Description

Technical Field

[0002] A static level is a precision instrument used to measure elevation differences and their changes. A static level is typically installed on a pier of equal height to the object being measured or on the contour line of the wall. It usually uses a field data acquisition box with built-in standalone software to automatically collect data and store it in the field acquisition system. The data is then transmitted to a backend network software via wired or wireless communication, thus enabling automated observation.

[0015] According to another aspect of the present invention, a method for calibrating a hydrostatic level is provided.

[0016] Includes the following steps:

[0017] First, place the positioning clip on the outside of the liquid storage tank on the hydrostatic level, so that the inner side of the positioning clip fits against the outer side of the liquid storage tank.

[0018] The drive motor runs, and the motor drives the drive arm, which in turn drives the connecting rod three, causing the connecting rod three to pull the triangular rotating plate to rotate at an angle. This causes the connecting rod one and the connecting rod two to move up and down, thereby driving the support plate and the lower plate to move closer to the horizontal plate at the same time.

[0019] Then the fourth mounting bracket is installed on the object being measured;

[0020] When the storage tank tilts, the horizontal plane of the beam will change;

[0021] The support rod pulls the cylinder to slide between two inclined planes. 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 change. The verticality of the cylinder is monitored by the pointer in the vertical angle monitoring dial below.

[0022] After the vertical angle of the cylinder is found to have changed, the adjusting shaft adjusts the angle of the U-shaped angle adjusting plate to adjust the vertical angle of the cylinder to a suitable angle.

[0023] This is used to calibrate the verticality of the storage tank.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0025] During installation, the storage tank is mounted on a support plate. The support plate is pressed against a horizontal plate by the drive support auxiliary unit, with the lower plate abutting against the horizontal plate. The entire device is then installed and fixed to maintain the stability of the support. After prolonged operation, the vertical angle of the storage tank will shift, causing the positioning clamp on the storage tank to shift as well. This will affect the horizontal plane of the beam frame. The vertical angle adjustment unit connected below will detect the angle shift and promptly calibrate the angle to keep the storage tank in a vertical position, facilitating the use of the static level.

[0026] The liquid storage tank is installed on the support plate, and the resulting vertical force is directly applied to the horizontal plate. The horizontal plate will then receive a downward vertical force. The lower plate abuts against the horizontal plate, and there will be an upward pushing force below the horizontal plate. The pushing force and the vertical force above will collide, which improves the support stability of the liquid storage tank, reduces the angular deviation caused by the liquid storage tank during long-term operation, and allows the verticality of the liquid storage tank to be maintained for a longer period of time.

[0027] This static level device offers better installation stability and stronger support for the vertical angle, facilitating timely calibration of any deviations in the vertical angle, increasing its usability, and reducing the hassle of manual adjustments. Attached Figure Description

[0042] A method for calibrating a hydrostatic level includes the following steps:

[0043] S101: First, place the positioning clamp 10 on the outside of the liquid storage tank on the hydrostatic level, so that the inner side of the positioning clamp 10 fits against the outer side of the liquid storage tank.

[0044] S103: Drive motor 22 runs, motor 22 drives drive arm 27, drive arm 27 drives connecting rod 3 28, connecting rod 3 28 pulls triangular plate 29 to rotate at an angle, so that connecting rod 1 30 and connecting rod 2 31 move up and down, thereby driving plate seat 37 and lower plate 41 to move towards horizontal plate 4 at the same time.

[0045] S105: Then install the fourth mounting bracket 38 on the object being measured;

[0046] S107: When the storage tank tilts, the horizontal plane of beam 9 will change;

[0047] S109: The support rod 8 pulls the cylinder 44 to slide between the two inclined planes 43. Under the action of the return spring 52, the circular bottom column 50 is always in close contact with the bottom surface of the U-shaped angle adjustment plate 14, and the arc end 46 is in close contact with the bottom surface of the angle adjustment pressure rod 45. When the vertical angle of the cylinder 44 changes, the vertical angle of the U-shaped angle adjustment plate 14 will change.

[0048] S1011: After the change in the vertical angle of cylinder 44 is detected, the adjusting shaft 47 adjusts the angle of the U-shaped angle adjusting plate 14 to adjust the vertical angle of cylinder 44 to a suitable angle.

[0049] S1013: This is used to calibrate the verticality of the storage tank.

[0050] Detailed usage and function of this embodiment:

[0051] In use, the calibration device for this hydrostatic level first installs the storage tank on the fourth mounting base 38, drives the motor 22 to run, and the motor 22 drives the drive arm 27 to rotate. After the drive arm 27 rotates, it drives the connecting rod 3 28 to move. 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 irregular plate 26, the triangular rotating plate 29 will pull the connecting rod 1 30 upward and the connecting rod 2 31 downward. The connecting rod 1 30 will then pull the lower lifting plate 39 upward, and the lower slider 25 will slide upward on the track 23. The connecting rod 2 31... After moving downwards, pressing down on the upper lifting plate 32, the upper slider 24 will slide down on the track 23, causing the support plate 37 and the lower plate 41 to move towards the horizontal plate 4 simultaneously until the horizontal plate 4 is pressed down. Then, the fourth mounting base 38 is installed in the appropriate position on the object being measured. At the same time, the first mounting base 1, the second mounting base 6, and the third mounting base 3 are installed in the appropriate positions on the object being measured. Then, the positioning clamp 10 is sleeved on the outside of the liquid storage tank on the hydrostatic level, and the inner side of the positioning clamp 10 is made to fit against the outer side of the liquid storage tank. The positioning clamp 10 is then tightened and fixed by the nut.

[0052] When the liquid storage tank is in prolonged use and an angular deviation occurs, the positioning clip 10 fitted on the surface of the liquid storage tank will tilt horizontally due to the change in the verticality of the liquid storage tank. This will affect the horizontal plane of the beam 9. When the horizontal plane of the beam 9 tilts, it will drive the support rod 8, causing the support rod 8 to pull the cylinder 44. A sphere is set at the bottom center of the cylinder 44, which is embedded in the bottom center of the groove formed by the two inclined planes 43. When the cylinder 44 tilts vertically due to the influence of the support rod 8, the two sides of the cylinder 44 connected to... When the angle adjustment lever 45 contacts the top surface of the arc end 46, the angle will change. 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 tilt 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 so that the liquid storage tank always remains at a vertical angle.

However, it should be understood that the present invention is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
