The invention discloses a laser measuring tube for measuring a water gauge. The laser measuring tube comprises a measuring tube (3) vertically inserted into a water body, an opening is formed in the bottom of the measuring tube (3) so that liquid can flow into an inner cavity of the measuring tube, a laser displacement sensor (1) is installed at the top of the measuring tube (3), a baffle (4) is installed on the tube wall of the lower portion of the measuring tube (3), and a one-way valve (5) is arranged on the baffle (4). A floatable reflecting plate (6) is arranged in an inner cavity of themeasuring tube (3) and is positioned between the baffle plate (4) and the laser displacement sensor (3); a vent hole (2) is formed in the pipe wall of the measuring pipe (3), and the vent hole (3) islocated between the reflecting plate (6) and the laser displacement sensor (1) and located above the liquid level in the measuring process. The laser measuring tube can achieve millimeter-level high-precision measurement of the water level, and has the characteristics of simplicity in operation, high safety and small manual observation error.

    本发明公开了一种用于水尺测量的激光测量管,该激光测量管包括垂直插入水体中的测量管(3),测量管(3)的底部设置开口,以供液体流入测量管内腔,测量管(3)的顶部安装有激光位移传感器(1),测量管(3)下部的管壁上安装有挡板(4),挡板(4)上设有单向阀(5);测量管(3)的内腔中设有可漂浮的反射板(6),反射板(6)位于挡板(4)与激光位移传感器(3)之间;测量管(3)的管壁上设有通气孔(2),通气孔(3)位于反射板(6)与激光位移传感器(1)之间,且在测量时位于液面上方。本发明可实现水位毫米级高精度测量,具有操作简单、安全性高和人工观测误差小的特点。
