Description
Technical field
The invention belongs to water conservancy machinery technical field, particularly relate to the reservoir dredging device for removing a kind of zero carbon emission of shoal materials in reservoir and using method thereof.
Background technology
Existing reservoir majority was built in the sixties in 20th century 50, lacked the design of effective sand discharge, silting phenomenon generally occurs, seriously reduce the utilizable capacity of reservoir after running for many years. Reservoir sediment accumulation makes reservoir capacity reduce, and reduces water-holding capacity, particularly the Northwest, and Fluvial sediment amount is big, is even completely lost reservoir function by the reservoir of Sediment Siltation. Although Design of Reservoirs has bottom hole for sand flushing, but can only be drained by the silt near mouth door, and big flow sand discharge waste water resource.
The major way discharging bottom of the reservior shoal materials is adopted to have at present: one is be allowed to dry desilting, and winter reduces water level, and the silt surfaced is transported by slag-soil truck, spends amount transport expense; Two is adopt hydraulic desilting, utilizes the energy of big flow to be discharged from reservoir bottom hole for sand flushing by silt in flood period, the water resource that waste is valuable; Three is underwater desilting, by suction dredge tool, hyper-concentration flow is transported to sedimentation tank, and clear water returns reservoir, and mud uses slag-soil truck to transport; Four is that underwater desilting row is become silted up integrated, utilizes pressure current or vacuum-flow that by sediment delivery pipe, the silt that strand is inhaled is discharged reservoir. First three mode has formed industry in popularization and application, but power consumption is big, efficiency is low, and the 4th kind of mode makes full use of reservoir dam upstream and downstream pressure differential, is discharged by hyper-concentration flow outside storehouse, for energy-efficient measure, in studying and improving.
Reservoir desilting is used mostly strand and inhales machinery, use diesel engine strand to inhale bottom of the reservior silt, and by High-power Mud Pump and pipeline sediment to bank or mining under reservoir. This dredging method needs the significantly high energy, and the power of dredger is typically in more than 500KW, 500KW diesel engine oil consumption 130 liters per hour, had both consumed the energy, and had also polluted air.
Selectivity reservoir automatic dredging system, the patent No. 201320577368, in dam flood discharge sluice gate to reservoir, water main is installed, its length is as the criterion with volume of reservoir, water main connects some silt-sucking tubes, every silt-sucking tube sets some silt dredging mouths, Magnetic valves and variable force buoy is set in water main stage casing, after sluice is opened, water in reservoir enters silt dredging mouth due to hydraulic pressure, silt gravel is mixed in water also into silt dredging mouth, water and silt gravel enter silt-sucking tube and enter again water main, flow out further through flood discharge sluice gate, silt gravel near silt dredging mouth and silt-sucking tube is because being sucked away and physical features step-down, the silt gravel of eminence can flow to lower again about, go round and begin again, the silt gravel of reservoir bottom and cleaned reduce to optimum state, simultaneously can according to hydraulic pressure, by Magnetic valves and variable force buoy, variable force buoy buoyancy can be promoted open Magnetic valves or reduce variable force buoy buoyancy closedown Magnetic valves, segmentation silt dredging. this design wants emptying reservoir to lay pipe network, and the density of pipe network silt dredging mouth is bad to be determined, the suction of silt dredging mouth is little, and depositing the mud hardened for many years cannot discharge, and dredging effect is not good.
The deficiencies in the prior art how are overcome to become when one of emphasis difficult problem urgently to be resolved hurrily in water conservancy machinery technical field.
