Special optical cable for optical energy transmission

Abstract

The invention discloses a special optical cable for optical energy transmission, which comprises an optical fiber body and an optical cable PE expansion sleeve arranged outside the optical fiber body. The optical cable PE expansion sleeve is provided with a spring-shaped reinforcing element, a water blocking sleeve, an insulating sleeve and a reflection sleeve which are tightly wrapped with each other in turn from the outside to the inside; and the optical cable PE expansion sleeve is tightly wrapped with the spring-shaped reinforcing element. The special optical cable for the optical energy transmission has the advantages of reasonable structural design and high transmission efficiency, and can well realize the effects of indoor illumination, warming, heating and the like.

Description

technical field [0001] The invention belongs to the technical field of optical cables, in particular to a special optical cable for optical energy transmission used for long-distance transmission of sunlight or other thermal energy light. Background technique [0002] At present, the transmission of sunlight is mainly carried by light pipes or optical fibers. These two transmission tools have the following disadvantages in use: 1. The light pipe is used to transmit the light collected by the solar concentrator to the room for lighting. In some places, due to the large diameter of the pipe, the building must be opened during use, the construction is more complicated, and it will cause great damage to the building; on the other hand, the transmission distance of the light pipe is generally short, and it cannot be used for long-distance transmission. Simultaneously, because the light guide generally adopts the processing of hard materials, the bending can only be a straight lin...

[0002] At present, the transmission of sunlight is mainly carried by light pipes or optical fibers. These two transmission tools have the following disadvantages in use: 1. The light pipe is used to transmit the light collected by the solar concentrator to the room for lighting. In some places, due to the large diameter of the pipe, the building must be opened during use, the construction is more complicated, and it will cause great damage to the building; on the other hand, the transmission distance of the light pipe is generally short, and it cannot be used for long-distance transmission. ; At the same time, because the light guide is generally made of hard materials, the bending can only be turned in a straight line, which makes large-scale application and promotion inconvenient

At present, although the application of focusing sunlight into optical cables is quite extensive, there are few studies on optical cables dedicated to optical energy transmission.
