Description

Technical Field

[0001] This utility model relates to the field of hydropower equipment technology, and in particular to a combined magnetic levitation water turbine. Background Technology

[0002] A water turbine is a type of power machine that converts the kinetic and potential energy of water flow into mechanical energy. It is used in hydroelectric power plants to drive generators to generate electricity and transmits power through a shaft system.

[0003] In traditional hydro turbines, the rotating and stationary parts are usually connected by mechanical bearings during operation, which presents many problems. After long-term operation, mechanical bearings will generate significant energy loss due to friction, reducing the power generation efficiency of the hydro turbine. At the same time, mechanical bearings require regular maintenance and replacement, increasing the operating cost and maintenance workload of the equipment. In addition, the structure of traditional hydro turbines is relatively fixed, making it difficult to flexibly adjust to different water flow environments and power generation needs, thus limiting their application in the development of diverse hydropower resources.

[0004] To address the above issues, we have developed a combined magnetic levitation water turbine. Utility Model Content

[0005] This utility model discloses a combined magnetic levitation water turbine, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A combined magnetic levitation water turbine includes a base plate and a support plate. The support plate is disposed above the base plate. A water turbine body is fixedly connected to one end of the top of the base plate. A rotor shaft is rotatably connected inside the water turbine body. The water turbine body is fixedly connected to the outside of the rotor shaft. One end of the rotor shaft extends to the outside of the water turbine body and is fixedly connected to a first magnetic levitation unit. A main motor is fixedly connected to the top of the support plate. A connecting shaft is fixedly connected to the output shaft of the main motor. A second magnetic levitation unit is fixedly connected to the end of the connecting shaft away from the main motor. The second magnetic levitation unit works in conjunction with the first magnetic levitation unit.

[0008] When the water flow impacts the turbine body, the turbine body drives the rotor shaft to rotate. At this time, the main motor is started, and the main motor drives the second magnetic levitation unit to rotate through the connecting shaft. The second magnetic levitation unit cooperates with the first magnetic levitation unit and uses the principle of magnetic levitation to reduce the frictional resistance when the rotor shaft rotates, so that the turbine can convert water energy into mechanical energy more efficiently and improve power generation efficiency.

[0009] In a preferred embodiment, a rotor body is fixedly connected to the outside of the rotor shaft and inside the turbine body, a stator winding is provided outside the rotor body, and a stator core is provided outside the stator winding.

[0010] The rotor body interacts with the stator windings and stator core to generate electrical energy based on the principle of electromagnetic induction. The stator windings cut the magnetic lines of force generated by the rotor body, thereby generating an induced electromotive force in the stator windings, and then outputting electrical energy.

[0011] In a preferred embodiment, both the input and output ends of the turbine body are connected to external equipment via flanges.

[0012] The turbine body needs to be connected to the inlet and outlet pipes. Using flanges, the input end of the turbine body can be easily and quickly connected to the inlet pipe, and the output end can be connected to the outlet pipe. Moreover, the flange connection method has good sealing performance and can effectively prevent water leakage.

[0013] In a preferred embodiment, limit slide rails are fixedly connected to both sides of the top of the base plate, and limit blocks are fixedly connected to both sides of the bottom of the support plate, with each limit block slidably connected to the corresponding limit slide rail.

[0014] When it is necessary to fine-tune the alignment of the second magnetic levitation unit with the first magnetic levitation unit, the staff can push the support plate, and the limiting block will slide smoothly along the limiting slide rail, ensuring the accuracy and stability of the support plate movement and avoiding the impact of improper movement on the alignment of the magnetic levitation units.

[0015] In a preferred embodiment, two fixing blocks are fixedly connected to the top of the base plate, a lead screw is rotatably connected between the two fixing blocks, a sliding block is threaded onto the external part of the lead screw, and the sliding block is fixedly connected to the bottom of the support plate.

[0016] When precisely adjusting the gap of the magnetic levitation unit, the support plate can be moved with minimal displacement by slowly rotating the lead screw, ensuring the precision of the magnetic levitation engagement and improving the operating efficiency of the turbine.

[0017] In a preferred embodiment, a drive motor is fixedly connected to one side of one of the fixed blocks, and the output shaft of the drive motor passes through the fixed block and is fixedly connected to one end of the lead screw.

[0018] In the automated operation of hydropower stations, drive motors can automatically rotate lead screws. When it is necessary to adjust the position of the support plate, the drive motor is started through external control equipment. The drive motor drives the lead screw to rotate, which in turn moves the sliding block and the support plate.

[0019] In a preferred embodiment, the main motor, the first magnetic levitation unit, the second magnetic levitation unit, and the drive motor are all electrically connected to an external control device.

[0020] Based on changes in water flow, staff can adjust the speed of the main motor using control equipment to better coordinate with the operation of the water turbine. When an abnormality is detected in the coordination of the magnetic levitation unit, the control equipment can automatically start the drive motor to adjust the position of the support plate, and at the same time adjust the parameters of the first and second magnetic levitation units to ensure that the water turbine is always in a highly efficient and stable operating state.

[0021] The combined magnetic levitation water turbine provided by this utility model has the following advantages:

[0022] In this invention, when water flows and impacts the turbine body 4 inside the turbine body 3, the turbine body 4 drives the rotor shaft 8 to rotate. The main motor 10 drives the second magnetic levitation unit 12 to rotate through the connecting shaft 11. The second magnetic levitation unit 12 cooperates with the first magnetic levitation unit 9 and uses the principle of magnetic levitation to reduce the frictional resistance when the rotor shaft 8 rotates, so that the turbine can convert water energy into mechanical energy more efficiently and improve the power generation efficiency.

[0023] 1. The magnetic levitation support system eliminates friction in mechanical bearings, greatly reduces energy loss, and improves the power generation efficiency of the turbine. Compared with traditional turbines, the power generation efficiency is significantly improved.

[0024] 2. It reduces the maintenance and replacement costs of mechanical bearings. At the same time, the modular structure can be flexibly adjusted according to needs, avoiding the waste of resources caused by over-construction and reducing the overall investment cost.

[0025] 3. The combined connection structure allows the turbine to be flexibly combined into power generation equipment of different scales according to different water flow, head and other hydropower conditions. It is suitable for a variety of hydropower resource development scenarios, improves the versatility and application range of the equipment, and greatly improves the operation quality and efficiency compared with traditional devices.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0033] The combined magnetic levitation water turbine disclosed in this utility model is mainly used in hydropower generation equipment.

[0034] Reference Figures 1-5 A combined magnetic levitation water turbine includes a base plate 1 and a support plate 2. The support plate 2 is disposed above the base plate 1. A water turbine body 3 is fixedly connected to one end of the top of the base plate 1. A rotor shaft 8 is rotatably connected inside the water turbine body 3. A water turbine body 4 is fixedly connected to the outside of the rotor shaft 8. One end of the rotor shaft 8 extends to the outside of the water turbine body 3 and is fixedly connected to a first magnetic levitation unit 9. A main motor 10 is fixedly connected to the top of the support plate 2. A connecting shaft 11 is fixedly connected to the output shaft of the main motor 10. A second magnetic levitation unit 12 is fixedly connected to the end of the connecting shaft 11 away from the main motor 10. The second magnetic levitation unit 12 is used in conjunction with the first magnetic levitation unit 9.

[0035] In this embodiment: when the water flow impacts the turbine body 4 inside the turbine body 3, the turbine body 4 drives the rotor shaft 8 to rotate. At this time, the main motor 10 is started. The main motor 10 drives the second magnetic levitation unit 12 to rotate through the connecting shaft 11. The second magnetic levitation unit 12 cooperates with the first magnetic levitation unit 9. By utilizing the principle of magnetic levitation, the frictional resistance when the rotor shaft 8 rotates is reduced, so that the turbine can convert water energy into mechanical energy more efficiently and improve the power generation efficiency.

[0036] In a preferred embodiment, a rotor body 7 is fixedly connected to the outside of the rotor shaft 8 and inside the turbine body 3. A stator winding 6 is provided outside the rotor body 7, and a stator core 5 is provided outside the stator winding 6.

[0037] In this embodiment, the rotor body 7 interacts with the stator winding 6 and the stator core 5 to generate electrical energy according to the principle of electromagnetic induction. The stator winding 6 cuts the magnetic lines of force generated by the rotor body 7, thereby generating an induced electromotive force in the stator winding 6, and then outputting electrical energy.

[0038] In a preferred embodiment, both the input and output ends of the turbine body 3 are connected to external equipment via flanges 13.

[0039] In this embodiment, the turbine body 3 needs to be connected to the inlet pipe and the outlet pipe. Through the flange 13, the input end of the turbine body 3 can be conveniently and quickly connected to the inlet pipe, and the output end can be connected to the outlet pipe. Moreover, the connection method of the flange 13 has good sealing performance and can effectively prevent water leakage.

[0040] In a preferred embodiment, both sides of the top of the base plate 1 are fixedly connected to limit slide rails 14, and both sides of the bottom of the support plate 2 are fixedly connected to limit blocks 15, with each limit block 15 slidably connected to the corresponding limit slide rail 14.

[0041] In this embodiment, when it is necessary to fine-tune the matching position of the second magnetic levitation unit 12 and the first magnetic levitation unit 9, the staff can push the support plate 2 and the limiting block 15 to slide smoothly along the limiting slide rail 14, which ensures the accuracy and stability of the movement of the support plate 2 and avoids affecting the matching effect of the magnetic levitation unit due to improper movement.

[0042] In a preferred embodiment, two fixing blocks 16 are fixedly connected to the top of the base plate 1, and a lead screw 17 is rotatably connected between the two fixing blocks 16. A sliding block 18 is threaded onto the outside of the lead screw 17, and the sliding block 18 is fixedly connected to the bottom of the support plate 2.

[0043] In this embodiment, when precisely adjusting the gap of the magnetic levitation unit, the support plate 2 can be moved with minimal displacement by slowly rotating the lead screw 17, ensuring the accuracy of the magnetic levitation engagement and improving the operating efficiency of the turbine.

[0044] In a preferred embodiment, a drive motor 19 is fixedly connected to one side of one of the fixing blocks 16, and the output shaft of the drive motor 19 passes through the fixing block 16 and is fixedly connected to one end of the lead screw 17.

[0045] In this embodiment: During the automated operation of the hydropower station, the drive motor 19 can realize the automatic rotation of the lead screw 17. When it is necessary to adjust the position of the support plate 2, the drive motor 19 is started through the external control equipment. The drive motor 19 drives the lead screw 17 to rotate, which in turn drives the sliding block 18 and the support plate 2 to move.

[0046] In a preferred embodiment, the main motor 10, the first magnetic levitation unit 9, the second magnetic levitation unit 12, and the drive motor 19 are all electrically connected to an external control device.

[0047] In this embodiment: Based on the changes in water flow, the operator can adjust the speed of the main motor 10 through the control equipment to better coordinate with the operation of the water turbine. When an abnormality is detected in the coordination of the magnetic levitation unit, the control equipment can automatically start the drive motor 19 to adjust the position of the support plate 2, and at the same time adjust the parameters of the first magnetic levitation unit 9 and the second magnetic levitation unit 12 to ensure that the water turbine is always in a highly efficient and stable operating state.

[0048] Working principle: When water flows through flange 13 into turbine body 3, it drives turbine body 4 to rotate and drives rotor shaft 8 to rotate. Rotor body 7 rotates with rotor shaft 8 and cuts magnetic field lines in the magnetic field formed by stator winding 6 and stator core 5 to generate electricity.

[0049] At the same time, the first magnetic levitation unit 9 rotates synchronously with the rotor shaft 8 and forms a magnetic levitation coupling with the second magnetic levitation unit 12 driven by the main motor 10 through the connecting shaft 11, thereby realizing contactless power transmission.

[0050] The drive motor 19 drives the lead screw 17 to rotate, causing the sliding block 18 to move along the lead screw 17. The precise displacement adjustment of the support plate 2 is achieved through the cooperation of the limit block 15 and the limit slide rail 14, thereby controlling the coupling distance between the second magnetic levitation unit 12 and the first magnetic levitation unit 9, and realizing the efficient combination of hydropower generation and magnetic levitation power transmission.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
