(the binding structure of inlet side pipe 21 and outlet side pipe 22)
The structure of explanation is kept by the tubular binding parts 6 that are configured in stator 7 outsides with being described below above.At first; On the whole circumference of the outlet side end of inlet side pipe 21, be formed with to the side-prominent ring-type eaves portion 219 of periphery; On the other hand; The inlet side end that links parts 6 at tubular is formed with engaging teat 61, and these engaging teat 61 inside all lateral bendings are bent, at the whole inlet side end face that hooks ring-type eaves portion 219 on circumferentially.In addition; Be formed with to the side-prominent ring-type eaves portion 229 of periphery in the inlet side end of outlet side pipe 22; On the other hand; The outlet side end that links parts 6 at tubular is formed with the ring-type bending part 62 that links usefulness, and these bending part 62 inside all side bendings are with the outlet side end face riveted joint of ring-type eaves portion 229.
At this, tubular links inlet side end (engaging teat 61) inside all lateral bending song when being used for water power generation device 1 of parts 6.On the contrary; The bending part 52 of tubular connected element 6 is through linking the outlet side end that parts 6 back bending tubulars link parts 6 from the chimeric tubular of inlet side and form straight before this extension rotor 8, stator 7 and tubular sealed member 5 being clamped under the state between inlet side pipe 21 and the outlet side pipe 22 when water power generation device 1.
Therefore; When water power generation device 1; At first; After rotor 8, stator 7 and tubular sealed member 5 being clamped between inlet side pipe 21 and the outlet side pipe 22, link parts 6 from the chimeric tubular of inlet side, the ring-type eaves portion 219 that the engaging teat 61 that makes tubular link parts 6 hooks inlet side pipe 21, afterwards; Form the bending part 62 of ring-type as if tubular is linked the inside all side bendings in outlet side end of parts 6, then inlet side pipe 21 is being clamped in rotor 8, stator 7 and tubular sealed member 5 under the state therebetween by 6 bindings of tubular binding parts with outlet side pipe 22.
In this example, tubular links parts 6 and is formed by magnetic, and tubular links parts 6 and also plays the effect with the iron core of the outer circumferential side covering of coil 72.
(action)
In the hydroelectric installation 1 that constitutes like this, water gets into from the inlet side opening of inlet side pipe 21, and the quiet wing 31 places in being formed at the inlet side pipe become eddy current and impact the moving wing 831, and the moving wing 831 receives this hydraulic pressure.At this, form as one with rotor 8 owing to move the wing 831, so rotor 8 is around pivot 4 rotations.In addition, owing on rotor 8, be fixed with rotor magnet 81, so rotor magnet 81 rotations.Consequently, rotor magnet 81 passes its magnetic force the stator iron core 73 in the tubular sealed member 5 guiding outsides.Stator iron core 73 links parts 6 with tubular and constitutes magnetic circuit, in the space that is separated to form by stator iron core 73 and tubular binding parts 6, is wound with coil 72.Therefore, can in coil 72, produce electromotive force.
At this moment,, therefore may produce wearing and tearing, but owing between the receiving portion 222 of rotor 8 and outlet side pipe 22, dispose anti abrasive thrust washer 45, so can not produce problem such as wearing and tearing because rotor 8 is pushed towards outlet side by current.
On the other hand, the water behind the moving wing 831 of impact is discharged from the outlet side opening in the inboard of flowing through cylindric rotor housing 84 and outlet side pipe 22 backs.In addition; The part of water flows through between cylindric rotor housing 84 and the tubular sealed member 5 and arrives outlet side pipe 22; But, therefore can not leak at inlet side and outlet side because tubular sealed member 5 keeps liquid sealing by O shape circle 56,57 respectively with respect to outlet side pipe 22 and inlet side pipe 21.
(the main effect of this example)
As stated, in the hydroelectric installation 1 of this example, cylindric rotor housing 84 has the big footpath of rotor-side tube portion 843, and the big footpath of this rotor-side tube portion 843 is from the outside of inlet side enlarged-diameter to the moving wing 831 external end edges of the holding position of rotor magnet 81.Therefore, make the wing 831 postrotational water can be drawn towards the inboard of cylindric rotor housing 84, and can be to the flows outside of rotor magnet 81 residing cylindric rotor housings 84.Therefore, can the water yield that contact with rotor magnet 81 be suppressed on a small quantity, even it is therefore in water, contain the occasion of iron powder, also less attached to the iron powder amount on the rotor magnet 81.Thus, therefore the malrotation of the rotor 8 that can not take place for a long time to cause because of the iron powder that is adsorbed on the rotor magnet 81 can improve the reliability of hydroelectric installation 1.
In addition; Owing on the outer circumferential face of the outside cylindrical portion 832 that the external end edge with the moving wing 831 links, be formed with spiral chute 833; When rotor 8 rotations; The hydrodynamic pressure that this spiral chute 833 forms towards inlet side, therefore can prevent sealing via the outside of the moving wing 831 and the driven wing 831 in gap of the quiet wing 31 around the outside to cylindric rotor housing 84, can be suppressed to the water yield that leaks into cylindric rotor housing 84 outsides less.In addition, owing to be to make the outlet side end of outside cylindrical portion 832 and the chimeric structure in inlet side end of the big footpath of rotor-side tube portion 843, therefore can prevent that the outside of the interior side direction rotor 8 of driven wing component parts 83 from leaking.In addition; Owing on tubular sealed member 5, be formed with the big footpath of sealed member side tube portion 53; Between the outer circumferential face of sealing component side big footpath tube portion 53 and the big footpath of rotor-side tube portion 843, constitute ring-type micro-gap 11, the water yield that therefore can leak into cylindric rotor housing 84 outsides with getting between tubular sealed member 5 and the cylindric rotor housing 84 is suppressed to less.In addition; Because the inlet side end face of outlet side pipe 22 and the outlet side end of cylindric rotor housing 84 form crooked annular gap 12; This annular gap 12 is being brought into play the mazy type sealing effect, and the water that therefore can prevent to flow through the interior rear flank of cylindric rotor housing 84 flows to the outside of cylindric rotor housing 84 is counter.Therefore, owing to can the water yield that contact with rotor magnet 81 be suppressed on a small quantity, even therefore in water, contain the occasion of iron powder, also can be with being suppressed to less attached to the iron powder amount on the rotor magnet 81.
In addition; Owing to set the gap size (gap size of small annular gap 11) between the big footpath of rotor-side tube portion 843 and the big footpath of the sealed member side tube portion 53 in the gap size between rotor 8 and the tubular sealed member 5 minimum dimension; Even therefore get into the occasion between rotor 8 and the tubular sealed member 5 at iron powder and other slag inclusion; This slag inclusion can not stop up between rotor 8 and tubular sealed member 5 yet, so rotor 8 can rotate with stable status for a long time.
In this example; Between stator 7 and rotor magnet 81, dispose the tubular sealed member 5 that constitutes liquid sealing with inlet side pipe 21 and outlet side pipe 22 respectively; And dispose tubular in the outside of stator 7 and link parts 6, this tubular links parts 6 and under the state that stator 7 is clamped between inlet side pipe 21 and the outlet side pipe 22, inlet side pipe 21 and outlet side pipe 22 is linked.Therefore; When assembling the hydroelectric installation 1 of this example; If link inlet side pipe 21 and outlet side pipe 22 rotor 8, tubular sealed member 5 and stator 7 being configured under the state between inlet side pipe 21 and the outlet side pipe 22 with tubular binding parts 6; Then inlet side pipe 21 is stipulated with the position of outlet side pipe 22 on axial direction, therefore can open the moving wing 831 of specified gap ground configuration and the quiet wing 31 by sky.In addition, owing to the radial position of inlet side pipe 21 and outlet side pipe 22 is stipulated by tubular sealed member 5, so pivot 4 (rotary middle spindle of rotor 8) can not tilt.Therefore, can stably obtain higher generating efficiency.In addition, the inboard of tubular sealed member 5 watertight ground maintenance stator 7 capable of using.And, owing to there is not a screw thread fixed position, maybe can the screw thread fixed position be constrained to minimum etc., can simplified construction, therefore can reduce the cost of parts and the assembly cost of hydroelectric installation 1.
In addition; In this example; For the inlet side end that makes tubular link parts 6 engages with the outlet side end of inlet side pipe 21; Be formed with to the side-prominent ring-type eaves portion 219 of periphery in the end of inlet side pipe 21, be formed with inside week in the inlet side end that tubular links parts 6 side-prominent and hook the engaging teat 61 of ring-type eaves portion, therefore can easily assemble.
In addition; In this example; For the inlet side end of the outlet side end that tubular linked parts 6 and outlet side pipe 22 links; Adopted the inside all side bendings in outlet side end that make tubular binding parts 6 and made bending part 62 be riveted on the structure in the ring-type eaves portion 229,, then can easily assemble if adopt this riveted joint structure.
