Task of the present invention has been come like this, a kind of water-power plant, comprise be implemented on river, upstream for tackling and raising the check dam of the water level in river, upstream, one hydrogenerator and concentration of energy device hydrogenerator being generated electricity for the water in river, the upstream of being tackled by check dam is caused hydrogenerator being arranged on downstream, wherein: the delivery port of hydrogenerator communicates with downstream river, be characterised in that: described concentration of energy device is an energy collecting tube, one end of this energy collecting tube is connected with the water inlet of check dam and communicates, and the other end of energy collecting tube is connected with described hydrogenerator.
In a specific embodiment of the present invention, described river, upstream is natural river.
In another specific embodiment of the present invention, be provided with floating thing trashrack for tackling floating thing at described checkdam towards the side in river, described upstream and corresponding to the position of described water inlet.
In another specific embodiment of the present invention, on described check dam and corresponding to position between described water inlet and described energy collecting tube, be provided with gate.
In another specific embodiment of the present invention, the position between described delivery port and described downstream river is being provided with Ji Shachi.
Also have in a specific embodiment of the present invention, described energy collecting tube is provided with stack, and the upper end of this stack exceeds the horizontal plane in river, described upstream.
More of the present invention and in a specific embodiment, described energy collecting tube is straight tube or the bend pipe being configured with crest and trough.
In an of the present invention and then specific embodiment, described energy collecting tube is concrete reinforced pipe or prefabricated metal pipe.
Of the present invention again more and in a specific embodiment, when described energy collecting tube is straight tube, the gradient is >=0.5%; And when energy collecting tube is the bend pipe with crest and trough, the maximum height difference distance between crest and described water inlet is≤8 meters.
In an again of the present invention and then specific embodiment, on described energy collecting tube and along the length direction of energy collecting tube, space state is provided with stretching device.
Technical scheme provided by the invention, owing to have employed the concentration of energy device taken on by energy collecting tube between the check dam that builds on river, upstream and the hydrogenerator being arranged on downstream river place, thus there is following strong point: one, good and farmland mountain forest and cities and towns, village can not be undermined to topography and geomorphology compliance; Its two, be applicable to the natural river water system with larger drop; Its three, construction cost is low and can meet requirement of generating electricity by way of merging two or more grid systems nearby; Its four, can investment reduction with economize on resources; Its five, because energy collecting tube 4 is tending towards non-maintaining, thus can embody good relatively cheap effect.
