图 1示出了本发明一些实施例中的清洁车 1，该清洁车 1可为道路洗扫 车， 该清洁车 1包括底盘 10以及安装于底盘 10上的清扫系统 20、 清洗系 统 30、 回收系统 40和垃圾箱。
清扫系统 20在一些实施例可包括设置在底盘 10车架下方且位于前后 车桥之间的扫盘组件 21以及驱动扫盘组件 21转动的驱动装置 23， 扫盘组 件 21的数量可以是两个， 并横向并排设置。可以理解地，在一些实施例中， 扫盘组件 21的数量也可以为四个， 分成两对， 呈前后错开排列， 并且这两 对扫盘组件 21中一对可横向伸展到底盘侧身外侧， 以增加清扫面积。 可以 理解地， 在另一些实施例中， 该清扫系统 20还可以包括滚扫组件， 该滚扫 组件一般横向设置扫盘组件 21 的后方， 以对扫盘组件 21 间的间隙进一步 清扫。
清洗系统 30用于产生高压清水对清扫系统 20清扫过的路面进行冲洗， 使路面更加清洁， 其包括高压水泵 31、 喷嘴 33、 将与高压水泵 14的入水 口与垃圾箱相连通的进水管 35以及将高压水泵 31的出水口与喷嘴 33连通 的出水管 37。 喷嘴 33在一些实施例中可设置在底盘 10下方并位于扫盘组 件 21的后方， 以对扫盘组件 21清扫过的路面进行高压冲洗。
回收系统 40用于对清扫系统 20及清洗系统 30产生的垃圾和污水抽吸 至垃圾箱中， 其包括与垃圾箱连通的风机 41、 吸嘴 43以及进水进风管 45。 吸嘴 43设置在底盘 10车架下方与地面之间的间距较小， 且与喷嘴 33相邻 近， 以便能够将冲洗地面后形成的污水快速地抽吸到垃圾箱中， 进水进风 管 45将吸嘴 43与垃圾箱连通。 工作过程中， 风机 41使箱体总成内产生负 压， 将经过扫盘组件 21扫起的垃圾以及喷嘴 33喷出的高压清水冲洗地面 后产生的垃圾或污水， 通过吸嘴 43及进水进风管 45吸入到垃圾箱内。
一同参阅图 2， 垃圾箱在一些实施例中可包括箱体 50及箱门 60， 箱体
50略呈长方体构造， 其后端具有用于排放垃圾的开口， 箱门 60铰接于箱体 50的后侧， 用于封闭该开口。 箱体 50中具有一个隔板 51， 该隔板 51由箱 体 50前侧至后侧逐渐向下倾斜设置， 将箱体 50的内部空间分隔成上下两 个腔室， 即第一腔室 53及第二腔室 55， 第一腔室 53具有第一开口 531， 第二腔室 55具有第二开口 551， 第一开口 531及第二开口 551是由隔板 51 将箱体 50的后端的开口分隔而成。第一腔室 53与回收系统 40的进水进风 管 45连通， 回收系统 40抽吸上来的垃圾和污水直接进入到第一腔室 53。 第二腔室 55用来收容处理后的污水， 其与清洗系统 30的进水管 35连通， 第二腔室 55中还可以设置中水处理装置 57，以对过滤后形成的中水进一步 处理， 使之符合再次利用来冲洗路面的要求。 在一些实施例中， 中水处理 装置 57与清洗系统 30的进水管 35连通， 以使处理后的净化水被重新用来 冲洗地面。 如此， 污水回收后， 循环利用， 延长一次加水的作业时间， 节 约用水， 无需中途排放污水， 减少加水次数。
箱门 60具有两个封闭区域 67及 68， 分别与第一开口 531以及第二开 口 551对应， 以封闭该第一腔室 53及第二腔室 55。 箱门 60中还具有用于 将第一腔室 53与第二腔室 55连通的导流通道以及覆盖在导流通道入水端 的过滤装置 65，过滤装置 65用以对污水从第一腔室 53流入第二腔室 55中 时的进行过滤。 另外， 箱门 60上还可设置防堵装置 66， 以防止过滤装置 65在工作过程中产生堵塞。
如图 3至图 8所示， 箱门 60在一些实施例中可包括门面板 61、设置在 门面板 61外侧的外加强结构 62、 设置在门面板 61内侧的分隔结构 63、 设 置在门面板 61内侧的内加强结构 64、 设置在分隔结构 63和内加强结构 64 上的过滤装置 65以及设置在门面板 61外侧的防堵装置 66。
如图 3及图 7所示，门面板 61大体呈矩形，其包括矩形的面板本体 611 以及位于面板本体 611周缘的折边 612。 门面板 61可采用强度高、 防腐性 能佳的板材制成， 如钢板等。
再如图 3所示， 外加强结构 62包括横向设置在门面板 61下侧缘附近 的第一加强件 621、 纵向设置门面板 61左侧的第二加强件 623、 纵向设置 在门面板 61右侧的第三加强件 625以及横向设置在第二加强件 623与第三 加强件 625之间第四加强件 627。第二加强件 623及第三加强件 625均从门 面板 61的上侧缘垂直向下延伸至与第一加强件 621连接。 第一加强件 621 可采用矩形钢板制成， 其设置在门面板 61的下侧缘附近， 可以提高门面板 61下侧缘的强度； 第二加强件 623及第三加强件 625均可采用 U形钢板制 成， 并采用开口朝向门面板 61的方式固定在门面板 61上， 其一个方面可 以提高箱门 1 的强度， 另一个方面还可以起到导流结构的作用。 第四加强 件 627位于门面板 61的下侧与第一加强件 621邻近， 其两端分别与第二加 强件 623及第三加强件 27相连， 第四加强件也可以采用 U性钢材制成， 其 可以进一步提高箱门 1抗扭的能力。
箱门 60在一些实施例中还可包括两个门转座 613、 两个视窗孔 615以 及污水放水阀 614。该两个门转座 613用于将箱门 60铰接在箱体 50上， 其 分别固定在第二加强件 623及第三加强件 625的上端， 并与门面板 61的上 端缘相连； 第二加强件 623及第三加强件 625的设置可使门面板 61的受力 更加均匀， 防止门面板 61与门转座 613结合处由于应力过于集中而造成损 坏。 两个视窗孔 615分别设置在门面板 61左侧的上、 下方， 用于观察垃圾 箱中的状况， 诸如污水、 垃圾的上限及下限位置信息。 污水放水阀 614设 置在门面板 61右侧的下方， 可以根据需要排出污水垃圾箱体中的污水。
一同参阅图 4至图 6，分隔结构 63可用于将箱门 60的内侧分隔出两个 封闭区域， 即分别为位于上部的较大第一区域 67以及位于第一区域 67下 方的第二区域 68，该两个第一区域 67及第二区域 68分别对应于箱体 50内 部的两个腔室 53及 55的开口端 531及 551， 以封闭开口端 531及 551， 当 箱门 60关闭时， 该两个腔室 53及 55相互独立。
再如图 5及图 6所示， 分隔结构 63包括设置在门面板 61上部的倒 U 形的第一分隔件 631、 与第一分隔件 631合围成第一区域 67的长条状第二 分隔件 632、 设置在门面板 61下部的 U形第三分隔件 633以及与第三分隔 件 633合围成第二区域 68的第四分隔件 634。 第一分隔件 631及第三分隔 件 633可以采用矩形钢材制成， 其设置在门面板 61的内侧面的周缘， 并且 两者之间以及两者与门面板 61的折边 612之间均留有一定的间隔， 这些间 隔中填充有密封件 637。第二分隔件 632以及第四分隔件 634均可采用角钢 制成， 两者平行间隔排列， 两者之间隔中也填充有密封件 637。 如此， 第一 区域 67及第二区域 68周围均围绕有密封件 637,当箱门 10关闭时， 密封件 637密封在腔室 53及 55的开口端 531及 551边缘， 从而实现对腔室 53及 55的封闭。
再如图 5所示， 门面板 61的内侧面还可以布置有内加强结构 64， 以进 一步提高箱门 60的强度， 该内加强结构 64包括与门面板 61外侧面的第二 加强件 623的位置对应且呈垂直布置的第一内加强件 641及第二内加强件 642， 与第三加强件 625的位置对应且呈垂直布置的第三内加强件 643及第 四内加强件 644，以及横向连接于第一内加强件 641与第三内加强件 643之 间的第五内加强件 645。 在一些实施例中， 这些内加强件均可以采用 U形 钢板制成， 并可以通过焊接的方式以开口侧朝向门面板 61的方式固定到门 面板 61的内侧面上。
再如图 6所示， 门面板 61上部位于第一区域 67内开设有两个第一穿 孔 616、 617， 该两个第一穿孔 616、 617均可呈矩形， 并贯穿门面板 61， 分别与门面板 61外侧面的第二加强件 623以及第三加强件 625的上部连通。 门面板 61下部位于第二区域 68内开设有两个第二穿孔 618、 619， 该两个 第二穿孔 618、 619也可呈矩形， 并贯穿门面板 61， 分别与第二加强件 623 以及第三加强件 625的下部连通。 第二加强件 623以及第三加强件 625均 可采用 U形钢材制成， 具有纵向槽道， 该两者之槽道可以分别将第一穿孔 616、 617与第二穿孔 618、 619连通。 另夕卜， 第一内加强件 641及第三内加 强件 643分别覆盖第一穿孔 616及 617，第二内加强件 642及第四内加强件 644分别覆盖第二穿孔 618及 619。
在一些实施例中， 由于第一内加强件 641及第三内加强件 643分别覆 盖了第一穿孔 616及 617， 可分别在第一内加强件 641与第三内加强件 643 的内侧壁上各开设一第一通孔 648 (如图 7及图 8所示）。 同样， 由于第二 内加强件 642及第四内加强件 644分别覆盖了第二穿孔 618及 619，可分别 在第二内加强件 642及第四内加强件 644的顶壁上各开设一个第二通孔 649 (如图 5及图 7所示）。如此，两个第一通孔 648，第一穿孔 616、 617,第二、 第三加强件 623、 625， 两个第二穿孔 618、 619， 以及两个第二通孔 649便 构成了连通第一区域 67及第二区域 68的两个并联的导流通道， 其中， 两 个第一通孔 648分别构成该两个导流通道的进水端， 两个第二通孔 649分 别构成该两个导流通道的出水端。 可以理解地， 第一通孔 648及第二通孔 649的位置并不局限于上述布置， 根据需要其也可以进行调整。
图 5 中的箭头示出了污水在其中一个导流通道中的走向示意图， 如图 所示， 污水经过过滤装置 65过滤后， 从第一内加强件 641内侧壁上的第一 通孔 648进入到第一内加强件 641内， 再经由门面板 61上与第一内加强件 对应的第一穿孔 616进入第二加强件 623中， 在第二加强件 623中沿着槽 道向下流动直到第二穿孔 618处， 再经由第二穿孔 618进入到第二内加强 件 642中， 最后经由第二内加强件 642上的第二通孔 649流出。
再如图 7及图 8所示， 过滤装置 65罩设在箱门 60的第一区域 67的内 侧， 其包括外过滤网 651、 中过滤网 652以及内过滤网 653。 在一些实施例 中， 外过滤网 651 呈多孔罩状， 其过滤孔径相对较大， 其主要用于过滤掉 污水中的较大颗粒的垃圾。中过滤件 62也呈多孔罩状，其位于外过滤网 651 内侧， 以对经过外过滤网 61过滤过的中水进一步过滤， 中过滤网 652的过 滤孔径小于外过滤网 651。 内过滤网 653呈多孔平板状， 其用于对经过中过 滤网 652过滤过后的中水进一步过滤，其过滤孔径小于中过滤网 652。如此， 污水能够通过过滤装置 65 能够进行三级过滤。 可以理解地， 过滤装置 65 的过滤级数并不局限于三级， 其级数可以根据需要进行增加或减少。
再如图 5及图 8所示， 内过滤网 653包括入水侧以及与入水侧相对的 出水侧， 内过滤网 653的四周缘可通过螺丝分别固定到第一内加强件 641、 第三内加强件 643、第五内加强件 645以及第一分隔件 631上， 并与第一内 加强件 641、 第三内加强件 643、 第五内加强件 645、 第一分隔件 631以及 门面板 611—道界定出位于内过滤网 653出水侧的滤水空间 654。中过滤网 652可固定在第一内加强件 641和第三内加强件 643上，外过滤网 651可固 定在第一分隔件 631上。
再如图 8所示， 防堵装置 66包括气源 （图未示）、 气管 661、 脉冲阀 662以及喷头 663，气源用于提供压缩气体，其通过气管 661连接到喷头 663， 脉冲阀 662设置在气管 661上， 喷头 663安装在箱门 60的门面板 611上， 贯穿门面板 611伸入到滤水空间 654中， 并朝向过滤装置 65。 气源在一些 实施例中可为压缩空气源。
在运行过程中， 只需控制脉冲阀 662在一定时间间隔内开启或关闭， 即可通过气管 661将气源内的压缩空气输送至喷头 663，由喷头 663间隔地 朝向过滤装置 65及滤水空间 654中的中水喷入压缩空气， 从而利用脉冲空 气清理过滤装置 65上的堵塞物， 使附着在过滤装置 65上的垃圾或漂浮于 水面或沉于水底， 从而起到对过滤装置 65的防堵功能。
值得说明的是， 由于内过滤网 653在一些实施例中可为较细的过滤网 制成， 例如 35目~100目， 污水中的轻漂物、 砂粒等杂质容易将其堵塞， 防 堵装置 66产生的脉冲空气不停地朝向内过滤网 653及滤水空间 654中的水 进行脉冲， 可将堵在内过滤网 653上的垃圾较好地冲出滤孔， 轻漂物冲到 水面， 泥沙抖落到箱体 50的底部， 可实现内过滤网 653的防堵功能。
以上所述仅是本发明的优选实施方式， 本发明的保护范围并不仅局限 于上述实施例， 凡属于本发明思路下的技术方案均属于本发明的保护范围。 应当指出， 对于本技术领域的普通技术人员来说， 在不脱离本发明原理前 提下的若干改进和润饰， 这些改进和润饰也应视为本发明的保护范围。
