Pocket deployment device for isolating e.g. fuel tank, has semi-rigid bars distributed regularly on periphery of hoops, and flexible connection pieces fixing bars on hoops and pocket, where enclosure has opening to allow passage of air

摘要

#CMT# #/CMT# The device has two semi-rigid hoops (1) separated by three semi-rigid bars (2), where the bars are distributed regularly on a periphery of the hoops. Flexible connection pieces (3) fix the bars on the hoops and a pocket (4). An assembly of the hoops and bars is placed inside an enclosure. The enclosure has an opening for allowing the passage of air and man. The connection pieces provide a pivot to permit the rotation of the bars around a surface of the hoops. #CMT#USE : #/CMT# Used for deploying a pocket inside a reservoir e.g. fuel tank, to isolate the reservoir from content e.g. fuel, and to double a wall of the fuel tank to reuse the water in a storage tank. #CMT#ADVANTAGE : #/CMT# The arrangement of the semi-rigid bars and the hoops permits to elastically extend the pocket, thus enabling the pocket to accept elastic deformations to pass through the orifice more narrower than a volume of the container without requiring a manual intervention for deployment of the pocket. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a pocket deployment device. 1 : Hoops 2 : Bars 3 : Connection pieces 4 : Pocket.
