Description

Integrated hydroponic cultivation platform {Integrated hydroponic cultivation platform}

The present invention relates to a hydroponic cultivation platform, and more particularly, to an integrated hydroponic cultivation platform formed so that various hydroponic methods can be used as one hydroponic cultivation platform.

In general, as a method of growing plants with water and nutrient solution, hydroponics have been developed in various forms. There are various methods that can be applied to plants according to the type and size of the hydroponic method, such as distillation, thin film, tidal, drip, wick, steam (water mist), and fish farming. Depending on the operation method, there is also a combination type that combines two hydroponic methods.

There is an optimal hydroponic method applied according to the type and size of plants, because it is necessary to adjust the degree of exposure of roots and stems to water according to the ecology and size of plants. In other words, water must be managed so that the roots and stems do not have too much or too little.

Recently, a wall recording device using a hydroponic method has been introduced for indoor wall greening of houses or buildings. It is used for purposes such as plant wall interior, air purification, and plant cultivation. Most of these devices are widely used in three types: immersion type, drip type, and spray type, and the applied hydroponic method is manufactured, operated, and sold in a fixed form in one way.

As described above, since only one hydroponic cultivation method is determined in the initial installation of the wall greening device fixed to one hydroponic method, only plants of a limited size can be planted. This means that the cause of mortality always exists from the plant's point of view, and because of this, only plants that have grown to a certain size can be planted, which causes a very difficult problem to manage indoor wall greening facilities. In addition, plants applied to indoor wall greening facilities are limited, so various plants cannot be applied. That is, the type of plant and the size of the planted plant are limited according to the facility.

In addition, in the conventional technology, since one hydroponic method is determined at the initial installation of not only indoor wall greening facilities but also cultivation facilities, it is difficult to change depending on the change of plant species or condition, and plants are installed in the initially installed device. It's just a way to adapt. That is, the conventional fixed cultivation method is a human-centered hydroponic plant device, which has a high possibility of plant mortality, low selectivity according to the species and condition of the plant, and in the case of a cultivation facility, there is a work such as transplantation. In addition, in the case of indoor wall greening facilities, there is a problem in that plant species are not diverse because they follow the initially determined hydroponic method.

2 is a view schematically showing a cross-sectional side view of a hydroponic cultivation pipe.

Referring to FIGS. 1 and 2 , hydroponic culture tubes 20 are arranged in a multi-layered structure in the case 10 . The hydroponic cultivation tube 20 is positioned in a mounted state of the plant to be cultivated to form a growing space. The hydroponic cultivation tube 20 extends in the transverse direction and is formed in a tube shape capable of accommodating water therein. The hydroponic cultivation pipe 20 may have various cross-sectional shapes, and for example, the cross-sectional shape may be circular or polygonal.

A plurality of hydroponic culture tubes 20 are provided and arranged in a height direction while forming a layer.

An insertion port 21 into which hydroponic plants are inserted is formed at the front of the hydroponic cultivation pipe 20, and the insertion port 21 is formed so that the user can easily insert or take out the hydroponic plants. A plurality of insertion ports 21 are formed in the hydroponic culture tube 20 of one layer. However, the present invention is not limited by the number of insertion holes 21.

As shown in Figure 2, the insertion hole 21 is formed so that the hydroponic plants are inserted and supported in an inclined form. The insertion hole 21 may be formed so that the hydroponic plant 2 is inserted in an inclined form at an angle of 15 to 45 °. The insertion hole 21 may have a guide inside so that the hydroponic plant can be stably mounted in an inclined state.

Since the hydroponic plants 2 are inclined at each insertion port 21 of the hydroponic culture tubes 20, plant growth is not hindered between the multi-layered hydroponic culture tubes 20. That is, the growth of hydroponically grown plants in the hydroponic culture tubes 20 on the lower layer is minimized from being interfered with by the arrangement of the hydroponic culture tubes 20 on the upper layer.

The hydroponic plant 2 is mounted in a planted state in a pot 3 for hydroponic cultivation in which a root is fixed. Pots for hydroponic cultivation (3) include those of various types in which the roots of the hydroponic plants (2) can be fixed, and do not necessarily have to be tubular pots. A plurality of holes are formed on the side of the hydroponic cultivation pot 3 so that water provided in the form of filling, dripping, or spraying inside the hydroponic cultivation pipe 20 can be smoothly supplied to the roots.

3 is a view showing the arrangement of the hydroponic cultivation tube 20 in the hydroponic cultivation platform according to the present invention.

Referring to FIG. 3 , the hydroponic culture tube 20 may be inclined. Since the hydroponic cultivation pipe 20 has an inclination gradient from one end to the other end, water supplied to one end of the hydroponic cultivation pipe 20 flows to the other end along the inclination gradient.

According to an embodiment of the present invention, the two hydroponic culture tubes 20a and 20b adjacent in the height direction may be disposed inclined in opposite directions to each other. In the present specification, reference numeral 20 represents a hydroponic culture tube, and reference numerals 20a and 20b are used when it is necessary to separately classify and describe a plurality of hydroponic culture tubes 20.

As shown in FIG. 3, the first hydroponic culture pipe 20a constituting the upper layer has a high left end 22a and a low slope of the right end 22b, and is positioned lower than the first hydroponic culture pipe 20a to form the lower layer. The second hydroponic culture tube 20b disposed in has a high right end 22b and a low left end 22a.

The inclination gradient of the hydroponic cultivation pipe 20 is enough to allow water to flow by gravity and is not limited by the inclination angle. When the hydroponic cultivation pipe 20 has an inclination gradient, the side disposed at a relatively high position is referred to as an upstream side, and the side disposed at a relatively low position is referred to as a downstream side. Water flows from the upstream side to the downstream side due to the gradient of the hydroponic culture tube 20 . Therefore, when water flows from one end to the other end by a gradient in the hydroponic cultivation pipe 20, one end may be referred to as an upstream side and the other end may be referred to as a downstream side. 3, in the first hydroponic culture pipe 20a, the left end 22a is the upstream side and the right end 22b is the downstream side, and in the second hydroponic culture pipe 20b, the right end 22b is the upstream side. , and the left end 22a becomes the upstream side.

The downstream side of the first hydroponic cultivation pipe 20a and the upstream side of the second hydroponic cultivation pipe 20b are connected by a connecting pipe 25 . Thus, water can flow continuously along the direction of gravity.

Due to the tilt direction arrangement of the hydroponic cultivation pipes 20 adjacent to each other in the height direction, compact arrangement of the hydroponic cultivation pipes 20 and minimization of the length of the connecting pipe 25 and smooth flow of water can be induced.

The lowermost hydroponic cultivation pipe 20 is connected to the water tank 80 through a connecting pipe 25. Accordingly, the water supplied from the hydroponic cultivation pipe 20 on the uppermost side from the water tank 80 through the water pipe 30 flows along the hydroponic cultivation pipe 20 and returns to the water tank 80. can form

A damper 26 capable of controlling the flow of water is installed in the connection pipe 25. The damper 26 can control the flow rate by opening and closing the flow of water and adjusting the amount of opening. The dampers 26 may be electronic valves, and may be individually and collectively controlled by the central control unit 100 .

A hydroponic method may be selected by controlling the flow of water through the connecting pipe 25 by the damper 26 . For example, in the case of the submerged hydroponic method, in the hydroponic cultivation tube 20, the roots of the hydroponic plants 2 are immersed in water, and the plants grow. In this case, water is maintained at a high water level in the hydroponic cultivation pipe 20 and the damper 26 allows the water to flow at a constant flow rate. On the other hand, in the case of thin-film hydroponics, the minimum water level is maintained while maintaining a constant flow rate.

In addition, when fish are put in and maintained in the water tank 80, a fish farming type hydroponic method is possible, and when a constant flow rate is maintained and a constant water level is maintained while a wick is inserted, a wick type hydroponic method is possible. In addition, when the damper 26 is operated to periodically adjust the amount of water with a large or small amount of water, a tidal-type hydroponic system is possible.

In addition, water is sprayed from the inside of the hydroponic cultivation tube 20 through the faucet 50 to the roots of the hydroponic plant 20, and the water is not stored in the hydroponic cultivation tube 20 but flows without being stored in the hydroponic cultivation system. do.
