Blocking device for preventing sediment deposition in river irrigation
The invention relates to the technical field of river irrigation, in particular to a blocking device for preventing sediment deposition in river irrigation. The blocking device comprises a blocking box, wherein a through circulation opening is formed in the blocking box, a fixing frame is fixedly connected to one side wall of the circulation opening, two sealing baffles are hinged to one end of the fixing frame, and reset springs are fixedly connected between the ends, close to each other, of the sealing baffles and the side walls, away from each other, of the circulation opening. According to the blocking device, a large amount of silt in a river is directly blocked to prevent the silt from entering a farmland or a reservoir when the river is irrigated, meanwhile, death of crops is avoided, riverbed rising is reduced due to blocking of the silt in the river, and when too much silt is deposited in the river, the deposited silt is cleaned and discharged in time, so that the situation that the silt carried in river water in river irrigation is irrigated into the farmland to bury root systems of crops is greatly reduced, and the farmland is prevented from being silted or dead.
本发明涉及河流灌溉技术领域，特别涉及一种用于河流灌溉防止泥沙淤积的阻挡装置，包括阻挡箱，所述阻挡箱内设有贯通的流通口，所述流通口一侧壁上固连有固定架，所述固定架一端铰接有两个密封挡板，所述密封挡板相互靠近一端与所述流通口相互远离侧壁之间固连有复位弹簧，本发明通过对河流中的大量进行直接阻挡防止泥沙在河流灌溉时进入农田或水库，同时避免了农作物的死亡，而对河流中泥沙的阻挡也降低了河床的升高，且当河流中的泥沙淤积过多时及时将淤积的泥沙进行清理排出从而大量减少了河流灌溉中河水中夹带的泥沙灌溉入农田而掩埋农作物根系同时避免农田淤废或死亡。
