Abstract
The invention discloses a semi-submersible type launching barge ballast tank watertight bulkhead opening and ventilating structure. The structure comprises a plurality of adjacent ballast tanks, and the side ballast tank is connected with a ventilation pipe. The ventilation pipe comprises a pipe segment arranged on the outer portion of the side ballast tank and a pipe segment arranged in the side ballast tank, ventilation holes are formed in the watertight bulkheads of the other two adjacent ballast tanks, an excess flow check valve is arranged on the upper segment of the ventilation pipe to be communicated with a special tower excess flow ballast tank, a general opening deck is arranged at the uppermost end of the ventilation pipe, and the lower end of the ventilation pipe is connected with a check valve. The structure is simple and reasonable in design, due to the design that the two to three ballast tanks share one ventilation pipe, the technical problem that a main deck clear space is occupied by the semi-submersible type barge ventilation pipe is solved, under the condition of ensuring the normal ventilation, the clear space of the deck is utilized, launching of a large-type ship and a platform structure is achieved, due to the design, the use number of pipe materials and mounting working hours are reduced, and meanwhile cost of valves, accessories and the like is reduced.
Description
Technical field
The present invention relates to a kind of ballast tank watertight bulkhead perforate ventilating structure, be specifically related to a kind of ballast tank watertight bulkhead perforate ventilating structure of semisubmersible launching barge.
Background technology
Semisubmersible launching barge, has water and floating drydock function under other large ship of help, therefore needs larger space, flush deck.Each ballast tank of traditional design need arrange a permeability cell, needs to have arranged a large amount of vent pipe structures, thereby reduced space, flush deck on main deck, can not realize the function of subdominant chord of large ship and platform structure.
Summary of the invention
Goal of the invention: the object of the invention is in order to solve deficiency of the prior art, provide a kind of simple in structure, realized main deck clear space, saved the semisubmersible launching barge ballast tank watertight bulkhead perforate ventilating structure of the use amount of set-up time and pipe fitting consumptive material simultaneously.
Technical scheme: a kind of semisubmersible launching barge ballast tank watertight bulkhead perforate ventilating structure of the present invention, comprise adjacent some ballast tanks, wherein the first ballast tank is connected with permeability cell, described permeability cell comprises and is located at the outside pipeline section of ballast tank with the inner pipeline section of ballast tank, on the watertight bulkhead of described the first ballast tank and the second ballast tank, the second ballast tank and the 3rd ballast tank, be respectively equipped with breather hole, the epimere of described permeability cell is partly connected with excess flow check valve, and the lower end of described permeability cell is connected with boiler check valve.
As optimization, the quantity of described ballast tank is 2～3.
As optimization, described excess flow check valve is located in overflow cabin.
As optimization, described permeability cell is connected by crossing cabin part with watertight wall.
As optimization, described breather hole total total area be not less than 1.25 times of ballast filling tube cross-sectional area.
As optimization, the cross-sectional area of described permeability cell is not less than 1.25 times of ballast filling tube cross-sectional area.
As optimization, the inner pipeline section end-to-end distance of described permeability cell ballast tank is 100mm from the distance at ballast tank top.
As optimization, described permeability cell causes safety deck 760mm at least above.
As optimization, the inner pipeline section of described permeability cell ballast tank extends to any one ballast tank in the first ballast tank, the second ballast tank or the 3rd ballast tank.
As optimization, described breather hole is located at the top of watertight bulkhead.
Beneficial effect: the present invention is simple in structure, reasonable in design, by 2～3 ballast tanks, share the design of a permeability cell, solved the technical barrier that existing ship permeability cell takies main deck space, in the situation that assurance is normally ventilative, thereby utilized the clear space on deck, realized the lower water of large ship and platform structure, this design has reduced use amount and the installation work-hour of tubing, has reduced the costs such as valve, annex simultaneously.
