Abstract
Description
Technical Field
[0001] This utility model relates to the field of supplemental lighting technology for agricultural greenhouses, and in particular to a supplemental lighting device for agricultural planting. Background Technology
[0002] During periods of low light conditions in agricultural greenhouses, supplemental lighting devices are needed to ensure the normal growth of agricultural plants. Existing supplemental lighting devices generally use LED full-spectrum plant growth lights, which are typically round. For usage instructions, please refer to... Figure 6 The supplementary lights 2 need to be suspended on the frame 1 at the top of the agricultural greenhouse. Because the frame 1 has large gaps, and the light and shadow projected by the supplementary lights 2 are roughly circular, weak light zones 4 will appear between the four adjacent supplementary lights 2. These weak light zones 4 may not meet the optimal photosynthetic needs of the agricultural plants, leading to reduced photosynthetic efficiency and affecting their growth and development. For example, the plants may become weak, the leaves may not be as green, and the flowering and fruiting time may be delayed. To solve this problem, another supplementary light 2 could be installed within the weak light zone 4, but this area lacks a frame 1, making installation of the supplementary light 2 inconvenient.
[0003] In the prior art, to solve this problem, CN209330667U, published on September 3, 2019, discloses a supplementary lighting system for changing the light intensity of a greenhouse. The system includes a greenhouse support frame, a lighting component mounted on top of the support frame, and a base and supplementary light lamp. The base is fixedly mounted on the greenhouse support frame, and the supplementary light lamp is fixed to the base via an angle adjustment device. The angle adjustment device includes a telescopic rod mounted on the base, a mounting plate at the bottom of the telescopic rod, a first drive mechanism for driving the supplementary light lamp to rotate horizontally on the mounting plate, a support frame at the bottom of the first drive mechanism, bearing holes on both sides of the support frame, a swing shaft rotatably mounted within the bearing holes, and a second drive mechanism for driving the supplementary light lamp to tilt and rotate at one end of the swing shaft. The supplementary light lamp is mounted on the swing shaft. Its features are: the supplementary light lamp works in concert with the first and second drive mechanisms to adjust the illumination angle of the supplementary light lamp, so that the entire greenhouse is within the illumination range of the supplementary light lamp, so as to achieve supplementary lighting without dead angles; its disadvantages are that the adjustment of the illumination position of the supplementary light lamp requires two motors and a telescopic rod, which increases the cost of use, and the increased electrical equipment increases the difficulty of control.

[0035] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0036] Example 1:
[0037] Please see Figure 1-3An agricultural supplemental lighting device includes a lamp holder 10, which has a rectangular structure. The bottom of the lamp holder 10 has a light groove 11, wider at the bottom than the top. A first supplemental light 12 is installed at the top of the light groove 11. Second supplemental lights 16 are installed on the four sides of the lamp holder 10. An extension 18 is provided at the top of the lamp holder 10, with the second supplemental lights 16 located below the extension 18. First reflectors 20 are installed on the extension 18 corresponding to the positions of the four second supplemental lights 16. This invention expands the supplemental lighting range, eliminates weak light areas, and improves the supplemental lighting effect by installing second supplemental lights 16 on the four sides of the lamp holder 10 and installing first reflectors 20 on the extension 18 corresponding to the positions of the second supplemental lights 16. Figure 7 As shown, it is easy to adjust and control.
[0038] The light trough 11 can be in the shape of a frustum or a square pyramid. In this embodiment, the light trough 11 is preferably in the shape of a square pyramid, and the first supplementary light 12 is installed at the top of the light trough 11, that is, at the small end of the light trough 11.
[0039] The first reflector 20 uses existing technology, such as a plastic sheet coated with a reflective coating or a smooth aluminum sheet.
[0040] Example 2:
[0041] Based on Example 1, see Figure 3 The angle between the first reflector 20 and the second supplementary light 16 can be adjusted. This allows the first reflector 20 to be adjusted according to the gap between the frames 1, thereby adjusting the illumination range and eliminating weak lighting areas.
[0042] In one embodiment, the edge of the protrusion 18 has two first ear brackets 19 at positions corresponding to each of the second supplementary lights 16. A second ear bracket 21 is provided on the lower side of the first reflector 20 at a position corresponding to the first ear bracket 19. The first ear brackets 19 and the second ear brackets 21 are connected by fasteners 23. In this embodiment, the fasteners 23 are bolts. Loosening the fasteners 23 allows adjustment of the first reflector 20; after adjustment, the fasteners 23 are tightened to secure it.
[0043] Example 3:
[0044] Based on Example 2, see Figure 3 Fastener 23 is a hinge pin.
[0045] The first reflector 20 is provided with an extension rod 22 at one end of the second ear seat 21. The extension rod 22 is connected to the adjustment structure 50 to control the adjustment angle of the first reflector 20 and realize the synchronous adjustment of the angles of the four first reflectors 20.
[0046] Furthermore, the adjustment structure 50 includes a connecting rod 55 and a driving device for driving the connecting rod 55 to move up and down. The extension rods 22 of the four first reflectors 20 are respectively connected to the four connecting rods 55. One end of the connecting rod 55 is connected to the driving device, and the other end of the connecting rod 55 is provided with a transverse elongated hole 552. The extension rod 22 is slidably connected to the elongated hole 552 through a hinge pin 24.
[0047] Specifically, the other end of the connecting rod 55 is provided with a notch 551 in the longitudinal direction, the elongated hole 552 passes through the notch 551, the extension rod 22 extends into the notch 551, and the extension rod 22 is slidably connected to the elongated hole 552 through the hinge pin 24.
[0048] In this embodiment, the driving device can be an electric cylinder, which can be installed on the top of the lamp holder 10. The connecting rod 55 is fixedly connected to the telescopic end of the electric cylinder to achieve electric synchronous adjustment.
[0049] In this embodiment, as Figure 3 As shown, connecting rod 55 is Z-shaped.
[0050] Example 4:
[0051] The difference from Example 3 is that, see below... Figure 3 A connecting cylinder 30 is installed on the top of the lamp holder 10. A cylinder cover 301 is installed on the top of the connecting cylinder 30. An installation part 40 is fixedly connected to the top of the cylinder cover 301. The installation part 40 facilitates installation and fixation with the frame 1.
[0052] Specifically, the mounting component 40 includes a fixed ring 41 and a movable ring 42. The fixed ring 41 is fixedly mounted on the cylinder cover 301, and the movable ring 42 is detachably mounted on the fixed ring 41 by bolts.
[0053] Furthermore, the drive device is installed inside the connecting cylinder 30. The drive device includes a lead screw 51, a worm gear 52, a lifting plate 53, a worm 54, and an adjusting device 56. The lead screw 51 is longitudinally rotatably installed inside the connecting cylinder 30. The lifting plate 53 is threadedly connected to the lead screw 51. The end of the connecting rod 55 connected to the drive device passes through the longitudinal hole 35 on the connecting cylinder 30 and then connects to the lifting plate 53. The worm gear 52 is fixedly installed on the lead screw 51. The worm 54 is rotatably installed on the support seat 34 inside the connecting cylinder 30. The worm 54 meshes with the worm gear 52. The adjusting device 56 is connected to the worm 54 for transmission to drive the worm 54 to rotate.
[0054] Specifically, the upper and lower ends of the lead screw 51 are rotatably connected to the lamp holder 10 and the cylinder cover 301 respectively via bearings 331. The worm gear 54 is driven by the adjusting device 56. The rotation of the worm gear 54 drives the worm wheel 52 to rotate, and the rotation of the worm wheel 52 drives the lead screw 51 to rotate, thereby causing the lifting plate 53 to move up and down along the lead screw 51. When the lifting plate 53 moves downward, the driving link 55 moves downward, thereby causing the first reflector 20 to open outward and increase the illumination area. When the lifting plate 53 moves upward, the driving link 55 moves upward, thereby causing the first reflector 20 to close inward under the action of gravity and reduce the illumination area.
[0055] In this embodiment, the adjusting device 56 may be a motor.
[0056] In the preferred embodiment, see Figure 3 The adjusting device 56 includes an extension rod 561 and a handwheel 562. The extension rod 561 is fixedly connected to the handwheel 562. One end of the worm gear 54 is provided with a limit hole, and the connecting cylinder 30 is provided with a clearance hole at the corresponding position of the limit hole. The extension rod 561 passes through the clearance hole and then connects with the limit hole of the worm gear 54 for transmission. When adjustment is required, the extension rod 561 is inserted into the limit hole at one end of the worm gear 54. The limit hole can be a polygonal hole, and the extension rod 561 is a matching polygonal rod.
[0057] In this embodiment, the end of the connecting rod 55 connected to the drive device can be welded and fixed to the lifting plate 53 after passing through the longitudinal hole 35 on the connecting cylinder 30. Alternatively, a connecting groove 531 can be provided on the lifting plate 53 at the position corresponding to the connecting rod 55. The end of the connecting rod 55 connected to the drive device can be inserted into the connecting groove 531 after passing through the longitudinal hole 35 on the connecting cylinder 30, and connected to the lifting plate 53 by a fastener. When the fastener is a hinged pin, since the connecting rod 55 has many degrees of freedom, a guide seat 36 can also be provided on the outer wall of the connecting cylinder 30. The connecting rod 55 is slidably connected to the guide seat 36, so that the connecting rod 55 can only slide up and down.
[0058] Example 5:
[0059] Based on Example 4, see Figure 3 A support ring 32 is provided in the middle of the inner wall of the connecting cylinder 30. A partition 33 is detachably installed on the support ring 32. The driving device is located on the upper side of the partition 33, and an LED driver 60 is installed on the lower side of the partition. The first supplementary light 12 and the second supplementary light 16 are both LED light boards. The LED driver 60 is electrically connected to the first supplementary light 12 and the second supplementary light 16, respectively. Through the above structure, the LED driver 60 and the driving device are both installed inside the connecting cylinder 30, resulting in higher integration. The connecting cylinder 30 can be installed on the support ring 32 with screws or snapped onto the support ring 32.
[0060] Example 6:
[0061] Based on embodiments 1 to 5, second reflectors 13 are respectively installed on the four inclined walls inside the lamp trough 11, and a first light-transmitting plate 14 is installed at the bottom of the lamp holder 10. The second reflectors 13 improve the reflection effect, and the first light-transmitting plate 14 evens out the light and protects the first supplementary light 12.
[0062] Furthermore, mounting slots 15 are provided on the four sides of the lamp holder 10, and the second supplementary light 16 is installed in the mounting slot 15. A second light-transmitting plate 17 is installed at the open end of the mounting slot 15. The second light-transmitting plate 17 evenly distributes the light and protects the second supplementary light 16.
[0063] The second reflector 13, the first light-transmitting plate 14, and the second light-transmitting plate 17 can be installed by adhesive or bolt connection.
[0064] The working principle or operation process of this utility model is as follows:
[0065] See Figure 3 The device is fixedly mounted on the frame 1 by the mounting piece 40, and the LED driver 60 is connected to the power supply via a wire. When adjusting the illumination range, the adjustment device 56 is inserted into the worm gear 54, thereby driving the worm gear 54 to rotate. The rotation of the worm gear 54 drives the worm wheel 52 to rotate, which in turn drives the lead screw 51 to rotate, thereby causing the lifting plate 53 to move up and down along the lead screw 51. When the lifting plate 53 moves downward, the driving link 55 moves downward, causing the first reflector 20 to open outward, increasing the illumination area; when the lifting plate 53 moves upward, the driving link 55 moves upward, causing the first reflector 20 to close inward under the action of gravity, reducing the illumination area. Figure 7 As shown.
