Following type laser water level gauge

Abstract

The invention provides a following type laser water level gauge which comprises a water level gauge body, the water level gauge body comprises a limiting pipe, a reflection buoy, a first laser range finder and a second laser range finder, the limiting pipe is installed on the inner wall of a dam through a fixing rod at the rear end, and a top cover is arranged at the top of the limiting pipe. A first laser range finder is installed at the bottom end of the top cover, an inserting column is arranged at the bottom end of a limiting pipe, a lifting channel is formed in the limiting pipe, a floating plate is installed in the lifting channel, one side of the floating plate is connected with a lifting rod through a supporting rod, and a reflection buoy is arranged at the top of the lifting rod. One side of the reflection buoy is provided with a supporting plate, the top of the supporting plate is provided with a second laser range finder, according to the following type laser water level gauge, the reflection buoy can be effectively prevented from inclining or deviating, fluctuation of water flow is buffered and filtered, measured data are more accurate and stable, and the measuring precision is higher.

Description

technical field [0001] The invention relates to the technical field of water level measurement, in particular to a follow-up laser water level gauge. Background technique [0002] There are many methods in water level measurement, and the following laser water level gauge has been widely used because of its high precision and wide application range. [0003] The laser water level gauge needs to be used with a reflective buoy. During installation, it is necessary to set the attached table at the bottom of the laser rangefinder, but the buoy will fluctuate with the liquid level, making it difficult to maintain a level. After the laser is reflected on the surface of the reflective buoy, The fluctuation range will also be relatively large, especially when the buoy is tilted, it will cause a large error in the measured water level height. Real liquid level data. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the object of the present invention...
