Dredging device for water conservancy projects
The invention discloses a desilting device for water conservancy projects. The desilting device comprises a motor, a rotating shaft and a stirring blade wheel arranged on the rotating shaft, a shaft sleeve is arranged on the stirring blade wheel, the outer end of the stirring blade wheel is sleeved with a protective net cover, the inner end of the protective net cover is arranged on the shaft sleeve, and stirring rods are arranged at the bottom end of the protective net cover; and a connecting block is arranged on the inner side of the bottom end of the protective net cover, a conical block is arranged at the lower end of the connecting block, a connecting mechanism is arranged between the connecting block and the conical block, and the conical block is located below the rotating shaft. Along with downward movement of the rotating shaft, the conical block preliminarily detects broken stone hard objects in a sludge layer, the stirring rods arranged below the protective net cover stir the sludge layer and stir the broken stone hard objects at the same time, then the stirring blade wheel finally stirs the sludge layer, the protective net cover outside the stirring blade wheel plays a good protection effect, the probability that the stirring blade wheel is collided and damaged is reduced, so that the stirring effect of the stirring blade wheel is improved.
本发明公开了一种用于水利工程的清淤装置，包括电机和转轴以及布设在其上的搅拌叶片轮，搅拌叶片轮上设置有轴套，搅拌叶片轮外端套设有防护网罩，防护网罩内端装设在轴套上，防护网罩底端布设有搅拌杆，且防护网罩底端内侧装设有衔接块，衔接块下端装设有锥形块，且衔接块与锥形块间设置有连接机构，锥形块位于转轴下方。随着转轴的下移，锥形块对淤泥层内的碎石硬物进行初步查探，布设在防护网罩下方的搅拌杆在对淤泥层进行搅拌的同时，也将碎石硬物搅拌开来，之后搅拌叶片轮对淤泥层进行最终搅拌，其外部的防护网罩起到较好的防护效果，降低搅拌叶片轮受到碰撞损伤的概率，从而提高了搅拌叶片轮的搅拌效果。
