Water conservancy project rapid desilting device with stirring function

The invention provides a water conservancy project rapid desilting device with a stirring function. The water conservancy project rapid desilting device comprises a floating structure, auxiliary structures are hinged to the bottoms of the two sides of the floating structure, the bottom of the floating structure is connected with the mounting structure, an expanding structure is mounted at the bottom of the mounting structure, a transmission structure is arranged at the front end of the expansion structure, a stirring structure is mounted on the transmission structure, and a collecting structure is fixed to the rear side of the expanding structure. A sludge collecting structure and a stirring structure are mounted on the bottom plate, so that the bottom plate is connected to the bottom of the mounting plate through four sets of connecting rods, meanwhile the connecting rods and the bottom plate form a parallelogram structure, therefore, the drooping bottom plate can be always in a structure parallel to the mounting plate, each group of connecting rods are arranged to be of a telescopic structure, the bottom plate can extend into a deeper water surface, and the desilting work is completed.
