A Shipborne Temporary Emergency Shipwreck Position Indicating Device

Abstract

The invention discloses a ship-borne temporary emergency shipwreck position indication device, which comprises a suspension shell and a rotating shaft, a steel cable is wound around the rotating shaft, a permanent magnet is connected to the steel cable, and the bottom of the suspension shell is A first transmission shaft is connected, the first transmission shaft is connected with a second bevel gear and a third bevel gear, the suspension housing is connected with a second transmission shaft, and the energy storage device is arranged between the second transmission shaft and the third bevel gear. Between the suspension shells, the temporary emergency shipwreck position indicating device is installed on the ship. By setting a steel cable that can be wound to change the length at the bottom of the suspension shell, and a permanent magnet connected with the steel cable, when the hull capsizes, the suspension shell is suspended On the water surface, as a warning buoy, the permanent magnet will be adsorbed on the hull and continuously pull the steel cable. When the overturned position is not deep, it can accurately mark the overturned position. When the overturned position is too deep, due to the combined effect of magnetic adsorption and buoyancy The permanent magnet breaks away from the hull and starts to retract automatically, which can be automatically adjusted according to different situations.

Description

technical field [0001] The invention relates to the technical field of ship-borne emergency equipment, in particular to a ship-borne temporary emergency shipwreck position indicating device. Background technique [0002] After the ship capsizes and sinks, according to the water traffic management requirements, emergency shipwreck position indicating signs must be set up for the sunken ship as soon as possible to mark the existence and location of the sunken ship to warn passing ships to prevent collision accidents. [0003] However, when the sunken ship is far away from the shore, the sea condition is bad or at night, and the visibility is poor, it is difficult to deploy the sunken ship's position indicating mark for the sunken ship in time. Due to the characteristics of wave drift, it is impossible to accurately identify the position of the sunken ship for a long time. [0004] Existing ship-borne temporary emergency shipwreck position indicating devices exist in the form ...

[0003] However, when the sunken ship is far away from the shore, the sea condition is bad or at night, and the visibility is poor, it is difficult to deploy the sunken ship's position indicating mark for the sunken ship in time. Due to the characteristics of wave drift, it is impossible to accurately identify the position of the sunken ship for a long time

[0004] Existing ship-borne temporary emergency shipwreck position indicating devices exist in the form of buoys, but because the buoys are floating on the water surface, there is a possibility of movement, and the position changes caused by floating will produce wrong guidance, causing passing ships to Avoiding the buoys and entering from the correct overturning position will cause a second overturning, and some buoys will be connected to the hull through ropes, but this method will also bring the buoys down when the overturning position is deep, so the buoys cannot Provide approximate overturned location, resulting in low collection efficiency
