Description

Technical Field

[0001] The utility model relates to a topographic surveying device for water conservancy projects suitable for different terrains, belonging to the technical field of topographic surveying devices. Background Art

[0002] Water conservancy facilities are facilities that control, regulate, develop, utilize and protect natural water in order to reduce and eliminate water and drought disasters, and utilize water resources to meet the needs of human society and the natural environment. Topographic surveying equipment is needed to measure the terrain in water conservancy projects.

[0003] According to the announcement number CN214200110U, a topographic surveying device for water conservancy projects is disclosed. The utility model relates to the technical field of topographic measuring equipment. When the servo motor is turned on, the two gears rotate in opposite directions, so that the rack moves vertically downward along the direction of the fixed port, and drives the slide plate and the measuring head to move vertically downward. When the slide plate abuts against the blocking member, the measuring head is located in the protective box, and the bottom of the shielding plate abuts against the top of the protective box, which can effectively protect the measuring head, thereby helping to extend the service life of the measuring head. When the above device is in use, when the terrain encountered is inclined or the ground is uneven, the device cannot effectively ensure the levelness of the measuring head. At the same time, it is easy for some universal wheels to fail to contact the ground, thereby failing to ensure the stability of the device, reducing the applicability of the device.
