Description
Technical field
The utility model relates to water conservancy and hydropower apparatus field, particularly, relates to the layering water fetching device of a kind of dam formula water inlet.
Background technology
Along with Chinese society rapid development of economy, increasing to the demand of the energy, as reproducible clean energy resource, the proportion that the utilization of hydraulic power potentials accounts in energy development structure is more and more higher.At present planning and be huge or large hydropower station in the hydroelectric project of founding a capital, hostile environment impact is served in power plant construction and operation inevitably band.Power station is built up, after reservoir filling, its water level and water surface area all more natural situation increase considerably, often there is water temperature delamination phenomenon, generally show as: front reservoir area, dam in winter is tending towards isothermal and distributes, the more natural situation of lower sluicing temperature is high, and spring, summer, table water temperature in storehouse was high, and the more natural situation of lower sluicing temperature is low.Due to the requirement of intake of hydropower station depth of immersion, the position of the large storehouse of high dam water inlet is lower, operated by rotary motion is at the cold water layer (stagnant temperature layer) of reservoir, in power station high water level operation and table hole flood discharge chance little in the situation that, under let out water flow temperature to build natural river course water temperature before dam low, particularly step hydropower station low-temperature discharge stack cumulative effect, even can be lower 6～7 ℃ than natural river course water temperature, to downstream river course ecological environment, will affect greatly as agricultural irrigation, fish reproduction etc.
Water temperature Study on Problems is the emphasis of current large-scale power station ambient influnence research, according to the regulation of relevant laws and regulations, require research to adopt an effective measure and improve the lower temperature that sluices, and the problem that how to solve low-temperature discharge is difficult point and the key technical problem of current hydroelectric project design.Intake of hydropower station adopts stratified pumping facilities protection river ecological, is paid much attention at present in China, is just becoming the important engineering measure that solves some ecological problems in water resources and hydropower construction.
At present, stratified pumping is mainly used in the irrigation reservoir that scale is less, water temperature is had to requirement at home, to guarantee the growth of crops.The height of dam of these irrigation reservoirs is mostly lower than 40m, and layered water intake structures is mainly divided into two large classes: vertical shaft type and skewed culvert horizontal tube.Vertical shaft type adopts intake tower or gate shaft, vertically establishes some layers of gate, and by headstock gear open-close sluice gate, to control flow and water temperature, according to the difference of gate form, vertical shaft type is divided into again multi-layer planar gate and plate-turning door.Plate-turning door overhauls inconvenience, easily produces vibration, is used for small-sized irrigation reservoir, is not suitable for and has the large-sized deep water intake structure of adjusting, water temperature of reservoir layering for many years.Skewed culvert horizontal tube arranges water inlet along step inclined tube at different elevations, with cover plate plug, opens and closes.Generally, skewed culvert horizontal tube can only be applicable to the to fetch water degree of depth, reservoir that flow is less.
And water inlet is dam formula water inlet, compared with bank tower intake, dam formula water inlet rated head is lower, quotes flow larger.Adopt stratified pumping to have the problems such as water inlet leading edge is shorter, the cross-section of river is less, flow velocity is large, head loss is larger.
Utility model content
In order to address the above problem, the utility model provides the layering water fetching device of a kind of dam formula water inlet, particularly, adopts following technical scheme:
The layering water fetching device of a kind of dam formula water inlet, comprise the water inlet being arranged on dam body and the portal crane that is arranged on described water inlet dam crest, it is characterized in that, described water inlet both sides arrange respectively trashrack abutment pier, water inlet middle part arranges pier at least one trashrack, two gate grooves are set on pier in described trashrack abutment pier and trashrack, in two gate grooves, place respectively trashrack and Stoplog gate, described trashrack is arranged on the upstream end of Stoplog gate, described Stoplog gate comprises at least one joint single-unit Stoplog gate structure, single-unit Stoplog gate structure all connects portal crane, described trashrack connects portal crane.
Further, described water inlet does not arrange trashrack abutment pier near a side of abutment wall, twice are set are respectively used to place the grid groove of trashrack and Stoplog gate on described abutment wall.
Further, in described trashrack abutment pier and trashrack, the distance between pier equals the distance between pier in two trashracks.
Further, one group of crossbeam of horizontally set from top to bottom between described trashrack and Stoplog gate.
Further, the land side of described Stoplog gate arranges one group of brace summer from top to bottom, the vertical Stoplog gate setting of described brace summer.
Further, the structural shape of described Stoplog gate is planar slide gate.
Further, described single-unit Stoplog gate structure is connected with portal crane by mechanical grasping beam, and the top of described Stoplog gate arranges mechanical grasping beam alignment pin.
Further, the top of described Stoplog gate and bottom all arrange bearing plate.
Further, in described water inlet, along flow direction, set gradually import Emergency Gate and import step gate.
Further, on the dam body in described import step gate downstream, air vent is set.
Technical scheme before the utility model has adopted and has been different from, stratified pumping facility adopts Stoplog gate to carry out stratified pumping, utilize one Stoplog gate of the standby grid groove of trashrack setting, according to water temperature of reservoir, distribute and Reservoir Water Level situation, use dam crest portal crane to regulate Stoplog gate dash height, realize stratified pumping, in trashrack abutment pier and trashrack, the setting of pier can effectively reduce the span of trashrack.The utility model is simple, convenient, reliable, and water intaking high flexible is adjustable, is applicable to deep water large-scale intake structure, in addition, there is hydro-structure and arrange simply, hinge is arranged to impact is less, the advantages such as civilwork engineering quantity increases less, and construction investment relatively economizes, easy to maintenance.
