Abstract
The invention discloses a mounting and positioning rack for inner and outer rings on a downstream side of a water distributor of a bulb tubular hydro turbine generator unit. The positioning rack is provided with a large rack shaped like 'intersecting parallels' and a small rack shaped like 'intersecting parallels', wherein the large rack and the small rack are welded with steel. End parts of the large rack shaped like 'intersecting parallels' and the small rack shaped like 'intersecting parallels' are fixedly connected with end faces of the outer ring and the inner ring on the downstream side of the water distributor respectively. The large rack shaped like 'intersecting parallels' and the small rack shaped like 'intersecting parallels' are fixedly connected into a whole through a jack. Through fixed connection with the end faces of the inner ring and the outer ring on the downstream side of the water distribution, the positioning jack connects the inner ring and the outer ring of the water distributor into a whole, thereby increasing the structural strength of the whole water distributor, ensuring constant relative positions of the inner ring and the outer ring in a hoisting process, reducing mounting difficulty and improving mounting quality. In addition, the large and small racks shaped like 'intersecting parallels' increase the strength of the outer ring and the inner ring, ensure the circular degree of the outer ring and the inner ring of the water distributor, reduce deformation in the hoisting process and further improve mounting precision.
Description
Technical field
The present invention relates to a kind of super large type light bulb through-flow type hydro-turbo generator set water guide mechanism downstream inner and external rings installation locating rack, belong to the scaled bulb tubular hydraulic generator technical group field.
Background technique
From world's hydroelectric development trend as can be seen, the significance of low-head hydroelectric plant construction grows stronger day by day, the size of generator set is also developing to large-scale, super-huge direction, and China water power market also from high head to low-head development, thereby make that the scaled bulb tubular hydraulic generator group has been subjected to academia and industrial circle is paid close attention to widely.
The scaled bulb tubular hydraulic generator group mainly comprises the water turbine and the generator of a shared main shaft, and generator, bearing part are arranged in the light bulb head, and whole unit places runner according to tubular seat and supplemental support level; Tubular seat is made up of interior ring and outer shroud, and current pass through between the inner and outer rings of tubular seat; Water turbine is formed by imbedding mechanism, water distributor, rotation and auxiliary deployment mechanism, and the water distributor composition includes interior ring, outer shroud, is installed on the stator between the inner and outer rings.Installation for scaled bulb tubular hydraulic generator group water distributor part, the inventor designs a kind of water distributor of prepackage earlier, and the field erected method in back greatly reduces the field erected time, shortened the duration, and improved installation precision, reduced installation risk.But the water distributor lifting is put in place, need guarantee the structural strength of whole water distributor, especially the structural strength between the water distributor inner and outer rings.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of super large type light bulb through-flow type hydro-turbo generator set water guide mechanism downstream inner and external rings installation locating rack that can guarantee the water distributor structural strength is provided.
The technical solution adopted for the present invention to solve the technical problems is as follows: the super large type light bulb through-flow type hydro-turbo generator set water guide mechanism downstream inner and external rings installation locating rack, it is characterized in that having big " # " cabinet frame and little " # " cabinet frame that constitutes by the steel welding, fixedlying connected with the end face of water distributor downstream side outer shroud, interior ring respectively in the end of described large and small " # " cabinet frame, fixedlys connected by support between big " # " cabinet frame and little " # " cabinet frame to be integral.
Beneficial effect of the present invention is as follows: the mode of installing and locating frame of the present invention by fixedlying connected with the inner and outer rings end face in water distributor downstream side, the inner and outer rings of water distributor is fixed as one, strengthened the structural strength of whole water distributor, guaranteed that the inside and outside ring relative position remains unchanged in hoisting process, reduce installation difficulty, improved installation quality; And large and small " # " cabinet frame has been strengthened the intensity of outer shroud, interior ring, has guaranteed the circularity of outer gate barrel and interior ring, has reduced the deformation in the hoisting process, has further improved the precision of installing.
