RECOVERY DEVICE AND RECOVERY METHOD

To provide a recovery device for surely recovering a recovery object floating on a water surface by using a flying body such as a helicopter or a drone.SOLUTION: A recovery device includes: a first rope; a sea anchor dropped in a state coupled with the first rope from a flying body capable of standing still in air; a recovery bag for recovering a recovery object floating on a water surface; a second rope coupled to the recovery bag and provided to be capable of being towed along the first rope; a locking mechanism for locking the recovery bag in a predetermined position on the first rope when the second rope coupled to the recovery bag recovering the recovery object is towed; and a recovery mechanism for recovering the recovery bag to the flying body by towing the second rope in a state with the first rope between the sea anchor and the locking mechanism stretched in between.SELECTED DRAWING: Figure 2 【課題】ヘリコプターやドローン等の飛翔体を用いて水面に浮遊する回収物を確実に回収する回収装置を提供する。【解決手段】回収装置は、第１ロープと、空中で静止可能な飛翔体から第１ロープと連結された状態で投下されるシーアンカーと、水面に浮遊する回収物を回収する回収袋と、回収袋と結ばれ、第１ロープに沿って牽引可能に設けられた第２ロープと、回収物を回収した回収袋と結ばれた第２ロープを牽引した際に第１ロープの所定位置で回収袋を係止する係止機構と、シーアンカーと係止機構との間の第１ロープを張架した状態で第２ロープを牽引して回収袋を飛翔体に回収する回収機構とを備える。【選択図】図２
