The utility model relates to a kind of deck bulwark drainage hole structures, including deck bulwark, the bottom of the deck bulwark offers several drainage holes side by side, the baffle that one shape is coincide with drainage hole is respectively installed in each drainage hole, the baffle is hinged on the bulwark of deck by the shaft that both ends are installed in the horizontal direction, and the bottom inside of the drainage hole is installed with the block that anti-baffle plate is overturn to inboard.The height of the drainage hole is 500mm.The shaft is hinged on the inside of deck bulwark.It is connected between two shafts at the baffle both ends by stiffener plate.The quantity of the block is two pieces, is symmetrically distributed in the both ends of drainage hole bottom.The position of the drainage hole is between the adjacent strong frame of hull.The deck bulwark drainage hole structure is suitable for towing/anchor handling/supply vessel.The utility model guarantees displacement, improves drainage efficiency under the premise of meeting bulwark structural strength, and solves the problems, such as that inwelling hinders deck ponding to exclude.

Description

A kind of deck bulwark drainage hole structure

Technical field

The utility model relates to a kind of deck bulwark drainage hole structures, belong to ship deck technical field of drainage.

Background technique

Offshore oil and gas field probing, mining operations mostly use floating or fixed platform to carry out, and supply the resource of platform The work such as give, safeguard often completed by towing/anchor handling/supply vessel.Since marine environment, weather are complicated and changeable, to the supply to platform Upkeep operation often carries out under severe sea condition, suddenly, and with strong wind due to unrestrained high, stream, leads to ship motion intense, operation Deck is easy for submerge in water with ship movement, in addition sea laps, and deck plane will form a large amount of seawater accumulation, wet Sliding deck causes crewman's task difficulty to greatly improve, and even relates to life security.

In order to exclude work deck ponding, it will usually drainage hole be arranged in the deck bulwark bottom of topside, shaken in ship During pendulum, seawater discharges into sea via drainage hole.As shown in connection with fig. 1, the bulwark drainage hole of conventional design, in order to consider Bulwark structural strength, general height are no more than 200mm, and in order to increase displacement, the aperture length of conventional design can be longer, still Its disadvantage formally will appear when a large amount of ponding of deck plane pour into drainage hole together as hull waves due to height limitation Draining reflux, draining not in time the phenomenon that, in addition, due to tapping do not have it is any block, when ship generate big amplitude rolling after, Deck plane can be swarmed there is a situation where unilateral seawater is flowed backward by drainage hole, be less useful for deck drainage.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of deck bulwark drainage hole structures, can in time simultaneously Quickly discharge deck ponding, while external inwelling problem can be prevented again.

To solve the above-mentioned problems, the technical solution adopted in the utility model is as follows:

A kind of deck bulwark drainage hole structure, including deck bulwark, the bottom of the deck bulwark offer several side by side Drainage hole respectively installs a shape in each drainage hole and baffle that drainage hole coincide, the baffle by both ends in the horizontal direction The shaft of installation is hinged on the bulwark of deck,

The bottom inside of the drainage hole is installed with the block that anti-baffle plate is overturn to inboard.

Further, in order to increase displacement, the height of the drainage hole is 500mm.

Further, in order to reduce corrosion of the seawater to shaft, the shaft is hinged on the inside of deck bulwark.

Further, it is connected between two shafts at the baffle both ends by stiffener plate.

Further, the quantity of the block is two pieces, is symmetrically distributed in the both ends of drainage hole bottom.

Further, the position of the drainage hole is between the adjacent strong frame of hull.

Further, the deck bulwark drainage hole structure is suitable for towing/anchor handling/supply vessel.

Compared with prior art, the utility model has the beneficial effects that changing existing strip hole into multiple drainage holes simultaneously The mode of column effectively increases the gross area of drainage hole, meets the requirement for increasing deck drainage amount；By can outboard rotate opening Baffle and block cooperation, realize that deck ponding can be flowed out from drainage hole, and when baffle is by seawater hydraulic gyration, Due to the block being arranged in aperture lower end inside, baffle is prevented to continue to overturn back towards inboard, so that external dynamic sea is kept off by baffle Can not firmly it flow backward.Realize water flow can only one-way flow, can be effectively prevented inwelling hinder deck ponding exclusion；Because adopting It is arranged side by side with multiple drainage holes, when the height of drainage hole is added to 500mm, it still can satisfy the requirement of bulwark structural strength. Drainage hole and every grade strong frame position one-to-one correspondence, not only ensure that displacement and drainage efficiency, but also to be able to satisfy side of a ship wall construction strong in this way The requirement of degree is particluarly suitable for using on the ship of operation under severe sea condition, weather environment.

Specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It is said according to following Bright, the purpose of this utility model, technical solution and advantage will be apparent from.It should be noted that described embodiment is this The preferred embodiment of utility model, instead of all the embodiments.

In conjunction with shown in Fig. 2 to Fig. 5, a kind of deck bulwark drainage hole structure, including deck bulwark 2, the deck bulwark 2 Bottom offers several drainage holes 1 side by side, and the baffle 3 that a shape is coincide with drainage hole, the gear are respectively installed in each drainage hole 1 Plate 3 is hinged on deck bulwark 2 by the shaft 4 that both ends are installed in the horizontal direction, and the bottom inside of the drainage hole 1 is installed with The block 5 that anti-baffle plate 3 is overturn to inboard.The quantity of the block 5 is two pieces, is symmetrically distributed in the both ends of 1 bottom of drainage hole.

Due to the form using multiple drainage holes, the height of the drainage hole 1 can increase to 500mm, while can expire again The requirement of sufficient bulwark structural strength.

The shaft 4 is preferably hinged on the inside of deck bulwark 2.By adding between two shafts at 3 both ends of baffle Strengthening tendons plate 6 connects.

As shown in connection with fig. 6, the position of the drainage hole 1 is between the adjacent strong frame 7 of hull.

The deck bulwark drainage hole structure is particularly suitable for towing/anchor handling/supply vessel.

The above is only the description explanation of the preferred embodiment in the utility model, not to scope of protection of the utility model Restriction, it is clear that anyone skilled in the art based on the above embodiment, can readily occur in replacement or variation to obtain Other embodiments, these, which should all cover, is within the protection scope of the utility model.
