Description

一种船舶压载舱水流冲击系统 技术领域
本发明涉及船舶技术领域，尤其涉及一种船舶压载舱水流冲击系统。
背景技术
在运送原油或集装箱的货船中设有用以确保船舶在航行时船体的稳定性的压载舱。通常在没有装载原油等货物时在压载舱内注满压载水，而当需要装入原油或集装箱等时则将压载水排出，从而调整船体浮力以使船体稳定。
尤其对于大型运输船舶，其压载水量甚至高达10万吨，某种情况下(尤其船舶在港口、入海口等海域)，船舶注入的压载水含有大量的泥沙，经过长时间航行后，泥沙沉淀在压载舱底部形成坚硬、厚实的淤泥层，从而导致清理压载舱淤泥需要花费大量的人力、物力及时间，延长了船舶在港时间，降低了经济效益。
发明内容

具体实施方式
下面结合附图和实施方式进一步说明本发明的技术方案。可以理解的是，此处所描述的具体实施例仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部。
实施例1
如图1和图2所示，本实施例提供一种船舶压载舱水流冲击系统，包括由多个第一喷水嘴111组成的第一喷水嘴组11、由多个第二喷水嘴121组成的第二喷水嘴组12、以及水泵13；其中，第一喷水嘴组11设置于压载舱10的侧壁， 第二喷水嘴组12设置于压载舱10的舱底；水泵13的进水端与水源连通，水泵13的出水端为第一喷水嘴组11和第二喷水嘴组12供水。
压载舱10内注入压载水时，开启第一喷水嘴组11和第二喷水嘴组12，每对第一喷水嘴111和第二喷水嘴121喷出的水流可对压载水中的泥沙形成水流扰动，能有效防止泥沙沉淀在压载舱10底部形成淤泥，降低了人工清理淤泥所需要的时间，减少了船舶的在港时间。
在本实施例中，第一喷水嘴组11的数量为两组，并分别设置在压载舱10的两相对侧壁上；第二喷水嘴组12的数量为一组，第二喷水嘴组12有两种设置形式，一种如图2所示，第二喷水嘴组12设置在压载舱10的舱底的中部；另一种图中未示出，多个第二喷水嘴121在舱底呈螺旋方式排布，优选的，多个第二喷水嘴121沿第二喷水嘴组12形成的螺旋线的切线方向倾斜。
进一步的，第一喷水嘴组11邻近舱底设置，第一喷水嘴111可垂直于舱壁设置，也可以相对于舱壁倾斜设置。
进一步的，在本实施例中，水泵13为消防泵，消防泵的出水端通过第一管路14为第一喷水嘴组11和第二喷水嘴组12供水，消防泵的出水端还连接有用作消防的第二管路15；第一管路14和所述第二管路15上均设置有阀门16。当需要对压载舱10内的压载水形成水流扰动时，打开第一管路14上的阀门16，关闭第二管路15上的阀门16即可；当出现船舶起火等事故时，打开第二管路15上的阀门16，关闭第一管路14上的阀门16，即可用于灭火操作。
阀门16可以为自动阀门，例如遥控阀，遥控阀具有工作平稳可靠、流量大；阀瓣快开慢闭、无水锤冲击(关闭时间可调)；止回密封效果好、使用寿命时间长；安装维修方便的优势。
阀门16也可以为手动阀门，例如球阀，球阀具有结构简单紧凑、密封可靠、 流体阻力小、操作方便、开闭迅速的优点，并且密封面与球面常在闭合状态，不易被介质冲蚀，易于操作和维修。
实施例2
如图3至图5所示，本实施例提供一种船舶压载舱水流冲击系统，为了简便起见，仅描述实施例2与实施例1的区别点，区别之处在于：在本实施例中，第一喷水嘴组11的数量为两组，并分别设置在压载舱10的两相对侧壁上；第二喷水嘴组12的数量也为两组，两组第二喷水嘴组12在压载舱10的舱底间隔分布，并分别与两组第一喷水嘴组11相对应。
第二喷水嘴组12的设置形式有两种，一种如图3所示，两组第二喷水嘴组12均与舱底垂直布置；另一种如图4所示，两组第二喷水嘴组12均倾斜设置在压载舱10的舱底，且其中一组第二喷水嘴组12的倾斜方向与另一组第二喷嘴组12的倾斜方向相反，倾斜设置的喷嘴可以加大冲洗舱底污泥的力度，且两组倾斜方向相反，可以形成一个循环的冲击水流，加大冲洗力度。
显然，本发明的上述实施例仅仅是为了清楚说明本发明所作的举例，而并非是对本发明的实施方式的限定。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。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
