Embodiment 1

[0032] Example one: see figure 2 The detection device 3 is a dial indicator 31, the dial indicator is preferably a digital display electronic dial indicator, the measurement accuracy of the dial indicator 31 is greater than the measurement accuracy of the static level 1; The measuring rod head 311 is connected to the moving part 22, and the dial indicator 31 detects the amount of movement of the moving part 22; the control part 21 includes a rotating shaft 211 and a wheel 212, and the rotating shaft 211 is rotatably connected to The wheel 212, the moving part 22 includes a screw 221 and a bracket 222, the wheel 212 is sleeved on the screw 221 through threads, and the upper end of the screw 221 is fixedly connected to the bracket 222 The lower end of the screw 221 is connected to the detection device 3; preferably, the screw 221 and the bracket 222 are integrally formed. One end of the rotating shaft 211 is provided with a first gear, and the outer side surface of the wheel 212...

Embodiment 2

[0038] Example 2: Refer to image 3 , There are two static level gauges 1, and the liquid storage tanks 11 of the two static level gauges 1 are connected by a connecting pipe 12. At this time, in the preparation stage, each static level 1 is equipped with a corresponding calibration device of the static level of the present invention. One of the lifting devices 2 of the calibration device of the static level of the present invention is fixed and the other is adjusted. A lifting device 2 of the static level calibration device of the present invention records the detection data of the sensor 13 of the static level 1 and the measurement data of the detection device 3, and compares it to determine the measurement accuracy of the static level 1. For other unmentioned parts, refer to Embodiment 1.

Abstract

The invention discloses a calibration device and a calibration method for a static force level gauge. The calibration device comprises a lifting device and a detection device, the lifting device comprises a control piece and a moving piece, the control piece is connected with the moving piece, the control piece controls the moving piece to move up and down, the moving piece is further connected with the detection device, the detection device detects the amount of movement of the moving piece, and the moving piece is used to bear the static force level gauge. The calibration device for the static force level gauge has the advantages that: the calibration device for the static force level gauge uses the lifting device to regulate the lifting of the static force level gauge to simulate the floating and sinking of a test point, then the calibration is much closer to the actually acquired data of a project, the data measured by the detection device are compared with the data detected by thestatic force level gauge, the measurement accuracy of the static force level gauge is more intuitively judged, the testing procedure is simple, and the unnecessary errors are avoided.

Description

【Technical Field】 [0001] The invention relates to the field of construction engineering instruments and meters, in particular to a calibration device and a calibration method of a static level. 【Background technique】 [0002] A static level is a construction project settlement monitoring device that measures the relative elevation changes between two or more points. It is mainly used to monitor the vertical displacement of large storage tanks, dams, nuclear power plants, high-rise buildings, foundation pits, tunnels, bridges, subways, etc. Using the principle of connected liquid, the liquid level of the liquid storage tank of the static level gauge connected by the connecting pipe is always on the same level. When the settlement of each observation occurs, it will cause the increase or decrease of the liquid in each liquid storage tank. The reading of the sensor of the static level gauge understands the change of the liquid level of the static level gauge at each test point, so ...
