Description

  The present invention is a hydroponic water tank that can prevent the root part of a plant from spreading in a flow path and secure a flow path for nutrient solution while ensuring the overall rigidity and can be easily connected using a joint. About.

  In recent years, there is no need to use soil, high-density production is possible in a small indoor space, temperature and humidity can be adjusted without being affected by the weather, and contamination by germs and insects is eliminated. Hydroponic cultivation equipment has been attracting attention because of its many advantages such as being easy to do. The hydroponic cultivation apparatus generally employs a hydroponic cultivation apparatus in which cultivation shelves for growing plants are arranged in multiple stages at a predetermined separation distance in the vertical direction, and a lighting device is provided on the upper side of each hydroponic container. ing.

  The hydroponics apparatus is provided with a long rod-shaped water tank that stores or circulates a nutrient solution that promotes the growth of the plant, and the root of the plant is immersed in the nutrient solution in the aquarium. It promotes plant growth. Some of them have a step inside the water tank to prevent a nutrient solution from circulating (flowing) due to foreign substances entering while preventing the generation of algae (see, for example, Patent Document 1).

JP 2014-82996 A

  However, in the conventional aquarium, there is a problem that the flow of the nutrient solution is obstructed due to the spread of the root part accompanying the growth of the plant, the flow of the nutrient solution is blocked, and overflows to the outside. In addition, since the aquarium is formed in a long shape from the structure of the hydroponic cultivation apparatus, it is required to connect and connect a plurality of joints using joints or the like, but in a conventional aquarium, it is provided inside. Since the step shape has an influence on the shape of the outer peripheral portion, connection using a joint or the like becomes difficult, and handling properties including water leakage and cleanability are reduced.

  Furthermore, since the aquarium is partially supported and fixed in the hydroponic cultivation device, there is a concern about the occurrence of bending, etc., but the conventional aquarium is structurally low in rigidity at the upper part and flexes during use. There was a problem that the nutrient solution flowed in an undesired direction.

  Therefore, the present invention has been created in view of the above problems, and prevents the flow stop of the flow path inside the tank due to the spread of the roots accompanying the growth of the plant to maintain the flow of the nutrient solution, It aims at providing the water tank for hydroponics which can connect simply using a joint, improving the whole rigidity.

In order to solve the above problems, the present invention provides:
It is composed of a long eaves member that has a bottom with a step formed inside,
Providing a protrusion-shaped or hollow-shaped rib on the upper part of the side part,
A water tank for hydroponics is provided.

  In the hydroponic water tank of the present invention having such a configuration, the bottom of the tank formed with a step is provided to prevent water stoppage of the flow path inside the tank due to the spread of the root part accompanying the growth of the plant. In addition, the flowability of the nutrient solution can be maintained. Moreover, since the protrusion-shaped or hollow-shaped rib is provided, the rigidity of the upper part can be ensured, and even a long length can be used stably.

  In the hydroponic water tank of the present invention, it is desirable that the ratio of the lowest first bottom width and the second second bottom width is 70 to 90%.

  In the hydroponic water tank of the present invention having such a configuration, the nutrient solution can be flowed into the first flow path (within the first bottom width) at a predetermined flow rate, and the root of the plant grows to form the first flow path. Even if the weir is stopped, the second channel (within the second bottom width) can be flowed as the channel.

  Moreover, in the water culture tank according to the present invention, it is desirable that the outer peripheral portion is formed in a substantially curved shape.

  In the hydroponic water tank of the present invention having such a configuration, since the outer peripheral part has no step and is formed with a gently curved surface, other hydroponic water tanks can be easily elongated using a joint. Multiple connections can be made in the direction. Moreover, since the contact surface with a joint becomes smooth, generation | occurrence | production of a clearance gap etc. can be suppressed and a water leak can be prevented suitably.

  Moreover, in the water culture tank of the present invention, it is desirable that the water culture tank according to claims 1 to 3 and the joint are integrated.

  In the hydroponic water tank of the present invention having such a configuration, the joint is integrally formed with the hydroponic water tank, thereby reducing the number of parts and improving the handleability, and the hydroponic water tank Extension connection between each other can be performed more easily. In addition, compared to the case where two pipes are connected using a joint prepared separately from the hydroponic tank, the area where the joint and hydroponic tank are in contact with each other is reduced. It can be greatly suppressed. In connection with this, a handleability and cleaning property can also be improved.

  In the hydroponics tank of the present invention, it is desirable that a drain pipe is connected to the joint.

  In the hydroponic water tank of the present invention having such a configuration, the drain pipe does not interfere with the connection of the hydroponic water tank using the joint by connecting the drain pipe to the joint, and is long. Since it can arrange | position at the edge part of a direction, for example, the nutrient solution which flowed down downstream can be transferred effectively. That is, in the conventional aquarium, as a result of being formed with a single trough member, the connection of the drain pipe was limited to the end of the aquarium, but in the aquaculture tank of the present invention, through the joint By connecting the drain pipe, there is no limitation as in the prior art, and the drain pipe can be connected to an arbitrary position in the water tank.

  In the hydroponics tank of the present invention, it is desirable that a sealing material is filled between the hydroponic tank and the joint.

  In the hydroponic water tank of the present invention having such a configuration, the sealing material is filled in the hollow portion formed in the vicinity of the contact surface with the joint and in the cross section, thereby improving the fixing force of the connection portion while leaking water. Can be prevented.

  Moreover, in the water culture tank according to the present invention, it is further desirable that the ratio of length to width is 20: 1 to 300: 1.

  In the hydroponic water tank of the present invention having such a configuration, the nutrient solution can be flowed at a desired flow rate while ensuring the rigidity of the hydroponic water tank.

  According to the present invention, it is easy to use a joint while preventing the water flow of the flow path inside the tank due to the spread of the root part accompanying the growth of the plant and maintaining the flow of the nutrient solution, increasing the overall rigidity. The water tank for hydroponics that can be connected to can be provided.

  Although there is a hollow portion below the second bottom portion, the width and height of the first and second bottom portions are different from the conventional water tank shape for the sake of securing the flow path. Moreover, the side part is formed substantially uniformly vertically, and a large number of water tanks can be efficiently arranged in the hydroponic cultivation apparatus. Further, cleaning is facilitated by forming the inner side surface with a smooth curved surface.

Further, in the following description, the same or corresponding parts are denoted by the same reference numerals, and redundant description may be omitted.

1. Outline of Hydroponics Tank 1 The outline of the hydroponics tank 1 in this embodiment will be described with reference to FIG. Drawing 1 is a mimetic diagram showing an outline of water tank 1 for hydroponics in this embodiment. The main hydroponic tank 1 is a component disposed in a hydroponic cultivation apparatus 101 that reduces various influences such as weather and temperature, and pests, and enables stable cultivation while improving the efficiency of photosynthesis of the plant 51. And it is a water tank which stores or circulates the nutrient solution 53 which promotes the growth of the plant 51 inside.

  Moreover, the water tank 1 for hydroponics of this embodiment can prevent the water stop of the flow path inside a tank resulting from the breadth of the root part 55 accompanying the growth of the plant 51, and can maintain the flowability of the nutrient solution 53. It has the characteristics that can be. Moreover, since it uses long, it has the characteristic which can connect simply using the joint 11 components formed separately or integrally, improving rigidity.

  In addition, the hydroponics apparatus 101 which arrange | positions the water culture tank 1 in this embodiment irradiates light to the structure frame 103 which forms a main body, the vegetation plate 105 holding the plant 51, and the plant 51, for example. The lighting device 107 that promotes photosynthesis, the exhaust fan 109 that exhausts the air in the cultivation area to the outside, the top plate 111 that is disposed on the top of the main body configured by the structural frame 103, and the side plate that is attached to the side portion 113, and the like, and a known configuration can be used. For example, a hydroponic cultivation apparatus shown in JP-A-2017-042009 is preferable.

2. Structure of water culture tank 1 <Cross sectional structure of water culture tank 1>
Next, the structure of the water culture tank 1 according to the present embodiment will be described in detail with reference to FIG. FIG. 2 is a perspective view showing the structure of the hydroponic water tank 1 in the present embodiment. In addition, below, the width direction of the water tank 1 for hydroponics is demonstrated as X, a elongate (length) direction is set to Y, and a height direction is set to Z.

  As shown in FIG. 2, when the cross section perpendicular to the width direction X is viewed from the long direction Y, the hydroponic water tank 1 is a long water tank having a substantially U-shaped (樋 shape) cross section ( A second side portion 19 that is generally a side wall, a first bottom portion 3 that is located at the lowest level, and a second bottom portion 5 that is located above the first bottom portion 3. A first side portion 17 that connects the first bottom portion 3 to the second bottom portion 5 substantially vertically, and a rib 7 that is disposed so as to face each other above both second side portions 19. Is formed.

  More specifically, with respect to the cross-sectional shape of the hydroponic water tank 1 in the present embodiment, the first bottom portion 3 disposed substantially horizontally (substantially parallel to the floor surface 115 on which the hydroponic cultivation apparatus 101 is installed) is provided at the bottom. The first flow path 13 is formed by disposing first side portions 17 erected substantially vertically with respect to the first bottom portion 3 at both ends in the width direction X of the first bottom portion 3. Moreover, the 2nd bottom part 5 extended in the width direction X and the outer side from both the 1st side parts 17 is connected, and this 2nd bottom part 5 is substantially parallel to the 1st bottom part 3 (in other words, substantially parallel to the floor 115). Are arranged to form a step.

  Further, a second side portion 19 erected substantially vertically with respect to the second bottom portion 5 is disposed at the outer end portion in the width direction X of the second bottom portion 5 and extends upwardly, and the second flow path 14. And the protruding ribs 7 facing each other are provided on the substantially uppermost portion. The first bottom part 3, the second bottom part 5, the first side part 17 and the second side part 19 described above are smooth surfaces, and all of them extend in the longitudinal direction Y although they have different angles in cross section.

  Further, the inside of the step formed by the second bottom portion 5 and the first side portion 17 is a hollow portion 21, and the inside of the rib 7 is also a hollow portion 15. These hollow portions 21 and 15 contribute to weight reduction by reducing the weight while improving the rigidity of the entire hydroponic water tank 1 in the present embodiment. Since the water culture tank 1 stores or circulates the nutrient solution 53 inside as described above, if the curve or deflection occurs over the entire length, the nutrient solution 53 flows in an unbalanced or unintended direction, and thus has a predetermined rigidity. Although provision is indispensable, in the hydroponics tank 1 of this embodiment, since it has the step formed with the rib 7 extended in the elongate direction Y, the 2nd bottom part 5, and the 1st side part 17, the said rigidity is provided. It can be suitably secured.

  In addition, it is desirable to determine the overall size within a predetermined range in order to prevent deformation such as bending after the water culture tank 1 for hydroponics has a cross-sectional shape that ensures rigidity as described above. More specifically, the overall size is such that the ratio of the length dimension in the longitudinal direction Y of the water culture tank 1 to the width dimension in the width direction X is in the range of 20: 1 to 300: 1. It is preferable to set.

<Width dimensions of the first bottom 3 and the second bottom 5>
Next, setting of the width dimensions of the first bottom portion 3 and the second bottom portion 5 will be described in detail with reference to FIG. FIG. 3 is a cross-sectional view of the hydroponic water tank 1 in the present embodiment. The first bottom portion 3 and the second bottom portion 5 are preferably formed by setting predetermined widths in the width direction X, respectively. More specifically, the width dimension L1 of the first bottom part 3 (two in contact with the first bottom part 3) with respect to the width dimension L2 of the second bottom part 5 (opposite distance between the second side parts 19 of the two surfaces in contact with the second bottom part 5). It is preferable to set both width dimensions by setting the ratio of the facing distance of the first side portion 17 of the surface to 70% to 90%.

  By setting the width dimension L1 of the first bottom part 3 and the width dimension L2 of the second bottom part 5 at the above ratio, the nutrient solution 53 can be flowed to the first flow path 13 at a predetermined flow rate, and the root part 55 of the plant 51 is obtained. Even if the first channel 13 is dammed up, the second channel 14 can continue to flow.

  As shown in FIG. 3, the hydroponic water tank 1 in the present embodiment is smooth and gently curved with no step on the outer peripheral portion 9. More specifically, it is desirable not to expose the valley of the back surface of the step formed by the first side portion 17 and the second bottom portion 5 as it is, but to cover it with a smooth and gently curved outer wall ( At the same time, the hollow portion 21 is formed). Thereby, the water tank 1 for hydroponics can be easily connected and extended in the elongate direction Y using the coupling 11 mentioned later.

3. Flowing Effect of Hydroponic Cultivation Tank 1 Next, the flowing water effect of the hydroponic cultivation tank 1 in the present embodiment will be described in detail with reference to FIGS. 4 (a) and 4 (b) are views showing the flowing water effect of the hydroponic water tank 1 in the present embodiment. FIG. 4 (a) shows the flow of the nutrient solution 53 using the first flow path 13. FIG. 4B is a schematic diagram showing a state in which the nutrient solution 53 is flowed using the second flow path 14. As described above, the hydroponic water tank 1 has the first flow path 13 formed by the first bottom 3 and the first side 17 and the second flow path formed by the second bottom 5 and the second side 19. 14, the flow of the nutrient solution 53 can be continuously maintained even when water stoppage caused by the root portion 55 of the plant 51 occurs.

  As shown in FIG. 4A, when the plant 51 is vegetated, the root portion 55 gradually hangs downward from the upper side as it grows, and gradually comes into contact with the first bottom portion 3. As the root portion 55 continues to grow, the first bottom portion 3 spreads in the width direction X, but is blocked by the first side portions 17 erected at both ends of the first bottom portion 3 in the width direction X, and temporarily temporarily. Fits within 13. As a result, the root portion 55 of the plant 51 is prevented from spreading beyond the first side portion 17.

  As the plant 51 further grows, the density of the root portion 55 in the first flow path 13 gradually increases, and the flow of the nutrient solution 53 that the first flow path 13 has lost is lost, and the downstream flow is stopped. It falls into the state of stopping water. However, since flowing water from the river continues, the water level of the nutrient solution 53 in the first flow path 13 increases and the water level rises.

  As shown in FIG. 4B, since the first side portion 17 of the first flow path 13 suppresses the spread of the root portion 55, the second side portion 19 and the first side portion 17 (second flow path 14). ) Is a state where a space where water can flow is secured. The nutrient solution 53 that has been stopped by the root portion 55 to increase the water level gets over the upper end of the first side portion 17, reaches the second flow path 14, and flows downstream from the space.

  The hydroponics aquarium 1 of the present embodiment has a two-stage first flow path 13 and a second flow path 14 that are configured vertically with different width dimensions, so that the root 51 of the plant 51 grows along with the growth. The possible range can be forced and the flow of the nutrient solution 53 can be switched according to the situation to maintain the flow. In the present embodiment, as described above, a description is given on behalf of a configuration that includes the two-stage flow path including the first flow path 13 and the second flow path 14. You may comprise and comprise a flow path.

4). Extension of hydroponic water tank 1 using a joint <structure of joint 11>
Next, the structure of the joint 11 used for the water culture tank 1 of the present embodiment will be described in detail with reference to FIG. FIG. 5 is a schematic diagram showing the structure of the joint 11 used in the hydroponic water tank 1 of the present embodiment. A plurality of hydroponics aquariums 1 can be connected to each other by a method similar to a general extension method such as a rain gutter and extended to a desired length.

  Although it is also possible to use a technique in which a joint is formed separately from the hydroponics tank 1 and the joints are connected so as to fix both ends in a state where the end faces of the plurality of hydroponic tanks 1 are abutted. Since it increases and handling property falls, it is desirable to set it as the following aspect which can be connected more simply.

  As shown in FIG. 5, it is preferable that the joint used for the connection of the hydroponic water tank 1 of this embodiment is integrally formed at one end of the hydroponic water tank 1. More specifically, a substantially U-shaped (樋 -shaped) joint 11 that covers (adheres or integrally forms) the outer peripheral portion 9 of one end of the hydroponics water tank 1 is formed, and hydroponics is performed. The receiving part 12 that protrudes in the longitudinal direction Y beyond one end of the water tank 1 is connected while covering the outer peripheral part 9 of the other water culture tank 1 that has been faced.

  In addition, as for the protrusion length dimension of the receiving part 12, it is desirable to determine suitably according to the cross-sectional dimension of the water tank 1 for hydroponics, and the length dimension of the elongate direction Y. Moreover, in this embodiment, although the fixed aspect of the other water culture tank 1 and the coupling 11 is not specified, for example, a locking part (not shown) is provided above the height direction Z of the receiving part 12. It is possible to use a form such as forming and locking and fixing to the rib 7 of the other water culture tank 1.

  By forming the joint 11 integrally with one end of the hydroponics tank 1, the number of parts is reduced to improve handling, and the hydroponics tank 1 can be easily extended and connected. be able to. Moreover, compared with the case where two are connected using a joint prepared separately from the hydroponics tank 1, the area where the joint and the hydroponic tank 1 are in contact with each other is reduced to about half (the joint 11 is formed integrally with one hydroponics tank 1), so that leakage from the vicinity of the joint 11 can be significantly suppressed.

  Further, by filling the hollow portion 15 and the hollow portion 21 formed in the vicinity and cross section of the aquaculture tank 1 and the joint 11 with a sealing material, water leakage can be improved while improving the fixing force of the joint 11. Further, it can be prevented.

<Fitting 211 provided with drain pipe 23>
Subsequently, the structure of the joint 211 provided with the drain pipe 23 will be described in detail with reference to FIGS. 6 (a) and 6 (b) are diagrams showing the structure of the joint 211 provided with the drain pipe 23, and FIG. 6 (a) is a cross-sectional view of the joint 211 cut in the width direction X. 6 (b) is a plan view of the joint 211. In order to promote the growth of the plant 51 more efficiently by circulating the nutrient solution 53, the hydroponic cultivation apparatus 101 is provided with a drain pipe 23 in a predetermined position such as downstream in the hydroponic cultivation tank 1. It is necessary to transfer the nutrient solution 53 to a circulation device (not shown).

  The drain pipe 23 can be provided separately from the hydroponics water tank 1, but the connection method is complicated, and therefore it is desirable to connect the joint 211 and integrally form the drain pipe 23. More specifically, as shown in FIGS. 6 (a) and (b), a hole penetrating from the bottom surface side of the joint 211 to the first bottom portion 3 is provided, and the end of the drain pipe 23 is connected to this hole, It is desirable that the inside of the drain pipe 23 and the first flow path 13 of the hydroponic water tank 1 are connected to each other.

  By connecting the drainage pipe 23 to the position, the drainage pipe 23 can be disposed at the end in the longitudinal direction Y without interfering with the connection of the hydroponic water tank 1 using the joint 211. Therefore, for example, the nutrient solution 53 that has flowed downstream can be effectively transferred to another.

  The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to these embodiments, and other embodiments may be used without departing from the spirit and teaching of the claims. There are improvements and modifications. Those skilled in the art will readily understand that all such improvements and modifications are included in the technical scope of the present invention.

  The water culture tank in this embodiment prevents water stoppage of the flow path inside the tank due to the spread of the roots accompanying the growth of the plant, maintains the flow of the nutrient solution, and increases the overall rigidity, It can be easily connected using a joint.
