a life buoy

Abstract

The present invention relates to a life buoy, comprising a life buoy body, characterized in that a number of radar reflectors are arranged in the life buoy body, and the several radar reflectors are distributed in a circular array centered on the center of the life buoy body, and each radar reflector includes A Luneberg lens and a reflector. The Luneburg lens is made of a foamed dielectric material. A reflective surface is formed on the reflector. The reflective surface of the reflector of each radar reflector is bonded to the surface of the Luneburg lens. The invention has the characteristics of simple structure, scientific design, convenient use, large image can be realized on the radar screen, avoiding the omission of search and rescue, high safety and convenient use.

Description

a life buoy technical field [0001] The present invention relates to the technical field of lifesaving equipment, particularly a lifebuoy. Background technique Lifejacket, lifebuoy and lifeboat are commonly used marine lifesaving devices, and lifejacket, lifebuoy and lifeboat are all using It floats on the sea due to the effect of buoyancy, so that people can float on the sea and wait for rescue in the case of falling into the water. For the convenience of patrolling When officers find people in distress, some life-saving devices are now equipped with signal transmitters, so that patrol personnel can pass the signal Receiving equipment to find people in distress, because the life-saving equipment is equipped with a signal transmitter, so that the life-saving equipment of this structure It is necessary to equip the power supply in the center. The structure of such a life-saving device is relatively complicated, and it needs to be carried out when it has not been used ...

AI Technical Summary

Problems solved by technology

The small radar corner reflector with this structure has the following disadvantages when it is applied to the life buoy: the first is that the reflection range of the small radar corner reflector is small, and it is easy to miss when searching; the second is that the small radar corner reflector is pointed Shaped structure, and the outer surface of the lifebuoy is easy to scratch the person who fell into the water, the safety is not good, and it is inconvenient to use
