Abstract
The present invention relates to a tilt-prevention slow sinking system for ships, which comprises a signal generation system, a control system, gas bag systems and locking mechanisms, wherein the gas bag systems are arranged on side wale plates on both sides of the hull, and each gas bag system is composed of a gas bag casing and a gas bag in which pressure gases are arranged; the gas bag casing is locked by the locking mechanism; the start of each locking mechanism is controlled by the control system, and the control system is controlled by the signal generation system. When a ship tends to tilt, the signal system sends out signals to control the locking mechanisms to start through the control system, and then, the gas bag casings are unlocked under the action of the pressure gasses in the gas bags; the gas bags expand fast without the constraint of the gas bag casings and respectively rapidly form the two large gas bags on both of the two sides of the hull, and the large gas bags generate buoyant forces to fully counteract the tilt torque of the hull, so that the hull is vertical to prevent the ship from tilting. When the ship sinks, the large gas bags can reduces the sinking speed of the ship so as to provide more time for passengers to escape.
Description
Technical field
The present invention relates to boats and ships, the system that particularly is used on the boats and ships prevent Ship's Capsize He slows down the boats and ships rate of sinking.
Background technology
At present, boats and ships are met high wind or situation such as are hit a submerged reef and when toppling prominent, can cause very big personal casualty, its major cause is: the whole process time of Ship's Capsize is of short duration, as shown in Figure 9, when boats and ships toppled meeting with billow, the whole process of toppling had only 6 short seconds, and the passenger does not have time enough to grasp life jacket or buoy quoit is escaped from passage.
China's " boats and ships " magazine the 2nd phase of April in 2003 (63-64 page or leaf) article " is introduced a kind of advantages of simplicity and high efficiency boats and ships and is prevented shaking design ", discloses a kind of boats and ships anti-sway system, and this system is provided with the air bag of extending/drawing back type at the bilateral of boats and ships; The principle of work of this system is: when rolling has just taken place in stormy waves hull, the generation bank moment is initial, the gas injection machine is rapidly to the airbag aeration of the outboard both sides of ship midship, make it to produce the bank moment that the floating righting moment of lifting power can fully be offset hull, keep setting upright of hull, to alleviate the at random rolling of stormy waves to hull.
The defective of this system is: 1, because the process time of Ship's Capsize is short, prevent the effective time shorter (greatly in 0.6 second) of Ship's Capsize, when boats and ships generation emergency situation, just the air bag to the outboard both sides puts on the air, air bag can not fully launch, therefore, this system is difficult to play the effect that prevents Ship's Capsize and slow down the boats and ships rate of sinking; 2, will improve aeration speed, this system must adopt high-performance gas injection machine, the cost height, and complex structure, bulky.
Summary of the invention
Technical matters to be solved by this invention is: a kind of slow sinking system of boats and ships anti-dumping that can prevent Ship's Capsize and slow down the boats and ships rate of sinking is provided.
