A mechanical flowmeter is generally composed of a liquid wheel assembly, a counter, and a display code disc. The liquid wheel assembly includes a liquid wheel and a worm gear transmission mechanism. When water passes through the flow in the pipeline to drive the liquid wheel to rotate, the worm gear mechanism will The vertical rotation is converted into horizontal rotation and transmitted to the transmission mechanism of the counter. The transmission mechanism changes the speed and finally transmits it to the counter dial for display. In the process of worm gear and gear transmission, because the worm gear must cooperate with the liquid wheel, the worm gear is immersed in the fluid for a long time. When there are many impurities in the fluid or the sediment content is large, the sediment may block the worm gear. In the screw mechanism, the screw mechanism is stuck and cannot operate normally, resulting in inaccurate or non-counting.
因此，如何解决液轮组件中的蜗轮蜗杆被卡死造成的流量计不能正常运转，继而造成流量计计数不准或不计数的问题是本领域技术人员亟待解决的技术问题。Therefore, how to solve the problem that the flowmeter cannot operate normally due to the stuck worm gear in the liquid wheel assembly, and then cause the flowmeter to count inaccurately or not to count is a technical problem urgently to be solved by those skilled in the art.

在本实施例中，液轮片201包括第一液轮片20101、第二液轮片20102和第三液轮片20103，第一液轮片20101和第二液轮片20102上均设置有永磁体5，第三液轮片20103上设置有无磁性配重体6。永磁体5起计量的作用，而无磁性配重体6是为了配重而设置的。且在本实施例中，第一液轮片20101、第二液轮片20102和第三液轮片20103均布在液轮2上。这样便于液轮2旋转的转速的稳定性。In this embodiment, the liquid wheel 201 includes a first liquid wheel 20101, a second liquid wheel 20102 and a third liquid wheel 20103, and the first liquid wheel 20101 and the second liquid wheel 20102 are provided with permanent The magnet 5 and the third liquid wheel piece 20103 are provided with a non-magnetic counterweight 6 . The permanent magnet 5 plays the role of metering, and the non-magnetic counterweight body 6 is provided for counterweight. And in this embodiment, the first liquid wheel 20101 , the second liquid wheel 20102 and the third liquid wheel 20103 are evenly distributed on the liquid wheel 2 . This facilitates the stability of the rotation speed of the liquid wheel 2 .
需要说明的是，无磁性配重体6是指没有磁性，不会产生磁力线的磁体，将其安装到第三液轮片20103上仅为了配重的目的。It should be noted that the non-magnetic counterweight body 6 refers to a magnet that has no magnetism and does not generate magnetic force lines, and it is installed on the third liquid wheel piece 20103 only for the purpose of counterweight.
在本实施例中，液轮片201还包括第四液轮片20104、第五液轮片20105和第六液轮片20106，其中，第四液轮片20104位于第一液轮片20101和第二液轮片20102之间，第五液轮片20105位于第二液轮片20102和第三液轮片20103之间，第六液轮片20106位于第一液轮片20101和第三液轮片20103之间。且第四液轮片20104、第五液轮片20105和第六液轮片20106均布在液轮2上。In this embodiment, the liquid wheel 201 further includes a fourth liquid wheel 20104, a fifth liquid wheel 20105 and a sixth liquid wheel 20106, wherein the fourth liquid wheel 20104 is located between the first liquid wheel 20101 and the sixth liquid wheel Between the two liquid wheels 20102, the fifth liquid wheel 20105 is located between the second liquid wheel 20102 and the third liquid wheel 20103, and the sixth liquid wheel 20106 is located between the first liquid wheel 20101 and the third liquid wheel Between 20103. And the fourth liquid wheel plate 20104, the fifth liquid wheel plate 20105 and the sixth liquid wheel plate 20106 are evenly distributed on the liquid wheel 2.
当第二液轮片20102和第三液轮片20103分别位于2个线圈4的磁力线范围时，第二液轮片20102上的永磁体5划过线圈4，对应的线圈4会切割永磁体5的磁力线，并产生出感应电动势，通过接线端子将感应电动势的变化输出给辅助设备来记录显示。When the second liquid wheel 20102 and the third liquid wheel 20103 are respectively located in the range of the magnetic force lines of the two coils 4, the permanent magnet 5 on the second liquid wheel 20102 passes through the coil 4, and the corresponding coil 4 will cut the permanent magnet 5 The magnetic lines of force are generated, and the induced electromotive force is generated, and the change of the induced electromotive force is output to the auxiliary equipment through the terminal for recording and displaying.
当第五液轮片20105和第六液轮片20106分别位于2个线圈4的磁力线范围时，此时，由于第五液轮片20105和第六液轮片20106上没有永磁体5，因此，线圈4无任何感应电动势，通过接线端子将零感应电动势的变化输出给辅助设备，辅助设备将感应电动势的信号转换成流量并显示。When the fifth liquid wheel 20105 and the sixth liquid wheel 20106 are located in the range of the magnetic force lines of the two coils 4, at this time, since there is no permanent magnet 5 on the fifth liquid wheel 20105 and the sixth liquid wheel 20106, therefore, The coil 4 has no induced electromotive force, and the change of the zero induced electromotive force is output to the auxiliary equipment through the terminal, and the auxiliary equipment converts the signal of the induced electromotive force into a flow rate and displays it.
当第一液轮片20101和第三液轮片20103分别位于2个线圈4的磁力线范围时，此时对应的线圈4会切割第一液轮片20101上的永磁体5的磁力线，产生感应电动势，通过接线端子将感应电动势的变化输出给辅助设备，辅助设备将感应电动势的信号转换成流量并显示。When the first liquid wheel piece 20101 and the third liquid wheel piece 20103 are respectively located in the range of the magnetic force lines of the two coils 4, the corresponding coil 4 will cut the magnetic force lines of the permanent magnet 5 on the first liquid wheel piece 20101 to generate an induced electromotive force , output the change of the induced electromotive force to the auxiliary equipment through the terminal, and the auxiliary equipment converts the signal of the induced electromotive force into a flow rate and displays it.
当第一液轮片20101和第二液轮片20102分别位于2个线圈4的磁力线范围时，由于第一液轮片20101和第二液轮片20102上均设置有永磁体5，因此，2个永磁体5分别与2个线圈4交叉，产生两个感应电动势，通过接线端子将感应电动势的变化输出给辅助设备，辅助设备将感应电动势的信号转换成流量并显示。When the first liquid wheel 20101 and the second liquid wheel 20102 are respectively located in the range of the magnetic force lines of the two coils 4, since the first liquid wheel 20101 and the second liquid wheel 20102 are provided with permanent magnets 5, therefore, 2 Two permanent magnets 5 respectively intersect with two coils 4 to generate two induced electromotive forces, and output the changes of the induced electromotive forces to the auxiliary equipment through the terminal, and the auxiliary equipment converts the signal of the induced electromotive force into a flow rate and displays it.
如图8所示，为采集时序图，表示一个液轮转动一圈的时序，当液轮转动后，永磁体4切割两个线圈204(设两个线圈204分别为A线圈和B线圈)产生电动势后，经过放大滤波后形成的波形图，其中，图中A表示A线圈产生的感应电动势，图中B表示B线圈产生的感应电动势。由于两线圈204放置位置关系，首先A线圈产生电动势输出为高电平(见波形图a区)，当液轮继续转动，B线圈产生电动势输出为高电平，这时A线圈继续输出高电平(见波形图b区)，当液轮202继续转动,A线圈远离永磁体4后，感应电动势减少通过放大滤波比较后导致输出为低(见波形图c区)，B线圈远离永磁体4后，感应电动势减少通过放大滤波比较后导致输出为低(见波形图d区)，当另一磁铁经过线圈时，也会产生e、f、g区的波形，这时微控制单元就此判定为液轮202转动了一周，根据管道直径和液轮的周长计算液轮转动一周流过管道的水量来。As shown in Fig. 8, it is a collection timing diagram, which shows the timing of a liquid wheel rotating one circle. After the liquid wheel rotates, the permanent magnet 4 cuts two coils 204 (the two coils 204 are respectively A coil and B coil) to generate After the electromotive force, the waveform diagram formed after amplification and filtering, where A in the figure represents the induced electromotive force generated by the A coil, and B in the figure represents the induced electromotive force generated by the B coil. Due to the positional relationship between the two coils 204, firstly, coil A generates electromotive force output at high level (see area a in the waveform diagram), when the liquid wheel continues to rotate, coil B generates electromotive force output at high level, and coil A continues to output high level at this time Flat (see waveform diagram area b), when the liquid wheel 202 continues to rotate, A coil is far away from the permanent magnet 4, the induced electromotive force is reduced and the output is low after amplification and filtering comparison (see waveform diagram c area), B coil is far away from the permanent magnet 4 Finally, the induced electromotive force is reduced and the output is low after the amplification and filtering comparison (see the d area of the waveform diagram). When another magnet passes through the coil, the waveforms of the e, f, and g areas will also be generated. At this time, the micro control unit judges as The liquid wheel 202 has rotated one revolution, and the amount of water flowing through the pipeline is calculated according to the pipe diameter and the circumference of the liquid wheel.
