Abstract

一种前置分水推进器，为提供一种在船首用动力分水原理减少阻力和提高推力提出本发明，它由进水管道，左侧扁形喷水口，右侧扁形喷水口和连接螺母组成外罩；推进器和推进器轴组成中间部分；外罩和中间部分都是可以独立更换的部分。

Description

前置分水推进器
技术领域
本发明涉及一种安装在船首的分水推进器。
背景技术
目前现有船用推进器技术中，没有安装在船首利用分水原理减少船的前进阻力和加大推力的动力装置。水的密度比空气大800多倍，船航行时受水的摩擦力随着船速的加快船的正面阻力不断加大。当大，中型船的速度达到10海里时，大，中型船的正面阻力的80％以上在船的首部。因此只改变船的外形，加大推力都不能使船的前进速度有明显的提高。
发明内容
本发明由推进水管，左侧扁形喷水口，右侧扁形喷水口，推进器，推进器轴和连接螺母组成。推进器将水从船的正前方吸入进水管道，由左侧扁形喷水口和右侧扁形喷水口向船的侧后方喷出高速水流，这种向侧后方喷出的高速水流可以推动船向前行驶。随着船速的加快船正前方的阻力在加大，这时本发明的左侧扁形喷水口和右侧扁形喷水口向船侧后方喷出的高速水流，可以在船的正前方形成分水力量来减少船的前进阻力。实验证明船首分水推进器在不增加船动力的情况下，可以减少船一倍以上的前进阻力，而且左侧扁形喷水口和右侧扁形喷水口向船的侧后方喷出的高速水流形成扰流减少了诱导引流造成的无效作功。
本发明结构简单，可以保证与船体连接时不需要改变船的现有结构。本发明与现有技术相比，填补了现有船用推进器技术中没有船首分水器的空白。船首分水推进器能有效的减少船的前进阻力，起到节省能源，保护环境和提高效率的作用。
附图说明
附图为本发明结构示意剖视图，其中1＝进水管道，2＝左侧扁形喷水口，3＝右侧扁形喷水口，4＝推进器，5＝推进器轴，6＝连接螺母。
请参考图，本发明是由进水管道1，左侧扁形喷水口2，右侧扁形喷水口3，连接螺母6组成本发明的外罩，推进器4和推进器轴5组成中间部分，连接螺母6可将本发明同船首连接起来。
本发明推进水管道1中的水流速度高于船速时开始起到推进作用，进水管道1中的水流速度与分水推进功效成正比。

Claims (5)

1、前置分水推进器，由一个流体导管和一个推进器并推进器驱动轴组成；流体导管包括一个入水口通道和安装在入水口通道两侧的第一、第二扁平出口喷嘴通道，所述入水口通道朝向前方，每个出口喷嘴通道朝向船体的侧后方；在入水口安装有一个推进器，并有推进器驱动轴，将所述前置分水推进器设置在水下的船体首部，出口端沿船体相反的两侧指向船尾，这样水从入口被导入，然后由推进器加压力从船体的两侧从出口喷出。
2、根据权利要求1所述的前置分水推进器，其中两个出口喷嘴通道的截面面积之和与入水口通道的截面的面积相同。
3、根据权利要求1或2所述的前置分水推进器，其中在流体导管的使用过程中，所述流体导管可以独立于推进器和驱动轴被替换。
4、根据权利要求1或2所述的前置分水推进器，其中在推进器和驱动轴的使用过程中，所述推进器和驱动轴可以独立于流体导管被替换。
5、根据权利要求3所述的前置分水推进器，其中在推进器和驱动轴的使用过程中，所述推进器和驱动轴可以独立于流体导管被替换。
