Concealed wire fire prevention automatic isolation device
The invention relates to the technical field of household fire protection, and discloses a concealed wire fire prevention automatic isolation device which comprises a ground. An installation groove isformed in the ground, an electric wire is installed in the installation groove, a plurality of annular fixed grooves are formed in the inner wall of the installation groove, a plurality of expansioncavities are formed in the top and the bottom of the installation groove, and heat conduction sheets are made of copper. The sides, close to the fixed grooves, of the expansion cavities are provided with movable grooves extending to the inner walls of the fixed grooves, and screw rods are inserted into the movable grooves. According to the concealed wire fire prevention automatic isolation device,the expansion cavities are formed in the top and the bottom of the installation groove, when a certain position of the electric wire is spontaneously ignited, the fire spreads along the electric wire, the surrounding temperature is increased, heat is conducted into the expansion cavities by the heat conduction sheets on the two sides of an ignition point, gas in the expansion cavities is thermally expanded, the screw rods are clamped by a large clamping block, and when the fire is closer to the expansion cavities, the expansion cavities absorb more and more heat.
本发明涉及家庭消防技术领域，且公开了一种暗线防火自动隔离装置，包括地面，所述地面的内部设置有安装槽，所述安装槽的内部安装有电线，所述安装槽的内壁设置有多个环形的固定槽，所述安装槽的上方和下方均开设有多个膨胀腔，导热片采用铜制成，所述膨胀腔靠近固定槽的一侧开设有延伸到固定槽内壁的活动槽，所述活动槽内插接有螺杆。该暗线防火自动隔离装置，通过在安装槽的顶部和底部开设膨胀腔，当电线的某处自燃时，火势顺着电线蔓延，导致周围温度升高，这样着火点两侧的导热片将热量导热膨胀腔内，膨胀腔内气体受热膨胀，这时螺杆被较大的卡块卡住，当火势离膨胀腔越来越近，膨胀腔吸入热量越来越多。
