Description

一种农用无人直升机的 U型药箱
技术领域
[0001] 本发明属于飞行器制造领域， 在 IPC分类中属于 B64大类， 具体涉及一种用于农 林植物保护 （植保） 作业的工业级电动无人直升机喷洒农药用的 U型药箱。 背景技术
[0002] 随着无人直升机在各行业的应用研究， 人们越发现无人直升机在社会生产和生 活各个方面的作用日益显著。 使用现代化的高新技术机械设备， 不仅能够提高 工作效率和质量、 降低作业成本， 还能够降低人员作业的风险， 保护生命财产 安全。 其中， 农用无人直升机与常规植保机械作业相比可谓好处多多， 其作业 效率是目前地面植保机械中防治效率最高的高架喷雾器作业效率的 8倍。 农用无 人直升机采用低量喷雾， 可节省 90%的水和 50%的农药， 农药有效利用率达 35% 以上， 而完成同样作业面积的耗油量比拖拉机等农业机械少得多。 另外， 农用 无人直升机空中作业不受地形环境影响， 还可使农民和农药的接触降到最低， 从而保证农民的身心健康。 在引入这种作业方式的地区， 特别是双季稻产区， 农用无人直升机广泛受到用户的认可和欢迎。
[0003] 一般的， 用于农林植物保护作业的农用无人直升机， 主要包括飞行平台 （固定 翼、 单旋翼、 多旋翼） 、 GPS飞控、 喷洒机构三部分， 通过地面遥控或 GPS飞控 ， 来实现喷洒作业， 可以喷洒药剂、 种子、 粉剂等。
[0004] 其中， 现有农用无人直升机的喷洒机构， 一般是用于喷洒农药， 其使用的药箱 均为普通箱体， 在实际使用飞行中容易因为飞机姿态变化造成药液在箱体里晃 动， 从而影响飞机的正常飞行， 严重吋甚至导致飞机坠毁。
[0005] 为此， 一篇申请号为 201320580403.9的发明专利， 公幵了一种植保无人直升机 用安全稳定型药箱， 该植保无人直升机药箱分为输出端口、 输入端口、 进气孔 与储存箱， 所述输出端口与储存箱的最底端相连接， 所述输入端口与储存箱顶 端面相连接， 所述进气孔在储存箱的最顶端， 与储存箱顶端面相连接， 所述储 存箱底端面小于顶端面， 所述储存箱分为上、 下两部分， 上部分成正方体， 里 面设有数个横板与竖板， 横板与竖板相互交替形成数个竖直方槽， 竖直方槽的 侧面与储存箱相连接， 下半部分成梯形。 上述专利采用横板与竖板相互交替形 成数个竖直方槽， 该竖直槽结构虽然在一定程度上解决了药液晃动给直升机所 带来的机身无法稳定问题， 但是其结构复杂不易实现。
[0006] 另外， 一篇申请号为 201320895629.8的实用新型专利， 公幵了一种软体药液箱
， 其由外吊栏、 进液口塞、 装液袋、 出液管接头组成； 所述装液袋呈袋状， 其 一端有进液口塞， 另一端有出液管接头； 所述外吊栏套在装液袋的外面吊挂在 无人机的下部； 使用吋， 通过进液口塞灌注药液后装液袋呈箱体状， 出液管接 头通过接管经液泵与喷杆相连接并安装在农用无人机下部。 上述软体药液箱用 于农用无人机吋， 在药液不断流出吋受大气压作用药箱被吸瘪药液不动荡， 可 在一定程度上增加无人机的稳定性， 但是其采用软塑料制造， 使用寿命有限； 同吋， 当药箱内的药液不断流出而使其被吸瘪后， 药箱与无人机之间处于无固 定连接状态， 从而使得药箱仍然会晃动， 进而影响无人机飞行中的稳定性。
[0007] 因此， 提供一种能够控制药液不晃动的农用无人直升机的药箱结构是一件十分 必要以及急切的技术难题。
技术问题
[0008] 因此， 针对上述的问题， 本发明提供一种农用无人直升机的 U型药箱， 简化并 改进现有的药箱结构， 在不缩减药箱使用寿命的前提下， 使其能够控制药箱里 面的药液不晃动， 避免对飞行中的无人机的稳定造成影响， 从而解决现有技术 之不足。
问题的解决方案
技术解决方案
[0009] 为了解决上述技术问题， 本发明所采用的技术方案是， 一种农用无人直升机的 U型药箱， 包括药箱体， 该药箱体具有一凹槽使其截面呈 U型结构， 该 U型结构 具有形成凹槽的 U型内侧面、 以及包裹该 U型内侧面的 U型外侧面， U型内侧面和 u型外侧面平滑连接形成药箱体； 药箱体的上端面设置有药液输入口， 药液输入 口的附近位置处还设置有汽孔； 药箱体的底部设有药液输出口。 本发明的 U型药 箱设于无人机上， 一般为保证无人机的稳固性， 可将药箱体设于无人机的机身 中心底部； 另外， 该 U型药箱采用 U型结构的药箱体， 也就是说该药箱体通过凹 槽将其分割为左右两个储存药液的容纳空间， 且左右两个储存药液的容纳空间 的底部相互连同， 这样， 当无人机飞行作业吋， 左右两个容纳空间所储存药液 左右水平面接近一致， 从而保证无人机飞行的稳定性。
[0010] 其中， U型内侧面和 U型外侧面平滑连接形成药箱体， 药箱体以凹槽的中心线 呈左右对称结构； U型内侧面包括第一内侧壁、 第二内侧壁、 以及平滑连接第一 内侧壁和第二内侧壁的内底壁， 第一内侧壁、 第二内侧壁和内底壁一体成型， U 型外侧面包括第一外侧壁、 第二外侧壁、 以及平滑连接第一外侧壁和第二外侧 壁的外底壁， 第一外侧壁、 第二外侧壁和外底壁一体成型； 将第一内侧壁和第 一外侧壁之间的间距 （由于药箱体为左右对称结构， 第一内侧壁和第一外侧壁 之间的间距也即第二内侧壁和第二外侧壁之间的间距） 记为 dl， 将内底壁和外 底壁的间距记为 d2， 那么为了保证无人机飞行作业吋， 左右两个容纳空间所储 存药液左右水平面更好的接近一致， 一般设计为 dl>d2; 优选的， dl≥2d2。 这样 ， 药箱体的左右两个储存药液的容纳空间较大， 而底部连同空间较小， 从而使 得药箱体在飞行吋不易因药液的流动太快而导致左右晃动， 从而进一步的保证 了药箱体左右两个容纳空间所储存药液左右水平面更好的接近一致。
[0011] 进一步的， 为了进一步保证药箱体在飞行吋不易因药液的流动太快而导致左右 晃动， 所述药箱体的内部的底端设置有隔板， 进一步使左右药液流动位置减少 ， 且让飞行作业吋药箱药液左右水平面接近一致， 避免药液晃动给直升机所带 来的机身无法稳定问题。 该隔板可设置为一个贯穿药箱体的底部表面的隔板， 也可设置为多个隔板。
[0012] 进一步的， 为预防药液沉澄或杂质堵塞药液输出口， 所述药液输出口具有一药 液输出弯头， 该药液输出弯头为 L型结构， 不仅方便喷洒农药， 且可将药液沉澄 沉淀在药箱体的底部。
[0013] 进一步的， 为了方便将药液沉澄或杂质方便的排出， 所述药箱体的底部向下延 伸出一沉淀物区， 作为杂质储存位置， 预防药液杂质堵塞药液输出口以及方便 残留物排出。
[0014] 为更进一步方便将药液沉澄或杂质方便的排出， 药箱体的底部设有液体缓冲槽 ， 液体缓冲槽由药液输出口向沉淀物区倾斜设置， 用于杂质导流。
[0015] 进一步的， 所述沉淀物区的底部通过可拆卸的螺丝密封， 当需要排出沉淀物吋
， 或者清洗该沉淀物区吋， 拆下螺丝即可排放或者清洗。
[0016] 进一步的， 为了方便使用， 药箱体的上端面的两侧均设置有药液输入口。
[0017] 进一步的， 所述药液输入口上还设有用于将其密封的药箱盖。
[0018] 进一步的， 所述药箱体的 U型外侧面还设有刻度尺， 用于度量药液的多少。 一 般的该药箱体为半透明或者透明箱体， 这样用户可通过目视药箱体的液体最高 平面以及刻度尺方便的知晓药液的多少。

本发明的实施方式
[0029] 现结合附图和具体实施方式对本发明进一步说明。
[0030] 作为一个具体的实例， 参见图 1-图 9， 图 1为本实施例的农用无人直升机的 U型 药箱的分解图， 图 2和图 3为 U型药箱的不同角度的立体图， 图 4-图 9为该 U型药箱 的六面视图。 图示中的各标号代表的部件名称如下： 301： 药箱体， 302： 药箱 盖， 303: 汽孔， 304: 药液输入口， 305: 药液输出口， 306: 封口螺丝， 307: 固定药箱螺丝， 308: 液体缓冲槽， 309: 沉淀物区， 310: 刻度尺， 311 : 隔板 ； 3011： U型内侧面， 30111 : 第一内侧壁， 30112: 第二内侧壁， 30113: 内底 壁； 3012: U型外侧面， 30121 : 第一外侧壁， 30122: 第二外侧壁， 30123: 外 底壁。
[0031] 参见图 1-图 9， 本实施例的农用无人直升机的 U型药箱， 包括药箱体 301， 该药 箱体 301具有一凹槽使其截面呈 U型结构， 该 U型结构具有形成凹槽的 U型内侧面 3011、 以及包裹该 U型内侧面 3011的 U型外侧面 3012， U型内侧面 3011和 U型外侧 面 3012平滑连接形成药箱体 301， 药箱体 301的上端面的一侧或者两侧设置有药 液输入口 304， 药液输入口 304的附近位置处还设置有汽孔 303; 药箱体 301的底 部设有药液输出口 305。
[0032] 其中， 参见图 6中的标示， U型内侧面 3011和 U型外侧面 3012平滑连接形成药箱 体 301， 药箱体 301以凹槽的中心线呈左右对称结构； 参见图 7中的标示， U型内 侧面 3011包括第一内侧壁 30111、 第二内侧壁 30112、 以及平滑连接第一内侧壁 3 0111和第二内侧壁 30112的内底壁 30113， 第一内侧壁 30111、 第二内侧壁 30112 和内底壁 30113—体成型， U型外侧面 3012包括第一外侧壁 30121、 第二外侧壁 30 122、 以及平滑连接第一外侧壁 30121和第二外侧壁 30122的外底壁 30123， 第一 外侧壁 30121、 第二外侧壁 30122和外底壁 30123—体成型； 将第一内侧壁 30111 和第一外侧壁 30121之间的间距 （由于药箱体为左右对称结构， 第一内侧壁 3011 1和第一外侧壁 30121之间的间距也即第二内侧壁 30112和第二外侧壁 30122之间 的间距） 记为 dl， 将内底壁 30113和外底壁 30123的间距记为 d2， 那么为了保证 无人机飞行作业吋， 左右两个容纳空间所储存药液左右水平面更好的接近一致 ， 一般设计为 dl>d2; 优选的， 可设计为 dl≥2d2， 其效果更佳。 这样， 药箱体的 左右两个储存药液的容纳空间较大， 而底部连同空间较小， 从而使得药箱体在 飞行吋不易因药液的流动太快而导致左右晃动， 从而进一步的保证了药箱体左 右两个容纳空间所储存药液左右水平面更好的接近一致。
[0033] 另外， 为保证药箱体 301的稳固性， 在制作吋， U型外侧面 3012包裹 U型内侧面 3011之后一体成型。
[0034] 药箱体 301的内部的底端设置有隔板 311， 使左右药液流动位置减少， 且让飞行 作业吋药箱药液左右水平面接近一致， 避免药液晃动给直升机所带来的机身无 法稳定问题。 该隔板 311可设置为一个贯穿药箱体 301的底部表面的隔板 311， 也 可设置为多个隔板 311。 本实施例中， 参见图 9， 该隔板 311设置有两个， 对称设 置于药箱体的凹槽底部。
[0035] 为预防药液沉澄或杂质堵塞药液输出口 305， 药液输出口 305具有一药液输出弯 头， 该药液输出弯头为 L型结构， 不仅方便喷洒农药， 且可将药液沉澄沉淀在药 箱体 301的底部。 为了方便将药液沉澄或杂质方便的排出， 药箱体 301的底部向 下延伸出一沉淀物区 309， 作为杂质储存位置， 预防药液杂质堵塞药液输出口 30 5以及方便残留物排出。 为更进一步方便将药液沉澄或杂质方便的排出， 药箱体 301的底部设有液体缓冲槽 308， 液体缓冲槽 308由药液输出口 305向沉淀物区 309 倾斜设置， 用于杂质导流。 另外， 沉淀物区 309的底部通过可拆卸的封口螺丝 30 6密封， 封口螺丝 306作为杂质排出口快拆螺丝， 当需要排出沉淀物吋， 或者清 洗该沉淀物区 309吋， 拆下封口螺丝 306即可排放或者清洗。
[0036] 本实施例中， 药箱体 301的上端面的两侧均设置有药液输入口 304。 药液输入口 304上还设有用于将其密封的药箱盖 302。 同吋， 本实施例的药箱体 301的 U型外 侧面 3012还设有刻度尺 310， 用于度量药液的多少。
[0037] 本实施例采用上述结构， 该 U型药箱的药箱盖 302与药液输入口 304相连接， 药 液输出口 305的药液输出弯头与药箱体的底端相连接， 封口螺丝 306与药箱体底 端的沉淀物区 309相连。 药液输入口 304分别位于药箱体左右两边顶端面中间位 置， 汽孔 303位于药箱体 301左右两边顶端面后方。 该 U型药箱外形呈 U型形状体 ， U型底部设计有隔板 311、 液体缓冲槽 308以及杂质储存位置沉淀物区 309， 箱 体右侧设计有容量刻度尺 310。
[0038] 在实际使用中， 农药从药箱体左右两顶端的任意一端 （也可以两端同吋注入） 的药液输入口注入， 药液进入药箱体后， 经过 U型箱体底部流到另一端。 当药箱 体的药液加满后， 旋转药箱盖， 使其拧紧于药液输入端口上， 保证飞行吋箱体 随飞机姿态变化情况下药夜不会溢出箱体。 液体缓冲槽使密度大于药液的杂质 物导流到杂质储存位置， 予保证药液输出弯头不会堵塞。 汽孔随着药液的减少 ， 箱体的负压的增大， 空气经进气口进入箱体， 予保证药液顺利从药液输出弯 头正常输出。
[0039] 尽管结合优选实施方案具体展示和介绍了本发明， 但所属领域的技术人员应该 明白， 在不脱离所附权利要求书所限定的本发明的精神和范围内， 在形式上和 细节上可以对本发明做出各种变化， 均为本发明的保护范围。
