The working principle is as follows: the helicopter in the technical scheme flies to the position near the position needing fire extinguishing, descends to a cylinder body hung on the helicopter and falls into seawater, and when the hanging rope has no traction force on the piston, the water outlet control valve is opened, the piston can slide downwards along the length direction of the cylinder body under the action of gravity, the one-way control valve can be opened, seawater can enter the cylinder body from the inlet of the cylinder body, air in the cylinder body can be discharged outside through the water outlet control valve, the cylinder body can descend in the seawater, when the seawater contacts the piston, the seawater can flow into the upper side of the piston from the one-way control valve and enter a water storage cavity enclosed by the cylinder body and the piston, when the residual air in the cylinder body just enables the cylinder body to float on the sea surface, the water outlet control valve can be automatically closed, the piston can stop when descending to be dragged by the hanging rope, the one-way control valve can be closed, the helicopter ascends to enable the piston and the cylinder, the helicopter lifts the cylinder above the position where the fire occurs, opens the water outlet control valve, and the cylinder moves downwards relative to the piston under the action of gravity, so that the seawater in the cylinder is sprayed out of the control valve and falls into the lower ignition point, thereby achieving the purpose of fire extinguishing; the barrel body filled with seawater is suspended below the helicopter by the suspension rope, and the helicopter can be positioned above the position where a fire happens only by changing the length of the suspension rope no matter the fire condition, so that the barrel body can discharge water at a short distance to extinguish the fire, and the offshore fire extinguishing efficiency is improved.

In the above marine fire extinguishing apparatus, the cylinder is arranged in a cylindrical shape, the collision switch for closing the water outlet control valve is arranged on the outer peripheral surface of the upper portion of the cylinder, a floating body capable of triggering the collision switch is sleeved on the cylinder, the floating body is arranged in an annular shape, and the floating body can float up and down along the length direction of the cylinder below the collision switch. The floating body is provided with the collision switch and triggers the collision switch, so that the barrel can float on the sea surface by utilizing the residual air in the barrel, and the consumption of fuel can be reduced when the barrel of the helicopter is filled with water and the barrel filled with seawater is lifted.

In the above fire extinguishing apparatus, the number of the collision switches is two, and the two collision switches are symmetrically distributed on the outer circumferential surface of the cylinder at intervals. The floating body is prevented from passing through the collision switch, so that the floating body does not play a role in triggering the collision switch.

In the above-mentioned marine fire extinguishing apparatus, an annular stopper seat for preventing the floating body from separating from the cylinder body is fixedly provided on the outer circumferential surface of the cylinder body, and the floating body is located between the collision switch and the annular stopper seat. The annular blocking seat can block the floating body falling along the length direction of the cylinder body, and the floating body is prevented from being separated from the cylinder body.

In the above-mentioned marine fire extinguishing apparatus, the water outlet control valves are distributed on the upper end surface of the cylinder in an annular array. The seawater in the cylinder flows out more uniformly, and the service life of the cylinder, the piston and the suspension rope is prolonged.

In the above fire extinguishing apparatus, the number of the one-way control valves is two, and the two one-way control valves are symmetrically arranged on the piston. The piston is prevented from being blocked when sliding downwards in the cylinder due to uneven stress.

In the above fire extinguishing apparatus, the lower end of the suspension rope is located in the cylinder, and the lower end of the suspension rope passes through the center of the piston and extends to a position close to the lower end of the cylinder. The cylinder body can hold more seawater when the device has better performance, and can extinguish fire as soon as possible.

Compared with the prior art, the barrel body is suspended below the helicopter through the suspension rope, so that the helicopter can be positioned above the fire occurrence position no matter the size of the fire on the sea, and the seawater in the barrel body can be sprayed to the fire occurrence position, thereby improving the fire extinguishing efficiency on the sea.
