Description

Technical Field

[0001] This invention relates to the field of submarine cable operation and maintenance technology, specifically to a submarine cable operation and maintenance equipment. Background Technology

[0002] When carrying out maintenance and repair work on submarine cables, it is necessary to determine the faulty section of the submarine cable based on abnormal information, then use a detector to locate the specific fault point of the submarine cable, and then use a submarine cable repair vessel to lift the submarine cable so that the damaged section is placed on the deck for cutting, repair and replacement.

[0003] For example, CN114248889A discloses an AUV suitable for submarine cable inspection, comprising a flat outer shell, with a front compartment, a middle compartment, and a rear compartment inside the shell; each of the front, middle, and rear compartments is equipped with a frame-type support skeleton; the support skeleton is fixed to the bottom of the outer shell, and the support skeleton of the front compartment is connected to the support skeleton of the rear compartment through the support skeleton of the middle compartment or directly to the support skeleton of the rear compartment. This invention uses frame-type support skeletons in different compartments, which allows infrequently used parts to be placed in the support skeleton of the middle compartment during commissioning. During commissioning, only the rear and front compartments are needed for assembly and launching, facilitating commissioning. However, this application and the prior art still have the following problems: 1. The water flow conditions in the sea area are complex. The AUV in this application needs to constantly adjust its own attitude so that it can move along the length of the submarine cable to achieve the effect of inspecting the submarine cable. This is quite difficult. In addition, a large amount of attached material will accumulate on the surface of the submarine cable, which will interfere with the observation of the camera module.

[0004] 2. After the exact location of the submarine cable fault is detected, the damaged submarine cable needs to be lifted onto the deck of the maintenance vessel for repair. However, during the lifting and lowering process, the submarine cable is prone to secondary damage due to bending angles exceeding its safety value, causing further damage to the already damaged submarine cable.

[0005] Based on this, the present invention designs a submarine cable transportation and inspection device to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a submarine cable transportation and inspection device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A submarine cable transportation and inspection device, comprising a first support frame; The first support frame is provided with a receiving groove for placing the submarine cable. An all-round brushing and cleaning mechanism is installed on the side of the first support frame. The all-round brushing and cleaning mechanism includes a circumferential moving component and an axial reciprocating brushing component. The circumferential moving component is installed on the side of the first support frame. The axial reciprocating brushing component is installed at the moving end of the circumferential moving component. The circumferential moving component is used to drive the axial reciprocating brushing component to move circumferentially along the submarine cable. The axial reciprocating brushing component is used to reciprocate brushing the submarine cable radially along the submarine cable. Multiple bending limit support mechanisms are installed along the axial direction of the coastal cable on the left and right sides of the first support frame. Synchronous telescopic mechanisms are installed on the front and rear sides of the first support frame, and the synchronous telescopic mechanisms are connected to all bending limit support mechanisms. The first support frame is also fixedly equipped with a detection device for detecting whether the submarine cable is faulty.

[0008] Furthermore, the axial reciprocating brushing assembly includes a support plate, a brushing motor, a transmission assembly, a drive arm, a cleaning brush, a pushing assembly, and a reciprocating moving assembly. The support plate is slidably connected to the ring shifter, allowing the support plate to slide axially along the cable. The pushing assembly is mounted on the support plate, and a drive arm is rotatably mounted on the moving end of the pushing assembly. Multiple drive arms are evenly spaced axially along the cable. A cleaning brush is fixedly mounted on the end of the drive arm away from the pushing assembly. The brushing motor is fixedly mounted on the support plate, and the output end of the brushing motor is connected to any drive arm via the transmission assembly. Adjacent drive arms are also connected via the transmission assembly. The reciprocating moving assembly is mounted on the support plate.

[0009] Furthermore, the transmission assembly adopts a synchronous belt and synchronous pulley transmission structure. The synchronous pulley of the transmission assembly is rotatably connected to the support plate through bearings, and the synchronous pulley of the transmission assembly is connected to the drive arm through a key, so that the drive arm can rotate synchronously with the synchronous pulley of the transmission assembly and slide along the axial direction of the synchronous pulley.

[0010] Furthermore, the reciprocating moving assembly includes a rotating disk and a connecting plate. The rotating disk is fixedly connected to the output end of the brushing motor, one end of the connecting plate is hinged to the eccentric part of the rotating disk, and the other end of the connecting plate is hinged to the ring moving frame.

[0011] Furthermore, the axial reciprocating scrubbing assembly also includes a water spray pipe, a sliding sleeve, and a water pump. The middle part of the water spray pipe is hinged to the support plate, and a sliding sleeve is hinged to the ring-moving frame. The sliding sleeve is sleeved on the outside of the tail of the water spray pipe and slidably connected to the water spray pipe. The water pump is fixedly connected to the support plate, and the water outlet of the water pump is connected to the water spray pipe.

[0012] Furthermore, the bending limit support mechanism includes a second support frame, a vertical shift support assembly, and a support limiting assembly. The vertical shift support assembly is installed on the second support frame, and the support limiting assembly is installed on the vertical shift support assembly. The vertical shift support assembly is used to enable the support limiting assembly to move vertically along the second support frame.

[0013] Furthermore, the support limiting assembly includes a lower support roller, a side fixed roller, a side movable roller, and a one-way moving assembly. The lower support roller is rotatably mounted at the lower end of the moving end of the vertical moving support assembly, the side fixed roller is rotatably mounted on one side of the moving end of the vertical moving support assembly, and the one-way moving assembly is mounted on the side of the moving end of the vertical moving support assembly away from the side fixed roller, and the side movable roller is mounted on the one-way moving assembly; the lower support roller, the side fixed roller, and the side movable roller are arranged in a triangular pattern.

[0014] Furthermore, the unidirectional movement component includes connecting rods, a pull plate, and a unidirectional control component. The two connecting rods are slidably connected to the moving end of the vertical support component. The ends of the two connecting rods near the side fixed roller are rotatably connected to the side movable roller, and the other ends of the two connecting rods are fixedly connected to the pull plate. The unidirectional control component is installed on the connecting rods.

[0015] Furthermore, the unidirectional control component includes a slot, a locking block, a fixing block, a pull block, and a spring. Multiple slots are evenly spaced along the length of the connecting rod. The fixing block is fixedly connected to the moving end of the vertical support component, and a locking block that engages with the slot is slidably connected to the fixing block. A pull block is fixedly installed on the upper end of the locking block. The spring is sleeved on the outside of the locking block, and its two ends are fixedly connected to the fixing block and the pull block, respectively. Furthermore, the synchronous telescopic mechanism includes a push cylinder and a scissor fork assembly. The push cylinder is fixedly installed at the lower end of the first support frame, and its output end is fixedly connected to a second support frame adjacent to the first support frame. The scissor lift assembly is formed by hinged ends of several scissor lift pieces. Each scissor lift piece includes two scissor lift links and one scissor lift pin. The middle parts of the two scissor lift links are hinged through the scissor lift pin. The several scissor lift pins are respectively fixedly connected to the first support frame and several corresponding second support frames.

[0016] Compared to existing technologies, the advantages of this invention are as follows: The device is deployed to the area of ​​the submarine cable exhibiting abnormal information. The first support frame and the bending limit support mechanism are placed outside the submarine cable. The bending limit support mechanism then drives the entire device to move along the length of the submarine cable. A detection device scans and detects the submarine cable until the fault location is detected. At this point, the axial reciprocating brushing component moves around the outer circumference of the submarine cable via a surrounding moving component. Simultaneously, the axial reciprocating brushing component moves axially back and forth along the cable, enabling it to perform comprehensive and efficient cleaning of the fault location. This fully exposes the fault location, not only improving the accuracy of fault location identification but also allowing for the creation of markings on the submarine cable. Clear markings distinguish between points on the submarine cable identified by the equipment and those not identified, facilitating subsequent gap work on the salvaged cable. Once the fault location on the cable is fully determined, the adjacent bending limit support mechanism, along with the first support frame and the bending limit support mechanism, extends along the length of the cable via a synchronous telescopic mechanism. After the first support frame and the bending limit support mechanism are fully extended, the height of the bending limit support mechanism is adjusted, extending from the middle first support frame to both sides, gradually lowering the height of the bending limit support mechanism. This effectively limits the bending radius of the cable during the process of hoisting it from the sea to the surface by lifting the first support frame and the bending limit support mechanism, thus achieving a protective effect on the cable.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0022] In some embodiments, please refer to the accompanying drawings. Figures 1-10A submarine cable transportation and inspection device, comprising a first support frame 1; The first support frame 1 has a receiving groove for placing the submarine cable 7. The side of the first support frame 1 is equipped with an all-round brushing and cleaning mechanism 2. The all-round brushing and cleaning mechanism 2 includes a circumferential moving component 21 and an axial reciprocating brushing component 22. The circumferential moving component 21 is installed on the side of the first support frame 1. The axial reciprocating brushing component 22 is installed at the moving end of the circumferential moving component 21. The circumferential moving component 21 is used to drive the axial reciprocating brushing component 22 to move circumferentially along the submarine cable 7. The axial reciprocating brushing component 22 is used to reciprocate brushing the submarine cable 7 radially along the submarine cable 7. Multiple bending limit support mechanisms 3 are installed axially on the left and right sides of the first support frame 1 along the coastal cable 7. Synchronous telescopic mechanisms 4 are installed on the front and rear sides of the first support frame 1 respectively, and the synchronous telescopic mechanisms 4 are connected to all bending limit support mechanisms 3. The first support frame 1 is also fixedly installed with a detection device 5 for detecting whether the submarine cable 7 is faulty.

[0023] In this embodiment, the detection device 5 consists of an underwater camera module, a magnetometer, and a sonar module, enabling the detection device 5 to integrate sound, light, and magnetism to scan and detect the submarine cable 7. During maintenance and repair of submarine cable 7, the equipment of this application is first deployed to the area of ​​submarine cable 7 where abnormal information is detected. The first support frame 1 and the bending limit support mechanism 3 are placed outside the submarine cable 7. Then, the bending limit support mechanism 3 drives the entire equipment to move along the length of the submarine cable. The detection device 5 scans and detects the submarine cable 7 until the detection device 5 detects the fault location of the submarine cable 7. At this time, the axial reciprocating brushing component 22 moves around the outer periphery of the submarine cable 7 through the circumferential moving component 21. At the same time, the axial reciprocating brushing component 22 moves axially back and forth along the submarine cable 7, so that the axial reciprocating brushing component 22 can perform a comprehensive and efficient cleaning operation on the fault location of the submarine cable 7, so that the fault location of the submarine cable 7 can be completely exposed. This not only further improves the accuracy of finding the fault location of the submarine cable 7, but also improves the efficiency of cleaning the submarine cable 7. Clear markings are made on cable 7 to distinguish between points identified by the equipment and those not identified by the equipment, facilitating subsequent intermittent work on the cable 7 after it has been salvaged. Once the fault location of cable 7 is fully determined, the adjacent bending limit support mechanism 3, the first support frame 1, and the bending limit support mechanism 3 are extended along the length of cable 7 via the synchronous telescopic mechanism 4. After the first support frame 1 and the bending limit support mechanism 3 are fully extended, the height of the bending limit support mechanism 3 is adjusted, extending from the middle first support frame 1 to both sides, gradually lowering the height of the bending limit support mechanism 3. This effectively limits the bending radius of cable 7 during the process of hoisting cable 7 from the sea to the surface by lifting the first support frame 1 and the bending limit support mechanism 3, thus achieving a protective effect for cable 7.

[0024] Please see Figure 7 , Figure 8 , Figure 9 and Figure 10 The surrounding moving assembly 21 includes a gear ring 211, a gear 212, a ring moving motor 213, and a ring moving frame 214. The gear ring 211 is rotatably mounted on the side of the first support frame 1 via a limiting assembly. Two ring moving motors 213 are respectively fixedly mounted at the front and rear ends of the first support frame 1. The output end of the ring moving motor 213 is fixedly mounted with a gear 212 that meshes with the gear ring 211. The ring moving frame 214 is fixedly connected to the gear ring 211. In this embodiment, multiple ring shifters 214 are distributed in a circumferential array on the gear ring 211, and each ring shifter 214 is equipped with an axial reciprocating brushing assembly 22. In this embodiment, the limiting component adopts a guide rail slider limiting structure; The axial reciprocating brushing assembly 22 includes a support plate 221, a brushing motor 222, a transmission assembly 223, a drive arm 224, a cleaning brush 225, a pushing assembly, and a reciprocating moving assembly. The support plate 221 is slidably connected to the ring shift frame 214, allowing the support plate 221 to slide axially along the coastal cable 7. The pushing assembly is mounted on the support plate 221, and the moving end of the pushing assembly is rotatably mounted with the drive arm 224. Multiple drive arms 224 are evenly distributed axially along the coastal cable 7. The end of the drive arm 224 away from the pushing assembly is fixedly mounted with the cleaning brush 225. The brushing motor 222 is fixedly mounted on the support plate 221, and the output end of the brushing motor 222 is connected to any drive arm 224 via the transmission assembly 223. Adjacent drive arms 224 are also connected via the transmission assembly 223. The reciprocating moving assembly is mounted on the support plate 221. The transmission assembly 223 adopts a synchronous belt and synchronous pulley transmission structure. The synchronous pulley of the transmission assembly 223 is rotatably connected to the support plate 221 through a bearing, and the synchronous pulley of the transmission assembly 223 is connected to the drive arm 224 through a key, so that the drive arm 224 can rotate synchronously with the synchronous pulley of the transmission assembly 223 and slide along the axial direction of the synchronous pulley. The reciprocating moving assembly includes a rotating disk 228 and a connecting plate 229. The rotating disk 228 is fixedly connected to the output end of the brushing motor 222. One end of the connecting plate 229 is hinged to the eccentric part of the rotating disk 228, and the other end of the connecting plate 229 is hinged to the ring shift frame 214. The axial reciprocating brushing assembly 22 also includes a water spray pipe 2210, a sliding sleeve 2211, and a water pump 2212. The middle part of the water spray pipe 2210 is hinged to the support plate 221. The sliding sleeve 2211 is hinged to the ring shift frame 214. The sliding sleeve 2211 is sleeved on the outside of the tail of the water spray pipe 2210 and slidably connected to the water spray pipe 2210. The water pump 2212 is fixedly connected to the support plate 221, and the water outlet end of the water pump 2212 is connected to the water spray pipe 2210. The pushing component includes a pushing plate 226 and a pushing cylinder 227. The driving arm 224 is rotatably connected to the pushing plate 226 via a bearing. The pushing cylinder 227 is fixedly connected to the support plate 221. The output end of the pushing cylinder 227 is fixedly connected to the pushing plate 226. In this embodiment, a pressure sensor is also installed between the output end of the push cylinder 227 and the push plate 226. The push cylinder 227 is a servo push cylinder. When the push plate 226 is moved by the push cylinder 227 to make the cleaning brush 225 brush the submarine cable 7, the reading of the pressure sensor is kept within the range, so that the cleaning brush 225 can always be in close contact with the side wall of the submarine cable 7, thereby achieving high-quality and high-efficiency cleaning of the submarine cable 7.

[0025] To ensure the safety of the equipment, a protective cover (not shown in the figure) is fixedly installed on the ring shift frame 214. The protective cover protects the transmission assembly 223, drive arm 224, push plate 226, push cylinder 227, rotating disk 228 and connecting plate 229.

[0026] In this invention, the ring-moving motor 213 drives the gear ring 211 to rotate via the gear 212, which in turn drives the ring-moving frame 214 to move around the submarine cable 7. During the movement of the ring-moving frame 214, the brushing motor 222 drives all the drive arms 224 to rotate via the transmission assembly 223, enabling all the cleaning brushes 225 to rotate synchronously. At this time, the pusher cylinder 227 drives the pusher plate 226 to move towards the submarine cable 7, so that the cleaning brushes 225 can closely adhere to the side wall of the submarine cable 7 to perform cleaning operations. The brushing motor 222 also drives the rotating disk 228 to rotate synchronously. The rotating plate 229 causes the support plate 221 to reciprocate linearly on the ring-shifting frame 214, which in turn causes the cleaning brush 225 to continuously move radially back and forth along the submarine cable 7 to perform efficient cleaning operations. During the movement of the support plate 221, the water pump 2212 causes the spray pipe 2210 to continuously spray high-pressure water onto the outer wall of the submarine cable 7, and the sliding sleeve 2211 causes the spray pipe 2210 to swing back and forth, changing the spray angle of the spray pipe 2210 onto the submarine cable 7, thereby achieving an efficient peeling effect on the outer wall of the submarine cable 7.

[0027] Please see Figure 4 , Figure 5 and Figure 6The bending limit support mechanism 3 includes a second support frame 31, a vertical shift support assembly 32, and a support limiting assembly 33. The vertical shift support assembly 32 is installed on the second support frame 31, and the support limiting assembly 33 is installed on the vertical shift support assembly 32.

The vertical shift support assembly 32 includes a vertical shift frame 321, a sliding rod 322, a slider 323, and a locking assembly.

A plurality of sockets 324 are evenly spaced along the length of the slide bar 322. A pin 325 that mates with the sockets 324 is slidably mounted on the slider 323. The vertical moving frame 321 can slide on the slide bar 322 via the slider 323 to change the height of the support limiting component 33, and fix the height of the support limiting component 33 by inserting the pin 325 into the socket 324.

[0028] The support limiting assembly 33 includes a lower support roller 331, a side fixed roller 332, a side movable roller 333, and a one-way moving assembly. The lower support roller 331 is rotatably mounted on the lower end of the vertical moving frame 321, the side fixed roller 332 is rotatably mounted on one side of the vertical moving frame 321, and the one-way moving assembly is mounted on the side of the vertical moving frame 321 away from the side fixed roller 332. The side movable roller 333 is mounted on the one-way moving assembly. In this embodiment, the lower support roller 331, the side fixed roller 332, and the side movable roller 333 are arranged in a triangle. By controlling the side movable roller 333 to move closer to the side fixed roller 332 through the one-way moving component, the lower support roller 331, the side fixed roller 332, and the side movable roller 333 can cooperate to clamp and limit the submarine cable 7. The unidirectional movement assembly includes connecting rods 334, a pull plate 335, and a unidirectional control assembly. The two connecting rods 334 are slidably connected to the vertical moving frame 321. One end of each connecting rod 334 near the side fixed roller 332 is rotatably connected to the side movable roller 333. The other end of each connecting rod 334 is fixedly connected to the pull plate 335. The unidirectional control assembly is installed on the connecting rods 334. The one-way control component includes a slot 336, a locking block 337, a fixing block 338, a pull block 339, and a spring 3310. Multiple slots 336 are evenly spaced along the length of the connecting rod 334. The fixing block 338 is fixedly connected to the vertical moving frame 321, and a locking block 337 that engages with the slot 336 is slidably connected to the fixing block 338. A pull block 339 is fixedly installed on the upper end of the locking block 337. The spring 3310 is sleeved on the outside of the locking block 337, and both ends of the spring 3310 are fixedly connected to the fixing block 338 and the pull block 339, respectively. The vertical moving frame 321 is also equipped with a limit release component, which includes a pull rope 3311 and a winding block 3312. The winding block 3312 is rotatably connected to the vertical moving frame 321. The pull rope 3311 is fixedly installed on the winding block 3312, and both ends of the pull rope 3311 are fixedly connected to the pull blocks 339 of the two unidirectional moving components respectively. In this embodiment, a damping shaft is used between the winding block 3312 and the second support frame 31, so that the winding block 3312 has self-locking property after rotation.

[0029] In this embodiment, drive motors are fixedly installed on the vertical shift frames 321 of the two outermost bending limit support mechanisms 3, and the output end of the drive motors is connected to the lower support rollers 331. By driving the lower support rollers 331 to rotate through the drive motors, the equipment can move along the length of the coastal cable 7. In this invention, after the submarine cable 7 is placed on the lower support roller 331, the pull plate 335 is pulled to move the side movable roller 333 towards the side fixed roller 332. The slot 336 and the locking block 337 cooperate to allow the connecting rod 334 to move only towards the side fixed roller 332. This allows the lower support roller 331, the side fixed roller 332, and the side movable roller 333 to cooperate in clamping and limiting the submarine cable 7. The cooperation of the three can satisfy the limiting and support effect for submarine cables 7 of different diameters. By rotating the winding block 3312 to control the winding of the pull rope 3311, the locking block 337 is disengaged from the slot 336, which can release the restriction effect on the movement of the side movable roller 333 and realize the release of the submarine cable 7.

[0030] The synchronous telescopic mechanism 4 includes a push cylinder 41 and a scissor assembly. The push cylinder 41 is fixedly installed at the lower end of the first support frame 1, and the output end of the push cylinder 41 is fixedly connected to the second support frame 31 adjacent to the first support frame 1. The scissor lift assembly is formed by hinged ends of several scissor lift pieces. Each scissor lift piece includes two scissor lift links 42 and one scissor lift pin 43. The middle parts of the two scissor lift links 42 are hinged through the scissor lift pin 43. Several scissor lift pins 43 are respectively fixedly connected to the first support frame 1 and several corresponding second support frames 31. In this invention, by controlling the second support frame 31 adjacent to the first support frame 1 to move closer to or further away from the first support frame 1 through the push cylinder 41, all the second support frames 31 can be controlled to extend or retract synchronously under the action of the scissor fork, so as to meet the support requirements of the submarine cable 7.
