The exemplary embodiment for embodying the utility model features and advantages will describe in detail in the following description.It should be understood that
Be that the utility model can have various variations in different embodiments, all do not depart from the model of the utility model
It encloses, and the descriptions and illustrations are essentially for illustration purposes, rather than to limit the utility model.
Fig. 1 is shown comprising the partial structure diagram according to the drill ship of the wave subduer of the utility model embodiment.
As shown in Figure 1, be mounted on the hull 2 of drill ship being located in moon pool 1 according to the wave subduer 3 of the utility model embodiment,
To play the role of the wave making resistance reduced drill ship during navigation, reduce impact of the seawater to the side wall construction of moon pool 1.
The main composition part of wave subduer is washboard.Under job state, i.e., play the role of wave resistance in washboard
Under state, generally washboard is obliquely installed relative to hull, so that wave impacts on washboard and prevented from obliquely downward
Specific structure or material in wave plate slow down, mitigate impact force.In the prior art, washboard is generally fixedly provided in ship
On body, i.e., washboard is unadjustable relative to the tilt angle or orientation of hull.This, which causes to work as, needs the object of such as preventer
Body is very inconvenient when transferring in moon pool 1 from hull 2, for example, it may be desirable to remove washboard, or may need first to cross
Higher washboard could be transferred in moon pool.
The embodiments of the present invention provide a kind of rotatable wave subduer, so that without removing washboard or increasing object
Body can transfer object to moon pool from hull.
It is illustrated below with reference to the embodiment of Fig. 2-4 pairs of wave subduers 3.
