Abstract

The invention discloses a lifesaving lead ejection device for a helicopter. The lifesaving lead ejection device comprises a cylinder. An arrow used for leading a carried lifesaving lead to a to-be-rescued point, and an ejection mechanism used for ejecting out the arrow are arranged in the cylinder. According to the lifesaving lead ejection device, the arrow used for leading the carried lifesaving lead is ejected out through the ejection mechanism. The structure of the device is simple, and rescuing can be effectively conducted aloft through the helicopter.

Description

technical field [0001] The invention relates to an ejection device, in particular to a lifesaving fuse ejection device for a helicopter. Background technique [0002] When a fire occurs in a high-rise building and other accidents for fire rescue, the rescue equipment is generally sent to the point to be rescued by using a ladder, and the rescue is carried out through the rescue equipment after approaching the person to be rescued. For example, the flexible pipe is sent to the point to be rescued, and the person to be rescued After going up to the ladder, he slipped down from a high altitude through the erected flexible pipeline and was rescued. [0003] At present, due to technical and other reasons, the highest rising height of the ladder is only 72 meters. If there is an accident such as a fire in a building higher than this height, and the rescuers are at a height above 72 meters, they cannot go down to the place where the ladder rises. The maximum height cannot be rescu...
