[0002] Environmental safety during confined space operations is the primary factor in whether a project can be successfully completed. During confined space operations, some harmful gases or insufficient oxygen content are often produced. When the harmful gas content exceeds the standard or the oxygen content is insufficient, it often causes certain harm to the operators. At present, the more commonly used method is to use ventilation to deal with it. There are two types of ventilation methods: natural ventilation and forced ventilation. Natural ventilation has a long ventilation cycle and poor ventilation effect, and delays the progress of the operation. It is time-consuming and labor-intensive. Forced ventilation cannot guarantee the power supply of equipment in remote areas or harsh environments. It uses generators for power supply. The equipment is bulky and inconvenient to carry. At the same time, it needs to be aligned with the connected ventilation pipes during ventilation. Some ventilation equipment is not convenient to adjust, so it is less practical.
