Description

Technical Field

[0001] This utility model relates to the field of greenhouse light regulation technology, and in particular to a light regulation device for daylily cultivation greenhouses. Background Technology

[0002] In the field of daylily cultivation, light is a key factor affecting its growth, development, yield, and quality. Daylilies at different growth stages have significantly different requirements for light intensity, duration, and location. For example, seedlings need gentle and uniform light to promote root development, while flowering requires sufficient direct sunlight to ensure flower bud differentiation and full fruit. As a controllable cultivation environment, greenhouses need specialized light regulation devices to meet the light requirements of daylilies at each stage.

[0003] In existing technologies, light regulation in daylily greenhouses mostly employs fixed supplemental lighting mechanisms. The mechanical structure primarily includes a fixed support frame installed on the greenhouse roof, supplemental lights evenly distributed on the frame, and a simple switch control device. The supplemental lights are typically fluorescent or incandescent lamps, fixed at specific locations on the greenhouse roof by the support frame, maintaining a fixed distance from the ground. The technical principle is that when natural light is insufficient, the supplemental lights provide additional illumination to the daylilies inside the greenhouse. The fixed angle of the light covers a certain area to meet basic photosynthetic needs. This structure achieves large-area illumination coverage through fixed-installation lighting fixtures, is simple to operate, and has low cost.

[0004] However, existing fixed supplemental lighting mechanisms, due to the fixed position and angle of the supplemental lights, make it difficult to adjust the light position according to the plant height and growth status of daylilies at different growth stages. For example, when daylilies enter the flowering stage from the seedling stage, the plant height increases significantly, and the light that was originally illuminating the area near the roots of the seedlings can hardly effectively cover the upper flower stems and flower buds, resulting in insufficient light in key growth areas, affecting flower bud development and flowering and fruiting. This makes it difficult to meet the specific light position requirements of daylilies at different growth stages, thus restricting the improvement of daylily yield and quality. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a light regulation device for daylily greenhouses, which aims to improve the problem of timely adjustment of light irradiation position according to the plant height and growth status of daylilies at different growth stages.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a light adjustment device for a daylily planting greenhouse, comprising a support frame 1, a connecting plate 1 fixedly connected to the outer wall of the support frame 1, an adjustment component provided on the inner wall of the connecting plate 1, a support frame 2 provided on the upper surface of the support frame 1, a shade net provided on the outer wall of the support frame 2, and a connecting plate 2 fixedly connected to the outer wall of the support frame 1.

[0007] The adjustment assembly includes a sliding rod, the outer wall of which is fixedly connected to the inner wall of a connecting plate. A limit groove is formed inside the sliding rod. A sliding block is slidably connected to the outer wall of the sliding rod. A fixing plate is fixedly connected to the inner wall of the sliding block.

[0008] Furthermore, a protective cover is fixedly connected to the outer wall of the second connecting plate, and a connecting shaft and a connecting shaft are provided on the inner wall of the first protective cover. A turntable is fixedly connected to the outer wall of the first connecting shaft.

[0009] Furthermore, gear one and gear two are fixedly connected to the outer walls of connecting shaft one and connecting shaft two, respectively, and gear one and gear two are meshed with each other.

[0010] Furthermore, a sliding rod is fixedly connected to the inner wall of the protective cover, and a rack is slidably connected to the outer wall of the sliding rod, with the rack and gear meshing with each other.

[0011] Furthermore, a sliding groove 2 is provided inside the first protective cover, and a second protective cover is fixedly connected to the outer wall of the first protective cover, and a sliding groove 1 is provided inside the second protective cover.

[0012] Furthermore, a connecting shaft three is rotatably connected to the inner wall of the second protective cover, and a gear three is fixedly connected to the outer wall of the third connecting shaft three, with the gear three meshing with the rack.

[0013] Furthermore, a connecting rod is slidably connected to the inner wall of the second protective cover, a rotating shaft is rotatably connected to the inner wall of the first connecting rod, a connecting rod is rotatably connected to the outer wall of the second rotating shaft, a rotating shaft is rotatably connected to the inner wall of the second connecting rod, and the outer wall of the third rotating shaft is fixedly connected to the inner wall of the second bracket.

[0014] Furthermore, a pivot is fixedly connected to the inner wall of the first bracket, and a pivot is rotatably connected to the inner wall of the second bracket.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, by pressing down on the pressing block, the inclined block two slides along the inner wall of the sliding block, the spring deforms and stores energy, driving the inclined block one and the T-shaped limiting block to move upward. Sliding the pressing block allows the limiting block to adjust its position in the sliding groove. After releasing, the spring pushes the component to reset, causing the T-shaped crossbar of the limiting block to engage with the sliding groove and complete the fixation. The entire operation only requires pressing, sliding, and releasing to achieve flexible adjustment and stable fixation of the lamp position. The operation is simple and labor-saving, and the adjustment is precise. It can accurately control the light range and intensity according to the growth needs of daylilies, providing them with a suitable light environment.

[0017] In this invention, rotating the turntable drives the connecting shaft to rotate, which in turn drives the gear to rotate. Through gear meshing, the gears 2, rack, and gear 3 are linked in sequence. Finally, through the coordinated action of the connecting rod and the rotating shaft, the support 2 is pushed out, thus adjusting the angle of the shading net to block sunlight. This gear and rack meshing transmission combined with the connecting rod linkage structure provides precise and stable transmission. The shading net can be adjusted simply by rotating the turntable, which can quickly respond to changes in light intensity and flexibly control the degree of shading in the greenhouse, avoiding the impact of strong light on the growth of daylilies and ensuring the stability of their growing environment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-4 This utility model provides an embodiment of a daylily greenhouse light regulation device, including a support frame 2. The support frame 2 integrates the components into a stable whole through fixedly connected components such as a connecting plate 5 and a support frame 3, ensuring the firmness of the light regulation device in the greenhouse.

[0027] The adjustment assembly includes a sliding rod 6, which provides a sliding track for a sliding block 7. The sliding rod 6 is fixed in position by a connecting plate 5, allowing the sliding block 7 to slide stably along its outer wall, thereby adjusting the position of the lamp 8 and providing basic guidance for illumination adjustment. The outer wall of the sliding rod 6 is fixedly connected to the inner wall of the connecting plate 5. A limiting groove 11 is formed inside the sliding rod 6, providing a locking position for a limiting block 12. Different positions of the limiting groove 11 correspond to different positions of the lamp 8. When the limiting block 12 engages, it can fix the lamp 8, ensuring the stability of the adjusted illumination position. The sliding block 7 is slidably connected to the outer wall of the sliding rod 6. The sliding block 7 slides in conjunction with the sliding rod 6. When the sliding block 7 slides along the outer wall of the sliding rod 6, it can drive the lamp 8 to move synchronously, thereby adjusting the illumination range. Simultaneously, its inner wall provides installation space for components such as the fixing plate 9 and the inclined block. The fixing plate 9 is slidably connected to the inner wall of the sliding block 7. The fixing plate 9 is used to fix the spring 10. Through its slidable connection with the sliding block 7, it provides stable support for the spring 10 and the inclined block 14, ensuring that the spring 10 remains stable during deformation and reset, thus guaranteeing the reliability of the adjustment action. The spring 10 is fixedly connected to the outer wall of the fixing plate 9, and the spring 10, in conjunction with the inclined block 14, performs elastic reset. When the pressing block 15 is pressed, the spring 10 is compressed and deformed to store energy. After the pressing block 15 is released, the spring 10 releases energy to push the second inclined block 14 back to its original position, which in turn drives the first inclined block 13 and the limiting block 12 to return to their original positions, thus realizing the automatic locking of the lamp 8. One end of the spring 10 is fixedly connected to the second inclined block 14, which cooperates with the first inclined block 13 for sliding transmission. When the second inclined block 14 slides along the inner wall of the sliding block 7, it pushes the first inclined block 13 upward through the inclined surface, thereby driving the limiting block 12 to disengage from the limiting groove 11. The outer wall of the second inclined block 14 is slidably connected to the first inclined block 13, and the second inclined block 14 cooperates with the first inclined block 13 for sliding transmission.

The outer wall of the first inclined block 13 is fixedly connected to the limiting block 12. The limiting block 12 engages with the limiting groove 11 for fixation. Its T-shaped crossbar can be inserted into the limiting groove 11 to fix the sliding block 7 and the first sliding rod 6 relative to each other, thereby locking the position of the lamp 8. When the limiting block 12 moves upward and disengages from the limiting groove 11, the sliding block 7 can slide and adjust freely to ensure accurate adjustment of the lighting position. The outer wall of the second inclined block 14 is fixedly connected to the pressing block 15, and the outer wall of the sliding block 7 is fixedly connected to the lamp 8.

[0028] Specifically, the adjustment assembly includes a sliding rod 6, the outer wall of which is fixed to the inner wall of the connecting plate 5, providing a sliding track for the sliding block 7. An internal limiting groove 11 provides a locking position for the limiting block 12. Different positions of the limiting groove 11 correspond to different positions of the lamp 8. When locked in, the lamp 8 is fixed. The outer wall of the sliding rod 6 is slidably connected to the sliding block 7. As the sliding block 7 slides along the rod, it moves the lamp 8 to adjust the illumination range. The inner wall is slidably connected to a fixing plate 9, which is used to fix the spring 10. The spring 10 fixed to its outer wall cooperates with the inclined block 14 for elastic reset movement. When the pressing block 15 is pressed, the spring 10 is compressed and deformed to store energy. When released, the energy is released to push the second inclined block 14 to reset. The outer wall of the second inclined block 14 is slidably connected to the first inclined block 13. The two cooperate to slide and drive. When the second inclined block 14 slides, it pushes the first inclined block 13 upward through the inclined surface, which drives the limit block 12 to disengage from the limit groove 11. The limit block 12 fixed on the outer wall of the first inclined block 13 is engaged and fixed with the limit groove 11. When the T-shaped horizontal bar is engaged, it fixes the sliding block 7 and the first sliding rod 6. When it moves upward and disengages, the sliding block 7 can slide freely. The pressing block 15 is fixed on the outer wall of the second inclined block 14, and the lamp 8 is fixed on the outer wall of the sliding block 7.

[0029] Reference Figures 1-5A protective cover 18 is fixedly connected to the outer wall of connecting plate 2 32.

Simultaneously, it changes the transmission direction, ensuring that the power can effectively drive rack 23. A sliding rod 22 is fixedly connected to the inner wall of protective cover 18. The sliding rod 22 is fixed to protective cover 18, ensuring that rack 23 can only move smoothly in a straight line. Rack 23 is slidably connected to the outer wall of sliding rod 22. Rack 23 engages with Gear 3 25 for transmission. When rack 23 slides, it drives Gear 3 25 to rotate, converting linear motion back into rotational motion, thus achieving secondary power transmission. The direction changes, with rack 23 and gear 20 meshing together. A sliding groove 23 is provided inside protective cover 18, and protective cover 26 is fixedly connected to the outer wall of protective cover 18. A sliding groove 31 is provided inside protective cover 26, allowing connecting rod 27 to rotate at a large angle, providing a flexible range of motion. A connecting shaft 34 is rotatably connected to the inner wall of protective cover 26, and gear 35 is fixedly connected to the outer wall of connecting shaft 34. Gear 35 and rack 23 mesh together. Connecting rod 27 is slidably connected to the inner wall of protective cover 26, sliding along sliding groove 31 under the drive of gear 35. Simultaneously, the movement is assisted by rotating shaft 23. 8 drives the movement of connecting rod 29, converting rotational motion into the swing of the connecting rod, providing power for the lifting and lowering of bracket 23. A rotating shaft 28 is rotatably connected to the inner wall of connecting rod 27. Rotating shaft 28, in conjunction with connecting rod 29, allows connecting rod 27 and connecting rod 29 to rotate flexibly, enabling force transmission and angle adjustment. Connecting rod 29 is rotatably connected to the outer wall of rotating shaft 28. Connecting rod 29, in conjunction with rotating shaft 30, transmits motion to bracket 23 via rotating shaft 30.

Pivot 4 is rotatably connected to the inner wall of bracket 23.

[0030] Specifically, the outer wall of the connecting plate 2 32 is fixed with a protective cover 18, the inner wall of which has a connecting shaft 19 and a connecting shaft 21. The connecting shaft 19 transmits the rotational motion of the turntable 16 to the gear 17. The connecting shaft 21 and the connecting shaft 3 24 provide rotation base points for gears 20 and 35, respectively. The outer wall of the connecting shaft 19 is fixed with the turntable 16. The operator can drive the connecting shaft 19 to rotate by rotating the turntable 16. The outer walls of the connecting shaft 19 and the connecting shaft 2 21 are respectively fixed with gears 17 and 20. The two mesh and transmit power. The rotation of gear 17 drives the rotation of gear 20, transmitting power and changing direction. The inner wall of the protective cover 18 is fixed with a sliding rod 22, the outer wall of which is slidably connected to a rack 23. The rack 23 meshes with gear 20 and also with gear 3 25. The meshing transmission involves the rack 23 sliding to drive the gear 3 25 to rotate, achieving secondary power transmission and direction conversion. The protective cover 18 has a sliding groove 2 33 inside, and the outer wall is fixed to the protective cover 26. The protective cover 26 has a sliding groove 31 inside, which allows the connecting rod 1 27 to slide. The inner wall of the protective cover 26 is rotatably connected to the connecting shaft 3 24, and the outer wall is fixed to the gear 3 25. The inner wall of the connecting rod 1 27 is rotatably connected to the rotating shaft 2 28, and the outer wall is rotatably connected to the connecting rod 2 29. When the connecting rod 1 27 slides along the sliding groove 31, it drives the connecting rod 2 29 to move through the rotating shaft 2 28. The inner wall of the connecting rod 2 29 is rotatably connected to the rotating shaft 3 30, and its outer wall is fixed to the inner wall of the bracket 2 3. The connecting rod 2 29 drives the bracket 2 3 to rotate around the rotating shaft 4 on the inner wall of the bracket 1 2 through the rotating shaft 3 30, thereby realizing the raising and lowering of the bracket 2 3 and adjusting the position of the sunshade net 1.

[0031] Working principle: When it is necessary to adjust the light in the daylily greenhouse, firstly, by pressing the pressing block 15, the outer inclined block 14 slides along the inner wall of the sliding block 7. At the same time, the spring 10 is deformed and stores energy. During this process, the inclined block 13 moves upward due to the sliding action of the inclined block 14, which drives the T-shaped limiting block 12 to move upward synchronously. Then, the pressing block 15 is slid, so that the limiting block 12 slides in the limiting groove 11 opened in the sliding rod 6. When the position is adjusted to a suitable position, the pressing block 15 is released, the spring 10 releases energy to push the inclined block 14 to reset, and the inclined block 13 and the limiting block 12 are restored. Finally, the T-shaped crossbar part of the limiting block 12 is inserted into the sliding groove, completing the fixation of the lamp 8 position and realizing the light adjustment function.

[0032] Secondly, when it is necessary to adjust the shade net 1 to block sunlight, the connecting shaft 19 is rotated by rotating the turntable 16, which in turn drives the gear 17 to rotate. Since the gear 17 meshes with the gear 20, the gear 20 rotates accordingly. The gear 20 meshes with the rack 23, causing the rack 23 to slide along the sliding rod 22 and the sliding groove 33. During the sliding process of the rack 23, it meshes with the gear 35, causing the gear 35 to rotate through the connecting shaft 34. The rotation of the gear 35 drives the connecting rod 27 to slide in the sliding groove 31 of the protective cover 26. The connecting rod 27, through the linkage of the rotating shaft 28, the connecting rod 29, and the rotating shaft 30, finally pushes the bracket 23 upward.
