本装置是一种通过水下阻力伞大截面拦截河水来获取动能,经牵引绳拖动的河流清淤装置。它能对河底的淤泥进行大面积的犁翻、搅混、往水面推等下、中、上三个层次顺水流连续工作,使河底的淤泥由静止状态变为漂流浮动状态而被河水带走,从而达到对河床清淤浚疏的目的。 This device is a kind of river dredging device which gets kinetic energy by intercepting river water through a large cross-section of underwater resistance umbrella and is towed by a pulling rope. It can plow the river silt for a large area, mixing, to push the water surface and so on, the middle and the upper three levels of continuous flow along the river, so that the bottom of the mud from the quiescent state into floating floating state by the river Go, so as to achieve the purpose of riverbed dredging Jun.
