Abstract
The utility model relates to a kind of pond and retaining dams syphon low-tension supply water replanishing device.The purpose of this utility model is, there is provided that a kind of structure is simple, cost is lower, the pond and retaining dams syphon low-tension supply water replanishing device of practical convenient, with solve syphon out of service for a long time after due to gas leakage causes cannot defeated water problem, guarantee that syphon is in office when can normally run by section, improves siphonal utilization rate.The technical solution of the utility model is: this water replanishing device comprises reservoir dam, reservoir and syphon, reservoir is positioned at reservoir dam back side bottom, syphon water inlet is positioned at reservoir dam upstream face bottom, syphon outfall is positioned at reservoir, siphonal outfall end arranges draining control valve, the top of the highest section of syphon height arranges header tank, and this header tank is communicated with the highest section of syphon through water-filling control valve, and header tank connects through filling pipe the submersible pump be placed in reservoir.The utility model is applicable to Hydraulic and Hydro-Power Engineering.
Description
Technical field
The utility model relates to a kind of pond and retaining dams syphon low-tension supply water replanishing device.Be applicable to Hydraulic and Hydro-Power Engineering.
Background technology
Syphon is a kind of pressure water pipe, general top curved and its elevation to supply water the water surface higher than upstream, due to the vacuum in syphon, pressure reduction is produced between the atmospheric pressure and siphon intraductal pressure of up-stream face, siphon principle is utilized to make current guide lower into by syphon highest point, so that flood discharge in flood season and emptying reservoir carry out safety inspection to engineering.Siphonal advantage is to cross over highland, reduces excavation, avoids the hidden leakage defect that calvert below dam is formed.
In prior art after syphon is out of service for a long time, gas leakage causes in pipe can not keep vacuum state, causes difficulty to reusing syphon.Usually solve this problem by using vacuum pump to bleed at present, cost is high, causes siphonal use to be limited to.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, there is provided that a kind of structure is simple, cost is lower, the pond and retaining dams syphon low-tension supply water replanishing device of practical convenient, with solve syphon out of service for a long time after due to gas leakage causes cannot defeated water problem, guarantee that syphon is in office when can normally run by section, improves siphonal utilization rate.
The technical scheme that the utility model adopts is: a kind of pond and retaining dams syphon low-tension supply water replanishing device, comprise reservoir dam, reservoir and syphon, reservoir is positioned at reservoir dam back side bottom, syphon water inlet is positioned at reservoir dam upstream face bottom, syphon outfall is positioned at reservoir, it is characterized in that: described siphonal outfall end arranges draining control valve, the top of described the highest section of syphon height arranges header tank, this header tank is communicated with the highest section of syphon through water-filling control valve, described header tank connects through filling pipe the submersible pump be placed in reservoir.
Described syphon outfall end latter end is bent into U-tube, outfall opening upwards.
The beneficial effects of the utility model are: the utility model arranges header tank, adopt low-tension supply moisturizing, be syphon moisturizing, guarantee syphon tunneling boring full water, solve in syphon running that cause cannot defeated water problem due to gas leakage, guarantee siphonal normal operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the present embodiment is a kind of pond and retaining dams syphon low-tension supply water replanishing device, and arrange reservoir 9 in reservoir dam 8 back side bottom, reservoir dam 8 is provided with syphon 1, this syphon 1 water inlet is positioned at reservoir dam upstream face bottom, and syphon outfall is positioned at reservoir 9.Outfall end at syphon 1 in the present embodiment arranges draining control valve 5, and above highly the highest section of syphon 1, arrange header tank 3, header tank is communicated with the highest section of syphon 1 by water-filling control valve 2.In this example, header tank 3 connects submersible pump 6 through filling pipe 4, and this submersible pump is placed in reservoir 9, utilizes low-tension supply to draw water in the header tank 3 at syphon 1 top, keeps header tank 3 water yield sufficient.Header tank 3 is connected by water-filling control valve 2 with syphon 1, and control valve is opened, and water in header tank 3 flows in syphon 1, and the air in syphon 1 is discharged, and can be in holding tube be so always full of water state when syphon 1 does not run.
Syphon 1 outfall end latter end is bent into U-tube 11, outfall opening upwards (being positioned at below the water surface), is beneficial to and utilizes water seal to prevent air from entering in syphon 1.
When syphon 1 normally runs, when the draining control valve 5 of syphon 1 outfall is opened, the water-filling control valve 2 between header tank 3 and syphon 1 is closed; When syphon 1 quits work, draining control valve 5 is closed, and opens the water-filling control valve 2 between header tank 3 and syphon 1, is injected in syphon 1 holding tube be like this in full water vacuum state by water body.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model is also not limited to above-mentioned citing; those skilled in the art; in scope of the present utility model, the change made, change add or replace, all should belong to protection domain of the present utility model.
