The device comprises a first supporting rod and a second supportingrod, wherein one end of the first supporting rod is in threaded connection with one end of the second supporting rod, the other end of the first supporting rod is connected with a first supporting disc, the other end of the second supporting rod is connected with a second supporting disc, a sealed central control box is fixed on the first supporting rod, a data collector is fixed in the sealed central control box, a plurality of sensor fixing rods are connected with the second supporting rod, flow velocity sensors and water depth sensors are arranged on sensor fixing rods, and flow velocity sensors and water depth sensors are connected with a data collector through data wires.

Description

technical field [0001] The invention belongs to the technical field of flow measurement, and in particular relates to a drainage pipe and an open channel flow measurement device. Background technique [0002] Point source pollution and non-point source pollution are the main sources of river water pollution. Under the promotion of national environmental protection policies, various departments pay more and more attention to the control of pollutant discharge. Strict control of point source pollution discharge and effective monitoring of non-point source pollution discharge are formulated The non-point source control scheme is the key to improving the water environment. After the point source pollution has been effectively controlled, more and more attention has been paid to the non-point source pollution, especially the non-point source pollution caused by urban rainfall runoff has become the main source of urban river water pollution. [0003] In urban areas, pipelines and...

Problems solved by technology

With the development of technology, flowmeters using the Doppler principle can be used to measure the flow of partial pipes, but there are still some disadvantages: first, the above-mentioned principle flowmeter can only measure circular drainage pipes, and cannot measure the flow of open channels; secondly Most of the above-mentioned flowmeters are imported from abroad, which are expensive and have high maintenance costs in the later period, so it is difficult to apply them in a wide range; thirdly, the fluid in drainage pipes and open channels is a heterogeneous flow, and there are problems when measuring flowmeters based on ultrasonic or radio wave principles. Big error; Finally, the installation and power supply are complicated, and it is impossible to realize ready-to-use and dismantling
