Abstract

The invention discloses an on-site fast-assembly fence unit, system and method, and relates to the technical field of electric power engineering safety protection. Comprising a single fence body (1), a T-shaped support (2) capable of being movably stored and a pressing type connecting device (3). The T-shaped support (2) is a foldable connecting rod mechanism composed of a T-shaped support vertical plate (201), a plurality of sets of movable connecting plates and pin shafts, and the T-shaped support (2) can be pulled downwards to be unfolded into a T-shaped supporting structure perpendicular to the fence body or can be stored in a longitudinal groove in the side face of the fence body after being folded. The connecting device (3) is arranged at the end of the fence body and composed of a buckle plate (301), a clamping column (302), a spring guide column (303) and a rotary pin shaft (305), and the multiple fence bodies can be rapidly connected and unlocked by pressing the spring guide column. In addition, the invention further comprises a fence system formed by connecting a plurality of portable fence units end to end, and a corresponding use method (fence connection and T-shaped support unfolding / folding steps). The device does not need to be embedded or fixed through bolts, meets the temporary operation requirements of the pumped storage power station, and has portability, quick installation and reusability.
