Problems solved by technology

However, for ships navigating in polar regions, the hull is in direct contact with the ice layer during the voyage, and the seawater tank is directly connected to the seawater suction main pipe. If the seawater is sucked into the main pipe, it will cause the blockage of the ship's pipelines, affect the normal operation of the ship's system, and in serious cases, it will cause equipment failure and cause serious accidents such as ship shutdown and cessation of navigation.

Embodiment 1

[0023] like figure 1 As shown, in this embodiment, a seawater tank structure of a ship according to the present invention includes an upper seawater tank 1 and a lower seawater tank below it, the upper seawater tank 1 is provided with a heating mechanism, and the lower layer A dividing plate 15 is arranged in the seawater tank, and the dividing plate 15 divides the lower seawater tank into the lower first seawater tank 2 and the lower second seawater tank 3, and the lower first seawater tank 2 communicates with the water suction main pipe 9, so The second seawater tank 3 of the lower floor is provided with a water inlet grille 6 on the side bulkhead away from the first seawater tank 2 of the lower floor, and the first seawater tank 2 of the lower floor and the second seawater tank 3 of the lower floor are respectively connected to the first seawater tank 3 of the lower floor. The above-mentioned upper seawater tank 1 communicates.

[0024] The water inlet grille 6 can block t...

Embodiment 2

[0041] This embodiment is basically the same as Embodiment 1, the difference is that: the first heating device includes a rotating shaft and a heating plate arranged on the outer periphery of the rotating shaft, and the rotating shaft is perpendicular to the horizontal plane and connected to the driving mechanism. The heating sheet in this embodiment is installed in the upper seawater tank 1 through a rotating shaft, and is driven to rotate by a driving mechanism to speed up the melting speed of the ice layer.

[0042] Preferably, the heating sheet is a blade arranged at intervals on the outer periphery of the rotating shaft, and the blade is parallel to the horizontal plane. The heating sheet stirs the ice cube layer, which can play the role of crushing ice to a certain extent, so as to further accelerate the melting speed of the ice cube layer .

[0043] In the description herein, it should be understood that the terms "first" and "second" are only used for distinction in de...

Abstract

A seawater chamber structure of a ship, comprising an upper layer seawater chamber (1) and a lower layer seawater chamber under same. A heating mechanism is provided in the upper layer seawater chamber (1). A separator (15) is provided in the lower layer seawater chamber. The lower layer seawater chamber is divided into a first lower layer seawater chamber (2) and a second lower layer seawater chamber (3) by the separator (15). The first lower layer seawater chamber (2) communicates with a water suction header pipe (9). A water inlet grating (6) is provided at the chamber wall at the side of the second lower layer seawater chamber (3) away from the first lower layer seawater chamber (2). The first lower layer seawater chamber (2) and the second lower layer seawater chamber (3) separately communicate with the upper layer seawater chamber (1). The seawater chamber structure of a ship can effectively prevent ice cakes from blocking a seawater pipeline system, and thus can provide safety guarantee for ship sailing in icy zones.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship seawater tank structure. Background technique [0002] With the warming of the global climate, the sea ice in the Arctic Ocean is melting at an accelerated rate. The rich resources in the Arctic region, the important strategic location and the increasingly smooth Arctic shipping lanes have caused more and more ships to shuttle between the two polar regions in recent years. The development of the polar regions in the future will become a new stage for great powers to compete. [0003] Due to the special climate in the polar regions, there are a large number of ice blocks floating on the sea all year round. Compared with conventional ships, ships sailing in the polar regions need to have comprehensive anti-freezing and anti-icing capabilities. Special design is required. The seawater tank structure of the existing conventional ship type usually includes a seawater tank, seaw...
