Description

Technical Field

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

[0002] Space-grade solar greenhouses are innovative facilities that combine aerospace technology with agricultural planting. During space missions, these greenhouses can provide astronauts with fresh food and supplement oxygen by precisely controlling temperature, light, humidity, and gas composition. They can also achieve partial water recycling, reducing dependence on Earth resupply. Their closed-loop environmental control system can effectively cope with challenges such as microgravity and radiation in space, ensuring that plants can grow normally under weightless conditions.

[0003] Existing solar greenhouses for space cultivation mostly employ multi-layer LED light sources and circulating hydroponics systems. By artificially controlling and simulating the diurnal rhythm, they enable plants to produce efficiently in the microgravity environment of space, providing astronauts with reliable food and oxygen supplies.

[0004] However, existing technologies still have significant shortcomings, such as insufficient uniformity of light and insufficient stability of water supply. The uniformity of light is limited by the layout of lamps and the performance of reflective materials. Light intensity often decreases in the upper and lower layers and edge areas of multi-layer cultivation racks, resulting in uneven plant growth. Plant water supply mainly uses capillary water supply, but fluctuations in pipeline pressure can easily cause uneven liquid supply. Therefore, a solar greenhouse for aerospace cultivation is proposed to solve the above problems. Summary of the Invention

[0019] Compared with the prior art, the present invention provides a solar greenhouse for aerospace planting, which has the following beneficial effects:

[0020] 1. This aerospace-grade solar greenhouse uses a rotating mechanism to drive multiple planting devices to move continuously. In conjunction with fluorescent lamps, it achieves uniform light exposure for the plants. To ensure that the planting devices are always facing upwards, a pressurizing mechanism and two worm gear assemblies work together to ensure that the planting devices are always facing upwards to achieve sufficient and uniform light exposure for the plants, and to achieve a stable water supply to ensure stable plant growth.

[0021] 2. This aerospace-grade solar greenhouse improves water resource utilization by combining ventilation ducts and a recycling mechanism. As plants transpire, water is lost from their surface to the air in the form of water vapor. By drawing air into the recycling mechanism, the large temperature difference causes the water vapor to condense into water droplets. The rotation of the condensation component, in conjunction with the pumping component, extracts the water for subsequent recycling and reuse, thereby improving water resource utilization.

[0022] 3. This aerospace-grade solar greenhouse uses a MEMS inertial measurement unit to monitor the attitude of the planting rack, and works with a drive motor and turbine assembly to adjust the attitude of the planting rack, thereby improving the stability of the device.

Detailed Implementation

[0029] 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.

[0030] Please see Figures 1 to 3 This embodiment of a space-use greenhouse includes a greenhouse body 1. A fluorescent lamp 2 is fixed to the inner top wall of the greenhouse body 1, which can provide sufficient and stable light for the plants. Two support rods 3 are fixed to the inner bottom wall of the greenhouse body 1. The two support rods 3 are used to provide support for the rotating mechanism 4. A rotating mechanism 4 that improves the uniformity of light is provided on the opposite side of the two support rods 3. Multiple planting devices 5 that can plant plants are provided on the inner side of the rotating mechanism 4. A water supply component 6 that extends to the outside of the greenhouse body 1 is provided on the inner side of the rotating mechanism 4. An exhaust pipe 7 is fixedly connected to the top of the greenhouse body 1. The exhaust pipe 7 can ensure that the air flows smoothly into the recovery mechanism 8. A recovery mechanism 8 that can cause the moisture in the air to condense into water droplets is provided on the side of the exhaust pipe 7 away from the greenhouse body 1. A water pumping component 9 that effectively collects water droplets is provided on the right side of the recovery mechanism 8.

[0031] In addition, the rotating mechanism 4 includes a servo motor 401 fixed to the top of the support rod 3 on the left side. The servo motor 401 can provide stable power for the rotation of the rotating frame 402. The rotating frame 402 is rotatably connected between the two support rods 3 through bearings. The bearings play a supporting role and ensure the stable rotation of the rotating frame 402. A driven internal gear 404 is fixed on the side of the rotating frame 402 near the servo motor 401. A driving gear 403 that meshes with the inner side of the driven internal gear 404 is fixed on the outer surface of the output shaft of the servo motor 401. Through the cooperation of the driving gear 403 and the driven internal gear 404, the power of the servo motor 401 can be smoothly and stably transmitted to the rotating frame 402.

[0032] In addition, each planting device 5 includes a planting frame 501 that is rotatably connected to the inner side of the rotating frame 402 via a bearing. The bearing can improve the stability of the rotation of the planting frame 501. Each planting frame 501 is equipped with a pressurizing mechanism 502. Each telescopic planting frame 501 has a MEMS inertial measurement unit 503 fixed on its top. The MEMS inertial measurement unit 503 is an STMicroelectronics LSM6DSO. Each planting frame 501 has multiple partitions 504 fixed on its inner side. The partitions 504 serve to separate the plants and prevent their roots from tangling. Each planting frame 501 has a drain pipe 506 fixedly connected to its right side. Each planting device 5 also includes two turbine assemblies 505. When the two turbine assemblies 505 rotate, they can keep the planting device 5 in a stable state.

[0033] It should be further explained that each planting rack 501 is provided with a pressurizing chamber and a return chamber. Each pressurizing mechanism 502 includes a drive motor 5021 fixed to the left wall of the pressurizing chamber. The drive motor 5021 provides power to rotate the turbine assembly 505 located on the left side. When water flows through the turbine assembly 505, it is thrown outward, achieving a pressurizing effect on the water flow. At the same time, the turbine assembly 505 can ensure that the posture of the planting rack 501 tends to be stable. A baffle plate 5022 is fixed inside the pressurizing chamber. The output shaft of the drive motor 5021 passes through the baffle plate 5022 and is fixed to the turbine assembly 505. Each planting rack 501 has a baffle plate 5022 fixed on its left side, extending into the pressurizing chamber and passing through the turbine assembly 505. The water inlet pipe 5023 passes through the barrier plate 5022. The barrier plate 5022 is used to block the water flow and prevent the water flow from affecting the normal operation of the drive motor 5021. The right side of the pressurization chamber is fixedly connected to the connecting pipe 5024. The right side of the connecting pipe 5024 is fixedly connected to the water supply pipe 5025 extending into the return chamber. The top of the water supply pipe 5025 is fixedly connected to multiple branch pipes 5026 extending into the inside of the planting rack 501. Each branch pipe 5026 is fixedly equipped with a micro valve. By controlling the micro valve, the water flow in each branch pipe 5026 can be controlled to prevent excessive watering from causing root rot in the plants. The drain pipe 506 extends into the return chamber and is connected to the return chamber.

[0034] Furthermore, each turbine assembly 505 includes a rotating rod 5051, with multiple blades 5052 fixed to its outer surface. When the rotating rod 5051 rotates, it drives the multiple blades 5052 to rotate, which in turn drives the counterweight cylinder 5053 to rotate. The counterweight cylinder 5053 is fixed to the side of the multiple blades 5052 away from the rotating rod 5051. The counterweight cylinder 5053 is relatively heavy, and when it rotates, it has a large inertia, which ensures that the planting device 5 remains stable and upward. To further ensure stable illumination of the plants by the fluorescent lamp 2, the rotating rod 5051 on the left side is fixed to the output shaft of the drive motor 5021. The drive motor 5021 outputs power to the rotating rod 5051, causing the rotating rod 5051 to rotate stably. The right side of the rotating rod 5051 on the left side is rotatably connected to the right side wall of the pressurization chamber through a bearing. The rotating rod 5051 on the right side is rotatably connected to the right side wall of the return chamber through a bearing. The bearing plays a supporting role and can ensure the stable rotation of the rotating rod 5051.

[0035] In addition, the water supply component 6 includes a stable pipe 601 fixed to the left side wall of the greenhouse body 1. A water pump is fixedly connected to the end of the stable pipe 601 away from the greenhouse body 1. A sewage treatment device is fixedly connected to the side of the water pump away from the stable pipe 601. The stable pipe 601 passes through the left side wall of the greenhouse body 1 and the left support rod 3 in sequence. A rotating pipe 602 is fixed to the left side of the rotating frame 402, passing through the left side wall of the rotating frame 402. A return pipe 603 is fixed to the right side of the rotating frame 402, passing through the right side wall of the rotating frame 402. The return pipe 603 is used to collect wastewater from multiple planting devices 5 and discharge it into the water pipe 604. A water pipe 604 is fixed to the right support rod 3, passing through the support rod 3. The side of the water pipe 604 away from the right support rod 3 passes through the greenhouse body 1. The side of the water pipe 604 away from the greenhouse body 1 is fixedly connected to the sewage treatment device.

[0036] It should be further explained that the stabilizing pipe 601 extends into the rotating pipe 602 and is rotatably connected to the rotating pipe 602 via a bearing. Since the rotating pipe 602 rotates with the rotating frame 402, while the stabilizing pipe 601 needs to remain stationary, in order to ensure that the water can be transported normally and stably, the stabilizing pipe 601 needs to extend into the rotating pipe 602 and be rotatably connected to the rotating pipe 602 via a bearing. Each inlet pipe 5023 extends into the rotating pipe 602 and is rotatably connected to the rotating pipe 602 via a bearing. The right side of each drain pipe 506 extends into the return pipe 603 and is rotatably connected to the return pipe 603 via a bearing. Similarly, since the planting frame 501 is rotating relative to the rotating frame 402, a bearing is needed to connect and ensure that the water flow is smooth. The left side of the flow pipe 604 extends into the return pipe 603 and is rotatably connected to the return pipe 603 via a bearing.

[0037] In this embodiment, the rotating mechanism 4, the planting device 5 and the fluorescent lamp 2 work together to provide uniform light to the plants. The drive motor 5021 drives the turbine assembly 505 to circulate water, and the turbine assembly 505 pressurizes the water to accelerate the flow, thus smoothly injecting water into the culture medium. The water flow will then cause another turbine assembly 505 to rotate, further improving the stability of the planting rack 501.

[0038] Please see Figure 4 and Figure 5To improve water resource utilization, the recycling mechanism 8 in this embodiment includes a box 801 fixedly connected to the side of the exhaust duct 7 away from the greenhouse body 1. A stepper motor 802 is fixedly mounted on the top of the box 801. The stepper motor 802 drives the output gear 803 to rotate, which in turn drives the condensation component 805 inside the rotating gear 804 to rotate together. The output shaft of the stepper motor 802 passes through the top wall of the box 801. The output gear 803 is fixedly mounted on the outer surface of the output shaft of the stepper motor 802 and inside the box 801. The rotating gear 804 meshes with the right side of the output gear 803. The condensation component 805 is provided inside the rotating gear 804. A stabilizing plate 806 is fixed to the inner wall of the box 801. The stabilizing plate 806 can improve the stability of the condensation component 805. The stabilizing plate 806 has multiple ventilation holes, which facilitates air circulation. The condensation component 805 passes through the stabilizing plate 806 and extends into the box 801. On the outer side of the left side wall, a water storage cover 807 is fixedly connected to the outer side of the box 801. Multiple capillary pores 808 are formed on the inner side wall of the box 801, communicating with the inner cavity of the water storage cover 807. These capillary pores 808 absorb water droplets adhering to the side wall of the box 801. The principle of water droplet absorption by the capillary pores 808 is capillary action. Two support plates 809 are fixed to the bottom of the box 801. These two support plates 809 provide good stability to the box 801 and support the air extraction process. Pump 810 is fixed on the right side of the left support plate 809. The top of the pump 810 is fixedly connected to the bottom of the box 801. An exhaust pipe is fixed on the side of the pump 810 away from the box 801. A gas processing device is fixedly connected on the side of the exhaust pipe away from the pump 810. An air inlet pipe is fixedly connected on the side of the gas processing device away from the pump 810. The air inlet pipe is fixed to the left side wall of the greenhouse body 1 and extends into the greenhouse body 1.

[0039] Furthermore, the condenser assembly 805 includes a drain pipe 8051 fixed to the inner side of the rotating gear 804. The top of the drain pipe 8051 is rotatably connected to the inner top wall of the housing 801 via a bearing. A cold liquid pipe 8052 is fixed to the inner top wall of the drain pipe 8051. The cold liquid pipe 8052 is a vacuum-insulated pipe with a structure of double-layer stainless steel pipe walls with vacuum between them, filled with aerogel or glass fiber core material, providing good insulation and low thickness. Multiple condenser pipes 8053 that penetrate the drain pipe 8051 are fixedly connected to the outer side of the cold liquid pipe 8052. The cold liquid pipe 8052 consists of a straight pipe and a bent pipe. The straight pipe is fixed to the inner top wall of the drain pipe 8051 and penetrates the fixed pipe 8054. The bottom of the straight pipe, located outside the fixed pipe 8054, is connected to the bent pipe via a bearing. The connecting and bending pipes penetrate the left side wall of the housing 801. The other end of each condenser pipe 8053 is fixedly connected to the drain pipe 8051. The drain pipe 8051 extends into the stabilizing plate 806 and is rotatably connected to the stabilizing plate 806 via a bearing. The outer surface of the drain pipe 8051 and located inside the stabilizing plate 806 is rotatably connected to the fixed pipe 8054 via a bearing. Since the drain pipe 8051 needs to rotate while the fixed pipe 8054 cannot rotate, a bearing connection is required between the two to ensure that the coolant can be smoothly delivered. The fixed pipe 8054 extends out of the stabilizing plate 806 and penetrates the left side wall of the housing 801. The coolant pipe 8052 penetrates the fixed pipe 8054, and the side of the coolant pipe 8052 away from the fixed pipe 8054 penetrates the left side wall of the housing 801.

[0040] In addition, the water pumping assembly 9 includes a water pump 902 fixed to the right side wall of the housing 801. The top of the water pump 902 is fixedly connected to a water pumping pipe 901 that penetrates the side wall of the water storage tank 807 and is connected to the inner cavity of the water storage tank 807. The water pump 902 can pump out the liquid in the water storage tank 807 through the water pumping pipe 901.

[0041] In this embodiment, a liquid inlet pump is fixed on the side of the bent pipe away from the straight pipe and outside the housing 801. A cooling device is fixedly connected to the side of the liquid inlet pump away from the bent pipe. A liquid tank is fixedly connected to the side of the cooling device away from the liquid inlet pump. The end of the fixed pipe 8054 away from the housing 801 is fixedly connected to the liquid tank.

[0042] Understandably, the other end of the water pump 902 is connected to the sewage treatment device, and the inner bottom wall of the housing 801 is provided with a conical hole that is connected to the air pump 810. The inner bottom wall of the housing 801 is fixed with a barrier net that is connected to the conical hole. The barrier net can block large solid particles and improve the service life of the air pump 810.

[0043] 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.

[0044] The working principle of the above embodiments is as follows:

[0045] (1) When in use, the plants and their culture medium are placed on the planting rack 501. Multiple partitions 504 can separate the plants smoothly. When light is needed, the servo motor 401 is started, and the driven internal gear 404 is driven to rotate through the active gear 403, which further causes the rotating rack 402 to rotate, so that multiple planting devices 5 revolve around the rotation center of the rotating mechanism 4. At the same time, the drive motor 5021 is started, and the drive motor 5021 drives the turbine assembly 505 to rotate. Due to the effect of the counterweight cylinder 5053, the turbine assembly 505 has a large moment of inertia when it rotates. By utilizing the law of conservation of angular momentum, the planting rack 501 is always facing upward, ensuring that the plants can be fully and evenly irradiated by the fluorescent lamp 2.

[0046] (2) When water supply is required, water is injected into the stable pipe 601. The water flows from the stable pipe 601 through the rotating pipe 602 and the inlet pipe 5023 into the turbine assembly 505 on the left. As the drive motor 5021 drives the blades 5052 to rotate, the water is pressurized and flows through the connecting pipe 5024 into the water supply pipe 5025. The branch pipe 5026 pumps the water into the culture medium to supply water to the plants. At the same time, the micro valve can prevent the plants from being over-watered. The water will flow into the turbine assembly 505 on the right, causing the turbine assembly 505 on the right to rotate, further improving the stability of the device.

[0047] (3) The gas in the greenhouse body 1 is drawn into the box 801 through the exhaust pipe 7 by the exhaust pump 810. At the same time, the stepper motor 802 is started, and the power is output to the condensing component 805 through the output gear 803 and the rotating gear 804, causing the condensing component 805 to rotate. When the gas passes through the condensing component 805, due to the large temperature difference, the moisture in the gas will turn into water droplets and adhere to the condensing tube 8053. When the condensing tube 8053 rotates, it will throw the water droplets onto the inner wall of the box 801. At this time, the capillary pores 808 can absorb the water droplets into the water storage hood 807. The water is then extracted by the water pump 902 for subsequent recycling.

[0048] 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.
