Abstract
The invention relates to a ship anti-sinking ejecting system, belonging to ship life keeping technical field, comprising two thermal insulating storage cylinder, two piston pumps, air compressor, mixing space, main pipeline and branched pipe, insulating support, insulating washer, electric control valve, and control unit, where the two thermal insulating storage cylinders are stored with isocyanate and polyether polyalcohol. As water enters in the cabin, the two position pumps the two chemical products in the mixing space. Under the action of high- pressure air, the mixture of the two chemical products form hard polyurethane foamed plastic to enter into the main pipeline. The control unit controls to open the branched pipe of some damaged cabin so as to eject the hard polyurethane foamed plastic into the cabin to resist the entering water. As the ship holds combustible and explosive articles, it adds dimethyl phosphate acid by 10% wt to the polyether polyalcohol. Even if water enters into all cabins, it can keep the ship unsinkable and thus has remarkable social and economic benefits.
Description
Affiliated technical field
What the present invention relates to is a kind of injection system, and particularly a kind of marine unsinkable injection system that is suitable for when breakage takes place ship's space belongs to boats and ships survivability and keeps technical field.
Background technology
Present all kinds of boats and ships when destruction so that cabin water inlet take place the hull of drinking water part, except with the urgent draining of water pump, there is no other cost-effective emergent anti-means of sinking.And the water pump draining is subjected to the position limit of bailing outlet, often can not in time discharge and leak, so that boats and ships generation sinking accident.The boats and ships that have adopt the watertight division design, when excessive and hull breach is long at damaged area, can not stops the quick water inlet and the sinking of hull, so that cause the massive losses of lives and properties.In the prior art, application number is called the patent of invention of " heavy method reaches not shipwreck to make boats and ships " for the CN00110741.0 name, it is filled soft polymerization Charge between the inside and outside wall of boats and ships, it needs boats and ships that an osed top cabin body is arranged and special-purpose inside and outside wall is set, and is not easy to the practical application on the engineering; Application number is called the patent of invention of " the buoyancy aid water tank is shipwreck not " for the CN03140348.4 name, be to manufacture the buoyancy aid water tank with high-strength light materials such as glass-felt plastic and plastics steel, periphery at hull is thickeied, also dislike complex structure with the not shipwreck that several casings that are added with foam lightweight material formations are set, involve great expense; Application number is called the patent of invention of " the light body material of anti-shipwreck filling cabin method " for the CN03133202.1 name, be that light body material is filled in the relevant watertight compartment of boats and ships, water can't be poured into watertight compartment when ship was leaked, and this method need be changed hull construction, and economy and practicality are relatively poor.
Summary of the invention
Deficiency and defective in order to overcome prior art the invention provides a kind of marine unsinkable injection system.This system can not only meet an urgent need easily and flexibly when boats and ships generation leakage loss and adopt, and the structure of boats and ships itself is not made any changes, do not have any requirement, can come into force the state that boats and ships cannot be in heavyly under urgent situation fast.
The present invention realizes by following technical proposals: the present invention includes first insulation storage cylinder, first piston pump, second insulation storage cylinder, second piston pump, air compressor, blending box, trunk line, arm, insulation support, insulating washer, electrically-controlled valve, control unit.First insulation storage cylinder is connected with an inlet point of blending box by the first piston pump, and second insulation storage cylinder is connected with another inlet point of blending box by the second piston pump.The outlet of air compressor is connected with the admission port of blending box, and the discharging opening of blending box is connected with the entrance point of trunk line.Trunk line relies on insulation to be supported and fixed on the suitable position of boats and ships.Trunk line is connected with the arm that leads to each cabin respectively, electrically-controlled valve all is housed on each arm, on electrically-controlled valve and trunk line bonded assembly arm, insulating washer is housed all, makes each arm be connected the unlikely mode of operation that influences electrically-controlled valve of electric current of heating trunk line with the electrically-controlled valve insulation.The mouth of control unit electrically connects with the control end of each electrically-controlled valve respectively.Electrically-controlled valve is opened and closed by the unified control of control unit, to determine the opening and closing state of each arm.The external 110V power supply in the two ends of trunk line makes electric current pass through trunk line, under the effect of electric current and the resistance of trunk line own, trunk line heating with the temperature that keeps pipeline in 5-20 ℃ of scope.Trunk line outer wall wrapping thermal insulating layer avoids the loss of heat and the leakage loss of electric current.In first insulation storage cylinder, deposit isocyanates, in second insulation storage cylinder, depositing the polyether glycol blending ingredients.First insulation storage cylinder and second insulation storage cylinder adopt the electric heating constant temperature attemperator.Isocyanates is stable chemical, and is can long-term storage stand-by; The storage period of polyether glycol blending ingredients is six months, six months need not after should upgrade storage.
When boats and ships generation cabin breakage causes the cabin water inlet, open the electric heating constant temperature attemperator of two insulation storage cylinders immediately, after 3-5 minute, two insulation storage cylinders all can reach desired 20 ± 1 ℃ of temperature, two piston pumps are started working, and two kinds of chemical are pumped into blending box.Simultaneously, air compressor is started working, and air compression to 15Mpa, is fed blending box again.Under the high pressure air effect, the compound of two kinds of chemical forms RPUF, enters trunk line.Simultaneously, control unit is controlled the electrically-controlled valve of damaged cabin arm and is opened, and makes the RPUF in the trunk line spray into the damage and water inflow cabin by this cabin arm.After Polyurethane foam sprayed into the space in damage and water inflow cabin, in the time, cubic expansion 30-40 times, formation density was 22-26kg/m at 45 seconds-75 seconds fibers
3Rigid foam, making whole cabin is that light material is occupied; In the not sticking rapid hardening of time inner foam plastics in 50 seconds-95 seconds subsequently, produce the pressure of 30-50Kpa simultaneously.The foam texture of this RPUF is closed bubble, can not intake in the cavity of foam, to resist the hull water inlet.
The invention has the beneficial effects as follows: adopt this marine unsinkable injection system, original hull structure is not needed to carry out any change, also without any structural restriction; It can use under any urgent situation easily, even all cabins of boats and ships all intake, the damaged area of hull is very big or hull breach when very long, the heavy state that still can keep these boats and ships effectively guarantees the survivability of boats and ships to have remarkable social benefit and economic benefit.
