Abstract: The present disclosure provides a cable structure with information transmission and risk early warning functions and a method of using the same. An optical fiber unit includes a communicating optical fiber unit and a sensing optical fiber unit. The communicating optical fiber unit consists of a single-mode optical fiber and a casing for protecting the optical fiber. The sensing optical fiber unit consists of a single-mode optical fiber and/or a multimode optical fiber and a casing for protecting the optical fiber. The optical fiber unit includes a single optical fiber or a plurality of optical fibers. The optical fiber in the communicating optical fiber unit and the optical fiber in the sensing optical fiber unit are packaged separately in separate casings or packaged together in a same casing. The optical fiber unit is placed between an outer sheath and a waterproof insulating layer of the power transmission unit.

Abstract: Herein disclosed is a fall-proof component for a screw, comprising: a first structure configured to act on a portion of the screw to stop the screw; and a second structure configured to be fitted and latched onto a part which is to be fixed by the screw; wherein the first structure and the second structure cooperate with each other to prevent the screw from falling and the fall-proof component is configured to be adapted to be disposed adjacent to a head of the screw in a fitted status. Also disclosed are a corresponding fall-proof screw assembly, a corresponding fall-proof screw-nut assembly, a corresponding part suitable for the fall-proof screw assembly, a corresponding combination structure and a corresponding assembly. According to the disclosure, the fall-proof component has a simple structure and a low cost and can be reusable.
