A theodolite for municipal garden surveying and positioning

Abstract

The invention discloses a theodolite for municipal garden surveying and mapping and positioning, and relates to the technical field of garden surveying and mapping. The invention includes a mounting plate, a leveling box and an annular plate. The inside of the leveling box is provided with a liquid, a cover plate, a floating plate and several bushings. The floating plate is in the liquid, and a support rod is installed on the upper surface of the floating plate. A mounting base is connected, a theodolite is installed on the upper surface of the mounting base, a threaded rod is arranged on one surface of the shaft sleeve, a first movable screw sleeve is arranged on the side of the threaded rod circumference, and a moving rod is installed on both sides of the first movable screw sleeve. A propelling rod is installed on one surface of the rod, and one end of the propelling rod is connected with a fixing plate. In the present invention, a floating plate is placed in the liquid, and the buoyancy provided by the liquid enables the theodolite to float, and when the liquid is in a static state, the theodolite can be automatically placed in a horizontal state; a fixed plate is set, and when the floating plate is in the liquid, it is easy to shake , fix it through the fixing plate to prevent it from shaking and improve the accuracy of measurement.

Description

technical field [0001] The invention belongs to the field of garden surveying and mapping, in particular to a theodolite for municipal garden surveying and mapping. Background technique [0002] Theodolite is a measuring instrument designed to measure horizontal and vertical angles based on the principle of angle measurement. It is divided into two types: optical theodolite and electronic theodolite. The most commonly used one is the electronic theodolite. [0003] During the use of the existing theodolite, the position of the theodolite may be uneven, resulting in deviations in the measurement results. The leveling structure of the existing theodolite is generally adjusted manually, which is not only cumbersome but also easy to operate. The deviation makes the measurement results deviate from the actual situation and has a certain impact on the measurement results. In order to solve the above problems, a theodolite for municipal garden surveying and mapping is proposed. C...

[0003] During the use of the existing theodolite, the position of the theodolite may be uneven, resulting in deviations in the measurement results. The leveling structure of the existing theodolite is generally adjusted manually, which is not only cumbersome but also easy to operate. The deviation makes the measurement results deviate from the actual situation, and has a certain impact on the measurement results. In order to solve the above problems, a theodolite for municipal garden surveying and mapping is now proposed.
