Description

A kind of aqueduct is across reservoir point water intaking structure

Technical field

The utility model relates to hydraulic engineering field, in particular to a kind of achievable pipeline, reservoir coordination divide water, water intaking knot Structure.

Background technique

Water delivery, water diversion project directly affect the economic development and social stability in region, and engineering importance is self-evident.Closely Nian Lai, with the increase of demand, water delivery, water diversion project are increasing, and project scale is increasing, but engineering difficulty is then increasingly It is high.Many water diversion projects, which all exist, crosses road, bridge, and the problems such as across tunnel, river, some engineerings even will appear multilayer The phenomenon that intersection.Therefore, water delivery, water transfer channel, pipeline, pipeline etc. are designed and requires to be gradually increased with construction.

Reservoir is most important as its reasonable utilization of terminal in water delivery, water diversion project, and reservoir is put, stores, flow Size, the time of water storage and the control of water directly determine that upstream and downstream water requirement could be met the requirements.But, at present for Reservoir utilization in water delivery engineering is relatively single, the transfer for mostly only adjusting reservoir as downstream flow, to upland water Control, the utilization of extra water, the control of reservoir itself water the problems such as not can be carried out good regulation, this makes water delivery Reservoir utilization in engineering is relatively inefficient, fetches water, divides water, discharging capacity relative deficiency, influences the spirit of cooperative reservoir water dispatch Activity.

For this reason, it is necessary to propose a kind of aqueduct across reservoir point water intaking structure, which can realize water levels of upstream and downstream, water Effective control of amount, Reservoir Regulation ability is played as far as possible, and have good service ability.

Specific embodiment

For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates Detailed description are as follows for attached drawing:

As shown in attached Fig. 1 to Fig. 4, a kind of aqueduct is across reservoir point water intaking structure, including upstream water-supply-pipe 1, retaining weir 2, gushed on pipe 3, upstream row water pipe 4, overflow weir 5, upper gate 6, across reservoir pipeline 7, reservoir drainage pipe 8, downstream technology pipe 9, Aft-gate 10.The water inlet of the upstream water-supply-pipe 1 connects upper river, and for introducing upstream water body, the upstream is defeated Pipe 3 is gushed on the water outlet connection of water pipe 1 is described；The water outlet end of the upstream water-supply-pipe 1 and position is arranged in the retaining weir 2 The outside that pipe 3 is gushed on described, for raising the water body introduced from the upstream water-supply-pipe 1 upwards, into gushing pipe on described 3；The outside of the retaining weir 2 is arranged in the upstream row water pipe 4, for when water level is more than the retaining weir 2, water body can be by It is let out under the upstream row water pipe 4；The overflow weir 5 is arranged outside the upstream row water pipe 4, and the height of the overflow weir 5 is greater than The 2 top water body of retaining weir can be continued to raise by the height of the retaining weir 2, after water level is more than overflow weir 5, water Body can be let out under the outside by overflow weir 5 to reservoir；The water outlet of the upstream row water pipe 4 connects across the reservoir pipeline 7；The junction of the upstream row water pipe 4 and across reservoir pipeline 7 is arranged in the upper gate 6, for controlling discharge into water；Institute It states across reservoir pipeline 7 to pass through from reservoir bottom, for realizing water body leap；Described in the water outlet connection of across the reservoir pipeline 7 Downstream technology pipe 9；The setting of reservoir drainage pipe 8 connects the downstream in mining under reservoir, the water outlet of the reservoir drainage pipe 8 Water-supply-pipe 9；The junction of the reservoir drainage pipe 8 and the downstream technology pipe 9 is arranged in the aft-gate 10, for controlling Discharge into water；Above-mentioned each component is ultimately formed across reservoir point water intaking structure.

Above-mentioned aqueduct divides the water intaking, sluicing, dividing method for water of water intaking structure as follows across reservoir:

(1) when upstream cuts off the water, the upper gate 6 can be closed, water body is due to the retaining weir 2 is with overflow weir 5 It is lifted water level, realizes upstream Water-saving effect；Meanwhile the openable aft-gate 10, it is defeated that reservoir water body is introduced into the downstream Water pipe 9 realizes reservoir water intaking, as shown in Figure 3.

(2) when upland water, the openable upper gate 6 closes the aft-gate 10, upland water is introduced Across the reservoir pipeline 7 is eventually introduced the downstream technology pipe 9, as shown in Figure 2.In addition, can be by controlling the upper gate 6 apertures, and the overflow weir 5 is utilized, water body is introduced into reservoir, supplements reservoir water requirement.In addition, can also open simultaneously on described Gate 6 and the aft-gate 10 are swum, by upland water and reservoir water body while introducing the downstream technology pipe 9, realization pipeline, Reservoir joint water intaking, as shown in Figure 4.

(3) when upland water larger (that is, being greater than the set value), the openable upper gate 6 closes the downstream lock Door 10, water body can be met an urgent need by the overflow weir 5 and be sluiced in reservoir.

(4) when across reservoir pipeline 7 needs to overhaul, the openable aft-gate 10 closes the upper gate 6, will Upstream water body introduces the downstream technology pipe 9 by reservoir.

In the present embodiment, reservoir depth 20m, width 2km, 2 height 10m of retaining weir, 5 height 15m of overflow weir, each pipeline is straight Diameter 6m.

Although being described above in conjunction with preferred embodiment of the attached drawing to the utility model, the utility model is not It is confined to above-mentioned specific embodiment, the above mentioned embodiment is only schematical, is not restrictive, ability The those of ordinary skill in domain is not departing from the utility model aims and claimed under the enlightenment of the utility model Under ambit, many forms can also be made, these are belonged within the protection scope of the utility model.
