[0027] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.
[0028] like Figures 1-4As shown, a specific embodiment of the present invention provides an aluminum alloy photovoltaic sunroom, comprising an aluminum alloy vertical beam 1, an aluminum alloy horizontal beam 2, a light-transmitting plate 3, a double-sided photovoltaic unit 4 and a light-guiding unit 5; the aluminum alloy horizontal beam 2 is arranged at a preset height of the aluminum alloy vertical beam 1, and the light-transmitting plate 3 is arranged on the outer surface of the aluminum alloy horizontal beam 2 and the aluminum alloy vertical beam 1; the double-sided photovoltaic unit 4 is arranged at the top of the aluminum alloy photovoltaic sunroom, comprising a double-sided photovoltaic panel 41 and a containing box 42, and the double-sided photovoltaic panel 41 is arranged on the top of the containing box 42; the light-guiding unit 5 includes a reflecting mechanism 51 and an optical fiber 52, and the reflecting mechanism 51 is arranged on the wall side of the aluminum alloy photovoltaic sunroom, for guiding the light on the wall side of the aluminum alloy photovoltaic sunroom into the optical fiber 52; one end of the optical fiber 52 is arranged at the reflecting mechanism 51, and the other end extends into the containing box 42.
[0029] This solution fully leverages the advantages of existing bifacial photovoltaic panels 41, directing light from the sides of the building to the back of the bifacial photovoltaic panels 41 located on the building's roof via optical fibers 52, thereby increasing power generation. The reflective mechanism 51 focuses light over a larger area, increasing light intensity in the optical fibers 52 and boosting photoelectric conversion efficiency.
[0030] In order to simplify the structure of the sunroom, the aluminum alloy vertical beam 1 is provided with a wire harness accommodating cavity 11 and a wire entry hole 12 on the side; the optical fiber 52 can enter the wire harness accommodating cavity 11 from the wire entry hole 12 and reach the top of the aluminum alloy photovoltaic sunroom, avoiding the optical fiber 52 being arranged outside the aluminum alloy vertical beam 1, affecting the overall appearance of the sunroom, and also protecting the relatively fragile optical fiber 52 and preventing the optical fiber 52 from being damaged by the outside.
[0031] Preferably, both the front and back surfaces of the bifacial photovoltaic panel 41 have photoelectric conversion capabilities. The housing 42 and the bifacial photovoltaic panel 41 together form a sealed space, and the inner surface of the housing 42 is provided with a reflective layer 43. Light in the optical fiber 52 is emitted from its end toward the back of the bifacial photovoltaic panel 41. Some of the outwardly emitted light is reflected by the reflective layer 43 back to the back of the bifacial photovoltaic panel 41 for photoelectric conversion, thereby improving the overall photoelectric conversion efficiency.
[0032] Combine Figure 5As shown, to allow light from the side of a building to be directed into an optical fiber 52 as needed, or to illuminate a room for daylighting, this embodiment provides a newly designed reflective mechanism 51. The reflective mechanism 51 comprises a reflective film 53, an elastic film 54, a housing 55, and a bend control mechanism 56. The edge of the reflective film 53 is secured to the housing 55 via the elastic film 54. A retaining sleeve 531 is provided on the bottom surface of the reflective film 53. The bend control mechanism 56 comprises an elastic strip 561 and a push-pull mechanism. The elastic strip 561 passes through the retaining sleeve 531, with one end secured to the housing 55 and the other end capable of translational movement driven by the push-pull mechanism, thereby varying its degree of curvature. The reflective film 53 is coated with a reflective coating and has low inherent elasticity. The elastic film 54 can be made of rubber to provide sufficient elastic deformation when the reflective film 53 is deformed.
[0033] The elastic strip 561 has a preset curvature in the initial state. Figure 6 and Figure 7 As shown, the push-pull mechanism includes: a threaded column 562 fixedly connected to one end of the elastic strip 561, and the surface of the threaded column 562 is provided with a limiting groove 563 arranged along the axial direction; a driving nut 564, which is sleeved on the surface of the threaded column 562 and has a first locking groove 565 on the side; a driving wheel 566, which is connected to the telescopic motor 567 and engages with the driving nut 564; a limiting plate 568, the bottom surface of which can move along the limiting groove 563, and the end can extend into the first locking groove 565.
[0034] Preferably, the push-pull mechanism also includes a reversing solenoid valve 569 and a reversing ring 560, and the reversing ring 560 is sleeved on the outside of the threaded column 562 and connected to the limit plate 568; a positioning ring 551 fixedly connected to the shell 55 is provided on the outside of the reversing ring 560, and the reversing solenoid valve 569 is provided on the positioning ring 551, and a second locking groove 552 is provided on the side of the positioning ring 551 facing the limit plate 568. The reversing solenoid valve 569 is also connected to the reversing ring 560, and can drive the limit plate 568 to move between the first locking groove 565 and the second locking groove 552 through the reversing ring 560.
[0035] The operating principle of the reflective mechanism 51 is as follows: when there is sufficient sunlight outside and the light from the side of the building is needed to generate electricity, the elastic strip 561 is in its initial position and slightly bends downward. Then, the reversing solenoid valve 569 drives the limit plate 568 to retract, locking it into the second locking groove 552. The threaded post 562 is now locked from rotation by the limit plate 568, forcing it to move only horizontally. The telescopic motor 567 rotates the drive nut 564 via the driving pulley 566. The drive nut 564, through its internal threads, drives the threaded post 562 toward the reflective film 53. Because the other end of the elastic strip 561 is fixed in position, it can only bend gradually, causing the reflective film 53 to sag downward, forming a concave lens that reflects and focuses light at the light-incoming end of the optical fiber 52. The light is then guided by the optical fiber 52 to the back of the bifacial photovoltaic panel 41.
[0036] When there is insufficient sunlight outside and the sunroom needs more light, the various components of the push-pull mechanism operate in reverse, causing the elastic strip 561 to return to its initial position. Next, the reversing solenoid valve 569 drives the limit plate 568 to extend, and the front end of the limit plate 568 is clamped into the first locking groove 565. At this time, the threaded column 562 and the drive nut 564 are locked together, and the telescopic motor 567 drives the drive nut 564 to rotate through the active wheel 566. The threaded column 562 rotates 180 degrees, causing the elastic strip 561 to be rotated to a slightly upwardly bent state. Then, following the steps of driving the reflective film 53 to bend downward, the reflective film 53 is made to bulge upward, forming a convex lens structure. The light from the outside on the side of the sunroom is scattered by the reflective film 53 with a convex lens structure, and enters the room more softly to provide lighting, meeting the indoor lighting needs on cloudy days.
[0037] With the above structure, the reflective mechanism 51 can focus or diverge light according to needs, has a compact structure, is low in cost, and has little deformation of the reflective film 53 and a long service life.
[0038] In order to ensure that the light-emitting film forms a reflective surface close to an arc shape, two sets of the push-pull mechanisms can be arranged perpendicularly to each other at the bottom of the reflective film 53 .
[0039] Furthermore, to ensure that sunlight incident at different angles remains aligned with the incident end of the optical fiber 52, the reflector 51 is connected to a swing mechanism 57, which comprises seated bearings 571, swing shafts 572, and a servo motor 573. The swing shafts 572 are positioned on either side of the reflector 51, extending into the seated bearings 571 and connected to the servo motor 573. Rotation of the servo motor 573 drives the reflector 51 to swing to a predetermined angle via the swing shafts 572.
[0040] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
