Description

水管微漏监控装置及其微漏监控方法 技术领域
本发明涉及生活用具领域，具体涉及一种对水管微漏或滴漏进行漏水监控的装置及其方法。
背景技术
目前国内外的节水装置或系统种类繁多，广泛应用于农业灌溉、工业生产、家庭用水等，大到农业的灌溉系统，小到家居用的抽水马桶，无处不体现人们的节水思想。目前基于家庭节水的装置的种类比较多，比如节水马桶、节水水龙头、节水洗衣机、节水控制系统等。但针对水龙未关紧滴漏水及水龙头忘记关水而造成水浪费的问题，没有专门的解决方案。一个不关紧的水龙头，一个月可以流掉1至6立方米水；一个漏水的马桶，一个月要流掉3至25立方米水；一个城市如果有60万个水龙头关不紧、20万个马桶漏水，一年可损失上亿立方米的水。因此，在日常生活中节约用水是很有必要的。同时，关于专利号为ZL201220296642.7一种智能水管微漏监控装置，其是针对微流水进行监控的，通过水流速度来实现监控的，但是就现在的技术来说，微量的漏水其水流速度很难检测，或者该检测设备需要高精度高成本的先进设备，这样的话就大大的增加了成本，不适于普通家庭日常需求，且在水管振动时，其也是会产生微量的水流运动，这样的话，该技术是完全会导致误判而进行关闭水闸的情况，这样也会给使用带来不便甚至安全隐患。且上述的一种智能水管微漏监控装置，一种家庭防漏水方法及智能水表需要专门的水表进行辅助运行，而水表是通过专门的机构安装的，其修改水表结构较难，不利于普及或在无形中增加了成本。
技术问题
针对现有技术存在的不足，本发明的目的在于提供一种准确性强、监控功能全面且成本低的水管微漏监控装置及其微漏监控方法。
问题的解决方案
技术解决方案
为实现上述目的，本发明提供了如下技术方案：一种水管微漏监控装置，包括设置有进水口(501)和出水口(502)的管道，所述的管道内设置有叶轮(100)和电磁阀(200)，在叶轮(100)靠近进水口(501)的一端设置有流量扩大装置，管道外设置有控制电磁阀(200)开启或关闭的控制器(300)，叶轮(100)上设置有感应叶轮(100)旋转状态的感应器，且所述的感应器和电磁阀(200)分别与控制器(300)连接。
对上述技术方案做进一步的设计：所述的流量扩大装置为一个具有额定压力差的单向阀(400)，且单向阀(400)上开设有细孔(401)，使经过细孔(401)上的水能够喷射到叶轮(100)上并使叶轮(100)旋转，所述的控制器(300)内包括用于具有额定时间并对叶轮(100)的旋转进行计时的叶轮(100)旋转计时模块、用于对叶轮(100)旋转计时模块的计时值进行清零的叶轮(100)计时清零模块、用于关闭电磁阀(200)的电磁阀(200)控制模块。
对上述技术方案做进一步的设计：所述的控制器(300)设置有对叶轮(100)旋转计时模块的额定计时进行输入的额定时间输入模块。
一种适用上述水管微漏监控装置的水管微漏监控方法，其步骤如下：
步骤1：当用户用水时，水管(500)内的水流进行流通，水流经过叶轮(100)使叶轮(100)旋转，此时，叶轮(100)计时模块通过感应器对叶轮(100)的旋转进行计时，当叶轮(100)旋转计时模块超过额定时间时则判断漏水，并关闭电磁阀(200)；
步骤2：当用户停止用水时，如果处于微漏状态，则通过流量扩大装置使微漏的水流扩大并使叶轮(100)旋转，当叶轮(100)旋转计时模块超过额定时间时则判断漏水，并关闭电磁阀(200)；
步骤3：当微漏时间未到达额定时间并解决了微漏情况，则通过叶轮(100)旋转计时清零模块对叶轮(100)旋转计时模块进行清零。
对上述的技术方案做进一步的设计：当流量扩大装置为一个有细孔(401)并具有额定压力差的单向阀(400)，其流量扩大方法为：当微漏时，水管(500)的进水口(501)的压力大于出水口(502)，使单向阀(400)的两侧产生压力差，预先设计单向阀(400)的额定压力差，使额定压力差大于微漏时的压力差，此时单向阀(400)还处于关闭状态，而单向阀(400)上的细孔(401)由于水管(500)内的压力差使水流通过细孔(401)，由于压力差使其水流的速度增大而喷射至叶轮(100)，并使叶轮(10 0)旋转，进而到达扩大水流的效果。

以下将通过具体实施例来对本发明的改造结构进行详细的说明。
一种水管的微漏监控方法，其步骤如下：
步骤1：当用户用水时，水管500内的水流进行流通，水流经过叶轮100使叶轮100旋转，此时，叶轮100计时模块通过感应器对叶轮100的旋转进行计时，当叶轮100旋转计时模块超过额定时间时则判断漏水，并关闭电磁阀200；
步骤2：当用户停止用水时，如果处于微漏或滴漏状态，则通过流量扩大装置使微漏或滴漏的水流扩大并使叶轮100旋转，当叶轮100旋转计时模块超过额定时间时则判断漏水，并关闭电磁阀200；
步骤3：当微漏或滴漏时间未到达额定时间并解决了微漏情况，则通过叶轮100旋转计时清零模块对叶轮100旋转计时模块进行清零。
当流量扩大装置为一个有细孔401并具有额定压力差的单向阀400，其流量扩大方法为：当微漏或滴漏时，水管500的进水口501的压力大于出水口502，使单向阀400的两侧产生压力差，预先设计单向阀400的额定压力差，使额定压力差大于微漏时单向阀400两侧的压力差，此时单向阀400还处于关闭状态，而单向阀400上的细孔401由于水管500内的压力差使水流通过细孔401，由于压力差使其水流的速度增大而喷射至叶轮100，并使叶轮100旋转，进而到达扩大水流的效果。此处的滴漏指水龙头为关紧导致的自然水外漏的现象。
参考图1至6，一种水管500微漏监控装置，包括设置有进水口501和出水口502的管道，所述的管道内设置有叶轮100和电磁阀200，在叶轮100靠近进水口501的一端设置有流量扩大装置，管道外设置有控制电磁阀200开启或关闭的控制器300，叶轮100上设置有感应叶轮100旋转状态的感应器，且所述的感应器和电磁阀200分别与控制器300连接，所述的控制器300内包括用于具有额定时间并对叶轮100的旋转进行计时的叶轮100旋转计时模块、用于对叶轮100旋转计时模块的计时值进行清零的叶轮100计时清零模块、用于关闭电磁阀200的电磁阀200控制模块、对叶轮100旋转计时模块的额定计时进行输入的额定时间输入模块。其中 ，额定计时为叶轮100旋转的最长时间，通过控制面板可以直接调整。
上述的流量扩大装置其结构具体如下：
实施例一：参考图1和图2，所述的流量扩大装置为一个具有额定压力差的单向阀400，且额定压力差大于微漏时单向阀400两侧的压力差，在单向阀400上开设有多个细孔401，由于压力差使水流经过细孔401，由于细孔401的孔径远远小于水管500的直径，在压力差相同时，细孔401的水流大于水管500的水流，进而使水流通过细孔401喷射到叶轮100上并使叶轮100旋转，进而到达水量扩大效果。
实施例二：参考图3和图4，在水管500上加上一个止回阀，且在第一止回阀900相对进水口501的前端设置有一个细水管500，并使细水管500一端与叶轮100的叶片靠近，另一端设置有第二止回阀，且第一止回阀900的额定压力差大于第一止回阀900的压力差。此时当水管500进行微漏时，由于第二止回阀的额定压力差小于第一止回阀900，此时第一止回阀900打开，且由于细管的孔径小于水管500，故细管的水流速大于水管500，并通过压力喷射至叶轮100上使其旋转。
上述的单向阀400、第一止回阀900和第二止回阀的其结构可以为如图5上所示，包括挡板和堵片，在单向阀400的堵片上开细孔401，而第一止回阀900和第二止回阀的堵片上不设置细孔401，而挡板与堵片之间通过拉力弹簧700进行封堵，同时也可以参考图6通过推力弹簧800实现封堵，当然也可以用普通的单向阀400实现。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的监控范围之内。
