Ventilation structure for constructional engineering

Abstract

The invention discloses a ventilation structure for constructional engineering. The ventilation structure comprises an environment sensor module, a ventilation structure body and an electronic controlbox, wherein the ventilation structure body comprises an electric air mask, an exhaust fan, an exhaust pipe and an exhaust fan support; the electric air mask is connected with the exhaust pipe, the exhaust fan is installed at the outlet position of the tail end of the exhaust pipe, and a controller, a motor A and a sliding resistor are integrated in the electronic control box; the environment sensor module is in signal connection with the controller, the controller is electrically connected with the motor A and indirectly controls mechanical sliding of the sliding resistor, the output of thesliding resistor is connected with a motor B and a motor C, the motor B is in driving connection with the exhaust fan, and the motor C is in driving connection with the electric air mask; and the controller also outputs a signal to be connected with a sound-light alarm module. The ventilation structure with the intelligent and automatic control exhaust fan as the main part works automatically withlow power consumption, has good effects of comprehensive ventilation, replacement ventilation and smoke prevention, and is simple in structure and easy to install.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a ventilation structure for construction engineering. Background technique [0002] Ventilation structures are usually set up indoors in construction projects. The main function is to provide the oxygen needed for human breathing, dilute indoor pollutants or odors, remove pollutants generated by indoor processes, remove indoor waste heat or humidity, and provide indoor air. The air is mainly used in buildings such as homes, businesses, hotels, and schools, mainly for comprehensive ventilation, displacement ventilation, and smoke prevention and exhaust. The traditional ventilation structure mostly uses air conditioners, which have a complex structure and consume a lot of power; the single function can only manually control the exhaust and ventilation; it is inconvenient to install and disassemble; and the use effect is not good.
