Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy surveying and mapping equipment, and in particular relates to an underwater measurement RTK pole auxiliary device. Background Art

[0002] In water conservancy surveying and mapping operations, the points to be measured are often located in the center of rivers and channels. Due to the unknown underwater environment, the safety of surveyors cannot be guaranteed, and underwater measurement is difficult. At present, the main instruments for underwater measurement are underwater measurement unmanned boats and RTK equipment. However, when the water flow rate is fast, the underwater terrain is difficult to judge, and there are many waterfalls in the channel, only RTK equipment can be used to collect terrain points.

[0003] With the development of RTK technology and the integration of inertial measurement units (IMUs) and GNSS antenna technologies in recent years, RTK equipment has the function of tilt measurement (that is, the RTK centering rod measures the coordinate elevation of the measured point within a tilt angle of 30°). In water conservancy projects, it is often encountered that the measured point is located at the bottom of a channel or the center of a small channel with a channel width or a channel width of approximately 2-3 meters and a water depth of generally 0.5-2 meters. In this case, the surveyor cannot reach the measured point, and the tilt measurement function cannot collect data due to the large tilt angle, making the measurement more difficult. It also poses a hidden danger to the personal safety of the surveyor. Utility Model Content
