[0016] Technical effects and advantages of the present invention:

[0017] 1. The present invention supports a workbench by arranging a load-bearing column and a working column. The workbench is used to install a solar panel. When sunlight irradiates on a photoreceptor, the sunlight will be projected on the surface of the photoreceptor due to the shielding of the shading column. The projection causes the resistance value of some photoresistors to change. The first processor is used to process the resistance value change of the photoresistor to obtain the solar position data. The solar position data is subsequently input into the second processor, and the second processor is used to control the input working current of the electromagnet disk, and then the repulsive force of the same-polar magnetism is used to promote the movement of the lifting column rod. By controlling the lifting state of the lifting column rods inside the four working columns, the inclination of the workbench is realized, and the corresponding direction of the workbench is adjusted to face the sunlight, thereby improving the solar power generation efficiency compared with the existing solar panels that cannot be adjusted.

[0018] 2. The present invention sets a fixed block. When the height of the lifting column rod is adjusted, the second processor is used to control the input current of the electromagnet block. The opposite magnetic poles of the electromagnet block and the permanent magnet block are attracted to each other, and the clamping strip contracts to move inside the fixed block, so that the clamping strip is released from the clamping slot on the lifting column rod, which is convenient for lifting and lowering adjustment of the lifting column rod. After the electromagnet block is powered off, the magnetism of the electromagnet block is eliminated, and the reset spring is used to push the clamping strip to reset. The clamping strip is re-clamped into the clamping slot on the lifting column rod, which is convenient for fixing the lifting column rod, and further convenient for cutting off the input current to the electromagnet disk, thereby saving unnecessary waste of electric energy and improving the stability of the workbench after the direction is adjusted.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides Figure 1-8 The magnetic shadow intelligent light tracking system shown in the figure comprises a workbench 1, a load-bearing column 2 is arranged at the center of the bottom of the workbench 1, and working columns 3 are arranged at the four sides of the bottom of the workbench 1;

[0030] The bottom end of the load-bearing column 2 is fixedly provided with a base 4, the top of the load-bearing column 2 is fixedly provided with a load-bearing column head 5, the inside of the working column 3 is hollow, a lifting column rod 6 is movably provided inside the working column 3, a working column head 7 is fixedly provided on the top of the lifting column rod 6, a load-bearing groove 8 is fixedly provided at the center of the bottom end surface of the workbench 1, and working grooves 9 are fixedly provided on the four sides of the bottom end surface of the workbench 1, the load-bearing column head 5 is movably connected to the load-bearing groove 8, and the working column head 7 is movably connected to the working groove 9;

[0031] An electromagnet disk 10 is fixedly provided at the bottom of the working column 3, a permanent magnet disk 11 is fixedly provided at the bottom end of the lifting column rod 6, the electromagnet disk 10 and the permanent magnet disk 11 are matched, and slots 12 are fixedly provided on both sides of the surface of the lifting column rod 6, and fixed blocks 13 are fixedly provided on both sides of the top of the working column 3, and a clamping strip 14 is movably provided inside the fixed block 13, and the clamping strip 14 is clamped with the clamping slot 12, and an electromagnet block 15 is fixedly provided inside the fixed block 13, and a permanent magnet block 16 is fixedly provided at one end of the clamping strip 14 adjacent to the electromagnet block 15, and the electromagnet block 15 and the permanent magnet block 16 are matched;

[0032] A photoreceptor 17 is arranged outside the workbench 1, a light shielding column 18 is fixedly arranged at the center of the top surface of the photoreceptor 17, a photoresistor 19 is fixedly arranged on the top surface of the photoreceptor 17, a first processor 20 and a second processor 21 are fixedly arranged inside the photoreceptor 17, an output end of the photoresistor 19 is connected to an input end of the first processor 20, an output end of the first processor 20 is connected to an input end of the second processor 21, and an output end of the second processor 21 is connected to a current control end of the electromagnet disk 10 and an electromagnet block 15.

[0033] Furthermore, the four working columns 3 are arranged at the same distance from the load-bearing column 2 , the load-bearing column head 5 and the working column head 7 are both spherical, the weighing column 2 is used to support the middle of the workbench, and the four working columns 3 support the four sides of the workbench 1 .

[0034] Furthermore, the magnetic poles of the electromagnet disk 10 and the permanent magnet disk 11 are arranged in the same manner. The electromagnet disk 10 and the permanent magnet disk 11 are both arranged in a disc shape and are arranged vertically in a collinear manner. The repulsive force between the electromagnet disk 10 and the permanent magnet disk 11 is used to control the movement of the lifting column rod 6. When the input current of the electromagnet disk 10 is low, the magnetic force generated by the electromagnet disk 10 is relatively low, thereby controlling the lifting column rod 6 to descend. Conversely, when the input current of the electromagnet disk 10 is high, the lifting column rod 6 is controlled to descend.

[0035] Furthermore, the lifting column rod 6 is made of stainless steel material, the number of the card slots 12 is set to be multiple, and the corresponding lifting column rod 6 surface is evenly arranged vertically, and the inner wall of the working column 3 is provided with a solenoid 22. After the lifting column rod 6 is adjusted, it is convenient for the card strip 14 to be engaged with the corresponding height card slot 12, so as to fix the lifting column rod 6.

[0036] Furthermore, the photoreceptor 17 is disc-shaped, the shading column 18 is cylindrical, the number of the photoresistors 19 is multiple, and they are arranged in a surrounding manner on the top surface of the photoreceptor 17, so that sunlight can be irradiated on the photoreceptor 17. The sunlight will be projected on the surface of the photoreceptor 17 due to the shielding of the shading column 18, which makes it convenient for the projection to affect the photoresistor 19 and change the resistance value of the photoresistor 17.

[0037] The specific implementation method is as follows: when using the system, a solar panel for solar power generation is fixedly installed on a workbench 1, and sunlight is irradiated on the photoreceptor 17. The sunlight is blocked by the shading column 18 and a projection is generated on the surface of the photoreceptor 17. The projection causes the resistance value of part of the photoresistor 19 to change. The first processor 20 receives the resistance value of the photoresistor 19 for reception. The system first performs analog-to-digital conversion on the analog quantity of the collected photosensitive signal, stores the converted digital quantity in a group, and then compares it with the set azimuth value group to obtain the current azimuth information, and sends the signal to the processor 20. The information is sent to the second processor 21, the second processor 21 is electrically initialized, and then the signal sent is monitored in real time, the current input of the corresponding electromagnet disk 10 is adjusted, and the appropriate current is obtained through the amplification circuit to drive the electromagnet disk 10, and the electromagnet disk 10 generates magnetic force. The electromagnet disk 10 and the permanent magnet block 11 are arranged with the same poles, and the repulsive force of the same polar magnetism is used to push the lifting column rod 6 to move, and the lifting state of the lifting column rod 6 inside the four working columns 3 is controlled to realize the inclination of the workbench 1, and the corresponding direction of the workbench 1 is adjusted to face the sunlight, so as to improve the efficiency of solar power generation;

[0038] like Figure 5 In the shown magnetic shadow intelligent light tracking system, the two fixed blocks 13 are symmetrically arranged about the axis of the working column 3, and the fixed blocks 13 extend through both sides of the top of the working column 3. The clamping strip 14 is arranged through the fixed blocks 13, so that the clamping strip 14 can be conveniently clamped into the clamping slot 14 on the lifting column rod 6 to fix the lifting column rod 6.

[0039] Furthermore, the magnetic poles of the electromagnet block 15 and the permanent magnet block 16 are arranged in opposite directions, and the electromagnet block 15 and the permanent magnet block 16 are arranged horizontally in a collinear manner. By controlling the input current of the electromagnet block 15, the magnetic force generated by the electromagnet block 15 is used to adsorb the permanent magnet block 16 at one end of the clamping strip 14, so that the clamping strip 14 contracts, and the clamping connection of the clamping strip 14 to the clamping slot 12 is released, so as to facilitate the adjustment of the lifting column rod 6.

[0040] Furthermore, a return spring 23 is provided on one side of the permanent magnet block 16, and the return spring 23 is sleeved with the electromagnet block 15, so that when the electromagnet block 15 is powered off, the return spring 23 can be used to push the clamping strip 14 to move, so that the clamping strip 14 can be restored to clamp the clamping slot 12 on the lifting column rod 6, thereby fixing the lifting column 6.

[0041] The specific implementation method is as follows: when adjusting the height of the lifting column rod 6, the second processor 21 first controls the input current of the electromagnet block 15, and utilizes the attraction between the opposite magnetic poles of the electromagnet block 15 and the permanent magnet block 16 to shrink the clamping strip 14 to the inside of the fixed block 13, thereby releasing the clamping strip 14 from being clamped in the clamping slot 12 on the lifting column rod 6. Subsequently, the lifting column rod 6 uses the repulsive force between the electromagnet disk 15 and the permanent magnet disk 11 to adjust the height. After the electromagnet block 15 is powered off, the magnetism of the electromagnet block 15 is eliminated, and the compressed reset spring 23 pushes the clamping strip 14 to reset. The clamping strip 14 is re-clamped in the clamping slot 12 on the lifting column rod 6, which is convenient for fixing the lifting column rod 6, and further convenient for subsequently cutting off the input current to the electromagnet disk 10, saving unnecessary waste of electricity, and improving the stability of the workbench 1 after the direction is adjusted.

[0042] Working principle of the present invention:

[0043] Refer to the instruction manual Figure 1-8 When using the system, a solar panel for solar power generation is fixedly installed on the workbench 1, and sunlight is irradiated on the photoreceptor 17. The sunlight is blocked by the shading column 18 and a projection is generated on the surface of the photoreceptor 17. The projection causes the resistance value of part of the photoresistor 19 to change. The first processor 20 is used to process the resistance value change of the photoresistor 19 to obtain the solar position data. Subsequently, the first processor 20 inputs the solar position data into the second processor 21, and the second processor 21 is used to control the input working current of the electromagnet disk 10. The electromagnet disk 10 generates magnetic force. The electromagnet disk 10 and the permanent magnet block 11 are arranged with the same poles, and the repulsive force of the same pole magnetism is used to push the lifting column rod 6 to move, and the lifting state of the lifting column rod 6 inside the four working columns 3 is controlled to realize the inclination of the workbench 1, and the corresponding direction of the workbench 1 is adjusted to face the sunlight, thereby improving the efficiency of solar power generation.

[0044] Refer to the instruction manual Figure 5 When adjusting the height of the lifting column rod 6, the second processor 21 is used to control the input current of the electromagnet block 15, and the opposite magnetic poles of the electromagnet block 15 and the permanent magnet block 16 are attracted to each other, and the clamping strip 14 contracts to move inside the fixed block 13, so that the clamping strip 14 is released from the clamping slot 12 on the lifting column rod 6, which is convenient for lifting and lowering adjustment of the lifting column rod 6. After the electromagnet block 15 is powered off, the magnetism of the electromagnet block 15 is eliminated, and the reset spring 23 is used to push the clamping strip 14 to reset, and the clamping strip 14 is re-clamped into the clamping slot 12 on the lifting column rod 6, which is convenient for fixing the lifting column rod 6, and then it is convenient to cut off the input current of the electromagnet disk 10, saving unnecessary waste of electric energy, and improving the stability of the workbench 1 after the adjustment direction.
