It mainly consists of three major parts: solar panels, controllers, and inverters, and the main components are composed of electronic components.

[0003] The patent with the patent announcement number CN210578359U relates to a photovoltaic power generation device convenient for maintenance, including a bottom plate. A motor is fixedly installed at the bottom of the bottom plate. A first bevel gear is fixedly sleeved on the output shaft of the motor. Two threaded rods are rotatably installed on the bottom plate. A second bevel gear is fixedly sleeved on any one of the threaded rods, and the first bevel gear meshes with the second bevel gear. Pulley wheels are fixedly sleeved on both threaded rods, and the same belt is wound between the two pulley wheels. Connecting blocks are respectively threadedly installed on the two threaded rods.

However, it is inconvenient to remove the photovoltaic power generation panel for replacement during maintenance, resulting in difficult operation during maintenance and affecting the maintenance efficiency. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a photovoltaic power generation device convenient for maintenance, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is implemented by the following technical solutions: A photovoltaic power generation device convenient for maintenance, comprising: a support frame disposed on the ground; a fixing frame fixedly installed on the top of the support frame; a support seat fixedly installed inside the fixing frame; a fixing seat fixedly installed on the inner wall of the fixing frame; a photovoltaic panel disposed between the support seat and the fixing seat; a sliding rod slidably installed on the inner wall of the support seat; a limiting plate fixedly installed on the top of the sliding rod; a pull rod fixedly installed on the top of the limiting plate; a fixing block fixedly installed on the surface of the sliding rod; a limiting groove opened on the inner wall of the support seat. By installing the photovoltaic panel on the support seat and supporting the photovoltaic panel by the support seat and the fixing seat, it is convenient to disassemble the photovoltaic panel safely. Subsequently, pulling the pull rod upward, the upward movement of the pull rod will drive the limiting plate upward.

[0007] According to the above technical solution, the fixing block slides on the inner wall of the limiting groove, and the limiting plate is disposed above the photovoltaic panel. By moving the limiting plate downward, the photovoltaic panel will be limited.

The limiting device includes a rotating ring and a fixing plate. By pulling the pull rod upward, the upward movement of the pull rod will drive the limiting plate and the sliding rod upward. The upward movement of the sliding rod will drive the rotating ring upward. The upward movement of the rotating ring will drive the fixing plate upward. The upward movement of the fixing plate will push the photovoltaic panel upward. The rotating ring is rotatably installed on the circumferential surface of the sliding rod, and the fixing plate is fixedly installed on the circumferential surface of the rotating ring.

When the pulley frame moves away from the rotating plate, it will push the triangular plate toward the photovoltaic panel. The movement of the triangular plate toward the photovoltaic panel will drive the sliding plate toward the photovoltaic panel.

[0010] According to the above technical solution, a first spring is provided between the fixing seat and the sliding plate.

When maintenance is required, just pull the pull rod to rotate in the reverse direction, which is convenient for maintenance and replacement. At the same time, the downward movement of the limiting plate will drive the sliding rod downward, and the downward movement of the sliding rod will drive the fixing block downward. Then rotate the pull rod to lock the fixing block into the limiting groove to limit the limiting plate and improve the installation stability.

[0015] (2) In this invention, by pulling the pull rod upward, the upward movement of the pull rod will drive the limiting plate and the sliding rod upward. The upward movement of the sliding rod will drive the rotating ring upward, and the upward movement of the rotating ring will drive the fixing plate upward.

The movement of the triangular block 112 in the direction closer to the photovoltaic panel 4 pushes the L-shaped plate 113 downward. The downward movement of the L-shaped plate 113 drives the photovoltaic panel 4 to move downward. By moving the photovoltaic panel 4 downward, the photovoltaic panel 4 is clamped between the support base 3 and the fixed base 31, improving the installation stability. At the same time, moving the skateboard 106 in the direction closer to the photovoltaic panel 4 drives the trapezoidal block 116 to move in the direction closer to the photovoltaic panel 4.
