几年来,水文缆道测流发展很快,越来越显示出它的优越性。但若要充分发挥其作用,则还有一些具体问题需要进一步解决。例如:兴建了电动缆道,如果没有一套控制设备就无法准确定位;水面、河底信号不可靠,就无法测深等等。对此,我们几年来为提高无偏角电动缆道测深和定位的精度,在工作中进行了一些试验研究,取得了一定成果,现介绍如下。一、电机控制无偏角缆道水平来回运行与垂直升降是分别由两个电机带动的。我们采用JZ-Ⅱ型绞车和两台电动机功率各为1.5KW。控制线路如
In recent years, hydrological cable measurement flow developed rapidly, more and more shows its superiority. However, if we want to give full play to its role, there are still some specific problems that need to be further resolved. For example: the construction of electric cableway, without a control device can not be accurately positioned; water, river bottom signal is not reliable, it can not sounding and so on. In this regard, in recent years, we have done some experiments and studies to improve the accuracy of the sounding and positioning of unvulcanized cable lanes and achieved some results. First, the motor control without angle cable horizontal back and forth operation and vertical lift are driven by two motors. We use JZ-Ⅱ winch and two motor power each 1.5KW. Control lines such as
