Embodiment 1

[0032] like figure 1 and figure 2 An anti-gnawing photovoltaic cable shown includes a cable main body 1 arranged at the center of the cable and an outer sheath 6 that is covered and located on the surface of the cable; The rotating ring body 10 includes a plurality of annular sheathing layers 3 that are sheathed one by one along the length of the cable body 1 , and each adjacent two annular sheathing layers 3 are attached to each other.

[0033] In this embodiment, as figure 2 As shown, elastic adhesive layers 8 are fixed on both end surfaces of each annular sleeve layer 3 . Based on the fact that each ring-shaped jacket layer 3 can rotate independently, the elastic glue layer 8 can be compressed, which can promote the bendability of the rotating ring body 10, so that the bendability of the cable is not affected, and the arrangement of the cable is facilitated.

[0034] In this embodiment, as figure 1 and figure 2 As shown, the outer side of the cable body 1 is covered...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is:

[0040] In this embodiment, as image 3 and Figure 4 As shown, the rotating ring body 10 also includes a plurality of balls 4 embedded in the outer surface of the annular sleeve layer 3. The annular sleeve layer 3 is evenly provided with universal grooves 5 for embedding the balls 4. A rotatable ball 4 is embedded in the groove 5 , and less than half of the ball 4 is located outside the universal groove 5 . When the ball 4 is bitten, it can rotate in the universal groove 5 and is not easy to be bitten successfully, so that the anti-bite function of the cable can be enhanced.

[0041] Further, the materials of the balls 4 and the annular sleeve layer 3 are both flame-retardant plastics. The flame-retardant plastic is light in weight, suitable for use in cables, and has flame-retardant properties, which can enhance the flame-retardant function of cables.

[0042] Further, as image 3 and Figure 4 As show...

Embodiment 3

[0048] The difference between this embodiment and Embodiment 2 is:

[0049] In this embodiment, as Figure 5 As shown, the outer side of the cable body 1 is provided with an inner sheath 2, and the materials of the inner sheath 2 and the outer sheath 6 are both added with materials with a pungent odor. The inner sheath 2 can enhance the protection function of the main body of the cable, and adding materials with irritating odors can drive away animals such as snakes, insects, rats, ants, etc., such as mint, aromatherapy, mothballs, etc. odor, which can enhance the anti-rat bite performance of the cable.

[0050] Further, as Figure 5 and Image 6 As shown, the outer sheath 6 includes an inner sheath layer 61 and an outer sheath layer 62 covering the outer side of the inner sheath layer 61. One side of the inner sheath layer 61 is cut to form a crack, and the outer sheath layer 62 corresponds to the inner sheath layer 61. The side opposite to the side where the crack is loc...

Abstract

The invention discloses an anti-biting photovoltaic cable, which belongs to the field of cables, and comprises a cable body arranged at the center of the cable and an outer sheath covering the surface of the cable; The outer rotating ring body, the rotating ring body includes an annular sleeve layer and a number of balls embedded on the outer surface of the annular sleeve layer, and universal grooves for ball embedding are evenly opened on the annular sleeve layer. A rotatable ball is embedded in the groove, and less than half of the ball is located outside the universal groove, and a tip facing outward is fixed on the annular sleeve layer between each adjacent two universal grooves. pointed protrusions. The cable provided by the invention can achieve a better anti-gnawing function, does not need to be protected by a corresponding protective sleeve during application, does not affect the bendable performance of the cable, and can also improve the compressive performance of the cable.

Description

technical field [0001] The invention relates to the field of cables, in particular to an anti-gnawing photovoltaic cable. Background technique [0002] The development of solar energy has shown a blowout development in recent years. As of the end of 2010, the installed capacity of solar photovoltaic power generation in my country has reached 893MW, ranking seventh in the world. The state also provides support for photovoltaic construction projects. Photovoltaic power generation has driven the rapid development of related products, such as photovoltaic cables. Usually, the low-voltage DC power generated by photovoltaic power generation needs to be converted into AC power, and the connecting cable between the photovoltaic cell and the AC-DC inverter is the photovoltaic cable. [0003] The application environment of photovoltaic cables is different, so the laying place should be considered in the design, such as the prevention of small animals such as mice. However, the exis...
