Technical Field

[0001] The utility model relates to the technical field of umbilical cables, in particular to a tensile and compressive umbilical cable. Background Technique

[0002] In the work of underwater robots or equipment, the umbilical cable is not only used to transmit electricity and signals, but also the key to realizing real-time communication with the ground control station.

[0003] The existing umbilical cable is designed to ensure its tensile performance, which leads to excessive material stacking in the outer protective structure, resulting in a relatively large self-weight of the overall umbilical cable underwater, imposing a greater burden on the movement and operation of underwater electrical equipment, and affecting the stable operation of underwater electrical equipment. Therefore, a tensile and compressive umbilical cable is proposed to provide a set of umbilical cable structures with good tensile and compressive properties for underwater operation equipment, which can reduce the sinking gravity underwater, improve the overall tensile property of the umbilical cable, provide necessary buoyancy support for the umbilical cable, enhance the compressive performance of the cable body, and thus reduce the gravity burden on electrical equipment. Summary of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides a tensile and compressive umbilical cable to provide a set of umbilical cable structures with good tensile and compressive properties for underwater operation equipment, which can reduce the sinking gravity underwater, improve the overall tensile property of the umbilical cable, provide necessary buoyancy support for the umbilical cable, enhance the compressive performance of the cable body, and thus reduce the gravity burden on electrical equipment.

[0005] The technical solution adopted by the utility model to solve its technical problems is a tensile and compressive umbilical cable, which includes an outer protective sleeve, a buoyancy tube, an inner insulating sleeve and a wire. The buoyancy tube, the inner insulating sleeve and the wire are sequentially arranged in the outer protective sleeve. A PVC pipe sleeve for reducing the friction between the buoyancy tubes is arranged between the outer protective sleeve and the inner insulating sleeve. The buoyancy tubes are equidistantly penetrated through the wall of the PVC pipe sleeve with the wire as the center.

[0006] By adopting the above technical solution, a set of umbilical cable structures with good tensile and compressive properties can be realized for underwater operation equipment through the components composed of the outer protective sleeve, the buoyancy tube, the inner insulating sleeve and the wire.

[0007] Specifically, a PVC coating layer is arranged on the outer peripheral surface of the wire.

[0008] Specifically, the inside of the buoyancy tube is a hollow structure, and the buoyancy tube is made of elastic steel material.

[0009] By adopting the above technical solution, the arrangement of the buoyancy tube made of hollow-structured elastic steel not only provides the necessary buoyancy support for the umbilical cable, but also enhances the compressive resistance of the cable body through the use of elastic steel, which can reduce the gravity pressure of the umbilical cable on the equipment underwater, thereby reducing the gravity burden on the electrical equipment.

[0010] Specifically, the inner insulating sleeve is made of glass fiber material.

[0011] Specifically, the outer protective sleeve is composed of composite tapes woven, and the composite tape has a polyurethane plastic coating layer and stainless steel wires and nylon wires arranged inside the polyurethane plastic coating layer, and the stainless steel wires and the nylon wires are woven and connected to each other.

[0012] By adopting the above technical solution, the outer protective sleeve woven by the composite tape with a composite woven structure provides a woven structure with better toughness for the outside of the overall umbilical cable, and the stainless steel wires and nylon wires woven and connected inside the composite tape can further improve the overall tensile resistance of the umbilical cable.

[0013] Specifically, the surface of the outer protective sleeve is hot-pressed into a smooth surface by a hot press roller.

[0014] By adopting the above technical solution, the outer protective sleeve is finally processed into a smooth surface by a hot press roller to reduce the water flow resistance and improve the appearance cleanliness.

[0015] The beneficial effects of the present utility model: The assembly composed of the outer protective sleeve, the buoyancy tube, the inner insulating sleeve and the wire realizes providing a umbilical cable structure with good tensile and compressive resistance for underwater operation equipment, and can reduce the sinking gravity underwater. The outer protective sleeve woven by the composite tape with a composite woven structure provides a woven structure with better toughness for the outside of the overall umbilical cable, and the stainless steel wires and nylon wires woven and connected inside the composite tape can further improve the overall tensile resistance of the umbilical cable. The arrangement of the buoyancy tube made of hollow-structured elastic steel not only provides the necessary buoyancy support for the umbilical cable, but also enhances the compressive resistance of the cable body through the use of elastic steel, which can reduce the gravity pressure of the umbilical cable on the equipment underwater, thereby reducing the gravity burden on the electrical equipment, and solves the problem that the existing umbilical cable, in order to ensure the tensile use performance, causes the outer protective structure to have excessive materials, resulting in a large self-weight of the overall umbilical cable underwater, a large burden on the movement and operation of underwater power equipment, and affecting the operation stability of underwater power equipment.

[0024] In order to ensure the stability of the umbilical cable during use, as Figures 1-5 shown, a tensile and compressive umbilical cable according to the present utility model includes an outer protective sleeve 1, a buoyancy tube 3, an inner insulating sleeve 4 and a wire 5. The buoyancy tube 3, the inner insulating sleeve 4 and the wire 5 are sequentially arranged inside the outer protective sleeve 1. A PVC pipe sleeve 2 for reducing the friction between the buoyancy tubes 3 is arranged between the outer protective sleeve 1 and the inner insulating sleeve 4. The buoyancy tubes 3 are equidistantly arranged through the pipe wall of the PVC pipe sleeve 2 with the wire 5 as the center.

[0025] During use, through the assembly composed of the outer protective sleeve 1, the buoyancy tube 3, the inner insulating sleeve 4 and the wire 5, a set of umbilical cable structure with good tensile and compressive properties is provided for underwater operation equipment, and the sinking gravity can be reduced underwater, reducing the gravity burden on electrical equipment and ensuring the stability of the umbilical cable during use.

[0026] The present utility model further includes that a PVC plastic coating layer 6 is arranged on the outer peripheral surface of the wire 5.

[0027] In order to reduce the underwater sinking weight of the umbilical cable, by way of example, as Figure 3 shown, the present utility model further includes that the inside of the buoyancy tube 3 is a hollow structure, and the buoyancy tube 3 is made of elastic steel material.

[0028] During use, through the arrangement of the buoyancy tube 3 made of hollow structure elastic steel, not only necessary buoyancy support is provided for the umbilical cable, but also the compressive performance of the cable body is enhanced by the use of elastic steel, and the gravity pressure of the umbilical cable on the equipment underwater can be reduced, thereby reducing the gravity burden on electrical equipment.

[0029] The present utility model further includes that the inner insulating sleeve 4 is made of fiberglass material.

[0030] To improve the tensile strength, for example, as Figures 1-5 shown, the present utility model further includes that the outer protective sleeve 1 is woven and composed of composite belts 11, and the composite belt 11 has a polyurethane coated layer 103 and a stainless steel wire 101 and a nylon wire 102 arranged inside the polyurethane coated layer 103, and the stainless steel wire 101 and the nylon wire 102 are woven and connected to each other.
