Description

Technical Field

[0001] The present invention relates to the technical field of static levels, and in particular to a static level calibration device and method. Background Art

[0002] A static level is a precision instrument for measuring elevation differences and their variations. It's typically mounted on a measuring pier or on a wall contour at the same height as the object being measured. Data is typically collected automatically using a standalone acquisition software built into a field acquisition box. This data is then connected to the internet via wired or wireless communication and transmitted to backend network software, enabling automated observation.

[0003] After a long period of use, a static level may become tilted (not in a vertical position), which will affect the liquid level in the liquid storage tank above it, causing the static level to become inaccurate, so a calibration device is needed to calibrate it.

[0014] According to another aspect of the present invention, a static level calibration method is provided.

[0015] The following steps are involved: First, place the positioning clamp on the outside of the liquid storage tank on the static level so that the inner side of the positioning clamp fits into the outer side of the liquid storage tank; The driving motor runs, and the motor drives the driving arm, which drives the connecting rod three through the driving arm, so that the connecting rod three pulls the triangular rotating plate to rotate at an angle, causing the connecting rod one and the connecting rod two to move up and down, thereby driving the supporting plate seat and the lower plate to move closer to the horizontal plate at the same time; Then, the fourth mounting base is mounted on the object to be measured; When the tank tilts, the horizontal plane of the beam will change; The support rod pulls the cylinder to slide between the two inclined surfaces. Under the action of the return spring, the circular bottom column is always kept in close contact with the bottom surface of the U-shaped angle adjustment plate, and the arc end is in close contact with the bottom surface of the angle adjustment pressure rod. When the vertical angle of the cylinder changes, the vertical angle of the U-shaped angle adjustment plate will also change. The verticality of the cylinder is monitored by the pointer on the vertical angle monitoring dial below. After the vertical angle of the cylinder is found to have changed, the adjusting shaft adjusts the angle of the U-shaped angle adjustment plate to adjust the vertical angle of the cylinder to a suitable angle; This is used to calibrate the verticality of the liquid storage tank.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are: When installing the static level device, the liquid storage tank is installed on the pallet seat, and the pallet seat is pressed onto the horizontal plate by driving the support auxiliary part, and the lower plate is against the horizontal plate. Then the entire device is installed and fixed to maintain the stability of the support. After the liquid storage tank has been in operation for a long time, the vertical angle will shift, and the positioning clamp clamped on the liquid storage tank will also shift in angle, and the horizontal plane of the beam will be affected. The vertical angle adjustment part connected below will detect the angle offset value, and then calibrate the angle in time to keep the liquid storage tank in a vertical state at all times, which is convenient for the use of the static level.

[0017] The liquid storage tank is installed on the pallet seat, and the vertical force generated is directly applied to the horizontal plate. The horizontal plate will receive the downward vertical force, and the lower plate will press against the horizontal plate. There will be an upward force under the horizontal plate, and the upward force will collide with the vertical force above, which improves the support stability of the liquid storage tank, reduces the angular deviation caused by long-term operation of the liquid storage tank, and allows the verticality of the liquid storage tank to be maintained for a longer time.

[0018] The static level device has better installation stability and stronger vertical angle support, which is conducive to timely calibration of vertical angle deviation, improves utilization rate, and reduces the trouble of manual adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Detailed usage and effects of this embodiment: When the calibration device of the static level is in use, the liquid storage tank is first installed on the fourth mounting seat 38, the driving motor 22 is operated, the motor 22 drives the driving arm 27 to rotate, and the driving arm 27 drives the connecting rod 3 28 to move after the rotation. The connecting rod 3 28 pulls the triangular rotating plate 29. When the triangular rotating plate 29 rotates counterclockwise on the right side of the side of the irregular plate 26, the triangular rotating plate 29 will pull the connecting rod 1 30 upward and pull the connecting rod 2 31 downward. The connecting rod 1 30 then pulls the lower lifting plate 39 upward, the lower slider 25 slides upward on the track 23, and the connecting rod 2 31 After going down, pressing the upper lifting plate 32 downward, the upper slider 24 will slide up and down on the track 23, so that the support plate seat 37 and the lower plate 41 are simultaneously moved closer to the horizontal plate 4 until the horizontal plate 4 is pressed, and then the fourth mounting seat 38 is installed on the appropriate position of the object to be measured, and the first mounting seat 1, the second mounting seat 6 and the third mounting seat 3 are respectively installed on the appropriate positions of the object to be measured, and then the positioning clamp 10 is put on the outside of the liquid storage tank on the static level, and the inner side of the positioning clamp 10 is fit with the outer side of the liquid storage tank, and the positioning clamp 10 is tightened and fixed with a nut.

[0029] When the liquid storage tank is in use for a long time, if the angle is offset, the positioning clip 10 set on the surface of the liquid storage tank will tilt as the verticality of the liquid storage tank changes, and the horizontal plane of the beam 9 will be affected. When the horizontal plane of the beam 9 tilts, it will drive the support rod 8, so that the support rod 8 pulls the cylinder 44. A sphere is provided at the bottom center of the cylinder 44, and the sphere is embedded in the bottom center of the groove formed by the two inclined surfaces 43. When the vertical angle of the cylinder 44 is tilted due to the influence of the support rod 8, the two sides of the cylinder 44 are connected. The angle at which the angle adjustment pressure rod 45 contacts the top surface of the arc-shaped end 46 will change, and the vertical angle monitoring disk 55 will detect the angle value of the U-shaped angle adjustment plate 14, and then adjust the shaft 47 according to the detected angle deviation value, adjust the inclination angle of the U-shaped angle adjustment plate 14, and straighten the vertical angle of the U-shaped angle adjustment plate 14. In this way, the verticality of the cylinder 44 will be calibrated, and then the angle of the liquid storage tank will be calibrated. Then, according to the calibrated angle, the installation of the liquid storage tank will be re-fixed to keep the liquid storage tank at a vertical angle at all times.
