Function Description

(1) Breach sealing

The breach in the hull is plugged tightly by the air bag to realize the sealing operation. The airbag is usually in a contracted state, and it is inflated and inflated during work to block the breach of the hull. The shape of the airbag is a flat cylinder. During the sealing operation, the middle part of the airbag is placed at the breach of the hull, and the airbag is inflated by an electric air pump or a foot-operated air pump to make the airbag larger and generate pre-tightening force with the breach of the hull. After expansion, the shape and size of the breach can be followed to achieve sealing, and the airbag can be fixed on the breach of the hull by pre-tightening force. The airbag is made of a new type of high-strength TPU composite material through mold hot-press bonding, which can not only ensure sufficient pressure bearing capacity and wear resistance, withstand seawater pressure and prevent the airbag from being scratched by irregular holes, but also make the airbag It has good flexibility, which is convenient for folding and storage and quick unfolding and withdrawal. The specific operation method is as follows:

1) Deploy the airbag-type emergency blocking device, and two people cooperate to place the airbag body at the breach of the hull (about half of it protrudes outside the breach, and the side with the inflation and deflation valve faces the interior of the hull).

2) Connect one end of the connecting air pipe to the inflation end on the electric air pump (or pedal air pump) and tighten it, then open the cover of the air bag filling and deflation valve, and connect the other end of the air pipe to the inflation and deflation valve. Connect and screw tight.

3) Connect the threaded end of the operating handle with the connecting boss on the air bag body, one person holds the operating handle, places the air bag at a suitable position for the breach, and the other person starts the electric air pump or steps on the foot air pump to inflate Operation. After the airbag body is full, turn off the electric air pump or stop stepping on the pedal air pump, rotate and pull the joint connecting the air pipe from the inflation and deflation valve (the inflation and deflation valve has a self-locking sealing function), and cover the inflation and deflation valve Valve cover, to complete the expansion and sealing operation.

4) When withdrawing, one person connects one end of the connecting air pipe to the deflation end of the electric air pump (or pedal air pump) and tightens it, starts the electric air pump or steps on the foot pedal air pump to deflate, and one person assists the air bag body Deflate and fold according to the requirements. When there is no air in the airbag, fold it up. Then retract the electric air pump (or pedal air pump), connect the trachea and other equipment to complete the withdrawal operation.

(2) Anti-sinking and lifesaving

Anti-sinking in the cabin. Plug the airbag into the water-filled cabin or the empty cabin that needs to provide buoyancy, use the connecting air tube to quickly connect the airbag and the electric air pump (or foot air pump) through the quick connector, and start the electric air pump (or foot air pump) to the airbag Inflated, the air bag can provide anti-sinking buoyancy in the cabin after it is inflated and inflated. The same operation is adopted for other compartments, and the anti-sinking function is realized by providing sufficient buoyancy for the boat in the compartment so that it does not remain unsinkable.

Lifesaving at sea. Expand multiple airbags, use the connecting air tube to quickly connect multiple airbags and electric air pumps (or pedal air pumps) through quick connectors, and start the electric air pumps (or foot pedal air pumps) to inflate the airbags in sequence. After the airbag is inflated, connect a plurality of airbags into one body through the upper (or lower) lug of the airbag with one fastening belt, and then connect the airbags together through the lower (or upper) lug of the airbag with one fastening belt. Finally, the fastening belt is tightened, so that a plurality of airbags are arranged to form a floating platform, and the personnel on the ship that cannot realize the anti-sinking ability in case of danger can provide the lifesaving function at sea.

(3) Inflation and deflation control

The inflation and deflation control relies on the inflation and deflation valve, electric air pump (or pedal air pump) and connecting air pipe to implement.

1) Electric charging and deflation method

The charging cable that comes with the electric air pump has multiple connectors, which can be connected to a variety of power sources, not only to the output interface of the lithium battery, but also to the battery on board or the socket in the cabin. When inflating, first connect the two ends of the connecting air pipe to the inflating end of the electric air pump and the inlet and exhaust valves of the air bag body, and use the charging line of the electric air pump to connect the power supply, then turn on the switch of the electric air pump to adjust the pressure value , start the electric air pump to inflate; after the airbag body is fully inflated, turn off the electric air pump, rotate and pull out the connector connecting the air pipe from the inflation and deflation valve, cover the inflation and deflation valve cover, and unplug the charging cable connector to complete the inflation Operation. When deflated, operate in the same order as above, the difference is that the connecting air pipe needs to be connected to the deflated end of the electric air pump.

2) Pedal inflation and deflation

When inflating, first connect the two ends of the connecting air pipe to the inflation end of the foot-operated air pump and the inflation and deflation valve of the air bag body, and then step on the panel of the foot-operated air pump up and down with your feet to inflate the air bag body; the air bag body After inflating, rotate and pull out the joint connecting the air pipe from the inflation and deflation valve, and cover the inflation and deflation valve cover to complete the inflation operation. When deflation, also follow the above sequence, the difference is that the connecting air pipe needs to be connected with the deflation end of the pedal air pump. When necessary, manpower can also be used to squeeze the airbag body to assist deflation and increase the deflation speed.

working principle

The present invention mainly solves three technical problems: one is to realize the multiple functions of emergency sealing in the cabin of the large-scale breach of the hull, anti-sinking of the ship and rescue at sea; The blocking speed and effect are improved.

The working principle of the present invention is:

1. Adopt air bag blocking technology. Make full use of the advantages of the airbag, which can be large or small, can be adjusted into any shape, has good water sealing performance, and light weight, and uses the airbag as a sealing body to realize emergency sealing of large breaches. The airbag can adjust the external dimensions and the rigidity of the airbag body according to the amount of inflation, so as to adapt to the hull breaches of different sizes and shapes, and to completely seal the breaches as much as possible. The airbag material is made of high-strength TPU composite material with good scratch resistance, which ensures the dual requirements of high material strength and good flexibility.

2. Adopt quick connector technology. The filling and deflation valve, connecting air pipe, electric air pump and pedal air pump are all mature products in the market, which improves the standardization of the large breach air bag emergency sealing device in the hull. The joints of the air valve, the connecting air pipe, the electric air pump and the pedal air pump are matched with each other, and a fast and reliable air-tight connection can be realized, which improves the working efficiency and reliability of the whole set of devices.

3. Adopt multiple protection technologies. The designed airbag-type emergency sealing device can not only quickly seal large-scale breaches in the hull, but also provide anti-sinking capability for ships in distress, and provide life-saving floating platforms for people in distress, realizing multiple guarantee functions. The airbag body can be inflated and deflated by an electric air pump, and can also be inflated and deflated by a foot-operated air pump, which ensures the reliability of the airbag body inflating work. The electric air pump has a variety of connectors, which can be powered not only by the built-in lithium battery, but also by the battery on board or the socket in the cabin, which further ensures the reliability and rapidity of the inflation work of the sealing body of the bladder.
