Description

Technical Field

[0001] This invention relates to the field of dock facilities technology, specifically to a ship berthing force alarm mechanism. Background Technology

[0002] In a busy large port, a large number of ships of different tonnages and types enter and leave every day. As a key facility to ensure the safe berthing of ships, the port's berthing piers face enormous challenges in the frequent berthing operations. Traditional berthing piers lack effective force monitoring and alarm mechanisms, which exposes many serious problems in the operation of large ports.

[0003] Because it is impossible to monitor the force exerted on the berths by ships in real time, port staff find it difficult to determine whether the load on the berths is within a safe range. In large ports, large container ships frequently berth. These ships are enormous, and the impact force generated when berthing is extremely large. If the berths are subjected to forces exceeding their design load-bearing capacity for a long period, structural damage will gradually occur. Once the berths are severely damaged, their stability will be affected, potentially leading to unsafe situations such as swaying and drifting when ships berth, or even preventing ships from berthing normally, delaying loading and unloading times, affecting the normal use of the terminal, and causing huge economic losses to port operations.

[0004] Therefore, we have made improvements to this and proposed a ship berthing force alarm mechanism and its implementation method. Summary of the Invention

[0005] To address the technical problems existing in the background art, the present invention proposes a ship berthing force alarm mechanism.

[0006] The present invention proposes a ship berthing force alarm mechanism, which includes a berthing block body, and a force-bearing block connected to the side of the berthing block body through a buffer assembly. The distance between the berthing block body and the force-bearing block is adjustable under the ship's force.

[0007] A chute is provided on the side of the pier body closest to the stress block, and a warning device that can slide upwards towards the pier body is installed inside the chute.

[0008] A transmission assembly is installed between the pier body and the force-bearing block. The movable end of the transmission assembly extends into the slide groove and is connected to the lower end of the warning device. The force exerted by the ship on the force-bearing block is converted into the lifting and lowering driving force of the warning device through the transmission assembly.

[0009] In dock operations, the magnitude of the force exerted on the berth when a ship docks is difficult to visually assess, potentially leading to damage. This invention addresses this issue by connecting the berth body and the load-bearing block with a buffer assembly. When the ship applies force as it docks, the distance between the two changes, providing initial buffering. A chute provides a sliding track for the warning device, allowing it to move regularly on the berth body. The transmission assembly is the key force conversion component, cleverly transforming the horizontal force exerted on the load-bearing block by the ship into a vertical lifting and lowering driving force for the warning device. Thus, when a ship docks, staff can visually understand the force exerted on the berth through the raising and lowering of the warning device, detect potential dangers in advance, prevent damage to the berth due to excessive force, and ensure the safety of dock facilities and the normal operation of ship berthing.

[0010] As a further optimized solution of the present invention, the transmission assembly includes transmission units symmetrically distributed on both sides of the warning device. The transmission unit includes a sliding plate, a fixing block and a connecting frame. The sliding plate is slidably assembled in the groove and is in transmission cooperation with the lower end of the warning device. The fixing block is fixedly installed on the opposite surface of the force-bearing block and the berthing block body. The two ends of the connecting frame are rotatably connected to the sliding plate and the fixing block respectively.

[0011] The transmission assembly adopts a symmetrically distributed transmission unit design, which enhances the stability and reliability of the structure. The fixed block is fixed on the opposite surface of the force-bearing block and the berthing pier, ensuring that the entire transmission structure moves synchronously with the force-bearing block. The two ends of the connecting frame are rotatably connected to the sliding plate and the fixed block, respectively. When the force-bearing block moves, the connecting frame can flexibly change its angle, driving the sliding plate to slide smoothly in the slide groove. The sliding plate and the lower end of the warning device are connected by a transmission, which accurately converts the horizontal sliding of the sliding plate into the lifting and lowering motion of the warning device, so that the force of the ship berthing can be stably transmitted and converted into a warning signal, ensuring that the alarm mechanism works accurately.

[0012] Furthermore, the two connecting frames are symmetrically distributed to form a figure-eight shape, with the upper opening of the figure-eight shape facing the slide groove and the lower opening facing the force-bearing block;

[0013] The two connecting frames are arranged in a figure-eight shape. This unique structure optimizes the force transmission path. When the load-bearing block moves under the force of the ship, the figure-eight connecting frame can better convert the horizontal displacement of the load-bearing block into an effective pushing force on the sliding plate. Since the upper opening of the figure-eight faces the chute and the lower opening faces the load-bearing block, the connecting frame can push the sliding plate upward at a more reasonable angle as the load-bearing block approaches the berthing pier. This improves the transmission efficiency and ensures that the warning device can respond to the force of the ship approaching the shore in a timely and accurate manner, and rise steadily to issue a warning.

[0014] Furthermore, a movable block is installed at the lower end of the warning device, and a drive block is installed at the upper end of the slide plate. The sides of the movable block and the drive block that are close to each other are both inclined surfaces, and the two inclined surfaces are parallel to each other and are slidably assembled.

[0015] The inclined surface design of the movable block and the drive block is a key element in the transmission process. When the slide plate slides horizontally under the drive of the connecting frame, the drive block moves with the slide plate. Since the two inclined surfaces are parallel to each other and slidably assembled, the horizontal movement of the drive block will generate an upward component force along the inclined surface of the movable block, thereby pushing the movable block and the connected alarm upward. This inclined surface design cleverly transforms the horizontal movement of the slide plate into the vertical upward movement of the alarm, and the sliding fit between the inclined surfaces can effectively buffer the possible impact force, making the transmission process smoother and improving the stability of the alarm mechanism.

[0016] Furthermore, the movable block is an isosceles trapezoidal block that is wider at the top and narrower at the bottom. T-shaped blocks are installed at the top of both sides of the movable block. A T-shaped groove that matches the T-shaped block is opened on the inclined surface of the drive block. The movable block and the drive block are slidably assembled through the T-shaped block and the T-shaped groove.

[0017] The isosceles trapezoidal design of the movable block and the cooperation of the T-shaped block and T-slot further optimize the connection and transmission effect between the movable block and the drive block. The isosceles trapezoidal movable block can ensure that the force is more even when it is in contact with the inclined surface of the drive block, avoiding movement jamming or deviation caused by uneven force.

[0018] The sliding assembly method of the T-block and T-slot not only restricts the relative movement direction between the moving block and the driving block, making them slide only in a specific direction, but also enhances the connection stability between the two, preventing separation or misalignment when the ship docks and generates a large impact force, ensuring the reliability and accuracy of the transmission process, and guaranteeing the stable operation of the alarm mechanism.

[0019] As a further optimization of the present invention, the upper end of the pier body is provided with a through hole that is connected to the sliding groove and adapted to the upper end of the warning device. Under the driving action of the transmission component, the upper end of the warning device slides upward along the through hole towards the upper part of the pier body.

[0020] The through hole provides guidance and limit for the upward movement of the alarm. On the one hand, it ensures that the alarm can only rise vertically along the direction of the through hole, avoiding swaying or deviation during the rise, and ensuring that the alarm can rise accurately to the designated position to issue an alarm signal.

[0021] On the other hand, the through hole is adapted to the upper end of the alarm, which limits the height of the alarm and prevents it from rising too high and causing damage. It also facilitates installation and maintenance, making the structure of the entire alarm mechanism more compact and reasonable.

[0022] As a further optimization of the present invention, a warning light is installed on the side of the upper end of the warning device away from the force block, and the number of warning lights is multiple and they are arranged at equal intervals in the longitudinal direction.

[0023] Multiple longitudinally equidistant warning lights provide workers with intuitive and clear warning information. As the force of the ship approaching the shore increases, the warning lights rise, and more warning lights gradually emerge from the exterior of the berthing pier and light up. Workers can intuitively judge the magnitude and range of the force of the ship approaching the shore by the number of warning lights that light up, and promptly understand the stress on the berthing pier so as to take corresponding measures, such as adjusting the ship's approaching speed or arranging personnel to check the condition of the berthing pier, thereby improving the safety and controllability of dock operations.

[0024] As a further optimization of the present invention, an alarm, a signal transmitter, and a controller are installed on the upper end of the pier body. A groove is provided on the side of the force block away from the pier body, and a pressure sensor flush with the contact surface of the force block is installed in the groove. The pressure sensor and the controller are electrically connected by a wire.

[0025] The pressure sensor monitors the pressure exerted on the load-bearing block by the ship when it docks in real time and converts the pressure signal into an electrical signal and transmits it to the controller. The controller is preset with a pressure threshold. When the detected pressure signal value exceeds the threshold, it controls the alarm to sound an alarm to attract the attention of on-site personnel. At the same time, it transmits the alarm information remotely to relevant personnel, such as dock management personnel or technicians, through the signal transmitter.

[0026] This multi-alarm system combines on-site warnings and remote notifications to ensure that relevant personnel can promptly obtain information on abnormal stress on the berths under any circumstances, take timely countermeasures, prevent damage to the berths due to excessive stress, and ensure the safety and normal operation of the dock facilities.

[0027] As a further optimized solution of the present invention, the buffer assembly includes a connecting column and a return spring disposed between the berthing block body and the force-bearing block. One end of the connecting column is fixed to the force-bearing block, and the other end of the connecting column is slidably sleeved with a sleeve hole opened on the berthing block body. The return spring is sleeved on the connecting column and its two ends are respectively fixed to the berthing block body and the force-bearing block.

[0028] When a ship docks, the buffer assembly plays a crucial role in buffering and resetting. The sliding sleeve structure of the connecting column and the sleeve hole guides the movement of the force-bearing block, ensuring that it can only approach or move away from the berthing pier body along the direction of the connecting column. The return spring, sleeved on the connecting column, is compressed under the force of the ship docking, absorbing and buffering the impact force of the ship on the berthing pier body, reducing the instantaneous force on the berthing pier body, and protecting the structural safety of the berthing pier. When the force of the ship docking disappears, the elasticity of the return spring returns the force-bearing block, fixed block, connecting frame, and sliding plate to their initial positions, preparing for the next ship docking alarm, ensuring the repeatability of the alarm mechanism, and extending the service life of the equipment.

[0029] A method for implementing a ship berthing force alarm mechanism includes the following specific steps:

[0030] S1: When the ship docks and comes into contact with the force block, the ship's force acts on the force block, and the force block slides towards the dock body under the push of the force, which shortens the distance between the dock body and the force block.

[0031] S2: During the sliding process of the force block, the fixed block moves synchronously with the force block. The fixed block drives the slide plate to slide in the slide groove through the connecting frame, so that the two slide plates drive the driving block on them to gradually approach each other. Since the two waists of the lower end of the movable block of the warning device are respectively in contact with the adjacent T-shaped groove, and the T-shaped block slides in cooperation with the T-shaped groove, the horizontal movement of the slide plate is converted into the driving force that drives the movable block and the warning device to move upward.

[0032] In this step, the force of the ship docking is transmitted to the sliding plate through the fixed block and connecting frame, realizing the transmission of force and the conversion of motion. The horizontal sliding of the sliding plate is transformed into the vertical upward motion of the moving block and the alarm by the special structure of the drive block and the moving block. This linkage design of the mechanical structure is ingenious, ensuring that the force of the ship docking can be accurately converted into the upward power of the alarm, so that the alarm mechanism can work stably and reliably.

[0033] S3: The upper end of the warning device slides upward along the through hole and extends to the outside of the berth body. As the warning device moves upward, multiple warning lights on it will gradually move to the outside of the berth body and light up, visually and accurately indicating the specific value of the force exerted when the ship docks, so as to remind on-site personnel to pay attention to the force situation of the berth body. The warning function is mainly achieved through the linkage of mechanical structure, which reduces the reliance on complex electronic components, reduces the probability of failure, and improves the stability and reliability of the equipment.

[0034] The alarm rises and activates the warning lights, providing on-site staff with a direct visual warning. By observing the number of lit warning lights, staff can roughly determine the magnitude of the force exerted by the ship approaching the shore and promptly understand the stress on the berthing pier. The warning function is mainly achieved through mechanical linkage. Compared to systems that rely on a large number of complex electronic components, this reduces the possibility of electronic component failures, such as short circuits and signal interference, thereby lowering the overall failure probability of the alarm mechanism, improving the stability and reliability of equipment operation, and ensuring the safety of dock operations.

[0035] S4: When the ship docks, the pressure sensor detects the pressure generated by the ship docking in real time and converts the pressure signal into an electrical signal output. This electrical signal is transmitted to the controller through a wire. The controller has a pressure threshold set in advance. When the received signal value exceeds the threshold, the controller controls the alarm to sound an alarm and can remotely transmit the alarm information to relevant personnel through a signal transmitter.

[0036] The pressure sensor monitors the pressure in real time and transmits the signal to the controller. The controller determines whether to issue an alarm based on a preset threshold. Once the pressure exceeds the limit, the alarm sounds to alert on-site personnel. At the same time, the signal transmitter remotely notifies relevant staff. This multi-alarm method ensures that alarm information can be delivered to relevant personnel in a timely and accurate manner from different angles, avoiding safety hazards caused by the failure of a single alarm method. It improves the reliability and timeliness of the alarm, ensuring that relevant personnel can obtain abnormal force information of the berthing pier in a timely manner, and protecting the safety of the dock facilities.

[0037] S5: When the ship docks, the distance between the force-bearing block and the berthing pier body shortens, and the connecting column continues to slide into the sleeve hole. The length of the connecting column between the berthing pier body and the force-bearing block gradually shortens, causing the return spring to be compressed and deformed. When the force of the ship docking disappears, under the action of the return spring, the force-bearing block, the fixing block, the connecting frame and the sliding plate return to their initial positions, the warning device falls back to its reset position, the warning light goes out, and the alarm state is deactivated.

[0038] The return spring plays a crucial role in this process. When the ship docks, it absorbs the impact and is compressed, protecting the docking pier. When the force of docking disappears, the return spring releases its elasticity, causing all components to return to their initial positions. The alarm falls back, the warning light goes out, and the alarm is deactivated, preparing for the next ship docking alarm. This automatic reset function ensures that the alarm mechanism can be used continuously and repeatedly, improving the practicality and stability of the equipment and reducing manual intervention and maintenance costs.

[0039] The ship berthing force alarm mechanism proposed in this invention has the following beneficial effects:

[0040] (i) The side of the pier body is connected to the force-bearing block through a buffer component. The distance between the two is adjustable under the force of the ship. A transmission component is installed between the pier body and the force-bearing block to convert the force of the ship on the force-bearing block into the lifting driving force of the warning device. When the ship docks, the force-bearing block moves under the force, which drives the warning device to rise. The warning light on the warning device lights up, and the staff can intuitively know the force situation, discover potential dangers in time, and avoid damage to the pier due to excessive force.

[0041] (ii) By installing an alarm, signal transmitter, and controller on the upper part of the berthing pier, and installing a pressure sensor in the groove of the force block, the pressure sensor is electrically connected to the controller. When the ship docks, the pressure sensor detects the pressure and converts it into an electrical signal, which is then transmitted to the controller. When the signal value exceeds the threshold, the controller controls the alarm to sound an alarm. At the same time, the alarm information is transmitted remotely through the signal transmitter. This multi-alarm method, which combines mechanical structure linkage with electronic detection, improves the reliability and timeliness of the alarm, ensuring that relevant personnel can obtain information on abnormal force on the berthing pier in a timely manner and take countermeasures.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0051] In the field of dock facility technology, if the force exerted by a ship on the berthing pier when it berths is too large, it will threaten the safety of the berthing pier and the normal progress of ship berthing operations. The ship berthing force alarm mechanism and its implementation method of the present invention aim to solve this problem, and its specific implementation method is as follows:

[0052] like Figures 1-4 As shown, the alarm mechanism is mainly constructed around the berth body 1. The side of the berth body 1 is connected to the force block 2 through a buffer assembly. The buffer assembly includes a connecting column 13 and a return spring 14. One end of the connecting column 13 is fixed to the force block 2, and the other end is slidably connected to the sleeve hole 20 on the berth body 1. The return spring 14 is sleeved on the connecting column 13, and both ends are fixed to the berth body 1 and the force block 2 respectively.

[0053] This connection method allows the distance between the berthing block body 1 and the force-bearing block 2 to be flexibly adjusted under the force of the ship. When the ship docks, the return spring 14 acts as a buffer to reduce the impact force on the berthing block body 1 and protect the structural safety of the berthing block.

[0054] like Figure 2 As shown, a groove 9 is provided on the side of the pier body 1 near the force block 2. A warning device 5 is installed in the groove 9. The warning device can slide and extend upward along the groove towards the pier body 1. A transmission assembly is installed between the pier body 1 and the force block 2. The transmission assembly consists of transmission units symmetrically distributed on both sides of the warning device 5. Each transmission unit includes a sliding plate 10, a fixing block 11 and a connecting frame 12. The fixing block 11 is fixed on the opposite surface of the force block 2 and the pier body 1. The two ends of the connecting frame 12 are rotatably connected to the sliding plate 10 and the fixing block 11, respectively. The sliding plate 10 slides in the groove 9 and is in transmission cooperation with the lower end of the warning device 5.

[0055] When the ship docks and applies force to the force-bearing block 2, the force-bearing block 2 slides towards the docking pier body 1. At this time, the fixing block 11 moves synchronously with the force-bearing block 2. The movement of the fixing block 11 drives the connecting frame 12 to move. Since the two connecting frames 12 are symmetrically distributed in a figure-eight shape, and the upper opening of the figure-eight shape faces the slide groove 9 and the lower opening faces the force-bearing block 2, this structure allows the connecting frame 12 to push the sliding plate 10 to slide in the slide groove 9 at a reasonable angle when the force-bearing block 2 moves, so that the two sliding plates 10 move closer to each other, thereby pushing the lower end of the warning device 5 upward.

[0056] Furthermore, such as Figure 5 As shown, a drive block 16 is installed at the upper end of the slide plate 10, and a movable block 15 is installed at the lower end of the warning device 5. The movable block 15 is an isosceles trapezoidal block that is wider at the top and narrower at the bottom. T-shaped blocks 17 are installed at the top of both sides of the block. A T-shaped groove 18 that matches the T-shaped block 17 is provided on the inclined surface of the drive block 16. The movable block 15 and the drive block 16 are slidably assembled through the T-shaped block 17 and the T-shaped groove 18, and the inclined surfaces of the two blocks that are close to each other are parallel.

[0057] During the sliding of the skateboard 10, the drive block 16 moves accordingly. Its horizontal movement generates an upward component force along the inclined surface of the movable block 15, thereby pushing the movable block 15 and the warning device 5 upward. In this way, the horizontal force of the ship on the force block 2 is cleverly converted into the lifting and lowering driving force of the warning device 5.

[0058] like Figure 2 As shown, the upper end of the berthing block body 1 is provided with a through hole 21 that is connected to the slide groove 9 and adapted to the upper end of the warning device 5. Under the drive of the transmission component, the upper end of the warning device 5 slides upward along the through hole 21 towards the upper part of the berthing block body 1. During the upward movement of the warning device 5, multiple longitudinally equidistant warning lights 19 installed on the side away from the force block 2 at its upper end will gradually move to the outside of the berthing block body 1 and light up. The staff can intuitively judge the magnitude and range of the force exerted by the ship berthing by the number of warning lights 19 that light up, so as to understand the force situation of the berthing block body 1 in a timely manner.

[0059] At the same time, such as Figure 1 As shown, an alarm 6, a signal transmitter 7 and a controller 8 are also installed on the upper end of the pier body 1. A groove 3 is provided on the side of the force block 2 away from the pier body 1. A pressure sensor 4 that is flush with the contact surface of the force block is installed in the groove 3. The pressure sensor 4 is electrically connected to the controller 8 through a wire.

[0060] When a ship docks, pressure sensor 4 detects the pressure generated by the ship docking in real time and converts the pressure signal into an electrical signal, which is then output to controller 8. Controller 8 is preset with a pressure threshold. When the received signal value exceeds the threshold, it controls alarm 6 to sound an alarm to attract the attention of on-site personnel. At the same time, it remotely transmits the alarm information to relevant personnel through signal transmitter 7, ensuring that relevant personnel can obtain information on abnormal force on the docking pier in a timely manner and take appropriate measures.

[0061] During the ship's docking process, the distance between the force-bearing block 2 and the docking pier body 1 shortens, and the connecting column 13 continuously slides into the sleeve hole 20 opened on the docking pier body 1. The return spring 14 is compressed and deformed. When the force of the ship docking disappears, the return spring 14 releases its elasticity, pushing the force-bearing block 2, the fixing block 11, the connecting frame 12, and the sliding plate 10 back to their initial positions. At the same time, the warning device 5 falls back to its initial position under its own weight and the indirect action of the return spring 14, the warning light 19 goes out, the alarm state is released, and the entire alarm mechanism returns to its initial state, preparing for the next ship docking alarm and ensuring that the alarm mechanism can be used continuously and repeatedly.

[0062] A method for implementing a ship berthing force alarm mechanism includes the following specific steps:

[0063] When the ship docks and comes into contact with the force block 2, the ship's force acts on the force block 2. Under the push of the force, the force block 2 slides towards the docking pier body 1, which shortens the distance between the docking pier body 1 and the force block 2.

[0064] During the sliding of the force-bearing block 2, the fixed block 11 moves synchronously with the force-bearing block 2. The fixed block 11 drives the slide plate 10 to slide in the slide groove 9 through the connecting frame 12. During the sliding of the slide plate 10, the driving block 16 moves accordingly. Its horizontal movement generates an upward component force along the inclined surface of the movable block 15, thereby pushing the movable block 15 and the warning device 5 to move upward.

[0065] The upper end of the S3 warning device 5 slides upward along the through hole 21 and extends to the outside of the berth body 1. As the warning device 5 moves upward, multiple warning lights 19 on it will gradually move to the outside of the berth body 1 and light up to remind on-site personnel to pay attention to the stress on the berth body 1.

[0066] When the ship docks, pressure sensor 4 detects the pressure generated by the ship docking in real time and converts the pressure signal into an electrical signal output. The electrical signal is transmitted to controller 8 through wires. Controller 8 is preset with a pressure threshold. When the received signal value exceeds the threshold, controller 8 controls alarm 6 to sound an alarm and can remotely transmit the alarm information to relevant personnel through signal transmitter 7.

[0067] When the ship docks, the distance between the force-bearing block 2 and the berthing pier body 1 shortens, and the connecting column 13 slides continuously into the sleeve hole 20. The length of the connecting column 13 between the berthing pier body 1 and the force-bearing block 2 gradually shortens, causing the return spring 14 to be compressed and deformed. When the force of the ship docking disappears, under the action of the return spring 14, the force-bearing block 2, the fixing block 11, the connecting frame 12 and the sliding plate 10 return to their initial positions, the warning device 5 falls back to reset, the warning light 19 goes out, and the alarm state is released.

[0068] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

Warning lights (19) are installed on the side of the upper end of the warning device (5) away from the force block (2). There are multiple warning lights (19) arranged longitudinally at equal intervals.

2. The ship berthing force alarm mechanism according to claim 1, characterized in that, Two connecting frames (12) are symmetrically distributed to form a figure-eight shape, with the upper opening of the figure-eight shape facing the slide groove (9) and the lower opening facing the force block (2).

3. The ship berthing force alarm mechanism according to claim 1, characterized in that, The upper end of the pier body (1) is provided with a through hole (21) that is connected to the slide groove (9) and adapted to the upper end of the warning device (5). Under the driving action of the transmission component, the upper end of the warning device (5) slides along the through hole (21) towards the upper part of the pier body (1).

4. The ship berthing force alarm mechanism according to claim 3, characterized in that, An alarm (6), a signal transmitter (7), and a controller (8) are installed on the upper end of the pier body (1). A groove (3) is provided on the side of the force block (2) away from the pier body (1), and a pressure sensor (4) is installed in the groove (3). The pressure sensor (4) and the controller (8) are electrically connected by a wire.

5. The ship berthing force alarm mechanism according to claim 4, characterized in that, The buffer assembly includes a connecting column (13) and a return spring (14) disposed between the berthing block body (1) and the force-bearing block (2). One end of the connecting column (13) is fixed to the force-bearing block (2), and the other end of the connecting column (13) is slidably connected to the sleeve hole (20) opened on the berthing block body (1). The return spring (14) is sleeved on the connecting column (13) and its two ends are fixed to the berthing block body (1) and the force-bearing block (2) respectively.

6. A method for implementing the ship berthing force alarm mechanism as described in claim 5, characterized in that, The specific steps are as follows: S1: When the ship docks and comes into contact with the force block (2), the ship's force acts on the force block (2), and the force block (2) slides towards the docking pier body (1) under the push of the force, which shortens the distance between the docking pier body (1) and the force block (2). S2: During the sliding process of the force block (2), the fixed block (11) moves synchronously with the force block (2). The fixed block (11) drives the slide plate (10) to slide in the slide groove (9) through the connecting frame (12), so that the two slide plates (10) drive the driving block (16) on them to gradually approach each other. Since the two waists of the lower end of the movable block (15) of the warning device (5) are respectively in contact with the adjacent T-shaped groove (18), and the T-shaped block (17) slides with the T-shaped groove (18), the horizontal movement of the slide plate (10) is converted into the driving force that drives the movable block (15) and the warning device (5) to move upward. S3: The upper end of the warning device (5) slides upward along the through hole (21) and extends to the outside of the pier body (1). During the upward movement of the warning device (5), multiple warning lights (19) on it will gradually move to the outside of the pier body (1) and light up to remind the on-site staff to pay attention to the stress on the pier body (1). S4: When the ship docks, the pressure sensor (4) detects the pressure generated by the ship docking in real time and converts the pressure signal into an electrical signal output. The electrical signal is transmitted to the controller (8) through the wire. The controller (8) has a pressure threshold preset. When the received signal value exceeds the pressure threshold, the controller (8) controls the alarm (6) to sound an alarm and transmits the alarm information remotely to the relevant personnel through the signal transmitter (7). S5: When the ship docks, the distance between the force block (2) and the berthing pier body (1) is shortened, the connecting column (13) slides continuously into the sleeve hole (20), and the length of the connecting column (13) between the berthing pier body (1) and the force block (2) is gradually shortened, so that the return spring (14) is compressed and deformed. When the force of the ship docking disappears, under the action of the return spring (14), the force block (2), the fixing block (11), the connecting frame (12) and the sliding plate (10) return to their initial positions, the warning device (5) falls down to reset, the warning light (19) goes out, and the alarm state is released.
