Abstract
The invention discloses grand new design of large ocean vessel capable of effectively reducing silt accumulation in a ballast tank. The improved design of the novel vessel is that: the traditional ballast tank is divided into a side ballast tank and a double-bottom ballast tank, and a special mud-containing water ballast tank is arranged; silt removing drain holes are formed on the longitudinal beam at the bottom in the ballast tank in a staggered manner; and a quick joint for manually flushing the ballast tank is arranged. According to the invention, the silt accumulation area and accumulation amount in the ballast tank of the large vessel are effectively reduced, the carrying capacity of vessel is remarkably increased, the navigation risk of the vessel is reduced, and the economic benefits in vessel operation are increased.
Description
Technical field
The present invention relates to a kind of ballast tank design of large ship, be specially the brand-new design of the anti-mud type ballast chamber of large ship.
Background technology
Ballast tank mud problem is a global difficult problem, because marine site, part harbour quantity of sand and mud is big, silting is serious unusually in the ballast tank.The operation of each flight number ballast water of large ship all will be in ballast tank under the accumulation tens even hundreds of tons mud, and these mud are difficult to be discharged to outboard with ballast water.Accumulate over a long period, the mud in several years rear decks even reach the height of bottom skeleton causes the decline of boats and ships loading capacity, and operating cost increase.The position that has mud to pile up simultaneously again can't be checked through defectives such as burn into fold, flexing or fracture, has increased safety of ship hidden danger.Therefore the deposition that reduces mud in the ballast tank has become new ship design-calculated inexorable trend.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the serious problem of present large ship ballast tank silting, provide a kind of and can effectively reduce the anti-mud type ballast chamber of large ship that mud is piled up in the ballast tank.
Technical scheme: the anti-mud type ballast chamber of large ship of the present invention; Its objective is such realization: a kind of large ship anti-mud type ballast chamber; At first traditional ballast tank is repartitioned, each ballast tank is divided into side ballast tank and double bottom ballast tank at the shelf plate place because boats and ships double bottom part skeleton is more in length and breadth; Mud is easy to pile up, and therefore can in the boats and ships shipping, reduce the use of double bottom ballast tank as far as possible.Through calculating, when whole side ballast tanks of boats and ships and ballast tank ballast of the dual end, middle part, can satisfy the basic demand of ballast for cruising navigation, thereby effectively reduce mud alluvial scope and siltation volume.In view of double bottom ballast tank place complex structure; The characteristics of mud alluvial very easily; This novel ship is again in standard and intensity allowed band, and every rib is arranged the elliptic flow water hole about 4 or 5 150mm * 75mm on the vertical alow bone in scope, and with adjacent vertical bone on the discharge orifice dislocation arrange.Utilize the rolling of boats and ships self, make bottom water flow produce turbulent flow, drive the mud of deposition.Through actual Sectional Test checking, the discharge orifice that dislocation is arranged can obviously increase the scope of washing away mud, and effect is remarkable, and only the topside turn of the bilge still has part mud to pile up.To being difficult to lean on the mud of self removing in the turn of the bilge and the top side tank, this novel ship is arranged the quick coupling of some at each ballast tank.In the time of ballast tank of ship sky cabin, utilize the fire water of boats and ships, through fire hose belt flushing ballast tank, thereby realize removing mud and washing of tanks.
Beneficial effect: the present invention has improved the deposition of mud in the ballast tank greatly, reduces the extra load carrying ability of each flight number boats and ships, has improved the transport power of boats and ships, greatly reduces operating cost; On the other hand, be accompanied by coming into force of ballast water treatment pact, the design can reduce the ballast water treatment amount, has practiced thrift the boats and ships spending to a great extent.

The specific embodiment
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
The anti-mud type ballast chamber of a kind of large ship comprises different ballast freight spaces 1, and each ballast freight space 1 is separated at shelf plate 2 places, and traditional ballast tank is divided into side ballast tank 3 and ballast tank of the dual end 4.The elliptic flow water hole 6 of every rib separation 4 or 5 150mm * 75mm in the scope on the bottom longitudinal 5, and discharge orifice 6 is arranged with adjacent vertical bone 5 dislocation.Artificial flushing is set with quick coupling 7 at the side ballast tank 3 and the turn of the bilge.
Claims (4)
1. the anti-mud type ballast chamber of large ship comprises different ballast tank freight spaces (1), it is characterized in that: each ballast tank freight space (1) is located to separate at shelf plate (2), and traditional ballast tank is divided into side ballast tank (3) and ballast tank of the dual end (4).
2. the anti-mud type ballast chamber of large ship according to claim 1; It is characterized in that: in standard and intensity allowed band; The vertical bone (5) of ballast chamber bottom is gone up every rib and in scope, is arranged 4 or 5 discharge orifices (6), and discharge orifice (6) are arranged with adjacent vertical bone (5) dislocation.
3. the anti-mud type ballast chamber of large ship according to claim 2 is characterized in that: said discharge orifice (6) are oval-shaped, and major axis is 150mm, and minor axis is 75mm.
4. according to claim 1 or the anti-mud type ballast chamber of 2 or 3 described large ships, it is characterized in that: artificial flushing is set with quick coupling (7) at the side ballast tank (3) and the turn of the bilge.
