[0002] In urban commercial complex projects, in order to consider the overall effect of the building's facade, rain shutters are centrally arranged on the outside of the ventilation openings of the air duct system. However, most existing air duct systems usually do not have effective insect prevention functions, which easily leads to insect pest problems. Although some air duct systems are equipped with insect-proof nets, these insect-proof nets are usually fixed and cannot be removed separately. Therefore, to clean the insect-proof nets, it is necessary to remove the rain shutters and manually clean them before dismantling the air ducts. The outer dimensions of the rain shutters are relatively large. During the later operation of the project, it is necessary to rent machines such as boom trucks and car cranes to clean the insect-proof nets, set up a cordon that prohibits entry, and select special operators who have received safety education and training: operators, drivers, signal workers, etc. to remove the installed rain shutters and hoist them to the ground for cleaning.
