Detailed Description

The present invention will be described in detail with reference to examples, but the present invention is not limited to these examples.

In water conservancy projects, the outlet of the confluence tank has relatively single requirement for supplying water to a far end, one confluence tank and one water level are used for determining the elevation of the bottom plate of the water supply outlet according to the relation between the water level and the type of the water supply outlet. However, in some engineering requirements, the confluence tank needs two different water levels for supplying water, and can be divided into two confluence tanks, and a part of water amount of the confluence tank with a high water level needs to overflow to the confluence tank with a low water level. The utility model discloses in, at first concentrate a big confluence pond with stranded inflow, adopt the weir body to control the pond and separate, carry out relatively accurate control to the right pond left pond the outflow of crossing water, and the operation management is comparatively convenient, reduces later stage running cost.

Specifically, the embodiment of the utility model provides a confluence pond structure of many exports, as shown in fig. 1 to 3, the confluence pond structure includes:

the confluence tank body.

The separation weir 3 is arranged in the confluence tank body and is used for separating the confluence tank body into a confluence right tank 1 and a confluence left tank 2; the water level of the confluence right tank 1 is higher than that of the confluence left tank 2. In practical applications, the separating weir 3 may be a thin-walled weir. Wherein, the thickness of the weir bottom of the thin-wall weir can be set to be 1-1.5 m; the thickness of the top of the thin-wall weir can be set to be 0.3-0.7 m, and is preferably 0.5m.

The utility model discloses adopt the thin wall weir to separate in the middle of the pond body that converges that will supply water the inconsistent elevation, during the incoming flow all got into right pond 1 that converges and the left pond 2 that converges, to controlling the inconsistency of pond water level elevation, adopt the thin wall weir to overflow to the split water and carry out the control of relative accuracy.
