The invention relates to a life buoy with a reflecting lens structure. The life buoy comprises a life buoy body; a plurality of sections of lenses are arranged in the life buoy body, each section of lens is of a bent cylinder structure, and the lenses are distributed in a circular array by taking the center of the life buoy body as the center, so that the lenses are encircled into a circular ring;the cross section of each section of lens in the radial direction is of a layered structure, and the dielectric constant of the cross section of each section of lens in the radial direction continuously changes from 2 to 1 from the center to the outer layer; a reflector plate is laid on the circumferential surface of each section of the lens, so that a reflector plate covering area and a non-reflector plate covering area are formed on the circumferential surface of the lens, and the surface, attached to the circumferential surface of the lens, of the reflector plate is a reflecting surface. The life buoy has the advantages of being simple in structure, scientific in design, convenient to use, capable of displaying large images on a radar screen and avoiding omission of search and rescue,good in safety, convenient to use and the like.
本发明涉及一种反射透镜结构救生圈,包括救生圈本体;所述救生圈本体中设有若干段透镜,各段透镜是弯曲状的柱体结构,这些透镜是以救生圈本体的中心为中心呈圆形阵列分布的,以使这些透镜围合成圆环;各段透镜径向方向的横截面是分层结构,且透镜径向方向的横截面从中心至外层是介电常数从2到1连续变化的;各段透镜的周向面上铺设有反射片,以在透镜的周向面上形成反射片覆盖区域和非反射片覆盖区域,反射片上与透镜的周向面贴合的面是反射面。本发明具有结构简单、设计科学、使用方便、可实现在雷达屏幕上呈现出大的影像,避免出现搜救的遗漏、安全性佳且使用方便等特点。
