Abstract
An energy saving hydraulic power generator mainly consists of an impulse water turbine and a correspondingly matching hydroelectric generator, and a tubular turbine and a correspondingly matching hydroelectric generator. The tubular turbine is located below a water outlet of the impulse water turbine. A water inlet of the tubular turbine is connected with the water outlet of the impulse water turbine. A main shaft of a rotating body of the tubular turbine is out of a tubular turbine housing and connected with a main shaft of a generator rotator of the tubular turbine by a mechanical transmission machinery. Compared with a single impulse water turbine, the energy saving hydraulic power generator of the utility model has the advantage of having a high conversion rate between water head kinetic energy and electric energy.
Description
Technical field
The utility model belongs to hydroelectric installation, and particularly the hydroelectric installation of utilized head kinetic energy generating is made the field.
Background technique
Existing impulse turbine as Pelton wheel, is that the dependence high-velocity flow is that head kinetic energy impacts blade, promotes rotary wheel of water turbine rotation work done, drives the hydraulic turbine generator rotation and produces electric energy.This hydraulic turbine outlet water velocity is still very big, can reach 4～12m/s, and its kinetic energy is also considerable, and it is discharged as tail water, and the loss of its mechanical energy is bigger, and the conversion ratio between mechanical energy and the electric energy is lower.
The model utility content
Task of the present utility model is to provide a kind of energy-saving type hydroelectric installation at the problems referred to above, is intended to improve the conversion ratio between head kinetic energy and the electric energy.This task is realized by following design, a kind of energy-saving type hydroelectric installation, comprise impulse turbine and corresponding supporting hydraulic turbine generator, tubular turbine and corresponding supporting hydraulic turbine generator, it is characterized in that, described tubular turbine is positioned at the lower position of impulse turbine water outlet, through sewer its water intake is communicated with the water outlet of impulse turbine; The main shaft of the web of this tubular turbine stretches out outside the casing, and connects with the main shaft of generator amature by a mechanical transmission mechanism.From above-mentioned design as seen, lower position at the impulse turbine water outlet is provided with tubular turbine, further to utilize the kinetic energy of impulse turbine water outlet tail water, the tubular turbine main shaft drives supporting with it hydraulic turbine generator through mechanical transmission machinery on the overhanging position of casing.Set velocity ratio, then can make this hydraulic turbine generator reach rated speed, make it the generating that runs well.Thereby for existing single impulse turbine generating, this is novel further to have utilized its tail water energy, and is converted into electric energy, has improved the conversion ratio between head kinetic energy and the electric energy.
Description of drawings
Accompanying drawing is this novel embodiment's a sectional view.
Embodiment
In the accompanying drawing, (Pelton wheel does not draw among the figure hydraulic turbine generator supporting with it, this generator directly connects with hydraulic turbine main shaft through coupling) belong to a kind of of impact type engine using hydrostatic thrust (relying on high-velocity flow is that head kinetic energy impacts blade and promotes rotary wheel of water turbine rotation work done), it is by forming with the bottom: housing 5, be installed in the rotating disk 3 on the hydraulic turbine main shaft 4, the along the circumferential direction uniform water bucket type blade 2 that is provided with on the rotating disk 3, more than 8 at nozzle, as 4, arrange at grade with runner, jet direction is a tangent direction, and housing 5 is provided with inlet tube 1, and its water outlet is through a sewer 6.The water intake of (can adopt metallic material or reinforced concrete make) and the tubular turbine that is arranged on this water outlet lower position (flow channels linearly or the axial flow hydraulic turbine of S type layout) is communicated with, be combined into a single unit system, whole casing is by forming with the bottom: housing S, sewer 6, housing 15; Casing is provided with inlet tube 1 and outer pipe 16.The solid of rotation 7a of this tubular turbine is provided with blade 7, the main shaft 10 of solid of rotation stretches out outside this casing, its sponson is provided with mechanical transmission mechanism, as belt gear (also can adopt gear transmission etc.), driving wheel 11 is fixed on main shaft 10 and stretches out on the position of casing, and follower 12 is fixed on (14 are generator unit stator) on the main shaft of generator amature 13.Be provided with guide vane 9 in the housing 15.Above-mentioned two water turbine, the high potential difference of impulse water turbine (containing Pelton wheel) and tubular turbine (be between the horizontal axis of water intake of the water outlet of last water turbine and back one water turbine height and position poor) can adopt 1.5～3m; The velocity ratio of above-mentioned driving wheel 11 and follower 12 is between 3: 1 to 10: 1, and basic demand is to make generator amature 13 reach its rated speed by mechanical transmission, between 100-300 rev/min.
During use, do not having under the natural high-velocity flow situation, can from the pond, draw water by a water pump, again high-velocity flow is sent into water intake 1, high-velocity flow impacts water bucket type blade 2 by nozzle 8, main shaft 4 is rotated, and make the hydraulic turbine generator (not shown) that is installed on the main shaft rotate generating, its tail water is through housing 5 water outlets, sewer 6, and the housing 15 of flowing through is through guide vane 9 guiding, the blade 7 of flowing through, make main shaft 10 rotate work done, after the driving mechanism transmission makes the sub-rotor of generating reach rated speed and normal power generation.Above-mentioned driving wheel 11, it can play the effect (also can take the independent mode that a flywheel is installed again on main shaft 10, with energy accumulation) of flywheel on the main shaft 10.The tail water that flows out from outer pipe 16 can return the system of pond and recycle.Also can adopt the setting of three water turbine tandem connections in the system of pond, corresponding three generators are taked the mode of externally output electric energy in parallel.
