber under the traction of the primary counterweight, and the entire device enters the ready state. When the intelligent identification mechanism detects that the ship is speeding, the control center starts the winch. The winch pulls the pulley upward through the connecting chain, which in turn lifts the arresting cable and buoy. As the arresting cable rises, the second counterweight lifting chain gradually tightens, first pulling the primary counterweight block upward to provide initial buffer resistance. If the ship's impact force is large and the primary counterweight block is insufficient to fully brake it, the second counterweight lifting chain continues to pull the secondary counterweight block upward, forming a stepped energy dissipation. The two second counterweight lifting chains are staggered and fixed to ensure uniform force distribution and avoid excessive force on one side that could cause structural damage, making the entire structure more stable and reliable.

[0008] Furthermore, the bottom of the movable pulley is provided with a connecting roller; the hydraulic energy dissipation structure includes an embedded platform, a hydraulic cylinder, an accumulator, and a connecting chain; the embedded platform is fixedly located in the upper part of the gate slot, and the hydraulic cylinder and accumulator are symmetrically installed on the top surface; the hydraulic cylinder is filled with hydraulic oil and has a movable piston rod, with an oil supply pipe on the side, a flow control valve in the middle of the oil supply pipe, and the end connected to the accumulator, wherein the top of the piston rod is provided with a connecting wheel; the flow control valve is also connected to a receiver, and the receiver is wirelessly connected to the control center; the connecting chain respectively wraps the connecting roller and the connecting wheel to form a closed transmission mechanism. The control center controls the flow rate of hydraulic oil by adjusting the opening and closing of the flow control valve. When the valve is closed, the hydraulic oil flow is small, resulting in high hydraulic energy; when the valve is closed, the hydraulic oil flow is large, resulting in low hydraulic energy. When the speed is high, a signal is transmitted to the control center. Upon receiving abnormal information, the control center issues a command via wireless signal. The receiver adjusts the flow control valve, specifically reducing the flow rate of hydraulic oil and increasing the hydraulic energy dissipation value. At this point, the gravity energy dissipation mechanism and the hydraulic energy dissipation mechanism work together to intercept and dissipate energy. After the ship hits the arresting cable, the arresting cable is subjected to force to intercept, and the traction pulley continues to rise. During this process, the traction pulley pulls the connecting roller, which in turn drives the connecting chain, connecting wheel, and... The piston rod moves upward, forcing the hydraulic oil out of the hydraulic cylinder. The hydraulic oil then passes through a flow control valve and enters the accumulator. This process consumes energy, thus successfully preventing the ship from colliding with the gate. The energy consumption process converts the kinetic energy generated by the ship's impact into the pressure energy and heat energy of the hydraulic oil. The hydraulic cylinder and the accumulator are connected by an oil pipeline, working together to achieve dynamic adjustment. The control center adjusts the hydraulic damping force in real time via wireless signals, significantly improving the response speed and energy dissipation efficiency. The closed transmission mechanism formed by the connecting chains ensures stable and reliable energy transmission. It can quickly activate the hydraulic energy dissipation mechanism during a ship collision, retaining the reliability of gravity energy dissipation while leveraging the precise controllability of hydraulic energy dissipation. This effectively solves the problems of insufficient efficiency or delayed response of a single energy dissipation method.

[0009] Furthermore, the embedded platform is embedded in the wall of the lock slot on three sides, with a certain distance left between the fourth side and the lock chamber wall for the arresting cable to pass through. The embedded platform also has a connecting hole corresponding to the first counterweight lifting chain, which extends downwards through the connecting hole. Embedding the three sides of the embedded platform into the lock slot wall ensures structural stability while reserving space for the arresting cable and counterweight lifting chain, effectively preventing motion interference. The arresting cable passes through the gap between the platform and the lock slot, and the counterweight lifting chain extends smoothly downwards through the connecting hole, ensuring the normal operation of the gravity energy dissipation mechanism. The hydraulic energy dissipation mechanism and the gravity energy dissipation system work together without interference. The embedded installation of the platform enhances structural strength, enabling it to withstand greater impact loads, while the reserved channel ensures a rapid response from the arresting system, improving the reliability and practicality of the anti-collision device.

[0010] Furthermore, the hydraulic energy dissipation structure also includes a hinged platform. The top surface of the hinged platform is fixedly connected to the hydraulic cylinder and the accumulator, while the bottom surface is movably connected to the embedded platform. The hinged platform can drive the entire hydraulic energy dissipation mechanism to hinge, allowing the hydraulic cylinder to adaptively deflect according to the pulling direction of the movable pulley, maintaining the axial force state of the piston rod.

[0011] Furthermore, the intelligent identification mechanism includes a fixed rod and an electrically connected camera, radar speedometer, microcontroller, wireless communication module, and storage module. The fixed rod is fixedly installed on any side of the top surface of the lock chamber, with the camera and radar speedometer installed near the top of the fixed rod. The microcontroller, wireless communication module, and storage module are embedded inside the fixed rod, with the wireless communication module wirelessly connected to the control center. The storage module contains the ship's normal operating speed data and also stores relevant data from the camera, radar speedometer, and microcontroller. The monitoring data from the camera and radar is transmitted to the microcontroller, which receives, analyzes, and processes the ship's operating data, comparing it with the normal operating speed stored in the storage module. When the received ship speed exceeds a preset speed, it indicates an overspeeding phenomenon. At this time, the microcontroller sends the overspeeding information to the control center via the wireless communication module, and the control center activates the device. By monitoring the ship's speed in real time through the camera and radar speedometer and automatically judging the overspeeding situation based on the preset data, abnormal ships can be detected in a timely manner, facilitating rapid response and activation of the device.

[0012] Furthermore, the control center includes an electrically connected transceiver and controller, both installed in the control room. The controller employs a 32-bit MCU, such as the STM32F7 series microcontroller. The transceiver receives the ship's operating speed monitored by the intelligent identification mechanism and transmits abnormal data to the controller when the speed is abnormal. The controller analyzes the returned data and then issues control commands, which are sent to the winch and hydraulic energy dissipation mechanism via the transceiver. The winch and hydraulic energy dissipation mechanism then commence operation. The controller, in conjunction with the wireless transceiver, enables high-speed processing of intelligent identification data and precise transmission of control commands. It can also quickly activate the winch and hydraulic energy dissipation mechanism based on real-time monitoring data, ensuring timely response of the anti-collision device when the ship exceeds its speed limit, effectively solving the problem of lag in traditional control systems.

[0013] Furthermore, the pontoon has an internal through-hole that is wider in the middle and narrower at both ends, and a notch on the side. The first counterweight passes through the through-hole. The diameter of the through-hole in the middle is larger than that of the connecting buckle, while the diameters at both ends are smaller than those of the connecting buckle, thus confining the connecting buckle within the through-hole. A reversing shaft is located in the middle of the notch, and the arresting cable enters the notch and rotates around the reversing shaft. The design of the through-hole being wider in the middle and narrower at both ends allows the connecting buckle at the end of the first counterweight lifting chain to move freely inside the through-hole without detaching from it, ensuring that the pontoon can move upwards during subsequent lifting. The structure is reasonable and reliable.

[0014] How to use: When the lock operation mode is switched to the downward state, before the lock enters the lock chamber, the control center starts the winch to wind up, causing the arresting cable placed at the bottom of the lock chamber to rise. When the arresting cable is raised to a height of about one meter above the water surface, the arresting cable drives the pontoon to rise together, and drives the gravity energy dissipation mechanism to rise, which causes the load sensor value of the winch to increase significantly, thereby triggering the winch to brake. At this time, the arresting cable is taut on the water surface of the lock chamber under the traction of the gravity energy dissipation mechanism, and the whole device enters the ready state.

[0015] In operation, the intelligent identification mechanism continuously monitors the speed of ships within the lock chamber. When the intelligent identification mechanism detects abnormal ship speed, such as overspeeding or loss of control, it transmits a signal to the control center. The control center then activates the winch, which pulls the pulley upwards via a steel cable, thereby lifting the gravity energy dissipation mechanism and the pontoon. At this point, the pontoon and arresting cable are raised from the seabed to above the water surface, forming the first buffer barrier. After the ship collides with the arresting cable, the arresting cable is forced to intercept it, pulling the pulley upwards. The rising pulley drives the gravity energy dissipation mechanism and the hydraulic energy dissipation mechanism to consume the kinetic energy generated by the impact until the ship is intercepted, thus preventing the lock gate from being hit. After successful interception, the winch releases the steel cable, and the arresting cable, pontoon, and counterweight return to their initial positions. The control center can dynamically adjust the hydraulic energy dissipation mechanism according to the real-time speed of the ship to facilitate control of hydraulic energy dissipation. The control center of the device determines whether the hydraulic energy dissipation mechanism should participate in the energy dissipation work based on the ship's kinetic energy. When the ship's speed is normal, the generated ship kinetic energy is less than or equal to the gravitational potential energy that the gravity energy dissipation mechanism can provide. Therefore, the hydraulic energy dissipation mechanism does not start, and only the gravity energy dissipation mechanism works in the entire device. Otherwise, the hydraulic energy dissipation mechanism participates in the work.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. This utility model combines the advantages of gravity energy dissipation and hydraulic energy dissipation. Through an intelligent identification system, it monitors the ship's speed in real time, and the control center coordinates with the winch to quickly lift the arresting cable to form multi-level protection. The gravity energy dissipation mechanism provides basic protection, while the hydraulic energy dissipation mechanism achieves dynamic adjustment. The synergistic effect of the two significantly improves energy dissipation efficiency and response speed. When dealing with collisions from ships of different tonnages, the device can ensure both rapid response and stable performance, effectively solving the problems of insufficient energy dissipation and delayed response in existing technologies, and providing more reliable collision protection for lock gates.

[0017] 2. This utility model monitors the ship's speed in real time through an intelligent identification mechanism, and combines radar and camera data to quickly determine whether it is speeding and trigger a response from the control center. The control center uses a high-performance controller, which can process data quickly while ensuring that instructions are issued accurately and in a timely manner. The gravity energy dissipation mechanism adopts a double-stage counterweight block and staggered lifting chain design to achieve stepped energy dissipation, improve the buffering effect and structural stability. The special through-hole design of the buoy box allows the connecting buckle to move flexibly and not fall off, ensuring the effective operation of the arresting cable.

[0018] 3. The hydraulic energy dissipation structure of this utility model can be adjusted by regulating the flow control valve in the control center, which can convert the kinetic energy of the ship impact into the pressure energy and heat energy of the hydraulic oil, thereby improving the energy dissipation efficiency. The articulated platform design enables the hydraulic cylinder to adapt to the direction of the pulling force, maintain the axial force on the piston rod, and enhance the system response speed and stability. The hydraulic energy dissipation mechanism and the gravity energy dissipation mechanism work together, which has both reliability and controllability, effectively solves the problems of low efficiency and slow response of the single method, and significantly improves the collision prevention capability of the lock.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] Example 1: A ship lock gate anti-collision device combining gravity energy dissipation and hydraulic energy dissipation, comprising a gravity energy dissipation mechanism 1, a hydraulic energy dissipation mechanism 2, a pulley connection mechanism 3, a barrier cable 4, a connecting buckle 5, an intelligent identification mechanism 6, and a control center. A winch 7 and a lock slot are symmetrically arranged on both sides of the lock chamber. A pontoon 8 is provided inside the lock slot, and a fixed frame 9 is provided on top. The hydraulic energy dissipation mechanism 2 is installed in the lock slot above the pontoon 8, and the gravity energy dissipation mechanism 1 is installed in the lock slot below. The pulley connection mechanism 3 includes two fixed pulleys 31, a movable pulley 32, and a wire rope 33. The two fixed pulleys 31 are installed in the fixed frame 9. The wire rope 33 sequentially passes over the first fixed pulley 31, the movable pulley 32, and the second fixed pulley 31. One end of the cable is connected to the winch 7, and the other end is connected to the connecting buckle 5. The two ends of the arresting cable 4 pass through the pontoon 8 and are then connected to the wire rope 33 via the connecting buckle 5. The bottom of the movable pulley 32 is connected to the hydraulic energy dissipation mechanism 2, and a first counterweight lifting chain 34 is also provided at the bottom. The first counterweight lifting chain 34 passes through the pontoon 8 and is connected to the connecting buckle 5. The connecting buckle 5 is connected to the gravity energy dissipation mechanism 1. The connecting buckle 5 is locked inside the pontoon 8 and pulls the pontoon 8 up during the lifting process. The intelligent identification mechanism 6 is installed on any side of the top surface of the lock chamber and can monitor the entire operation process of the ship in the lock chamber. The control center is located in the control room of the lock and is connected to the intelligent identification mechanism 6, the winch 7, and the hydraulic energy dissipation mechanism 2.

[0028] How to use: When the lock operation mode is switched to the downward state, before the lock enters the lock chamber, the control center starts the winch 7 to wind up, causing the arresting cable 4 placed at the bottom of the lock chamber to rise. When the arresting cable 4 is raised to a height of about one meter above the water surface, the arresting cable 4 drives the float box 8 to rise together, and drives the gravity energy dissipation mechanism 1 to rise, which makes the load sensor value of the winch 7 increase significantly, thereby triggering the winch 7 to brake. At this time, the arresting cable 4 is taut on the water surface of the lock chamber under the traction of the gravity energy dissipation mechanism 1, and the whole device enters the ready state.

[0029] In operation, the intelligent identification mechanism 6 continuously monitors the speed of ships within the lock chamber. When the intelligent identification mechanism 6 detects abnormal ship speed, such as overspeeding or loss of control, it transmits a signal to the control center. The control center then activates the winch 7, which pulls the pulley 32 upward via the wire rope 33, thereby lifting the gravity energy dissipation mechanism 1 and the pontoon 8. At this point, the pontoon 8 and the arresting cable 4 are raised from the bottom of the water to above the surface, forming the first buffer barrier. After the ship collides with the arresting cable 4, the arresting cable is forced to intercept, pulling the pulley 32 to continue rising. The rising pulley 32 drives the gravity energy dissipation mechanism 1 and the hydraulic energy dissipation mechanism 2 to dissipate the kinetic energy generated by the impact until the ship is intercepted, thus preventing the lock gate from being hit. After successful interception, the winch 7 releases the wire rope 33, and the arresting cable 4, pontoon 8, and counterweight return to their initial positions. The control center can dynamically adjust the hydraulic energy dissipation mechanism 2 according to the real-time speed of the ship to facilitate the control of hydraulic energy dissipation. The control center of the device determines whether the hydraulic energy dissipation mechanism 2 participates in the energy dissipation work based on the ship's kinetic energy. When the ship's speed is normal, the generated ship kinetic energy is less than or equal to the gravitational potential energy that the gravity energy dissipation mechanism 1 can provide. Therefore, the hydraulic energy dissipation mechanism 2 does not start, and only the gravity energy dissipation mechanism 1 works in the entire device. Otherwise, the hydraulic energy dissipation mechanism 2 participates in the work.

[0030] Example 2: The difference from Example 1 is that the gravity energy dissipation mechanism 1 includes a second counterweight lifting chain 11, a primary counterweight block 12 and a secondary counterweight block 13; there are two second counterweight lifting chains 11, which are fixed in a staggered manner in the middle, and then connected to the connecting buckle 5 at the end of the first counterweight lifting chain 34, wherein each second counterweight lifting chain 11 is connected to the primary counterweight block 12 and the secondary counterweight block respectively. With the first-stage counterweight 12 and the second-stage counterweight 13 submerged at the bottom of the lock chamber, and the second counterweight lifting chain 11 in a slack state, when the lock operation switches to the downward state, before the lock enters the lock chamber, the control center starts the winch 7 to wind up, causing the arresting cable 4, which is placed at the bottom of the lock chamber, to rise. When the arresting cable 4 is raised to a height of about one meter above the water surface, the arresting cable 4 drives the pontoon 8 to rise together, and lifts the first-stage counterweight 12 through the pulley 32. The lifting of the first-stage counterweight 12 causes a significant increase in the load sensor value of the winch 7, triggering the winch 7 to brake. At this time, the arresting cable 4 is taut on the water surface of the lock chamber under the traction of the first-stage counterweight 12, and the entire device enters the ready state. When the intelligent identification mechanism 6 detects that the ship is speeding, the control center starts the winch 7. The winch 7 pulls the pulley 32 upward through the connecting chain 24, which drives the arresting cable 4 and the buoy 8 to rise. As the arresting cable 4 rises, the second counterweight lifting chain 11 gradually tightens, first pulling the first-level counterweight block 12 upward to provide initial buffer resistance. If the ship's impact force is large and the first-level counterweight block 12 is insufficient to fully brake, the second counterweight lifting chain 11 continues to pull the second-level counterweight block 13 upward, forming a stepped energy dissipation. The two second counterweight lifting chains 11 are staggered and fixed to ensure uniform force distribution and avoid excessive force on one side, which could lead to structural damage and make the entire structure more stable and reliable.

[0031] The float 8 has a through hole 81 that is wider in the middle and narrower at both ends, and a notch 82 on the side. The first counterweight passes through the through hole 81. The diameter of the middle part of the through hole 81 is larger than that of the connecting buckle 5, while the diameters at both ends are smaller than that of the connecting buckle 5, thus confining the connecting buckle 5 within the through hole 81. A reversing shaft 83 is located in the middle of the notch 82. After the arresting cable enters the notch 82, it reverses around the reversing shaft 83. The design of the through hole 81, which is wider in the middle and narrower at both ends, allows the connecting buckle 5 at the end of the first counterweight lifting chain 34 to move freely inside the through hole 81 without detaching from it. This ensures that the float 8 can move upward during subsequent lifting, making the structure reasonable and reliable.

[0032] Example 3: Unlike Example 1, the bottom of the movable pulley 32 is provided with a connecting roller; the hydraulic energy dissipation structure includes an embedded platform 21, a hydraulic cylinder 22, an accumulator 23, and a connecting chain 24; the embedded platform 21 is fixedly located in the upper part of the gate slot, and the hydraulic cylinder 22 and the accumulator 23 are symmetrically installed on the top surface; the hydraulic cylinder 22 is filled with hydraulic oil and has a movable piston rod 29, with an oil supply pipe 25 on the side, a flow control valve 26 in the middle of the oil supply pipe 25, and the end connected to the accumulator 23, wherein the top of the piston rod 29 is provided with a connecting wheel 210; the flow control valve 26 is also connected to a receiver 27, and the receiver 27 is wirelessly connected to the control center; the connecting chain 24 respectively wraps the connecting roller and the connecting wheel 29 to form a closed transmission mechanism. The control center controls the flow rate of hydraulic oil by controlling the opening and closing of the flow control valve 26. When the valve is closed, the flow rate of hydraulic oil is small, and the hydraulic energy generated is large; when the valve is closed, the flow rate of hydraulic oil is large, and the hydraulic energy generated is small. When the speed is high, a signal is transmitted to the control center. When the control center receives abnormal information, it issues a command via wireless signal. After receiving the signal, the receiver 27 adjusts the flow control valve 26, specifically by reducing the flow rate of hydraulic oil, thus increasing the hydraulic energy dissipation value. At this time, the gravity energy dissipation mechanism 1 and the hydraulic energy dissipation mechanism 2 jointly participate in interception and energy dissipation. After the ship hits the arresting cable 4, the arresting cable is subjected to force to intercept, and the traction pulley 32 continues to rise. During this process, the traction pulley 32 pulls the connecting roller, which drives the connecting chain 24 and the connecting wheel 210 to... As the piston rod 29 moves upward, it forces the hydraulic oil out of the hydraulic cylinder 22. The hydraulic oil then passes through the flow control valve 26 and enters the accumulator 23. This process consumes energy, thus successfully preventing the ship from colliding with the gate. The energy consumption process converts the kinetic energy generated by the ship's impact into the pressure energy and heat energy of the hydraulic oil. The hydraulic cylinder 22 and the accumulator 23 are connected by the oil supply pipe 25 to achieve dynamic adjustment. The control center adjusts the hydraulic damping force in real time via wireless signal, significantly improving the response speed and energy dissipation efficiency. The closed transmission mechanism formed by the connecting chain 24 ensures stable and reliable energy transmission. It can quickly activate the hydraulic energy dissipation mechanism 2 when the ship collides, retaining the reliability of gravity energy dissipation while giving full play to the precise controllability of hydraulic energy dissipation, effectively solving the problem of insufficient efficiency or delayed response of a single energy dissipation method.

[0033] The control center includes an electrically connected transceiver and controller, both installed in the control room. The controller uses a 32-bit MCU, such as an STM32F7 series microcontroller. The transceiver receives the ship's operating speed monitored by the intelligent identification mechanism 6 and transmits abnormal data to the controller when the speed is abnormal. The controller analyzes the returned data and then issues control commands, which are sent to the winch 7 and hydraulic energy dissipation mechanism 2 via the transceiver. The winch 7 and hydraulic energy dissipation mechanism 2 then begin operation. The controller, in conjunction with the wireless transceiver, enables high-speed processing of intelligent identification data and precise transmission of control commands. It can also quickly activate the winch 7 and hydraulic energy dissipation mechanism 2 based on real-time monitoring data, ensuring timely response of the anti-collision device when the ship exceeds its speed limit, effectively solving the problem of lag in traditional control systems.

[0034] Example 4: Unlike Example 3, the embedded platform 21 is embedded in the wall of the lock slot on three sides, with a certain distance between the fourth side and the lock chamber wall for the arresting cable 4 to pass through. The embedded platform 21 also has a connecting hole corresponding to the first counterweight lifting chain 34, which extends downwards through the connecting hole. Embedding the embedded platform 21 on three sides into the lock slot wall ensures structural stability while reserving space for the arresting cable 4 and the counterweight lifting chain, effectively preventing motion interference. The arresting cable 4 passes through the gap between the platform and the lock slot, and the counterweight lifting chain extends smoothly downwards through the connecting hole, ensuring the normal operation of the gravity energy dissipation mechanism 1. The hydraulic energy dissipation mechanism 2 and the gravity energy dissipation system work together without interference. The embedded installation of the embedded platform 21 enhances structural strength, enabling it to withstand greater impact loads, while the reserved channel ensures a rapid response from the arresting system, improving the reliability and practicality of the anti-collision device.

[0035] The hydraulic energy dissipation structure also includes a hinged platform 28, with a hydraulic cylinder 22 and an accumulator 23 fixedly connected to the top surface of the hinged platform 28, and the bottom surface movably connected to the embedded platform 21. The hinged platform 28 can drive the entire hydraulic energy dissipation mechanism 2 to hinge, so that the hydraulic cylinder 22 can adaptively deflect according to the pulling direction of the pulley 32, maintaining the axial force state of the piston rod.

[0036] The intelligent identification mechanism 6 includes a fixed rod and an electrically connected camera, radar speedometer, microcontroller, wireless communication module, and storage module. The fixed rod is fixedly installed on any side of the top surface of the lock chamber, with the camera and radar speedometer installed near the top. The microcontroller, wireless communication module, and storage module are embedded inside the fixed rod, with the wireless communication module wirelessly connected to the control center. The storage module contains the ship's normal operating speed data and also stores relevant data from the camera, radar speedometer, and microcontroller. The monitoring data from the camera and radar is transmitted to the microcontroller, which receives, analyzes, and processes the ship's operating data, comparing it with the normal operating speed stored in the storage module. If the received ship speed exceeds a preset speed, it indicates an overspeeding phenomenon. At this time, the microcontroller sends the overspeeding information to the control center via the wireless communication module, and the control center activates the device.
