Description

TECHNICAL FIELD [0001] The present invention relates to a vinyl-house snow removing film using a thermally conductive material,

The present invention relates to a film for removing a vinyl house using a thermally conductive material and a system for removing a vinyl house using the same. More particularly, the present invention relates to a film for removing a snow, which includes a heat ray and a heat conductive layer, By using the thermally conductive material to prevent the snow from being piled up on the vinyl house by melting the snow, the vinyl house can be placed with the snow piled up on the top of the vinyl house, And a vinyl house snow removing system using the same.

In general, vinyl houses are semicircular and can maintain the internal temperature constant, so that various crops can be cultivated regardless of season. The semicircular structure of a plastic house has the advantage that when an object is placed on top or side, it is easily rolled down or pushed down by gravity very easily.

By the way, the vinyl house is a pipe made of skeleton and covered with transparent vinyl. In the winter when the snow is heavy, snow is piled up on the roof of the vinyl house, and the plastic house can not bear the weight, . When the vinyl house is broken, the vinyl house is damaged and the vinyl house is rebuilt as well as damaging the crops grown in the vinyl house.

In order to solve such a problem, a snow removal apparatus including a hot line is installed in a plastic house to dissolve snow accumulated in the plastic house to prevent breakage of the plastic house. As a prior art relating to such a snow removal apparatus, a number of techniques have been proposed including a registration office No. 0398927, a registration office No. 0233803, and the like.

As shown in FIG. 1, a conventional snow removal apparatus may have various forms. For example, the apparatus includes a pad 10 covering an upper portion of a greenhouse 10, a power source 14 connected to a predetermined position of the pad 10, A weight sensor 12 for sensing the weight of snow piled on the pad 10 and a heat sensor 11 for sensing the amount of snow over a predetermined amount by the weight sensor 12, And a controller 13 for controlling the power supply 14 to be supplied.

However, such a snow removal apparatus is not uniformly heated because it has to generate heat by arranging a hot wire, and a portion where the line is arranged has a high temperature, a portion that does not generate heat is generated, When a part of the installed hot wire is broken, the entire heating element does not generate heat, the snow removing device covers the entire surface of the green house, and the hot wire for snowing is formed in a meandering shape on the whole surface. If the weight of the apparatus is heavy, there is a danger that the vinyl house may sink, and thus the snow can not be snowed, but the plastic house may be damaged.

In the case where a sheet composed only of general heat lines is installed on the upper part of the vinyl house, the length of the vinyl house becomes longer, so that the thickness of the heat wire becomes considerable in order to obtain a required heat generation amount, , The amount of heat generated in a very narrow area of the hot wire in contact with the vinyl film is high, so that the contact temperature excessively increases, causing damage such as hardening or melting of the vinyl film.

As another example, the patent registration No. 0161051 disclosed in Fig. 2 has been disclosed. The disclosed example of Fig. 2 includes a plurality of arched frames 23 and longitudinal frames 24 that are erected at regular intervals in the longitudinal direction relative to the ground, a transparent cover 25 covering the arched frame 23 and the longitudinal frames 24, (22), a transparent surface heating cover (21) provided on an upper surface or a lower surface of the transparent cover (22), a power supply unit and a power supply unit to control the heating of the surface heating cover The present invention relates to a greenhouse equipped with equipment.

According to the example of FIG. 2, the surface heating cover is made of a carbon nanotube layer. The carbon nanotube has a dual property of a non-conductive or non-conductive material and has a problem in that it is difficult to manufacture and use at a high cost, have. In addition, since the maintenance is not easy and commercialization is difficult, an alternative that can solve this problem is urgently required.

As described above, the present invention has been made in view of all the problems of the prior art, and has been made to solve the above problems, and it is an object of the present invention to provide a snow- The snow film is attached to the upper part of the vinyl house by melting and flowing down the snow to prevent the snow from being piled on the vinyl house so that the vinyl house falls down with the snow piled up on the upper part of the vinyl house, And a vinyl house snow removing system using the thermally conductive material to prevent damages of crops and damage to property of the crops.

Referring to FIG. 3, a film for removing a vinyl house using a thermally conductive material according to an embodiment of the present invention may be installed on the inner top keel pipe of the vinyl house 1, or may be installed on the outer top of the vinyl house 1 When the snow-removing film 100 is used, the snow-removing film 100 is put on the top of the green house 1, and if not used, the snow-removing film 100 can be rolled up and rolled into a circular shape.

4 to 5, a snow removing film 100 according to an embodiment of the present invention includes a sheet 110, a heat conduction layer 120, and a heat ray 130.

Hereinafter, each component will be described.

The sheet 110 is divided into an upper sheet 112 and a lower sheet 111 and has a rectangular shape with a predetermined width. The sheet 110 is formed in a lengthwise direction of the greenhouse 1 and is made of a transparent material.

The upper sheet 112 and the lower sheet 111 should be transparent, and the material thereof is not particularly limited. For example, it is preferable to use PET (polyethylene terephthalate). The reason why PET (polyethylene terephthalate) material is used is because PET (polyethylene terephthalate) itself is strong against ultraviolet rays and transparent, so that it transmits sunlight though it is light and it is not easily torn and easily torn.

The heat conduction layer 120 is divided into an upper thermally conductive layer 122 and a lower thermally conductive layer 121. The upper thermally conductive layer 122 is attached to a lower surface of the upper sheet 112, Is attached to the upper surface of the lower sheet 111, and the upper thermally conductive layer 122 and the lower thermally conductive layer 121 are closely contacted with each other.

The thermally conductive layer 120 has a width of 10-40% based on the width of the sheet 110, and is not particularly limited. And is attached in the longitudinal direction of the sheet 110. The heat conduction layer 120 may be made of aluminum foil, silver foil, copper foil or graphene coated paper which is light and has excellent thermal conductivity, and the material thereof is not particularly limited.

As a material of the heat conduction layer 120, the heat conduction body should be a light conduction-durable and light-durable product as a core part for allowing the heat energy to be transferred to the periphery as quickly as possible.

Among them, the aluminum foil is advantageous in that it does not rust well and has excellent thermal conductivity. Also, since it is light and rigid, it can be installed easily on the vinyl house 1 because the plastic house 1 is not burdened at all and is lightweight.

The thermally conductive layer 120 made of such a material has a characteristic of moving the energy of the heat of the high temperature portion to a low side, and even if the heat is exposed to the cold air in the winter, when the generation of a small amount of heat is started in the heating body, It serves to dissolve snow. If the width of the heat conduction layer 120 is less than 10%, the snow melting area is small and the snow removing effect is poor. If the width of the heat conduction layer 120 exceeds 40%, heat transfer may not be performed well.

The heat ray 130 is thin and light, and its material is not particularly limited. As an example, carbon can be used as a special carbon heating wire coated with insulating material (glass fiber) on the carbon sheath of the raw material. Special carbon hot-wire has heat-resistant, durable, excellent electrical and thermal conductivity, low thermal expansion coefficient, light weight, lubrication, strong reduction at high temperature, low absorption of neutrons and large deceleration capacity. It has a power saving effect and an electromagnetic wave attenuation effect.

The heat ray 130 is longitudinally attached to a central portion between the upper thermally conductive layer 122 and the lower thermally conductive layer 121 and is attached to the lower thermally conductive layer 121 and the upper thermally conductive layer 122 The thickness of the heat ray 130 may be relatively small using the thermally conductive layer 120 so that the entire weight of the heat ray 130 is reduced so that the greenhouse 1 is prevented from falling There is no problem such as collapse or the like, and it can be easily installed or removed on the greenhouse 1.

When the operation of the snow removing film 100 is started in advance before the expected time for snowfall or when the snow is moved in a state of being slightly stacked on the greenhouse 1, the eyes melt on the snow removing film 100 quickly The water is absorbed by the adjacent eye and flows down through the semicircular vinyl. When the water absorbed and absorbed by the adjacent snow is wetted, the surface of the slippery vinyl film and the self-weight increase, . This is the same principle as the avalanche on the mountain. When a minute movement occurs with a partial minimum energy that can move the stacked eye, the gravity force that pulls it moves down, and the snow piled up in a large area around it moves as well, which is the same concept as that of a huge mountain avalanche.

Referring to FIG. 4B, the upper sheet 112, the lower sheet 111, the upper thermally conductive layer 122, and the lower thermally conductive layer 122 of the snow removing film 100 according to an embodiment of the present invention, (121) and the heat ray (130) are formed in a 'C' shape.

4A, the upper sheet 112, the lower sheet 111, the upper thermally conductive layer 122, the lower thermally conductive layer 121, and the heat ray 130 of the snow removing film 100, The melted snow can be flowed down to one side when it is attached to the upper part of the semi-circular greenhouse 1, but the melted snow can flow down to one side by the heat of the heat ray 130. However, So that the heat ray 130 is positioned on both sides of the uppermost portion of the greenhouse 1 so that the snow melted by the heat of the heat ray does not flow down to one side.

The snow removing film 100 according to an embodiment of the present invention may have a connection hole or a through hole that can be connected to the vinyl house 1 at a predetermined position for attachment to the vinyl house 1, . Or a self-adhesive film may be applied to the lower surface of the lower sheet 111 so as to be placed on the outer surface of the vinyl house 1.

6, a vinyl house snow removal system using the snow removal film according to an embodiment of the present invention includes a snow removal film 100, a power supply unit 200, a control unit 400, an eye detection sensor 300, Module 500 as shown in FIG.

Hereinafter, each component will be described.

The snow-removing film 100 is the above-mentioned snow-removing film and its further explanation is omitted.

The power supply unit 200 supplies power to the film 100 for the snow removal to heat the heat ray 130 formed on the snow removal film 100.

The snow detection sensor 300 is installed at the top of the greenhouse 1 to detect whether snow falls. The eye detection sensor 300 may be a reflection type optical sensor or a weight sensor. The eye detection sensor 300 using the reflection type optical sensor has a black plate larger in size than the lower surface of the eye detection sensor 300 on the lower surface of the eye detection sensor 300. When the black plate is installed, when the light is normally exposed, the light is not reflected and does not operate. When the snow accumulates, the light is reflected and the sensor operates. In the case of using the weight sensor, a weight value is set to the sensor, and when the weight accumulates due to accumulation of snow, it is sensed.

The communication module 500 is a part capable of communicating with a control device installed outside, such as a smart phone or a computer.

The control unit 400 is a central command processing unit for receiving and analyzing an external signal and determining whether it operates according to the received signal. The control unit 400 receives power from the power supply unit 200 and controls whether to supply power to the heating wire 130 to be.

The controller 400 includes an automatic power mode 420 and a manual power mode 410. When the controller 400 is set to the automatic power mode 420, The controller 130 may automatically supply the power. In addition, a power supply to the hot wire 130 can be controlled by receiving a signal from the communication module 500. In the manual power mode 410, power can be supplied to the hot wire 130 by operating a power switch.

Also, the control of the controller 400 may be performed through a remote controller, a smart phone, or a computer located outside through the CDMA communication module or the RFID control module.

Next, the operation of the plastic house snow removal system using the snow removal film according to the present invention will be described. Referring to FIG. 7, which is a flowchart of the operation of the plastic house snow removal system using the snow removing film, when the snow detection sensor 300 installed at the top of the greenhouse 1 detects snow, the control unit 400 The controller 400 receives the signal from the eye sensor 300 and analyzes the signal to determine whether the eye sensor 300 operates. The controller 400 is divided into the manual power mode 410 and the automatic power mode 420. When the automatic power mode 420 is set to the automatic power mode 420, And receives power from the power supply unit 200 to supply power to the heating wire 130. In the case of the manual power mode 410, the user confirms that the snow has fallen and directly operates the power switch to supply the power supplied from the power supply unit 200 to the heating wire 130. At this time, the control of the controller 400 may be performed through a remote controller, a smart phone, or a computer located outside through the CDMA communication module or the RFID control module. The heat ray 130 supplied with power from the power supply unit 200 transfers heat to the heat conduction layer 120 and the heat conduction layer 120 maintaining a temperature of 0 degrees or more due to the heat of the heat ray 130 And melts snow accumulated on the snow-removing film (100) on the upper surface of the greenhouse (1). As the snow turns into water, it flows down through the semicircular vinyl house (1). As long as the adjacent snow is wet, the surface of the slippery vinyl film and the self-load increase, and the snow falls down while moving down the semicircular vinyl membrane by the force of gravity. The snow film 100 is installed to melt the snow accumulated in the greenhouse 1, thereby minimizing damage to the greenhouse 1 and damage to crops due to heavy snowfall in winter. In addition, 1), which is suitable for use.
