The utility model relates to a kind of ship, especially a kind of ship that has buoyancy compartment.

Boats and ships are at the big maritime navigation of rivers, and the most dangerous is the shipwreck sinking, and this not only brings the loss of Cargo On Deck, even personnel also have injures and deaths.Causing the reason of shipwreck, be the broken water inlet sinking of ship of hitting a submerged reef mostly, or wind is anxious, and the wave is high, and ship is thrown.In the prior art, have in the outside of left and right two sides of a ship of ship and set up, but the still damping when ship and other reef bump against of its main function, can not prevent that broken sinking of ship or wind from throwing ship such as things such as tires.

The purpose of this utility model is to improve the deficiencies in the prior art, provide a kind of can high the wave is high at wind, hit into water, do not sink under the situations such as presence of fire, do not turn over, even overloading boat sinks because of serious, can not turn over yet, weight saving on ship, but the ship that floats of balance again are to guarantee the safety of personnel and goods in the water transportation.

The purpose of this utility model is achieved in that left and right two sides of a ship outside at ship, prolong to stern from fore, if one connects firmly and osed top side of a ship wing buoyancy compartment cavity with hull, be filled with the low density solid expanded material in the cavity, the density of expanded material is the 0.02-0.08 gram per centimeter ³As vinyon foam block or polystyrene plastics foam block, side of a ship wing buoyancy compartment is that the height of the 20-50% side of a ship wing buoyancy compartment of hull middle deck width is the 35-60% of hull middle deck width from the outwardly directed every edge lengths of left and right two sides of a ship of ship, the bottom surface of side of a ship wing buoyancy compartment is more than the specified loading water line of this ship, itself and horizontal surface press from both sides an angle and upwards stretch out, folded angle is 5-20 °, the volume of left and right side of a ship wing buoyancy compartment and be the 40-100% of the specified cargo-carring total displacement of volume of this ship; In the front deck of ship and rear deck, also be filled with described expanded material and constitute front deck buoyancy compartment and rear deck buoyancy compartment, forward and backward buoyancy compartment volume sum is the specified cargo-carring total displacement of volume 20-60% of this ship, the distribution of forward and backward buoyancy compartment volume should guarantee whole ship at full load balance, and run into stormy waves, also in a basic balance with the common power of lifting that produces of left and right side of a ship wing buoyancy compartment; In the middle deck of ship, constitute the middle deck buoyancy compartment between the base plate of ship and the cabin pedal, its volume is the 0-70% of the specified cargo-carring total displacement of volume of this ship, wherein also fills described solid foamed material; In whole boats and ships, the cavity volume summation of left and right side of a ship wing buoyancy compartment and front deck buoyancy compartment and rear deck buoyancy compartment can be greater than 20% of the specified cargo-carring total displacement of volume of this ship, the cavity volume of left and right side of a ship wing buoyancy compartment and front deck buoyancy compartment, rear deck buoyancy compartment and middle deck buoyancy compartment and greater than 60% of the specified cargo-carring total displacement of volume of this ship.

The ship that the utility model provides is in cruising, about the side of a ship wing buoyancy compartment in two sides of a ship outsides on the water surface, when stormy waves beat during the ship wigwag motion, the side of a ship wing buoyancy compartment in two sides of a ship outside begins to touch water, produce buoyancy, come the balance hull to wave the pressure that makes ship desire to turn over this, tilt upward because of the bottom surface of side of a ship wing buoyancy compartment simultaneously, so when hull restores balance under the effect of side of a ship wing buoyancy compartment, the side of a ship wing buoyancy compartment bilge can not produce " vacuum " phenomenon, can successfully leave the water surface and recover normal navigation rapidly.Water sinks in case this ship meets accident into, after sinking to side of a ship wing buoyancy compartment and the water surface contact, the total weight of the buoyancy that is produced because of side of a ship wing buoyancy compartment etc. during greater than shipful, so boats and ships can continue to swim on the water surface under the lifting of side of a ship wing buoyancy compartment and front deck, rear deck and middle deck buoyancy compartment, provide condition for rescuing distress personnel and goods.Why any object can float on the surface, and is because its displacement of volume greater than weight itself, when such object is under water, or does not absorb moisture and promptly do not increase deadweight, so float on the surface forever; Or absorption moisture, i.e. deadweight will increase gradually, equate that when deadweight increases to buoyancy then object begins to sink, if can stop object to absorb moisture, can delay its sinking.In buoyancy compartment, fill the solid foamed material, be that it can stop water not bleed in a large number when buoyancy compartment is also crashed through into water, even and the solid foamed material after water logging bubble sennight fully absorbs water, its deadweight is generally also super only 10%, Gu can guarantee that still this ship floats on the surface.

The ship that has buoyancy compartment that the utility model provides can be filled the low density solid expanded material in side of a ship wing buoyancy compartment and front deck, rear deck and middle deck, can reduce bleeding of water and reduce the increase of its deadweight after the ship breakage.In the interlayer of the ceiling frame of ship, also can fill described expanded material.When the serious overload of boats and ships or when impaired, when himself total weight began to sink greater than its buoyancy, this ship also was that level is sunk, and can not overturn, and can protect effectively like this that institute's cargo can not run off on the ship, for salvaging is in the future provided convenience.The boats and ships of submerged are because current or when manually alleviating load on the ship to its rated value, hull will emerge under the effect of lifting of the directional tagging of the solid foamed material in the ceiling frame interlayer and front, rear, left and right buoyancy compartment self-equalizing, or also do not drop to rated value, when total weight only is lower than at that time total displacement of volume buoyancy of this ship, promptly begin the balance come-up.

Ship that has buoyancy compartment that the utility model provides and the collision of its thing cause on fire, and the expanded material in the buoyancy compartment is heated the contraction fusing, in case buoyancy compartment breakage at this moment, water will pour in, and ship can very fast sinking.For fear of the generation of this situation, can in described buoyancy compartment and ceiling frame interlayer, be provided for pipeline and steam self-draining valve to wherein water filling, be convenient to the cooling solid expanded material.

The ship that has buoyancy compartment that the utility model provides, owing to be provided with buoyancy compartment, and in the interlayer of buoyancy compartment and ceiling frame, fill the solid foamed material, also in buoyancy compartment and in the interlayer of ceiling frame, water injecting pipeline and automatic exhaust valve are set simultaneously, can do not thrown no matter run into great stormy waves under sail yet, after the bilging that meets accident is forced to suspend, the sinking of also can not overturning, even surpassing its buoyancy, the weight of ship sinks, also be that balance is sunk, and when ship weight returns to its rated load, can float the water surface again automatically, guarantee the safety of ship's staff's goods.

Effect of the present utility model and being also advantageous in that is hit into and all can not sunk, do not turn under the situation such as water and presence of fire, to guarantee ship's staff and cargo security.
