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。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
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。
本申请实施例首先提供一种喷洒组件，参见图1-图3，喷洒组件用于盛装农林植保过程中需要的液体并对其进行喷洒，喷洒组件可以单独使用，或者，参见图2，喷洒组件可以安装于无人车、无人机等可移动平台，也可以安装于人工驾驶的车、飞机、船等，以组成农业植保器械进行使用。
如图1中示出的，喷洒组件包括：多个储液箱11、连通部12和安装部13。
储液箱11用于盛放液体，例如化学药剂、水等。为了满足农林植保需求，期望喷洒组件能够具有更大的容量，然而大容量的药箱并不便于安装，尤其是当储液箱11设置成可拆卸时，可能需要多人配合才能够完成安装和拆卸，为此，根据本申请实施例的喷洒组件设置了多个储液箱11。
储液箱11形成有盛放液体的内腔，在一些实施例中，优选地，储液箱11的内腔具有固定的横截面积，从而方便根据储液箱11中的液面高度计算储液箱11中的液体量，在一些实施例中，储液箱11的内腔在不同高度处的截面积可以不同。在一些实施例中，多个储液箱11的内腔的横截面积可以相同，也可以不同。在一些实施例中，优选地，多个储液箱11的内腔具有相同的高度，以避免多个储液箱11中的液面高度出现差异，例如部分储液箱11中的液面高度超过了其他储液箱11中液面的最大高度。
在一些实施例中，多个储液箱11可以具有完全相同的结构和尺寸。在一些实施例中，多个储液箱11的结构和尺寸可以不完全相同，例如，部分储液箱11可以具有较大的截面积而另一部分储液箱可以具有较小的截面积，又例如，部分储液箱11可以呈圆柱状而另一部分储液箱可以呈立方体状，本领域技术人员可以灵活地配置多个储液箱11，从而当喷洒组件被安装在农业植保器械，例如农业无人机、无人车时，能够充分利用这些农业植保器械的安装空间。
在一些实施例中，仍然参照图1，储液箱11的顶部可以设置有把手，从而方便用户进行储液箱11的安装和/或拆卸。
在一些相关技术中，当设置有多个储液箱时，通常会在每个储液箱中设置一个液位计，而储液箱又通常设置成可拆卸式以方便装药，使得液位计与喷洒组件和/或安装有喷洒组件的农业植保器械之间没有稳定的连接，只能够采用独立的电源，例如纽扣电池进行供电，需要频繁的更换电池。并且，只能够使用无线传输的方式与农业植保器械的控制模块(例如，一个或多个处理器)通信，进一步影响了液位计的续航时间，并且，多个液位计同时与控制模块进行通信时彼此之间可能产生干扰，造成信号冲突或融合，进而导致测量结果并不准确。
在又一些相关技术中，采用非接触式液位计进行液位的测量，这些非接触式液位计，例如霍尔传感液位计，这些非接触式液位计能够设置在储液箱外部，例如固定于喷洒组件中的其他部件和/或固定于农业植保器械的机身，然而，仍需使用多个液位计才能够完成多个储液箱中液位的测量，而多个液位计的固定对喷洒组件和/或农业植保器械中各部件的空间布局提出较大的挑战，并且，难以保证液位计使用过程中的安全性。同时，由于安装位置受到限制，这些液位计量程通常难以完全覆盖储液箱中液面的高度范围。
为了至少部分地解决上述相关技术中的问题，本申请实施例的喷洒组件还包括连通部12和安装部13，连通部12用于将多个储液箱11连通，并且，安装部13与连通部12连通，从而，安装部13与多个储液箱11之间构成连通器结构，此时，根据连通器原理，安装部13与多个储液箱11中的液面高度将会相同。在一些实施例中，例如图1中示出的，储液箱11的底壁可以设置有与连通部12连通的开口，即，连通部12设置成将多个储液箱11的底部连通，从而，只要储液箱11中存在液体，安装部13中就能够存在相同高度的液体。在一些使用场景中，储液箱11中的液体可能会存在沉淀(例如某些农药未完全溶解时产生的沉淀)，在将储液箱11的底部连通时，在一些其他的实施例中，储液箱11与连通部12进行连通的开口也可以设置在储 液箱11的侧壁上靠近底部的位置，即，连通部12可以将储液箱11的中部靠近底部的位置连通，
安装部13用于安装液位计14，液位计14测量得到的安装部13内的液面高度即为多个储液箱11中的液面高度。可以理解地，为了实现安装部13与多个储液箱11中的液面高度相同，需要安装部13的内腔高度等于或略大于多个储液箱11的内腔高度，使得安装部13中的液面高度范围能够不小于储液箱11中的液面高度范围。
在一些实施例中，安装部13可以设置成管状或柱状，此时安装部13中各个高度处的截面积相同。在一些实施例中，安装部13也可以设置成其他形状，以适应不同种类的液位计14。在一些实施例中，液位计14可以是非接触式液位计，安装部13可以包括一个与连通部12连通的管状件以及设置在管状件外侧的固定结构，并将液位计14安装该固定结构上。
在这样的实施例中，只需要使用一个液位计14就能够完成多个储液箱11中的液面高度的测量，节约了成本，同时，液位计14的信号只有一个，不会产生多信号的冲突问题，使得测量结果更加准确。
进一步，在这样的实施例中，通过设置安装部13为液位计14提供了安装空间，使得液位计14可以无需与储液箱11一同进行频繁的拆卸，从而，液位计14能够通过线材与喷洒组件或农业植保器械的电源、控制组件等进行连接，供电和通信更加方便。同时，安装部13为液位计14的安装提供了充足的空间，使得液位计14设置的位置不再受到喷洒组件的其他部件或农业植保器械的机身的限制，量程能够覆盖储液箱11中的液面高度范围，从而能够对储液箱11中的液面高度进行相对连续的测量。
在一些实施例中，多个储液箱11可以环绕安装部13设置，例如图1-3中示出的喷洒组件中，两个储液箱11分别设置于安装部13的两侧，从而在使用过程中，安装部13位于多个储液箱11的内侧，避免液位计14受到损坏。在未示出的实施例中喷洒组件还可以具有3个、4个甚至更多个储液箱11，这些储液箱11可以均匀地环绕安装 部13设置，也可以不均匀地环绕安装部13设置，只需使安装部13尽可能少的暴露于喷洒组件的外部即可。
在一些实施例中，参照图2和图3，安装部13通过第一接口121与连通部12连通，多个储液箱11分别通过对应的第二接口122与连通部12连通。第一接口121和第二接口122可以是连接阀、连接法兰等用于管路连接的结构，例如，第一接口121可以包括设置在安装部13上的第一法兰和设置在连通部12上的第二法兰，通过两个法兰的对接将安装部13和连通部12连通，在一些其他的实施方式中，本领域技术人员还可以选择其他合适的方式来设置第一接口121和第二接口122。
在一些实施例中，第一接口121和第二接口122可以具有相同的结构和尺寸，在一些实施例中，第一接口121和第二接口122的结构和尺寸可以不完全相同。在一些实施例中，多个第二接口122的尺寸可以相同，也可以不同，例如部分储液箱11对应的第二接口122具有较大的截面积，而另一部分储液箱11对应的第二接口具有较小的截面积。在一些实施例中，安装部13可以不经由第一接口121而直接与连通部12一体成型或焊接设置。在一些实施例中，至少部分储液箱11也可以不经由第二接口122而直接与连通部12一体成型或焊接设置，但这可能导致该部分储液箱11无法进行拔插操作。
在一些实施例中，第二接口122可以设置成快拆式接口，例如，第二接口122可以包括设置在储液箱11的开口处第一配合件和设置在连通部12上对应的开口处第二配合件，第一配合件和第二配合件可以通过凸起-凹槽配合、过盈配合、旋转后过盈配合等结构实现配合连接和快速拆装，本领域技术人员可以根据实际情况选择合适的连接结构进行连接。在一些实施例中，储液箱11可能需要在装满液体的情况下进行安装，此时，第二接口122可以包括设置在储液箱11的开口处的单向阀以及设置在连通部12上对应的开口处的连接管，单向阀可以在储液箱11未安装至连通部12时处于关闭状态，避免储液箱11中的液体流出，连接管可以凸出设置在连通部12上，从而， 在安装储液箱11时，单向阀将会在连接管的压力作用下开启，使得储液箱11与连通部12连通。
在一些实施例中，与第二接口类似的，第一接口121也可以设置成快拆式接口，在此不再赘述。
在一些实施例中，尽管安装部13和多个储液箱11之间形成了连通器，能够保证静止状态下安装部13和多个储液箱11中的液面高度相同，然而测试发现，在将储液箱11中的液体泵送喷洒时，开始泵送的瞬间安装部13中的液面高度将会低于储液箱11中的液面高度，并且，此时安装部13中的液面高度与储液箱11中的液面高度之间的差值与泵送的流量呈正相关，而在泵送结束的瞬间，安装部13内的液面高度又将会突然脉动，此时安装部13内的液面高度大于储液箱11中的液面高度。这将导致泵送开始和结束时，或者泵送的流量发生改变时，安装部13中的液面高度难以反映多个储液箱11中液面的真实高度，进而导致测量结果的不准确。
为了解决上述问题，在一些实施例中，进一步的将安装部13的截面积与所述第一接口121的截面积的比值设置成与每个所述储液箱11的截面积与对应的所述第二接口122的截面积的比值相同。
具体地，参照图3，储液箱11的截面积S1可以是指储液箱11的内腔的横截面积，即，储液箱11中盛放的液体的横截面积，与储液箱11对应的第二接口122的截面积S2可以是指第二接口122的内截面积，即，流经该第二接口122处的液体的截面积。需要注意的是，在这样的实施例中，可能需要保证储液箱11内腔的各个高度处具有基本相同的截面积，由此才能够准确获取到储液箱11的截面积。
安装部13的截面积S3可以是指安装部13的内腔的横截面积，即，安装部13内的水流的截面积，而第一接口121的截面积S4是指第一接口121的内截面积，即，流经第一接口121的液体的截面积。在本实施中，将这些截面积的比值设置成S1/S2＝S3/S4，经过实验验证，这样的设置方式下，即使在泵送开始和结束时也能够保证安装部13内的液面高度与储液箱11中的液面高度相同，由此，能够对储液箱11内的液面高度进行更加准确地测量。
尽管图3中示出的两个储液箱11具有相同的截面积S1，然而在一些实施例中，不同的储液箱11具有不同的截面积，例如一些储液箱11的截面积可以为S5，此时，该储液箱11对应的第二接口122的截面积可以为S6，此时，可以使S1/S2＝S3/S4＝S5/S6。
进一步的，根据连通器原理，如果连通器的液面上方压力不相同，则也会导致连通器中的液面高度不相同，为此，在一些实施例中，可以在多个储液箱11以及安装部13的顶部设置排气孔，以使得储液箱11与安装部13中的液面上方的压力均保持为大气压，从而安装部13以及多个储液箱11中的液面高度能够始终相同，并且，这样的实施例中排气孔还可以减少储液箱11中的液体被泵送时受到的阻力。优选地，可以在每个储液箱11以及安装部13的顶部设置多个排气孔，而每个排气孔设置成具有较小的直径，以避免外界环境中的杂质通过排气孔进入储液箱11以及安装部13中。
在一些实施例中，作为替代地，参见图3，喷洒组件可以设置有排气管15，排气管15可以将多个储液箱11的顶部与安装部13的顶部连通，以使得储液箱11与安装部13中的液面上方的压力相同，在一些实施例中，排气管15可以设置有排气孔，使得储液箱11与安装部13的液面上方的压力保持在大气压，减少储液箱11中的液体被泵送时受到的阻力，并且，排气孔设置在排气管15上能够尽可能地减少外界杂质进入储液箱11和安装部13。优选地，排气管15可以与储液箱11以及安装部13的顶壁连接，以避免储液箱11中的液体进入排气管15。
在上文所描述的实施例中，一个或多个技术问题的解决并不依赖于特定类型的液位计14，在这些实施例中，喷洒组件的液位计14可以不与储液箱11、连通部12和安装部13一同向用户提供，用户可以自行搭配合适的液位计14并将其安装至安装部13进行使用，液位计14可以是接触式液位计或者非接触式液位计。在一些实施例中，安装部13内或者安装部13外侧可以配置有多种类型的接口以便适应多种类型的液位计14，这些接口可以包括机械接口，即，用于固定 液位计14的接口，还可以包括电接口，电接口可以用于液位计14的供电、通信等。在一些实施例中，喷洒组件可以包括上述液位计14。
在一些实施例中，仍参照图1，液位计14可以包括浮标件141和感测件142，浮标件141可以设置在安装部13内，并配置成随安装部13内的液面高度变化而移动，感测件142可以感测浮标件141的位置以获取安装部13内的液面高度。可以根据感测件142的类型来选择合适的浮标件141，例如，感测件142可以被配置成通过磁场感应、电场感应、光学感应等来感测浮标件141的位置，相应地，浮标件141可以由磁性材料、反光材料等制成，以配合感测件142实现其功能。
在一些实施例中，仍然参照图1，喷洒组件可以包括固定部16，固定部16用于将感测件142固定在安装部13，固定部16可以根据所使用的感测件142的具体类型来设置，例如，当感测件142需要隔绝液体进行使用时，固定部16可以呈管状并设置在安装部13内，感测件142可以设置在固定部16的管腔内，从而，固定部16在为感测件142提供固定的同时还能够将感测件142与安装部13内的液体隔离，以避免感测件142被损坏，当感测件142使用光学感应来感测浮标件141的位置时，固定部16还可以进一步的由透光材料制成。在一些实施例中，固定部16也可以设置在安装部13的外侧，以将感测件142设置在安装部13的外壁上。在一些实施例中，固定部16可以与安装部13可拆卸地连接，当需要更换感测件142时，可以将固定部16拆除并进行更换。
在一些实施例中，固定部16可以与连通部12的底部连接，从而，感测件142可以借助固定部16延伸至连通部12中，使得感测件142可感测的范围能够覆盖整个安装部13。同样地，固定部16可以配置成与连通部12的底部可拆卸地连接，以方便感测件142的更换。
在一些实施例中，感测件142可以包括多个霍尔传感器，多个霍尔传感器可以沿着固定部16的轴向分布，从而，多个霍尔传感器可以使得感测件142的感测范围覆盖整个安装部13。
在一些实施例中，参照图4-图6，喷洒组件还可以包括泵17、输送部18和喷头19，泵17可以将储液箱11中的液体经由输送部18泵送至喷头19进行喷洒。泵17可以是例如液压泵、隔膜泵等，输送部18可以是刚性管路，也可以是柔性管路。本领域技术人员可以根据实际情况进行设置，在此不再赘述。
在图4-图6示出的实施例中，泵17、输送部18、喷头19被设置在农业植保器械的机身上，然而可以理解地，当喷洒组件单独使用时，泵17、输送部18和喷头19可以根据实际情况被设置在合适的位置，例如，泵17可以被设置在连通部12上，或者被固定于喷洒组件的其他部件，输送部18可以被配置成柔性管路，喷头19可以被设置在输送部18的自由端，从而，用户可以手持输送部18和喷头19完成喷洒动作。
在一些实施例中，输送部18可以和连通部12连通，即，储液箱11中的液体依次流经连通部12和输送部18而后被喷洒。这样的实施例中，实际上多个储液箱11中的液体基本被同时泵送，进一步避免了泵送时各个储液箱11中的液面高度不同或安装部13与储液箱11中的液面高度不同的情况发生。在一些实施例中，可以设置多个输送部18，多个输送部18可以分别连接在连通部12不同方向上的侧壁，每个输送部18又可以配置有一个或多个喷头19，从而能够同时在多个方向上进行喷洒。
在一些实施例中，输送部18也可以和多个储液箱11连通，例如，每个储液箱11可以与一个输送部18连通，或者，至少部分储液箱11可以与输送部18连通，然而在这样的实施例中，由于液体直接从每个储液箱11中被抽取，从而，部分储液箱11中的液面下降可能相对较快，导致多个储液箱11中的液面高度在泵送过程中无法始终保持相同，进而导致安装部13中的液面高度无法反映储液箱11中液面的真实高度。为此，在一些实施例中，可以在每个储液箱11上设置一个输送部18，并以基本相同的流量来对每个储液箱11中的液体进行泵送，以尽可能减少储液箱11中的液体抽取速度的差异。在一些实施例中，还可以进一步地将安装部13的截面积与第一接口121的 截面积的比值，设置成与每个储液箱11的截面积与输送部18在储液箱11上的接口处的截面积的比值相同，以进一步保证泵送开始和结束的瞬间多个储液箱11与安装部13中的液面高度相同。
根据本申请的实施例还提供一种农业植保器械，参照图2、图4-图8，农业植保器械包括本体20，和设置在本体20上的喷洒组件10，喷洒组件10可以是上文所描述的任一实施例中的喷洒组件10。如上文所描述的，农业植保器械可以是配置有喷洒组件无人机、无人车、无人船，或者人工驾驶的车、飞机、船等，尽管下文以农业植保无人机为例对农业植保器械的一些技术细节进行描述，然而本领域技术人员可以理解地，以下的一个或多个实施例也可以作为农业植保车、农业植保船来实现。
在一些实施例中，参照图2，农业植保器械的本体20可以形成有容置空间21，连通部12可以固定在该容置空间21中，此时，安装部13内的液位计14可以经由连通部12与农业植保器械的其他部件进行连接，例如与农业植保器械的电源、控制模块等进行连接，以完成供电和通信。
在一些实施例中，参照图2和图4，本体20可以包括顶板22、侧板23和底板24，其中，侧板23连接顶板22和底板24，侧板23和底板24限定出容置空间21，这样的实施例中底板24和侧板23可以提供支撑和保护作用，并且可以进一步的将农业植保器械的电源、控制组件等设置在顶板22，使得本体20的结构布局更加合理。在一些实施例中，也可以是本体20的顶面凹陷形成容置空间21，在这样的实施例中，本体20的内部可以形成有第二容置空间，用于安装农业植保器械的电源、控制组件等。
在一些实施例中，本体20可以不形成容置空间，而在本体20的底部连接框架，将连通部12安装在该框架上。
在一些实施例中，参照图7，本体20可以包括两个侧板23，两个侧板23与底板24相对的两端连接。即，仅在底板24的两个侧面上设置侧板23与顶板22连接，而另外两个侧面上不设置侧板23，由此，可以减轻本体20的整体重量，在农业植保器械总体重量不变 的情况下能够设置更大容量的储液箱11。在一些实施例中，侧板23和底板24的宽度可以小于顶板22的侧边的长度，进一步的减轻本体20的重量。
在一些实施例中，连通部12可以设置在底板24上，例如，连通部12可以与底板24固定连接。在一些实施例中，如上文所描述的，安装部13可以配置有电性接口，或者液位计14可以通过线材与农业植保器械的电源、控制模块等电连接，此时，安装部13的电性接口或液位计14的线材可以经由底板24进行走线，而后连接至本体20上的电源、控制模块等。
在一些实施例中，储液箱11可以至少部分地收容在容置空间21中，此时，除了连通部12外，侧板23和底板24也能够为储液箱11提供一定的支撑和保护，以在农业植保器械运动过程中保持储液箱11的稳定性。
在一些实施例中，参照图2和图5，顶板22的中部镂空形成容置空间21的顶部开口，从而，储液箱11能够经由该顶部开口安装至容置空间21内的连通部12上，方便用户进行储液箱11的安装和拆卸，在一些实施例中，顶板22的中部可以设置有可开合的开口，当需要进行储液箱11的安装和拆卸时，可以将该开口打开以进行操作。在一些实施例中，储液箱11也可以经由容置空间21侧方的开口(例如上文所描述的实施例中未设置侧板23的两侧)来进行安装和拆卸。
在一些实施例中，如上文所描述的，喷洒组件还包括泵17、输送部18和喷头19，泵17将储液箱11中的液体经由输送部18泵送至喷头19进行喷洒。在一些实施例中，输送部18可以与连通部12连通。在一些实施例中，输送部18可以分别与每个储液箱11连通，具体的实现方式参见上文相关部分的描述，在此不再赘述。
在一些实施例中，参照图6，输送部18可以至少部分地延伸在侧板23面向容置空间21的一侧，从而，侧板23还可以为输送部供一定的保护作用，避免使用过程中输送部18受损出现漏液等情况。尽管在图6中仅描绘了一个输送部，然而本领域人员还可以在连通部12的另一侧也设置一个输送部18沿对应的侧板23进行延伸。
在一些实施例中，参照图6和图8，泵17可以设置在侧板23背离容置空间21的一侧，并与顶板22连接。可以理解地，将泵17设置在容置空间外可以避免储液箱11在安装和拆卸的过程中与泵17发生碰撞进而导致泵17的损坏。在这样的实施例中，输送部18可以在靠近泵17的位置穿过侧板23并与泵17连接。同样地，还可以在其他方向上设置泵17。
在一些实施例中，当农业植保器械为农业植保无人机时，本体20还可以包括脚架25，参见图7，脚架25可以与顶板22连接并向底板24所在的方向延伸，此时，脚架25的底端应低于底板24所在的位置，以避免着陆时底板24与着陆面发生碰撞。在一些实施例中，脚架25也可以设置在底板24上，此时可能需要底板24具有较大的宽度来固定脚架25。
在一些实施例中，参照图8，泵17可以连接在输送部18的一端，喷头19可以直接与泵17连接。
在一些实施例中，泵17也可以设置在输送部18的中部，而喷头19可以设置在输送部18的一端，即，喷头19可以不与泵17设置在一处，例如图8中示出的，当农业植保器械为农业植保无人机时，本体20可以包括机臂26和桨叶27，输送部18可以进一步沿着机臂26延伸至桨叶27处，喷头19可以设置在桨叶27下方，从而，当农业植保无人机飞行时，其产生的向下气流能够有助于喷头19喷洒出的液体的扩散。
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。
