Description

Technical Field

[0001] This application relates to the field of agricultural planting technology, and in particular to an agricultural building unit. Background Technology

[0002] Agricultural activities in harsh environments such as arid deserts, high-altitude permafrost, and saline-alkali tidal flats generally face constraints from energy consumption and ecological fragility. For example, in desert areas, the efficiency of livestock farming is severely restricted by environmental factors such as high temperatures and drought. In high-temperature environments, the feed intake of fattening pigs can decrease by 20% to 40%, and the conception rate of sows decreases while the risk of stillbirth increases. Secondly, agricultural cultivation in high-temperature environments usually relies on greenhouse control. However, due to the large diurnal temperature range in desert areas, achieving temperature control in greenhouses would generate huge energy consumption, leading to an imbalance between energy input and crop output, making it unsuitable for widespread adoption. Summary of the Invention

[0018] As an example of this application, the first air vent is arranged at an angle to the ground; the top wall includes a plurality of top light-transmitting films, which are able to be penetrated by sunlight and are movably connected to the first air vent, so that the top light-transmitting films can be opened and closed along the arrangement direction of the first air vent and form a guide surface.

[0019] Compared with existing technologies, the agricultural building unit implemented in this application has the following advantages: This agricultural building unit, through the cooperation of a frame, supporting components, top wall, side wall, and a first barrier, separates the top of the first space from the atmospheric environment with the cooperation of the top wall and the frame. The side wall and supporting components separate the third space from the atmospheric environment, and the first barrier separates the bottom of the first and third spaces from the atmospheric environment. Thus, the agricultural building unit encloses the first and third spaces within the atmospheric environment, forming an environment with a temperature more suitable for agricultural cultivation than the atmospheric environment. In this way, the agricultural building unit of this application can construct an agricultural cultivation space with better environmental conditions in harsh environments such as sandy areas, desert areas, and frigid areas. Therefore, the agricultural building unit of this application can use the first space as the basic environment for agricultural production and construct greenhouses, breeding farms, and non-enclosed cultivation fields in harsh environments.

[0020] Secondly, this agricultural building unit, by configuring its top and side walls to allow visible light to pass through and to reflect or absorb at least one of infrared and ultraviolet light, protects the first and third spaces from direct infrared and ultraviolet radiation, reducing heat accumulation in the first and third spaces due to natural lighting. Furthermore, the first barrier separates the first and third spaces from the external ground, effectively suppressing secondary radiation from the external ground. Moreover, with the cooperation of the top and side walls, under direct sunlight, the first barrier absorbs less solar heat than the external ground, resulting in a temperature significantly lower than the surface temperature under direct sunlight. This reduces long-wave radiation from the first barrier to the first and third spaces, thus lowering their temperatures below atmospheric temperatures. Consequently, the temperature control costs for greenhouses, livestock farms, and open cultivation areas constructed within the first space can be effectively reduced, saving energy consumption during operation.

[0021] Secondly, this agricultural building unit has a vegetation layer arranged on the outer periphery of the side wall through the second barrier. Under the transpiration of the vegetation layer and the evaporation of the water used in the vegetation, the area where the vegetation layer is located can form a local temperature environment with a temperature lower than the ground temperature of the atmospheric environment. Combined with the temperature environment of the third space, the airflow of the atmospheric environment can enter this agricultural building unit from the second air vent and leave this agricultural building unit through the first air vent, thereby forming a bottom-up natural ventilation airflow in the first space. During a certain period of time when the natural ventilation is turned on, the lower temperature air that has settled in the third space and near the first barrier is diffused into the first space, thereby quickly reducing the ambient temperature of the first space. In this way, the temperature control cost of the greenhouse, breeding farm and non-enclosed cultivation field built in the first space can be effectively reduced, saving the operating energy consumption of the greenhouse, breeding farm and non-enclosed cultivation field.

[0022] Secondly, this agricultural building unit, through the vegetation layer adjacent to the second air vent and in conjunction with the third space, can create a dynamically stable localized low-temperature environment similar to a shaded area. The vegetation layer can reduce the wind speed entering this agricultural building unit, significantly slowing down the intrusion of hot air from the external environment. Moreover, when the airflow from the external environment passes through the vegetation layer, it can exchange heat with the vegetation layer, thereby pre-cooling the airflow entering this agricultural building unit, reducing the temperature of the airflow entering this agricultural building unit, and preventing the inflow of external airflow from excessively affecting the temperature environment of the first space.

[0023] Secondly, by setting up support members on the outer periphery of the frame and setting up side walls on the support members, when the agricultural building unit encounters meteorological disasters such as strong winds and sandstorms, the side ventilation members can close the second air vent, making the side walls a guiding surface inclined to the ground, avoiding the first space from being directly affected by meteorological disasters such as strong winds and sandstorms, and ensuring the ecological safety of agricultural production inside the agricultural building unit.

[0026] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0027] In the description of this application, it should be understood that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on that other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to that other element. The terms "mounted," "connected," and "attached" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements or the interaction between two elements. Those skilled in the art will understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] In the description of this application, it should be understood that the terms "height," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0029] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0030] Example 1 refer to Figure 1-10 This application provides an agricultural building unit 100 suitable for marginal land. Marginal land in this embodiment refers to land that is economically on the edge or below the break-even point due to natural conditions (such as harsh climate, barren soil, water shortage, salinization, steep slope, etc.), resulting in high costs, high risks, low and unstable yields for traditional agricultural cultivation, such as desert areas and sandy areas.

[0031] Taking the construction of an agricultural building unit 100 in desert and sandy areas as an example, the agricultural building unit 100 in this embodiment 1 includes a frame 1, supporting components 7, a top wall 5, side walls 9, a first barrier 11, a second barrier 12, and multiple production units 3. The frame 1 can be made of steel structure components, serving as the structural foundation of the agricultural building unit 100. The frame 1 is connected to the ground, and the top and sides of the frame 1 are open. A first space 2 is formed inside the frame 1, and multiple production units 3 are set in the first space 2, located inside the frame 1. Each production unit 3 uses the air in the first space 2 as the gas exchange medium for agricultural production. Each production unit 3 can be one of a greenhouse, a breeding farm, or an open cultivation field. The greenhouse can be an existing enclosed greenhouse structure such as a large greenhouse, a multi-layer greenhouse, a plastic greenhouse, a glass greenhouse, a greenhouse shed, a solar greenhouse, or a heated greenhouse. The open cultivation field can be an unenclosed cultivation field such as an open-field cultivation or a potted cultivation. It should be noted that the first space 2 is the internal space defined by the frame 1 when the frame 1 is connected to the ground.

[0032] It should be noted that, based on the agricultural production needs of this agricultural building unit 100, this agricultural building unit 100 can selectively accommodate greenhouses, livestock farms, and non-enclosed cultivation fields. For example, in some agricultural building units 100, the first space 2 can accommodate multiple greenhouses, multiple livestock farms, or multiple non-enclosed cultivation fields; it can also accommodate one greenhouse and one livestock farm, one non-enclosed cultivation field and one livestock farm, or one non-enclosed cultivation field and one greenhouse. In other agricultural building units 100, the first space 2 can accommodate one greenhouse, one livestock farm, and one non-enclosed cultivation field; it can also accommodate multiple greenhouses, multiple livestock farms, and multiple non-enclosed cultivation fields.

[0033] Considering that this agricultural building unit 100 is used in harsh environments such as deserts and sandy areas, infrared and ultraviolet light can easily cause heat accumulation in the first space 2, thereby affecting the operating energy consumption of the production unit 3. Therefore, this agricultural building unit 100 uses the working area of ​​a greenhouse, breeding farm, or open cultivation field as the second space 3a within the production unit 3, and at least one of the following barrier layers 4, which can be penetrated by visible light and can at least reflect or absorb one of infrared and ultraviolet light, is arranged above the second space 3a. The working area of ​​the greenhouse, breeding farm, or open cultivation field is the area where agricultural cultivation is carried out in the greenhouse, breeding farm, or open cultivation field.

[0034] It is understandable that when agricultural activities are carried out in production unit 3, air exchange is required in the second space 3a to meet the growth needs of the plants and animals within it. Using the air in the first space 2 as the gas exchange medium for agricultural production means that when agricultural activities are conducted in production unit 3, the air in the second space 3a exchanges gas with the air in the first space 2, undergoing convection and exchange. For example, when production unit 3 is a greenhouse, the greenhouse's refrigeration components draw in air from the first space 2 and exhaust air from the second space 3a. When production unit 3 is a farm or an open cultivation area, the farm or cultivation area can be an open space, allowing convection and exchange between the air in the second space 3a and the air in the first space 2.

[0035] It is understandable that most of the heat generated by natural sunlight comes from direct radiation of infrared and ultraviolet light. Therefore, configuring the barrier layer 4 to reflect or absorb either infrared or ultraviolet light can reduce the heat generated by natural sunlight in the second space 3a. In this way, when the agricultural building unit 100 needs to maintain the temperature of the second space 3a at a preset temperature, the energy consumption for maintaining the temperature of the second space 3a can be reduced. This is beneficial for the application of the agricultural building unit 100 in harsh environments such as deserts and sandy lands, reducing agricultural farming costs and solving the problem of low and unstable agricultural yields in marginal land. As an example of this embodiment 1, the barrier layer 4 can be coated with a low-emissivity coating, such as a LOW-E coating, so that the barrier layer 4 can reflect far-infrared light (wavelength > 2500 nm), reflect near-infrared light (wavelength between 780 and 2500 nm), and absorb ultraviolet light (wavelength between 100 and 380 nm), while allowing visible light (wavelength between 380 and 780 nm) to enter the second space 3a.

[0036] It should be noted that since the spectrum is continuous, the endpoints of two adjacent light waves belong to the transition region between the two light waves. For example, light waves with a wavelength of 380nm are in the transition region between visible light and ultraviolet light. Some low-emissivity coatings may absorb such light waves, while other low-emissivity coatings may allow such light waves to enter the second space 3a. Therefore, this agricultural building unit 100 verifies that the barrier layer 4 is penetrated by visible light and at least reflects or absorbs one of the infrared and ultraviolet light. Usually, the endpoints of the wavelength band are not used for verification.

[0037] refer to Figure 1-10In this embodiment 1, the agricultural building unit 100 has a top wall 5. The top wall 5 is connected to the top of the frame 1 to enclose the top of the first space 2. Furthermore, the top wall 5 in this embodiment 1 is constructed as a barrier layer 4. Thus, when natural light enters the first space 2 through the top wall 5, the barrier layer 5 filters infrared and ultraviolet light, allowing visible light to enter the first space 2, thereby providing the necessary light for the growth of plants and animals within the first space 2. Of course, the top wall 5 also has a first vent 6, which is an outlet for natural ventilation to connect the first space 2 with the atmospheric environment, thereby enabling the first space 2 to have a gaseous environment similar to or close to the external atmospheric environment, such as air pressure, oxygen content, and carbon dioxide content.

[0038] In the agricultural building unit 100 of this embodiment 1, the top wall 5 is connected to the top of the frame 1 and forms a roof-like shelter structure on the top of the frame 1 to protect the top of the first space 2 and to shelter the first space 2 and the production unit 3 located in the first space 2 from wind and rain.

[0039] refer to Figure 1-10 In this embodiment 1, the agricultural building unit 100 includes a support member 7. The support member 7 is disposed on the outer periphery of the frame 1, with one end of the support member 7 approaching the top of the frame 1 and connected to it. The other end of the support member 7 is connected to the ground, forming a third space 8 between the portion of the frame 1 connected to the ground and the support member 7. This third space 8 is arranged around the periphery of the first space 2 and on the outer periphery of the frame 1, separating the periphery of the first space 2 from the external environment. It should be noted that the support member 7 has two opposing ends, with the end of the support member 7 near the top of the frame 1 serving as the connecting end. This connecting end can extend to the top of the frame 1 and be directly connected to it. Alternatively, this connecting end can be connected to the top of the frame 1 via a connecting structure; in this case, the connecting end is not directly connected to the top of the frame 1, but only approaches the top of the frame 1.

[0040] refer to Figure 1-10 The side wall 9 is connected to the support member 7, thereby forming a shielding structure similar to an external wall at the support member 7 to enclose the third space 8. Furthermore, the side wall 9 of this embodiment 1 is constructed to allow visible light to pass through and to reflect or absorb at least one of infrared and ultraviolet light. Thus, in the agricultural building unit 100 of this embodiment 1, the side wall 9 and the top wall 5 cooperate to effectively block infrared / ultraviolet light from entering the first space 2, effectively reducing the heat generated in the first space 2 due to natural sunlight. As an example of this embodiment 1, the side wall 9 can also achieve the light-transmitting and blocking effects of the barrier layer 4 by coating the wall surface with a low-emissivity coating, such as a LOW-E coating.

[0041] To improve airflow within the agricultural building unit 100, the side wall 9 has a second vent 10 to form a second vent 10 for introducing natural airflow. The side wall 9 can form the second vent 10 in various ways. For example, as an example of Embodiment 1, the side wall 9 includes a side ventilation member 9a, which can open and close relative to the support member 7. When the side ventilation member 9a is open relative to the support member 7, it forms a second vent 10 for introducing natural airflow. The second vent 10 can cover the entire side wall 9 in the height direction, or it can be arranged only in a portion of the side wall 9 in the height direction, but at least a portion of the second vent 10 is positioned close to the ground, thereby forming an air inlet for natural ventilation. It should be noted that the side ventilation member 9a of Embodiment 1 is part of the side wall 9 of Embodiment 1; therefore, the side ventilation member 9a of Embodiment 1 can also be penetrated by visible light and at least reflects or absorbs one of infrared and ultraviolet light.

[0042] It should be noted that at least some of the second air vents 10 are arranged close to the ground, but it is not required that the second air vents 10 be flush with the ground. Depending on the environmental conditions of the area where this agricultural building unit 100 is located, in some agricultural building units 100, the second air vents 10 can be arranged in an area with a height of 0.5 meters to 1 meter above the ground. Of course, in environments where the ground temperature is not too high, the second air vents 10 in some agricultural building units 100 can be arranged in an area with a height of 0.1 meters to 0.5 meters above the ground.

[0043] In harsh environments such as deserts and sandy lands, in addition to the high temperatures of the atmosphere, long-wave radiation from the ground and pest infestation are also important factors affecting the normal operation of agricultural production. Therefore, in order to create an environment suitable for agricultural production in harsh environments such as deserts and sandy lands, this agricultural building unit 100 also needs to separate the internal space of this agricultural building unit 100 from the external environment. Therefore, this agricultural building unit 100 places the first barrier 11 at the bottom of the first space 2 and the third space 8 to shield the bottom of the first space 2 and the third space 8, so that the bottom of the first space 2 and the bottom of the third space 8 are separated. Separated from the external environment by the ground, the frame 1, top wall 5, side wall 9, support 7, and first barrier 11 work together to separate the top of the first space 2 from the atmospheric environment, the support 7 and side wall 9 work together to separate the third space 8 from the atmospheric environment, and the first barrier 11 separates the bottom of the first space 2 from the atmospheric environment and the bottom of the third space 8 from the atmospheric environment. Thus, the agricultural building unit 100 of this embodiment 1 encloses the first space 2 and the third space 8 in the atmospheric environment, forming an environmental space where the temperature is more suitable for agricultural cultivation than the atmospheric environment.

[0044] As an example of this embodiment 1, the first barrier 11 can be designed to be permeable to water and / or air, such as a water-permeable and air-permeable plastic sheet like weed control cloth. The number of plastic sheets can be determined according to the external environment. This can prevent water accumulation in the first barrier 11 and also prevent pests from the external environment from entering the agricultural building unit 100 through the ground. Of course, the first barrier 11 can also be designed to block water and air, and drainage facilities, such as drainage ditches, can be constructed on the first barrier 11 to prevent water accumulation in the first barrier 11 and also prevent pests from the external environment from entering the agricultural building unit 100 through the ground.

[0045] Through the cooperation of the frame 1, the barrier layer 4, the top wall 5, the side wall 9, the support 7, and the first barrier 11, the agricultural building unit 100 can isolate the first space 2 and the third space 8 from the external environment, reducing the impact of environmental factors such as high temperature and strong winds that are unfavorable to agricultural cultivation on the first space 2 and the third space 8. This allows the first space 2 and the third space 8 to form a space with a temperature more suitable for agricultural cultivation than the atmospheric environment of desert areas. Furthermore, the first barrier 11 isolates the area where the production unit 3 is located and the area between two adjacent production units 3 from the ground of the external environment. This enables the agricultural building unit 100 to construct an agricultural cultivation space with better environmental conditions in harsh environments such as sandy areas and desert areas. Thus, the agricultural building unit 100 can use the first space 2 as the basic environment for agricultural production. By accommodating multiple production units 3 in the first space 2, the agricultural building unit 100 can construct greenhouses, breeding farms, and non-enclosed cultivation fields in harsh environments.

[0046] It should be noted that by configuring the top wall 5 and side wall 9 to allow visible light to pass through and to reflect or absorb at least one of infrared and ultraviolet light, the temperature rise caused by direct infrared and ultraviolet radiation in the first space 2 and the third space 8 can be reduced, thereby reducing the heat accumulation in the first space 2 and the third space 8 due to natural lighting. Furthermore, by separating the first space 2 and the third space 8 from the ground of the external environment through the first barrier 11, the secondary radiation of the external environment ground to the first space 2 and the third space 8 can be effectively suppressed. This comprehensively reduces the heat accumulated in the first space 2 and the third space 8 during natural lighting periods, making this agricultural building unit 100 suitable for hot and arid environments such as sandy land and desert.

[0047] Furthermore, with the cooperation of the top wall 5 and the side wall 9, the first barrier 11 absorbs less solar heat than the ground in the external environment. The temperature of the first barrier 11 is much lower than the surface temperature under direct sunlight. This reduces the long-wave radiation from the first barrier 11 to the first space 2 and the third space 8, thus creating an internal temperature environment in the first space 2 and the third space 8 that is lower than the ambient temperature. In particular, the temperature of the first barrier 11 can be much lower than the ground temperature. For example, in high-temperature areas where the ambient temperature reaches 45-48°C, the temperature of the top wall 5 facing the ground can be reduced to 36-38°C, the temperature of the first space 2 can be reduced to 30-32°C, and the temperature of the first barrier 11 can be reduced to 24-26°C.

[0048] It should be noted that the heat accumulation efficiency of the first space 2 and the third space 8 is different under natural light. The first space 2 is the area where agricultural production activities are carried out in this agricultural building unit 100. Therefore, the first space 2 will accumulate carbon dioxide produced by plants and animals, biothermal energy, and heat emitted by the refrigeration system. In addition, the production unit 3 in the first space 2 will also absorb and accumulate a large amount of heat, which will cause the temperature of the first space 2 to rise. Since the first space 2 is located inside the frame 1, and the third space 8 is located between the support 7 and the frame 1, on the outside of the frame 1, the third space 8 will not be too close to the heat radiation influence area of ​​the first space 2. This will make the heat accumulated in the third space 8 less than the heat accumulated in the first space 2. Since the heat exchange rate of air itself is relatively slow, the temperature of the third space 8 will be lower than the temperature of the first space 2 for a certain period of time when natural ventilation is turned on. This will create a temperature lag zone in the third space 8 relative to the first space 2 during this period of time. That is, the temperature rise rate of the third space 8 during this period of time is less than the temperature rise rate of the first space 2, thus making the third space 8 a low-temperature zone arranged around the first space 2 during this period of time. It should be noted that the thermal radiation influence zone of the first space 2 refers to the effective range of heat radiation from the greenhouse, breeding farm and non-enclosed cultivation field in the first space 2 to the outside.

[0049] It is important to note that under natural sunlight, the heat in the environment mainly comes from direct infrared and ultraviolet radiation, as well as long-wave radiation after the ground absorbs heat. The thermal conductivity of air itself is much lower than that of infrared, ultraviolet, and geothermal radiation. Therefore, with the cooperation of the barrier layer 4, sidewall 9, and first barrier element 11, the temperature of the first space 2 will be lower than the external environment temperature. Thus, when the first space 2 accommodates a greenhouse, a livestock farm, or an open cultivation area, the greenhouse, livestock farm, or open cultivation area uses the air within the first space 2 as the gas exchange medium and is temperature-controlled within the air temperature environment of the first space 2. Compared to the temperature difference caused by traditional greenhouses being directly exposed to the atmosphere, the temperature difference in the first space 2... The temperature difference that needs to be overcome for temperature control in internally constructed greenhouses, breeding farms, and open cultivation areas is smaller. For example, for a greenhouse that needs to control the internal temperature at 24°C, when the external ambient temperature reaches 45-48°C and the temperature of the first space 2 is 30-32°C, the temperature difference that its temperature control components need to overcome is only 6-8°C. Compared with the 21-24°C temperature difference that needs to be overcome in greenhouses in the external environment, this agricultural building unit 100 can effectively reduce the temperature control cost of greenhouses, breeding farms, and open cultivation areas, save the operating energy consumption of greenhouses, breeding farms, and open cultivation areas, and effectively improve the input-output ratio of this agricultural building unit 100 in carrying out agricultural cultivation in marginal lands such as sandy land and deserts.

[0050] It is important to note that when the first vent 6 and the second vent 10 are open, air will enter the third space 8 through the second vent 10 and exit the first space 2 through the first vent 6. This makes the second vent 10 a natural ventilation inlet and the first vent 6 a natural ventilation outlet. This is because the greenhouse, farm, and open cultivation area contained in the first space 2 will accumulate heat. Furthermore, the carbon dioxide and biothermal energy produced by plants and animals, as well as the heat emitted by the refrigeration system, will all cause the temperature of the first space 2 to rise. Since the resistance to vertical airflow is less than the resistance to horizontal airflow, the heated and expanding air in the first space 2 will preferentially flow vertically, continuously escaping from the first vent 6 to the external environment. This will slightly decrease the air pressure in the first space 2, thus causing the first space 2 to continuously draw air from the third space 8. This causes a slight decrease in air pressure in the third space 8, and allows air near the second vent 10 to flow into the agricultural building unit 100. On the other hand, because the ground in the external environment is heated by direct sunlight, the resistance to vertical airflow is less than the resistance to horizontal airflow. The near-ground air near the agricultural building unit 100 will preferentially flow vertically, causing this near-ground air to rise rapidly after being heated, forming a strong updraft. This creates a large-scale low-pressure zone in the near-ground area of ​​the agricultural building unit 100, allowing air at higher altitudes to replenish this near-ground area. However, due to the obstruction of the agricultural building unit 100, air at higher altitudes far away from the agricultural building unit 100 will preferentially replenish this near-ground area over the air above the agricultural building unit 100, thus forming a natural airflow blowing towards the agricultural building unit 100. The natural airflow blowing towards this agricultural building unit 100 enters the third space 8 through the second vent 10, and exchanges heat with the air in the first barrier 11 and the third space 8. This heat-exchanged air flows into the first space 2, and then leaves the agricultural building unit 100 through the first vent 6, thus forming within the agricultural building unit 100... Figure 3 The airflow of natural ventilation from bottom to top, as shown, carries away the cooler air that has settled near the third space 8 and the first barrier 11 within a certain period of time after the natural ventilation is turned on, and diffuses it into the first space 2, thereby rapidly reducing the ambient temperature of the first space 2. In this way, the temperature control cost of the greenhouse, breeding farm and non-enclosed cultivation field built in the first space 2 can be further effectively reduced, saving the operating energy consumption of the greenhouse, breeding farm and non-enclosed cultivation field.

[0051] Considering the high daytime temperatures in hot and arid regions such as deserts and sandy areas, this agricultural building unit 100 can be equipped with more cooling measures. For example, refer to... Figure 1-10As an example of Embodiment 1, the agricultural building unit 100 further includes a second barrier 12, which is located on the outer periphery of the side wall 9 and is provided with a vegetation layer 13. The vegetation layer 13 is adjacent to the second air vent 10 near the ground. In this way, the natural ventilation airflow from the external environment into the agricultural building unit 100 will flow sequentially along the vegetation layer 13, the second air vent 10, and the first air vent 6, forming... Figure 3 The natural ventilation path is shown.

[0052] Understandably, the vegetation layer 13 will be connected to a water source to provide the water needed for its growth, such as through a drip irrigation system. Through transpiration and evaporation of the vegetation water, the area where the vegetation layer 13 is located can form a localized temperature environment lower than the atmospheric environment. By arranging the vegetation layer 13 near the second air vent 10 close to the ground, the vegetation layer 13 can cooperate with the third space 8 to form a dynamically stable localized low-temperature environment similar to a shaded area, allowing the wind passing through the vegetation layer 13 to directly enter the third space 8, avoiding further heat exchange between the wind passing through the vegetation layer 13 and the external ground. Furthermore, the vegetation layer 13 near the second air vent 10 can reduce the wind speed entering the agricultural building unit 100, significantly slowing down the speed at which external air enters the agricultural building unit 100. Moreover, when the airflow from the external environment passes through the vegetation layer 13, it can exchange heat with the vegetation layer 13, thereby pre-cooling the airflow entering the agricultural building unit 100 by the vegetation layer 13, reducing the temperature of the airflow entering the agricultural building unit 100, and preventing the temperature environment of the first space 2 from being affected by the inflow of external hot airflow.

[0053] It should be noted that the agricultural building unit 100 in this embodiment 1, through the cooperation of the first space 2, the third space 8, the first air vent 6, the second air vent 10, the first barrier 11, the second barrier 12, and the vegetation layer 13, forms a dynamically stable temperature environment. Specifically, this temperature environment is achieved by the barrier layer 4 and the side wall 9 working together to reduce direct solar radiation, by the first barrier 11 and the second barrier 12 working together to eliminate erosion from factors unsuitable for cultivation, and by the barrier layer 4, the side wall 9, the first barrier 11, and the second barrier 12 working together to reduce ground heat absorption and secondary radiation in the area where the agricultural building unit 100 is located. Space 2, third space 8, first air vent 6, and second air vent 10 work together to form an area capable of accommodating greenhouses, farms, and non-enclosed cultivation areas. This allows the agricultural building unit 100 to utilize natural winds to create an upward-flowing airflow, diffusing the cooler air near the ground in first space 2 and the cooler air in third space 8 to the entire first space 2. This lowers the ambient temperature of first space 2 and makes the air quality index of first space 2 close to or equal to that of the external environment. As a result, the agricultural building unit 100 can create a local environment suitable for agricultural production in an environment unsuitable for agricultural production, solving the problem of marginal lands being unsuitable for agricultural production due to harsh environments.

[0054] Furthermore, in the agricultural building unit 100 which includes crop cultivation and livestock breeding, the vegetation layer 13 arranged in the second barrier 12 can be used as feed for livestock breeding, and the manure produced by livestock breeding can be used as fertilizer for crop cultivation and planting in the vegetation layer 13. This enables the agricultural building unit 100 to form a closed-loop production and operation mode, reducing the input cost of maintaining agricultural production in the agricultural building unit 100 and increasing the output of agricultural production in the agricultural building unit 100 in harsh environments.

[0055] It should be noted that this agricultural building unit 100 is intended for use in harsh environments and may encounter meteorological disasters such as strong winds and sandstorms. Some agricultural building units 100 can utilize support members 7 to construct windproof and airflow-guiding structures, for example, refer to... Figure 1 and Figure 6One end of the support member 7 is close to the top of the frame 1 and connected to the frame 1. The other end of the support member 7 is connected to the ground. The distance between the support member 7 and the frame 1 decreases from the end of the support member 7 connected to the ground to the end of the support member 7 close to the top of the frame 1. This ensures that the support member 7 can serve as an auxiliary support structure for the frame 1, thereby enhancing the structural strength of the agricultural building unit 100. Furthermore, by setting the support member 7 on the outer periphery of the frame 1 and setting the side wall 9 on the support member 7, when the agricultural building unit 100 encounters meteorological disasters such as strong winds and sandstorms, the side ventilation member 9a can close the second vent 10, making the side wall 9 a guide surface inclined to the ground, guiding the strong winds to the top of the agricultural building unit, reducing the direct impact of strong winds and sandstorms on the agricultural building unit 100, preventing the first space 2 from being directly disturbed by meteorological disasters such as strong winds and sandstorms, and ensuring the ecological safety of agricultural production inside the agricultural building unit 100.

[0056] In some agricultural building units 100, production unit 3 is a livestock farm and an open cultivation area. To provide the soil environment required for the livestock farm and the open cultivation area, a substrate layer 14 can be provided on the first barrier 11, forming the bottom of the second space 3a. For example, external soil or external sand, different from the external environment, can be arranged on the first barrier 11 as the substrate layer 14 of this agricultural building unit 100. This allows the agricultural building unit 100 to cultivate temperate crops using soil cultivation in hot and arid tropical regions such as sandy areas and deserts, greatly reducing the planting costs of cross-regional planting. Of course, in agricultural building units 100 where the first space 2 houses a greenhouse, the substrate layer 14 can also form the greenhouse floor, and the greenhouse can adopt an existing traditional greenhouse structure.

[0057] Considering that the greenhouse located in the first space 2 may require light regulation, in some agricultural building units 100, it is also possible to construct a shed within the first space 2, using louvers as windows for air circulation between the shed and the first space 2. In this type of shed, the louvers can block sunlight from entering; for example, in cases of excessively strong sunlight, the louvers can be adjusted to partially open or completely close, thereby reducing the amount of light entering the shed. Of course, agricultural building units 100 with greenhouses or sheds can also accommodate multi-level equipment within the greenhouses or sheds to fully utilize the planting space inside.

[0058] It is important to note that under strong sunlight, such as during peak hours, the first vent 6 and the second vent 10 of this agricultural building unit 100 will typically remain open to maintain a dynamically stable temperature environment in the first space 2 and the third space 8. Therefore, the first space 2 of this agricultural building unit 100 is not the internal space of a greenhouse or similar structure, but rather the external space that accommodates such structures. For example, the first space 2 can simultaneously accommodate several greenhouses and several farms, such as glass greenhouses, double-layer greenhouses, and chicken farms, forming a local ecosystem with a temperature different from the external atmospheric environment. By arranging multiple production units 3 within the first space 2 and separating the external environment through the top wall 5, side walls 9, and the first barrier 11, this agricultural building unit 100 can construct a farm environment suitable for agricultural cultivation within the frame 1. In this way, the production units 3 arranged within the first space 2 can use the temperature environment of the first space 2 as the basis for their own temperature management, achieving low-energy consumption management. This avoids the production units 3 within the first space 2 using the external atmospheric environment as the basis for their own temperature management, which would significantly increase energy consumption for temperature management under the influence of high external temperatures. Of course, the first space 2 can also be configured with other supporting units to assist in agricultural cultivation, such as a soil preparation center, to provide suitable soil for agricultural cultivation, so that this agricultural building unit 100 can carry out agricultural production activities in harsh environments.

[0059] Understandably, different environments place different demands on the protective performance of the agricultural building unit 100. For example, in some environments, this agricultural building unit 100 requires better wind deflection capacity to resist external windflow. (Reference) Figure 2-8 , Figure 2 The black arrow in the middle indicates the direction of the airflow. Figure 8 The white arrow in the middle indicates the direction of sunlight. Figure 8 The arrow in the middle line indicates the direction of infrared light reflection. The side wall 9 may include multiple side ventilation elements 9a and multiple side light-transmitting elements 9b. The multiple side light-transmitting elements 9b are connected and fixed to the support 7, and at least some of the side light-transmitting elements 9b are arranged alternately with some of the side ventilation elements 9a. By fixing the side light-transmitting elements 9b to the support 7, the side wall 9 can have higher structural strength, thereby enabling the agricultural building unit 100 to withstand greater airflow from the external environment. It should be noted that the side light-transmitting elements 9b are also part of the side wall 9, so visible light can also pass through them, and they reflect or absorb at least one of infrared and ultraviolet light. Of course, the side wall 9 of some agricultural building units 100 may also consist only of side light-transmitting elements 9b. In this type of side wall 9, the second vent 10 can be arranged open and insulated with heat insulation measures such as insulation blankets. When the temperature of the external environment drops to a level unsuitable for crop growth, the second vent 10 can be closed.

[0060] As an example of Embodiment 1, the side-transmitting element 9b can also be a polycarbonate sheet. To avoid the side-transmitting element 9b affecting the temperature environment of the first space 2 and the third space 8, the polycarbonate sheet used in the side-transmitting element 9b is preferably constructed to allow visible light to pass through and to reflect or absorb at least one of infrared and ultraviolet light, for example, by coating the polycarbonate sheet with a LOW-E coating. Of course, considering the large temperature difference between day and night in environments such as deserts and sandy areas, the side-transmitting element 9b can also be made of heat-insulating glass to reduce the impact of the external environment on the temperature environment of the first space 2.

[0061] The top wall 5 has various structural designs to adapt to different environments. (Reference) Figure 6 As an example of Embodiment 1, the top wall 5 of the agricultural building unit 100 includes a top ventilation component 5a. The top ventilation component 5a can open and close relative to the frame 1 to form a first air vent 6. The top ventilation component 5a is permeable to visible light and can at least reflect or absorb one of infrared and ultraviolet light to form a barrier layer 4. The opening and closing of the top ventilation component 5a can be controlled by means of a motor or similar means. By opening and closing the top ventilation component 5a relative to the frame 1, the degree of opening of the first air vent 6 relative to the frame 1 can be adjusted, allowing the agricultural building unit 100 to adjust the temperature environment of the first space 2. Furthermore, by enabling the top ventilation component 5a to reflect or absorb one of infrared and ultraviolet light, the heat accumulated in the first space 2 due to natural sunlight can be reduced, thus lowering the heat accumulation in the first space 2 and reducing the air temperature used for circulation in the second space 3a. In this type of agricultural building unit 100, the greenhouse housed in the first space 2 can be a film greenhouse. Of course, depending on the needs of the crops grown in the greenhouse and the external environment, the greenhouse housed in the first space 2 can also be a glass greenhouse, and the glass is constructed to allow visible light to pass through and to reflect or absorb at least one of infrared and ultraviolet light.

[0062] It should be noted that the top ventilation component 5a can be coated with a low-emissivity coating, such as a LOW-E coating, so that the barrier layer 4 can reflect far-infrared light (wavelength > 2500 nm), reflect near-infrared light (wavelength in the range of 780 to 2500 nm), and absorb ultraviolet light (wavelength in the range of 100 to 380 nm), while allowing visible light (wavelength in the range of 380 to 780 nm) to enter the first space 2.

[0063] In some agricultural building units 100, refer to Figure 7-8The top wall 5 may also include multiple top ventilation elements 5a and multiple top light-transmitting elements 5b to enhance the strength of the top wall 5. These top light-transmitting elements 5b are fixed above the first space 2, and are able to allow visible light to pass through while reflecting or absorbing at least one of infrared and ultraviolet light to form a barrier layer 4. The top light-transmitting elements 5b are arranged alternately with the top ventilation elements 5a, thus saving the number of top ventilation elements 5a required and reducing the assembly cost of this agricultural building unit 100. Furthermore, by adjusting the distribution of the top ventilation elements 5a according to whether the first space 2 contains a greenhouse, a farm, or an enclosed cultivation area, it can be ensured that the first air vents 6 formed by these top ventilation elements 5a meet the ventilation requirements of the first space 2. The blocking effect of the top light-transmitting elements 5b on sunlight is the same as that of the top ventilation elements 5a, and will not be described further here. Of course, the top wall 5 can also be composed of multiple top light-transmitting elements 5b. In this type of top wall 5, the first air vent 6 can also be arranged in an open manner and heat insulation measures such as heat insulation blankets can be adopted so that the first air vent 6 can be closed when the temperature of the external environment drops to a level unsuitable for crop growth.

[0064] It should be noted that in the agricultural building unit 100 where the top wall 5 is constructed using a top light-transmitting element 5b, the first air vent 6 may be arranged openly. In this type of agricultural building unit 100, a top ventilation element 5a can be considered at the first air vent 6, or other structures can be considered. For example, as an example of this embodiment 1, refer to... Figure 9 In this type of agricultural building unit 100, the top wall 5 may also include multiple translucent roof films 5d, which are allowed to be transmitted by sunlight and are movably connected to the first vent 6 to open and close the first vent 6. The opening degree of the first vent 6 can be controlled by a motor winding mechanism for the translucent roof films 5d. Considering that some agricultural building units 100 may require insulation during sunset, the translucent roof films 5d can be made of insulating film. Compared to the cost of the top ventilation component 5a, the cost of the translucent roof films 5d is lower, which helps to reduce the overall cost of this agricultural building unit 100.

[0065] Based on the lighting requirements of this agricultural building unit 100 and the external temperature environment, the roof wall 5 selectively employs a combination of roof ventilation components 5a, roof light-transmitting components 5b, and roof light-transmitting membrane 5d. For example, in some agricultural building units 100, the roof wall 5 may be configured with both roof light-transmitting components 5b and roof light-transmitting membrane 5d. Of course, since the roof light-transmitting membrane 5d does not filter infrared and ultraviolet light, in hot and arid regions such as sandy areas and deserts, the roof wall 5 may also consider using a structure combining roof ventilation components 5a, roof light-transmitting components 5b, and roof light-transmitting membrane 5d, which can reduce the amount of infrared and ultraviolet light entering the first space 2.

[0066] In an agricultural building unit 100 with side ventilation components 9a configured on the side wall 9, the side ventilation components 9a at least constitute part of the outer wall of the agricultural building unit 100 and are exposed to natural light. To reduce heat conduction between the external environment and the first space 2 and the third space 8, and to maintain a locally low-temperature environment in the first space 2 and the third space 8, the side ventilation components 9a may be designed with thermal insulation. (Reference) Figure 10 As an example of this embodiment 1, the side ventilation component 9a includes a first end side 9a1 and a second end side 9a2. The first end side 9a1 and the second end side 9a2 surround each other to form a cavity 9a3. Furthermore, the first end side 9a1 has a first segment 9a10 and a second segment 9a11 that are connected to each other, and the first segment 9a10 and the second segment 9a11 gradually move towards the second end side 9a2 from their connection point. The first segment 9a10 and the second segment 9a11 can be planar structures, which is beneficial for the side ventilation component 9a to cooperate with the adjacent side light transmission component 9b or another adjacent side ventilation component 9a to form an airflow guiding surface when the two adjacent side ventilation components 9a are closed, thereby guiding the airflow to flow along the side wall 9. Furthermore, considering that some agricultural building units 100 need to resist strong winds through the side ventilation component 9a, in some side ventilation components 9a, the cavity 9a3 can be provided with a reinforcing rib 9a4. The reinforcing rib 9a4 is connected and fixed to the second end side 9a2 and the first end side 9a1, thereby enhancing the structural strength of the side ventilation component 9a.

[0067] Through the cooperation of the second end 9a2, the first end 9a1, and the cavity 9a3, the side ventilation member 9a can slow down the intrusion of heat from the external environment into the third space 8, reducing heat conduction between the third space 8 and the external environment. Furthermore, when two adjacent side ventilation members 9a are open in the height direction, a funnel-shaped opening can be formed between the first section 9a10 and the second section 9a11 of the two adjacent side ventilation members 9a, thereby creating a narrow tube effect between the two adjacent side ventilation members 9a, accelerating the flow of external air into the third space 8.

[0068] Of course, the top ventilation component 5a can also adopt the same structure as the side ventilation component 9a, that is, the top ventilation component 5a includes a third end side and a fourth end side, which enclose each other to form a cavity. Furthermore, the third end side has a third segment and a fourth segment that are connected to each other. The third segment and the fourth segment gradually move towards the fourth end side from the connection point between the two. The third end side has the same structure as the first end side 9a1, the fourth end side has the same structure as the second end side 9a2, the third segment has the same structure as the first segment 9a10, and the fourth segment has the same structure as the second segment 9a11. Therefore, the top ventilation component 5a can also achieve the blocking and drainage effect of the side ventilation component 9a by adopting this structure. No further illustrations are provided here.

[0069] Considering the abundant sunlight in desert and sandy areas, where air temperatures can reach over 50°C under sunlight, the agricultural building unit 100 may require the addition of a barrier structure to the exterior of its roof wall 5. Furthermore, given the energy consumption required for agricultural production in greenhouses, livestock farms, and open cultivation areas, the agricultural building unit 100 can be equipped with a photovoltaic module 15. The photovoltaic module 15 provides shading for the roof wall 5 and supplies green energy for agricultural production.

[0070] refer to Figure 1 The agricultural building unit 100 of this embodiment 1 includes a photovoltaic group 15, which is located above the frame 1 and connected to the top of the frame 1. The photovoltaic group 15 includes at least a plurality of photovoltaic panels 15a, which can be connected to electrical equipment in the first space 2. In this way, solar energy can be recovered through the photovoltaic panels 15a, which can at least provide some of the electrical energy required for agricultural production in this agricultural building unit 100 and provide appropriate shading for the top wall 5.

[0071] It should be noted that the spacing between photovoltaic panels 15a in this agricultural building unit 100 is configured based on the light intensity inside the first space 2, rather than based on the solar energy recovery of photovoltaic panels 15a. Therefore, the spacing between photovoltaic panels 15a in this agricultural building unit 100 may be equal to or greater than the commonly used spacing between other existing photovoltaic panels 15a.

[0072] To facilitate the assembly of the top wall 5 and reduce its wind resistance, in some agricultural building units 100, the top of the frame 1 can be configured as a flat structural layer, to which the top wall 5 is connected. For example, as an example of this embodiment 1, refer to... Figure 1 The top of frame 1 is a flat structure, and the top wall 5 is arranged along the extension direction of the flat structure, thereby separating the top of the first space 2 from the external environment. Of course, there are many ways to realize the flat structure of frame 1. For example, as an example of this embodiment 1, frame 1 includes multiple columns 1a and multiple top beams 1b; multiple columns 1a are erected; multiple top beams 1b are connected to the top of the columns 1a to form a flat structure.

[0073] It should be noted that the flat structure of frame 1 is a horizontally arranged frame structure, ensuring that the top of frame 1 is at the same horizontal level. For example, multiple top beams 1b are arranged horizontally and interconnected to form a frame structure similar to a window frame, thus opening the top of frame 1. Furthermore, the top of frame 1 forms a horizontally arranged frame structure, i.e., a flat structure. The top wall 5, installed within this flat structure, also forms a horizontally arranged wall, reducing wind resistance.

[0074] Example 2 The difference between this embodiment 2 and embodiment 1 is that, in the agricultural building unit 100 of this embodiment 2, the barrier layer 4 is disposed below the top wall 5 and arranged within the first space 2, that is, the top wall 5 does not constitute the barrier layer 4. In this type of agricultural building unit 100, the top wall 5 is constructed to allow sunlight to pass through.

[0075] refer to Figure 11-12 The production unit 3 includes a partition 19 located within the first space 2. This partition 19 is permeable to visible light and reflects or absorbs at least one of infrared and ultraviolet light to form a barrier layer 4. It should be noted that the partition 19 is spaced apart from the first barrier 11 in the height direction, and the partition 19 forms the top of the second space 3a; alternatively, the partition 19 is positioned above the second space 3a, with a separate plate disposed on the top of the second space 3a.

[0076] refer to Figure 11-12 As an example of arranging a barrier layer 4 within the first space 2, in a portion of the agricultural building unit 100, a polycarbonate panel serving as a separator 19 is provided within the first space 2. The polycarbonate panel is spaced apart from the roof wall 5 and located away from the heat radiation affected area of ​​the roof wall 5, to prevent the heat generated by the roof wall 5 under sunlight from increasing the greenhouse's energy consumption. The polycarbonate panel cooperates with the first barrier 11 to form a second space 3a within the first space 2. The second space 3a is separated from the first space 2. Furthermore, the polycarbonate panel is constructed to allow visible light to pass through and to reflect or absorb at least one of infrared and ultraviolet light to form the barrier layer 4. It should be noted that the heat radiation affected area of ​​the roof wall 5 refers to the effective range within which the roof wall 5 heats up due to sunlight and radiates heat to the outside.

[0077] The aforementioned polycarbonate panels can achieve light transmission and filter infrared and ultraviolet light by coating the wall surface with a low-emissivity coating, such as a LOW-E coating. Using polycarbonate panels, a closed planting area can be constructed within the first space 2. Furthermore, the multiple barriers and shading effects formed by the partition 19 and the top wall 5 can effectively reduce the cooling energy consumption of the second space 3a. To maintain the temperature inside the greenhouse, the second space 3a can also be equipped with temperature control components, such as an air conditioning system based on an air-source heat pump.

[0078] Of course, in some agricultural building units 100, the polycarbonate sheet serving as the top wall of the second space 3a can also be made to allow only sunlight to pass through. In this type of agricultural building unit 100, a light-transmitting panel coated with a low-emissivity coating is arranged between the polycarbonate sheet and the top wall 5, which also allows for the arrangement of a barrier layer 4 within the first space 2.

[0079] It should be noted that in the agricultural building unit 100 of this embodiment 2, the top wall 5 can still be formed by the combination of the top ventilation component 5a and / or the top light-transmitting component 5b and / or the top light-transmitting film 5d. Of course, in the agricultural building unit 100 of this embodiment 2, the top ventilation component 5a and the top light-transmitting component 5b do not need to be coated with a low-emissivity coating so that sunlight can pass through the top ventilation component 5a and the top light-transmitting component 5b without reflecting or absorbing infrared and ultraviolet light.

[0080] It should be noted that in some agricultural building units 100, the partition 19 of this embodiment 2 can be used in conjunction with the top wall 5 of embodiment 1. For example, in this type of agricultural building unit, part of the top wall 5 is configured with a low-emissivity coating to form the top wall 5 of embodiment 1, constituting part of the barrier layer 4. Furthermore, in this type of agricultural building unit 100, the partition 19 is configured in the first space 2 to form the remaining part of the barrier layer 4.

[0081] The other structures of this embodiment 2 are the same as those of embodiment 1, and will not be described again here.

[0082] Example 3 The difference between Example 3 and Example 1 is that, referring to... Figure 13 In the agricultural building unit 100 of this embodiment, the photovoltaic panels 15a are arranged at an angle, that is, the photovoltaic panels 15a are inclined to the top of the frame 1 and are connected to the top of the frame 1 through the mounting frame. Multiple photovoltaic panels 15a are arranged in a row, and two adjacent photovoltaic panels 15a have a first spacing channel 16 and a first light transmission channel 17 that are interconnected.

[0083] It should be noted that the first spacing channel 16 refers to the spacing between two adjacent photovoltaic panels 15a in the arrangement direction. When the photovoltaic panels 15a are installed at an angle, the length of the first spacing channel 16 is typically the distance between two adjacent photovoltaic panels 15a during the period from 9:00 to 15:00 on the winter solstice, ensuring that neither panel blocks the other's sunlight. Existing photovoltaic panels 15a are usually arranged with the first spacing channel 16 as the interval to maximize the illuminated area.

[0084] In the agricultural building unit 100 of this embodiment 3, the light intensity of the first space 2 may not meet the light requirements of agricultural production due to the shading effect of the photovoltaic panels 15a. Therefore, in addition to the first spacing channel 16, the agricultural building unit 100 also provides a first light-transmitting channel 17 between two adjacent photovoltaic panels 15a, allowing sunlight to enter the first space 2 through the first light-transmitting channel 17. This ensures that the light-transmitting area between two adjacent photovoltaic panels 15a is sufficient to meet the light intensity requirements of the first space 2 and provides shading for the top wall 5. Of course, in some agricultural building units 100, at least some first vents 6 can also be arranged between two adjacent rows of photovoltaic modules 15, allowing light to pass through and thus increasing the light intensity of the first space 2. The number of first vents 6 arranged between two adjacent rows of photovoltaic modules 15 can be adjusted according to the light intensity required by the first space 2 and the sunlight conditions of the external environment.

[0085] It should be noted that the photovoltaic panel 15a generates a certain amount of heat during operation. Since the photovoltaic panel 15a is located above the frame 1 and connected to the top of the frame 1, it may be close to the first air vent 6 located on the top wall 5, affecting the air exhaust from the first space 2. Therefore, in some agricultural building units 100, the photovoltaic panel 15a can be placed in a higher altitude area, for example, referring to... Figure 13 The photovoltaic panel 15a is spaced apart from the top wall 5 on the side facing the frame 1 to form a ventilation channel 18. The ventilation channel 18 is connected to the first spaced channel 16 and the first light-transmitting channel 17, and the ventilation channel 18 is located below the heat radiation affected area of ​​the photovoltaic panel 15a.

[0086] It should be noted that the heat radiation affected zone of the photovoltaic panel 15a refers to the effective range of heat radiated to the outside by the heat source generated by the photovoltaic panel 15a during normal operation. By setting the side of the photovoltaic panel 15a close to the frame 1 at an interval from the top wall 5, and placing the ventilation channel 18 below the heat radiation affected zone of the photovoltaic panel 15a, the photovoltaic panel 15a can be kept sufficiently away from the top wall 5, preventing the air flowing out of the first air outlet 6 from becoming turbulent due to the heat radiation affected zone of the photovoltaic panel 15a, and also allowing the photovoltaic panel 15a to provide shading and blocking for the top wall 5.

[0087] The other structures of this embodiment 3 are the same as those of embodiment 1, and will not be described again here.

[0088] Example 4 The difference between Example 4 and Example 2 is that, referring to... Figure 14-15In this embodiment 4, the top wall 5 of the agricultural building unit 100 is connected to the top of the frame 1. The top wall 5 includes a guide section 5c that is inclined to the ground. The guide section 5c has a first end 5c1 and a second end 5c2 that are arranged opposite to each other. The first end 5c1 is close to the side of the frame 1 facing the first space 2, and the second end 5c2 extends upward toward the frame 1, so that the guide section 5c and the frame 1 form a guide space 20 above the first space 2. The second end 5c2 and the frame 1 form a first air vent 6, which is located on the side of the guide section 5c facing the first space 2.

[0089] It is understood that the airflow guide 5c can be formed by either the top light-transmitting element 5b or the top light-transmitting film 5d, or by the cooperation of the top light-transmitting element 5b and the top light-transmitting film 5d. By arranging the airflow guide 5c at an angle to the ground, a windproof and airflow guiding structure can be formed above the frame 1. For example, in an agricultural building unit 100 oriented to the north, wind blowing from the north at a height close to the top of the frame 1 will flow upwards under the guidance of the airflow guide 5c, away from the first air vent 6, thereby reducing the possibility of external ambient air entering the first space 2 through the first air vent 6. In this way, the first air vent 6 can be arranged openly, eliminating the need to arrange the top ventilation element 5a at the first air vent 6, thus reducing the arrangement and control costs of this agricultural building unit 100.

[0090] Secondly, by means of the guide section 5c being arranged at an angle to the ground, a guide space 20 is formed between the guide section 5c located on the top outer side of the frame 1 and the frame 1. This guide space 20 is located above the first space 2 and can receive the hot air rising from the first space 2 and guide this hot air to the first air outlet 6.

[0091] It should be noted that after air is heated, its vertical movement takes precedence over its horizontal movement. Therefore, in the absence of other factors, heated air usually flows upward. As a result, the guide section 5c connected to the top of the frame 1 can receive the hot air rising from the first space 2 and guide the hot air from its vertical flow to a horizontal flow, so that the hot air can flow smoothly to the first air outlet 6, avoiding the accumulation of hot air in the first space 2 and affecting the dynamic and stable temperature environment of the first space 2 and the third space 8.

[0092] refer to Figure 14In some agricultural building units 100, there are multiple airflow guides 5c. These multiple airflow guides 5c are arranged sequentially. The second end 5c2 of any airflow guide 5c extends above the first end 5c1 of the adjacent airflow guide 5c, and a connecting part (not shown in the figure) connects the second end 5c2 of any airflow guide 5c to the first end 5c1 of the adjacent airflow guide 5c. The connecting part is vertically arranged and has a first air vent 6. In this way, the multiple airflow guides 5c cooperate to form a windproof structure. For example, in an agricultural building unit 100 where the airflow guides 5c face north, wind from the north, near the top of the frame 1, will be guided by the first airflow guide 5c on the north side, flowing upwards and away from the first air vent 6, preventing external airflow from affecting the airflow out of the first space 2. Even if some airflow bypasses the first guide section 5c on the north side and flows into the second guide section 5c on the north side, the second guide section 5c on the north side will still guide this part of the airflow to flow upward, so that these airflows are away from the first vent 6. In this way, in the agricultural building unit 100 with the guide section 5c facing the north side, only the southernmost first vent 6 has the possibility of airflow entering in the opposite direction, which greatly reduces the impact of the external environment on the first space 2 and the third space 8.

[0093] Some agricultural building units 100 may not require side ventilation components 9a on every side. In this type of agricultural building unit 100, it is possible to omit the side ventilation component 9a on the side facing away from the sun. For example, the agricultural building unit 100 has at least a sun-facing side and a shady side arranged opposite each other, and the side ventilation component 9a is arranged on at least the other sides besides the shady side. The sun-facing side is the main lighting side of this agricultural building unit 100, that is, the side that receives direct sunlight during the peak sunshine period (10:30 to 15:00), and the opposite side is the shady side. Taking the Northern Hemisphere as an example, the sun-facing side is usually the south side or a region close to the south, and the shady side is the north side or a region close to the north.

[0094] The other structures in this embodiment 4 are the same as those in embodiment 2, and will not be described again here.

[0095] Example 5 The difference between Example 5 and Example 4 is that, referring to... Figure 16-18 In this embodiment 5, the first air vent 6 of the agricultural building unit 100 is arranged at an angle to the ground, and the top wall 5 includes a plurality of top light-transmitting films 5d, which can be passed through by sunlight and are movably connected to the first air vent 6, so that the top light-transmitting films 5d can be opened and closed along the arrangement direction of the first air vent 6, thereby opening and closing the first air vent 6 and forming a guide surface 21.

[0096] By arranging the first air vent 6 at an angle to the ground and placing a top-transparent membrane 5d at the first air vent 6, the top-transparent membrane 5d enables the top of the frame 1 to form a guiding structure. For example, when the first air vent 6 is partially open, the top-transparent membrane 5d will partially cover the first air vent 6. At this time, the portion of the top-transparent membrane 5d covering the first air vent 6 is angled to the ground and can guide the hot air rising from the first space 2 to the opening of the first air vent 6, allowing this hot air to flow out from the first air vent 6. Compared to forming the first air vent 6 through the top ventilation component 5a or keeping the first air vent 6 open, using the top-transparent membrane 5d movably connected to the first air vent 6 can reduce the configuration cost of the first air vent 6 and provide operable opening and closing control for the first air vent 6.

[0097] It is understandable that the frame 1 itself has a certain thickness. Therefore, even if the top of the frame 1 adopts a flat structure, the first air outlet 6 can still be arranged at an angle by utilizing the thickness of the frame 1.

[0098] refer to Figure 16-18 In the agricultural building unit 100 of this embodiment 5, other locations of the top wall 5 also include multiple top-transparent films 5d. These films 5d allow sunlight to pass through and are fixed above the first space 2. Thus, in the agricultural building unit 100 of this embodiment 5, the entire top wall 5 is constructed using the top-transparent films 5d. It should be noted that by using the top-transparent films 5d as the top wall 5, fixing them above the first space 2, and covering the first vent 6 with the top-transparent films 5d, this agricultural building unit 100 allows infrared and ultraviolet light to enter the interior of the first space 2 during sunlight hours, increasing the temperature reserve of the first space 2. Therefore, the agricultural building unit 100 of this embodiment 5 is suitable for cold regions and can provide a good cold-resistant environment for the agricultural building unit 100.

[0099] Considering the low temperatures in frigid regions, this agricultural building unit 100 can be equipped with more insulation measures for applications in frigid areas, i.e., regions where the weekly average ambient temperature is below 0°C. (Reference) Figure 18 As an example of this embodiment 5, under the second ambient temperature condition, i.e. when the weekly average ambient temperature is below 0°C, the sidewall 9 is configured to be able to be penetrated by sunlight, so that infrared light and ultraviolet light can enter the third space 8 and the first space 2 through the sidewall 9 during the sunshine period, thereby increasing the temperature reserve of the third space 8 and the first space 2.

[0100] Similar to the top wall 5, the side wall 9 also has various structural designs to adapt to different environments. For example, the side wall 9 includes a side ventilation member 9a, which can open and close relative to the support member 7, and when the side ventilation member 9a is open relative to the support member 7, it forms a second vent 10 for introducing natural airflow. It should be noted that the side ventilation member 9a in this embodiment 5 is part of the side wall 9 in this embodiment 5, so the side ventilation member 9a in this embodiment 5 can also be penetrated by sunlight. Alternatively, the side wall 9 may include multiple side ventilation members 9a and multiple side light-transmitting members 9b, the multiple side light-transmitting members 9b being connected and fixed to the support member 7, and at least some of the side light-transmitting members 9b are arranged at intervals from some of the side ventilation members 9a. It should be noted that the side light-transmitting members 9b in this embodiment 5 are also part of the side wall 9 in this embodiment 5, so the side light-transmitting members 9b in this embodiment 5 can also be penetrated by sunlight. As an example of this embodiment 5, the side light-transmitting members 9b can be made of panels with high structural strength, such as polycarbonate sheets.

[0101] In areas where wind resistance requirements are not high, the sidewall 9 can also be assembled using a thin film. For example, refer to... Figure 18 As an example of this embodiment 5, the sidewall 9 includes a plurality of side-transparent films 9c, which are able to be penetrated by sunlight and are connected and fixed to the support member 7.

[0102] Of course, considering the need for opening and closing the second vent, the side wall 9 of this type of agricultural building unit 100 can also be covered with a film at the second vent 10, for example, referring to... Figure 18 As an example of this embodiment 5, the sidewall 9 also includes a plurality of side-transparent films 9c, which are allowed to be penetrated by sunlight. These films are movably connected to the second vent 10 to open and close the vent 10. Compared to the side ventilation component 9a and the side-transparent component 9b, the side-transparent films 9c reduce sunlight scattering, increase the temperature reserve of the third space 8 and the first space 2, and by opening the side-transparent films 9c connected to the second vent 10, the agricultural building unit 100 of this embodiment 5 can achieve the same ventilation effect as the agricultural building unit 100 of embodiment 4.

[0103] The other structures of this embodiment 5 are the same as those of embodiment 4, and will not be described again here.

[0104] In summary, the agricultural building unit 100 provided in this application, through the cooperation of the frame 1, support member 7, top wall 5, side wall 9 and first barrier member 11, with the top wall 5 and frame 1 separating the top of the first space 2 from the atmospheric environment, the side wall 9 and support member 7 separating the perimeter of the first space 2 from the atmospheric environment, and the first barrier member 11 separating the bottom of the first space 2 from the atmospheric environment, thereby encloses the first space 2 and the third space 8 in the atmospheric environment, forming an environmental space with a temperature more suitable for agricultural cultivation than the atmospheric environment. In this way, the agricultural building unit 100 of this application can construct an agricultural cultivation space with better environmental conditions in harsh environments such as sandy areas, desert areas, and frigid areas. Thus, the agricultural building unit 100 of this application can use the first space 2 as the basic environment for agricultural production and construct greenhouses, breeding farms and non-enclosed cultivation fields in harsh environments.

[0105] Secondly, this agricultural building unit 100, by configuring the top wall 5 and side walls 9 to allow visible light to pass through and to reflect or absorb at least one of infrared and ultraviolet light, protects the first space 2 and the third space 8 from direct infrared and ultraviolet radiation, reducing heat accumulation in the first space 2 and the third space 8 due to natural lighting. Furthermore, the first barrier 11 separates the first space 2 and the third space 8 from the ground of the external environment, effectively suppressing secondary radiation from the ground to the first space 2 and the third space 8. Moreover, the cooperation of the top wall 5 and the side walls 9... In this agricultural building unit 100, under direct sunlight, the first barrier 11 absorbs less solar heat than the ground in the external environment, and the temperature of the first barrier 11 will be much lower than the surface temperature under direct sunlight. This reduces the long-wave radiation of the first barrier 11 to the first space 2 and the third space 8, thereby making the temperature of the first space 2 and the third space 8 lower than the temperature of the atmospheric environment. As a result, the temperature control cost of the greenhouse, breeding farm and non-enclosed cultivation field built in the first space 2 can be effectively reduced, saving the operating energy consumption of the greenhouse, breeding farm and non-enclosed cultivation field.

[0106] Secondly, the agricultural building unit 100 arranges a vegetation layer 13 on the outer periphery of the side wall 9 through the second barrier 12. Under the transpiration of the vegetation layer 13 and the evaporation of the vegetation water, the area where the vegetation layer 13 is located can form a local temperature environment with a temperature lower than the ground temperature of the atmospheric environment. Combined with the temperature environment of the third space 8, the airflow of the atmospheric environment can enter the agricultural building unit 100 from the second air vent 10 and leave the agricultural building unit 100 through the first air vent 6, thereby forming a natural ventilation airflow from bottom to top in the first space 2. During a certain period of time when the natural ventilation is turned on, the lower temperature air that has settled in the third space 8 and near the first barrier 11 is diffused into the first space 2, thereby quickly reducing the ambient temperature of the first space 2. In this way, the temperature control cost of the greenhouse, breeding farm and non-enclosed cultivation field built in the first space 2 can be effectively reduced, saving the operating energy consumption of the greenhouse, breeding farm and non-enclosed cultivation field.

[0107] Secondly, the agricultural building unit 100, through the vegetation layer 13 adjacent to the second air vent 10 and in conjunction with the third space 8, can form a dynamically stable local low-temperature environment similar to a shaded area. The vegetation layer 13 can reduce the wind speed entering the agricultural building unit 100, significantly slowing down the intrusion of hot air from the external environment into the agricultural building unit 100. Moreover, when the airflow from the external environment passes through the vegetation layer 13, it can exchange heat with the vegetation layer 13, thereby pre-cooling the airflow entering the agricultural building unit 100 by the vegetation layer 13, reducing the temperature of the airflow entering the agricultural building unit 100, and preventing the inflow of external airflow from excessively affecting the temperature environment of the first space 2.

[0108] Secondly, by setting support members 7 on the outer periphery of the frame 1 and setting side walls 9 on the support members 7, when the agricultural building unit 100 encounters meteorological disasters such as strong winds and sandstorms, the side ventilation members 9a can be closed, making the side walls 9 become a guide surface 21 inclined to the ground, so that the first space 2 is protected from meteorological disasters such as strong winds and sandstorms, and the ecological safety of agricultural production inside the agricultural building unit 100 is ensured.

[0109] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
