Description

能够按照预设液位将容器内液体排出的定量排液装置 技术领域
本发明涉及用于液体容器的配件， 尤其是涉及用于排出容器内液体的装置。 背景技术
对于大型液体容器， 如何将其中容置的液体排出是使用者经常会遇到的问题。 例如， 为 确保水质， 水族养殖箱需要定期更换其中的液体。 现有技术通常釆用的将液体容器内液体排 出的方法包括机器排液和人工排液。 机器排液就是利用水泵将容器内的液体排出。 人工排液 最简单的就是用小容器连续不断地将容器内的液体舀出， 例如， 用水瓢或者大勺。 还有一种 常用的人工排液法是根据虹吸原理用水管将容器内的液体排出。 但是无论釆用上述哪一种排 液方法都需要有人监控排液过程， 需要付出人工成本。 尤其是对于水族养殖箱的排液操作， 由于有不打捞箱内水族但要完成箱内水体更换的需求， 更换水族养殖箱内液体常常不排出箱 内全部液体， 而是需要定量排水， 而且排水量也会根据需要做出相应调整， 因此水族养殖箱 的排液过程更加需要被监控； 而对于水族集中养殖场合， 各水族养殖箱有不同的排液量要求， 釆用现有技术的排液法就更需要大量人员专门监控排液过程， 令人工成本消耗量更大。
因此需要一种技术能够使排液操作人员免受排液监控的困扰。 发明内容
本发明要解决的技术问题在于避免现有技术的不足之处而提出一种能够按照设定的液位 将容器内液体排出的定量排液装置。
本发明解决所述技术问题可以通过釆用以下技术方案来实现：
一种能够按照预设液位将容器内液体排出的定量排液装置， 包括安装在液体容器内的、 管状的排液管。 所述排液管开设有径向贯穿该排液管管壁的全排排液口， 所述排液管固定安 装在液体容器内， 所述全排排液口位于液体容器内的液位最低处， 借助该全排排液口能够将 液体容器内的全部液体排出。 尤其是， 还包括管状的外套管和液位控制杆。 所述排液管还开 设有径向贯穿该排液管管壁的、 位于全排排液口之上的、 至少一个内定液位排液口。 所述外 套管套装在所述排液管外， 该外套管开设有与内定液位排液口数量相同的、 径向贯穿所述外 套管管壁的外定液位排液口。 当所述外套管的近底部管壁覆盖全排排液口时， 所述各外定液 位排液口分别与各内定液位排液口的位置一一对应。 所述液位控制杆的管壁可滑动地容置于 所述排液管的管壁与外套管的管壁之间。 所述液位控制杆开设有一径向贯穿该液位控制杆管 壁的导流口。 在所述外套管与液位控制杆的管壁间设置有滑动定位组件， 借助该滑动定位组 件， 液位控制杆的导流口能够被分别定位在各该对应的内定液位排液口与外定液位排液口之 间， 从而能够将排液管管壁内的空间与液体容器内的空间连通， 并且凭借液位控制杆的管壁 阻隔位于导流口下方的内定液位排液口与外定液位排液口连通。 而且， 借助所述滑动定位组 件， 当所述导流口被定位在一对位置相同的内定液位排液口与外定液位排液口之间时， 所述 外套管与液位控制杆联动， 从而该外套管能够随液位控制杆沿它们的中心轴线位移。 具体而言， 所述滑动定位组件包括设置在液位控制杆的管壁外侧面上的、 至少一处往外 凸出的凸台， 加工在外套管的管壁内面上至少一处径向往内 G3进的滑槽， 以及加工在外套管 的管壁内面上至少一处径向往内 G3进的环状柱面定位槽。 所述滑槽与定位槽连通， 借助在所 述滑槽内滑动的凸台， 液位控制杆沿轴向位移。 而凸台在所述定位槽内时， 液位控制杆只能 转动而不能沿轴向位移， 从而将所述导流口定位在一对位置相同的内定液位排液口与外定液 位排液口之间。
更具体地， 所述排液管开设有两个内定液位排液口， 相应地所述外套管也开设有两个外 定液位排液口。 在所述外套管的最上部内面设置有沿该外套管轴向伸展的、 两条平行的滑槽， 所述定位槽位于两滑槽下方， 并且与该两滑槽连通。 所述液位控制杆上设置有分别与所述两 滑槽位置相应的两凸台。 当所述两凸台从两滑槽滑入定位槽内时， 所述液位控制杆的导流口 位于最低的一对内定液位排液口与外定液位排液口之间。
所述排液管的顶部管口封闭。所述排液管的底部管口从液体容器的底面伸出该液体容器， 作为所述定量排液装置的排液口。 所述底部管口被可拆卸地封闭。
所述定量排液装置还包括垫片， 该垫片借助超声波工艺或者粘结工艺安装在所述排液管 的顶部管口， 用于封闭该排液管的顶部管口。
所述定量排液装置还包括胶塞，借助该胶塞实现对所述排液管的底部管口可拆卸的封闭。 具体地， 所述排液管的管壁包括下排液管壁和上排液管壁。 所述下排液管壁的外径大于 上排液管壁的外径。 所述外套管的底部管壁的内侧能够紧贴在下排液管壁的外侧滑动。 所述 液位控制杆的管壁在所述上排液管壁的外侧面与外套管的管壁内侧面之间滑动。
为防止所述液位控制杆从排液管与外套管之间拉出脱离。 所述液位控制杆的管壁包括下 控制管壁和上控制管壁。 所述下控制管壁的内径大于上控制管壁的内径。 所述排液管的顶部 设置有沿径向伸出该排液管管壁的至少一卡钩。 该卡钩外径大于排液管管壁外径。 所述下控 制管壁的内侧面紧贴排液管的管壁外侧面在卡钩下方滑动。
所述液位控制杆还包括拉帽， 该拉帽罩盖在所述液位控制杆的顶部管口， 从而将所述液 位控制杆的顶部管口封闭。
为防止漏液， 在所述排液管的全排排液口和各内定液位排液口的上方和下方都设置有密 封圈。 同现有技术相比较， 本发明 "能够按照预设液位将容器内液体排出的定量排液装置" 的 技术效果在于：
通过操作液体控制杆， 设定排水后液体容器内的液位后就可以实施排液， 排液过程不需 要专门监控， 使操作人员摆脱了监控排液过程带来的麻烦， 节省了人工成本。 附图说明

本发明提出一种能够按照预设液位将容器内液体排出的定量排液装置， 如图 1至图 8所 示， 包括安装在液体容器 9内的、 管状的排液管 1。 所述排液管 1开设有径向贯穿该排液管 1 管壁的全排排液口 10, 所述排液管 1固定安装在液体容器 9内， 所述全排排液口 10位于液 体容器 9内的液位最低处，借助该全排排液口 10能够将液体容器 9内的全部液体排出。所述 定量排液装置还包括管状的外套管 2和液位控制杆 3。 所述排液管 1还开设有径向贯穿该排 液管 1管壁的、 位于全排排液口 10之上的、 至少一个内定液位排液口 11。 所述外套管 2套 装在所述排液管 1外， 该外套管 2开设有与内定液位排液口 11数量相同的、径向贯穿所述外 套管 2管壁的外定液位排液口 21。 当所述外套管 2的近底部管壁覆盖全排排液口 10时， 所 述各外定液位排液口 21分别与各内定液位排液口 11的位置一一对应。 所述液位控制杆 3的 管壁可滑动地容置于所述排液管 1的管壁与外套管 2的管壁之间。 所述液位控制杆 3开设有 一径向贯穿该液位控制杆 3管壁的导流口 32。 在所述外套管 2与液位控制杆 3的管壁间设置 有滑动定位组件，借助该滑动定位组件， 液位控制杆 3的导流口 32能够被分别定位在各该对 应的内定液位排液口 11与外定液位排液口 21之间， 从而能够将排液管 1管壁内的空间与液 体容器 9内的空间连通，并且凭借液位控制杆 3的管壁阻隔位于导流口 32下方的内定液位排 液口 11与外定液位排液口 21连通。 而且， 借助所述滑动定位组件， 当所述导流口 32被定位 在一对位置相同的内定液位排液口 11与外定液位排液口 21之间时， 所述外套管 2与液位控 制杆 3联动， 从而该外套管 2能够随液位控制杆 3沿它们的中心轴线位移。 本发明借助液位 控制杆的管壁阻隔对应的内、 外定液位排液口 11、 21 , 只有将导流口 32定位在一对液位高 度相同的内、 外定液位排液口 11、 21之间时， 才能将排液管 1与液体容器 9联通， 使液体容 器 9内的液体排出， 并且排出的液体是液体容器 9中在导流口所在液位之上的液体， 实现定 量排液。 而且， 只要设定好排液高度， 即设定液位控制杆 3的导流口 32的定位位置， 不需要 人工监控就能完成液体排出， 较现有技术大大节省人工成本。
本发明优选实施例， 如图 1所示， 所述滑动定位组件包括设置在液位控制杆 3的管壁外 侧面上的、 至少一处往外凸出的凸台 41 , 加工在外套管 2的管壁内面上至少一处径向往内 G3 进的滑槽 42,以及加工在外套管 2的管壁内面上至少一处径向往内 G3进的环状柱面定位槽 43。 所述滑槽 42与定位槽 43连通， 借助在所述滑槽 42内滑动的凸台 41 , 液位控制杆 3沿轴向 位移。 而凸台 41在所述定位槽 43内时， 液位控制杆 3只能转动而不能沿轴向位移， 从而将 所述导流口 32定位在一对位置相同的内定液位排液口 11与外定液位排液口 21之间。所述定 位槽 43与凸台 41配合用于完成对液位控制杆 3的定位， 各定位槽 43根据各对内、 外定液位 排液口 11、 21之间的距离分别设定在不同高度上。 所述滑槽 42主要用于联通各定位槽 42, 并引导凸台 41在滑槽 42内滑动以进入各定位槽 43中。所述滑动定位组件还可以是成对地分 别设置外套管 2的管壁与液位控制杆 3之间的 G3坑和滚珠， 借助滚珠实现液位控制杆 3的滑 动， 借助滑入 G3坑的滚珠实现液位控制杆 3的定位。
本发明优选实施例实现三级水位排水， 设置了两对内、 外定液位排液口 11、 21 , 用于实 现以两个液位高度和全部排出液体的三级排水功能。 所述排液管 1开设有两个内定液位排液 口 11 , 相应地所述外套管 2也开设有两个外定液位排液口 21。 在所述外套管 2的最上部内面 设置有沿该外套管 2轴向伸展的、 两条平行的滑槽 42, 所述定位槽 43位于两滑槽 42下方， 并且与该两滑槽 42连通。 所述液位控制杆 3上设置有分别与所述两滑槽 42位置相应的两凸 台 41。 当所述两凸台 41从两滑槽 42滑入定位槽 43内时， 所述液位控制杆 3的导流口 32位 于最低的一对内定液位排液口 11与外定液位排液口 21之间。 本实用新型优选实施例釆用中 心线是直线的直线滑槽 42, 还可以釆用中心线是螺旋线的滑槽， 使液位控制杆 3旋转着上下 位移。
为防止液体容器 9内的从排液管 1顶部流进排液管 1内，所述排液管 1的顶部管口 15封 闭。 本发明适用人工排液和机器排液， 机器排液可以将水泵泵水管插入排液管内底部。 本发 明优选实施例， 釆用的方案相比机器排液更为简单， 即所述排液管 1的底部管口 14从液体容 器 9的底面伸出该液体容器 9, 作为所述定量排液装置的排液口， 所述底部管口 14被可拆卸 地封闭， 通过封闭或者开启所述底部管口 14, 实现停止放水和放水的操作。
所述排液管 1还包括垫片 5,该垫片 5借助超声波工艺或者粘结工艺安装在所述排液管 1 的顶部管口 15, 用于封闭该排液管 1的顶部管口 15。
所述排液管 1还包括胶塞 6, 借助该胶塞 6实现对所述排液管 1的底部管口 14可拆卸的 封闭。
本发明优选实施例， 如图 6和图 8所示， 所述排液管 1的管壁包括下排液管壁 16和上排 液管壁 17。 所述下排液管壁 16的外径大于上排液管壁 17的外径。 所述外套管 2的底部管壁 的内侧能够紧贴在下排液管壁 16 的外侧滑动。 所述液位控制杆 3 的管壁在所述上排液管壁 17的外侧面与外套管 2的管壁内侧面之间滑动。
为防止提拉液位控制杆 3时， 将液位控制杆 3从排液管 1与外套管 2之间拉出， 本发明 优选实施例， 所述液位控制杆 3的管壁包括下控制管壁 36和上控制管壁 37。 所述下控制管 壁 36的内径大于上控制管壁 37的内径。 所述排液管 1的顶部设置有沿径向伸出该排液管 1 管壁的至少一卡钩 18。 该卡钩 18外径大于排液管管壁外径。 所述下控制管壁 36的内侧面紧 贴排液管 1的管壁外侧面在卡钩 18下方滑动。
所述液位控制杆 3还包括拉帽 38, 该拉帽 38罩盖在所述液位控制杆 3的顶部管口， 从 而将所述液位控制杆 3的顶部管口封闭。
为液体容器 9内液体从排液管 1、 外套管 2和液位控制杆 3之间漏出， 本发明优选实施 例在所述排液管 1的全排排液口 10和各内定液位排液口 11的上方和下方都设置有密封圈 8。
所述胶塞 6与密封圈 8起到双重保护作用。 当密封圈 8因长期使用等原因造成失效时， 所述胶塞 6还是可以起到防止液体容器 9内的液体通过所述定量排液装置渗漏的作用。
本发明优选实施例将下方的内定液位排液口设置在液体容器 9的 1/2液位处， 位于上方 的内定液位排液口设置在液体容器 9的 2/3液位处。 所述定量排液装置的初始状态是液位控 制杆 3的凸台在外套管 2的顶部端面上， 但没有滑入滑槽 42内。所述定量排液装置的操作过 程如下：
由初始状态将液位控制杆 3向上拉， 由于有卡钩 18的阻挡， 当拉到最大位移处时， 导流 口位于 2/3液位处的内、 外定液位排液口 11、 21之间。 打开胶塞 6就实现将液体容器 9内的 1/3液体排出。
由初始状态将液位控制杆 3转动至凸台 41滑入滑槽 42内， 下压液位控制杆 3, 令凸台 41滑入定位槽 43内， 从而将导流口 32位于 1/2液位处的内、 外定液位排液口 11、 21之间。 打开胶塞 6实现将液体容器 9内的 1/2液体排出。
由初始状态将液位控制杆 3转动至凸台 41滑入滑槽 42内， 下压液位控制杆 3, 令凸台 41滑入定位槽 43内， 随后转动液位控制杆 3, 使凸台 41不能从定位槽 43滑入滑槽 42内， 从而使液位控制杆 3与外套管 2连接， 向上拉液位控制杆 3, 使外套管 2随液位控制杆 3联 动上移， 从而使全排排液口 10不再被外套管 2近底部管壁覆盖， 排液管 1管壁内空间与液体 容器 9内空间通过全排排液口 10连通。 打开胶塞 6实现将液体容器 9内全部液体排出。
