A spare buoyancy device for a ship belongs to the technical field of integral self-rescue safety of ships and is a safety technology for preventing the ship from overturning and sinking. The principle structure of the ship standby buoyancy device comprises a buoyancy air bag cabin, a buoyancy air bag with a pressure-limiting deflation valve, a shell plate, a fixing net, a high-pressure cold air bottle, a high-pressure cold air electromagnetic valve, a high-pressure cold air guide pipe, a pendulum bob water damping electric switch, a floater electric switch, a power source, a power source switch and a circuit wire. Before the ship sails, the power switch and the high-pressure cold air bottle switch are turned on, and the standby buoyancy device enters a standby state. When the ship body seriously inclines and overturns, the pendulum bob water damping switch is switched on, or the floater electric switch is switched on before the ship body sinks, the high-pressure cold air electromagnetic valve is opened, high-pressure cold air rapidly inflates the buoyancy air bag, pushes away the shell plate and pulls open the fixing net, and the buoyancy air bag is filled with air to generate enough buoyancy in water and transmits the buoyancy to the ship body through the shell plate and the fixing net. When the pressure intensity in the buoyancy air bag is too large, the pressure limiting deflation valve is opened for deflation, the air bag is prevented from being broken, and after the pressure intensity is reduced, the pressure limiting deflation valve is automatically closed to stop deflation.
船只备用浮力器属于船只整体自救安全技术领域,是防止船只发生倾覆和沉没的安全技术。船只备用浮力器的原理结构组成设备有:浮力气囊舱,带限压放气活门的浮力气囊,贝板和固定网,高压冷气瓶,高压冷气电磁阀,高压冷气导管,摆锤水阻尼电开关,浮子电开关,电源和电源开关,电路导线。船只航行作业前打开电源开关和高压冷气瓶开关,备用浮力器进入备用状态。当船体严重倾斜,倾覆前摆锤水阻尼开关接通,或船体进入沉没前浮子电开关接通,高压冷气电磁阀阀门打开,高压冷气快速给浮力气囊充气,推开贝板,拉开固定网,浮力气囊充满气在水中产生足够浮力,经贝板和固定网传给船体,扶正倾斜的船体和阻止船体下沉,防止船只发生倾覆和沉没事故,当浮力气囊内压强过大时限压放气活门打开放气,防止气囊破裂,压强降低后自动关闭停止放气。
