The invention relates to a detection device for angle cock closing of independent wagons in the running process of rail wagons. The detection device comprises a compressed air pipeline 1, a pressure transmitter 2, a sound-light alarming device 3, a single-chip microcomputer system 4, an automatic angle cock closing restoration device 5 and a protective antitheft cover 6. The detection device is characterized in that whether an angle cock is closed or not is judged by the detection device according to a pressure value detected by the pressure difference transmitter 2, and a full-open state of the angle cock is restored and kept through the automatic angle cock closing restoration device 5. The detection device has the main advantages that the detection device is firm in installation and is prevented from falling off or being stolen during operation; judgment is accurate, and the angle cock is quickly restored to the full-open position.
