Description

Technical Field

[0001] The present invention relates to the field of marine engineering technology, and in particular to an umbilical cable assembly. Background Art

[0002] Ocean exploration and scientific expeditions typically consist of underwater equipment, a surface support vessel, and an umbilical cable connecting the vessel and the underwater equipment. Anchors are critical load-bearing components connecting the umbilical cable and the underwater equipment, preventing them from being lost.

[0003] FRP armored umbilical cables are non-metallic armored umbilical cables that use FRP (fiber reinforced plastic) as a reinforcement layer. Loose fiber filaments are glued together to form a circular FRP. Dozens of FRP strands are wrapped around the cable core to act as load-bearing elements. The anchoring principle of FRP armored umbilical cables is the same as other types of anchoring. They can be fixed by gluing or mechanical clamping. However, mechanical clamping can easily cause stress concentration in the FRP, leading to wear or breakage. Gluing, however, is less effective because FRP is a rod-like structure with a smaller surface area in contact with the glue. It can easily be pulled out of the glue when subjected to tension, resulting in poorer fixing. Summary of the Invention

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] See also Figures 1 to 5 As shown, the present invention provides an umbilical cable assembly, comprising: an umbilical cable 10, the umbilical cable 10 comprising a cable core 11 and a reinforcement layer 12; an anchoring inner tube 20, the anchoring inner tube 20 comprising a first installation cavity 21 and a wavy load-bearing portion 22, the cable core 11 being installed in the first installation cavity 21, and the reinforcement layer 12 being installed on the wavy load-bearing portion 22; and an anchoring outer tube 30, the anchoring outer tube 30 being sleeved on the outside of the anchoring inner tube 20, and at least part of the wavy load-bearing portion 22 being located in the inner cavity of the anchoring outer tube 30, a gap being present between the anchoring outer tube 30 and the anchoring inner tube 20, the gap being filled with glue, and the reinforcement layer 12 being arranged on the wavy load-bearing portion 22 located in the inner cavity of the anchoring outer tube 30.

[0032] In this embodiment, the cable core 11 of the umbilical cable 10 is installed in the first installation cavity 21 of the anchoring inner tube 20, which can protect the cable core 11. The reinforcement layer 12 is covered on the outer periphery of the wavy load-bearing part 22, and the anchoring outer tube 30 is sleeved on the outside of the anchoring inner tube 20. In this way, the anchoring outer tube 30 can be covered on the outer periphery of the reinforcement layer 12 to prevent the reinforcement layer 12 from being deformed or damaged by external force. The gap between the anchoring outer cylinder 30 and the anchoring inner cylinder 20 is filled with glue in order to fix the reinforcing layer 12 on the wavy load-bearing part 22. The wavy structure of the wavy load-bearing part 22 can increase the friction between the reinforcing layer 12 and the wavy load-bearing part 22, and can also increase the contact area between the reinforcing layer 12 and the glue. In this way, when the umbilical cable 10 is subjected to tension, it is not easy to be pulled out from the anchoring inner cylinder 20. At the same time, the wavy structure can also bear the force. When the umbilical cable 10 is subjected to a large tension, the umbilical cable 10 is not easy to break, thereby improving the service life of the umbilical cable 10 and the structural stability of the umbilical cable assembly.

[0033] like Figure 1 As shown, in one embodiment of the present invention, the outer wall 221 of the wavy load-bearing portion 22 is a continuous non-uniform wavy structure, and the outer wall 221 of the wavy load-bearing portion 22 appears as a wavy line in the cross section passing through the central axis of the anchor inner tube 20.

[0034] The bending radius of the outer wall 221 of the wavy load-bearing portion 22 gradually increases in a direction approaching the umbilical cable 10 .

[0035] In one embodiment of the present invention, the wave line includes at least two wave segments, and each wave segment is a sinusoidal function curve with a complete cycle.

[0036] Through the above arrangement, it is possible to ensure that two adjacent wave segments can be smoothly connected without destroying the wave segment structure, play a load-bearing role, and ensure that the reinforcement layer 12 will not easily fall off from the anchor inner tube 20 when subjected to tension.

[0037] In one embodiment of the present invention, the cable core 11 passes through one end of the anchoring inner tube 20, and the axial lengths and bending radii of two adjacent wave segments are different. The closer to the end where the cable core 11 passes through, the larger the axial length and bending radius.

[0038] In this embodiment, the cable core 11 passes through one end of the anchoring inner tube 20, and the passed-through cable core 11 may be subjected to tension. The closer the two adjacent wave segments are to the passing-through end of the cable core 11, the larger the axial length and the bending radius, and the flatter the wave segment. When the reinforcement layer 12 is subjected to tension, the wave segment closest to the passing-through end of the cable core 11 bears the least force. In this way, the subsequent multiple wave segments can evenly distribute most of the force, thereby making the tension distribution more reasonable, thereby avoiding the reinforcement layer 12 from being subjected to excessive tension at the wave segment closest to the passing-through end of the cable core 11, and causing it to break or detach from the wavy load-bearing part 22.

[0039] In one embodiment of the present invention, the material of the reinforcement layer 12 can be selected as FRP (fiber reinforced plastic), and the reinforcement column 121 is made of a plurality of loose fiber filaments bonded by glue.

[0040] like Figure 1 As shown, in one embodiment of the present invention, the umbilical cable assembly further includes a plurality of compression rings 40 , which are spaced apart on the wavy load-bearing portion 22 to fix the reinforcement layer 12 on the wavy load-bearing portion 22 .

[0041] In this embodiment, the pressure rings 40 are arranged at intervals on the wavy load-bearing portion 22 to fix the reinforcing layer 12 on the wavy load-bearing portion 22 to prevent the reinforcing layer 12 from axial movement when subjected to tension, thereby ensuring the structural stability of the reinforcing layer 12.

[0042] In one embodiment of the present invention, the pressure ring 40 is an open metal clamping ring structure, which is convenient for passing through to the buckling position. The pressure ring 40 is then tightened by hydraulic buckling. The opening distance of the pressure ring 40 should ensure that it is just closed after tightening, so as to tightly fix the dispersed reinforcement columns 121 on the wavy load-bearing part 22.

[0043] See also Figures 1 to 4As shown, in one embodiment of the present invention, the outer wall 221 also includes a plurality of wave crests 223, and the anchoring outer tube 30 includes a first pipe segment 31 and a second pipe segment 32 connected in sequence, the first pipe segment 31 and the second pipe segment 32 are connected, and a plurality of grooves 311 are arranged on the inner wall of the first pipe segment 31 at intervals, and the distance between the inner wall surface of each groove 311 and its corresponding wave crest 223 is a preset distance.

[0044] In this embodiment, a plurality of grooves 311 are provided on the first pipe section 31, so that the glue can solidify in the grooves 311 to form a card groove, thereby preventing the solidified glue from moving axially. In addition, the distance between the inner wall surface of each groove 311 and its corresponding wave crest 223 is a preset distance, and the preset distance is about 10 cm. This setting can ensure that the glue solidified in the groove 311 is difficult to pass through the wave crest 223, thereby ensuring the fixing effect of the reinforcing layer 12.

[0045] In one embodiment of the present invention, the groove 311 may be an annular groove.

[0046] See also Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the outer wall 221 includes a plurality of troughs 222 , and a pressure ring 40 is provided at each trough 222 .

[0047] In this embodiment, a pressure ring 40 is provided at each trough 222 of the outer wall 221, that is, the pressure ring 40 is located between two adjacent peaks 223, and is located at the position with the smallest diameter of the structure between the two peaks 223. The structures on both sides of the trough 222 can limit the pressure ring 40 in the axial direction to prevent the pressure ring 40 from escaping from the wavy load-bearing part 22 when the reinforcing layer 12 is subjected to a large tensile force, thereby realizing a combined fixing method of mechanical buckling and glue bonding, thereby increasing the tensile strength and safety margin of the reinforcing layer 12.

[0048] like Figure 1 As shown, in one embodiment of the present invention, one end of the anchoring inner tube 20 enters the inner cavity of the anchoring outer tube 30 from the first end of the anchoring outer tube 30 and then extends from the second end of the anchoring outer tube 30 and is clamped at the second end of the anchoring outer tube 30.

[0049] Through the above arrangement, the anchoring inner cylinder 20 can be limited in the anchoring outer cylinder 30, thereby ensuring that the relative positions of the two do not change, thereby improving the structural stability of the umbilical cable assembly.

[0050] See also Figures 1 to 4 As shown, in one embodiment of the present invention, the wavy load-bearing portion 22 further includes a tapered surface 224 , the diameter of the second pipe segment 32 gradually decreases in the direction away from the first pipe segment 31 , and the end of the second pipe segment 32 away from the first pipe segment 31 is clamped on the tapered surface 224 .

[0051] In this embodiment, the second tube section 32 is provided with an opening at the end away from the first tube section 31, and the diameter of the second tube section 32 gradually decreases as it approaches the opening. This allows the end of the wavy load-bearing portion 22 with the larger diameter of the tapered surface to be retained within the second tube section 32, preventing the anchor inner barrel 20 from separating from the anchor outer barrel 30 when subjected to external forces, thereby improving the structural stability of the umbilical cable assembly. Furthermore, the gradually decreasing diameter of the tapered surface 224 allows it to accommodate anchor outer barrels 30 with varying opening sizes, thereby improving the applicability of the anchor inner barrel 20.

[0052] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the umbilical cable assembly further includes a connector 50, one end of the connector 50 is provided with a second installation cavity 51, the end of the first pipe section 31 away from the second pipe section 32 is installed in the second installation cavity 51, and the other end of the connector 50 can be connected to the underwater equipment.

[0053] Through the above arrangement, the connection between the umbilical cable 10 and the underwater equipment can be achieved.

[0054] In one embodiment of the present invention, a pin hole is provided on the connecting member 50, and the connecting member 50 is connected to the underwater equipment through the pin hole, and specifically, a flange can be used for connection.

[0055] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the connecting member 50 also includes a plurality of first mounting holes 52, and the plurality of first mounting holes 52 are opened on the side wall of the second mounting cavity 51 and are all connected to the second mounting cavity 51. The first pipe section 31 includes a plurality of second mounting holes 312 arranged along the circumferential direction, and the plurality of second mounting holes 312 are arranged in a one-to-one correspondence with the plurality of first mounting holes 52.

[0056] In this embodiment, after the first pipe section 31 is installed in the second mounting cavity 51, the second mounting hole 312 on the first pipe section 31 corresponds one-to-one with the first mounting hole 52 on the connecting member 50, and bolts or screws are passed through the first mounting hole 52 and the second mounting hole 312 in sequence to fix the connecting member 50 to the anchoring outer tube 30.

[0057] In one embodiment of the present invention, a thread is provided at one end of the first pipe section 31 away from the second pipe section 32, and the inner wall of the second installation cavity 51 of the connecting piece 50 is correspondingly provided with a thread that can cooperate with the first pipe section 31, and the connecting piece 50 is connected to the anchoring outer tube 30 through a thread.

[0058] In one embodiment of the present invention, an anti-slip structure is provided on the outer wall 221 to increase the friction between the reinforcement layer 12 and the outer wall 221 .

[0059] The above arrangement can increase the friction between the reinforcement layer 12 and the outer wall 221 . When the reinforcement layer 12 is subjected to tension, the reinforcement layer 12 is less likely to move axially relative to the outer wall 221 , thereby improving the structural stability of the umbilical cable assembly.

[0060] In one embodiment, the curvature radius of the wave line satisfies a sine curve: Y=a i sin b i x, where a i is the first adjustment coefficient of the wave line, that is, the amplitude of the wave line, b i is the second adjustment coefficient of the wave line, that is, the period coefficient of the wave line. The larger bi is, the smaller the period is, and the smaller bi is, the larger the period is. y is the height coordinate of the wave line, and x is the width coordinate of the wave line.

[0061] In this embodiment, the first adjustment coefficient a i is the height coefficient of the wave line. The size of the first adjustment coefficient directly affects the size of the distance between the crest 223 and the trough 222 of the wave line, that is, the degree of curvature change of the wave line. The second adjustment coefficient b i is the width coefficient of the wave line. The size of the second adjustment coefficient directly affects the length of the wave line. The outer wall 221 set according to the above formula can reasonably distribute the tension exerted on the reinforcement layer 12, thereby ensuring the structural stability of the umbilical cable assembly.

[0062] In one embodiment of the present invention, the reinforcing layer 12 includes a plurality of reinforcing columns 121 , which have the same diameter and are wrapped around the wavy load-bearing portion 22 . The first adjustment coefficient is positively correlated with the diameter of the reinforcing column 121 , and the second adjustment coefficient is negatively correlated with the diameter of the reinforcing column 121 .

[0063] In this embodiment, the reinforcing layer 12 includes multiple reinforcing columns 121 of the same diameter, which are wrapped around the wavy load-bearing portion 22. The wavy structure of the wavy load-bearing portion 22 can increase the frictional resistance between each reinforcing column 121 and the wavy load-bearing portion 22, and can also increase the contact area between each reinforcing column 121 and the glue, so that when the reinforcing layer 12 is subjected to tension, the reinforcing columns 121 will not easily detach from the wavy load-bearing portion 22. The first adjustment coefficient is positively correlated with the diameter of the reinforcing column 121, and the second adjustment coefficient is negatively correlated with the diameter of the reinforcing column 121. That is, the thicker the reinforcing column 121, the larger the first adjustment coefficient of the wavy line, and the smaller the second adjustment coefficient.

[0064] In one embodiment of the present invention, the first adjustment coefficient a i The diameter D of the reinforcing column 121 satisfies the relationship: i =(i+3)D, the second adjustment coefficient b i The diameter D of the reinforcing column 121 satisfies the relationship: Where i is a positive integer.

[0065] In this embodiment, the first adjustment coefficient and the second adjustment coefficient and the diameter D of the reinforcement column 121 satisfy the above formula, where i is a positive integer, and the smaller the value of i, the closer the wave segment of the wave line is to the outlet end of the cable core 11, that is, the closer the wave segment is to the outlet end of the cable core 11, the smaller the first adjustment coefficient and the second adjustment coefficient of the wave segment, the flatter the wave segment, and the smaller the bearing force.

[0066] In one embodiment of the present invention, when the wave line includes three wave segments, the first adjustment coefficient a of the three wave segments is i The values ​​are a1=4D, a2=5D, a3=6D, and the second adjustment coefficient b i The corresponding value is

[0067] It can be seen from the above formula that the closer to the umbilical cable 10 , the smaller the period coefficient bi of the wave line, the larger the period, the smaller the amplitude ai, that is, the larger the bending radius of the wave line.

[0068] In one embodiment of the present invention, the anti-slip structure may be knurling, protrusions, or grooves.

[0069] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: an anchoring inner tube and an anchoring outer tube are provided, so that the cable core of the umbilical cable is installed in the first installation cavity of the anchoring inner tube to protect the cable core, the reinforcement layer of the umbilical cable is covered on the outer periphery of the wavy load-bearing part, the anchoring outer tube is sleeved on the outside of the anchoring inner tube, and the anchoring outer tube can be covered on the outer periphery of the reinforcement layer, which can prevent the reinforcement layer from being deformed or damaged by external force, and the gap between the anchoring outer tube and the anchoring inner tube is filled with glue, which can fix the reinforcement layer on the wavy load-bearing part, and then utilize the wavy structure of the wavy load-bearing part to increase the friction between the reinforcement layer and the wavy load-bearing part, and at the same time increase the contact area between the reinforcement layer and the glue, so that the umbilical cable is not easily pulled out when subjected to tension, and the wavy structure can also bear force, so that the umbilical cable is not easily broken when subjected to large tension, thereby improving the service life of the umbilical cable and the structural stability of the umbilical cable assembly.
