Description

Technical Field

[0001] The utility model relates to the technical field of land surveying and mapping, in particular to a land on-site levelness measuring device. Background Art

[0002] In the field of land surveying, the level measurement of land sites is a crucial task, which directly affects the quality of land development and construction projects and the subsequent use effect. However, traditional land site level measurement equipment often faces some technical challenges in practical applications, especially in the fixing of equipment brackets and the adjustment of levelness.

[0003] First, in terms of the fixation of the equipment bracket, traditional measurement equipment usually relies on simple tripods or other types of brackets for fixation. Although these brackets can support the equipment to a certain extent, they are often difficult to ensure sufficient stability under complex and changing terrain and geological conditions. Especially in environments with strong winds, soft ground or large slopes, the bracket is prone to shaking, resulting in errors in the measurement results and even the risk of equipment damage.

[0004] Secondly, in terms of level adjustment, most traditional measuring equipment uses manual adjustment. The operator needs to manually adjust the height or angle of the bracket according to the equipment's level indicator to achieve horizontal placement of the equipment. However, this adjustment method is not only cumbersome and inefficient, but also difficult to achieve precise adjustment effects. Due to the existence of human eye observation errors and operation errors, it is difficult to ensure that the equipment is completely horizontal even after multiple adjustments. This not only affects the accuracy of the measurement, but also increases the workload of the operator. Utility Model Content
