ship anti-capsulation device

Abstract

The invention discloses a novel anti-capsizing device for ships, -relates to the technical field of ships, includes the hull and bottom unit; A bottom device is arranged at the bottom of the hull, thebottom device comprises a rectangular steel frame, central keel, - telescopic device, A central keel is arranged at the central position inside the rectangular steel frame, two expansion and contraction devices are arranged inside the rectangular steel frame, the telescopic device comprises a retracting and releasing mechanism, telescopic mechanism, balanced floating plate, gear transmission mechanism, driving mechanism, high power intelligent motor and frame, A telescopic device is telescopically spread and attached to that water surface by a balanced floating plate, to maintain a stable condition of the ship at low speeds or moorings, The invention improves the safety and stability of the ship when sailing at sea, locks the telescopic device at high speed through the driving mechanism,avoids the influence of external environment on the telescopic device, and opens the telescopic device at low speed or mooring state, so as to facilitate the adjustment of the telescopic device to keep the ship stable.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship anti-overturning device. Background technique [0002] Ships will inevitably produce various swaying in wind and waves, among which rolling is the most significant and has the greatest impact. When the ship is moored or at low speed, when the swell period is close to the ship's natural rolling period, the ship's swing is more severe than when it is sailing. However, only when the speed of the ship is high, conventional fin stabilizers can effectively stabilize the roll; when the ship is at low or zero speed, since the velocity of the water flowing over the surface of the fin is zero, the lift of the fin will also disappear, so this At this time, the stabilizer fins can hardly perform stabilization. For ships that still need to be stabilized at low speeds or moored, traditional fin stabilizers are no longer applicable. Strong swings can easily cause ships to roll over, caps...

Problems solved by technology

However, only when the speed of the ship is high, conventional fin stabilizers can effectively stabilize the roll; when the ship is at low or zero speed, since the velocity of the water flowing over the surface of the fin is zero, the lift of the fin will also disappear, so this fins can hardly stabilize

For ships that still need to be stabilized at low speeds or moored, traditional fin stabilizers are no longer applicable. Strong swings can easily cause ships to roll over, capsize, and cause shipwreck
