Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically to a photovoltaic panel base that is easy to install. Background Technology

[0002] Traditional photovoltaic panel base installation suffers from low efficiency and high cost. Ground-mounted power stations typically require on-site pouring and curing of concrete foundations, which takes a long time. Helical ground piles rely on large machinery and have poor site adaptability. The counterweight base of rooftop power stations is too heavy, and penetrating fixing can damage the waterproof layer, posing a risk of leakage. In addition, bolt connection installation is cumbersome, and high-altitude operations are inefficient and prone to errors. Therefore, there is an urgent need for a new type of lightweight, modular base that can be quickly installed and adapted to various environments to meet the needs of the rapidly developing photovoltaic industry.

[0003] A search revealed a Chinese patent publication number, CN222073060U, which discloses a photovoltaic module mounting base. This patent features an angle-adjusting component between the top of the inner side of the mounting bracket and the outer side of the mounting base. During use, the mounting base's pitch angle is adjusted by rotating the rotating shaft according to different local solar direct angles. A threaded sleeve is positioned with corresponding positioning holes at different angles, and a positioning bolt is then inserted through these holes and fixed into the threaded sleeve via a threaded connection. This achieves a stable mounting base, making it suitable for regions with varying solar direct angles and allowing adjustment of the photovoltaic module's orientation after installation, thus enhancing its practicality.

[0004] Although the aforementioned patent can adjust the angle of photovoltaic modules, the above-mentioned adjustment of the pitch angle still has the following problems: the photovoltaic module mounting base is equipped with threaded sleeves, positioning holes and bolts, so when adjusting the angle, the workers have to loosen the bolts on both sides first, and after adjusting the angle, they still need to adjust on both sides. The operation is cumbersome, it is difficult to ensure synchronization, and the installation efficiency is reduced. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content

[0018] Please see Figures 1-6 This utility model provides a technical solution: a photovoltaic panel base that is easy to install, including a chassis 1. A bidirectional threaded rod 2 is rotatably connected inside the chassis 1. A motor 6 is fixedly installed on one side of the chassis 1. The motor 6 is an existing structure and will not be described in detail here. The output end of the motor 6 rotatably passes through the interior of the chassis 1 and is fixedly connected to one end of the bidirectional threaded rod 2. A first moving plate 4 and a second moving plate 5 are threadedly connected to the outer surface of the bidirectional threaded rod 2. The operator starts the motor 6 through an external control device, causing the bidirectional threaded rod 2 to rotate, thereby causing the first moving plate 4 and the second moving plate 5 on the surface of the bidirectional threaded rod 2 to move in opposite directions or in opposite directions. A first rotating shaft 7 is rotatably connected to one side of the first moving plate 4. The first rotating shaft 7 has an internal opening... A square sliding groove is used to slide a second rotating shaft 8 inside the first rotating shaft 7. One end of the second rotating shaft 8 slides through the interior of the first rotating shaft 7 and is rotatably connected to one side of the second moving plate 5. The first rotating shaft 7 and the second rotating shaft 8 are slidably connected through the square sliding groove, which can realize the synchronous rotation of the first rotating shaft 7 and the second rotating shaft 8. A photovoltaic panel clamping device and an angle fixing device are provided on the outer surface of the first rotating shaft 7. Driven by the combination of the bidirectional threaded rod 2 and the motor 6, the first moving plate 4 and the second moving plate 5 can accurately perform opposite or reverse movements, thereby realizing the automatic adjustment of the support width to adapt to photovoltaic panels of different sizes, while reducing manual pushing, improving the efficiency of the device and increasing work efficiency.

[0019] Two limiting rods 3 are fixedly installed inside the chassis 1. The two limiting rods 3 are set on both sides of the bidirectional threaded rod 2. The outer surface of the limiting rods 3 is slidably connected to the inside of the first moving plate 4 and the second moving plate 5. The setting of the limiting rods 3 plays a limiting role in the movement of the first moving plate 4 and the second moving plate 5.

[0020] The photovoltaic panel clamping device includes a clamping plate 9. The bottom of the clamping plate 9 is fixedly connected to the outer surface of the first rotating shaft 7. The outer surface of the second rotating shaft 8 is also fixedly connected to the clamping plate 9. A fixed clamping plate 23 is fixedly connected to one end of the clamping plate 9.

A threaded connection is provided on one side of the strip-shaped slider 27. There is a clamping bolt 26. The sliding of the movable clamping plate 24 is fixed by rotating the clamping bolt 26. When the staff needs to place the photovoltaic panel, the motor 6 is started first. The motor 6 drives the bidirectional threaded rod 2 to rotate, so that the first movable plate 4 and the second movable plate 5 move, thereby adjusting the width of the photovoltaic panel clamping device. Then, the position of the movable clamping plate 24 is adjusted by sliding, and then the clamping bolt 26 is rotated to fix the position of the movable clamping plate 24, thereby clamping and fixing the photovoltaic panel.

The gear 16 meshes with the rack 12 through the opening of the angle fixing plate 10. One end of the gear shaft 15 rotatably passes through the outside of the gear housing 14 and is fixedly connected to a turntable 18. By rotating the turntable 18, the gear 16 rotates. The gear 16 meshes with the rack 12, thereby driving the rack 12 to slide inside the angle fixing plate 10, thereby locking or releasing the positioning groove 11 to fix and adjust the angle of the first rotating shaft 7. The turntable 18 is provided with an adjustment fixing device. Through the meshing transmission of the gear 16 and the rack 12 and the cooperation of the multiple positioning grooves 11, the angle of the rotating shaft can be precisely fixed in multiple positions, ensuring that the photovoltaic panel remains stable at various angles.

[0022] The angle fixing plate 10 has two slots inside that fit the outer surface of the limiting rod 3. The angle fixing plate 10 is slidably connected to the outer surface of the limiting rod 3 through the slots, thereby limiting the angle fixing plate 10.

[0023] A connecting plate 25 is fixedly installed on the side of the first movable plate 4 near the angle fixing plate 10. The end of the connecting plate 25 away from the first movable plate 4 is fixedly connected to the side of the angle fixing plate 10. The connecting plate 25 enables the first movable plate 4 and the angle fixing plate 10 to move synchronously.

[0024] The adjustment fixing device includes a pin sleeve 19, which is fixedly installed on the side of the turntable 18 away from the gear housing 14. The gear housing 14 has an internal groove, and a pin 20 is slidably connected inside the gear housing 14. A protrusion is provided on the outer surface of the pin 20. A second return spring 21 is fixedly installed at one end of the internal groove of the gear housing 14, and one end of the second return spring 21 is fixedly connected to the protrusion on the outer surface of the pin 20. The end of the pin 20 away from the gear housing 14 slides through to the outside of the pin sleeve 19 and is rotatably connected to a pin handle 22. A positioning hole 17 is provided on the side of the gear housing 14 near the turntable 18. Two positioning holes 17 are provided. The end of the pin 20 near the gear housing 14 slides through the pin sleeve 19 and the turntable 18 in sequence and extends into the interior of the positioning hole 17. When the angle of the photovoltaic panel clamping device needs to be adjusted, the operator first pulls the pin 20 out of the positioning hole 17 through the pin handle 22, then rotates the turntable 18 to separate the rack 12 from the positioning groove 11. At the same time, the pin 20 is inserted into the second positioning hole 17 under the force of the second return spring 21, thereby fixing the position of the rack 12. Then, the first rotating shaft 7 and the second rotating shaft 8 are rotated to adjust the angle of the photovoltaic panel clamping device. After that, the pin 20 is pulled out again, and the turntable 18 is rotated to insert the pin 20 into the first positioning hole 17 to fix the turntable 18 and thus fix the rack 12. Through the cooperation of the pin 20 and the double positioning holes 17, the operator can temporarily fix the transmission mechanism when releasing the rack 12 to adjust the angle, freeing up their hands and realizing safe and convenient single-person operation.

[0025] Working principle: For this type of easy-to-install photovoltaic panel base, the starting motor 6 drives the bidirectional threaded rod 2 to rotate, causing the first moving plate 4 and the second moving plate 5 to move in opposite directions along the limiting rod 3 to adjust the support width. At the same time, the sliding connection between the first rotating shaft 7 and the second rotating shaft 8 causes the clamping plate 9 on its surface to move to adapt to the size of the photovoltaic panel. Then, the sliding clamping plate 24 is fixed by the clamping bolt 26 to hold the photovoltaic panel. When angle adjustment is required, the pin 20 is pulled out and the turntable 18 is rotated, causing the gear 16 to drive the rack 12 to disengage from the positioning groove 11, thereby adjusting the angle of the first rotating shaft 7. After adjustment, the pin 20 is used to fix the turntable 18 with the positioning hole 17 to achieve a firm lock of the angle.
