Along with the development in epoch, people find the Tough questions that the energy is petered out day by day, and increasing people starts to pay attention to clean energy resource, as hydroelectric power.Axial flow hydraulic turbine is undoubtedly wherein important one.Described axial flow hydraulic turbine comprises main shaft, water distributor and runner.Refer to shown in Fig. 1, described runner comprises runner body and draft cone.The draft cone of prior art is arranged on the lower end of described runner body by pressing plate and fastening piece.The madial wall of the lower end of runner is provided with radial limited ring.Described pressing plate is arranged in described runner body and this pressing plate is spacing on the upside of described radial limited ring.The middle part of described pressing plate is provided with tapped hole; The lower end of described draft cone is also provided with tapped hole; Double threaded screw is provided with between described pressing plate and the lower end of draft cone, the upper end of double threaded screw is put in the upside of described pressing plate through pressing plate tapped hole dew and with nut check, and the lower end of double threaded screw to be put outside described draft cone through the tapped hole dew of draft cone lower end and used nut check.There is following defect in the runner of the axial flow hydraulic turbine of this kind of prior art: installs due to draft cone and installed by pressing plate and fastening piece, installation is, need first screw rod and fixed plate to be assembled, put into the inner chamber of runner, and then draft cone is installed, screwing nut in the lower end of bolt again carries out fastening, installs and bothers very much.
Model utility content
The technical problems to be solved in the utility model is, provides a kind of runner of axial flow hydraulic turbine, and draft cone can be installed on runner body by the runner of this kind of axial flow hydraulic turbine easily.
Technical solution of the present utility model is, provides a kind of runner with the axial flow hydraulic turbine of following structure, comprises runner body and draft cone; Described draft cone is arranged on the lower end of described runner body; The installation bulge loop that the aperture that the lower end of described runner body is provided with the upper end-hole of external diameter and draft cone matches; The upper end-hole of described draft cone is linked in the outer and draft cone upper end-hole of described installation bulge loop and installs between bulge loop and is mutually permanently connected.
After adopting above structure, the runner of axial flow hydraulic turbine of the present utility model, compared with prior art, has the following advantages:
Because the runner of axial flow hydraulic turbine of the present utility model is when assembling runner body and draft cone, as long as the upper end-hole of draft cone is linked in outside the installation bulge loop of runner body, then the upper end-hole of draft cone is fixed with installation bulge loop and just can, install very simple, greatly reduce work difficulty.
Improve as one of the present utility model, the sidewall of the upper end-hole of described draft cone is provided with multiple through holes that can pass through for the helical thread portion of screw; On the sidewall of described installation bulge loop, the position corresponding with the through hole of the upper end-hole of described draft cone is provided with multiple tapped hole; Described multiple through hole aligns one by one with described multiple tapped holes; Often organize in through hole and tapped hole and be all provided with screw, the through through hole of helical thread portion of described screw screws in tapped hole.After adopting this kind of structure, between the upper end-hole of draft cone and installation bulge loop, means of fixation is comparatively simple, easy to assembly.
Improve as another kind of the present utility model, described each through hole is shoulder hole; The nut of the accommodating described screw of macropore energy of described shoulder hole; The aperture of described shoulder hole can pass through for the helical thread portion of described screw.After adopting this kind of structure, the nut of described screw can be contained in the macropore of described shoulder hole, makes runner outer side wall more smooth.
Also have a kind of improvement as of the present utility model, described through hole is provided with 8, and these 8 through holes are uniformly distributed along draft cone upper end-hole circumference; Accordingly, described tapped hole also has 8, and these 8 tapped holes are uniformly distributed along installing bulge loop circumference.After adopting this kind of structure, be connected more stable between described draft cone with installation bulge loop, this kind is designed to optimum implementation.
A kind of improvement is also had, in the macropore of described each shoulder hole and the outside being positioned at the nut of described screw is all filled with epoxy resin as of the present utility model.After adopting this kind of structure, filling epoxy resin can avoid screw pine, also can avoid falling in the macropore of shoulder hole ash, when needing knockout screw, as long as with fire bake epoxy resin make its melt just can, easy to operate.
