Description

Technical Field

[0001] This invention relates to the field of aerospace planting technology, specifically to a planting device for aerospace planting. Background Technology

[0002] The space planting device is mainly used to realize the full-cycle cultivation of plants in the microgravity environment of space to support the life support system and the needs of astronauts in long-term manned flight missions. At the same time, the device's lighting system optimizes plant photosynthesis through the combination of red, blue and white light. Astronauts can take care of the plants at any time through the open structure and use their photosynthesis to absorb carbon dioxide and release oxygen, as well as achieve water regeneration through transpiration, thereby reducing the cost of logistical supplies.

[0003] Fresh plants can also regulate the psychological state of astronauts and relieve the stress of long-term confined environment. At present, China's space station has successfully grown crops such as lettuce and cherry tomatoes, verified the relevant technologies, and laid the foundation for the ecological life support system of future deep space exploration. Watering the planting medium is a problem that must be considered in space planting. Due to the gravitational effect in space, it is impossible to directly water the plants. The conventional method is to use capillary tubes inserted into the planting medium to achieve a stable water supply to the planting medium.

[0004] However, the current water supply method is not convenient enough. When supplying water to the planting medium, a capillary tube needs to be inserted into the planting medium. However, this method is not convenient in actual use and may break up the medium. Therefore, a planting device for aerospace planting is proposed to solve the above problems.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 2 This embodiment describes a planting device for aerospace planting, comprising a base 1. Multiple load-bearing rods 12 are fixed to the inner bottom wall of the base 1, and a connecting plate 13 is fixed to the top of each load-bearing rod 12. When it is necessary to promote the lifting and lowering of the receiving component 4, the weight of the receiving component 4 and the planting structure 6 will act on the connecting plate 13. At this time, the load-bearing rods 12 support the connecting plate 13, ensuring the stable lifting and lowering of the receiving component 4 and the planting structure 6. A control mechanism 5 is provided on the inner right wall of the base 1. A receiving component 4 extending out of the base 1 is provided inside the control mechanism 5. A drive mechanism 2 for driving the receiving component 4 to rotate is provided on the outer surface of the receiving component 4 and located inside the base 1. A support is fixed to the bottom of the drive mechanism 2. A plate 11 and multiple load-bearing rods 12 all penetrate the support plate 11. A servo controller 10 is fixed on the inner right wall of the base 1 and on the right side of the drive mechanism 2. The servo controller 10 can control the drive mechanism 2 and the control mechanism 5. The bottom of the base 1 is provided with a connecting component 3 that penetrates the inner bottom wall of the base 1 and ensures that water flows smoothly into the receiving component 4. The connecting component 3 extends into the receiving component 4 and is fixed to the receiving component 4. The top of the receiving component 4 is provided with multiple planting structures 6 that can hold planting culture medium. Four support rods 7 are fixed on the top of the base 1. A top plate 8 is fixed on the top of the four support rods 7. A light lamp 9 is fixed on the bottom of the top plate 8. The light lamp 9 is used to provide light for the plants and ensure that the plants can carry out photosynthesis smoothly.

[0032] In addition, the drive mechanism 2 includes a primary servo motor 201 fixed to the top of the support plate 11. A primary worm gear 202 is fixed to one end of the output shaft of the primary servo motor 201. A primary worm wheel 203 is meshed on the front side of the primary worm gear 202. The primary servo motor 201 can provide stable power for the rotation of the primary worm gear 202, and drive the primary worm wheel 203 to rotate smoothly through the primary worm gear 202.

[0033] In addition, the connecting component 3 includes a water inlet pipe 301 fixed to the bottom of the base 1 and penetrating the bottom wall of the base 1. External water enters the device through the water inlet pipe 301. The bottom of the water inlet pipe 301 is flush with the bottom of the base 1. A movable pipe 302 is fixedly connected to the bottom of the receiving plate 402 and located inside the connecting cylinder 401. During normal water supply, water enters the receiving plate 402 through the movable pipe 302 from the water inlet pipe 301. The water inlet pipe 301 extends into the movable pipe 302. A primary sealing bearing is fixed on the outer surface of the water inlet pipe 301 and located inside the movable pipe 302. The primary sealing bearing is used to improve the sealing between the water inlet pipe 301 and the movable pipe 302. A sealing ring 303 is fixed on the outer side of the primary sealing bearing. The side of the moving tube 302 is in contact with the inner wall of the moving tube 302, and the sealing ring 303 can also prevent water from overflowing. Multiple limiting grooves are opened on the inner side of the moving tube 302. Multiple limiting blocks 304 extending into the multiple limiting grooves are fixed on the outer side of the sealing ring 303. The side wall of the limiting block 304 is in contact with the inner wall of the limiting groove. The limiting block 304 can ensure that the moving tube 302 rises stably while effectively blocking water. The receiving component 4 includes a connecting cylinder 401 fixed to the inner side of the first-stage worm gear 203. When the first-stage worm gear 203 rotates, it will drive the connecting cylinder 401 to rotate. A receiving plate 402 is fixed on the top of the connecting cylinder 401. Multiple water passages are opened on the receiving plate 402. Water enters the planting structure 6 through the water passages from the moving tube 302.

[0034] It should be further explained that the connecting cylinder 401 and the support plate 11 are rotatably connected by a bearing. Since the connecting cylinder 401 will rotate, but the support plate 11 cannot rotate, the bearing provides support force to the support plate 11 while ensuring that the support plate 11 is not affected by the rotation of the connecting cylinder 401. The outer surface of the connecting cylinder 401 is threadedly connected to the secondary worm gear 503. The top of the connecting plate 13 is fixed with a primary plane bearing, and the connecting plate 13 is rotatably connected to the secondary worm gear 503 through the primary plane bearing.

[0035] It is known that the control mechanism 5 includes a secondary servo motor 501 fixed to the inner right wall of the base 1. The secondary servo motor 501 can provide a stable driving force for the secondary worm gear 502. The secondary worm gear 502 is fixed to one end of the output shaft of the secondary servo motor 501. The left side of the secondary worm gear 502 is rotatably connected to the inner left wall of the base 1 through a bearing. The front side of the secondary worm gear 502 is engaged with a secondary worm wheel 503. When the primary servo motor 201 and the secondary servo motor 501 start at the same time and rotate in the same direction, for example, when they rotate clockwise at the same time, since the primary servo motor 201 and the secondary servo motor 501 are placed opposite each other, the primary worm gear 202 and the secondary worm gear 502 will rotate in opposite directions at the same time. At this time, the connecting cylinder 401 and the secondary worm wheel 503 will rotate in opposite directions, realizing the rotation and lifting of the receiving component 4.

[0036] In this embodiment, the servo controller 10 simultaneously controls the primary servo motor 201 and the secondary servo motor 501 to achieve the purpose of simultaneously driving the primary worm gear 202 and the secondary worm gear 502 to rotate. When the primary worm gear 202 and the secondary worm gear 502 rotate in the same direction, they will cause the receiving component 4 to rotate. When the primary worm gear 202 and the secondary worm gear 502 rotate in opposite directions, they will cause the receiving component 4 to rotate and rise.

[0037] Please refer to it again. Figure 1 and Figures 3 to 6 To ensure a stable water supply, each planting structure 6 in this embodiment includes a shell 601 fixedly connected to the top of the receiving component 4. A pressurizing cavity 606 is formed in the bottom wall of the shell 601, providing sufficient space for a pressurizing mechanism 608. The pressurizing mechanism 608 pressurizes the water, thereby ensuring a more stable injection of water into the planting medium. Multiple clearance cavities 607, connected to the pressurizing cavity 606, are formed in the side wall of the shell 601. These clearance cavities provide sufficient space for the water supply component 602, and each clearance cavity 607 contains a water supply component 602. A rotating groove, connected to the multiple clearance cavities 607, is formed on the outer side of the shell 601. The tank is equipped with a water injection component 603 that penetrates the clearance cavity 607 and extends into the inner cavity of the outer shell 601. Water is guided to the water injection component 603 through the water supply component 602, and then water is injected into the planting medium through the water injection component 603 to achieve a stable water supply to the planting medium. Multiple water supply components 602 are fixedly connected to the water injection component 603. The top of the outer shell 601 is threadedly connected to the top cover 604. When the top cover 604 is rotated, the rotation force will be linked to the water injection component 603, causing the water injection component 603 to be inserted into the planting medium. An extension cylinder 605 is fixed to the outside of the top cover 604, extending to the outside of the water injection component 603 and engaging with the water injection component 603. The extension cylinder 605 is used to transmit the force of rotating the top cover 604 to the water injection component 603.

[0038] Furthermore, the bottom of the outer shell 601 is fixedly connected to the top of the receiving plate 402. The bottom of the outer shell 601 has multiple inclined channels connected to the pressurizing chamber 606. The inclined channels can accelerate the speed of water flow to the outside of the pressurizing mechanism 608 and reduce the burden on the pressurizing mechanism 608. Each water supply component 602 includes a stabilizing block 6021 fixed to the inner wall of the relief chamber 607. A tapered tube 6022 is fixed to the inner side of the stabilizing block 6021, penetrating the stabilizing block 6021 and flush with the bottom of the stabilizing block 6021. A corrugated hose 6023 is fixedly connected to the top of the tapered tube 6022 and above the stabilizing block 6021. When the water injection component 603 is inserted into the planting medium, the corrugated hose 6023 is needed to ensure stable water flow. The corrugated hose 6023 has good extensibility and can better adapt to the water injection component 603.

[0039] In addition, the water injection assembly 603 includes a rotating ring 6031, with secondary planar bearings fixed at both the top and bottom. These bearings provide good support for the rotating ring 6031 while ensuring its stable rotation. The rotating ring 6031 is rotatably connected to a rotating groove via the secondary planar bearings. Multiple water injection heads 6032 extending into the inner cavity of the outer shell 601 are movably connected to the inner side of the rotating ring 6031. The side of each water injection head 6032 away from the rotating ring 6031 is tapered, a shape that allows for easier insertion into the planting medium. Each injection head... Each water head 6032 has a baffle 6033 fixed on its outer surface and inside the pressurization chamber 606. Each baffle 6033 has a compression spring 6034 on the side away from the rotating ring 6031. The baffle 6033 and the compression spring 6034 work together to ensure that when the top cover 604 is removed, the water head 6032 can retract smoothly into the relief chamber 607, which is convenient for the subsequent placement of planting culture medium. The other end of the compression spring 6034 abuts against the side wall of the relief chamber 607. The bottom of the multiple water heads 6032 is fixedly connected to multiple corrugated hoses 6023.

[0040] In addition, the pressurizing mechanism 608 includes a micro motor 6081 fixed to the bottom wall of the outer casing 601. The output end of the micro motor 6081 is fixed with a rotating rod 6082 extending into the pressurizing chamber 606. A secondary sealed bearing is fixed to the outer surface of the rotating rod 6082. The rotating rod 6082 is rotatably connected to the top wall of the pressurizing chamber 606 through the secondary sealed bearing. The secondary sealed bearing also has good sealing performance, which can provide good protection for the micro motor 6081. Multiple blades 6083 are fixed to the outer surface of the rotating rod 6082. When the blades 6083 rotate around the rotating rod 6082, they can drive the water to flow together.

[0041] It should be further explained that the inner side of the rotating ring 6031 is provided with multiple arc-shaped grooves. Each water injection head 6032 has a moving rod fixed at its top and bottom. The multiple moving rods extend to the multiple arc-shaped grooves and are movably connected to the arc-shaped grooves. When the rotating ring 6031 is rotated, due to the cooperation between the arc-shaped grooves and the moving rods, as well as the limiting effect of the stabilizing rod and the connecting rod, the water injection head 6032 can be moved horizontally. The top of each water injection head 6032 is fixed with a stabilizing rod. The inner wall of each relief cavity 607 is fixed with a connecting rod that passes through the stabilizing rod. The outer side of the rotating ring 6031 is fixed with multiple external teeth. Through the meshing of the external teeth and internal teeth, the rotational force of the extension cylinder 605 can be smoothly transmitted to the rotating ring 6031. The inner side of the extension cylinder 605 is fixed with multiple internal teeth. The multiple external teeth mesh with the multiple internal teeth respectively.

[0042] In this embodiment, the pressurization mechanism 608, the water supply component 602, and the water injection component 603 work together to ensure that water is smoothly and stably injected into the planting medium, thereby achieving a stable water supply to the plants. The operation is simple and convenient.

[0043] Understandably, through the cooperation of the drive mechanism 2 and the control mechanism 5, it is possible to achieve multi-angle lighting of the plants by the light lamp 9, and it is also convenient for subsequent maintenance. At the same time, it is only necessary to place the planting medium into the planting structure 6 to complete the stable and continuous water supply to the planting medium.

[0044] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0045] The working principle of the above embodiments is as follows:

[0046] (1) When planting plants, first place the seeds or seedlings into the planting medium, then place the planting medium into the outer shell 601, then screw on the top cover 604 and rotate the top cover 604. At this time, the power of rotating the top cover 604 is transmitted to the rotating ring 6031 through the extension tube 605, thereby causing multiple water injection heads 6032 to move into the outer shell 601 at the same time. When the top cover 604 is fully screwed in, the water injection head 6032 is also successfully inserted into the planting medium.

[0047] (2) When water is supplied, start the micro motor 6081 to drive the blade 6083 to rotate. When the water flows to the blade 6083 in the pressurization chamber 606, the water will follow the blade 6083 to rotate due to the action of the blade 6083. Due to the centrifugal force, the water will be thrown to the outside, thereby achieving the pressurization effect. The pressurized water enters the water injection head 6032 through the conical tube 6022 and the corrugated hose 6023, thereby achieving a stable water supply to the planting culture medium.

[0048] (3) During planting, the plants are illuminated by the light lamp 9, and the first-level servo motor 201 and the second-level servo motor 501 are started simultaneously. At this time, the first-level servo motor 201 and the second-level servo motor 501 rotate in opposite directions. Since the first-level servo motor 201 and the second-level servo motor 501 are placed opposite each other, the first-level worm gear 202 and the second-level worm gear 502 will rotate synchronously in the same direction, ensuring that the first-level worm wheel 203 and the second-level worm wheel 503 rotate synchronously, further driving the connecting cylinder 401 and the receiving plate 402 on it to rotate, thereby achieving sufficient light for the plants.

[0049] (4) When maintenance or inspection is required, the first-level servo motor 201 and the second-level servo motor 501 are started synchronously, and the first-level servo motor 201 and the second-level servo motor 501 are rotated in the same direction. At this time, the first-level worm 202 and the second-level worm 502 will rotate synchronously in opposite directions. Due to the threaded connection between the connecting cylinder 401 and the second-level worm wheel 503, and their opposite rotation, the connecting cylinder 401 will drive the receiving plate 402 to rotate and rise, which makes it easier for the staff to maintain and inspect the structure inside the base 1.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
