Description

Technical Field

[0001] This application relates to the field of plant cultivation equipment technology, and in particular to a carbon sink device that enhances plant photosynthesis. Background Technology

[0002] Photosynthesis is generally referred to as the process by which green plants absorb light energy, synthesize energy-rich organic matter from carbon dioxide and water, and release oxygen at the same time. It mainly includes two stages: light reaction and dark reaction, involving important reaction steps such as light absorption, electron transfer, photophosphorylation, and carbon assimilation. It is of great significance for realizing energy conversion in nature and maintaining the carbon-oxygen balance of the atmosphere.

[0003] CN221689388U discloses "a device for enhancing carbon sequestration in plant photosynthesis, including a water tank, a water pump on the water tank, and a reinforcing rib between the support plate and the main body". This utility model, by setting threaded connections between extended pipes, allows the height of the device to be adjusted according to the height of the part of the plant to be irradiated, making it highly applicable. By setting an adjustment device, a motor drives the drive gear to rotate, and the drive gear meshes with the driven gear to drive the L-shaped delivery pipe to rotate, which can switch the water spray plate and the illumination lamp. After watering, the plant is illuminated. Watering and illumination are integrated into one device, which is convenient to use.

[0004] However, in practical applications, this device has revealed significant limitations. The fixed angle and position of the illumination lamps make it difficult to meet the diverse planting needs of the plant canopy in terms of light uniformity. Taking common crops as an example, in the vigorous growth stage, the lower and middle leaves of the plant cannot obtain sufficient light, resulting in a significantly lower photosynthetic efficiency compared to the top leaves. This, in turn, affects the overall carbon absorption efficiency and growth status of the plant, limits the full utilization of plant photosynthesis, and weakens the carbon sequestration effect. Therefore, a carbon sequestration device to enhance plant photosynthesis is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] This application discloses a carbon sink device to enhance plant photosynthesis. (Refer to...) Figure 1-3 A carbon sink device for enhancing plant photosynthesis includes an inner toothed ring 1 and multiple connecting seats 2. The number of connecting seats 2 is set according to the device's application scenario and load-bearing requirements, typically 4-8, and they are evenly distributed in a circumferential array with equal spacing. The connecting seats 2 are made of high-strength aluminum alloy and formed by precision casting. Their inner walls are machined with high-precision annular slide rails, and the slide rail surfaces are anodized to improve wear resistance and corrosion resistance. The inner toothed ring 1 is also made of aluminum alloy, and its inner teeth and outer wall annular grooves are milled by a CNC machining center. The annular grooves on the outer wall of the inner toothed ring 1 cooperate with the annular slide rails on the inner wall of the connecting seats 2 to form a rotating pair, enabling the inner toothed ring 1 to achieve stable and flexible rotation within the connecting seats 2. The radial runout error during the rotation process is controlled within ±0.05mm.

[0024] The top outer wall of the inner toothed ring 1 is symmetrically fixed with two fixing plates 7 by welding. The welding adopts argon arc welding technology to ensure welding strength and surface flatness. The fixing plates 7 are made of 5mm thick stainless steel plates, which have good strength and weather resistance. The top outer wall of the fixing plates 7 is fixed with the upright plate 8 by bolt connection. The outer wall of the upright plate 8 is equipped with illumination lamps 9 through an angle adjustment mechanism. The two illumination lamps 9 adopt an arc design, which can better fit the shape of the plant canopy and improve the uniformity of light. The illumination lamps 9 are high-brightness LED lamp groups.

[0025] The angle adjustment mechanism consists of a base 19, a worm gear 16, a rotating shaft 13, and a worm wheel 15. The base 19 is fixed to the outer wall of the upright plate 8 by welding. The welding position is precisely calculated to ensure the installation accuracy of the base 19. The worm gear 16 is rotatably connected to the inner wall of the base 19 by two high-precision deep groove ball bearings. The bearings are installed in the bearing holes pre-machined in the base 19, and the dimensional accuracy of the bearing holes is controlled at H7 level. The two ends of the rotating shaft 13 are respectively fitted with connecting parts 12, which are made of stainless steel and are fastened to the rotating shaft 13 by bolts. The worm wheel 15 is fixed to the outer wall of the rotating shaft 13 by interference fit. The tooth profile of the worm wheel 15 and the worm gear 16 is optimized by professional gear design software. The module, pressure angle and other parameters of the two are matched to ensure the accuracy and stability of the meshing transmission. The transmission efficiency can reach more than 90%. The two ends of the rotating shaft 13 are fixedly connected to the movable ears 14 by the connecting parts 12. The movable ears 14 are bolted to the outer wall of the illumination lamp 9 for easy disassembly and maintenance.

[0026] The outer wall of the base 19 is fixedly connected to two bushings 11 by welding. A symmetrical welding method is used during welding to reduce welding deformation. The bushings 11 are made of copper alloy, which has good wear resistance and self-lubricating properties. Their inner walls are finely ground to achieve a surface roughness of Ra0.8. Two connecting parts 12 are rotatably connected to the inner walls of the two bushings 11 respectively. A rotational fit is formed between the connecting parts 12 and the bushings 11. The rotation process is smooth and there is no jamming. The bushings 11 provide stable support for the connecting parts 12, ensuring the coaxiality of the rotating shaft 13 during rotation and improving the motion accuracy of the angle adjustment mechanism.

[0027] The stepper motor 17 is fixedly mounted on the outer wall of the base 19 facing downwards using four high-strength bolts. The bolts are tightened diagonally to ensure flatness and stability. The output shaft of the stepper motor 17 is fixedly connected to one end of the worm gear 16 via a flat key. The size of the flat key precisely matches the keyway of the motor output shaft and the worm gear 16 to ensure reliable power transmission. The stepper motor 17 is a microstepping drive type, characterized by high-precision positioning and smooth low-speed operation. Its step angle is 1.8°. Through microstepping drive technology, smaller angle control can be achieved to meet the needs of precise angle adjustment of the illumination lamp 9. When the stepper motor 17 receives a control signal, it precisely rotates the corresponding angle according to the preset pulse sequence, driving the worm gear 16 to rotate on the inner wall of the base 19, which in turn drives the worm wheel 15 and the rotating shaft 13 to rotate, thereby achieving precise angle adjustment of the illumination lamp 9.

[0028] The outer wall of the base 19 is fixedly connected to the fixing tile 10 by multiple high-strength bolts. The number and distribution of the bolts are reasonably designed according to the size and stress of the fixing tile 10. The fixing tile 10 is made of aluminum alloy and is formed by die casting. It and the base 19 cooperate to form a closed space, completely enclosing the rotating shaft 13, worm gear 15, worm 16 and bushing 11. A rubber sealing ring is set between the fixing tile 10 and the base 19. The sealing ring is made of high temperature resistant and aging resistant silicone rubber. During installation, sealant is applied to the surface of the sealing ring to ensure the sealing effect. This closed structure can effectively prevent dust, moisture and oil from entering the internal transmission components, reduce the wear of the components, extend the service life of the device, and also reduce maintenance costs and frequency.

[0029] The bottom outer walls of multiple connecting seats 2 are fixedly connected to support legs 3 by welding. Support legs 3 are made of tapered steel pipes. The inner walls of multiple support legs 3 are welded with connecting rings 4 by welding. Connecting rings 4 are made of round steel and the welded joints are ground to ensure a smooth surface. Connecting rings 4 and multiple support legs 3 form a stable support structure, which supports and limits the internal toothed ring 1, ensuring the stability of the internal toothed ring 1 during rotation.

[0030] The outer wall of the connecting ring 4 is fixedly mounted with the drive motor 5 by a welded mounting bracket. The mounting bracket is made of angle steel and has sufficient strength and rigidity. The drive motor 5 is a servo motor, and its output shaft end is fixedly connected to the gear 6 by a coupling. The coupling has a certain ability to compensate for the relative misalignment of the two shafts, ensuring the smoothness of power transmission. The gear 6 is machined with high precision, and the tooth profile adopts an involute tooth profile. Its module, pressure angle and other parameters are matched with the internal teeth of the internal gear ring 1. The meshing backlash between the gear 6 and the internal gear ring 1 is controlled between 0.1-0.2mm to ensure the accuracy and reliability of transmission. When the drive motor 5 receives a control signal, it drives the gear 6 to rotate. Since the gear 6 meshes with the internal gear ring 1, the rotation driving force of the gear 6 is transmitted to the internal gear ring 1, driving the internal gear ring 1 to rotate slowly along the annular slide rail in the connecting seat 2, realizing the horizontal position adjustment of the illumination lamp 9. The drive motor 5 has a high-precision position feedback system, which can monitor the rotation angle and position of the internal gear ring 1 in real time to ensure that the illumination lamp 9 can move accurately to the preset position.

[0031] Angle ruler 18 is bolted to one side of the outer wall of base 19. The angle ruler 18 is made of stainless steel with angle markings laser-etched on its surface, resulting in clear and wear-resistant markings. The scale range of angle ruler 18 is 0-180° with an accuracy of 1°. An indicator is fixed to the outer wall of one of the movable ears 14 with screws. The indicator is a pointer-like structure made of plastic with a reflective coating for easy observation. When the angle of the illumination lamp 9 changes, the movable ear 14 drives the indicator to rotate synchronously, aligning with the markings on angle ruler 18. Operators can visually obtain the rotation angle of the illumination lamp 9. In actual use, operators can set the target angle of the illumination lamp 9 through the control system according to the plant's growth status and light requirements. The stepper motor 17 rotates precisely according to the set angle, while simultaneously observing the indicator and the markings on angle ruler 18 to ensure the illumination lamp 9 is accurately adjusted to the required angle, providing optimal light conditions for the plant, effectively enhancing photosynthetic efficiency and carbon sequestration capacity.

[0032] The implementation principle of a carbon sink device for enhancing plant photosynthesis in this application embodiment is as follows: First, during the device installation stage, the support legs 3 at the bottom of multiple connecting seats 2 are fixed to the ground. The connecting rings 4 welded to the inner sidewalls of the multiple support legs 3 together with the support legs 3 form a stable support structure, which supports the inner toothed ring 1. Then, the inner toothed ring 1 is rotatably connected to the inner wall of the multiple connecting seats 2 to ensure that the inner toothed ring 1 can rotate flexibly within the connecting seats 2.

[0033] Then, the plant is placed in the middle of the inner toothed ring 1 for irradiation. When the position of the irradiation lamp 9 needs to be adjusted, the drive motor 5 on the outer wall mounting bracket of the connecting ring 4 is started. The gear 6 at the end of the output shaft of the drive motor 5 meshes with the inner toothed ring 1. The drive motor 5 drives the gear 6 to rotate, thereby driving the inner toothed ring 1 to rotate in the connecting seat 2, so as to realize the horizontal position adjustment of the irradiation lamp 9. When the two irradiation lamps 9 rotate around the plant, they can irradiate the plant from all directions without blind spots.

[0034] To adjust the angle of the illumination lamp 9, the stepper motor 17, which is fixedly installed on the outer wall of the base 19 facing downwards, is activated. The output shaft of the stepper motor 17 passes through the base 19 and is fixedly connected to one end of the worm gear 16. The operation of the stepper motor 17 drives the worm gear 16 to rotate on the inner wall of the base 19. Since the worm wheel 15 is fixedly connected to the outer wall of the rotating shaft 13 and meshes with the worm gear 16, the rotation of the worm gear 16 drives the worm wheel 15 to rotate, thereby driving the rotating shaft 13 to rotate. The two ends of the rotating shaft 13 are fixedly connected to the movable ears 14 through the connectors 12. The movable ears 14 are connected to the outer wall of the illumination lamp 9. Therefore, the rotation of the rotating shaft 13 can realize the adjustment of the angle of the illumination lamp 9. The two bushings 11 fixedly connected to the outer wall of the base 19 provide rotational support for the connectors 12, ensuring the stability of the rotating shaft 13 during rotation. At the same time, the fixing plate 10 fixedly connected to the outer wall of the base 19 by bolts encloses the rotating shaft 13, worm wheel 15, worm gear 16 and bushings 11 in the space formed between them and the base 19, which plays a role in protecting the internal transmission components.

[0035] During the adjustment of the angle of the illumination lamp 9, the angle ruler 18 set on the outer wall of one side of the base 19 is used in conjunction with the index on the outer wall of the movable ear 14. The operator can intuitively obtain the rotation angle of the illumination lamp 9, which is convenient for precise adjustment to meet the light needs of different parts of the plant, enhance the photosynthetic efficiency of the plant, and improve the carbon sequestration capacity.
