Coal mine underground fire isolating device
The invention belongs to the technical field of mining equipment, and discloses an underground coal mine fire partition device which comprises a sealing plate, the sealing plate is in a vertically-placed semicircular plate shape, a sliding groove shaft is fixed to the horizontal plane of the lower end of the sealing plate, and the central axis of the sliding groove shaft is perpendicular to the central axis of the circle where the sealing plate is located. The lower end of the sliding groove shaft is connected with a pair of symmetrically-arranged firewalls in a sliding and clamping mode, and the firewalls can slide in the axis direction of the sliding groove shaft. The fireproof partition is divided into a first-stage fireproof part and a second-stage fireproof part; in the first-stage fire prevention, fire spreading is cut off through a first fireproof curtain, and people who do not evacuate in time can conveniently evacuate after opening the first fireproof curtain; after workers in the mine completely evacuate, the two fireproof doors are closed to carry out a second-stage fireproof process, fire spreading is thoroughly isolated, and explosive shock waves generated by a fire can be blocked; the defects existing in a fire partition device in the prior art are overcome, the situation that a fireproof door is difficult to open after being closed is avoided, and the purpose of facilitating escape of personnel in a mine is achieved.
本发明属于矿用设备技术领域，公开一种煤矿井下火灾隔断装置，包括密封板，密封板呈竖直放置的半圆形板状，密封板下端水平平面固定有滑槽轴，且滑槽轴中心轴线与密封板所在圆的中心轴线呈垂直放置状态，滑槽轴下端滑动卡接有一对对称放置的防火墙，且防火墙均可沿滑槽轴轴线方向滑动；将防火隔断分为第一级防火和第二级防火；第一级防火通过第一防火帘隔断火势的蔓延，且便于未及时撤离人员掀开第一防火帘后撤离；待矿井内工作人员完全撤离后，关闭两防火门进行第二级防火过程，彻底隔绝火势蔓延，且可阻挡因火灾产生的爆炸冲击波；解决了现有技术中火灾隔断装置中存在的弊端，避免因防火门关闭后难以打开，实现便于矿井内人员逃生的目的。
