The invention relates to the technical field of maritime rescue facilities, and discloses a lifesaving device capable of being used for medium-and-long-distance throwing. The lifesaving device comprises a connecting sleeve, the interiors of the top end and the bottom end of the connecting sleeve are each provided with a set of sealing cavities, and a transmission connecting rod is fixedly mountedat one end of a cone body; and one end of the transmission connecting rod penetrates through and extends to the outside of the connecting sleeve and is fixedly provided with an elastic rubber sleeve.According to the lifesaving device capable of being used for medium-and-long-distance throwing, due to arrangement of shear thickening liquid in inner cavities of the sealing cavities, in the throwingprocess of the lifesaving device, the shear thickening liquid can be changed into a high-viscosity liquid state, thus the phenomenon that the lifesaving device is extruded by air in the air and thenautomatically unfolded can be effectively prevented, and thus the distance and the position of a falling point of the lifesaving device during throwing are effectively controlled so as to avoid the problem that the lifesaving device deviates from the position of a drowning person too far due to the influence of wind power in the throwing process.

    本发明涉及海上救援设施技术领域,且公开了一种可用于中远距离抛投的救生装置,包括连接套筒,所述连接套筒顶端和底端的内部分别设有一组密封腔体,所述椎体的一端固定安装有传动连杆,所述传动连杆的一端贯穿并延伸至连接套筒的外部且固定安装有弹性胶筒。该可用于中远距离抛投的救生装置,对于密封腔体内腔中剪切增稠液体的设置,当该救生装置在进行抛投的过程中,其可以变成高粘度的液体状态,从而可以有效地防止该救生装置在空中受到空气的挤压而自动撑开的现象,进而有效地控制对该救生装置进行抛投时的距离及其落点的位置,以避免其在抛投的过程中因风力影响而导致其与落水者的位置偏差过远而当问题。
