(structure of tubular sealed member 5)
See Fig. 1 again, dispose the tubular sealed member 5 that metal forms in the annular gap between stator 7 and rotor magnet 81.Tubular sealed member 5 comprises: the path cylindrical part 51 between stator 7 and rotor magnet 81, the lip part 52 that enlarges towards radial outside in the inlet side end of this path cylindrical part 51 and from the outer periphery of lip part 52 towards the big footpath of sealed member side tube portion 53 that the inlet side equal diameter is extended.It is fixing that stator 7 utilizes the stepped part that is made of path cylindrical part 51 and lip part 52 to position, and it is fixing that the inner peripheral surface of stator 7 utilizes the outer circumferential face of path cylindrical part 51 to position.Therefore, can easily and carry out the assembling of stator 7 reliably.
In tubular sealed member 5, O shape circle 56 is installed in the outlet side end of path cylindrical part 51, utilize this O shape circle 56 liquid sealings of guaranteeing between tubular sealed member 5 and the outlet side pipe 22.In addition, in tubular sealed member 5, O shape circle 57 is installed in the outlet side end of the big footpath of sealed member side tube portion 53, utilizes this O shape circle 57 liquid sealings of guaranteeing between tubular sealed member 5 and the inlet side pipe 21.
At this, on the whole circumference of the outlet side end face of inlet side pipe 21, be formed with first groove 215, in this first groove 215, be inserted with the inlet side end of tubular sealed member 5, the depths butt of the inlet side end of tubular sealed member 5 and first groove 215.In addition, on the whole circumference of the inlet side end face of outlet side pipe 22, be formed with second groove 225, in this second groove 225, be inserted with the outlet side end of tubular sealed member 5, the depths butt of the outlet side end of tubular sealed member 5 and second groove 225.Therefore, the inlet side end of tubular sealed member 5 with respect to inlet side pipe 21 under the confined state of radial position with inlet side pipe 21 butt on axial direction, the outlet side end of tubular sealed member 5 with respect to outlet side pipe 22 under the confined state of radial position with outlet side pipe 22 butt on axial direction.
Under this state, the big footpath of sealed member side tube portion 53 is positioned at than the big footpath of rotor-side tube portion 843 more by on the position of radial outside, formation ring-type micro-gap 11 between the outer circumferential face of the inner peripheral surface of the big footpath of sealed member side tube portion 53 and the big footpath of rotor-side tube portion 843.In this example, the gap size of the ring-type micro-gap 11 that will be formed by the big footpath of rotor-side tube portion 843 and the big footpath of sealed member side tube portion 53 is set the minimum dimension in the gap size between rotor 8 and the tubular sealed member 5 for.
In this example, the part that the inlet side end face of outlet side pipe 22 utilizes the stepped part of ring-type to make and is positioned at outer circumferential side is outstanding to inlet side more.On the other hand, the outlet side end of cylindric rotor housing 84 is arranged in the most inboard recess 228 of the inlet side end face of outlet side pipe 22, and the outlet side end face of cylindric rotor housing 84 is relative under the state close along axial direction with the bottom of recess 228.Under this state, with respect to the outer circumferential side of the outer circumferential face of the outlet side end of cylindric rotor housing 84, interior all sides of the recess 228 of outlet side pipe 22 under radially close state relatively.Like this, the inlet side end face of outlet side pipe 22 is relative down with the state that the outlet side end of rotor 8 is formed with crooked annular gap 12 betwixt.
(the binding structure of inlet side pipe 21 and outlet side pipe 22)
Described above being constructed as follows describedly kept by the tubular binding parts 6 that are configured in stator 7 outsides.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, these engaging teat 61 inside all lateral bending songs are 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, 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 assembling hydroelectric installation 1 of parts 6.On the contrary, the bending part 52 of tubular connected element 6 is to form straight before this extension by the outlet side end from the chimeric tubular binding of inlet side parts 6 back bending tubulars binding parts 6 under the state that rotor 8, stator 7 and tubular sealed member 5 is clamped between inlet side pipe 21 and the outlet side pipe 22 when assembling hydroelectric installation 1.
Therefore, when assembling hydroelectric installation 1, at first, with rotor 8, after being clamped between inlet side pipe 21 and the outlet side pipe 22, stator 7 and tubular sealed member 5 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 if tubular linked the inside all side bendings in outlet side end of parts 6, then inlet side pipe 21 and outlet side pipe 22 are with rotor 8, stator 7 and tubular sealed member 5 are clamped in and are linked parts 6 by tubular under therebetween the state and link.
In this example, tubular links parts 6 and is formed by magnetic, and tubular links parts 6 and also plays 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 enters 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 is subjected to 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, is wound with coil 72 in the space that is separated to form by stator iron core 73 and tubular binding parts 6.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 is held in 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 mentioned above, in the hydroelectric installation 1 of 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, link inlet side pipe 21 and outlet side pipe 22 if under the state that rotor 8, tubular sealed member 5 and stator 7 is configured between inlet side pipe 21 and the outlet side pipe 22, link parts 6 with tubular, then inlet side pipe 21 and the position of outlet side pipe 22 on axial direction are prescribed, and 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, can utilize tubular sealed member 5 watertight feuds to keep the inboard of stator 7.And, owing to there is not the screw thread fixed position, maybe the screw thread fixed position can 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 and made tubular link the inside all side bendings in outlet side end of parts 6 and make bending part be riveted on structure in the ring-type eaves portion 229, if adopt this riveted joint structure, then can easily assemble.
In addition, in this example, on the outlet side end face of inlet side pipe 21, be formed with first groove 215, in this first groove 215, be inserted with the inlet side end of tubular sealed member 5, and the depths butt of this inlet side end and first groove 215, on the inlet side end face of outlet side pipe 22, be formed with second groove 225, in this second groove 225, be inserted with the outlet side end of tubular sealed member 5, and the depths butt of this outlet side end and second groove 225.Therefore, can be easily and stipulate reliably inlet side pipe 21 and outlet side pipe 22 radially with thrust direction on the position.
In addition, in this example, when rotor 8 rotation, rotor 8 rotates under by the state of outlet side pipe 22 restrictions in the position of outlet side direction.At this moment, because the moving wing 831 is subjected to hydraulic pressure, therefore on outlet side pipe 22, be applied with the power of the direction of leaving from inlet side pipe 21, but because outlet side pipe 22 utilizes tubular to link parts 6 links with inlet side pipe 21, even therefore be subjected to the power of this direction, also can prevent the generation of becoming flexible.
In addition, in 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 the extremely moving wing 831 external end edges of inlet side enlarged-diameter 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, the water yield that contacts with rotor magnet 81 can 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, the malrotation of the rotor 8 that causes because of the iron powder that is adsorbed on the rotor magnet 81 can taking place for a long time, therefore 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, therefore can will enter between tubular sealed member 5 and the cylindric rotor housing 84 and the water yield that leaks into cylindric rotor housing 84 outsides 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 the water yield that contacts with rotor magnet 81 can be suppressed on a small quantity,, also can will be suppressed to less attached to the iron powder amount on the rotor magnet 81 even therefore in water, contain the occasion of iron powder.
In addition, owing to the minimum dimension in the gap size of the gap size between the big footpath of rotor-side tube portion 843 and the big footpath of the sealed member side tube portion 53 being set between rotor 8 and the tubular sealed member 5, therefore even enter 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 long-term and stably.

In above-mentioned example, link parts 6 and outlet side pipe 22 in order to link tubular, the whole circumference that makes tubular link the outlet side end of parts 6 forms bending part 62 towards interior all lateral bending songs, but also can adopt following structure: as Fig. 3 (a), shown in Fig. 3 (b), form a plurality of groove 229a in the outer periphery of the ring-type eaves portion 229 of outlet side pipe 22 along circumferential separation, on the other hand, as Fig. 3 (c), shown in Fig. 3 (d), link a plurality of projection 62as of the outlet side end formation of parts 6 at tubular along circumferential separation, after in projection 62a insertion groove 229a, make projection 62a bending to the inside and form bending part, link with outlet side pipe 22 thereby tubular is linked parts 6.If such formation, the root (root of projection 62a) that then becomes bending part is entrenched in the interior state of groove 229a, therefore can upwards position tubular binding parts 6 and outlet side pipe 22 in week.In example shown in Figure 3, groove 229a and projection 62a are one group with two, form at interval with equal angles by twos, but also a plurality of groove 229a and projection 62a can be formed at interval with equal angles respectively.
[tubular links the variation 2 of the binding structure of parts 6 and outlet side pipe 22]
In addition, also can adopt following structure: shown in Fig. 4 (a), Fig. 4 (b), in the ring-type eaves portion 229 of outlet side pipe 22, form a plurality of hole 229b along circumferential separation, on the other hand, shown in Fig. 4 (c), Fig. 4 (d), form a plurality of projection 62a along circumferential separation in the outlet side end that tubular links parts 6, in projection 62a patchhole 229b after, make projection 62a bending to the inside and form bending part, link with outlet side pipe 22 thereby tubular is linked parts 6.If such formation, the root (root of projection 62a) that then becomes bending part is entrenched in the interior state of hole 229b, therefore can upwards position tubular binding parts 6 and outlet side pipe 22 in week.In example shown in Figure 4, hole 229b and projection 62a are one group with two, form at interval with equal angles by twos, but also a plurality of hole 229b and projection 62a can be formed at interval with equal angles respectively.
[tubular links the variation 3 of the binding structure of parts 6 and outlet side pipe 22]
In addition, also can adopt following structure: shown in Fig. 5 (a), Fig. 5 (b), in the ring-type eaves portion 229 of outlet side pipe 22, on equal angles position at interval, form a plurality of hole 229c along circumferential separation with form along extending circumferentially, on the other hand, shown in Fig. 5 (c), Fig. 5 (d), link a plurality of projection 62as of the outlet side end formation of parts 6 at tubular along circumferential separation, after inserting two projection 62a in the same hole 229c, make projection 62a bending to the inside and form bending part, link with outlet side pipe 22 thereby tubular is linked parts 6.If such formation, the root (root of projection 62a) that then becomes bending part is entrenched in the interior state of hole 229c, therefore can upwards position tubular binding parts 6 and outlet side pipe 22 in week.
[tubular links the variation 4 of the binding structure of parts 6 and outlet side pipe 22]
In addition, also can adopt following structure: shown in Fig. 6 (a), Fig. 6 (b), go up at the outer circumferential face (the ring-type eaves 229d of portion outer circumferential face) of the inlet side end of outlet side pipe 22 and to form the external screw thread 229e that links usefulness, on the other hand, link at tubular on the inner peripheral surface of outlet side end of parts 6 and form female thread 62e, external screw thread 229e and female thread 62e are screwed, link with outlet side pipe 22 thereby tubular is linked parts 6.If constitute like this, then can prevent from reliably therefore can prevent the loosening of inlet side pipe 21, tubular sealed member 5 and outlet side pipe 22 in the gap that produces between inlet side pipe 21, tubular sealed member 5 and the outlet side pipe 22 on the axial direction.In addition, decomposition is also easy.
[other example]
In above-mentioned example, owing to adopted the structure that under the state that rotor 8, stator 7 and tubular sealed member 5 is clamped between inlet side pipe 21 and the outlet side pipe 22, links parts 6 from the chimeric tubular of inlet side, therefore the structure that adopts the outlet side end that after chimeric tubular links parts 6, tubular linked parts 6 and outlet side pipe 22 to link, but also can adopt under the state that rotor 8, stator 7 and tubular sealed member 5 is clamped between inlet side pipe 21 and the outlet side pipe 22 structure from the chimeric tubular binding of outlet side parts 6.At this moment, after chimeric tubular links parts 6, tubular is linked the inlet side end and 21 bindings of inlet side pipe of parts 6.
In addition, in above-mentioned example and variation, when using riveted joint in the binding that links parts 6 at pipe and tubular, make tubular link the end bending to the inside of parts 6, but in the occasion of projection, this wrap direction also can be circumferentially or the outside.
In addition, in above-mentioned example and variation, in the binding of pipe and tubular binding parts 6, used riveted joint, screw thread to screw, but also can adopt for example deposited other linking method that waits.
In addition, in above-mentioned example, the rotary middle spindle of rotor 8 is that two ends are fixed on the stationary axle (pivot 4) on inlet side pipe 21 and the outlet side pipe 22, but the rotary middle spindle of rotor 8 also can be that two ends are rotatably by the rotating shaft of inlet side pipe 21 and 22 supports of outlet side pipe.
In addition, in above-mentioned example, constitute the little structure of inlet side opening of the outlet side aperture efficiency inlet side pipe 21 of outlet side pipe 22, but the structure that the size that for example also can adopt the outlet side opening of outlet side pipe 22 equates with the size of the inlet side opening of inlet side pipe 21, perhaps as shown in Figure 7, the outside dimension D2 of the outlet side part of outlet side pipe 22 is equated with the internal diameter size D1 of the inlet side part of inlet side pipe 21, make the outlet side part of outlet side pipe 22 chimeric, thereby a plurality of hydroelectric installations 1 are connected in series with the inlet side pipe 21 of other hydroelectric installation 1.If constitute like this, the then available less water yield improves generating efficiency.In addition, can easily hydroelectric installation 1 be inserted in the way of water pipe etc. on the position.
In addition, in above-mentioned example, link with cylindrical bearing 82 in order to move wing component parts 83, the end of cylindrical bearing 82 is being riveted after the outstanding form of inlet side is inserted in the hole with driven wing component parts 83, but for example also can adopt following structure: the hole that in moving wing component parts 83, is formed centrally cross shape, on the other hand, cross shape is also made in the end of cylindrical bearing 82, thereby the end of the cross shape of cylindrical bearing 82 is pressed in the hole of cross shape of moving wing component parts 83.If such formation then because moving wing component parts 83 is subjected to the hydraulic pressure towards outlet side, even therefore loose in the telescoping part generation, moved wing component parts 83 and also can not come off.
In addition, also have the situation that kinetic energy-electric energy conversion device is constituted pump-unit, but basic structure, action effect and the hydroelectric installation 1 of this moment are roughly the same, have therefore omitted explanation.
