Description
Technical field
The utility model relates to a kind of generator, especially relates to a kind of turbine-generator units post set Electric ring machine structure.
Background technology
At present, existing hydroelectric generator is mainly generated electricity by the drop of current, first wants ponding, by certain height, generate electricity with the hydraulic turbine of generator after forming hydraulic pressure, i.e. so-called drop hydroelectric generator, be mainly used in mountain region, hills, drop is larger, discharge is also larger.Chinese patent discloses a kind of hydro-generating Unit (publication number: CN101545444A), it comprises a fixed mount, generator is provided with at fixed mount, multiple current collector is provided with successively below fixed mount, the water wheels assembly that can rotate under natural flowing water drives is provided with at each current collector port of export, be provided with transmission mechanism at water wheels assembly and asking of generator, the water wheels assembly front end under fixed mount is provided with the adjustable adjusting device entering the discharge size of water wheels assembly; Current collector is the housing of a cone-shaped, and its arrival end is greater than the port of export, before each adjusting device is located at water wheels assembly respectively; Adjusting device is included in multiple adjustment sheets that water wheels assembly space before is arranged, and adjustment sheet is arranged on the rotating shaft, and be provided with pivoted arm on the rotating shaft, pivoted arm is regulated by pull bar, and pull bar is provided with the power piston that can drive pull bar work; Pull bar comprises the attached pull bar promoted mainly pull bar and be connected with pivoted arm be connected with power piston, is connected promoting mainly between pull bar and attached pull bar by triangle lever.But the collector ring of this generator is placed between end cap and bearing, thus in generator operation, coil damage ratio is comparatively serious, and remove contamination more difficult, operational efficiency is lower.
Utility model content
The utility model is to provide a kind of turbine-generator units post set Electric ring machine structure, the collector ring of its generator mainly solved existing for prior art is placed between end cap and bearing, thus in generator operation, coil damage ratio is more serious, remove contamination more difficult, the technical problem of the lower grade of operational efficiency.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Turbine-generator units post set Electric ring machine structure of the present utility model, comprise the generator be fixed in concrete foundation, described generator is connected with main shaft, main shaft is connected with flywheel, the rear end of main shaft is socketed with collector ring, the bottom of generator is connected with fan housing, and fan housing extend in concrete foundation, and is provided with axial flow blower in fan housing.Collector ring is placed on the rear end of main shaft and is connected with it by keyway, thus avoids the magnetic pole pollution coil that carbon dust can fly into collector ring.The width of concrete foundation in air channel will expand than ever, and its width can be consistent with the width of whole generator.When fan housing volume is larger, bottom fan housing, support can be had.Concrete foundation bottom should be communicated with air inlet.
As preferably, the axle body of described main shaft is provided with the conical surface, and flywheel is fixed on main shaft by the conical surface.Flywheel is connected with main shaft by tapering key, and make flywheel operationally have an axial force, the ability of drive electrical generators is stronger.
As preferably, described spindle nose is fixed with capping, and the outer surface of capping is provided with caulking groove, is embedded with adpting flange in caulking groove.Fixed by caulking groove and adpting flange at spindle nose, the dismounting of such adpting flange is comparatively simple, and the carbon brush replacing of collector ring brush holder is also extremely convenient.
As preferably, the inside of described adpting flange is provided with cavity, and in cavity, cross-under has overspeed protection device, and the connecting rod of overspeed protection device is stretched into after in cavity and is fixed together by latch and adpting flange.Overspeed protection device can issue a signal to digital control system when main shaft rotates too fast, thus the speed that ensures is limited in certain scope.
As preferably, the two ends of described generator are all connected with large end cap, small end cover.Designed by dual-end cover, dismounting more on the one hand, the internal structure of generator of can more fitting on the other hand.
As preferably, described main shaft is connected with bearing.Main shaft can be made more smooth and easy rotatably by bearing.
Therefore, collector ring is arranged on the rear end of main shaft by the utility model, carbon dust can be avoided to fly into the magnetic pole of collector ring, preventing pollution coil, and installing/dismounting is than greatly improving in the past and facilitating, and the carbon brush replacing of brush holder is also extremely convenient, simple and reasonable for structure.
