Description

Technical Field

[0001] This utility model relates to the field of building monitoring instruments, and in particular to a monitoring instrument for the structure of ancient building materials. Background Technology

[0002] Ancient building material structure monitoring instruments are a type of instrument and equipment specifically designed for real-time and continuous monitoring of the state of ancient building materials and structures. They use various sensing methods such as strain gauges, displacement sensors, temperature and humidity sensors, corrosion probes, and acoustic emission sensors to monitor the stress, displacement, humidity, temperature, and corrosion environment of key parts such as walls, arches, towers, and ridges over a long period of time.

[0003] However, traditional ancient building material structure monitoring instruments are poor in terms of horizontal placement and positioning calibration. They can only make adjustments in three or four directions, and cannot make multi-angle horizontal adjustments, thus affecting the accuracy of horizontal adjustment. In addition, they lack a synchronous control mechanism that is in the same direction as the level plate, making it difficult to achieve highly repeatable position reproduction, resulting in the accumulation of long-term comparison errors.

[0004] Therefore, those skilled in the art have provided a structural monitoring instrument for ancient building materials to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a structural monitoring instrument for ancient building materials. This instrument is equipped with a positioning mechanism and a leveling mechanism. With the threaded engagement of a bidirectional screw and a threaded block, the user can adjust the elasticity of the tension springs in different directions through the coordination of the horizontal bubble tube. This allows the leveling plate to be adjusted to a horizontal position through eight-way adjustment, thereby improving the accuracy of the monitoring instrument installed on the mounting mechanism. This enables the device to be installed on ground with different horizontal inclinations, thus expanding its applicability. Furthermore, the positioning mechanism, through the meshing between bevel gears, controls multiple telescopic columns to simultaneously lift the leveling plate, thereby resetting the leveling plate to a horizontal position. This allows for the inspection, replacement, or resetting of each tension spring, facilitating adjustment and use in different positions and extending the service life of the leveling mechanism.

[0006] To achieve the above objectives, the present invention provides the following technical solution:
