The invention discloses an acousto-optic prompt box for an unmanned intelligent rail weighbridge, and relates to the field of acousto-optic prompt boxes, and the acousto-optic prompt box comprises a prompt box body, the top of the prompt box body is provided with an alarm lamp, one side of the prompt box body is provided with a plurality of groups of heat dissipation holes, and the other side of the prompt box body is provided with a sound amplification hole. A sound amplification hole is formed in the inner wall of the prompt box body, a loudspeaker is arranged in the sound amplification hole, a telescopic rod is installed on one side of the inner wall of the prompt box body, a blocking piece is arranged in the prompt box body and comprises baffles arranged in heat dissipation holes, and connecting rods are fixed between the multiple sets of baffles. The problem that the interior of the prompt box body is prone to being damaged due to water inflow is solved, the telescopic rods can drive the baffles to seal the heat dissipation holes, and therefore the problem that rainwater enters the interior of the prompt box body in rainy days is avoided, the problem that internal electronic elements are prone to short circuit is solved, and the service life of the prompt box is prolonged. And when the fan works, the interior of the prompt box is cooled.
本发明公开了一种无人智能轨道衡用声光提示箱,涉及声光提示箱领域,包括提示箱本体,所述提示箱本体的顶部安装有警报灯,且提示箱本体的一侧开设有多组散热孔,并且提示箱本体的另一侧开设有扩音孔,所述扩音孔的内部设置有喇叭,所述提示箱本体内壁的一侧安装有伸缩杆,所述提示箱本体的内部设置有阻挡件,所述阻挡件包括设置在散热孔内部的挡板,多组所述挡板之间固定有连接杆。本发明解决了提示箱本体内部容易进水损坏的问题,通过设置的伸缩杆能够带动挡板将散热孔进行封闭,从而避免了在下雨天时会有雨水进入到提示箱本体内部的问题,减少了内部电子元件容易短路的问题,风扇工作时会对提示箱内部进行散热。
