Problems solved by technology

However, the problem brought by the use of buried seismometers is that once the seismometers are buried in a small-aperture underground or on the seabed, it will be difficult to manually adjust the horizontal state, and the initial buried state of the seismometers is unknown. The aperture of the seismometer also has a certain slope. If the seismometer is not leveled, the normal working condition of the seismometer cannot be guaranteed.

Abstract

The invention discloses a cross shaft leveling device. The cross shaft leveling device comprises a shell and a leveling assembly inside the shell; one end of the leveling assembly is fixedly connectedwith the shell, and the other end of the leveling assembly is connected with a to-be-leveled instrument through a first adjusting shaft assembly and a second adjusting shaft assembly; the first adjusting shaft assembly is provided with a first rotating shaft, and the second adjusting shaft assembly is provided with a second rotating shaft; and the to-be-leveled instrument can turn within an adjusting angle range relative to the leveling assembly by taking the first rotating shaft and the second rotating shaft as the rotating shafts. According to the cross shaft leveling device, the to-be-leveled instrument can be automatically leveled, and the normal working state of the to-be-leveled instrument is guaranteed.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a cross-axis leveling device. Background technique [0002] Some measuring instruments need to be adjusted to a horizontal state before work to ensure normal operation, and the leveling of some measuring instruments is done manually. [0003] For some measuring instruments with special installation positions, manual adjustment cannot be realized. For example, deep well seismometers and submarine seismometers have harsh working environments. In order to avoid the impact of environmental factors on seismometers and reduce the measurement accuracy, and to prevent economic losses caused by man-made damage, the application of embedded seismometers has become a trend. However, the problem brought by the use of buried seismometers is that once the seismometer is buried in a small-aperture underground or on the seabed, it will be difficult to manually adjust the horizontal...
