The utility model relates to the technical field of wind pressure detection, in particular to a device for detecting the wind pressure of a coal mine ventilator. The device has the advantages that the center column is arranged, the guide sleeves are fixedly connected to the two sides of the center column, the adjusting nuts are rotationally connected to one ends of the guide sleeves, the guide plates are slidably connected to the inner walls of the guide sleeves, and the telescopic screws are fixedly connected to the centers of one side faces of the guide plates; a damping pad is fixedly connected to the end, away from the guide plate, of the telescopic screw rod, so that a user adjusts the telescopic screw rod by rotating the adjusting nut, and therefore the damping pad can fix the inner wall of the pipeline to adapt to pipelines with different diameters within a certain range; the rotating length of the guide sliding rail can be adjusted to the position matched with the radius of the pipeline, so that the w
