[0001] The present invention relates to the technical field of solar lighting power generation, and in particular to a solar lighting power generation system based on optical fibers. Background Art

[0002] Traditional natural lighting methods like windows and skylights are no longer sufficient to meet the lighting requirements of taller and denser buildings. Furthermore, artificial lighting methods like municipal power grids consume fossil fuels. To address this, solar daylighting systems are currently available that use optical fibers to directly guide sunlight into indoor spaces for illumination. These systems can also convert solar energy into electricity for use.

[0003] For example, the invention patent application with publication number CN102374479A discloses a sunlight conveyor and LED complementary lighting device, which consists of four parts: a pan-tilt head, an automatic tracking system, a fiber optic lighting device, and an LED light source. The fiber optic lighting device uses a focusing device to directly introduce sunlight into the room for lighting, while the LED light source uses photovoltaic panels for power supply.

[0004] Although this patent can successfully introduce sunlight into the room to provide light source for lighting, it still has the following shortcomings when used:

[0005] The focusing lens of the fiber optic lighting device is not protected against dust and water. During use, dust and other impurities are easily deposited on its surface, which not only has an adverse effect on the collection of sunlight, but also scratches the surface of the focusing lens, increasing the subsequent maintenance cost.

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0045] See also Figures 1-12 , the present invention provides a technical solution:

[0046] The solar lighting power generation system based on optical fiber includes a lighting power generation component 1, a U-shaped bracket 2, a horizontal angle adjustment motor 3 and an altitude angle adjustment motor 4; the lighting power generation component 1 is used to collect sunlight and use the sunlight to generate electricity. For example, the purpose of collecting sunlight is to use the optical fiber to introduce it into the room for lighting, and the use of sunlight to generate electricity is used to generate electricity and store the electricity in a battery (not shown in the figure), so that it can be used to provide indoor lighting at night with LEDs; the U-shaped bracket 2, the horizontal angle adjustment motor 3 and the altitude angle adjustment motor 4 are used together to adjust the position of the lighting power generation component 1 so that the front of the lighting power generation component 1 can always be kept in the direction of the sun; wherein, Figure 1 As shown, the solar power generation component 1 is rotatably set in the U-shaped bracket 2, and the altitude angle is adjusted by the altitude angle adjustment motor 4; the horizontal angle adjustment motor 3 is set at the bottom of the U-shaped bracket 2 and is used to adjust the horizontal angle of the U-shaped bracket 2. The above are all existing technologies and will not be repeated here.

[0047] The solar power generation component 1 includes a shell 11 and a front plate 12 and a rear plate 13 respectively arranged at the front and rear ends of the shell 11. The outer periphery of the front plate 12 and the rear plate 13 are sealed and fixedly connected to the inner surface of the shell 11. For example, sealing rubber can be provided at the connection position between the front plate 12 and the shell 11 and the connection position between the rear plate 13 and the shell 11.

[0048] A photovoltaic panel 121 and several focusing lenses 123 are provided on the front panel 12. The photovoltaic panel 121 is used to convert solar energy into electrical energy and store the electrical energy in a battery. Each focusing lens 123 is correspondingly provided with a secondary concentrator 14. The secondary concentrator 14 is installed on the rear panel 13. The tail end of each secondary concentrator 14 is connected to an optical fiber; wherein the secondary concentrator 14 is set at the focal position of the corresponding focusing lens 123. The focusing lens 123 focuses the sunlight once, and the secondary concentrator 14 is used to focus the sunlight twice. After focusing twice, the sunlight is introduced into the room through the optical fiber and is illuminated by lamps.

[0049] In this embodiment, the solar power generation component 1 further includes a skylight 122. The front panel 12 is a structure with a center recessed rearward. Specifically, the center recessed rearward of the front panel 12 forms a groove. The skylight 122 is fixedly mounted at the rear end of the groove. The focusing lens 123 is mounted on the skylight 122. The photovoltaic panel 121 surrounds the periphery of a transparent panel 124. The transparent panel 124 is sealed and mounted at the front end of the groove. The front side of the photovoltaic panel 121 is flush with the front surface of the transparent panel 124. The transparent panel 124 can be made of transparent acrylic.

[0050] An intermediate tube 15 is provided at the center of the transparent plate 124, and the rear end of the intermediate tube 15 passes through the lighting panel 122 and extends to the interior of the outer shell 11. In some embodiments, the rear end of the intermediate tube 15 can be sealed with the inner cavity of the outer shell 11 by means of a sealing installation circular plate to prevent the air inside the intermediate tube 15 from entering the inner cavity of the outer shell 11.

[0051] The front end face of the intermediate cylinder 15 is flush with the front surface of the transparent plate 124, and a round rod 16 is provided on the front side of the intermediate cylinder 15. The adjusting driving component 5 drives the round rod 16 to switch between being coaxial or perpendicular to the intermediate cylinder 15; specifically, when the round rod 16 is coaxial with the intermediate cylinder 15, it cooperates with the multiple photoresistors 182 surrounding the round rod 16 to form a sunlight tracking component, which is used to cooperate with the horizontal angle adjustment motor 3 and the altitude angle adjustment motor 4 to adjust the position of the light-collecting and power generation component 1 so that the front of the light-collecting and power generation component 1 can always be kept in the direction facing the sun; when the round rod 16 is perpendicular to the intermediate cylinder 15, it can cooperate with the long brush 6 to clean the dust on the surface of the transparent plate 124 by rotation. At this time, the long brush 6 can brush the front surface of the transparent plate 124 and the front side of the photovoltaic panel 121.

[0052] The working principle of the sunlight tracking component in the above scheme is as follows: when the round rod 16 is coaxial with the intermediate cylinder 15, the round rod 16 as a whole remains perpendicular to the front surface of the front plate 12. At this time, the front surface of the front plate 12 faces the sun, and the sunlight is perpendicular to the front plate 12. At this time, the shadow formed by the round rod 16 on the front surface of the front plate 12 will not block any photoresistor 182, that is, the light intensity and light receiving area received by each photoresistor 182 are the same; once the angle between the front surface of the front plate 12 and the sunlight is not 90 degrees, the round rod 16 will form a shadow part on the front surface of the front plate 12, and the shadow part will cause at least one photoresistor 182 to be blocked. Unable to receive direct sunlight, that is, the light intensity and light receiving area received by each photoresistor 182 are different, so that the resistance value of the photoresistor 182 that cannot receive light is different from that of the photoresistor 182 that can receive light. At this time, the microcontroller processes and analyzes the signals with different resistance values ​​of the photoresistors 182 and controls the horizontal angle adjustment motor 3 and the altitude angle adjustment motor 4 to make corresponding action changes until the sunlight is perpendicular to the front plate 12; and, since the length of the round rod 16 is long, the angle between the sunlight and the front plate surface of the front plate 12 is not 90°, then the round rod 16 will form a shadow on the front plate surface of the front plate 12, and the overall accuracy is high.

[0053] Furthermore, in some embodiments, when there is sufficient sunshine, the round rod 16 remains coaxial with the intermediate cylinder 15, and when it rains, the round rod 16 can be adjusted to be perpendicular to the intermediate cylinder 15, and then the round rod 16 is driven to rotate, and the front surface of the transparent plate 124 and the front side of the photovoltaic panel 121 are brushed using the long brush 6.

[0054] In the above scheme, the multiple focusing lenses 123 are effectively protected by the transparent plate 124, which can prevent dust and the like from falling onto the surface of the focusing lens 123 and affecting the lighting; further, the round rod 16 is set, and the round rod 16 can be adjusted to be coaxial or perpendicular to the intermediate tube 15. When the round rod 16 is coaxial with the intermediate tube 15, it cooperates with the multiple photoresistors 182 surrounding the round rod 16 to form a sunlight tracking component, and then cooperates with the horizontal angle adjustment motor 3 and the altitude angle adjustment motor 4 to adjust the position of the lighting and power generation component 1 so that the front of the lighting and power generation component 1 can always be kept in the direction facing the sun; when the round rod 16 is perpendicular to the intermediate tube 15, it can cooperate with the long brush 6 to clean the dust on the surface of the transparent plate 124 by rotation, and at this time the long brush 6 can also brush the front side of the photovoltaic panel 121.

[0055] A through groove 161 is provided at one end of the round rod 16 close to the intermediate tube 15; when the round rod 16 is coaxial with the intermediate tube 15, the long brush 6 is completely received inside the through groove 161, thereby ensuring that the long brush 6 will not be directly exposed to sunlight. Therefore, when the round rod 16 is coaxial with the intermediate tube 15, the long brush 6 will not form a shadow on the front panel surface of the front panel 12; when the round rod 16 is perpendicular to the intermediate tube 15, the bristles of the long brush 6 are in contact with the surface of the transparent plate 124. At this time, the round rod 16 does not contact the photovoltaic panel 121 and the transparent plate 124, and only the bristles of the long brush 6 are in contact with the surface of the photovoltaic panel 121 and the transparent plate 124.

[0056] A fixed ring plate 18 is coaxially fixed to the interior of the intermediate tube 15. A sleeve 181 is coaxially fixed to the front side of the fixed ring plate 18. Multiple photoresistors 182 are mounted on the fixed ring plate 18, and the multiple photoresistors 182 are located within the sleeve 181. The front end of the sleeve 181 does not protrude from the front end of the intermediate tube 15. This arrangement provides protection for the multiple photoresistors 182 and prevents sunlight from being reflected and striking the photoresistors 182, further improving overall accuracy.

[0057] The adjusting drive component 5 includes an electric push rod 501, a motor 502, and a first gear 504 and a second gear 505 that are meshed together; wherein, the electric push rod 501 is fixedly installed inside the intermediate cylinder 15, and the motor 502 is fixedly installed on the output rod of the electric push rod 501 through the support plate 503; the electric push rod 501 can drive the motor 502 to move forward and backward together; the first gear 504 is coaxially connected to the output rod of the electric push rod 501 through the first bearing seat 506, and the second gear 505 is coaxially fixedly connected to the output shaft of the motor 502; therefore, the electric push rod 501 can not only push the first gear 504 and the motor 502 to move forward and backward synchronously, but also use the motor 502 to drive the first gear 504 and the second gear 505 to rotate.

[0058] The front end face of the first gear 504 is fixedly connected with a strip plate 511, which extends to the inside of the through groove 161; the strip plate 511 is used to limit the position of the long brush 6. When the round rod 16 is coaxial with the intermediate tube 15, the long brush 6 is completely received in the inside of the through groove 161 under the action of the strip plate 511; when the round rod 16 is perpendicular to the intermediate tube 15, the strip plate 511 releases the lock on the long brush 6, so that the bristles of the long brush 6 can contact the surfaces of the photovoltaic panel 121 and the transparent plate 124.

[0059] When the output rod of the electric push rod 501 drives the strip plate 511 to retract, the round rod 16 changes from being coaxial with the intermediate tube 15 to being perpendicular to the intermediate tube 15; when the output rod of the electric push rod 501 drives the strip plate 511 to extend, the round rod 16 changes from being perpendicular to the intermediate tube 15 to being coaxial with the intermediate tube 15.

[0060] Furthermore, a rotating plate 17 is coaxially rotated inside the intermediate cylinder 15. For example, the rotating plate 17 can be rotatably connected to the inner wall of the intermediate cylinder 15 through a sealed bearing. A rectangular block 507 slides through the middle of the rotating plate 17, and the rear end of the rectangular block 507 is fixedly connected to the first gear 504; a docking block 510 is fixed to the rear end of the strip plate 511, and a rack 508 and a square bar 509 are fixed between the docking block 510 and the rectangular block 507.

[0061] A pin 513 is fixedly connected to the rear end of the through slot 161. The axial direction of the pin 513 is perpendicular to the axial direction of the round rod 16. A third gear 516 is fixedly connected to the pin 513 and meshes with the rack 508. A fixed block 515 is rotatably connected to the pin 513 via a second bearing seat 514. The fixed block 515 is fixedly connected to the rotating plate 17. This allows the pin 513 to remain axially fixed to the intermediate cylinder 15.

[0062] Furthermore, a beveled plug 512 is provided at the front end of the strip plate 511, and a positioning seat 61 adapted to the beveled plug 512 is fixed on the long brush 6; the long brush 6 is elastically connected to the inner wall of the through groove 161 through an elastic component; when the output rod of the electric push rod 501 drives the strip plate 511 to retract, the beveled plug 512 withdraws from the positioning seat 61, so that the elastic component releases the elastic force to push the long brush 6 to protrude from the outer peripheral surface of the round rod 16; when the output rod of the electric push rod 501 drives the strip plate 511 to extend forward, the beveled plug 512 is inserted into the positioning seat 61, so that the long brush 6 is completely received inside the through groove 161.

[0063] The relevant structures set up in the above scheme can not only realize the rotation of the round rod 16, but also ensure that structures such as the rack 508 and the third gear 516 will not form shadows on the transparent plate 124, that is, the rack 508 and the third gear 516 and other structures can be completely accommodated inside the through groove 161 without affecting the normal operation of the photoresistor 182.

[0064] The elastic component includes a raised strip 517 and an elastic member 518. The elastic member 518 can be a straight spring. The raised strip 517 is fixedly connected to the inner wall of the through groove 161. The two ends of the elastic member 518 are fixedly connected to the raised strip 517 and the long brush 6 respectively.

[0065] The working principle of the adjustment drive component 5 is as follows: when the round rod 16 is to be adjusted from being coaxial with the intermediate cylinder 15 to being perpendicular to the intermediate cylinder 15, the electric push rod 501 is first started to pull the motor 502, the first gear 504, the second gear 505 and the strip plate 511 and other structures to move backward. At this time, the oblique plug 512 gradually withdraws from the interior of the positioning seat 61, and the elastic force on the elastic member 518 is released, pushing the long brush 6 to move along the radial direction of the round rod 16, so that at least part of the bristles of the long brush 6 protrude from the circumference of the round rod 16. At the same time, the backward movement of the rack 508 drives the third gear 516 to rotate. Since the third gear 516 is rotated through the pin 51 3 is fixedly connected to the round rod 16, so the round rod 16 will also rotate with the third gear 516 until the round rod 16 is perpendicular to the intermediate cylinder 15. At this time, the electric push rod 501 is turned off, and the bristles of the long brush 6 will be pressed against the surface of the photovoltaic panel 121 and the transparent plate 124 by the action of the elastic member 518. Then, the motor 502 is started to drive the first gear 504, the rectangular block 507, the rotating plate 17, the rack 508, the third gear 516 and the strip plate 511 to rotate, and at the same time, the round rod 16 will be driven to rotate together through the pin shaft 513, so that the surface of the photovoltaic panel 121 and the transparent plate 124 can be scrubbed by the rotating long brush 6.

[0066] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
