The invention provides an
underwater walking dredging device, and belongs to desludging devices. The
underwater walking dredging device comprises a device body which is a closed shell, and a
sludge inlet is formed in the bottom of the closed shell. Two gridding type drive belts are symmetrically arranged on the outer wall of the body, and the gridding type drive belts are driven through a
drive shaft. A driving mechanism and a
sludge pump are arranged in the device body, and the driving mechanism is connected with a driving shaft. The
sludge pump is connected with a sludge conveying
pipe, and the upper end of the sludge conveying
pipe extends out of the device body. A
control table is further included, and the
control table is electrically connected with the driving mechanism and the sludge pump respectively through lines. The
underwater walking dredging device is simple in structure, reasonable in design, widely applicable to desludging of ponds, reservoirs and city moats, capable of achieving quickness and high efficiency, low in
energy consumption and ceaseless in operation. Water in the ponds does not need to be swabbed off, blockage can not happen, the sludge swabbing concentration is high, and good practicability is achieved.
