Abstract
The utility model relates to an it stabilizes structure of sectional area to reduce surge -chamber. The utility model aims at providing an it stabilizes structure of sectional area to reduce surge -chamber is satisfying under the stable requirement, and it is lower to make every effort to simple structure, construction convenience, construction investment. The utility model provides a: an it stabilizes structure of sectional area to reduce surge -chamber, has many units of upstream side, and every unit is continuous with the bifurcated pipe of downstream side through respective tail water branch pipe, its characterized in that: each tail water branch pipe top between bifurcated pipe upstream side and unit all sets up a surge -chamber, and the bottom of every surge -chamber communicates with the tail water branch pipe that corresponds through the impedance hole. The utility model is suitable for a hydraulic and hydroelectric engineering, especially low -head hydroelectric plant.
Description
Technical field
The utility model relates to a kind of structure reducing Surge Chamber.Be applicable to Hydraulic and Hydro-Power Engineering, especially low-head hydroelectric plant.
Background technology
Current diversion or tail water discharge longer time in order to meet set steady safe operation, will surge-chamber be set; it is arranged on bifurcated pipe position usually; the value of Surge Chamber is one of key parameter guaranteeing stable operation of unit; in order to meet the requirement of stable operation of unit; Surge Chamber value is larger; add the difficulty of project playout on the one hand; add construction investment on the other hand; especially more remarkable for low-head hydroelectric plant, therefore reducing surge-chamber basal area is a good problem to study.
Summary of the invention
The technical problems to be solved in the utility model is: for above-mentioned Problems existing, provides a kind of structure reducing Surge Chamber, is meeting under stable requirement, makes every effort to that structure is simple, easy construction, construction investment be lower.
The technical scheme that the utility model adopts is: a kind of structure reducing Surge Chamber, there is the multiple stage unit of upstream side, every platform unit is connected with the bifurcated pipe in downstream through respective tail water arm, it is characterized in that: above each bar tail water arm between bifurcated pipe upstream side and unit, a surge-chamber is all set, and the bottom of each surge-chamber is communicated with corresponding tail water arm through impedance hole.
The beneficial effects of the utility model are: because the Set surge tank of this structure is on tail water arm, reduce the distance between surge-chamber and unit further, spiral case inlet maximum pressure (diversion surge-chamber) or draft tube import minimum pressure (down stream surge-chamber) can be improved; In addition, structure of the present utility model is simple, easy construction, can reduce surge-chamber scale, investment reduction.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Detailed description of the invention
As shown in Figure 1, the present embodiment reduces the structure of Surge Chamber, and have two units 5 of upstream side, every platform unit is connected with the bifurcated pipe 4 in downstream through respective tail water arm 2.In this example, surge-chamber 1 is arranged on tail water arm 2, namely above every bar tail water arm 2, arrange a surge-chamber 1, and the bottom of surge-chamber 1 is communicated with tail water arm 2 through impedance hole 3.
Through the postpone of said structure cloth, the waterhead fall of bifurcated pipe can contribute in the calculating of Surge Chamber and go, because the waterhead fall of bifurcated pipe is relatively large, usually about 0.5, after counting this coefficient, Surge Chamber can significantly reduce.
