Rescue underwater vehicle / 2334650

FIELD: transport.

SUBSTANCE: invention relates to life-saving methods in emergent evacuation from sunk ship. Proposed method consists in that prior to filling rescue means with compressed air the ship crewman should latch his halyard safety hook on ship guard rails. Said rescue means filled with compressed air pushes said crewman to water surface. Note here that said halyard is passed through roller brake device fitted at crewman rescue means and connected via gearset with brake device head roller rpm regulator to allow control over halyard forward speed. This prevents fast surfacing, hence, origination of caisson disease.

EFFECT: safe evacuation.

The invention relates to rescue citizens in emergency situations and can be used for emergency evacuation from the sunken boats.

Known the Way of salvation citizens during emergencies and device for its realization", patent No. 2373979, consisting in the fact that equip the craft group means - places for evacuation of citizens with tanks of compressed air, a compressor to pump them in compressed air; provide each passenger and crew member's individual means - cocoons-overalls.

The disadvantage of this method is the possibility of occurrence of lacunar disease when unregulated rapid ascent rescue fleeing from a citizen on the surface of a pond.

Technical rezultata of the present invention is to prevent the possibility of decompression sickness among citizens fleeing from the sunken boats due to a controlled rate of ascent.

This is achieved by the fact that prior to filling with compressed air rescue citizen sunken boats gears carbine file for the rails aboard the vessel; after completing rescue compressed air pushes it to the surface of the reservoir, while motormouse stretch halyard through the roller tormoznoy the device, attached to the means of salvation citizen, and connected through a gearbox to control the rotational speed of the downstream roller brake device is arranged to control the translational speed of the file and prevents rapid ascent, and therefore, the occurrence of decompression sickness citizens fleeing from the sunken boats.

The essence of the method is that prior to filling with compressed air rescue citizen sunken boats gears carbine file for the rails aboard the vessel; after completing rescue compressed air pushes it to the surface of the reservoir, while motormouse stretch halyard through the roller brake device attached to the means of salvation citizen, and connected through a gearbox to control the rotational speed of the downstream roller brake device is arranged to control the translational speed of the file and prevents rapid ascent, and therefore, the occurrence of decompression sickness citizens fleeing from the sunken boats.

The way to protect against decompression sickness during the rescue citizens from sunken vessels, consisting in the fact that equip the craft group means - places for evacuation of citizens with containers for compressed who is an ear, compressors to pump them in the compressed air supply of each passenger and crew member's individual means - cocoons-overalls, wherein prior to filling with compressed air rescue citizen sunken boats gears carbine file for the rails aboard the boats, after completing rescue compressed air pushes it to the surface of the reservoir, while motormouse stretch halyard through the roller brake device attached to the means of salvation citizen and connected through a gearbox to control the rotational speed of the downstream roller brake device is arranged to control the translational speed of the file and prevents rapid ascent, and therefore, the occurrence of decompression disease in citizen fleeing from the sunken boats.
