Cable trench firewall plugging device
The invention relates to the technical field of power equipment, in particular to a cable trench firewall plugging device which comprises a cable trench, a firewall and a plugging device body, the firewall is arranged in the cable trench and provided with a water drainage opening, the plugging device body is arranged in the water drainage opening, and a coarse filtering assembly and a fine filtering assembly are arranged in the plugging device body. The two fine filtering assemblies are symmetrically arranged along the central axis of the plugging device to form a protection area; the coarse filtering assemblies and the fine filtering assemblies are arranged to conduct filtering in a grading mode, large-size sundries and small animals are filtered through the coarse filtering assemblies, small-size sundries and small animals are filtered through the fine filtering assemblies, blocking is effectively prevented, the small animals can be effectively protected, the number of the fine filtering assemblies is two, and the two fine filtering assemblies are symmetrically arranged along the central axis of the blocking device. A protection area is formed, and small animals can be trapped in the protection area after penetrating through the coarse filter screen, so that the small animals are prevented from crossing the firewall to damage equipment.
发明涉及电力设备技术领域，尤其是一种电缆沟防火墙封堵装置，包括电缆沟、防火墙以及封堵装置，所述防火墙设置于电缆沟内且防火墙上开设有排水口，所述封堵装置设置于排水口内，所述封堵装置内设有粗过滤组件以及细过滤组件，所述细过滤组件为两个，沿封堵装置的中轴线对称设置，形成防护区；通过设置粗过滤组件和细过滤组件分级进行过滤，通过粗过滤组件过滤大体积杂物和小动物，通过细过滤组件过滤小体积杂物和小动物，有效防止堵塞且能够有效对小动物进行防护，细过滤组件为两个，沿封堵装置的中轴线对称设置，形成防护区，当小动物穿过粗过滤网后会被困在防护区内，防止其越过防火墙对设备造成损伤。
