Abstract

The utility model discloses a hydroturbine, which comprises a volute, a power output shaft arranged vertically on the top wall of the volute by a shaft bearing, a power output wheel arranged on the top part of the power output shaft, and an impeller arranged on the output shaft in the volute; a plurality of vane levers are fixedly connected on the impellers horizontally and evenly, and a vane with a concave structure is fixedly connected with the ends of the vane levers; a water inlet is arranged on the side wall of the volute at the height of the concave of the vane corresponding to the volute, and a drogue extending out of the volute is arranged at the water inlet. The utility model has the advantages that: the flowing water guided into the volute trough the water inlet form the outer channel evenly shocks the concave of the vane and drives the power output shaft to work. The drogue is arranged at the water inlet can change the flowing speed of the small flowing water, making the ejection of the flowing water at the water inlet form a shooting flow to achieve the required large energy; the arrangement of the concave of the vane makes the shock force of the flowing water more concentrated.

Description

The group hits the formula water turbine

Technical field

The utility model relates to hydroelectric generator, especially relates to a population and hits the formula water turbine.

Background technique

Water can be a kind of inexhaustible, nexhaustible clean energy resource, and hydroelectric power is to utilize river waterflow to do work from the potential energy that drop possessed that eminence flows to lower, promotes the water turbine rotation, drives generator for electricity generation.Hydroelectric power efficient height, environmental protection, cost of electricity-generating is low, and unit starting is fast, regulate easily, but because the structure of existing water turbine is primarily aimed at is to utilize natural flows, not only is subjected to effect of natural conditions bigger, needs artificial the build can the concentrated flow drop and regulate the hydraulic structure of water flow, as dam, diversion pipe culvert etc., construction investment is big, the construction period is long, and is subjected to the restriction of geographical water source environment, has directly influenced hydroelectric promotion and application.

The model utility content

The purpose of this utility model is to provide a kind of group simple in structure, that water usage is little, Applicable scope is wide to hit the formula water turbine.

For achieving the above object, the utility model can be taked following technical proposals:

Group described in the utility model hits the formula water turbine, comprise spiral case, be vertically set on the pto on the described spiral case roof and be arranged on the power output wheel on described pto top by bearing, and be set in place the impeller on spiral case internally-powered output shaft; Level is uniform on described impeller is fixed with many leaf arms, is fixed with the blade with concave structure in the end of described leaf arm; Corresponding concave surface height with described blade offers water intake on the sidewall of described spiral case, is provided with the Taper Pipe that extends outside spiral case in described water inlet.

Bearing sheath at described bearing is outside equipped with cooling jacket.

The concave surface of described blade is provided with towards the water intake direction.

Described Taper Pipe is a cellular structure.

After advantage of the present utility model was current are introduced spiral case from outside water channel by water intake, the concave surface that balancedly impacts described blade drove the pto acting.Because the water intake diameter can be offered according to the needed concrete tractive force of generator, so watt level is adjustable; Owing to the honeycomb Taper Pipe is installed in the water inlet, can change the flow velocity of small flow current, form jet to reach needed huge energy when making water inlet current ejection; Blade with concave structure makes impact force of water flow more concentrated, and the water turbine of this kind structure water usage when work is few, does not select geographical water condition, and every 10000KW unit water usage only needs 2.0m ³/ h, and the water source also can be recycled, and land is installed and need do not built a dam, and do not account for farmland and resettlement immigrant, short cost of investment low (only accounting for about the 1/15-1/18 of traditional cost) of duration is traditional hydro-electric power generating equipment update and the best substitute products that improve generate output; Outside the bearing sheath of described bearing, cooling jacket is set, can cools off the bearing that generates heat because of high speed rotating, prolong the working life of bearing.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

As shown in the figure, group described in the utility model hits the formula water turbine, comprise spiral case 1, be vertically set on pto 3 on described spiral case 1 roof by bearing 2, with the power output wheel 4 that is arranged on described pto 3 tops, and be set in place impeller 5 on spiral case 1 internally-powered output shaft 3; Level is uniform on described impeller 5 is fixed with many leaf arms 6, is fixed with the blade 7 with concave structure in the end of described leaf arm 6; Corresponding concave surface height with described blade 7 offers water intake 8 on the sidewall of described spiral case 1, and the concave surface of blade 7 is towards water intake 8 direction settings.Be provided with the Taper Pipe 9 of the cellular structure that outside spiral case 1, extends at described water intake 8 places.For making 2 coolings of described bearing, be outside equipped with cooling jacket 11 at the bearing sheath 10 of bearing 2.
