Description

Technical Field

[0001] The utility model relates to the technical field of measurement auxiliary equipment, and in particular to a construction engineering surveying and mapping total station. Background Art

[0002] The total station is a high-precision measuring instrument that integrates optical, mechanical and electrical technologies. It combines the functions of horizontal angle, vertical angle, distance (slant distance, horizontal distance) and height difference measurement. The application of total station in construction engineering surveying and mapping not only improves measurement efficiency and accuracy, but also provides strong guarantees for quality control and safety management of engineering projects.

Before using the total station, it is usually necessary to wipe the lens to reduce the adverse effects of impurities attached to the lens on the measurement. Generally, it is wiped with a wiping cloth. Over time, the lens is easily scratched, thereby reducing the service life of the total station. Utility Model Content

The cone 3 is opened and then adjusted to a suitable length through the fixing assembly, and then the device is opened for use. When the lens 7 needs to be cleaned, the controller 5 controls the total station 6 to rotate so that the lens 7 is pointed downward at the nozzle 17 and the servo motor 8 is started. The servo motor 8 drives the cam 9 to rotate. When the cam 9 rotates, it intermittently pushes the connecting plate 14, and the connecting plate 14 pushes the push rod 11. The push rod 11 drives the piston 12 to slide inside the air cylinder 10, squeezing the air. The air passes through the air pipe 16 and then through the nozzle 17 to spray out towards the lens 7 The dust attached to the cylinder 10 is cleaned and blown off.

After adjusting to the appropriate position, the lever 22 is pushed again, and the lever 22 loses the supporting force against the frame 18. The elastic force of the spring 23 pushes the baffle 21, and the baffle 21 drives the insertion rod 20 to be reinserted into the inserting cone 3, so that the inserting cone 3 is stably installed.
