[0001] The invention belongs to the technical field of shipboard cables and corresponding processing devices, and specifically relates to a shipboard lightweight power cable and a processing device thereof. Background Art

[0002] Marine cables are wires and cables used for power, lighting, control, and communication transmission on various ships and offshore or offshore buildings, including marine power cables, marine control cables, and marine communication cables. Usually, the laying space for marine cables is limited, so the armored structure adopts metal wire weaving, which is the biggest difference in structure from ordinary land-based power, control, and communication cables.

[0003] However, since the cables contain a lot of metal, they are heavy. When used on ships, they will inevitably increase the load on the ship, which will increase the energy consumption of the ship during operation. At the same time, due to the armored structure on the surface and the heavy weight of the cables used on ships, when wiring, if you encounter a corner position, you may not be able to make a good turn. At the same time, when setting it on the wall, you need to consider whether the wall can bear the corresponding weight. Sometimes you need to set a bracket on the wall for support.

[0040] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The terms such as "upper", "inner", "middle", "left", "right" and "one" cited in this specification are only for the convenience of description, and are not used to limit the scope of the present invention. The change or adjustment of their relative relationship shall also be regarded as the scope of the present invention without substantially changing the technical content.

[0041] The light-weight shipboard power cable and the processing device thereof of the present invention are as follows: Figures 1 to 5As shown, the processing device is used to process the shipboard light power cable of the present invention. The shipboard light power cable of the present invention is provided with a fire-resistant tape 2 and a corrugated tube sheath 4 on the surface of a plurality of twisted conductors 1 to make the power cable light. The corrugated tube sheath 4 is used to improve the bending ability of the cable, so that the subsequent cable installation operation is simple and convenient, and the hull load can be effectively reduced. The shipboard light power cable of the present invention and its processing device are introduced in the form of embodiments.

[0042] Example 1

[0043] A lightweight power cable for ships, such as Figure 1 to Figure 2 As shown, it includes a plurality of twisted wires 1, a fire-resistant tape 2, and a corrugated tube sheath 4; the wire 1 includes a plurality of twisted conductors 11, the conductor 11 is made of aluminum alloy material, the diameter of the single-filament conductor 11 does not exceed 0.25 mm, so it has good flexibility, and the surface of the plurality of twisted conductors 11 is wrapped with an insulating layer 12. The fire-resistant tape 2 is wound on the surface of the plurality of twisted wires 1 to form a fire-resistant layer, wherein the fire-resistant tape 2 is made of glass fiber material and has better fire resistance. The corrugated tube sheath 4 is sleeved on the surface of the plurality of wires 1 with the fire-resistant tape 2, and the fire-resistant tape 2 on the surface of the plurality of twisted wires 1 abuts against the inner wall of the corrugated tube sheath 4.

[0044] The ship-borne lightweight power cable of the present invention also includes a heat-insulating and fire-proof layer 3, which is arranged on the surface of the fire-resistant layer so that the heat-insulating and fire-proof layer 3 is located between the fire-resistant layer and the corrugated tube sheath 4, wherein the heat-insulating and fire-proof layer 3 is made of mineral material and has better heat-insulating and fire-proofing effects.

[0045] In this embodiment, the insulating layer 12 is made of mica tape, which is also called fire-resistant mica tape and has good high temperature resistance and combustion resistance. The mica tape is wound around the surface of several twisted conductors 11 to form the insulating layer 12.

[0046] In this embodiment, the cross section of the bellows sheath 4 is corrugated, and the thread of the corrugation of the cross section of the bellows sheath 4 is arc-shaped, and the thickness of the bellows sheath 4 is 0.2 mm-1.0 mm; therefore, it has good bending ability and deformability. Among them, the bellows sheath 4 is made of 304 stainless steel material, so it can play the role of physical rodent prevention, termite prevention, anti-pressure protection, and avoid mechanical damage.

[0047] Therefore, the light-weight ship-use power cable of the present invention is provided with a fire-resistant tape 2, a heat-insulating fireproof layer 3 and a corrugated tube sheath 4 in sequence on a plurality of twisted conductors 1. Since the conductor 1 has a relatively thin diameter, and the fire-resistant tape 2 and the heat-insulating fireproof layer 3 are both made of lightweight materials, the structure thereof has the characteristics of being non-plasticized, and the production process does not require processing. At the same time, the overall weight of the cable structure produced is light, and the load on the hull can be reduced when applied on board. In addition, due to the provision of the fire-resistant tape 2 and the heat-insulating fireproof layer 3, the cable has the advantages of being fire-resistant, high-temperature resistant, non-self-igniting, non-flammable, and non-conductive. At the same time, due to the provision of the corrugated tube sheath 4, the cable of the present invention forms an armored structure with flexibility and freedom of bendability, which can effectively prevent rats and termites physically, and has good anti-pressure protection capability to avoid mechanical damage. During wiring, the cable can be freely bent for installation, and has the advantage of convenient installation and operation.

[0048] Example 2

[0049] A processing device for a light-weight marine power cable, such as Figures 1 to 4 As shown, the device for processing the shipborne lightweight power cable of the above-mentioned embodiment 1 mainly includes a discharge drum 5, a corrugation processing device 6, a movable clamping device 7, and a receiving drum; the discharge drum 5 of the present invention is used to roll up the semi-finished product of the above-mentioned shipborne lightweight power cable, and the corrugated tube sheath 4 of the semi-finished product of the shipborne lightweight power cable is a semi-finished thin tube at this time; the corrugation processing device 6 is used to process the surface of the thin tube to form corrugations, so that the thin tube is processed into a corrugated tube sheath 4; the movable clamping member 712 is used to clamp the parts on both sides of the corrugation processing device 6 in the shipborne lightweight power cable to be processed, and then feed the material to the receiving drum in a quantitative manner. During this process, the corrugation processing device 6 synchronously corrugates the thin tube, and at the same time, the movable clamping member 712 can better reduce the self-rotation of the shipborne lightweight power cable.

[0050] The discharging barrel 5 of the present invention adopts an electrically controlled discharging barrel 5 , that is, the function of forward rotation to collect materials or reverse rotation to discharge materials can be realized through the control of a motor.

[0051] The corrugation processing device 6 of the present invention is arranged on one side of the discharge barrel 5, and the corrugation processing device 6 includes a rotating member 61. The rotating end of the rotating member 61 is provided with a ring body 62, and the inner wall of the ring body 62 is provided with corrugated screw threads 624. When the thin tube passes through the ring body 62, the rotating member 61 drives the ring body 62 to rotate so that the corrugated screw threads 624 squeeze the surface of the thin tube to produce corrugations.

[0052] In this embodiment, Figures 3 to 5As shown, in order to realize the function of using the rotating member 61 to drive the ring body 62 to rotate. The processing device of the present invention also includes a bracket 63 provided with a connecting ring 631, the cross section of the connecting ring 631 is T-shaped, and the side of the ring body 62 is provided with an annular groove 625, the cross section of the annular groove 625 is T-shaped, the connecting ring 631 is adapted to the annular groove 625, and the ring body 62 rotates about the axis of the connecting ring 631. The outer peripheral surface of the ring body 62 is provided with a tooth surface 623 along the annular direction, and the rotating member 61 includes a driving member, and the driving end of the driving member is connected to a driving gear 612, and the driving gear 612 is meshed with the tooth surface 623 of the ring body 62, and the driving member drives the driving gear 612 to rotate, and the driving gear 612 drives the ring body 62 to rotate.

[0053] In this embodiment, in order to facilitate the corrugated screw thread 624 to extrude corresponding corrugations on the surface of the thin tube, the corrugated screw thread 624 of the ring body 62 includes an initial pressing section 6241, a transition section 6242 and a pressing section 6243, the initial pressing section 6241 is located on the side close to the discharge barrel 5, the pressing section 6243 is located on the side close to the receiving barrel, the initial pressing section 6241, the transition section 6242 and the pressing section 6243 have the same screw thread spacing, the initial pressing section 6241, the transition section 6242 and the pressing section 6243 have screw thread depths that increase in sequence, the screw thread of the initial pressing section 6241 is trapezoidal (the trapezoid is specifically an isosceles trapezoid), the screw thread of the transition section 6242 is a chamfered trapezoid (the chamfered trapezoid is specifically an isosceles trapezoid with two chamfered corners), and the screw thread of the pressing section 6243 is arc-shaped.

[0054] Therefore, by dividing the corrugated thread 624 into an initial pressing section 6241, a transition section 6242 and a pressing section 6243, since the thread spacing between the three is the same, the depth gradually increases, and the shape gradually transitions from a trapezoid with edges to a rounded and arc-shaped shape, the ability of the corrugated thread 624 to extrude thin tubes to form corrugations can be gradually improved. Specifically, when the thin tube is squeezed by the initial pressure section 6241, the two vertex angles of the isosceles trapezoid of the initial pressure section 6241 will squeeze the surface of the thin tube and cause deformation, so as to achieve the function of better destroying surface stress; further, when the thin tube is squeezed by the transition section 6242, the two rounded corners of the rounded trapezoid of the transition section 6242 will further squeeze the position of the thin tube that was previously squeezed and deformed by the vertex angle of the initial pressure section 6241, so as to cause the position to further produce a deeper deformation; finally, when the thin tube is squeezed by the pressing section 6243, the arc surface can be used to completely squeeze the part of the thin tube that was previously squeezed by the transition section 6242 into an arc, and it can be completely fitted with the inner wall of the pressing section 6243. At the same time, in the process that the rotating member 61 continuously drives the ring body 62 to rotate and the linear moving member 71 drives the ship's lightweight power cable to continuously move forward, the corrugated screw thread 624 on the inner wall of the ring body 62 can be used to produce corresponding corrugations on the surface of the thin tube, so that the thin tube forms the corrugated tube sheath 4 of Example 1, and is processed to form the ship's lightweight power cable of the example.

[0055] At the same time, a fixing ring 621 is provided at one end of the ring body 62 close to the discharge barrel 5. The fixing ring 621 is made of a heat-conducting material. The ring opening of the fixing ring 621 is directly opposite to the ring opening of the ring body 62. The ring opening of the fixing ring 621 is larger than the ring opening of the ring body 62. A spirally distributed heating element 622 is embedded on the inner circumference of the fixing ring 621. The heating element 622 can use an electric heating wire. Therefore, the heating element 622 can first preheat the surface of the thin tube to facilitate the subsequent corrugation processing.

[0056] like Figures 3 to 5 As shown, the mobile clamping device 7 of the present invention includes a linear moving member 71 and two clamping members 712. The linear moving member 71 has two sliders 711. The linear moving member 71 drives the two sliders 711 to move synchronously. The moving direction of the slider 711 is the connecting line between the discharge cylinder 5 and the corrugation processing device 6. The two clamping members 712 are respectively arranged on the two sliders 711. The two clamping members 712 are respectively arranged on both sides of the corrugation processing device 6, and are used to clamp the front end and the rear end of the thin tube respectively to limit the self-rotation of the thin tube, thereby improving the effectiveness of processing corrugations of the thin tube, and having the beneficial effect of improving processing efficiency.

[0057] In this embodiment, the linear moving member 71 adopts a screw module, and the two sliders 711 are both slidably connected to the base of the screw module, and the two sliders 711 are both matched with the screw thread of the screw module, so that the screw module is used to drive the two sliders 711 to move linearly. The clamping member 712 of this embodiment adopts a clamping cylinder, and a buffer member 713 is provided on the inner side of the clamping arm of the clamping cylinder. The buffer member 713 can be a rubber pad. Therefore, when the corrugation processing device 6 performs corrugation processing on the thin tube, the clamping member 712 and the rubber pad can be used to firmly clamp the thin tube, and the screw module is used to synchronously transmit the processed thin tube and the power cable receiving barrel attached inside.

[0058] The distance between the two clamping members 712 is 5 to 7 times the width of the corrugation processing device 6 in the direction of the line connecting the two clamping members 712. Therefore, by limiting the distance between the two clamping members 712, it is mainly to maintain the tensile stress of the middle position between the two clamping members 712 in the corrugated tube within a larger stress range, thereby reducing the self-rotation of the thin tube, so as to achieve the effectiveness of processing and improve processing efficiency.

[0059] The material receiving drum of the present invention is used for winding up the processed shipboard lightweight power cable of Example 1.

[0060] In summary, the processing device of the present invention is provided with a discharge cylinder 5, a corrugation processing device 6, a mobile clamping device 7 and a receiving cylinder to process the ship's lightweight power cable of the present invention. The discharge cylinder 5 is used to discharge the material and the receiving cylinder is used to receive the material synchronously, so that the semi-finished power cable between the two can be in a relatively horizontal state and can be transmitted forward; in this process, the two clamping members 712 of the mobile clamping device 7 can be used to clamp the front and rear ends of the thin tube, and then the two clamping members 712 and the clamped thin tube are driven to move forward synchronously by the linear moving member 71. In this process, the rotating member 61 drives the ring body 62 to rotate, and at the same time, the corrugated screw thread 624 inside the ring body 62 is used to squeeze the surface of the thin tube to form corresponding corrugations, thereby making the thickness of the thin tube thinner and realizing the function of arbitrary bending.

[0061] The implementation methods of the present invention are not limited to this. According to the above content of the present invention, using common technical knowledge and customary means in the field, without departing from the above basic technical ideas of the present invention, the present invention can also make other various forms of modification, replacement or combination, all of which fall within the scope of protection of the present invention.
