Technical Field

[0001] The utility model relates to the technical field of ship anti-capsize airbags, in particular to a ship quick-change anti-capsize airbag. Background Art

[0002] Marine anti-capsize airbags are a type of ship safety technology. By installing airbags on the side of the hull, they provide additional buoyancy and stability in the event of an accident, preventing the hull from capsizing or sinking rapidly. These airbags, when inflated, provide buoyancy to the hull, ensuring it remains afloat and stable for a certain period of time, preventing it from sinking rapidly. During use, these anti-capsize airbags require a quick-change mechanism to replace the airbags, thereby improving their effectiveness.

[0003] However, most of the existing technical solutions have the following defects:

[0004] 1. When quickly replacing the anti-rollover airbag, the airbag box is quickly replaced through an insert and a slot. In actual use, the quick replacement through the insert and the slot does not have a good effect on limiting the position of the airbag box;

[0005] 2. Ordinary marine anti-capsize airbags have poor deployment effects, which affects the anti-capsize efficiency of the ship.

[0006] 3. The fixing and installation of the anti-overturning airbag structure is not convenient enough. Therefore, the present invention provides a quick-change anti-overturning airbag for ships to solve the above-mentioned problems. Utility Model Content

Rotate the fixing rod so that the fixing rod is threadedly connected to the middle part of the installation plate, thereby threading the fixing rod to the upper end of the hull. Loosen the limit block so that the first spring drives the limit block to slide inward at the upper end of the hull, thereby engaging the limit block with the outer side of the upper end of the fixing rod, thereby facilitating the fixed installation of the installation box.

[0021] 2. Pull the limit rod upward to make it slide upward in the middle of the fixed plate, so that the limit rod drives the second spring to extend, and then the limit rod separates in the middle of the connecting plate. Then pull the airbag box forward to make it slide inside the installation box, so that the airbag box drives the connecting plate to separate inside the fixed plate, which facilitates the quick replacement of the airbag box.

[0022] 3. By starting the gas generator, the gas generator inflates the airbag body, so that the airbag body pushes the connecting block to slide outward on the outside of the mounting block, and then the connecting block drives the third spring to compress, so that the connecting block is separated on the outside of the airbag body, so that the airbag body pushes the blocking plate to slide toward the front side, and then the blocking plate is separated on the inside of the shrapnel, ensuring a good deployment effect of the airbag.
