AI Technical Summary
Existing outdoor electrical equipment protective fences are ineffective at preventing climbing and are susceptible to wind and sand erosion in dusty areas, resulting in a shortened service life.
A protective fence consisting of posts, railings, protective netting, and sand barriers has been designed. Anti-climbing components are installed on the top of the railings, and sand barriers are installed at the bottom. The protective netting and sand barriers are used to prevent climbing and sand intrusion, respectively. Ventilation holes are provided on the surface of the railings to block sand. The anti-climbing components increase the difficulty of climbing through the arc-shaped cover and rotating cylinder, and the sand barriers adopt an arc-shaped design to reduce wind resistance.
It effectively prevents climbers from climbing, reduces the risk of equipment theft, prevents sand and dust erosion, extends the service life of the equipment, and prevents damage by small animals.
