Infrared through-beam revolving door safety sensor device

Abstract

This utility model relates to the field of revolving door technology, specifically an infrared through-beam revolving door safety sensing device. It includes a base plate and a top plate, with two symmetrically arranged arc-shaped door frames between the base and top plates. A rotating column rotatably connects the base and top plates. The outer wall of the rotating column has three door leaf assemblies arranged in a circular array. Each door leaf assembly includes a fixed door leaf fixedly connected to the rotating column. The fixed door leaf has a U-shaped movable groove. On the left side of the inner wall of the U-shaped movable groove are two symmetrically arranged electric telescopic rods. The movable rods of the two electric telescopic rods are connected to a movable door leaf. An infrared transmitter is located at the top right side of the movable door leaf, and an infrared receiver is located at the bottom right side of the movable door leaf. This infrared through-beam revolving door safety sensing device, through the through-beam detection area formed by the infrared transmitter and receiver, can monitor obstacles between the movable door leaf and the arc-shaped door frames in real time, providing a more concentrated and directional detection range.
