[0002] Marine cables are a type of wire and cable used for power, lighting, control, and communication transmission on various ships on rivers and seas and offshore or offshore buildings, including marine power cables, marine control cables, marine communication cables, etc.

[0003] Generally, when laying cables, it is necessary to reserve a certain length of cable. When poor contact or breakage occurs at the connection between the cable and electrical equipment, it is even necessary to cut the interface between the cable and the electrical equipment when repairing and reconnecting the cable. In this case, it is necessary to lengthen the reserved portion of the cable to compensate for the length of the cut portion of the cable. However, after a certain length of cable is reserved, the cable will become loose. When operating on the hull, the loose portion will shake with the hull, which will cause certain dangers. In addition, the shaking of the cable will cause wear, which will reduce its own strength and affect the service life of the cable. Summary of the invention

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] Please refer to 1-8, a high-tensile-resistance optoelectronic composite cable for ships, including a cable body 1, a shell body 2 and a fixed cover 21, the shell body 2 and the fixed cover 21 are detachably connected; it also includes a tensioning assembly, the tensioning assembly includes a plurality of tensioning columns 32, the plurality of tensioning columns 32 are all in contact with the cable body 1, a plurality of guide grooves 22 are provided on the shell body 2, the plurality of guide grooves 22 correspond to the plurality of tensioning columns 32 one by one, and the tensioning columns 32 are slidably arranged in the guide grooves 22; it also includes a tightening assembly, which is used to tighten the tensioning assembly after the cable body 1 is pulled out to prevent the cable body 1 from being pressed by the tensioning columns 32 after being pulled out, and when the cable body 1 is laid, the cable body 1 is placed in a straight line between the tensioning columns 32 on both sides, and the cable body 1 is bent by sliding the tensioning columns 32, leaving a portion of the length of the cable body 1 reserved. The interior of the shell 2 is convenient for the subsequent maintenance of the cable body 1, and it can also prevent the reserved cable body 1 from causing the entire cable body 1 to become loose, avoid the cable body 1 from shaking with the hull, causing danger, and the wear of the cable body 1, thereby improving the safety of the cable body 1; at the same time, when the reserved cable body 1 is pulled out, the abutment of the tensioning assembly by the tightening assembly makes it possible for the tensioning column 32 to not cause long-term pressure on the contact position with the reserved cable body 1 after the cable body 1 is pulled out, thereby improving the service life of the cable body 1; the fixing cover 21 can be installed by bolts, and after the fixing cover 21 is installed on the shell 2, the cable body 1 on the side away from the tightening assembly is clamped and fixed by the fixing cover 21 and the shell 2, and the cable body 1 at one end of the tightening assembly is not clamped and fixed, so that the cable body 1 can be pulled out when needed later.

[0038] Specifically, the tensioning assembly includes a sliding frame 3 slidably arranged on the shell 2, and a connecting rod 31 is arranged between each tensioning column 32 and the sliding frame 3, and the two ends of the connecting rod 31 are rotatably connected to the tensioning column 32 and the sliding frame 3 respectively. In this embodiment, when the sliding frame 3 slides, the tensioning column 32 is caused to slide along the guide groove 22 through the connecting rod 31, and when the cable body 1 is pulled out, the multiple tensioning columns 32 slide synchronously under the action of the sliding frame 3, thereby preventing the cable body 1 from being partially excessively bent due to the sliding of a single tensioning column 32 when the cable body 1 is pulled out, and avoiding damage to the cable body 1 when it is pulled out of the shell 2.

[0039] In an embodiment further provided by the present invention, a first spring 33 is arranged between the sliding frame 3 and the shell 2, and the two ends of the first spring 33 are fixedly connected to the sliding frame 3 and the shell 2 respectively. The first spring 33 is a tension spring. When the cable body 1 is pulled out, the cable body 1 drives the tensioning column 32 to slide, and the tensioning column 32 slides, and the sliding frame 3 is slid through the connecting rod 31 to stretch the first spring 33. By providing the first spring 33, a certain resistance can be provided to prevent the cable body 1 reserved inside the shell 2 from becoming loose during the pulling out process of the cable body 1; and when the cable body 1 is laid, the sliding frame 3 is slid by the reset force of the first spring 33, and the tensioning column 32 is slid by the connecting rod 31 to tension the cable body 1, so that when the cable body 1 is laid, the cable body 1 can be stably reserved in a section inside the shell 2 for subsequent pulling out and use.

[0040] Furthermore, the clamping assembly includes a pressure block 4 slidably arranged on the shell 2, and a friction plate 42 is fixedly arranged on the pressure block 4. The friction plate 42 is in friction contact with the sliding frame 3. An abutment column 41 is rotatably arranged on the pressure block 4, and the abutment column 41 is in contact with the cable body 1. When the cable body 1 is pulled out, the contact position between the cable body 1 and the abutment column 41 is straightened first. During the straightening process, the pressure block 4 is pushed to slide by the abutment column 41, so that the friction plate 42 on the pressure block 4 is separated from the sliding frame 3. At this time, the sliding frame 3 loses the abutment fixation of the friction plate 42. At this time, continuing to pull out the cable body 1 can make the tensioning column 32 slide, and use the connecting rod 31 to make the sliding frame 3 slide.

[0041] Furthermore, a second spring 43 is provided between the pressure block 4 and the shell 2, and two ends of the second spring 43 are fixedly connected to the pressure block 4 and the shell 2 respectively. When the pressure block 4 slides to disengage the friction plate 42 from the sliding frame 3, the second spring 43 is compressed. After the cable body 1 is pulled out, the cable body 1 is released. Under the action of the second spring 43, the pressure block 4 slides and resets, so that the friction plate 42 abuts against the sliding frame 3, and the sliding frame 3 is abutted and fixed. In the process of resetting the pressure block 4, the abutting column 41 pushes the cable body 1, so that the cable body 1 slides a distance into the shell 2, and the sliding frame 3 is fixed to the tensioning column 32, so as to avoid the first spring 33 from extending during the sliding process of the sliding frame 3. After the cable body 1 is pulled out to the required distance, the reset force of the first spring 33 acts on the tensioning column 32 through the sliding frame 3 and the connecting rod 31, causing the tensioning column 32 to apply excessive pressure to the cable body 1, resulting in damage or instability of the cable body 1.

[0042] In an embodiment further provided by the present invention, an inclined block 5 is slidably provided on the shell 2, an inclined groove 34 is provided on the sliding frame 3, the inclined block 5 is engaged with the inclined groove 34, a plurality of third springs 51 are provided between the inclined block 5 and the shell 2, and the two ends of the third spring 51 are respectively fixedly connected to the inclined block 5 and the shell 2; a pressing key 52 is fixedly provided on the locking block, and when the cable is pulled out to the reserved part is completely pulled out, the inclined groove 34 on the sliding frame 3 contacts with the inclined surface of the inclined block 5, so that the inclined block 5 slides to compress the third spring 51, and passes through the inclined block 5, and then under the resetting action of the third spring 51, The inclined block 5 is engaged with the inclined groove 34 to fix the sliding frame 3, preventing the first spring 33 from returning to its original position and causing the tensioning column 32 to slide, causing the cable body 1 to be damaged by the abutment pressure of the tensioning column 32; when laying the cable body 1, the pressing key 52 is pushed to compress the third spring 51, and the inclined block 5 is disengaged from the inclined groove 34. At this time, under the resetting action of the first spring 33, the sliding frame 3 slides, and the tensioning column 32 is caused to slide along the guide groove 22 through the connecting rod 31, and the cable body 1 is bent, and a part of the cable body 1 is reserved in the shell 2, so that it can be used when the cable body 1 needs to be stretched later.

[0043] In the embodiment provided by the present invention, a clamping block 6 is slidably provided on the shell 2, and a push rod 35 is fixedly provided on the sliding frame 3. The push rod 35 and the clamping block are both provided with inclined surfaces and abut against each other through the inclined surfaces; a silicone pad is fixedly provided on the clamping block 6, and when the cable body 1 is pulled out until the reserved part is completely pulled out, the sliding frame 3 slides to the maximum value, and the push rod 35 on the sliding frame 3 abuts against the inclined surface on the clamping block 6 through the inclined surface, and pushes the clamping block 6, so that the clamping block 6 rises to clamp the cable body 1, so as to ensure the stability of the cable body 1 after the cable body 1 is completely pulled out; wherein the silicone pad is used to enable the clamping block 6 to better clamp the cable body 1, and increase the friction force, so that the clamping block 6 clamps the cable body 1 more stably.

[0044] Working principle: when the cable body 1 is stretched, the tensioning column 32 cannot move due to the friction contact between the friction plate 42 and the sliding frame 3. The cable body 1 will first push the pressure block 4 through the abutment column 41 to compress the second spring 43. The pressure block 4 slides to separate the friction plate 42 from the sliding frame 3. At this time, the cable body 1 continues to be pulled out, and the tensioning column 32 slides to relax the cable body 1, and the sliding frame 3 is made to slide through the connecting rod 31. The first spring 33 is stretched, and after the cable body 1 is pulled to the required length, the cable body 1 is relaxed. At this time, under the action of the second spring 43, the pressure block 4 is reset, and the friction plate 42 is abutted against the sliding frame 3 to fix the sliding frame 3, preventing the reset force of the first spring 33 from acting on the cable body 1 through the sliding frame 3 and the connecting rod 31, causing the cable body 1 to be affected by the action of the first spring 33 for a long time, causing damage;

[0045] If the cable body 1 is continuously pulled out until the reserved part is completely pulled out, that is, the cable body 1 is in a stretched state, the sliding frame 3 slides to the maximum value at this time, and the abutting rod 35 on the sliding frame 3 abuts against the inclined surface on the clamping block 6 through the inclined surface, and pushes the clamping block 6 to make the clamping block 6 rise and clamp the cable body 1, so as to ensure the stability of the cable body 1 after the cable body 1 is completely pulled out. At the same time, the inclined groove 34 on the sliding frame 3 contacts the inclined surface of the inclined block 5, so that the inclined block 5 slides to compress the third spring 51 and passes through the inclined block 5. Then, under the resetting action of the third spring 51, the inclined block 5 is engaged with the inclined groove 34 to fix the sliding frame 3, so as to prevent the first spring 33 from resetting and driving the tensioning column 32 to slide, causing the cable body 1 to be compressed and damaged;

[0046] When laying the cable body 1, place the cable body 1 in a straight line between the tensioning columns 32 on both sides, then move the pressure block 4 to compress the second spring 43, and the friction plate 42 is disengaged from the sliding frame 3, and then push the pressing key 52 to compress the third spring 51, and the inclined block 5 is disengaged from the inclined groove 34. At this time, under the resetting action of the first spring 33, the sliding frame 3 slides, and the tensioning column 32 is made to slide along the guide groove 22 through the connecting rod 31, and the cable body 1 is bent, and a part of the cable body 1 is reserved in the shell 2, so that it can be used when the cable body 1 needs to be stretched later. After completing the operation, the fixing cover 21 can be installed.

[0047] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
