The invention relates to the field of ships, in particular to a cylinder
gas release collision buffer safe ship. A chute is sleeved at the upper end of a buffer sliding block and is longer than the upper end of the buffer sliding block; the rear surface of the buffer sliding block is tightly attached to the front end of a sliding rod; the front section of the sliding rod is arranged outside a cylinder
barrel, and the rear section of the sliding rod is inserted into the cylinder
barrel; a
piston is arranged at the rear end of the sliding rod and can seal gas in a cylinder; a spring is arranged behind the
piston; the rear end of the cylinder
barrel is provided with a gas hole; if the ship runs against a rock, the buffer sliding block is impacted first, the buffer sliding block, the sliding rod and the
piston move rearwards simultaneously, the spring is compressed, the gas in the cylinder is discharged from the gas hole, the buffer sliding block is subjected to
high resistance when moving rearwards because the gas hole is small, the ship speed is reduced, time for the ship to run against the rock is greatly prolonged, and
impact force applied to the ship is greatly reduced to protect a ship body according to the theorem of impulse; and if a ship without the buffer device runs against the rock, the
impact force applied to the ship is high, the ship body can be broken, water can enter a ship bottom bin and the ship can be sunken.
