Description

Technology Field

[0001] The present invention relates to a system greenhouse for smart farms to which an automation system is applied, and more specifically, to a system greenhouse for smart farms having a reinforcement and connection structure for a roof top bar, which enables faster and more effective construction and installation of the system greenhouse for smart farms, as well as continuously maintaining a more stable construction state against physical elements such as wind or load, by improving the connection structure between the roof top bar and the roof slope bar of the system greenhouse for smart farms and newly applying a continuous reinforcement connection structure of the roof top bar. Background Technology

[0002] Conventional greenhouses used for crop cultivation typically consist of rectangular structures made of vinyl, glass, or plastic, equipped with simple control devices that rely on manual labor to regulate temperature, humidity, and soil moisture. Furthermore, because these existing greenhouses manage crops in a passive manner, a significant amount of manpower is absolutely required; while such greenhouses can be constructed at a relatively low cost, they have the disadvantage of being difficult to control the environment according to weather conditions.

[0003] Accordingly, recent greenhouses incorporate more advanced technologies. By introducing systematic automation systems based on the latest technology, they measure temperature, humidity, sunlight, and soil moisture according to weather conditions using sensors, and automatically control the interior of the greenhouse through complex environmental control devices. Furthermore, more systematic and efficient crop management is possible through the use of LED lighting to control light sources, supply water, and manage water quality. Although such greenhouses require high initial costs, operating costs tend to decrease and productivity increases as automation progresses.

[0004] In particular, unlike conventional greenhouses, smart farm greenhouses capable of automated complex environmental control using advanced technologies such as LED lighting and CO2 concentration regulation have recently emerged. These smart farm greenhouses can optimize crop growth environments and increase productivity by utilizing various technologies including big data, artificial intelligence, and robotics.

[0005] While the structure of such a smart farm greenhouse is similar to that of a conventional greenhouse, it is equipped with additional equipment such as IoT sensors, control systems, and LED lighting. These devices detect and analyze environmental factors to provide optimal growth conditions for crops, and utilize big data and artificial intelligence technologies to collect and analyze crop growth information, thereby enabling more precise environmental control and crop production.

[0006] Furthermore, smart farm greenhouses are typically operated via remote control using cloud technology, allowing farmers worldwide to monitor and operate the internal conditions of the greenhouse through their smartphones or computers. Since smart farm greenhouses enable real-time monitoring of production volume and quality, they can increase productivity and promote quality improvement; thus, these technologies play a significant role in enhancing agricultural productivity.

[0007] In the case of a greenhouse that enables such a smart farm, it is equipped with supports installed continuously in all directions, and a roof forming an inclined surface is installed by connecting it to the ends of the supports using these supports. The roof is formed by cutting an extruded member to create divided sections with a predetermined spacing, and then attaching or fixing a light-transmitting film or a rigid film of a size corresponding to each divided section space. This allows sufficient and even lighting to be achieved throughout the entire interior of the greenhouse through the light-transmitting film, thereby not only being more beneficial for plant growth but also serving to reduce the consumption of electrical energy sources required to achieve appropriate illumination.

[0008] In particular, a fixing structure for a light-transmitting film or a rigid film as described above has been disclosed in Registered Patent No. 10-1799020. Since the rigid film is fixed by using the first and second binding members and the cover member without using any fastening screws, it can be fixed or separated more quickly and easily, thereby significantly reducing working time, manpower, and related costs. Furthermore, since no holes for screw fastening are drilled in the first and second binding members, the cover member, or the rigid film, the appearance is aesthetically pleasing and durability and marketability are greatly improved. A rigid film fixing device for a greenhouse has been devised and registered.

[0009] However, due to the difficulty of field application, the fixing structure for light-transmitting or rigid films, such as the aforementioned patent, is currently being fixed using fastening screws in actual field operations. Furthermore, as the proportion of work performed at heights in the field is high, there are inherent safety issues such as workers falling. In addition, existing smart farm greenhouse structures utilize traditional past installation structures and methods that have remained effective to this day. These structures are constructed by installing a robust structure using numerous supporting arms connected longitudinally and transversely, including posts, crossbars, and vertical bars, and then covering and fixing a light-transmitting rigid film over the structure to create a greenhouse with excellent lighting. However, such smart farm greenhouse structures are uneconomical as they require a significant amount of time, equipment, and manpower for construction. Moreover, the interconnected parts, fastening parts, and fixing parts retain their vulnerability to natural disasters such as strong winds or heavy snow, leading to problems such as reduced tension and damage caused by leakage.

[0010] In particular, rigid films are materials that undergo significant deformation under tension, and large deformations occur under snow loads or wind loads, causing frequent shape changes depending on changes in load. Structures to which rigid films are applied are designed to withstand external loads such as typhoons, heavy snow, and heavy rain by maintaining overall stiffness through the introduction of a uniform tensile state across the entire roof of the rigid film, which cannot resist compression or bending. Consequently, the tension introduced into the rigid film can lead to stress relaxation over time due to the elongation change characteristics, causing the film to flap in strong winds (floating) or rainwater to accumulate on the film surface (ponding), which can ultimately result in the film breaking.

[0011] In other words, while rigid films offer the advantage of ensuring excellent light transmission, they have poor durability and possess unnecessarily excessive elasticity. Consequently, light transmission deteriorates after a certain period following installation, leading to a decrease in the greenhouse effect and a gradual increase in energy consumption required to maintain indoor temperatures, thus necessitating periodic replacement. Furthermore, because tension is not initially applied uniformly across the entire roof, sagging or drooping occurs over time, resulting in the continuous incurrence of significant time, effort, and cost for periodic inspections and maintenance of the tension.

[0012] Furthermore, the individual fastening parts that connect and secure posts, crossbars, vertical bars, and support arms are susceptible to water leakage due to the on-site construction method using fastening screws. Additionally, continuous exposure to wind, rain, or snow causes the interconnectedness and fastening strength to gradually weaken or be lost, thereby shortening the lifespan of the entire frame constituting the greenhouse structure. Since the scale is expanded without structural improvements to these interconnected parts, the size, length, thickness, and strength of each component inevitably increase excessively. Consequently, the construction of the structure and facilities, including the frame, becomes more difficult and requires significantly more time and money, resulting in the disadvantage of significantly reduced constructability and economic efficiency.

[0013] Accordingly, the applicant of the present invention, regarding a greenhouse frame configured as described in Registered Patent No. 10-2626681, in which horizontal bars and vertical bars are connected longitudinally and transversely to the leading ends of vertical supports arranged at regular intervals, and a roof bar is positioned upward between adjacent vertical bars to connect the vertical bars and the roof bar through a plurality of downwardly inclined roof arms, wherein the lower ends of the roof arms are connected and fixed through a separately provided lower mounting member and an upper connecting bar, and the high-performance fluoropolymer film is fixed by upper and lower elastic members provided on the upper connecting bar, a film fixing member, a finishing cover, and a fixing member coupled to the roof arm, thereby enabling the maintenance of an optimal environment suitable for crop growth by blocking ultraviolet and infrared rays—the inherent characteristics of the high-performance fluoropolymer film—while allowing light to pass through, as well as simplifying the connection structure between the roof arms for forming the roof portion of the greenhouse structure and increasing durability, so that construction convenience and work efficiency can be significantly improved, and the high-performance fluoropolymer film installed over the entire roof We have proposed and registered a greenhouse structure for a smart farm system that incorporates a high-performance fluoropolymer film, which allows for simple and rapid construction of the fluoropolymer film under tight tension, as well as easy maintenance, repair, or replacement of the high-performance fluoropolymer film, thereby enhancing the overall management efficiency of the greenhouse structure and significantly increasing its service life.

[0014] In addition, regarding a greenhouse frame as described in Registered Patent No. 10-2626686, which is composed of horizontal bars and vertical bars connecting the ends of vertical supports arranged at regular intervals in a longitudinal and transverse manner, and in which roof bars are arranged upward between adjacent vertical bars and connected to the vertical bars through multiple downwardly inclined roof arms, the above-mentioned roof arms are firmly connected and fixed to one another by means of a separately provided angle bracket, and the above-mentioned roof bars are extended and connected through intermediate support bars; at the same time, by configuring the structure so that a high-performance fluoropolymer film is firmly fixed in a tensioned state using these roof bars and roof arms, it is possible to maintain an optimal environment suitable for crop growth by blocking ultraviolet and infrared rays—the inherent characteristics of the high-performance fluoropolymer film—while allowing light to pass through; furthermore, by simplifying the connection structure between the roof arms for forming the roof portion of the greenhouse structure and increasing durability, construction convenience and work efficiency can be significantly improved; and the installation of the high-performance fluoropolymer film applied to the entire roof in a taut tensioned state can be achieved simply and quickly. Of course, a greenhouse structure for a smart farm system employing a high-performance fluoropolymer film has been registered, which facilitates easy maintenance, repair, or replacement of the high-performance fluoropolymer film, thereby enhancing the overall management efficiency of the greenhouse structure and significantly increasing its service life.

[0015] Subsequently, as in Registered Patent No. 10-2636016, a ventilation device for a greenhouse structure for a smart farm system has been registered, comprising a greenhouse frame composed of a horizontal bar and a vertical bar connecting the ends of vertical supports arranged at regular intervals in a vertical and horizontal manner, and a roof bar arranged upward between adjacent vertical bars so that the vertical bar and the roof bar are connected through a plurality of downwardly inclined roof arms, wherein a high-performance fluoropolymer film is fixedly formed over the entire upper portion of the greenhouse frame including the vertical bar, roof bar, and roof arm to complete the greenhouse structure, wherein a ventilation section open at regular intervals is formed on the roof of the greenhouse structure, and the ventilation section is configured such that a ventilation frame having a high-performance fluoropolymer film can automatically rotate by a control system to open and close the ventilation section.

[0016] However, in system greenhouses for smart farms like the aforementioned prior example, the interconnected structure between the roof top bar and the roof slope bar—which are frame components constituting the roof—is simple and not robust. As a result, not only is assembly and construction very poor, but the structure is also vulnerable to physical loads such as strong winds or snow, causing play or shaking at the interconnected parts, which acts as a factor that reduces structural stability.

[0017] In particular, in the case of system greenhouses for large-scale smart farms, roof top bars must be repeatedly connected along the length direction during construction. However, the longitudinal connection structure of the roof top bars is typically constructed by simply attaching separate reinforcement members and bolting them together. Consequently, the vulnerability of the interconnections between the roof top bars leads to twisting of the bars due to strong winds, causing damage or deformation to the interconnections. This reduces the overall durability of the system greenhouse and results in leakage or perforations at the connections, leading to a loss of thermal energy inside the greenhouse. Consequently, effective thermal management and control of the system greenhouse are not achieved, making it difficult to operate more efficiently and economically. Prior art literature

[0032] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0033] FIG. 1 is an upper overall perspective view of the overall structure of the system greenhouse of the present invention, FIG. 2 is a lower overall perspective view of the overall structure of the system greenhouse of the present invention, FIG. 3 is a side overall view of the overall structure of the system greenhouse of the present invention, FIG. 4 is an overall perspective view of the roof of the system greenhouse of the present invention, and FIG. 5 is a perspective view of the roof of the system greenhouse of the present invention with the ventilation window separated.

[0034] In a smart farm system greenhouse to which the present invention is applied, such as in a city, vertical supports (100) (100') are erected at regular intervals in the transverse and longitudinal directions from the construction floor according to the scale of the greenhouse to be constructed, and horizontal crossbars (200) (200') and vertical connecting bars (300) (300') are combined on the upper part of these vertical supports (100) (100') to connect the vertical supports (100) (100') in the transverse and longitudinal directions, and the greenhouse frame (F) of the system greenhouse is erected and installed by the mutual combination of these vertical supports (100) (100'), horizontal crossbars (200) (200'), and vertical connecting bars (300) (300').

[0035] A roof (L) having a repeating gable roof shape is formed on the upper part of such a greenhouse frame (F). The roof (L) is provided with a roof bottom bar (500)(500') fixed to the top of the vertical support (100)(100') along the vertical support (100)(100') arranged in a longitudinal direction, and a roof top bar (400)(400') spaced upward along the length direction of the roof bottom bar (500)(500') between the roof bottom bars (500)(500'). The roof top bar (400)(400') and the roof bottom bar (500)(500') are completed by connecting and fixing the roof top bar (400)(400') and the roof bottom bar (500)(500') at an angle to each other through a roof inclined bar (600)(600') arranged at regular intervals along the length direction of the roof (L). It is.

[0036] In addition, a ventilation window (W) is formed in the roof (L) such that its upper end is hinged to the side of the roof top bar (400) (400') and rotates up and down, thereby enabling air circulation inside the greenhouse through the opening and closing of the ventilation window (W). Furthermore, a system greenhouse for a smart farm can be constructed by closely fixing a roof sheet (S) made of a high-performance fluoropolymer film to the entire roof (L) and the ventilation window (W), thereby realizing excellent light transmission and lightweight properties.

[0037] Here, the loop sheet (S) is made of a high-performance fluoropolymer film. Unlike general scattering films, the high-performance fluoropolymer film is a thin film made using a light-scattering technology. It utilizes the phenomenon that occurs during the process of scattering light in a thin film made using fluorine atoms. Since fluorine atoms are very small, they are known to be very effective in scattering light. Therefore, the loop sheet (S) made of this high-performance fluoropolymer film allows for even light transmission to the entire crop and near the roots due to the excellent characteristics of the high-performance fluoropolymer film, making it very effective for crop growth. Furthermore, it possesses excellent durability, with its inherent characteristics remaining unchanged for a long period, which will provide very advantageous functions and effects in terms of greenhouse maintenance and management.

[0038] In the present invention, for a smart farm system greenhouse of this type, the mutual coupling structure of the roof inclined bar (600)(600') with respect to the roof top bar (400)(400') and the longitudinal extension and connection structure of the roof top bar (400)(400') itself are improved.

[0039] Accordingly, the aforementioned roof top bar (400)(400') is configured such that, as illustrated in FIGS. 6 to 10, downwardly inclined pressing wings (401)(401') are formed protruding along the longitudinal direction on both lower sides, an upwardly inclined bolt insertion groove (402) is formed along the longitudinal direction on the bottom surface of the roof top bar (400)(400'), and fastening ribs (403)(403') are formed spaced apart vertically inside the bolt insertion groove (402); the roof inclined bar (600)(600') is configured such that an inclined seating portion (601) is formed on the upper end of the leading edge to accommodate the pressing wings (401)(401') of the roof top bar (400)(400'), and fastening groove portions (602)(602') are formed along the longitudinal direction on both lower sides; A pair of separately provided triangular fixing members (410)(410') that are positioned opposite each other to connect the loop inclined bar (600)(600') to the loop upper bar (400)(400') in a downward inclined manner are formed by forming an inwardly oriented fastening bend (411)(411') along the inclined sides of the upper sides and an inwardly oriented reinforcing bend (412) on the horizontal side of the lower side, and forming through holes (413)(413') on both sides for inserting fastening bolts (414).

[0040] Here, the above-mentioned roof top bar (400)(400') and roof slope bar (600)(600') are made by extruding aluminum or the like, and by forming the leading ends of the roof slope bar (600)(600') together on both sides of the roof top bar (400)(400'), a roof (L) in the shape of a gable roof is formed by the roof slope bar (600)(600') which is joined downwardly sloped from both sides of the roof top bar (400)(400'). In addition, the triangular fixing member (410)(410') is formed by bending a metal plate, and the roof top bar (400)(400') and the roof slope bar (600)(600') are firmly connected to each other by the triangular fixing member (410)(410'), and the downward slope angle of the roof slope bar (600)(600') can be maintained consistently and naturally set by the triangular fixing member (410)(410').

[0041] Accordingly, the pressing wing (401)(401') of the roof upper part (400)(400') is seated on the inclined mounting part (601) of the roof inclined bar (600)(600') which is arranged to be inclined downward from both sides of the roof upper bar (400)(400'), and the fastening bending part (411)(411') formed on a pair of mutually opposing triangular fixing members (410)(410') is inserted into the fastening groove part (602)(602') of the two sides of the roof inclined bar (600)(600') respectively, so that the roof inclined bar (600)(600') has an inclined angle from both sides of the roof upper bar (400)(400') by the inclined angle of the upper side inclined sides of the triangular fixing members (410)(410'), and the mutually opposing triangular fixing members (410)(410') By attaching a fastening nut (415) to a fastening bolt (414) inserted and protruding through a through hole (413)(413'), the angle fixation and connection of the two loop inclined bars (600)(600') are achieved due to the mutual contact direction pressure applied to a pair of triangular fixing brackets (410)(410').

[0042] Additionally, a separately provided bolt shaft (420), which is inserted upward from the lower side of the mutually opposing triangular fixing members (410) (410') through the space between these triangular fixing members (410) (410'), has its tip inserted into a bolt groove (402) formed in the roof upper bar (400) (400'), and the bolt shaft (420) is screw-fastened to the fastening rib (403) (403') within the bolt groove (402), so that due to the upward fastening force of the bolt shaft (420), the bolt head portion (420a) located at the bottom of the bolt shaft (420) presses upward against the reinforcing bent portion (412) of the triangular fixing member (410) (410'), and at the same time, the inclined seating portion (601) of the roof inclined bar (600) (600') by the pressing wing (401) (401') of the roof upper bar (400) (400') As downward pressure is applied, the roof top bar (400)(400'), the roof slope bar (600)(600'), and the triangular fixing bracket (410)(410') can be firmly and integrally fixed.

[0043] Therefore, by using the triangular fixing member (410)(410') and bolt shaft (420) of the split configuration, the roof slope bar (610)(610') can be quickly and firmly joined to each other in a downwardly inclined form on both sides of the roof top bar (400)(400'). The roof top bar (400)(400'), the roof slope bar (610)(610'), and the triangular fixing member (410)(410') continuously exert a gripping force and pressure fixing force while in a mutually joined state, thereby maintaining a more stable fastening state against wind or impact. Furthermore, through the triangular fixing member (410)(410'), the fastening angle of the roof slope bar (600)(600') can be maintained at a constant angle without separate measurement or estimation, thereby further reducing the construction time and improving the convenience of construction of the system greenhouse.

[0044] Here, the extruded roof top bar (400)(400') must have a continuous length along the length direction of the roof (L) of a large-scale greenhouse. Since it must be cut into specific lengths for production, storage, transportation, and handling, roof top bars (400)(400') of a specific length must be continuously connected and installed along the entire length of the roof (L). At this time, if the interconnected parts of the roof top bars (400)(400') are not sturdy, twisting or separation may occur at the interconnected parts, which not only significantly impairs the structural stability of the greenhouse frame (F) but also causes vulnerabilities such as leakage.

[0045] Accordingly, in order to improve the longitudinal connection structure of the roof top bar (400)(400') in the present invention, as shown in FIG. 11, an upper hinge part (404)(404') having a hinge groove (404a)(404a') for hinge-connecting a ventilation window (W) to both upper sides of the roof top bar (400)(400') is formed to protrude outwardly along the longitudinal direction, and a sheet connecting part (405)(405') having a fitting groove (405a)(405a') for inserting the end of the roof sheet (S) is formed to protrude outwardly along the longitudinal direction on the upper side of the two pressing wings (401)(401'), and a hollow part (406) is formed inside along the longitudinal direction in the middle part of the roof top bar (400)(400').

[0046] The loop top bars (400)(400') created in this way can be quickly and securely connected and fixed through a separately provided connecting block (430) and connecting pad (440)(440') as illustrated in FIGS. 12 to 14. First, a separately provided connecting block (430) having a cross-section identical to the cross-sectional shape of the hollow portion (406) is inserted into the mutually opposing hollow portion (406) of a pair of loop top bars (400)(400') to be continuously connected along the length direction of the loop (L), with a portion of half the total length. Then, a separately provided connecting pad (440)(440'), having a plurality of fastening holes (441)(441') formed through it, is pressed against both sides of the mutual contact portions at the ends of the pair of loop top bars (400)(400') to be connected, and through the fastening holes (441)(441'), the loop top bars (400)(400') and The connection is configured such that a connection nut (451)(451') is screwed onto a separately provided connection bolt (450)(450') that protrudes through the connection block (430), thereby securing the connection in the longitudinal direction to a pair of loop top bars (400)(400').

[0047] At this time, a leading edge portion (442) is formed outwardly protruding from the leading edge of the connecting pad (440)(440') so as to be in close contact with the lower part of the upper hinge portion (404)(404') formed on the loop upper bar (400)(400'), and a lower edge portion (443) is formed outwardly protruding from the lower edge of the connecting pad (440)(440') so as to be in close contact with the sheet coupling portion (405)(405') formed on the loop upper bar (400)(400').

[0048] Accordingly, the connecting block (430), which is tightly inserted into the hollow portion (406) of the roof top bars (400) (400') to be connected to each other, serves to firmly connect the interior of the roof top bars (400) (400'), and the connecting pad (440) (400'), which is in close contact with the outer surface of the mutual connection portion of the roof top bars (400) (400') to be connected to each other, has its leading portion (442) in close contact with the lower part of the upper hinge portion (404) (404') of the roof top bars (400) (400'), and at the same time, its lower portion (443) of the connecting pad (440) (440') is in close contact with the seat coupling portion (405) (405') of the roof top bars (400) (400'), thereby firmly fixing the outer surface of these roof top bars (400) (400'). Therefore, the loop top bars (400)(400') intended to be connected to each other will eventually have strong adhesive fixing force on both the inner and outer sides simultaneously.

[0049] Accordingly, the system greenhouse for smart farms according to the present invention can fasten the roof slope bars (600)(600') that are connected to the roof top bars (400)(400') at an inclined angle on both sides more quickly and securely, and the roof slope angle in the shape of a gable roof formed by the roof slope bars (600)(600') can be fastened and maintained consistently. Additionally, the roof top bars (400)(400') that are continuously connected and constructed along the length direction of the roof (L) can be connected and assembled more strongly and securely by means of a connecting block (430) inserted into the inner side of the mutual end portions of the roof top bars (600)(600') to be connected to each other, and a connecting pad (440)(440') that is in close contact with the outer surface of the mutual end portions, thereby greatly improving the construction convenience and durability of the entire frame of the system greenhouse.
