Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic curtain wall technology, specifically, it relates to a novel angle-adjustable photovoltaic curtain wall. Background Technology

[0002] Building exterior photovoltaic (PV) curtain walls are high-tech systems that combine solar power generation with the building envelope. They use thin-film or crystalline silicon photovoltaic modules as the core unit of the building facade, typically fixed to the facade via mounting brackets. While fulfilling the traditional functions of curtain walls such as protection, insulation, and shading, this system can also generate electricity using solar energy, achieving building energy self-sufficiency and reducing carbon emissions, resulting in significant energy-saving and environmental benefits.

[0003] Currently, photovoltaic (PV) curtain walls on building exteriors have several shortcomings in practical applications: First, they generally lack effective PV panel angle adjustment mechanisms, and are mostly fixed installations. This makes it impossible to adaptively adjust the tilt angle of the PV panels according to different sunlight conditions (such as seasonal and temporal changes), resulting in suboptimal solar energy collection efficiency and affecting the synergy of power generation and thermal management. Second, those that do employ adjustment mechanisms tend to have complex structures, high installation and maintenance costs, and are difficult to widely adopt.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] This utility model provides a novel angle-adjustable photovoltaic curtain wall, aiming to solve the problems of existing photovoltaic curtain walls having an inability to adjust the angle or high adjustment costs, complex structures, and high costs.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A novel angle-adjustable photovoltaic curtain wall comprises three main parts: an installation mechanism, a curtain wall mechanism, and an adjustment mechanism. Specifically:

[0008] (i) The installation mechanism is used to fix the photovoltaic curtain wall as a whole onto the mounting brackets on the exterior wall of the building, and to achieve rapid assembly and disassembly. Its specific structure includes:

[0009] Mounting plate: As the main load-bearing component, it has positioning blocks at the lower ends of both sides and multiple mounting slots on both sides of the front.

[0010] Mounting bracket: It is snapped onto both sides of the mounting plate. A limiting slot is provided in the middle of the upper surface, a limiting block is provided in the middle of the lower surface, and mounting slots are provided at the rear ends of both sides. Multiple mounting blocks are installed in the mounting slots, and a positioning slot is provided at the lower end of one side wall of the mounting slot.

[0011] Base: Fixed to the rear end of the mounting bracket, used to connect to the external wall mounting bracket by bolts.

[0012] Moving handle: Located on the back of the mounting plate for easy handling and positioning.

[0013] The mounting plate and mounting bracket are quickly positioned and fixed by the engagement of the positioning blocks and positioning slots, and the cooperation between the mounting slots and mounting blocks. Vertical splicing is achieved between mounting brackets through the cooperation of limit blocks and limit slots.

[0014] (ii) The curtain wall mechanism is used to support the photovoltaic panels and realize the collection and conduction of light energy, including:

[0015] Storage base: Fixed to the center of the front of the mounting plate, with a storage slot at the front end.

[0016] Curtain wall panel: Hinged to the upper part of the inner wall of the storage groove, it can be unfolded outward. The front features tempered glass and photovoltaic panels, while the back is fixedly connected to trapezoidal blocks. The tempered glass provides light transmission protection, and the photovoltaic panels surround the tempered glass, combining light transmission and photovoltaic power generation.

[0017] Fixing groove: Located around the front of the curtain wall panel, used to fix the photovoltaic panel. The groove is equipped with a gasket for cushioning.

[0018] The wiring connection assembly includes a first wiring connection block disposed within the trapezoidal block connection groove, and a second wiring connection block disposed on the back of the mounting plate. The photovoltaic panel is connected to the first wiring connection block, and the second wiring connection block is electrically connected to the first wiring connection block, and connected to an external cable via a connector to conduct light energy to the energy storage device.

[0019] (iii) The adjustment mechanism is used to adjust the unfolding angle of the photovoltaic panel to optimize the light reception conditions of the photovoltaic panel, including:

[0020] Guide chute: located inside one side wall of the storage chute.

[0021] Guide slider: It is slidably connected in the guide groove and has a threaded hole in the vertical direction.

[0022] Support plate: The front end of the support plate is hinged to the curtain wall panel, and the rear end is hinged to the guide slider.

[0023] Adjustment block: Installed on the back of the mounting plate, the adjustment block has a slot, part of the guide slider is located in the guide groove, and the other part of the rear extension is located in the slot.

[0024] Threaded rod: It is screwed to the threaded hole of the guide slider. The two ends of the threaded rod extend from the upper and lower ends of the adjusting block and are rotatably connected to it. Since the guide slider slides in the guide groove, the guide slider can be driven to move by rotating the threaded rod.

[0025] Rotating block: Fixed to the upper and lower ends of the threaded rod, it is equipped with a connecting block and a hexagonal block. A connecting block is fixedly connected to the center of its upper surface, and a hexagonal block is fixedly connected to the center of the upper surface of the connecting block.

[0026] The reinforcing block is assembled from two semi-cylindrical modules connected by bolts and nuts. It connects the upper and lower threaded rods for synchronous rotation, locking between the two rotating blocks. A hexagonal slot is located at the center of its inner wall, with connecting slots at both the upper and lower ends. The hexagonal slot engages with a hexagonal locking block, and the connecting slots engage with a connecting locking block. The reinforcing block has a locking groove on its exterior for securing with bolts.

[0027] (iv) Installation and working principle:

[0028] (1) Fix the mounting bracket to the external wall mounting bracket using base bolts;

[0029] (2) Connect the mounting brackets in the same vertical column to the limit slots using limit blocks;

[0030] (3) Push the mounting plate into the mounting groove from the rear, so that the positioning block slides into the positioning slot, the mounting block is engaged in the mounting slot, and it is fixed with bolts;

[0031] (4) The reinforcing block is snapped between the upper and lower rotating blocks so that the hexagonal snap block and the hexagonal snap slot, and the connecting snap block and the connecting snap slot are engaged. After the reinforcing block is locked with bolts, the linkage of the threaded rods in the same row can be realized.

[0032] (5) Connect the first line connector block and the second line connector block, and make sure the connector is connected to the external cable.

[0033] (V) Work Process:

[0034] Rotate any threaded rod using a tool. A linkage mechanism causes threaded rods in the same row to rotate synchronously, driving the guide slider to move along the guide groove. The support plate then pushes the curtain wall panel outwards, adjusting the angle of sunlight reception. After the photovoltaic panel receives sunlight and generates electricity, the energy is conducted through the wiring block to the connector, and finally transmitted to the energy storage device.

[0035] (vi) Advantages and effects:

[0036] 1. Modular design: The mounting plate and mounting bracket adopt a splicing structure, which allows for quick installation and facilitates partial replacement and maintenance.

[0037] 2. Quick installation: Modular design, combined with snap-fit ​​and bolt connection methods, greatly improves installation efficiency.

[0038] 3. Adjustable angle: The simple adjustment mechanism can adjust the angle of the curtain wall panel, optimize the light energy collection efficiency, and reduce costs.

[0039] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0040] This invention allows for flexible adjustment of the curtain wall panel's unfolding angle through an adjustment mechanism. The tilt angle can be optimized according to different seasons and times of day, improving the photovoltaic panel's light-receiving efficiency and thus increasing power generation. Furthermore, the simple structural design, combined with reinforcing blocks for synchronized operation, simplifies operation, reduces costs, and facilitates widespread application.

[0041] This utility model embodiment achieves rapid installation, adjustable angle, convenient maintenance, high-efficiency power generation, and low cost of photovoltaic curtain walls through modular splicing structure, circuit connection, and linked angle adjustment mechanism, and has high practical value and promotion prospects.

[0060] Example 1

[0061] like Figures 1 to 8 As shown in the figure, the novel angle-adjustable photovoltaic curtain wall described in this embodiment mainly includes an installation mechanism 1, a curtain wall mechanism 2, and an adjustment mechanism 3. The curtain wall mechanism 2 is located on the front side of the installation mechanism 1, and the adjustment mechanism 3 is located on the rear side of the installation mechanism 1 and is linked with the curtain wall mechanism 2.

[0062] Mounting mechanism 1 includes mounting plate 101 and mounting bracket 104. Positioning blocks 102 are provided at the lower ends of the outer walls on both sides of the mounting plate 101, and multiple mounting slots 103 are provided on both sides of its front side. Each mounting slot 103 is a through hole. (See attached image) Figure 3-4 As shown. A handle 1011 is provided in the middle of the back of the mounting plate 101 to facilitate the handling and positioning by construction personnel.

[0063] Mounting brackets 104 are arranged in pairs and respectively snapped onto both sides of mounting plate 101. Each mounting bracket 104 has a limiting slot 106 in the center of its upper surface and a limiting block 107 in the center of its lower surface. By interlocking the limiting block 107 of one mounting bracket 104 with the limiting slot 106 of another mounting bracket 104, multiple mounting brackets 104 can be quickly assembled vertically. Mounting grooves 108 are provided at the rear ends of the outer walls on both sides of each mounting bracket 104. Multiple mounting blocks 109, which are adapted to the mounting slots 103, are provided on the inner front wall of each mounting groove 108. A positioning groove 1010, adapted to the positioning block 102, is provided at the lower end of the inner wall of one side of each mounting groove 108. During installation, the positioning block 102 is first aligned and slid into the positioning slot 1010 for initial positioning. Then, the mounting slot 103 is engaged with the mounting block 109, and finally, bolts and other fasteners are used for final fixation, achieving a quick and reliable connection between the mounting plate 101 and the mounting frame 104. A base 105 is also fixedly connected to the rear outer wall of the mounting frame 104, used to fix the entire mounting mechanism 1 to a pre-installed bracket on the building's exterior wall using bolts.

[0064] The curtain wall mechanism 2 includes a storage base 201 and a curtain wall panel 203. The storage base 201 is fixedly connected to the middle of the front outer wall of the mounting plate 101, and a storage groove 202 is provided on the front outer wall of the storage base 201. The curtain wall panel 203 is hinged to the upper end of the inner wall of the storage groove 202 via a hinge shaft, so that the curtain wall panel 203 can be unfolded outward relative to the storage base 201. A tempered glass 204 is provided in the middle of the front outer wall of the curtain wall panel 203, and a fixing groove 205 is provided around it. The photovoltaic panel 207 is embedded in the fixing groove 205, and several gaskets 206 are provided in the groove to buffer the connection.

[0065] The rear outer wall of the curtain wall panel 203 is provided with a trapezoidal block 208, and both sides of the rear outer wall of the trapezoidal block 208 are provided with connecting grooves 209. A first wiring connecting block 2010 is provided in the middle of the front inner wall of one of the connecting grooves 209, and the photovoltaic panel 207 is connected to the first wiring connecting block 2010. Correspondingly, a second wiring connecting block 2011 is provided on one side of the rear (back) outer wall of the mounting plate 101. After the curtain wall panel 203 is installed in place, the first wiring connecting block 2010 and the second wiring connecting block 2011 need to be electrically connected, which can be done using cables or connectors. Connectors 2012 are provided at the center of the upper and lower surfaces of the second wiring connecting block 2011 for connecting external cables, thereby transmitting the electrical energy generated by the photovoltaic panel 207 to the energy storage device.

[0066] The adjustment mechanism 3 is used to adjust the unfolding angle of the curtain wall panel 203. The adjustment mechanism 3 includes a guide groove 301 formed on one side of the inner wall of the rear end of the storage groove 202, a support plate 303, an adjustment block 304, and a threaded rod 305. A guide slider 302 is slidably connected in the guide groove 301. The front end of the support plate 303 is hinged to the curtain wall panel 203, and the rear end is hinged to the guide slider 302. The adjustment block 304 is installed on the back of the mounting plate 101. The adjustment block 304 has a slot. Part of the guide slider 302 is located in the guide groove 301, and the other part is located in the slot. The threaded rod 305 is threadedly engaged with the guide slider 302. Both the upper and lower ends of the threaded rod 305 are rotatably connected to the adjustment block 304 through bearings. Rotating blocks 306 are fixedly connected to the upper and lower ends of the outer wall of the threaded rod 305. Twisting the rotating blocks 306 can realize the rotation of the threaded rod 305.

[0067] To achieve synchronous angle adjustment of multiple curtain wall units in the same row, a reinforcing block 309 is engaged between two adjacent rotating blocks 306. A connecting block 307 is fixedly connected to the center of the upper surface of the rotating block 306, and a hexagonal block 308 is fixedly connected to the center of the upper surface of the connecting block 307. A hexagonal slot 3011 adapted to the hexagonal block 308 is formed at the center of the inner wall of the reinforcing block 309, and connecting slots 3012 adapted to the connecting block 307 are formed at the upper and lower ends of its inner wall. By engaging the connecting blocks 307 and hexagonal blocks 308 on the upper and lower rotating blocks 306 into the connecting slots 3012 and hexagonal slots 3011 of the reinforcing block 309 respectively, the upper and lower threaded rods 305 can be linked. The reinforcing block 309 is assembled from two semi-cylindrical modules, and a locking groove 3010 is formed in the middle of the outer wall of the reinforcing block 309. The connection is secured by bolts and nuts.

[0068] During installation, firstly, the mounting bracket 104 is fixed to a predetermined position on the building's exterior wall using the base 105, and vertical splicing is completed through the cooperation of the limiting block 107 and the limiting slot 106. Then, the mounting plate 101 is pushed into the mounting slot 108 of the mounting bracket 104 from the rear, and initial positioning and mechanical connection are completed through the cooperation of the positioning block 102 and the positioning slot 1010, and the mounting slot 103 and the mounting block 109, and then secured with bolts. Next, the adjacent rotating blocks 306 are connected by the reinforcing block 309, ensuring that the hexagonal block 308 and the connecting block 307 are engaged in place, and then locked with bolts.

[0069] After installation, use a wrench or other tools to rotate the bottom of any threaded rod 305 (the top can also be rotated, but it requires climbing and is not as convenient as the bottom). The linkage structure causes all threaded rods 305 in the same row to rotate synchronously. The rotation of the threaded rod 305 drives the guide slider 302 to move along the guide groove 301, which in turn pushes the curtain wall panel 203 to rotate around its hinge point through the support plate 303, adjusting it to different angles.

[0070] The electrical energy generated by the photovoltaic panel 207 is sequentially connected to the external cable through the first line connection block 2010, the second line connection block 2011 and the connector 2012, and finally delivered to the building's energy storage or power consumption system.

[0071] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
