Description
Technical field
The present invention relates to the long distance standard section gravity flow canal in hydraulic engineering, especially relate to long apart from standard section gravity flow canal increasing water delivery flow apparatus.
Technical background
Along with work, Water Consumption in Agriculture are increasing, supply deficiency because of water has seriously constrained the development of national economy, taking long apart from standard section gravity flow canal to regulate the watering balance between abundance of water region and lack of water region, is the important means that hydraulic engineering adopts.Apart from standard section gravity flow canal, water head site, due to the impact of natural objective condition, has wet season and dry season long, there is water level and to fluctuate up and down situation.When the water level of water head site is lower than design diversion position, even if the head gate full open state of gravity flow canal, its water diversion still also can decline.In addition, there is the situation affecting flow section water level by various factors interference along the line in gravity flow canal, the flow section water-level fluctuation etc. that the flow section water-level fluctuation that bleeder place, the canal stage casing head gate that such as flows automatically opens and closes the flow section water-level fluctuation caused, severe strong wind weather causes, rainstorm weather cause, gravity flow canal stage casing carrying capacity is declined relatively, and then causes the conveyance power of water in its downstream to decline.Above-mentioned condition can have a strong impact on the performance of project benefit, and especially the reduction of the long distance of ultra-large type, large discharge gravity flow canal diversion works conveyance power of water, will be huge on the impact of its social benefit.
Summary of the invention
The object of the invention is to provide a kind of long apart from standard section gravity flow canal increasing water delivery flow apparatus, to solve the problem of gravity flow canal water supply capacity deficiency when water level reduces, also can strengthen gravity flow canal water supply capacity in the water head site wet season.
For achieving the above object, the present invention takes following technical proposals:
Of the present invention long apart from standard section gravity flow canal increasing water delivery flow apparatus, comprise the turbine plug flow device be arranged on described gravity flow canal easy backwater section canal lower supporter, the delivery port of described turbine plug flow device is arranged towards Parallel to the flow direction, the housing two side of turbine plug flow device is symmetrical in its center line and is fixed with horizontal support arms respectively, described two horizontal support arms are plugged in upper shed locating slot corresponding on described canal lower supporter respectively; Be positioned at above turbine plug flow device and be provided with arched girder, described arched girder is fixed with the foundation pile being arranged on canal both sides of flowing automatically across above gravity flow canal, on arched girder, interval is hinged with connecting rod and telescopic hydraulic cylinder, a free bearing on the lower end of described connecting rod and turbine plug flow device housing is hinged, and piston rod end and the free bearing be fixed in the middle part of connecting rod of described telescopic hydraulic cylinder are hinged.
Described turbine plug flow device, canal lower supporter, connecting rod and telescopic hydraulic cylinder are be symmetrical in two covers that gravity flow canal center line is arranged side by side.
The work-pump station of described telescopic hydraulic cylinder and the frequency-conversion control cabinet of turbine plug flow device are arranged in gravity flow canal side on the bank.
The invention has the advantages that when occur along gravity flow canal section overcurrent water level height change inequality, cause declining along gravity flow canal backwater section conveyance power of water time, drop into the work of described turbine plug flow device, reach dredging channel water rate of flow of fluid and increase, realize maximum conveyance capacity.When turbine plug flow device runs, equipment pulls the plug, and rises and fixes with the arched girder be positioned at above turbine plug flow device, do not affect normal channel water stream flow regime when turbine plug flow device is out of service from water.
