Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a floating cable. Background Technology

[0002] A cable is a device for transmitting electrical energy or signals, usually consisting of several or groups of conductors. The types of cables are also adjusted according to changes in the application environment to meet the requirements for safe operation.

[0003] When existing cables are used in water operations, marine observation, floating photovoltaic and other working environments that require long-term floating on the water surface, they often need to be positioned by auxiliary floats or positioning devices. However, this is not only time-consuming and labor-intensive, but also costly. It is also inconvenient to adjust the position of the cable floating in the water, which makes it difficult to promote its use. Therefore, we propose a floating cable. Utility Model Content

[0007] In a preferred embodiment, the present invention can be further configured such that the closed-cell foam layer is low-density polyethylene closed-cell foam.

[0008] In a preferred embodiment, the present invention can be further configured such that the water-blocking filling layer is composed of water-blocking yarn and superabsorbent resin powder.

[0009] In a preferred embodiment, the present invention can be further configured such that the buoyancy adjustment layer consists of a fixed sealed airbag and an adjustable airbag.

[0010] In a preferred embodiment, the present invention can be further configured such that the outer sheath is made of high-density polyethylene and 2-5 wt% nano-titanium dioxide composite.

[0011] In a preferred embodiment, the present invention may be further configured such that the surface of the outer sheath is coated with an anti-fouling coating.

[0012] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. This utility model provides dual-stage buoyancy through a closed-cell foam layer and a buoyancy adjustment layer, which enables the cable to have good floating ability without the need for auxiliary structures. Furthermore, by adjusting the air valve, the control within the buoyancy adjustment layer can be appropriately adjusted, thereby changing the overall buoyancy of the cable and adjusting the position of the cable in the water, making it highly practical.

[0014] 2. This utility model can greatly enhance the tensile strength of the cable through the central load-bearing component and spiral reinforcing ribs, thereby improving the cable's resistance to water flow impact. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0019] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0020] The following describes, with reference to the accompanying drawings, some embodiments of the present invention that provide a floating cable.

[0021] Combination Figure 1As shown, this utility model provides a floating cable, comprising: a central load-bearing component 1, a conductor 2, a closed-cell foam layer 3, a water-blocking filling layer 4, an inner sheath 5, a spiral reinforcing rib 6, a buoyancy adjustment layer 7, an outer sheath 8, and an adjusting valve 10. The conductor 2 is encased within the closed-cell foam layer 3, the water-blocking filling layer 4 is wrapped around the outside of the closed-cell foam layer 3, the inner sheath 5 is compressed and encased within the water-blocking filling layer 4, the spiral reinforcing rib 6 is spirally wound around the surface of the inner sheath 5, the buoyancy adjustment layer 7 is embedded inside the outer sheath 8, and the adjusting valve 10 is connected to the buoyancy adjustment layer 7. Through a multi-layer structure, it achieves a four-in-one function of "floating-waterproofing-tensile strength-corrosion resistance," giving the cable good buoyancy capability. It can be used without the need for auxiliary structures. Furthermore, by adjusting the valve 10, the control within the buoyancy adjustment layer 7 can be appropriately adjusted, thereby changing the overall buoyancy of the cable and adjusting the cable's position in the water, making it highly practical.

[0022] Furthermore, the closed-cell foam layer 3 is low-density polyethylene closed-cell foam, specifically LDPE closed-cell foam, with a density of 0.03-0.1 g / cm³ and a foaming ratio of ≥30 times, which allows it to better absorb the impact energy of water flow and protect the internal conductors.

[0023] Furthermore, the water-blocking filling layer 4 is composed of water-blocking yarn and superabsorbent resin powder. The resin powder expands when it comes into contact with water to block the gaps, and the water-blocking yarn forms a physical barrier. It is also 60% cheaper than the perfluorinated waterproof layer and is environmentally friendly and biodegradable.

[0024] Specifically, the buoyancy adjustment layer 7 consists of a fixed sealed airbag 71 and an adjustable airbag 72. The overall buoyancy of the cable can be adjusted by inflating and deflating the adjustable airbag 72. It is highly practical and can be filled with nitrogen or air.

[0025] Furthermore, the outer sheath 8 is made of high-density polyethylene and 2-5 wt% nano titanium dioxide composite. High-density polyethylene has good anti-corrosion properties, while 2-5 wt% nano titanium dioxide can scatter ultraviolet rays, increasing the aging life of the sheath to 25 years.

[0026] Furthermore, the outer sheath 8 is coated with an anti-fouling coating 9, which can reduce the amount of dirt adhering to the cable from the water, thereby avoiding increasing the weight of the cable and ensuring the safety of the cable in use.

[0027] The working principle and usage process of this utility model are as follows: First, the cable is placed in the water, and then the gas in the adjustable air bag 72 is adjusted by adjusting the air valve 10, thereby changing the position of the cable in the water.

[0028] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
