Riverway water flow velocity monitoring device

Abstract

The invention discloses a riverway water flow velocity monitoring device. The device comprises a measuring rod, a fixing device and a triangular baffle; a signal converter is arranged at the upper endof the measuring rod; a wire is arranged at one side of the signal converter; a counter is arranged at the lower end of the wire; a water temperature measuring device is arranged above the fixing device; a sonar is arranged on the outer surface of the measuring rod; a rotating device is arranged to one side of a signal transmitter; and a tail wing is arranged at one side of the fixing device. Theriverway water flow velocity monitoring device of the invention is provided with an anti-scratching film, the triangular baffle and the water temperature measuring device; and therefore, the surfaceof a display screen can be prevented from be scratched after being used for a long time, and therefore, the definition of the display screen is protected; the impact force of water flow on the measuring rod can be reduced, the measuring rod is effectively protected, and the service life of the measuring rod is greatly prolonged; and therefore, the riverway water flow velocity monitoring device iseconomically efficient and practical, can measure the water temperature of a water area, and has a bright use prospect.

Description

technical field [0001] The invention relates to the field of water flow velocity detection devices, in particular to a monitoring device for river water flow velocity. Background technique [0002] The flow meter is a flow meter made by applying the principle of the acoustic Doppler effect. It uses an ultrasonic transducer to detect the flow velocity with ultrasonic waves. The measurement point is in front of the probe, without destroying the flow field. It has high measurement accuracy and wide range. It can measure weak or strong flow, high resolution, fast response, can measure instantaneous flow velocity and average flow velocity, and can measure linearity , the flow rate verification curve is not easy to change, there are no mechanical rotating parts, there is no problem of sediment clogging and aquatic weed entanglement; the probe is durable, not easy to damage, and easy to operate, etc. The current meter is a device for measuring the flow rate of water in pipes, chann...

AI Technical Summary

Problems solved by technology

[0003] The existing water flow rate detection device has certain disadvantages in use. First, after a long time of use on the display screen, the surface is prone to scratches, which affects the clarity of the display screen and is not convenient for people to view the data. Secondly, it cannot reduce the water flow to the measurement. The impact force of the rod makes it difficult to provide effective protection for it, cannot prolong the service life of the measuring rod, cannot measure the water temperature of the water area at the same time, and cannot measure the depth of the water area, which brings certain adverse effects during use. , we propose a monitoring device for river flow velocity
