The invention discloses a rail transit shielding door projection device which comprises a projector, a first projection reflector and a second projection reflector, wherein the first projection reflector and the second projection reflector are mounted below the projector, a fixing seat and a motor are fixedly mounted on the inner wall of the bottom of the projector, a mounting hole is formed in one side of the fixing seat, and a first rotating shaft is rotatably mounted in the mounting hole. The design is reasonable, the practicality is good, and the interior of the projector can be rapidly and effectively cooled; air entering the projector can be filtered, dried and purified; electrical elements in the projector are prevented from being damaged due to damp; meanwhile, dust on a dustprooffilter screen can be cleaned up, hot air exhausted from the projector can blow away dust on the surfaces of the first projection reflector and the second projection reflector, it is guaranteed that the first projection reflector and the second projection reflector have a good refraction effect, and images projected by the projector are clear.
本发明公开了一种轨道交通屏蔽门投影装置,包括投影仪和安装在投影仪下方的第一投影反射镜和第二投影反射镜,所述投影仪的底部内壁上固定安装有固定座和电机,固定座的一侧开设有安装孔,安装孔内转动安装有第一转轴。本发明设计合理,实用性好,能够快速有效的对投影仪内部进行散热降温,能够对进入投影仪内的空气进行过滤和干燥净化,避免投影仪内部的电气元件受潮而损坏,同时可对防尘滤网上的灰尘进行清扫干净,而且从投影仪内排出的热空气可把第一投影反射镜和第二投影反射镜表面上的灰尘吹掉,保证第一投影反射镜和第二投影反射镜具有良好的折射效果,使得投影仪投放出的图像清晰。
