By installing equipment such as fire alarm systems and fire extinguishing systems, fire protection engineering can issue alarms in a timely manner and activate fire extinguishing facilities when a fire occurs, effectively reducing the harm of the fire to people, and at the same time enhancing the safety of buildings to protect the integrity of the buildings during a fire and reducing the risk of fire spread. Reduce the losses caused by fires.

[0003] The fire pump room is an important part of fire protection engineering. Its function is to provide power and water source for the fire protection system. The equipment and facilities in the fire pump room must be protected, and there is a high demand for its ventilation conditions. Good ventilation conditions can effectively reduce the operating temperature of the equipment and extend the service life of the equipment. At the same time, in order to ensure smooth air flow, it is necessary to ensure sufficient oxygen in the pump room through an exhaust fan and effectively remove waste gases such as smoke and odors generated by pump operation and electrical control. At present, the exhaust fan is mainly fixed and installed by multiple bolts, but the connection force between the exhaust fan and the wall is limited.
