Description

一种用于燃气和水的计量表
(一)        技术领域
    本发明涉及一种计量表,特别涉及一种用于燃气和水的计量表。
(二)        背景技术
    目前技术下,燃气、水、电表等都具有直读远传的功能,不再需要抄表员挨家挨户人工抄表,只需安装在表上的传感器即可远传输入计算机。通常用于计量气、液、电等流量的计量表,其工作原理是通过气、液、电介质通过仪表内的检测流量装置,检测流量装置带动传动装置,再由传动装置带动读数圆盘转动,当读数盘上设置字码时,通过读数圆盘上的转动量由字码反映出来。但是,由于水表或燃气表安装条件的限制,很多发射管盘不能做到360度的圆周,再者,需要的接收管个数太多,接受管单价又较贵,造成极大地浪费。
(三)        发明内容
    本发明为了弥补现有技术的不足,提供了一种成本低、制作安装简单、读数准确度高、使用寿命长的用于燃气和水的计量表。
本发明是通过如下技术方案实现的: 
一种用于燃气和水的计量表,包括壳体,壳体下部一侧安装有支架,其特征是:所述支架上安装有挠形板,挠形板上安装有若干组发射管,挠形板下部安装有空心轴,空心轴内设有印制板,印制板上设有若干个接收管,每个接收管分别与对应一列发射管,每个接收管外分别对应套设有字轮,字轮两侧分别设有透明凹槽,透明凹槽内放置黑条。
所述发射管分别由一列三个的和一列两个的组成一组,共有四组。
所述发射管4还可以组成3~8组。
所述发射管也可以由一列五个组成一组。
本发明的有益效果是:可适用于任何空间的燃气表和水表的安装,成本低、制作安装简单、读数准确度高、使用寿命长,为燃气和水使用量测量做出来巨大贡献。 
(四)        附图说明
下面结合附图对本发明作进一步的说明。
附图1为本发明的结构示意图;
附图2为本发明的横截面结构示意图;
图中,1壳体,2支架,3挠形板,4发射管,5空心轴,6印制板,7接收管,8字轮,9透明凹槽,10黑条。
(五)        具体实施方式
附图为本发明的一种具体实施例。该实施例包括壳体1,壳体1下部一侧安装有支架2,支架2上安装有挠形板3,挠形板3上安装有若干组发射管4,挠形板3下部安装有空心轴5,空心轴5内设有印制板6,印制板6上设有若干个接收管7,每个接收管7分别与对应一列发射管4,每个接收管7外分别对应套设有字轮8,字轮8两侧分别设有透明凹槽9,透明凹槽9内放置黑条10。发射管4分别由一列三个的和一列两个的组成一组,共有四组。所述发射管4还可以组成3~8组。发射管4也可以由一列五个组成一组。
采用本发明的一种用于燃气和水的计量表,挠形板3可适用于条件不允许使用180°以上圆弧的发射管4的安装,燃气或水在使用时会流动,流动带动字轮8旋转,每组发射管4发射至与其对应的接收管7,发射信号时经过透明凹槽9,透明凹槽9内放置黑条10,转动过一定角度后,发射管4发射的信号经过透明凹槽9到接收管7时,可能会通过也可能会被黑条10阻挡,这样根据每个发射管4发射信号时能否被接收管7接收到得到一个代码,五个发射管4分别发射得来的代码便是这个数位上的数字,每组代表一个数位,即可读取其任何时刻显示的数值。这里发射管4发射时,接收管7能否接受到所得出的代码,五个代码所读取的数字的原理省略。这样,发射管4安装于一小角度的弧形板即挠形板3上,避免了条件有限时不能安装180°以上圆弧形发射管4的问题。另外,每组发射管4对应两个接收管7,只需8个接收管7,现有技术是总共需要40个接收管7和发射管4,每个接收管7是1.3元,每个表就节省了40多元,成本大大降低。
