Description

Technical Field

[0001] The present invention relates to the technical field of cable storage devices, and in particular to a retractable submarine cable guide storage device and a control method thereof. Background Art

[0002] Cables are typically stored on cable reels, wound onto appropriately sized reels for road transport (maximum diameter 4.5 meters). However, submarine cables are often ordered in long lengths (up to tens of kilometers), and ordinary cable reels are insufficient for storage and transportation. Therefore, submarine cables are typically stored on large-capacity pallets (up to 30 meters in diameter) and transported and laid using specialized submarine cable laying vessels.

[0003] Currently, domestic submarine cable voltage levels are gradually increasing, and nominal cross-sections are larger than in previous submarine cable projects, placing higher demands on the bending radius of submarine cables. Especially during type testing and pre-qualification testing of submarine cables, since submarine cable samples are generally transported by land to third-party testing institutions, smaller-diameter cable reels cannot meet the required bending radius, and the reel length also makes it difficult to meet testing requirements. Therefore, pallets are a more optimal storage and transportation method.

[0004] Currently, most traditional rotating pallets are circular, and large-diameter pallets meet the sea transportation requirements for long-length submarine cables. However, there are transportation restrictions when using land transportation. A new pallet design is needed to ensure that land transportation to third-party testing institutions meets the width and height restrictions, facilitates cable reeling and unreeling operations, and meets the cable length required for the test.

[0005] Furthermore, after submarine cable test samples are produced, they must be stored on in-plant reels before being transported to the high-voltage testing room for partial discharge and voltage testing. Qualified submarine cables are then transported to the packaging site for factory packaging before being sent to a third-party testing agency for further testing. While large-diameter reels can be used for in-plant transportation, these oversized reels would not meet land transportation restrictions.

[0006] As the voltage level increases, the length of the cable installed in the test equipment is required to be longer during testing. If the conventional method is used to lay out the cable, the length of the sample at both ends is short, which is not convenient for installing the test equipment.

[0007] According to the current configuration of domestic third-party testing institutions, the tension and bending tests in type testing are all arranged to be conducted in-house by submarine cable manufacturers. Therefore, after passing the test, the submarine cable needs to be paid out and loaded onto the test wheel. After the test, it is reeled in. Considering this testing process, the following solution can be adopted: after the submarine cable sample is produced, it is not reeled in. Instead, a transfer cart is used to tow the full length of the submarine cable sample to the test room for testing. After passing the test, it is towed out of the test room and towed to the tension and bending test site. After the test is completed, it is towed to the packaging site for shipment and packaging.

[0008] Although the above solution avoids the problem of submarine cable length of the test equipment, the submarine cable is dragged on the ground three times throughout the entire process. If there is no reasonable transfer channel, there will be additional transfer risks and low efficiency. In addition, the test hall site is difficult to meet the testing requirements of hundreds of meters of submarine cables. The submarine cable can be divided into several sections for separate testing, but this further reduces the test efficiency.

[0009] Therefore, in summary, whether choosing a large-diameter turnover plate in the factory or using a transfer cart for ground dragging, neither solution can solve the limitation of land transportation when sending to a third-party testing organization for inspection, and both solutions have limitations.

[0044] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0045] The foregoing and other technical aspects, features, and functions of the present invention will be more clearly understood in the following detailed description of the embodiments with reference to the accompanying drawings. Directional terms such as up, down, left, right, front, and back, used in the following embodiments, are merely references to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes only and are not intended to limit the present invention. Furthermore, throughout the embodiments, the same reference numerals denote the same elements.

[0046] Example 1:

[0047] Combine Figures 1-8 , a retractable submarine cable guide and storage device, comprising

[0048] The cable storage tray 1 comprises an annular crawler track 101 , which rotates around its center.

[0049] At least one cable guide device is arranged in the space surrounded by the crawler track 101, and includes a cable guide arm and a cable guide lifting and rotating base, which is connected to the cable guide arm through a rotating wheel. When the cable guide lifting and rotating base rotates around its center, the cable guide arm rotates around the rotating wheel.

[0050] In this embodiment, there are two cable guides. Compared with only one cable guide, two cable guides are provided to more effectively clamp and transport the submarine cable 8. For the convenience of description, the two cable guides are defined as a first cable guide 3 and a second cable guide 5. Therefore, the first cable guide 3 includes a first cable guide arm 301 and a first lifting and rotating base 302, and the first lifting and rotating base 302 is connected to the first cable guide arm 301 through a first rotating wheel 303. The second cable guide 5 includes a second cable guide arm 501 and a second lifting and rotating base 502, and the second lifting and rotating base 502 is connected to the second cable guide arm 501 through a second rotating wheel 503.

[0051] Traction device 4, located within the interior space enclosed by crawler tracks 101, comprises a tractor 401 and a traction lift rotary base 402. Tractor 401 is mounted on traction lift rotary base 402. The traction lift rotary base rotates about its center. Tractor 401 is a commercially available cable conveyor, the model and power of which can be selected and adjusted by those skilled in the art as needed. Tractor 401 is suitable for laying large-section, long-distance cables, reducing labor intensity and improving construction quality. The cable conveyor boasts high thrust, a compact size, light weight, and ease of operation, making it particularly suitable for applications such as cable conduits, tunnels, straight lines, and long-distance transport.

[0052] The linear module 6 includes a drive device and a slide connected to the drive device. The cable guide lifting and rotating base and the traction lifting and rotating base 402 are arranged on the slide of the same linear module 6 or on the slides of different linear modules 6 arranged in parallel. The slide reciprocates horizontally along the length direction of the cable storage tray 1.

[0053] When the cable guide device and the traction device 4 are synchronously raised or lowered, the cable guide device leads in or leads out the submarine cable 8 , and the submarine cable 8 is led into or led out of the cable storage tray 1 through the traction device 4 .

[0054] In this embodiment, the crawler track 101 is disposed on a circular runway slide rail 104 , and the runway slide rail 104 defines a bottom cable outlet 105 .

[0055] In this embodiment, the cable storage tray 1 further comprises a steel drum, which is fixedly supported by guide wheel type pillars 102, and the guide wheel type pillars 102 are vertically fixed on the crawler track 101. The crawler track 101 is provided on the bearing plate.

[0056] In this embodiment, the cable storage tray 1 further includes a fence 103, which is arranged along the circumference of the steel drum and welded to the steel drum. The height of the fence 103 can be set according to the required reeling height, and the fence 103 is used to limit the reeling position of the submarine cable 8.

[0057] In this embodiment, the cable-guided lift rotary base and the traction lift base 402 both include a rotating platform and a lifting seat. The lifting seat supports the rotating platform, and the bottom of the lifting seat is disposed on the slide of the linear module 6. The specific structure of the cable-guided lift rotary base and the traction lift base 402 can be referenced to the structure and working principle of a rotary lift disclosed in Chinese Utility Model Patent (CN207596384U), and will not be repeated here.

[0058] In this embodiment, the fairlead arm has a curvature for easy storage, and at least one wire guide wheel is provided on the fairlead arm. Correspondingly, a plurality of first wire guide wheels 3011 are provided on the first fairlead arm 301, and the plurality of first wire guide wheels 3011 are arranged along the length direction of the first fairlead arm 301, and the spacing between two adjacent first wire guide wheels 3011 is the same; a plurality of second wire guide wheels 5011 are provided on the second fairlead arm 501, and the plurality of second wire guide wheels 5011 are arranged along the length direction of the second fairlead arm 501, and the spacing between two adjacent second wire guide wheels 5011 is the same. The first wire guide wheels 3011 and the second wire guide wheels 5011 assist the submarine cable 8 in passing through the first fairlead arm 301 and the second fairlead arm 501.

[0059] In this embodiment, the cable guide device further includes a receiving sliding wheel, which is provided at one end of the cable guide arm and slides passively via the cable guide arm. Correspondingly, a first receiving sliding wheel 304 is provided on the first cable guide arm 301 and slides passively via the first cable guide arm 301; a second receiving sliding wheel 504 is provided on the second cable guide arm 501 and slides passively via the second cable guide arm 501.

[0060] In this embodiment, the driving device and the slide are connected via a synchronization module, which is a synchronous belt type module and a screw type module.

[0061] The working principle of the synchronous belt module is as follows: the belt is installed on the drive shaft on both sides of the linear module 6, which serves as the power input shaft. A clamping block for adding equipment workpieces is fixed to the belt. The clamping block is connected to the slide. When there is a power source input, it drives the belt to move the slide. Usually, the synchronous belt linear module is designed to control the tightness of the belt movement on one side, which facilitates the debugging of the equipment during the production process. The synchronous belt linear module can choose to add rigid guide rails to improve the rigidity of the linear module according to different load requirements. Different specifications of linear modules 6 have different load limits.

[0062] The working principle of the screw type module is as follows: converting rotary motion into linear motion, or converting linear motion into rotary motion.

[0063] In this embodiment, the retractable submarine cable guide and storage device further includes an operating system 7 , which is connected to the cable storage tray 1 , the cable guide device and the traction device 4 , and controls the cable storage tray 1 , the cable guide device and the traction device 4 .

[0064] In this embodiment, the retractable submarine cable guide and storage device further includes a power chassis 2, which is loaded with a cable storage tray 1, a cable guide device and a traction device 4. A bottom guide wheel frame 106 is provided between the power chassis 2 and the cable storage tray 1. The bottom guide wheel frame 106 facilitates the crawler track 101 to drive the bottom guide wheel frame 106 to move, and the power chassis 2 transports the submarine cable 8.

[0065] The above provides a retractable submarine cable guide and storage device that meets the turnover and testing needs of submarine cable samples in the factory, meets the land transportation requirements of submarine cables, reduces transportation risks, and improves work efficiency.

[0066] Example 2:

[0067] A control method for a retractable submarine cable guide and storage device comprises the following steps:

[0068] In the initial state, the cable guiding device and the traction device 4 are both placed horizontally and stored in the cable storage tray 1 .

[0069] When winding or releasing the line, the cable guide device and the traction device 4 are respectively raised by the cable guide lifting rotary base and the traction lifting rotary base 402 to a height that meets the outer diameter requirement of the reeled submarine cable 8. The cable guide arm, the traction machine 401 and the cable storage tray 1 cooperate with each other to wind up or release the line.

[0070] When the line is taken up or paid out, the cable guide device and the traction device 4 are lowered by the cable guide lifting and rotating base and the traction lifting and rotating base 402 respectively to return to the initial state.

[0071] The specific working process of the device provided in combination with Example 1 is as follows:

[0072] (1) Initial state: There is no submarine cable in the cable storage tray 1, and the first cable guide device 3, the traction device 4, and the (5) 2# cable guide device are all placed horizontally and stored in the cable storage tray 1, which is convenient for transportation and storage in the factory, waiting for the next cable storage demand.

[0073] (2) Retracting and releasing line status

[0074] (2.1) When reeling in the cable: the first cable guide 3, the traction device 4, and the second cable guide 5 are respectively raised by the first lifting and rotating base 302, the traction lifting and rotating base 402, and the second lifting and rotating base 502 to a height that meets the outer diameter requirement of the reeled submarine cable 8;

[0075] The first cable guide 3 slides leftward to a suitable position through the linear module 6 from the initial position and rotates clockwise at a certain angle, which is required to meet the requirements for winding the submarine cable 8;

[0076] The traction device 4 rotates a certain angle clockwise by pulling the lifting and rotating base 402 in the initial position;

[0077] The second cable guide 5 slides rightward to a suitable position through the linear module 6 from the initial position and rotates clockwise at a certain angle, which is required to meet the requirements for winding the submarine cable 8;

[0078] The rotation angles of the first cable guide device 3, the traction device 4 and the second cable guide device 5 should cooperate with each other, and the path formed meets the following requirements: the first cable guide device 3 introduces the submarine cable 8 from the left side, enters the second cable guide device 5 through the traction device 4, and is then introduced into the cable storage tray 1. From the top-down observation angle, the submarine cable as a whole should be an approximately straight path. In order to save land transportation space, the path of the submarine cable 8 can be slightly curved. The path of the submarine cable for this take-up is recorded, and the second cable guide device 5 can be adaptively rotated to facilitate the arrangement of the submarine cable 8 on the cable storage tray 1.

[0079] After the path is determined, the tractor 401 of the traction device 4 and the track 101 of the cable storage tray 1 are activated to begin reeling in the cable. The first 8-10 meters of cable is passed through the bottom cable outlet 105 and into the bottom guide wheel frame 106, preparing for subsequent partial discharge and voltage testing on the cable storage tray 1. If these tests are not required, the entire submarine cable 8 can be placed inside the cable storage tray 1.

[0080] (2.2) After the line is collected:

[0081] After the first cable guide 3, the traction device 4, and the second cable guide 5 are rotated to a horizontal state via their respective lifting and rotating bases, the first cable guide 3 slides rightward to its initial position via the linear module 6. After the lifting and rotating base descends and the storage sliding wheel touches the surface of the tray, the rotating wheel passively rotates, separating the fairlead arm from the lifting and rotating base. As the height of the fairlead arm descends, the storage sliding wheel passively slides on the tray, allowing the fairlead arm to meet the storage height requirement. The traction device 4 descends via the lifting and rotating base, allowing the traction machine to meet the storage height requirement.

[0082] The second cable guide device 5 slides to the left to the initial position through the linear module 6, and after the lifting and rotating base descends, the storage sliding wheel touches the surface of the tray, and the rotating wheel passively rotates to separate the cable guide arm from the lifting and rotating base. As the height of the cable guide arm decreases, the storage sliding wheel passively slides on the tray, so that the cable guide arm meets the storage height requirement.

[0083] At this point, the cable is collected and the pallet status changes to a loaded state, which is convenient for transportation conditions such as transshipment within the submarine cable factory, packaging and inspection by a third-party testing agency, etc.

[0084] (2.3) When paying out the line:

[0085] The first cable guide device 3, the traction device 4 and the second cable guide device 5 are respectively raised by the first lifting and rotating base 302, the traction lifting and rotating base 402 and the second lifting and rotating base 502 to a height that meets the outer diameter requirement of the submarine cable to be released;

[0086] The first cable guide 3 slides leftward to a suitable position through the linear module 6 from the initial position and rotates clockwise at a certain angle that meets the requirements for unwinding the submarine cable 8;

[0087] The traction device 4 rotates a certain angle clockwise by pulling the lifting and rotating base 402 in the initial position;

[0088] The second cable guide 5 slides leftward to a suitable position through the linear module 6 from the initial position and rotates clockwise at a certain angle, which is required to meet the requirements for unwinding the submarine cable 8;

[0089] The rotation angles of the first cable guide 3, the traction device 4, and the second cable guide 5 should cooperate with each other, and the path formed should meet the following requirements: the second cable guide 5 introduces the submarine cable from the right side, enters the first cable guide 3 through the traction device 4, and leads the submarine cable 8 out of the cable storage tray 1. From a top-down perspective, the pay-out path should be consistent with the take-up path, and the second cable guide 5 can be adaptively rotated to facilitate the pay-out of the submarine cable 8 from the cable storage tray 1.

[0090] After the path is determined, the traction machine 401 of the traction device 4 is started to start paying out the line.

[0091] (2.4) After the line is laid:

[0092] After the first cable guide 3, the traction device 4, and the second cable guide 5 are rotated to a horizontal state by the first lifting and rotating base 302, the traction lifting and rotating base 402, and the second lifting and rotating base 502, respectively, the first cable guide 3 slides rightward to the initial position through the linear module 6. After the first lifting and rotating base 302 descends and the first storage sliding wheel 304 touches the bottom surface of the cable storage tray 1, the first rotating wheel 303 passively rotates, causing part of the first cable guide arm 301 to separate from the first lifting and rotating base 302. As the height of the first cable guide arm 301 descends, the first storage sliding wheel 304 passively slides on the cable storage tray 1, causing the first cable guide arm 301 to meet the storage height requirement. The traction device 4 descends through the traction lifting and rotating base 402, causing the traction machine 401 to meet the storage height requirement. The second cable guide device 5 slides to the left to the initial position through the linear module 6, and after the second lifting and rotating base 502 descends, the second storage sliding wheel 504 touches the surface of the cable storage tray 1, and the second rotating wheel 503 passively rotates, so that part of the second cable guide arm 501 is separated from the second lifting and rotating base 502. As the height of the second cable guide arm 501 decreases, the second storage sliding wheel 504 passively slides on the cable storage tray 1, so that the second cable guide arm 501 meets the storage height requirement.

[0093] At this point, the cable payout is completed, and the state of the cable storage tray 1 is changed to the initial state, which is convenient for transportation and storage within the factory, waiting for the next cable storage demand.
