Description

一种燃油日用舱的溢流结构 技术领域
本实用新型涉及油舱领域，尤其涉及一种燃油日用舱的溢流结构。
背景技术
船舶在极地航行时内外温差较大，液化比较严重，所以油箱会有水，同时在温度降低时，水的溶解性也会相应变小，因此在极地航行的船舶的油箱的含水引发的问题会更加明显。现有的位于机舱上平台的燃油日用舱和燃油沉淀舱均通过单独的溢流管，溢流到机舱底层的燃油溢流舱。现有的设计需要两根溢流管，由于机舱上平台与机舱底层之间的距离较大，同时由于船体自身结构的限制无法铺设直线管道，严重增加了管路的复杂性。而且溢流管路上需要安装可视装置，以便查看是否出现溢流情况。
实用新型内容
本实用新型的目的在于提供一种燃油日用舱的溢流结构，简化了管路的布置，降低了空船的重量。
为达此目的，本实用新型采用以下技术方案：
一种燃油日用舱的溢流结构，包括船体上平台，所述船体上平台上设有燃油日用舱及燃油沉淀舱，所述燃油日用舱与所述燃油沉淀舱之间设有连通管，所述连通管包括竖直管和水平管，所述水平管与所述竖直管相连，所述竖直管位于所述燃油日用舱内，所述竖直管远离所述水平管的一端位于所述燃油日用舱的底部，所述水平管的一端位于所述燃油日用舱内，所述水平管的另一端位 于所述燃油沉淀舱内。
作为优选，所述连通管还包括倒钩管，所述倒钩管位于所述燃油沉淀舱内，所述水平管远离所述竖直管的一端与所述倒钩管相连，所述燃油沉淀舱的侧壁上设有与所述倒钩管相对应的防冲击板。
作为优选，所述防冲击板包括平板和设于所述平板两端的立板，所述平板与所述燃油沉淀舱的侧壁之间设有间隙，所述立板的一端与所述平板相连，所述立板的另一端与所述燃油沉淀舱的侧壁相连。
作为优选，所述燃油沉淀舱远离所述燃油日用舱的一端的侧壁上设有溢流口，所述水平管位于所述溢流口的上方。
作为优选，还包括船体底层，所述船体底层上设有燃油溢流舱，所述燃油溢流舱与所述溢流口之间设有溢流管。
作为优选，所述船体底层与所述船体上平台之间在竖直方向的距离为5米-10米。
作为优选，所述水平管与所述燃油日用舱之间为焊接连接；
和/或，所述水平管与所述燃油沉淀舱之间为焊接连接。
本实用新型的有益效果：当燃油日用舱内的液位高于水平管的位置时，在液体自身重力作用下将燃油日用舱底部的水或者燃油压入竖直管内，水或者燃油再通过水平管流入燃油沉淀舱内。由于水的密度大于燃油的密度，因此水会沉积在燃油日用舱的底部，所以将竖直管的一端设置在燃油日用舱的底部能够有效将燃油日用舱内的水向外排出，解决了燃油日用舱的溢流问题的同时，简化了管路的布置，节省了成本，降低了空船重量。

具体实施方式
下面结合附图并通过具体实施方式来进一步说明本实用新型的技术方案。
如图1-3所示，一种燃油日用舱的溢流结构，包括船体上平台1，船体上平台1上设有燃油日用舱2及燃油沉淀舱3，燃油日用舱2与燃油沉淀舱3之间设有连通管4，连通管4包括竖直管41和水平管42，水平管42与竖直管41相连，竖直管41位于燃油日用舱2内，竖直管41远离水平管42的一端位于燃油日用舱2的底部，水平管42的一端位于燃油日用舱2内，水平管42的另一端位于燃油沉淀舱3内。
具体地，当燃油日用舱2内的液位高于水平管42的位置时，在液体自身重力作用下将燃油日用舱2底部的水或者燃油压入竖直管41内，水或者燃油再通 过水平管42流入燃油沉淀舱3内。由于水的密度大于燃油的密度，因此水会沉积在燃油日用舱2的底部，所以将竖直管41的一端设置在燃油日用舱2的底部能够有效将燃油日用舱2内的水向外排出。
于本实施例中，连通管4还包括倒钩管43，倒钩管43位于燃油沉淀舱3内，水平管42远离竖直管41的一端与倒钩管43相连，燃油沉淀舱3的侧壁上设有与倒钩管43相对应的防冲击板5。
进一步的，为了防止水或者燃油流向燃油沉淀舱3时影响燃油沉淀舱3内液体的液位的稳定性，设置倒钩管43，倒钩管43将液体引向燃油沉淀舱3的侧壁，液体随着燃油沉淀舱3的侧壁缓缓向下流，对燃油沉淀舱3内的液体无剧烈冲击，也即使得燃油沉淀舱3内液体的液位能够发生相对稳定的变化。同时，为了避免流入燃油沉淀舱3内的水或燃油对燃油沉淀舱3的侧壁的冲击进而导致燃油沉淀舱3的侧壁发生俯视，设置防冲击板5，从倒钩管43流出的液体直接流向防冲击板5，不与燃油沉淀舱3的侧壁发生直接冲击。
于本实施例中，防冲击板5包括平板51和设于平板51两端的立板52，平板51与燃油沉淀舱3的侧壁之间设有间隙，立板52的一端与平板51相连，立板52的另一端与燃油沉淀舱3的侧壁相连。
进一步的，平板51与燃油沉淀舱3的侧壁之间设有间隙，有效减少平板51与燃油沉淀舱3的侧壁之间的力传递。
于本实施例中，燃油沉淀舱3远离燃油日用舱2的一端的侧壁上设有溢流口，水平管42位于溢流口的上方。当燃油沉淀舱3内的液位高于溢流口时，液体从溢流口流出。
于本实施例中，还包括船体底层6，船体底层6上设有燃油溢流舱7，燃油溢流舱7与溢流口之间设有溢流管8。具体地，燃油沉淀舱3内的液体通过溢流 管8进入燃油溢流舱7。
于本实施例中，船体底层6与船体上平台1之间在竖直方向的距离为5米-10米。
于本实施例中，水平管42与燃油日用舱2之间为焊接连接；水平管42与燃油沉淀舱3之间为焊接连接。
显然，本实用新型的上述实施例仅仅是为了清楚说明本实用新型所作的举例，而并非是对本实用新型的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型权利要求的保护范围之内。
