Description

Technical Field

[0001] This invention belongs to the field of photovoltaic technology, specifically relating to a BIPV photovoltaic sunroom. Background Technology

[0002] Due to various energy-saving requirements for buildings and the development needs of Building Integrated Photovoltaics (BIPV, where PV stands for Photovoltaic), more and more BIPV buildings are emerging. For family villas and public buildings such as shopping malls, office buildings, and residential buildings, there is an increasing need to convert them into BIPV sunrooms. A considerable portion of the demand involves adding balconies, terraces, or rooftops to BIPV sunrooms. However, the current design, production, and construction of BIPV sunrooms are inconvenient. Components need to be customized, and a large amount of on-site welding is required. This not only results in long construction cycles and welding safety hazards, but also makes it impossible to integrate doors and windows into a single unit.

[0003] Currently, the commonly used BIPV sunroom design involves on-site welding of all steel structural components, while the photovoltaic modules are custom-made laminated glass photovoltaic modules. Laminated glass photovoltaic modules often need to be customized, resulting in a long production cycle. On-site installation is commonly done by using silicone sealant, which makes later disassembly and maintenance difficult, and it is also difficult to integrate them with other components such as doors and windows. Summary of the Invention

[0004] The purpose of this invention is to overcome at least one defect in the prior art and to provide a BIPV photovoltaic sunroom.

[0083] When the push-pull type of Embodiment 1 is changed to the sliding type, the second photovoltaic module 7 is installed on the drainage trough 5 through the second connecting mechanism, so that the second photovoltaic module 7 is slidably connected to the seventh connecting member 14 fixed on the drainage trough 5.

[0084] See Figures 25 to 27 The second connecting mechanism includes a seventh connector 14 and a handle 16. The second photovoltaic module 7 has retaining pins 17 on both sides. The seventh connectors 14 are fixed to the drainage grooves 5 on both sides of the second photovoltaic module 7. The sidewalls of the seventh connectors 14 have grooves for sliding cooperation with the retaining pins 17. The retaining pins 17 on both sides of the second photovoltaic module 7 are respectively located within the grooves of the corresponding seventh connectors 14. The grooves of the seventh connectors 14 include a vertically extending groove section 141 and a first horizontally extending groove section 142 and a second horizontally extending groove section 143. The two horizontal slide sections 143, the first horizontal slide section 142 and the second horizontal slide section 143 are perpendicular to and connected to the vertical slide section 141. When the second photovoltaic module 7 is in the closed state, the retaining shafts 17 on both sides of the second photovoltaic module 7 are located in the first horizontal slide section 142 and the handle is in the locked state. When the second photovoltaic module 7 is in the open position, the retaining shafts 17 on both sides of the second photovoltaic module 7 are located in the second horizontal slide section 143. The second horizontal slide section 143 is provided with a retaining groove 144 for horizontally limiting the retaining shafts 17.

[0085] In this embodiment, the seventh connector 14 is installed on the drainage groove 5 by bolts 19 and self-tapping screws.

Then, the second photovoltaic module slides vertically in a plane. During the sliding process, a pull-back force is applied to the second photovoltaic module, so that after the retaining shaft 17 slides to a certain position, it automatically enters the second horizontal slide groove section 143 and moves inward horizontally along the second horizontal slide groove section 143. It is locked in the retaining groove 144 inside the slide groove by its own weight.

[0088] The other technical features of this embodiment are the same as those of Embodiment 1.

[0089] In one embodiment, the installation process of the present invention is as follows: First, drill holes in the concrete foundation 20 to install column anchor bolts 21. Then, fix the first connector 8 to the concrete ground (floor beam) through the column anchor bolts 21. Install rivet nuts 23 in the opening of the bushing 82 of the first connector 8, and then fit the column 1 onto the outside of the bushing 82 of the first connector 8, and then tighten it with bolts 19. When connecting beams and columns, fit the second connector 9 onto the top of the column 1, then fit the main beam 2 into the groove inside the second connector 9, and then connect the beam and column with through bolts 19. At the splicing point of the main beam 2 or other components, the third connector is pre-installed with rivet nuts 23, the two components to be spliced ​​are fitted onto the third connector, and fixed with bolts 19. The main beam 2 and purlin 3 are connected using a fourth connector, which is L-shaped. Several round holes are pre-drilled in the fourth connector. After the purlin 3 is placed in the corresponding position, the fourth connector clamps both sides and fixes the purlin 3 to the main beam 2 with self-tapping screws. The column 1 and wall purlin 4 are connected using a fifth connector, which is L-shaped. Several round holes are pre-drilled in the fifth connector. After the wall purlin 4 is placed in the corresponding position, the fifth connector clamps both sides and fixes the wall purlin 4 to the column 1 with self-tapping screws.

[0090] At the door and window installation location, after installing the drainage channel 5 and the surrounding ordinary first photovoltaic module 6, the sixth connector 13 is fixed to the drainage channel 5 with self-tapping screws, bolts 19, and wing nuts. Then, the hinge 15 is fixed to the sixth connector 13. The other side of the hinge 15 is connected to the openable second photovoltaic module 7 with self-tapping screws, so that the second photovoltaic module 7 can rotate around the hinge 15. The other side of the openable second photovoltaic module 7 is fitted with a screw-on handle with self-tapping screws. The openable second photovoltaic module 7 can be closed and opened by screwing on the handle. Of course, this second photovoltaic module 7 can also be replaced with a door or window.

[0091] When the push-pull type is changed to a sliding type, the sixth connector 13 is changed to the seventh connector 14. The seventh connector 14 is installed on both sides of the openable second photovoltaic module 7. The second photovoltaic module 7 is mounted on the side of the clip 17, which is clipped into the sliding groove of the seventh connector 14. The seventh connector 14 is installed on the adjacent ordinary first photovoltaic module 6 and drainage groove 5 by self-tapping screws. In this way, the push-pull opening method of the second photovoltaic module 7 can be changed to a sliding opening method.

[0092] All components of this invention are installed using fasteners such as bolts and self-tapping screws to form a unified BIPV sunroom. After measuring the site for the BIPV sunroom, the design can be carried out according to the site dimensions, and the length of the main components can be determined. After the materials and components are transported to the site, no welding is required; they can all be assembled using fasteners such as bolts and self-tapping screws, resulting in high construction efficiency and preventing component deformation due to excessive bolt torque. Photovoltaic modules can be installed on the top and sides of the overall structure.

[0093] This invention utilizes conventional framed photovoltaic modules, which are cheaper and have lower construction costs than laminated glass photovoltaic modules. Furthermore, this invention eliminates the need for welding on-site, making it suitable for construction in areas with restricted open flame conditions. This invention can also integrate photovoltaic modules with doors and windows, allowing a second photovoltaic module to directly replace doors and windows. When using a second photovoltaic module to replace doors, a sliding door design is preferred; however, non-photovoltaic modules can also be used, offering high compatibility. Both the photovoltaic modules and the overall structure are easy to disassemble, facilitating future maintenance and modifications. The main components of this invention (column 1, main beam 2, purlin 3, wall purlin 4) are all conventional rectangular steel pipes, making them easy to procure. During processing, only the component length needs to be determined for cutting, and a few holes need to be made in necessary areas before transporting them to the site for construction, making processing convenient.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
