一种电力施工电力防火保护装置
摘要：
本发明公开了一种电力施工电力防火保护装置，包括电线、弹性变形聚拢部、接合框架和内灭火袋，电线上嵌套有弹性变形聚拢部，两个弹性变形聚拢部相对贴靠在一起且相对侧中央沿着电线相向凸起产生弹性变形，两个弹性变形聚拢部相对端之间形成中空的空腔，以便于弹性变形聚拢部恢复形变，两个弹性变形聚拢部贴靠在一起的边沿上嵌套有接合框架，将两个弹性变形聚拢部紧固在一起。本发明在电力施工阶段对电线进行防火处置，特设置一个嵌套在电线上的防火结构，在火势到达该结构后利用预先设置好的弹性形变将燃烧的电线外皮分隔掉，阻断火势在电线上的传递路线，将火势控制在有限长的一段电线上。
摘要（英）：

The invention discloses an electric power construction electric power fireproof protection device. The electric power construction electric power fireproof protection device comprises a wire, elasticdeformation gathering portions, a connection frame and an inner fire extinguishing bag. The elastic deformation gathering portions sleeve the wire, the two elastic deformation gathering portions are oppositely attached together, the centers of the opposite sides of the elastic deformation gathering portions protrude in the opposite directions along the wire to generate elastic deformation, and a cavity is formed between the opposite ends of the two elastic deformation gathering portions so that the deformation of the elastic deformation gathering portions can conveniently recover. The connection frame sleeves the edges, attached together, of the two elastic deformation gathering portions, so that the two elastic deformation gathering portions are fastened together. The electric power construction electric power fireproof protection device conducts fireproof treatment on the wire in the electric power construction stage, a fireproof structure which sleeves the wire is especially arranged, after a fire arrives at the fireproof structure, a burning wire sheath is separated by the preset elastic deformation, the transmission path of the fire on the wire is blocked, and the fire is controlled on a section, with the limited length, of the wire.
