[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-Figure 3 As shown, a hydraulic clutch with variable guide vanes comprises an input end housing 1 and an output end housing 2, one side of the input end housing 1 and the output end housing 2 are opened, and the sides of the input end housing 1 and the output end housing 2 are arranged opposite to each other, a connecting ring 3 is arranged between the input end housing 1 and the output end housing 2, and a cavity 1 is formed between the input end housing 1, the output end housing 2 and the connecting ring 3, an input shaft 7 is rotatably arranged on the side of the input end housing 1 away from the output end housing 2, one end of the input shaft 7 located in the input end housing 1 is connected to an input impeller shell 8, and a plurality of input end blades 9 are connected to the inner wall of the input impeller shell 8, an output shaft 11 is rotatably arranged on the side of the output end housing 2 away from the input end housing 1, one end of the output shaft 11 located in the output end housing 2 is connected to an output impeller shell 12, and a plurality of output end blades 13 are connected to the inner wall of the output impeller shell 12, one end of the input impeller shell 8 away from the input shaft 7 is rotatably connected to the connecting ring 3, and one end of the output impeller shell 12 away from the output shaft 11 is rotatably connected to the connecting ring 3. The input impeller shell 8, the output impeller shell 12 and part of the connecting ring 3 are located in the first cavity, and the second cavity is formed between the input impeller shell 8, the output impeller shell 12 and the connecting ring 3. The second cavity is filled with a medium, and the medium added in this embodiment is water.

[0019] like Figure 2 As shown, a central shaft 15 is provided between the input end blade 9 and the output end blade 13, and a plurality of support plates 16 are connected to the outer periphery of the central shaft 15, and the other end of the support plate 16 is connected to the inner side of the connecting ring 3. A mounting cavity 4 is provided in the connecting ring 3, and a bevel gear ring 21 is rotatably provided in the mounting cavity 4. A plurality of rotating shafts 19 are rotatably provided on the connecting ring 3, and the rotating shaft 19 is provided along the radial direction of the connecting ring 3. The portion of the rotating shaft 19 located in the mounting cavity 4 is connected to a bevel gear 20, and the bevel gear 20 meshes with the bevel gear ring 21, and the portion of the rotating shaft 19 located in the connecting ring 3 is provided with a guide vane 23. Figure 3 As shown, the inner end of the guide vane 23 fits with the outer periphery of the central shaft 15, and the outer end of the guide vane 23 fits with the inner side of the connecting ring 3, thereby ensuring sealing.

[0020] The rotating shaft 19 drives one of the rotating shafts 19 to rotate, and the rotating shaft 19 drives the connected bevel gear 20 to rotate, and then drives the meshing bevel gear ring 21 to rotate, and the bevel gear ring 21 drives other meshing bevel gears 20 to rotate, thereby driving all the rotating shafts 19 to rotate synchronously. The rotating shaft 19 drives the guide vane 23 to rotate. When the guide vane 23 rotates to be parallel to the axial direction of the input shaft 7, when the input shaft 7 drives the input end blade 9 to rotate through the input impeller shell 8, the water will rotate with it and flow to the output impeller shell 12. The water with kinetic energy flows to the output impeller shell 12 to drive the output end blade 13 to rotate, thereby driving the output shaft 11 to rotate, and the device plays the role of a hydraulic coupler.

[0021] When the output shaft 11 does not need to rotate, the rotating shaft 19 is driven to rotate to adjust the position of the guide vane 23, so that the guide vane 23 is perpendicular to the axial direction of the input shaft 7, and the side surfaces of adjacent guide vanes 23 are in contact, thereby separating the input end blade 9 from the output end blade 13. At this time, when the input shaft 7 rotates to drive the input end blade 9 in the input impeller shell 8 to rotate, water will not flow into the output impeller shell 12, thereby not driving the output shaft 11 to rotate, and the device plays the role of a hydraulic clutch.

[0022] When the rotation speeds of the input shaft 7 and the output shaft 11 are required to be inconsistent, the rotating shaft 19 is driven to rotate, so that the guide vane 23 rotates a certain angle and is located between the horizontal and vertical positions of the axial direction of the input shaft 7, so that the rotation speeds of the input shaft 7 and the output shaft 11 can be different, and the device plays the role of a hydraulic transmission.

[0023] The switching process only requires supplying electrical energy to the middle variable guide vane mechanism once, and does not require continuous energy supply to maintain its working state.

[0024] Furthermore, a labyrinth seal 22 is provided at the connection between the connecting ring 3 and the input impeller shell 8, and at the connection between the connecting ring 3 and the output impeller shell 12. The labyrinth seal 22 plays a sealing role to prevent leakage of the medium. The labyrinth seal 22 is composed of staggered annular convex strips. The specific structure is that the input impeller shell 8 and one end close to the connecting ring 3, the end of the output impeller shell 12 close to the connecting ring 3, and both ends of the connecting ring 3 are provided with a plurality of parallel annular convex strips, the annular convex strip on the input impeller shell 8 is located between the two annular convex strips on the connecting ring 3, and the annular convex strip on the output impeller shell 12 is located between the two annular convex strips on the connecting ring 3.

[0025] Furthermore, one end of the rotating shaft 19 is rotatably disposed in the central shaft 15. The cross section of the central shaft 15 is a regular octagon, and a rotating bearing is disposed on the outer periphery of the central shaft 15, and the end of the rotating shaft 19 is installed in the rotating bearing.

[0026] Furthermore, a mounting groove 17 is provided at the position where the input end housing 1 is mounted with the input shaft 7, a bearing 18 is provided in the mounting groove 17, and the input shaft 7 is mounted in the bearing 18. The mounting structure of the output shaft 11 is similar. The bearing is provided to reduce the friction between the rotating part and the stationary part, thereby reducing the energy loss.

[0027] Further, a support shaft 10 is provided in the input impeller shell 8, and one end of the input end blade 9 away from the input impeller shell 8 is connected to the outer periphery of the support shaft 10, a support shaft 2 14 is provided in the output impeller shell 12, and one end of the output end blade 13 away from the output impeller shell 12 is connected to the outer periphery of the support shaft 2 14, and support ends 24 are provided at both ends of the central shaft 15, and the support shaft 10 and the support shaft 2 14 are respectively rotatably connected to the support ends 24 at both ends of the central shaft 15. Support bearings are respectively provided between the support shaft 10 and the support end 24, and between the support shaft 2 14 and the support end 24, and the support shaft 2 14 plays a supporting role in the rotation of the support shaft 10 and the support shaft 2 14, so as to ensure that the input end blade 9 and the output end blade 13 can rotate smoothly.

[0028] Furthermore, through holes are provided in the support shaft 1 10 , the central shaft 15 , and the support shaft 2 14 , and the through holes penetrate the support shaft 1 10 , the central shaft 15 , and the support shaft 2 14 .
