Novel optical level indicator

Abstract

The invention relates to the field of mapping equipment and aims to provide a novel optical level indicator. According to the technical scheme provided by the invention, the novel optical level indicator comprises a connector and a hammer block, wherein the connector is connected with a mapping bracket through a connecting component; the connector is composed of an upper section and a lower section which are coaxially arranged, wherein the upper section is of a disc shape, and the lower section is of a cylindrical shape; a through hole is formed in the lower section of the connector along the axial direction; a dotting light beam emitter is arranged in the through hole; the emitting direction of the dotting light beam emitter is consistent to the axial direction of the through hole; three first connecting components are arranged at the lower end of the lower section of the connector; a light channel is arranged at the center of the hammer block; a concave lens is arranged at the lower end of the upper section of the light channel; a convex lens is arranged on the lower section of the light channel; and the light beam emitted by the dotting light beam emitter is amplified by the concave lens and guided by the convex lens and then is formed into an amplified light spot under the hammer block. The novel optical level indicator is beneficial for the mapping personnel to observe, has a simple structure and is very convenient to use.

Description

technical field [0001] The invention relates to the field of surveying and mapping equipment, in particular to a novel optical level. Background technique [0002] Surveying and mapping instruments are instruments and devices designed and manufactured for data acquisition, processing, and output for surveying and mapping operations. It mainly includes theodolite, level, rangefinder, total station, global positioning system (GPS), etc. Before using the surveying and mapping instrument, in order to improve the measurement accuracy, it is necessary to carry out centering and leveling, that is, to align the center of the instrument with the surveying site, and then make the surveying and mapping The instrument remains horizontal. The circular level is a disc-shaped bubble level. The bubble level is usually set directly on the bracket installation platform (that is, the top of the centering rod), and is used to check whether the installation plane of the surveying and mapping in...

Problems solved by technology

[0003] But there are huge defects in this method. On the one hand, because the circular level is usually small, the bubbles are even smaller, which is not convenient for surveyors to observe, especially in poor light conditions; on the other hand, When adjusting the support legs of the bracket, surveyors and mappers need to get up to observe the circular level, and then bend down to adjust the support legs. After repeating many times, they can finally adjust the surveying and mapping instrument, which is time-consuming and laborious, especially when the bracket is high. more obvious
