A lifebuoy with breathing function and a lifesaving device with the lifebuoy

Abstract

The invention relates to a life buoy with a respiratory function and a lifesaving device with the life buoy. The life buoy mainly comprises a life buoy body, wherein air storage bags are arranged inside the life buoy body; the air storage bags are respectively connected with air inlet tubes, water outlet tubes and air outlet tubes; guide blocks are arranged inside the air storage bags; guide holes are formed in the guide blocks; sliding rods perpendicular to the axial direction of the life buoy body are positioned inside the guide holes; each end of each sliding rod is respectively fixedly connected with a buoyancy ball; the axes of the air inlet tubes, the sliding rods and the water outlet tubes are overlapped; the other ends of the air inlet tubes and the air outlet tubes are all exposed on the upper surface of the life buoy body; the other ends of the water outlet tubes are exposed on the lower surface of the life buoy body; under the action of external force of the buoyancy balls, the sliding rods move up and down together so as to change the communication states of the air inlet tubes or the water outlet tubes with the air storage bags. The water respirator, namely the life buoy provided by the invention, can flow on water for a long time, air can be provided for a person falling in the water, and thus accident of drowning can be prevented.

Description

technical field [0001] The invention relates to the technical field of rescue equipment, in particular to a lifebuoy with breathing function and a lifesaving device with the lifebuoy body. Background technique [0002] Among the common water transport vehicles at present, most of them are equipped with life-saving devices such as life buoys and life jackets to improve the survival rate of people who fall into the water when a disaster occurs. As common knowledge, the human body can theoretically survive for 3-7 days without the supply of food and water, depending on the state of physical fitness. However, when the crew and / or tourists fall into the water, most of them will drown within 8 hours even wearing life-saving gear. The main reason is that the human body can float on the water for a long time with the aid of life-saving devices. Under the action of wind and waves, the human body will float around and lose physical strength rapidly. After about 4-6 hours, the human b...

Problems solved by technology

The wind and waves will blow the river and / or sea water to the face of the human body, causing choking, and if the time is too long, even if the person wears the life-saving device and is in a floating state, drowning will occur
