extendable lifeboat

Abstract

An expandable lifeboat, comprising a boat-like body (10) and multiple unfoldable water lifesaving devices (20) placed on the boat-like body (10). The unfoldable water lifesaving devices (20) in an unfolded state are connected to the tail part of the boat-like body (10) by means of traction ropes (30) and are guided by a guiding device (11) at the tail part of the boat-like body (10); each unfoldable water lifesaving device (20) comprises a frame body (210); the frame body (210) comprises an elongate support (211) and multiple support buoys (212) provided on the elongate support (211); the elongate support (211) comprises multiple support units (2110) which are sequentially connected; each support unit (2110) comprises a first arm (2111), a first connecting rod (2112), and a second connecting rod (2113); both ends of the first connecting rod (2112) are rotatably connected to the upper end of the first arm (2111) and one end of the second connecting rod (2113), respectively; the other end of the second connecting rod (2113) is rotatably connected to the upper end of the first arm (2111) of another support unit (2110); the support buoys (212) are used for allowing the unfoldable water lifesaving device (20) to float on the water surface. The expandable lifeboat can take more passengers.

Description

technical field [0001] The invention relates to the field of emergency equipment, in particular to an expandable lifeboat. Background technique [0002] At present, large-scale water transport equipment used for passenger transport, such as passenger ships, are often equipped with lifeboats for carrying passengers on wrecked passenger ships or other water transport equipment, waiting for rescue. But, be limited to the size of existing lifeboat, the passenger number that the lifeboat on the passenger ship can carry is often less than the passenger number that passenger ship can carry, when a smaller passenger ship goes to rescue than this passenger ship passenger capacity is larger This problem is exacerbated when transporting large water equipment. [0003] Therefore, there is a need for an expandable lifeboat capable of carrying more passengers. Contents of the invention [0004] The purpose of the present invention is to provide a new expandable lifeboat capable of car...
