Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to an adjustable solar photovoltaic power generation device. Background Art

[0002] Traditional solar photovoltaic power generation devices are mostly installed at a fixed tilt angle and cannot adjust the angle in real time according to changes in the sun's position, resulting in reduced light energy conversion efficiency, especially in the morning and evening or during seasonal changes. To improve power generation efficiency, adjustable photovoltaic devices have gradually developed, such as single-axis or dual-axis tracking systems, which adjust the orientation of photovoltaic panels through mechanical structures to track the trajectory of the sun. However, existing adjustment technologies still have limitations, such as complex mechanical structures, high energy consumption, high maintenance costs, insufficient wind resistance, and easy damage in severe weather.

[0003] Patent publication number CN218217228U discloses an angle-adjustable solar photovoltaic panel. The patent includes a support rod and a solar photovoltaic panel, with the panel mounted on the support rod. A first motor and a gear cooperate to drive the panel to rotate in accordance with the sun's rising and setting trajectory, ensuring it always faces the sun. A second motor and a photoresistor cooperate to sense the horizontal direction of the sun's intensity and adjust the panel's horizontal rotational direction at any time. A circular disc is provided to increase the device's stability. While this patent addresses the aforementioned issues, it still leaves the panel vulnerable to environmental influences and makes it difficult to stabilize the panel after a fixed angle. Therefore, an adjustable solar photovoltaic power generation device is proposed to address these concerns. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an adjustable solar photovoltaic power generation device in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: an adjustable solar photovoltaic power generation device, including an electric lift, the top of the electric lift is fixedly connected to a dual-axis motor housing, the inner surfaces of both sides of the dual-axis motor housing are rotatably connected to a rotating shaft, the circumferential surface of the rotating shaft is fixedly connected to a rotating block, the upper surface of the rotating block is fixedly connected to the photovoltaic power generation panel, the outer side of the electric lift is provided with a support device for improving the supporting strength, the rear side of the electric lift is provided with an energy storage device for facilitating energy storage when adjusting the height of the device, The lower surface of the electric panel is fixedly connected to an arc-shaped positioning frame, and a positioning hole is provided on the inner side of the arc-shaped positioning frame, and the bottom of the outer surface of the dual-axis motor housing is fixedly connected to a connecting frame, and a dual-axis motor is arranged inside the dual-axis motor housing, and the support shaft and the circumferential surface of the rotating shaft are socketed. When the electric lift is started, the free end of the electric lift extends upward to drive the dual-axis motor housing and the rotating shaft to move upward, and the rotating shaft drives the rotating block and the photovoltaic power generation panel to move upward, and the dual-axis motor is started. The dual-axis motor drives the rotating shaft to rotate, and the rotating shaft drives the rotating block to rotate, and the rotating block drives the photovoltaic power generation panel to rotate and change the angle. When the photovoltaic power generation panel rotates, it drives the arc-shaped positioning frame to rotate. When the photovoltaic power generation panel stops, the knob is turned, and the knob drives the screw to rotate. The screw rotates downward in the L-shaped connecting plate through the thread and is inserted into the positioning hole provided on the arc-shaped positioning frame, thereby locking the arc-shaped positioning frame, and the arc-shaped positioning frame then locks the photovoltaic power generation panel.

[0006] The top end of the lifting post is fixedly provided with a lifting post, and the bottom end of the lifting post is fixedly connected with the contact plate. The limiting slot is provided on the inner side of the supporting link, and a torsion spring is provided at the hinge place of the limiting slide rail and the supporting link, and the one end of the reinforcement rod away from the supporting link is hinged to the movable support leg, and the contact plate is slidably connected to the inner surface of the movable support leg, and the contact plate and the limiting slide rail are fixedly connected. The inner surface is slidably connected, and the limit slide rail and the inner surface of the limit groove are in contact with each other. When the photovoltaic panel is raised, the movable support leg is pulled in the direction away from the electric lift. The movable support leg is connected to the electric lift through the support link and the limit slide rail. When the dual-axis motor housing moves upward, it drives the connecting frame to move upward, and the connecting frame drives the lifting column to move upward. The lifting column drives the contact plate to slide upward in the limit slide rail, and the contact plate is stuck in the limit slide rail through the limit groove to make the lifting process more stable. The contact plate pushes the movable support leg to move to the side away from the electric lift through the guidance of the inclined surface, so that when the device rises, the movable support leg can automatically move away from the electric lift to increase the support area. When the movable support leg is away from the electric lift, the reinforcement rod is pulled to unfold.

[0007] Preferably, the energy storage device includes a fixing plate, the rear side of the fixing plate is fixedly connected to a mounting bracket, the rear side of the mounting bracket is fixedly connected to an energy storage box, both sides of the energy storage box are fixedly connected to conductive wires, the energy storage device also includes a U-shaped wire take-up frame, the U-shaped wire take-up frame is provided with a through groove on the side away from the energy storage box, both sides of the energy storage box are fixedly connected to convex shafts, the circumferential surface of the convex shaft is rotatably connected to a roller, the fixing plate is fixedly connected to the side surface of the contact plate, the U-shaped wire take-up frame is fixedly connected to both sides of the energy storage box, the conductive wire is fixedly connected to the lower surface of the photovoltaic panel, the conductive wire and the inner surface of the U-shaped wire take-up frame are in contact with each other, and the conductive wire is fixedly connected to the lower surface of the photovoltaic panel. The conductive wire and the circumferential surface of the roller are in contact with each other. After the photovoltaic panel absorbs light energy, it transmits the energy to the energy storage box for storage through the conductive wire. When the contact plate moves upward, it drives the fixed plate upward, and the fixed plate drives the mounting frame upward. The mounting frame drives the energy storage box upward, so that the distance between the energy storage box and the photovoltaic panel remains consistent. The end of the conductive wire close to the energy storage box is put into the U-shaped wire-receiving frame, which can reduce the impact of the photovoltaic panel on the conductive wire when it rotates. When the conductive wire is pulled by the photovoltaic panel, it generates friction with the roller. When the roller is subjected to friction, it rotates on the convex shaft, thereby reducing the friction. When the conductive wire needs to be removed, the conductive wire is pulled out of the U-shaped wire-receiving frame from the through slot.

[0008] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. The adjustable solar photovoltaic power generation device uses a rotating shaft to drive the rotating block and the photovoltaic power generation panel to move upward, thereby adjusting the height of the photovoltaic power generation panel, making it easier for the device to be used in different environments. The rotating block drives the photovoltaic power generation panel to rotate and change the angle, so that the photovoltaic power generation panel can absorb light energy more efficiently. The screw locks the arc positioning frame, and the arc positioning frame then locks the photovoltaic power generation panel to prevent the photovoltaic power generation panel from being affected in a strong wind environment, thereby avoiding a decrease in the effect of the photovoltaic power generation panel in absorbing light energy.

[0009] 2. The adjustable solar photovoltaic power generation device has movable support legs connected to the electric lift through support links and limit slides, which increases the support area of the electric lift and thereby increases the support strength when the device is raised, preventing the device from tilting due to external forces such as strong winds after the center of gravity becomes higher, thereby improving the stability of the device.

[0010] 3. In this adjustable solar photovoltaic power generation device, the contact plate pushes the movable support leg to move to the side away from the electric lift through the guidance of the inclined surface, so that when the device rises, the movable support leg can automatically move away from the electric lift to increase the support area, which promotes the convenience of using the device. When the movable support leg moves away from the electric lift, the reinforcement rod is pulled to unfold, further improving the support strength of the device.

[0011] 4. This adjustable solar photovoltaic power generation device absorbs light energy and transmits the energy to the energy storage box through the conduction line for storage, which improves the energy storage and endurance of the device. The mounting frame drives the energy storage box to move upward, so that the distance between the energy storage box and the photovoltaic power generation panel remains consistent, which facilitates energy transmission.

[0012] 5. This adjustable solar photovoltaic power generation device stores the end of the conductive wire close to the energy storage box in a U-shaped wire-receiving frame, which can reduce the impact of the photovoltaic panel on the conductive wire when it rotates, prevent the conductive wire from being frequently pulled and worn, and improve the service life and safety of the device. When the roller is subjected to friction, it rotates on the convex shaft, thereby reducing the friction force and further reducing the wear on the surface of the conductive wire. The conductive wire is pulled out of the U-shaped wire-receiving frame from the through groove, which improves the convenience of using the device. BRIEF DESCRIPTION OF THE DRAWINGS
