Description
Technical Field
[0001] This utility model relates to the technical field of greenhouse supplemental lighting devices, and in particular to a light adjustment device for flower cultivation greenhouses. Background Technology
[0002] With the development of greenhouse flower cultivation technology, flowers can grow in a relatively controlled environment. Greenhouses can, to some extent, resist the effects of harsh weather and seasonal changes. However, even in a greenhouse environment, the problem of light still exists. The simple greenhouse structure only serves as a physical barrier and insulation, and cannot effectively regulate light.
[0003] In traditional flower cultivation, flowers primarily rely on natural light. However, natural light is subject to many uncontrollable factors, and seasonal changes can lead to significant differences in the duration and intensity of sunlight. In winter, the days are short and the light intensity is relatively weak, which is a serious limiting factor for some flower varieties that require longer periods of light and higher light intensity to grow and bloom normally.
[0004] Therefore, it is necessary to design a new type of light regulation device for flower cultivation greenhouses, which can adjust the light intensity by adjusting the area of the shading cloth that is pulled out. Utility Model Content
[0005] To address the aforementioned problems, this utility model proposes a light adjustment device for flower cultivation greenhouses.
[0006] This utility model is achieved through the following technical solution:
[0007] This utility model proposes a light adjustment device for a flower cultivation greenhouse, including a greenhouse body and a horizontal shading component and a vertical shading component installed inside the greenhouse body. The vertical shading component includes two rack shafts, and a movable roller is slidably connected between the two rack shafts. A first roller is rotatably connected to the lower inner side of the movable roller, and a pull-down shading cloth is fixedly connected to the first roller.
[0008] The transverse light-blocking assembly includes two rollers, both of which are rotatably connected to the top of a movable roller. A transverse light-blocking cloth is fixedly connected to the outside of each of the two rollers, and a movable crossbar is fixedly connected to the end of the transverse light-blocking cloth.
[0009] Furthermore, a rack is fixedly connected to the bottom of one side of the rack shaft, a motor is installed inside one side of the moving roller, and a gear is fixedly connected to the output end of the motor, the gear meshing with the rack.
[0010] Furthermore, spring plates are fixedly connected to both sides of the first roll, and the ends of the two spring plates away from the first roll are fixedly connected to the inner wall of the moving roller, and the pull-down light-blocking cloth is rolled on the outside of the first roll.
[0011] Furthermore, supplementary lights are installed on both sides of the moving roller.
[0012] Furthermore, a ratchet is fixedly connected to one side of the first scroll, a pull rod is slidably connected to the outside of the moving roller, a connecting block is fixedly connected to the end of the pull rod near the ratchet, a pawl is rotatably connected inside the connecting block, the pawl meshes with the ratchet, a second spring is sleeved on the outside of the pull rod, and a pull rope is fixedly connected to the end of the pull rod away from the connecting block.
[0013] Furthermore, the interior of the shed is fixedly connected to two movable shafts, and each of the two movable shafts has a sliding groove at its opposite end. The movable crossbars are all square in design and slide between the two sliding grooves.
[0014] Furthermore, motor 2 is installed inside both ends of the moving crossbar, and gear 2 is fixedly connected to the output ends of multiple motor 2. Rack 2 is installed inside both moving shafts, and gear 2 meshes with its adjacent rack 2 respectively.
[0015] Furthermore, spring plates three are fixedly connected to both ends of the second roller, and the end of the spring plate three away from the second roller is fixedly connected to the inner wall of the moving roller.
[0016] The beneficial effects of this utility model are:
[0017] 1. This utility model provides a multi-directional movable roller 3, equipped with multiple supplementary lights. The supplementary lights are connected by screws and nuts. Gear 1 meshes with rack 1, and gear 1 moves linearly inside the slot. It is fixedly connected to the support block by a ratchet and a stop block. A support rod is fixedly connected to the tail end of the support block. The support rod is wound with a spring. The spring squeezes between the support block, the stop block, and the ratchet, causing the stop block to push the ratchet to rotate. The spring then drives the support block to push the stop block. The bottom end of the movable roller 3 has a groove. Each groove has a roller bearing 1. Each roller bearing 1 is equipped with a pull-down light-blocking cloth. The pull-down light-blocking cloth is driven by the rebound force of the spring sheet to rotate the roller bearing, thereby pulling down the pull-down light-blocking cloth to block the light from the supplementary lights for flowers in different areas of the front, middle, and back.
[0018] 2. In this utility model, a horizontally stretched light-blocking cloth is fixedly connected to both sides of the inner top of the movable roller 3. One end of the horizontally stretched light-blocking cloth is connected to the upper support rod. The horizontally stretched light-blocking cloth drives the roller bearing 2 to rotate through the rebound force of the spring plate 2. When the horizontally stretched light-blocking cloth unfolds to the left and right, the gear 2 meshes with the rack 2 and moves back and forth, thereby driving the horizontally stretched light-blocking cloth to move and unfold to the left and right sides, thereby blocking the direction of sunlight shining from the top.
[0019] 3. This invention reduces light intensity through components such as a pull-down shading cloth and a horizontal shading net. The light adjustment device can precisely adjust the light intensity according to the type of flower, preventing leaf burn caused by direct sunlight. In cases of insufficient light, supplemental lighting can be used to increase light intensity, ensuring that flowers have sufficient energy for photosynthesis in a suitable environment, thereby promoting flower growth and development. The light adjustment device also influences the greenhouse temperature. The shading cloth, while blocking sunlight and reducing light intensity, also reduces the amount of solar radiation heat absorbed by the greenhouse, thus lowering the greenhouse temperature. In summer, appropriate shading can prevent flowers from suffering high-temperature damage; in winter, rationally utilizing light increases heat absorption, creating a relatively stable growing environment for the flowers.

[0029] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will provide further details.
[0030] Please refer to Figures 1-7 This utility model proposes a light adjustment device for a flower cultivation greenhouse, including a greenhouse body 1, a horizontal shading component, and a vertical shading component. The horizontal shading component blocks the light from the supplemental lighting 24, forming a sealed space, while the vertical shading component blocks sunlight to prevent direct sunlight from entering the greenhouse.
[0031] The vertical shading component is installed inside the canopy 1. The vertical shading component includes two rack shafts 2. A rack 25 is fixedly connected to the bottom of one rack shaft 2. A movable roller 3 is slidably connected between the two rack shafts 2. A motor 4 is installed inside one side of the movable roller 3. A gear 5 is fixedly connected to the output end of the motor 4. The gear 5 meshes with the rack 25. When the motor 4 drives the gear 5 to rotate, due to the meshing of the gear 5 with the rack 25, the motor 4 moves to one side due to the resistance of the rack 25 when the gear 5 rotates. This causes the movable roller 3 to move parallel to the two rack shafts 2.
[0032] A roller 6 is rotatably connected to the lower inner side of the moving roller 3. A pull-down light-blocking cloth 7 is fixedly connected to the roller 6. The pull-down light-blocking cloth 7 is rolled around the outside of the roller 6. Spring plates 8 are fixedly connected to both sides of the roller 6. The ends of the two spring plates 8 away from the roller 6 are fixedly connected to the inner wall of the moving roller 3. When the pull-down light-blocking cloth 7 is pulled, the roller 6 rotates with the pull-down light-blocking cloth 7. When the roller 6 rotates, it drives the spring plates 8 to rotate, but the other end of the spring plates 8 remains fixed. Therefore, when the roller 6 rotates, the spring plates 8 deform and generate elastic force. When the pull-down light-blocking cloth 7 is pulled to a certain position, the pull-down light-blocking cloth 7 is released. At this time, since the pull-down light-blocking cloth 7 releases the force applied to the roller 6, the rebound force of the spring plates 8 drives the roller 6 to rotate back, and then rolls the pull-down light-blocking cloth 7 back around the outside of the roller 6, realizing its winding function.
[0033] A ratchet 9 is fixedly connected to one side of the roller 6. A pull rod 10 is slidably connected to the outside of the moving roller 3. A connecting block 11 is fixedly connected to the end of the pull rod 10 near the ratchet 9. A pawl 12 is rotatably connected inside the connecting block 11, and the pawl 12 meshes with the ratchet 9. A spring 13 is sleeved on the outside of the pull rod 10. A pull rope 14 is fixedly connected to the end of the pull rod 10 away from the connecting block 11. When the pull-down blackout cloth 7 is pulled, causing the roller 6 to rotate, the roller 6 drives the ratchet 9 to rotate smoothly. When the clock hand rotates, the pawl 12 rotates on the lever 10, thus pushing the ratchet 9 to rotate clockwise, making the pawl 12 unable to block the rotation of the ratchet 9. However, when the spring plate 8 drives the roller 6 to rotate and then drives the ratchet 9 to rotate counterclockwise, the bottom of the pawl 12 is blocked by the lever 10 and cannot rotate, thus blocking the rotation of the ratchet 9. Therefore, when the pull-down blackout cloth 7 is pulled to a certain position, it cannot automatically roll up and achieve its blackout function.
[0034] After the blackout cloth 7 is used, pull the pull rope 14 to move the pull rod 10 to the side opposite to the moving roller 3, which in turn moves the pawl 12 to disengage it from the ratchet 9. At this time, the pawl 12 releases its restriction on the ratchet 9. Therefore, under the action of the spring plate 8, the roller 6 can drive the blackout cloth 7 to automatically rewind. Since the connecting block 11 squeezes the spring 13 when it moves, after the blackout cloth 7 is rewound, the pull rope 14 is released, and the spring 13 rebounds and pushes the pawl 12 to engage with the ratchet 9 again, thereby restricting its rotation and fixing the roller 6.
[0035] A horizontal shading assembly is installed inside the shed body 1. The horizontal shading assembly includes two rollers 15, both of which are rotatably connected to the top of a movable roller 3. A horizontal shading cloth 16 is fixedly connected to the outside of each of the two rollers 15. A movable crossbar 18 is fixedly connected to the side of the horizontal shading cloth 16 away from the rollers 15. A motor 19 is installed inside both ends of the movable crossbar 18. Gears 20 are fixedly connected to the output ends of multiple motors 19. Two movable shafts 22 are fixedly connected inside the shed body 1. A rack 21 is installed inside each of the two movable shafts 22. The gears 20 mesh with their adjacent racks 21. Each of the two moving shafts 22 has a groove 23 at its opposite end. The moving crossbar 18 moves between the two grooves 23. When it is necessary to shade the top, the motor 19 is started. The motor 19 drives the gear 20 to rotate. Since the gear 20 meshes with the rack 21, it cannot rotate due to the resistance of the rack 21. The moving crossbar 18 is square and slides inside the groove 23. Therefore, when the gear 20 rotates, it pushes the moving crossbar 18 to move between the two moving shafts 22, thereby pulling the horizontal shading cloth 16 to open at the top, thus achieving the shading function at the top.
[0036] Both ends of the second spool 15 are fixedly connected to spring plates 3 17. The ends of the spring plates 3 17 away from the second spool 15 are fixedly connected to the inner wall of the moving roller 3. When the moving crossbar 18 pulls the spring plates 3 17 open, the second spool 15 rotates as the spring plates 3 17 are pulled up. When the second spool 15 rotates, the other end of the spring plates 3 17 is fixed. Therefore, when the second spool 15 rotates, the spring plates 3 17 deforms and generates elastic force. When the motor 2 19 drives the gear 2 20 to reverse, the tension of the spring plates 3 17 is released. At this time, the spring plates 3 17 rebounds and drives the second spool 15 to reverse. As 174 is continuously retracted, the spring plates 3 17 are then rewound onto the second spool 15, realizing its winding function.
[0037] Supplemental lights 24 are installed on both sides of the moving roller 3. The supplemental lights 24 are used to provide supplemental lighting for the flowers.
[0038] In summary, by installing the down-pulling shading cloth 7 and the horizontal shading cloth 16, the light in the greenhouse can be adjusted vertically and horizontally. According to the needs of flower cultivation, the supplementary light lamp 24 and sunlight can be blocked for flowers in different areas, and the light exposure can be flexibly adjusted. Shading can also be carried out on cloudy or rainy days when ventilation is needed, so as to create a suitable light environment for flower growth.
[0039] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
