Description

Technical Field

[0001] The utility model belongs to the field of buoyancy detection cables, and particularly relates to a tensile-resistant and super five-category buoyancy detection cable. Background Art

[0002] With the continuous development of underwater communication technology, the requirements for cables used in underwater operation systems are further improved. The cable is required to have a small outer diameter, a density close to that of water, and be able to suspend in water. Therefore, a cable suitable for underwater operation systems is needed. Summary of the Invention

[0003] In order to solve the above technical problems, the utility model provides a tensile-resistant and super five-category buoyancy detection cable.

[0004] A tensile-resistant and super five-category buoyancy detection cable includes a cable core, a shielding layer, and an outer sheath; wherein, a shielding layer is extruded and wrapped outside the cable core; and an outer sheath is wrapped outside the shielding layer.

[0005] Further, the cable core includes a power line, a super five-category network cable, non-woven fabric, and aramid filling. The super five-category network cable is wrapped with non-woven fabric, and aramid filling is filled in the space between the super five-category network cable and the power line.

[0006] Further, the super five-category network cable adopts a pairwise twisted structure.

[0007] Further, the shielding layer adopts a structure of interlaced braiding of tinned copper wires and aramid filaments.

[0008] Further, the outer sheath adopts a TPU foamed sheath.

[0009] Advantageous Technical Effects of the Utility Model

[0010] 1. The cable adopts a super five-category network cable with a pairwise twisted structure, which increases the signal transmission distance to cooperate with the video line for transmission. The twist pitches of different signal line loops are different, thus greatly reducing the crosstalk interference generated between insulated wire pairs during signal transmission.

[0011] 2. The shielding layer adopts a structure of interlaced braiding of tinned copper wires and aramid filaments. While ensuring the shielding performance, the high flexibility of aramid improves the flexibility, bendability, and tensile resistance of the cable, ensuring that the signal transmission is not interfered, and at the same time enabling the cable to be bent and twisted frequently back and forth without breaking.

[0012] 3. The outer sheath adopts a TPU foam sheath. For traditional buoyancy cables to reduce their own weight, polyethylene with a density less than that of water is usually selected as the sheath layer material. However, due to the poor bending performance of polyethylene, it is prone to cracking after bending, which is not conducive to mobile operations. At the same time, considering the requirement of underwater environmental corrosion resistance, we use a polyester-based elastomer with the same density less than that of water as the waterproof layer material, and this material has better flexibility than polyethylene. Polyurethane material with good corrosion resistance, flexibility, tensile strength, and elongation at break is used as the outer sheath.

[0013] 4. The utility model can transmit the power control signal sent by the water-based facility to the underwater device, control the underwater device and make it work properly; at the same time, it can also transmit the information collected by the underwater device to the water-based facility for analysis and processing through video or signals, etc.; regardless of whether the water-based facility is moving or not, the underwater device can be freely bent and retracted according to the operation needs; it can reduce the resistance generated during the retraction and navigation due to the self-weight of the instruments and cables, and save the power consumption.

[0016] The following is a detailed description of the specific embodiments, structures, features, and their effects provided according to the utility model in combination with the accompanying drawings and preferred embodiments.

[0017] A tensile and Category 5e buoyancy detection cable includes a cable core, a shielding layer 5, and an outer sheath 6; among them, a shielding layer 5 is extruded and wrapped outside the cable core; an outer sheath 6 is wrapped outside the shielding layer.

[0018] Furthermore, the cable core includes a power cord 2, a Category 5e network cable 3, a non-woven fabric 4, and an aramid filling 1. The Category 5e network cable 3 is wrapped with a non-woven fabric 4, and the aramid filling 1 is filled in the space between the Category 5e network cable 3 and the power cord 2.

[0019] Furthermore, the Category 5e network cable 3 adopts a pairwise twisted structure.

[0020] Furthermore, the shielding layer 5 adopts a structure of interlaced braiding of tinned copper wires and aramid filaments.

[0021] Furthermore, the outer sheath 6 adopts a TPU foam sheath.

[0022] The beneficial technical effects of the utility model:

[0023] 1. This cable uses a Category 5e network cable and has a structure of twisting two wires together in pairs, which increases the signal transmission distance to cooperate with the video cable for transmission. The twist pitches of different signal wire loops are different, thus greatly reducing the crosstalk interference generated between insulated wire pairs during signal transmission.

[0024] 2. The shielding layer adopts a structure of interlaced braiding of tinned copper wire and aramid fiber. While ensuring the shielding performance, the high flexibility of aramid improves the flexibility, bendability and tensile strength of the cable, ensuring that the signal transmission is not interfered, and at the same time enabling the cable to be bent and twisted frequently back and forth without breaking.

[0025] 3. The outer sheath uses a TPU foam sheath. For traditional buoyancy cables to reduce their own weight, polyethylene with a density less than that of water is usually selected as the sheath layer material. Since polyethylene has poor bending performance and is prone to cracking after bending, it is not conducive to mobile operations. At the same time, considering the requirements of underwater environmental corrosion resistance, we use a polyester-based elastomer with the same density less than that of water as the waterproof layer material, and this material has better flexibility than polyethylene. Polyurethane material with good corrosion resistance, flexibility, tensile strength and elongation at break is used as the outer sheath.

[0026] 4. This utility model can transmit the power control signal emitted by the water-based facility to the underwater device, control the underwater device and make it work properly; at the same time, it can also transmit the information collected by the underwater device to the water-based facility for analysis and processing through video or signal and other means. Whether the water-based facility is moving or not, the underwater device can be freely bent, retracted and released according to the operation needs. The density of this cable is basically close to the water density of the use environment, and it can stay at any position in the water, and can reduce the resistance generated during the retraction, release and navigation due to the self-weight of the instrument and the cable, saving the power consumption.

[0027] The above has described a detailed embodiment of this utility model, but the content described is only the preferred embodiment of this utility model and cannot be considered as used to limit the scope of implementation of this utility model. All equal changes and improvements made according to the scope of application of this utility model should fall within the scope covered by the patent of this utility model.
