[0018] Example 1 This utility model discloses a containerized multifunctional plant factory, including: a container module 100 and a central controller 200.

[0019] The container module 100 is a 40HQ standard container, with an internal length of 12.032 meters, a width of 2.352 meters, and a height of 2.69 meters. Photovoltaic solar panels are installed on the top of the container module 100 to serve as the power source for the multifunctional plant factory system.

[0020] The internal space of the container module 100 is equipped with a vertical tiered seedling rack 110, a vertical tiered cultivation rack 120, an environmental control system, and a water and fertilizer integrated circulation supply device 140.

[0021] Specifically, the vertical tiered seedling rack 110 has a 4-layer three-dimensional structure with a layer spacing of 20-30cm, preferably 25cm. The vertical tiered cultivation rack 120 has a 4-layer three-dimensional structure with a layer spacing of 40-50cm, preferably 45cm.

[0022] Both the vertical tiered seedling rack 110 and the vertical tiered cultivation rack 120 are constructed from 3030 aluminum alloy profiles, offering advantages such as low cost and easy assembly. The design and use of these racks improve the space utilization efficiency of the container module, effectively expanding the planting area per unit volume, significantly increasing productivity per unit area, directly reducing land and space costs, and laying the foundation for efficient and intensive production.

[0023] The vertical tiered seedling rack 110 and the vertical tiered cultivation rack 120 are arranged alternately. In this embodiment, as shown... Figure 1 As shown, the vertical tiered seedling rack 110 and the vertical tiered cultivation rack 120 are respectively placed against the wall on both sides of the container module 100 for easy management.

[0024] Each layer of the vertical tiered seedling rack 110 and the vertical tiered cultivation rack 120 is equipped with a cultivation trough 150, and the bottom of the cultivation trough 150 has a nutrient solution flow hole 151 with a diameter of 5mm.

[0025] The environmental control system includes a plant active light source 131, an air conditioner (not shown), a fan (not shown), a CO2 supply device (not shown), a temperature and humidity sensor (not shown), a CO2 sensor (not shown), a light sensor (not shown), and a nutrient solution EC value sensor (not shown).

[0026] The plant active light source 131 is installed on the inner top of the container module 100 and on the top of each layer of the vertical tiered seedling rack 110 and the vertical tiered cultivation rack 120, to provide sufficient light intensity and duration for plant growth.

[0027] The air conditioner, fan, and CO2 supply device are installed in the equipment compartment at one end of the container module 100 and are connected to the space where the vertical multi-layer cultivation rack and vertical multi-layer seedling rack are located. The temperature and humidity sensor, CO2 sensor, and light sensor are installed on the telescopic support frame 300 in the space where the vertical multi-layer seedling rack 110 and vertical multi-layer cultivation rack 120 are located, for real-time detection of temperature and humidity, CO2 concentration, and light intensity in the seedling-cultivation space. The telescopic support frame 300 is driven by a stepper motor, which facilitates the lifting and adjusting of the positions of the temperature and humidity sensor, CO2 sensor, and light sensor to detect temperature, humidity, CO2 concentration, and light intensity at different spatial heights, thereby improving the accuracy of the detection results.

[0028] The integrated water and fertilizer circulation supply device 140 includes a water supply pump 141, a nutrient solution storage tank 142, a water storage container 143, and a return water pump 144.

[0029] Specifically, one end of the water supply pump 141 is connected to the nutrient solution storage tank 142 via a pipe, and the other end is connected to the cultivation troughs of each layer of the vertical tiered seedling rack 110 and the vertical tiered cultivation rack 120 via a main water supply pipe 145 and a branch water supply pipe 146, respectively. The main water supply pipe 145 comprises multiple pipe sections, with its initial section connected to the water supply pump 141 and its final section vertically arranged at one end of the vertical tiered seedling rack 110 and the vertical tiered cultivation rack 120. The branch water supply pipes 146 are distributed between the layers of the seedling rack and the cultivation rack, including a first branch water supply pipe section 1461 and a second branch water supply pipe section 1462. The first branch water supply pipe section 1461 is connected to the main water supply pipe 145 and is equipped with a switch valve, while the second branch water supply pipe section 1462 is horizontally positioned or penetrates the cultivation trough 150. The second water supply pipe section 1462 has water distribution holes on its bottom and side for supplying water to the cultivation trough 150, thereby improving water resource utilization.

[0030] The water storage container 143 is connected to the cultivation trough 150 via a return water pipe 147.

[0031] Specifically, the nutrient solution flow hole 151 of the cultivation trough 150 is connected to a return water branch pipe 152. The return water branch pipe 152 is connected to the return water pipe 147, and the return water pipe 147 is connected to the water storage container 143, so that excess nutrient solution in the cultivation trough 150 flows through the return water branch pipe 152 to the return water pipe 147, and then flows back to the water storage container 143.

[0032] The water storage container 143 is also connected to the nutrient solution storage tank 142 via the return water pump 144, allowing the nutrient solution collected and returned in the water storage container 143 to be reused in the nutrient solution storage tank 142, thus saving resources. Specifically, a filter assembly, such as a filter screen or filter, is also provided on the pipeline between the water storage container 143 and the return water pump 144 to purify the nutrient solution flowing through the cultivation trough 150 and prevent contamination of the nutrient solution in the nutrient solution storage tank 142.

[0033] The nutrient solution EC value sensor is installed inside the nutrient solution storage tank 142 to detect the EC value of the nutrient solution in the storage tank in real time. Based on the monitoring results, the corresponding ion solution is added to adjust the EC value of the nutrient solution and ensure the healthy growth of the plants.

[0034] Specifically, the outer top of the container module 100 is equipped with a photovoltaic solar panel that is connected to and powered by the plant active light source 131, the water pump 112 and the CO2 supply device 107, using green energy for power supply, which is energy-saving and environmentally friendly.

[0035] The central controller 200 is connected to the temperature and humidity sensor, CO2 sensor, light sensor, and nutrient solution EC value sensor. It is also connected to the air conditioner, fan, CO2 supply device, plant active light source, and water pump for linkage control through the temperature and humidity sensor, CO2 sensor, light sensor, and nutrient solution EC value sensor. The controller adjusts the opening and closing of the air conditioner, fan, CO2 supply device, and plant active light source in real time according to the received temperature, humidity, carbon dioxide concentration, and light intensity.

[0036] Furthermore, the side wall of the container module 100 is also provided with a rainwater collector 160, which is connected to the nutrient solution storage tank 142 through a pipe. A filter assembly is also provided between the rainwater collector 160 and the nutrient solution storage tank 142 to purify the collected rainwater and prevent contamination of the nutrient solution in the nutrient solution storage tank 142.

[0037] In addition, to adapt to extreme environments, the outer wall of the container module 100 is sequentially laminated with a 6mm thick aerogel layer and a nano-ceramic insulation film with a thermal conductivity ≤0.03W / (m·K), such as 0.02W / (m·K); the inner wall of the container module 100 is laminated with a phase change material layer with a phase change temperature of 25±2℃, in order to optimize energy consumption performance under extreme environments, reduce energy consumption, and make it suitable for extreme environments, such as polar environments at -30℃, thereby improving its applicability in extreme environments.

[0038] In plant cultivation, a single 40HQ container can be used as an independent production unit, suitable for small-scale experiments or demonstrations. The modular design of the single container facilitates rapid deployment.

[0039] Furthermore, the sidewall of the container module 100 is also provided with standard interface holes (not shown). Adjacent container modules 100 are connected by quick-release couplers (consisting of an integrated water and electricity interface and a pneumatic sealing ring) to form a large-scale three-dimensional cultivation substrate. Each container module is equipped with an independent environmental control system, which is controlled by the central controller 200 to improve production scale and efficiency.

[0040] The working principle of the above system is as follows: First, environmental sensors continuously collect data on temperature, humidity, light intensity, and CO2 concentration, transmitting the data to the central controller 200. The central controller 200 then automatically adjusts the spectral intensity and illumination time of the plant-active light source, the operating status of the air conditioner and fan, and the CO2 concentration based on a comparison of the received information with pre-stored information.

[0041] Specifically, when the CO2 sensor detects a concentration of <800ppm, the CO2 supply device is activated; When the temperature and humidity sensor detects a temperature >28℃ and humidity <60%, the air conditioner and fan will start simultaneously. The wavelength combination of the plant's active light source (660nm red light + 450nm blue light) is dynamically adjusted based on data from the light sensor.

[0042] During plant cultivation, the central controller 200 can also use real-time synchronization and simulation of the physical environment and virtual model of the greenhouse to provide early warning of potential environmental anomalies (such as excessively high temperature, low humidity, abnormal CO2 concentration, etc.) and automatically adjust relevant equipment parameters to achieve unmanned and efficient management.

[0043] The containerized multifunctional plant factory described above can be used for the seedling cultivation and planting of stem-leaf or fruit-bearing plants, thereby increasing yield.

[0044] Under the same area, the annual yield of lettuce can reach 480 kg using the above-mentioned single container multifunctional plant factory, compared with the annual yield of 120 kg of traditional single-layer cultivation racks, which increases the space utilization rate by 300%.

[0045] The container-based multifunctional plant factory of this invention has the following advantages: First, by incorporating multi-layer vertical seedling racks and cultivation racks within the container, space utilization efficiency is greatly improved, effectively expanding the planting area per unit volume. Compared to traditional single-layer cultivation or facilities with low space utilization, this significantly increases productivity per unit area, directly reducing land and space costs and achieving highly efficient and intensive production.

[0046] Secondly, it achieves integrated management of multiple functions, including seedling cultivation, planting, environmental control, and water and fertilizer management. All core production processes operate collaboratively within the same closed system, avoiding information silos and management gaps caused by the functional division of traditional facilities. Through an integrated environmental control system and water and fertilizer recycling supply device, it promotes seamless connection between seedling cultivation and planting, reduces energy consumption and management difficulty, and improves overall production efficiency and automation level.

[0047] Third, the equipment uses photovoltaic solar panels to power components such as plant active light sources, air conditioners, fans, CO2 supply devices, and motors, making it green and environmentally friendly; the design of the integrated water and fertilizer circulation supply device improves the utilization rate of water resources.

[0048] Fourth, adopting a standardized and modular design concept, the container modules and their internal structures can be customized and expanded as needed. The connections between functional units are simple, facilitating disassembly, assembly, and maintenance, which not only reduces construction and operation costs but also facilitates large-scale production and rapid deployment in different locations. Compared to traditional facilities with complex structures and a lack of standard interfaces, this system has higher replicability and promotional value.

[0049] Fifth, the system integrates multi-parameter environmental sensors and a central controller, enabling real-time monitoring, analysis, and automatic control of key parameters such as temperature, humidity, light intensity, and CO2 concentration. Through data-driven precision management, it effectively avoids environmental fluctuations caused by the lag in manual monitoring, ensuring the continuity and consistency of crop growth. The resulting high level of automation and intelligence continuously improves product quality and yield, while simplifying management processes.

[0050] Sixth, due to the container's excellent airtightness and mobility, combined with thermal insulation layers and intelligent environmental control equipment, it can adapt to various extreme environments such as deserts, plateaus, and polar regions. Compared to traditional facility agriculture that relies on natural climate or geographical conditions, this utility model breaks through environmental limitations and provides a feasible solution for efficient vegetable production in various scenarios such as cities and remote areas, helping to achieve stable supply and emergency protection throughout the year.

[0051] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
