Description

极地甲板运输船 技术领域
本发明涉及船舶设计技术领域，具体涉及一种极地甲板运输船。

具体实施方式
为使本发明解决的技术问题、采用的技术方案和达到的技术效果更加清楚，下面将结合附图对本发明实施例的技术方案作进一步的详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明的描述中，除非另有明确的规定和限定，术语“相连”、“连接”、“固定”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域 的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1和图2所示，于本实施例中，本发明的一种极地甲板运输船，包括主船体1、位于所述主船体1两端的船艏2和船艉3，所述船艏2的外飘4与水平面的夹角为a，其中，a＝13-25°。通过将船艏2的外飘4与水平面的夹角a设计为13-25°，使极地甲板运输船在极地区域航行时，船艏2的外飘4可连续挤压冰，将冰块破除，破冰遇到的阻力小，不需要使用破冰船在前方破冰即可在较大载重航行的过程中实现快速破冰，而常规的破冰船需要“爬”到冰上，利用船舶自身的重力将冰压坏，破冰阻力大，前进缓慢。
本实施例中，外飘4与水平面的夹角a可以为13-25°中的任意角度，例如13°、18°、19°、25°，外飘4在该角度下时，对极地甲板运输船进行模拟实验，实验结果参见表1：
表1
外飘角度 航速 功率 破冰厚度 载重
13° 2节 8.2兆瓦 1.25米 2.8万吨
18° 2节 8.0兆瓦 1.50米 2.8万吨
19° 2节 8.2兆瓦 1.35米 2.8万吨
25° 2节 8.4兆瓦 1.30米 2.8万吨
备注：2节航速＝3.704公里/小时。
实验结果表明，在相同的航速和载重的情况下，外飘与水平面的夹角a为13-25°之间时，极地甲板运输船模拟运行时所需要的功率均较小，破冰厚度也达到实际冰层厚度；其中，夹角a为18°时，极地甲板运输船模拟运行时所需要的功率最小，破冰的厚度最厚，即夹角a＝18°时，极地甲板运输船破冰受到的阻力最小。
当主甲板上装载用于载货的模块5时，不方便人员在主甲板上行走，同时，在寒冷区域航行时，由于主甲板面结冰，人员通行比较危险。为解决该技术问题，本实施例在主船体的压载舱6内设置有安全通道7，如图3所示，所述安全通道7贯穿所述船艏2和船艉3，所述安全通道7包括人行通道71，人行通道71的尺寸可供人员通过。在现有的船舶中还没有出现过在压载舱内设置供人员通行的人行通道71，人员通常在甲板面行走或施工，本实施例将人行通道71设置在压载舱6内，可以使人员的通行不受极地甲板运输船外部的恶劣环境的影响。
为保证人员在人行通道71内行走的舒适性，人行通道71内还设置有蒸汽加热管，且所述人行通道71沿其长度方向的侧壁上设置有绝缘隔热层，防止热扩散至压载水中。
优选地，所述人行通道71内设置有温度传感器，所述蒸汽加热管与蒸汽发生器装置连接，所述蒸汽加热管设置有压力传感器，所述温度传感器、所述压力传感器及所述蒸汽发生器装置上的电磁阀均与控制器电连接，所述控制器控制所述电磁阀选择性开启；当所述人行通道71内的温度传感器检测的温度达到设定值时，或者，所述压力传感器检测到蒸汽加热管内的压力达到设定值时，所述控制器控制所述电磁阀自动关闭，避免人行通道71过热或者蒸汽加热管因压力过大而爆裂。
本实施例中，安全通道7还包括管路通道72，管路通道72设置在所述人行通道71的踩踏板下方，管路通道72内可以布置管道和电线，避免管道和电线直接泡在压载水中，延长管道和电线的使用寿命。
本实施例将管路通道72与人行通道71集成在一块，节省了船舶舱室的空间，避免穿舱所引起的繁琐设计，优化了极地甲板运输船的整个布局设计，降 低了船舶的建造成本。
为进一步优化管路布置及提高传播上工作人员生活和工作的舒适性，本实施例的压载舱6内靠近其两侧分别设置有一个所述安全通道7。
作为本发明优选的实施方式，所述船艏2设置有锚机以及用于保护所述锚机的保护罩8，所述保护罩8的一侧开设有供人员进出的门。具体地，保护罩8与主甲板焊接在一起，以保护锚机免受海水、雨雪等影响，防止锚机积冰，保证锚机在寒冷地区正常工作。
沿靠近所述船艉3的方向，如图4所示，所述保护罩8的横截面积逐渐增大，以减小极地甲板运输船前进时受到的阻力。
本实施例中，所述主甲板上可拆卸设置有用于居住的居住集装箱9，所述居住集装箱9邻近所述船艏2的上建10。具体地，上建10靠近船艉3一侧的主甲板上设置有集装箱基座，并且在基座附近布置了相应的电线插座及水管接口，可布置12个居住集装箱，需要时可以大幅增加船舶的载人能力。
所述主甲板上靠近所述船艏2、所述船艉3分别设置用于装载货物的模块5，对应模块5的安装位置，主甲板上设置有限位装置，避免模块滑动以影响极地甲板运输船的平衡。
本实施例的极地甲板运输船还包括加热管11，所述加热管11通过支架安装于所述主船体1的主甲板下方，具体地，所述加热管11呈迂曲状结构，以提高传热效率。
本实施例中，主甲板的外围可拆卸设置有栏杆，在装载模块5时，可以拆掉部分栏杆，便于模块运输车可以从极地甲板运输船的侧边或者船艉开始运输模块，以方便模块的运输。
本实施例的极地甲板运输船还包括机舱，机舱设置有机舱吊口，用于吊装 机舱内的设备等，机舱吊口设置在靠近船艏一侧的模块和居住集装箱之间，居住集装箱与吊机之间的舱壁处设置有粮食库的入口，上建靠近船艉一侧还设置有吊机，吊机的工作半径覆盖机舱吊口以及粮食库等。
本实施例中的上建为全封闭结构，可以提高船员的工作和生活的舒适性。
本实施例中，极地甲板运输船还包括两个推进螺旋桨、两个舵以及侧推等部分，推进螺旋桨、舵以及侧推的结构和安装方式均为现有技术，在此不再赘述。
本实施例的极地甲板运输船，具有以下优点：
1、抗冰能力较高；
2、载重能力较大；
3、可用于运输大型油气生产/处理模块；
4、可以全年来往于北极航线。
在本说明书的描述中，参考术语“一实施例”的描述意指结合该实施例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例中以合适的方式结合。
以上结合具体实施例描述了本发明的技术原理。这些描述只是为了解释本发明的原理，而不能以任何方式解释为对本发明保护范围的限制。基于此处的解释，本领域的技术人员不需要付出创造性的劳动即可联想到本发明的其它具体实施方式，这些方式都将落入本发明的保护范围之内。
