Life-saving device and diving device

Abstract

Disclosed are a life-saving device and a diving device. The life-saving device comprises a housing and a Beidou communication terminal. The housing has a first outer surface, which faces toward a Beidou satellite when a user uses the life-saving device. The Beidou communication terminal is disposed in the housing and connected in a sealing manner with the housing, and is used for communication with the Beidou satellite and transmitting location information to the outside. The Beidou communication terminal is connected with one end, in the length direction, of the first outer surface, and is arranged at an angle of 35-55 degrees with an extending direction of the one end, in the length direction, of the first outer surface. According to the invention, when the life-saving device is in use, the Beidou communication terminal faces almost perpendicular to the Beidou satellite, with a radio frequency gain attenuation degree of 0.1dB, and the radio frequency signal transmitting ability of the Beidou communication terminal is improved.

Description

technical field [0001] The invention relates to a lifesaving equipment and diving equipment. Background technique [0002] At present, wild living environments such as deserts, jungles, and oceans are very harsh, and various disasters will come unexpectedly. For wilderness survivors or workers, it is very important to keep abreast of the predicament they are facing, inform others, and seek rescue. When calling for help in distress, contact others through various means. [0003] The traditional ways of calling for help include fireworks signals, body signals, semaphore signals, sound signals, and reflective light signals. These help ways are often limited by the actual situation, and the signals sent are difficult to be found by other people or search and rescue personnel. [0004] In particular, when deep-water workers are in distress on the water, and their lives are threatened and the rescue ship cannot arrive at the scene immediately, they can put inflatable floating ba...

AI Technical Summary

Problems solved by technology

[0005] However, due to ocean currents, wind and waves, etc., the inflated buoyancy bag of the life-saving equipment of deep-water workers is likely to drift away from the distressed location, and the deep-water workers cannot be rescued in time even though they successfully escaped.
