Description

Technical Field

[0001] This utility model relates to the field of photovoltaic tracking devices, and in particular to a foldable photovoltaic tracking power generation light box. Background Technology

[0002] Solar energy, as a clean and renewable energy source, has been widely developed and utilized. Especially in remote areas with limited power supply, photovoltaic power generation is an excellent option, eliminating the need for manual battery replacements. However, due to the wide distribution and low energy flux density of solar radiation, generating high-temperature heat requires direct sunlight from solar panels. Since the sun's position is constantly changing, the angle of the solar panels needs to be adjusted to adapt to these changes and achieve higher power output. At night or on cloudy days, the solar panels receive almost no sunlight, resulting in very low efficiency in generating electricity. Exposed solar panels also experience aging, affecting their lifespan. Furthermore, in outdoor environments, changing weather conditions can easily damage the motor. Large solar panels can also cause the entire enclosure to be blown over by the wind, significantly increasing the likelihood of power unit failure and raising maintenance costs. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a foldable photovoltaic tracking power generation light box.

[0004] To solve the above-mentioned technical problems, this utility model achieves its solution through the following technical solution:

[0005] A foldable photovoltaic tracking light box includes a light box, a mounting frame, and a control device. The mounting frame is located above the light box and includes a main frame and photovoltaic tracking wings. At least two photovoltaic tracking wings are provided on the sides of the main frame. The inner side of the photovoltaic tracking wings is connected to the main frame. The photovoltaic tracking wings are connected to a driving device. The driving device drives the outer end of the photovoltaic tracking wings to swing up and down relative to the main frame according to the direction of sunlight. The photovoltaic tracking wings have at least two states: an unfolded state relative to the main frame to receive sunlight and a folded state relative to the main frame to be folded down. A top solar panel is provided on the top of the main frame. When the photovoltaic tracking wings are unfolded relative to the main frame, a solar panel is provided on the upper side. When the photovoltaic tracking wings are folded relative to the main frame, the solar panel is located below the top solar panel. The lightbox provides illumination, and an advertising banner can be placed inside. The electricity generated by the solar panels powers the lights and the motor that raises and lowers the banner, ensuring continuous illumination from batteries in remote or low-visibility areas where power supply is inconvenient. The photovoltaic tracking wings increase the working area of ​​the solar panels within the same space and can be folded inwards during windy, inclement weather, or at night to reduce the area affected by wind, thus improving the stability of the photovoltaic tracking lightbox and protecting the solar panels on the tracking wings.

[0006] Preferably, the power box is equipped with a battery that is electrically connected to the solar panel, a light-transmitting plate is provided on the side of the power box, and a lamp body is provided inside the power box, which is electrically connected to the battery.

[0007] Preferably, the electrical box has an inner and outer layer inside its casing, and a rotating rod for installing advertising cloth is installed on the top of the inner and outer layers. The rotating rod is connected to a motor that drives it to rotate, and the motor is electrically connected to the storage battery.

[0008] Preferably, when the photovoltaic tracking wing changes from the tilted state to the folded state, the flip angle is not less than 180°.

[0009] Preferably, the main frame includes a side limiting part, and a corresponding number of photovoltaic tracking wings are connected to the side of the main frame. When each photovoltaic tracking wing is closed relative to the main frame, the inner surface of the photovoltaic tracking wing is in contact with the corresponding side limiting part.

[0010] Preferably, the photovoltaic tracking wing is connected to the main frame via two hinged links, one end of which is hinged to the photovoltaic tracking wing, and the other link is connected to the drive device on the main frame.

[0011] Preferably, a light sensor is provided on one side of the solar panel of the photovoltaic tracking wing. The light sensor includes a light-blocking partition. A light intensity sensor 1 and a light intensity sensor 2 are respectively provided on the left and right sides of the light-blocking partition. The light intensity sensor 1 and the light intensity sensor 2 are electrically connected to the control device. The light intensity sensor 1 and the light intensity sensor 2 sense the light intensity and transmit the light signal to the control device. The control device drives each drive device to rotate forward or backward according to the comparison of the light intensity on both sides until the light intensity sensed by the light intensity sensor 1 and the light intensity sensor 2 are consistent.

[0012] Preferably, the main frame is a trapezoidal shape that is larger at the top and smaller at the bottom. There is a rectangular side limiting part on each side of the main frame. The front and rear sides of the main frame are inverted trapezoidal. A photovoltaic tracking wing is connected to the outside of the side limiting part. The photovoltaic tracking wing is also rectangular and matches the shape of the side limiting part.

[0013] As a preferred embodiment, the main frame is a truncated pyramid with a larger top and a smaller bottom. Each of the front, back, left, and right sides of the main frame is provided with an inverted trapezoidal side limiting part. A photovoltaic tracking wing is connected to the outside of the side limiting part. The photovoltaic tracking wing is also trapezoidal, and its shape matches the shape of the side limiting part.

[0014] Preferably, a solar panel is also installed on the upper surface of the top solar panel.

[0015] This utility model, by adopting the above technical solution, has significant technical effects:

[0016] By utilizing a side-mounted photovoltaic tracking wing, additional solar panels are added to the sides, thereby increasing the solar panel area and power generation capacity within the same space.

[0017] It adopts a photovoltaic tracking wing that can track sunlight. It can swing according to the real-time direction of sunlight throughout the day, and adjust the tilt angle of the solar panels on multiple photovoltaic tracking wings. The range of tilt angle changes can make the solar panels face the east, upward, and west. The photovoltaic tracking wings are connected to the main frame by a linkage with a drive device and are hinged together by a rotating shaft. It is flexible and the control device can independently control each photovoltaic tracking wing. The overall adjustability is high, making full use of sunlight and improving the light utilization rate.

[0018] The photovoltaic tracking wings increase the area of ​​the solar panels when the weather is sunny, and retract when the weather is bad or it gets dark, protecting the lifespan of the entire system and preventing the light box from being blown over in strong winds.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] A foldable photovoltaic tracking light box, such as Figure 1-5 As shown, the device includes a light box 1, a mounting frame 2, and a control device. The mounting frame 2 is located above the light box 1. The mounting frame 2 includes a main frame 3 and photovoltaic tracking wings 4. At least two photovoltaic tracking wings 4 are provided on the sides of the main frame 3. The inner side of the photovoltaic tracking wings 4 is connected to the main frame 3. The photovoltaic tracking wings 4 are connected to a drive device 5. The drive device 5 drives the outer end of the photovoltaic tracking wings 4 to swing up and down relative to the main frame 3 according to the direction of sunlight. The photovoltaic tracking wings 4 have at least two states: one is open relative to the main frame 3 to receive sunlight, and the other is folded down relative to the main frame 3. A top solar panel 31 is provided on the top of the main frame 3. A solar panel 6 is provided on the upper side of the photovoltaic tracking wings 4 when they are open relative to the main frame 3. When the photovoltaic tracking wings 4 are folded relative to the main frame 3, the solar panel 6 is located below the top solar panel 31.

[0029] In one implementation, the power supply box is a light-emitting light booth, which can further be an advertising light booth. The power supply box 1 contains a battery electrically connected to the solar panel 6. A light-transmitting panel 11 is provided on the side of the power supply box 1, and a lamp body 12 is installed inside the power supply box 1, which is electrically connected to the battery. The power supply box 1 has inner and outer layers 13 inside its shell. A rotating rod 14 for installing advertising cloth is located at the top of the inner and outer layers 13. The rotating rod 14 is connected to a motor that drives its rotation, and the motor is electrically connected to the battery. The battery supplies power to the motor, which drives the rotating rod 14 to rotate, allowing the advertising cloth to be rolled up and down. Alternatively, a vertical guide rail can be installed within the roller, and the motor drives a slider to rise and fall along the guide rails on both sides. The advertising cloth is connected to the slider, and the movement of the slider allows for insertion into or removal from the inner and outer layers 13. This eliminates the need for manual pasting and replacement of the advertising cloth, keeps the power supply box clean, and facilitates easy replacement of the advertising cloth.

[0030] In one implementation, the unfolded state can include an upward tilting state and a downward tilting state relative to the main frame 3. When the photovoltaic tracking wing 4 changes from the unfolded upward tilting state to the folded state, the flip angle is not less than 180°. The main frame 3 includes a side limiting part 32, and a corresponding number of photovoltaic tracking wings 4 are connected to the side of the main frame 3. When each photovoltaic tracking wing 4 is closed relative to the main frame 3, the inner surface of the photovoltaic tracking wing 4 is in contact with the corresponding side limiting part 32. The angle between the photovoltaic tracking wing 4 and the side limiting part 32 can be set to any angle between 0° and 270°. At 0°, the two are in a closed state. When flipped to 90-180°, the photovoltaic tracking wing 4 unfolds to a downward tilting position. After continuing to flip to greater than 180°, the photovoltaic tracking wing 4 unfolds to a upward tilting position. The flip angle can be arbitrarily set according to the direction of direct sunlight, such as 60°, 95°, 105°, 110°, 145°, or 225°, etc., which will not be elaborated here.

[0031] There are several control bases for the control device. One implementation method is time control, because the time conversion is relatively fixed. Each corresponding time controls the swing of the photovoltaic tracking wing 4, which means controlling the solar panels on the photovoltaic tracking wing 4 to receive direct sunlight as much as possible, improving battery utilization, and thus increasing power generation.

[0032] As another implementation method, such as Figure 6As shown, a light sensor 7 is provided on one side of the solar panel 6 of the photovoltaic tracking wing 4. The light sensor 7 includes a light-blocking partition 71, which is perpendicular to the surface of the solar panel 6. A light intensity sensor 1 72 and a light intensity sensor 2 73 are respectively provided on the left and right sides of the light-blocking partition 71. The light intensity sensor 1 72 and the light intensity sensor 2 73 are electrically connected to the control device. The light intensity sensor 1 72 and the light intensity sensor 2 73 respectively sense the light intensity and transmit the light signal to the control device. The control device drives each drive device 5 to rotate forward or backward according to the comparison of the light intensity on both sides until the light intensity sensed by the light intensity sensor 1 72 and the light intensity sensor 2 73 are consistent. If the light sensor 7 has a housing, it is made of a light-transmitting material. The light-blocking partition 71 blocks sunlight from the side. Since the light-blocking partition 71 is perpendicular to the surface of the solar panel 6, when the direction of sunlight is not perpendicular to the solar panel 6, one of the light intensity sensors, let's say light intensity sensor one 72, will be illuminated, while the other light intensity sensor two 73 will be blocked by the light-blocking partition 71. Therefore, the light intensity sensed by the two light intensity sensors will be weaker, resulting in a difference in the light intensity sensed by the two light intensity sensors. When the drive device 5 rotates clockwise or counterclockwise until the direction of sunlight is perpendicular to the solar panel 6, since neither side is blocked by the light-blocking partition 71, the light intensity sensed by light intensity sensor one 72 and light intensity sensor two 73 will be the same. The clockwise or counterclockwise rotation of the drive device 5 can be determined based on which side of the light intensity sensor is stronger. For example, it can rotate clockwise when light intensity sensor one 72 senses a higher light intensity, and counterclockwise when light intensity sensor two 73 senses a higher light intensity. This correlation can also be reversed. In addition, this method of sensing light intensity can be done in real time, with very accurate sensing and rapid feedback, which greatly improves the light utilization rate of solar panels.

[0033] The photovoltaic tracking wing 4 is connected to the main frame 3 via two hinged connecting rods 41. One end of one connecting rod 41 is hinged to the photovoltaic tracking wing 4, and the other connecting rod 41 is connected to the drive device 5 on the main frame 3. Due to the hinge of the two connecting rods, the drive device 5 drives one end of the connecting rod 41 to rotate, causing the other end to swing, which in turn causes the end of the connecting rod 41 connected to it to swing as well, thus causing the end connected to the photovoltaic tracking wing 4 to swing as well, thereby achieving fixed angle control.

[0034] A solar panel 6 is also installed on the upper surface of the top solar panel 31. Although the solar panel 6 on the top solar panel 31 cannot be folded up, as a part with a relatively large area that receives direct sunlight for a relatively long time, installing a solar panel 6 on the top solar panel 31 can increase the effective area for receiving sunlight to generate electricity and make full use of the top space of the photovoltaic tracking power generation light box.

[0035] Example 2

[0036] Same as in Example 1, such as Figure 1-2As shown, the difference is that the main frame 3 is a trapezoidal body with a larger top and a smaller bottom. There is a rectangular side limiting part 32 on each side of the main frame 3. The front and rear sides of the main frame 3 are inverted trapezoidal. A photovoltaic tracking wing 4 is connected to the outside of the side limiting part 32. The photovoltaic tracking wing 4 is also rectangular and matches the shape of the side limiting part 32.

[0037] Example 3

[0038] Same as in Example 1, such as Figure 4-5 As shown, the difference is that the main frame 3 is a quadrangular truncated pyramid with a larger top and a smaller bottom. The main frame 3 has an inverted trapezoidal side limiting part 32 on each of the front, back, left and right sides. The photovoltaic tracking wing 4 is connected to the outside of the side limiting part 32. The photovoltaic tracking wing 4 is also trapezoidal and its shape matches the shape of the side limiting part 32.
