[0002] At present, in the hydrological detection of flow rate, flow velocity and so on at different positions of the river (in the height direction of the river and the width direction of the river), it is necessary to complete the detection work through the flow meter installed on the rod. When detecting at different positions, it is necessary to manually remove the flow meter and then install it at different heights of the rod, or translate the rod along the width of the river. When the flow meter is adjusted and installed before being used again, the position accuracy of the flow meter and the adjustment efficiency of the flow meter are low, which seriously affects the detection efficiency and effect. In addition, when encountering deeper waters, the rod is often short and needs to be lengthened manually. This can not only fail to ensure the firmness and stability of the rod after lengthening, but also affect the work efficiency. Utility Model Content
