Description

The vertical formula of hitting of low head small water flow whirlpool directly drives high efficiency water generating outfit

Technical field the utility model relates to energy complete sets of equipment, and specifically the vertical formula of hitting of a kind of low head small water flow whirlpool directly drives high efficiency water generating outfit.

Background technique is along with the exhaustion of global energy, and the raising of living standards of the people, electric power energy demand increases sharply year by year.Thermoelectricity, nuclear power bring huge social enviroment protection problem, and the serious natural disaster such as " environmental pollution, ecological failure, global warming, Melting Glaciers: " is day by day serious.Development of clean energy utilizes will become the common concerned issue in the whole world, realize saving Resources, developing a circular economy, walk resource regeneration, build economizing type harmonious society, energy-conserving and environment-protective of benefiting the nation and the people.Meanwhile, along with globalization of world economy, clean energy resource industry is inevitable to specialized Road Development.But domestic or be not also utilized effectively at small river low head water level in the world at present, allow its favourable resource waste, actual is that innovation not large on equipment breaks through, and is mostly parked in traditional old stuff equipment, can not walk out traditional old stuff equipment forbidden zone, restriction small power station advances and development.What at home and abroad generally adopt at present is scroll casing type, tilt-impulse type but they there is adopted process engineering and equipment has the shortcomings such as cost is high, energy consumption large, installation foundation construction cost is high, water flow is large, drop is high, complex process, labor intensity are large, efficiency is low, device maintenance cost is high, service cycle is long, seriously hinder the effective full use rate both at home and abroad to river basin water resource, waste favourable precious resources.

Model utility content

The purpose of this utility model overcomes above-mentioned Problems existing, the vertical formula of hitting of a kind of low head small water flow whirlpool is provided directly to drive high efficiency water generating outfit, for river basin low head water resource efficiency utilization is laid a good foundation, in raising generating efficiency, effect is more obvious especially.

The utility model is that the low head small water flow whirlpool realized like this hangs down that directly to drive high efficiency water generating outfit be by horn mouth to formula of hitting, whirlpool water conservancy diversion spiral, lower water-jet mouth, back taper fairing body, streamlined interior isolation housing, major diameter water impeller, major diameter water impeller rotor and inside and outside water-ring thereof, inside and outside major diameter water impeller rotor, water holding ring rises seal ring, major diameter water impeller power transmission shaft, transmission shaft spring bearing, coupling, generator, excitation electromotor, Operation and Maintenance platform forms, upper horn mouth is arranged on the top of back taper fairing body, the waterpower pressure in whole housing directly can be increased after filled with water, water flows at enclosure interior top-down, it is vortex-like that water forms whirlpool one by the whirlpool water conservancy diversion spiral in housing water water conservancy diversion in funnel while flowing from the top down, in body, to form circinate current, to have flow velocity fast, impact force is large.Whirlpool water conservancy diversion spiral is mounted between back taper fairing body and streamlined interior isolation housing, and form one and up big and down smallly form an impartial spacing around back taper fairing inwall, namely this whirlpool water conservancy diversion spiral lower end head is water-jet mouth.Lower water-jet mouth and major diameter water impeller install so that less matching gap is corresponding, from the bourn acting force that whirlpool water conservancy diversion spiral is rotated down, is vertical impact blade plane substantially, so waterpower utilization rate is brought up to ultimate attainment.In order to ensure not waste water resource, spy is outside equipped with water impeller rotor and inside and outside water-ring thereof in water impeller, and inside and outside water impeller, between water holding ring and back taper fairing body and streamlined interior isolation housing, be provided with ring rise seal ring, guarantee that the current of back taper fairing body and streamlined interior isolation housing do not leak, play fine effect to saving water resource.Major diameter water impeller is directly connected with water impeller power transmission shaft, and the rotary torsion in the future to major diameter water impeller passes to generator rotary electrification through spring bearing coupling rotary torsion.Generator is fixed on streamlined interior isolation housing tip, forms certain altitude with the water surface in upper horn mouth, to ensure that generator is not operationally made moist or water logging.Excitation electromotor is then connected with generator coaxle, and while generator operation, excitation electromotor is to rotate with generator simultaneously simultaneously.Conveniently to the operation and maintenance of a whole set of generator, the Operation and Maintenance platform of a spaciousness is installed around streamlined interior isolation housing tip, convenient to generator enforcement examination and maintenance.This outfit water is flowing in swirling in engine housing, have that water flow rotary speed is fast, water can produce back taper siphonage from top to bottom in engine housing, back taper fairing body upper end is the same flow guide structure bodies of inverted cone shape loudspeaker in addition, not only water produces without hindrance swirl flow at upper horn mouth but also can also increase the hydraulic pressure pressure of water in whole funnel, effectively improves utilization ratio and the turbine efficiency of water.

Vast territory and abundant resources in China, and natural resources is very abundant, and river basin is innumerable, if having the water resource of certain drop effectively to be utilized in river basin, this is a huge natural resources wealth.Small water flow water generating is the clean energy resource of very environmental protection, apply very extensive, the low head small water flow whirlpool formula of hitting of hanging down directly drives the application of the applicable any complicated geographical small river of high efficiency water generating outfit, there is compact integral structure, easy for installation, structure simple, the large generating efficiency of failure rate is low, torsion is high, without the need to fill, without the need to installing honeycomb duct, not destroying original riverbed structure and planting standby, be the great new breakthrough of Chinese small water flow power field, there is certain economic benefit and social benefit.
