Description

Technical Field

[0001] The utility model relates to an outdoor photovoltaic cable which is resistant to aging and ant and rat gnawing, and belongs to the technical field of photovoltaic cables. Background Art

[0002] Photovoltaic cables are easily bitten by rats and ants during use, causing the cable core to leak or break, which not only increases the difficulty of maintenance of photovoltaic cables, but also seriously affects the service life of photovoltaic cables. In order to solve the above problems, a new technical solution is provided. Utility Model Content

[0003] The utility model aims to provide an outdoor photovoltaic cable which is resistant to aging and ant and rat gnawing, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an outdoor anti-aging and anti-ant and rat gnawing photovoltaic cable, comprising a cable core, the cable cores are close to each other, the outer side of the cable core is wrapped and connected with an optical cable tape, the outer side of the optical cable tape is covered with a PE inner sheath, the outer side of the PE inner sheath is wrapped and connected with a steel belt armor layer, the outer side of the steel belt armor layer is covered with a waterproof layer, and the outer side of the waterproof layer is covered with a PE outer sheath.

[0005] Preferably, the space between the optical cable wrapping tape and the cable core is filled with optical cable filling paste.

[0006] Preferably, protective blocks are placed equidistantly in a circular distribution between the waterproof layer and the steel belt armor layer.

[0007] Preferably, the protection block is composed of an outer medicine storage belt and an inner filling belt.

[0008] Preferably, the outer medicine storage belt is filled with ant and rodent killer drugs.

[0009] Preferably, the inner filling belt is filled with a foaming agent.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the inner filling belt of the utility model is filled with foaming agent, which can easily fill and seal the bitten area; the outer medicine storage belt is filled with ant and rodent killer, which can easily kill rats and ants; a waterproof layer is provided on the outer side of the steel belt armor layer, which can easily waterproof the photovoltaic cable; based on the above, the utility model can effectively prevent rats and ants from biting the photovoltaic cable, and effectively increase the service life of the photovoltaic cable.

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] like Figure 1-3 As shown, an outdoor anti-aging and anti-ant and rat gnawing photovoltaic cable comprises a cable core 1, the cable cores 1 are close to each other, an optical cable tape 2 is wound and connected to the outside of the cable core 1, a PE inner sheath 3 is sleeved on the outside of the optical cable tape 2, a steel belt armor layer 4 is wound and connected to the outside of the PE inner sheath 3, a waterproof layer 5 is sleeved on the outside of the steel belt armor layer 4, a PE outer sheath 6 is sleeved on the outside of the waterproof layer 5, an optical cable filling paste 7 is filled between the optical cable tape 2 and the cable core 1, protective blocks 8 are equidistantly placed in a ring-shaped distribution between the waterproof layer 5 and the steel belt armor layer 4, the protective blocks 8 are composed of an outer medicine storage tape 9 and an inner filling tape 10, the outer medicine storage tape 9 is filled with ant and rodent killer, and the inner filling tape 10 is filled with a foaming agent.

[0017] Specific usage: When rats and ants chew through the PE outer sheath 6, the waterproof layer 5, and the protective block 8 in sequence, the ant and rodent-killing medicine in the outer medicine storage belt 9 will be scattered, and the rats and ants will be poisoned after chewing; if the outer medicine storage belt 9 is chewed through and the ant and rodent-killing medicine has not taken effect, the inner filling belt 10 will be chewed, and the internal foaming agent will spray out after the inner filling belt 10 is damaged to fill and seal the chewed area.

[0018] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
