Abstract

The invention discloses a laser range finder for water gauge measurement and a using method. A measuring pipe of the range finder is vertically inserted into a water body, the bottom of the measuringpipe is open, liquid can flow into an inner cavity of the measuring pipe, a laser displacement sensor is installed at the top of the measuring pipe, a baffle is installed on the pipe wall of the lowerportion of the measuring pipe, and a one-way valve is arranged on the baffle; a floatable reflecting plate is arranged in an inner cavity of the measuring tube and is positioned between the baffle plate and the laser displacement sensor; a vent hole is formed in the pipe wall of the upper part of the measuring pipe, is positioned between the reflecting plate and the laser displacement sensor andis positioned above the liquid level during measurement; one end of the cable is connected with the laser displacement sensor and the other end of the cable is connected with the display; and scales are marked on an outer surface of the cable. The laser range finder can achieve millimeter-level high-precision measurement of the water level, is simple in use method, and has the advantages of beinghigh in safety, wide in application range and small in manual observation error.

Description

technical field [0001] The invention belongs to the technical field of water gauge measurement, in particular to a laser rangefinder for water gauge measurement and a use method. 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 ...
