Fig. 1 shows the structure of a rotor wheel structure according to an embodiment of the present utility model. For convenience of explanation, the drawings show only structures related to the embodiments of the present utility model.

Referring to fig. 1 and 2, a rotor structure 100 according to a preferred embodiment of the present utility model includes a rotor body 110, a plurality of rotor blades 120, a plurality of operating mechanisms 130, and a front operating member 140.

Referring to fig. 3, the rotor body 110 has a hollow structure with a first opening end 111 and a second opening end 112 opposite to each other along the water flow direction. The sidewall of the rotor body 110 is provided with a plurality of mounting holes 113 at intervals in the circumferential direction. The water flow direction means a direction in which water flows in a hydraulic passage of the water turbine, and the circumferential direction of the runner body 110 means a circumferential direction rotating around an axis parallel to the water flow direction.

Referring to fig. 4, the plurality of rotor blades 120 are respectively in one-to-one correspondence with the plurality of mounting holes 113. The rotor blade 120 includes a mounting portion 122 and a blade 121 disposed at one end of the mounting portion 122. The mounting portions 122 rotatably penetrate through the corresponding mounting holes 113, and contact the paddles 121 with the outer wall of the rotor body 110. Thus, when the mounting portions 122 are inserted into the corresponding mounting holes 113, the edge portions of the paddles 121 near the mounting portions 122 are in contact with the outer wall of the runner body 110, so as to prevent the paddles 121 from entering the mounting holes 113 or the runner body 110. The plurality of mounting holes 113 are disposed such that the plurality of rotor blades 120 are disposed radially with respect to the central axis of the rotor body 110.

Referring to fig. 5, the plurality of operating mechanisms 130 are respectively corresponding to the plurality of mounting holes 113 one by one. The operating mechanism 130 includes a turntable 131, a link 132, and an adapter 133. The turntable 131 is detachably coupled to an end of the corresponding mounting portion 122 and contacts an inner wall of the rotator body 110. The turntable 131 has an eccentric portion 1311 provided radially eccentrically with respect to the mounting hole 113. One end of the link 132 is rotatably connected to the corresponding eccentric portion 1311, and the other end is connected to the adapter 133. In this way, the turntable 131 connected to the end of the mounting portion 122 abuts against the inner wall of the rotor body 110, and the paddle rotor blade 120 is prevented from coming out of the mounting hole 113 during use.

The front operating member 140 is disposed inside the first opening end 111 and is rotatably connected to each of the adapter 133. The front operating member 140 is operable to reciprocate in a direction in which the first open end 111 and the second open end 112 are directed toward each other, so as to drive the rotary disk 131 to rotate about the central axis of the respective mounting hole 113.

Wherein, the direction in which the first open end 111 and the second open end 112 point to each other is parallel to the water flow direction. In practical applications, when the water head and the load change, an external force may be applied to the front operating member 140, so that the front operating member 140 moves in the direction of the first open end 111 pointing to the second open end 112 or the direction of the second open end 112 pointing to the first open end 111 in the rotating wheel body 110, at this time, each connecting rod 132 pulls or pushes the eccentric portion 1311 to move so as to drive the turntable 131 to rotate forward or backward around the central axis of the corresponding mounting hole 113, and each rotating paddle type rotating wheel blade 120 also rotates along with the corresponding turntable 131, so as to realize automatic rotation of the rotating paddle type rotating wheel blade 120.

In the installation process of the rotating blade type rotating wheel 120, only the rotating disc 131 and the structural design of the rotating blade type rotating wheel 120 are needed, the installation of the rotating blade type rotating wheel 120 on the rotating wheel body 110 can be realized, the installation firmness of the rotating blade type rotating wheel 120 on the rotating wheel body 110 is guaranteed, the rotating blade type rotating wheel 120 is set to be a short pivot structure consisting of an installation part 122 and blades 121, the installation part 122 is positioned in a corresponding installation hole 113 and cannot extend into the rotating wheel body 110, the rotating blade type rotating wheel 120 after installation adopts a structure with one supporting point (namely, the supporting point is supported on the outer wall of the rotating wheel body 110), the spherical rotating wheel body core structure positioned in the rotating wheel body 110 is cancelled, the requirement of the rotating blade type rotating wheel 120 on the installation space in the rotating wheel body 110 is small, and the operation space in the rotating wheel body 110 is increased.

Compared with the traditional runner with the runner body core structure inside, the runner body 110 in the embodiment of the utility model has no runner body core structure inside, so that the runner body 110 is of a hollow structure with two open ends, the structure is simplified, the molding difficulty of the runner body 110 is reduced, and the processing cost of the rotating paddle type runner structure 100 is lower.

Therefore, even if the rotor type rotor structure 100 is applied to a small rotor structure with the diameter of the rotor body 110 being smaller than 3 meters, the inner space of the rotor body 110 in the rotor type rotor structure 100 can meet the requirement for the operation space and the requirement for the assembly space by each component in the rotor body 110, so the rotor type rotor structure 100 has the advantages of simple structure, convenient installation and maintenance, low manufacturing cost and the like, and is beneficial to the miniaturization of the rotor type rotor structure 100.

Referring to fig. 1 and 5 again, in some embodiments, a first connecting hole (not shown) is formed at an end of the mounting portion 122 facing the inner end of the rotor body 110. The turntable 131 has a flat plate structure. A second connection hole (not shown) is formed at a position of the turntable 131 opposite to the first connection hole. The operating mechanism 130 also includes a connector 134. One end of the connecting piece 134 is inserted through the second connecting hole, and the other end is connected with the corresponding first connecting hole, so as to detachably connect the turntable 131 with the corresponding mounting portion 122.

Specifically, the first connecting hole is a threaded hole, the second connecting hole is a through hole, the connecting piece 134 is a bolt, one end of the connecting piece 134 is threaded through the second connecting hole, and the other end is screwed into the second connecting hole, so as to detachably connect the turntable 131 and the mounting portion 122. Of course, in other embodiments, the connecting member 134 may be a screw, a nut and screw assembly, or other structure capable of detachably connecting the turntable 131 and the mounting portion 122. In this way, the connection piece 134 is used to detachably connect the turntable 131 and the rotating paddle type rotating blade 120, so as to facilitate the installation and maintenance of the rotating paddle type rotating blade 120.

In some embodiments, adapter 133 is a fork. One end of the fork is detachably connected to the front operating member 140. Both ends of the link 132 are rotatably connected to the other ends of the fork and the eccentric portion 1311 through pins 135, respectively. Thus, through holes or screw holes are formed at both ends of the connecting rod 132, one end of the fork head far from the front operating member 140 and the eccentric portion 1311, and the pin shaft 135 is engaged with the through holes or screw holes to realize rotatable connection.

In some embodiments, the edge of the blade 121 distal from the end of the mounting portion 122 is spherical. The outer edges of the blades 121 are arranged in a spherical shape, so that water flow in a hydraulic channel of the water turbine generates larger thrust to the rotating blade 120, and the improvement of the productivity of the water turbine is facilitated.

Referring to fig. 1, 2 and 6, in some embodiments, the number of mounting holes 113, the rotor blades 120 and the operating mechanism 130 is four. The plurality of mounting holes 113 are uniformly distributed along the circumferential direction of the rotor body 110. The front operating member 140 has a rectangular plate-like structure. One ends of the four adapters 133 are detachably mounted to four corner portions of the front operating member 140, respectively. One end of the adapter 133 is detachably connected to the corner portion of the front-mounted operating member 140, so that the mass of the paddle wheel structure 100 is reduced, and each operating mechanism 130 can be ensured to be as close to the inner wall of the wheel body 110 as possible, so that the operating space and the assembly space in the wheel body 110 are increased, and the miniaturization probability of the paddle wheel structure 100 is further improved.

Of course, in other embodiments, the number of mounting holes 113, rotor blades 120, and operating mechanisms 130 may be two, three, five, etc.

Referring to fig. 1 and 6 again, further, in some embodiments, a supporting member 150 is disposed on an inner wall of the first opening end 111 opposite to each linear edge of the front operating member 140. Therefore, the four straight sides of the front operating element 140 can be supported by the supporting elements 150, and the reciprocating movement path of the front operating element 140 is guided, so that the rotation adjustment process of the rotating paddle type rotating wheel blades 120 is more accurate and stable, and meanwhile, the rotating paddle type rotating wheel structure 100 can be ensured to be lighter, and further miniaturization of the rotating paddle type rotating wheel structure 100 is facilitated.

Specifically, the support 150 extends in a direction in which the first open end 111 and the second open end 112 are directed toward each other. Of course, in other embodiments, the support member 150 may have other shapes, so long as the front operating member 140 is always on the support member 150 while reciprocating in the rotating wheel body 110.

More specifically, two supporting members 150 are provided along each straight side of the inner wall of the rotator body 110 at positions opposite to each straight side of the front operating member 140 at intervals to further improve the smoothness of the front operating member 140 when reciprocating.

Further, in some embodiments, a chamfer is formed at each corner of the front operator 140. The chamfer angle can remove the sharp angle of the front operating member 140, so that each operating mechanism 130 is closer to the inner wall of the runner body 110, and the operating space and the assembly space in the runner body 110 can be further increased while ensuring that the front operating member 140 does not interfere with other parts in the runner body 110.

It should be noted that, in practical application, the above-mentioned chamfering and supporting member 150 may be alternatively or simultaneously used.

Referring again to fig. 1 and 2, in order to prevent water in the hydraulic flow channel from flowing backward into the rotor body 110, in some embodiments, a sealing ring 160 is sleeved on each mounting portion 122. Each seal ring 160 abuts against the wall of the corresponding mounting hole 113. The seal ring 160 is used for sealing the connection between the rotating paddle type rotating wheel blade 120 and the rotating wheel body 110 to isolate water, sediment impurities and the like outside the rotating wheel body 110, and prevent the drinking rust from corroding the components (such as the operating mechanism 130, the front operating member 140 and the like) in the rotating paddle type rotating wheel body 110, so as to prolong the service life of the rotating paddle type rotating wheel structure 100.

Further, in some embodiments, a wear bushing 170 is disposed within each mounting hole 113. The mounting portion 122 rotatably penetrates the wear-resistant bush 170, and slidably contacts the turntable 131 with the wear-resistant bush 170. The wear-resistant lining 170 may be a structure with a wear-resistant polymer material coated on the surface, or may be directly made of a metal material such as copper, copper alloy, gao Meng steel, etc.

The wear-resistant bushing 170 can prevent the mounting portion 122 of the rotating blade 120 from directly contacting with the wall of the mounting hole 113, reduce the wear probability of the rotating blade 120 and the rotating body 110, and facilitate the extension of the service life of the rotating blade structure 100.

Referring again to fig. 2-4, in some embodiments, the mounting portion 122 includes a first shaft section 1221 coupled to the blade 121 and a second shaft section 1222 coupled to an end of the first shaft section 1221 remote from the blade 121. The second shaft section 1222 has a diameter smaller than the diameter of the first shaft section 1221. Thus, the mounting portion 122 has a stepped shaft structure provided along the central axis direction of the mounting hole 113.

The mounting hole 113 includes a first hole section 1131, a second hole section 1132, a third hole section 1133 and a fourth hole section 1134 which are sequentially communicated from inside to outside and sequentially increase in hole diameter.

The sidewalls at both ends of the wear-resistant bushing 170 are bent in a direction away from the central axis of the wear-resistant bushing 170, so that the axial cross section of the wear-resistant bushing 170 is U-shaped. The opening of the U-shape is thus directed away from the central axis of the wear bushing 170. The wear bushing 170 is disposed through the first bore section 1131. The wear-resistant lining 170 may be an integral structure made of elastic material, or may be composed of two sleeves oppositely arranged along the central axis direction of the wear-resistant lining 170.

The second shaft section 1222 rotatably penetrates the wear-resistant bushing 170, and clamps the sidewall of the wear-resistant bushing 170 between the second shaft section 1222 and the wall of the first hole section 1131. The turntable 131 is detachably mounted to an end portion of the second shaft section 1222, and clamps a sidewall of the wear-resistant bushing 170 facing away from one end of the blade 121 between the turntable 131 and an inner wall of the runner body 110.

Therefore, the wear-resistant bushing 170 is set to be in a U-shaped annular structure, and the wear-resistant bushing 170 is arranged in the first hole section 1131 in a penetrating manner, two ends of the wear-resistant bushing 170 are respectively bent and extended to the edge parts of the openings at two ends of the first hole section 1131, so that the turntable 131 and the mounting part 122 can not be directly contacted with the rotating wheel body 110 while the mounting of the wear-resistant bushing 170 is realized, and the abrasion probability of the rotating paddle type rotating wheel structure 100 is further reduced.

The first shaft section 1221 rotatably penetrates the second hole section 1132, the third hole section 1133 and the fourth hole section 1134. The rotor wheel structure 100 further includes a sealing platen (not shown) that is sleeved over each first shaft section 1221. The sealing pressure plate is removably mounted within the corresponding fourth bore section 1134 to press the seal ring 160 within the corresponding third bore section 1133.

Therefore, when the first shaft section 1221 is inserted through the second hole section 1132, the third hole section 1133 and the fourth hole section 1134, an annular installation space for installing the seal ring 160 is formed between the sidewall of the first shaft section 1221 and the inner wall of the third hole section 1133, so as to facilitate the installation of the density ring. And the sealing pressing plate is arranged in the fourth hole section 1134, so that the loosening conditions such as falling off and sliding of the sealing ring 160 can be prevented, and the sealing effect can be improved.

Of course, in other embodiments, the wear-resistant lining 170 may be a straight cylindrical structure, and may be directly clamped between the mounting portion 122 and the inner wall of the mounting hole 113 during mounting; in the installation of the seal ring 160, a clamping groove may be formed in the inner wall of the installation hole 113, and the seal ring 160 may be directly clamped into the clamping groove.

Referring again to fig. 1, based on the same inventive concept, the utility model also provides a shaft extension through-flow turbine. The shaft extension through-flow turbine includes the rotor wheel structure 100, the front main shaft 200, the rear main shaft 300, and the push-pull rod 400 as described above.

The first and second open ends 111 and 112 are hermetically and detachably connected to one end of the front main shaft 200 and one end of the rear main shaft 300, respectively. As such, the sheave body 110 is mounted between the front main shaft 200 and the rear main shaft 300.

The push-pull rod 400 slidably penetrates through the front main shaft 200 and is in sealing contact with the inner wall of the front main shaft 200 near one end of the runner body 110. One end of the push-pull rod 400 extends into the rotating wheel body 110 to be detachably connected with the front operating member 140, and is used for driving the front operating member 140 to reciprocate along the direction that the first opening end 111 and the second opening end 112 point to each other. The push-pull rod 400 is mainly used for transmitting external force to the front operating member 140 so as to realize automatic adjustment of the rotating paddle type runner blade 120.

Of course, the shaft extension type irrigation water turbine also comprises a water inlet pipe, a water guide mechanism, a rotating wheel chamber, an S-shaped draft tube, a bulb body, a front bearing thrust mechanism, a thrust component bearing and an external rotating wheel servomotor. The inlet pipe, the water guide mechanism, the runner chamber and the draft tube are sequentially communicated along the direction that the first opening end 111 points to the second opening end 112 so as to form a hydraulic channel through which water flows. The external turning gear servomotor is used for providing driving force for the push-pull rod 400 to drive the turning paddle turning gear blade 120 to rotate. The bulb, the thrust bearing of the leading bearing, the thrust component bearing and the external rotating wheel servomotor are all conventional designs in the shaft extension through-flow turbine, belong to the prior art and are not repeated here.

Specifically, when the outer edge of the blade 121 at the end remote from the mounting portion 122 is spherical, the inner wall of the rotor chamber is also spherical.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
