Description

Technical Field

[0001] This invention belongs to the field of building-integrated photovoltaics (BIPV) technology, and in particular relates to an integrated device for building waterproofing projects using photovoltaics. Background Technology

[0002] Building-integrated photovoltaics (BIPV) is a technology that integrates solar photovoltaic (PV) products into buildings. BIPV differs from the traditional method of attaching PV systems to buildings. BIPV can be divided into two main categories: one is the combination of PV arrays with buildings, and the other is the integration of PV arrays with buildings, such as photovoltaic tile roofs, photovoltaic curtain walls, and photovoltaic skylights. Of these two methods, the combination of PV arrays with buildings, especially with building roofs, is a common approach.

[0003] Currently available integrated building waterproofing devices for photovoltaic systems suffer from structural instability, making them susceptible to structural damage from wind and rain. This leads to loosening of the structure and poor waterproofing performance, resulting in leaks in the integrated photovoltaic system.

[0004] Therefore, we propose an integrated building waterproofing system for photovoltaic applications to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing an integrated building waterproofing device for photovoltaic applications.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated building waterproofing device for photovoltaic applications, comprising two adjacent photovoltaic panels, each photovoltaic panel having a support leg fixedly connected to its four bottom corners, a base plate fixedly connected to the lower end of each support leg, a common sealing block between the two photovoltaic panels, a base plate fixedly connected to the lower end of the sealing block, an L-shaped connecting rod fixedly connected to each of the four bottom corners of the base plate, a first U-shaped locking plate fixedly connected to the lower end of each L-shaped connecting rod and pressed against the support leg, and a second U-shaped locking plate fixedly connected to the side wall of the first U-shaped locking plate and pressed against the other side of the support leg;

[0007] The photovoltaic panel has two side plates symmetrically fixedly connected to both its front and back sides. Two guide rods are fixedly connected between the two side plates. The same U-shaped upright plate is slidably sleeved around the four guide rods. Multiple fixing rods are fixedly connected to the lower horizontal part of the U-shaped upright plate. The lower ends of the multiple fixing rods are slidably connected to the same scraper. The upper end of the scraper has multiple cylindrical grooves that are inserted and sleeved with the fixing rods. The same compensating spring is fixedly connected between the lower end of the fixing rod and the bottom of the cylindrical groove. A moving mechanism is installed between the U-shaped upright plate and the photovoltaic panel.

[0008] In the aforementioned integrated building waterproofing device for photovoltaic applications, multiple sealing plugs are fixedly connected to both opposite sides of the sealing block, and multiple sealing plug grooves that match and plug into the sealing plugs are opened on the outer side of the photovoltaic panel.

[0009] In the aforementioned integrated building waterproofing device for photovoltaic applications, a plurality of T-shaped clips are fixedly connected to one side of the lower end of the photovoltaic panel, and a plurality of T-shaped slots that match and engage with the T-shaped clips are provided on the upper side wall of the base plate.

[0010] In the aforementioned integrated photovoltaic building waterproofing device, two wedge-shaped locking blocks are symmetrically fixedly connected to the outer ends of both the first and second U-shaped locking plates. The same positioning block is locked to the two wedge-shaped locking blocks on opposite sides. The side wall of the positioning block has two dovetail grooves that match and lock to the wedge-shaped locking blocks. Multiple insertion holes are provided on both sides of the positioning block, and locking rods are movably inserted into the corresponding insertion holes. Multiple locking grooves that match and lock to the locking rods are provided on the outer sides of both the first and second U-shaped locking plates. The outer ends of multiple locking rods on the same side are fixedly connected to the same locking pull plate. Multiple locking springs, each sleeved on the outside of the multiple locking rods, are fixedly connected between the locking pull plate and the positioning block.

[0011] In the aforementioned integrated photovoltaic building waterproofing device, the upper outer side of the support leg is fixedly sleeved with a top baffle that abuts against the upper end of the first U-shaped clamping plate and the second U-shaped clamping plate.

[0012] In the aforementioned integrated photovoltaic building waterproofing device, multiple triangular reinforcing plates are symmetrically fixed at the connection between the first U-shaped clamping plate and the L-shaped connecting rod.

[0013] In the aforementioned integrated photovoltaic building waterproofing device, the moving mechanism includes a dual-axis motor fixedly connected to the upper end of a U-shaped upright plate. Both output ends of the dual-axis motor are fixedly connected to a drive shaft. Both outer ends of the U-shaped upright plate are connected to gears via rotating shafts. The lower outer end of the photovoltaic panel is fixedly connected to the same rack that meshes with the gears via multiple L-shaped support rods. One end of the drive shaft is connected to the rotating shaft via a pulley assembly.

[0014] In the aforementioned integrated photovoltaic building waterproofing device, two bearing seats are symmetrically fixedly connected to the upper end of the U-shaped vertical plate. The inner wall of the bearing seat is rotatably sleeved on the outer wall of the drive shaft at the end away from the dual-shaft motor via ball bearings.

[0015] Compared with the prior art, the present invention provides an integrated device for building waterproofing in photovoltaic applications, which has the following advantages:

[0016] 1. This integrated building waterproofing device for photovoltaic applications utilizes photovoltaic panels. The connection between two photovoltaic panels is achieved through the matching insertion of sealing plugs and sealing grooves, resulting in a stable sealing connection between the sealing plug and the two photovoltaic panels. At this point, a base plate supports the lower ends of the two photovoltaic panels. A stable connection between the photovoltaic panels and the base plate is achieved through the matching engagement of multiple T-shaped clips and T-shaped slots. The lower end of the base plate is then fixed to the outside of the support leg by an L-shaped connecting rod, and a second U-shaped clamping plate is pressed onto the other side of the support leg, providing support. On the outer side of the first U-shaped locking plate, the wedge-shaped locking block and the dovetail locking groove match and engage, allowing the positioning block to connect the first U-shaped locking plate and the second U-shaped locking plate together. After connection, the locking rod aligns with the locking groove, the locking spring pulls back the locking plate, and the locking plate pushes the locking rod into the locking groove, achieving a stable locking and fixing of the positioning block. This ensures a stable connection between the first U-shaped locking plate and the second U-shaped locking plate, allowing two adjacent photovoltaic panels to be stably connected together. The connection also has excellent sealing and waterproof protection performance, improving the strength of use and providing good waterproof protection.

[0017] 2. This integrated building waterproofing device for photovoltaic applications uses a U-shaped vertical plate. When the surface of the photovoltaic panel needs cleaning, a dual-axis motor is activated, driving two transmission shafts to rotate synchronously. This rotation is then achieved through a pulley assembly, which in turn drives the rotating shaft and gears. The meshing of the gears and racks, along with the guide slide rod, moves the U-shaped vertical plate, allowing the scraper to effectively clean the surface of the photovoltaic panel. The U-shaped vertical plate is connected to the scraper via a fixed rod and a cylindrical groove. The compensating spring ensures that the scraper remains in contact with the surface of the photovoltaic panel, guaranteeing cleaning quality and efficiency.

[0018] In summary, this invention enables two adjacent photovoltaic panels to be stably connected together, and the connection has excellent sealing and waterproof protection performance, improving the strength of use and providing good waterproof protection. Attached Figure Description

The same positioning block 21 is locked to the two wedge-shaped locking blocks 20 on the left and right. The side wall of the positioning block 21 has two dovetail grooves 22 that match and lock with the wedge-shaped locking blocks 20. Multiple insertion holes are opened on both ends of the side wall of the positioning block 21, and locking rods 23 are movably inserted into the corresponding insertion holes.

[0034] The operating principle of the present invention is described as follows: Through the provided photovoltaic panels 1, the connection between the two photovoltaic panels 1 is achieved by the matching insertion of sealing plug 4 and the two photovoltaic panels 1 through sealing plug 16 and sealing plug groove 17. At this time, the bottom support plate 5 supports the lower ends of the two photovoltaic panels 1. The photovoltaic panels 1 and the bottom support plate 5 are stably connected by the matching snap-fit ​​of multiple T-shaped clips 18 and T-shaped slots 19.

The connection provides excellent sealing and waterproof protection, improving durability and waterproofing. When cleaning is required on the surface of the photovoltaic panel 1, the dual-axis motor 28 is activated via the U-shaped upright plate 11. The dual-axis motor 28 drives two transmission shafts 29 to rotate synchronously, which in turn drives the rotating shaft and gear 30 through the transmission connection of the pulley assembly 33. The meshing of the gear 30 and rack 32, in conjunction with the guide slide rod 10, moves the U-shaped upright plate 11, enabling the scraper plate 13 to effectively wipe and clean the surface of the photovoltaic panel 1. The U-shaped upright plate 11 is connected to the scraper plate 13 via the insertion of the fixing rod 12 and the cylindrical groove 14. The compensation spring 15 ensures that the scraper plate 13 remains in contact with the surface of the photovoltaic panel 1, guaranteeing cleaning quality and efficiency.
