[0001] Hydroponic System Using Ebb Tide Engineering Method [

        The present invention relates to a hydroponic cultivation system using an Ebb tide method, and more particularly, to a hydroponic cultivation system using an Ebb tide method, Ebtide (R) is used to control the tangling of roots to prevent ripening or rot, and to provide optimal conditions for growth of hydroponic plants. Ebb tide) method.

Generally, hydroponic cultivation is one of the plant cultivation methods in which nutrients are supplied from a culture solution which is dissolved at an appropriate ratio, unlike the method in which water and nutrients necessary for the growth of crops are supplied from the soil.

Such hydroponic cultivation can protect plants from various insect pests by supplying a culture solution in which various growth promoting agents and nutrients are diluted and artificially accelerating the growth rate of plants, so that a large amount of yield can be obtained in a short period of time without using harmful pesticides It is widely used at present, and it is installed in plant type cultivation farm as well as home use form.

 On the other hand, in hydroponic cultivation as described above, since roots of hydroponic plants are always immersed in the culture solution, there is a disadvantage in that roots are rotten or rotten or incomplete, and the proposed solution is to discharge the culture liquid at regular intervals, The plant will be able to grow vigorously.

For example, a domestic hydroponic cultivation apparatus of Korean Patent Laid-Open No. 10-2012-0011928 (published on Mar. 02, 2012) has been proposed. With reference to this publication, it is configured to discharge or supply the culture solution stored in the cultivation tank to supply fresh air to the root of the plant. In the course of supplying and discharging the culture fluid, the lower limit level and the upper limit level are discharged to the lower limit level at the time of discharging the culture liquid through the sensor, and at the same time, the upper limit level is supplied at the time of supply. Of course, it is possible to produce the effect of inducing the vigorous growth of plants, such as preventing roots and rotting diseases that may occur due to long time water immersion by supplying air to the roots through the discharge of the culture liquid as described above. However, as the supply and discharge of the medium from the supply and discharge of the medium to the upper limit level or the lower limit level are performed at the same time, waving phenomenon occurs and the fingers extending to the water are frequently tangled with each other. When the root roots are tangled with each other, the absorption of the culture fluid is not smooth and the growth of the plant is not strong.

FIG. 2 is a perspective view of an Ebb tide method according to a preferred embodiment of the present invention. FIG. 3 is a block diagram showing a hydroponic cultivation system according to an embodiment of the present invention. FIG. 3 is a cross-sectional view showing an inside of a hydroponic cultivation system using a tide method.

1 to 3, the hydroponic culture system 100 using the Ebb tide method of the present invention includes a main body 110, a cultivation member 120, a culture solution supply member 130, (140) and a controller (150).

On the other hand, Ebb tide refers to the lowering of the water level at low tide, that is, from high tide to low tide. Since the hydroponic cultivation apparatus of the present invention is proposed by considering such phenomenon, it should be recognized that it is called " And may be referred to as an ET method.

The main body 110 is a frame for installing the cultivation member 120, the culture liquid supply member 130, the culture liquid recovery member 140, and the control unit 150, It will be apparent that the present invention is not limited thereto.

Next, the cultivation member 120 is provided on the main body 110, and includes a cultivation tank 122 having a storage space for storing a culture liquid therein, and a cultivating unit 122 disposed above the cultivation tank 122, And a vegetation plate 125 in which a plurality of vegetation holes 126 are formed. At this time, although the shape of the redistribution tank 122 is not limited, the redistribution tank 122 may have a rectangular shape and may be formed as an open top, and an upper jaw 123 may be formed at an upper end thereof to house the vegetation plate 125 .

In addition, a plurality of display units 124 may be formed at one side of the surface of the remirring tank 122 so that the administrator can visually confirm the level of the water. The entire surface of the display unit 124 may be formed of a transparent material, It is also worth considering. At this time, the display unit 124 is formed stepwise in the redistribution tank 122 in accordance with the control of the control unit 150 to be supplied and recovered in at least two stages in the supply and recovery of the culture liquid In order to be able to check the generated water level step by step, this relation will be discussed again below.

The culture solution supply member 130 is disposed below the main body 110 and includes therein a culture solution reservoir 132 for storing the culture solution supplied to the redistribution chamber 122, And a supply pipe 136 for supplying the culture liquid pumped by the supply pump 134 from the upper side of the redistribution tank 122 to the internal storage space, .

Next, the culture solution collecting member 140 includes a recovery tube 142 for recovering the culture solution stored in the lower side of the redistribution tank 122 to the culture solution reservoir 132, Closing valve 144 that is installed in the control valve 150 and opens and closes the conduit. The on-off valve 144 is of a solenoid valve type and is configured to perform opening and closing operations by a control operation of a controller 150 It is natural.

The control unit 150 may be a microcomputer and may be installed at one side of the main body 110 or the cultivation member 120 to control the operation of the supply pump 134 and the opening / The culture medium stored in the culture medium reservoir 132 is pumped to supply the culture medium to the remediation tank 122 to store or store the stored culture medium, thereby controlling the operation of recovering the stored culture medium. At this time, the control unit 150 simply operates the supply pump 134 so that the culture liquid is temporarily stored up to the upper water level of the remiration tank 122 or the opening / closing valve 144 is operated to store the stored culture liquid in the culture tank 122 It is possible to control the supply and recovery of the culture solution step by step at least in two or more stages. That is, when the culture medium is supplied or recovered, it is divided into at least two or more stages and discharged. When the culture medium is divided into two or more stages, it has a time interval before proceeding from the first stage to the second stage. Let's look at it.

The criterion for dividing the supply and discharge steps of the culture liquid may be divided into 4 to 5 steps or more in the second stage depending on the depth of the storage space of the remodeling tank 122. Alternatively, the step may be divided even if the cultivation vessel 122 has the same depth depending on the type of hydroponic plant being cultivated. (A, b, c, d) as shown in FIG. 2, particularly in the case of dividing the water level, as shown in the display 124 displayed on one side of the remodeling tank 122, The display unit 124 provided on the lowermost side indicates the lower limit water level, and the display unit 124 provided on the uppermost level indicates the upper water level. Obviously, the display unit 124 is displayed for the sake of understanding, and it is not necessarily provided.

Feeding and discharging the culture medium by any method. In other words, even if the level of the cultivation tank 122 is divided into stages, the level is gradually increased at intervals of each stage when the culture liquid is supplied, and the level is gradually lowered at each time interval when discharged. This can be realized by a timer signal or a water level detection, that is, a water level detection sensor, as shown in FIG. 3. The operation of the water level detection sensor will be described in detail below.

Hereinafter, the use state of the hydroponic cultivation system using the Ebb tide method of the present invention will be described.

4 is a schematic longitudinal sectional view showing a process of supplying a culture medium of a hydroponic culture system according to a preferred embodiment of the present invention, and "a" and "b" in Fig. 5 are preferred embodiments of the present invention FIG. 1 is a schematic longitudinal sectional view showing a culture solution recovery process of the hydroponic culture system according to the embodiment.

4, the hydroponic plant is planted in the vegetation hole 126 of the cultivating member 120, that is, the vegetation plate 125 placed above the cultivation tank 122, The roots of the cultivation tank 122 extend into the interior of the cultivation tank 122. At this time, the cultivation tank 122 does not store the culture liquid.

In this state, in order to supply nutrients to the hydroponic plants, the culture liquid is supplied through the culture liquid supply member 130 as shown in "B." That is, the control unit 150 operates the supply pump 134 of the culture liquid supply member 130 to pump the culture liquid stored in the culture liquid reservoir 132 and transfer the liquid through the supply pipe 136 to the cultivation tank 122 And the supplied culture liquid will be stored in the remediation tank 122. It is a matter of course that the open / close valve 144 of the culture medium collecting member 140 is set to the closed state. At this time, if the culture liquid stored in the redistribution tank 122 is not stored up to the upper limit level at a time but is stored up to the level of the first stage (a), the control unit 150 stops the operation of the supply pump 134 for a moment a) The supply of the culture medium at a constant interval is stopped until the culture liquid stored at the water level is calm. Then, the control unit 150 restarts the supply pump 134 to supply the culture liquid to the water level of the second stage (b). After stopping the operation of the supply pump 134 again, the supply of the culture liquid is stopped for a certain period of time and then restarted (C) level, and the culture is stored in the same manner up to the upper limit level in step (d) in the same manner. Of course, it is shown that the culture solution is stored in four stages in the figure, but it is clarified that the culture solution is not limited to at least two stages as described above.

As a method for implementing this operation, a first timer-based method can be proposed. That is, when the time required for each culture liquid to be separated in each of the four stages is one minute, the controller 150 supplies the supply pump 134 for one minute and then stops the operation for one minute. It can be preset to operate. Of course, it is obvious that the time setting can be reset or modified by the operator. In this case, the supply of the culture liquid can be performed at a time interval of 1 minute each step.

Second, a method of detecting the water level, that is, a method of detecting the water level by the water level detection sensor, may be proposed. That is, a water level sensor is installed at the upper part of each step, and is implemented by a signal transmitted / received between the control unit 150 and the water level detection sensor. When the water level detection sensor provided in step (a) 150) stops supplying the culture liquid for a set time after stopping the operation of the supply pump 134 and then stops the operation after the water level detection sensor installed in step 2 (b) In such a manner as to have a time interval before proceeding to the next step.

 * Program example *

                06:00:00 - 06:05:05 Water level 15%

                06:07:00 - 06:12:25 Water level 32%

                06:15:30 - 06:18:52 Water level 45%

                06:22:00 - 06:30:30 Water level 70%

                06:37:50 - 06:43:18 Water level 100%

                07:15:00 - 07:18:22 Water level 80%

                07:35:00 - 07:42:30 Water level 38%

                07:49:00 - 07:59:30 Water level 0%

As a result, in the present invention, the culture liquid supplied to the cultivation tank 122, which is adopted in any of the methods, is not supplied to the upper limit level at a time, but the level is divided into at least two levels, It must be recognized.

5, the culture liquid is stored up to the upper limit level of the remiration tank 122, and after a lapse of a predetermined time, the roots of the hydroponic plants are supplied to the culture liquid recovery member 140 The culture solution stored in the remodeling tank 122 is discharged to be recovered to the culture solution reservoir 132. That is, as shown in "B", the control unit 150 opens the opening / closing valve 144 of the culture liquid collecting member 140 so that the culture liquid is recovered through the recovery pipe 142, Like the process of supplying the culture liquid, is to be recovered at a time interval before the water level is lowered in the next step.

That is, when the control unit 150 opens the open / close valve 144 and the culture liquid stored in the step 4 (d) is recovered, the open / close valve 144 is closed, waiting for a set period of time, c). The recovery method is the same as that of the two types of culture solution feeding methods described above, and therefore, a detailed description thereof will be omitted.

As a result, it is possible to prevent the roots of the hydroponic plants from becoming tangled with each other by preventing the ripples that may be generated when the culture liquid is supplied, while inducing the roots of the hydroponic plants to slowly sink into the culture liquid in the course of supplying the culture medium, The root of the hydroponic plant is gradually exposed to the air while the culture liquid is recovered, and at the same time, the ripple phenomenon that may occur when the culture liquid is recovered is minimized, It is possible to provide an optimum condition for the light emitting diode.
