Description

Technical Field

[0001] This utility model relates to the field of plant factory technology, specifically to a plant factory with a ventilation system. Background Technology

[0002] Plant factories are highly efficient agricultural production systems that autonomously control environmental conditions such as light, temperature, water, air, and fertilizer in a fully enclosed environment. They overturn the traditional agricultural production model that relies on sunlight and soil, and can achieve continuous and uninterrupted plant production throughout the year.

[0003] The air environment control system, or ventilation system, plays a crucial role in plant factories. It optimizes plant growth conditions by precisely controlling environmental factors such as temperature, humidity, and carbon dioxide concentration, thereby improving crop yield and quality. The design and optimization of a plant factory's ventilation system involves multiple considerations, including airflow velocity, airflow path, and air exchange frequency. Due to factors such as the stacking of multiple layers of crops, the resistance of crops to airflow, and the heat generated by grow lights, controlling and optimizing the plant growth environment in plant factories faces numerous challenges. Improperly designed air circulation systems can lead to uneven environmental conditions within and between different growth layers, causing some plant growth areas to be overheated or undercooled, or have excessively high or low humidity, thus affecting crop growth rate, yield, and quality.

[0004] In existing plant factories, gaps are typically created between the plant cultivation racks and the side wall ventilation system to facilitate maintenance and management, allowing each cultivation area on the rack to be interconnected on the ventilation side. In this case, when using low ventilation for side wall ventilation, the airflow to the current layer is affected by the airflow from adjacent upper and lower cultivation areas, resulting in turbulent airflow and inconsistent airflow volumes at different cultivation levels, leading to an uneven distribution of the cultivation environment along its height. Therefore, most plant factories use high ventilation to ensure good ventilation to the cultivation area at the center of the ventilation openings, thus guaranteeing the uniformity of the environment across the vertically distributed cultivation areas on the racks. However, high ventilation corresponds to high energy consumption. Furthermore, due to excessive ventilation, plants near the airflow side experience wind stress, resulting in excessive transpiration rates, affecting plant growth rate, yield, and quality, and in extreme cases, even causing plant wilting.

[0005] Therefore, there is an urgent need for a plant factory with good environmental uniformity under low ventilation to reduce energy consumption and cost while improving plant growth rate, yield and quality. Utility Model Content

[0006] The purpose of this invention is to propose a plant factory with ventilated sidewalls, which solves the problem in the prior art that the ventilation volume of existing plant factories is too high, resulting in excessive energy consumption, high cost, and affecting the growth rate, yield and quality of plants.

[0007] To achieve the above objectives, this utility model proposes a plant factory with ventilated side walls, including a box body, with at least one set of cultivation modules inside the box body, wherein each set of cultivation modules includes a plant cultivation rack, a ventilated side wall and multiple partitions.

[0010] Optionally, the ventilation sidewall is also provided with multiple sets of air supply structures, each set of air supply structures is located between two adjacent partitions and corresponds to the plant cultivation area, so that the gas delivered by each air supply structure flows independently in the connected plant cultivation area.

[0011] Optionally, a water tank is also installed on the frame, which is located below the plant cultivation board; the top of the plant cultivation board has a groove for placing cultivation containers; the top surface of the plant cultivation board at the top of the frame is in contact with the top surface of the inner cavity of the box.

[0012] Optionally, the air supply structure is a strip-shaped vent on the ventilation sidewall, and multiple air supply structures are distributed along the height of the ventilation sidewall; the airflow direction at the opening of the air supply structure is consistent with the length direction of the plant light.

[0013] Optionally, the box is also equipped with at least one set of return air structures, each set of return air structures being located on the open side of the plant cultivation area.

[0014] Optionally, the return air structure includes return air inlets that are evenly spaced at the top of the enclosure along the length of the ventilation sidewall.

[0015] Optionally, the separator includes a partition installed on the ventilation side wall and a buffer strip installed on the partition that contacts the plant cultivation board. The partition separates adjacent air supply structures, allowing the gas output by the air supply structure to flow independently within the corresponding plant cultivation area.

[0016] Optionally, the partition includes a partition body and a telescopic partition movably mounted on the partition body. The telescopic partition and the partition body are provided with a telescopic guide structure. A limiting structure connected to the telescopic guide structure is provided on the ventilation side wall.

[0017] Optionally, the buffer strip is installed on the side of the telescopic partition away from the main body of the partition.

[0018] Optionally, the telescopic guide structure includes a telescopic groove provided on the main body of the partition, guide grooves provided on both sides of the main body of the partition and connected to the telescopic groove, guide blocks installed on both sides of the telescopic partition and located in the guide grooves, mounting columns installed in the guide grooves, and springs fitted on the mounting columns and in contact with the guide blocks.

This ensures that when the air supply structure on the ventilated sidewalls is supplying air, the airflow in adjacent plant cultivation areas will not affect each other. This allows the air supply structure to maintain the uniformity of the environment in each plant cultivation area even with low ventilation volume, thereby reducing energy consumption, reducing wind stress on plants near the air supply outlet, and ensuring plant growth rate, yield, and quality.

[0037] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the present invention. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] The plant factory with ventilated sidewalls described in this application can be used for ventilation in plant factories and other similar applications. The following is a detailed description of a plant factory with ventilated sidewalls.

[0039] Example 1

[0040] See appendix Figure 1 — Figure 7The diagram shows a preferred embodiment of a plant factory with a ventilated sidewall according to this application. The plant factory with a ventilated sidewall includes a housing 1, within which at least one set of cultivation modules is provided. Each cultivation module includes a plant cultivation rack 2, a ventilated sidewall 3, and multiple partitions 4. The plant cultivation rack 2 includes multiple layers of plant cultivation boards 22 for placing cultivation containers. The ventilated sidewall 3 is located on one side of the plant cultivation rack 2 and is perpendicular to the plant cultivation boards 22. One end of each partition 4 is mounted on the ventilated sidewall 3, and the other end abuts against one end of the plant cultivation board 22. The ventilated sidewall 3 also has multiple sets of air supply structures 31, each set of air supply structures 31 located between two adjacent partitions 4 and corresponding to a plant cultivation area 24, so that the gas supplied by each air supply structure 31 flows independently within the interconnected plant cultivation area 24.

[0041] This invention uses the housing 1 to separate the plant cultivation rack 2 from the external environment, reducing the impact of the external environment on plant growth; the plant cultivation rack 2 provides a place to support the cultivation containers; the air supply structure 31 allows for low-volume air intake to ventilate the housing 1 and the plants, ensuring normal plant growth; the partition 4, together with the ventilated side wall 3 and adjacent plant cultivation boards 22, prevents the gases delivered by the air supply structure 31 at different heights from interfering with each other, thus avoiding air turbulence. This allows the air supply structure 31 to use low ventilation to reduce energy consumption while increasing plant growth rate, ensuring plant production and quality.

[0042] See appendix Figure 2 — Figure 6 As shown, in this utility model, the plant cultivation rack 2 includes a frame 21, a plant cultivation board 22 installed on the frame, and a plant light 23 installed at the bottom of the plant cultivation board 22 and located at the top of the plant cultivation area 24; wherein, adjacent plant cultivation boards 22, together with the ventilation side wall 3 and the partition 4, form a plant cultivation area 24 that is closed on one side, the plant light 23 is located above the plant cultivation area 24, and a water tank 25 is also installed on the frame 21, which is located below the plant cultivation board 22.

[0043] This utility model provides an installation position for the plant cultivation board 22 through the setting of the frame 21; provides a place for the plants through the setting of the plant cultivation board 22; provides light for the plants through the setting of the plant light 23; and ensures water and fertilizer circulation in the cultivation area through the setting of the water tank 25.

[0044] See appendix Figure 2 — Figure 5 As shown, in this utility model, the top of the plant cultivation board 22 is provided with a groove 221, and the top surface of the plant cultivation board 22 located at the top of the frame 21 is in contact with the top surface of the inner cavity of the box 1.

[0045] This invention, through the groove 221, limits the placement of the cultivation container, preventing it from shifting or falling during the movement of the plant cultivation rack 2, thus ensuring stable placement. It should be noted that casters can be installed at the bottom of the rack 21, ensuring the plant cultivation rack 2 can be moved. This allows for easy replacement of the plant cultivation rack 2 after the plants have grown, improving operational efficiency. Furthermore, the mobility of the plant cultivation rack 2 increases the possibility of a gap between it and the ventilation side wall 3, facilitating maintenance of the ventilation side wall 3.

[0046] See appendix Figure 2 and Figure 7 As shown, in this utility model, the air supply structure 31 is a strip-shaped ventilation opening opened on the ventilation side wall, and multiple air supply structures 31 are distributed along the height direction of the ventilation side wall 3; the air flow direction at the opening of the air supply structure 31 is consistent with the length direction of the plant light 23.

[0047] This invention utilizes strip-shaped ventilation openings to allow air to escape, creating airflow. The airflow direction at the opening of the ventilation openings aligns with the length of the plant light 23, preventing the plant light from obstructing the airflow and minimizing its impact, thus ensuring uniform airflow. It is important to note that the air supply structure 31 is located between the two plant cultivation plates 22, and the number of air supply structures 31 is equal to the number of plant cultivation areas 24. Combined with the separator 4, this ensures that each plant cultivation area 24 is only affected by the ventilation of one air supply structure 31, thereby preventing adjacent air supply structures 31 from interfering with each other.

[0048] See appendix Figure 4 As shown, in this utility model, the box body 1 is also provided with no less than one set of return air structures 5. Each set of return air structures 5 is located on the open side of the plant cultivation area 24. The return air structure 5 includes return air inlets 51 that are equally spaced along the length of the ventilation side wall 3 at the top of the box body 1.

[0049] This utility model, through the setting of the return air vent 51, allows air to be discharged from the box 1, ensuring airflow within the box 1 while maintaining other stability. It should be noted that an air inlet pipe is installed on the ventilation side wall 3, which is connected to the strip-shaped ventilation opening of the air supply structure 31, providing ventilation to the air supply structure 31. The air inlet pipe is also connected to external ventilation equipment, and an exhaust device can be installed at the return air vent 51 to guide the airflow direction within the box 1. The external ventilation equipment is prior art, therefore it will not be described in detail in this application.

[0050] See appendix Figure 7As shown, in this utility model, the separator 4 includes partitions 41 that are installed at equal intervals on the ventilation side wall 3, and buffer strips 42 that are installed on the partitions 41 and in contact with the plant cultivation board 22.

[0051] This invention uses a partition 41 to separate adjacent air supply structures 31, independently isolating adjacent plant cultivation areas 24. This closes one side of the plant cultivation areas 24, preventing them from communicating with each other on the side closest to the ventilation sidewall 3, ensuring that the air circulating within the plant cultivation areas 24 does not interfere with each other. Simultaneously, it provides an installation location for the buffer strip 42. The buffer strip 42 further improves the sealing of the partition 41, ensuring that the air in adjacent plant cultivation areas 24 does not interfere with each other, and buffers the contact between the plant cultivation rack 2 and the partition 41, providing cushioning protection when the moving plant cultivation rack 2 collides with the partition 41.

[0052] See appendix Figure 1 — Figure 7 As shown, the usage process of this utility model is as follows:

[0053] Place the plant cultivation rack 2 in the designated position, ensuring that the side of each plant cultivation board 22 on the plant cultivation rack 2 contacts the buffer strip 42 in the partition 4, so that the side of the plant cultivation area 24 near the ventilation side wall 3 is closed; therefore, when the air supply structure 31 ventilates into the box 1, each air supply structure 31 is blocked by the partition 4 and can only ventilate one plant cultivation area 24 connected to it, and cannot affect other plant cultivation areas 24, ensuring that there is only one gas flow direction in each plant cultivation area 24, so that the ventilation volume of each plant cultivation area 24 is independent of each other, ensuring that low ventilation volume can be used to reduce energy consumption, reduce plant transpiration rate, and ensure plant growth rate, yield and quality.

[0054] Example 2

[0055] See appendix Figure 8 — Figure 12 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, the partition 41 includes a partition body 411 and a telescopic partition 412 movably installed on the partition body 411. The telescopic partition 412 and the partition body 411 are provided with a telescopic guide structure 43; the ventilation side wall 3 is provided with a limiting structure 44 connected to the telescopic guide structure 43; and the buffer strip 42 is installed on the side of the telescopic partition 412 away from the partition body 411.

[0056] In this embodiment, the partition body 411 and the telescopic partition 412 are configured so that the telescopic partition 412 can move telescopically relative to the partition body 411. This allows the telescopic partition 412 to adaptively adjust according to the distance between the plant cultivation rack 2 and the ventilation side wall 3, ensuring that adjacent plant cultivation areas 24 can be separated. The telescopic guide structure 43 is used to guide the telescopic movement of the telescopic partition 412. The limiting structure 44 is used to limit the telescopic partition 412 in the retracted state.

[0057] See appendix Figure 8 — Figure 12 As shown, in this utility model, the telescopic guide structure 43 includes a telescopic groove 431 disposed on the partition body 411, a guide groove 432 disposed on both sides of the partition body 411 and connected to the telescopic groove 431, a guide block 433 installed on both sides of the telescopic partition 412 and located in the guide groove 432, a mounting post 434 installed in the guide groove 432, and a spring 435 fitted on the mounting post 434 and in contact with the guide block 433.

[0058] In this embodiment, the telescopic groove 431 provides space for the telescopic partition 412 to extend and retract, allowing the telescopic partition 412 to move. The guide groove 432, in conjunction with the guide block 433, provides guidance for the telescopic partition 412 to extend and retract. The mounting column 434 provides installation conditions for the spring 435. The spring 435 pushes the guide block 433 to move, causing the telescopic partition 412 to extend.

[0059] See appendix Figure 12 As shown, the limiting structure 44 includes a limiting post 441 installed on the ventilation side wall 3 and a limiting tube clamp 442 installed on the limiting post 441.

[0060] In this embodiment, the setting of the limiting post 441 provides an installation position for the limiting tube clamp 442; the setting of the limiting tube clamp 442 limits the guide block 433 and prevents the guide block 433 from extending due to the elastic force of the spring 435.

[0061] See appendix Figure 8 — Figure 12 As shown, in this utility model, the width of the telescopic groove 431 is greater than the width of the telescopic partition 412; the cross-section of the guide block 433 is square, and a limiting cylinder 436 is installed on the guide block 433. The limiting cylinder 436 cooperates with the limiting tube clamp 442.

[0062] In this embodiment, by limiting the width of the expansion groove 431, and by making the width of the expansion groove 431 greater than the width of the expansion partition 412, the expansion partition 412 can be placed at an angle within the expansion groove 431, ensuring that it is in close contact with the side of the plant cultivation board 22 on the plant cultivation rack 2. Even if the distance between the plant cultivation rack 2 and the ventilation side wall 3 changes, a plant cultivation area 24 can be formed with one side closed, ensuring independent airflow within each plant cultivation area 24.

[0063] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
