Doppler flow measuring device

Abstract

The present invention provides a Doppler flow measuring device, comprising a radar component, a pan-tilt platform connected to the radar component, a mounting platform connected to the pan-tilt platform, and a mounting platform fixing member for fixing the mounting platform relative to a carrier of the flow measuring device. The radar component monitors the flow velocity of a water body by sending and receiving radio wave data, and further comprises a locking member, a locking position corresponding to the locking member, and a button component. Any one of the locking member and the locking position is arranged on the mounting platform, and the other is arranged on the mounting platform fixing member. The locking member contacts an elastic element and the elastic force of the elastic element is used to make the locking member cooperate with the locking position. A force-bearing part is arranged on the locking member, a pressing part is arranged at one end of the button component, and a pushing part contacting the force-bearing part is arranged at the other end. The pressing part is pressed to drive the force-bearing part through the pushing part so that the locking member overcomes the elastic force of the elastic element.
