Abstract

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.

Description

technical field [0001] The invention relates to the field of water gauge measuring tools, in particular to a laser measuring tube for water gauge measurement. Background technique [0002] Water gauge weight measurement is a very important weight measurement method for shipping bulk cargo. However, due to the influence of factors such as actual personnel observation errors, hull trim and external waves, and the lack of uniform observation standards, the water gauge observation results The accuracy of the water gauge has always been controversial, which has increased the difficulty of evaluating the ability of the water gauge to measure weight. Among them, the controversial measurement link is water gauge observation. In order to reduce the difficulty of water gauge observation, many new observation methods have been proposed one after another, but all of them have the problem of subjective judgment. It is internationally recognized that the accuracy of water gauge weight m...
