Embodiment Construction

[0016] see figure 1 , Fig. 2, in the present embodiment, on base body 1, level sensor 2 is set, and level sensor 2 comprises the Y-shaped three-way pipe 3 that is arranged on the plane of base body 1, and the pipe body of three-way pipe 3 is an insulator, and inside the pipe The conductive fluid 4 is contained, each pipe end is provided with a tilt detection switch, and a height adjustment mechanism 5 is provided at a corresponding position of the base body 1 .

[0017] figure 1 As shown, one switch contact of the inclination detection switch is the conductive liquid 4, and the conductive liquid 4 presents different liquid level heights at the pipe end of the three-way pipe 3 with the different inclination angles of the level sensor 2, and the other contact of the inclination detection switch The switch contact is a conductive needle 6 located at the pipe end of the tee pipe 3 and fixedly arranged above the conductive liquid 4 . When a pipe end of the three-way pipe 3 of the...

Abstract

The invention relates to an self-adjusting foundation bed of level and theodolite, which is characterized in that it arranges horizon sensor on the adjusted base including a Y-type insulating triplet pipe with conductive liquid arranged on the surface of the base; each end of the pipe arranges a slope detesting switch with one contact is conductive liquid, while the other contact is a conductive needle which is fixed on the upper part of the conductive liquid and laid on the pipe end of the triplet pipe; it arranges height adjuster on the corresponding location of the base which is driven by the motor and which is a screw mechanism of the pipe end height of the triplet pipe; the motor uses the switch signal outputted form the corresponding pipe end slope testing switch as opening and ending control signal. The invention improves the surveying and mapping precision of level and theodolite.

Description

Technical field: [0001] The invention relates to an accessory of a level or theodolite, more specifically a device used in the level or theodolite to realize automatic leveling of the level or theodolite. Background technique: [0002] Surveying instruments such as levels and theodolites are widely used in elevation surveying, engineering surveying and construction surveying, and they have a common feature in the process of use—requiring surveyors to manually level them. The process of leveling and the subjective factors of surveyors will directly affect the progress and accuracy of surveying and mapping. Although the automatic leveling level is now widely used, it is still inevitable to level it, and for theodolite, the leveling process will be more complicated. Invention content: [0003] In order to avoid the problems in the prior art, the present invention provides an automatic leveling base for a level instrument and a theodolite, so that the surveying and mapping pr...
