Description

Technical Field

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

[0002] Agricultural activities carried out in harsh environments such as arid deserts, high-altitude permafrost, and saline-alkali mudflats generally face the constraints of energy consumption and ecological fragility. For example, agricultural activities carried out in desert areas are severely restricted by environmental factors such as high temperature and drought, and the efficiency of animal husbandry will be severely restricted. For example, in a high temperature environment, the feed intake of fattening pigs will drop by 20% to 40%, and the sow conception rate will decrease and the risk of stillbirth will increase. Secondly, agricultural cultivation in a high temperature environment usually relies on greenhouse regulation. However, due to the large temperature difference between day and night in desert areas, temperature regulation in greenhouses will generate huge energy consumption, resulting in an imbalance in the ratio of energy input to crop output, which is not suitable for promotion and popularization.

[0036] Compared with the prior art, the agricultural building unit implemented by the present application has the following beneficial effects:

[0037] The agricultural building unit of the present application separates the top of the first space and the atmospheric environment by the cooperation of the top wall body and the frame, separates the third space and the atmospheric environment by the cooperation of the side wall body and the support, and separates the bottom of the first space and the third space and the atmospheric environment by the first barrier, so as to enclose the first space and the third space in the atmospheric environment, form an environment space with a temperature more suitable for agricultural cultivation than the atmospheric environment, and thus the agricultural building unit of the present application can construct an agricultural cultivation space with more optimal environmental conditions in a harsh environment such as a sandy area, a desert area, and a severe cold area, so that the agricultural building unit of the present application can use the first space as a basic environment for agricultural production and construct a greenhouse, a breeding farm, and an open cultivation field in a harsh environment.

[0038] Secondly, the agricultural building unit of the present application configures the top wall body and the side wall body to be capable of being penetrated by visible light and at least one of reflecting or absorbing infrared light and ultraviolet light, so as to prevent the first space and the third space from being directly irradiated by infrared light and ultraviolet light, reduce the heat accumulation of the first space and the third space caused by natural lighting, and separate the first space and the third space from the ground of the external environment by the first barrier, effectively inhibit the secondary radiation of the ground of the external environment to the first space and the third space, and in the cooperation of the top wall body and the side wall body, the light absorption heat of the first barrier is lower than that of the ground of the external environment in the case of direct sunlight, the temperature of the first barrier will be much lower than the ground temperature of direct sunlight, so as to reduce the long-wave radiation of the first barrier to the first space and the third space, so that the temperature of the first space and the third space is lower than that of the atmospheric environment, so that the temperature control cost of the greenhouse, the breeding farm, and the open cultivation field constructed in the first space can be effectively reduced, and the operation energy consumption of the greenhouse, the breeding farm, and the open cultivation field can be saved.

[0039] Secondly, the agricultural building unit is provided with a vegetation layer arranged on the outer circumferential side of the side wall body through the second partition, and under the transpiration of the vegetation layer and the evaporation of water for the vegetation, a local air temperature environment with a temperature lower than the ground temperature of the atmospheric environment can be formed in the region where the vegetation layer is located, in combination with the air temperature environment of the third space, the air flow of the atmospheric environment can enter the agricultural building unit from the second air outlet and leave the agricultural building unit through the first air outlet, so as to form a natural ventilation air flow from bottom to top in the first space, and in a certain time of opening the natural ventilation, the air with a lower temperature settled in the third space near the first partition can be diffused to the first space, so as to quickly reduce the environmental temperature of the first space, in this way, the temperature control cost of the greenhouse, the breeding field and the non-closed cultivation field constructed in the first space can be effectively reduced, and the operation energy consumption of the greenhouse, the breeding field and the non-closed cultivation field can be saved.

[0040] Secondly, the vegetation layer adjacent to the second air outlet cooperates with the third space, so that a local low-temperature environment similar to a tree shade area and dynamic stable can be formed. The vegetation layer can reduce the wind speed entering the agricultural building unit, so that the speed of the hot air in the external environment invading the agricultural building unit is greatly slowed down, and when the air flow in the external environment passes through the vegetation layer, heat exchange can occur between the air flow and the vegetation layer, so that the air flow entering the agricultural building unit is pre-cooled by the vegetation layer, the temperature of the air flow entering the agricultural building unit is reduced, and the air flow in the external environment is prevented from flowing into the agricultural building unit and excessively affecting the air temperature environment of the first space.

[0041] Secondly, the agricultural building unit is provided with a support arranged on the outer circumferential side of the frame, and the side wall body is arranged on the support, when the agricultural building unit encounters meteorological disasters such as strong winds and sandstorms, the side ventilation member can close the second air outlet, so that the side wall body becomes a guiding surface inclined to the ground, the first space is prevented from directly encountering the invasion of meteorological disasters such as strong winds and sandstorms, and the ecological safety of the agricultural production in the agricultural building unit is ensured.

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0067] Embodiment 1

[0068] Reference Figures 1-11 , the embodiment 1 of the present application provides an agricultural building unit 100 suitable for marginal land, wherein the marginal land of the embodiment 1 refers to the land which is at or below the break-even point in economy due to the limitation of natural conditions (such as severe climate, poor soil, water shortage, salinization, steep slope, etc.), resulting in high cost, high risk, low and unstable yield in traditional agricultural cultivation, such as desert areas, sandy areas, etc.

[0069] Taking the agricultural building unit 100 built in desert areas and sandy areas as an example, the agricultural building unit 100 of the embodiment 1 comprises a frame 1, a support 7, a top wall body 5, a side wall body 9, a first barrier 11, a second barrier 12 and a plurality of production units 3, wherein the frame 1 can adopt a steel structural member as the structural basis of the present agricultural building unit 100, the frame 1 is connected to the ground, and the top and the peripheral side of the frame 1 are both open, and a first space 2 is formed in the frame 1, and the plurality of production units 3 are arranged in the first space 2, which are inside the frame 1. Each production unit 3 uses the air in the first space 2 as the gas exchange medium for agricultural production, and each production unit 3 can be one of a greenhouse, a breeding farm and an unclosed cultivation field, wherein the greenhouse can be a large greenhouse, a multi-layer greenhouse, a plastic greenhouse, a glass greenhouse, a greenhouse, a sunlight greenhouse, a heating greenhouse and other existing closed greenhouse structures; the unclosed cultivation field can be open field planting, pot planting and other unclosed cultivation fields. 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.

[0070] It should be noted that according to the agricultural production needs of the present agricultural building unit 100, the present agricultural building unit 100 can selectively accommodate greenhouses, breeding farms and unclosed cultivation fields. For example, in some agricultural building units 100, the first space 2 can accommodate a plurality of greenhouses, a plurality of breeding farms or a plurality of unclosed cultivation fields, or can accommodate one greenhouse and one breeding farm, one unclosed cultivation field and one breeding farm, or one unclosed cultivation field and one greenhouse, while in some agricultural building units 100, the first space 2 can accommodate one greenhouse, one breeding farm and one unclosed cultivation field, or can accommodate a plurality of greenhouses, a plurality of breeding farms and a plurality of unclosed cultivation fields.

[0071] In view of the fact that the agricultural building unit 100 is applied to harsh environments such as deserts and sandy land, infrared light and ultraviolet light can easily cause heat accumulation in the first space 2, thereby affecting the operating energy consumption of the production unit 3. In this regard, the agricultural building unit 100 takes the working area of a greenhouse, a farm, or an unclosed cultivation field as the second space 3a in the production unit 3, and at least arranges a blocking layer 4 above the second space 3a, which can be penetrated by visible light and can at least reflect or absorb infrared light and ultraviolet light. The working area of the greenhouse, the farm, or the unclosed cultivation field is the area where the greenhouse, the farm, or the unclosed cultivation field conducts agricultural cultivation.

[0072] It can be understood that when the production unit 3 conducts agricultural activities, air exchange needs to be performed in the second space 3a to meet the growth needs of the plants and animals in the second space 3a. Taking the air in the first space 2 as the gas exchange medium for agricultural production means that when the production unit 3 conducts agricultural activities, the air in the second space 3a takes the air in the first space 2 as the object of gas exchange, and performs gas convection and exchange. For example, when the production unit 3 is a greenhouse, the air in the first space 2 is sucked into the cooling assembly of the greenhouse, and the air in the second space 3a is discharged. When the production unit 3 is a farm or an unclosed cultivation field, the farm or the unclosed cultivation field can be an unclosed place, so that the air in the second space 3a convects and exchanges with the air in the first space 2.

[0073] It can be understood that the heat generated by natural light is mostly from direct radiation of infrared light and ultraviolet light. Therefore, the blocking layer 4 is configured to be able to reflect or absorb at least one of infrared light and ultraviolet light, which can reduce the heat generated by natural light in the second space 3a. In this way, when the agricultural building unit 100 maintains 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, which is conducive to the application of the agricultural building unit 100 to harsh environments such as deserts and sandy land, reduces the cost of agricultural cultivation, and solves the problem of low and unstable yield in marginal land. As an example of this embodiment 1, the blocking layer 4 can be coated with a low-emissivity coating, such as a LOW-E coating, on the wall surface, so that the blocking 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), and let visible light (wavelength between 380 and 780 nm) enter the second space 3a.

[0074] It should be noted that, since the spectrum is continuous, the end point value of two adjacent light waves belongs to the transition zone of the two light waves, for example, the light wave with a wavelength of 380 nm is in the transition zone of visible light and ultraviolet light, and part of the low-emission coating can absorb this light wave, and another part of the low-emission coating can allow this light wave to enter the second space 3a, so the agricultural building unit 100 verifies that the blocking layer 4 is penetrated by visible light and at least one of infrared light and ultraviolet light is reflected or absorbed, and generally the end point of the wave band is not used for verification.

[0075] Reference Figures 1-11 The agricultural building unit 100 of the embodiment 1 has a top wall body 5. The top wall body 5 is connected to the top of the frame 1 to enclose the top of the first space 2, and the top wall body 5 of the embodiment 1 is configured as the blocking layer 4, so that when natural light enters the first space 2 through the top wall body 5, the top wall body 5 as the blocking layer 4 can filter infrared light and ultraviolet light and allow visible light to enter the first space 2, thereby providing light for the growth of plants and animals in the first space 2. Of course, the top wall body 5 also has a first air outlet 6, which is an air outlet for natural ventilation to communicate the first space 2 and the atmospheric environment, so that the first space 2 can have the same / near gas environment as the external atmospheric environment, such as air pressure, oxygen content, carbon dioxide content, etc.

[0076] In the agricultural building unit 100 of the embodiment 1, the top wall body 5 is connected to the top of the frame 1 to form a shelter structure similar to a roof on the top of the frame 1 to enclose the top of the first space 2 and protect the first space 2 and the production unit 3 located in the first space 2 from wind and rain.

[0077] Reference Figures 1-11 The agricultural building unit 100 of the embodiment 1 has a support 7. The support 7 is arranged on the outer circumferential side of the frame 1, and one end of the support 7 is close to the top of the frame 1 and connected to the frame 1, and the other end of the support 7 is connected to the ground, and the part of the frame 1 connected to the ground and the support 7 forms a third space 8, which is arranged on the circumferential side of the first space 2 and on the outer circumferential side of the frame 1 to separate the circumferential side of the first space 2 from the external environment. It should be noted that the support 7 has two opposite ends, and the end of the support 7 close to the top of the frame 1 is the connecting end, which can extend to the top of the frame 1 and be directly connected to the top of the frame 1. Of course, the connecting end can also be connected to the top of the frame 1 through a connecting structure, at this time, the connecting end is not directly connected to the top of the frame 1, but only close to the top of the frame 1.

[0078] Reference Figures 1-11The side wall body 9 is connected to the support 7 to form a shelter structure similar to an outer wall at the support 7 to enclose the third space 8, and the side wall body 9 of the present embodiment 1 is configured to be permeable to visible light and at least one of reflecting or absorbing infrared light and ultraviolet light, so that in the agricultural building unit 100 of the present embodiment 1, the side wall body 9 cooperates with the top wall body 5 to effectively block infrared light / ultraviolet light from entering the first space 2, thereby effectively reducing the heat generated in the first space 2 due to natural light. As an example of the present embodiment 1, the side wall body 9 can also be coated with a low-emissivity coating, such as a LOW-E coating, on the wall surface to achieve the light-transmitting and blocking effect of the barrier layer 4.

[0079] To improve the flow of air in the present agricultural building unit 100, the side wall body 9 has a second air inlet 10 to form a second air inlet 10 for introducing natural air flow. The side wall body 9 forms the second air inlet 10 in various ways, for example, as an example of the present embodiment 1, the side wall body 9 includes a side ventilation member 9a that can be opened and closed relative to the support 7, and when the side ventilation member 9a is opened relative to the support 7, the second air inlet 10 for introducing natural air flow is formed. The second air inlet 10 can be arranged along the entire height of the side wall body 9, or only at a portion of the height of the side wall body 9, but at least a portion of the second air inlet 10 is arranged near the ground to form an air inlet for natural ventilation. It should be noted that the side ventilation member 9a of the present embodiment 1 is part of the side wall body 9 of the present embodiment 1, so the side ventilation member 9a of the present embodiment 1 is also permeable to visible light and at least one of reflecting or absorbing infrared light and ultraviolet light.

[0080] It should be noted that the arrangement of at least a portion of the second air inlet 10 near the ground does not require the second air inlet 10 to be in close contact with the ground. Depending on the environmental conditions of the area where the present agricultural building unit 100 is located, in some agricultural building units 100, the second air inlet 10 can be arranged at a height of 0.5 to 1 meters from the ground. Of course, in an environment where the ground temperature is not too high, the second air inlet 10 of some agricultural building units 100 can be arranged at a height of 0.1 to 0.5 meters from the ground.

[0081] In the harsh environment such as desert, sandy land, in addition to the high temperature of atmospheric environment, the long-wave radiation of the ground, the erosion of pests and other problems are also important factors affecting the normal development of agricultural production. Therefore, the agricultural building unit 100 needs to separate the internal space of the agricultural building unit 100 from the external environment in the harsh environment such as desert, sandy land, and so on. Therefore, the first blocking piece 11 is arranged 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 spaced from the ground of the external environment. In this way, under the cooperation of the frame 1, the top wall body 5, the side wall body 9, the support piece 7 and the first blocking piece 11, the frame 1 and the top wall body 5 cooperate to space the top of the first space 2 from the atmospheric environment, the support piece 7 and the side wall body 9 cooperate to space the third space 8 from the atmospheric environment, and the first blocking piece 11 spaces the bottom of the first space 2 from the atmospheric environment and spaces the bottom of the third space 8 from the atmospheric environment, so that the agricultural building unit 100 of the embodiment 1 encloses the first space 2 and the third space 8 in the atmospheric environment to form an environment space more suitable for agricultural cultivation than the atmospheric environment.

[0082] As an example of the embodiment 1, the first blocking piece 11 can adopt a design capable of allowing water and / or air to pass through, such as a plastic cloth capable of allowing water and air to pass through, such as a weed cloth. The number of plastic cloths arranged can be determined according to the situation of the external environment, so as to avoid water accumulation in the first blocking piece 11 and prevent pests in the external environment from entering the agricultural building unit 100 through the ground. Of course, the first blocking piece 11 can also adopt a design capable of blocking water and air, and a drainage facility such as a drainage ditch can be constructed on the first blocking piece 11 to avoid water accumulation in the first blocking piece 11 and prevent pests in the external environment from entering the agricultural building unit 100 through the ground.

[0083] Through the cooperation of the frame 1, the blocking layer 4, the top wall body 5, the side wall body 9, the support piece 7 and the first blocking piece 11, the agricultural building unit 100 can space the first space 2 and the third space 8 from the external environment, reduce the influence of environmental factors such as high temperature and strong wind on the first space 2 and the third space 8, and make the first space 2 and the third space 8 cooperate to form a space more suitable for agricultural cultivation than the atmospheric environment of the desert region. In addition, the first blocking piece 11 spaces the area where the production unit 3 is located and the area between the adjacent two production units 3 from the ground of the external environment, so that the agricultural building unit 100 can construct an agricultural cultivation space with more optimal environmental conditions in the harsh environment such as sandy region and desert region, so that the agricultural building unit 100 can take the first space 2 as the basic environment for agricultural production, and by accommodating multiple production units 3 in the first space 2, the agricultural building unit 100 can construct a greenhouse, a breeding farm and a non-enclosed cultivation field in the harsh environment.

[0084] It should be noted that by configuring the top wall body 5 and the side wall body 9 to be able to be penetrated by visible light and at least one of reflecting or absorbing infrared light and ultraviolet light, the temperature rise of the first space 2 and the third space 8 caused by direct radiation of infrared light and ultraviolet light can be reduced, thereby reducing the heat accumulation of the first space 2 and the third space 8 caused by natural lighting. Further, by spacing the first space 2 and the third space 8 from the ground of the external environment by the first barrier 11, the secondary radiation of the ground of the external environment to the first space 2 and the third space 8 can be effectively inhibited, and the heat accumulated in the first space 2 and the third space 8 during the natural lighting period is comprehensively reduced, so that the agricultural building unit 100 is adapted to high-temperature and arid environments such as sandy land and desert.

[0085] Moreover, under the cooperation of the top wall body 5 and the side wall body 9, the light and heat absorbed by the first barrier 11 is lower than that of the ground of the external environment, and the temperature of the first barrier 11 will be much lower than the surface temperature of the sunlight, so that the long-wave radiation of the first barrier 11 to the first space 2 and the third space 8 can be reduced, thereby forming an air temperature environment in which the internal temperature of the first space 2 and the third space 8 is lower than the atmospheric environment temperature, and in particular, the temperature of the first barrier 11 can be much lower than the ground temperature of the external environment. For example, in a high-temperature region where the atmospheric temperature of the external environment reaches 45-48℃, the temperature of the side of the top wall body 5 facing the ground can be reduced to 36-38℃, the temperature of the first space 2 can be reduced to 30-32℃, and the temperature of the first barrier 11 can be reduced to 24-26℃.

[0086] It should be noted that in a natural lighting environment, the heat accumulation efficiency of the first space 2 and the third space 8 is different. The first space 2 is the area where the agricultural production activities of the agricultural building unit 100 are carried out, so the first space 2 will accumulate carbon dioxide, biological heat energy, and hot gas discharged by the refrigeration system generated by plants and animals, and 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 on the inner side of the frame 1, and the third space 8 is located between the support 7 and the frame 1 and on the outer side of the frame 1, the third space 8 will not be too close to the heat radiation influence area of the first space 2, which will make the heat accumulated in the third space 8 less than that accumulated in the first space 2. Due to the slow heat exchange rate of air itself, within a certain time of opening natural ventilation, the temperature of the third space 8 will be lower than that of the first space 2, so that the third space 8 in this time period will form a temperature rise lag area relative to the first space 2, i.e., the temperature rise rate of the third space 8 in this time period will be less than that of the first space 2, thereby forming a low-temperature area arranged on the side of the first space 2. It should be noted that the heat radiation influence area of the first space 2 refers to the effective range of heat radiation to the outside by the greenhouse, breeding farm, and non-enclosed cultivation field in the first space 2.

[0087] It should be noted that in the natural light environment, the heat of the environment mainly comes from the direct radiation of infrared light and ultraviolet light and the long-wave radiation after the ground absorbs heat. The heat conduction rate of air itself is far lower than the heat conduction efficiency of infrared light, ultraviolet light and ground heat radiation. Therefore, under the cooperation of the blocking layer 4, the side wall body 9 and the first blocking piece 11, the temperature of the first space 2 will be lower than that of the external environment. In this way, when the greenhouse, the breeding farm and the non-closed cultivation field are contained in the first space 2, the greenhouse, the breeding farm and the non-closed cultivation field are temperature-controlled in the air temperature environment of the first space 2 with the air in the first space 2 as the gas exchange medium. Compared with the temperature difference caused by the traditional greenhouse directly exposed to the atmospheric environment, the greenhouse, the breeding farm and the non-closed cultivation field built in the first space 2 need to overcome a smaller temperature difference value. For example, for a greenhouse whose internal temperature needs to be controlled at 24°C, when the atmospheric temperature of the external environment reaches 45-48°C and the temperature of the first space 2 is 30-32°C, the temperature difference value that the temperature control assembly needs to overcome is only 6-8°C. Compared with the temperature difference value of 21-24°C that needs to be overcome in the greenhouse in the external environment, the agricultural building unit 100 can effectively reduce the temperature control cost of the greenhouse, the breeding farm and the non-closed cultivation field, save the operation energy consumption of the greenhouse, the breeding farm and the non-closed cultivation field, and effectively improve the input-output ratio of the agricultural building unit 100 in the marginal land such as sand land and desert for agricultural cultivation.

[0088] It should be noted that in the state that the first air outlet 6 and the second air outlet 10 are opened, air will enter the third space 8 from the second air outlet 10 and leave the first space 2 from the first air outlet 6, so that the second air outlet 10 forms a natural ventilation air inlet and the first air outlet 6 forms a natural ventilation air outlet. On the one hand, this is because the greenhouse, the breeding farm and the non-closed cultivation field contained in the first space 2 will accumulate heat, and the carbon dioxide and biological heat generated by plants and animals and the hot gas discharged by the refrigeration system will cause the temperature of the first space 2 to rise. Since the resistance of vertical airflow is smaller than that of horizontal airflow, the air in the first space 2 that is heated and expanded will preferentially flow vertically and continuously escape from the first air outlet 6 to the external environment, which will cause the air pressure in the first space 2 to decrease slightly, thereby causing the first space 2 to continuously suck the air in the third space 8, which in turn causes the air pressure in the third space 8 to decrease slightly and the air near the second air outlet 10 to flow into the agricultural building unit 100. On the other hand, since the ground of the external environment is warmed by direct sunlight, the near-ground air near the agricultural building unit 100 will preferentially flow vertically, causing the near-ground air to quickly rise after being heated, forming a strong upward airflow, and causing a large area near the agricultural building unit 100 to form a low-pressure zone, thereby causing air at a higher altitude to supplement the near-ground area. However, due to the obstruction of the agricultural building unit 100, air at a higher altitude away from the agricultural building unit 100 will preferentially supplement the near-ground area to the air above the agricultural building unit 100, thereby forming a natural airflow blowing towards the agricultural building unit 100. The natural airflow blowing towards the agricultural building unit 100 enters the third space 8 from the second air outlet 10, exchanges heat with the first partition 11 and the air in the third space 8, and then flows into the first space 2 and leaves the agricultural building unit 100 through the first air outlet 6, thereby forming a natural top-down ventilation airflow in the agricultural building unit 100, which in turn carries away the air with a lower temperature that settles near the third space 8 and the first partition 11 and diffuses to the first space 2 within a certain time of opening the natural ventilation, thereby quickly reducing the ambient temperature of the first space 2. In this way, the temperature control cost of the greenhouse, the breeding farm and the non-closed cultivation field constructed in the first space 2 can be further effectively reduced, and the operating energy consumption of the greenhouse, the breeding farm and the non-closed cultivation field can be saved. Figure 3 As shown in the figure, the natural top-down ventilation airflow in the agricultural building unit 100, which in turn carries away the air with a lower temperature that settles near the third space 8 and the first partition 11 and diffuses to the first space 2 within a certain time of opening the natural ventilation, thereby quickly reducing the ambient temperature of the first space 2. In this way, the temperature control cost of the greenhouse, the breeding farm and the non-closed cultivation field constructed in the first space 2 can be further effectively reduced, and the operating energy consumption of the greenhouse, the breeding farm and the non-closed cultivation field can be saved.

[0089] Considering that the daytime temperature in high-temperature and arid regions such as desert regions and sandy regions is relatively high, the agricultural building unit 100 can also be configured with more cooling measures. For example, referring to Figures 1-11As an example of the present embodiment 1, the agricultural building unit 100 further comprises a second barrier 12 located at the outer circumferential side of the side wall body 9, and the second barrier 12 is provided with a vegetation layer 13 adjacent to the second air outlet 10 close to the ground, so that the natural ventilation air flow flowing into the agricultural building unit 100 from the external environment flows along the vegetation layer 13, the second air outlet 10, and the first air outlet 6 in sequence, forming a natural ventilation path as shown in the figure. Figure 3

[0090] It can be understood that the vegetation layer 13 is connected with a water source to provide water required for the growth of the vegetation layer 13, such as providing vegetation water to the vegetation layer 13 through a drip irrigation system. 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 lower temperature than the atmospheric environment. By arranging the vegetation layer 13 adjacent to the second air outlet 10 close to the ground, the vegetation layer 13 can cooperate with the third space 8 to form a dynamic and stable local low-temperature environment similar to a tree shade area, so that the air passing through the vegetation layer 13 can directly enter the third space 8, avoiding the air passing through the vegetation layer 13 to exchange heat with the ground of the external environment again. In addition, the vegetation layer 13 close to the second air outlet 10 can reduce the wind speed entering the agricultural building unit 100, so that the speed of the air of the external environment entering the agricultural building unit 100 is greatly slowed down, and the air flow of the external environment can exchange heat with the vegetation layer 13 when passing through the vegetation layer 13, so that the air flow entering the agricultural building unit 100 is pre-cooled by the vegetation layer 13, the temperature of the air flow entering the agricultural building unit 100 is reduced, and the influence of the external hot air flow flowing into the agricultural building unit 100 on the air temperature environment of the first space 2 is avoided.

[0091] ​It should be noted that the agricultural building unit 100 of the present embodiment 1 forms a dynamically stable air temperature environment as a whole through the cooperation of the first space 2, the third space 8, the first air outlet 6, the second air outlet 10, the first barrier 11, the second barrier 12 and the vegetation layer 13. Specifically, the air temperature environment is weakened by the direct radiation of sunlight through the cooperation of the barrier layer 4 and the side wall 9, the erosion of factors unsuitable for cultivation through the cooperation of the first barrier 11 and the second barrier 12, and the reduction of ground heat absorption and ground secondary radiation in the area where the agricultural building unit 100 is located through the cooperation of the barrier layer 4, the side wall 9, the first barrier 11 and the second barrier 12. The first space 2, the third space 8, the first air outlet 6 and the second air outlet 10 cooperate to form an area that can accommodate a greenhouse, a breeding farm and an unclosed cultivation field, so that the agricultural building unit 100 can use natural wind to form a natural air flow flowing from bottom to top, diffuse the relatively cold air in the first space 2 and the third space 8 to the entire first space 2, reduce the environmental temperature of the first space 2, and make the air index of the first space 2 close to or equal to the air index of the external environment, so that the agricultural building unit 100 can build a local environment suitable for agricultural production in an environment unsuitable for agricultural production, and solve the problem of marginal land unsuitable for agricultural production in harsh environments.

[0092] Moreover, in the agricultural building unit 100 with 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 vegetation layer 13 planting, so that the agricultural building unit 100 forms a closed-loop production operation mode, reduces the input cost of maintaining agricultural production of the agricultural building unit 100, and improves the output of agricultural production in harsh environments.

[0093] It should be noted that the agricultural building unit 100 is applied to harsh environments, and may encounter weather disasters such as strong winds and sandstorms. Some agricultural building units 100 can use the support 7 to build a windproof and flow guiding structure, for example, referring to Figure 1 and Figure 7, one end of the support 7 is close to the top of the frame 1 and connected to the frame 1, the other end of the support 7 is connected to the ground, and the spacing between the support 7 and the frame 1 decreases from the end of the support 7 connected to the ground to the end of the support 7 close to the top of the frame 1, so that the support 7 can serve as an auxiliary support structure of the frame 1, enhance the structural strength of the agricultural building unit 100, and by arranging the support 7 on the outer circumferential side of the frame 1 and arranging the side wall body 9 on the support 7, when the agricultural building unit 100 encounters weather disasters such as strong winds and sandstorms, the side ventilation piece 9a can close the second air port 10, so that the side wall body 9 becomes a guide surface inclined to the ground, guiding the strong wind to the upper part of the agricultural building unit, slowing down the direct impact of the strong wind and sand on the agricultural building unit 100, avoiding the direct impact of the first space 2 on the strong wind, sandstorm and other weather disasters, and ensuring the ecological safety of the internal agricultural production of the agricultural building unit 100.

[0094] In some agricultural building units 100, the production unit 3 is a breeding farm and an unclosed cultivation farm. In order to provide the soil environment required by the breeding farm and the unclosed cultivation farm, a substrate layer 14 can be arranged on the first barrier 11, so that the substrate layer 14 forms the bottom of the second space 3a. For example, external soil or external sandy soil different from the external environment land can be arranged on the first barrier 11 as the substrate layer 14 of the agricultural building unit 100, so that the agricultural building unit 100 can plant temperate crops in a soil culture way in high-temperature and drought tropical regions such as sandy regions and desert regions, greatly reducing the planting cost of cross-regional planting. Of course, in the agricultural building unit 100 containing a greenhouse in the first space 2, the substrate layer 14 can also constitute the ground of the greenhouse, and the greenhouse can adopt the existing traditional greenhouse structure.

[0095] Considering that the greenhouse arranged in the first space 2 may need to adjust the light, in some agricultural building units 100, a greenhouse can also be considered to be built in the first space 2, and a louver can be used as a window for air flow between the greenhouse and the first space 2. The louver in this type of greenhouse can block sunlight from entering the greenhouse, for example, in the case of too strong sunlight, the louver can be adjusted to be partially opened or completely closed, thereby reducing the light entering the greenhouse. Of course, the agricultural building unit 100 arranged with the greenhouse and the greenhouse can also arrange a three-dimensional device in the greenhouse and the greenhouse to fully utilize the planting space inside the greenhouse and the greenhouse.

[0096] It should be noted that in the case of strong sunlight, such as during the sun hours, the first air outlet 6 and the second air outlet 10 of the agricultural building unit 100 will generally be maintained in an open state, so that the first space 2 and the third space 8 maintain a dynamically stable air temperature environment. Therefore, the first space 2 of the agricultural building unit 100 is not the internal space of a greenhouse, a shed or the like structure, but an external space accommodating the greenhouse, the shed or the like. For example, the first space 2 can simultaneously accommodate several greenhouses and several farms, such as glass greenhouses, double-layer greenhouses, chicken farms or the like, thereby forming a local ecological circle with a temperature different from the external atmospheric environment. By arranging multiple production units 3 in the first space 2 and separating the external environment by the top wall 5, the side wall 9 and the first partition 11, the agricultural building unit 100 can construct a farm environment suitable for agricultural cultivation inside the frame 1. In this way, the production units 3 arranged in the first space 2 can take the air temperature environment of the first space 2 as the basic environment for their own temperature management, thereby achieving low-energy-consumption management and avoiding the production units 3 in the first space 2 taking the external atmospheric environment as the basic environment for their own temperature management, which greatly increases the energy consumption for temperature management under the influence of the external high-temperature environment. Of course, the first space 2 can also be configured with other auxiliary units for agricultural cultivation, such as a soil preparation center, to provide suitable soil for agricultural cultivation, so that the agricultural building unit 100 can carry out agricultural production activities in harsh environments.

[0097] It can be understood that different environments will have different requirements for the protection performance of the agricultural building unit 100. For example, in some environments, the agricultural building unit 100 needs better air discharge capacity to resist the wind flow of the external environment. Referring to Figures 2-4 , Figure 2 the black arrows in the figure indicate the direction of the air flow, Figure 4 the white arrows in the figure indicate the direction of the sunlight, Figure 4 the line arrows in the figure indicate the reflection direction of the infrared light, and the side wall 9 can include multiple side ventilation members 9a and multiple side light-transmitting members 9b. The multiple side light-transmitting members 9b are fixedly connected with the support member 7, and at least part of the side light-transmitting members 9b are arranged in intervals with part of the side ventilation members 9a. By fixing the side light-transmitting members 9b on the support member 7, the side wall 9 can have higher structural strength, so that the agricultural building unit 100 can resist a larger wind flow of the external environment. It should be noted that the side light-transmitting members 9b also belong to part of the side wall 9, so the side light-transmitting members 9b can also be penetrated by visible light and at least reflect or absorb one of infrared light and ultraviolet light. Of course, the side wall 9 of some agricultural building units 100 can also be composed of only side light-transmitting members 9b. In this type of side wall 9, the second air outlet 10 can be considered to be arranged in an open manner and be provided with a heat insulation measure such as a heat preservation blanket. In the case that the air temperature of the external environment decreases to be unsuitable for crop growth, the second air outlet 10 is closed.

[0098] As an example of Embodiment 1, the side light 9b can also be a solar panel. In order to avoid the side light 9b affecting the air temperature environment of the first space 2 and the third space 8, the solar panel used by the side light 9b is suitably configured to be able to be penetrated by visible light and at least one of reflect or absorb infrared light and ultraviolet light, for example, a LOW-E coating is applied on the solar panel. Of course, considering the large diurnal temperature difference in desert, sandy land and other environments, the side light 9b can also consider using heat insulation glass to reduce the influence of the external environment on the air temperature environment of the first space 2.

[0099] The top wall 5 has various configurations to adapt to different environments. Referring to Figure 7 As an example of Embodiment 1, the top wall 5 of the agricultural building unit 100 includes a top ventilation piece 5a, which can be opened and closed relative to the frame 1 to form the first air opening 6, and the top ventilation piece 5a can be penetrated by visible light and at least one of reflect or absorb infrared light and ultraviolet light to form the barrier layer 4. The top ventilation piece 5a can be controlled to open and close by a motor or the like. By opening and closing the top ventilation piece 5a relative to the frame 1, the opening and closing degree of the first air opening 6 relative to the frame 1 can be adjusted, so that the agricultural building unit 100 can adjust the air temperature environment of the first space 2, and by making the top ventilation piece 5a reflect or absorb one of infrared light and ultraviolet light, the heat accumulated in the first space 2 due to natural light can be reduced, the heat accumulation in the first space 2 can be reduced, and the air temperature used for circulation in the second space 3a can be reduced. In this type of agricultural building unit 100, the greenhouse contained in the first space 2 can use a film greenhouse. Of course, according to the needs of the crops planted in the greenhouse and the external environment, the greenhouse contained in the first space 2 can also use a glass greenhouse, and the glass is configured to be able to be penetrated by visible light and at least one of reflect or absorb infrared light and ultraviolet light.

[0100] It should be noted that the top ventilation piece 5a can be coated with a low-emissivity coating, such as a LOW-E coating, on the wall surface, so that the barrier layer 4 can reflect far-infrared light (wavelength > 2500 nm), reflect near-infrared light (wavelength between 780-2500 nm) and absorb ultraviolet light (wavelength between 100-380 nm), and let visible light (wavelength between 380-780 nm) into the first space 2.

[0101] In some agricultural building units 100, referring to Figures 8-9The top wall body 5 can also include a plurality of top ventilation pieces 5a and a plurality of top light-transmitting pieces 5b to enhance the strength of the top wall body 5. The top light-transmitting pieces 5b are fixed above the first space 2 and can be penetrated by visible light and at least one of infrared light and ultraviolet light to form a barrier layer 4. The top light-transmitting pieces 5b are arranged in intervals with the top ventilation pieces 5a, which can save the number of top ventilation pieces 5a arranged, thereby saving the assembly cost of the agricultural building unit 100. In addition, the distribution position of the top ventilation pieces 5a can be adjusted according to the greenhouse, breeding farm, and non-enclosed cultivation field contained in the first space 2, which can ensure that the first air vents 6 formed by the top ventilation pieces 5a meet the ventilation needs of the first space 2. The blocking effect of the top light-transmitting pieces 5b on sunlight is the same as that of the top ventilation pieces 5a, which will not be described here. Of course, the top wall body 5 can also be composed of only a plurality of top light-transmitting pieces 5b. In this type of top wall body 5, the first air vents 6 can also be considered to be arranged open and insulated by thermal insulation measures such as thermal insulation blankets, so that the first air vents 6 can be closed when the external environment temperature drops to an unsuitable temperature for crop growth.

[0102] It should be noted that in the agricultural building unit 100 using top light-transmitting pieces 5b to construct the top wall body 5, the first air vents 6 can be arranged open. In this type of agricultural building unit 100, the top ventilation pieces 5a can be arranged at the first air vents 6, or other structures can be considered. For example, as an example of the present embodiment 1, referring to Figure 10 In this type of agricultural building unit 100, the top wall body 5 can also include a plurality of top light-transmitting films 5d, which can be penetrated by sunlight and movably connected to the first air vents 6 to open and close the first air vents 6. The top light-transmitting films 5d can control the opening degree of the first air vents 6 by means of motor winding. Considering that some agricultural building units 100 may have heat preservation needs during the sunset period, the top light-transmitting films 5d can be arranged with thermal insulation films. Compared with the investment cost of the top ventilation pieces 5a, the investment cost of the top light-transmitting films 5d is lower, which is conducive to reducing the investment cost of the agricultural building unit 100.

[0103] According to the lighting needs of the agricultural building unit 100 and the temperature environment of the external environment, the top wall body 5 selectively uses the top ventilation pieces 5a, the top light-transmitting pieces 5b, and the top light-transmitting films 5d for cooperation. For example, in some agricultural building units 100, the top wall body 5 can simultaneously use the top light-transmitting pieces 5b and the top light-transmitting films 5d for configuration. Of course, since the top light-transmitting films 5d do not filter infrared light and ultraviolet light, in high-temperature and arid areas such as sandy land and desert, the top wall body 5 can also consider using the top ventilation pieces 5a, the top light-transmitting pieces 5b, and the top light-transmitting films 5d in cooperation, which can reduce the amount of infrared light and ultraviolet light entering the first space 2.

[0104] In the agricultural building unit 100 in which the side wall body 9 is provided with the side ventilation member 9a, the side ventilation member 9a at least constitutes part of the outer wall of the agricultural building unit 100 and is subjected to the irradiation of natural light. In order to reduce the heat conduction between the external environment and the first space 2 and the third space 8 and maintain the local low-temperature environment of the first space 2 and the third space 8, the side ventilation member 9a can be designed to have heat insulation. Referring to Figure 11 As an example of the present embodiment 1, the side ventilation member 9a includes a first end side 9a1 and a second end side 9a2, the first end side 9a1 and the second end side 9a2 mutually enclosing a cavity 9a3, and the first end side 9a1 has a first segment 9a10 and a second segment 9a11 connected to each other, and both the first segment 9a10 and the second segment 9a11 gradually converge from the connection position thereof toward the second end side 9a2. The first segment 9a10 and the second segment 9a11 can be planar structures, which are conducive to the cooperation of the side ventilation member 9a with the adjacent side light-transmitting member 9b or the adjacent another side ventilation member 9a, forming a flow guide surface in the case that the adjacent two side ventilation members 9a are closed, thereby guiding the airflow to flow along the side wall body 9. In addition, considering that part of the agricultural building unit 100 needs to resist strong winds through the side ventilation member 9a, in part of the side ventilation member 9a, a reinforcing rib 9a4 can be arranged in the cavity 9a3, and 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 member 9a.

[0105] Through the cooperation of the second end side 9a2, the first end side 9a1 and the cavity 9a3, the side ventilation member 9a can slow down the invasion of heat from the external environment into the third space 8 and reduce the heat conduction between the third space 8 and the external environment. In addition, in the case that the two side ventilation members 9a adjacent in the height direction are opened, the first segment 9a10 between the two side ventilation members 9a and the second segment 9a11 between the two side ventilation members 9a can form a horn mouth, thereby forming a narrow tube effect between the two side ventilation members 9a and accelerating the flow of external air into the third space 8.

[0106] Of course, the top ventilation member 5a can also have the same structure as the side ventilation member 9a, that is, the top ventilation member 5a includes a third end side and a fourth end side, the third end side and the fourth end side mutually enclosing a cavity, and the third end side has a third segment and a fourth segment connected to each other, and both the third segment and the fourth segment gradually converge from the connection position thereof toward the fourth end side, wherein 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 member 5a also has the blocking and flow guiding effect of the side ventilation member 9a, which will not be described in detail here.

[0107] Considering the fact that the sunlight in desert and sandy land is sufficient, and the air temperature in desert can reach 50℃ or above under the sunlight, the agricultural building unit 100 can need to add blocking structure outside the top wall 5, and considering the fact that the energy consumption in agricultural production in greenhouse, breeding farm and non-closed cultivation field, the agricultural building unit 100 can be provided with photovoltaic group 15. The photovoltaic group 15 can provide shading and blocking for the top wall 5, and provide green energy for agricultural production.

[0108] With reference to Figure 1 , the agricultural building unit 100 in this embodiment 1 is provided with photovoltaic group 15, which is above the frame 1 and connected to the top of the frame 1. The photovoltaic group 15 at least includes a plurality of photovoltaic panels 15a, which can be connected to the electrical equipment in the first space 2. In this way, the solar energy can be recycled by the photovoltaic panels 15a, which can at least provide part of the electrical energy required for agricultural production of the agricultural building unit 100, and provide appropriate shading and blocking for the top wall 5.

[0109] It should be noted that the spacing distance between the photovoltaic panels 15a in the agricultural building unit 100 is configured according to the light intensity inside the first space 2, rather than according to the solar energy recycling of the photovoltaic panels 15a. Therefore, the spacing distance between the photovoltaic panels 15a in the agricultural building unit 100 can be equal to the commonly used spacing distance of other photovoltaic panels 15a, or can be greater than the commonly used spacing distance of other photovoltaic panels 15a.

[0110] In order to facilitate the assembly of the top wall 5 and reduce the wind resistance of the top wall 5, in some agricultural building units 100, the top of the frame 1 can be provided with a flat structure layer, and the top wall 5 is connected to the structure layer. For example, as an example of this embodiment 1, with reference to Figure 1 , the top of the frame 1 is provided with a flat structure layer, and the top wall 5 is arranged along the extension direction of the flat structure layer, thereby separating the top of the first space 2 and the external environment. Of course, there are many ways to form the flat structure layer of the frame 1. For example, as an example of this embodiment 1, the frame 1 includes a plurality of columns 1a and a plurality of top beams 1b. The plurality of columns 1a are vertically arranged, and the plurality of top beams 1b are connected to the top of the columns 1a to form a flat structure layer.

[0111] It should be noted that the flat structure layer of the frame 1 is a frame structure arranged in the horizontal direction, so that the top of the frame 1 is at the same horizontal height. For example, the plurality of top beams 1b are arranged in the horizontal direction, and the plurality of top beams 1b are connected to each other to form a frame structure similar to a window frame, so that the top of the frame 1 is open, and the top of the frame 1 forms a frame structure arranged in the horizontal direction, i.e. a flat structure layer. The top wall 5 is installed in this flat structure layer, which can also make the top wall 5 form a wall arranged in the horizontal direction, thereby reducing the wind resistance of the top wall 5.

[0112] Example 2

[0113] 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 provided below the top wall 5 and arranged in 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 be able to be penetrated by sunlight.

[0114] refer to Figures 12-14 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 light 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 forms the top of the second space 3a. Alternatively, the partition 19 is located above the second space 3a, and a separate plate is configured at the top of the second space 3a.

[0115] refer to Figures 12-14 As an example of arranging a barrier layer 4 in the first space 2, in some agricultural building units 100, a sun panel as a partition 19 is provided in the first space 2. The sun panel is spaced apart from the top wall 5 and is away from the heat radiation affected zone of the top wall 5 to prevent the heat generated by the top wall 5 under sunlight from increasing the energy consumption of the greenhouse. The sun panel cooperates with the first barrier 11 to form a second space 3a in the first space 2. The second space 3a is separated from the first space 2, and the sun panel is constructed to be able to be passed by visible light and to reflect or absorb at least one of infrared light and ultraviolet light to form a barrier layer 4. It should be noted that the heat radiation affected zone of the top wall 5 refers to the effective range of the top wall 5 that heats up due to sunlight and radiates heat to the outside world.

[0116] The aforementioned solar panels can be coated with a low-emissivity coating, such as a Low-E coating, to achieve light transmission and infrared and ultraviolet light filtering. Using these panels allows for the creation of an enclosed planting area within the first space 2. Furthermore, the multiple barriers and shading effects created by the partitions 19 and the top wall 5 effectively reduce energy consumption for cooling the second space 3a. To maintain the temperature within the greenhouse, the second space 3a can also be equipped with a temperature control component, such as an air conditioning system using an air-source heat pump.

[0117] Of course, in some agricultural building units 100, the sun panel serving as the top wall of the second space 3a may also be capable of transmitting only sunlight. In this type of agricultural building unit 100, a light-transmitting panel coated with a low-emissivity coating is disposed between the sun panel and the top wall 5, and a barrier layer 4 can also be disposed within the first space 2.

[0118] It is noted that in the agricultural building unit 100 of the present embodiment 2, the top wall 5 can still be formed by the top ventilation member 5a and / or the top light-transmitting member 5b and / or the top light-transmitting film 5d. Of course, in the agricultural building unit 100 of the present embodiment 2, the top ventilation member 5a and the top light-transmitting member 5b do not need to be coated with a low-emissivity coating so that the top ventilation member 5a and the top light-transmitting member 5b can be penetrated by sunlight and do not reflect or absorb infrared light and ultraviolet light.

[0119] It is noted that in some agricultural building units 100, the partition 19 of the present embodiment 2 can be used in combination with the top wall 5 of the first embodiment 1, for example, in this type of agricultural building unit, part of the top wall 5 is formed by the top ventilation member 5a and the top light-transmitting member 5b coated with a low-emissivity coating to form part of the barrier layer 4, and in this type of agricultural building unit 100, the partition 19 is arranged in the first space 2 to form the remaining part of the barrier layer 4.

[0120] The other structures of the present embodiment 2 are the same as those of the first embodiment 1, which will not be described here.

[0121] Embodiment 3

[0122] The difference between the present embodiment 3 and the first embodiment 1 is that, referring to Figure 15 , the agricultural building unit 100 of the present embodiment 3, the photovoltaic panels 15a are arranged at an inclination, i.e. the photovoltaic panels 15a are inclined to the top of the frame 1 and are connected to the top of the frame 1 by the mounting rack, and a plurality of photovoltaic panels 15a are arranged in an array, and adjacent two photovoltaic panels 15a have a first spacing channel 16 and the first light-transmitting channel 17 that are in communication with each other.

[0123] It is noted that the first spacing channel 16 refers to the spacing channel of adjacent two photovoltaic panels 15a in the arrangement direction. In the case of the photovoltaic panels 15a being installed at an inclination, the length of the first spacing channel 16 is usually the distance between adjacent two photovoltaic panels 15a that are not blocked by each other when being irradiated by the sun during 9:00-15:00 on the winter solstice day. The existing photovoltaic panels 15a are usually arranged with the first spacing channel 16 as the spacing to obtain the maximum light-irradiated area.

[0124] In the agricultural building unit 100 of the present embodiment 3, the light intensity of the first space 2 may not meet the light demand of agricultural production under the shading effect of the photovoltaic panel 15a, so the agricultural building unit 100 is additionally provided with a first light-transmitting channel 17 between the adjacent two photovoltaic panels 15a in addition to the first spacing channel 16, so that sunlight can enter the first space 2 from the first light-transmitting channel 17, and the light-transmitting area between the adjacent two photovoltaic panels 15a is sufficient to meet the light intensity demand of the first space 2, and provides shading and blocking for the top wall 5. Of course, in some agricultural building units 100, at least part of the first air outlet 6 can be arranged between the adjacent two rows of photovoltaic groups 15, and the light can be transmitted through the opened first air outlet 6, so as to improve the light intensity of the first space 2. The number of the first air outlet 6 arranged between the adjacent two rows of photovoltaic groups 15 can be adjusted according to the light intensity required by the first space 2 and the sunshine condition of the external environment.

[0125] It should be noted that the photovoltaic panel 15a will generate a certain amount of heat during work. Since the photovoltaic panel 15a is located above the frame 1 and connected to the top of the frame 1, the photovoltaic panel 15a can be close to the first air outlet 6 of the top wall 5, which affects the air exhaust of the first space 2, so in some agricultural building units 100, the photovoltaic panel 15a can be arranged in a higher altitude area, for example, referring to Figure 15 , the side of the photovoltaic panel 15a facing the frame 1 is spaced apart from the top wall 5 to form a ventilation channel 18; the ventilation channel 18 is in communication with the first spacing channel 16 and the first light-transmitting channel 17, and the ventilation channel 18 is below the heat radiation influence area of the photovoltaic panel 15a.

[0126] It should be noted that the heat radiation influence area of the photovoltaic panel 15a refers to the effective range of heat radiation of the heat source generated by the normal work of the photovoltaic panel 15a to the outside. By spacing the side of the photovoltaic panel 15a close to the frame 1 from the top wall 5, and making the ventilation channel 18 below the heat radiation influence area of the photovoltaic panel 15a, the photovoltaic panel 15a can be fully away from the top wall 5, avoiding the air flowing out of the first air outlet 6 to be affected by the heat radiation influence area of the photovoltaic panel 15a to become turbulent, and the photovoltaic panel 15a can also provide shading and blocking for the top wall 5.

[0127] The other structures of the present embodiment 3 are the same as those of the embodiment 1, which will not be described here.

[0128] Embodiment 4

[0129] The difference between the present embodiment 4 and the embodiment 2 is that, referring to Figures 16-17The top wall body 5 of the agricultural building unit 100 of this embodiment 4 is connected to the top of the frame 1, wherein the top wall body 5 comprises a flow guide part 5c arranged obliquely to the ground, and the flow guide part 5c has oppositely arranged first and second ends 5c1 and 5c2, the first end 5c1 is close to the side of the frame 1 facing the first space 2, and the second end 5c2 extends above the frame 1, so that the flow guide part 5c and the frame 1 form a flow guide space 20 above the first space 2; the second end 5c2 and the frame 1 form a first air inlet 6 on the side of the flow guide part 5c facing the first space 2.

[0130] It can be understood that the flow guide part 5c can be formed by one of the top light-transmitting part 5b and the top light-transmitting film 5d, or formed by cooperation between the top light-transmitting part 5b and the top light-transmitting film 5d. By arranging the flow guide part 5c obliquely to the ground, a windproof and flow guide structure can be formed above the frame 1. For example, in the agricultural building unit 100 arranged towards the north side, the wind coming from the north side and having a height close to the top of the frame 1 will flow upwards along the guide of the flow guide part 5c and away from the first air inlet 6, thereby reducing the possibility of air from the external environment entering the first space 2 through the first air inlet 6. In this way, the first air inlet 6 can be arranged open, and there is no need to arrange a top ventilation part 5a at the first air inlet 6, thereby reducing the arrangement cost and control cost of the agricultural building unit 100.

[0131] Secondly, by arranging the flow guide part 5c obliquely to the ground, the flow guide space 20 will be formed between the flow guide part 5c outside the top of the frame 1 and the frame 1, and the flow guide space 20 is above the first space 2, which can receive the hot air rising from the first space 2 and guide the hot air to the first air inlet 6.

[0132] It should be noted that after being heated, the movement of air in the vertical direction is prior to its movement in the horizontal direction, so under the influence of no other factors, the air usually flows upwards after being heated. In this way, the flow guide part 5c connected to the top of the frame 1 can receive the hot air rising from the first space 2 and guide the tendency of the hot air flowing in the vertical direction to flow in the horizontal direction, so that the hot air flows smoothly to the first air inlet 6, avoiding the accumulation of hot air in the first space 2, which affects the dynamic stable air temperature environment of the first space 2 and the third space 8.

[0133] Reference Figure 16In some agricultural building units 100, the number of flow guide portions 5c is multiple. The multiple flow guide portions 5c are arranged in sequence, the second end 5c2 of any flow guide portion 5c extends above the first end 5c1 of the adjacent flow guide portion 5c, and a connecting portion (not shown in the figure) is connected between the second end 5c2 of any flow guide portion 5c and the first end 5c1 of the adjacent flow guide portion 5c. The connecting portion is arranged vertically, and the first air outlet 6 is arranged at the connecting portion. In this way, the multiple flow guide portions 5c can form a windproof structure in cooperation with each other. For example, in the agricultural building unit 100 in which the flow guide portions 5c are arranged towards the north side, the wind from the north side with a height close to the top of the frame 1 will be guided by the first flow guide portion 5c towards the north side, and flow upwards away from the first air outlet 6, so as to avoid the external airflow affecting the air outflow of the first space 2. Even if part of the airflow bypasses the first flow guide portion 5c towards the north side and flows into the second flow guide portion 5c towards the north side, the second flow guide portion 5c towards the north side will still guide the airflow to flow upwards, so as to make the airflow away from the first air outlet 6. In this way, in the agricultural building unit 100 in which the flow guide portions 5c are arranged towards the north side, only the first air outlet 6 at the southernmost side has the possibility of reverse airflow entering, which greatly reduces the influence of the external environment on the first space 2 and the third space 8.

[0134] In some agricultural building units 100, it is not necessary to arrange the side ventilation member 9a on each side. In this type of agricultural building unit 100, it can be considered that the side facing away from the sunlight does not need to be provided with the side ventilation member 9a. For example, the agricultural building unit 100 has at least a sunny side and a shady side arranged oppositely, and the side ventilation member 9a is arranged on at least one side other than the shady side. The sunny side is the main lighting side of the agricultural building unit 100, that is, the side that can receive direct sunlight during the peak sunlight period (10:30 to 15:00), and the other side opposite to the sunny side is the shady side. For example, in the northern hemisphere, the sunny side is usually the southern side or the region close to the southern side, and the shady side is the northern side or the region close to the northern side.

[0135] The other structures of the embodiment 4 are the same as those of the embodiment 2, which will not be described herein again.

[0136] Embodiment 5

[0137] The difference between the embodiment 5 and the embodiment 4 is that, with reference to Figures 18-19 , the first air outlet 6 of the agricultural building unit 100 in the embodiment 5 is arranged obliquely to the ground, and the top wall body 5 includes multiple top light-transmitting films 5d. The multiple top light-transmitting films 5d can be penetrated by sunlight and are movably connected to the first air outlet 6, so that the top light-transmitting films 5d can be opened and closed along the arrangement direction of the first air outlet 6, so as to open and close the first air outlet 6 and form the flow guide surface 21.

[0138] By tilting the first air outlet 6 relative to the ground and arranging the top light-transmitting film 5d at the first air outlet 6, the top of the frame 1 can form a structure for guiding airflow by means of the top light-transmitting film 5d. For example, when the first air outlet 6 is partially open, the top light-transmitting film 5d partially covers the first air outlet 6. At this time, the top light-transmitting film 5d covering the first air outlet 6 is tilted relative to the ground and can guide the hot air rising from the first space 2 to the opening of the first air outlet 6, so that the hot air flows out of the first air outlet 6. Compared with forming the first air outlet 6 by the top ventilation member 5a or keeping the first air outlet 6 open, the top light-transmitting film 5d is movably connected to the first air outlet 6, which can reduce the configuration cost of the first air outlet 6 and provide operable opening and closing control for the first air outlet 6.

[0139] It can be understood that the frame 1 itself has a certain thickness, so even if the top of the frame 1 adopts a flat structure, the first air outlet 6 can still be tilted by using the thickness of the frame 1.

[0140] Reference Figures 18-19 In the agricultural building unit 100 of the present embodiment 5, the top wall 5 at other positions also includes a plurality of top light-transmitting films 5d, which can be penetrated by sunlight and are fixed above the first space 2. In this way, in the agricultural building unit 100 of the present embodiment 5, the top wall 5 is entirely constructed by the top light-transmitting films 5d. It should be noted that by fixing the top light-transmitting films 5d above the first space 2 and covering the top light-transmitting films 5d at the first air outlet 6, the agricultural building unit 100 can allow infrared light and ultraviolet light to enter the interior of the first space 2 during the sunlight period, thereby improving the air temperature reserve of the first space 2. Therefore, the agricultural building unit 100 of the present embodiment 5 is suitable for use in cold regions and can provide a good cold-resistant environment for the agricultural building unit 100.

[0141] Considering that the temperature in cold regions is relatively low, the agricultural building unit 100 can be applied in cold regions, i.e., regions with a weekly average ambient temperature below 0°C. Reference Figure 20 As an example of the present embodiment 5, under the second environmental temperature condition, i.e., when the weekly average ambient temperature is below 0°C, the side wall 9 is configured 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 side wall 9 during the sunlight period, thereby improving the air temperature reserve of the third space 8 and the first space 2.

[0142] As the same as the top wall body 5, the side wall body 9 also has various configurations to adapt to different environments. For example, the side wall body 9 includes a side ventilation piece 9a, which can be opened and closed relative to the support 7 and forms a second air inlet 10 for introducing natural air flow when the side ventilation piece 9a is opened relative to the support 7. It should be noted that the side ventilation piece 9a of the present embodiment 5 is part of the side wall body 9 of the present embodiment 5, so the side ventilation piece 9a of the present embodiment 5 can also be penetrated by sunlight. Alternatively, the side wall body 9 can include a plurality of side ventilation pieces 9a and a plurality of side light-transmitting pieces 9b, which are fixedly connected with the support 7, and at least part of the side light-transmitting pieces 9b are arranged in intervals with part of the side ventilation pieces 9a. It should be noted that the side light-transmitting piece 9b of the present embodiment 5 is also part of the side wall body 9 of the present embodiment 5, so the side light-transmitting piece 9b of the present embodiment 5 can also be penetrated by sunlight. As an example of the present embodiment 5, the side light-transmitting piece 9b can be a plate piece such as a solar panel, etc. having high structural strength.

[0143] In some areas where the windproof requirement is not high, the side wall body 9 can also be assembled by a film. For example, referring to Figure 20 As an example of the present embodiment 5, the side wall body 9 includes a plurality of side light-transmitting films 9c, which can be penetrated by sunlight and are fixedly connected with the support 7.

[0144] Of course, considering the need for opening and closing the second air inlet, the side wall body 9 of this type of agricultural building unit 100 can also be covered with a film at the second air inlet 10, for example, referring to Figure 20 As an example of the present embodiment 5, the side wall body 9 further includes a plurality of side light-transmitting films 9c, which can be penetrated by sunlight and are movably connected to the second air inlet 10 to open and close the second air inlet 10. Compared with the side ventilation piece 9a and the side light-transmitting piece 9b, the side light-transmitting film 9c can reduce the scattering of sunlight, improve the air temperature reserve of the third space 8 and the first space 2, and by opening the side light-transmitting film 9c connected to the second air inlet 10, the agricultural building unit 100 of the present embodiment 5 can also achieve the same ventilation effect as the agricultural building unit 100 of the embodiment 4.

[0145] The other structures of the present embodiment 5 are the same as those of the embodiment 4, which will not be described here.

[0146] In summary, the agricultural building unit 100 provided by the embodiment of the present application is capable of cooperating the frame 1, the support 7, the top wall 5, the side wall 9 and the first barrier 11 to separate the top of the first space 2 and the atmospheric environment by the cooperation of the top wall 5 and the frame 1, to separate the circumferential side of the first space 2 and the atmospheric environment by the cooperation of the side wall 9 and the support 7, and to separate the bottom of the first space 2 and the atmospheric environment by the first barrier 11, so as to make the agricultural building unit 100 of the present application enclose the first space 2 and the third space 8 in the atmospheric environment to form an environment space with a temperature more suitable for agricultural cultivation than the atmospheric environment. In this way, the agricultural building unit 100 of the present application is capable of constructing an agricultural cultivation space with more optimal environment conditions in a harsh environment such as a sandy area, a desert area or a severe cold area, so as to make the agricultural building unit 100 of the present application construct a greenhouse, a breeding farm and an unclosed cultivation field in a harsh environment by taking the first space 2 as a basic environment for agricultural production.

[0147] Secondly, the agricultural building unit 100 is capable of preventing the first space 2 and the third space 8 from being directly irradiated by infrared light and ultraviolet light by configuring the top wall 5 and the side wall 9 to be capable of being penetrated by visible light and at least one of reflecting or absorbing infrared light and ultraviolet light, reducing the heat accumulation of the first space 2 and the third space 8 caused by natural lighting, and effectively inhibiting the secondary radiation of the ground of the external environment to the first space 2 and the third space 8 by separating the first space 2 and the third space 8 from the ground of the external environment by the first barrier 11. Moreover, under the cooperation of the top wall 5 and the side wall 9, the light heat absorbed by the first barrier 11 is lower than that of the ground of the external environment under the direct sunlight, and the temperature of the first barrier 11 is much lower than the ground temperature under the direct sunlight, so as to reduce 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. In this way, the temperature control cost of the greenhouse, the breeding farm and the unclosed cultivation field constructed in the first space 2 can be effectively reduced, and the operation energy consumption of the greenhouse, the breeding farm and the unclosed cultivation field can be saved.

[0148] Secondly, the agricultural building unit 100 is arranged with the vegetation layer 13 on the outer circumferential side of the side wall body 9 through the second partition 12. Under the transpiration of the vegetation layer 13 and the evaporation of water for the vegetation, the area where the vegetation layer 13 is located can form a local air temperature environment with a temperature lower than the ground temperature of the atmospheric environment. In combination with the air temperature environment of the third space 8, the air flow of the atmospheric environment can enter the agricultural building unit 100 from the second air outlet 10 and leave the agricultural building unit 100 through the first air outlet 6, so as to form a natural ventilation air flow from bottom to top in the first space 2 and diffuse the air with a lower temperature near the third space 8 and the first partition 11 to the first space 2 within a certain time of opening the natural ventilation, thereby quickly reducing the environmental temperature of the first space 2. In this way, the temperature control cost of the greenhouse, the breeding field and the non-closed cultivation field constructed in the first space 2 can be effectively reduced, and the operation energy consumption of the greenhouse, the breeding field and the non-closed cultivation field can be saved.

[0149] Secondly, the vegetation layer 13 adjacent to the second air outlet 10 cooperates with the third space 8, so as to form a local low-temperature environment similar to a tree shade area and dynamic stable. The vegetation layer 13 can reduce the wind speed entering the agricultural building unit 100, so that the speed of the hot air of the external environment invading the agricultural building unit 100 is greatly slowed down. Moreover, when the air flow of the external environment passes through the vegetation layer 13, heat exchange can occur between the air flow and the vegetation layer 13, so that the air flow entering the agricultural building unit 100 is pre-cooled by the vegetation layer 13, the temperature of the air flow entering the agricultural building unit 100 is reduced, and the air flow outside the agricultural building unit 100 is prevented from flowing in to excessively affect the air temperature environment of the first space 2.

[0150] Secondly, the support 7 is arranged on the outer circumferential side of the frame 1, and the side wall body 9 is arranged on the support 7. When the agricultural building unit 100 encounters meteorological disasters such as gales and sandstorms, the side ventilation part 9a can be closed to make the side wall body 9 become a flow guide surface 21 inclined to the ground, so as to prevent the first space 2 from being disturbed by meteorological disasters such as gales and sandstorms and ensure the ecological safety of the agricultural production in the agricultural building unit 100.

[0151] The above is only the preferred embodiment of the present application. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and replacements can be made without departing from the technical principles of the present application, and these improvements and replacements should also be regarded as the protection scope of the present application.
