Description

{SOLAR ENERGY GREENHOUSE}

The present invention relates to a solar energy greenhouse device, and more particularly to a solar energy greenhouse device having a thin film solar cell assembly of unequal spacing distance.

A greenhouse is a private building built to grow plants (flowers, vegetables, fruits, etc.) that protects plants from the effects of weather, temperature or pests, and makes plants grow smoothly and quickly. Particularly, in the tropical region or in one region, the growth promotion effect of the plant due to the appropriate temperature and humidity environment provided by the greenhouse is more remarkable.

Greenhouses generally have a roof that can transmit light. Solar light is irradiated to plants through the roof to allow plants to perform photosynthesis. Furthermore, the greenhouse has a number of air conditioning facilities that control temperature and humidity, and controls the temperature and humidity in the greenhouse to be optimal for plant growth. In addition, equipped with a sprinkler, water is regularly sprayed on plants.

As these devices operate, greenhouses consume large amounts of power. As a result, the electricity tax is a heavy burden for the users (farmers, etc.) who use the greenhouse. Here, a technique has been proposed in which a light-transmitting thin film solar cell is attached to a place where the light is strongest in the greenhouse and the amount of sunshine is most sufficient (generally, a roof), and power is supplied to the plant without affecting light irradiation.

Thin-film solar cells, however, still have some translucency, but they still cause some shading or absorption of sunlight, and if sunlight is not enough, it can affect plant growth.

For this reason, the inventors of the present invention have come to the proposal of the present invention which draws attention to the above drawbacks, derives a reasonable design, and can effectively improve the drawbacks.

1 and 2 show a first embodiment of a solar energy greenhouse 100 according to the present invention. The solar energy greenhouse 100 includes a body structure 10, a roof structure 20, and a plurality of solar cell assemblies 30. Here, the spacing distance between the thin film solar cell assemblies 30 is uneven. The transparent material is visible in the space distance portion between the thin film solar cell assemblies 30 (see the transparent plate 22 shown in Fig. 1).

That is, in the solar energy greenhouse 100 according to the present invention, in order to give a sufficient amount of light to the plants shown in FIG. 2, the irradiation angle of the sunlight 300 or the arrangement of the plants 200 in the solar energy greenhouse 100 The layout design of the thin film solar cell assembly 30 is determined. In other words, the spacing distance between the thin film solar cell assemblies 30 is uneven, so that the solar cells 300 are directly transmitted from the spacing distance into the solar energy greenhouse 100, Compensates for some shielded or absorbed sunlight 300, and provides a sufficient amount of light throughout as a whole. Hereinafter, a description of the structure of the solar energy greenhouse 100 itself and a layout design of the thin film solar cell assembly 30 will be described.

Specifically, the body structure 10 includes a plurality of bases 11, a plurality of brackets 12, and a plurality of support plates 13. The base 11 is fixed to the ground and the bracket 12 is fixed to the base 11 and the support plate 13 is fixed to the bracket 12. [ These support plates 13 are made of a translucent or opaque material. In case of a translucent material, the material of the support plate 13 may be glass or plastic.

By virtue of the support effect of the body structure 10, the roof structure 20 is installed in the body structure 10. [ The roof structure 20 includes a plurality of brackets 21 and a translucent plate 22. The bracket 21 is fixed to the bracket 12 and the translucent plate 22 is fixed to the bracket 21, The material of the plate 22 may be glass or plastic.

The roof structure 20 is designed to have an inclined shape and the lowest place of the roof structure 20 is defined as the eave 23 and the roof structure 20 is designed to have a tapered shape, Is defined as a crest section (24).

The body structure 10 and the roof structure 20 together form a closed space. In addition, temperature and humidity control means are provided to allow the plants 200 to be grown inside the body structure and inside the solar energy greenhouse 100 by giving suitable conditions to the plants in the closed space. The outer shape of the body structure 10 and the roof structure 20 is not limited to that shown in the drawings, and may be another outer shape. For example, the roof structure 20 may be arcuate.

Instead of the glass or plastic, the supporting plate 13 of the body structure 10 and the translucent plate 22 of the roof structure 20 may be flexible light-transmitting fabrics (not shown).

These thin-film solar cell assemblies 30 are installed on the roof structure 20, and more particularly, on the surface of the roof structure 20. Each thin film solar cell assembly 30 includes a plurality of thin film solar cells 31 which are connected to the eaves 23 or the bottom surface of the roof structure 20, Are arranged in a straight line along the stretching direction of the crest portion (24). Examples of the thin film solar cell 31 include thin film solar cells such as amorphous, microcrystalline silicon, and nanocrystal silicon. Each of the thin-film solar cells 31 can also be manufactured directly as a thin rod-shaped or large-area thin-film solar cell 31.

The solar light 300 shown in Fig. 2 is absorbed by the thin film solar cell 31 and converted into electric power. When the surplus sunlight 300 is irradiated on the thin film solar cell 31, a part of the sunlight 300 is transmitted through the thin film solar cell 31, And enters the interior of the energy greenhouse 100 (i.e., the lower portion of the roof structure 20).

In this case, when the entire roof structure 20 is covered with the thin film solar cell assembly 30 (not shown), more power can be generated. However, when the solar light 300 entering the solar energy greenhouse 100 ). When the amount of irradiation of the plant 200 to the sunlight 300 is insufficient, the growth of the plant 200 is affected.

  In order to overcome such a problem, the entire roof structure 20 is not completely covered with the thin film solar cell assembly 30, but the thin film solar cell assemblies 30 are spaced apart from each other, And directly enter the interior of the solar energy greenhouse 100, thereby increasing the amount of sunlight 300 irradiated on the plant without being absorbed or shielded by the thin film solar cell 31. Considering the angle of irradiation of the sunlight 300 and the position of the plant 200, the distance between the thin film solar cell assemblies 30 is made uneven so that more sunlight 300 is transmitted to the plant 200, .

It should be noted that the transparent plate 22 is disposed at a distance between the thin film solar cell assemblies 30. In other words, the transparent plate 22 may be disposed at the lower portion of the thin film solar cell assembly 30 (particularly, the portion not shielded or covered by the thin film solar cell assembly 30) and may be disposed between the thin film solar cell assemblies 30 The translucent plate 22 may be provided. That is, the thin-film solar cell assembly 30 and the transparent plate 22 are alternately arranged from the eaves 23 toward the crest portion 24, and opposite sides of the transparent plate 200 are each formed as a pair of thin- And contacts one side of the battery assembly 30.

2, when the sun is close to the eaves 23 and away from the crest 24, under the irradiation conditions of the sunlight 300, the sunlight 300 near the crest 24 The body structure 10 is irradiated without being irradiated on the plant 200. Conversely, the sunlight 300 near the eaves 23 is directly irradiated to the plant 200. [ The gap distance between two adjacent thin film solar cell assemblies 30 close to the eave end 23 is set to be smaller than the distance from the ridge 24 to the plant 200 Is larger than the distance between the two adjacent thin film solar cell assemblies (30).

As described above, the solar light 300 near the eaves 23 passes through the clearance distance in a large amount, directly enters the inside of the solar energy greenhouse 100, and is irradiated on the plant 200.

In addition, FIG. 2 shows that a carbon fiber 400 is installed on the bottom surface of the greenhouse. When the carbon fiber is installed on the bottom of the greenhouse, the solar energy generated by the thin film solar cell assembly It can be supplied to the floor inside the greenhouse, which can supply the heat energy to the plants growing inside the greenhouse, thus saving the energy required to heat the inside of the greenhouse.

3, the sunlight 300 is irradiated from the upper left of the solar energy greenhouse 100 under the irradiation condition of the sunlight 300 when the sun is close to the crest portion 24 and away from the eaves . In this case, the sunlight 300 near the eaves 23 is irradiated to the main body structure 10 without being irradiated to the plant 200, and conversely, the sunlight 300 near the ridge 24 is irradiated to the plant 200). Therefore, the clearance distance between two adjacent thin film solar cell assemblies 30 near the crest portion 24 is larger than the clearance distance between two adjacent thin film solar cell assemblies 30 near the eave 23.

4, when the sun is close to the eave end 23 and away from the crest 24, and the arranged position of the plant 200 in the solar energy greenhouse 100 is away from the eave end 23, It is difficult for the sunlight 300 near the eaves 23 and crest 24 to be irradiated on the plant 200. [ In such a case, the spacing distance between the thin film solar cell assemblies 30 close to the eaves 23 and the crest 24 is reduced, and the distance between the solar cell 300 at the eaves 23 and the crest 24 is reduced, So as to irradiate the thin film solar cell assembly 30 as much as possible. In this case, the entire spacing distance between the thin film solar cell assemblies 30 is randomly distributed, but is distributed corresponding to the position of the sunlight 300 and the plant 200, so that the solar light 300 can be used sufficiently do.

In order to make it easy to adjust the spacing distance of the thin film solar cell assemblies 30, the thin film solar cell assemblies 30 are provided with displacement means to randomly adjust the allocation method of the spacing distances between the thin film solar cell assemblies 30 .

5 is a view showing a second embodiment of the solar energy greenhouse 100 according to the present invention. As shown in Fig. 5, the difference between the solar energy greenhouse 100 according to the second embodiment and the first embodiment is that the solar energy greenhouse 100 according to the second embodiment further includes a plurality of mobile devices 40 And each thin film solar cell assembly 30 is installed in the roof structure 20 by one moving device 40. [

The mobile device 40 includes at least one slide mechanism 41 and at least one driver 42 wherein the slide mechanism 41 is installed on the surface of the roof structure 20 and the driver 42 is mounted on the slide mechanism (41), and the thin film solar cell assembly (30) is installed in the slide mechanism (41). The slide mechanism 41 is a mechanism for linearly moving a part of the mechanism, for example, a linear rail or the like. The driver 42 applies power to the slide mechanism 41 to linearly move it, and controls the amount of linear motion generated in the slider mechanism 41. The driver 42 is a step motor or a servo motor.

The thin film solar cell assemblies 30 can be moved on the roof structure 20 by the moving device 40 to change the spacing distance between the thin film solar cell assemblies 30. When the irradiation angle of the solar light 300 changes according to time or area or when the position of the plant 200 is changed, the distance between the thin film solar cell assemblies 30 is adjusted accordingly. As such, the solar light 300 is irradiated to the thin film solar cell assembly 30 as much as possible as much as possible to the solar light 300 that is irradiated to the plant 200 as much as possible and can not be irradiated to the plant 200.

6 is a view showing a third embodiment of the solar energy greenhouse 100 according to the present invention. 6, the difference between the solar energy greenhouse 100 according to the third embodiment and the first embodiment is that the solar energy greenhouse 100 according to the third embodiment further includes a plurality of rotating devices 50 And each of the thin film solar cell assemblies 30 is installed in the roof structure 20 by a single rotating device 50, respectively.

Similar to the mobile device 40, the rotating device 50 includes at least one rotating device 51 and at least one driver 52, and the rotating device 51 is installed in the roof structure 20 , The driver 52 is connected to the rotating mechanism 51, and the thin film solar cell assembly 30 is installed in the rotating mechanism 51 again. The rotating mechanism 51 is a mechanism for rotating a part of the mechanism, for example, a gear train and the like. The driver 52 applies power to the rotating mechanism 51 to rotate and controls the amount of rotational motion generated in the rotating mechanism 51. [ The driver 52 is a step motor or a servo motor.

The thin film solar cell assembly 30 can adjust the inclination angle of the thin film solar cell assembly 30 by the rotating device 50 so that the thin film solar cell 31 is irradiated perpendicularly to the sunlight 300 as much as possible. As can be seen from many documents, when the solar light 300 is irradiated perpendicularly to the thin film solar cell 31, the thin film solar cell 31 can generate more electric power. For this reason, the solar energy greenhouse 100 according to the third embodiment has the advantages of the first embodiment, and the thin film solar cell 31 can generate more electric power.

7 is a view showing a fourth embodiment of the solar energy greenhouse 100 according to the present invention. 7, the difference between the solar energy greenhouse 100 according to the fourth embodiment and the first embodiment is that the solar energy greenhouse 100 according to the fourth embodiment includes the heating device 60, the temperature sensor 70 And a humidity sensor 80, as shown in Fig.

The heating device 60 is connected to the thin film solar cell 31 of each thin film solar cell assembly 30 and the transparent plate 22 of the roof structure 20. The heating device 60 generates heat, The battery cell 31 and the transparent plate 22 can be heated. The heating device 60 is composed of a heating wire and its controller or the like. The temperature sensor 70 and the humidity sensor 80 are respectively connected to the heating device 60. The temperature sensor 70 measures the temperature of the external environment and transmits a temperature signal to the heating device 60, (80) measures the humidity of the external environment and transmits the humidity signal to the heating means (60).

When snow is deposited on the thin film solar cell 31 and the transparent plate 22 when the solar greenhouse 100 is in a cold and snowy region, the thin film solar cell 31 of the solar cell 300 and the plant (200). ≪ / RTI > The heating device 60, the temperature sensor 70, and the humidity sensor 80 can prevent such snow from being deposited.

When the snow falls, the outside temperature becomes below the zero degree, and the humidity also becomes high. Therefore, when the temperature sensor 70 and the humidity sensor 80 measure the abnormal temperature or humidity, the temperature and humidity signals are transmitted to the heating device 60. [ The heating device 60 starts to start and generates heat, and when the snow hits the heating device 60, the heating device 60 melts into the liquid and flows down. As described above, the solar light 300 can be sufficiently irradiated to the thin film solar cell 31 and the plant 200 without the snow being always deposited on the thin film solar cell 31 and the transparent plate 22.

The heating device 60 may be connected only to the thin film solar cell 31 of the thin film solar cell assembly 30 or may be connected only to the transparent plate 22 of the roof structure 20. [ Further, it may not be connected for every thin film solar cell 31 or for every transparent plate 22.

8 is a view showing a fifth embodiment of the solar energy greenhouse 100 according to the present invention. 8, the difference between the solar energy greenhouse 100 according to the fifth embodiment and the first embodiment is that the solar energy greenhouse 100 according to the fifth embodiment has a plurality of reflection mirrors 90 And these reflection mirrors 90 are installed on the lower side of the roof structure 20 and on the inside of the body structure 10.

When the sunlight 300 enters the solar energy greenhouse 100, a part of the sunlight 300 is irradiated to the reflecting mirror 90, and the sunlight 300 is reflected, The traveling direction of the sunlight 300 is changed so as to be directed toward the sunlight 200. As such, sunlight 300 can be irradiated to more plants 200.

The above-described moving device 40, the rotating device 50, the heating device 60, the temperature sensor 70, the humidity sensor 80, and the reflecting mirror 90 may be partially or wholly used in the solar energy greenhouse 100 And is not limited to being used solely. In addition, the solar energy greenhouse 100 according to the preferred embodiment may include a lighting device, a sprinkler, or an air conditioning facility (not shown).

As described above, the solar energy greenhouse 100 according to the present invention absorbs the sunlight 300 and converts it into electric power, provides the solar energy to the use of other facilities of the greenhouse 100, It is possible to reduce the consumption of electric power supplied from the electric power company, thereby reducing the electricity tax paid by the user. The spacing distance between the thin film solar cell assemblies 30 is determined according to the irradiation angle of the sunlight 300 and the position of the plant 200 so that the distance between the thin film solar cell assemblies 30 and the plant 200 The irradiation amount of the solar light 300 is preferably distributed so as to improve the power generation amount of the thin film solar cell assembly 30 and the growth rate of the plant 200. [

Further, as shown in Fig. 9, the forced ventilation device 100-1 is further provided in the greenhouse, so that the air inside the greenhouse can be forcibly discharged to the outside.

In the meantime, according to the present invention, the dust measuring means 1000 is installed at the inner end of the solar energy greenhouse. If it is determined that there is more dust than the reference result of the measurement result of the dust measuring means 1000, An alarm signal is output to cause the operator to evacuate or remove dust properly since the fine dust around the apparatus is above the reference value.

The dust measuring means 1000 of the present invention includes an infrared transmitting means (A) for emitting infrared rays, a light receiving means for receiving the light emitted from the infrared transmitting means and positioned to face the infrared transmitting means, (D) for controlling the input voltage of the infrared ray transmitting means (A) to increase when the output voltage of the infrared ray receiving means (B) is smaller than a predetermined value, an infrared ray receiving means (C).

The infrared transmitting unit A receives the infrared transmitting control signal from the dust measuring control unit C, determines the infrared transmitting amount, and outputs the changed infrared transmitting amount.

That is, when the result of the infrared ray receiving means B is transmitted to the dust measurement control section C, the dust measurement control section C predicts the dust generation amount based on the data of the infrared ray receiving means B, And outputs a control signal to the infrared ray transmitting means (A) to adjust the infrared ray transmission amount to induce the output.

That is, the light amount data outputted from the infrared ray receiving means is read by the dust measurement control unit, and the light amount of the infrared light emitting means is automatically controlled based on the read light amount data, so that the sensitivity adjustment is automatically maintained constant. So that the measurement can be performed while maintaining the sensitivity state.

In other words, the dust measurement control section C determines that the degree of contamination is high when the amount of received light of the infrared ray receiving means B is low, and outputs a control signal to increase the light amount of the infrared ray transmitting means A If the amount of light received by the infrared ray receiving means C is too high, a contamination-free state or a precise measurement becomes difficult. Therefore, a control signal is outputted so as to lower the light amount of the infrared ray transmitting means A That is, it is necessary to keep the amount of infrared transmission light in an appropriate state. The infrared ray amount measured through the infrared ray receiving means is accurate and the dust amount can be more precisely predicted. Therefore, the dust amount data measured by the dust measurement control unit of the present invention can output the dust measurement result with high reliability.

That is, holes are formed in the housing 5 at regular intervals in advance, and the sliding balls 5b are temporarily engaged with the holes while moving the fixing portions. At this time, the sliding balls are spread to the left and right due to the action of the elastic spring 4a So that the fixed state is maintained.

Accordingly, it is possible for the user to freely adjust the position of the fixing portion.

The present invention is configured such that the output of the transmitting element 2 is automatically adjusted in response to a change in temperature so that the shape memory spring 3 is set to a basic temperature and then the shape memory spring is extended when the temperature rises, The shape memory spring 3 is reduced and the light of the transmitting element 2 is lowered and output when the temperature is lowered.

That is, since the dust is distributed in the gas, the movement becomes active when the temperature rises, so that the dust concentration can be checked more accurately than when the output of the transmitting element 2 is lowered. When the temperature is lowered, 2) can be checked more precisely than when the output is increased.

Accordingly, the present invention allows the concave lens group 1 to flow in a more accurate manner by reflecting the temperature change.

In actual operation, first, the light of the transmitter is outputted through the third concave lens 1c, which is installed at the center of the concave lens group 1, basically.

When the ambient temperature rises, the shape memory spring expands and the second concave lens 1b, which is located on the right side of the third concave lens 1c and whose concave angle is lower than that of the third concave lens 1c, Thereby lowering the optical output of the transmitting element 2 and outputting it. When the ambient temperature is lowered, the shape memory spring 3 contracts and the fourth concave lens 1d located on the left side of the third concave lens 1c and having a concave angle higher than that of the third concave lens 1c is transmitted So that the light output of the transmitting element 2 is increased and outputted.

As described above, according to the present invention, the shape memory spring 3 automatically expands and contracts in response to the ambient temperature, thereby promoting a change in the amount of light according to the movement of dust, thereby grasping a more accurate dust concentration, .

On the other hand, according to the present invention, the transmission control section 8 forcibly moves the concave lens group 1 according to the density of dust so as to grasp the most accurate dust density. Even if there is no temperature change, So that the concentration of the dust can be grasped accurately.

That is, in the present invention, when the dust measurement control unit C outputs a control signal in order to facilitate the change of the amount of light of the infrared ray transmission means, the transmission control unit 8 recognizes the control signal and drives the heat generation means 6 and the thermoelectric element 7 So that the most appropriate infrared transmission is made.

First, the infrared light is basically outputted through the third concave lens 1c provided at the center of the concave lens group 1. When the infrared light is to be output with a small reduction, the transmission control unit 8 controls the heating means 6 ) Of the third concave lens 1c to generate heat to cause the shape memory spring to expand and thus the transmission element 2 is fixed so that the concave lens group 1 moves and the second concave The output light of the transmitter is outputted through the second concave lens while the lens 1b moves to the position of the transmitting element 2. [

When the infrared light is to be outputted in a further reduced amount, the transmission control unit 8 operates the heat generating unit 6 to generate more heat to cause the shape memory spring 3 to expand more, and accordingly the concave lens group 1 And the first concave lens 1a is moved to the position of the transmitting element 2 so that the light of the transmitting element 2 is output through the first concave lens 1a.

When the infrared light is to be outputted with a high light output, the transmission control unit 8 drives the thermoelectric element 7 to generate cooling heat so that the shape memory spring 3 is contracted, and accordingly the concave lens group 1 moves The fourth concave lens 1d provided on the left side of the third concave lens 1c is located in the transmitting element and accordingly the light of the transmitting element 2 is outputted through the fourth concave lens 1d.

When the infrared light is to be outputted with higher light output, the transmission control unit 8 drives the thermoelectric element 7 to generate more cooling heat so that the shape memory spring 3 is further contracted and accordingly the concave lens group 1 The fifth concave lens 1e is moved to the position of the transmitting element 2 so that the light of the transmitting element 2 outputs light through the fifth concave lens 1e.

The concave lens group is designed to vary the degree of output of infrared light according to the concave angle of the central portion. The third concave lens 1c is basically provided at the center of the working rod and forms a concave angle of 25 degrees.

The second concave lens 1b is used for outputting a slightly reduced amount of infrared light and is provided on the right side of the third concave lens 1c and forms a depression angle of 15 degrees.

The first concave lens 1a is used when it is necessary to further reduce the infrared light and is provided on the right side of the second concave lens 1b and forms a depression angle of 5 degrees.

The fourth concave lens 1d is used when it is necessary to output the infrared ray with higher light output, and is provided on the left side of the third concave lens 1c and forms a depression angle of 35 degrees.

The fifth concave lens 1e is used when it is necessary to output the infrared ray with a higher intensity, and is provided on the left side of the fourth concave lens 1d and forms a concave angle of 45 degrees.
