Description

Dual-hull ship

The invention belongs to marine ship.

Present boats and ships mostly belong to the floating boats and ships, waved by the influence of wave and do not stop, and are unsuitable for work chronically life or go to open up to off-lying sea of people at sea.

When the ocean did not have wave fully, the sea was the plane, and this moment, each position of boats and ships was subjected to a static parallel component group that makes progress, and can claim the DC component that boats and ships are stressed.When wave, boats and ships have been subjected to an AC compounent power again, and it is time dependent function.Fig. 1 is the reason scheme drawing of Ship Swaying.When unrestrained peak arrived stern, more seawater flooded and causes AC compounent power F, will lift on the stern, and ship rotates with rotative speed ω to anticlockwise direction; When wave entered hull fully, as shown in Figure 2, ship rotated with rotative speed-ω again along clockwise direction.When fore is in unrestrained paddy, as Fig. 3, fore born-effect of F power, falls under the fore, and ship rotates with rotative speed ω toward anticlockwise direction again, and wave does not stop, and waves incessantly, and billow hits, and seel gets more severe.

Existing antirolling apparatus has three kinds.First kind subtracts and shakes device for dress aboard ship, sees Fig. 4.Subtract and shake device by vibration measuring system with subtract swing mechanism and form, oscillation pickup is measured amplitude, phase place and the frequency of ship vibration.Subtract that to shake device be that band is eccentric producing the mechanism of centnifugal force, produce an opposite excitation by it and subtract and shake.Obviously, this device balance and stabilizing efficiency are poor.Second kind is to adopt catamaran to increase beam, sees Fig. 5, Fig. 6.Though the pivot angle θ of ship reduces to some extent with the increase of the width of hull, can not eliminate the influence of wave to hull.The third is an oil platform, sees Fig. 7.It is built to hull in the air and goes, and has eliminated the influence of wave to hull, and the truss that is deep into the seabed supports.Though this device can be eliminated and wave, and can not be used for the deep-sea, can not navigate by water.

Purpose of the present invention is worked on the ocean for a long time, is lived for a kind of being fit to is provided, and can eliminate wave fully to waving that hull causes, and keeps the boats and ships stationarity and guarantee safety, the dual-hull ship that can navigate by water on the ocean.

Technical scheme of the present invention is the DC component power that keeps the suffered seawater of hull, eliminates the effect of wave to the AC compounent power of hull; Specific design is: the maxim according to wave wave peak is separated into upper and lower hull to hull; By truss upper and lower hull is linked into an integrated entity, and have passage to be communicated with upper and lower hull; Upper hull is positioned on the wave, assign a work on it district and living quarters; Lower hull is arranged in the water part of the truss under the wave; Fix the position of each buoyancy tank by truss; The elastic body of stretching or contracting is housed between each buoyancy tank and the truss.Truss bears and transmits various power for the backbone of whole ship; The keel that are connected as a single entity in length and breadth are equipped with in the truss bottom, around the part and on the keel claw are housed in the water of truss; Ship-borne equipment also is housed on the ship, comprises computing machine depth of water self-checking device, computer level self-checking device; And control setup or power plant; When design, should make the centre of buoyancy of whole ship be higher than the center of gravity of putting in order ship, to guarantee stability; When control system guarantees that wave fluctuates between upper and lower hull, though wave constantly fluctuates, upper hull only is subjected to static buoyancy, and has eliminated the effect of the AC compounent power that wave causes; The present invention is particularly suitable for doing safety, super steady ocean research, and exploitation, production, construction home base also can be done super steady pleasure-boat or super steady warship or super steady floating terminal or deepwater opportunity airfield or mobile operational base.

Technique effect of the present invention is to have eliminated the influence of wave to hull, has significantly alleviated and has waved; Also have horizontality, stability, safety and alerting ability etc. in addition.Level adjustment system is by level indicator, and computing machine and actuating unit are formed, and the water yield that it can constantly be regulated in each buoyancy tank is come level-off.Stability shows that the centre of buoyancy is higher than center of gravity, can reduce automatically after the heel, and in addition, upper hull itself can prevent that also ship from continuing to tilt, and as being 200m as the captain, the spatial altitude of upper hull and buoyancy tank is 10m, then works as heel, for $\mathrm{tg\θ}=\frac{5m}{200m}=0.025$ , leaning angle is 1.4 °, seawater can flood the upper hull base angle, produces a power by it, has just settled out the also inclination of imperceptible ship of people in the upper hull.Safety shows that buoyancy tank is many independently casees, even there is the minority buoyancy tank to intake for some reason, but measurements and calculations machine system each hatch door of SELF CL is eliminated the shipwreck accident; Next is around the truss bottom reaches claw to be housed, if hit a submerged reef or bumper boat, and the truss distortion, buoyancy tank can not damage; The buoyancy tank rubber pad is passed to truss with buoyancy, and the middle part is connected on the truss by a king bolt on the buoyancy tank, and therefore, when bigger distortion appearred in truss, buoyancy tank can not be out of shape yet and leaks; In addition, if upper hull is attacked when damaging, ship is made submarine usefulness here, and full complement and important item can be transferred in the lower hull through the passage that communicates up and down and go; When lower hull was broken sinking fully, upper hull separated automatically with lower hull, and upper hull is divided into each canoe more automatically, and the personnel and the important item of lower hull can be transferred to upper hull; So have the maltilevel security support system.Alerting ability shows can be with the power plant of towboat or oneself dress, and the place of wanting of what is the need for is taken office in the navigation of this ship.Economy shows that this hull only is subjected to the static(al) of vertical direction, power by bending not, and therefore, the hull cost is lower.
