Description
Technical field
The utility model belongs to hydraulic structure water conservancy diversion sluicing technical field, and specifically relating to a kind ofly provides down the structure of letting out ecological flow for reservoir initial filling.
Background technology
In recent years along with China's improving constantly Hydraulic and Hydro-Power Engineering environmental protection requirement, letting out ecological flow problem under during reservoir engineering first filling is the emphasis that environmental protection authorities pay close attention to.Method conventional at present has following several:
(1) hole and electric butterfly valve are set on water conservancy diversion outlet structure escape works steel-slag sand, or open regulating gate aperture to let out the object of ecological flow under reaching by import steel-slag sand local.In view of electric butterfly valve does not have successful engineering experience, plate steel gate is opened and is easily made gate produce vibration under river channels, and technical risk is large, is difficult to the requirement meeting downstream ecology flow;
(2) during retaining, some water pumps are set before dam, from the dewatering orifice of drawing water before dam to the certain elevation of dam body.This scheme uses more in small reservoir, but some engineering dam height are large, exceeded the water lift lift of water pump, adopts the method to be difficult to meet downstream water demand requirement.
Utility model content
For solving the problem, the utility model provides a kind of and provides down the structure of letting out ecological flow for reservoir initial filling.Just can meet downstream water supply requirement without the need to local starting gate during making lower lock, implement convenient and easy.
The utility model is achieved by following technical solution.
A kind ofly provide down the structure of letting out ecological flow for reservoir initial filling, comprise permanent water retaining structure and be arranged at the water conservancy diversion outlet structure escape works above permanent water retaining structure, be provided with permanent outlet structure escape works in described permanent water retaining structure, be provided with interim water pond, reservoir area in permanent water retaining structure upstream.
Further, the aqueduct to permanent water retaining structure downstream water supply is provided with below the interim water in described reservoir area pond.
Further, interim Shui Po top, described reservoir area is provided with pumping equipment.
Further, described pumping equipment is suction pump.
Further, interim water pond, described reservoir area is built up before lock under water conservancy diversion outlet structure escape works, and stores full water.
Further, the interim water in described reservoir area pond is positioned at permanent water retaining structure upstream 100 ~ 500m scope.
The beneficial effects of the utility model are:
Have employed described in the utility model under let out ecological flow structure, when before lock under diversion structure, utilize the retaining of water pond.When after lock under water conservancy diversion outlet structure escape works, the a little aquaporins being from upstream to downstream are blocked by gate, when needs are to downstream water supply, lift gate is not needed again to discharge water, and only need to utilize conduit pipe to flow automatically or with pumping for water pump, by conduit pipe to downstream water supply, diversion or the flow that draws water determine according to downstream ecology uninterrupted.Adopt the utility model, the startup repeatedly avoiding gate is closed, and can reduce gate running cost, improves gate application life, guarantees that engineering is at the security and stability building period simultaneously.When permanent water retaining structure is retained to permanent outlet structure escape works elevation, change and provide downstream ecology flow by permanent outlet structure escape works.Realize artesian diversion owing to utilizing reservoir area interim water pond retaining or draw water to permanent water retaining structure downstream, avoiding that cause when adopting water pump not enough from pumping head before permanent water retaining structure dam cannot to the problem of downstream water supply.The utility model technical risk is little, simple for structure, convenient and practical, with low cost, can play the effect arrived very much, and can not leave over lower defect to permanent building self, can in hydraulic structure water conservancy diversion sluicing technical field wide popularization and application.
Accompanying drawing explanation
Fig. 1 is layout schematic diagram of the present utility model;
Fig. 2 is that structural profile of the present utility model arranges schematic diagram.
In figure: 1-water conservancy diversion outlet structure escape works, interim water pond, 2-reservoir area, the permanent water retaining structure of 3-, the permanent outlet structure escape works of 4-, 5-suction pump, 6-aqueduct.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, described in the utility model 1, a kind ofly provide down the structure of letting out ecological flow for reservoir initial filling, the water conservancy diversion outlet structure escape works 1 comprising permanent water retaining structure 3 and be arranged at above permanent water retaining structure 3, described permanent water retaining structure 3 is provided with permanent outlet structure escape works 4, permanent water retaining structure 3 upstream is provided with interim water pond 2, reservoir area.
The aqueduct 6 to permanent water retaining structure 3 downstream water supply is provided with below interim water pond, described reservoir area 2.Aqueduct 6 for from reservoir area interim water pond 2 artesian diversion to permanent water retaining structure 3 downstream.
Top, interim water pond 2, described reservoir area is provided with pumping equipment.
Described pumping equipment is suction pump 5.Drawn water to permanent water retaining structure 3 downstream by suction pump 5.
Interim water pond 2, described reservoir area is built up before water conservancy diversion outlet structure escape works 1 time lock, and stores full water.
Interim water pond, described reservoir area 2 is positioned at upstream, permanent water retaining structure 3 upstream 100 ~ 500m scope.Make to flow automatically by aqueduct 6 or utilize water pump 5 to draw water to permanent water retaining structure 3 downstream.
Interim for reservoir area water pond 2 in use, before water conservancy diversion outlet structure escape works 1 time lock, is stored full water by the utility model in advance, and unnecessary interim water pond 2, Shui Zecong district top overflow, to meet reservoir filling requirement.After water conservancy diversion outlet structure escape works 1 time lock, utilize suction pump 5 to draw water interim water pond 2 from reservoir area, and cause permanent water retaining structure 3 downstream by aqueduct 6, realize to downstream water supply.
As can be seen from Figure 1, permanent outlet structure escape works 4 to be arranged within permanent water retaining structure 3 or outside, when permanent water retaining structure 3 is Rigid Dam, then permanent outlet structure escape works 4 are generally sand duct, flood discharge mesopore, diversion tunnel or overflow surface bay etc.; And when forever water retaining structure 3 is flexible dam, then permanent outlet structure escape works 4 are generally flood discharging tunnel, emptying tunnel, diversion tunnel or flood spillway.
When the utility model is implemented, interim water pond, reservoir area 2 is a short harmony dam, and be positioned at permanent water retaining structure 3 upstream certain distance, build up before diversion structure 1 time lock retaining and store full water, unnecessary water is then from the overflow of Shui Po top.After water conservancy diversion outlet structure escape works 1 time lock, the diversion passage of upstream toward downstream is blocked, and when needs supply certain water yield to downstream, utilizes aqueduct 6 from water pond artesian diversion or passes through pumping for water pump.Enter permanent water retaining structure reservoir area from the water of water pond 2 top overflow, reservoir starts retaining.When permanent water retaining structure 3 retains water to permanent outlet structure escape works 4 elevation, provide downstream ecology flow by these permanent outlet structure escape works 4.
