[0002] A submarine cable, abbreviated as a subsea cable, is a cable laid on the seabed for communication and power transmission. It mainly consists of a conductor, an insulating layer, a sheath, an armor layer, etc., and has the characteristics of low investment, safety and stability, and strong anti-interference ability. It is widely used in fields such as marine communication, island power supply, and offshore wind power.

[0003] When there are damages on the surface of the submarine cable and when multiple submarine cables need to be connected and energized, in order to ensure the normal transmission of electricity and signals, and to facilitate the construction and subsequent maintenance of the submarine cable and enhance the waterproof performance of the submarine cable, it is necessary to connect not only the inside of the submarine cable but also the tape for protective use on the surface of the submarine cable. Therefore, a tape splicing device for submarine cables is required.

[0004] However, there are the following deficiencies in an existing tape splicing device for submarine cables: When a tape splicing device for submarine cables on the current market is used for butt-jointing multiple sections of submarine cables, it is all completed through the cooperation of multiple people, resulting in low efficiency, and it is easy to cause misalignment of the butt-joint surfaces of the two sections of submarine cables due to improper cooperation, reducing the butt-joint area of the submarine cables, lowering the sealing performance of the submarine cables, and increasing the working cost.

[0005] Therefore, we propose a tape splicing device for submarine cables to facilitate the solution of the problems mentioned above. Summary of the Invention

[0006] The purpose of the present invention is to provide a tape splicing device for submarine cables. The two ends of the submarine cable are inserted into the device from the inside of the sliding cover plates on both sides of the device towards the center of the device. A spring telescopic rod is rotatably connected to the outer top of the other end of the sliding cover plate. The spring telescopic rod rotates with the sliding cover plate through a rotating bead. The submarine cable passing through the sliding cover plate continues to be pushed inward until it contacts the anti-slip wheel. At this time, the first motor is started. The first motor drives the spur gear to rotate through the first spur gear. While the spur gear is rotating, it drives the convex gear disk to rotate. At the same time, the turntable fixed between the spur gear and the convex gear disk rotates in a plurality of fixed chutes. At this time, the convex gear disk drives a plurality of bevel gears to rotate. The bevel gears are fixed to the worm through a rotating rod. Therefore, the worm rotates accordingly.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. When the present invention conducts submarine cable docking, the two ends of the submarine cable are inserted from the funnel-shaped sliding cover plates on both sides of the device. The funnel shape can automatically guide the submarine cable, reducing the alignment time. The rotating rods on the outer sides of the sliding cover plates cooperate with the sleeve rods, enabling them to move outward to adapt to different specifications of submarine cables. The spring telescopic rods at the outer top of the other end are connected through rotating shaft balls, ensuring the stable movement of the sliding cover plates and their reset after work.

Moreover, the anti-slip wheels on both sides can rotate independently, avoiding the misalignment of the docking surface due to different lengths of the submarine cable, thus avoiding the problem of misalignment of the docking surfaces of the two submarine cables caused by manual operation and improper cooperation of multiple people, reducing the docking area of the submarine cable, reducing the sealing performance of the submarine cable, and increasing the working cost.

[0018] 2. After the submarine cables on both sides reach the anti-slip wheels, the present invention's device starts the second electric telescopic rod to move the guiding cylinder plate to clamp the submarine cable, making the interface angles consistent. At the same time, the first electric telescopic rod and the third electric telescopic rod are started, driving the first docking plate, the second docking plate and the heating coil to move and form a ring.

Using the cooperation of the arc groove and the slide bar, the blades on the heating coil trim the cross-section of the submarine cable until it is smooth and flat. Then the heating coil is turned on to melt the cross-section of the submarine cable. After withdrawing the docking plate, the first motor drives the anti-slip wheels to push the submarine cables to dock. The rotating beads in the guiding cylinder plate assist the movement of the submarine cable to ensure the coincidence accuracy. Finally, the docking plate is driven by the electric telescopic rod again to clamp the submarine cable, squeezing the protruding joint part. The second motor is started as needed to rotate the docking plate to enhance the flatness and sealing performance of the fusion part, thereby realizing the splicing of the submarine cable and improving the working efficiency.

Specific implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Example 1, according to Figures 1 - 3As shown in the figure, a tape splicing device for submarine cables includes a base 1, a feeding mechanism 2, and a hot melt splicing mechanism 3. The feeding mechanism 2 is arranged on the top of the base 1, and the hot melt splicing mechanism 3 is arranged inside the feeding mechanism 2. The feeding mechanism 2; The feeding mechanism 2 includes a plurality of anti-slip wheels 210 and a plurality of sliding cover plates 216. The two submarine cable lines to be spliced are accurately guided to the inner working range of the plurality of anti-slip wheels 210 through the plurality of sliding cover plates 216 on both sides. Then, through the synchronous rotation of the plurality of anti-slip wheels 210, the joints of the two submarine cable lines to be spliced are automatically and accurately butted. Moreover, during the entire butting process, the position and angle of the submarine cable lines can be guaranteed to be stable. Among them, the plurality of sliding cover plates 216 can be spliced into a funnel-shaped sliding hopper, increasing the error tolerance rate when inserting the submarine cable lines and improving the work efficiency. The hot melt splicing mechanism 3; The hot melt splicing mechanism 3 includes a guiding cylinder plate 306, a rotating bead 307, and a blade 316. By the rotation of the rotating bead 307 in the guiding cylinder plate 306, it can ensure that after the submarine cable lines are butted on both sides of the guiding cylinder plate 306, the submarine cable lines can still slide stably and accurately, improving the accuracy and stability for the subsequent hot melt splicing work.

A rotating rod 208 is rotatably connected to the inner side of the plurality of fixed rods 207. A worm 212 is fixedly connected to the inner end of the rotating rod 208. A bevel gear 209 is fixedly connected to the other end of the rotating rod 208. A plurality of anti-slip wheels 210 are rotatably connected to the inner side of the plurality of fixed rods 207. A turbine 211 is fixedly connected to the outer side of the plurality of anti-slip wheels 210. The turbine 211 meshes with the worm 212. The surface of the anti-slip wheel 210 is a concave arc surface. A plurality of anti-slip rubber strips are regularly arranged and fixed on the surface of the anti-slip wheel 210, and the number of anti-slip wheels 210 is four.

[0024] The effects achieved by the entire Example 1 are as follows: When docking submarine cables, the two ends of the submarine cables are inserted into the sliding cover plates 216 on both sides of the device. The sliding cover plates 216 are combined into a funnel shape, which can guide the submarine cables into the device, reducing the alignment time. The rotating rods 215 are fixed on the outer sides of the sliding cover plates 216. The rotating rods 215 cooperate with the sleeve rods 214 to enable them to move outwards, adapting to different specifications of submarine cables. The top of the outer side of the other end of the sliding cover plate 216 is connected to the spring telescopic rod 213, which rotates through the rotating shaft ball to prevent the sliding cover plate 216 from automatically shifting and can be reset after work. Moreover, the friction between the sliding cover plate 216 and the submarine cable has a cleaning effect. The submarine cable is pushed inwards through the sliding cover plate 216 to the anti-slip wheels 210. At this time, the first motor 217 is started, and the first motor 217 drives the straight tooth disc 205 to rotate through the first straight gear 218.

[0025] Example 2, according to Figures 2 - 4 As shown, a first motor 217 is fixedly connected to the top of the base 1. The output end of the first motor 217 is fixedly connected to a first straight gear 218. The straight gear meshes with the straight tooth disc 205. The spring telescopic rods 213 are fixedly connected to the inner sides of multiple fixing rods 207. The bottom of the spring telescopic rod 213 is rotatably connected to the sliding cover plate 216. The rotating rods 215 are arranged on the outer sides of the spring telescopic rods 213. The rotating rods 215 are connected to the sliding cover plate 216. The outer sides of the rotating rods 215 are rotatably connected to the sleeve rods 214. The other side of the sleeve rod 214 is fixedly connected to the fixing rod 207. The sleeve rod 214 is a rotating cylinder with an inner diameter slightly larger than the diameter of the rotating rod 215. A connecting rod is fixed on its outer side and fixedly connected to the fixing rod 207. The inner end of the spring telescopic rod 213 is fixed with a rotating shaft ball, which is rotatably connected to the ball shaft chamber opened on the outer side surface of the sliding cover plate 216 through the rotating shaft ball. The effects achieved by the entire Example 2 are as follows: The rotation of the straight tooth disc 205 drives the convex tooth disc 204 to rotate. The turntable 203 fixed between the straight tooth disc 205 and the convex tooth disc 204 rotates in multiple fixed sliding grooves 202. The fixed sliding grooves 202 in four directions ensure the stable rotation of the turntable 203. The convex tooth disc 204 drives multiple bevel gears 209 to rotate. The bevel gears 209 are fixed to the worm 212 through the rotating rods 208, and the worm 212 rotates accordingly. The fixing rods 207 ensure the stable rotation of the worm 212. The worm 212 meshes with the turbine 211, driving the turbine 211 to rotate. The turbine 211 drives the anti-slip wheels 210 to rotate. When multiple anti-slip wheels 210 rotate, they clamp the submarine cable and drive it to move towards the interior of the device. The surface of the anti-slip wheels 210 is concave, increasing the contact surface with the submarine cable. The surface rubber anti-slip strips increase the clamping stability of the submarine cable and protect the surface of the submarine cable. The two anti-slip wheels 210 on both sides can rotate separately, avoiding the situation where the docking surface shifts due to inconsistent lengths of the submarine cables.

[0026] Example 3, according to Figures 5 - 8As shown in the figure, the hot melt connection mechanism 3 further includes a first electric telescopic rod 301. The first electric telescopic rod 301 is fixedly connected to the top of the base 1. The other end of the first electric telescopic rod 301 is fixedly connected to a motor bracket 320. A second motor 302 is fixedly connected to the inner side of the motor bracket 320. The output end of the second motor 302 is fixedly connected to a second spur gear 303. A plurality of fixing plates 304 are fixedly connected to the inner sides of the plurality of fixing beams 206. A second electric telescopic rod 305 is fixedly connected to the inner sides of the plurality of fixing plates 304. The inner end of the second electric telescopic rod 305 is fixedly connected to a guiding cylinder plate 306. A top reinforcement plate 308 is fixedly connected to the top of the fixing beam 206. The guiding cylinder plate 306 is rotationally connected to a rotating bead 307. A first docking plate 313 is arranged inside the guiding cylinder plate 306. A second docking plate 318 is arranged at the bottom of the first docking plate 313. A plurality of tooth blocks 317 are fixedly arranged on the outer sides of the first docking plate 313 and the second docking plate 318 in a regular arrangement. Arc-shaped sliding grooves are formed inside the first docking plate 313 and the second docking plate 318. A first arc-shaped sliding bar 311 and a second arc-shaped sliding bar 312 are respectively slidably connected in the arc-shaped sliding grooves inside the first docking plate 313 and the second docking plate 318. The top of the first arc-shaped sliding bar 311 is fixedly connected to a top bracket 310. The top of the top bracket 310 is fixedly connected to a third electric telescopic rod 309. The other end of the third electric telescopic rod 309 is fixedly connected to the top reinforcement plate 308. The second arc-shaped sliding bar 312 is fixedly connected to the top of the motor bracket 320. First heating coils 314 are fixedly connected to both sides of the first docking plate 313. Blades 316 are fixedly connected to the outer sides of the two first heating coils 314. A sliding card slot is formed inside the first heating coil 314. A sliding heat conducting block 315 is slidably connected to the inside of the sliding card slot. The inside of the sliding heat conducting block 315 is fixedly connected to the inside of the sliding card slot through a plurality of compression springs. Two second heating coils 319 are fixedly connected to both sides of the second docking plate 318. The plurality of tooth blocks 317 are meshed with the second spur gear 303. The first docking plate 313 and the second docking plate 318 can be clamped together to form a complete cylindrical rotating cylinder. The vertical section of the arc-shaped sliding groove is an arc-shaped "soil" groove. The vertical sections of the first arc-shaped sliding bar 311 and the second arc-shaped sliding bar 312 are arc-shaped "soil" rings, and the vertical section sizes of the first arc-shaped sliding bar 311 and the second arc-shaped sliding bar 312 are slightly smaller than the vertical section size of the arc-shaped sliding groove.

[0027] The effect achieved by the entire Embodiment 3 is as follows: The first docking plate 313 and the second docking plate 318 rotate, driving the blades 316 of the first heating coil 314 and the second heating coil 319 on both sides to rotate, trimming the cross-section of the submarine cable. After trimming to be flat, the first heating coil 314 and the second heating coil 319 are turned on to heat the cross-section of the submarine cable until it melts. Then, the first electric telescopic rod 301 and the second electric telescopic rod 305 are activated to retract the docking plates. Next, the first motor 217 is started, and the preliminarily melted submarine cable is driven to move towards the middle through the anti-slip wheels 210. The rotating beads 307 in the guiding cylinder plate 306 assist the movement of the submarine cable, improving the coincidence accuracy of the cross-section, so that the cross-sections of the submarine cable come into contact and coincide to complete the connection. Then, the first electric telescopic rod 301 and the third electric telescopic rod 309 are started to drive the docking plates to clamp the submarine cable again, squeezing the protruding part generated by melting and docking. The second motor 302 is started as needed to rotate the docking plates, enhancing the flatness and sealing performance of the fusion part.

[0028] The working principle of the entire device is as follows: When it is necessary to start docking the submarine cable, first insert the submarine cables at both ends into the device center from inside the sliding cover plates 216 on both sides of this device. Since the shape formed by multiple sliding cover plates 216 is a funnel shape, the submarine cables can be directly inserted. When the angle is incorrect, they will be correctly guided into the device by the funnel-shaped sliding cover plates 216. Therefore, there is no need to spend too much time aligning the channels. Moreover, rotating rods 215 are fixed on the outer sides of multiple sliding cover plates 216. Through the rotation between the rotating rods 215 and the sleeve rods 214, the sliding cover plates 216 can move outward, thereby accommodating submarine cables of more specifications. In order to make the sliding cover plates 216 move more stably, a spring telescopic rod 213 is rotatably connected to the top of the outer side of the other end of the sliding cover plate 216. The spring telescopic rod 213 rotates with the sliding cover plate 216 through a rotating shaft ball, so that the sliding cover plate 216 will not move automatically, and the position of the sliding cover plate 216 can be restored automatically when the work is completed. During this period, one end of the sliding cover plate 216 is always in frictional contact with the submarine cable, playing a certain cleaning role. The submarine cable passing through the sliding cover plate 216 is continuously pushed inward until it contacts the anti-slip wheels 210. At this time, start the first motor 217. The first motor 217 drives the straight tooth disc 205 to rotate through the first straight gear 218. While the straight tooth disc 205 is rotating, it drives the convex tooth disc 204 to rotate. At the same time, the turntable 203 fixed between the straight tooth disc 205 and the convex tooth disc 204 rotates in multiple fixed sliding grooves 202. The fixed sliding grooves 202 in four directions ensure the stable rotation of the turntable 203. At this time, the convex tooth disc 204 drives multiple bevel gears 209 to rotate. The bevel gears 209 are fixed to the worm 212 through the rotating rods 208. Therefore, the worm 212 rotates accordingly. The fixed rod 207 ensures the stability of the rotation of the worm 212. Since the worm 212 meshes with the worm wheel 211, the worm wheel 211 is driven to rotate and drives the anti-slip wheels 210 to rotate. At this time, when multiple anti-slip wheels 210 rotate together, they clamp the submarine cable inside the anti-slip wheels 210 and drive it to move into the device. The anti-slip wheels 210 with a concave surface increase the contact surface with the submarine cable, and the rubber anti-slip strips on its surface increase the clamping stability of the submarine cable and at the same time protect the surface of the submarine cable. The anti-slip wheels 210 on both sides can rotate separately to prevent the docking surface of the submarine cable from shifting due to inconsistent lengths of the placed submarine cables when the anti-slip wheels 210 on both sides rotate together.

[0029] When the submarine cables on both sides are moved to their combined positions through the anti-slip wheels 210, the second electric telescopic rod 305 is activated to move the guiding cylinder plates 306 on both sides towards the middle of the device until the guiding cylinder plates 306 on both sides face each other and clamp the submarine cables in contact. At this time, the angles of the cable docking interfaces on both sides are the same. Then, the first electric telescopic rod 301 and the third electric telescopic rod 309 are simultaneously activated to move the first docking plate 313 and the second docking plate 318 towards the inner side of the device. While the first docking plate 313 and the second docking plate 318 are moving inwards, they drive the first heating coil 314 and the second heating coil 319 to move synchronously until the first heating coil 314 and the second heating coil 319 come into contact with each other and form a complete annular heating coil. At this time, the first motor 217 of the feeding mechanism 2 is activated again to drive the submarine cables on both sides further towards the inner side of the device until the cable cross-sections are in contact with the combined heating coils on both sides. Then, the second motor 302 is activated to drive the second spur gear 303 to rotate. The second spur gear 303 drives the first docking plate 313 and the second docking plate 318 to rotate through the tooth blocks 317. Thus, the first docking plate 313 and the second docking plate 318 rotate through the sliding between the arc-shaped sliding grooves formed on them and the first arc-shaped sliding bar 311 and the second arc-shaped sliding bar 312. While the first docking plate 313 and the second docking plate 318 are rotating, they drive the blades 316 on the first heating coils 314 and the second heating coils 319 on both sides to rotate, thereby trimming the cross-sections of the submarine cables on both sides until the cross-sections of the submarine cables on both sides are flat and smooth. Then, the first heating coil 314 and the second heating coil 319 are directly activated to heat the cable cross-sections in contact with them until the cross-sections of the submarine cables on both sides are melted. At this time, the first electric telescopic rod 301 and the second electric telescopic rod 305 are activated respectively to retract the first docking plate 313 and the second docking plate 318 towards the outer side of the device. Then, the first motor 217 is activated again to drive the anti-slip wheels 210 to move the submarine cables on both sides with their cross-sections initially melted and heated towards the middle. During this period, the guiding cylinder plates 306 can accurately guide the submarine cables through the rotating beads 307 inside them and can also move the submarine cables inside them, thereby increasing the accuracy of the cross-section overlapping and connection of the submarine cables on both sides. At this time, the cross-sections of the submarine cables on both sides are in contact and overlap, achieving the connection work. To ensure the sealing and flatness of the connection surface, the first electric telescopic rod 301 and the third electric telescopic rod 309 are activated again to drive the first docking plate 313 and the second docking plate 318 to clamp the submarine cables again. At this time, the protruding connection parts that appear on the melted and squeezed cable cross-sections are squeezed inwards. Then, the second motor 302 is activated as needed to drive the first docking plate 313 and the second docking plate 318 to rotate, increasing the flatness and sealing of the cable cross-sections that are being fused.
