[0013] A method for using a self-following sunlight optical fiber collection system comprises the following steps: S1.

The continuous rotation of the spherical transparent cover changes the sunlight irradiation area constantly, avoiding the concentration of thermal stress caused by long-term local heating. The light and heat load is evenly distributed through rotation, reducing the micro cracks or optical distortion caused by the temperature difference deformation of the spherical transparent cover. At the same time, the air flow disturbance generated by the rotation can accelerate the heat dissipation of the surface, preventing the high temperature area from affecting the working stability of the internal sunlight fiber collection board. The continuous rotation of the spherical transparent cover can make the illumination area change periodically, realize the distribution of ultraviolet radiation dose, delay the material degradation process, and extend the service life of the spherical transparent cover. It can avoid the situation where the traditional fixed cover is exposed to ultraviolet radiation in the same area for a long time, which will cause local aging of the material (such as yellowing and decreased light transmittance), and can further maintain the collection efficiency of the solar fiber collection board.

DETAILED DESCRIPTION

[0018] 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.

[0019] Example: like Figure 1-17 As shown, this embodiment proposes a self-following sunlight optical fiber collection system, including a placement seat 10, a spherical transparent cover 30 is arranged on the placement seat 10, and a sunlight optical fiber collection plate 70 is arranged inside the spherical transparent cover 30; A cleaning rack 20 is arranged on the placement seat 10, and the surface of the spherical transparent cover 30 contacts the cleaning rack 20. A support plate 72 is arranged on the placement seat 10, and a driving adjustment component 60 is arranged on the support plate 72. The driving adjustment component 60 is connected to the sunlight fiber optic collection plate 70. A transmission gear 50 is arranged in the placement seat 10, and the spherical transparent cover 30 cooperates with the transmission gear 50, and the transmission gear 50 also cooperates with the driving adjustment component 60. The driving adjustment component 60 drives the sunlight fiber optic collection plate 70 to adjust its direction and drives the transmission gear 50 to rotate, so that the spherical transparent cover 30 rotates in the cleaning rack 20 to remove impurities.

[0020] In this embodiment, when the sunlight fiber collection board 70 is needed to collect sunlight, the placement seat 10 is placed in the area where it needs to be installed, and the driving adjustment component 60 is connected to the support plate 72, and the sunlight fiber collection board 70 is placed on the driving adjustment component 60, so that the sunlight fiber collection board 70 is placed on the placement seat 10, and then the driving adjustment component 60 is turned on for testing to observe whether the sunlight fiber collection board 70 adjusts its direction and whether the transmission gear 50 rotates. If the sunlight fiber collection board 70 does not adjust its direction and the transmission gear 50 does not rotate, the driving adjustment component 60 is replaced until the sunlight fiber collection board 70 can adjust its direction and the transmission gear 50 can rotate; After the above test steps are completed, the spherical transparent cover 30 is placed on the placement seat 10, and the sunlight optical fiber collection plate 70 is wrapped by the spherical transparent cover 30, and then the cleaning rack 20 is placed on the placement seat 10, and the spherical transparent cover 30 is wrapped by the cleaning rack 20; After the above installation steps are completed, the drive adjustment component 60 is turned on again to observe whether the spherical transparent cover 30 rotates during the adjustment of the direction of the sunlight optical fiber collection plate 70. If the spherical transparent cover 30 does not rotate, repeat the spherical transparent cover 30 installation steps until the spherical transparent cover 30 can rotate as the sunlight optical fiber collection plate 70 adjusts its direction; By driving the adjustment component 60 to link the transmission gear 50 mechanism, the sunlight fiber collection plate 70 can automatically adjust the angle according to the sun's position, and synchronously drive the spherical transparent cover 30 to rotate in the cleaning frame 20. This dual-axis linkage mechanism enables the system to have a real-time light tracking function, and uses the cleaning frame 20 to continuously scrape the surface of the spherical transparent cover 30 to effectively remove environmental pollutants such as dust, rain and snow, so that adaptive tracking and self-cleaning are integrated, ensuring that the sunlight fiber collection plate 70 is always in a high light transmittance state, significantly improving the light energy collection efficiency, avoiding the light energy loss caused by the accumulation of impurities such as dust, and reducing the frequency and cost of manual cleaning, and improving the self-maintenance ability of the system; The spherical transparent cover 30 can provide physical protection for the sunlight fiber collection board 70, preventing external collisions, scratches, etc. from directly acting on the sunlight fiber collection board 70, reducing the risk of physical damage, and extending the service life of the sunlight fiber collection board 70. In addition, under the limit of the cleaning frame 20, an external mesh support skeleton can be formed to enhance the overall rigidity of the spherical transparent cover 30, which can improve the structural stability under extreme weather (such as typhoons and blizzards), further improve the protection ability of the sunlight fiber collection board 70, and effectively extend the service life of the sunlight fiber collection board 70; The continuous rotation of the spherical transparent cover 30 causes the sunlight irradiation area to change continuously, thus avoiding the concentration of thermal stress caused by long-term local heating. The light and heat load is evenly distributed by rotation, thus reducing the micro cracks or optical distortion caused by the temperature difference deformation of the spherical transparent cover 30. At the same time, the air flow disturbance generated by the rotation can accelerate the heat dissipation of the surface, thus preventing the high temperature area from affecting the working stability of the internal sunlight optical fiber collection board 70. The continuous rotation of the spherical transparent cover 30 can make the illumination area change periodically, realize the distribution of ultraviolet radiation dose, delay the material degradation process, and extend the service life of the spherical transparent cover 30. It can avoid the situation where the traditional fixed cover is exposed to ultraviolet radiation in the same area for a long time, which will cause local aging of the material (such as yellowing and decreased light transmittance), and can further maintain the collection efficiency of the solar fiber collection board 70.

[0021] Specifically, a plurality of groups of focusing lenses 74 are evenly arranged on the sunlight optical fiber collection board 70, and a light tracking sensor device 75 is arranged at the center of the sunlight optical fiber collection board 70; The sunlight fiber optic collection plate 70 is also provided with a fiber optic mounting plate 77, and a plurality of mounting rods 73 are evenly arranged between the fiber optic mounting plate 77 and the sunlight fiber optic collection plate 70. A plurality of parallel light lenses 76 are evenly arranged on the fiber optic mounting plate 77, and the positions of the plurality of parallel light lenses 76 match the positions of the plurality of focusing lenses 74, and the parallel light lenses 76 are connected with optical fibers.

[0022] In this embodiment, the condensing lens 74 is evenly distributed and strictly matched with the position of the parallel light lens 76 to form a focusing-collimating optical path system to achieve secondary optical processing of sunlight. The condensing lens 74 converges the incident sunlight to the focal area to increase the energy density per unit area, and the parallel light lens 76 converts the focused divergent light into a parallel light beam to match the numerical aperture of the optical fiber and reduce the coupling reflection loss at the end face of the optical fiber. Of course, the evenly distributed mounting rods 73 can ensure that the distance between the optical fiber mounting plate 77 and the sunlight optical fiber collection plate 70 is constant, maintain the precise alignment of the focus of the focusing lens 74 and the entrance of the parallel light lens 76, and avoid the optical path deviation caused by mechanical deformation; Of course, the light-chasing sensor device 75 is placed at the center of the collection board. By monitoring the position of the focusing spot in the central area (such as a four-quadrant detector or an image sensor), the sun's azimuth deviation is fed back in real time, and the adjustment component 60 is driven to adjust the angle of the sunlight fiber collection board 70. The center position can reflect the overall optical path deviation to the greatest extent and improve the light-chasing accuracy.

[0023] Specifically, the drive adjustment assembly 60 includes an adjustment housing 62, a first dual-axis reducer 61 is disposed in the adjustment housing 62, an adjustment bracket 78 is further disposed on the adjustment housing 62, the adjustment bracket 78 is connected to the optical fiber mounting plate 77, and both ends of the adjustment bracket 78 are respectively connected to two sets of driving shafts of the first dual-axis reducer 61; The adjusting housing 62 is also provided with a second double-shaft reducer 63, the second double-shaft reducer 63 is connected to the support plate 72, and a set of driving shafts of the second double-shaft reducer 63 is connected to the adjusting housing 62; The first double-shaft reducer 61 and the second double-shaft reducer 63 are both provided with servo motors.

[0024] In this case, a processor for receiving the light-chasing sensor device 75 is provided in the adjustment housing 62 . The processor processes the signal and controls the two sets of servo motors to start so as to adjust the direction of the sunlight fiber optic collection board 70 .

[0025] In this embodiment, the first double-axis reducer 61 and the second double-axis reducer 63 are arranged in a nested manner, and the dual servo motors are independently driven to realize the four-quadrant dynamic decoupling control of the sunlight optical fiber collection board 70 in the pitch angle and azimuth angle; The first dual-axis reducer 61 applies symmetrical torque to the optical fiber mounting plate 77 by adjusting the driving shafts at both ends of the bracket 78 to ensure that the optical axis center does not deviate during the pitch adjustment of the optical fiber mounting plate 77. The second dual-axis reducer 63 drives the entire assembly to rotate around the vertical axis, i.e., the driving axis center of the second dual-axis reducer 63, by adjusting the linkage between the housing 62 and the support plate 72, to achieve full coverage of the azimuth angle. Of course, after the axis of the second dual-axis reducer 63 rotates, the transmission gear 50 is driven to rotate, so as to control the spherical transparent cover 30 to rotate.

[0026] Specifically, the placement seat 10 includes a circular bottom plate 11, a support leg 71 is provided on the support plate 72, the support leg 71 is connected to the circular bottom plate 11, and a plurality of groups of transmission gears 50 are evenly rotated and arranged on the circular bottom plate 11; The circular bottom plate 11 is provided with a mounting ring 12, the circular bottom plate 11 is provided with a sealing gasket 112, the circular bottom plate 11 is evenly provided with a plurality of first mounting holes 111, the mounting ring 12 is evenly provided with a plurality of second mounting holes 121, the positions of the first mounting holes 111 and the second mounting holes 121 match, and the first mounting holes 111 and the second mounting holes 121 are connected by bolts.

[0027] In this embodiment, a plurality of first mounting holes 111 evenly provided on the circular base plate 11 are bolted to the corresponding second mounting holes 121 on the mounting ring 12 to form a standardized positioning reference, thereby ensuring that the mounting ring 12 is coaxial with the circular base plate 11, and the design allows the mounting ring 12 to be quickly disassembled, assembled and replaced.

[0028] Specifically, the mounting ring 12 is provided with a limit ring 13, the mounting ring 12 is provided with a placement protrusion ring 122, the placement protrusion ring 122 is provided with an annular placement groove 123, the spherical transparent cover 30 is provided with an annular placement portion 32, and the annular placement portion 32 is rotatably arranged in the annular placement groove 123; The placement protrusion ring 122 is evenly provided with first limiting holes 124 , and the limiting ring 13 is evenly provided with multiple groups of second limiting holes 131 . The positions of the first limiting holes 124 and the second limiting holes 131 match, and the first limiting holes 124 and the second limiting holes 131 are connected by bolts.

[0029] In this embodiment, the annular placement portion 32 is placed in the annular placement groove 123, and then the limiting ring 13 is used to limit the position, so that the spherical transparent cover 30 is rotatably set on the mounting ring 12. Of course, a rotary sealing structure is used here; Of course, the first limiting hole 124 and the second limiting hole 131 are connected by bolts to form a standardized positioning reference, so that the annular placement portion 32 can rotate normally in the annular placement groove 123 .

[0030] Specifically, the spherical transparent cover 30 is provided with an annular connecting portion 31, the annular placing portion 32 is provided on the annular connecting portion 31, and the inner wall of the annular connecting portion 31 is provided with an inner gear ring 33; A driving gear 51 is disposed at the center of the circular bottom plate 11, and the driving gear 51 is also meshed with multiple sets of transmission gears 50, and multiple sets of transmission gears 50 are meshed with the inner gear ring 33. A one-way bearing 52 is disposed in the driving gear 51, and the one-way bearing 52 is connected to the driving shaft of the second dual-axis reducer 63; The second dual-axis speed reducer 63 is started, so that the spherical transparent cover 30 rotates as the adjustment housing 62 rotates to adjust the direction.

[0031] In this case, the limiting ring 13 is formed by welding two groups of half rings. When the spherical transparent cover 30 is installed, the limiting ring 13 is preset on the annular connecting portion 31 of the spherical transparent cover 30; In this embodiment, a closed planetary gear train transmission chain is formed by the driving gear 51, the circumferentially uniformly distributed transmission gears 50 and the inner gear ring 33, and the output torque of the second dual-axis reducer 63 is dispersed to N groups of transmission gears 50 for synchronous transmission, so that the torque borne by a single transmission gear 50 is reduced to 1 / N of the total torque, which significantly suppresses the risk of tooth surface pitting and tooth breakage, and can effectively improve the life of the transmission system; Of course, the driving gear 51 is embedded with a one-way bearing 52 (such as a needle roller overrunning clutch), which limits the transmission chain to only transmit power along a preset rotation direction (such as clockwise), that is, the spherical transparent cover 30 is controlled to rotate in a single direction, so as to prevent the spherical transparent cover 30 from rotating to the original direction when the second dual-axis reducer 63 drives the sunlight optical fiber collection board 70 to rotate to the original direction, so as to transmit sunlight to the internal sunlight optical fiber collection board 70 through different positions of the spherical transparent cover 30; Of course, the second dual-axis reducer 63 realizes the rigid synchronous drive of the azimuth adjustment of the sunlight fiber optic collection plate 70 and the rotation of the spherical transparent cover 30 through the power coupling of the driving shaft-one-way bearing 52-planetary gear system, which can ensure that the cleaning frequency of the cleaning rack 20 on the surface of the spherical transparent cover 30 is matched with the change of the sun's azimuth in real time, eliminating the transmittance attenuation caused by cleaning delay.

[0032] Specifically, the cleaning frame 20 includes a clamping ring 21, and a clamping rod 34 is provided on the spherical transparent cover 30, and the clamping ring 21 is rotatably sleeved on the clamping rod 34; The clamping ring 21 is evenly provided with a plurality of cleaning rods 22. A cleaning scraper 221 is provided on one end surface of the cleaning rod 22 facing the spherical transparent cover 30. The cleaning scraper 221 is in close contact with the surface of the spherical transparent cover 30. The spherical transparent cover 30 rotates so that different positions of the spherical transparent cover 30 are in contact with the cleaning scraper 221 to remove impurities. The cleaning rod 22 is provided with a cleaning plate 23 , and the cleaning plate 23 is connected to the limiting ring 13 via bolts.

[0033] In this embodiment, the cleaning scraper 221 is made of a flexible material (such as silicone or polyurethane) and contacts the surface of the spherical transparent cover 30. The cleaning process is performed when the spherical transparent cover 30 rotates, and the periodic contact between its outer surface and the cleaning scraper 221 can also evenly distribute the mechanical wear area, delay local aging, and increase the overall life of the spherical transparent cover 30.

[0034] Specifically, a compression sleeve 40 is provided on the outer wall of the compression rod 34, and the compression sleeve 40 is threadedly connected to the compression rod 34. A rotating ring 41 is provided on the compression sleeve 40, and the rotating ring 41 contacts the compression ring 21, so that the compression sleeve 40 rotates as the compression rod 34 rotates; A plurality of groups of elastic levers 42 are disposed on the outer wall of the compression sleeve 40. The elastic levers 42 are in contact with the cleaning levers 22 to press the cleaning levers 22 against the surface of the spherical transparent cover 30. The clamping sleeve 40 is further provided with two sets of positioning bolts 43 , and the two sets of positioning bolts 43 are both threadedly connected to the clamping rod 34 .

[0035] In this embodiment, a distributed elastic pressing system is formed by contacting the cleaning rod 22 with multiple groups of toggling elastic rods 42 on the outer wall of the compression sleeve 40. The toggling elastic rods 42 are made of high yield strength spring steel sheets. During the rotation of the spherical transparent cover 30, the deformation of the toggling elastic rods 42 compensates for the surface deformation or assembly tolerance of the spherical transparent cover 30 in real time, maintaining a constant contact pressure between the cleaning scraper 221 and the surface of the spherical transparent cover 30, and ensuring cleaning uniformity. Of course, the toggle elastic rod 42 rotates with the rotation of the spherical transparent cover 30, and the contact between the toggle elastic rod 42 and the cleaning rod 22 generates vibration, and the high-frequency micro-amplitude vibration causes the dust, ice crystals and other tiny particles on the contact interface between the cleaning rod 22 and the toggle elastic rod 42 to detach from the attachment, forming a self-cleaning effect, avoiding the accumulation of impurities and uneven contact pressure, ensuring that the pressing force of the cleaning scraper 221 on the surface of the spherical transparent cover 30 is stable, and at the same time, the force generated by the vibration acts on the interface between the cleaning scraper 221 and the spherical transparent cover 30, exerting a periodic peeling force on the sticky pollutants (such as resin, shellac), so as to improve the cleaning ability; Of course, the sound waves generated by the contact and vibration of the elastic rod 42 and the cleaning rod 22 can prevent birds, insects, etc. from staying, achieve full-dimensional biological interference protection, and effectively eliminate bird droppings pollution and insect corpses.

[0036] A method for using a self-following sunlight optical fiber collection system comprises the following steps: S1. One-time installation: Place the circular bottom plate 11 in the area to be installed, and place the sunlight optical fiber collection plate 70 and the driving adjustment assembly 60 in the circular bottom plate 11, so that the driving gear 51 is meshed with the multiple transmission gears 50; S2. Secondary installation: The annular placement portion 32 of the spherical transparent cover 30 is placed in the annular placement groove 123, and the limiting ring 13 is connected to the mounting ring 12, so that the spherical transparent cover 30 is rotatably arranged on the mounting ring 12; S3, three installations: The clamping ring 21 is sleeved on the outer wall of the clamping rod 34, so that the multiple sets of cleaning scrapers 221 are arranged toward the spherical transparent cover 30, and the cleaning plates 23 are connected to the limiting ring 13 in S2 until the multiple sets of cleaning plates 23 are installed; S4. Positioning: After S3 is completed, a compression sleeve 40 is threadedly sleeved on the outer wall of the compression rod 34 until the rotating ring 41 contacts the compression ring 21, the elastic rod 42 is moved to contact the cleaning rod 22, and the positioning bolt 43 is installed between the compression sleeve 40 and the compression rod 34; S5. Assembly: After S4 is completed, the mounting ring 12 is sleeved on the outside of the sunlight optical fiber collection plate 70 after S1 is completed, and the mounting ring 12 is driven down until the mounting ring 12 contacts the circular bottom plate 11, and the inner gear ring 33 meshes with the multiple sets of transmission gears 50, and then the mounting ring 12 is connected to the circular bottom plate 11; S6. One test: After S1 is completed, the driving adjustment component 60 is turned on to observe whether the driving adjustment component 60 can drive the sunlight optical fiber collection board 70 to adjust the direction and whether it can drive the transmission gear 50 to rotate. If it cannot drive the sunlight optical fiber collection board 70 to adjust the direction and cannot drive the transmission gear 50 to rotate, the driving adjustment component 60 is replaced; S7, Secondary test: After S5 is completed, the driving and adjusting component 60 is turned on again to observe whether the driving and adjusting component 60 can drive the spherical transparent cover 30 to rotate. If it cannot drive the spherical transparent cover 30 to rotate, repeat S2, S3, and S4 until the driving and adjusting component 60 can drive the sunlight fiber optic collection plate 70 to adjust its direction and rotate the spherical transparent cover 30 in the process.

[0037] In this embodiment, the meshing positioning of the drive gear 51 and the transmission gear 50, the rotational sealing cooperation between the spherical transparent cover 30 and the mounting ring 12, and the elastic compression adjustment of the cleaning scraper 221 are achieved through a step-by-step assembly process, and the deformation adaptive compensation mechanism of the threaded compression sleeve 40 and the toggle elastic rod 42 is combined to ensure the constant cleaning contact pressure; a two-stage test is used to verify the power output, transmission chain effectiveness and light chasing-self-cleaning synchronization of the drive adjustment component 60, and assembly errors and component failures are eliminated in a hierarchical manner; the modular bolt connection structure of the mounting ring 12 and the closed-loop assembly-test correction process are used to achieve system precision control, fault tolerance and on-site repairability, ultimately ensuring the coordinated operation of the planetary gear system power distribution and the real-time self-cleaning function, and effectively suppressing the transmittance attenuation and systemic failure risks.

[0038] Specifically, in S7, during the rotation of the spherical transparent cover 30, the cleaning rod 22 is manually touched to feel whether vibration is generated between the elastic rod 42 and the cleaning rod 22. If vibration is not generated, S4 is repeated until vibration is generated between the elastic rod 42 and the cleaning rod 22 when the spherical transparent cover 30 rotates.

[0039] In this embodiment, the vibration feedback between the elastic rod 42 and the cleaning rod 22 is detected by artificial touch to verify the assembly effectiveness of the elastic clamping structure: the existence of vibration indicates that the elastic rod 42 and the cleaning rod 22 form a periodic contact-separation movement, generating high-frequency micro-mechanical vibrations. On the one hand, this vibration promotes the shear peeling effect of the pollutants (such as resin, shellac) adhered to the surface of the cleaning scraper 221 and the spherical transparent cover 30, thereby enhancing the cleaning ability; on the other hand, tactile perception is used to confirm that the elastic rod 42 is in a deformation compensation working state, ensuring that the clamping force of the cleaning rod 22 is within the preset threshold range, avoiding the increase of friction resistance caused by over-tight assembly or cleaning failure caused by too loose assembly, thereby establishing a direct correlation verification mechanism between assembly quality and function realization, and improving the system operation reliability.
