Description

Corrugated copper submarine cable and submarine cable production equipment Technical Field

[0001] The invention belongs to the technical field of corrugated copper submarine cable production, in particular to a corrugated copper submarine cable and submarine cable production equipment. Background Art

[0002] Corrugated copper submarine cables are primarily used in marine environments as a medium for transmitting power and signals. They are characterized by their resistance to corrosion and damage from the marine environment, ensuring stable transmission of power and signals. These cables are available in various specifications and designs to meet diverse power and signal transmission needs. Their structure includes a core conductor, insulation layer, corrugated copper shield, and protective sheath.

[0003] In the existing technology for producing corrugated copper submarine cables, copper foil or copper wire is first wound around the circumference of the submarine cable using a winding machine, and then a technician performs corrugated copper processing on the wound submarine cable through manual argon arc welding, thereby forming a layer of wrinkled texture on the circumference of the submarine cable. This texture not only improves the strength and hardness of the material, but also enhances its corrosion resistance and conductivity.

[0004] There are still some problems in the actual application of the above scheme. During the process of argon arc welding performed by technicians, argon arc welding will generate strong arc light and a large amount of heat energy, which may have adverse effects on the health of the operators. In addition, when welding is performed by a large number of technicians, the welding speed is relatively slow and the efficiency is low, which will make the production efficiency of corrugated copper submarine cables low.

[0051] Example 2

[0052] 1 to 10 , comparative example 1, another embodiment of the present invention is as follows:

[0053] 1 and 2, a corrugated copper submarine cable production device according to an embodiment of the present invention includes a workbench 1, and also includes a fixed warehouse 2 arranged in the middle of the upper surface of the workbench 1, a fixed tube 51 is passed through the interior of the fixed warehouse 2, and a winding assembly is provided on the circumferential surface of one end of the fixed tube 51. The winding assembly includes a rotating ring 5 rotatably arranged on the circumferential surface of the fixed tube 51, and the rotating ring 5 is driven to rotate by a motor provided inside the fixed warehouse 2; two connecting shafts 52 fixed to the circumferential surface of the rotating ring 5, and each connecting shaft 52 is rotatably connected to the winding assembly at one end away from the rotating ring 5. A winding drum 54, on which a large amount of copper foil or copper wire is wound; and a welding bin 3 arranged on one side of the fixed bin 2, wherein a welding assembly is arranged in the welding bin 3, and the welding assembly includes two support frames 34, the top ends of the two support frames 34 are fixedly connected to limit rings 37, and a positioning ring 35 is rotatably arranged between the two limit rings 37, and the inner wall of the positioning ring 35 is fixedly connected to a plurality of arc welding heads 36, and the plurality of arc welding heads 36 are distributed in a circular array along the inner wall of the positioning ring 35, and are used to perform argon arc welding on the submarine cable 6 wrapped with copper foil or copper wire, thereby forming a wrinkle texture.

[0054] Specifically, when adding corrugated copper shielding wire to the twisted submarine cable 6, the submarine cable 6 will first be moved by the traction of the traction machine, and the traction machine will drive the submarine cable 6 to rotate. The traction machine is an existing traction device. One end of the stranded submarine cable 6 is fixed to the traction machine, and the traction machine can drive the submarine cable 6 to move. Then the winding assembly can wind the copper foil or copper wire on the circumferential surface of the submarine cable 6, and continuously wind the copper foil or copper wire on the circumferential surface of the moving submarine cable 6. After the winding is completed, the submarine cable 6 will enter the welding chamber 3, and a positioning ring 35 is provided for rotation in the welding chamber 3. There are several arc welding heads 36 distributed in a circular array on the inner wall of the positioning ring 35. The arc welding heads 36 are in contact with the circumferential surface of the sea blue, so that the copper foil or copper wire can be wrinkled. The processing of the wrinkle texture can greatly improve the strength and corrosion resistance of the copper layer, thereby better protecting the internal submarine cable 6, and saving a large number of technicians from slowly performing argon arc welding on the submarine cable 6. The setting of the welding chamber only requires technicians to repair the welding defects. The welding chamber 3 indirectly protects the health of the technicians, because long-term argon arc welding will affect people's health.

[0055] As shown in Figure 2, the connecting shaft 52 of the present invention is threadedly connected to a screw 55 at one end away from the rotating ring 5, and the circumferential surface of the screw 55 is fixedly connected to a retaining ring 56, and the circumferential surface of the connecting shaft 52 is fixedly connected to a first disc 53, and the winding disc 54 is rotatably arranged between the retaining ring 56 and the first disc 53 for limiting the winding disc 54.

[0056] Specifically, when producing and processing the submarine cable 6, it is first necessary to place the winding disk 54 with copper foil or copper wire between the clamping ring 56 and the first disc 53. First, turn out the screw 55, and then put the winding sleeve on the connecting shaft 52. The winding disk 54 will now be placed on the first disc 53, and then the screw 55 and the connecting shaft 52 are threaded together. When the screw 55 is tightened to the tightest, the winding disk 54 is also set between the clamping ring 56 and the first disc 53. The clamping ring 56 will not exert an extrusion force on the winding disk 54. In this way, the winding disk 54 can be rotated and set on the connecting shaft 52, which is convenient for winding the copper foil or copper wire.

[0057] 3 and 4 , two support columns 7 are provided between the fixing bin 2 and the welding bin 3 of the present invention. The two support columns 7 are symmetrically arranged on both sides of the submarine cable 6. Each support column 7 is fixedly connected to the workbench 1. The top of the support column 7 is fixedly connected to an electric push rod 71. The output end of the electric push rod 71 is fixedly connected to a limiting semi-ring 72, which is used to assist in the winding of copper foil or copper wire, and to clamp the copper foil or copper wire so that the winding does not deviate.

[0058] Specifically, when the winding assembly winds the copper foil or copper wire onto the submarine cable 6, two support columns 7 are set between the fixing chamber 2 and the welding chamber 3. The two support columns 7 are symmetrically arranged on both sides of the submarine cable 6. During the winding process of the copper foil or copper wire, the electric push rods 71 ​​at the top of the two support columns 7 will push the limiting semi-rings 72 fixed to their output ends to move to a position close to the submarine cable 6. The circular ring formed by the two limiting semi-rings 72 is smaller than the diameter of the submarine cable 6. The two limiting semi-rings 72 can play a role in combing and correcting the copper foil when the copper foil or copper wire is wound. Because the copper foil is in a tape-like style and is easy to deflect, the limiting semi-rings 72 assist the winding assembly in winding, thereby improving the winding efficiency and quality.

[0059] As shown in Figure 3, the welding assembly of the present invention also includes a base 31 arranged inside the welding bin 3. Two first motors 32 are fixedly connected to the upper surface of the base 31. The output end of each first motor 32 is fixedly connected to a cam 33. The circumferential surface of the positioning ring 35 is fixedly connected with a first gear tooth 310 adapted to the cam 33. The cam 33 is used to drive the positioning ring 35 to rotate reciprocatingly.

[0060] Specifically, after the winding machine wraps the copper foil or copper wire around the submarine cable 6, the submarine cable 6 enters the welding chamber 3 under the traction of the traction machine, and the two first motors 32 are started to drive the cam 33 fixed to the output end thereof. The cam 33 engages with the first gear 310 fixed to the circumferential surface of the positioning ring 35. The rotation of the cam 33 drives the positioning ring 35 to continue to rotate back and forth, and then the several arc welding heads 36 on the inner wall of the positioning ring 35 weld the copper foil or copper wire on the circumferential surface of the submarine cable 6 to form a wrinkle texture. During the reciprocating rotation process, the submarine cable 6 rotates to a certain extent, so that the wrinkle copper texture formed on the circumferential surface of the submarine cable 6 has a certain periodicity, which increases the strength of the wrinkle copper to a certain extent and enhances the protection of the submarine cable 6.

[0061] 6 and 7 , a plurality of guide posts 39 are fixedly connected to both sides of the positioning ring 35 of the present invention. A first groove 38 is provided at the position of each limiting ring 37 corresponding to the guide post 39. The rotation of the positioning ring 35 drives the guide post 39 to slide in the first groove 38. A plurality of air outlet holes 351 are provided at one end of each arc welding head 36 in the positioning ring 35 close to the submarine cable 6. The air outlet holes 351 are used to spray rare gas argon to prevent copper oxidation during arc welding.

[0062] Specifically, when the positioning ring 35 is driven to rotate by the cam 33, a first groove 38 is opened on the side where the two limit rings 37 are close to each other, and then a plurality of guide columns 39 fixed to the circumferential surface of the positioning ring 35 will slide in the first groove 38, so that the positioning ring 35 can rotate between the two limit rings 37, and at the same time support the positioning ring 35 so that it can be erected between the two limit rings 37. When the arc welding head 36 in the positioning ring 35 performs argon arc welding on the submarine cable 6, a plurality of air outlet holes 351 are opened on the circumferential surface of the arc welding head 36 close to the end of the submarine cable 6. The air outlet holes 351 are used to spray rare gas argon, thereby protecting the molten copper from oxidation with the air when arc welding is performed on the copper foil or copper wire.

[0063] 6 , a plurality of fixed blocks 311 are fixedly connected to one side of a limiting ring 37 of the present invention near the outlet of the welding chamber 3. Each fixed block 311 is inclined at a certain angle toward the submarine cable 6. A second motor 312 is fixedly connected to the upper surface of each fixed block 311. A fan body 313 is fixedly connected to the output end of each second motor 312 for cooling the submarine cable 6 after arc welding.

[0064] Specifically, after the welding of the corrugated copper shielding layer of the submarine cable 6 is completed in the welding chamber 3, the limit ring 37 is pulled out, and the limit ring 37 close to the outlet of the welding chamber 3 is fixedly connected to a plurality of second motors 312 on its side close to the outlet of the welding chamber 3. The second motor 312 is fixedly connected to the upper surface of the inclined fixed block 311. The inclination of the fixed block 311 is to enable the second motor to face the submarine cable 6, so that the submarine cable 6 after arc welding can be physically cooled. Because the corrugated copper after arc welding has a high temperature, cooling it directly by spraying water will affect the hardness of the corrugated copper and the quality of the submarine cable 6. If cooling is not performed, the winding equipment may be damaged during the winding process, so the submarine cable 6 after arc welding is processed by physical cooling.

[0065] 5 to 9 , in this embodiment, a cleaning assembly is provided on one side of another limit ring 37 close to the fixed bin 2, and the cleaning assembly includes a fixed plate 8 fixedly connected to the side of the limit ring 37; a hydraulic cylinder 81 rotatably connected to the surface of the fixed plate 8; a guide block 82 fixedly connected to the output end of the hydraulic cylinder 81, and a groove block 89 is provided at the position of the limit ring 37 corresponding to the guide block 82, and the guide block 82 slides in the groove block 89; two positioning blocks 85 fixedly connected to the side of the limit ring 37, each positioning block 85 is rotatably connected to an adjusting rod 86, and the two adjusting rods 86 are fixedly connected to the same guide plate 88, and one end of the guide plate 88 is fixedly connected to the limit block 83, and a cleaning wheel 84 is rotatably provided inside the limit block 83. The cleaning wheel 84 is used to clean oil stains and the like on the cable after the copper wire is wrapped, so as to prevent other chemical reactions from occurring during argon arc welding and affecting the strength of the wrinkled copper.

[0066] Specifically, a cleaning assembly is provided on one side of the limit ring 37 close to the fixing bin to prevent the copper foil or copper wire from being contaminated with oil stains or other dirt during storage, which may affect the arc welding effect of the copper foil or copper wire during welding. When the wound submarine cable 6 is pulled to the position of the cleaning assembly, the hydraulic cylinder 81 is started at this time. The hydraulic cylinder 81 will drive the guide block 82 fixed to its output end, so that the guide block 82 squeezes the guide plate 88 out of the groove block 89, and then the guide plate 88 can be rotated under the limit of the positioning block 85 through the adjusting rods 86 fixed on both sides, and the guide plate 88 drives the limit block fixed on the side to move. The movement of the limit block 83 enables the cleaning wheel 84 to abut against the submarine cable 6. The cleaning wheel 84 mainly cleans the copper foil or copper wire wrapped around the submarine cable 6 through the sponge layer adhered to its circumferential surface.

[0067] 9 , the two adjusting rods 86 of the present invention are rotatably connected to the limiting wheel 87 at one end away from the guide plate 88. After the cleaning wheel 84 abuts against the submarine cable 6, the limiting wheel 87 will also abut against the submarine cable 6 to limit the submarine cable 6, thereby preventing the submarine cable 6 from shaking during arc welding.

[0068] Specifically, when the cleaning wheel 84 abuts against the submarine cable 6, the adjusting rods 86 rotating on both sides of the guide plate 88 will also rotate, and the limiting wheel 87 arranged at one end of the adjusting rod 86 will abut against the submarine cable 6, thereby clamping and fixing the submarine cable 6, so that the submarine cable 6 keeps moving concentrically and prevents it from shaking, which affects the welding effect in the welding groove.

[0069] 1 and 5 , a support plate 4 is fixedly connected to one end of the workbench 1 of the present invention, a positioning assembly is fixedly connected to the middle of the support plate 4, and the positioning assembly includes a positioning tube 41 that rotates through the middle of the support plate 4; a fixing ring 42 is fixed to one side of the positioning tube 41, and a plurality of positioning frames 44 are rotatably provided between the positioning tube 41 and the fixing ring 42;

[0070] Several positioning shafts 43 that rotate through the fixing ring 42, the positioning shafts 43 pass through the fixing ring 42 and are rotatably connected to the positioning frame 44, and the positioning shafts 43 are used to limit the positioning frame 44; a connecting rod 45 is slidably connected in each positioning frame 44, and a plurality of fixing rods 410 are fixed to the surface of the support plate 4, and the fixing rods 410 and the connecting rods 45 are rotatably connected. The number of the fixing rods 410 and the connecting rods 45 corresponds to that of the fixing rods 410, and each connecting rod 45 is rotatably connected to a universal ball 49 at one end close to each other. The universal ball 49 is used for the transmission and clamping of the submarine cable 6, and has the effect of concentric positioning of the transmission of the submarine cable 6, and the universal ball 49 will not hinder the transmission of the submarine cable 6, which is convenient for subsequent winding work.

[0071] Specifically, when the submarine cable 6 is transmitted through the support plate 4, in order to better concentrically position the submarine cable 6 and prevent it from deflecting, the positioning tube 41 is first rotated. The rotation of the positioning tube 41 can drive the positioning frame 44 rotatably arranged between the positioning tube 41 and the fixing ring 42 to rotate, and the positioning tube 41 itself is rotatably arranged between the positioning tube 41 and the fixing ring 42, but because the connecting rod 45 is rotatably connected to the fixing rod 410, the fixing rod 410 is fixed to the surface of the support plate 4, so that the connecting rod 45 can only slide and rotate in the fixing frame. Therefore, after rotating the positioning tube 41, the connecting rod 45 can be adjusted to rotate in the positioning tube 41 and the fixing ring 42, and then the submarine cable 6 is limited, but it will not be clamped, because the end of the connecting rod 45 close to each other is rotatably provided with a universal ball 49, and the universal ball 49 can not affect the transportation of the submarine cable 6 when a large clamping force is applied to the submarine cable 6, and can also achieve the concentric clamping and limiting of the submarine cable 6.

[0072] 5, the circumferential surface of the positioning tube 41 of the present invention is fixed with a plurality of second gear teeth 46, and a first gear 47 meshing with the second gear teeth 46 is rotatably provided in the fixing plate 8. A rotating handle 48 is fixed to one side of the first gear 47. The rotating handle 48 passes through one side of the support plate 4 and is fixed to the first gear 47 inside. It is used to control the rotation of the positioning tube 41 and directly rotate the positioning tube 41. After clamping the submarine cable 6, the positioning tube 41 cannot be effectively fixed, which will affect the limiting effect. Therefore, by rotating the handle 48 , the first gear 47 and the second gear teeth 46. Turning the handle 48 will drive the first gear 47. The first gear 47 is rotatably arranged in the internal cavity of the support plate 4. The rotation of the first gear 47 can drive the second gear teeth 46 engaged therewith. The second gear teeth 46 are fixed to the circumferential surface of the positioning tube 41, and the positioning tube 41 can rotate within the support plate 4, so it can drive the positioning tube 41 to rotate, and through the meshing and clamping of the first gear 47 and the second gear teeth 46, the limit of the submarine cable 6 can be adjusted more stably.

[0073] Working principle: when adding corrugated copper shielding wire to the twisted submarine cable 6, the submarine cable 6 will first be moved by the traction of the traction machine, and the traction machine will drive the submarine cable 6 to rotate. The traction machine is an existing traction device. One end of the stranded submarine cable 6 is fixed to the traction machine, and the traction machine can drive the submarine cable 6 to move. Then the winding assembly can wind copper foil or copper wire on the circumferential surface of the submarine cable 6. First, the winding disk 54 with copper foil or copper wire needs to be placed between the clamping ring 56 and the first disc 53. Before winding, first turn out the screw 55, and then put the winding sleeve on the connecting shaft 52. The winding disk 54 will be placed on the first disc 53 at this time, and then the screw 55 is threaded together with the connecting shaft 52. When the screw 55 is tightened to the tightest, the winding disk 54 is also set between the clamping ring 56 and the first disc 53, and the clamping ring 56 will not exert force on the winding disk 54 The extrusion pressure can make the winding drum 54 rotate on the connecting shaft 52, which is convenient for the winding of copper foil or copper wire, and then continuously wind the copper foil or copper wire around the circumferential surface of the submarine cable 6. After winding, the submarine cable 6 will enter the welding chamber 3. A positioning ring 35 is arranged to rotate in the welding chamber 3. A plurality of arc welding heads 36 are distributed in a circumferential array on the inner wall of the positioning ring 35. The arc welding heads 36 abut against the circumferential surface of the submarine cable, so that the copper foil or copper wire can be wrinkled. The processing of the wrinkle texture can greatly improve the strength and corrosion resistance of the copper layer, thereby better protecting the internal submarine cable 6 and saving a large number of technicians from slowly performing argon arc welding on the submarine cable 6. The setting of the welding storage only requires technicians to repair the welding defects. The welding chamber 3 indirectly protects the health of the technicians, because long-term argon arc welding will affect people's health.

[0074] After the winding machine wraps the copper foil or copper wire around the submarine cable 6, the submarine cable 6 enters the welding chamber 3 under the traction of the traction machine, and the two first motors 32 are started to drive the cam 33 fixed to the output end thereof. The cam 33 is engaged with the first gear 310 fixed to the circumferential surface of the positioning ring 35. The rotation of the cam 33 drives the positioning ring 35 to continue to rotate back and forth, and then the several arc welding heads 36 on the inner wall of the positioning ring 35 are welded to the copper foil or copper wire on the circumferential surface of the submarine cable 6 to produce a wrinkle texture. During the reciprocating rotation process, the submarine cable 6 rotates to a certain extent, so that the wrinkle copper texture formed on the circumferential surface of the submarine cable 6 has a certain periodicity, which increases the strength of the wrinkle copper to a certain extent and enhances the protection of the submarine cable 6. At the same time, the limit ring 37 near the fixing chamber is welded. A cleaning assembly is provided on one side to prevent the copper foil or copper wire from being contaminated with oil or other dirt during storage, which may affect the arc welding effect of the copper foil or copper wire during welding. When the wound submarine cable 6 is pulled to the position of the cleaning assembly, the hydraulic cylinder 81 is started at this time. The hydraulic cylinder 81 will drive the guide block 82 fixed to its output end, so that the guide block 82 squeezes the guide plate 88 out of the groove block 89, and then the guide plate 88 can be rotated under the limit of the positioning block 85 through the adjusting rods 86 fixed on both sides, and the guide plate 88 drives the limit block fixed on the side to move. The movement of the limit block 83 enables the cleaning wheel 84 to abut against the submarine cable 6. The cleaning wheel 84 mainly cleans the copper foil or copper wire wrapped around the submarine cable 6 through the sponge layer adhered to its circumferential surface.

[0075] Finally, after the submarine cable 6 completes the welding of the corrugated copper shielding layer in the welding chamber 3, the limit ring 37 is pulled out, and the limit ring 37 close to the outlet of the welding chamber 3 is fixedly connected to a plurality of second motors 312 on its side close to the outlet of the welding chamber 3. The second motor 312 is fixedly connected to the upper surface of the inclined fixed block 311. The inclination of the fixed block 311 enables the second motor to face the submarine cable 6, so that the submarine cable 6 after arc welding can be physically cooled. Because the corrugated copper after arc welding has a high temperature, cooling it directly by spraying water will affect the hardness of the corrugated copper and the quality of the submarine cable 6. If cooling is not performed, the winding equipment may be damaged during the winding process, so the submarine cable 6 after arc welding is processed by physical cooling.

Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
