The indium steel ruler is a tool for leveling, so the indium steel ruler is mostly used for measurement in the field or places needing building construction, the indium steel ruler is usually used in cooperation with a leveling instrument, the indium steel ruler is placed at a measuring point, the leveling instrument reads the bar codes 6, when the indium steel ruler is perpendicular to a measuring position, the precision of measured data is highest, so that the terrain is uneven or the geology is too soft, or the indium steel ruler is blown by wind, the inclination condition of the ruler is easy to occur in the using process, once the inclination condition occurs, wrong data is directly caused to the measuring result, so that the inconvenience is caused to later data arrangement and building construction, in order to avoid the inclination of the ruler caused by wind blowing or other reasons in the using process, so that the measured data is inaccurate, as shown in figure 5, as a preferred technical scheme, the inclination angle sensor 20, the controller 21, the pump 27 and the water storage cavity 22 are sequentially arranged in the main scale frame 2, the axial central lines of the inclination angle sensor 20, the controller 21, the water storage cavity 22 and the pump 27 are all overlapped with the axial central line of the main scale frame 2,
the inclination angle sensors 20 and the pumps 27 are respectively connected with the controller 21 one by one;
a plurality of balance cavities are arranged above the pump 27, the water inlet end of the pump 27 is communicated with the water storage cavity 22, the pump 27 is provided with a plurality of water outlet ends, and the water outlet ends are respectively connected with one balance cavity in a one-to-one correspondence manner.
In order to avoid the inclination of the scale caused by wind blowing or other reasons during the use of the scale, thereby causing inaccuracy of the measured data, a preferable technical proposal is that the balance cavity comprises a first balance cavity 23, a second balance cavity 24, a third balance cavity 25 and a fourth balance cavity 26, the first balance cavity 23, the second balance cavity 24, the third balance cavity 25 and the fourth balance cavity 26 are in a fan-shaped structure and are uniformly distributed in the main scale frame 2,
the tilt sensor 20, the controller 21, the pump 27 and the water storage cavity 22 are all cylindrical structures. The tilt sensor 20 integrates the MCU, the MEMS accelerometer, the analog-to-digital conversion circuit, and the communication unit on a very small circuit board. The inclination data such as the angle, the inclination azimuth and the like can be directly output. The tilt sensor 20 is preferably a vg (vertical gyro) tilt sensor.
The specific working principle is as follows: the tilt sensor 20 is disposed at the inner upper part of the main scale frame 2, so that the measurement of the inclination of the main scale frame 2 can be more accurate, when the main scale frame 2 is tilted, the tilt sensor 20 transmits the measured tilt information to the controller 21, after the controller 21 receives the tilt information, the pump 27 is started, the pump 27 injects the water in the water storage cavity 22 into the balancing cavity in the tilted opposite direction, for example, the first balancing cavity 23 is in the west direction, the second balancing cavity 24 is in the south direction, the third balancing cavity 25 is in the east direction, and the fourth balancing cavity 26 is in the north direction; when the main scale frame 2 inclines 1 degree towards the west direction, the inclination angle sensor 20 transmits the information to the controller 21, at this time, the controller 21 starts the pump 27, the pump 27 injects the water in the water storage cavity 22 towards the east direction to achieve the purpose of balancing, so that the water in the water storage cavity 22 is injected into the third balancing cavity 25, the inclination angle of the main scale frame 2 inclining 1 degree towards the west direction is adjusted by water injection until the inclination angle measured by the inclination angle sensor 20 disappears, and the controller 21 closes the pump 27 to stop the water storage cavity 22 from injecting water into the third balancing cavity 25. Therefore, the inaccuracy of measurement data caused by the inclination of the main scale frame during measurement can be avoided.
When the main scale frame 2 is inclined, the top of the main scale frame is the most sensitive position, so in order to make the information measured by the tilt sensor 20 more sensitive and accurate, the tilt sensor 20 is preferably arranged at the top of the main scale frame 2; meanwhile, in order to increase the chassis weight of the main scale frame 2 and ensure the stability of the main scale frame 2, it is preferable to dispose the water storage cavity 22 near the bottommost portion of the main scale frame 2.
In order to avoid the situation that when the water in the water storage cavity 22 is completely filled into the balance cavities thereof by the pump 27 or the water in each balance cavity is full, and the inclination angle is detected by the inclination angle sensor 20, each balance cavity is disabled, according to a preferred technical scheme, as shown in fig. 7, each balance cavity is provided with a pipeline 33, each pipeline 33 is communicated with the water storage cavity 22, each pipeline 33 is provided with an electromagnetic valve 37, and the electromagnetic valves 37 are respectively connected with the controller 21 one by one.
After the water in the water storage cavity 22 is completely drained or the water in each balance cavity is full, the inclination angle sensor 20 detects the inclination angle information, transmits the inclination angle information to the controller 21, the controller 21 obtains the inclination direction according to the inclination angle information, opens the corresponding electromagnetic valve 37 on the balance cavity on the side of the inclination direction, and after the electromagnetic valve 37 is opened, the balance cavity in the inclination direction is communicated with the water storage cavity 22, so that the water in the balance cavity in the inclination direction can be introduced into the water storage cavity 22, thereby reducing the weight in the inclination direction and achieving the purpose of balancing the verticality of the main ruler frame 2.
For example, the first balance chamber 23 is in the west direction, the second balance chamber 24 is in the south direction, the third balance chamber 25 is in the east direction, and the fourth balance chamber 26 is in the north direction; when the main scale frame 2 inclines 1 ° to the west direction, the tilt sensor 20 transmits the information to the controller 21, the controller 21 opens the electromagnetic valve 37 corresponding to the first balance cavity 23 representing the west direction, after the electromagnetic valve 37 is opened, the pipeline 33 communicates the first balance cavity 23 with the water storage cavity 22, at this time, the water in the first balance cavity 23 flows into the water storage cavity 22 until the tilt sensor 20 does not detect the tilt information, and the controller 21 closes the electromagnetic valve 37, so that the main scale frame 2 can achieve the purpose of being horizontal and vertical.
The more the balance cavities, the water outlets of the pumps and the pipelines 33 are, the higher the balance precision of the inclination angle is, that is, the more the balance cavities are, the more fan-shaped balance cavities with the same cross-sectional area form a cylinder, that is, the more the fan-shaped balance cavities are, the more the water outlets of the pumps and the pipelines 33 are correspondingly arranged, and the higher the precision of the balance after the inclination is.
In order to avoid carrying a plurality of scales and reduce the scattered of the measurement objects carried during outgoing measurement, the preferable technical scheme is that, as shown in fig. 4, an auxiliary scale frame 18 is arranged on the back surface of the main scale frame 2, the main scale frame 2 and the back surface of the auxiliary scale frame 18 are arranged close to each other, the upper part of the main scale frame 2 is hinged to the upper part of the auxiliary scale frame 18, a concave notch is arranged on the front surface of the auxiliary scale frame 18, and an auxiliary scale indium steel band 19 is arranged in the notch.
The auxiliary scale frame 18 is used as an auxiliary measuring tool, when the measurement data needs to be verified for many times after the measurement of the main scale frame 2 is finished, the hinged part of the auxiliary scale frame 18 and the main scale frame 2 can be rotated, so that the auxiliary scale frame 18 and the main scale frame 2 are rotated from a folded state to an opened state, and the bottom of the auxiliary scale frame 18 is fixed on the main scale pad 7, so that the measurement for many times can be conveniently realized, and the measurement accuracy is improved.
A battery 35 is further arranged below the main scale frame 2, and the battery 35 is respectively connected with the controller 21, the inclination angle sensor 20 and the pump 27 one by one.
