[0073] The reduction motor 102 is fixedly arranged on the hinged plate. The reduction motor 102 rotates with the hinged plate relative to the base 900. The reduction motor 102 comprises an input end and an actuating end. The input end of the reduction motor 102 is electrically connected to a power supply. The actuating end of the reduction motor 102 is fixedly connected to the rotating part 101.

[0075] It should be noted that the screw rod and the nut are used in cooperation to reduce the pitch, so that the movement of the guide member 203 on the rotating member 101 is slow and stable, thereby improving the air gap control accuracy from the centimeter level to the millimeter level.

[0076] Reference is made to the accompanying drawings Figure 6 , Figure 7 In some embodiments, the second execution assembly 200 further includes an adjusting frame 201 and a rotating plate 202, the adjusting frame 201 is enclosed by four connecting rods and is hollow inside, the third execution assembly 300 is arranged to rotate in the adjusting frame 201, one end of the adjusting frame 201 is rotatably connected with the connecting portion of the base 900, the other end of the adjusting frame 201 is rotatably provided with the rotating plate 202, and the guide member 203 is fixedly arranged on the rotating plate 202.

[0077] In some embodiments, the guide member 203 is fixedly arranged on the rotating plate 202 and is threadedly connected with the rotating member 101; when the rotating member 101 rotates with the actuating end of the speed reducer motor 102, the guide member 203 moves linearly along the axis direction of the rotating member 101; since the one end of the rotating frame away from the rotating plate 202 is rotatably connected with the connecting portion of the base 900, when the guide member 203 drives the rotating plate 202 and the adjusting frame 201 to move, the one end of the rotating frame away from the rotating plate 202 rotates relative to the base 900, and the rotating frame tilts in the direction away from or close to the base 900, thereby driving the third execution assembly 300 arranged in the rotating frame to move in the direction away from or close to the base 900.

[0078] It should be noted that the cooperation of the first execution assembly 100 and the second execution assembly 200 is essentially to drive the third execution assembly 300 to move with the connecting portion of the rotating member 101 and the base 900 as the fulcrum, so as to achieve the purpose of reducing the speed input and increasing the output torque by changing the lever ratio.

[0079] Reference is made to the accompanying drawings Figures 8 to 12In some embodiments, the third execution assembly 300 comprises a first sliding sleeve 301, a second sliding sleeve 302, a limiting piece 303 and a guide groove 304; wherein the first sliding sleeve 301 is sleeved on the transmission shaft 1000 of the prime mover, and one end of the first sliding sleeve 301 is fixedly connected with the base 900; the second sliding sleeve 302 is slidingly sleeved on the first sliding sleeve 301, and one end away from the base 900 is fixedly provided with an extension sleeve assembly; the second sliding sleeve 302 is connected with the magnetic coupling mechanism through the extension sleeve assembly; the second sliding sleeve 302 is rotatably arranged in the rotating frame, and when the rotating frame is inclined, the second sliding sleeve 302 is driven to make linear reciprocating motion along the transmission shaft 1000.

[0080] It should be noted that the transmission shaft 1000 and the first sliding sleeve 301 are supported by bearings, one end of which is an angular contact ball bearing, and the other end of which is a cylindrical roller bearing, which is used to bear the first sliding sleeve 301 without affecting the rotation of the transmission shaft 1000.

[0081] The extension sleeve assembly is sleeved on the transmission shaft 1000, and there is a gap between the extension sleeve assembly and the transmission shaft 1000, which is designed to be suspended to ensure that the relative movement of the parts does not interfere during the adjustment of the air gap; the extension sleeve assembly comprises an extension sleeve connecting disc and an extension sleeve, the extension sleeve connecting disc is fixedly connected with one end of the second sliding sleeve 302 away from the base 900, and the extension sleeve is bearing-connected with the magnet disc assembly 500 close to the base 900; the extension sleeve connecting disc and the extension sleeve are slidingly connected, and when the second sliding sleeve 302 makes linear reciprocating motion along the transmission shaft 1000, the magnet disc assembly 500 is driven to move along the transmission shaft 1000 through the extension sleeve connecting disc and the extension sleeve.

[0083] It should be noted that the number of guide grooves 304 on the second sliding sleeve 302 corresponds to the number of limiting pieces 303 on the first sliding sleeve 301; in some embodiments, the number of guide grooves 304 and limiting pieces 303 is multiple, the more the number, the more stable the movement of the second sliding sleeve 302 relative to the first sliding sleeve 301 in the axial direction of the transmission shaft 1000, and the specific number of guide grooves 304 and limiting pieces 303 should be set according to actual conditions.

The second magnet disc assembly 500 is sleeved on the transmission shaft 1000 and located between the second eddy current disc assembly 400.

[0085] The second eddy current disc assembly 400 is connected through the connecting tile, and the magnet disc assembly 500 is connected with the telescopic sleeve through the tapered roller bearing. When the magnet connecting sleeve moves axially, the magnet disc assembly 500 is close to or away from the eddy current disc assembly 400.

[0086] It should be noted that, due to the bearing connection mode, the rotational movement of the magnet disc assembly 500 will not produce torsional force on the telescopic sleeve assembly. At the same time, the installation direction of the tapered roller bearing is the direction of the attractive force between the magnet disc assembly 500 and the eddy current disc assembly 400, which is used to resist the tendency of the magnet disc assembly 500 continuously approaching the eddy current disc assembly 400, preventing the disc rubbing failure. The second magnet disc assembly 500 is connected with the telescopic sleeve assembly through the synchronous mechanism to ensure synchronous movement, so as to ensure that the air gap values on both sides are consistent.

[0087] The limiting assembly is sleeved on the transmission shaft 1000 and abuts against the triangular frame 700 of the synchronous mechanism.

[0090] It should be noted that, in some embodiments, the tripod 700 is connected with the transmission shaft 1000 through the limiting hole in the middle part, the transmission shaft 1000 is provided with a tripod flat key on the outer wall, and the limiting hole and the tripod flat key are matched to ensure that the motor torque on the transmission shaft 1000 can be transmitted to the tripod 700; the tripod 700 is provided with three light pole 800 mounting holes at the three angles respectively, the three light poles 800 are slidably sleeved in the light pole 800 mounting holes, and the light pole 800 fixing screws are used for fixing.

[0091] The light rod 800 is arranged in the inner hole of the sliding sleeve, and the sliding sleeve is in sliding connection with the light rod 800.

[0092] In some embodiments, an input rotation speed sensor is arranged on the base 900 and used for monitoring the input rotation speed of the prime mover. A rotation speed sensing disc is arranged on the transmission shaft 1000 and used for cooperating with the input rotation speed sensor. The input rotation speed sensor outputs high and low level pulses by detecting the rotation speed sensing disc, and then the input rotation speed of the permanent magnet speed regulator is calculated. The notch on the outer circumferential surface of the rotation speed sensing disc is specially designed. The forward and reverse directions of the permanent magnet speed regulator are determined by detecting the pulse time sequence signal output by the output rotation speed sensor.

[0093] In some embodiments, an output rotation speed sensor is arranged on one side of the magnetic coupling mechanism and used for monitoring the actual rotation speed of the load equipment. The output rotation speed sensor is arranged on the sensor support. The output rotation speed sensor can output high and low level pulse signals by detecting the screw protrusions on the magnetic coupling mechanism, and then the output rotation speed is calculated.

[0094] It should be noted that the input side and the output side of the simple permanent magnet speed regulator can be interchanged according to actual needs. When the input side and the output side are interchanged, the rotation speed detected by the input rotation speed sensor is the output rotation speed.

[0095] In some embodiments, a position encoder is arranged on the second sliding sleeve 302 and used for monitoring the displacement distance of the second sliding sleeve 302. The displacement distance of the second sliding sleeve 302 is detected, and the air gap size between the two-magnet disc assembly 500 and the eddy current disc assembly 400 is determined by calculation. In some embodiments, the maximum and minimum limit values of the air gap are set to prevent the permanent magnet speed regulator from being damaged due to the too small air gap.

[0096] In some embodiments, a temperature sensor is used on one side of the magnetic coupling mechanism to monitor the working temperature of the magnetic coupling mechanism; the temperature sensor is installed on a sensor bracket, and the temperature sensor is an infrared non-contact temperature sensor, which detects the surface temperature of the magnetic coupling mechanism to output an analog electrical signal, and then determines the working temperature of the magnetic coupling mechanism; in some embodiments, when the temperature sensor detects that the working temperature of the permanent magnet speed regulator is too high, the temperature sensor sends an alarm signal through the control system, so as to control the emergency shutdown of the equipment in an automatic or manual manner.

[0097] In some embodiments, the power transmission process of the prime mover is as follows:

[0098] After the prime mover is turned on, the transmission shaft 1000 is driven to rotate, and the rotary mechanical energy is transmitted to the tripod 700 through the tripod key, further transmitted to the polished rod 800, and then transmitted to the magnet disc assembly 500 through the sliding sleeve. The magnet disc assembly 500 is coupled with the eddy disc assembly 400 through a magnetic field, and then the rotary mechanical energy is transmitted to the load equipment through the output side components.

[0099] In some embodiments, the adjustment process of the first execution assembly 100, the second execution assembly 200 and the third execution assembly 300 is as follows:

[0100] When the reduction motor 102 rotates clockwise, the rotating member 101 is rotated to drive the guide member 203 to move away from the base 900, the rotating frame is tilted away from the base 900, and the second sliding sleeve 302 is driven by the rotating frame to move away from the base 900 relative to the first sliding sleeve 301. The second sliding sleeve 302 drives a magnet disc assembly 500 to move away from the base 900 through the telescopic sleeve connecting disc and the telescopic sleeve, and then drives the second magnet disc assembly 500 to move away from the second eddy disc assembly 400 through the synchronous mechanism, so that the air gap is continuously increased, the coupling strength of the magnetic coupling mechanism is continuously reduced, the power transmission of the prime mover is reduced, and the rotating speed of the load equipment is reduced. On the contrary, when the reduction motor 102 rotates counterclockwise, the second magnet disc assembly 500 is driven to move close to the second eddy disc assembly 400 through the synchronous mechanism, so that the air gap is continuously reduced, the coupling strength of the magnetic coupling mechanism is continuously enhanced, the power transmission of the prime mover is enhanced, and the rotating speed of the load equipment is increased.

[0101] In some embodiments, the physical quantity monitoring process is as follows:

[0102] The input rotating speed sensor is used for monitoring the rotating speed of the prime mover, and providing data for internal operation of the magnetic speed regulator control system, and the output rotating speed sensor is used for monitoring the actual rotating speed of the load device, when the actual rotating speed deviates from the set data, the first executing component 100, the second executing component 200 and the third executing component 300 are coordinated to increase or decrease the air gap, so as to adjust the coupling strength of the magnetic coupling mechanism, and further adjust the actual working rotating speed of the load device.

[0103] The position sensor is used for monitoring the displacement distance of the sliding sleeve, and further calculating the air gap size between the magnet disc and the conductive disc, and in addition, a virtual limit can be set to prevent the magnet disc assembly 500 and the eddy disc assembly 400 from rubbing disc failure.

[0104] The temperature sensor is used for detecting the surface temperature of the magnetic coupling mechanism, when the temperature is too high, the temperature sensor sends an alarm signal to the device control room through the control system, and realizes automatic or manual, remote or on-site control action through internal logic, so as to realize the actions of reducing load, reducing rotating speed or even stopping.

[0105] The simple permanent magnet regulator provided by the application can improve the air gap control precision of the magnetic coupling mechanism through the cooperation of the first executing component 100, the second executing component 200 and the third executing component 300, can flexibly adjust the position of the first executing component 100 through the rotating connection between the first executing component 100 and the base 900, improve the space resource utilization rate, reduce the mechanical fatigue of the second executing component 200 and the third executing component 300 through the flexible avoidance of the first executing component 100, transmit the output kinetic energy of the prime mover to the load device and adjust the rotating speed of the load device through the cooperation of the first executing component 100, the second executing component 200, the third executing component 300, the magnetic coupling mechanism and the synchronous mechanism, reduce the volume of the adjusting mechanism by integrating the speed reducer 102 on the base 900 of the adjusting mechanism, the combined structure of the first sliding sleeve 301 and the second sliding sleeve 302 has good sealing effect, dustproof and moistureproof, and improves the operation reliability of the adjusting mechanism, the input side of the permanent magnet speed regulator uses the base 900 as support, the output side uses the shaft of the load device to provide support through bearing mode, both sides have support points, avoiding the suspended effect caused by the single side support of the permanent magnet speed regulator components, further reducing the damage of the weight of the permanent magnet speed regulator components to the shaft and bearing of the motor or load device, and the permanent magnet speed regulator can interchange the input side and the output side according to the on-site working requirements.
