Abstract

The invention discloses a blade hydraulic turbine that builds half dam on the river to collect flow and generate. Wherein, said half dam is little higher than the level in dry season; it can avoid closing two dams, while mounting blade hydraulic turbine between two half dams, to collect the water flow and improve the water level. Wherein, the blade hydraulic turbine is at the middle of water flow, with stable flowing speed; therefore, its property will not change in flood season, to confirm the continuous operation. Several blade hydraulic turbines are operated on one horizontal axle inside the cylinder tube, to improve the flow utilization most; said half dam (steel bar concrete dam) (as picture B) is mounted with escape channel and generator at its middle; the invention can obtains table water energy, without destroy plants.

Description

The half dam type afflux generator set

Technical field:

A kind of hydraulic generator unit is a kind of half dam type afflux generator set of development and use renewable nature (advection) water energy specifically.

Background technique:

Existing hydroelectric water turbine must possess high head, and the water storage of need building a dam, hoarding energy, water storage are built a dam will the heavy damage natural, ecological! , the construction in large-scale water power plant, it is serious more to destroy natural, ecological; As the construction of Three Gorges Dam, invest huge, must be still waiting the time with mistake and do check wherein.Multinomial invention and model utility are open also having aspect development and use nature (advection) the water energy: novel as practicality: rivers floating type hydroturbine unit generation station,＜denomination of invention〉rivers floating type hydroturbine unit generation station or the like.

Summary of the invention:

The present invention also is a kind of exploitation of being based on nature (advection) water energy, promptly builds the half dykes and dams by utilizing on river, river, comes the impeller type turbine group of afflux generating.The half dykes and dams of indication: 1. from highly, it does not need height to build a dam only a little more than river, the river water level during dry season.2. it does not need two dams to close up, and the impeller type turbine group is installed in the middle of two half dykes and dams, and just the relative concentrated flow of energy is flooded, and the less not enough condition of water flow when remedying dry season is concentrated relatively and flooded.The middle firm installation impeller type turbine group of half dykes and dams is in the middle of the current oar blade type water wheels all the time, and flow velocity is more stable, need not to adjust the position of water wheels unit in the river, and can not be affected flood duration yet; Guarantee the continuous operations of water turbine.A plurality of oar blade type water wheels turn round on same horizontal axis, the raising of maximum limit water flow utilization; Escape way is set in the middle of the half (reinforced concrete dykes and dams) and generator set is installed, guarantee that promptly safety maintains easily again; Build the half dykes and dams obtain stable natural water can in, can not destroy natural vegetation again, make full use of the river, river nature (advection) water can promote the well-being of mankind, clothes close the theory that the focus development of advocating now utilizes renewable energy sources, have than practical meaning.

1. building the half dykes and dams must decide on actual conditions: low as locality water level in dry season, water surface broad just must be built the key dam (Fig. 1 .--A.B.C.) of half dykes and dams simultaneously; The water level that improves is concentrated on inferior dam (Fig. 1 .--a.); As locality water level height in dry season, the water surface is narrower, and the flow abundance of water is (as this class waters, Jinsha jiang River.) then only need the key dam (Fig. 1 .--A.B.C.) of build half dykes and dams just can make the running of impeller type turbine group.2. build cost for saving: the key dam of half dykes and dams (Fig. 1 .--A.C.): (only placing outside the reinforcing bar) at the position that connects impeller type turbine cylinder type pipeline, all the other are cyclopean concrete structure gravity dam, and (except that cement) all can gather materials on the spot; The slidably gate can close impeller type turbine group cylinder type pipeline (Fig. 1 .--7., 8.) is set in the dam.3. the key dam of half dykes and dams (Fig. 1 .--B.) is the reinforced concrete key dam, and power generating equipment (Fig. 2 .--5.) is installed in middle setting operation chamber.Escape way (Fig. 2 .--6.) is set, and the passway is positioned at more than the highest water level on records in this river, river.4. current are concentrated and are entered in the impeller type turbine group cylinder type pipeline by the splay Ba Kou of half dykes and dams, and (Fig. 1 .--1.) impacts the oar blade type water wheels one by one and rotate, and produces kinetic energy; By the conversion gear on the same axis (Fig. 1 .--2.), kinetic energy is passed to power generating equipment (Fig. 1 .--4.) (power generating equipment is made up of speed changer, flywheel, generator, conveying electricity equipment etc.) generating, and by escape way (Fig. 2 .--6.) output electric energy.5. impeller type turbine is simple in structure, and fabricating cost is low, does not need high sharp technology just can make; Wherein water wheels unit cylinder type pipeline can be used steel, and is also available reinforced concrete prefabricated.6. by setting operation chamber in the middle of the reinforced concrete key dam, escape way (Fig. 2 .--5,6.), sealing door and gate (Fig. 1 .--6.7.8.) slidably.Management maintenance is safe ready more.7. though advection water can not have " head ", the density of water is greater than the wind energy several times.8. machine operation equipment, machinery lubrication system etc. utilize existing communal technique just can be equipped with enforcement.9. it is exceedingly useful to resemble river, the river territory of this class of Jinsha jiang River for development and use.It can be developed alone, also can integrated scale: do not destroying natural ecological environment, pollution-free; Under the preceding topic of environmental protection, fully develop potential natural water energy, have everything to gain and nothing to lose, contributes to contemporary times and brings benefits for future centuries for it.
