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

Embodiment 1

[0026] Such as figure 1 , figure 2 As shown, the present embodiment is a reflective lens structure lifebuoy, including a lifebuoy body 11; said lifebuoy body 11 is provided with several segments of lenses 12, and each segment of lens 12 is a curved cylindrical structure, and these lenses 12 are based on the lifebuoy The center of the body 11 is distributed in a circular array at the center, so that these lenses 12 form a ring; the cross-section in the radial direction of each segment of the lens 12 is a layered structure, and the radial cross-section of the lens 12 is also a lens 12, and the cross-section of the radial direction of the lens 12 is that the dielectric constant changes continuously from 2 to 1 from the center to the outer layer; A reflective sheet-covered area and a non-reflective sheet-covered area 14 are formed on the peripheral surface, the surface of the reflective sheet 13 that is attached to the peripheral surface of the lens 12 is a reflective surface, a...

Embodiment 2

[0032] Such as image 3 , Figure 4 , Figure 5 As shown, the present embodiment is also a lifebuoy with reflective lens structure, including a lifebuoy body 21; The cross-section in the direction is from the center to the outer layer, and the dielectric constant changes continuously from 2 to 1; on the surface of the life buoy body 21, a reflective sheet 22 is laid to form a reflective sheet coverage area and a non-reflective sheet on the surface of the life buoy body 21 The reflective sheet covers the area 23, and the surface of the reflective sheet 22 that is attached to the surface of the lifebuoy body 21 is a reflective surface, and the reflective sheet is a thin metal sheet. When in use, if the person who falls into the water carries the lifebuoy with this reflective lens structure to escape, in the subsequent search and rescue operation, the radar wave sent by the radar transmitter of the search and rescue personnel will enter the lifebuoy body 21 from the non-reflect...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of lifesaving equipment, in particular to a reflective lens structure lifebuoy. Background technique [0002] Lifejackets, lifebuoys and lifeboats are commonly used marine lifesaving devices. Lifejackets, lifebuoys and lifeboats all use buoyancy to float on the sea, so that people can float on the sea and wait for rescue when they fall into the water. In order to make it easier for patrol personnel to find people in distress, some current life-saving devices are also equipped with signal transmitters, so that patrol personnel can find people in distress through signal receiving equipment. The life-saving device is also equipped with a power supply. Such a life-saving device has a complicated structure and needs to be charged when it is not used for a long time, and it is also easy to have a power failure during use, which is extremely inconvenient to use. [0003] In addition, there are also some life-savin...
