Description

高性能清水潜水泵 技术领域
本发明涉及一种水泵，特别是一种高性能清水潜水泵。
背景技术
潜水泵是一种泵体和电动机可浸入水中工作的排水机械，其中清水潜水泵是潜水泵中的一种，其适用于清洁水、软化水的循环和增压。
传统清水潜水泵由泵体、潜水电机（包括电缆）、输水管和控制开关四大部分组成，潜水电机位于泵体内，输水管与泵体的输水口连接。其工作如下：开泵前，泵体内必须充满液体；开泵后潜水电机带动叶轮高速旋转，其中的液体随着叶片一起旋转，在离心力的作用下，飞离叶轮向外射出，射出的液体在泵体的扩散室内速度逐渐变慢，压力逐渐增加，然后从连接在输水口上的输水管排出；此时，在叶片中心处由于液体被甩向周围而形成既没有空气又没有液体的真空低压区，液池中的液体在池面大气压的作用下，经吸入口流入泵体内，液体就是这样连续不断地从液池中被抽吸上来又连续不断地从输水管流出。
在具体使用中上述传统清水潜水泵存在以下不足之处： 1 ）、当一处深井内的液体将要被抽干，没有持续的液体进入泵体时，传统清水潜水泵的输水管内的残留液体会倒流进入泵体，然后从泵体的吸入口流出，致使无法将深井内的液态抽干； 2 ）、传统清水潜水泵摆放在深井底部时，其泵体底面的吸入口与深井底表面之间的垂直距离无法调节，也就是说泵体底面的吸入口的进水速度无法实现调节，操作性差； 3 ）、传统清水潜水泵的控制开关部分无法通过泵体内有无液体来实现潜水电机开与关的控制，控制智能化差。
 技术问题
本发明的目的是为了解决上述现有技术的不足而提供一种能有效避免当深井内的液体将要被抽干时输水管内的残留液体倒流入泵体，同时泵体底面吸入口的吸水速率可以实现调节以及结合有自动水位开关的高性能清水潜水泵。
技术解决方案
为了实现上述目的，本发明所设计的高性能清水潜水泵，包括手柄、泵体以及可拆卸式连接在泵体出水口的输出管接头，手柄铰接在泵体的顶端，在输出管接头的泵体出水口连接端内壁上铰接有能够将该泵体出水口连接端封闭的单向阀，在泵体的一侧外表面上连接有能够将该单向阀顶开的按钮，所述泵体内活动连接有可作上下往复运动的支撑脚连杆，并且该支撑脚连杆往下运动时，其底端的支撑脚部分能超出泵体底面，所述手柄下方设有传动偏心块与上述支撑脚连杆的顶部传动配合，所述泵体上还设有通过水泵工作的水位高低来控制水泵开启或关闭的自动控制开关组件。
作为优选，所述自动控制开关组件是指所述泵体内还设有条形导流腔，在该条形导流腔的两内侧壁位置上均固定有一条第一轨道，在上述两条第一轨道上共同配合有能够依着两条第一轨道作上下往复运动的水泵开启开关和水泵关闭开关，并且水泵开启开关的位置不能低于水泵关闭开关的位置，在上述条形导流腔的内壁上还固定有两条高低不一的第二轨道，其中位置相对较高的一条第二轨道上滑动连接有与水泵开启开关配合的浮子或带磁铁的浮子，在位置相对较低的一条第二轨道上滑动连接有与水泵关闭开关配合的浮子或带磁铁的浮子。该优选方案中自动控制开关组件的结构简单，工作稳定性高。
为了方便支撑脚连杆在泵体上的拆卸、组装，本发明中所提供高性能清水潜水泵的支撑脚连杆上至少开设有两个腰形孔，在上述腰形孔内贯穿有紧固件，并且紧固件的端头固定在泵体的内壁上。
 有益效果
本发明得到的高性能清水潜水泵，其结构中在输出管接头的泵体出水口连接端内壁上铰接有能够将该泵体出水口连接端封闭的单向阀，在工作中液体在压差的作用下持续进入泵体，待泵体内充满液体后，上述单向阀会被液体顶开从而完成清水潜水泵输水，当深井内液体将要被抽干，没有持续的液体进入泵体致使水的顶开力消失时，上述单向阀就会在自重作用下将输出管接头的泵体出水口连接端封闭，从而避免输水管内残留液体倒流进入泵体，然后从泵体的吸入口流出，还有当清水潜水泵从深井中取出后，为了能方便排放输水管内的残留液体，在泵体的一侧外表面上连接有能够将该单向阀顶开的按钮；同时本发明所提供高性能清水潜水泵的另一侧外表面上活动连接有可作上下往复运动的支撑脚连杆，在清水潜水泵摆放在深井底部工作时，其泵体底面的吸入口与深井底表面之间的垂直距离可以实现调节，也就是说泵体底面的吸入口的进水速度可以实现调节；最后水位开关的设置能提升本发明的操作智能化。
