Abstract
The invention discloses a ballast tank ventilation pipeline, and relates to the technical field of ship design. The ballast tank ventilation pipeline comprises a ventilation box close to ballast tanks, the ventilation box is in a long strip shape, and the length direction of the ventilation box is arranged in the center axis direction of a ship. The length of the ventilation box is at least twice longer than the lengths of the two ballast tanks distributed in the center axis direction. The ventilation box is connected with the ballast tanks through ventilation pipes. The front end and the rear end of the ventilation box are each provided with a ventilation header pipe extending to a main deck. The ballast tank ventilation pipeline solves the problems that the number of existing ventilation pipes is too large and the weight of the pipeline is too high.
Description
Technical field
The present invention relates to Ship Design Technology field, particularly relate to a kind of ballast tank and to breathe freely pipeline.
Background technology
Ballasting system is widely used in various boats and ships and offshore platform.Operation is carried by performing ballast/row to the ballast tank being arranged at each position in hull or platform lower structure, regulate the steady and safe metacentric height of drinking water and hull vertical, horizontal, be conducive to improving boats and ships and the stability of offshore platform when sailing in ballast or towage, reduce shipbody deformation, in order to avoid cause excessive moment of deflection and shearing force, reduce ship vibration and improve empty cabin navigability, thus avoiding the fierceness in stormy waves to wave.The venting system be communicated with air is set in ballast tank, makes ballast tank carry out ballast or arrange the balance keeping cabin internal pressure when carrying operation.
It is all at top, the cabin of each ballast tank extraction permeability cell that existing ballast tank is breathed freely, and is caused by permeability cell and build region rear wall or chimney.But, the problems such as above-mentioned design causes pipeline One's name is legion, and pipeline is long, the defect such as cause piping layout difficulty and light weight is large.
Summary of the invention
The object of the invention is to propose a kind of ballast tank to breathe freely pipeline, the layout of pipeline can be simplified, alleviate the weight of pipeline, can light weight be reduced, increase charging burden.
For reaching this object, the present invention by the following technical solutions:
A kind of ballast tank is breathed freely pipeline, comprise the ventilative case arranged near ballast tank, described ventilative case is strip shape, its length direction is arranged along the direction, axis of boats and ships, the length of described ventilative case is at least longer than the length of two ballast tanks of direction, described axis arrangement, described ventilative case is connected by permeability cell with between ballast tank, and the front-end and back-end of described ventilative case are respectively arranged with ventilative house steward, and described ventilative house steward extends on main deck.
Further technical scheme, the rear end of described ventilative case is near the front end of the ballast tank of described boats and ships afterbody, and the front end of described ventilative case is near the rear end of the ballast tank of foremost part of ship.
Further technical scheme, the rear end of described ventilative case and the ballast tank antetheca of described boats and ships afterbody are positioned on the same cross-sectional plane of described boats and ships, and the front end of described ventilative case is near the cabin of described boats and ships.
Further technical scheme, described ballast tank is divided into larboard ballast tank, starboard ballast tanks and middle ballast tank, described boats and ships are provided with two ventilative casees along wherein axisymmetrical, be respectively breathe freely case and starboard of larboard to breathe freely case, described larboard ballast tank and middle ballast tank are communicated with by permeability cell and described larboard case of breathing freely, and described starboard ballast tanks and middle ballast tank are communicated with by permeability cell and described starboard case of breathing freely.
Further technical scheme, the shape of cross section of described ventilative case is rectangle frame-type.
Further technical scheme, is provided with shutoff valve between described ventilative house steward and described ventilative case.
Further technical scheme, described ventilative case is connected with described ballast tank by shortest path by described permeability cell.
Beneficial effect of the present invention:
The ballast tank that the present invention proposes is breathed freely pipeline, comprise ventilative case, and be communicated with the permeability cell of ventilative case and ballast tank, because multiple ballast tank can be communicated with ventilative case by permeability cell simultaneously, ventilative case is strip shape, all shorter with the vertical distance of multiple ballast tank, therefore by shorter permeability cell, ballast tank can be communicated with ventilative case, ventilative case then extends to main deck by the ventilative house steward on it, overcome the problem that each ballast tank connected in the past permeability cell all needs to extend to main deck and the pipeline that causes is too much, simplify pipeline, alleviate pipe weight, the cargo capacity of boats and ships can be increased.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
" front " and " afterwards " in the present invention refers to respectively and points to ship's head for " front ", and pointing to stern direction is " afterwards ".
Embodiment 1
As Figure 1-3, a kind of ballast tank is breathed freely pipeline, comprise the ventilative case 1 arranged near ballast tank, ventilative case 1 is strip shape, its length direction is arranged along the direction, axis of boats and ships, the length of ventilative case 1 is at least longer than the length of two ballast tanks of direction, axis arrangement, preferably, the rear end of ventilative case 1 is near the front end of the ballast tank of boats and ships afterbody, the front end of ventilative case 1 is near the rear end of the ballast tank of foremost part of ship, further preferably, the ventilative rear end of case 1 and the ballast tank antetheca of boats and ships afterbody are positioned on the same cross-sectional plane of boats and ships, the front end of ventilative case 1 is near the position, cabin 7 of boats and ships, above two kinds of settings can ensure the demand of breathing freely, the appropriate design of structure can be ensured again.
Ventilative case 1 is connected by permeability cell 2 with between ballast tank, and ventilative case 1 is connected with ballast tank by shortest path by permeability cell 2, to reduce pipeline, alleviates pipe weight; The front-end and back-end of ventilative case 1 are respectively arranged with ventilative house steward 3, ventilative house steward 3 extends on main deck, overcome each ballast tank in the past all by problem that the pipeline that permeability cell 2 direct channel main deck causes is too much, breathe freely and be provided with shutoff valve 8 between house steward 3 and ventilative case 1, ventilative case 1 can be controlled and be communicated with extraneous.
