本公开的实施例提供了一种加液装置，该加液装置包括移动部件和加液部件，其中，移动部件包括支架和连接于支架底部的滚轮，支架通过滚轮移动。加液部件包括加液箱，加液部件与支架连接，并且加液部件被配置为相对于支架转动，以使加液箱相对于支架平置或倾斜。
本公开实施例的加液装置例如可以用于给植保无人机的水箱添加药液。此外，本公开实施例的加液装置还可以用于给其他需要加液的设备添加药液，其他需要加液的设备例如可以是能够喷洒液体的移动机器人。
图1示意性示出了根据本公开实施例的加液装置100的侧视示意图。
图2示意性示出了根据本公开实施例的加液装置100的立体结构示意图。
如图1和图2所示，加液装置100可以包括移动部件和加液部件，其中，移动部件可以包括支架111和连接于支架111底部的滚轮112，支架111可以通过滚轮112移动。加液部件可以包括加液箱121，加液箱121具有壳体，壳体内部具有容纳空间，该容纳空间可以用于盛装液体。
根据本公开的实施例，加液部件与支架111连接，并且加液部件被配置为相对于支架111转动，以使加液箱121相对于支架111平置或倾斜。在图1所示的状态下，加液箱121相对于支架111平置，在加液箱121处于平置状态的情况下，加液箱121内的液体的液面不超过加液箱121的出液口，即，加液箱121内的液体不会从加液箱121的出液口溢出。
图3示意性示出了根据本公开实施例的加液箱处于倾斜状态的示意图。
如图3所示，加液部件可以相对于支架111向前侧倾斜，以使加液箱121内液体的液面超过加液箱121的出液口，使加液箱121内的液体从加液箱121的出液口溢出，注入至无人机200等需要加液的设备中。当加液完成后，可以将加液部件由倾斜状态恢复为平置状态。其中，加液箱121轴线m-m与支架111轴线n-n的夹角α可以用于表征加液箱121相对于支架111的倾斜角度。
根据本公开的实施例，加液部件可以仅包括加液箱121，在加液部件仅包括加液箱121的情况下，加液箱121的底部可以直接与支架111转动连接。
根据本公开的实施例，一方面利用结构简单的移动部件实现了加药箱的便捷移动，节省了人力和成本，并且移动部件简便轻巧，操作简单，便于携带和转运。另一方面，通过将加液部件转动连接于移动部件，使加液箱相对于移动部件的支架倾倒即可实现加液箱给其他设 备的注液操作，操作简便且省力，并且可以快速为无人机水箱加液，提高了作业效率。
如图1至图3所示，根据本公开的另一实施例，加液部件除了包括加液箱121以外，还可以包括容置筐122，加液箱121可拆卸地连接于容置筐122内。例如，容置筐122可以是由若干侧板和底板围成的筐形结构，加液箱121可以通过容置筐122的开口放入容置筐122中。加液箱121与容置筐122可拆卸地连接在一起，例如，可以在容置筐122和加液箱121上设置卡扣结构或者连接结构，使得当加液箱121放入容置筐122中时，可以利用卡扣结构或者连接结构将加液箱121稳固地放置于容置筐122中。并且，在需要使加液箱121脱离容置筐122时，可以释放卡扣结构或者拆除连接结构，以使加液箱121顺畅地脱离容置筐122。其中，卡扣结构例如可以是类似于安全带卡扣的结构，连接结构例如可以是螺钉、螺栓、螺纹孔等紧固结构。在本公开另一实施例中，容置筐122例如还可以是由若干横杆和若干竖杆组成的框架型结构。
容置筐122的底部可以与支架111枢转连接，以使容置筐122能够相对于支架111转动，进而使容置筐122中的加液箱121能够相对于支架111倾斜。
根据本公开的实施例，通过设置与支架转动连接的容置筐，并将加液箱可拆卸地放置于容置框中，一方面，可以使加液装置适用于不同规格的加药箱，可以根据实际需要将不同规格的加药箱连接于容置筐中。另一方面如果将加药箱直接连接在支架上，那么需要在每个加药箱底部均设置连接件，成本较高，如果采用容置筐，则可以仅在容置框底部设置连接件，因此可以节约成本。
如图2所示，根据本公开的实施例，支架111可以包括第一梁1111，第一梁1111例如可以是横梁，第一梁1111与支架111的高度方向相垂直。容置筐121包括第一侧边1221，第一侧边1221可以是容置筐121的一个底边，第一侧边1221上设置有连接件1222，连接件1222套接于第一梁1111，容置筐122被配置为绕第一梁1111转动。
例如，连接件1222可以是环形结构，第一侧边1221上可以并排设置若干个环形结构，第一梁1111可以穿设于该若干个环形结构中，环形结构与第一梁1111不可脱离并且环形结构能够绕第一梁1111转动。基于该连接结构，可以使容置筐121绕第一梁1111转动，进而使加液箱相对于支架转动。
根据本公开的实施例，支架111还可以包括第二梁(图中未示出)，第二梁与第一梁1111平行设置，并且第二梁与第一梁1111平齐，即，第二梁相对于支架底部的高度与第一梁1111相对于支架底部的高度可以基本相等。容置筐122还可以包括第二侧边(图中未示出)，第二侧边与第一侧边1221相对，第二侧边例如可以是与第一侧边1221相互平行且相对的一个底边。如图3所示，第二侧边上可以设置有与第二梁相匹配的卡接件1223，卡接件1223例如可以是半环形结构，第二侧边上可以并排设置若干个半环形结构，该半环形结构的内径可以稍小于第二梁的外径。在加液箱121相对于支架111平置的情况下，如图1所示，卡接件1223可以卡接于第二梁，以使容置筐122能够稳固地连接于支架111。当容置筐122需要转动时，如图3所示，在外力的作用下，半环形结构可以脱离第二梁，使容置筐122能够转动。
根据本公开的实施例，如图2和图3所示，加液箱121还可以包括出液口123和箱盖124，箱盖124例如可以设置于加液箱121的顶部，出液口123可以设置于加液箱121的侧面。其中，箱盖124可以覆盖加液箱121的加药口，当加液箱121需要补液时，可以将箱盖124打开，以使加药口暴露，从而可以将药液通过加药口注入加液箱121中。并且可以直接通过加药口在加药箱中搅拌药液，在搅拌完成后可以将箱盖124覆盖于加药口处，避免药液挥发和洒出。
如图2和图3所示，容置筐122还可以包括把手125，把手125可以设置于容置筐122上与出液口123相对的一侧。例如，出液口123可以设置于容置筐122的前侧，把手125可以设置于容置筐122的后侧。在需要将容置筐122倾斜时，用户可以抓紧把手并转动容置筐122， 使容置筐122向前侧倾斜。其中，本文中所说的前侧和后侧是相对于移动部件的行进方向而言的。
在本公开另一实施例中，在加液部件没有设置容置框而是仅包括加液箱的情况下，加液箱的底部可以直接与支架枢转连接，加液箱与支架的连接方式可以参照上述容置筐与支架的连接方式。支架可以包括第一梁，加液箱的第三侧边可以通过转动连接件连接于第一梁，加液箱被配置为绕第一梁转动。支架还包括第二梁，加液箱的第四侧边可以通过卡接件卡接于第二梁。
如图1至图3所示，根据本公开的实施例，滚轮112可以设置于支架111的底部并且位于支架111的行进方向的后侧，支架111底部的前侧可以设置支撑脚架113。在移动部件不需要移动时，可以将支撑脚架113支撑于地面上，进而阻止滚轮112滑动。在移动部件需要移动时，可以将支架111向后倾斜，支撑脚架113脱离地面，使滚轮112可以随意滚动，用户可以推动移动部件向前或向后移动。
在本公开另一实施例中，滚轮112可以设置于支架111的底部并且分布于支架111的行进方向的前侧和后侧。例如，支架111的前后两侧均可以设置滚轮112，在移动部件需要移动时，无需将支架111倾斜，可以在支架111放平的情况下推动支架111移动。此外，位于支架111的前侧和/或后侧的滚轮上可以设置有锁定件，锁定件被配置为在特定状态下阻止滚轮滚动。例如，锁定件例如可以是制动器，在加液装置移动至无人机附近的加液位置时，可以利用锁定件锁定滚轮，例如可以夹抱住滚轮使其在摩擦力的作用下不能滚动，在加液完成后，可以释放锁定件，以使加液装置移动至下一个加液位置。
根据本公开的实施例，加液部件可以在人力作用下相对于支架转动，在本公开另一实施例中，加液装置还可以包括驱动部件，驱动部件被配置为驱动加液部件相对于支架转动，使加液部件能够在驱动装置的作用下自动转动，进一步节省人力，实现加液自动化。
驱动部件例如可以包括电机，电机的壳体可以固定于支架，电机的输出轴与加液部件固定连接。例如，第一梁1111可以是电机的输出 轴，容置筐122的第一侧边1221可以与第一梁1111固定连接，在第一梁1111转动过程中，可以带动容置筐122和加液箱121一同转动。例如，在电机正向转动过程中，容置筐122和加液箱121的倾斜角度随之加大，加液箱持续输出液体，当加液装置输出的液体量达到预定需求时，可以控制电机反向转动，容置筐122和加液箱121的倾斜角度随之减小，加液箱121停止输出液体。
图4示意性示出了根据本公开另一实施例的驱动部件的示意图。
如图4所示，在本公开另一实施例中，驱动部件例如可以包括自动伸缩杆131，自动伸缩杆131的第一端与支架枢转连接，第二端与加液部件枢转连接，具体地，第二端可以与容置筐122枢转连接。自动伸缩杆131例如可以是电动推杆，可以在电机的作用下自动伸长或缩短，随着自动伸缩杆131的长度的变化，容置筐122和加液箱121的倾斜角度也会随之发生变化。例如，在自动伸缩杆131伸长过程中，容置筐122和加液箱121的倾斜角度随之加大，加液箱121持续输出液体，当加液装置输出的液体量达到预定需求时，可以控制自动伸缩杆131缩短长度，容置筐122和加液箱121的倾斜角度随之减小，加液箱121停止输出液体。
根据本公开的实施例，加液装置还可以包括流量控制装置，该流量控制装置被配置为控制加液箱121中的液体的输出量。
更进一步地，流量控制装置例如可以根据无人机水箱的剩余容量，确定需要输出的药液量，进而控制药液的输出量，当输出量达到预定需求时(例如达到无人机水箱的需求量)，可以控制加液箱停止输出药液，其中，无人机水箱的剩余容量可以由用户手动输入。
例如，流量控制装置可以包括流量计和阀门，流量计和阀门可以均设于加液箱的出液口处。其中，流量计被配置为检测加液箱的出液口输出的液体的量，阀门被配置为打开或关闭加液箱的出液口。流量控制装置还可以包括控制器，控制器可以获取流量计的数据以及控制阀门的开闭，当从流量计获取的液体输出量达到预定需求时，可以控制阀门关闭，停止输出药液。
根据本公开的实施例，通过设置流量控制装置，能够实现液体输出量的控制，可以实时监测液体的输出量，并在输出量达到预定要求时停止输出药液，实现液体输出量的监测和自动控制。进一步地，还可以根据无人机水箱的剩余容量控制液体的输出量，使加液操作更为智能，加液效率更高。
在本公开另一实施例中，流量控制装置例如可以类似于加油站使用的加油枪，在感应到无人机水箱中的药液加满时可以自动停止输出药液。
根据本公开的实施例，支架还可以包括支撑件，支撑件与第一梁连接，第一梁被配置为相对于支撑件沿支架的高度方向移动，以改变第一梁的高度。
如图2所示，支撑件例如可以包括分别连接于第一梁1111两侧的两个纵梁1112，第一梁1111能够沿两侧的纵梁1112上下移动，以将第一梁1111调整至合适的高度。例如，两个纵梁1112上可以设置滑轨，第一梁1111的两侧可以设置滑块，第一梁1111可以在滑轨和滑块的配合作用下上下移动并且能够锁定在一定高度位置处，例如可以通过销钉将第一梁1111的位置锁定。再例如，可以在纵梁1112上沿高度方向设置多个安装孔，当需要调节第一梁1111的高度时，可以将第一梁1111从原安装孔处拆下并安装至合适高度的安装孔处。此外，在第一梁1111的高度发生变化时，可以相应地调节第二梁的高度。
根据本公开的实施例，可以将第一梁设置为可升降的结构，以使加药箱的高度与无人机的高度相匹配，进而使加药箱的出液口与无人机的水箱进口更易对准。例如，当无人机高度较低时，可以将第一梁下调至合适的高度，加药箱也会相应的下降一定高度，使加药箱的高度与无人机的高度相匹配，加药箱倾倒时能够与无人机的水箱口对准。
本领域技术人员可以理解，本公开的各个实施例和/或权利要求中记载的特征可以进行多种组合和/或结合，即使这样的组合或结合没有明确记载于本公开中。特别地，在不脱离本公开精神和教导的情况下，本公开的各个实施例和/或权利要求中记载的特征可以进行多种组合和/或结 合。所有这些组合和/或结合均落入本公开的范围。
以上对本公开的实施例进行了描述。但是，这些实施例仅仅是为了说明的目的，而并非为了限制本公开的范围。尽管在以上分别描述了各实施例，但是这并不意味着各个实施例中的措施不能有利地结合使用。本公开的范围由所附权利要求及其等同物限定。不脱离本公开的范围，本领域技术人员可以做出多种替代和修改，这些替代和修改都应落在本公开的范围之内。
