Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a fully sealed flexible cable body for photovoltaics. Background Art

[0002] In the current flexible photovoltaic support structure system, the flexible photovoltaic cables used are divided into load-bearing cables and component cables. The load-bearing cables are mainly set between two adjacent supporting steel frames. The cable body is connected to the photovoltaic panel tripod to bear the weight of the photovoltaic panel. The cable length is about 30 to 40 meters. The component cable is set between the head and tail supporting steel frames. Generally, two cables are set, one high and one low. The cable body is connected to the lower plane of the photovoltaic panel through a steel hoop, which is used to tension the installation angle of the photovoltaic panel. The cable length is about 100 to 600 meters.

[0003] Existing flexible cables mostly use exposed steel strands or steel wire bundles. Although they have certain strength and toughness, they are easily affected by corrosion, oxidation and wear in outdoor environments, resulting in degradation of cable performance and even safety accidents. Therefore, we propose a fully sealed flexible cable for photovoltaics. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a fully sealed flexible cable body for photovoltaic use, comprising:

[0006] An extrusion anchor, an extrusion spring, a flexible cable, microcrystalline wax, an anti-ultraviolet cable sheath and a pad. The pad is fixedly mounted on the outer surface of the extrusion anchor, the extrusion spring is mounted inside the extrusion anchor, the anti-ultraviolet cable sheath is fixedly sleeved on the outer surface of the flexible cable through microcrystalline wax, one end of the flexible cable is mounted inside the extrusion anchor, and the flexible cable is located inside the extrusion spring.

[0008] Preferably, the anti-ultraviolet cable sheath is located inside the extrusion anchor, and the outer surface of the anti-ultraviolet cable sheath is in contact with the inner wall of the extrusion anchor.

[0009] Preferably, the flexible cable 3 is composed of a plurality of epoxy-coated steel strands.

[0010] Preferably, the flexible cable is formed by twisting together single-filament epoxy-coated prestressed steel strand, prestressed hot-dip galvanized steel strand, prestressed concrete steel strand, epoxy-coated seven-filament prestressed steel strand and hot-dip galvanized aluminum alloy steel strand.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The photovoltaic fully sealed flexible cable body is supported by multiple epoxy coated steel strands that are intertwined, making the flexible cable more corrosion-resistant and having excellent mechanical and weather resistance. The anti-ultraviolet cable sheath plus microcrystalline wax can completely seal the inside of the flexible cable, thereby forming a fully sealed protective layer on the outside of the flexible cable, which can effectively prevent the flexible cable from being eroded and worn by the external environment.
