Description

无人飞行器
技术领域
本发明涉及一种带有喷洒装置的无人飞行器。
背景技术
近年来,随着多旋翼飞行器发展,因其具有机动灵活、反应快速、无人飞行、操作要求低等优点,引起了其在多个领域的应用,特别是在农业植保领域。多旋翼飞行器上的喷洒装置是影响其作业效率的重要部分之一。
相关技术中,喷洒装置的驱动轴与安装壳体之间存在密封性问题,液体很容易进入到安装壳体内部,导致喷洒装置内的驱动件短路和腐蚀,极大地降低了喷洒装置的可靠性和使用寿命。常规的密封圈并不足以起到完全密封的作用,例如O型密封圈,而且还会影响到转动件(例如驱动轴)的转动效率。
发明内容
本发明提供一种无人飞行器,旨在至少在一定程度上解决相关技术中的技术问题之一。
根据本发明实施例的一种无人飞行器,包括机体和设置于机体上的喷洒装置,喷洒装置包括:
喷洒盘,用于将液体喷出;
驱动装置,包括用于向所述喷洒盘提供动力的驱动件以及由所述驱动件驱动其转动的驱动轴,所述驱动轴与所述喷洒盘固定连接;
壳体件,包括用于固定安装并收纳所述驱动件的主壳体以及沿所述主壳体延伸至所述喷洒盘上的次壳体,所述主壳体设有收容所述驱动件的容置腔体,所述次壳体设有与所述容置腔体相通以用于供所述驱动轴插入的导通孔;
密封圈,包括防水挡圈,所述防水挡圈设有贯穿所述防水挡圈且用于插入转动轴的贯通孔,所述贯通孔的内壁为曲面,所述驱动轴穿过所述贯通孔,所述贯通孔的内壁紧贴所述驱动轴的外表面以及所述防水挡圈的外壁抵持于所述导通孔的孔壁上。
本发明的有益效果:通过将贯通孔的内壁设计为曲面,以使贯通孔与转动轴紧密接触,减少了所述密封圈与所述转动轴之间的摩擦,以利于所述转动轴的转动。
附图说明
图1是根据本发明实施例的无人飞行器的喷洒装置的结构示意图。
具体实施方式
下面详细描述本发明的实施例,所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。
参见图1所示,本发明的实施例的一种无人飞行器,包括机体和设置于机体上的喷洒装置,所述喷洒装置包括:
喷洒盘1,用于将液体喷出;
驱动装置,包括用于向所述喷洒盘提供动力的驱动件以及由所述驱动件驱动其转动的驱动轴2,所述驱动轴2与所述喷洒盘固定连接;
壳体件3,包括用于固定安装并收纳所述驱动件的主壳体以及沿所述主壳体延伸至所述喷洒盘上的次壳体,所述主壳体设有收容所述驱动件的容置腔体,所述次壳体设有与所述容置腔体相通以用于供所述驱动轴插入的导通孔;
密封圈4,包括防水挡圈,所述防水挡圈设有贯穿所述防水挡圈且用于插入转动轴的贯通孔,所述贯通孔的内壁为曲面,所述驱动轴穿过所述贯通孔,所述贯通孔的内壁紧贴所述驱动轴的外表面以及所述防水挡圈的外壁抵持于所述导通孔的孔壁上。
本发明的有益效果:通过将贯通孔的内壁设计为曲面,以使贯通孔与转动轴紧密接触,减少了所述密封圈与所述转动轴之间的摩擦,以利于所述转动轴的转动。该密封圈同心设置所述防水凸起以利用所述防水凸起起到径向和轴向固定的作用。
