Embodiment Construction

[0024] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] As shown in Fig. 1 and Fig. 2, the present invention includes: tail side thruster 1, middle side thruster 2, bow side thruster 3, first sounder 4, middle sounder 5, tail sounder 6, power System 7 , main thruster 8 , vertical reference element 9 , heading sensor 10 , three-coordinate controller 11 and thrust distribution logic unit 12 .

[0026] The tail propeller 1, the middle propeller 2 and the bow propeller 3 are all ducted propellers, which are propeller pairs consisting of left and right parts. The tail propeller 1 is arranged on both sides below the stern. The middle thrusters 2 are arranged on both sides below the middle of the ship, and the bow thrusters 3 are arranged on both sides below the bow of the ship. Tail side propeller 1 , middle side propeller 2 and head side propeller 3 all comprise prime mover 14 , drive shaft...

Abstract

A medium-small ship water cushion anti-sinking system belongs to the technical field of ship ocean engineering. The present invention comprises a front thruster, a back thruster, a middle thruster, a front depth sounder, a back depth sounder, a middle depth sounder, a dynamic system, a principal thruster, a vertical fiducial element, a front direction sensor, a three-coordinate controller and a thrust distribution logic unit. The dynamic system is controlled by the thrust distribution logic unit and the three-coordinate controller to adjust and control the thruster at each side and operate under the rotate speed and torsion required by the control instruction. Each depth sounder senses the draft of the ship and sends a signal to the three-coordinate controller and the thrust distribution logic unit. The vertical fiducial element sends a signal of the deviation of the position of the ship and the vertical position. The front direction sensor sends the difference between the ship front direction and the required direction. The vertical fiducial element and the front direction sensor all send the signal to the three-coordinate controller and the thrust distribution logic unit, so as to adjust the action of each thruster in time and correct the secund sinking of the ship to be in accordance with the correct navigation direction. The present invention has obvious economic and social benefit.

Description

technical field [0001] The invention relates to an anti-sinking system for ships, in particular to a water pad anti-sinking system for small and medium-sized ships, and belongs to the technical field of marine engineering for ships. Background technique [0002] Ships, especially ocean-going ships, have been trying to avoid and cannot completely solve the accidents of water ingress and capsizing due to damage to the hull, resulting in huge economic losses and social impacts. In the existing technology, the invention patent of "ship anti-sinking injection system" with the application number of 200510111516.4 achieves the anti-sinking goal by completely occupying the damaged cabin of the ship with rigid foam plastics and preventing the intrusion of seawater. After a ship accident occurs, all personnel in the damaged cabin must be removed before anti-sinking operations can be carried out. If there is a slight delay, some personnel will be blocked in the cabin and fixed in place...
