Description

Technical Field

[0001] The invention relates to the technical field of new energy photovoltaic power generation, and in particular to a photovoltaic panel device with adjustable direction. Background Art

[0002] In recent years, China's new energy photovoltaic power generation industry has been "advancing rapidly", with the scale of new grid-connected power generation showing a trend of doubling, and the industry showing a trend of diversified development. The scale of new installed capacity in various provinces varies significantly, and the geographical distribution of centralized and distributed photovoltaic power generation is unique. Photovoltaic power generation systems use semiconductor materials with photovoltaic effects to convert solar radiation into electrical energy. They mainly include solar cell arrays, charging controllers, inverters, battery packs, solar tracking control systems and other equipment. The solar tracking control system can actively track the changes in the position of the sun and adjust the angle through the control system of the photovoltaic panel device to ensure that the sun's rays are as vertical as possible to the surface of the photovoltaic module.

[0003] Due to the revolution and rotation of the earth, the angle of solar radiation varies with the seasons and time, while fixed photovoltaic panels can only achieve the optimal sunlight collection efficiency in fixed seasons and fixed time periods, in order to improve the power generation efficiency of photovoltaic power generation systems. After searching, Chinese invention patent 202410565979.0 discloses an adaptive light angle adjustment device for photovoltaic power generation communication equipment, which uses two U-shaped frames to fix the photovoltaic panel and the adjustment panel respectively, and uses the adjustment mechanism to adjust the angle of the photovoltaic panel. Chinese invention patent 202110863346.4 discloses an angle-adjustable solar cell assembly, including a base and a solar cell panel, and the angle of the solar cell assembly is adjusted by a rotating mechanism and a rotating mechanism. The current invention patents mainly involve only adjusting the inclination angle of the photovoltaic panel in the photovoltaic power generation device or the structure is complex. Designing a direction-adjustable photovoltaic power generation device with a simple structure and high solar utilization rate can not only improve the power generation efficiency, but also reduce equipment costs and labor installation costs. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In response to the above technical problems, the present invention provides a direction-adjustable photovoltaic panel device, which can control the angle of the photovoltaic panel according to the sunlight angle changes caused by geographical location changes, seasonal changes and daily time changes, thereby improving the sunlight collection efficiency and increasing the utilization rate of sunlight.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The main components of a photovoltaic panel device with adjustable direction include photovoltaic panels, light source sensors, control, drive motors, fixed bases, racks, connecting rods and several ball joints. The photovoltaic panel is connected to the connecting rods through ball joints; the fixed base surface has two square grooves to constrain the linear motion of the racks; the connecting rods are connected to the racks through ball joints, and the connecting rods are connected to the fixed base through ball joints; the output gear of the drive motor is meshed with the racks;

[0009] Preferably, the photovoltaic panel receives sunlight, and the light source sensor obtains the spatial angle of the light source, and transmits the collected light source signal to the controller. The controller takes the highest light source collection efficiency as the goal, and obtains the rotation angles of the azimuth drive motor and the pitch angle drive motor required for the roll angle and pitch angle of the photovoltaic panel through a built-in algorithm;

[0010] Preferably, the photovoltaic panel azimuth adjustment mechanism includes an azimuth drive motor and its output gear, rack, fixed base, connecting rod and ball joint. The azimuth drive motor rotates, and its output gear meshes with the rack. The square sliding groove constrains the rack to maintain linear motion. At this time, the connecting rod, photovoltaic panel, connecting rod and fixed base form a four-bar mechanism; the gear meshes with the rack to convert the rotation of the gear into the linear motion of the rack. The rack drives the connecting rod to move through the ball joint. The connecting rod drives the photovoltaic panel plane to tilt and displace at a certain angle through the ball joint. The photovoltaic panel drives the connecting rod to rotate around the ball joint through the ball joint. At this time, the photovoltaic panel plane can be continuously adjusted to match the angle change of the sun rising and falling.

[0011] Preferably, the photovoltaic panel pitch angle adjustment mechanism includes a pitch angle drive motor and its output gear, rack, fixed base, connecting rod and ball joint. The pitch angle drive motor rotates, and its output gear meshes with the rack. The square sliding groove constrains the rack to maintain linear motion. At this time, the connecting rod, photovoltaic panel, connecting rod and fixed base form a four-bar mechanism; the gear meshes with the rack to convert the rotation of the gear into linear motion of the rack. The rack drives the connecting rod to move through the ball joint, and the connecting rod drives the plane of the photovoltaic panel to pitch and displace a certain angle through the ball joint. The photovoltaic panel drives the connecting rod to rotate around the ball joint through the ball joint. At this time, the plane of the photovoltaic panel can cooperate with the influence of the changing angle of sunlight caused by the rotation of the earth in four seasons.

The controller 3 takes the highest light source collection efficiency as the goal and obtains the rotation angles of the azimuth drive motor 4 and the pitch angle drive motor 5 required for the roll angle and pitch angle of the photovoltaic panel through the built-in algorithm;

[0026] like Figure 3 As shown, the output gear 23 of the azimuth driving motor 4 is meshed with the rack 21, and the square sliding groove 19 constrains the rack to maintain linear motion.
