To solve this technical problem, the technical solution of the present invention is: a flow measuring device for an irregular river channel section, which includes a display terminal, a support frame, a cable and a sensor part, the support frame is arranged along the river channel, and the display The terminal is placed on the support frame, the display terminal is connected to the sensor part through a cable, the sensor part is located on the side of the river, and the support frame includes a first leg, a support platform, a bracket, and a second leg The connection plate, the displacement connecting strip and the second leg, the first leg has a round hole of the first leg, the second leg has a round hole of the second leg, and the first leg has a round hole of the second leg. The legs, the bracket and the support platform are an integral structure, the bracket is located at the top of the first leg, the support platform is located above the bracket, and the upper end of the second leg has a second Outrigger connection plate, the second outrigger connection plate is connected to the bracket, one end of the displacement connection strip is located in the waist hole of the second outrigger, the other end of the displacement connection strip is connected to the bracket Connected to the seat or located in the waist hole of the first leg.

A support bar is arranged between the bracket and the first leg, the lower end of the support bar is connected to the lower part of the first leg, and the upper end of the support bar is connected to the bracket.

A detachable waterproof cover is arranged on the support platform.

The flow measuring device for irregular river channel sections of the present invention adopts such a structure, which can quickly and accurately obtain hydrological test data, and can quickly collect flood flow data of rivers during major floods.
