Description

Thermal insulation and shading device using bubbles {Apparatus for insualting and shading using bubbles}

The present invention relates to a thermal insulation and sun shade device using a bubble, and more particularly to a device using a bubble as a heat insulating material in a sealed space of the structure to keep the interior of the structure according to the temperature of the outside air and the intensity of sunlight or to use as a sun shade. It is about.

In general, it is desirable to maintain a constant temperature that affects the growth process of the crop depending on the type of crop in the greenhouse. In addition, the transparent window must be formed because the transmission of sunlight essential for the growth of the crop is necessary.

To this end, a method of using a thermal insulation cover of a greenhouse has been widely used. In order to minimize temperature fluctuations due to temperature fluctuations between day and night, a thermal insulation cover was used to cover the greenhouse for keeping warm at night and for shading during the day. As the heat insulating cover, a black shading sheet is mainly used.

However, in order to use the shading sheet in a relatively large greenhouse, a mechanical device for covering the shading sheet covering the upper part of the greenhouse is required.

Such a mechanism basically includes a motor installed in a longitudinal direction on one side of the greenhouse, and a motor for forward and reverse rotation of the shaft, and a thermal insulation sheet wound or unwound on the shaft according to the rotation of the shaft.

But. Such a thermostat will shorten its life due to deformation of the shaft if used over a long period of time. In addition, there is a problem that the thermal effect is poor.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a thermal insulation and sun shade device using a bubble using the bubble as a heat insulating film or a light shielding film.

These plastic sheets 3, 4 are preferably arranged at approximately predetermined intervals, for example 5-50 cm apart from each other. The front and back of the greenhouse may be covered with another plastic sheet or the like to seal the double membrane 10.

Instead of the plastic sheet, a rigid transparent medium such as glass may be used.

A predetermined space (hereinafter referred to as a thermal insulation space) 5 is formed between the plastic sheets 3 and 4. A bubble generator 20 is disposed inside the greenhouse to generate and supply bubbles to the insulating space 5.

2 is a configuration diagram showing an example of the bubble generator 20.

2, the duct 22 is connected to the outlet of the blower 21 through which air of a predetermined pressure is discharged. In the duct 22, a screen 22 having a mesh of a predetermined size is disposed, and a spray nozzle 24 is disposed between the outlet of the blower 21 and the screen 23. One end of the spray nozzle 24 is arranged to be sprayed toward the screen 23, and the other end is connected to the bubble solution reservoir 30 through a pipe 36. In the middle of the pipe 36, a pump 32 for discharging the bubble solution D from the reservoir 30 at a predetermined pressure is connected.

It is preferable that a motor (not shown) for driving the fan 21a of the blower 21 is capable of controlling the air volume by controlling the speed thereof, and the pump 32 is also preferably adjustable in pressure.

Meanwhile, a U-shaped duct 22a bent in a U-shape is formed in the duct 22, and a drain line 25 is connected to a lower portion of the U-shaped duct 22a to accumulate bubbles containing a large amount of water. It is preferred that it be converted to a solution and recovered to the bubble solution reservoir 30. The drain line 25 may be connected to the bubble solution recovery tank 31.

3 is a view showing the layout of the duct of FIG.

Referring to FIG. 3, the duct 22 connected to the blower 21 is provided with branch pipes 26 so as to be connected to both sides of the thermal insulation space 5, respectively. Each duct on the outlet side of the branch pipe 26 is connected to both thermal insulation spaces 5 formed by the double membrane 10, respectively. In addition, on / off valves 27 and 28 are installed in the duct between the branch pipe 26 and the heat insulating space 5, respectively, to selectively generate bubbles generated from the bubble generator 20 into the heat insulating space 5 of the corresponding side wall. Make it available.

Meanwhile, a three-way valve may be provided instead of the branch pipe 26, and the outlets of the three-way valves may be connected to the double membranes 10 of the greenhouses, respectively.

The U-shaped duct 22a may be disposed between the screen 23 and the branch pipe 26, and may be installed between the branch pipe 26 and the thermal insulation space 5, respectively.

The bubble generator 20 may also be used to directly discharge a bubble with a pump, a nozzle and a screen, such as a firefighting apparatus commonly known as a foam generator (foam generator).

On the other hand, in order to generate bubbles, a predetermined pressure is applied to the bubble solution droplets injected to the screen 23 to form bubbles while the air expands the bubble droplets. The bubble formed in this way can be adjusted according to the mesh size of the screen 22 and the pressure of the blower 21, preferably, the bubble generation of 0.5 ~ 2 cm diameter is preferable.

The operation of the greenhouse having the above structure will be described in detail with reference to the drawings.

First, a process of filling one side of the double layer 10 with bubbles will be described with reference to the drawings. The valve 27 of the duct connected to one double membrane 10 is opened, and the valve 28 of the duct connected to the other double membrane 10 is closed. Subsequently, the pump 32 is operated to supply the bubble solution D of the reservoir 30 to the spray nozzle 24. The bubble solution D supplied to the spray nozzle 24 is sprayed to wet the screen 23 on the front surface. At this time, when the blower 21 is operated to blow air of a predetermined pressure to the screen 23, the air expands the bubble solution D between the meshes of the screen 23 into the air, and the air is blown by the air. Discharges bubbles about 1 cm in diameter. The bubbles thus discharged are filled by the surplus air from the blower 24 to fill one surface of the double membrane 10. In about 2 to 4 minutes, the insulating space 5 on one side of the double membrane 10 is filled with bubbles (see FIG. 4).

Subsequently, in order to fill the heat insulating space 5 of the other double membrane 10 with a bubble, the valve 27 facing the one double membrane is closed and the valve 28 facing the other double membrane can be opened and filled in the above manner. . When the heat insulating space 5 in the other double membrane 10 is filled with bubbles, the pump 32 and the air fan 24 are stopped.

On the other hand, the generated bubbles are evaporated after a time elapsed, approximately 3 to 4 hours, and converted into a liquid, and then recovered to the bubble solution recovery tank 31 along the second sheet 4, and the storage tank 30 through the pipe 39. Is recovered and reused. Therefore, if the bubble generation process is repeated before the bubbles disappear, it is possible to have a thermal insulation system using the bubbles for a desired time.

On the other hand, if the size of the bubble is too large when the bubble generator 40 and the blower 21 are easily broken, the air volume is increased by increasing the speed of the fan 21a of the blower 21 and the bubble solution from the pump 32 is increased. The feed amount is increased to form a bubble size to a predetermined size. On the contrary, when the air volume is less than that of the bubble solution, the mobility of the bubble decreases, and an increase in the weight of the bubble may cause a problem that an excessive load is applied to the frames 1 and 2 and the sheets 3 and 4. In this case, the bubble solution supply amount may be reduced to adjust the bubble size to a predetermined size.

On the other hand, the bubble containing a lot of moisture is deposited in the U-shaped duct (22a) while being converted into a bubble solution is recovered to the bubble solution reservoir 30 via the drain line (25).

As described above, the bubbles formed in the double layer 10 not only keep warm in winter, but also act as a bubble shade to serve as a sun shade during the day so that crops in the greenhouse do not die due to strong sunlight in summer. You can also do

In the above embodiment, the plastic sheets 3 and 4 are attached to the two frames 1 and 2 to form the thermal insulation space 5, but the present invention is not limited thereto. That is, only one frame 2 may be provided, and a double plastic sheet may be disposed on the upper portion of the frame 2, and a bubble may be arranged to blow bubbles from the bubble generator 20 between the double plastic sheets.

FIG. 5 is a schematic view of a greenhouse including a thermal insulation and sunlight shade device using bubbles according to a second embodiment of the present invention. The same reference numerals are used for the same components as those in the first embodiment, and detailed descriptions thereof are omitted. do.

Referring to FIG. 5, the greenhouse has a blower 121 for supplying air at a predetermined pressure, a compression container 122 for receiving compressed air from the blower 121, and a compression container 122 connected to both sides. The duct 126 is provided so that the branch pipe 124 which supplies compressed air and the compressed air from the branch pipe 124 may be respectively connected to the pipe 123 provided in the bubble solution collection tank 31 on both sides. Each duct 126 on the outlet side of the branch pipe 124 is connected to the pipe 123 of the corresponding bubble solution recovery tank 31, respectively. In addition, open / close valves 127 and 128 are provided between the branch pipes 126 and the ducts 126, respectively, to selectively supply air from the blower 121 to the corresponding pipes 123.

In addition, a leak valve 129 is disposed at one side of the compression container 122 so that when a large amount of air is supplied from the blower 121, a predetermined amount of air can be discharged to the atmosphere. On the other hand, it is preferable that the motor (not shown) for driving the fan of the blower 121 to control the air volume by controlling the speed.

Both ends of the bubble generating pipe 123 installed in the bubble solution recovery tank 31 are sealed, and a plurality of holes 123a are formed in the circumference thereof, preferably, the upper surface thereof. These holes preferably have a diameter of 1-4 mm and are arranged at regular intervals, for example at 2 cm intervals.

On the other hand, it is preferable to install a level control device to adjust the level of the bubble solution (D) in the bubble solution recovery tank (31). For example, by connecting a pump (not shown) to a container (not shown) in which the bubble solution is stored, and connecting the bubble solution recovery tank 31 to supply the bubble solution to the bubble solution recovery tank 31 as necessary, thereby recovering the tank 31. The water level in the can be increased. In addition, in order to lower the water level of the recovery tank 31, a leak valve may be installed at the lower portion of the recovery tank 31 or at a target water level to discharge the bubble solution to the outside when necessary.

When air of a predetermined pressure flows from the blower 121 while the inside of the bubble generating pipe 123 is filled with the bubble solution, compressed air is injected into the bubble solution recovery tank 31 through the hole 123a. Bubbles are formed while inflating the bubbles. The bubble thus formed is filled out of the insulating space on one side while moving upward from the bubble solution recovery tank 31. The size of the bubble can be adjusted according to the size of the hole (123a), the air volume of the blower 121, the air pressure, preferably is a bubble of 0.05 ~ 2 cm diameter is preferable.

The operation of the greenhouse having the above structure will be described in detail with reference to the drawings.

First, a process of filling one side of the double layer 10 with bubbles will be described with reference to the drawings. The valve 127 connected to the bubble generating pipe 123 in the one bubble solution recovery tank 31 is opened, and the valve 128 connected to the other pipe 123 is closed. Subsequently, when the blower 121 is operated to blow air of a predetermined pressure through the duct 126 to the pipe 123 on one side, the air is a bubble solution D between the plurality of holes 123a formed in the pipe 123. ) Is inflated with air to discharge bubbles of a predetermined size, preferably about 1 cm in diameter. The bubbles discharged in this way are filled by the excess air from the blower 121 to fill the insulating space 5 on one side of the double membrane 10. In about 2 to 4 minutes, the insulating space 5 on one side of the double membrane 10 is filled with bubbles.

Subsequently, to fill the insulating space 5 of the other double membrane 10 with bubbles, the valve 127 connected to the one pipe 123 is closed and the valve 128 connected to the other pipe 123 is opened in the above-described manner. I can fill it.

On the other hand, if you want to fill the heat insulating space (5) on both sides at the same time to operate the blower 121 in a state in which both of the valves (127, 128) open, supply the compressed air to the pipe (123). In particular, after filling the bubbles in the insulating space (5) on both sides, it is preferable to supply air to both sides at the same time in the case of replenishing the bubbles disappearing over time by operating the blower 121 every predetermined time.

On the other hand, when the size of the generated bubble is too large to easily break, the level of the bubble solution (D) in the bubble solution recovery tank 31 is increased, and the speed of the fan of the blower 121 is increased to supply to the pipe 123. By increasing the amount of air to be made, the bubble size can be formed to a predetermined size. On the contrary, when the air volume is less than that of the bubble solution, the mobility of the bubble is reduced, and an increase in the weight of the bubble may cause a problem that an excessive load is applied to the frame and the sheet. In this case, the bubble level may be adjusted to a predetermined size by lowering the level of the bubble solution D, reducing the speed of the fan of the blower 121, or opening the leak valve 129 to reduce the air volume.

FIG. 6 is a schematic view of a greenhouse including a thermal insulation and a sun shade device using bubbles according to a third embodiment of the present invention, and FIG. 7 is a perspective view of the bubble generating unit of FIG. 6. The same reference numerals are used for the same components, and detailed descriptions are omitted.

6 and 7, a blower 221 for supplying air of a predetermined pressure is disposed on the bubble solution reservoir 230 storing the bubble solution D. Referring to FIGS. The container 231 of bubble solution is disposed in the reservoir 230, and the compressed air from the blower 121 is delivered to the bubble generator 223 in the bubble solution container 231 by the duct 222.

The bubble generator 223 is formed in the shape of a hollow disk, and a plurality of holes 223a are formed thereon. These holes 223a preferably have a diameter of 1 to 4 mm and are spaced from each other at, for example, 2 cm intervals.

Both sides of the reservoir 230 are provided with ducts 226 connected to the double membranes 10, respectively, and the ducts 226 open and close valves for controlling bubbles supplied to the double membranes 10 on both sides thereof. 227,228 are provided. The duct 226 is used not only as a supply passage for bubbles but also as a passage for the bubble solution in which the bubbles in the double membrane 10 are deposited and returned to the reservoir 230.

On the other hand, the upper portion of the bubble solution container has an open structure so that the bubbles generated by the compressed air supplied from the blower 221 to the bubble generating unit 223 is supplied to the insulating space 5 through the duct 226. In addition, the bottom surface of the bubble solution container 231 and the bottom surface of the bubble generating unit 223 is preferably formed in a structure sharing the bottom surface of the reservoir 230.

One side of the bubble solution container 231 has a through hole 231a, which is a passage for supplying the bubble solution of the storage tank 230 to the bubble solution container 231, and is formed inside the through hole 231a. Means for opening and closing 231a are provided. The opening and closing means, for example, connects the opening and closing portion 243 in contact with the through-hole 231a, the support 242, the opening and closing portion 243 and the support 241, and the support 242 fixed at one point therebetween. When the container 231 of the bubble solution is lowered below a certain level, the bure 241 is lowered and the opening and closing part 243 is raised to open the through hole 231a to open the bubble solution container (from the reservoir 230). When the bubble solution flows into the container 231, and the container 231 of the bubble solution rises to a certain level, the opening 241 is upward and the opening and closing part 243 blocks the through hole 231a from the storage tank 230. The bubble solution is prevented from flowing into the bubble solution container 231. That is, the water level in the bubble solution container 231 is made constant.

On the other hand, it is preferable that the motor (not shown) for driving the fan of the blower 221 makes the speed controllable so that the air volume can be controlled.

The operation of the greenhouse having the above structure will be described in detail with reference to the drawings.

First, a process of filling one side of the double layer 10 with bubbles will be described with reference to the drawings. One valve 227 is opened, and the other valve 228 is closed. Subsequently, when the blower 221 is operated to send air of a predetermined pressure to the bubble generator 223, the air is a predetermined size, preferably 0.5 to 2 cm in diameter, through the hole 223a of the bubble generator 223. Bubbles of a degree are generated and discharged into the insulating space 5 on one side. The bubbles discharged in this way are filled by the excess air from the blower 221 to fill the insulating space 5 on one side of the double membrane 10. In about 2 to 4 minutes, the insulating space 5 on one side of the double membrane 10 is filled with bubbles.

Subsequently, in order to fill the insulating space 5 of the other double membrane 10 with bubbles, one valve 227 may be closed and the other valve 228 may be opened to fill the method.

On the other hand, if you want to fill the heat insulating space (5) on both sides at the same time, it is enough to generate and supply bubbles by the above method while the valves (227, 228) are both open. In particular, after filling the bubbles in the heat insulating space (5) on both sides, it is preferable to supply air to both sides at the same time in the case of replenishing the bubbles disappearing over time by operating the blower 121 every predetermined time.

On the other hand, if the size of the generated bubble is too large to break easily, the speed of the fan of the blower 221 can be increased to increase the air volume to form a bubble size to a predetermined size. Conversely, when there is less air compared to the bubble solution, the mobility of the bubble is lowered, and an increase in the weight of the bubble may cause a problem that an excessive load is applied to the frame and the double membrane. In this case, the fan size of the blower 221 may be lowered to reduce the air volume to adjust the bubble size to a predetermined size.

Bubbles formed in the thermal insulation space 5 in the double membrane 10 as described above not only not only keeps warm in winter, but also acts as a sunshade in the day so that crops in the greenhouse do not die due to strong sunlight in summer. It is also possible to form shades.

As described above, the thermal insulation and sunshade device using the bubble according to the present invention serves as a sunshade by generating bubbles during the day or summer, and selectively perform a warming role to protect from cold outside air at night or winter. There is an advantage to this.

Although the present invention has been described with reference to the embodiments with reference to the drawings, this is merely exemplary, it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined only by the appended claims.
