Abstract
Description
Technical Field
[0001] This utility model relates to the field of flat-roof photovoltaic sheds, specifically to a BIPV flat-roof photovoltaic shed with built-in tooth type. Background Technology
[0002] Building-integrated photovoltaics (BIPV) is a technology that integrates solar power generation (photovoltaic) products into buildings. Existing BIPV flat-roof photovoltaic structures typically use multiple photovoltaic modules sealed and spliced together to form a unified planar photovoltaic array, achieving surface waterproofing. Each photovoltaic module is also sealed and spliced with corresponding locking blocks. These locking blocks often protrude from the photovoltaic panel surface, appearing obtrusive and unsightly. Furthermore, when using robotic waterless cleaning methods, dust can remain on the raised outer edges of the photovoltaic module splicing points, leading to dust accumulation and corrosion, and also hindering the movement of the cleaning robots. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a built-in toothed BIPV flat-roof photovoltaic canopy:
[0004] A BIPV (Build-in-Place) flat-roof photovoltaic canopy with built-in locking teeth includes an L-shaped support frame, an X-shaped support frame, a Y-shaped support frame, and a photovoltaic panel array. The photovoltaic panel array is composed of multiple photovoltaic module arrays. Each photovoltaic module includes a photovoltaic panel and a frame surrounding the photovoltaic panel. The L-shaped, Y-shaped, and X-shaped support frames are fixedly connected sequentially from bottom to top. The lower end of the L-shaped support frame is fixed relative to the ground. The X-shaped support frame consists of multiple evenly arranged X-shaped support beams. Each X-shaped support beam includes a main beam and locking tooth module assemblies disposed within the main beam. The locking tooth module assemblies include multiple... The main beam includes a series of locking tooth assemblies arranged along its length. The main beam comprises an integrally fixed base plate, a convex support tube, and two inclined support plates located on both sides of the convex support tube. The upper sides of the convex support tube are provided with shoulder grooves that form a locking support with the photovoltaic module frame. The convex support tube has a strip-shaped cavity extending along its length inside. Multiple locking tooth assemblies are installed sequentially in the strip-shaped cavity. The upper sides of the convex support tube are provided with slots that adapt to the locking tooth assemblies. The locking tooth assemblies pass through the slots and form a locking and abutting fit with the outer end face of the adjacent photovoltaic module.
[0005] Preferably, the tooth assembly includes a housing fixedly connected to the inner wall of the strip-shaped cavity. The housing has a sliding cavity with a communicating groove. The sliding cavity has two symmetrically sliding teeth. The opposite end faces of the two sliding teeth are provided with semi-circular grooves. The two semi-circular grooves form a conical groove that is larger at the top and smaller at the bottom. Limiting protrusions are provided on both sides of the opposite ends of the sliding teeth. The limiting protrusions and the limiting parts provided on the side of the housing form a limiting fit, thereby limiting the sliding stroke of the sliding teeth. The housing has a vertical through hole corresponding to the conical groove. The upper end of the convex support tube has an upper through hole corresponding to the vertical through hole. The upper through hole, the vertical through hole, and the conical groove form an insertion channel. A nail-shaped component is inserted into the insertion channel. When the nail-shaped component is installed in the insertion channel, the two sliding teeth are pushed apart by the abutment of the nail-shaped component. At this time, the outer end of the sliding tooth passes through the groove and forms a locking and abutting fit with the end face of the photovoltaic module. The locking tooth assembly features a symmetrical sliding tooth and tapered groove design, which, combined with the insertion of the nail-shaped component, enables rapid installation and fixation. During installation, simply inserting the nail-shaped component into the insertion channel drives the sliding teeth to open and automatically lock into place with the photovoltaic module end face, eliminating the need for complex tools or additional adjustments, significantly reducing installation difficulty and time costs. Simultaneously, the X-axis limiting component connects to the support frame via bolt fasteners, further simplifying the installation process and improving construction efficiency.
[0006] Preferably, the sliding tooth is made of elastic metal material, and the outer end of the sliding tooth is provided with a rough biting surface. The biting surface and the end face of the photovoltaic module form a locking and abutting fit. The biting surface is provided with a plurality of oblique convex teeth evenly arranged along the length direction of the X-axis support beam. The end face of the photovoltaic module is provided with oblique tooth grooves that form a locking and meshing fit with the oblique convex teeth.
[0007] Preferably, adjacent photovoltaic modules are limited by X-direction support beams or by direct abutment against each other. The oblique grooves and oblique convex teeth extend obliquely at an angle of 15°-30° relative to the length direction of the X-direction support beam, or form a V-shaped fish scale pattern. The 15°-30° oblique pattern forms a self-locking structure for the photovoltaic module itself. If the photovoltaic module needs to detach from the Y-direction support frame, it needs to move along the extension direction of the oblique pattern. If it moves obliquely upward, the adjacent photovoltaic modules exert a corresponding abutment force to limit its further outward movement. If it moves obliquely downward, the shoulder groove of the convex support tube provides corresponding support and limiting effect, preventing it from sliding further down. The V-shaped fish scale pattern structure has better self-locking performance, achieving its corresponding self-locking function without the need for adjacent photovoltaic modules, effectively preventing relative movement between the photovoltaic module and the X-direction support beam, but the structure is relatively complex.
[0008] Preferably, the X-direction support beam has two sets of locking tooth modules, with each locking tooth component in a corresponding vertical alignment. The teeth on the bite surfaces of each module are obliquely convex, and the extended lines of two adjacent bite surfaces form an angle of 30° to 90°. The bite surfaces of these modules mesh with the V-shaped fish-scale pattern of the oblique tooth grooves, creating a locking fit. The X-direction support beam has two sets of corresponding locking tooth modules, with the extended lines of their bite surfaces forming an angle of 30° to 90°, creating a cross-meshing with the V-shaped fish-scale grooves, enhancing the uniformity of the locking force distribution. This multi-directional locking design effectively prevents the components from sliding or tilting in the X and Y directions, improving wind pressure resistance and deformation resistance, making it suitable for harsh weather conditions.
[0009] Preferably, the upper end face of the convex support tube is provided with a countersunk groove corresponding to the upper through hole. The nail-type component includes an integral nail head and nail body. When the nail body is inserted into the insertion channel, the nail head matches the countersunk groove, and the upper end face of the nail head is flush with the upper end face of the convex support tube. The countersunk groove design of the nail-type component makes the nail head flush with the upper end face of the convex support tube, avoiding interference with cleaning operations. The nail-type component can be fixed by direct insertion or screwing in, providing flexible locking options and facilitating later maintenance or component replacement. In addition, the adjustable design of the oblique tooth groove pattern (such as angled or V-shaped) allows for selection of the self-locking method according to actual needs, enhancing the adaptability of the structure.
[0010] Preferably, the nail-shaped component and the insertion channel are fixed by direct insertion into the locking position or by screwing in the locking position.
[0011] Preferably, it further includes an X-direction limiting component disposed on the outer edge of the photovoltaic module. The X-direction limiting component includes a U-shaped outer edge plate and an L-shaped locking plate disposed within the U-shaped outer edge plate. The upper end of the U-shaped outer edge plate has an upper locking groove that matches the protruding frame on the back of the photovoltaic module. The bottom of the upper locking groove has multiple upper straight slot holes arranged along the length direction, which are perpendicular to the length direction of the U-shaped outer edge plate. The lower end of the L-shaped locking plate is fitted into the upper locking groove. The L-shaped locking plate and the inner sidewall of the upper locking groove form a locking and clamping mechanism for clamping and fixing the frame. The L-shaped positioning plate has multiple positioning holes arranged along its length. These positioning holes are adapted to the upper straight groove holes on the bottom surface of the upper slot. The positioning holes and the upper straight groove are fixedly connected by bolts. The upper end of the inclined support plate has a horizontal folding plate extending towards the convex support tube. The horizontal folding plate abuts against the lower end of the supporting U-shaped outer edge plate. The horizontal folding plate has a lower straight groove hole that is parallel to and adapted to the upper straight groove hole. Bolts corresponding to the lower straight groove hole pass through the positioning holes, the upper straight groove, and the lower straight groove hole for the fixed connection of the X-direction limiting component and the inclined support plate.
[0012] Preferably, the L-shaped support frame includes multiple parallel L-shaped support beams. Each L-shaped support beam includes a vertical support rod and an X-axis support rod. A gravity block is fixedly connected to the bottom of the vertical support rod, and multiple sequentially arranged wedge-shaped positioning blocks are fixedly connected to the upper end of the X-axis support rod. The wedge-shaped positioning blocks are fixedly connected to the Y-axis support frame, which is composed of multiple Y-axis support beams. The Y-axis support beams are channel steel structures and abut against the vertical plane of the wedge-shaped positioning blocks, forming a bolted connection with them. The Y-axis support beams are also bolted to the base plate of the main beam. The L-shaped support frame is fixed to the ground and the Y-axis support frame through the gravity block and wedge-shaped positioning blocks, and combined with the channel steel structure of the Y-axis support beams, it provides a solid foundation support. The integrated main beam design of the X-axis support beams enhances the load-bearing capacity and rigidity, ensuring that the photovoltaic canopy does not deform under long-term loads. The U-shaped outer edge plate and L-shaped locking plate of the X-direction limiting component are connected to the support frame by bolts, forming additional constraints and further ensuring the integrity and durability of the overall structure.
[0013] Beneficial effects: The photovoltaic canopy does not require the installation of corresponding locking blocks to connect each photovoltaic module. Instead, it uses hidden locking tooth components to lock and fix each photovoltaic module, which makes it easier to clean the surface of the photovoltaic canopy, facilitates installation, and improves the appearance.
[0014] 1. Concealing the structure and enhancing aesthetics:
[0015] This invention achieves concealed fixing of photovoltaic modules by embedding the toothed assembly within the strip-shaped cavity of the convex support tube and utilizing a nail-shaped component to activate the locking function of the sliding teeth. Compared to traditional exposed locking block structures, this design makes the photovoltaic canopy surface smoother and flatter, with no protruding parts. This not only improves the overall aesthetics but also prevents dust and debris accumulation, facilitating daily cleaning and maintenance. It is particularly suitable for BIPV applications where high aesthetic requirements apply.
[0016] 2. Self-locking mechanism and enhanced stability:
[0017] The serrated surfaces of the sliding teeth and the oblique grooves on the end face of the photovoltaic module employ a 15°-30° oblique pattern or a V-shaped fish scale pattern structure, forming an effective self-locking mechanism. This design makes it difficult for the photovoltaic module to move in the detachment direction when subjected to external forces (such as wind loads or vibrations): the oblique pattern requires the module to detach in a specific direction, while the abutment of adjacent modules and the support and limiting of the shoulder groove together constitute multiple layers of protection; the V-shaped fish scale pattern structure further enhances the self-locking performance, suppressing displacement without relying on adjacent modules, ensuring the robustness and stability of the photovoltaic module in long-term use.

[0031] The following is in conjunction with the appendix Figure 1-12 The present invention will be further described with reference to Examples 1-2.
[0032] Example: A BIPV flat-roof photovoltaic canopy with built-in locking teeth includes an L-shaped support frame, an X-axis support frame, a Y-axis support frame, photovoltaic panels, and an X-axis limiting component disposed on the outer edge of the photovoltaic modules. The photovoltaic panel assembly is composed of multiple photovoltaic modules arranged in an array, and each photovoltaic module includes a photovoltaic panel and a frame disposed around the photovoltaic panel. The L-shaped support frame, Y-axis support frame, and X-axis support frame are fixedly connected sequentially from bottom to top. The lower end of the L-shaped support frame is fixed relative to the ground, and the X-axis support frame is composed of multiple evenly arranged X-axis support beams. The L-shaped support frame includes multiple parallel L-shaped support beams. Each L-shaped support beam includes a vertical support rod and an X-axis support rod. A gravity block is fixedly connected to the bottom of the vertical support rod. Multiple wedge-shaped positioning blocks are fixedly connected to the upper end of the X-axis support rod. The wedge-shaped positioning blocks are fixedly connected to the Y-axis support frame. The Y-axis support frame is composed of multiple Y-axis support beams. The Y-axis support beams are channel steel structures. The Y-axis support beams abut against the vertical plane provided by the wedge-shaped positioning blocks and are bolted to them. The Y-axis support beams are bolted to the bottom plate of the main beam.
[0033] The X-axis support beam includes a main beam and a toothed module assembly disposed within the main beam. The toothed module assembly includes multiple toothed components sequentially disposed within the main beam along its length. The main beam includes an integrally fixed base plate, a convex support tube, and two inclined support plates located on either side of the convex support tube. The upper sides of the convex support tube are provided with shoulder grooves that form a locking support with the photovoltaic module frame. The interior of the convex support tube has a strip-shaped cavity extending along its length, in which multiple toothed components are sequentially installed. The upper sides of the convex support tube are provided with slots for adapting to the toothed components. The toothed components pass through the slots and engage with the outer end face of the adjacent photovoltaic module. The upper end face of the convex support tube has a countersunk groove corresponding to the upper through hole. The nail-shaped component includes an integral nail head and nail body. When the nail body is inserted into the insertion channel, the nail head is adapted to the countersunk groove, and the upper end face of the nail head is flush with the upper end face of the convex support tube. The nail-shaped component and the socket channel are fixed by direct insertion into the locking position or by screwing in the locking position.
[0034] The toothed assembly includes a housing fixedly connected to the inner wall of a strip-shaped cavity. The housing contains a sliding cavity with a communicating groove. Two symmetrically sliding teeth are located within the sliding cavity. Each of the two sliding teeth has a semi-circular groove on its opposite end face, forming a tapered groove that is larger at the top and smaller at the bottom. Limiting protrusions are located on both sides of the opposite ends of the sliding teeth. These limiting protrusions, together with limiting portions on the side of the housing, constitute a limiting fit, thereby limiting the sliding stroke of the sliding teeth. The housing has a vertical through hole corresponding to the tapered groove. The upper end of the convex support tube has an upper through hole corresponding to the vertical through hole. The upper through hole, the vertical through hole, and the tapered groove form an insertion channel. A nail-shaped component is inserted into the insertion channel. When the nail-shaped component is installed in the insertion channel, the two sliding teeth are pushed apart by the abutment of the nail-shaped component. At this time, the outer end of the sliding tooth passes through the groove and forms a locking and abutting fit with the end face of the photovoltaic module.
[0035] The X-direction support beam has two sets of toothed module groups. The toothed components of different toothed module groups are matched one-to-one, with the bite surface teeth of each module group having an oblique convex tooth structure and the extended lines of two adjacent bite surfaces forming an angle of 30° to 90°. The bite surface teeth of different toothed module groups and the V-shaped fish-scale pattern oblique tooth grooves form a meshing and locking fit. The sliding teeth are made of elastic metal, and the outer end of the sliding teeth has a rough bite surface. The bite surface and the end face of the photovoltaic module form a locking and abutting fit. The bite surface has multiple oblique convex teeth evenly arranged along the length of the X-direction support beam. The end face of the photovoltaic module has oblique tooth grooves that mesh with the oblique convex teeth.
[0036] The X-direction limiting component includes a U-shaped outer edge plate and an L-shaped locking plate disposed within the U-shaped outer edge plate. The upper end of the U-shaped outer edge plate has an upper locking groove that matches the protruding frame on the back of the photovoltaic module. The bottom of the upper locking groove has multiple upper straight slots arranged along its length, perpendicular to the length direction of the U-shaped outer edge plate. The lower end of the L-shaped locking plate is fitted into the upper locking groove. The L-shaped locking plate and the inner wall of the upper locking groove form a locking and clamping mechanism for clamping and fixing the frame. The L-shaped locking plate has a [missing information - likely a feature or design]. Multiple positioning holes are arranged along the length direction. The positioning holes are adapted to the upper straight groove holes provided on the bottom surface of the upper slot. The positioning holes and the upper straight groove are fixedly connected by bolts and fasteners. The upper end of the inclined support plate is provided with a horizontal folding plate extending towards the convex support tube. The horizontal folding plate abuts against the lower end of the supporting U-shaped outer edge plate. The horizontal folding plate is provided with a lower straight groove hole that is parallel to and adapted to the upper straight groove hole. The bolts and fasteners corresponding to the lower straight groove hole pass through the positioning holes, the upper straight groove, and the lower straight groove hole for the fixed connection of the X-direction limiting component and the inclined support plate.
[0037] Example 2: The difference between Example 2 and Example 1 is that there is only one set of toothed module group installed in the main beam. Adjacent photovoltaic modules are limited by the X-direction support beam or by directly abutting each other. The texture of the oblique tooth groove and oblique convex tooth extends obliquely at an angle of 15°-30° relative to the length direction of the X-direction support beam or has a V-shaped fish scale pattern.
[0038] Operating principle: First, the L-shaped support frame, Y-axis support frame, and X-axis support frame are sequentially fixed and connected to form the main load-bearing frame. The shoulder groove at the top of the X-axis support beam provides an initial positioning and bearing platform for the photovoltaic modules. During installation, the photovoltaic modules are placed directly on the shoulder groove to complete the initial positioning. Then, the locking process begins—by vertically inserting the nail-shaped parts into the insertion channels above the support beam, the conical nail body of the nail-shaped parts opens the built-in symmetrical sliding teeth, driving them to slide outwards, so that the biting surfaces at their ends tightly abut against and embed into the oblique tooth grooves on the sidewalls of the adjacent photovoltaic modules, forming a lateral locking force.
[0039] The serrated surface and the oblique grooves, or the V-shaped fish-scale pattern, constitute a mechanical self-locking mechanism. This design restricts the direction of photovoltaic modules' detachment under external force by the oblique groove direction, while the mutual abutment of adjacent modules and the support of the shoulder grooves create multi-dimensional constraints. At the array edges, X-axis limiting components are connected to the support frame via bolts, providing additional clamping and anchoring for the outermost photovoltaic modules. This series of synergistic actions connects the individual photovoltaic units into a rigid, integrated roof. The system achieves a balance between rapid assembly and reliability, with all fastening components hidden from view, forming a simple, wind-resistant, and easy-to-maintain building-integrated photovoltaic (BIPV) roof system.
[0040] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
