[0003] However, when the existing line-of-sight measuring device is used for geographical surveying and mapping in rainy days, rainwater easily falls on the objective lens and affects the line of sight, and the objective lens needs to be manually wiped many times, which is time-consuming and laborious, and the line-of-sight measuring device is exposed to the air for a long time. It is easy to make the dust on the construction site adhere to the objective lens, resulting in blurred vision, and manual wiping is less effective for cleaning the dust at the edge

Embodiment
[0042] Example: Please refer to Figure 1 to Figure 8 :
[0043] The present invention proposes a line-of-sight measuring device based on optical point taking for surveying and mapping geography, comprising: a main body 1, a focusing hand wheel is installed on the side of the main body 1, and a side groove 2 is provided on the side of the main body 1; side grooves 2, side grooves 2 It is an annular structure, and the side plate 201 outside the side tank 2 is installed on the side of the main body 1; the inner tank 3, the inner tank 3 is arranged inside the main body 1, and the outer cylinder 302 outside the inner tank 3 is installed on the side of the main body 1; The crossbar 4 is a cylindrical structure, and the crossbar 4 is rotatably installed on the side of the main body 1 , and the crossbar 4 is located under the outer tube 302 .
[0044] Furthermore, according to an embodiment of the present invention, as figure 1 and figure 2As shown, the main body 1 includes: a ba...

The invention provides a line-of-sight measuring device for surveying and mapping geography based on optical point-taking, which relates to the technical field of painting, and includes a main body, the side of which is provided with a side groove; Installed on the side of the main body; the inner tank is set inside the main body, and the outer cylinder outside the inner tank is installed on the side of the main body; the cross bar is a cylindrical structure, and the cross bar is rotatably installed on the side of the main body, and the horizontal The rod is located below the outer cylinder. The rain falls in the water box and presses the vertical bar to move downward, so that the vertical bar loses its fixation to the clamping plate. Under the action of the spring, the shutter moves outward on the top of the outer cylinder, so that the shutter blocks the objective lens parts inside the outer cylinder. , to prevent rainwater falling on the objective lens from affecting the line of sight, and solve the problem that when the existing line-of-sight measuring device is used for geographical surveying and mapping in rainy days, rainwater easily falls on the objective lens and affects the line of sight, and the objective lens needs to be manually wiped many times, which is time-consuming and laborious.
Description
technical field [0001] The invention relates to the technical field of surveying and mapping equipment, in particular to a line-of-sight measuring device for surveying and mapping geography based on optical point taking. Background technique [0002] The line-of-sight measurement is to use the line-of-sight wire on the cross-hair reticle in the telescope of the level to read on the line-of-sight ruler. A device that is simple and less limited by the terrain and the distance and height difference. [0003] However, when the existing line-of-sight measuring device is used for geographical surveying and mapping in rainy days, rainwater easily falls on the objective lens and affects the line of sight, and the objective lens needs to be manually wiped many times, which is time-consuming and laborious, and the line-of-sight measuring device is exposed to the air for a long time. It is easy to make the dust on the construction site adhere to the objective lens, resulting in blurre...
