Description

Technical Field

[0001] The present invention relates to the technical field of optoelectronic equipment and instruments, and in particular to a bearing base with a leveling function. Background Art

[0002] In the field of photoelectric detection imaging equipment and instruments, the supporting base is an important component for achieving stable operation of the equipment. However, in outdoor use environments, the performance of the equipment is often affected because the installation conditions are difficult to meet the horizontal requirements. Therefore, it is particularly important to design a base with a leveling function to adapt to the needs of different installation sites. Although automated and intelligent leveling technologies have been applied in related devices, the reliability of these devices is often difficult to guarantee in some environments such as areas without electricity or insufficient electricity, and high humidity environments. In contrast, the traditional mechanical leveling system has the characteristics of simple structure, low cost, and intuitive operation. It can meet the needs of small-range angle adjustment, and this type of leveling base shows good durability and reliability during installation and use. Therefore, it is still of practical significance to develop a mechanical leveling base that is easy to operate.

[0003] Currently, there are four main ways to level the equipment bearing base, namely traditional mechanical jack leveling, hydraulic drive leveling, electric drive leveling, and intelligent leveling.

[0004] The adjustment accuracy of traditional mechanical jacks is limited, and the load-bearing conditions of the bearing parts in the tilted state are poor, which can easily lead to wear and jamming, affecting the service life.

[0005] Hydraulic-driven leveling can achieve relatively precise leveling, but it requires regular maintenance and upkeep, the equipment is prone to leakage or failure, and its reliability is low in extreme environments.

[0006] Electric drive leveling is highly dependent on power supply, which limits its application in environments without electricity or with insufficient power, as well as in harsh environments.

[0007] Although the intelligent leveling system can achieve automatic leveling, it is highly dependent on the accuracy of the sensor and has a high overall integration level, which leads to a significant increase in development and maintenance costs. Summary of the Invention
