When detecting the flow in an open channel, the device The detection part is mostly installed in the open channel.

There is an existing ultrasonic open channel flow continuous measurement device (CN215893713U), which prevents the movement of the measuring frame by setting a fixed block, a limit block, a movable rod, a clamping rod and a clamping groove, so that the height of the measuring frame can be adjusted so as to measure the flow rate in the open channel. The effect of the flow of liquid at different heights. The measuring device is mainly fixed by inserting the movable rod into the bottom of the open channel. However, most of the open channels on the market are made of concrete. When dealing with concrete open channels, external equipment can only be used to drive the movable rod into the bottom of the open channel. Breaking the integrity of the bottom of the open channel leads to water leakage in the later stage of the open channel, and the movable rod will affect the flow direction and flow velocity of the water source in the open channel due to its own blocking, resulting in a decrease in measurement accuracy.

Detailed ways

Referring to Fig. 1, external ground nails can be penetrated through the bearing platform 1 and driven into the ground before use, so as to install the device on the bank next to the open channel. Compared with the prior art, the installation method beside the open channel is different It will affect the water flow in the open channel, so the accuracy of the open channel flow measurement is higher.

Referring to Figures 1-3, when needed, the two-way threaded rod 32 can be rotated, and the two moving blocks 33 shrink under the push of the thread, and the telescopic frame 42 drives the mounting frame 5 to extend forward through the hinged seat 41, so as to provide and change The use orientation of the ultrasonic detection head 6 can realize the measurement of any position in the open channel, which increases the applicability during use. When the ultrasonic detection head 6 reaches the use position, the threaded locking piece 34 can be screwed between the top of the column 31 The current position of the two-way threaded rod 32 can be fixed by the friction between the two. When detection is required, the ultrasonic detection head 6 detects the water flow in the open channel through the emitted ultrasonic waves, and at the same time transmits the signal The measuring instrument 7 is processed (the prior art), and the measuring instrument 7 can display the current water flow in the open channel in real time for the staff's reference.

Referring to Fig. 3-4, in the process that the telescopic frame 42 drives the installation frame 5 to expand and contract, the fixing frame 10 pulls the support member 11 to slide in the connecting frame 9 and the column 31, and when the installation frame 5 reaches the use position, it passes through the support member 11 The supporting properties of the telescopic frame 42 and the mounting frame 5 can be reinforced to prevent them from bending under the action of the wind.
