Description

Technical Field

[0001] This utility model relates to the field of submarine cable transportation, and further to a submarine cable laying length measuring device. Background Technology

[0002] Submarine cables are cables wrapped in insulating material and laid on the seabed for telecommunications transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern submarine cables use optical fibers as the material to transmit telephone and internet signals.

[0003] In the process of laying submarine cables on the seabed, the length of the laid cable is an important technical parameter. In existing technology, the laying length of the submarine cable is usually calculated by setting measuring rollers along the cable's transport path. The measuring rollers are placed below the cable and in contact with its bottom. As the cable moves, they cause the measuring rollers to rotate. By counting the number of rotations of the measuring rollers, the length of the cable that has been traversed can be determined, thus achieving the purpose of measuring the cable length.

[0004] It should be noted that during the actual laying of submarine cables, the cables themselves may deform or be subjected to external stress. When passing the metering rollers, they may float at a certain height and not make contact with the metering rollers, which may cause inaccurate metering by the metering rollers and result in a large measurement error. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to provide a submarine cable laying length measuring device. The measuring roller is positioned above the submarine cable. When the submarine cable passes under the measuring roller, the measuring roller can press against the submarine cable under its own weight, thereby effectively contacting the submarine cable during its movement without being affected by the deformation of the submarine cable, thus improving the accuracy of the measurement results.

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0039] To keep the drawings concise, each figure only schematically shows the parts relevant to the utility model, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled.

[0040] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0041] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] refer to Figures 1 to 5 This application provides a submarine cable laying length measuring device 100, which includes a measuring platform 10, a mounting bracket 20, a rotating arm 30, and a measuring roller 40. The mounting bracket 20 includes a top bracket 21, which is positioned above the measuring platform 10 and maintains a preset distance from it. The top of the rotating arm 30 is rotatably mounted to the top bracket 20. The measuring roller 40 is rotatably mounted to the bottom of the rotating arm 30. When the submarine cable 200 passes through the gap between the measuring roller 40 and the measuring platform 10, the measuring roller 40 presses against the submarine cable 200, and the movement of the submarine cable 200 drives the measuring roller 40 to rotate.

[0044] In this application, the measuring roller 40 is disposed above the submarine cable 200. When the submarine cable 200 passes under the measuring roller 40, the measuring roller 40 can press against the submarine cable 200 under its own weight, thereby effectively contacting the submarine cable 200 during its movement and not being affected by the deformation of the submarine cable 200, thus improving the accuracy of the measurement results.

[0045] On the other hand, rotating the rotating arm 30 relative to the mounting bracket 20 can move the metering roller 40, thereby changing the distance between the metering roller 40 and the metering platform 10, thus facilitating the installation and removal of the submarine cable 200. For example, before the submarine cable is laid, when it is necessary to place the end of the submarine cable 200 between the metering roller 40 and the metering platform 10, the rotating arm 30 is rotated to increase the distance between the metering roller 40 and the metering platform 10. Then, the end of the submarine cable 200 is placed in the gap between the metering roller 40 and the metering platform 10, and then the rotating arm 30 is released. Under the influence of the gravity of the metering roller 40, the rotating arm 30 rotates relative to the mounting bracket 20, and the metering roller 40 automatically falls and presses against the submarine cable 200.

[0046] Preferably, when the measuring roller 40 abuts against the surface of the submarine cable 200, the rotating arm 30 has a preset angle relative to the vertical plane, so that the weight of the measuring roller 40 can be fully applied to the submarine cable, and the rotating arm 30 will not provide tension to the measuring roller 40, thereby improving the pressure resistance on the submarine cable 200.

[0047] refer to Figure 1 and Figure 2 Furthermore, the submarine cable laying length measuring device 100 further includes a first support roller 51 and a second support roller 52. The first support roller 51 and the second support roller 52 are rotatably mounted on the top surface of the measuring platform 10 at a predetermined distance from each other. The axis of the first support roller 51 and the axis of the second support roller 52 are parallel to each other and parallel to the top surface of the measuring platform 10. A conveying channel 41 is formed between the plane containing the top of the first support roller 51 and the top of the second support roller 52 and the bottom of the measuring roller 40, and the submarine cable 200 is adapted to pass through the conveying channel 41.

[0048] As the submarine cable 200 passes through the conveying channel 41, its top contacts the metering roller 40, and its bottom contacts the first support roller 51 and the second support roller 52. The first support roller 51 and the second support roller 52 provide support for the submarine cable 200, reducing the resistance as it passes between the metering roller 40 and the metering platform 10, thus facilitating its passage between them.

[0049] The submarine cable laying length measuring device 100 further includes a first limiting roller 53 and a second limiting roller 54. The first limiting roller 53 and the second limiting roller 54 are rotatably mounted on the top surface of the measuring platform 10 at a predetermined distance from each other. The axis of the first limiting roller 53 and the axis of the second limiting roller 54 are parallel to each other and perpendicular to the top surface of the measuring platform 10. A limiting channel 50 is formed between the first limiting roller 53 and the second limiting roller 54, and the submarine cable 200 is adapted to pass through the limiting channel 50.

[0050] When the submarine cable 200 passes through the measuring platform 10, the measuring roller 40 is positioned above the submarine cable 200, the first support roller 51 and the second support roller 52 are positioned below the submarine cable 200, and the first limiting roller 53 and the second limiting roller 54 are positioned on the left and right sides of the submarine cable 200, respectively, thereby limiting the submarine cable 200 in four directions: up, down, left, and right. Furthermore, it should be noted that by limiting the submarine cable 200 on the left and right sides using the first limiting roller 53 and the second limiting roller 54, the violent swaying of the submarine cable 200 as it passes the measuring roller 40 can be prevented from causing the measuring roller 40 to roll, thus improving the accuracy of length measurement.

[0051] refer to Figure 1 , Figure 2 as well as Figure 3 Furthermore, the outer surfaces of the measuring roller 40, the first support roller 51, the second support roller 52, the first limiting roller 53, and the second limiting roller 54 are all arc-shaped surfaces that are lower in the middle and higher at both ends. When the submarine cable comes into contact with the measuring roller 40, the first support roller 51, the second support roller 52, the first limiting roller 53, and the second limiting roller 54, the structure of the rollers being lower in the middle and higher at both ends can limit the movement of the submarine cable 200, increase the resistance of the submarine cable 200 to axial movement along the outer circumference of the rollers, and improve the accuracy of submarine cable measurement.

[0052] In some embodiments, the first support roller 51 is also a roller with a measuring function. That is, when the submarine cable 200 moves within the conveying channel 41, the submarine cable 200 can simultaneously drive the measuring roller 40 and the first support roller 51 to rotate. Both the measuring roller 40 and the first support roller 51 have length measuring functions, meaning they can count their own rotations, and the rotation radius is known. Based on the number of rotations and the rotation radius, the length of the submarine cable 200 that has passed can be calculated. Since both the measuring roller 40 and the first support roller 51 have measuring functions, they can serve as backups for each other and calibrate against each other. If one is damaged, the other can still measure, without affecting the construction progress. On the other hand, by comparing the length data obtained by the measuring roller 40 and the first support roller 51 respectively, if the error between the two exceeds a preset value, one of them may be damaged, prompting the user to perform timely repairs. On the other hand, when the difference in length measured by the measuring roller 40 and the first support roller 51 is within a preset range, the average of the length results obtained by the two measurements is taken, thereby reducing the error inherent in the measuring structure itself and improving the accuracy of the measurement results.

[0053] refer to Figure 1 , Figure 2 as well as Figure 3 Specifically, the submarine cable laying length measuring device 100 further includes two first lugs 61 and two second lugs 62 installed on the top surface of the measuring platform 10. The two first lugs 61 are spaced apart by a preset distance, and the two second lugs 62 are also spaced apart by a preset distance. There is also a certain distance between the two first lugs 61 and the two second lugs 62. The two ends of the first support roller 51 are rotatably mounted on the two first lugs 61, and the two ends of the second support roller 52 are rotatably mounted on the two second lugs 62.

[0054] Specifically, the second lug 61 has a first rotating hole 610 at a predetermined position, and the second lug 62 has a second rotating hole 620 at a predetermined position. The first support roller 51 has a first rotating shaft 511 at each end, and the two first rotating shafts 511 of the first support roller 51 are rotatably installed in the two first rotating holes 610. The second support roller 52 has a second rotating shaft 521 at each end, and the two second rotating shafts 521 are rotatably installed in the two second rotating holes 620.

[0055] The submarine cable laying length measuring device 100 further includes a first support block 71, a second support block 72, and a connecting rod 73. The first support block 71 and the second support block 72 are installed on the top surface of the measuring platform 10 at a predetermined distance from each other. The bottom of the first limiting roller 53 is rotatably mounted on the first support block 71, the bottom of the second limiting roller 54 is rotatably mounted on the second support block 72, one end of the connecting rod 73 is rotatably mounted on the top of the first limiting roller 53, and the other end of the connecting rod 73 is rotatably mounted on the top of the second limiting roller 53.

[0056] refer to Figure 1 , Figure 2 as well as Figure 3 Furthermore, the mounting bracket 20 further includes a first side bracket 22 and a second side bracket 23, which are respectively disposed on both sides of the measuring platform 10. One end of the top bracket 20 is installed on the top of the first side bracket 22, and the other end is installed on the top of the second side bracket 23.

[0057] The rotating arm 30 includes a first rotating arm 31 and a second rotating arm 32. The top support 21 has a first ear plate 211 and a second ear plate 212 spaced apart at a predetermined position. The top of the first rotating arm 31 is rotatably mounted to the first ear plate 211, and the top of the second rotating arm 32 is rotatably mounted to the second ear plate 212. The bottom of the first rotating arm 31 is rotatably mounted to one side of the metering roller 40, and the bottom of the second rotating arm 32 is rotatably mounted to the other side of the metering roller 40. The rotating arms 30 on both sides of the metering roller 40 improve the stability of the metering roller 40 during operation.

[0058] refer to Figure 1 and Figure 2Furthermore, the submarine cable laying length measuring device 100 further includes a tensioning mechanism 80, which includes a first tensioning sprocket 81 and a second tensioning sprocket 82 spaced at a predetermined distance in the vertical direction. A tensioning channel 83 is formed between the first tensioning sprocket 81 and the second tensioning sprocket 82, and the submarine cable 200 is installed in the tensioning channel 83. The surface of the first tensioning sprocket 81 includes a plurality of spaced-apart first tensioning blocks 811, and the surface of the second tensioning sprocket 82 includes a plurality of spaced-apart second tensioning blocks 821. Both the first tensioning blocks 811 and the second tensioning blocks 821 have a structure that is low in the middle and high at both ends, and the tensioning channel 83 is formed between the first tensioning blocks 811 and the second tensioning blocks 821. By designing the first tensioning blocks 811 and the second tensioning blocks 821 to have a structure that is low in the middle and high at both ends, it is easier to accommodate the circular submarine cable 200 and improve the stability of the submarine cable 200 between the first tensioning sprocket 81 and the second tensioning sprocket 82.

[0059] refer to Figure 4 and Figure 5 Specifically, during the submarine cable laying process, the submarine cable 200 is positioned between the first tensioning sprocket 81 and the second tensioning sprocket 82 to tension the cable during laying. When the first tensioning sprocket 81 and the second tensioning sprocket 82 rotate, they can move the submarine cable 200 located between them, thereby enabling the release of the cable. Preferably, the metering platform 10, the mounting bracket 20, the rotating arm 30, and the metering roller 40 are located on the side of the opening where the tensioning mechanism 80 ejects the submarine cable; in some embodiments, they can also be located on the side where the tensioning mechanism 80 inserts the submarine cable; or in some embodiments, they can be located on both the side where the tensioning mechanism 80 inserts the submarine cable and the side where it ejects the cable.

[0060] refer to Figure 6According to another aspect of this application, a submarine cable laying length measuring device is further provided, including a measuring platform 10, a mounting bracket 20, a rotating arm 30, a measuring roller 40, and a pressing roller 90. The mounting bracket 20 includes a top bracket 21, which is disposed above the measuring platform 10 and maintains a preset distance from the measuring platform 10. The top of the rotating arm 30 is rotatably mounted to the top bracket 21. The measuring roller 40 is rotatably mounted to the top surface of the measuring platform 10. The pressing roller 90 is rotatably mounted to the bottom of the rotating arm 30. When the submarine cable 200 passes through the gap between the pressing roller 90 and the measuring roller 40, the pressing roller 90 presses against the submarine cable 200, and the movement of the submarine cable 200 can drive the measuring roller 40 to rotate. In this embodiment, the measuring roller 40 is disposed below the submarine cable 200, and the pressing roller 90 is disposed above the submarine cable 200. When the submarine cable 200 passes through the gap between the pressure roller 90 and the measuring roller 40, the pressure roller 90 presses against the submarine cable 200 under its own weight, so that the submarine cable 200 presses against the measuring roller 40, ensuring full contact with the measuring roller 40 during movement and improving the accuracy of the measurement results. In this embodiment, except for the change in the setting position of the measuring roller 40 and the placement of the pressure roller 90 above the submarine cable 200, the rest of the structure is similar to the above embodiment and will not be described again here.
