[0019] The automatic light - increasing device for a sunlight - type plant factory provided by the present utility model is installed on the north wall of the sunlight - type plant factory, and includes a left side plate - 1, a right side plate - 2, a translation plate - 6, a limit block - 7, a reflector - 11, a support base - 12, and a support rod - 14.
[0020] The left side plate 1 and the right side plate 2 are arranged oppositely and installed on the north wall of the sunlight - type plant factory. A translation plate 6 is movably connected between the left side plate 1 and the right side plate 2. A first driving motor 5 is provided on the outer side surface of the right side plate 2. Two limit blocks 7 are oppositely arranged at both ends of one side surface of the translation plate 6. A support base 12 is movably connected between the two limit blocks 7. A second driving motor 10 is provided on the outer side surface of the limit block 7. One side of the support base 12 away from the north wall of the plant factory is connected to the reflector 11 through a support rod 14. Both the first driving motor 5 and the second driving motor 10 are electrically connected to a PLC (not shown in the figure), and the PLC is electrically connected to a light - chasing sensor (not shown in the figure).
[0021] It should be noted that one end of the left plate 1 is rotatably connected to one end of the right plate 2 through the first screw rod 3, and the other end of the left plate 1 is fixedly connected to the other end of the right plate 2 through the first sliding rod 4. One end of the translation plate 6 is screwed onto the first screw rod 3, and the other end is slidably sleeved on the first sliding rod 4. One end of the first screw rod 3 penetrates through the right plate 2 and is connected to the output shaft of the first driving motor 5. By driving the first screw rod 3 to rotate through the first driving motor 5, the translation plate 6 is enabled to horizontally move along the axial directions of the first screw rod 3 and the first sliding rod 4.
[0022] It should be noted that a second sliding rod 9 and a rotatably connected second screw rod 8 are provided between the two limiting blocks 7. One end of the support seat 12 is slidably sleeved on the second sliding rod 9 and the other end is threadedly connected to the second screw rod 8. One end of the second screw rod 8 penetrating through the limiting block 7 is connected to the output shaft of the second driving motor 10. By driving the second screw rod 8 to rotate through the second motor 10, the support seat 12 is enabled to vertically move along the axial directions of the second screw rod 8 and the second sliding rod 9.
[0023] To further optimize the above solution, the support rod 14 is hinged to the support seat 12. A third driving motor 13 electrically connected to the PLC is provided on the top surface of the support seat 12. The hinge axis of the support rod 14 and the support seat 12 is fixedly connected to the output shaft of the third driving motor 13. By driving the support rod 14 to rotate around the output shaft of the third driving motor 13 in the horizontal plane through the third driving motor 13, the reflector 11 is driven to rotate around the output shaft of the third driving motor 13 in the horizontal plane.
[0024] To further optimize the above solution, the support rod 14 is hinged to the reflector 11. A fourth driving motor 15 electrically connected to the PLC is provided on one side of the reflector 11 close to the north wall of the plant factory.

By driving the reflector 11 to rotate around the output shaft of the fourth driving motor 15 in the vertical plane through the fourth driving motor 15.
[0025] It should be noted that the first driving motor - 5, the second driving motor - 10, the third driving motor - 13, and the fourth driving motor - 15 directly or indirectly drive the reflector to achieve four - degree - of - freedom motions such as horizontal movement, vertical movement, rotation in the horizontal plane, and rotation in the vertical plane, so as to reflect the sunlight at different times onto the vegetable planting layer that needs to be supplemented with light, ensuring uniform lighting of the vegetables and promoting the growth of the vegetables.
[0026] Specifically, several automatic light-increasing devices are arranged on the wall at the north end of each picking passage. The reflecting mirror 11 can be fixed on the support rod 14 through a metal frame. The light-tracking sensor tracks the movement of the sun and transmits signals to the PLC. The PLC adjusts the position and reflection angle of the reflecting mirror through a driving motor to increase the light on the vegetables on each layer of the planting bed. The adjustment principle is as follows: 1. Sensor detection: The light-tracking sensor can detect the position of the sun and the direction of the light. These sensors can include optical fiber sensors, GPS positioning systems, or solar tracking algorithms, etc.; 2. Data processing: The solar position data collected by the sensors is transmitted to the PLC, and the PLC processes and analyzes the data to determine the position and movement trajectory of the sun in the sky; 3. Mechanical adjustment: According to the calculation results of the PLC, the PLC automatically adjusts the horizontal and vertical positions of the reflecting mirror (corresponding to forming an (x, y) coordinate), as well as the rotation in the up-down and left-right directions, driving the reflecting mirror to adjust the position and reflection angle, so that the reflected sunlight always shines on the vegetable planting layer that needs light-increasing on the planting bed. In addition, the rotation principle of the photovoltaic panel can also be used for control, which will not be elaborated here.
[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
