technical field

The invention relates to a calibration device for a static level, which belongs to the field of instruments and meters and is mainly used for the detection and calibration of the static level.

Background technique

The static level is mainly used as a measuring device for measuring the position settlement between two points or between multiple points. The principle of connecting device is adopted to keep the liquid level between multiple points consistent, so as to realize high-precision relative position detection. It is widely used in the implementation of large buildings, such as bridges, tunnels, hydropower stations and other buildings and relative settlement detection caused by internal structural deformation.

The current calibration method and measuring device of the static level are not perfect enough, it is difficult to achieve high-precision calibration, and it is difficult to meet the current calibration requirements.

detailed description

The utility model relates to a device for calibrating a portable static level based on the measurement of a height gauge, which belongs to the field of test and measurement and is mainly used for the detection and calibration of the static level. Static levels are widely used. In order to meet the calibration and calibration needs of high-precision static levels, a calibration device for static levels is designed.

The specific implementation manners of the present invention will be further introduced in detail in conjunction with the accompanying drawings.

The whole set of devices is installed and fixed on the platform (6), and the liquid level in the water storage tank (3) is raised or lowered by changing pads (7) of different thicknesses. Since the liquid level pipe (2), the water storage tank (3), the working liquid connecting pipe (4) and the static level (5) constitute a connector, the liquid level in the container (52) of the static level and the liquid level pipe (2) ), the float (53) of the static level floats in the working liquid level, and drives the connecting rod above the float (53) of the static level to float or sink, and passes through the displacement sensor (51) of the static level Measure the height of the working liquid level in the static level (5). Therefore, the detection and calibration of the static level (5) is realized by measuring the height of the working liquid in the liquid level tube (2).

When carrying out the calibration work, the liquid level of the water storage tank (3) is changed by replacing pads (7) of different thicknesses. After the liquid level in the water storage tank (3) is stable, adjust the height of the height gauge (1) during use so that the horizontal line of the cross mark in the reading microscope (8) is at the same level as the liquid level in the water storage tank (3) On, read the reading of the altimeter (1) and the reading of the displacement sensor (51) of the static level, as the height of the current liquid level. Within the measuring range of the static level (5), different liquid levels can be selected by replacing multiple pads (7) of different thicknesses for comparison between the height gauge (1) and the displacement sensor (51) of the static level. Thereby, calibration and calibration of the static level (5) are realized.

The device has a simple structure and high detection accuracy, and can meet the calibration and calibration requirements of the static level.
