[0022] An implementable method discovered in the art—a building-integrated photovoltaic waterproof roof—includes a support frame, solar panels, slide rails, tarpaulin pulling devices, tarpaulin storage devices, and a top plate. Multiple solar panels are fixedly connected at equal intervals on the upper front of the support frame. Two slide rails are respectively opened on both sides of the upper part of the support frame. Two tarpaulin pulling devices are slidably connected in the two slide rails. The tarpaulin storage devices are fixedly connected to the rear of the support frame. The top plate is fixedly connected to the top of the support frame.

[0023] The tarpaulin traction device includes a traction trolley, tarpaulin clamps, fixing bolts, a control board, a control line, and a trolley motor. Two tarpaulin clamps are fixedly connected to the center of the back and the top of the traction trolley, respectively. The fixing bolts are slidably connected between the two tarpaulin clamps. The control board is fixedly connected to the top of the front end of the traction trolley. The control line is fixedly connected to the bottom of the control board. The trolley motor is fixedly connected to the end of the control line.

[0024] The rain cover storage device includes a storage tube, a top outlet, a roller fixing plate, a roller, a rainproof cloth, and a roller motor. The storage tube has a top outlet at the top. The roller fixing plate is fixedly connected to the right side of the storage tube. The roller is connected between the inner side of the roller fixing plate and the roller motor. The rainproof cloth is fixedly connected to the outer side of the roller. The roller motor is fixedly connected to the left side of the roller.

[0025] Working principle: When it rains, the rain cover traction device and rain cover storage device are activated. The traction trolley pulls the rain cover diagonally downward along the slide. The roller motor of the storage device works in conjunction to cover the top of the solar panel with the rain cover to prevent rainwater from corroding the surface. After the rain ends, the rain cover storage device is activated again, and the roller gradually retracts the rain cover to its original position, completing the use of the device.

[0026] An implementable method discovered in this field—a waterproof building-integrated photovoltaic (BIPV) device—includes a first support beam. The first support beam is evenly spaced, and two U-shaped plates are slidably connected inside the first support beam. A photovoltaic panel is mounted on the top of each U-shaped plate. A pressure plate is mounted on the top of the first support beam, and fixing plates are mounted on both sides of the pressure plate. The bottom of the fixing plates is attached to the top of the photovoltaic panels. A screw is installed inside the first support beam, with its top penetrating the bottom of the pressure plate. A pressure block is threadedly connected to the outer wall of the screw, and its bottom is attached to the top of the pressure plate. Sealing strips are provided on the top and bottom of the photovoltaic panels, and connecting plates are provided on opposite sides of the two sealing strips. Because the pressure block is threadedly connected to the screw, when the screw is rotated, the pressure block slides upward on the outer wall of the screw, creating a gap between the pressure block and the pressure plate, thus pulling the pressure plate. The photovoltaic panel moves upward in the gap, creating a gap between the pressure plate and the first support beam. The photovoltaic panel is then fixed to the top of the two U-shaped plates. One photovoltaic panel and two U-shaped plates form a splicing structure, and there are multiple splicing structures. Two sealing strips and connecting plates form an I-shaped sealing structure, which is fixed to one side of the photovoltaic panel. The multiple splicing structures are slidably connected to the two first support beams. The tops of the two U-shaped plates of the splicing structure slide into the gap between the pressure plate and the first support beam. When multiple photovoltaic panels are spliced, two adjacent photovoltaic panels are respectively attached to the side wall of the connecting plate, so that the sealing strip seals the connection between the two photovoltaic panels. After the photovoltaic panels are spliced, the screw is rotated in the opposite direction to drive the pressure block and pressure plate to move downward. The pressure plate drives the fixing plate to attach to the top of the photovoltaic panel, thereby clamping and fixing the photovoltaic panel.

[0027] The top of the pressure plate has a through groove, and one end of the screw passes through the inside of the through groove. The screw slides inside the through groove, thereby adjusting the position of the screw and the pressure block, so that the pressure block can squeeze different positions of the pressure plate.

[0028] The first support beam has a groove inside, and a bearing is installed inside the groove. One end of the screw is fixedly connected to the inner ring of the bearing. The groove limits the bearing, so that the bearing can only slide laterally inside the groove. When the screw slides inside the groove, the screw drives the bearing to slide inside the groove, thus limiting and guiding the screw. Rainwater enters the interior of the first support beam through the groove and is drained through the first support beam. A spring is installed between the top of the bearing and the bottom of the pressure plate. When the pressure plate moves away from the first support beam, the spring force pushes the pressure plate to move upward, thus exposing the gap between the pressure plate and the first support beam to the outside, which facilitates the installation of U-shaped plates and photovoltaic panels by workers.

[0029] Both sides of the sealing strip are fixedly connected to trapezoidal plates. One side of the trapezoidal plate is attached to one side of the photovoltaic panel. When the two sealing strips are attached to the top and bottom of the photovoltaic panel respectively, the two sealing strips drive the trapezoidal plate to be attached to the surface of the photovoltaic panel. Rainwater can flow according to the tilt angle of the inclined surface of the trapezoidal plate, avoiding the accumulation and residue of rainwater at the contact position between the sealing strip and the photovoltaic panel.

[0030] The bottom of the first support beam is uniformly fixedly connected to the second support beam, and multiple second support beams are spliced ​​together by multiple first support beams, thereby improving the stability of the device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1-4 As shown, this embodiment provides a waterproof building-integrated photovoltaic device, including a box body 1. A winding assembly is installed inside the box body 1 for winding a waterproof cloth 17. An opening is provided on the side wall of the box body 1, through which the waterproof cloth 17 passes and extends out of the box body 1. Arc-shaped plates 2 are symmetrically fixed to both sides of the box body 1. A sliding assembly is installed inside the arc-shaped plates 2 and is fixed to the waterproof cloth 17. A water tank 8 is fixed to the bottom of the arc-shaped plates 2. A support 5 is provided on one side of the water tank 8, and a photovoltaic panel 4 is installed on the support 5. The photovoltaic panel 4 is located below the box body 1.

[0034] In use, the sliding component moves within the curved plate 2, causing the waterproof cloth 17 to move. The waterproof cloth 17 is continuously unrolled by the retracting component, thus covering the photovoltaic panel 4 below, providing rain protection without completely obstructing the photovoltaic panel 4, allowing it to continue operating and improving work efficiency. Rainwater flows down the waterproof cloth 17 into the water tank 8 for storage. When not in use, the sliding component moves in the reverse direction, and the retracting component retracts the waterproof cloth 17, ensuring no sunlight is blocked. This design is convenient and quick to use. This utility model has a simple structure, is easy to use, and can provide rain protection without affecting the normal operation of the photovoltaic panel 4. It is highly efficient and practical.

[0035] The design is further optimized by including a rewind assembly comprising a roller 16 rotatably connected to the inner wall of the housing 1. The end of the waterproof fabric 17 is fixedly connected to and wound around the roller 16. Torsion springs 18 are installed at both ends of the roller 16, with one end of each spring fixedly connected to the roller 16 and the other end fixedly connected to the inner wall of the housing 1. During use, the sliding assembly moves the waterproof fabric 17, causing the roller 16 to rotate and the waterproof fabric 17 to unfold continuously. When not in use, the sliding assembly moves in the opposite direction, causing the roller 16 to rotate in the opposite direction under the action of the torsion springs 18, thus rewinding the waterproof fabric 17. This design is convenient to use.

[0036] A further optimized design includes a sliding component comprising a toothed plate 10 fixedly connected to the inner wall of the arc-shaped plate 2. The toothed plate 10 meshes with a gear 14. A stepper motor 13 is fixedly connected to one side of the gear 14, and a connecting block 15 is rotatably connected to the other side of the gear 14. The connecting block 15 is fixedly connected to a waterproof cloth 17. The stepper motor 13 drives the gear 14 to rotate, causing the gear 14 to move around the toothed plate 10. The gear 14 then drives the connecting block 15 to move, which in turn drives the waterproof cloth 17 to move, thereby covering the photovoltaic panel 4 below and providing a waterproof function.

[0037] In a further optimized design, a slide rail 11 is fixedly connected to the inner wall of the arc-shaped plate 2, and a sliding sleeve 12 is slidably connected to the slide rail 11. The outer wall of the sliding sleeve 12 is fixedly connected to the stepper motor 13. The arrangement of the slide rail 11 and the sliding sleeve 12 facilitates the movement of the stepper motor 13 and ensures the stability of the transmission process.

[0038] To further optimize the design, a groove 3 is provided on the curved plate 2, and the connecting block 15 is located within the groove 3 and slidably connected to it. The groove 3 limits the movement of the connecting block 15, ensuring greater stability during the movement process.

[0039] The design is further optimized by incorporating several connecting pipes 19 fixedly connected and arranged within the water tank 8 at an angle. Several water tanks 9 are installed on the outside of the water tank 8, with each water tank 9 corresponding to a specific connecting pipe 19. Rainwater flows through the water tank 8 and the connecting pipes 19 into the water tanks 9 for storage, thus improving resource utilization.

[0040] Further optimization of the design involves symmetrically fixing counterweights 6 to the side walls of the water tank 8. The counterweights 6 ensure the stability of the curved plate 2.

[0041] To further optimize the design, a pair of support rods 7 are fixedly connected to both sides of the support 5, and the support rods 7 are fixedly connected to the counterweight 6. The support rods 7 connect the counterweight 6 and the support 5, making the structure more stable.
