Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a rooftop photovoltaic installation device. Background Technology

[0002] As a green and environmentally friendly new energy solution, photovoltaic technology requires photovoltaic panels, the core component of which, to be stably positioned using specialized installation equipment. This is the foundation for ensuring the efficient operation and long-term reliability of the subsequent power generation system. Therefore, the practicality and adaptability of the installation equipment are crucial for the promotion of photovoltaic applications.

[0003] Currently, relevant technical solutions have been explored for rooftop photovoltaic installation devices. For example, patent application number CN202321584632.8 discloses a structure that includes a fixed rod, a telescopic rod, a mounting frame, and a dust removal component. The height is adjusted by the telescopic rod, the fixed component is used to attach the photovoltaic panel, and the dust removal component is used to keep the surface of the photovoltaic panel clean. This structure meets the basic installation and daily maintenance needs to a certain extent and has certain practical value.

[0004] However, existing photovoltaic (PV) installations still have significant shortcomings, making it difficult to fully adapt to actual application scenarios. On the one hand, PV panels are often installed in a fixed, tilted layout, and the rear panels are often installed at a higher position, requiring workers to climb to heights for later adjustments, component inspections, or cleaning and maintenance. This not only increases the difficulty of the work but also carries higher safety risks. On the other hand, once the installation is in place, the arrangement of the PV panels is often fixed and cannot be adjusted according to the roof space layout, changes in the angle of sunlight, or power generation needs. This poor adaptability limits the improvement of the overall power generation efficiency of the PV system and its adaptability to different application scenarios. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a rooftop photovoltaic installation device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rooftop photovoltaic installation device, comprising: two strip-shaped base frames, with connecting rods welded in a linear array between the two base frames; four support rods are fixedly connected to one side of the top of the base frames, the height of the two front support rods being less than the height of the two rear support rods, and a front photovoltaic panel is fixedly fixed to the top of the four support rods for receiving sunlight and performing photoelectric conversion; a transverse moving assembly is provided on the other side of the top of the base frames, and a sliding plate is slidably connected to the transverse moving assembly, the sliding plate being able to move laterally on the transverse moving assembly, thereby adjusting the lateral position of the sliding plate and subsequent components; a lifting assembly is connected to the top of the sliding plate, and a rear photovoltaic panel is fixed to the lifting assembly, the lifting assembly being able to drive the rear photovoltaic panel to rise or fall, thereby flexibly adjusting the height of the rear photovoltaic panel.

[0007] By adopting the above technical solution, the position of the rear photovoltaic panel can be changed, which facilitates installation and maintenance. In addition, after the device is installed, the arrangement of the front and rear photovoltaic panels can be adjusted according to needs.

[0008] Furthermore, the lateral movement assembly includes two support plates fixedly connected to the top of the base frame. The two support plates are arranged opposite to each other, and two limiting slide rods are symmetrically fixed between the two support plates. The cross-section of the limiting slide rods is rectangular.

[0009] By adopting the above technical solution, the two limiting slide rods can be stably connected between the two support plates.

[0010] Furthermore, rectangular sliding holes are symmetrically provided on the sliding plate corresponding to the positions of the two limiting sliding rods, and the sliding plate slides in cooperation with the limiting sliding rods through the rectangular sliding holes.

[0011] By adopting the above technical solution, the sliding plate can move left and right on the limiting slide rod through the rectangular sliding hole.

[0012] Furthermore, multiple threaded holes are spaced apart on both sides of the limiting slide rod along its length, and positioning holes are provided on the sliding plate at the positions corresponding to the threaded holes. Bolts pass through the positioning holes and are threadedly connected to the threaded holes to position the sliding plate at the target position of the limiting slide rod.

[0013] By adopting the above technical solution, the sliding plate can be positioned on the limiting slide rod by bolts.

[0014] Furthermore, the lifting assembly includes vertical support plates fixedly installed on both sides of the top of the sliding plate. A through-hole is provided on the vertical support plate along the height direction, and the lifting plate is slidably engaged in the through-hole.

[0015] By adopting the above technical solution, the cooperation between the limiting through hole and the lifting plate can limit the lifting trajectory of the lifting plate and prevent it from shifting laterally.

[0016] Furthermore, a drive motor is embedded in the center of the top of the sliding plate, and a drive screw is coaxially fixedly connected to the output shaft of the drive motor. A screw hole adapted to the drive screw is opened in the middle of the lifting plate, and one end of the drive screw passes through the screw hole.

[0017] By adopting the above technical solution, when the drive motor drives the drive screw to rotate, the lifting plate can be displaced.

[0018] Furthermore, a U-shaped stabilizing frame is fixedly connected to the outer wall of the sliding plate, and the end of the drive screw away from the drive motor is rotatably supported on the inner side of the stabilizing frame.

[0019] By adopting the above technical solution, the stability of the drive screw rotation is enhanced by the stabilizer, thus preventing radial sway.

[0020] Furthermore, triangular support frames are fixed on both sides of the top of the lifting plate, and the rear photovoltaic panel is positioned on the inclined surfaces of the two triangular support frames.

[0021] By adopting the above technical solution, the rear photovoltaic panel is positioned on the inclined surface of the triangular support frame, thus maintaining a stable angle of light reception.

[0022] In summary, this utility model has the following beneficial effects: by setting up a lifting component and a lateral moving component, when the rear photovoltaic panel needs to be cleaned or repaired, the lifting component can drive it to descend vertically, allowing for convenient operation without personnel having to climb to a height, greatly reducing maintenance difficulty and safety risks; and after the rear photovoltaic panel descends, the sliding plate can drive the lifting component and the rear photovoltaic panel to move laterally, thereby allowing for flexible adjustment of the arrangement of the front and rear photovoltaic panels according to actual needs, effectively improving the adaptability of the device to different usage scenarios.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figures 1-5 As shown in the figure, this application discloses a rooftop photovoltaic installation device, including two strip-shaped base frames 1, with connecting rods 2 welded in a linear array between the two base frames 1; four support rods 3 are fixedly connected to one side of the top of the base frame 1, the height of the two front support rods 3 is less than the height of the two rear support rods 3, and a front photovoltaic panel 4 is fixedly fixed to the top of the four support rods 3 for receiving sunlight and performing photoelectric conversion; a transverse moving assembly 5 is provided on the other side of the top of the base frame 1, and a sliding plate 6 is slidably connected to the transverse moving assembly 5, which can move laterally on the transverse moving assembly 5 to adjust the lateral position of the sliding plate 6 and subsequent components; a lifting assembly 7 is connected to the top of the sliding plate 6, and a rear photovoltaic panel 8 is fixed on the lifting assembly 7, which can drive the rear photovoltaic panel 8 to rise or fall, thereby flexibly adjusting the height of the rear photovoltaic panel 8.

[0026] In practical use, the rooftop photovoltaic installation device is installed on the roof. The front photovoltaic panel 4 is kept at a fixed tilt angle by four support rods 3 of different heights, continuously and efficiently receiving sunlight to generate electricity. When it is necessary to clean or repair the rear photovoltaic panel 8, the lifting component 7 is activated to drive the rear photovoltaic panel 8 vertically down to a height that is easy to operate. The staff can complete the cleaning or component repair work without climbing, which improves maintenance efficiency and reduces safety risks. If it is necessary to adjust the overall power generation layout, the sliding plate 6 can be moved horizontally on the horizontal moving component 5. With the height adjustment of the lifting component 7, the distance and relative height between the front photovoltaic panel 4 and the rear photovoltaic panel 8 can be flexibly adjusted. This can not only avoid the two from blocking each other to ensure power generation efficiency, but also adapt to the installation and use needs of different scenarios, significantly improving the practicality and adaptability of the device.

[0027] The transverse component 5 includes two support plates 501 fixedly connected to the top of the base frame 1. The two support plates 501 are arranged opposite each other, and two limiting slide rods 502 are symmetrically fixed between the two support plates 501. The cross-section of the limiting slide rods 502 is rectangular. Rectangular sliding holes are symmetrically opened on the sliding plate 6 corresponding to the positions of the two limiting slide rods 502. The sliding plate 6 slides with the limiting slide rods 502 through the rectangular sliding holes. Multiple threaded holes 503 are spaced apart on both sides of the limiting slide rods 502 along its length direction. Positioning holes are opened on the sliding plate 6 corresponding to the positions of the threaded holes 503. Bolts 504 pass through the positioning holes and are threadedly connected to the threaded holes 503 to position the sliding plate 6 at the target position of the limiting slide rods 502.

[0028] When it is necessary to adjust the lateral position of the rear photovoltaic panel 8 to change its arrangement with the front photovoltaic panel 4, the operator can first loosen the bolt 504 that passes through the positioning hole of the sliding plate 6 and the threaded hole 503 of the limiting slide rod 502, so that the sliding plate 6 is released from its fixed state; then push the sliding plate 6 so that it slides smoothly along the rectangular cross-section of the limiting slide rod 502 through the rectangular sliding hole. The rectangular structure can effectively prevent deflection or jamming during the sliding process and ensure the accuracy of lateral displacement; after the sliding plate 6 moves the lifting component 7 and the rear photovoltaic panel 8 to the target position, the bolt 504 is re-passed through the positioning hole of the sliding plate 6 and screwed into the threaded hole 503 of the corresponding position of the limiting slide rod 502 and tightened to complete the stable positioning of the sliding plate 6.

[0029] The lifting assembly 7 includes vertical support plates 701 fixedly installed on both sides of the top of the sliding plate 6. A through-hole is provided on the vertical support plate 701 along the height direction. A lifting plate 702 is slidably engaged in the through-hole. A drive motor 703 is embedded in the center of the top of the sliding plate 6. A drive screw 704 is coaxially fixedly connected to the output shaft of the drive motor 703. A screw hole adapted to the drive screw 704 is provided in the middle of the lifting plate 702. One end of the drive screw 704 passes through the screw hole. A U-shaped stabilizer 705 is fixedly connected to the outer wall of the sliding plate 6. The end of the drive screw 704 away from the drive motor 703 is rotatably supported on the inner side of the stabilizer 705. Triangular support frames 706 are fixed on both sides of the top of the lifting plate 702. The rear photovoltaic panel 8 is positioned on the inclined surface of the two triangular support frames 706.

[0030] In actual use, when the height of the rear photovoltaic panel 8 needs to be adjusted, the drive motor 703 is started, and its output shaft drives the drive screw 704 to rotate synchronously. Under the threaded engagement between the drive screw 704 and the screw hole in the middle of the lifting plate 702, the lifting plate 702 moves vertically up and down along the limiting through hole of the vertical support plate 701. The U-shaped stabilizer 705 provides stable support to the other end of the drive screw 704, effectively preventing radial swaying when the screw rotates and ensuring a smooth and uninterrupted lifting process. The sliding engagement structure between the limiting through hole and the lifting plate 702 further restricts the lifting trajectory and prevents the rear photovoltaic panel 8 from shifting. When the rear photovoltaic panel 8 needs cleaning or maintenance, it can be lowered to a low position by the lifting component 7, allowing staff to operate conveniently without having to climb high, greatly reducing the risk of working at height. During daily power generation, the relative height between the rear photovoltaic panel 8 and the front photovoltaic panel 4 can be adjusted by raising the rear photovoltaic panel 8. Combined with the preset tilt angle of the triangular support frame 706, this can prevent the two from blocking each other when the solar altitude angle changes, and ensure that the rear photovoltaic panel 8 always maintains an efficient angle of receiving sunlight, thus guaranteeing power generation efficiency.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
