Squirrel-cage type underwater pump hanging bracket
The invention belongs to a drag suction dredger, and particularly discloses a squirrel-cage underwater pump hanging bracket. The squirrel-cage type underwater pump hanging bracket is provided with a hollow cavity, the upper end of the hollow cavity is communicated with the outside through an opening part, a pump body can penetrate through the opening part to enter the hollow cavity, the two ends of the pump hanging bracket are the first pipeline connecting end and the second pipeline connecting end respectively, and the first pipeline connecting end and the second pipeline connecting end are both communicated with the hollow cavity. The front end of the pump hanger is a conical part, the outer diameter of the conical part is gradually increased from one end provided with the second pipeline connecting end to the other end, a plurality of hollow holes are formed in the outer wall of the conical part, and the outer diameter of the rear portion of the pump hanger body is gradually increased from the rear end to the middle. A gear box is omitted, the underwater pump is directly driven by the motor, the underwater pump hanging bracket adopts a hollow design and is similar to a mousetrap, the front and back conical design reduces water flow resistance, the self weight of the rake arm is reduced, meanwhile, the phenomenon of turbulent water flow during dredging is optimized, and the loading capacity of a single ship is increased under the condition that the dredging draft of the ship is designed to be fixed. By means of the design, the building cost of the ship is reduced, the use failure rate is reduced, the dredging efficiency is improved, and economic benefits are improved.
发明属于耙吸式挖泥船，具体公开鼠笼式水下泵吊架。鼠笼式水下泵吊架，其具有中空腔体，且中空腔体的上端通过开口部与外界相通，泵体能从开口部穿过进入中空腔体，泵吊架两端分别为第一管道连接端、第二管道连接端，第一管道连接端、第二管道连接端均与中空腔体连通，泵吊架前端为锥形部，锥形部外径自设有第二管道连接端一端至另一端外径逐渐增大，锥形部外壁开设有若干镂空孔，泵吊架本体后部自后端至中部外径逐渐增大。本发明省去齿轮箱，直接由电机驱动水下泵，水下泵吊架采用镂空设计，形似捕鼠笼，前后锥形设计减小水流阻力，不仅减少了耙臂自重，同时也优化了挖泥时水流乱流现象，船舶在设计挖泥吃水固定的情况下的单船装载量增加。该设计同时降低了船舶的建造成本，使用故障率降低，提升了挖泥效率，提高了经济效益。
