Description
Technical field
The utility model relates to ecological water area view field, specifically a kind of overflow dam being applicable to scenic rivers.
Background technology
In the exploitation and control of scenic rivers, because scenic rivers mostly is the form of stagnant water, along with high temperature evaporation or infiltrate soil and need constantly to inject new water in scenic rivers to keep the water yield and the vigor of scenic rivers, and when reservoir is in Landscape River during water filling, because the water yield is difficult to the problem of control and reservoir height, so often cause current exceed the dam crest of overflow dam thus form backflow, the efficiency that makes to discharge water subtracts greatly.
Summary of the invention
The utility model, for overcoming the deficiencies in the prior art, designs a kind of overflow dam that effectively can reduce head backflow probability, to improve the efficiency discharged water.
For achieving the above object, design a kind of overflow dam being applicable to scenic rivers, comprise dam body, lower dam body, gate, sensor, is characterized in that: the right flank of described lower dam body is circular arc, and the bottom of lower dam body right flank is horizontal, be provided with dam body above lower dam body, be provided with gate between lower dam body and upper dam body, the upper dam body be positioned at above gate is provided with floodgate motor, the left side of upper dam body and lower dam body is provided with reservoir, and the left side being positioned at the upper dam body on the right side of reservoir is provided with sensor.
The right flank of described lower dam body is provided with another sensor.
The utility model compared with the existing technology, has novel structure, simple, practical, feature convenient to use; Effectively can delay the probability reducing head backflow, thus the efficiency that lifting reservoir discharges water.
Accompanying drawing explanation
Fig. 1 is elevation of the present utility model.
See Fig. 1, wherein, 1 is reservoir, and 2 is sensors, and 3 is upper dam bodys, and 4 is floodgate motor, and 5 is gates, and 6 is lower dam bodys, and 7 is another sensors.
Detailed description of the invention
With reference to the accompanying drawings the utility model is described further below.
As shown in Figure 1, the right flank of described lower dam body 6 is circular arc, and the bottom of lower dam body 6 right flank is horizontal, dam body 3 is provided with above lower dam body 6, gate 5 is provided with between lower dam body 6 and upper dam body 3, the upper dam body 3 be positioned at above gate 5 is provided with floodgate motor 4, and the left side of upper dam body 3 and lower dam body 6 is provided with reservoir 1, and the left side being positioned at the upper dam body 3 on the right side of reservoir 1 is provided with sensor 2.
The right flank of described lower dam body 6 is provided with another sensor 7.
When the utility model uses, when the water yield in reservoir 1 reaches sensor 2 height be positioned on the left of upper dam body 3, for preventing the water in reservoir 1 from overflowing, floodgate motor 4 regulating gate 5 is upwards packed up, and opens a sluice gate and draws out some water; When the water yield in river course be positioned on the right side of lower dam body 6 another sensor less than 7 time, the water shortage in river course is described, floodgate motor 4 regulating gate 5 is upwards packed up, and opens a sluice gate and draws out some water equally, to keep the abundance of river water.
