Background technology
Along with agricultural and industrial expansion, water resource is increasingly in short supply, and development high-efficiency water-saving technology is extremely urgent.In agricultural high-effiency water saving, conventional water source form is underground water, and at present, groundwater mining phenomenon is serious, and the high-efficiency water-saving technology greatly developed using surface water as water source will become the effective way of agricultural sustainable development.The husky separating difficulty of water in surface water is large, seriously constrains the promotion and application of the advanced high-efficiency water-saving technology such as spray, drip irrigation.
At present, taking surface water as the high-efficiency water-saving engineering measure at water source is: first surface water precipitates through traditional rectangular sedimentation tank; Spray, drip irrigation pipe network system is entered through filter after precipitation.During traditional horizontal sedimentation tank desilting, system generally will be stopped transport, and in sedimentation basin, clearing of silt is also a time-consuming job of spending, and constrains applying of high-new water-saving technology to a certain extent.
Summary of the invention
The purpose of this utility model is to provide a kind of bar shaped settling pit, and it is rational in infrastructure, and the husky separative efficiency of water is high, and cost is low, and operational management is convenient, and operating cost is low, dependable performance, and system failure rate is low, long service life, and waterpower erosion and deposition, during erosion and deposition, system is not stopped transport.
The purpose of this utility model is achieved in that sand discharge settling pit is contained at a kind of end controlled by the drowning pipe that can rise and fall, inlet channel is connected to bar shaped settling pit, the uniform board wall being provided with current stabilization hole on metope is set in the front portion of bar shaped settling pit, at the rear portion of bar shaped settling pit, fold-line-shaped downflow weir is set, conveyance canal is connected to after downflow weir, the uniform sand discharge that arranges is contained in the bottom of bar shaped settling pit, uniform respectively on the top board that every bar sand discharge is contained desilting strip hole is set, the cross section shape of desilting strip hole is top is V-type groove, the bottom of V-shaped groove is connected to hole, gap, coordinate in V-shaped groove and the drowning pipe that can rise and fall is installed, when drowning pipe sinks, hole, gap is closed, water (flow) direction in sand discharge culvert is contrary with the water (flow) direction in bar shaped settling pit, the sand discharge outlet that every bar sand discharge is contained is installed with sand discharge lock respectively.
Inlet channel of the present utility model is connected to bar shaped settling pit, and be provided with twice current stabilization orifice plate wall in bar shaped setting pot front portion, rear portion is provided with fold-line-shaped downflow weir, connects conveyance canal behind weir.Bottom in bar shaped settling pit is provided with several sand discharges and contains, in containing, water (flow) direction is contrary with water (flow) direction in pond, the outlet that sand discharge is contained is provided with the cast iron scouring sluice of rear sealing, and the top of culvert is provided with some desilting strip holes, coordinates and be installed with the drowning pipe that can rise and fall in the top V-shaped groove of desilting strip hole.
During utility model works, surface water enters bar shaped sedimentation basin by inlet channel, tended towards stability by the fluidised form in twice orifice plate current stabilization wall after-bay, gallery at the bottom of pond is entered by desilting strip hole when the silt of sedimentation is migrated at the bottom of pond, when needing to get rid of the silt in settling pit, open blowdown lock one by one, silt in corresponding gallery starts to migrate outside pond, drowning pipe above gallery in desilting strip hole automatically sinks to being closed in the hole, gap, bottom of desilting strip hole one by one under the effect of pressure reduction, reach sand discharge in the utility model system cloud gray model, the object that sand discharge efficiency is high.
After sand discharge lock cuts out, drowning pipe, under the effect of buoyancy, gets back to initial position, and the silt of migrating bottom settling pit enters sand discharge by desilting strip hole and contains.
Bar shaped settling pit trapezoidal cross-section designs, and structure is simple, and cheap, effect is visual, and operational management is convenient, and operating cost is low, dependable performance, and system failure rate is low, long service life.
The utility model is rational in infrastructure, and achieve the husky separative efficiency of water high, cost is low, and operational management is convenient, and operating cost is low, dependable performance, and system failure rate is low, long service life, and waterpower erosion and deposition, during sand discharge, system is not stopped transport.
