The invention discloses a portable field surface river flow measuring device which comprises a floating body, a detection device, a liquid level detection device, a stability maintaining mechanism, a speed measuring device, a wireless transmission device and a ground base station, and the stability maintaining mechanism comprises a multi-section telescopic rod, an underwater electric push rod, a driving motor, a winding wheel and a load bearing piece. The detection device is mounted on the floating body, so that the cross section of the river channel can be detected; the data of the positions of the floating bodies at the n moments in the river measurement section are selected as samples, the average flow of the river in the measurement section is calculated, the average flow of the river in the measurement section serves as the flow of the river, measurement errors can be reduced, and the measurement precision is improved; by arranging the stability maintaining mechanism, the floating body can be more easily kept in a vertical state in water, and meanwhile the influence that the floating body is pushed by wind is reduced; the multi-section telescopic rod and the heavy piece can increase the contact area with water areas at different positions, and the flow measurement precision can be improved; obstacles can be avoided by driving the multi-section telescopic rod to contract and rotate.
本发明公开了一种便携式野外地表河流测流装置,包括浮体、探测装置、液位检测装置、维稳机构、测速装置、无线传输装置和地面基站,维稳机构包括多节伸缩杆、水下电动推杆、驱动电机、收卷轮、负重件。通过在浮体上安装探测装置,可对河道断面进行检测;通过在河流测量段选取n个时刻的浮体所在位置的数据作为样本,计算出测量段河流的平均流量,以测量段河流的平均流量作为河流的流量,可减少测量误差,提高测量精度;通过设置维稳机构,可使得浮体在水中更容易保持垂直状态,同时减低浮体被风推动的影响;多节伸缩杆和重件能够增加与不同位置水域的接触面积,可提高测流精度;通过驱动多节伸缩杆收缩和转动可进行避障。
