Among them, the "real-time detection device for rail transit obstacles" disclosed by the announcement number "CN214585995U" has solved the current laser detection method. Most of the devices are based on static non-real-time devices. This technical method cannot meet the real-time detection of the entire track area, or although the real-time detection of the entire track area is adopted, there are still many detection blind spots, which pose a great safety hazard and need to be further improved. After further search, it is found that the announcement number is "CN21142679 1U" disclosed "an obstacle detection device for rail transit detection", which, through a specific technical structure setting, effectively solves the problem that the detection of obstacles is generally achieved by a walking trolley provided with ultrasonic detection equipment, but in the prior art, it is not convenient to detect and clean easy-to-clean and stubborn obstacles, and it is not convenient to detect stubborn obstacles after the movable pebbles and other debris are cleaned. However, in actual use, rail transit with similar structures still has many defects, such as: the current detection device can only clear objects on the track surface, the oil on the track surface is difficult to clean, and the vehicle is prone to slipping. At the same time, the detection device does not have a good early warning system, and the front staff cannot be notified in advance during operation, which leads to potential safety hazards. Therefore, it is necessary to design a rail transit obstacle detection device. Utility Model Content
