Description

Snow removal system for vinyl house {system for removing snow of vinyl house}

The present invention relates to a snow removal system for a vinyl house, and more particularly, to a snow removal system for a vinyl house with improved safety as the rate of temperature rise of the self-heating roof pipe is controlled to prevent burning or deformation of the vinyl cover.

Generally, green houses are used to grow various crops such as plants, vegetables and vegetables regardless of season. Such a vinyl house can be easily installed even at low cost, and has high airtightness and warmth, so that it can provide a suitable environment for growing crops.

In detail, the vinyl house includes a pipe assembly installed on the ground to form a skeleton, and a vinyl cover covering the pipe assembly as a whole so that a cultivation space is formed therein. Here, the pipe assembly is typically provided with a galvanized steel pipe coated with a galvanized layer.

However, the pipe assembly has a problem that the galvanized layer is formed relatively thin and easily peeled off during installation or use. As a result, corrosion occurs at the part where the zinc plated layer is peeled off, thereby shortening the life of the product and reducing durability.

On the other hand, when snow is accumulated on the upper part of the plastic house, a person takes a long time because snow has to be swept out of snow by using a broom or a stick. In addition, when snow is excessively piled up due to heavy snow, the upper part of the vinyl house collapses due to the load of snow, which causes serious damage.

In addition, even if the top of the plastic house is not collapsed by the accumulated snow, sunlight is blocked, there is a problem that inhibits the growth of crops grown therein.

Therefore, conventionally, snow removal is performed by separately installing a snow removal apparatus or a heating pad to sweep down snow accumulated while periodically moving on the upper part of the vinyl house.

However, the snow removal apparatus or the heating pad has a problem in that it is inconvenient to use and the installation time is excessively complicated due to the complicated work process for installing the snow pad, and the economic burden is increased due to the installation cost.

Since deformation is prevented, the safety of the product may be further improved.

Second, as the resistance value of the variable resistor unit provided in the inverter module is repeatedly variable, the temperature rise of the loop pipe is repeatedly delayed, so that stable eyes through continuous energizing heat generation within a preset temperature range to prevent burnout or deformation of the vinyl cover.

This is a graph showing the temperature change of the roof pipe over time in the house snow removal system.

1 to 5, the snow removal system 150 for a vinyl house according to an embodiment of the present invention is a loop pipe 11, temperature sensor 50, power supply means 60 and the control unit 70 It is provided including.

Here, the vinyl house snow removing system 150 includes a support frame including the roof pipe 11 and a support pipe 12 having a lower end installed on the ground G to support the lower side of the roof pipe 11. It can be applied to the vinyl house assembly provided with the part (10). At this time, the snow removal system 150 for the vinyl house can selectively control the temperature increase rate during self-heating of the roof pipe 11 to prevent burnout or deformation of the vinyl cover installed to cover the top of the vinyl house assembly. have.

In detail, as shown in Figures 1 to 3, the loop pipe 11 is provided with a plurality of to support the vinyl cover is installed to cover the upper portion is formed of carbon fiber reinforced plastic material but the self-heating through electrical connection The ends of the carbon fibers 11a provided therein are exposed at the ends.

In addition, the loop pipe 11 is preferably provided in a pipe shape having a circular to polygonal cross-sectional profile. Here, the loop pipe 11 includes a plurality of carbon fibers 11a and is formed of carbon fiber reinforced plastic (CFRP) impregnated with resin in the plurality of carbon fibers 11a. .

At this time, the carbon fiber (11a) is characterized by high tensile strength, light weight, low thermal expansion rate, and is used in various industries such as aerospace, automobiles, military, automobiles. In particular, the carbon fiber (11a) has excellent bending rigidity, so that the support strength against the bending load acting by the snow accumulated on the upper part of the vinyl sheet covered by the roof pipe (11) significantly increases the durability of the product further Can be.

Here, the carbon fiber (11a) is electrically connected to the power supply means 60 may be energized heat generated as the power is supplied, the loop pipe 11 by the plurality of carbon fibers (11a) that is energized heat generated Can be heated.

Accordingly, each of the loop pipes 11 may be disposed above the support pipes 12 and may serve as a rafter that covers the upper portion of the roof pipe 11 substantially as the vinyl sheet is covered.

In this case, each of the loop pipes 11 may be disposed to be symmetrical on both sides with respect to the center pipe 13 disposed above the support pipe 12 and spaced apart at predetermined intervals along the front and rear directions.

Here, one end of each of the loop pipe 11 is connected to the center pipe 13, it is preferably disposed to be inclined downward toward the outer side. Through this, when rain or snow melts, moisture may be stably dropped along the inclined surfaces of the vinyl sheets covered on the roof pipes 11 and the central pipes 13.

And, the other end of the loop pipe 11 is preferably coupled to the connecting socket device 20 to be described later. Here, the connection socket device 20 is electrically connected to the power supply means 60 so that the power supplied from the power supply means 60 is energized to the carbon fiber 11a of the loop pipe 11. It plays a role.

On the other hand, the temperature sensor 50 measures the temperature of the loop pipe 11 and transmits a temperature measurement value.

In detail, the temperature sensor 50 may be connected to the outer surface of the roof pipe 11 and measure the temperature of the outer surface of the roof pipe 11 heated by self-heating of the carbon fiber 11a. It may be transmitted to the control unit 70.

In this case, the temperature sensor 50 may continuously transmit the temperature measurement value to the control unit 70. Of course, in some cases, the temperature sensor 50 may transmit the temperature measurement value to the controller 70 at predetermined time intervals, and the use of power according to driving may be minimized to further improve energy efficiency.

In addition, the power supply means 60 is electrically connected to the end of the carbon fiber (11a) exposed on the end side of the roof pipe 11 to remove the snow accumulated on the upper portion of the plastic cover and selectively energized Apply power to heat. Herein, the power supply means 60 preferably includes a power supply unit 61 to which power is applied, and an inverter module 62 to selectively adjust the amount of current supplied from the power supply unit 61.

In this case, the power supply unit 61 may be supplied with power from an external power source. Here, the external power source is preferably understood as a concept encompassing an apparatus for supplying industrial or household power. Of course, in some cases, the power supply unit 61 may be provided as a battery capable of charging power, such as a lithium ion battery.

Here, the power supply unit 61 may supply power to the inverter module 62 according to the driving of a switch unit (not shown) provided separately.

In addition, the inverter module 62 is electrically connected to the power supply unit 61 and is selectively supplied with power according to the driving of the switch unit (not shown). At this time, the inverter module 62 may selectively control the amount of current outputted to be supplied to the loop pipe 11 by the controller 70.

Of course, in some cases, the power supply unit 61 may be controlled to output power to the inverter module 62 when the load measurement value measured by a separate load sensor exceeds a predetermined load reference value. In this case, the load sensor may be mounted on the outer surface of the roof pipe 11 and measure the load of the snow accumulated on the upper portion of the vinyl cover.

On the other hand, the control unit 70 selectively controls the power supply of the power supply means 60 according to the temperature measurement received from the temperature sensor 50 so that the temperature of the loop pipe 11 is adjusted.

Here, as shown in FIG. 6H, when power is continuously supplied to the loop pipe 11 without the inverter module 62, the temperature of the loop pipe 11 rapidly increases with time.

Therefore, there is a problem that burnout or deformation occurs in the vinyl cover by the loop pipe 11 rapidly energized and heated within a short time. In addition, the vinyl cover has a problem in that damage occurs to crops grown inside because the vinyl cover is easily torn around the burned or deformed portion due to the load of snow accumulated thereon.

In order to solve the above problems, the controller 70 controls the inverter module 62 to selectively adjust the amount of current supplied to the loop pipe 11 when the temperature measurement value is within a preset temperature range. Control box is preferred.

In detail, the inverter module 62 preferably includes a variable resistor unit (not shown) having a first resistance value and a second resistance value set to a resistance value different from the first resistance value. In this case, in the present embodiment, the second resistance value is set to have a larger resistance value than the first resistance value, and is illustrated and described by way of example.

Here, when the temperature measurement value is within the preset temperature range, the controller 70 transmits the first gate signal and the second gate signal which are alternately output according to a predetermined cycle to the variable resistor unit (not shown). It is preferable to.

In this case, the first gate signal and the second gate signal may be set to a preset first frequency and a second frequency, and in some cases, may be set to current signals having different polarities (+,-). That is, the first gate signal and the second gate signal may be set to various signals that can control the variable resistor unit (not shown) to vary with each resistance value.

The variable resistor unit (not shown) may be repeatedly variable to the first resistance value and the second resistance value in response to the received first gate signal and the second gate signal.

In detail, the variable resistance unit (not shown) is changed to the first resistance value when the first gate signal is received, and the connection socket device is configured such that the power supplied from the power supply unit 61 has the first resistance value. It is output so that 20 may be supplied. Therefore, when power is output through the variable resistor unit (not shown) which is changed to the first resistance value, the first resistance value is applied to the connection socket device 20 at a first current amount.

When the second gate signal is received, the variable resistor unit (not shown) is changed to the second resistor value, and the connection socket device is configured such that the power supplied from the power supply unit 61 has the second resistor value. It is output so that 20 may be supplied. Therefore, when the power is output through the variable resistor unit (not shown) which is changed to the second resistance value, the second resistance value is applied to the connection socket device 20 at the second current amount.

In this case, since the first gate signal and the second gate signal are alternately received by the variable resistor unit (not shown), the amount of current may be repeatedly adjusted to correspond to each resistance value.

Therefore, it is preferable that the power supply means 60 is repeatedly adjusted the amount of current supplied to the loop pipe 11 according to the resistance value of the variable resistor (not shown) that is repeatedly variable. Here, the power output from the power supply means 60 may be adjusted by varying the current amount repeatedly to correspond to the first current amount and the second current amount.

In detail, referring to FIG. 5, the loop pipe may correspond to a time at which a first gate signal is received, such as a first heat generation section r1 through which power is output from the power supply means 60 to correspond to the first current amount. The temperature of (11) may rise.

In addition, the temperature of the loop pipe 11 may correspond to a time when the second gate signal is received, such as a second heating section r2 through which power is output from the power supply means 60 to correspond to the second current amount. Can rise.

Here, when the second resistance value is set to have a resistance value larger than the first resistance value, the first current amount may be set to a higher current amount than the second current amount. That is, since the power supplied from the power supply unit 61 is set to a predetermined voltage, the amount of current changes when a predetermined resistance value is applied. For example, when the resistance value applied to the power supplied from the power supply unit 61 increases, the amount of current decreases.

Therefore, the temperature rise rate of the roof pipe 11 in the first heat generation section r1 is higher than the second heat generation section r2, and the temperature rise rate is substantially higher in the second heat generation section r2. The temperature rise of the loop pipe 11 may be intermittently delayed. As a result, when the temperature is within the predetermined temperature range, such as the second section s2, the power supplied from the power supply unit 60 to the loop pipe 11 is repeatedly used as the first current amount and the second current amount. When it is variably adjusted, the temperature rise of the loop pipe 11 through the energization heat generation of the carbon fiber 11a may be intermittently delayed repeatedly.

Accordingly, the loop pipe 11 is limited in the rapid temperature rise by controlling the amount of current supplied through the inverter module 60 by the control unit 70 when the temperature during the energization heating is within a preset temperature range. Accordingly, the burnout or deformation of the vinyl cover due to heating in a short time can be prevented, thereby further improving the safety of the product.

Further, as the variable resistor unit (not shown) is repeatedly variable to the first resistance value and the second resistance value, the temperature rise of the loop pipe 11 may be repeatedly delayed. Therefore, since the stable snow can be removed through continuous energizing heat within a predetermined temperature range in which burnout or deformation of the vinyl cover is prevented, snow removal efficiency and safety can be further improved.

In this case, the second resistance value may be set to a larger resistance value than the first resistance value, but may be set such that the amount of current of the power output from the inverter module 62 is substantially close to '0'. Therefore, when the second resistance value is applied to the power supplied from the power supply unit 61, the power supply may be substantially stopped. As a result, when repeatedly changed to the first resistance value and the second resistance value, the power output through the inverter module 62 may be repeatedly supplied and stopped.

On the other hand, the predetermined temperature range is preferably set to 20 ~ 60 ℃. Here, the controller 70 preferably controls to stop the power supply of the power supply means 60 when the temperature measurement exceeds the upper limit value t2 of the preset temperature range.

At this time, when the temperature measurement value measured from the loop pipe 11 exceeds the upper limit value t2 of the preset temperature range, that is, 60 ° C., burnout or deformation of the vinyl cover installed to cover the roof pipe 11 may be performed. There was a problem that there is a risk of fire.

Therefore, referring to FIG. 5, when the temperature measurement value of the loop pipe 11 is measured at the excess temperature t3 exceeding the upper limit value t2 of the preset temperature range, the power supply of the power supply means 60 is supplied. This may be controlled by the controller 70 to stop. At this time, when the power supply of the power supply means 60 is stopped, the heat conduction of the carbon fiber 11a is stopped, so that the temperature of the loop pipe 11 is lowered.

When the temperature measurement value of the loop pipe 11 is measured within the preset temperature range, the inverter module 62 may be controlled such that the resistance value of the variable resistor unit (not shown) is varied.

Therefore, even if the temperature measurement value of the loop pipe 11 intermittently exceeds the upper limit value t2 of the preset temperature range as in the third section s3, the power supply is stopped at each time point exceeding the power supply of the loop pipe 11. Excessive heat generation can be prevented.

Accordingly, the power supply of the power supply means 60 is stopped every time the upper limit value t2 of the preset temperature range is exceeded, so that the temperature rise of the loop pipe 11 due to energization heat is prevented, so that the vinyl cover Burnout, deformation or fire is prevented in advance, which may further improve safety and durability of the product.

In addition, the control unit 70 preferably controls the power supply unit 60 to continuously supply power when the temperature measurement value is less than the lower limit value t1 of the preset temperature range.

At this time, when the temperature measurement value measured from the loop pipe 11 is less than the lower limit value t1 of the preset temperature range, that is, less than 20 ° C., the snow accumulated on the upper portion of the vinyl cover does not melt smoothly and the efficiency of removing snow accumulated thereon. There was a problem of this deterioration.

Therefore, when the temperature measurement value is less than the lower limit value t1 of the preset temperature range, when the power supply means 60 is controlled to supply power continuously by the controller 70 as in the first section s1. The loop pipe 11 may be heated to a temperature higher than or equal to the lower limit t1 of the preset temperature range through energizing heat generation.

In this case, the controller 70 is a resistance value of the variable resistance unit (not shown) is smaller than the first resistance value and the second resistance value when the temperature measurement value is less than the lower limit value (t1) of the predetermined temperature range. It is preferable to control to be changed to either side having a. That is, when the first resistance value is smaller than the second resistance value, the control unit 70 is the variable resistance unit (not shown) when the temperature measurement value is less than the lower limit value t1 of the predetermined temperature range. The state variable to the first resistance value may be controlled to be maintained. To this end, the controller 70 may continuously output the first gate signal and transmit it to the variable resistor unit (not shown).

Accordingly, the variable resistor unit (not shown) is continuously maintained in a state in which the variable value is changed to the first resistance value, and the current amount of power output through the inverter module 62 is set to the first current amount to be continuously supplied. Can be.

Accordingly, when the temperature of the loop pipe 11 is less than the lower limit value t1 of the preset temperature range, the variable resistor unit (not shown) may substantially maximize the temperature increase rate of the loop pipe 11. The state variable with the resistance value can be maintained. Therefore, the rapid conduction heat generation of the carbon fiber (11a) is induced, so even if the snow is rapidly accumulated due to the snowfall in winter can be quickly removed to minimize various damages such as damage to the vinyl cover to the vinyl house assembly. .

On the other hand, the temperature sensor 50 is preferably provided with a plurality to measure the temperature of each of the loop pipe (11). In this case, each of the temperature sensors 50 may be connected to each of the loop pipes 11 to individually measure the respective temperatures. In this case, the plurality of temperature sensors 50 may be connected in signal with the controller 70 to transmit temperature measurement values of the loop pipes 11.

In addition, the power supply means 60 is preferably connected in parallel with each of the loop pipe (11). In detail, the inverter module 62 may be provided in plural so as to correspond to the quantity of each of the loop pipes 11, and each of the inverter modules 62 may be individually connected to the power supply unit 61.

At this time, the control unit 70 preferably controls the power supply of the power supply means 60 so that each of the loop pipes 11 is energized and heated individually. That is, when the power supply means 60 is driven by the switch unit (not shown), the control unit 70 may control the inverter module 62 according to the temperature measurement value of each of the loop pipes 11. have. Therefore, each of the loop pipes 11 may be individually temperature controlled as the resistance value of the variable resistor unit (not shown) of the inverter module 62 connected by the controller 70 is varied.

Accordingly, the plurality of loop pipes 11 may be individually temperature controlled by the controller 70 according to the temperature measurement values measured by the temperature sensor 50 connected to each other. Therefore, even if only part of the snow is accumulated on the upper part of the plastic cover due to various external environments, even if the amount of snow accumulated for each region is different, stable snow can be removed, and thus driving reliability of the product can be further improved.

The predetermined period may be variously set such that the first gate signal and the second gate signal are repeatedly outputted alternately.

Here, the time for outputting the first gate signal and the second gate signal from the controller may be adjusted. That is, the predetermined period is longer when the time for outputting the first gate signal and the second gate signal is longer, and the predetermined period is longer when the time for outputting the first gate signal and the second gate signal is shorter. Becomes shorter. In this case, the rate of temperature increase of the loop pipe 11 may be substantially set in accordance with the predetermined period. For example, the longer the predetermined period is, the lower the rate of temperature rise of the loop pipe 11 may be.

The output time of the second gate signal may be set to vary in response to the temperature of the temperature measurement value. In this case, as the temperature measurement value approaches the upper limit value t2 of the preset temperature range, the output time of the second gate signal may be increased. As a result, when the temperature of the loop pipe 11 approaches the upper limit value t2 of the preset temperature range, as the output time of the second gate signal increases, the temperature rise rate decreases, thereby increasing the upper limit value of the preset temperature range. By continuously maintaining a temperature close to (t2) can be maximized the removal efficiency of the snow accumulated on the top of the vinyl cover, this modification is within the scope of the present invention.

In detail, the power connector 30 preferably includes a socket mounting portion 32 and a plug portion 31, and an outer surface 32a of the socket mounting portion 32 to be electrically connected to the connection socket device 20. It is preferable that a mold is inserted into the power coupling portion 22 so as to be in surface contact with the connection surface 22a. At this time, the socket mounting portion 32 is detachably coupled to the power coupling portion 22 is preferably formed of a carbon material so that the power supplied from the power supply means 60 is energized.

Here, the outer surface 32a of the socket mounting portion 32 is preferably formed of a profile corresponding to the inner surface profile of the power coupling portion 22. In other words, the socket mounting part 32 may be formed as an outer surface profile corresponding to an inner surface profile of any one of a plurality of spaces partitioned by the partition connection part 21a. Through this, the socket mounting portion 32 may be inserted into the power coupling portion 22 and the outer surface 32a may be in surface contact with the connection surface 22a.

At this time, as the socket mounting portion 32 is formed of carbon material, the power introduced from the plug portion 31 is energized, and the outer surface 32a of the socket mounting portion 32 is in surface contact with the connection surface 22a. As the connection socket device 20 can be electrically connected.

In addition, the plug portion 31 is coupled to the socket mounting portion 32, it is preferable that the connection plug of the power supply means 60 is inserted. Here, the plug portion 31 may have one side protruded from the socket mounting portion 32 and the other side may be inserted into and coupled to a plug mounting groove formed on the outer surface 32a of the socket mounting portion 32.

On the other hand, referring to Figure 4, the power supply coupled to the state in which the loop pipe 11 is inserted into the connection insertion portion (23a, 23b) and the power connector 30 is connected to the power supply means (60) ( When it is inserted into the 22, the power supplied through the power supply means 60 is energized to the loop pipe (11).

In detail, the power supplied from the power supply means 60 is energized to the socket mounting portion 32 through the plug portion 31. At this time, since the socket mounting portion 32 is in surface contact with the power coupling portion 22, the energized power is supplied to the connection socket device 20.

Here, the loop pipe 11 is inserted into the connection insertion grooves 24a and 24b so that the ends of the plurality of carbon fibers 11a exposed on the end side contact the conduction contact surface 25c. Therefore, as the ends of the plurality of carbon fibers 11a are in contact with the energizing contact surface 25c, the power supplied to the connection socket device 20 is energized to the plurality of carbon fibers 11a, and the carbon fibers 11a generates heat by energization.

Through this, once the loop pipe 11 is inserted into the connection socket device 20, the snow accumulated on the upper portion of the vinyl sheet by the energization heat of each of the carbon fibers 11a provided therein is the loop pipe ( It is melted by the heat transmitted from the outer surface of 11). Here, since the roof pipes 11 are spaced apart at predetermined intervals along the front and rear directions, the eyes around each of the loop pipes 11 may also be opened due to the heat of moisture in which the snow accumulated on the upper portion of the vinyl sheet melts. Will melt.

Accordingly, even if the roof pipe 11 supporting the vinyl cover is electrically connected even if the loop pipe 11 is inserted into the connection socket device 20 to which power is supplied through the power supply means 30, the self-heating is accumulated on the upper portion. Since snow can be removed, economics and installation convenience can be further improved.

On the other hand, both ends of the support connecting portion 40 are inserted into and coupled to the upper end opening side of the support pipe 12 and the connection insertion portions 23a and 23b, respectively. In detail, the support connecting portion 40 is preferably formed of an engineering plastic material, it is preferable that the insertion protrusion 41 and the insertion limiting portion 42 are provided.

In addition, the insertion protrusion 41 is preferably provided at the upper end and the lower end of the support connecting portion 40, respectively. Here, the insertion protrusion part 41 is preferably formed to have a diameter corresponding to the diameter of the hollow diameter of the support connecting portion 40 to the diameter of the connection insertion groove (24a, 24b).

At this time, the outer surface of the insertion protrusion 41 is spaced apart at predetermined intervals along the circumferential direction so as to be coupled to the opening side of the connecting socket device 20 and the support pipe 12 by a radially outward fitting Is protruded. Through this, when the insertion protrusion 41 is inserted, the fitting protrusion may be pressed against the inner surface of the upper end opening side of the support pipe 12 to the inner surfaces of the connection insertion grooves 24a and 24b to be pressed.

On the other hand, the insertion limiting portion 42 is disposed between each of the insertion protrusions 41 and preferably integrally protrudes radially outward along the outer surface of the support connecting portion (40). That is, each of the insertion protrusions 41 may be disposed to be substantially symmetric in the vertical direction about the insertion limiting portion 42.

Through this, the insertion limiting portion 42 is caught by the upper edge of the support pipe 12 to the opening side edges of the connection insertion grooves 24a and 24b when the insertion protrusions 41 are inserted into the insertion protrusions, respectively. The insertion depth of (41) can be limited.

Accordingly, the support pipe 12 is prevented from being energized from the power supply means by the support connecting portion 40, so that power is supplied only to the loop pipe 11 that requires substantially energized heat generation, thereby preventing unnecessary waste of power. Economics and safety can be further improved.
