Technical Field

[0001] This utility model belongs to the field of fruit quality improvement technology, specifically relating to a solar supplementary lighting device for grape cultivation. Background Technology

[0002] Grapes are juicy and tender, rich in anthocyanins and other antioxidants, which are beneficial to human health. Grapes are light-loving plants, and the coloring of grape fruit and the accumulation of anthocyanins are significantly affected by light. A reasonable spectrum of light composition, suitable light duration and intensity are conducive to the synthesis of phenolic substances such as anthocyanins in grape fruit, thereby improving fruit quality and increasing its economic value.

[0003] my country ranks first in the world in both the area and yield of greenhouse grape cultivation, making it an important way to increase rural economic benefits. However, greenhouse cultivation methods, such as those using polytunnels and rain shelters, often result in insufficient and uneven light exposure on the fruit surface, hindering fruit coloring, reducing fruit quality, and ultimately lowering economic returns. Furthermore, existing supplemental lighting techniques often involve installing lights around the vine, which can increase light exposure to the fruit to some extent. However, large-scale supplemental lighting can also interfere with normal photosynthesis in the leaves, thus affecting vine growth and increasing energy consumption costs. Utility Model Content

[0007] In a tee, the angle between the two straight pipes is 60°, and the angle between the main pipe and the straight pipe is 90°.

[0008] Both the horizontal and vertical connecting columns are hollow aluminum tubes with an outer diameter of 3mm.

[0009] The length of the straight pipe in the tee and the main pipe is both 10mm.

[0010] The side length of the triangular bracket is 200mm, and the length of the vertical connecting column is 250mm.

[0019] like Figures 2-4 As shown, the supplementary lighting unit 4 includes a triangular prism support frame 41 and three sets of LED flexible light strips 42. The triangular prism support frame 41 includes two triangular supports 44 and three vertical connecting columns 45 located between the two triangular supports 44. The top and bottom of the vertical connecting columns 45 are respectively fixedly connected to one of the triangular supports 44. The LED flexible light strips 42 are fixedly installed on the vertical connecting columns 45 and aligned with the grape bunches 5 located inside the triangular prism support frame 41.

[0020] like Figure 5 As shown, in this embodiment, the output terminal of the solar panel 1 is connected to the battery pack 2 via a photovoltaic charging controller, which charges the battery pack 2 under the control of the photovoltaic charging controller. The output terminal of the battery pack 2 is connected to a DC-DC voltage conversion unit 3, and the output terminal of the DC-DC voltage conversion unit 3 is electrically connected to the LED flexible lamps 42 in each supplementary lighting unit 4 via a cable 6. All circuit components are connected via cables 6. Specifically, the solar panel 1 uses a 36V output solar panel, and the photovoltaic charging controller outputs 24V to charge the battery pack 2. The output voltage of the battery pack 2 is 24V, which is converted to 12V by the DC-DC voltage conversion unit 3 to power the LED flexible lamp strips 42. Specifically, in this embodiment, the DC-DC voltage conversion unit 3 is model HS-200F24V, with an input voltage of 24V and an output voltage of 12V.

[0021] Furthermore, such as Figure 5 As shown, a solar supplemental lighting device for grape cultivation in this embodiment further includes a supplemental lighting time adjustment unit 9. The supplemental lighting time adjustment unit 9 is disposed between the battery pack and the DC voltage conversion unit 3, and is used to set the on-time of the LED flexible light strip 42.

[0022] Furthermore, in this embodiment, the triangular bracket 44 includes three horizontal connecting columns 46 and three tees 47. The three horizontal connecting columns 46 are connected to each other through a tee 47. The two straight pipes 471 of the tee 47 are used to connect to a horizontal connecting column 46, and the main pipe 472 is used to connect to the vertical connecting column 45.

[0023] Furthermore, such as Figure 6 As shown, in the tee 47 of this embodiment, the included angle between the two straight pipes 471 is 60°, and the included angle between the main pipe 472 and the straight pipe 471 is 90°.

[0024] Furthermore, in this embodiment, both the horizontal connecting column 46 and the vertical connecting column 45 are hollow aluminum tubes with an outer diameter of 3mm.

Furthermore, since the grape bunches grow in the middle of the new shoots of the vine, near the second wire of the grape trellis, the supplementary lighting unit 4 is fixed at the new shoot of the vine near the second wire of the grape trellis. During installation, the position of the supplementary lighting unit 4 is adjusted so that the grape bunches are placed in the center of the triangular prism support frame 41.
