Description

Technical Field

[0001] The invention relates to the technical field of cable manufacturing, and in particular to a high-performance aluminum-magnesium-silicon alloy conductor waterproof cable. Background Art

[0002] Cable is one of the indispensable materials in the process of power transmission. With the continuous development of technical conditions, the requirements for cables in various industries are getting higher and higher. Among the electrical components of marine equipment, the waterproof performance of cables is crucial to the safe operation of equipment. In related technologies, in the humid marine environment, cables are provided with a waterproof layer outside the cable core to prevent water from penetrating, thereby extending the service life of the cable.

[0003] For example, a waterproof cable disclosed in Chinese patent CN111446039B has a cable core, an insulating layer, a first waterproof layer and a second waterproof layer which are sequentially nested together from the inside to the outside. At the same time, the radial speed of water flowing on the outer wall and the inner wall of the second waterproof layer can be effectively reduced through the first spiral groove and the second spiral groove. Although the rate of water infiltration into the cable is reduced, the service life of the cable is effectively extended, but the cable has no protection capability, resulting in the defect of poor waterproof effect of the cable.

[0004] At the same time, in the prior art, the preparation process of the cable has the following defects:

[0005] 1. Invasive detection methods: Existing technologies such as scanning electron microscopy (SEM) and transmission electron microscopy (TEM) provide high-resolution microstructure images, but these methods are invasive. They usually require significant pre-processing of the sample, such as slicing, coating, etc., which will destroy the sample and are not suitable for real-time monitoring in continuous production processes.

[0006] 2. Offline detection limitations: Most existing methods are offline detection and cannot provide immediate production line feedback. This limits the dynamic adjustment capability of the production process, reduces production efficiency and may lead to a higher rate of defective products.

[0007] 3. The waterproof cable cannot be actively protected, resulting in poor waterproof effect of the waterproof cable;

[0008] The present invention is made to solve the common problems in this field, such as lack of detection means, insufficient quality assessment ability, lack of active protection of cables, poor intelligence, weak waterproof performance of cables and insufficient preparation ability.

[0208] k2=0.3;

[0209] k3=0.1;

[0210] 2) Standard power cable (faster speed, slightly more tolerant to fluctuations, but speed changes still need to be monitored):

[0211] Although the pulling speed stability of power cables is important, its impact on product performance is slightly lower than that of communication cables.

[0212] k1=0.3;

[0213] k2=0.4;

[0214] k3=0.3;

[0215] 3) High temperature resistant special cables (such as high temperature resistant or special environment cables):

[0216] Special cables may be used in extreme environments, and the pulling speed must be controlled very strictly to ensure structural stability:

[0217] k1=0.5;

[0218] k2=0.2;

[0219] k3=0.3;

[0220] In short, the specific values ​​of the adjustment factors k1, k2, and k3 need to be determined by the operator or the system according to specific circumstances. This is a technical means well known to those skilled in the art. Those skilled in the art can refer to relevant technical manuals to learn about the technology, so they will not be described one by one in this embodiment.

[0221] The wrapping evaluation unit obtains the pulling index Pull and calculates the wrapping speed Rolling according to the following formula:

[0222] Rolling=v t (1+τ(Pull-1))

[0223] In the formula, v t is the current pulling speed, Pull is the pulling index, which comprehensively considers the volatility and stability of the pulling speed, and τ is the speed adjustment coefficient, which is used to adjust the influence of the pulling index on the wrapping speed;

[0224] In this embodiment, an example of a value of the speed adjustment coefficient τ is provided, specifically:

[0225] 1) General cable production, suitable for most standard cable production, ensuring moderate response flexibility, then τ = 0.1;

[0226] 2) Cable production with high precision requirements, that is, for cables that require higher precision control, such as data transmission cables, the adjustment coefficient is increased to respond faster to changes in pulling speed, then τ = 0.15;

[0227] 3) Special cable production, that is, when producing special cables, such as high temperature resistant or chemical corrosion resistant cables, the adjustment coefficient is reduced to maintain a high degree of stability in the production process, then τ = 0.05;

[0228] In short, the specific value of the speed adjustment coefficient τ needs to be determined by the operator or the system according to the specific situation. This is a technical means well known to those skilled in the art. Those skilled in the art can refer to relevant technical manuals to learn about the technology, so it will not be described in detail in this embodiment.

[0229] Through the mutual cooperation between the pulling module and the wrapping module, the wrapping module can take into account the pulling speed of the pulling module during the wrapping process, thereby improving the preparation capacity and preparation accuracy of the entire manufacturing system, and ensuring that the entire system has the advantages of precise quality monitoring, strong control ability, good quality assessment ability, reliable detection means and high intelligence.
