Description

Ventilation system for greenhouses {Ventilation system for prefab green-house}

The present invention relates to a ventilation system of the greenhouse, and more particularly, to secure the ventilation of the greenhouse by arranging the fixed panel and the flexural panel alternately on the ceiling or sidewall of the greenhouse and automatically flexing the flexural panel as needed. To a ventilation system of a greenhouse that performs ventilation.

In general, in order to intensively produce crops such as vegetables, flowers or fruit trees, greenhouses such as large greenhouses or glass greenhouses are installed and operated. By the way, crops such as vegetables and flowers require proper temperature and mining due to their growth characteristics. Ventilation for maintaining proper indoor temperature while ensuring proper mining in the installation operation of a greenhouse is the best. It is important. For example, shading to maintain the proper temperature in the room during the high temperature period will result in a bad light, which adversely affects the growth of crops. On the contrary, in order to secure sufficient light, it will be difficult to maintain the proper temperature in the room, which will also affect crop growth. do. Therefore, the method of providing the window to a greenhouse, ventilating a greenhouse as needed, ensuring the light required for the growth of a crop, and maintaining the temperature of the room is common.

However, most of the windows of a conventional greenhouse adopt a typical hinge system in which the other end is rotated and closed about its one end, so that the opening ratio of the window in the structural characteristics (for the support of the greenhouse by the wind when the window is opened) is reduced. It is difficult to exceed 12-20% of the total surface area, thereby making it impossible to maintain the room at the required temperature. In other words, the optimum temperature required for the growth conditions of the crop is slightly different depending on the type of crop to be grown, but about 25 ~ 30 ℃ is appropriate, the indoor temperature of the greenhouse during the high temperature temperature is about 70 ~ 80 ℃ when sealed However, even if the window is opened completely, the area is too narrow, so the flow of internal and external air is not made smoothly and reaches about 40 to 50 ° C. Therefore, it is impossible to cultivate crops.

Therefore, conventionally, the indoor temperature of the greenhouse is forcibly lowered by using spraying water, a fan, or an air conditioner during a high temperature period, which requires a huge cost, which is a great economic burden for farmers, but it is difficult to be effective in a large greenhouse. There was.

In addition, in order to reduce heat loss to the outside during the low temperature period, the greenhouses are constructed by double or triple installation of vinyl, etc. The installation and maintenance of the greenhouse is quite complicated, and enormous costs are required for crop cultivation. This will further stimulate excessive temperature rise. The above problems also apply to other structures that require a large amount of indoor ventilation, such as factories or various barns.

The present invention has been made in view of the above-described problems of the conventional greenhouse, the greenhouse is able to withstand the wind even at the opening of the window, while significantly increasing the opening ratio of the room temperature without a separate cooling means in the high temperature crop or breeding livestock The purpose of the present invention is to provide a ventilation system of a greenhouse that can naturally and naturally ventilate the inside and outside to maintain a suitable growth conditions.

On the other hand, it is preferable that the flexural panel 60 is installed alternately with the fixed panel 10 provided on the side wall of the greenhouse.

The drive means can simply be configured as a hydraulic or pneumatic actuator.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

1 is a schematic perspective view of a greenhouse to which the ventilation system according to the present invention is applied, and FIG. 2 is a cross-sectional view of FIG. 1. As can be seen in these figures, the ventilation system of the present greenhouse is constructed by alternately arranging a plurality of flexural panels 60 and fixed panels 10 on the framework 110 of the greenhouse, which is configured as a greenhouse. It is applied only to the ceiling of 100, or it is employ | adopted to both a ceiling and a side wall as needed.

As shown in FIGS. 3A and 3B, the flexural panel 60 has a square inner frame 20 having a space 25 in the center, and a lattice in the space 25 of the inner frame 20. A plurality of crossbars 30 arranged on top, the cover 40 fixed to both sides of the inner frame 20 to seal the space portion 25 to form an air layer, and the edge portion of the cover 40 It is composed of an outer frame 50 coupled to the outer surface of the inner frame 20 to give. The flexural panel 60 has the same configuration as the fixed panel 60, but, as will be described in detail below, the flexural panel 60 is divided into upper and lower panels 61 and 62 so that only one side can be flexed about the other side with respect to the folded part. It is different from this fixed panel 10. Detailed description of the fixing panel 10 will be omitted below.

The inner frame 20 is constituted by assembling or welding each other up, down, left, and right bars formed of hollow rectangular bars. In each bar, the hollow part 21 is divided into the inner and outer hollow parts 22 and 23 by the baffle 24 arrange | positioned in the longitudinal direction. A plurality of coupling slits 26 for coupling the crossbars 30 are formed on the inner surface of the inner hollow part 22 at regular intervals, and fixed slits for fixing the cover 40 on the outer surface of the outer hollow part 23. (27) is formed in the longitudinal direction. The coupling slit 26 is a continuous first slit 26a formed along the longitudinal direction of each bar and a second slit 26b formed to be orthogonal to and spaced along the first slit 26a. This is because the crossbar 30 is formed crosswise (+) as described below. Therefore, the shape of the coupling slit 26 may be appropriately changed according to the shape of the crossbar 30.

On the other hand, the fixed slit 27 is for fixing the edge portion of the cover 40 by the wedge bar 43 when the cover 40 is made of a soft material, such as vinyl sheet 41, At its inner edge, elastic pieces 28 are formed to protrude in contact with the contact surface of the wedge bar 43.

The crossbar 30 is intended to stably maintain the shape of the fixed panel 10 and to support the cover 40. The crossbar 30 may have any shape as long as it can exert a desired function, but preferably has a cross-shaped cross section. Have A plurality of such crossbars 30 are provided to be combined to be orthogonal to each other to form a lattice in the space 25 of the inner frame 20. Thus, two adjacent ribs 31 and 32 are formed longer than the other two ribs 33 and 34 by their thickness, and any one of the ribs 31 and two adjacent ones formed relatively long is formed. Ribs 32, 34 are formed with a plurality of assembly slits 35, 36, 37 at regular intervals for coupling with other cross bars 30 that are perpendicular to each other. This is because the crossbars 30 are formed crosswise to match the upper and lower ends of each crossbar 30 when assembled. Accordingly, the first slit 26a of the coupling slit 26 of the inner frame 20 has a width corresponding to at least twice the thickness of the ribs 31 to 34 of the crossbar 30.

In this case, only one rib 31 of the crossbar 30 may be formed relatively long, but the inner frame 20 is increased in length to fit the coupling slit 26 of the inner frame 20 to realize a more stable assembly state. The rib 32 fitted to the engaging slit 26 of 20 is formed to be long together.

The cover 40 may be used in various ways. In the case of a greenhouse, since appropriate lighting is required, the cover 40 is made of a soft transparent sheet such as a vinyl sheet 41 or a transparent body such as a glass plate 42. For example, when the vinyl sheet 41 is formed, the edge portion of the vinyl sheet 41 is fitted into the fixing slit 27 of the inner frame 20 by the wedge bar 43 to fix the air layer to the space 25 of the inner frame 20. Bar is formed, it is preferable that the vinyl sheet 41 is configured in a cylindrical shape so that the inner frame 20 can be inserted for convenience of production.

Like the inner frame 20, the outer frame 50 is formed by assembling pieces of four bars up, down, left and right in a rectangular frame shape, and each bar has a substantially c-shaped cross section opened inward. Accordingly, a continuous coupling channel 51 for inserting the inner frame 20 is formed on the inner circumference of the outer frame 50. Preferably, the inlet of the coupling channel 51, that is, the inner end of the outer frame 50 is formed so that the engaging jaw 52 elastically caught on the inner end of the inner frame 20 to face each other. In addition, rainwater for preventing rainwater from entering the interior of the greenhouse at both edges of the outer surface of the outer frame 50, that is, at both edges in a direction in which the plurality of panels 1 are continuously disposed during the construction of the greenhouse. Inflow preventing jaws 53 are formed.

Such inner and outer frames 20 and 50 and the crossbar 30 are preferably made of a hard metal such as aluminum or a high strength synthetic resin material.

Each fixed panel 10 of this configuration, for example, is fastened and fixed to the frame 110 through the C-shaped steel 130 at a predetermined interval, the flexural panel 60 is described later between the respective fixed panel (10) The movable support means 70 is installed to be extensible with respect to the frame 110. In this case, the cover flanges 65 of the flexural panel 60 cover the outer edges of the adjacent fixing panels 10, and each cover flange 65 has a packing 67 in close contact with the fixing panel 10. Of course, the rainwater inflow prevention jaw 53 is provided on the outer side of the fixing panel 10 to the inside of the packing 67, so that the inflow of the rainwater into the gap between the panels 10 and 60 when the sealing is closed. Will be prevented.

Accordingly, the greenhouse 100 according to the present invention has an opening ratio close to at least 50%, and the opening ratio of the greenhouse 100 is relatively decreased by relatively decreasing the width of the fixed panel 10 and the expansion panel 60 within a given standard. Up to 85% increase is possible. That is, in the ventilation system of the greenhouse according to the present invention, the fixed panel 10 and the flexural panel 60 are alternately arranged. For example, as shown in FIG. 4A, the width L of the fixed panel 10 and When the width L1 of the flexural panel 60 is configured to be the same, it has an opening ratio of approximately 50%, and the width L1 'of the flexural panel 60 is the width of the fixed panel 10 as shown in FIG. 4B. When the width L1 &quot; of the flexural panel 60 is configured to be 4 times the width L ″ of the fixed panel 10, as shown in FIG. 4C, the aperture ratio of the greenhouse 100 This will increase gradually.

Here, the increasing width of the expansion panel 60 is increased corresponding to the decreasing width of the fixed panel 10, the width (L1, L1 ', L ") of the expansion panel 60 is preferably set within about 2m. This is because, when the width L1, L1 ′, L ″ of the flexural panel 60 exceeds 2 m, the strength of the greenhouse 100 to withstand strong winds during opening of the flexural panel 60 is significantly reduced. This is to achieve structural stability of 100). Therefore, in order to increase the opening ratio of the greenhouse 100, it is more preferable to appropriately set the widths L1, L1 ', L ″ of the expansion panel 60 within the above-mentioned range, and increase the number thereof.

In addition, in the ventilation system of the greenhouse according to the present invention, the opening of the window is divided into two parts by the upper panel 61 of the flexing panel 60, the upper side is exposed to the front side, and the lower side is the side by the flexing panel 60. As it is exposed, the flow rate of the internal and external air is very smoothly and quickly as well as the high opening ratio. That is, as shown in Figure 1, the high-temperature bet is quickly exited to the outside through the upper front exposure portion and at the same time the low-temperature outdoor air is quickly introduced into the interior of the greenhouse 100 through the lower side exposure portion, such airflow The flow of the greenhouse 100 will be made at almost the same time at the same time to maximize the ventilation rate. Therefore, it is possible to maintain the internal temperature of the greenhouse 100 at a temperature suitable for the growth of the crops without a separate cooling means at a high temperature, while also ensuring proper lighting.

On the other hand, Figure 5 to Figure 7 shows an example of the movable support means 70 for operating the flexural panel 60 in the ventilation system of the greenhouse according to the present invention. The movable support means 70 includes a hinge means for rotatably supporting the lower end of the flexion panel 60, a guide means for guiding the flexing action of the flexion panel 60, and the flexion panel 60 as necessary. It consists of a driving means for stretching.

The hinge means is provided with hinge pins 71 on both sides of the lower end of the lower panel 62 of the flexion panel 60, and hinge blocks 72 are respectively installed on the frame 110 of the structure 100 so as to face them. It is composed. Hinge pin 71 is preferably installed on the inner surface of the lower panel 62 so that the flexural panel 60 can be located on the same plane as the fixed panel 10.

The guide means may be provided at both sides of the flexural panel 60, respectively, spaced apart from the two guide rails 73, and at both ends of the upper panel 61 of the flexural panel 60. Consisting of two guides 77 movably coupled to 73. The guide rails 73 are respectively installed in the frame 110 of the structure 100, and are arranged side by side to form two rail pipes 75 and both ends thereof 110 to form a rail slit 76 therebetween. It consists of two fixing blocks (74) fixedly supported. Here, on either side of the two rail pipes 75, when the expansion panel 60 is extended, the seating jaw 75a on which the guide 77 is seated is formed, which is the bending panel 60 when the window is closed. ) Is to be closed securely and reliably.

The guide 77 has a connecting piece 79 protruding inward, and a bracket 78 fixed to the inner side of the upper panel 61 and one end rotatably coupled to an end of the connecting piece 79 of the bracket 78. The guide pin 80 is supported and the other end passes through the rail slit 76 of the guide rail 73. The connecting piece 79 of the guide 77 is preferably formed to be inclined upwardly inwardly as shown for smooth stretching of the flexural panel 60. On the other hand, although not shown separately, the guide means may be configured to have a guide rail has a channel, and further comprising a roller coupled to the channel of the guide rail in the guide pin.

The drive means has a rotating shaft 81 having a pinion 82, a rack 84 meshed with the pinion 82, and one end of which is hinged near a fold of the flexion panel 60, and rotates on the rotating shaft 81. A motor 88 for driving the guide holder 86 and the rotating shaft 81 to guide the movement of the rack 84 while maintaining the engagement between the rack 84 and the pinion 82 as possible, in a forward and reverse direction. Is made of. The rotating shaft 81 is disposed in the width direction of the expansion panel 60 and is supported by the frame 110 or two adjacent fixing panels 10 through the bearing block 83, one end of which is integral to the motor 88. Is connected.

The rack 84 is rotatably connected at one end to a hinge bracket 85 installed near the fold of the flexion panel 60, for example, in the middle of the upper end of the inner surface of the lower panel 62. The guide holder 86 may be configured in various forms. For example, the guide holder 86 may be substantially U-shaped, as shown, and rotatably coupled to the rotation shaft 81 so that both ends thereof surround both sides of the pinion 82. It is supported, and one side has a guide roller 87 in rolling contact with the other side of the rack (84). Here, the pinion 82 may be integrally rotatably mounted to the guide holder 86, and the pinion 82 may be fixedly coupled to the rotation shaft 81 with a key (not shown) or the like.

Although the driving means of such a configuration is not shown separately, it can of course be configured as an actuator such as a hydraulic or pneumatic cylinder.

Hereinafter, an operation of opening and closing the expansion panel 60 of the greenhouse 100 by the movable support means 70 will be described with reference to FIGS. 8A and 8B.

First, FIG. 7 is a state in which the expanding panel 60 is stretched, and the greenhouse 100 is completely sealed. At this time, the upper end of the expansion panel 60, that is, the upper end of the upper panel 61, as shown in Figure 2, as well as entering the inside of the ridge 120 or the like, as well as the upper panel of the expansion panel 60 The guide pin 80 installed in the 61 enters the seating jaw 75a formed on the rail pipe 75 of the guide rail 73 and is tightly sealed so that rainwater does not flow into the greenhouse 100.

In this state, when the greenhouse 100 is to be ventilated, an operating device (not shown) is operated to drive the motor 88 in the forward direction. Then, as shown in FIG. 8A, the pinion 82 mounted on the rotation shaft 81 is rotated in the direction of arrow F, which is clockwise in the drawing, and the rack 84 engaged with the pinion 82 is a structure in the direction of arrow G. As shown in FIG. Is moved outward. Accordingly, one end of the rack 84 fixed to the upper end of the lower panel 62 pushes the upper side of the lower panel 62 outward so that the upper panel 61 and the lower panel 62 of the flex panel 60 are outward. Is folded around the hinge 63. That is, as shown in the drawing, the lower panel 62 of the flexion panel 60 of the upper panel 61, the lower end of which is constrained by the hinge pins 71, etc., and hinges 63 are connected. Since the upper end portion is moved downward along the guide rail 73 by the guide 77 provided therein, the upper panel 61 and the lower panel 62 are folded around the hinge 63.

At this time, the lower panel 62 is rotated in the H direction counterclockwise in the drawing around the hinge pin (71), the rack 84 is rotatably coupled to the rotation shaft 81 so that the pinion 82 is coaxial The engaged state with the pinion 82 is moved without being separated by the coupled guide holder 86. The guide roller 87 of the guide holder 86 guides the rear surface of the rack 84 not engaged with the pinion 82.

FIG. 8B illustrates a state in which the guide 77 reaches the lower end of the guide rail 73 so that the expansion panel 60 is completely opened. As described above, through the open opening, the inflow and outflow of the inside and outside air is made very smoothly to ventilate the interior of the greenhouse 100.

Ventilation of the greenhouse 100 will be described in detail with reference to FIGS. 1 and 2. When the flexing panel 60 is opened, the hot air occupying the upper layer in the greenhouse 100 is quickly discharged as a dotted arrow through the front exposure part that the flexing panel 60 is folded and directly exposed to the outside. At the same time, through the side exposed portion formed on the side of the flexural panel 60, the cold air outside the hot air is quickly discharged into the greenhouse 100, as shown by the solid arrow, into the empty space where hot air is discharged from the inside of the greenhouse. Inflow. Therefore, the hot air discharged and the cold air flowing in naturally form an air flow path, so that the inside and outside air is smoothly ventilated.

On the other hand, when the greenhouse 100 is to be sealed, if the motor 88 is driven in the reverse direction through the operation device, the opening operation proceeds in the reverse order of the above-described opening operation so that the bending panel 60 is unfolded as shown in FIG. 15. As a result, the greenhouse 100 is sealed by closing all the opened portions.

And, in the above-described and illustrated embodiment has been described that can be achieved by opening the expansion panel 60 installed on the ceiling of the greenhouse 100 to achieve a good ventilation of the outside and the outside air, this expansion panel 60 is a greenhouse ( It is installed on the side wall of 100, it is a matter of course that can achieve the same purpose and effect as described above.

Meanwhile, the operation of the expansion panel 60 may be independently performed by providing a dedicated motor 88 for each expansion panel 60. As illustrated in FIG. 9, one rotation shaft 81 ′ may be performed. ) Is configured to be long to cover the plurality of flexural panels 60 to be supported by the bearing blocks 83 and to mount the pinion 82 at a predetermined interval so as to correspond to each flexural panel 60. The plurality of flexural panels 60 may be opened and closed at the same time. In this case, when the greenhouse 100 is small, all the flexing panels 60 located on the same surface may be driven by one motor 88. However, when the greenhouse 100 is small, the flexing panels 60 may be divided into several groups. It is preferable to drive separately by tying in iii).

In the above-described and illustrated embodiments, only the example in which the present invention is applied to the greenhouse has been described. However, the present invention is merely an example, and the present invention is not limited thereto. For example, barn, barn, barn, pig house, etc. Of course, it can be applied to similar structures that require indoor ventilation such as various barns, factories and storage of goods.

As described above, according to the present invention, the greenhouse can withstand the strong wind even when the window is opened, the opening ratio is greatly increased, and the inflow and outflow of the inside and the outside air through the window is made very smoothly and quickly. In a high temperature period, a ventilation system of a greenhouse is provided, which can maintain an indoor temperature appropriately to a growing condition of a crop even by natural ventilation without a separate cooling means as in the prior art.
