Emergency radio position mark indicating device with function of indicating position of shipwreck in real time

Abstract

The invention relates to an emergency radio position mark indicating device with a function of indicating the position of a shipwreck in real time. The device comprises an emergency radio position indicating mark, an air bag connected with the emergency radio position indicating mark through a connecting member, a high-pressure gas storage device connected to an air bag inlet, a position indicating lamp assembly mounted on the top of the air bag, a cord connected to the hull and fastened on the bottom end of the air bag and a box for placing the above-mentioned components, and the box is connected to a hydrostatic pressure release device through a frangible rope. The device has the advantages that after a ship is sunk, the emergency radio position indicating mark and the air bag are connected to the shipwreck hull by the cord, the displacement keeps basically synchronized, and the position of the shipwreck is accurately indicated by the emergency radio position indicating mark, the airbag and the position indicating lamp.

Description

technical field [0001] The invention belongs to the technical field of ship distress alarm, positioning, safe search and rescue, helping to guide ships to navigate and marking the position of sunken ships and sunken objects (underwater obstacles), and relates to a sunken ship position indicating device, in particular to a sunken ship that can mark a sunken ship Emergency radio position indicating beacon device at the actual location. Background technique [0002] Due to the complexity and unpredictability of the sea environment, shipwreck accidents occur frequently. Usually, after the sinking of the ship, the emergency radio position indicator will automatically pop up and float to the surface of the water, and send out a distress signal. The distress signal will be forwarded to The ground station reports the position of the radio position indicating beacon of the current sunken ship, platform information, etc. [0003] The traditional emergency radio position-indicating b...

AI Technical Summary

Problems solved by technology

[0004] One is that the emergency radio position-indicating marker is in a state of self-floating with wind, waves, currents, etc. on the water surface. It may be affected by strong winds and waves, and stay away from the sunken ship. At the same time, the position of the sunken ship may change due to wind, waves, and currents. The position information of the sunken ship provided has a large deviation, which misleads the search and rescue operations and is not conducive to the rapid and accurate implementation of rescue

[0005] Second, the emergency radio position indicating sign is small in size, the target is not eye-catching, and it floats on the water surface, so it is difficult to search and rescue ships, planes, etc. to find emergency radio position indicating signs and shipwrecks

[0006] The third is that if the emergency radio position-indicating beacon cannot be activated automatically, it cannot send out a distress signal and cannot mark the location of the sunken ship.

[0007] Fourth, the battery capacity of the emergency radio position-indicating beacon is limited (usually 48 hours). If the battery is exhausted, it cannot continue to send out distress signals and cannot mark the location of the sunken ship.
