Hereinafter, a greenhouse having a snow removal function related to the present invention will be described in more detail with reference to the accompanying drawings. The suffixes "module" and "unit" for components used in the following description are given or used in consideration of ease of specification, and do not have distinct meanings or roles from each other.

1 is a perspective view of a greenhouse having a snow removal function according to an embodiment of the present invention.

As shown, one embodiment of the present invention, a greenhouse with a snow removal function, the frame 10, the vertical frame 20, the transparent cover 30, a transparent planar heating cover 40 to be configured Can be.

The arch frame 10 is erected at regular intervals in the longitudinal direction with respect to the ground, as shown, a plurality can be installed. The number of the frame 10 can be determined by the designer's choice according to the length of the greenhouse to be installed, durability, and the thickness of the transparent cover.

The vertical frame 20 is a component for supporting the plurality of the frame 10 to be connected to each other. Where the vertical frame 20 and the frame 10 meets can be attached by welding. Here, the arch frame 10 and the vertical frame 20 may be made of a metal pipe using aluminum or iron, or may be made of a polymer (plastic).

The transparent cover 30 covers the arch frame 10 and the vertical frame 20, and the inside is sealed to increase the internal temperature higher than the outside temperature according to the greenhouse effect. As the transparent cover 30, a plastic material such as vinyl may be used, or a ceramic material such as glass may be used.

The transparent surface heating cover 40 may be attached to the upper or lower surface of the transparent cover 30, and may be installed along the ground from one of the ceiling portion or the upper portion of the arch frame 10. The transparent planar heating cover 40 serves to melt and remove snow wrapped in the greenhouse 100 by converting electrical energy obtained from a power supply to be described later into thermal energy. Since the transparent planar heating cover 40 generates heat in a non-line plane, not only can the eye melt quickly and widely, but since the transparent heat generating cover 40 is transparent, sunlight is transmitted, so that the greenhouse 100 There is less loss of incoming sunlight. The structure of the transparent heat generating cover 40 will be described in detail with reference to FIG. 2.

In addition, a plurality of transparent heat generating covers 40 may be installed. Depending on the amount of snow that is snowed, the plurality of transparent heat generating covers 40 are independently controlled, so that snow that is snowed efficiently can be removed.

On the other hand, the transparent surface heating film may be installed on the side or the bottom of the greenhouse (100). In this case, the transparent planar heating film 40 may act as a heat source for maintaining the temperature of the greenhouse rather than a role for melting snow.

2 is a cross-sectional view of a transparent planar heating cover used in a greenhouse having a snow removal function according to an embodiment of the present invention.

As shown in FIGS. 2A and 2B, the transparent planar heat generating cover 40 is formed at both ends of the base film 41, the heat generating layer 42 stacked on the base film 41, and the same plane as the heat generating layer. It may include a conductive coating layer 44 and a protective film 43 laminated on the heating layer 42 to protect the conductive coating layer 44 and the heating layer 42.

The base film 41 may be selected from PE FILM, PVC FILM, PP FILM, and PET FILM as a transparent material.

The heat generating layer 42 is for converting electrical energy supplied from a power supply to be described later to heat energy to heat enough heat to melt snow accumulated in the greenhouse. The heat generating layer 42 may include a heat generating element capable of generating heat such as carbon nanotubes or ITO.

In particular, the carbon nanotubes are hexagonal shapes made of six carbons are connected to each other to form a tubular shape. The diameter of the tube is only a few tens of tens of nanometers, which is called carbon nanotubes. Nanometers are one millionth of a meter, usually one hundredth of a hair's thickness. The electrical conductivity per unit area is 100 to 1000 times better than copper, the thermal conductivity is the same as the best diamond in nature, and the strength is 100 times better than steel. Carbon fiber can be broken by only 1% deformation, while carbon nanotubes can withstand 15% deformation. Moreover, this carbon nanotube has excellent exothermicity.

Carbon nanotubes include single-walled carbon nanotubes and multi-walled carbon nanotubes. Since single wall carbon nanotubes are superior in transparency to multiwall carbon nanotubes, it may be desirable for single wall carbon nanotubes to be applied to the present invention.

In the case of carbon nanotubes, the heat generating layer 42 may have a thickness of about 10-100 μm in order to ensure sufficient heat generation and transparency.

Carbon nanotubes have a sunscreen effect. Accordingly, since ultraviolet rays irradiated into the greenhouse are blocked by the transparent heat generating cover 40, it is more advantageous for plant growth.

The protective film 43 may be applied on the heat generating layer 42 to protect the heat generating layer 42 and the conductive coating layer 44 for supplying current to the heat generating layer. The protective film 43 is also made of PE, PVC, PP, PET to ensure transparency, the thickness may be 15㎛ to 60㎛.

The manner in which the transparent surface heating cover having the above-described configuration is installed on the ceiling or the upper side of the greenhouse, which is an embodiment of the present invention, will be described in detail with reference to FIG. 3.

3A to 3C are diagrams for explaining the installation of a transparent planar heating cover 40 used in a greenhouse having a snow removal function according to an embodiment of the present invention.

As shown in FIG. 3A, a plurality of bow frames 10 are installed side by side, and in this state, the transparent cover 30 and the transparent planar heating cover 40 sequentially move the bow frame 10 up and down. Cross-installed, and a clip (fixing tongs) 50 may be further installed to fix it.

Accordingly, the transparent planar heating cover 40 may be easily installed inside the greenhouse 100.

In addition, as shown in FIG. 3B, the transparent surface heating cover 40 may be installed on the transparent cover and fixed by the clip 50 to the bow-shaped frame 10 provided at both ends.

In addition, as shown in Figure 3c, the transparent surface heating cover 40 may be installed in the greenhouse. That is, the transparent surface heating cover 40 may be installed on the inner side of the frame, and the transparent cover 30 may be installed on the outside of the frame. At this time, the transparent surface heating cover 40 may be fixed by the clip 50 from the inside.

Hereinafter, how and when the transparent planar heating cover 40 operates will be described in more detail with reference to the block diagram of FIG. 4.

4 is a block diagram illustrating an electronic structure of a greenhouse having a snow removal function according to an embodiment of the present invention. As shown, the electronic configuration of the greenhouse having a snow removal function of an embodiment of the present invention is a transparent surface heating cover 40, the power supply unit 60, the communication unit 70, the weight sensor 80, the temperature sensor ( 90) and the controller 110.

The transparent planar heat generating cover 40 has been described in detail with reference to FIGS. 2 and 3, and the description thereof will be omitted here for simplicity.

The power supply unit 60 is a component for supplying electrical energy to the transparent planar heat generating cover 40, and a commercial power source, a fuel cell, and the like may correspond thereto. In general, considering that the greenhouse is installed in a place where a lot of sunlight can be received, installing a solar cell around the greenhouse and using it as part of the power supply unit 60 will be very effective in terms of energy efficiency. In addition, a rotary blade for wind power generation is installed around the greenhouse, and electrical energy generated as the rotary blade rotates may be used as the power supply unit 60. The use of such eco-friendly renewable energy increases energy efficiency and prevents the generation of pollutants. This is because, in case of heavy snow, strong winds are often accompanied, and thus generating electric energy using such a strong wind helps energy efficiency.

The communication unit 70 is a component for communicating with an external server. In the present invention, the communication unit 70 is a component for acquiring external weather information (ie, snowfall or information on outside temperature). That is, when the information on the outside temperature and heavy snow is obtained, the controller 110 heats the planar heat generating cover 40 in advance, thereby preventing the snow from accumulating in the greenhouse in advance.

As the communication unit 70, a wireless internet module, a wired internet module, a short range communication module, or the like may be used.

The weight sensor 80 is a component for measuring the weight of snow that is installed on the ceiling or the upper side of the greenhouse 100, and may be installed on the ceiling or the upper side of the greenhouse 100.

The control unit 110 to be described later controls the power supply unit 60 so that the transparent surface heating cover 40 generates heat when the weight of the eye measured from the weight sensor 80 is greater than the reference weight. Then, the snow melts and flows down, and accordingly, the weight of snow that presses the frame or the cover of the greenhouse is reduced, so that the greenhouse is not damaged.

At this time, the controller 110 may control the degree of heat generation of the transparent planar heating cover 40 based on the weight of the eye measured by the weight sensor 80. That is, when the weight of the eye increases, the heating amount is increased, and when the weight of the eye decreases, the power supply unit can be controlled to lower the amount of heating. That is, the energy consumption efficiency can be improved by controlling the degree of heat generation according to the amount of snow.

In addition, when the weight from the weight sensor 80 is less than a predetermined amount within a predetermined time, the power supply unit 60 may be controlled so that the transparent surface heat generating cover does not generate heat. That is, when the snow melts, it becomes water, and when water flows down the slope of the greenhouse, the other snow flows down by the tension of the water. Then, the weight of the eye measured by the weight sensor 80 is suddenly reduced. Then, it is no longer necessary to heat the surface heat generating cover. By this operation, energy consumption can be reduced.

The temperature sensor 90 measures the temperature outside the greenhouse 100. As the outside temperature is lowered, more energy is required to melt the snow. In consideration of this, the controller 110 controls the degree of heat generation of the transparent planar heat generating cover based on the temperature measured by the temperature sensor 90. The temperature sensor 90 may be installed on the ceiling of the greenhouse, or may be installed on the ground around the greenhouse.

The control unit 110 controls the power supply unit 60, the communication unit 70, the weight sensor 80, and the temperature sensor 90 as described above to remove the snow accumulated in the greenhouse 100. A function of controlling the heat generation degree of (40).

Since the functions of the controller 110 have been described in the description of each component, description thereof will be omitted for simplicity.

5 is a perspective view of a greenhouse having a snow removal function according to another embodiment of the present invention. As shown in Fig. 5, when two greenhouses (the vinyl house 100 are adjacent to each other, a transparent planar heating cover 40 'may be installed on the ground.) Then, the ceiling surfaces of the two greenhouses. Snow dropped to the ground by the heat cover 40 installed in the back can be completely dissolved by the surface heat cover 40 'of the ground, so that a user such as a farmer does not have to make an effort to clear the snow. do. .

According to the greenhouse having a snow removal function having the above-described configuration, the snow accumulated on the ceiling (top) of the greenhouse can not only be melted as a cotton by the transparent planar heating cover, but also the remaining snow can be removed at once using the tension of water. As a result, a large amount of snow can be removed at once.

In addition, according to an embodiment of the present invention, by acquiring the weather information in advance through the communication unit it can prevent the snow from accumulating in the plastic house in advance.

In addition, according to one embodiment of the present invention, since the degree of heat generation can be appropriately controlled using the weight sensor and the temperature sensor, it is possible to increase the thermal efficiency and to appropriately consume the energy. In addition, by using eco-friendly renewable energy such as solar cells or wind energy as a power supply, eco-friendly energy consumption can be reduced.

In addition, the transparent heating cover according to an embodiment of the present invention can maintain the greenhouse effect in terms of maintaining the light transmittance of the light as it is.

The greenhouse having the snow removal function described above may not be limitedly applied to the configuration and method of the above-described embodiments, but the embodiments may be selectively or partially all of the embodiments so that various modifications may be made. It may be configured in combination.
