The invention belongs to the field of speed measurement equipment, and particularly relates to a radio wave-based highway automatic speed measurement device, which comprises a protection box, the bottom end of the protection box is fixedly provided with a support frame, the inner side of the protection box is fixedly provided with a radio wave speed measurement instrument body, and the radio wave speed measurement instrument body is matched with the arrangement of an isolation plate and a rotating fan. When a vehicle rolls up storm waves or blows strong wind on the head, airflow can pass through the blast cover and blow the rotating fan to rotate by matching with the arrangement that the two ends of the blast cover are transparent, the isolation plate is driven to move up and down through the linkage assembly, and the isolation plate rubs with the sweeping rolling wheels in the up-down moving process, so that the sweeping effect is improved. And meanwhile, in cooperation with vibration generated by the isolation plate in the moving process, dust on the outer side of the isolation plate can be effectively removed, then the self-cleaning function of the device is achieved, and it is guaranteed that the device can conduct precise speed measurement work for a long time in the severe environment.
本发明属于属于测速设备领域,具体的说是一种基于无线电波的高速公路自动测速设备,包括保护箱,所述保护箱的底端固定安装有支撑架,所述保护箱的内侧固定安装有无线电波测速仪本体,配合隔离板和旋转扇的设置,当车辆经过卷起风浪或者迎面吹来大风时,配合鼓风罩两头通透的设置,可以让气流通过鼓风罩,并吹动旋转扇转动,通过联动组件带动隔离板进行上下移动,隔离板在上下移动过程中,会和清扫滚轮进行摩擦,同时配合移动过程中隔离板产生的震动,可以有效的将隔离板外侧的尘土给去除,进而实现了装置的自清洁功能,保证了装置在恶劣环境下也可以长期进行精准的测速工作。
