The function of the emergency buoy requires that the device is structurally strong, simple, reliable and can be operated by any person, and the driving mode of the buoy is independent of the electric power source possibly damaged inside the underwater equipment.
Emergency life buoys are typically locked to underwater equipment and when rescue needs to be sought, the buoy needs to be released to the surface. The existing buoy body release structure mainly comprises three forms, namely a mechanical chain lock structure, an air pressure release structure and a blasting release structure. The mechanical chain structure principle is that 4-6 rotatable lock bolts are arranged around a buoy body, the lock bolts are connected by adopting connecting rods in pairs, a rotating shaft of one lock bolt penetrates through a submarine pressure-resistant water tank, all lock bolts can be driven to rotate by the same angle to unlock from the operation rotation in the submarine, and the buoy body rises to the water surface by means of buoyancy, and the working principle is shown in figures 1 and 2.
The principle of the air pressure release structure is that a buoy body is manufactured and stored in a cylinder barrel, a sealing structure is formed on the inner wall of the cylinder barrel, the bottom of the cylinder barrel is connected with a high-pressure air driving device, a release signal cable of the device is connected into a boat through a cabin penetrating piece, release signals can be manually or automatically input from the boat to control high-pressure air to enter the bottom of the cylinder barrel so as to blow out the buoy body to leave the cylinder barrel, and then the buoy body floats to the water surface under the action of the buoyancy, so that the operating principle is shown in figure 3.
The principle of the explosion release structure is that the buoy body is fixed outside the pressure-resistant shell through an explosion release device, a control signal of the explosion release device is from a manual or automatic control terminal inside the pressure-resistant shell, the explosion release device is in a release state after explosion, and the buoy floats to the water surface under the action of buoyancy, and the working principle is shown in figure 4.
The buoy release method has the following defects: (1) By adopting a mechanical chain structure, the buoy body can leave the storage fence and float upwards only through buoyancy, the requirement on the release angle is high, a small amount of corrosion and clamping stagnation can cause the buoy to be incapable of being released, and meanwhile, the mechanical chain structure is complex, and the buoy body is not easy to rust and clamping stagnation for a long time; (2) The cylinder barrel is a pressure-resistant structure, and can be slightly deformed under the influence of seawater pressure, so that dynamic sealing friction between the buoy body and the inside of the cylinder body is increased or even blocked, and meanwhile, partial driving pressure is counteracted due to the fact that the pressure acts on the top end of the buoy body, so that the effective release depth of the structure is limited; (3) The buoy body can leave the storage fence and float upwards only through buoyancy, the requirement on the release angle is high, a small amount of corrosion and clamping stagnation can cause the buoy to be incapable of being released, in addition, the release driving mechanism is arranged outside the pressure-resistant shell, and when the electric control function fails, the operation cannot be performed manually.
