在一些具有喷洒功能的可移动平台(例如植保无人机、喷洒车等)中，喷洒系统包括多个水箱，通过多个水箱盛放药液。随着上述可移动平台应用场景更加多元化，对于喷洒精度、药量控制的要求越来越高。以植保无人机为例，剩余药量检测、航线规划以及断药续航等功能已成为标配，这些功能的实现需要依靠对水箱中药量的精准测量。
在相关技术中，通常在每个水箱上都设置一个液位计进行药量测量。由于液位计的成本和重量较高，上述方式会导致整机的成本和重量的增加。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请实施例的附图，对本申请的技术方案进行清楚、完整地描述。显然，所描述的实施例是本申请的一个实施例，而不是全部的实施例。基于所描述的本申请的实施例，本领域普通技术人员在无 需创造性劳动的前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，除非另外定义，本申请使用的技术术语或者科学术语应当为本申请所属领域内具有一般技能的人士所理解的通常意义。若全文中涉及“第一”、“第二”等描述，则该“第一”、“第二”等描述仅用于区别类似的对象，而不能理解为指示或暗示其相对重要性、先后次序或者隐含指明所指示的技术特征的数量，应该理解为“第一”、“第二”等描述的数据在适当情况下可以互换。若全文中出现“和/或”，其含义为包括三个并列方案，以“A和/或B”为例，包括A方案，或B方案，或A和B同时满足的方案。此外，为了便于描述，在这里可以使用空间相对术语，如“上方”、“下方”、“顶部”、“底部”等，仅用来描述如图中所示的一个器件或特征与其他器件或特征的空间位置关系，应当理解为也包含除了图中所示的方位之外的在使用或操作中的不同方位。
本申请实施例提供了一种喷洒组件，该喷洒组件可以应用于各种需要实现喷洒功能的设备中，例如，植保无人机、喷洒车或人力喷洒装置等。下面将以喷洒组件应用于植保无人机为例进行详细说明。
图1示出了本申请一个实施例可移动平台的结构示意图，其中，可移动平台为植保无人机，该可移动平台包括喷洒组件。图2示出了图1的可移动平台的俯视示意图。图3示出了图1的可移动平台的仰视示意图。图4示出了图1的可移动平台的侧视示意图。图5示出了图1的可移动平台的另一个角度的侧视示意图。
如图1至图5所示，喷洒组件包括多个储液箱10和液位检测装置20。多个储液箱10的底部相互连通以形成连通器，多个储液箱10中的至少两个具有安装部。液位检测装置20选择性地与至少两个安装部中的一个可拆卸连接，以检测该安装部对应的储液箱10内的液位。
其中，“连通器”指的是底部彼此连通的至少两个容器构成的整体结构，这些容器的顶部开口或者相互连通以使各容器内液面以上的气体压强相同，同一种液体不流动时在连通器内的液面始终保持在同一水平面上。
由于多个储液箱10的底部相互连通形成连通器，多个储液箱10内的液面始终平齐，只需通过液位检测装置20检测一个储液箱10内的液位，通过测得的液位数值能够计算得出多个储液箱10内当前液体的总量(液位数值乘以多个储液箱10的横截面积)。上述方式只需设置一个液位检测装置20即可实现多个储液箱10内液体液位/液量的测量，有利于降低成本和重量。
此外，多个储液箱10中的至少两个具有安装部，安装部均可以用于安装液位检测装置20。液位检测装置20为可拆卸式结构，一方面便于液位检测装置20进行清洗、维修、更换等操作；另一方面可在上述至少两个储液箱10的安装部之间进行选择性装配，使用更加灵活，若当前安装液位检测装置20的储液箱10发生损坏等无法再进行正常使用或测量液位的情况，也可以将液位检测装置20拆装到其他具有安装部的储液箱10上使用。
需要说明的是，依据上述连通器原理可知，需要在多个储液箱10的顶部设置与大气连通的开口或者将多个储液箱10的顶部相互连通，从而保证多个储液箱10内液面以上的区域的气体压强相同，进而使多个储液箱10内的液体液面平齐。
另外，在本实施例中，喷洒组件或配置有喷洒组件的整机设备还包括控制模块，液位检测装置20检测得到一个储液箱10内的液位并发出相应的液位信号传输给控制模块，再通过控制模块进行后续的计算、控制等处理。由于液位检测装置20设置为一个，发出的信号也只有一个，不存在多信号冲突或者融合的问题。
如图1至图5所示，在本申请一些实施例中，储液箱10的数量为两个，两个储液箱10均具有安装部。液位检测装置20可以安装在两个储液箱10中的任一个上。如果当前安装液位检测装置20的储液箱10发生无法再进行正常使用或测量液位的故障，可以将液位检测装置20拆装到另一个储液箱10上，从而保证液位检测装置20正常使用。
本领域技术人员可以理解地，储液箱10的数量不限于两个，在其他实施方式中，储液箱10的数量可以根据对喷洒组件总液量、单个储液箱10的体积等要求进行选择。例如，储液箱10的数量可以为三个、四个、五个等等。
需要说明的是，当储液箱10的数量为两个以上时，既可以仅在部分储液箱10(至少两个)上设置安装部，也可以在全部储液箱10上均设置安装部。若全部储液箱10上均设置安装部，液位检测装置20可以根据实际使用需要安装在任一个储液箱10上，灵活性更高。此外，如果当前安装液位检测装置20的储液箱10发生无法再进行正常使用或测量液位的故障，可以将液位检测装置20拆装到其他任一个储液箱10上，备用的能够安装液位检测装置20的储液箱10更多，从而有利于保证液位检测装置20的正常使用。
在本申请一些实施例中，液位检测装置20可以为多种能够测量液体液位的检测装置。例如，液位检测装置20包括但不限于霍尔式液位计、超声波液位计、射频导纳液 位计、雷达液位计、光电液位计中的一种。在本实施例中，液位检测装置20用于对储液箱10内的液位进行连续测量，实时监测储液箱10内的液位的变化。当然，在其他实施方式中，液位检测装置20也可以定时对储液箱10内的液位进行间断测量。
图6示出了本申请一个实施例的喷洒组件的液位检测装置20与储液箱10通过螺纹部21和螺母22连接的结构示意图。图7示出了本申请一个实施例的喷洒组件的液位检测装置20与储液箱10通过连接法兰23连接的结构示意图。
如图2、图6以及图7所示，在本申请一些实施例中，安装部包括安装口11，安装口11设置在储液箱10的顶部。液位检测装置20可拆卸地连接在安装口11处。液位检测装置20部分通过安装口11插入至储液箱10内。液位检测装置20从结构上可大致分为一体式和分体式两种，其中，有些一体式的液位检测装置20需要将探测部分插入至储液箱10的内部进行测量，例如，一体式超声波液位计、射频导纳液位计、雷达液位计、一体式光电液位计等等。因此，将安装部设置为包括位于储液箱10的顶部的安装口11，上述一体式的液位检测装置20通过安装口11能够插入至储液箱10内，以至少使该液位检测装置20的探测部分置于储液箱10的内部。
优选地，液位检测装置20与安装口11的侧壁螺纹连接。通过液位检测装置20与安装口11的侧壁之间的螺纹连接来实现液位检测装置20的可拆卸，结构简单，装配方便。当然，液位检测装置20在安装口11处的连接方式不限于此，在其他实施方式中，液位检测装置20也可以采用其他可拆卸连接方式。
例如，如图6所示，在本申请另一些实施例中，液位检测装置20具有螺纹部21，液位检测装置20的螺纹部21至少部分穿过安装口11后与配套的螺母22连接。当螺母22与螺纹部21拧紧后，液位检测装置20被固定到安装口11处。上述螺母22可以为图6中所示的独立于储液箱10的壁体的结构，此时装配螺母22和螺纹部21时则需要在储液箱10的内部进行操作。此外，上述螺母22也可以与储液箱10的壁体连接固定为一体，此时则直接在储液箱10的外部转动液位检测装置20进行连接即可。
再例如，如7图所示，在本申请另一些实施例中，液位检测装置20通过连接法兰23连接在安装口11处。具体地，液位检测装置20的侧壁上固定有连接法兰23，当液位检测装置20需要位于储液箱10内部的部分穿过安装口11后，将连接法兰23与储液箱10的壁体通过螺栓等紧固件进行连接。相比于前述两种螺纹连接的方式，通过连接法兰23连接的方式对安装口11的尺寸的要求相对较低，即使安装口11的尺寸大于液 位检测装置20对应位置的径向尺寸，只要在连接法兰23能够进行连接的范围内，即安装口11的尺寸小于连接法兰23的直径且可为螺栓等紧固件提供装配空间，就能够实现液位检测装置20在安装口11处的连接。
需要说明的是，液位检测装置20的安装方式不限于上述插入安装口11的方式，具体安装方式需要根据液位检测装置20的类型和工作原理进行选择。同样地，安装部的形式也不限于安装口11，在其他实施方式中，安装部的具体形式可以根据液位检测装置20的安装方式进行设计。
图8示出了本申请一个实施例的喷洒组件的液位检测装置20为外测式超声波液位计时和储液箱10、安装位12的结构示意图。图9示出了本申请一个实施例的喷洒组件的液位检测装置20为分体式光电液位计时和储液箱10、安装位12的结构示意图。图10示出了本申请一个实施例的喷洒组件的液位检测装置20为分体式霍尔液位计时和储液箱10、安装位12的结构示意图。
如图8所示，在本申请另一些实施例中，安装部包括安装位12，安装位12设置在储液箱10的外壁上，液位检测装置20可拆卸地连接在安装位12上。其中，安装位12为储液箱10的壁体上能够安装液位检测装置20的区域。有些类型的液位检测装置20设置在储液箱10的外侧也能够对储液箱10内的液体液位进行检测，例如外测式超声波液位计。因此，针对这些液位检测装置20则可以将安装部设置为包括位于储液箱10的外壁上的安装位12，上述液位检测装置20连接在安装位12上，无需在储液箱10上开设安装口，也无需将液位检测装置20置于储液箱10内，不会对储液箱10内液体的纯度、无菌度等产生影响，同样储液箱10内液体也不会对液位检测装置20发生腐蚀。
以液位检测装置20为外测式超声波液位计为例，如图8所示，外测式超声波液位计包括超声波传感器24，超声波传感器24可拆卸地连接在安装位12上，通过测量超声波在介质中的回波时间和校准传播速度可计算得到液面的高度。需要说明的是，图8仅为超声波传感器24与安装位12位置关系的示意图，在实际应用时，超声波传感器24和安装位12的数量、设置位置可以根据测量需要进行选择。例如，超声波传感器24可以为两个，一个超声波传感器24设置在储液箱10的侧面上，另一个超声波传感器24设置在储液箱10的底面上，安装位12的数量和设置位置与超声波传感器24相同。
当然，安装位12的设置位置也不限于在储液箱10的外壁上，在其他实施方式中，可以将安装位12设置在储液箱10的其他位置。
例如，如图9和图10所示，在本申请另一些实施例中，安装位12设置在储液箱10的内壁和外壁上。液位检测装置20为分体式结构。液位检测装置20的一部分连接在位于储液箱10内壁的安装位12上，液位检测装置20的另一部分连接在位于储液箱10外壁的安装位12上，液位检测装置20位于储液箱10内部和外部的两部分共同配合实现液位的测量。其中，液位检测装置20的上述两部分可以均与相应的安装位12可拆卸连接，也可以一部分与相应的安装位12可拆卸连接、一部分与相应的安装位12固定连接，此时若液位检测装置20需要拆装到备用的储液箱10上，只需对可拆卸的部分进行操作即可。分体式的液位检测装置20可以为多种，例如，分体式光电液位计、分体式霍尔液位计等。
如图9所示，以液位检测装置20为分体式光电液位计为例，分体式光电液位计包括反射光锥25和光电液位传感器26。反射光锥25连接在储液箱10的内壁上的安装位12上，光电液位传感器26连接在储液箱10的外壁上的安装位12上，反射光锥25和光电液位传感器26的位置对应。
由于分体式光电液位计的工作原理为在光电液位传感器26中设置一个发光二极管和一个接收器，根据发光二极管发出的光线在反射光锥25内的反射情况实现液位的测量。因此，至少需要将储液箱10的壁体对应于反射光锥25和光电液位传感器26的区域采用透光材料制成。当储液箱10内的液体浸没至少部分反射光锥25时，光线在反射光锥25内的反射情况由于光线在液体中的折射而发生改变，从而通过光电液位传感器26的接收器对光线的接收情况能够测得当前的液位。
需要注意的是，分体式光电液位计为接触式液位计，需要反射光锥25与液体接触才能够进行测量，其主要用于测量定点或小范围内的液位，无法进行实时连续液位测量。
如图10所示，以液位检测装置20为分体式霍尔液位计为例，分体式霍尔液位计包括浮球27、磁体28以及霍尔元件29。浮球27始终漂浮在储液箱10的液体液面上，磁体28与浮球27通过连接杆连接，连接杆位于磁体28和浮球27之间的一个位置作为固定支点，该固定支点连接在储液箱10的内壁上的安装位12上，霍尔元件29连接在储液箱10的外壁上的安装位12上，霍尔元件29的位置与磁体28的位置相对应。随着储液箱10的液体液位变化，浮球27也同样在高度上发生变化，从而带动磁体28动作，霍尔元件29感应到磁场的变化，从而实现对液位的连续测量。
图11示出了本申请一个实施例的喷洒组件的储液箱10、插拔结构40以及连通结构 30的装配前的结构示意图。
如图11所示，在本申请一些实施例中，喷洒组件还包括连通结构30和多个插拔结构40。连通结构30具有内腔31。多个插拔结构40连接在连通结构30上。各插拔结构40具有与内腔31连通的通道41。每个储液箱10对应于至少一个插拔结构40。当储液箱10装设于插拔结构40上时，通道41与储液箱10连通，从而使各个储液箱10与连通结构30的内腔31均连通，进而使多个储液箱10形成连通器。
将多个储液箱10与连通结构30设置为可拆卸连接，便于储液箱10的插拔，从而提高换液效率。通过上述多个插拔结构40实现当储液箱10装设于插拔结构40上时能够使储液箱10与连通结构30的内腔31连通。在本实施例中，每个储液箱10对应一个插拔结构40，当然在其他实施方式中，也可以将每个储液箱10对应于多个插拔结构40。
优选地，如图11所示，储液箱10的底壁上具有出液口部13，通道41内设有顶推件42。当储液箱10装设于插拔结构40上时，顶推件42顶推出液口部13，以使通道41与储液箱10连通。其中，储液箱10的出液口部13向下凸出，出液口部13在未受到顶推时处于密封状态，当出液口部13插入至通道41内且顶推件42顶推出液口部13时，出液口部13被顶破或者被顶住上移，从而使出液口部13处形成用于出液的开口，通过该开口将储液箱10与通道41连通。当然，储液箱10与插拔结构40的通道41连通的方式不限于此，在图中未示出的其他实施方式中，当储液箱10装设于插拔结构40上时，也可以通过其他方式使储液箱10与通道41连通。例如，在储液箱10的底壁上设置常开的出液口，在出液口处设置一阀门装置，当储液箱10与插拔结构40对接后，手动或电动控制该阀门装置打开，从而使储液箱10内的液体通过出液口流向插拔结构40的通道41。
需要说明的是，多个储液箱10的底部之间的连通方式不限于此，在其他实施方式中，多个储液箱10的底部之间也可以通过其他结构进行连通。例如，多个储液箱10的底部之间通过管路连通；如果多个储液箱10无需进行拆卸，也可以将多个储液箱10的底部直接制作为相互连通的形式。
本申请实施例还提供了一种可移动平台，该可移动平台包括但不限于植保无人机、喷洒车或人力喷洒装置。下面将以可移动平台为植保无人机为例进行详细说明。
如图1至图5所示，可移动平台包括可移动主体50和喷洒组件，喷洒组件安装在可移动主体50上，喷洒组件为上述的喷洒组件。在本实施例中，可移动平台为植保无 人机，可移动主体50为植保无人机的机身。可移动平台还包括连接在可移动主体50上的机臂60、连接在机臂60端部的动力组件70以及连接在可移动主体50上的支撑脚架80。随着可移动平台的移动，可移动主体50携带着喷洒组件沿移动路线移动并在预设区域进行喷洒作业。
在本申请一些实施例中，多个储液箱10可拆卸地设置在可移动主体50上，从而提高换液效率。由于目前对植保无人机等具有喷洒功能的可移动平台的液体容量要求越来越高，为了便于单个储液箱10的插拔和提放，可通过增加储液箱10的数量来增加液体总容量。因此，本实施例的可移动平台的喷洒组件采用了上述液位测量方式，即使储液箱10的数量增多，也只需设置一个液位检测装置20即可实现液位测量，有利于降低整机的成本和重量。
如图1至图5所示，在本申请一些实施例中，喷洒组件的连通结构30固定在可移动主体50上，这样可以使连通结构30与可移动主体50成为一整体结构，使结构更加紧凑。当然，可以理解地，在其他实施方式中，连通结构30也可以固定在可移动平台的其他部件上，例如固定连接在可移动平台的支撑脚架80上。
具体地，可移动主体50具有上下贯通的容置空间51，连通结构30位于容置空间51的下方，多个储液箱10安装于容置空间51内，并且各储液箱10装设于对应的插拔结构40上。当多个储液箱10由可移动主体50向下装配时，多个储液箱10插入至容置空间51内，与此同时，储液箱10的底部装设于插拔结构40上，插拔结构40的通道41与储液箱10连通，从而使各个储液箱10与连通结构30的内腔31均连通，进而使多个储液箱10形成连通器。
需要说明的是，可移动主体50的具体结构以及与多个储液箱10的位置关系不限于此，在其他实施方式中，可移动主体50也可以为其他能够装配多个储液箱10的结构，例如，可移动主体50的周向外壁上具有与多个储液箱10一一对应的装配结构，多个储液箱10挂设在多个装配结构上。
对于本申请的实施例，还需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合以得到新的实施例。
以上，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，本申请的保护范围应以权利要求的保护范围为准。
