Solar automatic tracking device

technical field

The utility model is a solar automatic tracking system which integrates solar power generation technology, microprocessor technology, optical induction technology and single-chip processing technology. The utility model mainly senses sunlight through an optical sensing module, so that the solar battery panel can form a 90-degree angle with the incident light of the light in real time, so as to achieve the maximum efficiency of converting electric energy.

Background technique

At present, most of the solar power generation devices install the solar power generation panels on a fixed support, and the support is fixed on an inclined plane for daylighting and power generation. Although some solar brackets can be manually rotated to align with the sun for light energy collection, this method still requires manual regulation, and it cannot be aligned with the light source in real time for light energy collection, which will still bring a lot of troubles. inconvenient.

Contents of the invention

In the existing solar power generation system, the solar panel is fixed in one direction to collect light energy, and when the sun moves to another direction, the amount of light energy collected is greatly reduced. The technical problem solved by the utility model is to enable the solar panel to align with the light source in real time to collect light energy.

The technical solution adopted by the utility model is to include four photosensitive sensors around the solar panel, above and below the solar fixed plate, a set of solar support parts and a brushless motor composed of two stepper motors. For the pan/tilt, a stepping motor on the side of the bracket is used to control the rotation of the Y axis, and a stepping motor under the bracket is used to control the rotation of the X axis. Through the rotation adjustment of the X-axis stepping motor and the Y-axis stepping motor, it can start PTZ control tasks to solar panels.

Preferably; four photosensitive sensors are installed around a solar panel installed on the solar fixed plate to collect and judge light energy, after the processor receives the data returned by the four photosensitive sensors, Carry out judgment and analysis, and then adjust the angle of the solar panel by controlling the X-axis stepping motor and the Y-axis stepping motor, so that the solar panel is perpendicular to the incident angle of sunlight, and realizes the maximum collection of light sources .

The beneficial effect of a kind of solar energy automatic tracking system of the utility model is:

It can be aimed at the strongest direction of the light source all-weather, so that the solar panel can generate the maximum conversion power, and can pass the maximum conversion power all-weather, and the structure is simple, the circuit is not complicated, and the waste of energy can be effectively reduced.

Detailed ways

The solar automatic tracking device, in Figure 1, is to install 4 photosensitive sensors (1) and solar panels (2) on a solar fixing plate (3), which can play a role of overall fixing and manipulation.

In Figure 2, the gimbal pillar (4), gimbal Y-axis bracket (5), Y-axis rotation bracket (6), XY rotation disc (7), Y-axis rotation disc (8), and Y-axis step The motor (9) is regarded as a whole to move the solar panel (2) in the Y axis. Use the stepper motor support (10), the X-axis motor disk (11), and the X-axis stepper motor (12) to move the X-axis of the solar panel (2). Therefore, when the X-axis stepping motor (12) and the Y-axis stepping motor (9) are rotated to adjust the direction, the solar panel (2) can be moved on a hemispherical trajectory, and the solar panel (2) can be moved Aim at the sun for effective energy harvesting work.

When the control system receives the light source signal collected by the photosensitive sensor (1), it will make a judgment to determine the position of the strongest light source at that time, and control the X-axis stepping motor (12) and Y-axis stepping motor (9) to rotate . When the Y-axis stepping motor (9) rotates, the Y-axis rotating disk (7) will also rotate accordingly and drive the Y-axis bracket (5) of the pan-tilt and the entire solar energy fixing plate (3) to rotate accordingly, which will play a role in turning the solar energy The battery board (2) performs Y-axis rotation. When the X-axis stepping motor (11) rotates, the X-axis motor disk (11) will rotate together, and the X-axis motor disk (11) is connected with the Y-axis stepping motor pillar (10), the Y-axis rotating column (6), etc. The series parts are connected, and when the X-axis stepping motor (12) rotates, it drives the parts connected to it to rotate the X-axis.

When the control system receives the collected information received by the four photosensitive sensors (1), it will make an internal judgment and control the X-axis stepping motor (12) and the Y-axis stepping motor (9) to adjust the orientation so that Keep the solar panel (2) perpendicular to the incident angle of sunlight to achieve the maximum rate of light energy gain.
