DETAILED DESCRIPTION

[0018] 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.

[0019] 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.

[0020] See also Figure 1-Figure 10 In an embodiment of the present invention, a passive compensation ship cable tensioner based on cable state monitoring includes a support 1, and also includes: a fixed cable 8, which is arranged on the support 1 and connected to a winding mechanism installed on the support 1, one end of the fixed cable 8 is connected to a mooring pile, and the other end is connected to a retracting mechanism arranged on the support 1, the retracting mechanism is also connected to a passive compensation driving mechanism arranged on the support 1, and the passive compensation driving mechanism can drive the retracting mechanism to move so as to perform a tightening action on the fixed cable 8; an external cable 10, which is arranged on the support 1 and connected to the retracting mechanism, the external cable 10 is used to connect an external rope, and the retracting mechanism is also connected to two sets of braking mechanisms arranged on the support 1, and the braking mechanism can fix the state of the fixed cable 8 before the retracting mechanism releases the external cable 10.

[0021] Please refer again Figure 4 The support 1 is provided with an assembly seat 25 which is tilted and fixed. The winding mechanism includes a first wire roller 4 and a second wire roller 5 which are arranged in the support 1 and the assembly seat 25. The fixed cable 8 is wound from the lower part of the first wire roller 4 to the upper part of the second wire roller 5, and then wound out from the lower part of the first wire roller 4 and connected to the retracting mechanism. A through slot 2501 is provided on each side of the assembly seat 25. The rotating shaft of the second wire roller 5 passes through the through slot 2501 and is connected to the passive compensation drive mechanism.

[0022] Furthermore, when the passive compensating drive mechanism moves, it can drive the second line roller 5 to move in the assembly seat 25 along the length direction of the assembly seat 25, and accordingly, the second line roller 5 can move away from or close to the first line roller 4. When the second line roller 5 moves away from the first line roller 4, the fixed cable 8 wound between the first line roller 4 and the second line roller 5 will be pulled, and then, the end of the fixed cable 8 away from the mooring pile will generate traction on the retractable mechanism, so that the retractable mechanism pulls the external cable 10 to tighten the external cable 10, thereby achieving the effect of buffering the relative movement of the two hulls caused by waves, thereby improving the safety of the connection.

[0023] The passive compensating driving mechanism includes two first hydraulic cylinders 6 respectively installed on both sides of the support 1, the first hydraulic cylinders 6 are arranged along the length direction of the assembly seat 25, and the movable end of the first hydraulic cylinder 6 is connected to the rotating shaft of the second line roller 5. The cylinder body of the first hydraulic cylinder 6 is connected to a control oil station arranged on the support 1, and the control oil station maintains pressure balance with the cylinder body of the first hydraulic cylinder 6, so that when the external cable 10 is slack, the movable end of the first hydraulic cylinder 6 can drive the second line roller 5 to move away from the first line roller 4 in the assembly seat 25.

[0024] Specifically, two adjacent hulls are moored side by side. Since the ship cable is a non-rigid connection, when encountering larger waves, the two hulls will have a larger fluctuation difference due to the action of the waves, which may cause a larger relative movement of the two hulls, resulting in damage to the mooring system or even damage to the hull. At this time, since in the present application, the control oil station and the inside of the cylinder of the first hydraulic cylinder 6 maintain pressure balance, then, when the external cable 10 is loose, the movable end of the first hydraulic cylinder 6 automatically extends under the action of pressure, driving the second line roller 5 to move away from the first line roller 4 in the assembly seat 25, and the fixed cable 8 will be pulled, and then, the end of the fixed cable 8 away from the mooring pile will generate traction on the retractable mechanism, so that the retractable mechanism pulls the external cable 10 to tighten the external cable 10, realizing dynamic pressure balance, and can adaptively adjust the tension according to the size of the wave and the degree of cable lifting, so that the cable tension is automatically controlled, effectively improving the safety of the connection.

[0025] It should be additionally explained that, in a specific implementation, the tensioner body is installed on the inner hull, the fixed cable 8 is connected to the mooring pile on the shore, and the external cable 10 is connected to another ship adjacent to the inner hull.

[0026] Please refer again Figure 7 and Figure 8The end of the support 1 is also fixed with two first cross arms 2 and two second cross arms 3 arranged opposite to each other, and the retracting mechanism includes a movable seat 11 slidably arranged on the two first cross arms 2 and a third line roller 9 rotatably mounted on the movable seat 11. The external cable 10 is wound around the third line roller 9, the fixed cable 8 is connected to the movable seat 11, the movable seat 11 cooperates with the braking mechanism, and the rotating shaft of the third line roller 9 is connected to the power assembly installed on the two second cross arms 3.

[0027] When it is necessary to release the connection between the two hulls (i.e., untie the cable), the power component will work and will first drive the brake mechanism to move, and the brake mechanism will lock the position of the movable seat 11, so that the state of the fixed cable 8 is maintained, and the control oil station and the cylinder body of the first hydraulic cylinder 6 are locked in a pressure balance state, and then the power component will drive the third line roller 9 to rotate, so that the third line roller 9 will release the external cable 10, so that the external cable 10 is loose, thereby facilitating the staff to remove the ropes and avoiding the inconvenience of rope removal due to the tension of the external cable 10; further, the position of the movable seat 11 is not locked, and the third line roller is directly driven. 9 rotates, in order to achieve pressure balance inside the cylinder of the control oil station and the first hydraulic cylinder 6, the external cable 10 will be tightened again, making it difficult for the external cable 10 to obtain effective slack; when the external cable 10 is too tight, when the rope is removed, the rope is subjected to excessive tension, which causes inconvenience to the removal work, and after removal, the external cable 10 and the rope are prone to rebound quickly due to the instant release of the tension state, which is easy to cause danger to the staff. For this reason, the present application is provided with a braking mechanism, first braking the movable seat 11, and then the third wire roller 9 releases the external cable 10, so that the rope connection end is relaxed, thereby facilitating the rope removal work and improving the safety of the work. In addition, due to the existence of the braking mechanism, after the external cable 10 is removed, the movable seat 11 and the support 1 remain fixed, so that the first hydraulic cylinder 6 can still adjust and maintain the state of the fixed cable 8 to ensure the mooring stability of the fixed cable 8.

[0028] Please refer again Fig. 9 and Fig.10The power assembly includes a boosting structure installed between the two second cross arms 3 and a sliding sleeve structure connected to the boosting structure. The boosting structure can drive the sliding sleeve structure to move along the length direction of the second cross arm 3 and promote the rotation of the third line roller 9. The sliding sleeve structure includes a transmission shaft 14 rotatably installed between the two second cross arms 3 and a follower tube 15 rotatably installed on the movable seat 11 and slidingly sleeved with the transmission shaft 14. The follower tube 15 is connected to the rotating shaft of the third line roller 9 through a bevel gear set 13. The outer wall of the transmission shaft 14 is formed with two protrusions 1401, and the inner wall of the follower tube 15 is provided with two grooves 1501 adapted to the protrusions 1401, and the transmission shaft 14 is connected to the boosting structure.

[0029] Specifically, the bevel gear set 13 includes a first bevel gear fixedly mounted on the follower tube 15 and a second bevel gear fixedly mounted coaxially with the third line roller 9 , and the second bevel gear is meshed with the first bevel gear.

[0030] During the mooring process of the hull, when the external cable 10 is loose, the movable end of the first hydraulic cylinder 6 automatically extends under the action of pressure, and the fixed cable 8 will pull and tighten the external cable 10 through the movable seat 11. Correspondingly, the movable seat 11 drives the follower tube 15 to slide on the transmission shaft 14. Therefore, the position of the third line roller 9 changes. The setting of the protrusion 1401 and the groove 1501 can ensure that the subsequent boosting mechanism can smoothly drive the third line roller 9 to rotate through the transmission shaft 14 and the follower tube 15 without affecting the position change of the third line roller 9.

[0031] The boosting structure includes two second hydraulic cylinders 7 installed on the inner side of the support 1, a connecting frame 19 fixedly connecting the movable ends of the two second hydraulic cylinders 7, and a second driving sleeve 22 fixed on the connecting frame 19. The second driving sleeve 22 is slidably fitted with the retractable shaft 18 rotatably installed between the two second cross arms 3. The retractable shaft 18 is connected to the transmission shaft 14 through a first transmission belt 16, and a groove body is provided on the outer wall of the retractable shaft 18. A driving column adapted to the groove body is fixedly provided on the inner wall of the second driving sleeve 22. The driving column extends into the groove body and is slidably connected to the retractable shaft 18. The groove body includes a first slide groove 1801 and a second slide groove 1802 connected to each other. The first slide groove 1801 is arranged along the axial direction of the retractable shaft 18, and the second slide groove 1802 is arranged along the spiral.

[0032] During operation, the second hydraulic cylinder 7 actively moves to push the connecting frame 19 to drive the second driving sleeve 22 to slide on the retracting shaft 18 along the axial direction of the retracting shaft 18. Correspondingly, the driving column on the inner wall of the second driving sleeve 22 makes a linear motion along the axial direction of the retracting shaft 18. The driving column first passes through the first sliding groove 1801. During this process, the retracting shaft 18 does not rotate, and the braking mechanism locks the position of the movable seat 11. Then, the driving column passes through the second sliding groove 1802 and slides with the retracting shaft 18 to cause the retracting shaft 18 to rotate. Then, the retracting shaft 18 drives the transmission shaft 14 to rotate through the first transmission belt 16, and the transmission shaft 14 drives the follower tube 15 to rotate through the protrusion 1401 and the groove 1501. The follower tube 15 drives the third line roller 9 to rotate through the bevel gear set 13, so that the external cable 10 is loosened, which is convenient for the staff to safely remove the rope.

[0033] Please refer again Fig. 9 The brake mechanism includes a brake shaft 20 rotatably mounted on the second cross arm 3 and a first drive sleeve 21 fixed on the connecting frame 19 and slidably fitted with the brake shaft 20. A boss 2101 is fixedly provided on the first drive sleeve 21. A folding groove adapted to the boss 2101 is provided on the outer wall of the brake shaft 20. The boss 2101 extends into the folding groove and is slidably connected to the brake shaft 20. The brake shaft 20 is connected with a locking structure. The folding groove includes a first groove section 2001 and a second groove section 2002 connected to each other. The first groove section 2001 is arranged along a spiral, and the second groove section 2002 is arranged along the axial direction of the brake shaft 20.

[0034] The locking structure includes a follower shaft 23 rotatably mounted on the second cross arm 3 and connected to the brake shaft 20 via a second transmission belt 17, and a plurality of brake rods 24 fixedly mounted on the follower shaft 23. The plurality of brake rods 24 are evenly distributed along the axial direction of the follower shaft 23. The brake rods 24 cooperate with a protruding block 12 fixedly mounted on the side of the movable seat 11, and an inclined surface is formed on each side of the protruding block 12.

[0035] Specifically, when the second hydraulic cylinder 7 drives the connecting frame 19 to drive the second driving sleeve 22 to slide on the retracting shaft 18, the first driving sleeve 21 slides on the brake shaft 20. When the driving column on the inner wall of the second driving sleeve 22 passes through the first sliding groove 1801, the protruding column 2101 slides with the brake shaft 20 through the first groove section 2001, causing the brake shaft 20 to rotate. Then, the brake shaft 20 drives the follower shaft 23 to rotate through the second transmission belt 17, and multiple brake rods 24 deflect downward. Therefore, two adjacent brake rods 24 will act on the two sides of the protruding block 12 respectively. Since the position of the movable seat 11 on the first cross arm 2 is not fixed, when the brake rod 24 acts on the inclined surface of the side of the protruding block 12, it will cause the protruding block 12 and the movable seat 11 to swing. The second hydraulic cylinder 6 is pressed against the support 2101 and the second hydraulic cylinder 6 is pressed against the support 2102, and the second hydraulic cylinder 6 is pressed against the support 2101 and the second hydraulic cylinder 6 is pressed against the support 2102.
