Ventilation construction structure based on fresh air system

The ventilation construction structure based on the fresh air system comprises a fastening clamp, the fastening clamp is provided with a containing cavity used for containing a pipeline port, and the fastening clamp limits the transverse degree of freedom and the vertical degree of freedom of the fastening clamp on the wall face of a pipeline through a lock; a servo motor is arranged above the fastening clamp, an output shaft of the servo motor is connected with a rope, the free end of the rope is connected with a maintenance platform, and a locking mechanism used for locking the moving rope is installed on the containing cavity; through combination of a locking mechanism for the rope and a ventilation structure, the problems that the rope suddenly descends easily due to accidental damage of the servo motor, and workers are lack of ventilation deeply in the industrial pipeline, and oxygen deficit is easily caused are effectively solved. 本申请公开一种基于新风系统的通风施工结构，包括紧固夹，紧固夹上配置有用于容纳管道端口的容纳腔，且紧固夹通过锁具限制紧固夹在管道壁面上发生横向、竖向
