Shipborne temporary emergency shipwreck position indicating device

Abstract

The invention discloses a shipborne temporary emergency shipwreck position indicating device which comprises a suspension shell and a rotating shaft, a steel cable is wound on the rotating shaft, a permanent magnet is connected to the steel cable, a first transmission shaft is connected to the bottom of the suspension shell, and a second bevel gear and a third bevel gear are connected to the first transmission shaft. The suspension shell is connected with a second transmission shaft. An energy storage device is arranged between the second transmission shaft and the suspension shell. According to theshipborne temporary emergency shipwreck position indicating device, through arranging the steel cable with the changeable length and a permanent magnet connected with the steel cable at the bottom of the suspension shell, when the ship body turns over, the suspension shell suspends on the water surface as a warning buoy, the permanent magnet can be attracted to the ship body, the steel rope is continuously pulled, when the overturning position is not deep, the overturning position can be accurately identified, when the overturning position is too deep, due to the combined action of magnetic attraction and buoyancy, the permanent magnet is separated from the ship body and starts to be automatically retracted, and automatic adjustment can be achieved according to different conditions.

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
