Description

Crewman life saving equipment that falls into water

Technical Field

The invention belongs to the field of auxiliary equipment of ships, and particularly relates to a crew drowning lifesaving device.

Background

A ship generally refers to a structure that is installed in rivers, lakes, and seas to allow vehicles, pedestrians, and the like to smoothly pass through the structure. In order to adapt to the modern high-speed developed traffic industry, ships are also extended to be buildings which span mountain stream, unfavorable geology or meet other traffic needs and are erected to enable the ships to pass more conveniently. When people accidentally fall from a ship or fall into water in case of flood disasters, people are very dangerous, and life buoys are often arranged on the ship for the safety of sailors. The lifebuoy is a kind of water life-saving equipment, and is usually made of cork, foamed plastic or other light materials with a small specific gravity, and canvas, plastic and the like are wrapped outside the lifebuoy. The life ring for swimming practice can also be made of rubber, filled with air and also called as a rubber ring. The color of the outer surface of the life buoy is orange red, and the life buoy has no color difference. The surface of the life buoy should have no unevenness and no cracking. And reverse reflective belts with the width of 50 mm are adhered around the four positions with equal intervals along the perimeter of the life buoy. The life buoy should be resistant to high and low temperatures without shrinkage, cracking, expansion and decomposition. After the life buoy is thrown from a specified height, the life buoy should not crack or break. The life buoy should be oil resistant and free of shrinkage, cracking, expansion and decomposition. The life buoy should be fire resistant and should not burn or continue to melt after passing a fire. The life buoy should be able to support 14.5kg of iron blocks to float continuously in fresh water for 24 hours. The life buoy should be able to withstand a weight of 90kg for 30min without rupture and permanent deformation in the freely suspended condition. For a life buoy equipped with a self-generating smoke signal and a speed-throwing device attached to a self-illuminating floating light, the device should be triggered when released. When the lifebuoy is freely suspended, it should be capable of bearing a weight of ninety kilograms in thirty minutes, and during this time period the lifebuoy will not break, nor deform.

However, the life buoy has a single function, and is only used by people and plays a role in lifesaving when people fall into water, but in the actual sailing process, the use frequency of the life buoy is not particularly high, if the life buoy is only placed on a ship and is not utilized, resources are wasted, the existing ship personnel need to descend water to rescue after falling into water, but the life buoy can be thrown away by the people falling into water before rescue, but the manpower is limited, and under the influence of various factors on the water surface, the life safety and health of the people falling into water can not be accurately and powerfully thrown towards the people falling into water, and therefore the life safety and health of the people falling into water can be damaged to a certain extent, and a ship falling-into-water rescue mechanical device needs to be invented urgently. The presently disclosed lifebuoy for ship rescue, such as chinese invention patent, application No. 202020750750.1, application No. 2020.05.08, discloses a multipurpose lifebuoy for ships, which can provide stored water for personnel falling into water, besides helping the personnel falling into water to provide buoyancy, by arranging a first rubber plate, a second rubber plate and a rubber air bag, but the device has the disadvantages of large overall weight, inconvenience in storage and retraction, and incapability of accurately delivering the water to the vicinity of the personnel falling into water far away from the ship, so that it is of great significance to design a ship lifesaving device which can realize lifesaving on the personnel falling into water and has high efficiency and is not subject to abrasion.
