Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering cost surveying and mapping, in particular to a construction engineering cost surveying and mapping total station device with an anti-fogging objective lens. Background Art

[0002] National economic development is inseparable from the construction of infrastructure, which includes bridges, railways, roads, and various buildings. During the construction of these facilities, various surveying and mapping instruments are needed to ensure construction accuracy. Among them, the total station is a very commonly used surveying and mapping instrument. However, on the construction site, the environment is poor, and dust often occurs when there is a strong wind, which will cause a problem. During the use of the total station, the strong wind will blow up fine sand and dust, which will fall onto the surface of the objective lens, and sometimes mixed with a small amount of water droplets, which will directly affect the measurement accuracy of the total station. If the mirror surface is wiped directly by hand, the fine sand will scratch the mirror surface, resulting in measurement deviation during the measurement process, and even making the mirror surface scrapped.

[0003] Moreover, the traditional total station objective lens is exposed. When construction workers use the equipment for observation and surveying, their skin is close to the objective lens. However, when the equipment is used outdoors in a lower temperature environment, human body temperature and moisture can easily cause water mist to form on the surface of the equipment's objective lens, requiring frequent wiping, which affects the equipment's observation efficiency.

[0004] Therefore, an engineering cost surveying and mapping total station device with anti-fogging objective lens is proposed. Utility Model Content
