Abstract
The present invention relates to a step-shaped hydraulic power station. It includes a first generator units and several generator units which are successively positioned after said first generator unit. The described all the generator units are successively connected by means of water runway and distributed according to the stepped mode, and between adjacent generator units a correspondent water storage pond is set, the water inlet of generator unit positioned in the front of water storage pond and water outlet of generator unit positioned in the rear of water storage pond are respectively communicated with the described water storage pond by means of respective pipeline.
Description
Technical field
The present invention relates to a kind of stepped hydraulic electrogenerating station, be suitable for various hydroelectric generation occasions, particularly be applicable to middle-size and small-size water-power plant with a varied topography.
Background technology
Existing water-power plant generally is to build a dam through stream on ground to intercept water raising head, and the drop by water changes potential energy into kinetic energy, the pushing generator generating.The defective in this power station is to have only the one-level generating set, and the water outlet of this generating set often also has higher flow velocity, not only causes energy dissipation, but also makes at the bottom of the dam and the riverbed is subjected to greater impact.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of stepped hydraulic electrogenerating station, this power station can make full use of the energy of water, and reduce current to the dam at the bottom of and the impact in riverbed.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of stepped hydraulic electrogenerating station, comprise first generating set, also comprise the some grades of generating sets of postorder that are positioned at the first generating set back, described generating sets at different levels connect by water stream channel successively, and staged distributes.
Can be provided with corresponding reservoir between the described part or all of adjacent generating set, be positioned at the reservoir front generating set water inlet and be positioned at the back generating set delivery port respectively the pipeline by separately be communicated with described reservoir, constitute the described water stream channel between these two generating sets thus.
Beneficial effect of the present invention is: owing to be provided with multistage generating set by step-wise manner, the water outlet of previous stage becomes the water inlet of back one-level, has made full use of the energy of water, has avoided energy dissipation; Since afterbody to go out water flow velocity very low, reduced impact at the bottom of the dam and riverbed, avoided spending more the construction cost of expense for bearing greater impact; Because the basis and the reservoir basis of a plurality of generating sets can be interconnected to form an integral body with key dam, have improved whole steadiness, have improved the application life of the bearing capacity and the whole structure of key dam, and help reducing the key dam investment; Because the spilling water of key dam can be accepted and hold to the reservoir of back level, helps flood control, particularly when war takes place, can not cause the flood disaster because of key dam is destroyed; Because each generating set can work alone, help each unit shutdown maintenance respectively, particularly still can normal power generation in the unit fault or when being destroyed; Because the utilization of Water Energy is abundant, also help the whole supply that improves the energy, alleviate the energy shortage state; In addition, because the dam of generating sets at different levels can make full use of landform, be distributed on the different height above sea levels along the footpath flow path direction of water, the head that each dam accumulative total is formed is very big, and needn't build a very high dam for forming big head, help saving construction cost.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing, the invention provides a kind of stepped hydraulic electrogenerating station, comprise first generating set 3, comprise also being positioned at first generating set some grades of generating sets of postorder 5 afterwards that described generating sets at different levels connect by water stream channel successively, and staged distributes.
Can be provided with corresponding reservoir 6 between the described part or all of adjacent generating set, described reservoir is provided with and blocks water auxiliary dam 4, be positioned at the reservoir front generating set water inlet and be positioned at the reservoir back generating set delivery port respectively the pipeline by separately 7 be communicated with described reservoir, constitute the described water stream channel between these two generating sets thus.Do not establish under the situation of reservoir between part or all of adjacent generating set, the water inlet that the generating set delivery port that is positioned at the front is located on the generating set of back directly is communicated with by pipeline, constitutes the described water stream channel between these two generating sets thus.
The present invention is provided with key dam 1, and described key dam is provided with the water inlet pipeline 2 of first generating set, and the key dam head promotes the generating of first generating set by the water inlet pipeline of described first generating set.
Can also be provided with some key dam branch pipe(tube)s 10 on the described key dam, coupling part or whole described reservoirs particularly connect the reservoir between first generating set and second generating set respectively.Described each key dam branch pipe(tube) is provided with shutoff valve, so that control the break-make of branch pipe(tube) separately.
Between described each reservoir, between the particularly adjacent reservoir, also can be provided with branch pipe(tube) 9 between the pond of direct connection two reservoirs, also be provided with shutoff valve on the branch pipe(tube) between described each pond.The setting of branch pipe(tube) between described key dam branch pipe(tube) and pond can make current flow directly into the reservoir of back when the part generating set damages or keep in repair, and promotes the generating set generating of back, still can generate electricity on the whole to guarantee the power station.
Described each pipeline (for example branch pipe(tube) between the connecting pipe between the water inlet pipeline of first generating set, each key dam branch pipe(tube), each generating set intake-outlet, each pond) all can be a circular pipe, to reduce resistance.
The two ends of the water inlet pipeline of described first generating set can be respectively equipped with shutoff valve, are used for damming when this generating set is shut down, and make water pass through the key dam branch pipe(tube) through stream.
The import of branch pipe(tube) can be arranged on the bottom of the reservoir of its connection between described each pond.
The trapezoidal profile mode of the sum of series generating sets at different levels of described generating set can be provided with flexibly according to landform.
The delivery port of described the last grade generating set generally can adopt the open type delivery port, and water is inserted the river course, can also be provided with one or more generating sets 8 that push away on the river course of its back, and the kinetic energy of water is fully utilized.Described horizontal sliding generating set can adopt prior art, for example No. 87202707 disclosed floatation type water-power plants of patent of invention of China.
Staged distribution of the present invention is meant that the height of the generating set mounting plane of back is lower than the height of the generating set mounting plane of front, and the horizontal range between each adjacent generating set can be different with difference in height.
