Transparent double-measurement-system static force level gauge and use method thereof

Abstract

The invention relates to a transparent double-measurement-system static force level gauge and a use method thereof. The transparent double-measurement system static force level gauge is characterized in that a surface measurement ruler is arranged on the outer wall of a transparent liquid storage barrel, an air pressure balance hole is formed above the transparent liquid storage barrel and can be externally connected with an air pressure balance valve, a liquid inlet is formed below the transparent liquid storage barrel and can be externally connected with a liquid inflow valve, and a liquid communicating pipe is arranged at the bottom of the transparent liquid storage barrel; a magnetostrictive liquid level meter is arranged in the transparent liquid storage barrel and connected with a circuit module arranged on the transparent liquid storage barrel, and a vertical displacement indicator lamp is connected with the circuit module. When a measurement point is displaced vertically, a pressure difference exists between a reference point and the measurement point, the magnetostrictive liquid level meter in the static force level gauge is driven to extend and shrink, and the position of the liquid level where a floater is located can be precisely determined by measuring the time difference between pulse currents and torsional waves. In addition, double-system measurement is achieved through reading of the surface measurement ruler in the static force level gauge.

Description

technical field [0001] The invention relates to a transparent double measuring system static level and a using method thereof. Background technique [0002] In engineering construction and completed buildings, due to uneven foundation or differences in building loads, vertical vertical displacements will occur. Vertical vertical displacement observation is a very basic monitoring parameter in engineering construction. Some vertical vertical displacements It is within the allowable range, and some may cause defects in project quality or even catastrophic accidents, and it is especially important for the vertical displacement observation of completed projects, such as the vertical displacement of dangerous houses, subways, bridges, dams, etc. The vertical displacement will be a huge accident, causing heavy casualties and other social hazards. Therefore, it is extremely necessary to manage the project based on the monitoring data. [0003] In recent years, with more and more ...

AI Technical Summary

Problems solved by technology

Vertical vertical displacement is a very important parameter for engineering health monitoring. Compared with the traditional observation method of manual leveling, most of the current monitoring methods are relatively backward. As the monitoring requirements of structures become higher and higher, real-time online Monitoring has become a trend in health monitoring. Traditional static levels use liquid storage tanks, which cause the liquid surface to flow with the vertical displacement of the monitoring point, thereby driving the float of the buoy to drive the measuring rod. Due to structural connections, many It is connected to the measuring rod, and there is a certain friction between the measuring rod and the pipe wall. It must be reflected by a certain amount of vertical displacement. The zero jump of the data is not accurate. Secondly, due to the working principle, the volume must be huge. Very unfavorable for on-site operation and installation
