Description

Technical Field

[0001] The present invention relates to the field of ships, and particularly to a ship anchor chain tension adaptive anchoring device. Background Art

[0002] Traditional anchor chain tension adjustment mainly relies on manual adjustment, making it difficult to achieve precise response to dynamic changes in the marine environment. Existing technologies usually lack the ability to monitor and automatically adjust the anchor chain tension in real time. As a result, when encountering different sea conditions, such as strong winds and large waves, the anchor chain may become too loose or too tight, not only affecting the stability and safety of the ship, but also possibly causing excessive wear or even damage to the anchor chain and anchoring equipment.

[0003] Currently, a disclosed wildcat winch with retracting and adjusting function in China with the authorized announcement number of CN118560638B includes a base. Two fixing frames are fixedly connected to the top of the base. A motor is fixedly connected to one side of the top of the base. The output shaft of the motor is fixedly connected to a first rotating rod. The first rotating rod is spline-connected to a rotating frame. A slide plate is horizontally slidably connected to one side of the base close to the motor. The slide plate is rotatably connected to the rotating frame. A screw rod frame is rotatably connected to one side of the base close to the motor. The slide plate is vertically slidably connected with sliders symmetrically distributed along the screw rod frame. The sliders are provided with internal threads, and the internal threads of the sliders cooperate with the external threads of the screw rod frame. The slide plate is fixedly connected with first springs symmetrically distributed along the screw rod frame. The sliders are fixedly connected with the adjacent first springs. A second rotating rod is rotatably connected between the two fixing frames. The rotating frame is movably connected with the second rotating rod. A turntable is fixedly connected to the end of the second rotating rod close to the first rotating rod. The turntable is fixedly connected with anchor retracting adjusting balls symmetrically distributed along the turntable. Initially, the anchor retracting adjusting balls are in contact with the rotating frame. The turntable is fixedly connected with anchor releasing adjusting balls symmetrically distributed along the turntable. Initially, there is a gap for anchor retracting adjustment between the anchor releasing adjusting balls and the rotating frame. The anchor releasing adjusting balls and the anchor retracting adjusting balls are alternately and spacedly distributed. An anchor winch disc is fixedly connected to the second rotating rod. The base is provided with a limit and restoration assembly for limiting the sliders and making the sliders move to the initial position of the screw rod frame.

[0004] According to the above-mentioned patent, the patent does not require changing the motor speed. By simply rotating the screw frame forward or backward, the tension of the anchor chain or rope can be adjusted during the process of the windlass winding in or paying out the anchor chain or rope. In this way, potential safety hazards caused by excessive tension or relaxation of the anchor chain or rope are avoided, and the service life of the motor is extended. However, this method relies on the rotation of the screw frame to indirectly adjust the tension of the anchor chain, and may not be able to respond in real time to rapidly changing sea conditions. It is necessary to manually or control the rotation direction and speed of the screw frame through a preset program, with relatively poor flexibility and difficulty in automatically adapting to different marine environments. Therefore, there is a need for a ship anchor chain tension adaptive anchoring device that can monitor the tension of the anchor chain in real time and adjust it promptly. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, a ship anchor chain tension adaptive anchoring device is provided. Through the coordinated work and synchronous relative movement of the upper tension pulley and the lower tension pulley, dynamic and precise adjustment of the anchor chain tension is achieved, avoiding the imbalance problem caused by unilateral adjustment. When the monitoring component detects that the anchor chain is too loose or too tight, the positioning drive adjusts and locks the position of the movable frame, reducing unnecessary movement, and then quickly adjusts the positions of the upper tension pulley and the lower tension pulley to change the anchor chain tension, ensuring that it is maintained within the normal tension range.

[0006] To solve the problems of the prior art, the present invention provides a ship anchor chain tension adaptive anchoring device, including a fixed frame and a sprocket provided thereon for guiding the winding in and paying out of the anchor chain. A tension adjustment mechanism for dynamically adjusting the tension of the anchor chain is provided on the fixed frame. The tension adjustment mechanism includes a movable frame and an adjustment component provided on the movable frame. The movable frame can move on the fixed frame along a direction perpendicular to the lowering direction of the anchor chain. A monitoring component for judging the tension of the anchor chain by monitoring the movement state of the movable frame is also provided on the fixed frame. When the movable frame reciprocates on the fixed frame, the anchor chain is in a too loose state, and at the same time, the adjustment component tightens the anchor chain. When the movable frame moves to one end on the fixed frame, the anchor chain is in a too tight state, and at the same time, the adjustment component relaxes the anchor chain.

[0007] Preferably, the adjustment component includes an upper tension pulley and a lower tension pulley which are respectively arranged on one side of the anchor chain and are distributed vertically. Both the upper tension pulley and the lower tension pulley can move towards the anchor chain on the movable frame. When the upper tension pulley and the lower tension pulley approach or move away from each other, the anchor chain is in a tightened or relaxed state.

[0008] Preferably, both the upper tension pulley and the lower tension pulley are rubber wheels. When the upper tension pulley and the lower tension pulley are squeezed by the anchor chain without driving the movable frame to move, the anchor chain is in a normal tension state, and at this time, the anchor chain does not require tension adjustment.

[0009] Preferably, buffer layers are provided at both ends of the movable frame in the moving direction to prevent the movable frame from directly hitting the fixed frame.

[0010] Preferably, a positioning driver capable of stably centering the movable frame is provided on the fixed frame. When the upper and lower tensioning wheels need to adjust the overly slack anchor chain, the movable frame is in a stable state under the action of the positioning driver, enabling precise tension adjustment of the anchor chain.

[0011] Preferably, the positioning driver has compression rods symmetrically arranged at both ends of the movable frame and a force - applying plate capable of pressing on each compression rod. The force - applying plate can move on the fixed frame along a direction parallel to the movable frame. When the two force - applying plates approach each other, the movable frame is in a gradually stable state under the force - receiving state of the compression rods.

[0012] Preferably, sliding seats for rotatably connecting the upper and lower tensioning wheels are respectively provided on the movable frame. The movable frame has guide rods slidably connected to the fixed frame, and a tensioning driver for driving the two sliding seats to move synchronously and relatively is provided on the guide rods.

[0013] Preferably, the monitoring component includes tension sensors provided on the fixed frame and connected to both ends of the movable frame. The tension sensors have elastic draw ropes. When the anchor chain is too loose, the elastic draw ropes at both ends are in an alternating stretching and relaxing state, while when the anchor chain is too tight, one elastic draw rope is always in a stretched state and the other elastic draw rope is always in a relaxed state.

[0014] Preferably, compression springs connected to both ends of the movable frame are provided on the fixed frame. When all the compression springs are in a normal state, the movable frame is centered on the fixed frame, and at this time, the anchor chain is in a normal tension state.

[0015] Preferably, the tensioning driver has a winch rotatably arranged on the guide rod and a rigid draw rope connecting the winch and each sliding seat. A rope - winding rod is provided at the end of each sliding seat on the movable frame, and each rigid draw rope winds out from the outside of the corresponding rope - winding rod.

[0016] The beneficial effects of this application compared with the prior art are as follows: 1. Through the coordinated operation of the upper and lower tensioning wheels, the present invention realizes dynamic and precise adjustment of the tension of the anchor chain. When the monitoring component detects that the anchor chain is too loose or too tight, the upper and lower tensioning wheels quickly adjust their positions to change the tension of the anchor chain, ensuring that the anchor chain is maintained within an ideal range.

[0017] When the movable frame moves relative to the fixed frame due to the swaying of the anchor chain, the buffer layer on the movable frame effectively absorbs the impact energy, avoiding damage caused by the direct impact between the movable frame and the fixed frame. This enables the monitoring component to effectively and accurately monitor the tension of the anchor chain in real time, ensuring the safe mooring of the ship in various sea conditions.

[0018] 2. The present invention adjusts and locks the position of the movable frame through the positioning drive, ensuring the accuracy and stability during the tension adjustment of the anchor chain. When the monitoring component detects that the anchor chain is too loose or too tight, the control system sends an instruction to the positioning drive, causing the two force-applying plates to approach each other and apply pressure to the compression rod, guiding the movable frame to move towards the central position and firmly lock. This not only reduces the unnecessary movement of the movable frame but also provides a solid foundation for the upper tensioning wheel and the lower tensioning wheel, enabling them to perform the tensioning task more effectively.

[0019] Since the movable frame remains stationary during this process, the accuracy of the tensioning operation is guaranteed, avoiding adjustment errors caused by instability. The precise dynamic adjustment of the anchor chain tension is achieved, enhancing the reliability of the adaptive adjustment of the anchor chain.

[0020] 3. The present invention adjusts the position of the sliding seat through the tensioning drive, causing the upper tensioning wheel and the lower tensioning wheel to approach or separate from each other, thereby precisely controlling the tension of the anchor chain. The synchronous and relative movement of the upper tensioning wheel and the lower tensioning wheel avoids the uneven problem caused by unilateral adjustment.

[0021] In addition, the state changes of the elastic pull rope and the compression spring help to monitor the tension condition of the anchor chain in real time, ensuring that the movable frame is centered and stable in the normal state, indicating that the tension of the anchor chain is moderate and does not require adjustment. When the abnormal tension of the anchor chain is detected, the upper tensioning wheel and the lower tensioning wheel are quickly activated for adaptive adjustment to dynamically adjust the tension of the anchor chain.

Detailed implementation manners

[0033] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0034] See Figures 1 - 4 As shown, a self - adaptive anchoring device for ship anchor chains includes a fixed frame 1 and a sprocket 3 provided thereon for guiding the retraction and release of the anchor chain 2. A tension adjustment mechanism for dynamically adjusting the tension of the anchor chain 2 is provided on the fixed frame 1. The tension adjustment mechanism includes a movable frame 4 and an adjustment assembly 5 provided on the movable frame 4. The movable frame 4 can move on the fixed frame 1 along a direction perpendicular to the lowering direction of the anchor chain 2. A monitoring assembly 6 for judging the tension of the anchor chain 2 by monitoring the movement state of the movable frame 4 is also provided on the fixed frame 1. When the movable frame 4 reciprocates on the fixed frame 1, the anchor chain 2 is in an over - loose state, and at the same time, the adjustment assembly 5 tightens the anchor chain 2. When the movable frame 4 moves to one end on the fixed frame 1, the anchor chain 2 is in an over - tight state, and at the same time, the adjustment assembly 5 relaxes the anchor chain 2.

[0035] The fixed frame 1 and the movable frame 4 are respectively composed of multiple plate members which are detachably connected, facilitating maintenance.

[0036] On the one hand, when the ship encounters different sea conditions at sea, for example, when the wind and waves are large and the anchor chain 2 is too loose. During this process, the anchor chain 2 will continuously swing under the influence of the wind and waves. At this time, the anchor chain 2 drives the movable frame 4 to freely move on the fixed frame 1 along the direction perpendicular to the lowering direction of the anchor chain 2. During this process, the monitoring component 6 monitors the movement status of the movable frame 4 in real time, so as to respond to the change of the tension of the anchor chain 2 in real time.

[0037] Once the monitoring component 6 detects that the movable frame 4 starts to reciprocate, it indicates that the anchor chain 2 is in a too-loose state. At this time, the monitoring component 6 transmits a signal to the adjusting component 5 through the control system, and the adjusting component 5 immediately starts the action of tightening the anchor chain 2 to increase the tension of the anchor chain 2 and ensure that the ship will not drift due to the too-loose anchor chain 2.

[0038] On the other hand, when the sea area where the ship is located is relatively calm, the lowered ship anchor may cause the anchor chain 2 to be overly tightened due to improper adjustment. In this case, the movable frame 4 will be pulled towards one end of the fixed frame 1 by the anchor chain 2. The monitoring component 6 will also capture the movement change of the movable frame 4 and feedback the information to the adjusting component 5. After receiving the signal, the adjusting component 5 will automatically relax the anchor chain 2 to relieve the pressure on the anchor chain 2 and the connected equipment and prevent the risk of wear or fracture caused by over-tightening.

[0039] During the process of the movable frame 4 moving due to the movement of the anchor chain 2, the monitoring component 6 needs to monitor the position change of the movable frame 4 in real time, so as to accurately judge the current tension status of the anchor chain 2 and make a timely and accurate response through the adjusting component 5. Based on the data provided by the monitoring component 6, the adjusting component 5 can quickly make adjustments to ensure that the anchor chain 2 is always maintained within an ideal tension range. The tension of the anchor chain 2 can be dynamically adjusted according to actual needs, effectively ensuring the safety and stability of the ship whether in a harsh marine environment or relatively calm conditions.

[0040] See Figures 1 - 7 As shown, the adjusting component 5 includes an upper tensioning wheel 51 and a lower tensioning wheel 52 which are respectively arranged on one side of the anchor chain 2 and are distributed up and down. Both the upper tensioning wheel 51 and the lower tensioning wheel 52 can move towards the direction of the anchor chain 2 on the movable frame 4. When the upper tensioning wheel 51 and the lower tensioning wheel 52 approach or move away from each other, the anchor chain 2 is in a tightened or relaxed state.

[0041] When the monitoring component 6 detects that the movable frame 4 starts to reciprocate, it indicates that the anchor chain 2 is in a too loose state. At this time, the upper tensioning wheel 51 and the lower tensioning wheel 52 in the adjusting component 5 will approach each other according to the received signal, thereby tightening the anchor chain 2. As the two wheels approach, the pressure they exert on the anchor chain 2 increases, causing the anchor chain 2 to be tightened and increasing its tension.

[0042] On the contrary, when the sea surface is relatively calm, it may cause the anchor chain 2 to be overly tightened. At this time, the movable frame 4 will be pulled by the anchor chain 2 towards one end of the fixed frame 1. The monitoring component 6 recognizes this change and instructs the adjusting component 5 to loosen the anchor chain 2. At this time, the upper tensioning wheel 51 and the lower tensioning wheel 52 will move away from each other, reducing the pressure exerted on the anchor chain 2, enabling the anchor chain 2 to be relaxed and reducing the pressure on the anchor chain 2 and the connected equipment.

[0043] See Figures 2 - 7 As shown, both the upper tensioning wheel 51 and the lower tensioning wheel 52 are rubber wheels. When the upper tensioning wheel 51 and the lower tensioning wheel 52 are squeezed by the anchor chain 2 without driving the movable frame 4 to move, the anchor chain 2 is in a normal tension state, and at this time, the anchor chain 2 does not require tension adjustment.

[0044] When the anchor chain 2 passes between the upper tensioning wheel 51 and the lower tensioning wheel 52, if the tension of the anchor chain 2 is moderate, then the rubber wheels will be subjected to pressure from the anchor chain 2 and closely adhere to the surface of the anchor chain 2. Due to the elastic and deformable properties of the rubber material, the rubber wheels can automatically adjust the contact area and pressure distribution according to the actual shape and tension of the anchor chain 2.

[0045] In the state where the anchor chain 2 squeezes the upper tensioning wheel 51 and the lower tensioning wheel 52, although the upper tensioning wheel 51 and the lower tensioning wheel 52 bear the pressure brought by the anchor chain 2, because the tension of the anchor chain 2 is within the normal range, the upper tensioning wheel 51 and the lower tensioning wheel 52 will not cause the position change of the movable frame 4. That is, although there is a certain pressure acting on the rubber wheels, since the pressure is within the expected range, it will not cause the movable frame 4 to displace relative to the fixed frame 1. Therefore, the monitoring component 6 will not detect the movement status information of the movable frame 4, and the entire movable frame 4 remains in a stable state, that is, the anchor chain 2 is in a normal tension state.

[0046] When the pressure of the anchor chain 2 on the upper tensioning wheel 51 and the lower tensioning wheel 52 exceeds the expected range, the movable frame 4 is driven to move on the fixed frame 1. At this time, the movement status of the movable frame 4 is detected by the monitoring component 6, and at this time, it is necessary to adjust the tension of the anchor chain 2 through the upper tensioning wheel 51 and the lower tensioning wheel 52.

[0047] In addition, compared with hard materials, the softness of rubber can effectively reduce the direct friction between the anchor chain 2 and the upper tensioning wheel 51 and the lower tensioning wheel 52, thereby reducing the wear degree between the two. This means that even after long-term use, the anchor chain 2, the upper tensioning wheel 51, and the lower tensioning wheel 52 can maintain a good working state, extending their service life and reducing maintenance costs.

[0048] See Figures 2 - 4 and Figures 6 - 8 As shown, buffer layers 41 for preventing the movable frame 4 from directly hitting the fixed frame 1 are respectively provided at both ends of the movable frame 4 in the moving direction.

[0049] When the movable frame 4 moves along the fixed frame 1 due to changes in the tension of the anchor chain 2, it may quickly approach both ends of the fixed frame 1 due to excessive external force or inertia. Without the presence of the buffer layer 41, the direct impact may cause deformation or even damage to the movable frame 4 and the fixed frame 1, thereby affecting the normal operation of the monitoring component 6.

[0050] The buffer layer 41 has high elasticity and energy absorption characteristics and can absorb and disperse the energy generated by the impact. When the movable frame 4 moves to a position close to the limit position of the fixed frame 1, the buffer layer 41 first contacts the fixed frame 1 and slows down the impact force through its own deformation. This not only effectively reduces the risk of damage caused by the impact but also reduces noise and vibration, improving the stability and durability of the movable frame 4.

[0051] See Figures 1 - 4 and Figure 10 As shown, a positioning driver 11 capable of centering the movable frame 4 stably is provided on the fixed frame 1. When the upper tensioning wheel 51 and the lower tensioning wheel need to adjust the overly loose anchor chain 2, the movable frame 4 is in a stable state under the action of the positioning driver 11, enabling precise tension adjustment of the anchor chain 2.

[0052] When the monitoring component 6 detects that the anchor chain 2 is too loose, it indicates that the anchor chain 2 needs to be tightened by the upper tensioning wheel 51 and the lower tensioning wheel 52 at this time. To ensure the accuracy of the adjustment, it is first necessary to ensure that the movable frame 4 is in a stable state. At this time, the positioning driver 11 adjusts and locks the position of the movable frame 4 to ensure that the movable frame 4 can accurately stay at the required position.

[0053] Once it is determined that the tension adjustment of the anchor chain 2 is required, the monitoring component 6 will first send a signal to the positioning driver 11 through the control system. After receiving the instruction, the positioning driver 11 starts to work to stabilize the movable frame 4. It pushes the movable frame 4 to the central position by applying appropriate force. The stable positioning not only helps to reduce any unnecessary movement of the movable frame 4 during the adjustment process but also provides a solid foundation for the upper tensioning wheel 51 and the lower tensioning wheel 52, enabling them to perform the tensioning task more effectively.

[0054] After the movable frame 4 is accurately positioned and stabilized, the upper tensioning wheel 51 and the lower tensioning wheel 52 can perform precise tensioning adjustment on the slack anchor chain 2 according to the data provided by the monitoring component 6. Since the movable frame 4 remains stationary during this process, the accuracy of the tensioning operation is ensured, and the adjustment error caused by the instability of the movable frame 4 is avoided.

[0055] See Figures 1 - 4 and Figure 10 As shown, the positioning driver 11 has pressure rods 111 symmetrically arranged at both ends of the movable frame 4 and force-applying plates 112 capable of applying pressure to each pressure rod 111. The force-applying plates 112 can move on the fixed frame 1 along a direction parallel to the movable frame 4. When the two force-applying plates 112 approach each other, the movable frame 4 is in a gradually stabilized state under the force-bearing state of the pressure rods 111.

[0056] The drive source for driving the movement of the force-applying plates 112 is not shown in the figure.

[0057] When the monitoring component 6 detects that the anchor chain 2 is too loose, the control system sends an instruction to the positioning driver 11. Then, the positioning driver 11 is activated, causing the two force-applying plates 112 to start approaching each other. As the force-applying plates 112 gradually approach, pressure is applied to their respective pressure rods 111. Since the pressure rods 111 are directly connected to the movable frame 4, the applied pressure causes the movable frame 4 to feel balanced forces from both sides, thereby guiding it to move towards the center position of the fixed frame 1.

[0058] During this process, as the two force-applying plates 112 continue to move inward and apply pressure to the pressure rods 111, the movable frame 4 gradually enters a stabilized state, making it less likely to move unnecessarily due to external factors. At this time, the movable frame 4 is in a stable locked state, ensuring that there is no displacement during the tensioning operation of the anchor chain 2.

[0059] See Figures 1 - 4 、 Figure 9 and Figure 10 As shown, sliding seats 42 for the upper tensioning wheel 51 and the lower tensioning wheel 52 to be rotatably connected thereto are respectively provided on the movable frame 4. The movable frame 4 has a guide rod 43 slidably connected to the fixed frame 1, and a tensioning driver 44 for driving the two sliding seats 42 to move synchronously and relatively is provided on the guide rod 43.

[0060] When the monitoring component 6 detects that the anchor chain 2 is too loose, the control system will send an instruction to the tensioning drive 44. Then, the tensioning drive 44 prompts the two sliding seats 42 to move inward simultaneously, driving the upper tensioning wheel 51 and the lower tensioning wheel 52 closer to each other, increasing the pressure on the anchor chain 2, and thus tightening the anchor chain 2. On the contrary, if it is detected that the anchor chain 2 is too tight, the tensioning drive 44 will drive the two sliding seats 42 to move outward, separating the upper tensioning wheel 51 and the lower tensioning wheel 52, reducing the pressure on the anchor chain 2, and achieving the purpose of relaxing the anchor chain 2.

[0061] The synchronous and relative movement function of the tensioning drive 44 enables the tension adjustment of the anchor chain 2 to be both precise and efficient, avoiding the imbalance problem caused by unilateral adjustment. Dynamically adjusting the tension of the anchor chain 2 ensures the safe mooring of the ship.

[0062] See Figures 1 - 4 and Figures 6 - 8 As shown in, the monitoring component 6 includes a tension sensor disposed on the fixed frame 1 and connected to both ends of the movable frame 4. The tension sensor has an elastic drawstring 61. When the anchor chain 2 is too loose, the two ends of the elastic drawstring 61 are in an alternating stretching and relaxing state. When the anchor chain 2 is too tight, one end of the elastic drawstring 61 is always in a stretched state, while the other end of the elastic drawstring 61 is always in a relaxed state.

[0063] The detection part of the tension sensor that specifically detects the elastic drawstring 61 is not shown in the figure.

[0064] When the anchor chain 2 is too loose, due to the influence of factors such as sea waves or wind, the movable frame 4 will move with the swaying of the anchor chain 2. In this case, with the reciprocating movement of the movable frame 4, one end of the elastic drawstring 61 is stretched while the other end is in a relaxed state. The alternating stretching and relaxing mode indicates that the anchor chain 2 is currently too loose and needs to be adjusted to increase its tension.

[0065] On the contrary, when the anchor chain 2 is too tight, the overly tightened anchor chain 2 causes the movable frame 4 to tilt to one side and stay there, rather than moving back and forth as in the too-loose state. In this situation, the continuously stretched elastic drawstring 61 on one side shows that the anchor chain 2 is under too much tension and some tension needs to be released to prevent damage to the equipment.

[0066] See Figures 2 - 4 and Figures 6 - 8 As shown in, compression springs 62 are provided on the fixed frame 1 and connected to both ends of the movable frame 4. When all the compression springs 62 are in a normal state, the movable frame 4 is centered on the fixed frame 1, and at this time, the anchor chain 2 is in a normal tension state.

[0067] When all the compression springs 62 are in a normal state, the compression springs 62 are neither over-compressed nor over-stretched, but remain in the normal state. At this time, the movable frame 4 will be centered on the fixed frame 1, and the movable frame 4 will not be subjected to additional pressure or tension from any direction and will stably maintain its position at the center, indicating that the tension on the anchor chain 2 at present is moderate and does not require adjustment.

[0068] Refer to Figure 1 、 Figure 9 and Figure 10 As shown, the tensioning drive 44 has a winch 441 rotatably arranged on the guide rod 43 and a rigid draw rope 442 connecting the winch 441 and each sliding seat 42. On the movable frame 4, a rope winding rod 4421 is provided at the end of the movement of each sliding seat 42, and each rigid draw rope 442 respectively winds out from the outside of the corresponding rope winding rod 4421.

[0069] The drive source for driving the winch 441 to rotate is not shown in the figure.

[0070] When it is monitored that the anchor chain 2 is too loose or too tight, at this time the winch 441 starts to rotate, and the rigid draw rope 442 is taken in or released according to the information of the monitoring component 6. If it is necessary to tighten the anchor chain 2, the winch 441 will tighten the rigid draw rope 442, causing the two sliding seats 42 to approach each other. At this time, the upper tensioning wheel 51 and the lower tensioning wheel 52 squeeze the anchor chain 2 into a compressed state. On the contrary, if it is necessary to loosen the anchor chain 2, under the elastic action of the upper tensioning wheel 51 and the lower tensioning wheel 52, it will automatically return to the normal state, forcing the two sliding seats 42 to separate.

[0071] During the process of the rigid draw rope 442 being pulled, since the rigid draw rope 442 winds out from the outside of the rope winding rod 4421, it is ensured that the rigid draw rope 442 can smoothly guide the movement of the sliding seat 42. To ensure that even when the sliding seat 42 reaches the movement limit position, the rigid draw rope 442 can maintain the correct angle and tension, avoiding jamming or slipping.

[0072] Through the coordinated work and synchronous relative movement of the upper tensioning wheel 51 and the lower tensioning wheel 52, the present invention realizes the dynamic and precise adjustment of the tension of the anchor chain 2, avoiding the unbalanced problem caused by unilateral adjustment. When the monitoring component 6 detects that the anchor chain 2 is too loose or too tight, it quickly adjusts the positions of the upper tensioning wheel 51 and the lower tensioning wheel 52 to change the tension of the anchor chain 2 and ensure that it is maintained within the normal tension range.

[0073] Before adjusting the slack anchor chain 2, the positioning driver 11 adjusts and locks the position of the movable frame 4, reducing unnecessary movement, providing a solid foundation for the tensioning task, and ensuring operation accuracy. At the same time, the state changes of the elastic pull rope 61 and the compression spring 62 monitor the tension of the anchor chain 2 in real time, ensuring that the movable frame 4 is centered and stable, and reflecting that the tension of the anchor chain 2 is moderate and does not require adjustment. This enhances the response speed, precision, and reliability of tension adjustment, guaranteeing the safe mooring of the ship in various sea conditions.

[0074] The above embodiments only represent one or several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
