Title:
MARINE HOSE AND MARINE-HOSE AIRBAG DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/167922
Kind Code:
A1
Abstract:
Provided are a marine hose and a marine-hose airbag device that, without reducing flexibility or increasing the diameter of a main hose section, make it possible to prevent the marine hose line from sinking to the bottom due to buoyancy degradation over time. Said airbag device (8) has a water-pressure sensor (9), a float sac (10) attached to the outer surface of the marine hose (1) in a folded-up state, and an injector (11) that injects air into said float sac (10). If the water-pressure sensor (9) detects a preset water pressure, the injector (11) is activated to inflate the folded-up float sac (10), and the buoyancy of the inflated float sac (10) prevents the marine hose (1) from sinking any further.
