Description
Technical field
The utility model relates to priming device field, in particular to a kind of priming device of whole gravity flow.
Background technique
China is one of the country that river is most in the world, and water project is numerous, and some projects are designed into out water conservancy project
Journey, the forms such as water-supply method, the technology of use are more, than fetching water if any negative pressure drainage, siphon off water, radial water intaking etc.,
The many aspects such as investment cost, system performance, technology type can all have an impact entire engineering project, therefore, method for fetching water
It is most important.It in actual life, is formed and is catchmented using riverbed bottom, enter soakaway trench and infiltration pond by the filtering of sandstone layer by layer,
It is supplied water by conveyance conduit to water unit with water pump, since water pumping power operating cost improves；Simultaneously because silt and sundries
The reasons such as siltation, need manual maintenance, are existing deficiencies in the technology.
Utility model content
To solve the above problems, the utility model provides a kind of priming device of whole gravity flow, riverbed sundries can be filtered,
Can quick dredging at any time without pumping water resource guarantee water intake system performance.
The technical solution of the utility model is:
A kind of priming device of whole gravity flow, including riverbed, open up several water inlet lines, water inlet line in riverbed bottom
Port is provided with filter device；Connection sedimentation pipeline is collected in several water inlet line ends, and sedimentation pipeline is U-typed pipeline, " U "
One end connects water inlet line on type pipeline, and the other end connects outlet conduit, installs outlet valve at outlet conduit；U-typed pipeline bottom
Portion opens up blow-off line, installs blowdown valve at blow-off line.
Based on the above technical solution, the utility model can also do following improvement:
Further, the filter device is column, and upper and lower surface is sector, and the facade of filter device is equipped with filter opening, filtering
The acute ends of device are towards riverbed upstream.
Further, the water inlet height above sea level of the water inlet line is higher than outlet conduit ground water outlet.
Further, the riverbed upstream is higher than downstream, and blow-off line connects riverbed downstream.
Compared with the existing technology, the utility model has the following beneficial effects: riverbed bottom water passes through the mistake of filter device
After filter again through settle pipeline, can effective filtrating impurity in water, settle sandstone；Periodically open blowdown valve, sedimentation duct bottom sedimentation
Silt flows away as water flows through blow-off line, and dredging is convenient, saves a large amount of manpowers；Outlet valve is opened, after filtering sedimentation
Water can take, and without pumping, guarantee water intake system performance；Relative to large hydraulic engineering, project cost is reduced, reduces and builds
If large-scale dam shuts off to underground natural watercourse, reduces sewers produced by the large-scale dam of construction and the artificial calamity such as burst apart
Evil reduces reservoir ponding and floods the damage such as farmland.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model
Fig. 2 is filter device schematic diagram.
Specific embodiment
As shown in Figure 1 to Figure 2, the utility model is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, a kind of priming device of whole gravity flow, including riverbed 1, riverbed 1 is built without artificial, in riverbed 1
Bottom opens up several water inlet lines 3, and 3 port of water inlet line is provided with filter device 2；Collect several 3 ends of water inlet line
Connection sedimentation pipeline 4, sedimentation pipeline 4 is U-typed pipeline, and one end connects water inlet line 3 on U-typed pipeline, and the other end connects out
Waterpipe 5 installs outlet valve 7 at outlet conduit 5；U-typed duct bottom opens up blow-off line 6, installs blowdown at blow-off line 6
Valve 8.
River water takes out sundries by filter device 2 in 1 bottom of riverbed, and water inlet line 3 of entering collects into U-typed pipeline
4, it is settled in 4 bottom of U-typed pipeline, the river water after sedimentation facilitates ground staff to fetch water through 5 connecting pipe of outlet conduit, river
The silt of water sedimentation drains the silt of sedimentation, dredging is convenient as river water is by the outflow pipeline of blow-off line 6.
The water inlet height above sea level of water inlet line 3 is higher than the water outlet on 5 ground of outlet conduit, facilitates ground staff to fetch water and uses,
Water source is extracted using water pump without ground staff.
As shown in Fig. 2, filter device 2 is cylindricality, upper and lower surfaces are sectors, and the facade of filter device 2 is equipped with filter opening 201,
To filter sundries in river；For the acute ends of filter device 2 towards 1 updrift side of riverbed, river water washes away filter device 2, filtering dress
Setting 2 streamline rushes sundries to downstream along river, and acute ends can reduce river water to filter device towards 1 updrift side of riverbed
2 impact, arc end can increase the kick of filter device 2, be flushed away to avoid filter device 2.
1 upstream of riverbed is higher than downstream, and blow-off line 9 connects 1 downstream of riverbed, periodically opens blowdown valve 4, settles 3 bottom of pipeline
Portion settles silt as water flows through blow-off line 9, flow to riverbed downstream using the principle that The natural flow of water always proceeds from a higher level to a lower one.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
