Drainage device for inland river mud barge

The drainage device for the inland river mud barge is used for being installed in a mud barge cabin and comprises fixing blocks, a filter plate and a water suction pump which are installed in the mud barge cabin, the fixing blocks are installed on the inner wall of the mud barge cabin at intervals to form an installation clamping groove, and the filter plate is inserted into the installation clamping groove to form a filter cavity with the mud barge cabin. And the water suction pump is arranged in the filtering cavity. The fixing blocks are arranged in the mud barge cabin to form the mounting clamping groove, the filter plate can be quickly mounted through the design of the mounting clamping groove, sludge in the mud barge cabin can be dehydrated under the action of the filter plate, water in the filter cavity can be quickly pumped by the water suction pump after dehydration, and the water suction efficiency is improved. And meanwhile, due to the design of any drainage pipe in the sludge barge cabin, the dehy
