Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, and specifically to an amorphous silicon perovskite superimposed solar cell with a protective structure. Background Technology

[0002] Amorphous silicon perovskite laminated solar panels achieve broader spectrum absorption of sunlight and more efficient utilization of light energy through the composite layering of an upper perovskite photovoltaic layer and a lower amorphous silicon photovoltaic layer. Perovskite photovoltaic coating is an emerging photovoltaic material capable of efficiently absorbing visible light from sunlight, thus overcoming the limitation of amorphous silicon materials, which can only absorb infrared light. However, perovskite materials have significant drawbacks: they are easily oxidized and susceptible to water damage, particularly from rain in open-air environments. Furthermore, they are heat-sensitive, easily damaged by changes in physical volume due to large temperature differences. Current technologies typically address these drawbacks by covering the panels with high-strength, translucent materials. While this passive protection can mitigate some of the shortcomings of perovskite photovoltaic layers, it still inevitably leads to equipment damage in harsh environments, making it more vulnerable than traditional amorphous silicon materials and exhibiting extremely poor resistance to harsh environments, resulting in high equipment costs. Therefore, a protective structure needs to be designed for perovskite-amorphous silicon laminated photovoltaic panels. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an amorphous silicon perovskite superimposed solar cell with a protective structure. This structure utilizes a liftable support structure to mount the photovoltaic panel and a push-pull step-type additional protective structure to provide additional protection for the photovoltaic panel.

Detailed Implementation

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] like Figure 1-8 As shown, the specific implementation adopts the following technical solution:

[0041] This specific embodiment includes a frame 10, a mounting frame 2, a photovoltaic panel 1, a support mechanism 3, and a protective mechanism 4. There are two mounting frames 2 arranged symmetrically in front and behind inside the frame 10. The photovoltaic panel 1 is arranged between the mounting frames 2 on the front and rear sides. The support mechanism 3 is arranged on the mounting frame 2 and cooperates with the photovoltaic panel 1. The protective mechanism 4 cooperates with the photovoltaic panel 1 and is arranged on the mounting frame 2.

[0042] The support mechanism 3 includes support shafts 3-1, support arms 3-2, connecting shafts 3-3, and support drive motors 3-4. Two support shafts 3-1 are grouped together and screwed onto the mounting brackets 2 on the front and rear sides via bearings. Two sets of support shafts 3-1 are respectively located on the left and right ends of the mounting brackets 2. Support arms 3-2 are fixedly mounted on the support shafts 3-1. The connecting shaft 3-3 is fixedly mounted on the end of the support arm 3-2 away from the support shaft 3-1. The support arm 3-2 is screwed onto the side frame of the photovoltaic panel 1 via the connecting shaft 3-3. Two support drive shafts 5 are respectively located below the two sets of support shafts 3-1 and screwed onto the frame 10 via bearings. The front and rear ends of one support drive shaft 5 are respectively connected to the two support shafts 3-1. A main support gear 7 is fixedly installed on the support shaft 5, and a secondary support gear 8 is fixedly installed on the support shaft 3-1. The main support gear 7 and the secondary support gear 8 are meshed with each other. The radius of the main support gear 7 is smaller than the radius of the secondary support gear 8. A support gear box 6 is fixedly installed on the mounting frame 2. A set of meshing main support gears 7 and secondary support gears 8 are set in a support gear box 6. The bottom plate of the support gear box 6 is fixedly installed on the frame 10. The support drive motor 3-4 is fixedly installed on the frame 10, and the output shaft of the support drive motor 3-4 is connected to the front end shaft of the right support drive shaft 5. A transmission shaft 9 is spun on the frame 10 through bearings, and the transmission shaft 9 is set between the left and right support drive shafts 5. The transmission shaft 9 and the support drive shaft 5 are connected by a bevel gear set.

[0043] The protective mechanism 4 includes a main pulley 4-1, auxiliary pulleys 4-3, and a protective net 4-5. The main pulleys 4-1 consist of two sets mounted on the front and rear mounting frames 2. One set of main pulleys 4-1 consists of two pulleys and is screwed onto the left end and middle of the frame 10 via a rotating shaft. The auxiliary pulleys 4-3 also consist of two sets mounted on the front and rear mounting frames 2. One set of auxiliary pulleys 4-3 consists of two pulleys and is screwed onto the right end and middle of the frame 10 via a rotating shaft. The main pulley 4-1 located in the middle of the mounting frame 2 is positioned alongside the two auxiliary pulleys 4-5. Between the two main pulleys 4-1, the auxiliary pulley 4-3 located in the middle of the mounting frame 2 is positioned between the two main pulleys 4-1. The radius of the main pulley 4-1 is larger than the radius of the auxiliary pulley 4-3. A protective drive motor 14 is fixedly mounted on the frame 10. A protective drive shaft 15 is fixedly mounted on the output shaft of the protective drive motor 14. The protective drive shaft 15 is screwed onto the mounting frames 2 on the front and rear sides via bearings. The main pulley 4-1 located on the left side of the mounting frame 2 is sleeved and fixed on the protective drive shaft 15. The main pulley 4-1 located in the middle of the mounting frame 2 is positioned between the two main pulleys 4-1. A main protective gear 11 is fixedly mounted on the shaft of pulley 4-1, and a secondary protective gear 12 is fixedly mounted on the shaft of the secondary pulley 4-3 located in the middle of the mounting frame 2. The main protective gear 11 and the secondary protective gear 12 are meshed with each other. The radius of the main pulley 4-1 is larger than the radius of the secondary pulley 4-3, and the radius of the main protective gear 11 is larger than the radius of the secondary protective gear 12. A protective gear box 13 is fixedly mounted on the mounting frame 2, and both the main protective gear 11 and the secondary protective gear 12 are housed within the protective gear box 13. The base plate of the gearbox 13 is fixedly mounted on the frame 10; a main stepping belt 4-2 is fitted on a set of two main pulleys 4-1, and a secondary stepping belt 4-4 is fitted on a set of two secondary pulleys 4-3. Two protective nets 4-5 are mounted on one side of the photovoltaic panel 1. The front and rear sides of one protective net 4-5 are fixedly mounted on the main stepping belts 4-2 on the front and rear sides, and the front and rear sides of the other protective net 4-5 are fixedly mounted on the secondary stepping belts 4-4 on the front and rear sides. The adjacent sides of the two protective nets 4-5 are staggered and overlapped.

[0044] When using this device, if the photovoltaic panel 1 needs to work normally, move the two protective nets 4-5 below the photovoltaic panel 1. The support drive motor 3-4 drives the right support drive shaft 5 to rotate, which in turn drives the left and right support drive shafts 5 to rotate synchronously through the transmission shaft 9. The support drive shaft 5 drives the support shaft 3-1 to rotate through the meshing main support gear 7 and secondary support gear 8. The support shaft 3-1 drives the support arm 3-2 to rotate and lift, and then the left and right support arms 3-2 cooperate to lift the photovoltaic panel 1 upward, so that the photovoltaic panel 1 is higher than the mounting frame 2 and the frame 10, so that the photovoltaic panel 1 can fully receive sunlight and work. When it is necessary to protect the photovoltaic panel 1, put the photovoltaic panel 1 down into the mounting frame 2, and place the photovoltaic panel 1 between the front and rear secondary pulleys 4-3, and place the photovoltaic panel 1 between the upper and lower surfaces of the secondary stepping belt 4-4. Then, the protective drive motor 14 drives the protective drive shaft 15 to rotate, which in turn drives the left main pulley 4-1 to rotate. The main stepping belt 4-2 drives the right main pulley 4-1 to rotate. Then, the meshing main protective gear 11 and auxiliary protective gear 12 drive the auxiliary pulley 4-3 to rotate, which in turn drives the auxiliary stepping belt 4-4 to rotate. The main stepping belt 4-2 and the auxiliary stepping belt 4-4 move in opposite directions. The main stepping belt 4-2 moves one protective net 4-5 from the left to the top of the photovoltaic panel 1, and the auxiliary stepping belt 4-4 moves one protective net 4-5 from the right to the top of the photovoltaic panel 1. The adjacent sides of the two protective nets 4-5 after being moved to the top are overlapped, so that the two protective nets 4-5 are erected on the top of the photovoltaic panel 1, thus protecting the surface of the photovoltaic panel 1.

[0045] Compared with the prior art, the beneficial effects of the present invention are:

[0046] 1. This device protects the photovoltaic panel 1 by installing two protective nets 4-5 to protect the surface of the photovoltaic panel 1. When the photovoltaic panel 1 needs to be used normally, the protective nets 4-5 are moved to the bottom of the photovoltaic panel 1 to achieve switching between the two working states of normal operation of the photovoltaic panel 1 and protection of the photovoltaic panel 1.

[0047] 2. This device uses a synchronous transmission support arm 3-2 to erect the photovoltaic panel 1, and a support drive motor 3-4 is set as a power source to raise the photovoltaic panel 1 or lower the photovoltaic panel 1 for protection.

[0048] 3. This device uses a main pulley 4-1 to support a main stepping belt 4-2, and a secondary pulley 4-3 to support a secondary stepping belt 4-4. The protective net 4-5 is then erected through the cooperation of the main stepping belts 4-2 and the secondary stepping belts 4-4 on both the front and rear sides. The transmission between the main pulleys 4-1 and the secondary pulleys 4-3 is achieved through the transmission of the main protective gear 11 and the secondary protective gear 12, thereby realizing the raising and lowering of the protective net 4-5 and thus achieving the protection and control of the photovoltaic panel 1.

[0049] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
