Total station objective lens protection device through soft material and alkaline fluid

Abstract

The invention discloses a total station objective lens protection device through a soft material and alkaline fluid. The total station objective lens protection device structurally comprises a horizontal micro-motion spiral, a chassis, a control panel, an eyepiece, a lens base, a handle, a U-shaped seat, and an objective lens sharpness protection device. The chassis is movably connected to the lower end of the U-shaped seat, the handle is fixed to the upper end of the U-shaped seat by screws, the horizontal micro-motion screw is mechanically connected to the lower end of the front surface of the U-shaped seat, the control panel is welded to the lower end of the right side of the U-shaped seat, the lens seat is movably connected to the middle section of the U-shaped seat, the eyepiece is connected to the right end of the lens seat in a glue mode, and the objective lens sharpness protection device is welded to the left end of the lens seat. The total station objective lens protection device is provided with the objective lens sharpness protection device, and a quantitative liquid discharge structure and a deflection cleaning structure cooperate with each other, so that dust and finesand on an objective lens are perfectly cleaned, the mirror surface is not damaged, the service life of the objective lens is prolonged, the mapping precision is ensured, and the practicability is high.

Description

technical field

[0001] The invention is a protective device for a surveying and mapping instrument used in building construction, in particular to a protective device for an objective lens of a total station through soft materials and alkaline fluid. Background technique

[0002] National economic development is inseparable from the construction of infrastructure. Infrastructure includes bridges, railways, roads, and various buildings. During the construction of these facilities, in order to ensure the accuracy of construction, various surveying and mapping instruments are needed. Among them, the total station The instrument is a very commonly used surveying and mapping instrument, but on the construction site, the environment is poor, and dust often occurs when there is a strong wind, so there will be a problem; during the use of the total station, the wind blows fine sand and Dust will fall on the surface of the objective lens, sometimes mixed with a small amount of water ...
