[0002] In the related technology, ocean exploration robots, underwater remote-controlled drone submersibles, underwater cameras, underwater construction equipment, underwater search and rescue robots, pipeline detection robots, submersible pumps, and various underwater electrical equipment are connected to shore-based equipment through cables. When the equipment is working on the surface or underwater, it needs to move forward continuously, so the cable will continue to extend. During this process, the equipment needs to continuously drag the cable, so the cable needs to float on the sea surface for a long time. If the cable sinks into the water, it will increase the tension on the cable during the equipment's advancement, thereby reducing the speed of the equipment's advancement in the sea.

[0003] At present, the cable is generally connected to a floating device through a cable, such as a buoy-type floating cable. A buoy sleeve is set on the outside of the cable body to increase the buoyancy, or a floating board is laid on the water surface and the cable is placed on the floating board. This makes the cable inconvenient to use, and the buoy sleeve and the floating board are easily affected by the impact of waves and deflected to a large extent, thereby causing the cable to deflect to a large extent, which can easily cause damage to the cable or the cable to pull the equipment to yaw and retreat.

[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] A first aspect of the present invention provides a floating cable, such as Figure 1 and Figure 2 As shown, the floating cable comprises a cable body 100, which is suitable for transmitting data or electricity, and a floating sleeve 200, which is coated on the outside of the cable body 100, and can make the cable body 100 float on the water surface, and the outside of the floating sleeve 200 is a streamlined structure.

[0031] It should be noted that the floating sleeve 200 is sleeved on the outside of the cable body 100, which can make the cable body 100 float on the water surface. The floating cable is easy to use. The outside of the floating sleeve 200 has a streamlined structure. When impacted by waves, the streamlined structure can reduce the resistance with water, thereby helping to reduce the offset of the floating cable.

[0032] It should also be noted that the floating sleeve 200 is covered on the outside of the cable body 100 and serves as a protective sleeve of the cable body 100 , and can also protect the cable body 100 .

[0033] In some embodiments of the present invention, the flotation sleeve 200 comprises foamed polyurethane.

[0034] It should be noted that the floating cover 200 is made of foamed polyurethane material, which is light in weight and has excellent floating ability on water and can float on the water for a long time. Foamed polyurethane has high strength, high toughness, good wear resistance, and can also provide excellent waterproof function, so it can be used as the outermost protective cover of the floating cable.

[0035] Among them, the foamed polyurethane can be made of raw materials such as isocyanate and polyether, under the action of various additives such as foaming agent, flame retardant, catalyst, etc., through high-pressure polyurethane spraying equipment or other methods, so that the two liquids collide at high speed and rotate violently in the mixing chamber, and after sufficient mixing, fine mist droplets are formed at the spray gun mouth, and evenly sprayed onto the surface of the cable body 100, and the floating cover 200 of the floating cable is formed by on-site foaming. Of course, the foamed polyurethane can also be set on the outside of the cable body 100 in other ways to form the floating cover 200. And the outside of the floating cover 200 of the foamed polyurethane material is a streamlined structure.

[0036] It should also be noted that the floating cover 200 may also be made of other materials, such as high-density foam plastics, etc. Those skilled in the art may determine the method according to actual conditions, and no specific limitation is made here.

[0037] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the outer sides of the floating sleeve 200 along the width direction are in an arc-shaped structure 210 .

[0038] like Figure 1 As shown, the floating cable is close to a flat structure, that is, the floating cover 200 is close to a flat structure, which can improve the buoyancy of the floating cover 200. The cable body 100 is arranged inside the floating cover 200. The outer sides of the floating cover 200 along the width direction are arc-shaped structures 210, which can reduce the resistance with water when impacted by waves, thereby reducing the deviation of the floating cable.

[0039] In some embodiments of the present invention, Figure 1 As shown, at least one side of the floating sleeve 200 along the thickness direction is set as a curved surface structure 220, and both ends of the curved surface structure 220 are respectively connected to the arc-shaped structures 210 on both sides.

[0040] like Figure 1 As shown, the floating cover 200 is close to a flat structure, and at least one side of the floating cover 200 along the thickness direction is set as a curved surface structure 220, and the two ends of the curved surface structure 220 are respectively connected to the arc-shaped structures 210 on both sides. The side wall of the floating cover 200 is a curved surface structure 220, so that the resistance with water can be further reduced, thereby reducing the offset of the floating cable.

[0041] When one side of the floating sleeve 200 along the thickness direction is set as the curved surface structure 220, when the floating cable is in use, the side with the curved surface structure 220 can be set upward.

[0042] In some embodiments of the present invention, both sides of the floating sleeve 200 along the thickness direction are set as curved structures 220. This can further reduce the resistance with water, thereby reducing the offset of the floating cable. When the floating cable is in use, both sides can be set upward or downward, which improves the convenience of using the floating cable.

[0043] The curved surface structure 220 may be an “S” shaped structure.

[0044] In some embodiments of the present invention, the two curved surface structures 220 are symmetrically arranged.

[0045] It should be noted that both sides of the floating sleeve 200 along the thickness direction are provided with curved structures 220, and the two curved structures 220 are symmetrically arranged. The arc structures 210 on both sides can be semicircular structures, and the two ends of the curved structure 220 are respectively connected to the ends of the arc structures 210 on both sides.

[0046] In some embodiments of the present invention, Figure 1 As shown, two cable bodies 100 are provided, and the two cable bodies 100 are respectively arranged inside two arc-shaped structures 210 .

[0047] It should be noted that if Figure 1 As shown, two cable bodies 100 are provided, and the two cable bodies 100 are respectively arranged inside two arc-shaped structures 210. By providing two cable bodies 100, the floating cable can be kept balanced in the water.

[0048] It should also be noted that the weights of the two cable bodies 100 may be the same or similar, and the two cable bodies 100 may be symmetrically arranged, thereby improving the balance of the floating cable in water.

[0049] In some embodiments of the present invention, Figure 1 As shown, the floating cable further includes a plurality of tension members 300 , the floating sleeves 200 are coated on the outside of the tension members 300 , and the tension members 300 are located between the two cable bodies 100 .

[0050] like Figure 1 As shown, it should be noted that the floating cable also includes a plurality of tension members 300, and the tension members 300 are arranged in the floating sleeve 200. The tension members 300 can improve the tensile performance of the floating cable. After the floating cable is connected to the underwater robot, the floating cable needs to withstand a certain tensile force, and when the underwater robot is out of the water, the floating cable needs to provide a certain tensile force for the underwater robot to get out of the water. By setting the tension members 300, the strength of the floating cable can be improved, and the floating cable can withstand a certain tensile force, and there is no need to set an additional cable.

[0051] It should also be noted that the cable body 100 can have a certain tensile strength, and the plurality of tensile members 300 are disposed between two cable bodies 100 , thereby further improving the tensile strength of the overall floating cable.

[0052] For example, two tension members 300 may be provided, and the two tension members 300 are provided at intervals. Of course, three or four tension members 300 may also be provided, and those skilled in the art may determine the number according to actual conditions, and no specific limitation is made here.

[0053] It should also be noted that the tension member 300 can be made of a water-blocking fiber material or a metal material, which has excellent tensile properties and improves the tensile properties of the floating cable.

[0054] In some embodiments of the present invention, Figure 1 As shown, the floating cable further includes a communication unit 400 . Two tension members 300 are provided, and the communication unit 400 is located between the two tension members 300 .

[0055] like Figure 1 As shown, the communication unit 400 can be used to transmit data. The floating sleeve 200 is coated on the outside of the communication unit 400. The communication unit 400 is made of a copper conductor 110 and a modified PVC insulation material extruded and insulated, and the outside of the PVC insulation is filled with a water-blocking powder 140. The outside of the water-blocking powder 140 is a copper wire braided shielding layer to improve the signal transmission and comprehensive performance of the floating cable.

[0056] like Figure 1 As shown, it should be noted that two tension members 300 may be provided, and the two tension members 300 are respectively provided on both sides of the communication unit 400. The tension members 300 may be symmetrically provided.

[0057] In some embodiments of the present invention, Figure 2 As shown, the cable body 100 includes a plurality of cable cores, and the cable core includes a conductor 110, a first water blocking tape 120 and an insulating layer 130. The conductor 110 is suitable for transmitting data or conducting electricity. The conductor 110 can be formed by twisting multiple strands of highly flexible single copper wires, which can improve the overall softness of the cable. Alternatively, the conductor 110 can also be made of metal materials such as aluminum, silver, gold or nickel. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0058] The first water-blocking tape 120 is coated on the outside of the conductor 110, and the outside of the conductor 110 is coated with the first water-blocking tape 120, so that the conductor 110 can be effectively prevented from being immersed in water longitudinally, so as to ensure that the cable core can also operate stably in a humid environment or in water. The first water-blocking tape 120 includes a polyester material and a water-blocking powder 140, and the water-blocking powder 140 is applied to the polyester material. By applying the water-blocking powder 140 to the polyester material, the first water-blocking tape 120 can be formed. The water-blocking powder 140 is also called a super absorbent resin or SAP (SuperAbsorbent Polymer), which is mainly composed of compounds such as sodium polyacrylate. The water-blocking powder 140 can absorb and retain a large amount of water, and its water absorption capacity can reach hundreds or even thousands of times its own weight. The water-blocking powder 140 mainly plays a water-blocking role in the cable core to prevent moisture from invading the interior of the cable core.

[0059] It should also be noted that the first water-blocking tape 120 can be formed by wrapping a polyester material and a water-blocking powder 140 material. Among them, the polyester material can be a polyester film (for example, a PET polyester film). PET polyester film is a widely used wrapping material. PET polyester film is a film material made of polyethylene terephthalate (PET) as a raw material, which is made into a thick sheet by extrusion and then biaxially stretched. PET polyester film has high mechanical strength, rigidity, hardness and toughness, and is resistant to puncture, friction, high temperature and low temperature. The water-blocking powder 140 and the PET polyester film are wrapped to form the first water-blocking tape 120, so that it can play a waterproof role, and it is also beneficial to correspondingly improve the mechanical strength, rigidity, hardness and other properties of the cable core.

[0060] Of course, the polyester material may also be other types, such as polybutylene terephthalate (PBT), polyoxyethylene acrylate (PCT) or polytrimethylene terephthalate (PTT), etc. Those skilled in the art may determine according to actual conditions, and no specific limitation is made here.

[0061] The insulating layer 130 is coated on the outside of the first water blocking tape 120 to improve the insulation performance of the cable core and prevent current leakage of the conductor 110. In addition, the cable body 100 includes multiple cable cores. By providing the insulating layer 130, multiple conductors 110 can be isolated by the insulating layer 130 to prevent current from bridging between the conductors 110, thereby causing cable operation failure. The insulating layer 130 ensures the independence of each conductor 110, so that the current can flow along a predetermined path.

[0062] The insulating layer 130 can be made of an elastomeric insulating material through an extrusion process, and the insulating layer 130 also has excellent high temperature resistance and flexibility, as well as environmental protection, halogen-free and low smoke characteristics. For example, the insulating layer 130 can be made of polyurethane elastomer, thermoplastic elastomer and other materials through an extrusion process, that is, the molten elastomer insulating material is extruded through a die using an extruder, and is tightly coated on the outside of the first water blocking tape 120 or directly coated on the outside of the conductor 110.

[0063] It should be noted that the cable body 100 is provided with multiple cable cores, that is, the cable is provided with multiple conductors 110, and each conductor 110 is insulated. The conductive capacity of the cable can be enhanced by providing multiple conductors 110. This is beneficial to improving the flexibility and mechanical strength of the cable, and can realize complex circuit connection, so that the cable body 100 can adapt to different application scenarios and improve the applicability of the cable.

[0064] The cable cores may be two, three, four or five, etc. Those skilled in the art may determine the number according to actual conditions, and no specific limitation is made here.

[0065] like Figure 2 As shown, the cable body 100 further includes a second water blocking tape 150. The second water blocking tape 150 is coated on the outside of the plurality of cable cores. The floating sleeve 200 is coated on the outside of the second water blocking tape 150. A filling layer is also filled between the second water blocking tape 150 and the plurality of cable cores.

[0066] It should be noted that the filling layer may be a water-blocking powder 140, which can effectively prevent longitudinal water immersion to improve the waterproof performance of the floating cable.

[0067] It should also be noted that the second water blocking tape 150 is coated on the outside of the plurality of cable cores, which can further improve the waterproof performance of the cable body 100. The second water blocking tape 150 and the first water blocking tape 120 may have the same structure and material.

[0068] According to an embodiment of a second aspect of the present invention, an electric device comprises the floating cable of the above embodiment.

[0069] It should be noted that the electrical equipment is connected to the floating cable of the above embodiment. When the floating cable is impacted by waves, the displacement of the floating cable is small, which can prevent the floating cable from being damaged due to excessive tension or the floating cable from pulling the electrical equipment backward.

[0070] Of course, the electrical equipment of the present application also includes at least all the beneficial effects of the above embodiments, which will not be repeated here.

[0071] It should also be noted that the electrical equipment may be an ocean exploration robot, an underwater remote-controlled drone submersible, an underwater camera, an underwater construction equipment, an underwater search and rescue robot, a pipeline detection robot, and a submersible pump. These devices are connected to other equipment, such as shore equipment, through the floating cable of the present application.

[0072] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0073] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
