Description

Technical Field

[0001] This utility model relates to the field of facility agriculture technology, and in particular to a rapid height adjustment and lifting component for greenhouse plant supplemental lighting. Background Technology

[0002] The height-adjustable lifting component for greenhouse plant supplemental lighting uses wear-resistant materials and a control design. It allows for quick adjustment of the lighting height via manual knobs and electric buttons, matching the light distance requirements of different plant growth stages. This convenient adjustment ensures that the supplemental lighting is more tailored to the plant's needs, avoiding excessive or insufficient light due to a fixed height. It improves light energy utilization, helps plants grow steadily, and provides strong support for improving the quality and efficiency of greenhouse cultivation.

[0003] Traditional height-adjustable lifting components for greenhouse plant grow lights mostly rely on manual operation. The height is fixed by rope traction and bracket clips. When adjusting, the connecting parts need to be loosened manually and the position of the lamp body needs to be moved. After that, it needs to be locked again to maintain the height. This has the problems of slow adjustment speed and insufficient precision. The operation process is time-consuming and laborious, and it is difficult to meet the frequent height adjustment needs of plants during the rapid growth stage.

[0004] Existing height-adjustable lifting components for greenhouse plant grow lights mostly use motor-driven lead screws and slide rail structures. By inputting commands through the control panel, the lamp body is moved up and down to achieve rapid height adjustment. However, the problem of thermal expansion and contraction due to the difference in expansion coefficients caused by the temperature difference between day and night still exists. To address this issue, a height-adjustable lifting component for greenhouse plant grow lights is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a height-adjustable lifting and lowering component for greenhouse plant supplemental lighting, which aims to improve the problem in the prior art where the difference in the coefficients of thermal expansion and contraction between day and night temperatures causes thermal expansion and contraction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a height-adjustable lifting assembly for greenhouse plant supplemental lighting, comprising a roller column, a buffer mechanism provided on the outside of the roller column, two pulleys fixedly connected to the outer wall of the roller column, positioning plates fixedly connected to the outer walls of the two pulleys, two retractable blocks fixedly connected to the outer wall of the roller column, pull ropes fixedly connected to the outer walls of the two retractable blocks, insect-proof mechanisms provided at the bottom ends of the two pull ropes, and a housing fixedly connected to the left side of the roller column, with a drive mechanism provided inside the housing;

[0007] The buffer mechanism includes multiple pads, the outer walls of which are fixedly connected to the outer walls of the rollers.

[0008] As a further description of the above technical solution:

[0009] The insect-proof mechanism includes two connecting plates. The inner walls of the two connecting plates are fixedly connected to the bottom of the pull rope. The bottom of the two connecting plates is fixedly connected to a fixing plate. The front and rear sides of the fixing plate are fixedly connected to water baffles. The top of the two water baffles is provided with a drainage groove. The bottom of the fixing plate is fixedly connected to an insect-proof net. The bottom of the fixing plate is fixedly connected to a light plate. The outside of the insect-proof net is provided with a fixing component.

The water-blocking plate and drainage channel work together to prevent water accumulation and the breeding of mosquitoes and other pests, cutting off the breeding environment of pests from the source and improving the stability of the light.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0035] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a rapid height adjustment and lifting assembly for greenhouse plant supplemental lighting, including a roller 5. Its main function is to rotate and drive the retractable blocks 8 to move synchronously, thereby achieving the winding and releasing of the pull rope 14. A buffer mechanism 4 is provided on the outside of the roller 5. Two pulleys 3 are fixedly connected to the outer wall of the roller 5, mainly for sliding the roller 5. Positioning plates 2 are fixedly connected to the outer walls of both pulleys 3, mainly for fixed positioning. Two retractable blocks 8 are fixedly connected to the outer wall of the roller 5, mainly for winding and releasing the pull rope 14. Pulling plates 2 are fixedly connected to the outer walls of both retractable blocks 8. The bottom ends of the two ropes 14 are equipped with insect-proof mechanisms 6. The left side of the roller 5 is fixedly connected to the housing 10. The housing 10 is equipped with a drive mechanism 9, which includes a stepper motor 901. Its main function is to provide stable rotational power. The core advantage of the stepper motor 901 is that it can precisely adjust the rotation angle and speed by controlling the pulse signal. The bottom of the stepper motor 901 is fixedly connected to the inner wall of the housing 10. The output end of the stepper motor 901 is fixedly connected to the main gear 902. The outer wall of the main gear 902 is meshed with the auxiliary gear 903. The two gears control its stable operation.

[0036] The buffer mechanism 4 includes multiple protective pads 401, whose main function is to allow the protective pads 401 to directly contact the force. The outer walls of the multiple protective pads 401 are all fixedly connected to the outer wall of the roller column 5. The outer walls of the multiple protective pads 401 are all fixedly connected to inner plates 402, whose main function is to provide structural support and force transmission. The outer walls of the multiple inner plates 402 are all fixedly connected to fixing rods 404, whose main function is to be the core rods for force transmission. The outer walls of the multiple fixing rods 404 are all fixedly connected to fixing knobs 403. Through the transition displacement of the inner column 406 within the outer column 407, the outer walls of the multiple fixing rods 404 are all fixedly connected to the inner column 406. The outer walls of the multiple fixing knobs 403 are all fixedly connected to the outer column 407. The outer walls of the outer columns 407 are provided with multiple water channels 409. Its main function is to prevent external water accumulation. The outer column 407 is provided with a connecting component 408. The connecting component 408 includes multiple buckles 4081. The outer walls of the multiple buckles 4081 are fixedly connected to the outer wall of the outer column 407. The outer walls of the two positioning plates 2 are provided with multiple slots 4082. The buckles 4081 are inserted into the slots 4082 of the positioning plates 2 to ensure that the buffer mechanism 4 is installed firmly. The outer walls of the multiple inner plates 402 are provided with elastic components 405. The buffer springs 4051 are sleeved on the outer wall of the fixing rod 404. The two ends are respectively connected to the fixing block 4052 and the relevant structure of the outer column 407. When the inner plate 402 is subjected to force and drives the fixing rod 404 to move, the spring is compressed or stretched, and most of the impact energy is absorbed through elastic deformation.

[0037] Specifically, the drive mechanism 9 includes a stepper motor 901, which provides stable rotational power. The stepper motor 901 precisely adjusts the rotation angle and speed by controlling pulse signals, thereby achieving precise control of the subsequent transmission components. It is controlled to run stably by the main gear 902 and the auxiliary gear 903.

[0038] The buffer mechanism 4 includes multiple pads 401, allowing the pads 401 to directly contact the force and absorb impact energy through their own deformation, reducing damage from rigid collisions. The inner plate 402 on the outer wall of the multiple pads 401 provides structural support and force transmission. The fixing rod 404 is the core member for force transmission. Through the transition displacement of the inner column 406 within the outer column 407, it ensures the relative movement stability of the inner column 406 and the outer column 407, providing guidance for the buffering process. Multiple drainage channels 409 on the outer wall of the outer column 407 prevent external water accumulation. The connecting assembly 408 includes multiple clips 4081 on the outer walls of the two positioning plates 2. The groove 4082 is snapped into the groove 4082 of the positioning plate 2 by the buckle 4081, ensuring that the buffer mechanism 4 is firmly installed as a whole. During the buffering process, a certain displacement space is generated, and it is easy to disassemble and maintain. The elastic component 405 includes multiple fixing blocks 4052. The buffer spring 4051 is sleeved on the outer wall of the fixing rod 404. The two ends are respectively connected to the fixing blocks 4052 and the related structures of the outer column 407. When the inner plate 402 is subjected to force and drives the fixing rod 404 to move, the spring is compressed or stretched. Most of the impact energy is absorbed through elastic deformation. The fixing blocks 4052 are used to stabilize the installation position of the spring, ensure that the spring is subjected to uniform force, and avoid displacement failure.

[0039] Reference Figure 1 , Figure 2 and Figure 6The insect-proof mechanism 6 includes two connecting plates 606, whose main function is to ensure that the entire insect-proof mechanism 6 can rise and fall synchronously with the pull rope 14. The inner walls of the two connecting plates 606 are fixedly connected to the bottom of the pull rope 14. The bottom of the two connecting plates 606 is fixedly connected to a fixing plate 602, which serves to support and position the components and provide an installation reference. Water baffles 603 are fixedly connected to the front and rear sides of the fixing plate 602, mainly to prevent condensation and irrigation splashes in the greenhouse from dripping directly onto the insect-proof net 601 and the light panel 607. The top of the two water baffles 603 is provided with a drainage groove 604, which mainly serves to quickly drain the water intercepted by the water baffles 603. The bottom of the board 602 is fixedly connected to an insect-proof net 601, whose main function is to form a physical barrier through the fine mesh structure to effectively block flying and crawling insects. The bottom of the fixed board 602 is fixedly connected to a light board 607, whose main function is to provide specific wavelengths of light required for plant growth. The outside of the insect-proof net 601 is provided with a fixing component 605, which includes multiple tenons 6052. The outer walls of the multiple tenons 6052 are fixedly connected to the outer wall of the insect-proof net 601. The bottom of the fixed board 602 is provided with multiple mortises 6051, which are mainly used to firmly fix the insect-proof net 601 to the bottom of the fixed board 602 through the cooperation of the tenons 6052 and the mortises 6051.

[0040] Specifically, the insect-proof mechanism 6 includes two connecting plates 606, ensuring that the entire insect-proof mechanism 6 can rise and fall synchronously with the pull rope 14. The fixing plate 602 at the bottom of the two connecting plates 606 serves as a load-bearing and positioning tool, while also providing an installation benchmark for the components. At the same time, the water baffle 603 prevents condensation and irrigation splashes from the greenhouse from dripping directly onto the insect-proof net 601 and the light panel 607. The drainage channel 604 quickly drains the water intercepted by the water baffle 603, preventing water retention from damaging the insect-proof net. The insect-proof net 601 becomes damp and moldy, and the light panel 607 short-circuits. The fine mesh structure of the insect-proof net 601 forms a physical barrier, effectively blocking flying and crawling insects. The main function of the light panel 607 is to provide specific wavelengths of light required for plant growth. The fixing component 605 includes multiple tenons 6052. Through the cooperation of the tenons 6052 and the mortises 6051, the insect-proof net 601 is firmly fixed to the bottom of the fixing plate 602, ensuring the stable installation of the insect-proof net 601, facilitating disassembly and replacement, and improving the practicality of the equipment.

[0041] Reference Figure 1 , Figure 2 and Figure 7The top of each of the two positioning plates 2 is fixedly connected to a top plate 1. The top plate 1 can fix the entire equipment on the top frame of the greenhouse and provide an installation foundation for the overall structure. The outer wall of the chassis 10 is fixedly connected to a cover plate 13, the main function of which is to prevent the drive components from getting damp, rusted and contaminated. The outer wall of the roller 5 is fixedly connected to a fixing button 7, the main function of which is to prevent the roller 5 from falling off. The bottom of the chassis 10 is fixedly connected to a bottom column 11, which can reduce the direct contact between the chassis 10 and the ground. The right side of the bottom column 11 is fixedly connected to a switch box 12, which controls the start, stop and forward and reverse rotation of the stepper motor 901.

[0042] Specifically, the top plate 1 can fix the entire equipment to the top frame of the greenhouse, providing an installation foundation for the overall structure. At the same time, the cover plate 13 on the outer wall of the chassis 10 prevents the drive components from getting damp, rusted, and contaminated, ensuring the long-term stable operation of the motor and gears. The fixing knob 7 on the outer wall of the roller 5 prevents the roller 5 from falling off. The bottom column 11 can reduce the direct contact between the chassis 10 and the ground, reducing the impact of ground moisture and debris on the chassis 10. The start, stop, forward and reverse rotation of the stepper motor 901 is controlled by the switch box 12 to realize the raising, lowering and stopping of the supplementary light, making operation convenient.

[0043] Working principle: First, the buffer mechanism 4 uses the pad 401 as the direct contact layer, which can immediately absorb and initially disperse external forces, reducing the intensity of local impacts. At the same time, the elastic component 405 is the core force of the buffer, which actively absorbs most of the impact force through its own deformation, transforming hard collisions into flexible buffers. The cooperation of the inner column 406 and the outer column 407 provides a stable force transmission channel for the buffering process, ensuring that the impact force is evenly distributed to each component and avoiding local overload. Meanwhile, the inner plate 402 protects the internal structure, and the water channel 409 of the outer column 407 prevents water from being stored externally, enhancing the smoothness of the buffer. The connecting component 408 makes the linkage between the various parts more tight, making the buffering action coherent and coordinated, ultimately achieving a layer-by-layer progressive buffering from contact to dissipation, improving the overall shock absorption effect.

[0044] Furthermore, through multiple designs, an efficient insect-proof barrier is constructed. The core insect-proof net 601 directly blocks the invasion of various pests, forming the first line of defense. The fixing component 605 can firmly fix the insect-proof net 601, preventing gaps due to loosening and ensuring that the barrier has no dead corners. With the cooperation of the water-blocking plate 603 and the drainage channel 604, water accumulation is prevented from breeding mosquitoes and other pests, cutting off the breeding environment of pests from the source, comprehensively improving the reliability of insect prevention, and effectively protecting the area from pest infestation.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
