Abstract

The invention provides a river runoff measuring device. The river runoff measuring device comprises a frame body; a telescopic rod assembly, wherein the first end of the telescopic rod assembly is rotationally connected to the frame body, and the telescopic rod assembly comprises a first rod body and a second rod body; a guide part arranged on the telescopic rod assembly; a wire body, wherein the first end of the wire body is connected to the telescopic rod assembly; a driving assembly, wherein the second end of the wire body is arranged on the driving assembly; a measuring piece which is arranged on the driving assembly and used for measuring the length of the portion, extending out of the driving assembly, of the wire body; a range finder arranged on the frame body; and a flow meter arranged on the telescopic rod assembly. When the second end of the telescopic rod assembly abuts against the river bottom, the extension length of the wire body is measured through the measuring piece, so that the length of the side edge of a riverbed can be obtained, the width of a river bank is measured through the range finder, after the length of each edge of the inverted trapezoid is obtained, the sectional area of the riverbed can be calculated, and then the flow velocity of the river is measured through the flow meter. And the runoff of the river is obtained through the product of the sectional area of the riverbed and the flow velocity of the river.

Description

technical field [0001] The invention belongs to the technical field of measuring equipment, and in particular relates to a river runoff measuring device. Background technique [0002] The runoff of rivers entering the sea and the water quality of rivers are important values ​​for the amount of pollutants entering the sea. At present, the river runoff can only be calculated by estimating, and it is difficult to ensure the accuracy of the obtained results.
