In general, the cultivation of vegetables such as vegetables, fruit trees, and flowers in facilities such as vinyl houses and glass greenhouses (hereinafter referred to as "houses") is referred to as facility cultivation. Facility cultivation artificially creates the best environment for growing crops It is well known that crops that are far superior to the main crops are produced and sold within a short period of time, so that they can obtain maximum benefits and enable cultivation throughout the year.

However, maintaining the necessary temperature for crops is the most important factor in winter plant cultivation. If the price of oil increases, the heating cost burden is increased. In order to solve the problem of the heating cost burden, recently, a method of growing water by using ground water which raises the temperature in the house by spraying the ground water which maintains a temperature of about 15 ° C / year inside the house in winter is utilized.

However, in the conventional method of using the groundwater using the groundwater, since the groundwater used is discarded through the waterway, the groundwater level of the groundwater is lowered due to excessive pumping of the groundwater for a long time, Therefore, it is necessary to form an underground water hole in another place or to form a deep depth of the ground water hole.

In order to solve this problem, Korean Patent No. 10-0888039 discloses a circulation method of circulating ground water by constituting a reducing water path for returning the ground water drained from the house back to the ground water ball, and a purifying means for purifying the ground water directed to the reducing water path A water film growing system capable of culturing a water film is disclosed.

However, such a conventional water film growing system has a problem in that it requires a lot of installation cost and maintenance cost because of its complicated structure, and since the ground water temperature is low, the water is mixed with raw water or heated by a boiler There is a problem in that the facility maintenance cost is further increased since the waste water is heated and then recycled.

In order to solve the above-mentioned problems, according to the prior art document No. 10-1640523 entitled " Groundwater circulating water film growing system and its operation method ", as shown in FIG. 1, A motor pump 10 installed in the interior of the tube W extending from the inside to the upper side and pumping groundwater; and a motor pump 10 connected to the motor pump 10 and extending upwardly through the inside of the tube W Water supply lines 21 and 22 extending to the roof surface of the house H for guiding the groundwater pumped by the motor pump 10 to the roof surface of the house H, A recovery line 30 disposed at the bottom of the house W and having the other end disposed in the vessel W for recovering groundwater dropped on the bottom surface of the house H and guiding and discharging the groundwater to the vessel W, W of the rock layer R, (50) for guiding groundwater falling downward in the trench (W) to the inner surface of the rock layer (R) after being recovered by the rock layer (30), and the dispersion flap (50) And a cone shape in which the diameter increases from the upper part to the lower part of the water supply line 21 and 22, .

According to this document, the groundwater supplied to and used by the house is recovered again, and the recovered groundwater is heat-exchanged through the outer surface of the water supply line and the inner surface of the rock layer in order to recover the temperature of the recovered groundwater, Lt; / RTI > Therefore, it is possible to circulate the groundwater while keeping the temperature of the groundwater constant without using a separate heating device such as a boiler or an electric heater.

However, the above-described conventional techniques are difficult to actively cope with seasonal or climatic changes. In particular, in order to cope with problems such as the amount or condition of groundwater (temperature, pressure, water level, There is a disadvantage in that no concrete method for circulating the air is provided.

The following terms are defined in consideration of the functions in the embodiments of the present invention, which may vary depending on the intention of the user, the intention or the custom of the operator. Therefore, the definition should be based on the contents throughout this specification.

Prior to the description of the present disclosure, it is to be understood that the general technical constructions commonly used in the fields to which the technology belongs, such as ground water, rock mass, vinyl house, double ply, circulation, water film cultivation, The detailed description of the operation, effect and the like will be omitted.

2 is a groundwater circulating water film growing system according to an embodiment of the present disclosure;

2, in order to raise and maintain the temperature in the greenhouse, the groundwater circulating water film growing system according to the embodiment of the present disclosure is designed to heat the ground water supplied on the roof surface of the greenhouse of the double- A water supply line (200), a collection line (300), an induction member (400), a water supply line (300), and an induction member (400) A dispersion flap 500, a sensor unit 700, and a control unit 800. [0041] Such a groundwater recirculating water film growing system according to an embodiment of the present disclosure is similar to the conventional groundwater recirculating water film growing system shown in FIG. 1 except for a few components, And is used in conformity with the reference numerals shown in Fig.

The motor pump 100 is installed inside the foundation W extending from the inside of the underground rock layer R to the ground to pumped groundwater. The motor pump 100 may be any conventional motor pump commonly used in the field of water film growing system of a vinyl house to which the present disclosure belongs. However, the present invention is not limited thereto. May be used.

In this case, the well W is vertically installed from the inside to the upper side of the rock layer R, and the casing casing C is installed just above the rock layer R. Further, it is preferable that an openable / closable lid is provided at the upper end of the well (W). The rock layer R of the trench W maintains a constant temperature of about 15 캜 to 17 캜 and a groundwater temperature in the rock layer R of about 16 캜.

The water supply line 200 is connected to the motor pump 100 and is installed on the roof surface of the double structure house H extending along the foundation W and provided on the ground at least one way, To the house (H).

The water supply line 200 is connected to the motor pump 100 at a lower end and connected to the upper end of the pumping water pipe 21 at one end thereof, And a supply pipe 22 provided adjacent to the roof surface of the house H and guiding groundwater pumped through the pumping pipe 21 to the roof surface of the house H. [

2, the groundwater is simultaneously supplied to each of the roof surfaces of the three-house house H. However, the number of the ground water is not limited to three or less, It is of course possible to make groundwater equivalent to water. In the present disclosure, groundwater is supplied from the upper side to the both sides of each house H, but is supplied through one pipe from the most convex upper side of the house H, It is obvious to those skilled in the art that the piping can be arranged so as to be spaced apart and supplied over the entire surface of the house, and various modifications can be made through design changes. The transmission line 200 of the present disclosure is shown and described as being installed only on the front (rear) corresponding to the front (or rear) of the house H as shown in FIG. 2, It is to be understood that a person skilled in the art can easily understand that the installation of the water supply line 200 with respect to the house H is described in order to make it clearer and extended with respect to the longitudinal direction of each house H. [ There will be. Through the above description, the house H of the present disclosure can be economically and efficiently controlled by controlling three motors through one motor pump 100.

The recovery line 300 is installed on the bottom surface of the house H and collects the ground water dropped on the bottom surface of the house H and filters the collected ground water through the filter unit 600 provided with the valve 610 (W).

The recovery line 300 is connected at one end to both sides of the bottom surface of the house H and connected to a collection container (not shown) for collecting the ground water dropped on the outer surface of the house H, The groundwater is drawn to the outside of the upper end of the water pipe (21) inside the cannula (W) and guided to the outer surface of the water pipe (21). The collecting cans in the recovery line 300 of the present disclosure as described above have a function and a role largely different from those of the collecting cask 70 shown in Fig. 1, so a detailed description thereof will be omitted. The recovery line 300 may be provided with a filter unit 600 for purifying the recovered groundwater.

Here, FIG. 6 is a view showing an example of the configuration of the filter unit shown in FIG.

Referring to FIG. 6, the filter unit 600 includes a housing, a valve 610, and a filter 620.

The housing is installed at a predetermined position of the collection line 300, and groundwater is collected. Although the housing is shown in a hexagonal shape having a rectangular cross section, it is not limited thereto and may be formed in any shape and various materials that can be collected through the collection line 300.

The valve 610 is installed inside the housing to selectively supply groundwater to the housing. The valve 610 is preferably a butterfly valve that selectively supplies the groundwater supplied to the recovery line 300 through the control of the control unit 800, which will be described later. The valve 610 of the present disclosure has a simple operation of opening and closing the valve body by adjusting the flow rate of the pipe by turning the valve body in the shape of a disk in the valve tube so that the operation is quick and not only for low pressure but also for high pressure water, It is preferable that a widely used butterfly valve be used. However, in the present disclosure, it is preferable to use an automatic butterfly valve instead of a manual lever or gear type, but it is preferable to provide an actuator and a position sensor so that the automatic butterfly valve is automatically controlled through a control unit 800 described later. The configuration of the valve 610 corresponds to a portion of the valve 610 that can be used by a person skilled in the art to variously adapt to the purpose of use through a design change.

The filter 620 is installed inside the housing and purifies the groundwater supplied through the valve 610 through filtering. It is noted that the filter 620 of the present disclosure is preferably but not limited to a triple carbon filter and is also shown mounted longitudinally inside the housing as shown in Figure 6, 610 may be positioned in the lateral direction. As described above, the filter 620 of the present disclosure filters and discharges the groundwater to the ground when the groundwater is insufficient. In particular, the filter 620 of the present disclosure lowers the contamination of the groundwater so that the electrical conductivity can be lowered.

3 is an enlarged view of the portion A shown in Fig. 2, and Fig. 4 is a partially enlarged view of Fig.

As shown in FIGS. 3 and 4, the induction member 400 is connected to the upper end of the pumping water pipe 21 by the groundwater discharged through the collecting line 300 at the lower part of the collecting line 300 connected to the outside, And is guided to the outer surface of the pipe (61). The guide member 400 may be in the form of a funnel whose upper end is attached to the inner surface of the canal W and whose lower diameter is smaller than the upper diameter. At this time, a plurality of guide ribs 410 spaced along the inner circumferential surface of the guide member 400 and formed to stand in the longitudinal direction of the guide member 400 are formed, Even if the amount of the groundwater introduced to the upper side of the guide member 400 having a funnel shape is large, it can be smoothly discharged and supported so that the state attached to the inner surface of the tube W is not twisted. In this case, it is preferable that the upper side of the guide member 400 is extended and protruded in the lateral direction to prevent the guide member 400 from falling down to the lower portion of the rock layer R as shown in FIG. to be.

5 is an enlarged view of a portion B shown in Fig.

The dispersion flap 500 is installed inside the upper tank W of the rock layer R and guides the groundwater recovered through the recovery line 300 to the inner surface of the rock layer R. [

5, the dispersed flap 500 is installed on the upper part of the rock layer R in the vessel W to distribute the groundwater flowing down the outer surface of the water pipe 21 outwardly to form a rock layer R to the inside surface.

Here, the dispersion flap 500 of the present disclosure has a large function and role as the conventional dispersion flap 50 shown in Fig. In other words, the dispersion flap 500 may be formed in a cone shape in which the diameter of the dispersion flap 500 is increased from the upper portion to the lower portion by being fixedly fitted to the outer surface of the water pipe 21 at the upper inlet portion of the rock layer R . The lower end portion of the dispersion flap 500 is disposed adjacent to the inner surface of the rock layer R and flows along the outer surface of the dispersion flap 500 The water is discharged through the lower end of the dispersion flap 500 and guided to the inner surface of the rock layer R and flows down. In particular, as shown in FIG. 5, the lower portion of the dispersed flap 500 of the present disclosure has a predetermined diameter and is extended and protruded toward the lower portion. This is because water flowing down along the outer surface of the dispersed flap 500 R, the water flowing along the rock layer R is stably guided so that sufficient heat exchange can be performed.

FIG. 7 is a conceptual diagram showing the operation principle of the groundwater circulating water film growing system of the present disclosure shown in FIG. 2.

The sensor unit 700 is installed inside the well W having the motor pump 100 and detects the state of the groundwater supplied through the dispersion flap 500.

Referring to FIGS. 2 and 7, the sensor unit 700 includes at least one of a temperature sensor, a pressure sensor, an electric conductivity sensor, and a pH sensor. The temperature, pressure, So that the valve 610 is controlled through the control unit 800 in accordance with the change of the groundwater condition.

In the sensor unit 700, the temperature sensor measures the water temperature of the groundwater sent and received, and the pressure sensor measures the pressure of the water supply line 200 in order to determine the momentary magnitude of the ground water supply amount. Since the electric conductivity is increased when the pollution is large, the state of the groundwater is transmitted to the control unit 800 in real time by measuring the degree of contamination by the electric conductivity. Of course, in order to efficiently operate and manage the groundwater circulating water film growing system of the present disclosure, it is possible to use various sensors such as a pH sensor in addition to the sensors described above, such as measuring the water level or measuring PH, to be.

The control unit 800 controls the operation of the valve 610 in accordance with the change of the ground water measured through the sensor unit 700, thereby controlling the groundwater supply. The control unit 800 may include a display unit for visually displaying the state of the ground water, normal operation of the facility, and a malfunction for the convenience of the user, and a control panel for the control. The display unit and the control panel may be variously implemented for the sake of convenience of the user, so a detailed description thereof will be omitted.

The control unit 800 controls the operation of the valve 610 by receiving a data signal sensed by a sensor unit 700 including a pressure sensor, a temperature sensor, an electric conductivity sensor, and a pH sensor. The case where the unit 700 is a temperature sensor and the case where it is an electric conductivity sensor will be described as follows.

If the temperature of the water intake is lower than 10 ° C through the sensor unit 700, the valve is turned off. If the temperature is higher than 10 ° C, the valve is turned on. The valve is turned off when the electric conductivity is higher than a predetermined value, and turned on when the electric conductivity is lower than a predetermined value.

Of course, it is possible to operate or stop the operation of the valve 610 as in the above-described method, but it is needless to say that the supply amount of the groundwater can be controlled by adjusting the output or the like in some cases. The control unit 800 of the present disclosure as described above can interlock the valve 610 of the filter unit 600 as well as the motor pump 100 as shown in FIG. Particularly, the control unit 800 of the present disclosure performs automatic control for opening and closing the valve 610 of the installed filter unit 600 of the recovery line 300, so that the state of the recovered water can not be maintained at an appropriate temperature (Not shown) installed in the recovery line 300 without supplying the cleaning liquid to the water supply line 200, and the like, and the water is supplied through the motor pump 100 It is possible to supply the ground water only at the proper temperature so that the temperature of the water to be introduced is recovered to the proper temperature more quickly. Although the above-described example is described only with respect to temperature, all the groundwater that is detected from the pressure sensor, the electric conductivity sensor, the PH sensor, and the like is adhered to the state change such as temperature, pressure, water level, Those skilled in the art will understand that the present invention is not limited to those described above.

Meanwhile, the control unit 800 of the present disclosure is fixedly installed as shown in the drawing, but it can be manufactured as a mobile type, and both a wired or wireless coupling scheme can be used. Of course, as shown in FIG. 8, a wireless technology such as Bluetooth, Wi-Fi, or the like may be combined and the sensor unit 700 and the control unit 800 may be interlocked with a user's portable device as an application, thereby maximizing the convenience of use This is a matter of course because it is easy for a person with ordinary knowledge to easily integrate and implement it, so a detailed description will be omitted.

The above groundwater recirculating water film growing system recovers the groundwater supplied to the house and recovers the used groundwater so that the recovered groundwater exchanges heat with the outer surface of the water supply line and the inner surface of the rock layer in turn, Can be maintained at a temperature similar to the temperature of the supplied groundwater and can be circulated while maintaining the groundwater temperature at a constant temperature so as to minimize heat loss without using a separate heating device such as a boiler or an electric heater. (Temperature, pressure, water level, and electrical conductivity due to contamination) in accordance with the temperature change of the groundwater caused by the change of the groundwater temperature, the temperature, the pressure , Water level, pollution degree, etc., can be checked in real time, So that the convenience of the user is increased.

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It is not limited to the embodiment.
