JLC-I 型积时式缆道采样器是重庆水文仪器厂为测站实现测流取沙缆道化而设计生产的一种水文测验仪器。该仪器工作效率高,调压性能好,操作简便。但在使用中除受地质、水质和化学电位影响外,仪器本身800H_2交流讯号也会发生干扰,还有外来电讯号的干扰,致使仪器口门经常自动开启,无法正常工作。为此,我站对该仪器作了适当改进,成为有线和无线两种控制。改装后不影响原仪器的特性和使用范围,经两年来的比测和使用,测速、测深
JLC-I type plot-type cableway sampler is a hydrological test instrument designed and manufactured by Chongqing Hydrological Instrument Factory for the purpose of measuring runoff and sand removal from the station. The high efficiency of the instrument, the regulator performance, easy to operate. However, in addition to the influence of geology, water quality and chemical potentials, the interference of the 800H_2 AC signal of the instrument itself and the interference of the external signal cause the instrument door to open frequently and can not work normally. To this end, I have made appropriate improvements to the instrument, a wired and wireless two kinds of control. Modified after the original instrument does not affect the characteristics and scope of use, after two years of comparison and use, speed, depth
