Embodiment Construction

[0026] A concealed marine airbag system of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 1 to Figure 7 As shown, in the present embodiment, the present invention provides a kind of marine safety airbag system, is characterized in that: it comprises rail barrel 3, high-strength spring 6, ejection bar 2, annular electromagnet 5, safety airbag equipment, control system .

[0028] In this example, the guide rail cylinder 3 is provided with a base 7, a cylinder body, a supporting leg 9, a horseshoe foot 8, a hollow screw 10, and a nut 14; the guide rail cylinder base 7 is fixed on the back of the deck, and the cylinder Body and base 7 are fixed, and there are two circular holes on the upper end of the cylinder body, and the distance between the holes and the upper end on the cylinder body just equals the length sum of the length of the ejection bar 2 ejection parts and the length of the high-strength...

Abstract

The invention provides a marine safety airbag system. The marine safety airbag system comprises a guide rail cylinder, a high-strength spring, an ejection rod, an annular electromagnet, safety airbagequipment and a control system. When the ship body tilts to a large extent due to emergencies such as contact reef water leakage, storm influence and the like, the electromagnet is powered off, and the ejection rod instantly ejects to the upper side of the water surface under the action of restoring force of the high-strength spring. At the same time, a sodium azide layer in the safety airbag assembly arranged in the ejection rod is immediately subjected to gas explosion, nitrogen generated by chemical reaction is immediately inflated to the folding airbag after passing through the filter layer, and the airbag is instantaneously inflated and floats on the water surface. When the ejection rod is ejected out, the spring metal bar connector which is originally compressed is ejected out, and the ejection rod is prevented from moving towards the direction of the high-strength spring. The safety airbag system for the ship can stabilize the ship body in time, increase the buoyancy of the shipbody, reduce the sinking speed and even prevent the ship body from sinking, and is very worthy of application and popularization in actual life.

Description

technical field [0001] The invention relates to the field of ship lifesaving equipment, and specifically designs a ship safety airbag system. Background technique [0002] When a ship sails on the water, it often encounters many uncontrollable situations such as wind and waves, hitting rocks, etc. If you are not careful, it will cause the tragedy of ship destruction and death. Among them, ship capsizing is a relatively common cause of major accidents, such as On June 1, 2015, the luxury cruise ship "Oriental Star" sailing from Nanjing to Chongqing capsized in the Damazhou section of the Yangtze River in Jianli, Hubei, killing more than 400 people. [0003] In a ship sinking accident, every second the ship sinking time is slowed down, one more second of precious time can be bought for the rescue. If the sinking of the hull can be prevented, it is possible to greatly recover the heavy losses caused by the shipwreck. However, in several shipwreck accidents in recent years, fo...
