Abstract

The present invention discloses an integrated intelligent measuring vehicle for multi-dimensional hydrodynamic parameters of wide and shallow braided rivers, including: a measuring vehicle and an RTK system base station; the measuring vehicle includes a frame, and a mobile mechanism is symmetrically connected to both sides of the frame; an RTK system mobile station is mounted on the frame, and the RTK system mobile station is wirelessly connected to the RTK system base station; a water level sensor is mounted on the frame through a pan / tilt. In the present invention, the telescopic detection frame can be driven by an adjustment component to shrink and rotate and fold to be mounted on the frame, so that it is more stable when moving and prevents tipping. During measurement, the telescopic detection frame is synchronously driven by the adjustment component to rotate and unfold into a vertical state and telescope and unfold, so that the flow velocity detection component can be driven to rise and fall through the adjustment mechanism, so as to adjust the measurement position of the flow velocity detection component according to the actual water level depth to achieve accurate measurement of the average velocity of the river.
