Abstract
The utility model relates to a water turbine volute structure for avoiding rigid deformation caused by water flow. The water turbine volute structure is used for avoiding rigid deformation produced under the effect of water flow impact. According to the water turbine volute structure for avoiding the rigid deformation caused by the water flow, a water input connection pipe section, a volute joint and a nose end are sequentially connected. The water turbine volute structure is characterized in that a rigid ring plate is welded outside the water input connection pipe, the rigid ring plate is provided with reinforcing ribs, one end of each reinforcing rib is connected to the rigid ring plate, and the other end of each reinforcing rib is connected with the outer wall of the water input connection pipe. The rigid ring plate and the reinforcing ribs are embedded into concrete and are connected with the ground to form a whole. Compared with an original volute structure, only one rigid ring plate and the multiple reinforcing ribs are added to the water input connection pipe section, and the concrete is poured. The water turbine volute structure is very simple, water flow impact resistant performance of the water input connection pipe section is improved, and sequentially structural deformation of the volute joint and the noise end is effectively avoided.
Description
Technical field
The utility model relates to the volute structure of water turbine that prevents current generation rigid deformation, is applied to the rigid deformation that prevents that spiral case from producing under water impact effect.
Background technique
Spiral case is the abbreviation of scroll casing type flume, and its profile is the spitting image of hodmadod, therefore be conventionally called for short spiral case.For guaranteeing evenly to supply water to water distributor, so the section of spiral case reduces gradually, it can form necessary circular rector before water distributor simultaneously, make current along whole even circumferential flow into water distributor, to alleviate the working strength of water distributor.Spiral case is the most general a kind of flume of application in reaction turbine, yet for existing welding spiral case, particularly larger spiral case, having a maximum problem is exactly to produce rigid deformation under the effect of current.
The worm frame generally adopting is now to connect pipeline section into water, the formations such as snail joint and nose, by they assembled being welded each other, because spiral case is larger, rigidity is poor, therefore when unit start operation, under the percussion of current, the stressed spiral case body that is directly passed to, thereby cause the rigid deformation of spiral case, the power station of high head particularly, because its water pressure is larger, cause its distortion meeting larger, serious words, can cause spiral case displacement, pass to the most important stressed part seat ring of the water turbine being welded as a whole mutually with it simultaneously, can the safe and stable operation in power station be caused and be had a strong impact on.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, provides a kind of and prevents that spiral case from producing rigid deformation and preventing that current from producing the volute structure of water turbine of rigid deformation under flow action.
The purpose of this utility model can reach by following technical proposals: prevent that current from producing the volute structure of water turbine of rigid deformation, water inlet connects pipeline section, snail joint and nose and is sequentially connected; It is characterized in that connecting rigidity Circular Plate of pipeline section outside weld into water; Rigidity annulus strip stiffening rib, stiffening rib one end is connected in rigidity Circular Plate, and the other end connects pipeline section outer wall with water inlet and is connected; In rigidity Circular Plate and stiffening rib Transducers Embedded in Concrete, with connecting as one greatly.
The utlity model has following advantage: compare with original worm frame, only just in water inlet, connect pipeline section and increase a rigidity Circular Plate and several stiffening ribs, and the concrete of having cast, its structure is very simple, improve the performance of water inlet connection pipeline section anti-current-rush, effectively avoided the malformation of follow-up snail joint, nose.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
In figure, 1 is snail joint, the 3rd, and nose, the 5th, enter water and connect pipeline section, the 7th, stiffening rib, the 9th, rigidity Circular Plate, the 11st, concrete.
Embodiment
The utility model is further described below in conjunction with accompanying drawing.Prevent that current from producing the volute structure of water turbine of rigid deformation, water inlet connects pipeline section (5), snail joint (1) and nose (3) and is sequentially connected; It is characterized in that connecting pipeline section (5) rigidity Circular Plate of outside weld (9) into water; Rigidity Circular Plate (9) band stiffening rib (7), it is upper that stiffening rib (7) one end is connected to rigidity Circular Plate (9), and the other end connects pipeline section (5) outer wall with water inlet and is connected; In rigidity Circular Plate (9) and stiffening rib (7) Transducers Embedded in Concrete (11), with connecting as one greatly.
Because water inlet connects pipeline section, increased a rigidity Circular Plate, the impact force that water flows into spiral case generation is absorbed by rigidity Circular Plate and peripheral concrete and the earth (large mass objects) thereof, has avoided to greatest extent the stress deformation of spiral case body.
