Description

Apparatus for plant-cultivation which can use the inner and outer light source, and generate electricity}

The present invention relates to a plant cultivation apparatus, and more particularly, to install a heat collecting plate (or heat sink, hereinafter referred to as "collecting plate") that reflects light, and to control the angle of the heat collecting plate to more effectively control the external light source to the plant. In addition, the temperature inside the device can be freely controlled by using a heat collecting plate as a heat collecting or heat dissipating means, and a part or the whole is made of a light-transmitting dye-sensitized photovoltaic cell to enable self-generation at the same time. The present invention relates to a self-generating plant cultivation device combined with internal and external light sources.

There is a plant cultivation facility that artificially regulates the environment so that plants can grow by artificially supplying or controlling the light, temperature, humidity, and nutrients necessary for the growth of edible, medicinal or ornamental plants (hereinafter referred to as "plants"). This plant cultivation facility is to cultivate plants by cultivating high-quality plants as an attribute, or by creating an environment in which plants can grow artificially even in an environment unsuitable for growing plants. Normally, plant cultivation facilities have air conditioning and heating means for controlling temperature, humidification means for controlling humidity, etc. inside a cultivation facility such as a greenhouse or a plastic house. In some cases, additional lighting means are provided for the purpose.

Recently, a plant cultivation device (also known as a "plant factory") that grows plants by artificial lighting (LEDs, fluorescent lights, incandescent lamps, etc.) instead of natural light (sunlight) in an extremely controlled environment is developed / operated. It is becoming.

Plant cultivation apparatus using only the conventional artificial light source, and consumes a large amount of external electricity for the operation of the electrical equipment, such as artificial light source, heating and cooling means and humidification means, and is thoroughly blocked from the outside There was a problem that plants could not use natural light at all.

In addition, the plant cultivation device of the form of a combined artificial light source and an external light source has a problem that a sufficient light source is not irradiated on the plant when the irradiation angle of natural light changes over time when it is composed of a small chamber (chamber).

The present invention was developed to solve the problems of the prior art as described above, by using a light-transmitting dye-sensitized photovoltaic cell is possible to use an external light source and self-power generation, by adjusting the angle of the heat collecting plate that can reflect light outside It is an object of the present invention to provide a plant cultivation apparatus that can not only effectively transmit a light source to a plant, but also simultaneously control the temperature inside the apparatus by using a heat collecting plate as a heat collecting or heat dissipating means.

The present invention for achieving the above object is a plant cultivation apparatus capable of driving the electrical equipment using the electricity generated by itself, (A) having one or two or more plant cultivation beds in the interior, except the base portion or A case equipped with a dye-sensitized photocell, which transmits light on the entire surface thereof; (B) an internal light source module provided inside the case; (C) a power supply unit for supplying the electricity generated in the dye-sensitized photocell to the internal light source module.

According to the present invention, the dye-sensitized photovoltaic cell produces electricity during the daytime by sunlight or external illumination (hereinafter referred to as "external light source" or "external light"), and accumulates electricity, and the daytime day is clouded so that the amount of light is insufficient. Or when there is no external light at night, it can drive the electrical equipment including the internal light source. In addition, during the daytime (even at night when there is external light), the external light passing through the transparent case surface can be used for plant growth.

In order for all plants to grow evenly, the intensity of light irradiated to each plant must be constant, which is inversely proportional to the square of the distance from the light source. Therefore, in the conventional plant cultivation apparatus according to the prior art, the internal light source module is installed horizontally above the plant cultivation bed so that the distance between the light source and the plant is constant.

However, in the plant cultivation apparatus according to the present invention, which allows the use of an external light source under conditions, when the internal light source module is installed as described above, the internal light source module blocks the external light so that the external light cannot be reflected on the plant. Can be.

In order to solve this problem, in the plant cultivation apparatus according to the present invention, 1) the inner light source module is horizontally mounted on the upper side of the plant cultivation bed, but when using the external light, one side of the inner light source module can be folded to the side wall of the case. Is hinged to the inside of the case, or (2) it is preferable to mount the inner light source on the side wall so that the inner light is evenly reflected on the side surface of the plant.

On the other hand, a considerable amount of heat is generated in the process of generating electricity in the dye-sensitized photocell and the operation of the internal lighting. If the temperature inside the plant cultivation apparatus is too high, the plant will die, so heat dissipation means for dissipating heat to the outside may be additionally installed.

The heat dissipation means may include ① a heat collecting plate that collects heat generated from an external light source or an internal light source and transmits it to the outside for discharge; or ② a temperature sensor mounted inside the case, and operates according to the temperature sensed by the temperature sensor. It may be composed of one or more ventilation devices for introducing and discharging the heat generated in the light source or the internal light source to the inside / outside.

As described above, according to the present invention, the plant cultivation apparatus may be configured as part or the whole surface of the dye-sensitized photovoltaic cell to generate electricity by receiving light from a light source, and to use the electricity to operate electrical equipment, thereby saving electricity. It works.

In addition, the plant cultivation apparatus according to the present invention by making a part or the whole surface of a transparent material or a light-transmissive solar cell so that natural light or external light is reflected by the heat collecting plate and irradiated perpendicularly to the plant without driving the internal light source, By using an external light source and an internal light source alone or in combination, there is an effect of promoting the growth of plants by allowing more light to be irradiated on the plants.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings. However, the accompanying drawings are only examples for easily describing the content and scope of the technical idea of the present invention, and thus the technical scope of the present invention is not limited or changed. In addition, it will be apparent to those skilled in the art that various modifications and changes can be made within the scope of the present invention based on these examples.

Internal and external light source combined self-powered plant cultivation apparatus according to the present invention is to enable the operation of the electrical equipment using the electricity generated by itself, it is possible to supply light to the plant more efficiently.

Plant cultivation apparatus according to the present invention can be configured in the form of a large building, such as a greenhouse or a small chamber (chamber) installed in the interior of the building. Hereinafter, a small chamber type will be described as an example, but the claims are not limited thereto.

The plant cultivation apparatus according to the present invention, like a conventional plant cultivation apparatus, the plant cultivation bed (11) that serves as the soil in which the plant grows, and the cultivation environment of the plant planted in the plant cultivation bed (11) The case 1 to disconnect is included.

As shown in FIG. 1, the case 1 may be a hexahedron, a cylinder, or a polyhedron, and a space in which the plant is grown is formed therein. One or more plant material beds 11 are installed in the case 1.

The plant cultivation bed 11 is a container of a predetermined depth that contains the vegetation soil containing nutrients, or nutrient solution, such as hydroponic cultivation facilities. The plant cultivation bed 11 may be installed only one, as shown in Figure 1 or two or more may be installed as shown in FIG. Since the plant cultivation bed 11 can be selected from any of those already developed and used, detailed description thereof will be omitted.

The present invention is to install the dye-sensitized photovoltaic cell 12, which is a self-developing means in the conventional plant cultivation apparatus according to the present invention configured as described above, and to be able to receive light from both the external light source and the internal light source.

The dye-sensitized photovoltaic cell 12 generates electricity in response to light irradiated and installed on some or all surfaces except the base of the case 1, and the generated electricity is generated through an internal light source 3 through a power supply unit 3 to be described later. It is supplied to electronics such as modules.

The dye-sensitized photovoltaic cell 12 reacts not only with DS-Sensitized solar cells (DSSC) or with sunlight but also with ordinary illumination light. The DSSC is a photovoltaic cell composed of a light-sensitive dye that absorbs light, a nano titania electrode supporting the dye, an electrolyte, and a catalytic counter electrode. Various types of dye-sensitized photocells are known in the art, and the present invention is one of the methods of utilizing the same, and thus, detailed description of the dye-sensitized photovoltaic cells will be omitted.

In the dye-sensitized photovoltaic cell 12, the light receiving surface must be perpendicular to the direction in which the external light is incident, thereby increasing efficiency of the light receiving amount. Accordingly, the dye-sensitized photovoltaic cell 12 is preferably installed on the upper surface or one side of the case 1 facing the external light source as shown in FIGS. 1 to 5 and 9.

As described above, the conventional plant cultivation apparatus using only an artificial light source is shielded from light shielding, and only an internal light source supplies light to plants, thereby lowering energy efficiency. On the other hand, the plant cultivation device that combines the artificial light source and the external light source has a disadvantage that when the small chamber (chamber) is composed of the irradiation angle of the natural light changes over time, a sufficient light source is not irradiated to the plant. In order to solve this problem, the plant cultivation apparatus according to the present invention allows the angle of the heat collecting plate to be adjusted as necessary to allow as much external light to be irradiated on the plant as possible.

In the present invention, the external light source is the sun or the external illumination, the internal light source is an internal light source module 2 equipped with a light source 21 of any one type of LED, fluorescent lamp, incandescent lamp, high pressure sodium lamp and halogen lamp.

As described above, in order for all plants to grow evenly, the intensity of light irradiated to each plant should be as constant as possible. The intensity of the light becomes weaker as the distance from the light source increases. Therefore, in order to make the distance between the plant and the internal light source module 2 constant, the internal light source module 2 is preferably installed to be parallel to the plant cultivation bed 11.

When the internal light source module 2 is installed in an optical path of external light, external light is blocked.

In order to solve such a problem, that is, in order to prevent the external light source from being blocked by the internal light source module 2, one side of the internal light source module 2 is hinged to the inner wall of the case 1 so that external light is not incident. When not, the internal light source module 2 is on the plant cultivation bed 11, and when the external light is incident, the internal light source module 2 can be folded toward the side wall of the case 1 (see FIGS. 2 to 5) or FIG. As shown in FIG. 7, the internal light source module 2 is mounted on the inner side wall of the case 1 in multiple stages so that the irradiated light is directed to the plant planted in the plant cultivation bed 11, or as shown in FIG. 8. Reflecting grooves may be formed in the inner sidewall of the case 1 and a light source 21 may be provided therein.

On the other hand, the plant cultivation apparatus according to the present invention configured as described above generates a lot of heat in the process of the internal and external light source is operating and the dye-sensitized photovoltaic cell 12 generates electricity. If the temperature inside the plant cultivation apparatus is too high, the plants are dead, so the heat dissipation means 4 may be additionally installed to discharge heat to the outside.

Although various kinds of heat dissipation means 4 may be considered, as shown in FIGS. 2 to 6, the heat dissipation means 4 may be configured by a plurality of heat collecting plates 41 that simply absorb heat and transfer it to the outside. .

The heat collecting plate 41 serves to absorb heat and discharge the heat to the outside, and is made of a material having excellent thermoelectric efficiency. The heat collecting plate 41 is preferably installed in the upper part of the case 1 in consideration of the fact that hot air collects upward. In this case, in order to effectively absorb the heat generated from the dye-sensitized photovoltaic cell 12, it is preferable that one side is installed to contact the inner surface of the dye-sensitized photovoltaic cell 12.

In addition, the heat dissipation means may be a configuration in which the dye-sensitized photocell heat dissipation unit and the LED heat dissipation unit are integrated as shown in FIG. 10 when the external light is not used for plant growth.

On the other hand, the heat collecting plate 41 so that the external light is well irradiated to the plant, the angle is preferably adjusted so as to correspond to the direction in which the external light is incident. For example, as illustrated in FIG. 6, a plurality of heat collecting plates 41 may be arranged at equal intervals, and driving means 42 may be provided to rotate the heat collecting plates 41 in a pendulum shape.

When blocking external light, adjacent heat collecting plates are brought into contact with each other as shown in FIG. 3, and when passing external light, the heat collecting plates are inclined toward the external light to be opened as shown in FIG. 5.

Meanwhile, in order to prevent external light from being blocked or absorbed by the heat collecting plate 41 as much as possible, the surface of the heat collecting plate 41 may be manufactured to reflect light.

Another example of the heat dissipation means 4 is a ventilator 5. The ventilator 5 is at least one blower for circulating the internal / external air by operating in accordance with the temperature sensor 51 installed inside the case 1 and the temperature sensed by the temperature sensor 51 ( 52). The ventilation device 5 is preferably installed at one side of the upper part of the case 1 in consideration of the fact that hot air is collected in the upper part of the case 1.

As described above, when the wall of the case 1 is made of a light-transmitting dye-sensitized photovoltaic cell 12 or transparent glass or the like, a part of the light irradiated from the internal light source module 2 is transmitted to the outside and thus is supplied to the plant. Not only will the amount of light give, but the eyes of the outside will be dazzled. Accordingly, the inner wall of the case 1 may be further provided with a reflector 6 that can be opened or closed by rolling up or changing directions, such as curtains or blinds.

The plant cultivation apparatus of the present invention configured as described above includes a power supply unit 3 as a means for accumulating, transforming, and converting electricity generated from the dye-sensitized photovoltaic cell 12 to provide the electrical equipment.

The power supply unit 3 may also include a switching function to provide a commercial power supply when the electricity produced by the dye-sensitized photovoltaic cell 12 is insufficient to drive the electronic device. The power supply unit 3 may be variously modified and detailed description thereof will be omitted.
