Irregular river cross-section flow measurement device

Abstract

The invention discloses an irregular river cross-section flow measurement device. The device comprises a display terminal, a support frame, a cable and a sensor, the support frame is arranged along the bank of a river, the display terminal is arranged on the support frame, the display terminal is connected with the sensor through the cable, the sensor is located at the side of the river, the support frame comprises a first landing leg, a support platform, a bracket, a second landing leg connecting plate, a displacement connecting strip and a second landing leg, the first landing leg is provided with a first landing leg oval hole, the second landing leg is provided with a second landing leg oval hole, the first landing leg, the bracket and the support platform are of a integrally connectedstructure, one end of the displacement connecting strip is located in the second landing leg oval hole, and the other end of the displacement connecting strip is connected with the bracket or locatedin the first landing leg oval hole. According to the irregular river cross-section flow measurement device, hydrometry data can be rapidly and accurately obtained, and flood discharge data of the river can be collected rapidly in the great floods.

Description

technical field [0001] The invention relates to a measuring device, in particular to a flow measuring device for an irregular river channel section. Background technique [0002] In river hydrological testing, the measurement of flow velocity and flow is two very important tasks. The traditional flow testing methods mainly include the flow meter method, the buoy method, etc., and the testing methods include manual boat measurement, cableway measurement, etc. These testing methods The principle is simple and clear, and the practicability is strong, but it is labor-intensive, time-consuming, and inefficient. It is difficult to adapt to the needs of economic and social development and flood control work in the new era, and it is difficult to provide accurate hydrological information to flood control and drought relief departments at all levels in a timely manner. Especially during major floods, it is necessary to Rapid collection of river flood flow data is difficult to achieve...
