Abstract
The utility model relates to a kind of drainage for abrupt slope high water head, belongs to Hydraulic and Hydro-Power Engineering facility field.The utility model comprises upstream collecting-tank, and upstream collecting-tank has upstream water inlet, upstream delivery port, and upstream delivery port is connected with pressure pipeline, is provided with decompressor in pressure pipeline.When the utility model is implemented, ditch-water is imported in the collecting-tank of upstream, is then discharged by pressure pipeline, owing to being provided with decompressor in pressure pipeline, to reduce pressure step by step energy dissipating along journey, thus make ditch-water can safe and effective excretion in river course or other passage.In addition, pressure pipeline can be arranged along the gradient with the shortest distance, does not affect by terrain slope.
Description
Technical field
The utility model relates to a kind of drainage for abrupt slope high water head, belongs to Hydraulic and Hydro-Power Engineering facility field.
Background technology
Along with country is to the demand of water power clean energy resource, building a large amount of high dams, for ensureing work area safety and environmental beauty demand, surface water near work area need be drained into safely in river course or in other passage in order.According to current design criteria specification, or be protection power station main structures safety, ditch-water cleanup standard requires strict, when drainage grade is larger, limits by site contour, and ditch-water is let out row's Dissipation of Energy and given prominence to.Adopt conventional gutter pattern, gutter and neighbouring surface infrastructure fragile, can not meet the demands.
Utility model content
Technical problem to be solved in the utility model is: the drainage for abrupt slope high water head providing a kind of use safety.
The technical scheme adopted for solving the problems of the technologies described above the utility model is: for the drainage of abrupt slope high water head, comprise upstream collecting-tank, upstream collecting-tank has upstream water inlet, upstream delivery port, and upstream delivery port is connected with pressure pipeline, is provided with decompressor in pressure pipeline.
Further: the end of pressure pipeline is connected with downstream absorption basin, downstream absorption basin has downstream water inlet, downstream delivery port, downstream water inlet, downstream delivery port are located at downstream absorption basin respectively in the two side be oppositely arranged, and bottom the absorption basin of downstream, delivery port front, downstream are provided with water-blocking bank.
Further: upstream water inlet, upstream delivery port are located at upstream collecting-tank respectively in the two side be oppositely arranged, and upstream water inlet is located at the upper end of its side wall, and upstream delivery port is located at the lower end of its side wall.
Further: upstream collecting-tank is provided with in delivery port front, upstream and blocks dirty device.
Further: bottom pressure pipeline, be provided with bracing or strutting arrangement.
The beneficial effects of the utility model are: during enforcement, ditch-water is imported in the collecting-tank of upstream, then discharged by pressure pipeline, owing to being provided with decompressor in pressure pipeline, to reduce pressure step by step energy dissipating along journey, thus make ditch-water can safe and effective excretion in river course or other passage.In addition, pressure pipeline can be arranged along the gradient with the shortest distance, does not affect by terrain slope.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1-upstream collecting-tank, 11-upstream water inlet, 12-upstream delivery port, 2-pressure pipeline, 3-decompressor 4-downstream absorption basin, 41-downstream water inlet, 42-downstream delivery port, 5-water-blocking bank, 6-block dirty device, 7-bracing or strutting arrangement.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises upstream collecting-tank 1, and upstream collecting-tank 1 has upstream water inlet 11, upstream delivery port 12, and upstream delivery port 12 is connected with pressure pipeline 2, is provided with decompressor 3 in pressure pipeline 2.
The quantity of decompressor 3 and specification can be arranged as required, during enforcement, are imported by ditch-water in upstream collecting-tank 1, then discharged by pressure pipeline 2, owing to being provided with decompressor 3 in pressure pipeline 2, to reduce pressure step by step energy dissipating along journey, thus make ditch-water can safe and effective excretion in river course or other passage.In addition, pressure pipeline 2 can be arranged along the gradient with the shortest distance, does not affect by terrain slope.
Preferably, the end of pressure pipeline 2 is connected with downstream absorption basin 4, downstream absorption basin 4 has downstream water inlet 41, downstream delivery port 42, downstream water inlet 41, downstream delivery port 42 are located at downstream absorption basin 4 respectively in the two side be oppositely arranged, and bottom downstream absorption basin 4, downstream delivery port 42 front are provided with water-blocking bank 5.Ditch-water is by after the pressure pipeline 2 that arranges decompressor 3, although most of energy is eliminated, but still have portion of energy at pressure pipeline 2 end, at its end, downstream absorption basin 4 is set, when pressure pipeline 2 end current enter downstream absorption basin 4, utilize water-blocking bank 5 to form certain depth water cushion, utilize this water cushion to carry out last energy dissipating, ditch-water energy after downstream absorption basin 4 is eliminated substantially completely, makes that ditch-water is relatively smooth-going enters downstream row ditch.
Preferably, upstream water inlet 11, upstream delivery port 12 are located at upstream collecting-tank 1 respectively in the two side be oppositely arranged, and upstream water inlet 11 is located at the upper end of its side wall, and upstream delivery port 12 is located at the lower end of its side wall.Adopt this structure, the foreign material such as silt can be made in ditch-water to fall to upstream collecting-tank 1 in order, avoid retaining pressure pipeline 2 and be convenient to cleaning, in addition, can ensure that pressure pipeline 2 has been in pressure condition, avoid occurring that negative pressure affects pressure pipeline 2 safety.
Preferably, upstream collecting-tank 1 is provided with in upstream delivery port 12 front and blocks dirty device 6, avoids floating pollutant to enter blocking pipe in pressure pipeline 2.
Preferably, bracing or strutting arrangement 7 is provided with bottom pressure pipeline 2.Effectively to be connected, to ensure the stability of pressure pipeline 2 with domatic by bracing or strutting arrangement 7.
