Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, specifically to a self-regulating magnetic power generation device. Background Technology

[0002] Magnetic drive is a technology that uses the principle of magnetic force to achieve power transmission or object propulsion. It mainly works based on the interaction between magnetic fields and magnetic materials. When two magnetic fields exist, like magnetic poles repel each other and unlike magnetic poles attract each other. By reasonably setting the layout of the magnetic poles and the strength of the magnetic field, this magnetic force can be transformed into a force that propels the object to move, thereby achieving the driving effect.

[0003] For example, invention patent CN119362847A discloses a novel magnetic drive device. This invention uses an external motor to drive a flywheel to one side, causing a reduction gearbox and a first transmission component to rotate a counter-current crystal magnetic plate to one side. One half of the counter-current crystal magnetic plate is magnetic, and the other half is also magnetic. When the counter-current crystal magnetic plate rotates to one side, the magnetic half rotates between the first and second magnets in the first group, causing them to attract each other, while the first and second magnets in the other group repel each other. This causes two pistons to move inside the cylinder, and the second transmission component then drives a generator to generate electricity. This allows the motor to only supply power to the first transmission component for half a revolution. The first half-circle of the generator relies on the repulsive and attractive forces between two sets of first and second magnets to rotate the crankshaft, thereby reducing energy consumption and increasing the generator's power output. However, in the aforementioned comparative document, the "half-circle magnetism" of the counter-current crystal magnetic plate relies on a fixed magnet layout to provide auxiliary power. The starting torque is determined solely by the coupling between the motor and the initial magnetic force, and cannot be dynamically adjusted for different loads. Furthermore, in this comparative document, the transmission chain of motor → flywheel → gearbox → magnetic plate is a rigid connection. When the repulsive force of the magnets suddenly increases or disappears, it can cause the speed of the magnetic drive and mechanical transmission to become asynchronous, easily resulting in gear meshing impact and shortening the equipment's lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide a self-regulating magnetic power generation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a self-adjusting magnetic power generation device, comprising a housing and an adaptive drive assembly. The adaptive drive assembly is installed at the top of the housing. The adaptive drive assembly includes a bracket fixedly installed on the inner wall of one side of the housing. A commutator is installed in the inner recess of the bracket, and electromagnets are fixed in a concentric array on the outer side of the bracket. The commutator is electrically connected to the electromagnets via a cable. A frustum conical wheel is provided on the side of the bracket, and the frustum conical wheel is rotatably installed on the inner wall of the other side of the housing via a radial bearing. Permanent magnets are fixed in a concentric array on the large-diameter end face of the frustum conical wheel, and a driven gear is axially and coaxially fixed in the middle of the frustum conical wheel.

[0006] Furthermore, there is an air gap between the large-diameter end face of the frustum-shaped conical wheel and the electromagnet, and several Hall sensors are distributed along the circumference on the outer side of the end face of the frustum-shaped conical wheel and are evenly distributed on the rotation trajectory of the permanent magnet.

[0007] Furthermore, the commutator is used to switch the direction of the current in the electromagnet to achieve polarity switching, and under the action of the commutator, the magnetic poles of the electromagnet and the permanent magnet at the end of the frustum-shaped conical wheel are always opposite to each other to ensure that the direction of the magnetic force is consistent with the rotation direction of the frustum-shaped conical wheel.

[0008] Furthermore, a stepless adjustment assembly is installed at the bottom of the box. The stepless adjustment assembly includes an adjustment motor fixedly installed outside the box. A lead screw is fixedly connected to the rotating end of the adjustment motor, and a threaded sleeve is threadedly connected to the outside of the lead screw.

[0009] Furthermore, the stepless adjustment assembly also includes a connecting arm fixedly connected to the side of the threaded sleeve. A gear is rotatably installed in the recess at the end of the connecting arm, and the keyway in the gear's central hole meshes with the key protrusion on the outer circle of the key shaft. The gear can slide along the axis of the key shaft and maintain a rotational transmission connection with the key shaft. A flange is fixed at the bottom end of the connecting arm, and a micro oil pump is fixedly installed at the side end of the connecting arm. A follower nozzle is connected to the oil outlet of the micro oil pump. One end of the follower nozzle corresponds to the meshing point between the outer circle teeth of the gear and the outer conical surface teeth of the frustum conical wheel, and the other end of the follower nozzle corresponds to the meshing point between the keyway in the gear's central hole and the key protrusion on the outer circle of the key shaft. An oil storage tank is fixed to the outside of the micro oil pump, and the oil return port of the oil storage tank is connected to the inner cavity of the flange through a recovery oil pipe.

[0010] Furthermore, the outer cylindrical teeth of the gear mesh with the outer conical surface teeth of the frustum conical wheel, and the axis of the frustum conical wheel itself is inclined at an acute angle to the axis of the key shaft, and the generatrix direction of the outer conical surface of the frustum conical wheel is parallel to the axis of the key shaft.

[0011] Furthermore, the stepless adjustment assembly also includes a driven pulley coaxially connected to one end of the key shaft, a coupling connected to the other end of the key shaft, and the other end of the key shaft is connected to the differential via the coupling. A drive rack is connected to the top of the differential, and the drive rack meshes with the driven rack. A drive pulley is connected to the input end of the differential.

[0012] Furthermore, the box is fixedly installed on the workbench, and the workbench is equipped with support legs around its bottom.

[0013] Furthermore, a generator is bolted to one side of the workbench, and the generator rotor is connected to the driven pulley for rotational transmission via a transmission component.

[0014] Furthermore, a drive motor is bolted to the other side of the workbench, and the rotating end of the drive motor is connected to the drive pulley for rotational transmission through the transmission component two.

[0015] This invention provides a self-regulating magnetic power generation device, which has the following beneficial effects; 1. In use, under the action of the commutator, the magnetic poles of the electromagnet and the permanent magnet at the end of the frustum-shaped conical wheel are always opposite each other, ensuring that the direction of the magnetic force is consistent with the rotation direction of the frustum-shaped conical wheel. This makes the frustum-shaped conical wheel more continuously powered and more energy efficient under the dual drive of mechanical transmission and magnetic force acceleration, compared with the prior art which only relies on half a turn of magnetic force.

[0016] 2. In use, this application achieves stepless continuous adjustment of speed through the cooperation of a sliding gear and an inclined frustum conical wheel, and the sliding change of the gear's axial position on the key shaft. The transmission ratio can smoothly transition from a large transmission ratio at the small diameter end to a small transmission ratio at the large diameter end, adapting to load changes from high torque and low speed to low torque and high speed without stopping the machine. This allows the gear to mesh with the frustum conical wheel at its smallest diameter during the device startup phase to obtain high torque and low speed, thereby improving startup reliability. Once the speed stabilizes, the gear moves and gradually meshes with the large diameter of the frustum conical wheel to obtain low torque and high speed, thereby improving the power generation efficiency of the generator connected to the key shaft. At the same time, the conical tooth meshing between the gear and the frustum conical wheel is a line contact, which results in less wear than the rigid transmission with point contact of the crankshaft piston in existing technologies, thus extending the equipment life.

[0017] 3. In use, this application ensures precise oil supply at any transmission ratio position by making the follower nozzle move synchronously with the gear. This solves the problem of lubrication failure when the traditional fixed lubrication point is continuously adjusted. During use, the follower nozzle can accurately and continuously supply oil to the meshing point of the gear and the frustum cone wheel, as well as the sliding contact point of the gear and the key shaft, forming an oil film lubrication. This reduces the mechanical friction coefficient and reduces energy loss caused by friction, allowing more power to be transmitted to the generator and directly improving power generation efficiency. Furthermore, the closed-loop lubrication system composed of the oil reservoir and the recovery oil pipe can effectively improve the reuse rate of lubricating oil and reduce the frequency of periodic oiling. At the same time, the flange can collect splashed oil, preventing oil stains from accumulating inside the housing and reducing the workload of cleaning and maintenance. Attached Figure Description

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0021] Please see Figures 1 to 5This invention provides a technical solution: a self-adjusting magnetic power generation device, including a housing 1 and an adaptive drive assembly 2. The adaptive drive assembly 2 is installed at the top of the interior of the housing 1. The adaptive drive assembly 2 includes a bracket 201 fixedly installed on the inner wall of one side of the housing 1. A commutator 202 is installed in the inner recess of the bracket 201, and electromagnets 203 are fixedly arranged in a concentric array on the outer side of the bracket 201. The commutator 202 is electrically connected to the electromagnets 203 through a cable. A frustum conical wheel 204 is provided on the side of the bracket 201, and the frustum conical wheel 204 is rotatably installed on the inner wall of the other side of the housing 1 through a radial bearing. 04. A permanent magnet 205 is fixed in a concentric array on the large-diameter end face, and a driven rack 206 is axially and coaxially fixed in the middle of the frustum conical wheel 204. There is an air gap between the large-diameter end face of the frustum conical wheel 204 and the electromagnet 203. Several Hall sensors are distributed along the circumference on the outer side of the end face of the frustum conical wheel 204 and are evenly distributed on the rotation trajectory of the permanent magnet 205. The commutator 202 is used to switch the direction of the current in the electromagnet 203 to achieve polarity switching. Under the action of the commutator 202, the magnetic poles of the electromagnet 203 and the permanent magnet 205 at the end of the frustum conical wheel 204 are always opposite to each other to ensure that the direction of the magnetic force is consistent with the rotation direction of the frustum conical wheel 204. The specific operation is as follows: the drive motor 8 is connected to the drive pulley 311 at the input end of the differential 309 via the transmission component 2 9. The differential 309 rotates to the key shaft 306 via the side coupling 308, thereby causing the driven pulley 307 at the end of the key shaft 306 to drive the rotor of the generator 6 to rotate and generate electricity via the transmission component 1 7. On the other hand, the differential 309 drives the frustum conical wheel 204 at the top of the housing 1 to rotate through the meshing of the top drive rack 310 and the driven rack 206. The large-diameter end faces of the frustum conical wheel 204 are concentrically arrayed. A permanent magnet 205 is fixed, and an electromagnet 203 is isolated on the side of the permanent magnet 205 through an air gap. The commutator 202 is used to switch the direction of the current in the electromagnet 203 to achieve polarity switching. Under the action of the commutator 202, the magnetic poles of the electromagnet 203 and the permanent magnet 205 at the end of the frustum conical wheel 204 are always opposite to each other, ensuring that the direction of the magnetic force is consistent with the rotation direction of the frustum conical wheel 204. This makes the frustum conical wheel 204 more continuously powered and more energy efficient under the dual drive of mechanical transmission and magnetic force acceleration, compared with the existing technology that only relies on half a turn of magnetic force assistance. Please see Figures 3 to 7A stepless adjustment assembly 3 is installed at the bottom of the inner side of the housing 1. The stepless adjustment assembly 3 includes an adjustment motor 301 fixedly installed outside the housing 1. A lead screw 302 is fixedly connected to the rotating end of the adjustment motor 301, and a threaded sleeve 303 is threadedly connected to the outside of the lead screw 302. The stepless adjustment assembly 3 also includes a connecting arm 304 fixedly connected to the side of the threaded sleeve 303. A gear 305 is rotatably installed in the notch at the end of the connecting arm 304. The keyway in the middle of the gear 305 meshes with the key protrusion on the outer circle of the key shaft 306, and the gear 305 can slide along the axis of the key shaft 306 and maintain its position. The rotary transmission connection with the key shaft 306 is provided. A flange 3041 is fixed at the bottom end of the connecting arm 304, and a micro oil pump 3042 is fixedly installed on the side end of the connecting arm 304. A follower nozzle 3043 is connected to the oil outlet of the micro oil pump 3042. One end of the follower nozzle 3043 corresponds to the meshing point between the outer circular teeth of the gear 305 and the outer conical surface teeth of the frustum conical wheel 204, and the other end of the follower nozzle 3043 corresponds to the meshing point between the keyway in the middle hole of the gear 305 and the outer circular key protrusion of the key shaft 306. An oil reservoir 3044 is fixed to the outside of the micro oil pump 3042, and the oil reservoir 3044 returns oil. The inlet is connected to the inner cavity of flange 3041 via oil recovery pipe 3045. The outer cylindrical teeth of gear 305 mesh with the outer conical teeth of frustum conical wheel 204. The axis of frustum conical wheel 204 is inclined at an acute angle to the axis of key shaft 306, and the generatrix of the outer conical surface of frustum conical wheel 204 is parallel to the axis of key shaft 306. The stepless adjustment assembly 3 also includes a driven pulley 307 coaxially connected to one end of key shaft 306. The other end of key shaft 306 is connected to coupling 308, and the other end of key shaft 306 is connected to differential 309 via coupling 308. The top of the differential 309 is connected to a drive rack 310, which meshes with the driven rack 206. The input end of the differential 309 is connected to a drive pulley 311. The housing 1 is fixedly installed on the workbench 4, and the bottom of the workbench 4 is equipped with support legs 5. A generator 6 is bolted to one side of the workbench 4, and the rotor of the generator 6 is rotatably connected to the driven pulley 307 through a transmission component 1 7. A drive motor 8 is bolted to the other side of the workbench 4, and the rotating end of the drive motor 8 is rotatably connected to the drive pulley 311 through a transmission component 2 9. The specific operation is as follows: In this application, the axis of the frustum-shaped conical wheel 204 is inclined at an acute angle to the axis of the key shaft 306, so that the generatrix direction of the outer conical surface of the frustum-shaped conical wheel 204 is parallel to the axis direction of the key shaft 306. Furthermore, through the meshing of the teeth of the outer conical surface of the frustum-shaped conical wheel 204 with the outer teeth of the gear 305, and the engagement of the gear 305 with the outer key protrusion of the key shaft 306 through the keyway in the central hole, and the structural design of the gear 305 being able to slide along the axis of the key shaft 306 while maintaining a rotary transmission connection with the key shaft 306, this application achieves this through the cooperation of the sliding gear 305 and the inclined frustum-shaped conical wheel 204. By adjusting the motor 301 to drive the lead screw 302 to rotate, and then connecting the lead screw 302 to the gear 305 via the side connecting arm 304 of the threaded sleeve 303, the speed is continuously and steplessly adjusted by the sliding change of the axial position of the gear 305 on the key shaft 306. The transmission ratio can smoothly transition from a large transmission ratio at the small diameter end to a small transmission ratio at the large diameter end, adapting to load changes from high torque and low speed to low torque and high speed without stopping the machine. This allows the gear 305 to mesh with the frustum conical wheel 204 at its minimum diameter during the device startup phase to achieve high torque and low speed, thereby improving startup reliability. After the rotational speed stabilizes, gear 305 moves and gradually meshes with the large-diameter frustum conical wheel 204 to obtain low torque and high speed, thereby improving the power generation efficiency of generator 6 connected to key shaft 306. Simultaneously, the conical tooth meshing between gear 305 and frustum conical wheel 204 is a line contact, resulting in less wear than the point contact rigid transmission of existing technologies such as crankshaft pistons, extending equipment life. By making the follower nozzle 3043 move synchronously with gear 305, precise oil supply is ensured at any transmission ratio position, solving the problem of lubrication failure during stepless adjustment of traditional fixed lubrication points. During use, the follower nozzle... 3043 can precisely supply oil to the meshing point of gear 305 and frustum conical wheel 204, as well as the sliding contact point of gear 305 and key shaft 306, forming an oil film lubrication, reducing the mechanical friction coefficient and reducing energy loss caused by friction, so that more power is transmitted to generator 6, directly improving power generation efficiency. In addition, the closed-loop lubrication system composed of oil reservoir 3044 and recovery oil pipe 3045 can effectively improve the reuse rate of lubricating oil and reduce the frequency of periodic oiling. At the same time, flange 3041 can collect splashed oil, preventing oil stains from accumulating inside the housing 1 and reducing the workload of cleaning and maintenance.

[0022] In summary, when using this self-regulating magnetic power generation device: First, the drive motor 8 is connected to the drive pulley 311 at the input end of the differential 309 via transmission component 2 9. The differential 309 rotates to the key shaft 306 via the side coupling 308, thereby causing the driven pulley 307 at the end of the key shaft 306 to drive the rotor of the generator 6 to rotate and generate electricity via transmission component 1 7. On the other hand, the differential 309 drives the frustum conical wheel 204 to rotate at the top of the housing 1 through the meshing of the top drive rack 310 and the driven rack 206. The large-diameter end faces of the frustum conical wheel 204 are fixed in a concentric array. There is a permanent magnet 205, and an electromagnet 203 is isolated on the side of the permanent magnet 205 through an air gap. The commutator 202 is used to switch the direction of the current in the electromagnet 203 to achieve polarity switching. Under the action of the commutator 202, the magnetic poles of the electromagnet 203 and the permanent magnet 205 at the end of the frustum conical wheel 204 are always opposite to each other, ensuring that the direction of the magnetic force is consistent with the rotation direction of the frustum conical wheel 204. Under the dual drive of mechanical transmission and magnetic force acceleration, the frustum conical wheel 204 has a more continuous power output and higher energy utilization rate than the existing technology that only relies on half a turn of magnetic force assistance. Secondly, in this application, the axis of the frustum-shaped conical wheel 204 is inclined at an acute angle to the axis of the key shaft 306, making the generatrix direction of the outer conical surface of the frustum-shaped conical wheel 204 parallel to the axis of the key shaft 306. Furthermore, through the meshing of the teeth of the outer conical surface of the frustum-shaped conical wheel 204 with the outer teeth of the gear 305, and the engagement of the gear 305 with the outer key protrusion of the key shaft 306 via the keyway in the central hole, and the structural design allowing it to slide along the axis of the key shaft 306 while maintaining a rotational transmission connection with the key shaft 306, this application, through the cooperation of the sliding gear 305 and the inclined frustum-shaped conical wheel 204, drives the lead screw 302 to rotate via the adjusting motor 301. This, in turn, connects the lead screw 302 to the gear 305 via the connecting arm 304 on the side of the threaded sleeve 303, and the gear 305 is positioned on the key shaft 306. The sliding change of the axial position on 06 enables stepless continuous adjustment of the speed. The transmission ratio can smoothly transition from a large transmission ratio at the small diameter end to a small transmission ratio at the large diameter end. It can adapt to load changes from high torque and low speed to low torque and high speed without stopping the machine. During the device startup phase, the gear 305 meshes with the frustum conical wheel 204 at its minimum diameter to obtain high torque and low speed, thereby improving startup reliability. After the speed stabilizes, the gear 305 moves and gradually meshes with the large diameter of the frustum conical wheel 204 to obtain low torque and high speed, thereby improving the power generation efficiency of the generator 6 connected to the key shaft 306. At the same time, the conical tooth meshing between the gear 305 and the frustum conical wheel 204 is a line contact, which has less wear than the rigid transmission with point contact of the crankshaft piston in the prior art, and extends the equipment life. Finally, by making the follower nozzle 3043 move synchronously with the gear 305, precise oil supply is ensured at any transmission ratio position, solving the problem of lubrication failure of traditional fixed lubrication points during stepless adjustment. In use, the follower nozzle 3043 can precisely supply oil to the meshing point of the gear 305 and the frustum cone wheel 204, as well as the sliding contact point of the gear 305 and the key shaft 306, forming an oil film lubrication, reducing the mechanical friction coefficient and reducing energy loss caused by friction, allowing more power to be transmitted to the generator 6, directly improving the power generation efficiency. In addition, the closed-loop lubrication system composed of the oil reservoir 3044 and the recovery oil pipe 3045 can effectively improve the reuse rate of lubricating oil and reduce the frequency of periodic oiling. At the same time, the flange 3041 can collect splashed oil, avoiding the accumulation of oil stains inside the housing 1 and reducing the workload of cleaning and maintenance.
