Each water turbine generator is installed respectively on a reinforced concrete base arranged in a downward staircase pattern. A protection hood is equipped above each water turbine generator. These protection hoods are also arranged in a downward staircase pattern and connected together successively. The water turbine generators distribute electricity through a circumscribing device on the protection hoods. The high efficiency generating device can fully utilize surplus water energy of the hydraulic power station to lash multistage water turbine generators for power generation which multiplexes the generation efficiency, alleviates the shortage of electricity, and increase the economical benefit of the hydraulic power station.

Description

Power station water can efficient generating apparatus

Technical field

The utility model relates to a kind of TRT, specifically is the device that the power station utilizes the multistage generating of water energy.

Background technology

The power station is to utilize barrage to build a dam water level is improved, drop is very big between the water of high water level and low water stage, the glassware for drinking water of eminence has very big energy, water is toward dirty when not impacting hydrogenerator, some potential energy is converted into kinetic energy, should follow law of conservation of energy theoretically, the total energy of this circulating water is still equal with the total energy when high water level.After electricity has only been sent out once with the water slug hydrogenerator in the power station at present, water can be flowed away in vain, in fact used up energy of hydrogenerator of water slug is less, is the part of water energy, and this moment, water still had very big potential energy and kinetic energy.At present, this part dump energy is not fully utilized.

Summary of the invention

In order to overcome the shortcoming that prior art exists, the purpose of this utility model provides a kind of water energy that can make full use of the power station, impacts multistage hydrogenerator generating, improves the utilization rate of water energy, alleviate the pressure of electricity, the water that improves economic benefit of hydropower sta can efficient multistage power generating device.

The technical solution adopted in the utility model is: power station water can comprise that mainly the dykes and dams of each lock hole delivery port of power station are provided with a hydrogenerator by efficient multistage power generating device; each lock hole water flow discharging direction of dam is equipped with one group of multistage stepped hydraulic generator unit of arranging step by step downwards; every all corresponding respectively being installed on the stepped downward step by step reinforced concrete plinth of hydrogenerator; every hydrogenerator top is covered with protective cover; protective cover is also stepped to link to each other downwards step by step successively, and hydrogenerator is outwards carried electric energy by the external device on the protective cover.Each hydraulic generator unit comprises 2-12 hydrogenerator, every hydrogenerator installation interval 3-10 rice.

The utility model compared with prior art has the following advantages:

1, can improve the stability of dam, make it firmer, more stable, safer.

2, make full use of power station surplus water energy, improve water can utilization rate, can multiple former same power station several times electric weight, increase economic efficiency, alleviate the shortage of electric power situation, save electric coal.

3, save cost, as long as suitably increase some infrastructure and generating equipment, other all can be shared with first order generator.

4, utilize water-energy generating electricity more, use coal power generation less, reduce and pollute, the protection environment is saved natural resource.

Among Fig. 1,2,3, first order hydrogenerator 1, second level hydrogenerator 2, third level hydrogenerator 3, fourth stage hydrogenerator 4,5, the six grades of hydrogenerators 6 of level V hydrogenerator, lock hole 7, dykes and dams 8, reinforced concrete plinth 9, protective cover 10.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is elaborated.

Power station water as shown in Figure 1, 2, 3 is multistage power generating device efficiently; the dykes and dams 8 of each lock hole 7 delivery port of power station are provided with a hydrogenerator 1; correspondence is equipped with 2-12 hydrogenerator and stepped arrangement downwards step by step on the reinforced concrete plinth 9 of each lock hole water flow discharging direction of dam; every hydrogenerator top is covered with protective cover 10; protective cover is also stepped to link to each other downwards step by step successively, and hydrogenerator is outwards carried electric energy by the external device on the protective cover.This multistage power generating device is applicable to the old and new power station, when newly-built, directly design multistage power generating device, and multistage generating can be reconstructed in dry season or appropriate time in existing power station, thereby reaches object of energy saving.

As shown in Figure 1, 2, water is flowed out from dam lock hole by high water level and impacts the hydrogenerator generating, and we are referred to as the one-level generating; Water still has very big drop when dirty, and water can be still very big, still can be used to promote the hydrogenerator generating, is referred to as the secondary generating; In like manner, water continues still to can be used to generating toward the dirty energy that still has, and is referred to as three grades of generatings; The rest may be inferred, and level Four, Pyatyi, six grades of generatings etc. can be arranged.The water of each grade can be all slightly a little less than the first order, and then the generated energy of each grade also lacks than the first order, although lack than the first order, if generated energy addition at different levels, the total electric weight that obtains is several times of the first order.As first order energy and generated energy are decided to be 1.0, below the energy and the generated energy of each grade all be that 80% of upper level (is assumed to be 80%, but actual value not necessarily 80%), then partial generated energy is 0.8, and the third level is 0.64, and the fourth stage is 0.512, level V is 0.496, the 6th grade is 0.3968, and the gross generation of 1-6 level is 3.8448, just 3.8448 of the first order times.So, can make full use of dump energy with this multistage power generating device generating, make the generating efficiency multiplication, the generated energy in a power station can support several generated energy with the scale original hydro-power station, and economic benefit also increases several times.What TRT a power station specifically can build, and decide according to the drop of this station water.Below 50 meters, can build 4-5 level TRT as drop, many meters of 50-100, just can build one-level TRT every more than 10 meters as drop, many can build 10 multistage power generating devices.Notice between every two-stage generator that distance is not too near, anti-sealing remains in a standstill, and influence the flow velocity of water, influence the upper level generating, but also too not far away, too far waste water can, water can be not fully utilized, and lacks to generate electricity and influence benefit.Multistage generating is the same with the principle that Upper Yangtze River Jinsha jiang River section is built a plurality of power stations, all be that the drop that utilizes water, the energy of water generate electricity, only same power station water can be by multistage generator for electricity generation, the nearly water drop of standoff distance is smaller between the generators at different levels, and the distance water drop is more bigger between the adjacent power station, and its essence, principle all are the same.
