Siphoning type reservoir desilting and screening device and use method thereof

Abstract

The invention discloses a siphoning type reservoir desilting and screening device and a use method of the siphoning type reservoir desilting and screening device. The siphoning type reservoir desilting and screening device comprises a swinging and stirring mud sucking nozzle, a mud sucking state sensor, a water power depositing material screening device and the like. A row of anchor blocks which are vertical to the axis of a dam are arranged on an upstream dam slope, a dam top and a downstream dam slope of the reservoir dam. Water sucking pipes and mud sucking pipes are installed on the anchor blocks in parallel. Mud sucking hoses are loaded on a row of floating boats on the water surface of the water reservoir. The mud sucking state sensor is arranged on the suspended ceiling part of a derrick mast of the head of a powerboat, a steel wire rope penetrates through a fixed pulley which is connected with the mud sucking state sensor to lift and sink the swinging and stirring mud sucking nozzle to the sediment deposit layer at the bottom of the water reservoir. A water power depositing material screening device, a material field, a depositing pool, a water diversion sluice and a water diversion canal are arranged at the foot of the downstream dam. The siphon principle is used by the siphoning type reservoir desilting and screening device to perform desilting on a reservoir zone, power is provided for the depositing material screening device and the screened sand and gravel materials are used as construction materials. Water is introduced into the canal for irrigation. The siphoning type reservoir desilting and screening device can reasonably utilize water resources and protect the water environment.

Description

technical field [0001] The invention relates to equipment for dredging reservoirs and screening sediment materials, in particular to a siphon type reservoir dredging and screening equipment and its application method. Background technique [0002] At present, the bottom hole reserved by the dam is often used for dredging. Since the position of the water inlet of the bottom hole of the dam is fixed and the water flow is concentrated, only the sediment near the water inlet of the bottom hole can be removed, and the dredging of the entire reservoir area is basically ineffective. , Some reservoirs have affected the water storage capacity and power generation, and because the height of the outlet of the dam bottom hole is low, the cleared silt is directly discharged to the downstream river, causing blockage of the downstream river. Contents of the invention [0003] Aiming at the current situation that reservoirs are seriously silted and the dredging effect of the dam bottom ho...

Problems solved by technology

[0003] Aiming at the current situation that reservoirs are seriously silted and the dredging effect of the dam bottom hole is not ideal, the present invention proposes a siphon type reservoir dredging and screening equipment and its use method, which can dynamically dredge the reservoir area, and utilize With the power provided by the siphon water flow, the siphoned silt material is hydraulically screened at the downstream dam foot, the screened gravel material is used as building materials, and the settled water is introduced into the channel for irrigation and other purposes.
