Portable temporary barrier for substation

The invention relates to the technical field of barriers used for substation maintenance and discloses a portable temporary barrier for a substation. The portable temporary barrier comprises a left supporting rod, a right supporting rod, a sliding rope, a barrier body and sliding rings. The sliding rope is connected between the upper portion of the left supporting rod and the upper portion of the right supporting rod and is straightened. The upper end of the barrier body is provided with the sliding rings which penetrate the sliding rope and can slide leftwards and rightwards along the sliding rope. The left end of the barrier body is fixed to the left supporting rod. The unfolding length of the barrier body corresponds to the length of the sliding rope. The portable temporary barrier is reasonable and compact in structure and convenient to use. The sliding rings slide on the sliding rope so that the barrier body can be driven to be fast folded and unfolded; by means of the left supporting rod fixed together with the left end of the barrier body, the barrier body can be fast unfolded or folded, the defect that the portable temporary barrier is not convenient to unfold or fold and store is overcome, and the temporary barrier can be orderly, standardly and firmly arranged on the spot. Efficiency of maintainers to install the barrier is improved, meanwhile potential safety hazards are eliminated, and a basis is laid for on-site safety work.
