Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
In the present invention unless specifically defined or limited otherwise, fisrt feature second feature "upper" or "lower"
It may include that the first and second features directly contact, also may include that the first and second features are not direct contacts but pass through it
Between other characterisation contact.Moreover, fisrt feature the "upper" of second feature include fisrt feature second feature just
Top and oblique upper, or first feature horizontal height is merely representative of higher than second feature.Fisrt feature is in the "lower" of second feature
It is directly below and diagonally below the second feature including fisrt feature, or is merely representative of first feature horizontal height less than second feature.
In the description of the present invention unless specifically defined or limited otherwise, term " first ", " second " are only used for describing
Purpose is not understood to indicate or imply relative importance or implicitly indicates the quantity of indicated technical characteristic.As a result,
Define " first ", the feature of " second " can explicitly or implicitly include one or more this feature.
As shown in Figure 1 to Figure 2, the sea water tank of the present embodiment is arranged in ship topside, is internally provided with partition wall 1, separates
Wall 1 includes first partition 11 and second partition 12, and first partition 11 is vertically arranged, the upper end of first partition 11 and sea water tank
Head clearance, one end of second partition 12 are connected to the lower end of first partition 11, and the other end of second partition 12 is connected to sea
The bottom of water tank, first partition 11 and second partition 12 are arranged in angle, keep second partition 12 parallel or approximate with ship plank 5
In parallel, the two sides of first partition 11 and second partition 12 are connect with the side wall of sea water tank.
Deviate from the side of ship plank 5 in partition wall 1, is provided with return pipe 7 and seawater general pipeline 8, seawater general pipeline 8 is located at back
