Description

[0001] Plants cultivation apparatus [0002]

The present invention relates to a power plant type planting apparatus that artificially creates an optimized natural environment for plant growth in a designated area to create an environment for plant growth, and to make the environmental composition economical and efficient.

Various kinds of plants can be artificially cultivated for various purposes such as edible, ornamental or experimental. Such artificial cultivation is performed not only outdoors but also indoors, and when artificial cultivation is performed indoors, devices for cultivating the environment are constructed so that the cultivated plants can grow in the same environment as nature.

FIG. 1 is a schematic view showing a conventional artificial cultivation of a plant, and will be described with reference to FIG.

In order to grow plants, one or more shelf fields 10 are provided in a given space H. At this time, a multi-layer shelf may be formed in the shelf 10 so that the shelf can support the container 20 in which the plant 30 is planted. On the other hand, a lighting lamp 41 for illuminating the container 20 located in the lower layer is disposed below the shelf.

As described above, the illumination lamp 41 is a means for providing light for photosynthesis of the plant 30, and typically a discharge lamp such as an incandescent lamp or a fluorescent lamp is used, and a relatively low power consumption fluorescent lamp Widely used. The illumination lamps 41 are turned on and off in cycles corresponding to the sunrise and sunset cycles of the natural system so that the plant 30 can proceed with stable photosynthesis and respiration. As shown in the figure, since the artificial cultivation is for the purpose of cultivating a large amount of plants, a plurality of illumination lights 41 are installed in one of the shelves 10, and the illumination lights 41 are collectively controlled. Accordingly, the shelf 10 can be provided with operation panels 50, 50 ', and 50 "for collectively controlling the lighting and the lighting of the illumination lamp 41. [

Subsequently, the space H may be provided with a humidifier 60 for keeping indoor humidity constant within a predetermined range.

In the space H, a cooling / heating unit 70 may be provided to maintain the room temperature constant within a predetermined range.

In addition, a ventilator 80 for ventilation of the room is provided in the space H, and a piping facility P for exhausting can be constructed.

The lighting lamp 41, the humidifier 60, the air conditioner 70 and the ventilator 80 may be separately operated by the grower or may be collectively controlled by the central controller 90. [

As described above, in order to cultivate the plant 30 in a room, it is necessary to provide a certain environmental condition, and installation and operation of various devices are required for this purpose. However, these devices require constant power consumption, and this power consumption increases the cost of growing the plant (30), thus reducing the final revenue generated by plant (30) cultivation.

Particularly, since the lighting lamp 41 must operate so that the amount of light designated to the plant 30 is continuously supplied according to the type of the plant 30, the lighting lamp 41 is controlled by the central controller 90, do.

As described above, the conventional illumination lamp 41 that illuminates the plant 30 of the container 20 located below the shelf and located below the shelf maintains a constant amount of light irrespective of the state of development of the plant 30 or the like While emitting the set amount of light. However, when the quantity of light is kept constant regardless of the development state of the plant 30, the plant 30 has a disadvantage that excessive light quantity or insufficient quantity of light is supplied to the growth.

In order to solve such a problem, a technique has been developed in which data of the optimized amount of light according to the development state of the plant 30 is collected as data and the brightness of the illumination lamp 41 is adjusted accordingly. However, in order to secure a light quantity suitable for the development state of the plant 30, the above technique must be able to control the brightness of the illumination lamp 41 in a variety of ways, A relatively small number of lighting lamps 41 must be installed in the conventional shelf 30 for the power supply, and a large amount of power must be consumed for driving the lighting lamps 41.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a perspective view showing an embodiment of a plant cultivation apparatus according to the present invention, FIG. 3 is a perspective view showing an embodiment of a lighting stand which is a constitution of a plant cultivation apparatus according to the present invention, do.

The plant cultivation apparatus 100 according to the present invention includes a shelf 110 for forming a space for accommodating plants P and P 'to artificial cultivation (see FIGS. 4 and 5), a lighting stand 130 And an illumination unit 130 for mounting the lamp 136 for generating light. The plant cultivation apparatus 100 may further include a cultivation bed 140 accommodated in the shelf 110 while planting artificial cultivation target plants P and P '. The cultivation bed 140 is a container for planting the plants P and P 'and mounting the plants P and P' on the shelf 110. The cultivation bed 140 comprises a water tank 141 forming a container shape for storing the nutrient solution, , P '), and is mounted on the water tank (141). The cultivation bed 140 may be integrally fixed to the shelf 110, but only the flowerpot 142 may be separated. Also, the entire rearing bed 140 may be separated from the shelf 110.

The shelf field 110 is composed of stationary bases 111a to 111d and seating stands 112a, 112b and 112c for forming a general cube. The embodiment of the shelf field 110 according to the present invention is characterized in that the four axial stands 111a to 111d are arranged at a quadrangle and the three seating stands 112a, 112b and 112c arranged in three layers are arranged in four axial stages 111a To 111d are connected to each other.

The elevator 120 includes a support 121 constituting an outer body of the elevator 120 separately from the shelf 110, a driving part 122 disposed at the upper end of the supporting part 121 to generate a rotational force, And a connecting rod 124 formed on the moving rod 123 so as to move along the moving rod 123 so as to guide the movement of the connecting rod 124 A sensor 125a for sensing the distance between the plants P and P 'planted on the rehabilitation bed 140 and the illuminating stand 130 and transmitting the sensed distance to the driving unit 122; 126b, 126c.

The support 121 is in the form of a separate cube which is separate from the shelf 110 as described above. The support table 121 is separated from the shelf 110 but may be fixed to one point of the shelf 110 so that the shelf 110 and the support 121 are integrated. As a result, the support 121 may have various structures regardless of whether or not the support 121 is separated from the shelf 110 if the structure is installed on the side of the mounts 112a, 112b, and 112c.

On the other hand, a beam 121a is further formed on the upper end of the support 121. The beam 121a allows the support 121 to maintain a constant width, and allows the driving unit 122 to be stably held at a predetermined position. In the embodiment of the present invention, the beam 121a has a tubular shape, holds the width of the support 121, receives the driver 122, and covers the rough outer surface of the driver 122 so as not to be exposed.

The driving unit 122 includes a screw 122a provided from the beam 121a and generates power to rotate the screw 122a. To this end, the driving unit 122 further includes a motor for rotating the screw 122a and a switch for controlling driving of the motor. In addition, the driving unit 122 may further include gears for controlling the number of revolutions of the motor, and may further include arithmetic means for calculating sensed signals received from the plurality of sensors 126a, 126b, and 126c . The description of the calculation means will be made below with the description of the sensors 126a, 126b and 126c.

The switch controls driving and rotating directions of the motor, and controls the rotation and the direction of rotation of the screw 122a.

The moving base 123 includes a nut 123a engaged with the screw 122a. Therefore, the moving base 123 moves in the longitudinal direction of the screw 122a along the rotation direction of the screw 122a, and eventually moves up and down along the installed screw 122a. In the embodiment of the present invention, since the moving table 123 is horizontally disposed above the beam 121a, the moving table 123 moves up and down along the rotation of the screw 122a.

The connecting rod 124 is formed so as to be drawn out below the moving base 123. Since the movable table 123 is located at the upper end of the elevator 120 as described above, the connecting rod 124 to which the illuminating table 130 is fixed should be drawn to the lower side of the movable table 123.

In the embodiment of the present invention, the connecting rod 124 is a rod having a bar shape which can be separated and assembled with the moving rod 123. However, the connecting rod 124 may be a protrusion integrally formed with the connecting rod 124, Or may be a wire.

For reference, when the shelf 110 is a multi-layered structure and the illumination unit 130 is configured for each layer, as shown in the figure, the connection unit 124 combines a plurality of illumination units 130 in a line. Accordingly, since the connecting rod 124 moves along with the movement of the moving rod 123, all the lighting rods 130 fixed to the connecting rod 124 have the same moving distance.

The guide 125 guides the connecting rod 124 moving along the up and down movement of the movable table 123 so that the connecting rod 124 can be moved up and down in the exact position without releasing the guide 125. In the embodiment according to the present invention, 121 so that the link 124 can move along the support 121. The guide 125 may be a tube or an annular shape through which the connecting rod 124 can pass, as shown in the figure, so that the connecting rod 124 always reciprocates up and down to a predetermined position along the guide 125. [ For reference, it is preferable that the guide 125 has a tubular shape having a length enough to cover the connecting rod 124 with a sufficient length so that the connecting rod 124 does not warp in the transverse direction.

FIG. 4 and FIG. 5 are side views sequentially illustrating the operation of the plant cultivation apparatus according to the present invention, and will be described with reference to FIG.

The sensors 126a, 126b and 126c are installed in the illumination stand 130 to sense the distance between the illumination stand 130 and the plants P and P 'in the rearing bed 140 located below. An ultrasonic sensor or a PSD (position sensitive device) sensor may be applied to the sensors 126a, 126b, and 126c for this purpose. The sensors 126a, 126b, and 126c may be disposed at the center of the illuminating stand 130 to efficiently detect the growth state of plants planted throughout the rearing bed 140. However, The distance between the lighting stand 130 and the plant may be detected based on the state of development of plants planted at a specific point,

The sensors 126a, 126b and 126c transmit a sensing signal including information on the distance between the illuminating table 130 and the plant (distance information) to the driving unit 122 so that the driving unit 122 drives .

In the plant cultivation apparatus 100 according to the present invention, since the shelf 110 forms a multilayer (three layers), and the cultivation bed 140 is seated for each of the seating beds 112a, 112b and 112c of each layer, An illuminating stand 130 for illuminating plants planted in the bed 140 is disposed for each layer. Accordingly, the sensors 126a, 126b, and 126c are also provided for each illumination unit 130 of each layer, so that the sensors 126a, 126b, and 126c of the respective layers transmit the sensing signal sensed by the sensors to the driving unit 122, (122) calculates and drives the sensing signals received from the sensors (126a, 126b, 126c) of the respective layers. More specifically, the calculating unit of the driving unit 122 calculates a plurality of sensing signals to derive an average value, and the switch drives the motor according to the average value so that the screw 122a rotates. As a result, the screw 122a rotating in the specific direction by the motor converts the rotary motion into linear motion through the nut 123a, and the moving base 123 moves upward or downward through the nut 123a.

When the average distance (average value) between the illuminating stand 130 and the plants P and P 'is within a set value, the switch drives the motor according to the average value. . As a result, the profile data of the set value is converted into a DB and linked to the driving unit 122 by the type of the plant, and the driving unit 122 drives the motor according to the average value based on the profile data according to the plant species.

As shown in FIG. 4, the plant P cultivated in the cultivation bed 140 is in an initial state of development, and thus has a small height as shown in the figure. Therefore, the lighting stand 130 can be brought close to the plant P to irradiate light. However, when the illuminating table 130 is brought close to the plant P and irradiated with light, a sufficient amount of light can be secured even with a smaller number of power plants than before, and the plant P can be supplied. In other words, the illumination unit 130 can be brought close to the plant P without being distant from the plant P, thereby generating an ideal amount of light for plant P growth even with a minimum number of power plants.

Subsequently, as shown in FIG. 5, the plants P 'cultivated in the cultivation bed 140 have a sufficiently large height as shown, since the development state is middle or late. At this time, the sensors 126a, 126b, and 126c sense the distance between the illuminating table 130 and the plant P ', and the driving unit 122 senses the illuminance based on the sensing signals received from the sensors 126a, 126b, And controls the plant 130 and the plant P 'to maintain a certain distance. Of course, the light emitted from the illumination unit 130 is effectively provided to the plant P ', whereby the power consumed by the illumination unit 130 is efficiently managed.

FIG. 6 is a perspective view illustrating a lighting fixture according to the present invention fixed to a connecting rod. Referring to FIG.

The lighting stand 130 includes a lighting frame 131 formed in a flat plate shape so as to face the re-heating bed 140 and a socket 133 installed in the lighting frame 131 such that the lamp 136 is electrically and mechanically fixed do. The illumination frame 131 is directly connected to the connection block 124. In the embodiment of the present invention, the opening frame 131a is formed at one point of the illumination frame 131 for connection with the connection block 124. [ Since the connecting frame 124 is connected to the vertex portions of the illumination frame 131 in the present embodiment, the opening hole 131a is formed in the center of the illumination frame 131 And may be formed at each vertex portion.

Subsequently, in the embodiment according to the present invention, the opening hole 131a is reinforced so that the tightening bolt 132 penetrates so that the illumination frame 131 can be fixed to one point of the connecting rod 124. [ More specifically, when the connecting rod 124 passes through the opening hole 131a in the longitudinal direction, the tightening bolt 132, which is laterally inserted in the opening hole 131a, presses the connecting rod 124, And is brought into close contact with the inner surface of the hole 131a. As a result, the linkage 124 is brought into close contact with the aperture hole 131a, so that the illumination frame 131 can maintain its current position without further movement. As a result, the illumination frame 131 is movable along the link 124 and can be fixed at a position designated by the tightening bolt 132, so that the fixing position is adjusted according to the type of plant to be planted in the cultivation bed 140 .

The socket 133 is a bar-shaped socket dedicated for the lamp 136, and a pair of mating pairs is disposed inside the illumination frame 131 so as to face each other. For reference, the lamp 136 may be implemented by a variety of light emitting means such as a resistance bulb, a discharge lamp, and an LED. However, since the lamp 136 frequently performs flicker operation and light amount control based on the profile data collected according to the plant growth (the required light amount according to the degree of plant growth, the related information according to the plant size, etc.) Power consumption and usage are relatively large. In addition, since light is provided at a position close to the plants P and P ', the heat applied to the plants P and P' is relatively large. Therefore, it is preferable to use the LED as the lamp 136 for minimizing power consumption and minimizing the heat applied to the plants (P, P ').

FIG. 7 is a plan view showing a lamp installed in an illuminating stand according to the present invention, and will be described with reference to FIG.

The illuminating table 130 according to the present invention further includes an alignment table 134. [ The alignment frame 134 is disposed inside the illumination frame 131, and one pair of sockets of a pair of mating socket 133 is mounted in a line. 7 (b), the alignment frame 134 is fixed to the illumination frame 131 via the adjustment bolt 135, and the alignment frame 134 is fixed to the illumination frame 131 ) Are coordinated with each other. 7 (a), when the lamp 136 is not installed, the alignment bar 134 moves freely. As shown in FIG. 7 (b) The position of the alignment bar 134 is adjusted by adjusting the bolt of the adjustment bolt 135 so that the gap between the pair of opposed sockets 133 is aligned with each other, And is stably installed by the pair of sockets 133. [

The alignment frame 134 allows the lamp 136 to be attached and detached without the need to operate the socket 133 and allows the lamp 136 to be attached to the illumination frame 131 ) To be installed precisely.
