Description

一种防滴漏智能水表
本发明属自来水防滴漏智能水表技术领域。
目前自来水公司的供水模式,一般是通过大水表再到小水表。大水表多是安装在一个单位或社区集体单位里,小水表则直接安装在市民用户家中。目前市售产品小水表的流量小于一定值(如12升/小时)时可不计数,这样用户家中的小水表只要不超过这个水流量则小水表可不计数。若是多家用户同时用这种小流量在每家的小水表上显示出一定数值,一般情况大水表所显示数值总和要比小水表显示数据累加值多10~30%以上,这样造成大小水表计数的差额。由于存在这个差额往往造成一些不必要的经济矛盾和纠纷。
本发明的目的,就是要解决小水表滴漏不计数的技术关键问题。
本发明的技术方案是这样实现的,结合附图进行说明。图1为本发明带有阀和发讯水表的产品结构正视图,图2为本发明不带有阀和发讯水表的产品结构正视图,图3为本发明的套筒立体结构示意图,图4为本发明的电原理结构示意图。由单片机控制处理的一种防滴漏智能水表,其特征在于,如图1所示,由密封板4、大出水口5、信号传输部分6、压力弹簧7、传动杆8、活塞9、滴漏水孔10、上压盖13、密封圈14、外壳15、套筒16等部分组成防滴漏水表,图1中的箭头为水流方向,防滴漏水表左端接有阀,阀分为阀头部分2和阀体部分3,在阀头部分2的左面为进水口1,阀头部分2和阀体部分3可由多种结构形式,如电磁阀、电机阀、电动阀等,上述多种结构形式的阀均为已知技术不再赘述。在防滴漏水表的右端接有发讯水表11,发讯水表11为已知技术,不再赘述,在发讯水表11的右端为出水口12。一种防滴漏智能水表,其特征在于,如图2所示,上压盖13固定在外壳15的上面,套筒16固定在外壳15的里面,大出水口5在套筒16的上半部分,17为进水口,活塞9固定在传动杆8的下端,传动杆8装在套筒16的内部,压力弹簧7套在传动杆8上,滴漏水孔10开在套筒16的下半部分,18为出水口,密封圈14在传动杆8的上端,密封板4固定在上压盖13的上面,在密封板4的上面接有信号传输部分6,信号传输部分6可采用多种传输方式,如压力传感器、电位器、干簧管、光电管、霍尔元件等。一种防滴漏智能水表,其特征在于,见图3,大出水口5开在套筒16的上半部分,它开有多个大出水口,形状可为长方口或长圆口,滴漏水孔10开在套筒16的下半部分,它开有多个圆形小孔。一种防滴漏智能水表,其特征在于,如图4所示,单片机U1和信号处理器U8相连,信号处理器U8由电阻R8、R9、电容C3组成,并和信号放大器U9相连,信号放大器U9由电阻R0、R1、R2和U4:A组成。信号放大器U9和发讯水表11(图1)U6相连,单片机U1通过电阻R9和信号传输部分6(见图1)U7相连,单片机U1和存储器U3相连,并和液晶显示器U2相连,电源U5为各部分提供工作电压。本发明的工作原理及工作过程,当水从进水口1流入时,由阀体部分3的作用使阀头部分2打开阀门,水流沿图1中箭头所指方向进入到防滴漏水表内,由水流所产生的压力推动活塞9上移,这时套筒16的防滴漏水孔有水流流出,虽然有较小的水流量流动,也能使活塞9上移,传动杆8也随之上移,传动杆8的上移通过信号传输部分6把水流量信号变为电信号,把此信号输送到单片机U1中,通过单片机U1的处理和控制,使其显示出水流量。当水流较大时露出的防滴漏水孔越多,所显示的水流量数据越大。当水流量越大,活塞9上移越大,水流量大到使大出水口5露出时,这时信号传输部分6不再起作用,由发讯水表11通过出水口12,传出水流量信号,送到单片机U1通过处理和控制使其显示水流量。
本发明的突出特点,当水流量小于12升/时,即水龙头滴漏时,防滴漏智能水表仍可计数计量,这样可防止因水龙头滴漏所造成的水流损失,也可减少大小水表之间的差额计量,保证市民用户交水费的合理性。本发明具有由滴漏计数到大水量计数可自行转换的功能,并有自动控制、自动计数、显示存储等功能。它还具有灵敏度高、可靠性高、重复性好、安装调试方便等优点,便于推广应用。它可广泛地应用于自来水供水系统,为自来水公司直接对市民用户用水提供了便利条件。
实施例:按照图1、图2的要求,将滴漏智能水表的硬件制作完成后,再按照图4的要求进行焊接。单片机U1的1脚接信号处理器U8中的R8,并接存储器U3的8脚,发讯水表11通过传感器U6的3脚、电源U5的2脚、信号放大器U9中的U4:A的4脚和液晶显示器U2的2脚相连,单片机U1的2脚和液晶显示器U2的3脚相连,U1的3脚和信号放大器U9中的U4:A的1脚,并通过电阻R1和2脚相连,U1的4脚和液晶显示器U2的1脚相连。U1的5脚通过R9和传感器U7的2脚相连,U1的6脚和存储器U3的6脚相连,U1的7脚和存储器U3的5脚相连,其8脚和电源U5的1脚相连并和C3相连,并和信号传输部分6的传感器U7的1脚相连。信号放大器U9中的U4:A的3脚通过电阻R0和U6的2脚相连,U6的1脚、U4:A的11脚、U5的1脚、U2的4脚、U3的1、2、3、4、7脚均接地。按照上述连线连接后,通过调试即可达到使用效果。
