[0036] When a flow measuring device that relies on a truss-assisted current meter is in use, it is necessary to first use the screw and the cooperation of the first clamping plate and the second clamping plate to ensure the stable clamping of the suspension rod. Then, operate the first slider to slide on the first slide rail to adjust the lateral position of the device in the bridge body until the predetermined flow measurement position is reached. Use a winch to operate the retraction and release of the connecting rope, control the sliding of the second slider on the second slide rail, and adjust the longitudinal position of the device in the bridge body to ensure that the suspension rod can accurately reach the measurement section. When the bottom of the suspension rod is lowered to the water flow section, the flow velocity can be measured by the speed meter bound to the suspension rod. After the measurement is completed, operate the winch to raise the suspension rod, and move it to the next flow measurement position to repeat the above operation. After the flow measurement at all positions is completed, push the horizontal pulley block back to the initial position, loosen the fixation, take out the flow measuring suspension rod and the flow meter, and complete the flow measurement. Afterwards, the staff can open the snap plate and rotate the first mounting plate to facilitate the operation of the suspension rod. The device can make the suspension rod move up, down, left and right easily. It is highly practical and safe, and can be widely used in flow measurement work similar to bridge erection sections.
