Description

Technical Field

[0001] This invention relates to the field of power generation equipment technology, specifically to an energy-saving magnetic induction-assisted control mechanism for power generation equipment and its control method. Background Technology

[0002] Power generation equipment refers to devices that convert other forms of energy into electrical energy. They are widely used in industry, transportation, residential power supply, and various emergency backup power sources. In wind power generation, hydropower generation, tidal power generation, and other power generation industries, it is typically necessary to convert linear reciprocating motion or rotary motion into the input power of a generator. In existing reciprocating motion driven power generation devices, crank-connecting rod mechanisms, cam mechanisms, or linear motors are commonly used as drive components. The motor continuously outputs torque to overcome electromagnetic resistance and mechanical friction resistance during the power generation process, thereby maintaining the continuous operation of the generator.

[0003] The inventors of this application discovered in their research that the core defect of the above-mentioned prior art is that: in the driving stroke of the power generation equipment, magnetic assistance is mostly unidirectional, and magnetic force cannot be used to achieve auxiliary reset in the return phase, resulting in the load consumption of the drive motor in the return phase not being effectively reduced, and problems such as return jamming and poor motion smoothness are also likely to occur. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an energy-saving magnetic induction-assisted control mechanism and its control method for power generation equipment, solving the problem that magnetic assistance is mostly unidirectional during the drive stroke of power generation equipment, and magnetic force cannot be used to achieve auxiliary reset during the return stroke.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving magnetic induction-assisted control mechanism for power generation equipment, comprising a base and a cylinder. An electromagnet is fixedly connected to the middle of the cylinder, and a switch sensor is installed on the outer wall of the electromagnet. A power source is installed on the other side of the cylinder, and a threaded rod is fixedly connected to the output end of the power source. A moving block is threadedly connected to the outer wall of the threaded rod, and a slider is fixedly connected to the bottom of the moving block. A slide rail is slidably connected to the bottom of the slider, and the bottom of the slide rail is fixedly connected to the inner wall of the cylinder. A rotating block is rotatably connected to one side of the moving block, and a rotating shaft is installed at one end of the rotating block via a flange. A permanent magnet is fixedly connected to the outer wall of the rotating shaft, and the outer wall of the rotating shaft movably passes through the central hole of the cylinder. A pressing plate is fixedly connected to one side of the permanent magnet, and a control component for adjusting the magnetic force is installed inside the cylinder.

[0006] By adopting the above technical solution, the power source receives a controller command to operate in the forward direction, driving the threaded rod to drive the moving block to translate axially. The slider slides along the slide rail to provide stable support throughout the entire stroke. When the pressing plate moves with the permanent magnet to a preset trigger position close to the electromagnet, it triggers the switch sensor. The switch sensor sends a signal to the controller, which controls the magnetic pole state of the electromagnet according to the preset working mode: In the normally powered standby switching mode, the controller first controls the electromagnet and the permanent magnet to maintain an opposite pole attraction state, driving the permanent magnet to gradually approach the electromagnet. After the pressing plate triggers the switch sensor, a safety gap is reserved to avoid hard collisions. The controller immediately switches the magnetic poles of the electromagnet to generate a like pole repulsion force, which is superimposed on the driving force of the power source to form... The magnetic induction assists in outputting power. After the work is completed, it switches back to the attraction state to pull the permanent magnet back quickly. In the normally power-off triggered power-on mode, the electromagnet remains power-off during standby and return phases. It uses the natural magnetic attraction between its iron core and the permanent magnet to achieve zero-power attraction and reset. It is only briefly powered on after the switch sensor is triggered to generate like-pole repulsion to drive the work. After the work is completed, it is powered off again to restore the natural attraction state. Both modes achieve the effect of bidirectional magnetic induction assistance and significantly reduce the power source and load consumption during the return phase. The normally power-off triggered power-on mode consumes electrical energy only during the short interval of driving the work, further reducing the power-on time of the electromagnet and the continuous input of external electrical energy, thus achieving the effect of energy saving.

[0007] Preferably, the control component includes a mounting frame, the inner wall of which is fixedly connected to the outer wall of the cylinder. Guide rods are symmetrically fixedly connected to the inner wall of the mounting frame. A movable plate is slidably connected to the outer wall of the guide rods. A connecting rod is fixedly connected to the bottom of the movable plate. A shielding plate is fixedly connected to one end of the connecting rod. The shielding plate is disposed on the magnetic field path between the electromagnet and the permanent magnet. The shielding plate is disposed on the side closer to the electromagnet. The cylinder has symmetrically opened clearance grooves for the shielding plate to pass through. The shielding plate is made of a soft magnetic material with high magnetic permeability.

[0008] Preferably, a second power source is installed on one side of the mounting frame, and a bidirectional lead screw is fixedly connected to the output end of the second power source. One end of the bidirectional lead screw is rotatably connected to the side of the mounting frame away from the second power source. Screw holes are provided on the top of both movable plates, and the two movable plates are threaded to the two ends of the bidirectional lead screw through the screw holes.

[0009] Preferably, a limiting block is fixedly connected to one side of the guide rod, and the limiting block is used to limit the movement of the moving plate.

[0010] Preferably, a mounting base is fixedly connected to the outer wall of the movable block, a connecting shaft is rotatably connected to the interior of the mounting base, a gear is fixedly connected to the outer wall of the connecting shaft, a rack is meshed with the tooth end of the gear, the top of the rack is fixedly connected to the inner wall of the cylinder, a photoelectric encoder is installed at one end of the connecting shaft, the housing of the photoelectric encoder is fixedly connected to the mounting base, and the output shaft of the photoelectric encoder is fixedly connected to one side of the connecting shaft.

[0011] Preferably, a generator is installed at the other end of the cylinder, and the output end of the generator is fixedly connected to a main shaft, which is connected to one end of a rotating shaft via a spline connection.

[0012] Preferably, the top of the base is symmetrically fixedly connected to a support block, and the top of the support block is fixedly connected to the bottom of the cylinder.

[0013] Preferably, a controller is mounted on the top of the base, and the controller is electrically connected to the electrical components in the device.

[0014] Preferably, the electromagnet, the switch sensor, and the controller are connected in a circuit. The controller is used to receive the trigger signal from the switch sensor and to convert the magnetic poles of the electromagnet. The controller is also connected in a circuit with the photoelectric encoder and the second power source. The controller is used to receive the pulse signal from the photoelectric encoder and calculate the speed of the permanent magnet, and to control the start, stop, forward and reverse rotation of the second power source.

[0015] A control method for an energy-saving magnetic induction-assisted control mechanism of a power generation device includes the following steps: When in use, after the equipment is started, the power source one receives the controller command and runs in the forward direction, driving the threaded rod to drive the moving block to move axially, and the slider slides along the slide rail, driving the permanent magnet to gradually approach the electromagnet; In the normally powered-off triggered power-on mode, the electromagnet is powered off during standby and return strokes. The iron core, exhibiting the characteristics of an iron block, naturally attracts the permanent magnet, using zero-power magnetic attraction to pull the permanent magnet back to its reset position. When the permanent magnet moves to approximately 5mm from the electromagnet, the switch sensor is triggered, and the controller briefly powers on the electromagnet to generate a repulsive force between the same poles to perform work. After the work is completed, the power is turned off, and the natural attraction returns to normal. In the normally powered-on standby switching mode, the electromagnet remains powered on. Initially, opposite poles attract to assist in approaching the magnet. After triggering the switch sensor, the current direction is switched to generate a repulsive force between the same poles to perform work. After the work is completed, the current direction is switched back to opposite poles attracting to pull the magnet back to its reset position. The number of electromagnets and permanent magnets can be flexibly configured according to the power generation requirements, including but not limited to a single magnetic pair layout of a single set of fixed electromagnets and moving permanent magnets, a double magnetic pair layout of two sets of fixed electromagnets placed on both sides and a single permanent magnet in the middle reciprocating motion, and a multi-magnet linkage layout of multiple sets of magnets arranged in series along the axial direction. When the magnetic intensity needs to be adjusted, the controller drives the second power source to rotate the bidirectional lead screw. The two sets of moving plates move synchronously in opposite directions along the guide rod, causing the shielding plate made of high magnetic permeability material to enter or exit the magnetic field path through the clearance groove. When the moving block is displaced, the following mounting base drives the gear to roll along the rack. The photoelectric encoder converts the angular displacement into a pulse signal and transmits it to the controller. The controller analyzes and obtains the real-time movement speed of the permanent magnet. The closed-loop control shielding plate is precisely positioned, allowing the magnetic force to adapt to the real-time movement state. Ultimately, the axial power is converted into rotational motion by the rotating block, which drives the generator through the spline to generate electricity.

[0016] This invention provides an energy-saving magnetic induction-assisted control mechanism for power generation equipment and its control method. It has the following beneficial effects: 1. In this invention, a power source receives a controller command to operate in the forward direction, driving a threaded rod to move a moving block axially. A slider slides along a rail, providing stable support throughout its travel. When the pressing plate moves with the permanent magnet to a preset trigger position near the electromagnet, it triggers a switch sensor. The switch sensor sends a signal to the controller, which controls the magnetic pole state of the electromagnet according to a preset operating mode: In the normally powered standby switching mode, the controller first controls the electromagnet and permanent magnet to maintain an opposite pole attraction state, causing the permanent magnet to gradually approach the electromagnet. After the pressing plate triggers the switch sensor, a safety gap is reserved to avoid hard collisions. The controller immediately switches the electromagnet's magnetic poles to generate a like pole repulsion force, which, combined with the driving force of the power source, forms a magnetic field. The electromagnet assists in outputting power, and after completing its work, it switches back to the attraction state to pull the permanent magnet back quickly. In the normally power-off triggered power-on mode, the electromagnet remains power-off during standby and return phases, using the natural magnetic attraction between its iron core and the permanent magnet to achieve zero-power attraction and reset. It is only briefly powered on after the switch sensor is triggered to generate a like-pole repulsive force to drive the work. After the work is completed, it is powered off again to restore the natural attraction state. Both modes achieve bidirectional magnetic assistance and significantly reduce the power source and load consumption during the return phase. The normally power-off triggered power-on mode consumes electrical energy only during the brief interval of driving the work, further reducing the power-on time of the electromagnet and the continuous input of external electrical energy, thus achieving the effect of energy saving.

[0017] 2. In this invention, the controller issues a command to start the second power source, which drives the bidirectional lead screw to rotate synchronously. The two moving plates are engaged with the two reverse threads of the bidirectional lead screw through the top screw hole. Under the constraint of the guide rod, they can slide synchronously towards or away from each other. The displacement of the moving plates is transmitted to the shielding plate through the connecting rod, allowing the shielding plate to move precisely into or out of the magnetic field path between the electromagnet and the permanent magnet through the avoidance groove on the cylinder. The shielding plate, made of high permeability soft magnetic material, can bypass and shunt the magnetic lines of force to attenuate the effective magnetic flux, so as to achieve non-contact magnetic field control without adjusting the electromagnet current, thereby reducing the heat generation and energy consumption of the electromagnet.

[0018] 3. In this invention, when the moving block is driven or magnetically assisted to generate axial displacement, it drives the mounting base to move synchronously, causing the internal gears to mesh and roll along the rack. The rotation of the gears is transmitted to the output shaft of the photoelectric encoder via the connecting shaft. The photoelectric encoder fixed on the mounting base converts the angular displacement into a pulse signal and transmits it to the controller in real time. The controller analyzes the pulse frequency to obtain the real-time movement speed of the permanent magnet, and then controls the start, stop, forward and reverse rotation of the second power source according to the preset strategy, so as to drive the shielding plate to accurately reach the target blocking position. This realizes the dynamic adaptive adjustment of the magnetic force intensity following the movement state of the permanent magnet, ensuring the smoothness and control accuracy of the magnetic assistance process, and further reducing the overall ineffective energy consumption of the system.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 -Appendix Figure 9 This invention provides an energy-saving magnetic induction-assisted control mechanism for power generation equipment, including a base 1 and a cylindrical body 2. An electromagnet 201 is fixedly connected to the middle of the cylindrical body 2, and a switch sensor 202 is installed on the outer wall of the electromagnet 201. A power source 203 is installed on the other side of the cylindrical body 2, and a threaded rod 204 is fixedly connected to the output end of the power source 203. A movable block 205 is threadedly connected to the outer wall of the threaded rod 204, and a slider 206 is fixedly connected to the bottom of the movable block 205. A slide rail 207 is dynamically connected, and the bottom of the slide rail 207 is fixedly connected to the inner wall of the cylinder 2. A rotating block 208 is rotatably connected to one side of the moving block 205. A rotating shaft 210 is installed at one end of the rotating block 208 through a flange 209. A permanent magnet 211 is fixedly connected to the outer wall of the rotating shaft 210. The outer wall of the rotating shaft 210 moves through the central hole of the cylinder 2. A pressing plate 212 is fixedly connected to one side of the permanent magnet 211. An adjustment component for adjusting the magnetic strength is installed inside the cylinder 2.

[0023] Specifically, after the equipment is started, the power source 203 receives the operating command from the controller 9 and begins to operate in the forward direction, driving the threaded rod 204 to rotate synchronously. During the rotation of the threaded rod 204, it drives the moving block 205 connected to the outer wall thread to translate axially. The slider 206 fixed at the bottom of the moving block 205 slides linearly along the guide path of the slide rail 207. The slide rail 207 provides stable support for the full stroke movement of the moving block 205. The controller 9 first controls the electromagnet 201 to maintain the opposite polarity attraction state with the adjacent end faces of the permanent magnet 211. During the translation of the moving block 205, it drives the rotating block 208 connected to one side to move synchronously. The rotating block 208 moves along the central hole of the cylinder 2 towards the electromagnet 201 through the rotating shaft 210 connected to the flange 209, so that the permanent magnet 211 gradually approaches the electromagnet 201. When the pressing plate 212 contacts the electromagnet 201... When the trigger end face of the switch sensor 202 is activated, a certain safety gap is reserved between the permanent magnet 211 and the electromagnet 201 to avoid direct rigid collision between the permanent magnet 211 and the electromagnet 201. The switch sensor 202 transmits a trigger signal to the controller 9. The controller 9 immediately controls the electromagnet 201 to switch its current magnetic pole, or makes the electromagnet 201 magnetized, so that the end face of the electromagnet 201 generates a magnetic field with the same polarity as the adjacent end face of the permanent magnet 211. The instantaneous repulsive force generated by the same polarity magnetic field will push the permanent magnet 211 to move rapidly in the opposite direction. This part of the magnetic repulsive force will be superimposed on the driving force of the power source 203, and together drive the rotating shaft 210 to output power away from the electromagnet 201. After the permanent magnet 211 completes the outward work stroke, the controller 9 switches the magnetic pole of the electromagnet 201 back to the attractive state with opposite polarity to the permanent magnet 211. The controller 9 controls the magnetic poles of the electromagnet 201 in two modes: a normally powered standby switching mode and a normally powered off triggered power-on mode. The controller 9 controls the magnetic pole state of the electromagnet 201 according to the preset working mode. In the normally de-energized triggered energization mode, the electromagnet 201 remains de-energized until the switch sensor 202 is triggered. At this time, the iron core end face of the electromagnet 201 exhibits the characteristics of an iron block, naturally forming a magnetic attraction force with the adjacent end face of the permanent magnet 211, which attracts the permanent magnet 211 with opposite polarities. This allows the permanent magnet 211 to be pulled closer to the electromagnet 201 by the magnetic attraction force in the initial stage. When the pressing plate 212 moves with the permanent magnet 211 to a position about 5mm away from the end face of the electromagnet 201, the switch sensor 202 is triggered. After receiving the trigger signal, the controller 9 immediately controls the electromagnet 201 to be energized, and its end face generates the same polarity as the adjacent end face of the permanent magnet 211. The magnetic field of the electromagnet 201 utilizes the repulsive force generated by the like poles when the current is applied to drive the permanent magnet 211 to move rapidly in the opposite direction to do work. After the work stroke ends, the controller 9 cuts off the power supply to the electromagnet 201, and the end face of the electromagnet 201 returns to the characteristics of an iron block, forming a natural attraction state again, pulling the permanent magnet 211 back to its reset state. In this mode, the electromagnet 201 is only powered on and consumes energy during the short interval of driving and doing work, while it is in a de-powered state during the standby and return stroke phases, which account for a large proportion of the entire operating cycle. This significantly reduces the continuous power-on time of the electromagnet 201, reducing the power consumption of the electromagnet 201 from the source, and the energy-saving effect is particularly significant. In the constant-power standby switching mode, the electromagnet 201 remains energized during equipment operation. Initially, the adjacent end faces of the electromagnet 201 and the permanent magnet 211 are attracted to each other with opposite polarities. When the switch sensor 202 is triggered, the controller 9 immediately controls the electromagnet 201 to switch the current direction, causing its end face to generate a magnetic field with the same polarity as the adjacent end face of the permanent magnet 211. This generates a repulsive force that pushes the permanent magnet 211 to move in the opposite direction to do work. After the work stroke ends, the controller 9 switches the current direction again, restoring the opposite polarity attraction state and pulling the permanent magnet 211 back to reset. In this mode, the power source 203 only needs to provide a small power input for initial startup and stroke maintenance. The output is superimposed by magnetic repulsion during the work stroke, and the reset is assisted by magnetic attraction during the return stroke. Both strokes are assisted by magnetic force, effectively sharing the continuous load of the power source 203 and reducing power consumption. It should be noted that the number of electromagnets 201 and permanent magnets 211 can be flexibly configured according to the power generation requirements, including but not limited to a single magnetic pair layout of a single set of fixed electromagnets 201 and moving permanent magnets 211, a double magnetic pair layout of two sets of fixed electromagnets 201 placed on both sides and cooperating with a single permanent magnet 211 in the middle for reciprocating motion, and a multi-magnet linkage layout of multiple sets of magnets arranged in series along the axial direction.

[0024] Please see the appendix Figure 3 Appendix Figure 4 Appendix Figure 7 -Appendix Figure 9The control component includes a mounting frame 3, the inner wall of which is fixedly connected to the outer wall of the cylinder 2. A guide rod 301 is symmetrically fixedly connected to the inner wall of the mounting frame 3. A movable plate 302 is slidably connected to the outer wall of the guide rod 301. A connecting rod 303 is fixedly connected to the bottom of the movable plate 302. A shielding plate 304 is fixedly connected to one end of the connecting rod 303. The shielding plate 304 is set on the magnetic field path between the electromagnet 201 and the permanent magnet 211. The shielding plate 304 is set on the side close to the electromagnet 201. The cylinder 2 has symmetrically opened clearance grooves 305 for the shielding plate 304 to pass through. The shielding plate 304 is made of a soft magnetic material with high magnetic permeability. A second power source 4 is installed on one side of the mounting frame 3. A bidirectional lead screw 401 is fixedly connected to the output end of the second power source 4. One end of the bidirectional lead screw 401 is rotatably connected to the side of the mounting frame 3 away from where the second power source 4 is installed. The top of the two movable plates 302 are provided with screw holes. The two movable plates 302 are threadedly connected to the two ends of the bidirectional lead screw 401 through the screw holes. A limiting block 5 is fixedly connected to one side of the guide rod 301. The limiting block 5 is used to limit the movement of the moving plate 302.

[0025] Specifically, when it is necessary to adjust the magnetic strength between the electromagnet 201 and the permanent magnet 211, the controller 9 controls the power source 4 to start, driving the bidirectional lead screw 401 to rotate. The two moving plates 302, through the screw holes at their tops, respectively engage with the two reverse threads of the bidirectional lead screw 401, achieving synchronous sliding towards or away from each other under the constraint of the guide rod 301. The displacement of the moving plates 302 is transmitted to the shielding plate 304 through the connecting rod 303, allowing the shielding plate 304 to accurately move into or out of the magnetic field path between the electromagnet 201 and the permanent magnet 211 via the clearance groove 305 opened on the cylinder 2. Made of high-permeability soft magnetic material, when the shielding plate 304 is located on one side of the electromagnet 201 and inserted into the magnetic field gap, it provides a low magnetic reluctance path, bypassing or shielding the magnetic lines of force that originally passed through the permanent magnet 211, thereby attenuating the effective magnetic flux and reducing the magnetic force. When the shielding plate 304 is removed, the magnetic force is restored. By controlling the insertion depth of the shielding plate 304, non-contact current shunting control of the magnetic field can be achieved without changing the current of the electromagnet 201, reducing heat generation and energy consumption, and realizing energy-saving control of the magnetic force adjustment link. The power source 1 203 and the power source 2 4 include, but are not limited to, servo motors.

[0026] Please see the appendix Figure 1 -Appendix Figure 6A mounting base 6 is fixedly connected to the outer wall of the movable block 205. A connecting shaft 601 is rotatably connected inside the mounting base 6. A gear 602 is fixedly connected to the outer wall of the connecting shaft 601. A rack 603 is meshed with the tooth end of the gear 602. The top of the rack 603 is fixedly connected to the inner wall of the cylinder 2. A photoelectric encoder 604 is installed at one end of the connecting shaft 601. The housing of the photoelectric encoder 604 is fixedly connected to the mounting base 6. The output shaft of the photoelectric encoder 604 is fixedly connected to one side of the connecting shaft 601. A controller 9 is mounted on the top of the base 1, and the controller 9 is electrically connected to the electrical components in the equipment; The electromagnet 201, the switch sensor 202, and the controller 9 are connected by a circuit. The controller 9 is used to receive the trigger signal from the switch sensor 202 and to convert the magnetic poles of the electromagnet 201. The controller 9 is also connected by a circuit to the photoelectric encoder 604 and the second power source 4. The controller 9 is used to receive the pulse signal from the photoelectric encoder 604 and to calculate the movement speed of the permanent magnet 211. This is used to control the start, stop, forward and reverse rotation of the second power source 4.

[0027] Specifically, when the moving block 205 is driven by the power source 203 or undergoes axial displacement due to magnetic assistance, the mounting base 6 moves accordingly, causing the internally rotating gear 602 to roll along the rack 603. The rotation of the gear 602 is transmitted to the output shaft of the photoelectric encoder 604 through the connecting shaft 601. The housing of the photoelectric encoder 604 is fixed by the mounting base 6, and its internal components convert the angular displacement of the output shaft into pulse signals, which are output to the controller 9 in real time. The controller 9 accurately calculates the real-time movement speed of the permanent magnet 211 by analyzing the pulse frequency. The controller 9 receives the speed feedback signal from the photoelectric encoder 604 and, according to the preset control strategy, controls the start / stop and forward / reverse rotation of the power source 4, driving the bidirectional wire. Rod 401 drives two sets of moving plates 302 to move synchronously, ultimately pushing the shielding plate 304 precisely to the preset target shielding position. It dynamically adjusts the effective magnetic field area between the electromagnet 201 and the permanent magnet 211, driving the shielding plate 304 to move precisely to the target position. This dynamically adjusts the strength of the magnetic force between the electromagnet 201 and the permanent magnet 211, matching it with the actual movement state of the permanent magnet 211. This ensures that the adjustment of the magnetic force intensity can accurately follow the movement state of the permanent magnet 211, avoiding energy waste caused by excessive magnetic force or insufficient assistance caused by insufficient magnetic force, requiring additional power compensation from the power source 203. This ensures the smoothness of the assistance process and the accuracy of the control, further reducing the overall ineffective energy consumption of the system.

[0028] Please see the appendix Figure 1 -Appendix Figure 3 A generator 7 is installed at the other end of the cylinder 2. The output end of the generator 7 is fixedly connected to a main shaft, which is connected to one end of the rotating shaft 210 via a spline fit.

[0029] Specifically, under the axial magnetic assistance, the permanent magnet 211 drives the rotating shaft 210 to synchronously complete the axial reciprocating push-pull motion. This axial power is converted into rotational motion through the transmission structure inside the rotating block 208. One end of the rotating shaft 210 is connected to the main shaft of the generator 7 through a spline fit. This spline fit allows the rotating shaft 210 to seamlessly transmit rotational torque to the main shaft of the generator 7 while the moving block 205 moves axially. When the main shaft of the generator 7 is continuously driven to rotate, the internal rotor cuts the magnetic field lines to efficiently convert the input rotational mechanical kinetic energy into electrical energy output. The spline fit structure can simultaneously accommodate axial sliding and circumferential torque transmission, realizing energy recovery or auxiliary power supply, and improving the energy utilization efficiency of the entire system.

[0030] Please see the appendix Figure 1 Appendix Figure 2 The top of the base 1 is symmetrically and fixedly connected to a support block 8, and the top of the support block 8 is fixedly connected to the bottom of the cylinder 2.

[0031] Specifically, the symmetrically arranged support blocks 8 form a stable bottom bearing frame, which can directly transmit the high-frequency vibration generated during the operation of the cylinder 2 to the base 1, thereby enhancing the installation rigidity and vibration resistance of the cylinder 2 and preventing radial displacement of the cylinder 2.

[0032] A control method for an energy-saving magnetic induction-assisted control mechanism of a power generation device includes the following steps: When in use, after the equipment is started, the power source 203 receives the command from the controller 9 and runs in the forward direction, driving the threaded rod 204 to drive the moving block 205 to move axially, and the slider 206 slides along the slide rail 207, driving the permanent magnet 211 to gradually approach the electromagnet 201. In the normally powered-off triggered power-on mode, the electromagnet 201 is powered off during standby and return strokes. The iron core exhibits the characteristics of an iron block and naturally attracts the permanent magnet 211. The permanent magnet 211 is pulled back to its reset position with zero-power magnetic attraction. When the permanent magnet 211 moves to a distance of about 5mm from the electromagnet 201, the switch sensor 202 is triggered. The controller 9 controls the electromagnet 201 to be briefly powered on to generate a like-pole repulsive force to push and do work. After the work is done, the power is turned off and the natural attraction is restored. In the normally powered-on standby switching mode, the electromagnet 201 is always powered on. Initially, the opposite poles attract to assist in approaching. After the switch sensor 202 is triggered, the current direction is switched to generate a like-pole repulsive force to do work. After the work is done, the current direction is switched back to opposite pole attraction to pull the return stroke. The number of electromagnets 201 and permanent magnets 211 can be flexibly configured according to the power generation requirements, including but not limited to a single magnetic pair layout of a single set of fixed electromagnets 201 and moving permanent magnets 211, a double magnetic pair layout of two sets of fixed electromagnets 201 placed on both sides and cooperating with a single permanent magnet 211 in the middle to reciprocate, and a multi-magnet linkage layout of multiple sets of magnets arranged in series along the axial direction. When the magnetic force intensity needs to be adjusted, the controller 9 drives the power source 2 4 to rotate the bidirectional lead screw 401. The two sets of moving plates 302 move synchronously in opposite directions along the guide rod 301, driving the shielding plate 304 made of high magnetic permeability material to enter or exit the magnetic field path through the clearance groove 305. When the moving block 205 moves, the following mounting base 6 drives the gear 602 to roll along the rack 603. The photoelectric encoder 604 converts the angular displacement into a pulse signal and transmits it to the controller 9. The real-time movement speed of the permanent magnet 211 is obtained by analysis. The closed-loop control shielding plate 304 is precisely positioned so that the magnetic force is adapted to the real-time movement state. Ultimately, the axial power is converted into rotational motion by the rotating block 208, which drives the generator 7 through the spline to generate electricity.
