Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a self-inductive high-tensile strength aluminum alloy floating cable and a connector thereof. Background Art

[0002] Aluminum alloy floating cables are specialized cables that combine aluminum alloy materials with floating properties. They offer advantages such as light weight, high strength, corrosion resistance, excellent conductivity, and floatability. They are primarily used for power transmission in offshore wind farms, signal transmission and power supply for underwater drones, and underwater exploration and construction. In these applications, the cables must withstand harsh marine environments, significant mechanical stress, and complex electrical requirements.

[0003] Conventional floating cables generally lack tensile strength, but high tensile strength is a key characteristic of these cables. This means they can withstand significant mechanical stress and are less susceptible to breakage or deformation. This is particularly important for floating cables, which must withstand harsh marine environments such as strong winds and high waves. High tensile strength ensures the cable's stability and reliability over long-term operation. Consequently, current floating cables are susceptible to breakage between the aluminum alloy conductor and the electrical connector when the cable is dragged, leading to disconnection and failure between the cable and the connector, impacting the normal transmission of electricity. Summary of the Invention

[0004] The purpose of the present invention is to provide a self-sensing high-tensile strength aluminum alloy floating cable and its connector to solve the following technical problems:

[0028] Beneficial effects of the present invention:

[0030] (2) When positioning and fixing the cable body, the present invention first inserts the cable body along the open end of the slitting box. Before insertion, the angle of the cable body is adjusted so that the position of the reserved gap in the cable body corresponds to the position of the slitting knife. During the insertion process, each slitting knife cuts the tensile outer sheath along the reserved gap to form several groups of tensile parts. The tensile parts can continuously withstand the tensile force, thereby avoiding disconnection between the cable body and the electrical connector. At the same time, each aluminum alloy conductor can be exposed to facilitate subsequent electrical connection between each aluminum alloy conductor and the electrical connector. Therefore, the present invention can realize the slitting process of the tensile outer sheath during the positioning of the cable body, without the need for manual slitting, and the operation is convenient;

[0031] (3) When positioning the cable body, the present invention can embed each protrusion into the reserved gap, thereby increasing the friction between the protrusion and the aluminum alloy conductor, making the positioning of the cable body in the tensile connector more stable, and strengthening the cable body structure, further improving its tensile performance;

[0032] (4) In the initial state of the present invention, there is a certain distance between the pressing plate and the inclined surface, and the cut tensile portion can slide forward along the channel formed between the pressing plate and the inclined surface. When the cable body stops being inserted, the pressing plate is driven by the driving portion to move toward the positioning plate to press the tensile portion between the pressing plate and the inclined surface. After the tensile portion is locked, when the cable body is pulled, the tensile portion can continue to withstand the tension, thereby preventing the cable body from being disconnected from the electrical connector.

[0033] (5) When the pressure plate of the present invention moves toward the positioning plate, the positioning seat can press the tensile part into the positioning groove, thereby further improving the pressing effect of the tensile part; when the positioning seat presses the tensile part into the positioning groove, the limiting plate can be pressed synchronously, and the limiting plate squeezes the arc plate through the support rod and the pressure wheel, so that the connection between the arc plate and the aluminum alloy conductor is tighter.

DETAILED DESCRIPTION

[0052] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0053] Example 1

[0054] See also Figure 1 As shown, the present invention is a self-sensing high-tensile-strength aluminum alloy floating cable, including a cable body 2. The cable body 2 is sequentially arranged with a foamed TPU sheath 201, an aramid filler 202, and a foamed TPE inner sheath 203 from the outside to the inside. The foamed TPU sheath 201, the aramid filler 202, and the foamed TPE inner sheath 203 are combined to form a tensile-resistant outer sheath. Specifically, in this embodiment, the density of the foamed TPU sheath 201 and the foamed TPE inner sheath 203 are both lower than that of water, which can provide buoyancy to the cable body 2. At the same time, the aramid filler 202 has excellent tensile properties, which can protect the cable body 2 from being broken. The aramid filler is directly placed to ensure its tensile strength.

[0055] In this embodiment, several groups of aluminum alloy conductors 205 are arranged in a circumferential array within the tensile outer sheath. A group of aluminum alloy conductors 205 is also arranged at the axial end of the sheath. Each aluminum alloy conductor 205 is coated with a foamed TPE insulation 206. Each group of aluminum alloy conductors 205 arranged in the circumferential array abuts against each other, and the side away from the axis of the tensile outer sheath abuts against the TPE inner sheath 203. A reserved gap 204 is formed between two adjacent groups of aluminum alloy conductors 205 and the TPE inner sheath 203. Specifically, in this embodiment, there are seven groups of aluminum alloy conductors 205 arranged in the circumferential array. The specific number is not limited in this embodiment, as long as it meets the actual conductivity requirements of the floating cable.

[0056] It should be noted that, in this embodiment, a reserved gap 204 is formed between each two adjacent groups of aluminum alloy conductors 205 and the TPE inner sheath 203. The reserved gap 204 is not filled with material, and the floating ability of the cable body 2 is further improved by the action of air.

[0057] Among them, the support material 207 is filled between the aluminum alloy conductor 205 located at the axial end and the aluminum alloy conductors 205 arranged in a circumferential array; specifically, the partially filled support material 207 can achieve the effect of positioning and supporting each aluminum alloy conductor 205. Accordingly, the support material 207 can use a watertight filler, and the watertight filler is selected from high-strength tensile bulletproof wire (Kevlar) / high-strength fiber, which can further enhance the tensile strength of the cable body 2.

[0058] Example 2

[0059] Based on Example 1, please refer to Figure 2-Figure 3 A connector for a self-inductive high-tensile-strength aluminum alloy floating cable includes a tensile connector 1 for fixing a cable body 2, the other end of the tensile connector 1 being connected to an electrical connector 3. Specifically, in this embodiment, the cable body 2 is positioned and fixed by the tensile connector 1, and the electrical connector 3 is fixed to the other end of the tensile connector 1. At the same time, each aluminum alloy conductor 205 in the cable body 2 is electrically connected to the electrical connector 3 to achieve power transmission.

[0060] In this embodiment, please refer to Figure 4 as well as Figure 6-Figure 7 The end of the tensile connector 1 away from the electrical connector 3 is fixedly provided with a splitting box 101, and a plurality of group cutters 401 are arranged in a circumferential array in the splitting box 101. The number of the splitting knives 401 is equal to the number of the reserved gaps 204 in the cable body 2, so as to split the tensile outer sheath on the cable body 2 into a plurality of groups of tensile parts 208 (see Figure 12 ), wherein a positioning module is arranged in the tensile connector 1 for positioning and fixing the tensile portion 208; it can be explained that when positioning and fixing the cable body 2, the cable body 2 is first inserted along the open end of the cutting box 101, and before insertion, the angle of the cable body 2 is adjusted so that the position of the reserved gap 204 in the cable body 2 corresponds to the position of the cutting knife 401. During the insertion process, each cutting knife 401 cuts the tensile outer sheath along the reserved gap 204 to form several groups of tensile portions 208. The tensile portions 208 can continuously withstand tension, thereby avoiding disconnection between the cable body 2 and the electrical connector 3. At the same time, each aluminum alloy conductor 205 can be exposed to facilitate subsequent electrical connection of each aluminum alloy conductor 205 to the electrical connector 3. Therefore, this embodiment can realize the cutting process of the tensile outer sheath during the positioning of the cable body 2, without the need for manual cutting, and the operation is convenient.

[0061] It should also be noted that this embodiment not only improves the floating effect of the cable body 2 itself by reserving a gap 204 in the cable body 2, but also provides a buffer groove for the slitting knife 401 during the slitting process to prevent the slitting knife 401 from cutting too deep and causing damage to the aluminum alloy conductor 205.

[0062] See also Figure 7-10The positioning module includes positioning plates 5 arranged in a circumferential array in the tensile connector 1, and each group of positioning plates 5 is fixed by a positioning ring 503. The two sides of the end of each positioning plate 5 close to the axial end of the connector 1 are symmetrically provided with arc surfaces 506, and a protrusion 507 for embedding into the reserved gap 204 is formed between the two groups of arc surfaces 506, wherein an inclined surface 501 is provided at the end of the positioning plate 5 away from the protrusion 507, and in the extending direction from the cutting box 101 to the electrical connector 3, the distance between the inclined surface 501 and the axial end of the connector 1 gradually increases; it can be explained that after each slitting knife 401 cuts the tensile outer sheath, as the cable body 2 continues to be inserted, the protrusion 507 can be embedded in the reserved gap 204, and based on the setting of the inclined surface 501 on the positioning plate 5, the tensile part 208 after cutting can be propped up in a diffuse shape (see Figure 12 ) to facilitate the subsequent positioning and fixing of the tensile portion 208.

[0063] It should also be noted that, in this embodiment, when positioning the cable body 2, each protrusion 507 can be respectively embedded in the reserved gap 204, which can increase the friction between the protrusion 507 and the aluminum alloy conductor 205, so that the positioning stability of the cable body 2 in the tensile connector 1 is higher, and the structure of the cable body 2 can be strengthened to further improve its tensile performance.

[0064] For further information, see Figure 4 and Figure 12 The positioning module also includes a pressure plate 6 arranged in a circumferential array in the connector 1, and the pressure plate 6 is arranged parallel to the inclined surface 501. A driving part is also provided in the connector 1, and the driving part is used to drive the pressure plate 6 toward or away from the axial end of the connector 1; it can be explained that in the initial state, there is a certain distance between the pressure plate 6 and the inclined surface 501, and the cut tensile part 208 can slide forward along the channel formed between the pressure plate 6 and the inclined surface 501. When the cable body 2 stops being inserted, the pressure plate 6 is driven by the driving part to move toward the direction of the positioning plate 5 to press the tensile part 208 between the pressure plate 6 and the inclined surface 501. After the tensile part 208 is locked, when the cable body 2 is pulled, the tensile part 208 can continue to withstand the tension, thereby avoiding disconnection between the cable body 2 and the electrical connector 3.

[0065] In order to securely connect the connector 1 to the electrical connector 3, in this embodiment, refer to Figure 5-Figure 6 An external thread 104 is provided on the outer wall of the end of the connector 1 away from the cutting box 101, and the electrical connector 3 is rotated to arrange the connecting cylinder 301 toward the end of the connector 1, and the inner wall of the connecting cylinder 301 is provided with an internal thread; it can be explained that after the cable body 2 is positioned, the connecting cylinder 301 at the end of the electrical connector 3 can be fixed to the connector 1 by a threaded connection, and the threaded connection method can be easily disassembled.

[0066] In this embodiment, the driving part includes an inclined plate 602 fixedly arranged at the end of the pressure plate 6, the inclined plate 602 is located at the end of the pressure plate 6 away from the slitting box 101, and the inclined plate 602 is inclined in the direction close to the axial end of the connector 1, and each pressure plate 6 is fixedly provided with a knife rod 603 that is slidably plugged into the wall of the connector 1, and a first spring 604 is provided on the knife rod 603, one end of the first spring 604 is fixed to the wall of the connector 1, and the other end is fixed to the pressure plate 6; wherein, a guide cylinder 302 fixed to the electrical connector 3 is also arranged in the connecting cylinder 301, and an annular groove 303 for embedding the connector 1 is formed between the guide cylinder 302 and the connecting cylinder 301, and a plurality of groups of guide wheels 305 corresponding to the inclined plates 602 are arranged in a circumferential array on the inner side of the guide cylinder 302. ; It can be explained that, in the initial state, based on the setting of the first spring 604, there is a certain distance between the pressure plate 6 and the positioning plate 5. After the cable body 2 is inserted into the corresponding position in the connector 1, when the electrical connector 3 is connected to the connector 1, as the connecting tube 301 is rotated, the end of the connector 1 can be embedded in the annular groove 303. During this process, the guide wheel 305 can drive the pressure plate 6 to move toward the axial end of the connector 1 by rolling and abutting with the inclined plate 602, thereby shortening the distance between the pressure plate 6 and the positioning plate 5, so as to press the tensile part 208 between the pressure plate 6 and the positioning plate 5. At this time, the first spring 604 can stretch and generate elastic force. Accordingly, when the connector 1 and the electrical connector 3 are removed, the first spring 604 can drive the pressure plate 6 to automatically reset.

[0067] It should also be noted that, please refer to Figure 8 In this embodiment, by providing an inclined plate 602 , when the tensile portion 208 is pressed and positioned, the inclined plate 602 is inclined inwardly, so that the tensile portion 208 can be bent, thereby further pressing the tensile portion 208 .

[0068] See Figure 5 In this embodiment, the electrical connector 3 is provided with a plurality of conductive holes 306 at one end thereof that is close to the connector 1, for embedding the aluminum alloy conductors 205. It can be explained that, after the cable body 2 of this embodiment is positioned, as the electrical connector 3 is connected to the connector, the aluminum alloy conductors 205 in the cable body 2 can be respectively embedded in the conductive holes 306, thereby realizing electrical connection between the aluminum alloy conductors 205 and the conductive holes 306. In this embodiment, after the cable body 2 is positioned, it is only necessary to remove the foamed TPE insulation 206 and the supporting material 207 on the plug-in end of the aluminum alloy conductor 205 and the conductive hole 306. The operation is very convenient and does not require manual wiring.

[0069] In addition, see Figure 5 and Figure 6During the connection process between the connector 1 and the electrical connector 3, when the connecting cylinder 301 is rotated, in order to avoid synchronously driving the electrical connector 3 to rotate, a plurality of groups of guide grooves 304 are provided on the outer wall of the guide cylinder 302 in a circumferential array, and a plurality of groups of guide seats 105 are correspondingly fixedly arranged on the inner side wall of one end of the connector 1 that is close to the electrical connector 3; it can be explained that in this embodiment, when the connector 1 and the electrical connector 3 are connected, the guide grooves 304 on the guide cylinder 302 can be plugged into the guide seats 105 on the connector 1 one by one, thereby stabilizing the electrical connector 3 and avoiding the misalignment phenomenon when the aluminum alloy conductor 205 and the conductive hole 306 are connected.

[0070] See also Figure 7-Figure 9 as well as Figure 12 In order to further improve the pressing effect on the anti-tensile part 208, in this embodiment, a positioning groove 502 is opened on the inclined surface 501, and a positioning seat 601 corresponding to the positioning groove 502 is fixedly arranged on the side of the pressure plate 6 close to the positioning plate 5; it can be explained that in the process of the pressure plate 6 moving toward the positioning plate 5, the anti-tensile part 208 can be pressed into the positioning groove 502 through the positioning seat 601, thereby further improving the pressing effect of the anti-tensile part 208.

[0071] For further information, see Figure 8-Figure 9 as well as Figure 11 , a through groove 7 is provided on the groove wall of the arc-shaped surface 506 on both sides, and a curved plate 701 is slidably embedded in the through groove 7, and an empty groove 505 is provided in the positioning plate 5, and the curved plate 701 is fixed with a second spring 702 fixedly arranged in the empty groove 505, wherein a pressure wheel 704 is further arranged in the empty groove 505, and the pressure wheel 704 abuts against the arc-shaped plates 701 on both sides, and a limiting plate 504 is slidably embedded in the positioning groove 502, and the limiting plate 504 is connected to the pressure wheel 7 through the support rod 703. 04 is fixed on the wheel frame, and the support rod 703 is slidably plugged into the bottom of the positioning groove 502; it can be explained that in the initial state, each arc plate 701 is in a state of being embedded in the through groove 7. When the positioning seat 601 presses the tensile part 208 into the positioning groove 502, the limit plate 504 can be pressed synchronously. The limit plate 504 squeezes the arc plate 701 through the support rod 703 and the pressure wheel 704 to make its connection with the aluminum alloy conductor 205 tighter.

[0072] In this embodiment, in order to facilitate the adjustment of the cutting depth of each cutting knife 401, please refer to Figure 6-Figure 8 as well as Figure 13, a knife ring 4 is fixedly arranged in the slitting box 101, and each slitting knife 401 is fixed to a knife rod 402 slidably arranged on the knife ring 4. An adjusting ring 404 is rotatably arranged on one side of the knife ring 4. A plurality of guide frames 406 are fixedly arranged on the inner side of the adjusting ring 404 in a circumferential array. An arc groove 407 is provided in the guide frame 406. The arc groove 407 extends from the near ring center end to the far ring center end. A pin 403 fixed to the end of the knife rod 402 is slidably embedded in the arc groove 407. Among them, a guide shaft 405 is also fixed on the adjusting ring 404. The guide shaft 405 is slidably embedded in the U-shaped groove 408 provided on the adjusting plate 409. An adjusting screw 102 is spirally arranged on the slitting box 101. The adjusting screw 102 It is rotatably connected to the adjustment plate 409; it can be explained that when adjusting the slitting depth of each slitting knife 401, the adjusting screw 102 is rotated to drive the adjusting plate 409 to rise and fall. During the lifting process of the adjusting plate 409, the guide shaft 405 can be driven to slide in the U-shaped groove 408, thereby driving the adjusting ring 404 to rotate. During the rotation of the adjusting ring 404, based on the guiding effect of the arc groove 407 on the pin shaft 403, the slitting knife 401 can be driven to move toward or away from the ring core end. Accordingly, in the initial state, the distance between each slitting knife 401 and the ring core end is large. When the cable body 2 needs to be inserted, the slitting knives 401 can be adjusted to gather together to facilitate cutting the tensile outer sheath.

[0073] See Figure 6 A tapered cylinder 103 is provided at the open end of the slitting box 101 on the side away from the connector 1; specifically, when the cable body 2 is subjected to tension, the cable body 2 contacts the tapered surface of the tapered cylinder 103 to avoid surface wear of the cable body 2. Accordingly, several groups of pressure sensors can be circumferentially arranged on the tapered surface of the tapered cylinder 103. When the cable body 2 contacts the tapered surface, the pressure can be detected in real time by the pressure sensor, so that the staff can understand the working condition of the cable body 2 and then make adaptive adjustments.

[0074] A method for connecting a connector of a self-inductive high-tensile strength aluminum alloy floating cable comprises the following steps:

[0075] See also Figure 1 as well as Figure 6-Figure 8 , S1, adjust the angle of the cable body 2 so that the position of the reserved gap 204 in the cable body 2 corresponds to the position of the slitting knife 401, and insert the cable body 2 along the open end of the slitting box 101;

[0076] S2. During the insertion process, each slitting knife 401 cuts the tensile outer sheath along the reserved gap 204 to form a plurality of groups of tensile portions 208;

[0077] S3, the cut tensile portion 208 slides forward along the channel formed between the pressing plate 6 and the inclined surface 501;

[0078] S4. After the cable body 2 stops being inserted, the driving unit drives the pressing plate 6 to move toward the positioning plate 5 to press the tensile portion 208 between the pressing plate 6 and the inclined surface 501.

[0079] S5. After the tensile portion 208 is locked, the connecting tube 301 at the end of the electrical connector 3 is fixed to the connector 1 by threaded connection.
