The invention belongs to the field of fire-fighting equipment, and particularly relates to a fire-fighting accident broadcasting device for fire fighting, which comprises a vehicle body, a through hole is formed in the top of the vehicle body, a lifting plate is arranged in an inner cavity of the vehicle body, vertical plates are fixed on two sides of the top of the inner cavity of the vehicle body, and first limiting chutes are formed in the inner walls of the vertical plates; a lead screw motor is fixedly mounted at the top of an inner cavity of the first limiting sliding groove. Through the first damper arranged between the lead screw sliding block and the connecting rod and the second damper arranged between the top of the lifting plate and the adjusting mechanism, the broadcast device body can comprehensively relieve impact force on the front side and the rear side during braking and vibration generated by uneven road surfaces in the rapid running process of a vehicle, and the service life of the broadcast device body is prolonged. Therefore, the broadcasting device body is effectively protected, the impact of internal stress on the broadcasting device body is effectively relieved, and the service life of the device is prolonged.
本发明属于消防设备领域,具体为一种消防用消防事故广播装置,包括车体,所述车体的顶部开设有通孔,所述车体的内腔置有升降板,所述车体的内腔顶部两侧均固定有竖板,所述竖板的内壁开设有第一限位滑槽,所述第一限位滑槽的内腔顶部固定安装有丝杆电机。本发明通过丝杆滑块和连接杆之间设置的第一阻尼器,同时升降板顶部和调节机构之间设置的第二阻尼器,从而能够使得广播装置本体在车辆快速行驶的过程中,对刹车时前后侧冲击力以及路面不平产生的振动进行全方位的缓解,从而有效的保护了广播装置本体,对其受到内应力的冲击进行有效的缓解,进而延长了装置的使用寿命。
