Blocking device for preventing sediment deposition in river irrigation

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of river irrigation, in particular to a blocking device for river irrigation to prevent sediment deposition. Background technique [0002] In general river irrigation, there is usually a large amount of sediment in the river water, and if the turbid sediment is deposited on the river bed, it will cause the river bed to rise, and if the large amount of sediment is not cleaned up in time and the farmland is irrigated, it will cause crops The root system of the soil is buried too deep by the sediment, which will cause the indirect death of the crops, and the deposition of the sediment will also cause the farmland irrigated by the river to silt or die, thus directly causing a large amount of economic losses. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a blocking device for river irrigation to prevent sediment deposition. [0004] The above ...
