[0003] The cable tensioner is usually composed of a cable, a cable tensioning device, a cable adjuster, etc. These devices can ensure that the ship is always in a stable mooring state when moored. The design of the tensioner allows the tension of the cable to be adjusted through the tensioning device, ensuring that the tension of the cable is always in a suitable state and will not be deformed or broken due to external forces.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0030] See also Figure 1 to Figure 10In an embodiment of the present invention, an active compensating ship cable tensioner based on ship motion monitoring includes: a support frame 1, a trigger release component and an elastic support mechanism.

[0031] A tensioning assembly is provided on the support frame 1, on which a traction cable 5 is wound, and the traction cable 5 is formed with a first return portion and a second return portion on the tensioning assembly, and the tensioning assembly can adjust the position of the first return portion relative to the second return portion; the tensioning assembly includes a guide frame 2 and a first winding roller 3 provided on the support frame 1, and the guide frame 2 is provided with a second inclined slide groove 201, and the rotating shaft of the first winding roller 3 can slide in the second inclined slide groove 201; the tensioning assembly also includes a hydraulic cylinder 6 and a second winding roller 4 provided on the support frame 1, and the action end of the hydraulic cylinder 6 is connected to the rotating shaft of the first winding roller 3 through the trigger release assembly. When the hydraulic cylinder 6 is actuated, the first winding roller 3 can be driven to move along the length direction of the second inclined slide groove 201, so that the first return portion moves away from the second return portion; a ship motion monitoring module establishes communication with the tensioning assembly, and is used to judge the tension change value of the traction cable 5 according to tidal data and wind data, so as to control the action of the tensioning assembly.

[0032] When in use, the traction cable 5 is wound in a manner of bending upward from the lower part of the second winding roller 4, then bending downward from the upper part of the first winding roller 3 and winding out from the lower part of the second winding roller 4 again, wherein the traction cable 5 forms a first return portion on the first winding roller 3 and a second return portion on the second winding roller 4, and when the length of the traction cable 5 is constant, when the hydraulic cylinder 6 is actuated to push the first winding roller 3 away from the second winding roller 4, the distance wound between the first winding roller 3 and the second winding roller 4 will increase, thereby reducing the length of the traction cable 5 reserved outside the first winding roller 3 and the second winding roller 4, and at this time, the ship can be pulled, on the contrary, when the hydraulic cylinder 6 drives the first winding roller 3 to move toward the second winding roller 4, the length of the traction cable 5 reserved outside the first winding roller 3 and the second winding roller 4 will increase, and the ship can be released, and by pulling and releasing the ship, a more stable effect of the ship can be achieved.

[0033] It should be noted that the weather monitoring system can be used to monitor tidal data and wind data for a period of time in the future to simulate the movement of the ship and calculate the ship's distance from the shore under the action of wind and tide. The control system can then control the action of the hydraulic cylinder 6 to increase the elongation of the traction cable 5, thereby eliminating the possibility of breakage of the traction cable 5 to a certain extent.

[0034] At the same time, the control system is also provided with a traction cable 5 tension detector. When the tension of the traction cable 5 is close to the maximum preset value (traction cable 5 tension data), the hydraulic cylinder 6 moves under the action of the control system; the automatic control of the tensioner is achieved through the coordinated cooperation of the set ship motion monitoring and the tension detector.

[0035] The above-mentioned tidal data and wind data are imported into the ship motion state simulator to calculate the ship's attitude and offshore distance within a preset time.

[0036] See also Figure 8~Figure 9 , the trigger release assembly is connected to the tensioning assembly, the trigger release assembly can lock the position of the first return part, and when the tensioning assembly is actuated, the trigger release assembly can release the position lock of the first return part; the trigger release assembly includes a driving member 19 fixedly connected to the action end of the hydraulic cylinder 6, a through groove for displacement of the first winding roller 3 is formed in the driving member 19, and an extrusion structure is slidably mounted on the driving member 19, and the extrusion structure cooperates with the locking plate 26 arranged on the guide frame 2; the trigger release assembly also includes a rotating shaft arranged on the driving member 19 and connected to the first winding roller 3 An adaptive stop structure, which can make the rotating shaft of the first winding roller 3 abut against the extrusion structure, wherein the stop structure includes a stop member 28 that is slidably connected to the driving member 19, the sliding direction of the stop member 28 is perpendicular to the through groove, and the stop member 28 is provided with a guide portion 2801 for driving the rotating shaft of the first winding roller 3 to move; the stop structure also includes an electric telescopic rod 27 rotatably mounted on the hydraulic cylinder 6, and the end of the electric telescopic rod 27 away from the hydraulic cylinder 6 is rotatably connected to the stop member 28, and specifically, the electric telescopic rod 27 is connected to the action end of the hydraulic cylinder 6.

[0037] In the initial state, the guide portion 2801 is in contact with the rotating shaft of the first winding roller 3. At this time, the rotating shaft of the first winding roller 3 is in the middle position of the through groove and does not interact with the extrusion structure. At the same time, under the self-locking action of the extrusion structure, the driving member 19 can be locked, and in this state, the first winding roller 3 can be in a locked state, so that in the above state, the hydraulic cylinder 6 does not need to support the rotating shaft of the first winding roller 3, thereby preventing the hydraulic cylinder 6 from being in a high oil pressure state for a long time, causing hydraulic oil leakage, and improving the durability of the hydraulic cylinder 6.

[0038] When the position of the first winding roller 3 needs to be adjusted, the electric telescopic rod 27 is controlled to move so that the stopper 28 can move upward in a length direction perpendicular to the through slot. At this time, since the first winding roller 3 is always subjected to a downward force, when there is no support from the guide portion 2801, the first winding roller 3 can move toward the lower end of the through slot, thereby abutting against the extrusion structure and triggering the extrusion structure to move. At this time, the extrusion structure is unlocked, and the first winding roller 3 can follow the movement of the hydraulic cylinder 6 to achieve the adjustment of the tension of the traction cable 5.

[0039] It should be noted that since the movement direction of the stopper 28 is perpendicular to the length direction of the through groove, when the first winding roller 3 is subjected to force and acts in the reverse direction on the stopper 28, the stopper 28 will only generate a force in one direction acting on the rotating shaft of the first winding roller 3, that is, there is no component force in other directions, so that when the rotating shaft of the first winding roller 3 is in contact with the stopper 28, the stopper 28 can be subjected to balanced force, and the electric telescopic rod 27 will not be subjected to force.

[0040] See also Figure 8~Figure 10 The extrusion structure includes a retardation groove 1901 arranged in the driving member 19, and the retardation groove 1901 is provided with two groups, which are respectively located at the two ends of the driving member 19, and a trigger member 20 is slidably installed in the retardation groove 1901, and the sliding direction of the trigger member 20 is perpendicular to the moving direction of the first winding roller 3 in the through groove, and the trigger member 20 is provided with an inclined guide surface 2001, and the trigger member 20 is provided with a locking shaft 21, and the locking shaft 21 is adapted to the locking grooves 2601 equidistantly arranged along the length direction of the locking plate 26; the extrusion structure also includes an energy storage kit connecting the guide frame 2 and the trigger member 20, the The energy storage kit includes a second guide member 25 arranged along the length direction of the guide frame 2, and a follower 24 is slidably installed on the second guide member 25. The follower 24 is slidably connected to the vertical shaft 22 arranged on the trigger member 20, wherein the locking shaft 21 is fixedly installed on the side of the trigger member 20 facing the locking plate 26, and the vertical shaft 22 is fixedly connected to the other side of the trigger member 20, and the vertical shaft 22 and the locking shaft 21 are vertically arranged in space; a second cylindrical spring 23 is sleeved on the vertical shaft 22, one end of the second cylindrical spring 23 is connected to the follower 24, and the other end is connected to the end of the vertical shaft 22.

[0041] In the initial state, since the guide portion 2801 has a supporting effect on the rotating shaft of the first winding roller 3, in this state, the rotating shaft of the first winding roller 3 can be in a separated state from the trigger member 20. At this time, under the action of the second cylindrical spring 23, the trigger member 20 is in a state of being inserted into the lower end of the retardation groove 1901, so that the locking shaft 21 can be embedded in the locking groove 2601, so that the driving member 19 can remain in a locked state, ensuring that when the first winding roller 3 is in this position, the hydraulic cylinder 6 does not need to provide support force to it, and when it is necessary to adjust the tension of the traction cable 5, the control The electric telescopic rod 27 can drive the stopper 28, so that the first winding roller 3 can move to the lower end along the length direction of the through groove, and under the interaction of the inclined guide surface 2001, the trigger member 20 is pushed upward. During this process, the second cylindrical spring 23 is further compressed, and at the same time, the locking shaft 21 can be separated from the locking groove 2601. After the hydraulic cylinder 6 drives the first winding roller 3 to move to the predetermined position, the electric telescopic rod 27 can drive the stopper 28 to move in the reverse direction, so that the rotating shaft of the first winding roller 3 is separated from the trigger member 20 again, thereby further locking the rotating shaft of the first winding roller 3.

[0042] Through the above-mentioned arrangement, in the initial state, the rotating shaft of the first winding roller 3 can be locked, so that the hydraulic cylinder 6 does not need to support it, which effectively avoids the hydraulic cylinder 6 being in a high oil pressure state for a long time, causing the hydraulic oil to leak, and improves the durability of the hydraulic cylinder 6. When the position of the first winding roller 3 needs to be adjusted, the cooperation between the stopper 28 and the rotating shaft of the first winding roller 3 can make the rotating shaft of the first winding roller 3 abut against the trigger member 20, and cause the locking shaft 21 to separate from the locking groove 2601, so that the rotating shaft of the first winding roller 3 can be unlocked and can follow the action of the hydraulic cylinder 6 to achieve position adjustment. Subsequently, during the resetting process of the stopper 28, the rotating shaft of the first winding roller 3 can be locked again.

[0043] See also Figure 1~Figure 2 , Figure 4~Figure 7, the elastic support mechanism is arranged on the support frame 1, and the elastic support mechanism includes an elastic buffer assembly and a reverse pulling assembly. When the ship acts on the elastic buffer assembly, the reverse pulling assembly can make the second return part move away from the first return part; the elastic buffer assembly includes a transverse frame 7 fixedly connected to the support frame 1, and a sliding connection member 8 is slidably installed on the transverse frame 7, and the sliding connection member 8 is connected to an extension shaft 9 that runs through the transverse frame 7, and the sliding connection member 8 is slidably connected to a transverse axis 10 arranged on the transverse frame 7; a first columnar spring 11 is sleeved on the transverse axis 10, one end of the first columnar spring 11 is connected to the side wall of the transverse frame 7, and the other end is connected to the sliding connection member 8; the reverse pulling assembly includes a rotating member 13 rotatably installed on the support frame 1, and a first support rod 12 is rotatably installed on the rotating member 13, and the end of the first support rod 12 away from the rotating member 13 is rotatably connected to the sliding connection member 8 The second support rod 14 is also rotatably mounted on the rotating member 13, and the second support rod 14 is connected to the second winding roller 4 through a guiding structure, and the guiding structure includes a first inclined slide groove 101 and a follower plate 15 arranged on the support frame 1, and the follower plate 15 is rotatably connected to the second support rod 14, and a sliding connection part 1501 is arranged on the follower plate 15, and the sliding connection part 1501 is perpendicular to the vertical groove 1502, and the sliding connection part 1501 is slidably connected to the first guide member 16 arranged on the support frame 1; the guiding structure also includes a first roller 17 and a second roller 18 coaxial with the second winding roller 4, specifically, the first roller 17 and the second roller 18 are provided with two groups, and are respectively located at two ends of the second winding roller 4, and the first roller 17 can roll along the vertical groove 1502 arranged on the follower plate 15, and the second roller 18 can roll in the first inclined slide groove 101.

[0044] In the initial state, the extension shaft 9 is in contact with the ship, and the traction cable 5 is connected to the ship and maintained in a taut state. When the ship is affected by external factors and moves toward the extension shaft 9, the extension shaft 9 can drive the sliding connection member 8 to move. At this time, the movement of the ship can be suppressed under the buffering of the first column spring 11. At the same time, when the sliding connection member 8 moves, it can drive the rotating member 13 to rotate through the first support rod 12, and the rotating member 13 can drive the follower plate 15 to move through the second support rod 14 when rotating. Specifically, the follower plate 15 moves toward the ship along the length direction of the first guide member 16. In this process, with the cooperation of the vertical groove 1502 and the first roller 17 and the first inclined slide groove 101 and the second roller 18, the second winding roller 4 can move downward along the length direction of the first inclined slide groove 101, so that the second winding roller 4 can move away from the first winding roller 3, so that when the ship moves toward the extension shaft 9, the traction cable 5 connected to the ship can always maintain a certain tension state.

[0045] To sum up, when in use, the action of the hydraulic cylinder 6 can actively drive the first winding roller 3 to move, and the relative position between the first winding roller 3 and the second winding roller 4 is changed, so as to adjust the tension of the traction cable 5. This process is based on the control system control, and can be understood as a large-scale adjustment in response to the sea environment and the tension of the traction cable 5. When the ship moves slightly, the extension shaft 9 will move, and under the buffering of the first column spring 11, the small movement of the ship can be suppressed, and the position of the second winding roller 4 relative to the first winding roller 3 is changed, so that the traction cable 5 can always maintain a certain tension, so as to improve the stability of the ship.
