Description

Air inflation device for air film building assembly Technical Field The utility model relates to the technical field of inflation devices, in particular to an inflation device for air film building assembly. Background The air film building is a building structure system which uses special building film materials as a shell, is provided with an intelligent electromechanical device to provide positive pressure of air in the air film building, supports a building main body, and when the air film building is supported, air inflation and pressurization equipment is needed to blast the building, so that the air film is expanded, and other external forces such as wind force can be resisted by properly adjusting the air pressure in the air film. In the prior art, the air film building combined air charging device with the publication number of CN216894998U comprises a box body and a bracket arranged on the lower surface of the box body, wherein two groups of protection frames are arranged on the inner wall of the bottom of the box body, a main fan fixed on the inner wall of the box body is arranged in the front protection frame, and a standby fan fixed on the inner wall of the box body is arranged in the rear protection frame. This air film building combination aerating device, through the main fan that sets up, realized the function of device, can be with in the outside air suction air film building, improved the practicality of device, through the reserve fan of setting, realized the protection effect of device, after main fan trouble, can replace the work of main fan by reserve fan, can maintain the pressure of air film building, can avoid the condition emergence that air film building collapses, further improved the practicality of device. In the device, the air outlet pipe between the air outlet pipe of the fan body and the box body is not provided with a guide pipe and other devices, the bottom of the box body is provided with an air return grid, in the actual use process, air blown out by the fan is firstly accumulated in the box body and cannot be directly introduced into the air film building, and accumulated air can be possibly discharged from the air return grid, so that the air film building cannot be pressurized.
