Abstract
The utility model relates to a hydroelectric generator part, in particular to a sand-preventing pump plate mechanism of a hydroelectric generator top cover, and mainly solves the problems that a top cover of a generator in the prior art is not provided with a sand-preventing mechanism, and therefore during an operation process of a machine set, water containing sand in a volute enters main shaft sealing, a main shaft is damaged, and service life of the generator is short and the like. The mechanism comprises the top cover (1) and a bottom ring (2), and is characterized in that the main shaft (3) is connected with the top cover (1) in a penetrating mode, the main shaft is connected with a rotating wheel, two sides of the rotating wheel are provided with water inlets, the outer end of the rotating wheel is provided with a water outlet, and one end of the top cover (1) and one end of the bottom ring (2) are fixedly connected with the volute (4). A guide vane (5), on the volute, is connected with the top cover in a penetrating mode, the guide vane is connected with a connecting rod (7) through a guide vane arm (6), the connecting rod is connected with a control ring (8), and a water inlet of the top cover is provided with a sand-preventing pump plate (9).
Description
Technical field
The utility model relates to a kind of hydroelectric generator parts, especially relates to a kind of hydroelectric power machine cap sand prevention pump plate mechanism.
Background technique
At present, existing hydroelectric generator mainly is that the drop by current generates electricity, and at first wants ponding, by certain height, the water turbine with generator behind the formation hydraulic pressure generates electricity, i.e. so-called drop hydroelectric generator, be mainly used in mountain region, hills, drop is larger, water flow is also larger.Chinese patent discloses a kind of hydroelectric power unit (publication number: CN 101545444A), it comprises a fixing frame, be provided with generator at fixing frame, below fixing frame, be provided with successively a plurality of slip rings, be provided with the water wheels assembly that can under natural flowing water drives, rotate at each slip ring outlet end, be provided with driving mechanism asking of water wheels assembly and generator, the water wheels assembly front end under fixing frame is provided with the controlling device that can regulate the water flow size that enters the water wheels assembly; Slip ring is the housing of a cone-shaped, and its entry end is greater than outlet end, and each controlling device is located at respectively before the water wheels assembly; Controlling device is included in a plurality of adjustment sheets that water wheels assembly space before arranges, and adjustment sheet is arranged on the rotatingshaft, is provided with pivoted arm at rotatingshaft, and pivoted arm is regulated by pull bar, is provided with the power piston that can drive pull bar work at pull bar; Pull bar comprise be connected with power piston promote mainly pull bar and the attached pull bar that is connected with pivoted arm, connect by the triangle lever promoting mainly between pull bar and the attached pull bar.But the cover plate that this generator adopts is without sand prevention mechanism, and therefore in the process of unit operation, the silt part that contains in the water in the spiral case can enter main shaft seal, causes the wearing and tearing to main shaft, thereby so that reduces the working life of generator.
The model utility content
The utility model provides a kind of hydroelectric power machine cap sand prevention pump plate mechanism, it mainly is to solve the cover plate of the existing generator employing of prior art without sand prevention mechanism, therefore in the process of unit operation, the silt part that contains in the water in the spiral case can enter main shaft seal, cause the wearing and tearing to main shaft, thus so that the technical problem of reduction in the working life of generator etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Hydroelectric power machine cap sand prevention pump plate of the present utility model mechanism, comprise top cover and base ring, cross-under has main shaft on the described top cover, and main shaft is connected with runner, and the both sides of runner are water intake, the outer end of runner is water outlet, one end of top cover and base ring is fixed with spiral case, and cross-under has stator on the top cover at spiral case place, and stator connects connecting rod by guide vane lever, connecting rod connects control ring, and the water inlet of top cover is provided with anti-shell pump plate.After a side of cover plate was installed anti-shell pump plate, the silts of the overwhelming majority were stopped by sandboard in the water, can not enter main shaft seal, caused the wearing and tearing of main shaft also relative minimizing.Current can enter from the both sides of runner, after rotating via runner, discharge from the outer end of runner.Stator can play the effect of switch, and control ring can be controlled the aperture of stator.
As preferably, described runner includes the crown fixing with main shaft, and crown connects lower ring by blade.Blade can be set to multi-disc.
As preferably, described anti-shell pump plate is more than 2.Number, the shape of anti-shell pump plate is sediment charge what, the size decision by water.
Therefore, the utility model can make in the water silt of the overwhelming majority be stopped by sandboard after the cover plate place has increased anti-shell pump plate, can not enter main shaft seal, causes the wearing and tearing of main shaft also relative minimizing, and the working life of generator is longer, and is simple and reasonable for structure.
