Background technique
Axle extend through flow type hydraulic turbine is a kind of of tubular-turbine generator group, has structure, arranges that succinctly the factory building civilwork engineering quantity is less, and unit equipment transportation and erection weight are lighter, and construction and equipment are easy for installation.But select this type reduction of erection time, realize in advance generating (comparing with the axial flow unit).The relevant statistics in water power plant shows both at home and abroad, adopts the through-flow unit than same capability axial flow unit, but cost saving 10%-25% increases annual electricity generating capacity 3%-5%, has obvious economic advantages.Shaft extension through-flow unit divides again front shaft extension and two kinds of forms of rear shaft extension.
Have two kinds of device forms at the shaft extension through-flow unit that moves at present, be respectively two kinds of direct connection and speedups, runner diameter for the less power station of unit power output, such as 100KW, be not to be fit to very much just, and its installation period is longer generally more than 1 meter.
The model utility content
It is high that technical problem to be solved in the utility model provides a kind of comprehensive utilization ratio, the integrated shaft extension axial-flow hydrogenerator group that generated energy is large.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of integrated shaft extension axial-flow hydrogenerator group, comprise base and all be positioned at water turbine, speed regulator, thrust box and generator on the base, described water turbine has rotatable parts, described speed regulator is positioned on the described rotatable parts, and described thrust box is between described water turbine and generator.
Further, be provided with coupling in the described thrust box.
Further, described water turbine has main shaft, and described generator is connected with the main shaft of water turbine by coupling.
Further, described generator is provided with rotating shaft, and described thrust box and alternator shaft interconnect.
Further, described water turbine is axle extend through flow type hydraulic turbine.
Further, described water turbine comprises water feed apparatus, water distributor, runner envelope and the drainage means that connects successively.
Working principle: the water that will have certain drop flows through water turbine, and the runner of water turbine rotates, and the potential energy converting and energy of water is mechanical energy, and the water turbine of rotation drives generator operation by coupling, and mechanical energy is converted to electric energy the most at last.
Beneficial effect: than prior art, the utility model changes the setting type of present existing shaft extension through-flow unit, critical piece in the unit is installed on the base, such structural configuration is not only simple and clear, and can also improve the comprehensive utilization ratio of unit, increase the generated energy of unit, complete equipment is assembled in factory and is debugged, directly shipping to power station installation gets final product after the assay was approved, greatly reduced the building site installation workload, also shortened construction period, in addition, when unit need to be safeguarded, shut the water inlet and outlet valve, opening runner envelope can overhaul, if the scene does not possess the maintenance condition, can unclamp with the bolt of inlet with the bolt at ell place, water turbine integral body hung original position can be transported to overhaul shop or manufactory carries out large repairs, easy to maintenance, unit need to be reserved form that 3-4 place lower margin props up pier foundation with original shaft extension through-flow unit and only change fixedly that the water turbine base is pourable the second stage of concrete into, saved investment, be particularly suitable for less (unit power output 300KW the is following) runner diameter of unit power output and select less than the power station of 700mm.
Description of drawings
Fig. 1 is the plan view of the utility model integrated shaft extension axial-flow hydrogenerator group.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, integrated shaft extension axial-flow hydrogenerator group of the present utility model, comprise base 5 and all be positioned at water turbine 1 on the base 5, speed regulator 2, thrust box 3 and generator 4, water turbine 1 has rotatable parts, speed regulator 2 is positioned on the rotatable parts of water turbine 1, thrust box 3 is between water turbine 1 and generator 4, thrust box 3 is section's external members of an assembling, there is bearing the inside, the axial hydraulic thrust that thrust box 3 produces when being used for bearing unit operation, be provided with coupling in the thrust-bearing 3, generator 4 links to each other by the main shaft of coupling with water turbine 1, thrust box 3 links to each other with the rotating shaft of generator 4, and water turbine 1 is axle extend through flow type hydraulic turbine, and this water turbine 1 comprises the water feed apparatus that connects successively, water distributor, runner envelope and drainage means.
Working principle: the water that will have certain drop flows through water turbine 1, and the runner of water turbine 1 rotates, and the potential energy converting and energy of water is mechanical energy, and the water turbine 1 of rotation drives generator 4 runnings by coupling, and mechanical energy is converted to electric energy the most at last.
The integrated shaft extension axial-flow hydrogenerator group that provides in a certain power station trial edition model utility:
Turbine parameter is made as:
Impeller diameter: 0.6m
Sucking-off is high :-1.5m
Rated head: 12m
Rated flow: 1.5m
3/ s
Rated speed: 750rpm
Runaway speed: 1350rpm
