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

[0024] Such as figure 1 , figure 2 As shown, a kind of buoy buoy of the present embodiment comprises a buoy buoy body 11, and several radar reflectors are arranged in the buoy buoy body 11, and several radar reflectors are distributed in an annular array centered on the center of the buoy buoy body 11, and each radar The reflectors all include a Lunberg lens 12 and a reflector 13, the Lunberg lens 12 is made of a foam medium material, the reflector 13 is a thin metal sheet, and a reflective surface is formed on the reflector 13, the reflection of each radar reflector The reflective surface of the element 13 is attached to the surface of the Lunberg lens 12. The foamed dielectric material used to make the Lumber lens 12 is an existing material. The foamed dielectric material is just like the technology described in the patent No. 201910867980.8 titled "Dielectric Material and Dielectric Material Production Method" applied by the applicant. The scheme is the same, so it will ...

Embodiment 2

[0032] The difference between this embodiment and embodiment 1 is: as image 3 As shown, the diameter of the Luneberg lens 22 of each radar reflector 21 is larger than the cross-sectional diameter of the lifebuoy body, so that these radar reflectors 21 divide the lifebuoy body into several floating sections 23 . In the production process of this embodiment, the radar reflector 21 is integrally connected together when foaming to form the body of the life buoy. This design forms a recess between two adjacent radar reflectors 21. During use The underarm position of the person who fell into the water can clamp the concave position, which makes the life buoy more convenient to use.

Embodiment 3

[0034] The difference between this embodiment and Embodiment 1 lies in that: the reflection direction of the partial directional radar reflector and the reflection direction of the partial omnidirectional radar reflector are different. Specific as Figure 4 , Figure 5 As shown, there are two directional radar reflectors in Group A 31, which are respectively the first radar reflector 311 and the second radar reflector 312; there are also two directional radar reflectors in Group B 32, which are the first radar reflector 312 respectively; Three radar reflectors 321 and the fourth radar reflector 322; the first radar reflector 311, the second radar reflector 312, the third radar reflector 321 and the fourth radar reflector 322 are arranged in turn around the center of the buoy buoy body 33, Wherein: the central reflection direction L1 of the first radar reflector 311 and the central reflection direction L1 of the third radar reflector 321 are both perpendicular to the reference...

Abstract

The invention relates to a life buoy which comprises a life buoy body and is characterized in that a plurality of radar reflectors are arranged in the life buoy body, the radar reflectors are distributed in an annular array mode with the center of the life buoy body as the center, each radar reflector comprises a luneberg lens and a reflecting piece, the luneberg lenses are made of a foaming medium material, a reflecting surface is formed on the reflecting piece, and the reflecting surface of the reflecting piece of each radar reflector is attached to the surface of the luneberg lens. The lifebuoy has the advantages of being simple in structure, scientific in design, convenient to use, capable of displaying large images on the radar screen and avoiding omission of search and rescue, goodin 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 lifebuoy ring. 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-saving devices that are eq...
