Description

Technical Field

[0001] This invention relates to the field of permanent magnet speed controller technology, specifically a high-stability mobile base type permanent magnet speed controller that facilitates heat dissipation. Background Technology

[0002] A permanent magnet speed controller is a motor-driven transfer device. Through the coupling of a conductor rotor and a permanent magnet rotor, it can not only transmit torque but also block vibrations generated at the load end during operation. The speed controller achieves conversion efficiency by adjusting the air gap between the conductor rotor and the permanent magnet rotor. Current methods for adjusting the air gap involve mounting the motor on a movable base. Adjusting the motor's position via the base moves the conductor rotor, thus adjusting the air gap. However, the movable base results in static friction, leading to wear. Severe wear exacerbates vibrations during sliding adjustments and motor operation, amplifying noise. Furthermore, the high-speed rotation of the permanent magnet speed controller generates significant heat. If this heat is not dissipated promptly, the magnets in the permanent magnet rotor may demagnetize due to high temperatures. Therefore, heat dissipation is necessary to ensure the normal operation of the permanent magnet speed controller. Summary of the Invention

[0003] The technical problem this invention aims to solve is that when adjusting the position of the motor via the base to change the air gap of the permanent magnet speed controller, the base slides and wears, leading to increased gaps in related structures, amplified vibrations, and increased noise. Simultaneously, the high-speed operation of the permanent magnet speed controller, lacking heat dissipation, results in high temperatures, causing demagnetization of the permanent magnet rotor and affecting its normal operation. To address these problems, this invention proposes a highly stable mobile base-type permanent magnet speed controller with easy heat dissipation. It includes a motor, a conductor rotor, and a permanent magnet rotor. The motor shaft is connected to the conductor rotor, and the load shaft is connected to the permanent magnet rotor. The conductor rotor and permanent magnet rotor are coupled to form the permanent magnet speed controller. The device also includes a base, a drive mechanism, and a heat dissipation mechanism. The base includes an upper base, a lower base, and multiple linear guides. The upper and lower bases are connected by the linear guides, and the upper base can slide on the lower base. The motor is connected to the upper base, the drive mechanism is mounted on the lower base, and the moving block of the drive mechanism is connected to the upper base. The heat dissipation mechanism is located on the outside of the permanent magnet speed controller.

[0004] The technical solution of this invention features a water-cooled heat dissipation cavity that encloses the permanent magnet speed controller. This facilitates cooling water spraying and also protects the speed controller from interference with its normal operation. The water inlet pipe in the water-cooled system introduces cooling water into the heat dissipation cavity via branch pipes, spraying heat from the speed controller and removing the heat generated during operation. The branch pipes of the inlet pipe are positioned at different locations on the speed controller, ensuring even cooling and preventing uneven heat dissipation that could lead to overheating. The voltage stabilizing component in the water-cooled system ensures that the air pressure inside the heat dissipation cavity remains consistent with the external pressure, preventing any impact on the speed controller's conversion efficiency. An air filter inside the voltage stabilizing component prevents dust and other contaminants from entering the heat dissipation cavity. In contrast, the air-cooled system utilizes heat sinks to increase the heat dissipation area and guide fan blades to accelerate airflow, creating a cooling duct. The combination of these elements achieves efficient heat dissipation. A protective frame surrounds the speed controller, providing protection. The upper and lower bases are connected by multiple linear guides. The linear guides use rolling friction, which greatly reduces wear and extends service life. At the same time, the tolerances between the internal structures of the linear guides are small, and with minimal wear, the gaps between the structures are always very small. The upper base is less likely to wobble in other directions when moving, which can reduce vibration and thus reduce noise.

[0005] In a preferred embodiment of the present invention, both the upper surface of the upper base and the lower surface of the lower base are provided with pads. The side wall of the upper base is provided with a fixing component for connecting the motor, and the lower base is provided with a base for a linear guide rail. The side wall of the lower base is provided with scale lines, and the side wall of the upper base is provided with a pointer that mates with the scale lines. The pads can reduce wear on the upper and lower bases, thereby extending the service life of the bases. After the pads are worn out, only a new pad needs to be replaced for continued use. The fixing component is used to connect the motor to the upper base, and the base provides an installation position for the linear guide rail.

[0006] In a preferred embodiment of the present invention, the base is further provided with a mechanical limiting mechanism, which includes a limiting block and a limiting plate. The limiting block is disposed on the lower base, and the limiting plate is disposed on the lower surface of the upper base. There are two limiting plates, and the limiting block is located between the two limiting plates. The limiting block is made of polyurethane. The mechanical limiting mechanism limits the maximum movement distance of the motor by means of the cooperation between the limiting block and the limiting plate, preventing excessive motor displacement and damage to other structures. Polyurethane is a non-rigid material, which can play a certain buffering role when the motor moves the maximum distance.

[0007] In a preferred embodiment of the present invention, the lower base is further provided with a locking member for temporarily locking the base. The locking member is used to lock the upper base under special circumstances to prevent the upper base from shifting.

[0008] In a preferred embodiment of the present invention, the driving mechanism includes a connecting flange, a rotating shaft, a fixed bearing, a coupling, a lead screw, and a support bearing. One end of the rotating shaft is connected to the connecting flange, which is used to connect to an external actuator. The other end of the rotating shaft passes through the fixed bearing, which is mounted on the lower base. Both ends of the lead screw pass through the support bearing, which is mounted on the lower base. One end of the lead screw extends out of the fixed bearing and is connected to the rotating shaft via the coupling. The moving block meshes with the lead screw.

[0009] In a preferred embodiment of the present invention, the heat dissipation mechanism includes a heat dissipation cavity, two drain pipes, two inlet pipes, and a voltage stabilizing component. The permanent magnet speed regulator is disposed inside the heat dissipation cavity. The two drain pipes are located on both sides of the bottom of the heat dissipation cavity, and the two inlet pipes are located on both sides of the front outer wall of the heat dissipation cavity. The two inlet pipes are interconnected. The voltage stabilizing component is disposed on the top of the heat dissipation cavity. The heat dissipation cavity encloses the permanent magnet speed regulator, facilitating spray cooling and protecting the permanent magnet speed regulator from external influences on the conductor rotor or permanent magnet rotor. To prevent disruption to normal operation, the drain pipe is used to discharge cooling water from the heat dissipation chamber, avoiding water accumulation and water resistance. The inlet pipe is used to introduce cooling water into the heat dissipation chamber for spray cooling of the permanent magnet speed controller. Two inlet and two drain pipes are provided, which can be easily installed and connected regardless of which side the water source is located on. The two inlet pipes are interconnected, so as long as one inlet pipe is connected to the water source, both inlet pipes can work. The voltage stabilizing component is used to regulate the air pressure in the heat dissipation chamber to avoid pressure difference, which would lead to energy loss.

[0010] In a preferred embodiment of the present invention, the water inlet pipeline includes a main pipe, a first secondary pipe, a second secondary pipe, a sampling valve, a first valve, and a second valve. The main pipe is connected to the heat dissipation cavity via a branch pipe. Both the first and second secondary pipes are connected to the main pipe and are connected to the heat dissipation cavity via branch pipes. The sampling valve is located on the main pipe, the first valve is located on the first secondary pipe, and the second valve is located on the second secondary pipe. All branch pipes are directly opposite the permanent magnet speed controller. The main pipe, the first secondary pipe, and the second secondary pipe can spray cooling water to different positions of the permanent magnet speed controller, thereby achieving uniform spray heat dissipation. The sampling valve can extract a portion of the cooling water to test its quality, preventing poor-quality cooling water from affecting the relevant structure of the permanent magnet speed controller after spraying. The sampling valve can also be connected to a pressure stabilizing component via a flexible hose, allowing a portion of the cooling water to be introduced into the heat dissipation cavity from the pressure stabilizing component and sprayed onto the permanent magnet speed controller from top to bottom for heat dissipation.

[0011] In a preferred embodiment of the present invention, the voltage stabilizing component includes a vent pipe, a liquid inlet valve, and an air filter. The vent pipe is located at the top of the heat dissipation chamber, and the air filter is installed on the vent pipe. The liquid inlet valve is also installed on the vent pipe. The liquid inlet valve is connected to a sampling valve via a detachable hose. The vent pipe is connected to the outside environment, which allows the air pressure inside the heat dissipation chamber to be consistent with that of the outside environment. The air filter can prevent dust and other external particles from entering the heat dissipation chamber. The liquid inlet valve can introduce cooling water through a pipe, which is sprayed onto the permanent magnet speed controller from above to dissipate heat.

[0012] In a preferred embodiment of the present invention, the heat dissipation mechanism includes a guide fan blade, a heat sink, and a protective frame. The guide fan blade is disposed on the end face of the conductor rotor, the heat sink is disposed in a ring on the side wall of the conductor rotor, and the protective frame is covered above the permanent magnet speed regulator. The guide fan blade rotates together with the conductor rotor, which can accelerate the airflow and form a heat dissipation channel, thereby improving the heat dissipation efficiency. The heat sink increases the heat dissipation area and improves the heat dissipation efficiency. The protective frame is used to protect the normal rotation of the conductor rotor and the permanent magnet rotor and avoid external interference.

[0013] In a preferred embodiment of the present invention, heat dissipation fins are provided on the surface of the heat sink, and the heat sink is made of aluminum. The heat dissipation fins can increase the contact area with the atmosphere, thereby improving the heat dissipation efficiency. Aluminum has a low density, which can reduce the weight of the heat sink and avoid interference with the copper ring in the conductor rotor, thus avoiding affecting the conversion efficiency of the permanent magnet speed controller.

[0014] The beneficial effects of this invention compared to the prior art are: The technical solution of this invention features a water-cooled heat dissipation cavity that encloses the permanent magnet speed controller. This facilitates cooling water spraying and also protects the speed controller from interference with its normal operation. The water inlet pipe in the water-cooled system introduces cooling water into the heat dissipation cavity via branch pipes, spraying heat from the speed controller and removing the heat generated during operation. The branch pipes of the inlet pipe are positioned at different locations on the speed controller, ensuring even cooling and preventing uneven heat dissipation that could lead to overheating. The voltage stabilizing component in the water-cooled system ensures that the air pressure inside the heat dissipation cavity remains consistent with the external pressure, preventing any impact on the speed controller's conversion efficiency. An air filter inside the voltage stabilizing component prevents dust and other contaminants from entering the heat dissipation cavity. In contrast, the air-cooled system utilizes heat sinks to increase the heat dissipation area and guide fan blades to accelerate airflow, creating a cooling duct. The combination of these elements achieves efficient heat dissipation. A protective frame surrounds the speed controller, providing protection. The upper and lower bases are connected by multiple linear guides. The linear guides use rolling friction, which greatly reduces wear and extends service life. At the same time, the tolerances between the internal structures of the linear guides are small, and with minimal wear, the gaps between the structures are always very small. The upper base is less likely to wobble in other directions when moving, which can reduce vibration and thus reduce noise. Attached Figure Description

Detailed Implementation

[0016] The following will refer to the appendices in the embodiments of the present invention. Figure 1-11 The technical solutions in the embodiments of the present invention will be described in detail below. Example 1

[0017] like Figure 1-8 As shown, this embodiment is a water-cooled spray heat dissipation high-stability mobile base type permanent magnet speed controller, including a base 1, a drive mechanism 2, a motor 3, a conductor rotor 4, a permanent magnet rotor 5, and a heat dissipation mechanism 6.

[0018] The conductor rotor 4 and the permanent magnet rotor 5 are coupled together. The permanent magnet speed controller formed by the combination of the conductor rotor 4 and the permanent magnet rotor 5 is the prior art. Both the end faces of the conductor rotor 4 and the permanent magnet rotor 5 are opened. The conductor rotor 4 is connected to the motor shaft of the motor 3 through a coupling, and the permanent magnet rotor 5 is connected to the load shaft through a coupling.

[0019] The motor 3 is mounted on the base 1. The motor is a prior art technology. When the motor 3 works, it can drive the conductor rotor 4 to rotate. The torque is transmitted to the permanent magnet rotor 5 using the principle of electromagnetic induction. The base 1 can move, so the motor 3 can also move, thereby adjusting the air gap between the conductor rotor 4 and the permanent magnet rotor 5 to achieve the purpose of speed regulation.

[0020] The base 1 includes an upper base 11, a lower base 12, and multiple linear guide rails 13.

[0021] The upper base 11 is a flat plate, and the surface of the upper base 11 is fixed with a pad 19 by bolts. The pad 19 can prevent the motor 3 from directly causing wear on the upper base 11.

[0022] Multiple fasteners 15 are provided on the four sides of the upper base 11. The fasteners 15 are used to connect the motor 3 and the upper base 11. In this embodiment, the fasteners 15 include a fixing plate and multiple bolts. The fixing plate is attached to both the motor 3 and the side wall of the upper base 11. The bolts pass through the fixing plate and are connected to the motor 3 and the upper base 11 respectively.

[0023] The lower base 12 is an open-top box that is fixed to the cement base with expansion bolts. The lower surface of the lower base 12 is also fixed with a pad 19 by bolts to reduce the wear of the cement base on the lower base 12. The position of the lower base 12 is fixed, while the upper base 11 moves to adjust the position of the motor 3.

[0024] Multiple bases 14 are fixed inside the lower base 12 by bolts. The bases 14 are fixed to the linear guide rail 13 by bolts. In this embodiment, the linear guide rail 13 is a roller type linear guide rail, which can be purchased directly from the market.

[0025] The linear guide 13 uses rolling friction, which reduces friction, wear, and energy loss, thereby lowering production costs. Furthermore, the linear guide 13 has high precision, achieving micron-level positioning accuracy. Therefore, when the motor 3 is adjusted via the base 1, its adjustment accuracy is also very high.

[0026] The tolerances of the internal structure of the linear guide 13 can be made very small, and due to the use of rolling friction, the friction loss during movement is also relatively small. Therefore, when the linear guide 13 is working, the gaps between the internal structures are small, which can reduce vibration and thus reduce noise.

[0027] The internal structure of the linear guide 13 includes a guide rail and a slider. The guide rail is connected to the base 14, and the slider is connected to the upper base 11 by bolts, so the upper base 11 can be displaced.

[0028] The base 1 also includes a mechanical limiting mechanism, which includes a limiting block 16 and a limiting plate 17. The lower surface of the upper base 11 is provided with two parallel limiting plates 17. The limiting plates 17 are connected to the upper base 11 by bolts. The limiting block 16 is fixedly installed inside the lower base 12 by bolts.

[0029] The limiting block 16 is located between the two limiting plates 17. Through the cooperation of the two limiting plates 17 and the limiting block 16, the maximum movement distance of the upper base 11 can be limited to prevent excessive displacement and damage to other components.

[0030] The limiting block 16 is made of polyurethane. When the upper base 11 moves the maximum distance, the limiting plate 17 and the limiting block 16 will fit together. At this time, the limiting block 16 can produce a certain deformation, thereby playing a buffering role.

[0031] The lower base 12 has scale lines engraved on one side surface, and a small pointer is fixed to the same side surface of the upper base 11 by bolts. The pointer and the scale lines can be used to read the distance that the upper base 11 slides along the lower base 12.

[0032] Furthermore, the base 1 also includes a plurality of locking members 18 that can temporarily lock the upper base 11 and the lower base 12. The locking members 18 are disposed on the side wall of the lower base 12. The locking members 18 include a locking plate and a plurality of bolts. The locking plate is in contact with both the upper base 11 and the lower base 12. The plurality of bolts pass through the locking plate and are then connected to the upper base 11 and the lower base 12 respectively.

[0033] The locking element 18 works in two situations: when the base 1 is being transported, to prevent displacement between the upper base 11 and the lower base 12, the locking element 18 is used to secure them tightly; when the permanent magnet speed controller needs to be disassembled for maintenance, the motor shaft and load shaft of the junction 3 can be temporarily connected directly through the coupling to continue production activities and prevent production interruption and losses.

[0034] In both of the above cases, the purpose of using the locking element 18 is to prevent relative displacement between the upper base 11 and the lower base 12. In other cases, the locking element 18 needs to be removed to facilitate the movement and adjustment of the upper base 11, thereby achieving the adjustment of the position of the motor 3.

[0035] The drive mechanism 2 includes a connecting flange 21, a rotating shaft 22, a fixed bearing 23, a coupling 24, a lead screw 25, a moving block 26, and a support bearing 27.

[0036] Two support bearings 27 are provided. Each support bearing 27 includes a bearing and a fixed seat. The bearing is installed in the middle of the fixed seat, and the fixed seat is fixed to the lower base 12 by bolts. Therefore, the support bearing 27 is installed on the lower base 12.

[0037] Both ends of the lead screw 25 pass through the support bearings 27 and are fixedly connected to the support bearings 27. Therefore, the lead screw 25 is installed inside the lower base 12 through the support bearings 27. The moving block 26 meshes with the lead screw 25 and is located between the two support bearings 27. The moving block 26 is connected to the upper base 11 by bolts. When the lead screw 25 rotates, it can drive the moving block 26 to move, thereby realizing the movement of the upper base 11.

[0038] The fixed bearing 23 also includes a bearing and a fixed seat. The bearing is installed in the middle of the fixed seat, and the fixed seat is fixed to the lower base 12 by bolts. The fixed bearing 23 is then installed on the lower base 12. The fixed bearing 23 is opposite to the support bearing 27 and is located at the inner edge of the lower base 12.

[0039] The rotating shaft 22 passes through the fixed bearing 23 and is fixed. One end of the rotating shaft 22 is located inside the lower base 12 and is connected to the lead screw 25 through the coupling 24. The coupling 24 is a prior art. In this embodiment, the coupling 24 that connects the lead screw 25 and the rotating shaft 22 is a plum blossom coupling.

[0040] The other end of the rotating shaft 22 extends out of the lower base 12 and is fixed to the connecting flange 21. The connecting flange 21 is used to connect to an external actuator. The external actuator drives the rotating shaft 22 to rotate, which in turn drives the lead screw 25 to rotate, thereby realizing the movement of the upper base 11. In this embodiment, the external actuator can be a servo motor. The motor shaft of the servo motor is fixed to the connecting flange 21 by bolts through a flange coupling.

[0041] When a servo motor is used as an external structure, the number of rotations of the servo motor is controllable, so the number of rotations of the lead screw 25 can also be controlled, and the moving distance of the moving block 26 is controllable, so the moving distance of the upper base 11 can be precisely adjusted.

[0042] Of course, when motor 3 is a small motor, it can also be used manually as an external actuator to drive the drive mechanism 2 to rotate in reverse.

[0043] The specific method is as follows: a crank can be set up and fixed to the connecting flange 21 with bolts. By manually turning the crank, the lead screw 25 can be driven to rotate, thereby realizing the movement of the upper base 11. At this time, the scale line and pointer are required to determine the specific movement distance. Compared with the servo motor, the manual method has lower accuracy, but it can reduce the cost of use.

[0044] The specific external actuator to be used will be determined based on the actual situation and production needs.

[0045] The heat dissipation mechanism 6 in this embodiment is a water-cooled spray heat dissipation mechanism. The heat dissipation mechanism 6 in this embodiment includes a heat dissipation cavity 61, two drainage pipes 62, two water inlet pipes 63, and a voltage stabilizing component 64.

[0046] The heat dissipation cavity 61 includes an upper box and a lower box. The upper box and the lower box are connected by fitting together and fixing them with bolts. The heat dissipation cavity 61 is formed by the combination of the upper box and the lower box. The permanent magnet speed controller is located in the heat dissipation cavity 61, and the motor shaft and the load shaft extend into the heat dissipation cavity 61.

[0047] Semi-circular notches are opened on both the front and rear surfaces of the upper and lower boxes, and the notches of the upper and lower boxes fit together to form a through hole. The motor shaft and the load shaft extend into the heat dissipation cavity 61 through the hole to connect with the permanent magnet speed controller. A sealing gasket is provided on the surface of the upper and lower boxes that fit together.

[0048] The voltage regulator 64 is used to regulate the air pressure in the heat dissipation cavity 61, so that the air pressure in the heat dissipation cavity 61 is consistent with the outside air pressure, and to avoid the generation of air pressure difference in the heat dissipation cavity 61 when the permanent magnet speed controller rotates at high speed, thereby affecting the conversion efficiency.

[0049] The voltage stabilizing component 64 includes a ventilation pipe 640 and an air filter 642. The ventilation pipe 640 is installed on the top of the heat dissipation cavity 61 and communicates with the inner cavity of the heat dissipation cavity 61. The air filter 642 is installed at the top of the ventilation pipe 640. The air filter 642 is existing technology and can prevent external dust and other impurities from entering the heat dissipation cavity 61 and affecting the normal operation of the permanent magnet speed regulator.

[0050] The lower end of the ventilation duct 640 is located directly above the permanent magnet speed controller. Two liquid inlet valves 641 are also installed on the ventilation duct 640. The liquid inlet valves 641 are existing technology and are used to introduce cooling water and spray it from top to bottom to dissipate heat from the permanent magnet speed controller. The liquid inlet valves 641 are located on both sides of the ventilation duct 640.

[0051] The heat dissipation cavity 61 is also equipped with an arc-shaped guide plate. The guide plate is located directly below the ventilation duct 640 and above the permanent magnet speed controller. The guide plate is connected to the inner wall of the heat dissipation cavity 61 through a connecting plate. The guide plate, the connecting plate and the heat dissipation cavity 61 are an integral structure. After the cooling water enters the heat dissipation cavity 61 through the inlet valve 641, it is guided by the guide plate to flow to both sides, and then drips onto the permanent magnet speed controller. This prevents the cooling water from being affected by the rotation of the permanent magnet speed controller and falling directly into the bottom of the heat dissipation cavity 61 without contacting the permanent magnet speed controller, thus reducing the heat dissipation efficiency.

[0052] The drainage pipe 62 and the water inlet pipe 63 are combined to form a water-cooled spray mechanism. There are two sets of water-cooled spray mechanisms. Both sets of water-cooled spray mechanisms are installed on the front wall of the heat dissipation cavity 61 and located on both sides of the heat dissipation cavity 61. Therefore, in actual production, no matter which side of the device the water source is located on, the water source can be easily connected to the water inlet pipe 63. Specifically, a water pump can be used to draw cooling water from the water source and enter the water inlet pipe 63 through the pipe.

[0053] The drain pipe 62 is connected to the bottom of the lower box. The drain pipe 62 is used to drain the cooling water dripping during spray cooling. The drain pipe 62 can also be connected to a water source so that the cooling water dripping after spraying can return to the water source and continue to participate in the circulation after the temperature drops, so as to carry out spray cooling.

[0054] The water inlet pipes 63 in the two sets of water-cooled spray mechanisms are interconnected. Therefore, no matter which side of the water inlet pipe 63 is connected to the water source, the cooling water can fill the water inlet pipes 63 in both sets of water-cooled spray mechanisms, which facilitates heat dissipation through spraying.

[0055] The water inlet pipe 63 includes a main pipe 630, a first secondary pipe 631 and a second secondary pipe 632. Both the first secondary pipe 631 and the second secondary pipe 632 are connected to the main pipe 630. The main pipe 630, the first secondary pipe 631 and the second secondary pipe 632 are all mounted on the surface of the heat dissipation cavity 61 by means of brackets. The brackets are connected to the surface of the heat dissipation cavity 61 by bolts or other means.

[0056] The main pipes 630 of the two water inlet pipes 63 are interconnected, thus realizing the interconnection of the two water inlet pipes 63. That is, the main pipes 630 of the two water inlet pipes 63 are one pipe. The main pipe 630 is connected to the lower box through a branch pipe. The branch pipe is located in the middle of the main pipe 630, that is, the branch pipe is located in the middle of the heat dissipation cavity 61. The branch pipe is directly facing the end face of the permanent magnet rotor 5 of the permanent magnet speed controller. Through the spray of cooling water, the end face of the permanent magnet speed controller can be directly cooled. In addition, since the end faces of the permanent magnet rotor 5 and the conductor rotor 4 are both perforated, some cooling water can also pass through the permanent magnet rotor 5 and spray the conductor rotor 4 for cooling.

[0057] The main pipe 630 is equipped with a sampling valve 633, which is existing technology. By opening the sampling valve 633, some cooling water can be released. The cooling water can be collected in a container and the water quality can be tested. When the water quality is found to be poor, the cooling water in the water source needs to be replaced in time to avoid affecting the permanent magnet speed controller.

[0058] In addition, since there are two sampling valves 633, one of the sampling valves 633 can be connected to the liquid inlet valve 641 in the voltage regulator assembly 64 through a detachable hose. In this way, cooling water can flow through the hose to the liquid inlet valve 641 and then be sprayed into the heat dissipation cavity 61 through the ventilation pipe 640, spraying heat to the side wall of the permanent magnet speed controller from top to bottom.

[0059] At this time, the sampling valve 633 on the other side is closed. It is opened when water quality needs to be tested, and only a small amount of cooling water is needed. This amount of cooling water is very small and will not affect the normal spray cooling. The water quality testing process can be completed online without turning off the spray cooling and affecting the normal operation of the cooling mechanism 6.

[0060] The first secondary pipe 631 in both water inlet pipes 63 is connected to the heat dissipation cavity 61 through branch pipes. These two branch pipes are symmetrically distributed on both sides of the front wall of the heat dissipation cavity 61, and these two branch pipes are directly opposite the air gap between the conductor rotor 4 and the permanent magnet rotor 5. When the cooling water is sprayed, it directly dissipates heat at the coupling position of the conductor rotor 4 and the permanent magnet rotor 5.

[0061] Each of the first secondary pipes 631 is equipped with a first valve 634. The opening and closing of the first valve 634 can be used to adjust whether the first secondary pipe 631 needs to spray for heat dissipation. At the same time, the opening of the first valve 634 is adjustable. Adjusting the opening of the first valve 634 can adjust the amount of cooling water sprayed in the first secondary pipe 631. The larger the opening of the first valve 634, the more cooling water is sprayed, and the higher the heat dissipation efficiency.

[0062] The second auxiliary pipe 632 in both water inlet pipes 63 is connected to the heat dissipation cavity 61 through branch pipes. These two branch pipes are symmetrically distributed on both sides of the front wall of the heat dissipation cavity 61, and these two branch pipes are also facing the end face of the permanent magnet rotor 5, directly spraying heat to the end face of the permanent magnet speed controller. However, the position is different from that of the other branch pipes mentioned above, so that different positions can be sprayed for heat dissipation to avoid uneven heat dissipation.

[0063] Each secondary pipe 632 is equipped with a second valve 635. The opening and closing of the second valve 635 can be used to adjust whether the secondary pipe 632 needs to spray for heat dissipation. At the same time, the opening of the second valve 635 is adjustable. By adjusting the opening of the first valve 634, the amount of cooling water sprayed in the secondary pipe 632 can be adjusted. The larger the opening of the second valve 635, the more cooling water is sprayed, and the higher the heat dissipation efficiency.

[0064] The main pipe 630 is always in operation. The first auxiliary pipe 631 and the second auxiliary pipe 632 can work simultaneously. Alternatively, by closing the first valve 634 on the first auxiliary pipe 631 or the second valve 635 on the second auxiliary pipe 632, only a portion of the pipes of the first auxiliary pipe 631 and the second auxiliary pipe 632 can be sprayed for heat dissipation. Furthermore, the opening degree of the first valve 634 and the second valve 635 can be adjusted according to the actual heat dissipation needs, thereby adjusting the spray volume of cooling water.

[0065] The opening of the sampling valve 633 is also adjustable. That is, the amount of water sprayed from the top of the permanent magnet speed controller to its side wall for heat dissipation can also be adjusted. When needed, the two sampling valves 633 can be connected to the two liquid inlet valves 641 through hoses to increase the spray volume and thus improve the heat dissipation efficiency. The specific adjustment needs to be based on the actual heat dissipation requirements. This way, while meeting the heat dissipation requirements, resource waste can be reduced.

[0066] Furthermore, the two inlet valves 641 are not located at the same height. Therefore, when only one inlet valve 641 is involved in heat dissipation, the sprayed cooling water will contact the inner wall of the ventilation pipe 640 and then fall downward into the heat dissipation cavity 61, without directly targeting the other inlet valve 641, thus avoiding damage to the other inlet valve 641.

[0067] The following is a method for using a high-stability mobile base type permanent magnet speed controller that facilitates heat dissipation, as described in this embodiment: After the device is assembled, the external actuator drives the drive mechanism 2 to work. The rotating shaft 22 rotates, which drives the lead screw 25 to rotate together. The moving block 26 moves on the lead screw 25, which synchronously drives the upper base 11 to move. Therefore, the motor 3 can move to realize the adjustment of the air gap of the permanent magnet speed regulator.

[0068] When the permanent magnet speed controller is working, it needs to be cooled. The specific method is as follows: First, connect the main pipe 630 of one side of the water inlet pipe 63 to the water source, and close the main pipe 630 on the other side. Close the sampling valve 633 on one side, and then connect the sampling valve 633 on the other side to the inlet valve 641 through a hose. A water pump draws cooling water from the water source into the main pipe 630, gradually filling it. Simultaneously, the cooling water is diverted into the two secondary pipes 631 and 632, and also flows from the sampling valve 633 on the other side into the hose. Cooling water enters the heat dissipation chamber 61 from different positions, spraying it to cool different parts of the permanent magnet speed controller from all angles, thus avoiding uneven heat dissipation. At the same time, depending on the speed of the permanent magnet speed controller, the opening of the sampling valve 633, the first valve 634 and the second valve 635 connected to the hose can be adjusted appropriately, or some valves can be closed directly, depending on the speed of the permanent magnet speed controller, while ensuring sufficient heat dissipation. This can save resources and reduce production costs. The cooling water dripping from the spray will be discharged from the heat dissipation chamber 61 through the drain pipe 62, avoiding the accumulation of cooling water and the generation of water resistance.

[0069] During heat dissipation, a portion of the cooling water can be released by opening and closing the sampling valve 633. After that, the sampling valve 633 is closed, and the released cooling water is collected in a container to test the water quality. If the water quality is found to be poor, the cooling water in the water source needs to be replaced. In the subsequent water-cooled spray heat dissipation process, clean cooling water is used to flush the permanent magnet speed controller to avoid the impact of the previously poor-quality cooling water on the permanent magnet speed controller.

[0070] When the permanent magnet speed controller is damaged and needs repair, the permanent magnet speed controller and the heat dissipation mechanism 6 are disassembled, the position of the motor 3 is adjusted through the base 1, and the motor shaft and the load shaft are directly connected through the coupling. Then, the upper base 11 and the lower base 12 are fixed with the locking piece 18, and the base 1 can no longer slide. At this time, the motor 3 can temporarily drive the load to work, which can ensure that production activities continue to proceed and avoid huge losses. Example 2

[0071] like Figure 9-11 As shown, this embodiment is a high-stability mobile base type permanent magnet speed controller with air cooling. The difference between this embodiment and embodiment 1 is the heat dissipation structure 6. In this embodiment, the heat dissipation mechanism 6 is air-cooled and includes a guide fan blade 65, a heat sink 66 and a protective frame 67.

[0072] The guide fan blade 65 is installed on the end face of the conductor rotor 4. At the same time, the guide fan blade 65 is also connected to a baffle. The baffle is parallel to the end face of the conductor rotor 4. The guide fan blade 65 is located between the end face of the conductor rotor 4 and the baffle. Since both the end faces of the conductor rotor 4 and the permanent magnet rotor 5 have openings, when the conductor rotor 4 rotates, it will drive the guide fan blade 65 to rotate, thereby accelerating the airflow speed and forming an air duct through the openings.

[0073] Air flows from the load side, through the openings on the conductor rotor 4 and the permanent magnet rotor 5, and the air gap between them, towards the side where the motor 3 is located. Then, guided by the baffle, the air spreads outwards along the plane of the baffle. The faster the conductor rotor 4 rotates, the faster the airflow and the higher the heat dissipation efficiency. Multiple heat sinks 66 are provided, and all heat sinks 66 are distributed in a ring on the side wall of the conductor rotor 4. The heat sinks 66 are connected to the side wall of the conductor rotor 4 by screws. Multiple heat dissipation fins 68 are protruding on the heat sinks 66. The heat dissipation fins 68 can increase the contact area with the outside world, thereby improving the heat exchange efficiency and thus improving the heat dissipation efficiency.

[0074] The heat sink 66 is made of aluminum. Aluminum has a low density, which can reduce the weight of the heat sink 66. At the same time, since the inner wall of the conductor rotor 4 is fitted with a copper ring, the aluminum heat sink 66 can also avoid interfering with the copper ring in the conductor rotor 4 and affecting the conversion efficiency of the permanent magnet speed controller.

[0075] The protective frame 67 covers the outside of the permanent magnet speed controller from top to bottom to prevent external objects from affecting the conductor rotor 4 or the permanent magnet rotor 5 and preventing them from rotating normally.

[0076] The protective frame 67 is also fixed to the cement base with expansion bolts, and the internal space of the protective frame 67 is sufficient. When the motor 3 moves and adjusts through the base 1, it will drive the conductor rotor 4 to move together. The protective frame 67 will not affect the movement of the conductor rotor 4.

[0077] The above embodiments are merely illustrative of the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made to the technical solution based on the technical concept proposed in this invention shall fall within the scope of protection of this invention.
