Description
Technical Field
The present invention relates to a greenhouse, and more particularly, to a greenhouse which stores foam concentrate and generates foam to improve thermal insulation and heat preservation.
Background
The greenhouse is a building in which plants can be freely planted by artificially controlling illumination, temperature and humidity. Such a greenhouse can be surrounded by a transparent material such as a synthetic resin film, glass, etc., and transmits sunlight and solar heat, and can maintain a high internal temperature since external air does not flow inside. In a greenhouse, plants can be grown throughout the year, and the harvesting of the plants can also be controlled.
On the other hand, in winter, the outside temperature decreases, and the inside temperature of the greenhouse decreases due to the inside heat loss. In addition, in summer, the interior temperature of the greenhouse is higher than necessary due to strong direct sunlight and high temperature of the exterior temperature. For this, a heating apparatus (e.g., a furnace, a boiler, etc.) or a cooling apparatus (e.g., an air conditioner) is installed in the greenhouse to maintain the interior temperature of the greenhouse at an appropriate level. However, these facilities require a large amount of installation costs and maintenance costs.
In addition, the heat-insulating cover can be applied to a greenhouse. The heat-insulating cover is located on the outer surface of the greenhouse to cover the greenhouse, thereby providing heat-insulating and light-blocking functions for the greenhouse. Such insulation covers can be easily applied to relatively small greenhouses, but are cumbersome to expand and open when applied to relatively large greenhouses. In relatively large greenhouses, separate mechanical devices are installed so that the insulating cover can be opened and folded.
However, the heat-retaining cover is bulky, and therefore cannot be opened even if it is smoothly deployed by a mechanical device, and may not work properly even when it is snowy or rainy.
The greenhouse consists of a double structure and a protective layer may be formed between the structures. The protective layer is filled with air to provide temperature control and thermal effects. It is difficult to achieve temperature control and insulation effects using only air, and thus the protective layer may be filled with foam. Typically, foam concentrate and air are used to create the foam. However, the foam generating apparatus is made of a complicated structure for supplying and recovering the foam liquid.

Hereinafter, embodiments according to the technical idea of the present invention will be described in detail.
Fig. 1 is a perspective view showing a greenhouse 100 according to a preferred embodiment of the present invention, fig. 2 is a perspective view showing a state in which foam is filled in a frame bag portion 103 of the greenhouse 100 shown in fig. 1, fig. 3 is a view showing a state in which a foam generating portion 105 is incorporated in the frame bag portion 103 in the greenhouse shown in fig. 1, fig. 4 is a view of being closed by an opening and closing portion 106 in the greenhouse 100 shown in fig. 1, and fig. 5 is a view showing a state in which the greenhouse 100 shown in fig. 1 is opened by the opening and closing portion 106.
Referring to fig. 1 to 5, a greenhouse 100 according to a preferred embodiment of the present invention includes an inner frame portion 101, an outer frame portion 102, a frame bag portion 103, a bag bracket portion 104, and a foam generation portion 105, and controls the state of the frame bag portion 103 according to the external environment of the greenhouse 100. The foam generating part 105 generates foam inside the frame bag part 103 to fill the frame bag part 103 and control the heat insulation and preservation performance of the greenhouse 100.
The inner frame portion 101 is located on the ground while forming the cultivation space 100 a. The cultivation space 100a is formed in a tunnel shape and accommodates plants. As shown in fig. 1 and 2, the cultivation space 100a is tunnel-shaped, but is not limited thereto, and may be formed in various shapes (for example, dome-shaped) as long as it can accommodate plants. In addition, the inner frame portion 101 is made of a frame.
The outer frame part 102 is located on the ground, spaced apart from the inner frame part 101, outside the inner frame part 101 and corresponds to the inner frame part 101. The outer frame part 102 is made of a frame, similar to the inner frame part 101.
The outer frame portion 102 is covered with a frame cover made of a synthetic resin film or the like, and the frame cover can hold the cultivation space 100a in a closed state. On the other hand, the housing can be folded and unfolded as needed, and can be used to open and close the cultivation space 100 a.
The inner frame part 101 as described above comprises a wall frame part 111 and a roof frame part 113, and the outer frame part 102 comprises a wall frame part 121 and a roof frame part 123. Since the inner frame portion 101 and the outer frame portion 102 have the same structure except for the difference in size and position, the present embodiment is for describing the wall frame portion 111 and the roof frame portion 113 that the inner frame portion 101 has.
The wall frame portions 111 are made of a pair, but are located on the ground along the longitudinal direction of the cultivation space 100 a. The cultivation space 100a is located between the wall frame parts 111.
The roof frame portion 113 connects upper ends of the wall frame portions 111 to each other. The roof frame portion 113 is positioned to close the upper face of the cultivation space 100a, and has an arch shape.
Meanwhile, the wall frame portion 121 and the roof frame portion 123 of the outer frame portion 102 correspond to the wall frame portion 111 and the roof frame portion 113 of the inner frame portion 101, respectively.
The frame pocket 103 is located between the inner frame portion 101 and the outer frame portion 102, and has a closed storage space 103 a. The frame pocket 103 may expand or contract. The frame pocket 103 may have a shape of a pocket made of a synthetic resin film, or may have a shape in which a pair of synthetic resin films are combined.
The foam concentrate is stored in the storage space 103 a. At this time, the foam concentrate occupies the lower portion of the storage space 103 a. The upper portion of the storage space 103a is empty. In addition, a part of a foam generating portion 105 described later is inserted into a lower portion of the storage space 103a to contact the foam liquid. The foam generating portion 105 supplies air to the lower portion of the storage space 103a so that the air comes into contact with the foam concentrate. At this time, foam is generated in the storage space 103a and filled in the upper portion of the storage space 103 a. At this time, the foam is a collection of bubbles, and after a predetermined time has elapsed, the foam sinks or collapses in the upper portion of the storage space 103a, and becomes a foam liquid. Foam concentrate may be introduced into a lower portion of the storage space 103a, and foam may be generated in the storage space 103 a. In this case, the foam concentrate is a solution in which solutes such as soap solution, glycerin, starch syrup, sugar and the like are dissolved in a solvent such as water. When controlling the amount of solutes in the foam concentrate, foam can be generated from the foam concentrate and maintained for at least 1 hour.
For example, when air is supplied to the storage space 103a, the frame bag portion 103 is inflated to be in close contact with the inner frame portion 101 and the outer frame portion 102, and serves to enclose between the inner frame portion 101 and the outer frame portion. Since the foam concentrate is stored in the lower portion of the storage space 103a, the foam concentrate is generated in the form of foam in contact with the air. Therefore, the frame bag part 103 provides the greenhouse 100 with a function as an insulating and heat-preserving layer due to a combination of air supplied to the storage space 103a and foam generated in the storage space 103 a. Further, the frame cover covering the outer frame portion 102 can protect the frame bag portion 103 by blocking wind generated outside the greenhouse 100, and can hold the frame bag portion 103 in a predetermined shape.
On the other hand, when the frame bag portion 103 contracts, the foam sinks or breaks and becomes foam liquid, and is stored in the lower portion of the storage space 103a, and the air is discharged from the upper portion of the storage space 103 a. Thus, the thermal and insulation layers for the greenhouse 100 are reduced.
In addition, the frame pocket 103 includes a wall pocket 131 and a roof pocket 133.
The wall bag portion 131 forms a storage space 103a corresponding to the wall frame portions 111, 121, and the roof bag portion 133 forms a storage space 103a corresponding to the roof frame portions 113, 123. At this time, the wall pocket 131 and the roof pocket 133 are separated from each other, and the upper face of the wall pocket 131 is positioned adjacent to the side of the arched roof pocket 133.
Further, the frame bag portion 103 is provided with a bag opening/closing portion 103 b. The bag opening/closing portion 103b opens and closes the storage space 103a of the frame bag portion 103.
When heat preservation is required, the bag opening/closing portion 103b closes the storage space 103 a. At this time, when air is supplied to the storage space 103a, the frame bag part 103 is expanded by the air, and foam is generated in the storage space 103 a. In addition, the internal pressure of the frame bag portion 103 increases.
When the internal pressure of the frame bag part 103 exceeds a set value due to air and foam, the bag opening and closing part 103b is opened to discharge air to the outside of the frame bag part 103. That is, air is discharged from the storage space 103a of the frame bag 103 through the bag opening/closing part 103 b. At this time, the internal pressure of the frame bag 103 is reduced. In addition, when air is discharged from the storage space 103a of the frame bag 103 and the internal pressure of the frame bag 103 reaches a set value, the bag opening and closing part 103b is closed. On the other hand, when the frame bag part 103 is retracted, the bag opening and closing part 103b is opened to discharge air from the storage space 103a of the frame bag part 103. Accordingly, the bag opening and closing part 103b can control the internal pressure of the frame bag part 103, thereby preventing the frame bag part 103 from being excessively expanded and damaged by air and foam.
At this time, the bag opening/closing portion 103b is in the shape of a thin and flexible vinyl hose, but is closed in a folded state and can be opened in a state released from the folded state. When the internal pressure of the frame bag part 103 exceeds a set value, the bag opening and closing part 103b is opened while being released, and air can be discharged from the storage space 103a through the bag opening and closing part 103 b. In addition, when the internal pressure of the frame bag part 103 reaches a set value, the bag opening and closing part 103b is folded and closed to close the storage space 103 a. At this time, air is not discharged from the storage space 103 a. Since the bag opening and closing portion 103b is made in the shape of a thin and flexible vinyl hose, the opening and closing of the storage space 103a can be realized at low cost.
In addition, in order not to discharge the foam concentrate by the pouch opening/closing part 103b in a state where the frame pouch part 103 stores the foam concentrate, the pouch opening/closing part 103b is preferably provided at the upper end of the wall pouch part 131 and attached to the upper surface of the roof pouch part 133. That is, the bag opening and closing part 103b is installed at the upper part of the wall bag part 131 and the upper part of the roof bag part 133 to discharge air.
The pocket bracket portion 104 supports the frame pocket portion 103 between the inner frame portion 101 and the outer frame portion 102. In addition, the bag bracket part 104 is bent to form a predetermined space, and is positioned in the longitudinal direction of the cultivation space 100 a. At this time, since the frame bag portion 103 is in a state of storing the foam liquid, a portion of the frame bag portion 103 storing the foam liquid can be placed on the bag holder portion 104. Therefore, the frame bag portion 103 can maintain a stable state of storing the foam liquid by the bag holder portion 104. The bag bracket portion 104 includes a wall bag bracket portion 141 and a roof bag bracket portion 143.
The wall bag bracket portion 141 is located on the floor between the wall frame portion 111 of the inner frame portion 101 and the wall frame portion 121 of the outer frame portion 102 for supporting the underside of the wall bag portion 131. The wall bag portion 131 is placed on the wall bag bracket portion 141.
The roof bag bracket portion 143 is supported by the wall frame portion 111 of the inner frame portion 101 and the wall frame portion 121 of the outer frame portion 102 so as to be positioned between the roof frame portion 113 of the inner frame portion 101 and the roof frame portion 123 of the outer frame portion 102. The lower surface of the roof bag 133 is supported by the roof bag bracket 141. The contracted roof bag portion 133 is placed on the roof bag bracket portion 143, and the expanded roof bag portion 133 is placed only on the lower portion of the roof bag support portion 13. That is, the lower portion of the roof bag 133 is held on the roof bag support 143.
The foam generating part 105 is connected to the frame bag part 103, and supplies air to the storage space 103a of the frame bag part 103, generating foam liquid stored in the lower portion of the storage space 103 a. The generated foam fills the upper portion of the storage space 103a, thereby providing heat insulation and warm keeping effects to the greenhouse 100. In addition, the bubble generating part 105 includes a supply pipe part 151, a connection pipe part 152, and an air supply part 153.
The supply tube part 151 is formed in a tube shape and inserted into the storage space 103a of the frame bag part 103. In particular, the supply pipe part 151 is located below the wall bag part 131 and below the roof bag part 133. In addition, the supply pipe portion 151 is immersed in the foam liquid stored in the frame bag portion 103, that is, the foam liquid immersed in the storage space 103 a.
A plurality of supply holes 151a are formed in the outer circumferential surface of the supply pipe part 151. The supply hole 151a connects the inside and the outside of the supply tube part 151. At this time, the supply hole 151a is formed along the longitudinal direction of the cultivation space 100 a.
The supply pipe part 151 may be formed in the shape of a vinyl pipe. Therefore, the supply pipe part 151 is mounted at the frame bag part 103 so as to be easily transportable. In addition, since the supply pipe portion 151 is made of vinyl, it can float on the surface of the foam liquid without being immersed in the foam liquid in the storage space 103 a. At this time, a guide shaft (not shown) may be inserted into the supply tube part 151. Therefore, the supply pipe portion 151 may contact the bottom surface of the storage space 103a and maintain a state of being submerged in the foam liquid.
The connection pipe portion 152 is connected to one end surface of the supply pipe portion 151. At this time, the connecting tube portion 152 is positioned adjacent to the bag holder portion 104. For example, when the supply tube part 151 is inserted into the lower portion of the wall bag part 131, the connection tube part 152 is connected to the supply tube part 151 located at the lower portion of the wall bag part 131 so as to be adjacent to the wall bag bracket part 141. In addition, when the supply tube part 151 is inserted into the lower portion of the roof bag part 133, the connection tube part 152 is connected to the supply tube part 151 positioned at the lower portion of the roof bag part 133 so as to be adjacent to the roof bag bracket part 143.

The air supply part 153 supplies air to the supply pipe part 151 through the connection pipe part 152. At this time, air is supplied to the supply pipe portion 151, passes through the supply hole 151a, and is split and deformed in the shape of foam through the supply hole 151a to be combined with the foam concentrate. Accordingly, foam generation and filling are completed in the storage space 103a of the frame bag part 103.
On the other hand, the foam filled in the upper portion of the storage space 103a is collapsed or broken to become foam liquid, which is guided to the lower portion of the storage space 103a and stored inside the frame bag portion 103 as it is. When the air supply part 153 supplies air to the supply pipe part 151, the foam liquid is again generated as foam by the air, and may be used to fill the upper portion of the storage space 103 a.
The foam generating section 105 of the present embodiment fills the upper portion of the storage space 103a by supplying air to the foam concentrate in the storage space 103a to generate foam. The foam liquid changed from the foam is introduced into the supply pipe portion 151 of the foam generating portion 105, and may be used again for generating the foam. That is, the foam generating portion 105 may be used in combination with the frame bag portion 103 to continuously generate the foam liquid of the storage space 103a in the form of foam.
In the greenhouse 100 of the present embodiment as described above, the frame bag portion 103 stores the foam concentrate in a state of being supported by the bag bracket portion 104. The foam generating part 105 is inserted into the frame bag part 103 to supply air to the storage space 103a of the frame bag part 103. At this time, when the air passes through the supply hole 151a of the supply pipe portion 151 of the foam generating portion 105, the foam liquid is generated as foam. The foam is filled in the upper portion of the storage space 103 a. In addition, in the upper portion of the storage space 103a, the foam is collapsed or broken and becomes a foam liquid to be stored in the lower portion of the storage space 103 a. The foam concentrate can be used again for generating foam. For this reason, the greenhouse 100 of the present embodiment generates foam by being stored in the frame bag part 103 in the form of foam, and after the foam is generated, without supplying or recovering the foam liquid, the foam that is subsided or broken in the storage space 103a of the frame bag part 103 can be used for the foam liquid. That is, the foam concentrate can be continuously used in the storage space 103 a.
The greenhouse 100 of the present embodiment may further include an opening/closing unit 106.
The opening/closing part 106 is connected to the frame bag part 103 such that the frame bag part 103, particularly the upper end part of the wall bag part 131 and the upper end part of the roof bag part 133, moves upward to open the frame bag part 103, and when the cultivation space 100a needs to be kept warm, the cultivation space 100a is kept closed by using the frame bag part 103. The foam generating part 105 generates foam in the frame bag part 103 to fill an upper portion of the storage space 103 a. Accordingly, the frame pocket 103 may provide heat insulation, heat preservation, and light shielding functions to the cultivation space 100 a. The opening/closing unit 106 opens and closes the cultivation space 100a in a state where the lower portions of the wall bag portion 131 and the roof bag portion 133 are fixed.
In addition, the opening and closing part 106 opens the cultivation space 100a, a part of the frame pocket part 103, particularly, an upper end part of the wall pocket part 131, and an upper end part of the roof pocket part 333 are moved downward, so that the frame pocket part 103 is folded. At this time, the foam subsides or comes into contact with the inner surface of the frame bag portion 103 to become foam liquid, and the foam liquid is stored in the storage space 103a of the frame bag portion 103.
The opening/closing unit 106 includes a wall opening/closing unit 161 and a roof opening/closing unit 163.
The wall opening/closing portion 161 is connected to the upper surface of the wall bag portion 131 of the frame bag portion 103.

The roof bag 133 is folded while the roof of the greenhouse 100 is opened, thereby opening the cultivation space 100 a.
In addition, when the roof rope part 163d is wound or unwound on the roof driving part 163b, a part of the roof rope part 163d contacts the roof guide part 163c to rotate the roof guide part 163 c. Therefore, the roof guide unit 163c can minimize friction of the roof cable unit 1613 while maintaining a predetermined length of the roof cable unit 163d between the roof connecting shaft unit 163a and the roof driving unit 163 b.
In addition, when the roof frame portions 113 are formed in an arch shape, the roof connecting shaft portions 163a can be more easily separated from each other along the roof frame portions 113.
As described above, in the greenhouse 100 of the present embodiment, the upper ends of the wall bag portions 131 and the roof bag portions 133 are moved by the opening and closing portion 106 to open and close the cultivation space 100 a. At this time, the foam of the frame bag portion 103 becomes a foam liquid, and is stored in the frame bag portion 103.
In addition, the greenhouse 100 of the present embodiment may further include a foam concentrate introducing part 107.
Foam concentrate introducing part 107 connects wall bag part 131 and roof bag part 133 in frame bag part 103. Typically, foam concentrate intake 107 directs foam concentrate from roof bag 133 to wall bag 131. Meanwhile, when the air supply part 153 supplies air to the supply pipe part 151 through the connection pipe part 152, the foam liquid introduction part 107 introduces foam liquid from the wall bag part 131 to the roof bag part 133. Therefore, even if the foam concentrate is not stored in the storage space 103a of the roof bag 133, foam may be generated. The load due to the foam concentrate stored in the roof bag portion 133 is reduced, so that the wall frame portions 111, 121 can be prevented from being deformed by the foam concentrate.
The foam liquid introducing portion 107 includes a recovery channel portion 171, a sensing pump portion 172, and a sensing channel portion 173.
The recovery duct portion 171 connects the wall bag portion 131 and the roof bag portion 133. The foam concentrate is guided from the roof bag 133 to the wall bag 131 through the recovery duct 171. Accordingly, foam concentrate may not be stored in roof bag 133.
The induction pump section 172 is formed in the shape of an underwater pump, is accommodated in the storage space 103a of the wall bag section 131, and is immersed in the foam liquid.
The sensing pipe portion 173 connects the sensing pump portion 172 and the supply pipe portion 151 received in the roof bag portion 133. The sensing pump section 172 sucks the foam liquid and supplies it to the supply pipe section 151 inserted into the roof bag section 133 through the sensing pipe section 173. At this time, the air supply part 153 supplies air to the supply pipe part 151 received in the roof bag part 133. Therefore, the air generates the foam liquid as foam while passing through the supply holes 151a of the supply pipe portion 151. Foam is generated in the storage space 103a of the roof bag part 133.
On the other hand, when air is not supplied to the supply pipe portion 151 accommodated in the roof bag portion 133, the sensing duct portion 173 is closed. Therefore, in the case where the foaming is not performed, the foam concentrate may not be introduced into the roof bag 133. When air is supplied to the supply pipe portion 151 received in the roof bag portion 133, the recovery pipe portion 171 is closed, and the sensing pipe portion 173 is opened to introduce the foam liquid to the roof bag portion 133 through the sensing pump portion 172.
In particular, in order to open and close the sensing pipe portion 173, a check valve may be installed in the sensing pipe portion 173. As the sensing pipe portion 173 is opened and closed by the check valve, the foam concentrate may not flow back from the roof bag portion 133 to the wall bag portion 131.
As described above, the technical idea of the present invention has been described in detail with reference to the preferred embodiments, but the technical idea of the present invention is not limited to the above embodiments, and various modifications and alterations can be made by those skilled in the art within the scope of the technical idea of the present invention.
