Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic technology, specifically to a modular building-integrated solar photovoltaic power generation device. Background Technology

[0002] Prefabricated building-integrated solar photovoltaic (PV) power generation devices are a green energy solution that deeply integrates PV power generation systems with modular building structures, featuring rapid deployment, high-efficiency power generation, and building integration.

[0003] Patent CN222356277U relates to an assembled building-integrated solar photovoltaic power generation device, belonging to the field of solar photovoltaics. It includes a main support rod with a horizontal groove on its top surface and symmetrical side mounting holes on its sides. Sealing end plates are connected to both ends of the main support rod, and fixing screws are symmetrically inserted into the sides of the sealing end plates. A main support plate is horizontally connected to the top surface of the main support rod, and a solar panel is horizontally fixed to the top surface of the main support plate. A bottom connecting rod is vertically connected to the bottom surface of the main support rod, and a bottom sleeve rod is vertically sleeved at the bottom end of the bottom connecting rod. Limiting through holes are symmetrically opened on the sides of the bottom sleeve rod, and a mounting base plate is horizontally welded to the bottom end of the bottom sleeve rod. This patent employs a snap-fit ​​connection structure, making the modular structure more convenient and efficient to assemble, while the adjustable structure allows it to meet installation and use in various environments.

[0004] The aforementioned patent improves assembly efficiency by using a snap-fit ​​connection structure, which allows installers to quickly assemble the photovoltaic panel bracket. However, when fixing the photovoltaic panel, the installer needs to place the photovoltaic panel on the inclined surface of the bracket and fix it by screwing in screws. Since the photovoltaic panel needs to be adjusted multiple times during fixing, especially when placed on an inclined surface, the photovoltaic panel may shift, thus affecting the accuracy of the installation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a modular building-integrated solar photovoltaic power generation device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an assembled building-integrated solar photovoltaic power generation device, comprising a ground joist and photovoltaic panels, wherein the ground joist is fixed to the ground and includes: a support frame, the support frame being fixedly installed on the top of the ground joist, the support frame having a through hole; a lifting frame, the lifting frame being slidably installed inside the support frame; a mounting frame, the mounting frame being rotatably inserted through the inner and outer walls of the lifting frame, the top of the mounting frame having an internally threaded blind hole for installing the photovoltaic panel, screws being screwed into the surface of the photovoltaic panel to gradually tighten the screws and fix the photovoltaic panel and the mounting frame; a movable frame, the movable frame being slidably installed on the top of the ground joist, the movable frame being rotatably connected to the end of the mounting frame away from the lifting frame; a handle, the handle being slidably inserted through the inner and outer walls of the lifting frame; a first spring, the first spring being disposed between the handle and the lifting frame, the handle being manually pulled outwards to move and stretch the first spring; and a fixing block, the fixing block being fixedly installed on the top of the lifting frame, the fixing block having an internally threaded through hole.

[0007] According to the above technical solution, a mounting plate is fixedly installed on the outer wall of the support frame, a limit block is fixedly installed on the side of the mounting plate near the ground keel, and a rubber plate is fixedly installed on the inner wall of the mounting plate. When the grip rod moves, it contacts the rubber plate, and the rubber plate forms frictional resistance through elastic deformation.

[0008] According to the above technical solution, the bottom of the limiting block is provided with a lower groove, the top of the rubber plate is provided with an upper groove, and the circumferential surface of the grip rod contacts the lower groove. The grip rod, which is limited, maintains the stability of the lifting frame and reduces the shaking of the mounting frame when the screws are tightened.

[0009] According to the above technical solution, the support frame is equipped with a protective device to improve the safety of angle adjustment, and the protective device is equipped with an auxiliary device to improve the flexibility of angle adjustment. The protective device includes a rectangular plate, a sliding seat, a rotating plate, a contact plate, and a handle. The handle moves upward and contacts the bottom of the rotating plate, and continues to move upward to apply a vertical thrust to the rotating plate. The rectangular plate is fixedly installed on the outer wall of the support frame, the sliding seat is slidably installed on the inner wall of the rectangular plate, the rotating plate is rotatably installed on the inner wall of the sliding seat, the contact plate is fixedly installed on the inner wall of the rectangular plate, and the handle is fixedly installed on the bottom of the sliding seat. The bottom of the rectangular plate has a movable groove, and the circumferential surface of the handle contacts the movable groove. The top of the rotating plate has an arc-shaped groove, and the handle moves and contacts the arc-shaped groove. The rotating plate, supported by the contact plate, applies a blocking force to the handle, preventing the handle from moving downward.

[0010] According to the above technical solution, a rectangular groove is provided on the top of the rectangular plate, and a round rod slides through the rectangular groove. A round plate is fixedly installed on the circumference of the round rod. A second spring is provided between the round plate and the rectangular plate. When the sliding seat moves, it drives the round rod to move synchronously. The round rod squeezes the second spring. When the handle is released, the second spring returns to its original position and pushes the round rod back to its original position.

[0011] According to the above technical solution, a linkage block is fixedly installed on the circumferential surface of the round rod, and a first torsion spring is provided between the rotating plate and the sliding seat. The first torsion spring is used for the rotating plate to rotate and reset, the rotating plate to rotate and disengage from the contact plate, and the first torsion spring is stretched during rotation.

[0012] According to the above technical solution, the auxiliary device includes a fixed frame, a rotating shaft, an elastic plate, and a T-shaped block. The linkage block moves and contacts the elastic plate, pushing the elastic plate to rotate. The fixed frame is fixedly installed on the top of the rectangular plate. The rotating shaft rotates through the inner wall of the fixed frame. The elastic plate is fixedly installed on the circumferential surface of the rotating shaft. The T-shaped block is fixedly installed on the inner wall of the fixed frame. A second torsion spring is provided between the rotating shaft and the fixed frame. The rotation of the rotating shaft stretches the second torsion spring. When the linkage block disengages from the elastic plate, the second torsion spring returns to its original position, causing the rotating shaft to rotate back. The T-shaped block and the side of the elastic plate closest to the support frame then contact each other.

[0013] According to the above technical solution, the inner wall of the fixed frame is provided with a moving groove, a lifting rod is slidably installed in the moving groove, a C-shaped frame is fixedly installed on the circumferential surface of the lifting rod, and a rectangular block is fixedly installed at the bottom of the C-shaped frame. When the C-shaped frame is pulled upward, the C-shaped frame moves and drives the lifting rod and the rectangular block to rise synchronously.

[0014] This invention provides a modular, building-integrated solar photovoltaic power generation device. It has the following beneficial effects: (1) The prefabricated building integrates a solar photovoltaic power generation device. The rubber plate and the grip are in close contact, which improves the stability of the grip. By stabilizing the grip, the installer is allowed to temporarily release the grip to perform other operations during the angle adjustment process, ensuring the continuity of the photovoltaic panel installation process. At the same time, the grip, which is limited, maintains the stability of the lifting frame. By stabilizing the mounting frame, the photovoltaic panel can be installed first in a horizontal and stable state, avoiding the difficulty of screw alignment and installation offset caused by uneven force in the tilted state.

[0015] (2) The modular building integrates a solar photovoltaic power generation device. The rotating plate, supported by the contact plate, blocks the handle. By blocking the handle with the rotating plate, the handle is kept at a preset height to prevent movement and slippage, and to reduce the physical effort required to adjust the angle. At the same time, the second spring pushes the round rod to reset. By setting the second spring, it is ensured that the sliding seat can only be released by manual pushing, preventing accidental contact or release, which helps to improve the safety of photovoltaic panel installation.

[0016] (3) The prefabricated building integrates a solar photovoltaic power generation device. The elastic plate applies resistance to the linkage block, slowing down the reset speed of the linkage block. The T-shaped block restricts the rotation range of the elastic plate, so that the reset speed of the linkage block is slowed down under the action of resistance, preventing collisions during reset. At the same time, the rectangular block blocks the linkage block. By quickly changing the position of the C-shaped frame, the process of releasing the blocking function is simplified, which helps to improve the flexibility of photovoltaic panel angle adjustment operation.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-9 One embodiment of the present invention is: a prefabricated building-integrated solar photovoltaic power generation device, including a ground joist 1 and photovoltaic panels. The ground joist 1 is fixed to the ground and includes: a support frame 2, which is fixedly installed on the top of the ground joist 1 and has through holes; a lifting frame 3, which is slidably installed inside the support frame 2; a mounting frame 4, which rotatably passes through the inner and outer walls of the lifting frame 3 and has internally threaded blind holes at the top for installing photovoltaic panels; a movable frame 5, which is slidably installed on the top of the ground joist 1 and rotatably connected to the end of the mounting frame 4 away from the lifting frame 3; a handle 6, which slidably passes through the inner and outer walls of the lifting frame 3; a first spring 7, which is disposed between the handle 6 and the lifting frame 3; and a fixing block 8, which is fixedly installed on the top of the lifting frame 3 and has internally threaded through holes. The fixed block 8 provides support for one end of the mounting frame 4 by sliding the movable frame 5 on the ground joist 1, facilitating the installer to adjust the tilt angle of the mounting frame 4.

[0021] A mounting plate 9 is fixedly installed on the outer wall of the support frame 2. A limiting block 10 is fixedly installed on the side of the mounting plate 9 near the ground keel 1. A rubber plate 11 is fixedly installed on the inner wall of the mounting plate 9. By stabilizing the grip rod 6, the installer is allowed to temporarily release the grip rod 6 to perform other operations during the angle adjustment process, ensuring the continuity of the photovoltaic panel installation process.

[0022] The bottom of the limiting block 10 has a lower groove, and the top of the rubber plate 11 has an upper groove. The circumferential surface of the handle 6 contacts the lower groove. By using the stable mounting bracket 4, the photovoltaic panel can be installed first in a horizontal and stable state, avoiding the difficulty of screw alignment and installation offset caused by uneven force in the tilted state.

[0023] In this embodiment, the photovoltaic panel is placed horizontally on top of the mounting frame 4. The position is adjusted so that the holes of the photovoltaic panel and the mounting frame 4 are vertically aligned. Screws are screwed into the surface of the photovoltaic panel and gradually tightened to fix the photovoltaic panel and the mounting frame 4. During this process, the limit lever 6 maintains the stability of the lifting frame 3 and reduces the shaking of the mounting frame 4 when the screws are tightened. After fixing, the lever 6 is manually pulled outward. The lever 6 moves and stretches the first spring 7, and disengages from the limit of the lower groove. Then, the lever 6 is lifted vertically. The lever 6 drives the lifting frame 3 to move upward. The lifting frame 3 drives one end of the mounting frame 4 to rise synchronously. The other end of the mounting frame 4 slides towards the support frame 2 through the movable frame 5, forming an overall tilt angle. When the lifting frame 3 reaches the preset height, the lever 6 is controlled to return to its original position, and the deformed first spring 7 returns to its original state. By stabilizing the mounting frame 4, the photovoltaic panel is installed first in a horizontal and stable state, avoiding tilting. Under normal conditions, screw alignment is difficult, and uneven force can lead to installation misalignment. When the lifting frame 3 moves upward, it simultaneously drives the fixing block 8 to rise vertically. When the fixing block 8 reaches the preset height, its internal thread blind hole and the through hole on the support frame 2 are aligned in the parallel direction. At this time, the screw is inserted into the through hole of the support frame 2 and screwed into the internal thread blind hole of the fixing block 8. By tightening the screw, the support frame 2 and the fixing block 8 are fixed, locking the tilt angle of the photovoltaic panel. When the handle 6 moves above the mounting plate 9, the installer can control the handle 6 to move downward. The handle 6 moves and contacts the upper groove of the rubber plate 11. The rubber plate 11 forms frictional resistance through elastic deformation. As the handle 6 continues to move downward, it presses against the inner wall of the upper groove, making the rubber plate 11 and the handle 6 in close contact, improving the stability of the handle 6. By stabilizing the handle 6, the installer is allowed to temporarily release the handle 6 to perform other operations during the angle adjustment process, ensuring the continuity of the photovoltaic panel installation process.

[0024] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the support frame 2 is provided with a protective device for improving the safety of angle adjustment, and the protective device is provided with an auxiliary device for improving the flexibility of angle adjustment; the protective device includes a rectangular plate 111, a sliding seat 112, a rotating plate 113, a contact plate 114, and a handle 115. The rectangular plate 111 is fixedly installed on the outer wall of the support frame 2, the sliding seat 112 is slidably installed on the inner wall of the rectangular plate 111, the rotating plate 113 is rotatably installed on the inner wall of the sliding seat 112, the contact plate 114 is fixedly installed on the inner wall of the rectangular plate 111, and the handle 115 is fixedly installed on the bottom of the sliding seat 112. The bottom of the rectangular plate 111 is provided with a movable groove, and the circumferential surface of the handle 115 contacts the movable groove. The top of the rotating plate 113 is provided with an arc-shaped groove. The rotating plate 113 applies a block to the handle 6, ensuring that the handle 6 is stably stopped at a preset height, preventing movement and sliding, and reducing the physical exertion when adjusting the angle.

[0025] A rectangular groove is provided on the top of the rectangular plate 111, and a round rod 116 slides through the rectangular groove. A round plate is fixedly installed on the circumference of the round rod 116. A second spring 117 is provided between the round plate and the rectangular plate 111. By providing the second spring 117, it is ensured that the sliding seat 112 can be released from the obstruction when pushed manually, preventing accidental contact or release, and helping to improve the safety of photovoltaic panel installation.

[0026] A linkage block 118 is fixedly installed on the circumferential surface of the round rod 116. A torsion spring is provided between the rotating plate 113 and the sliding seat 112. The torsion spring is used for the rotation and reset of the rotating plate 113. By setting the torsion spring, the rotation speed of the rotating plate 113 is accelerated, ensuring that the rotating plate 113 can accurately apply resistance to the grip rod 6.

[0027] The auxiliary device includes a fixed frame 121, a rotating shaft 122, an elastic plate 123, and a T-shaped block 124. The fixed frame 121 is fixedly installed on the top of the rectangular plate 111. The rotating shaft 122 rotates through the inner wall of the fixed frame 121. The elastic plate 123 is fixedly installed on the circumferential surface of the rotating shaft 122. The T-shaped block 124 is fixedly installed on the inner wall of the fixed frame 121. A second torsion spring is provided between the rotating shaft 122 and the fixed frame 121. The T-shaped block 124 and the side of the elastic plate 123 near the support frame 2 are in contact. The rotation range of the elastic plate 123 is limited by the T-shaped block 124, so that the reset speed of the linkage block 118 is slowed down under the action of resistance, preventing collision during reset.

[0028] The inner wall of the fixed frame 121 is provided with a moving groove, and a lifting rod 125 is slidably installed in the moving groove. A C-shaped frame 126 is fixedly installed on the circumferential surface of the lifting rod 125, and a rectangular block 127 is fixedly installed at the bottom of the C-shaped frame 126. By quickly changing the position of the C-shaped frame 126, the process of removing the obstruction function is simplified, which helps to improve the flexibility of photovoltaic panel angle adjustment operation.

[0029] In this embodiment, during operation, the grip 6 moves upward and contacts the bottom of the rotating plate 113. Continuing to move upward applies a vertical thrust to the rotating plate 113, causing it to rotate upward. As the rotating plate 113 rotates, it disengages from the contact plate 114, stretching the first torsion spring during rotation. When the contact surfaces of the grip 6 and the rotating plate 113 separate, the torsion spring returns to its original position, causing the rotating plate 113 to reset and re-engage with the contact plate 114. At this point, the grip 6 is controlled to move downward, contacting the arc-shaped groove. Supported by the contact plate 114, the rotating plate 113 blocks the grip 6 from further downward movement. This blocking action by the rotating plate 113 ensures the grip 6 remains stably at the preset height, preventing slippage and reducing physical exertion during angle adjustment. When the grip 6 needs to be moved downward, the installer manually pushes the handle 11. 5. Move the handle 115 away from the contact plate 114. The handle 115 drives the sliding seat 112 to move synchronously. The sliding seat 112 further drives the rotating plate 113 to move. During the movement, the rotating plate 113 disengages from the handle 6, thereby releasing the obstruction to the handle 6. At this time, the handle 6 can be smoothly moved down to the designated position. At the same time, the movement of the sliding seat 112 drives the round rod 116 to move synchronously. The round rod 116 compresses the second spring 117 and drives the linkage block 118 to move synchronously. After the handle 6 has moved down, release the handle 115. The second spring 117 returns to its original position and pushes the round rod 116 back to its original position, thereby driving the sliding seat 112 and the rotating plate 113 back to their initial positions. By setting the second spring 117, it is ensured that the sliding seat 112 can only be released from obstruction by manual pushing, preventing accidental contact or release, which helps to improve the safety of photovoltaic panel installation. The linkage block 118 moves and contacts the elastic plate 123, pushing the elastic plate 123 to rotate, causing the contact surface between the elastic plate 123 and the T-shaped block 124 to separate. Simultaneously, the elastic plate 123 drives the rotating shaft 122 to rotate synchronously, stretching the second torsion spring. When the linkage block 118 disengages from the elastic plate 123, the second torsion spring returns to its original position, causing the rotating shaft 122 to rotate back. The rotation of the rotating shaft 122 causes the elastic plate 123 to reset, returning to its initial position and re-contacting the T-shaped block 124. At this time, the round rod 116 resets, causing the linkage block 118 to reset synchronously. The reset linkage block 118 contacts the elastic plate 123 and compresses it. The deformed elastic plate 123 applies resistance to the linkage block 118, slowing down its reset speed. The T-shaped block 124 limits the rotation range of the elastic plate 123, thus slowing down the reset speed of the linkage block 118 under the action of resistance. To prevent collisions during reset, when the rotating plate 113 does not need to obstruct the handle 6, the sliding seat 112 is pushed towards the fixed frame 121. When the sliding seat 112 moves to the designated position, the C-shaped frame 126 is pulled upward. The movement of the C-shaped frame 126 causes the lifting rod 125 and the rectangular block 127 to rise synchronously. When the C-shaped frame 126 moves to the designated height, the sliding seat 112 is pushed until the linkage block 118 contacts the fixed frame 121. At this time, the C-shaped frame 126 is pushed downward to reset. The reset of the C-shaped frame 126 causes the lifting rod 125 and the rectangular block 127 to move downward synchronously. After the rectangular block 127 resets to the starting position, it obstructs the linkage block 118, forming a limit, thereby stopping the obstruction of the rotating plate 113 on the handle 6. By quickly changing the position of the C-shaped frame 126, the process of releasing the obstruction function is simplified, which helps to improve the flexibility of photovoltaic panel angle adjustment operation.
