Underwater stoplog gate pushing stabilizing device

The invention belongs to the technical field of still water underwater gate closing construction, and particularly relates to an underwater stoplog gate pushing stabilizing device which comprises an outer frame. A stoplog gate body is mounted on the side wall of the outer frame; a plurality of stand columns are fixedly connected to the side wall of the outer frame. The stand columns are evenly distributed on the side wall of the outer frame and are of the same structure. When the stoplog gate body is pushed to move, the fixing block can slide on the side wall of the stand column, dirt attached to the side wall of the stand column can be shoveled off, the situation that the stoplog gate body is prone to shaking due to the impact of water flow during moving can be reduced, and at the moment, under the cooperation of the stand column and the fixing block, the stability of pushing the stoplog gate body to move is improved; the accuracy of inserting the stoplog gate body into the gate groove is improved, meanwhile
