DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the application more clear, the technical scheme in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application.

[0026] The application provides a magnetic coupling driving device, which is mainly used to solve the problem that the heat dissipation of the current magnetic coupling driving device mainly depends on passive and active heat dissipation technologies, the passive heat dissipation technology includes heat dissipation fins and natural convection, and the active heat dissipation technology includes fan heat dissipation and liquid cooling system, the passive heat dissipation efficiency is not high, the material performance is prone to degradation and the magnetic performance is prone to change, and the active heat dissipation needs additional electric energy to drive the heat dissipation equipment, which consumes a large amount of energy, increases the load of the power grid and increases the enterprise cost, and the following technical scheme is provided, which will be described in detail below. Figures 1-8 A magnetic coupling driving device mainly includes a mounting frame 1, a drive motor 2, a permanent magnet rotor 3, a magnetic rotor 4, two shaft connecting rods 5 located on the same straight line and two heat dissipation mechanisms 6, the drive motor 2 is installed on the mounting frame 1, the mounting frame 1 serves as the basic structure of the entire magnetic coupling driving device, and the mounting frame 1 provides a stable support platform, one of the two shaft connecting rods 5 is detachably fixed on the output end of the drive motor 2, and the other shaft connecting rod 5 is detachably and rotatably installed on the mounting frame 1, so as to adapt to different installation requirements and facilitate maintenance, specifically, Figure 3 and Figure 4 ​​​As shown, the output end of the driving motor 2 is provided with a clamping groove, one end of the rotating shaft connecting rod 5 is fixedly provided with a clamping block clamped in the clamping groove, and the clamping block is fixedly provided in the clamping groove through bolts, so that the rotating shaft connecting rod 5 is fixedly connected with the output end of the driving motor 2, which is convenient for disassembly and assembly. The detachable rotating shaft connecting rod 5 makes the installation, disassembly and maintenance process more convenient, reduces the maintenance cost and time, and the permanent magnet rotor 3 and the magnetic guide rotor 4 are respectively fixed on one end of the two rotating shaft connecting rods 5 close to each other, and power transmission is realized through magnetic coupling. Two heat dissipation mechanisms 6 are respectively installed on the two rotating shaft connecting rods 5 and correspond to the permanent magnet rotor 3 and the magnetic guide rotor 4 respectively to realize targeted heat dissipation and prevent overheating. The heat dissipation mechanism 6 includes a first heat dissipation assembly 61 and a second heat dissipation assembly 62. The first heat dissipation assembly 61 and the second heat dissipation assembly 62 are both driven to rotate by the rotating shaft connecting rod 5, which means that the heat dissipation process can directly utilize the rotating energy of the device itself, reducing the dependence on external energy and improving the energy utilization efficiency. By combining passive and active heat dissipation technologies, the magnetic coupling driving device can maintain good heat dissipation performance under different working conditions, thereby improving the overall working performance and reliability.

[0027] Specifically, please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 . The first heat dissipation assembly 61 includes a heat dissipation fan blade 611 sleeved on the rotating shaft connecting rod 5. The heat dissipation fan blade 611 can rotate with the rotation of the rotating shaft connecting rod 5, effectively taking away heat from the heat source area of the magnetic coupling driving device, and improving the heat dissipation efficiency. In order to facilitate the disassembly and maintenance of the heat dissipation fan blade 611, a positioning plate 51 is fixedly sleeved on the rotating shaft connecting rod 5. The positioning plate 51 ensures the accurate position of the heat dissipation fan blade 611. The heat dissipation fan blade 611 is movably sleeved on the rotating shaft connecting rod 5. An external thread 52 is formed on the outer circumferential side of the rotating shaft connecting rod 5. A fastening block 612 is threadedly sleeved on the external thread 52. The fastening block 612 is used to abut the heat dissipation fan blade 611 against the positioning plate 51. By abutting the heat dissipation fan blade 611 against the positioning block 613 and then rotating the fastening block 612 until the fastening block 612 tightly abuts one side of the heat dissipation fan blade 611, the heat dissipation fan blade 611 can be fixed, ensuring that it is firmly fixed and stable even at high speed, reducing the risk of damage caused by vibration or deviation, and facilitating the disassembly of the heat dissipation fan blade 611. Therefore, when replacement or maintenance is required, it can be quickly performed, reducing maintenance cost and downtime. To further ensure the position of the cooling fan blade 611 and reduce its sway during operation, a positioning groove 53 is provided on the outer wall of the rotating shaft connecting rod 5, which passes through one end of the rotating shaft connecting rod 5 and is arranged along the length of the rotating shaft connecting rod 5. A positioning block 613 is constructed on the inner wall of the cooling fan blade 611, which is slidably installed inside the positioning groove 53, thereby guiding and positioning the cooling fan blade 611. Through precise positioning and stable fixing, the service life of the cooling fan blade 611 is extended, thereby improving the overall reliability and performance of the magnetic coupling drive device.

[0028] In this embodiment, please refer to Figure 2 , Figure 6 , Figure 7 and Figure 8 The second heat dissipation assembly 62 includes a liquid cooling box 621, a circulating pump body 622, and a linkage 623. The liquid cooling box 621 is fixed on the mounting bracket 1, and one side of the liquid cooling box 621 is in contact with the side of the permanent magnet rotor 3 or the magnetically conductive rotor 4 facing away from its own magnetic pole. The liquid cooling box 621 in the second heat dissipation assembly 62 is fixed on the mounting bracket 1 to ensure its stability. One side of the cooling box 621 is designed to be in contact with the side of the permanent magnet rotor 3 or the magnetically conductive rotor 4 facing away from its magnetic pole so as to directly absorb the heat generated by the rotor. The circulating pump body 622... 22 includes a sealing housing 6221 mounted on the mounting bracket 1. An impeller 6222 is rotatably mounted inside the sealing housing 6221. The sealing housing 6221 has a liquid inlet and a liquid outlet, and an inlet pipe 6223 and an outlet pipe 6224 are respectively connected to the inlet and outlet. The other ends of the inlet pipe 6223 and the outlet pipe 6224 are connected to the liquid cooling box 621, forming a closed loop. The liquid cooling box 621, the sealing housing 6221, the inlet pipe 6223 and the outlet pipe 6224 are connected to the liquid cooling box 621, forming a closed loop. The interior of 224 is filled with coolant, ensuring the entire system is filled with cooling medium for effective heat exchange. Linkage 623 connects the rotating shaft link 5 to one end of the impeller 6222's shaft, driving the impeller 6222 to rotate. The impeller 6222 pumps the coolant, thus achieving circulation in the liquid cooling system. The direct contact design between the liquid cooling tank 621 and the permanent magnet rotor 3 or the magnetically conductive rotor 4 improves heat exchange efficiency, facilitating the rapid transfer of heat generated by the rotor to the coolant. The design of the circulating pump body 622 and linkage 623 ensures continuous circulation of the coolant in the liquid cooling system, effectively removing heat and maintaining a stable temperature for the magnetically coupled drive device. Linkage 623 utilizes the rotational energy of the rotating shaft link 5 to drive the impeller 6222, meaning the liquid cooling system does not require an external power source, reducing energy consumption. Since the liquid cooling system is integrated with the magnetically coupled drive device, external connections and components are reduced, simplifying maintenance procedures and lowering maintenance costs.

[0029] Further, please refer to Figure 6 , Figure 7 and Figure 8The linkage 623 includes a first bevel gear 6231, a second bevel gear 6232, a mounting rod 6233, and two third bevel gears 6234. The first bevel gear 6231 is fixedly sleeved on the rotating shaft connecting rod 5. One end of the impeller 6222's rotating shaft movably passes through the sealing housing 6221, and the second bevel gear 6232 is fixedly sleeved on one end of the impeller 6222's rotating shaft. The mounting rod 6233 is rotatably mounted on the mounting bracket 1. The two third bevel gears 6234 are respectively fixed on both ends of the mounting rod 6233. One of the third bevel gears 6234... 234 meshes with bevel gear 1 6231, and another bevel gear 3 6234 meshes with bevel gear 2 6232. Through the meshing of bevel gear 1 6231, bevel gear 2 6232, and bevel gear 3 6234, a transmission chain is constructed from the rotating shaft connecting rod 5 to the impeller shaft 6222, realizing the transmission of power. Specifically, when the drive motor 2 drives one of the rotating shaft connecting rods 5 to rotate, under the magnetic coupling of the permanent magnet rotor 3 and the magnetically conductive rotor 4, the two rotating shaft connecting rods 5 rotate synchronously. The rotation of the rotating shaft connecting rod 5 drives the bevel gear 6232. When wheel 6231 rotates, it drives bevel gear 6232 to rotate through the connection of two bevel gears 6234 and mounting rod 6233, thereby realizing the rotation of impeller 6222. The entire liquid cooling system can then circulate. The design of bevel gear 6231, bevel gear 6232, mounting rod 6233, and two bevel gears 6234 provides a compact and efficient power transmission method, accurately transmitting the rotational motion of shaft connecting rod 5 to impeller 6222, thereby driving the circulation of coolant in the liquid cooling system. The bevel gear meshing provides a stable mechanical connection, reducing vibration and noise during high-speed rotation and improving the operational stability of the system. Since the bevel gear transmission chain directly utilizes the rotational energy of shaft connecting rod 5, the circulation pumping process of the liquid cooling system does not require external power input, reducing energy consumption. The design of bevel gear 6231, bevel gear 6232, mounting rod 6233, and two bevel gears 6234 makes the maintenance and replacement of linkage 623 simple, helping to reduce maintenance costs and improve the maintainability of the equipment.

[0030] To improve heat dissipation, please refer to [link / reference]. Figure 6 , Figure 7 and Figure 8The system comprises two symmetrically arranged liquid cooling tanks 621. This symmetrical layout helps to balance the flow of coolant and the distribution of heat, thereby achieving a more uniform cooling effect. A connecting pipe 624 connects the two liquid cooling tanks 621. One end of the inlet pipe 6223 is connected to one of the liquid cooling tanks 621, and one end of the outlet pipe 6224 is connected to the other liquid cooling tank 621. The two liquid cooling tanks 621 are connected by the connecting pipe 624 to form an internal circulation loop. The connecting pipe 624 ensures that the coolant can flow freely between the two liquid cooling tanks 621 to maintain the pressure balance and liquid distribution within the system. This design ensures that the coolant can flow back smoothly after heat exchange and continue its circulation process. By symmetrically arranging the liquid cooling tanks 621 and the connecting pipe 624, uniform distribution and flow of coolant within the system are achieved, thereby providing a uniform cooling effect and avoiding the problem of local overheating. This symmetrical liquid cooling system design helps to improve heat dissipation efficiency, especially under high load operating conditions, and can ensure that the temperature of the magnetically coupled drive device is effectively controlled, thereby improving overall performance and lifespan.

[0031] Furthermore, please refer to Figure 6 and Figure 8 The liquid cooling box 621 has several evenly distributed heat-conducting rolling balls 625 connected to one side of the permanent magnet rotor 3 or the magnetic rotor 4. These balls roll on one side of the rotor, directly contacting its surface, thus facilitating efficient heat transfer from the rotor to the liquid cooling box 621. The heat-conducting rolling balls 625 rapidly transfer the heat generated by the permanent magnet rotor 3 or the magnetic rotor 4 to the liquid cooling box 621 through physical contact, improving heat conduction efficiency. The uniform distribution of the heat-conducting rolling balls 625 ensures that heat from the rotor surface is evenly transferred to the liquid cooling box, avoiding localized overheating and helping to extend the rotor's service life. A heat sink 626 is installed on the side of the liquid cooling box 621 opposite to the heat-conducting rolling balls 625. The installation of the heat sink 626 increases the heat dissipation area of ​​the liquid cooling box 621, improving heat dissipation efficiency and helping to dissipate heat into the environment more quickly.

[0032] It should be noted that you should refer to [link / reference]. Figure 6 The permanent magnet rotor 3 or the magnetic rotor 4 is equipped with heat sink 7 on the side facing away from its own magnetic pole to achieve effective heat conduction. The heat sink 7 can effectively absorb heat from the rotor and quickly dissipate it to the surrounding environment, thereby improving the overall heat dissipation efficiency.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
