This invention relates to a fish tank/water tank/cultivation device that can also be used to raise freshwater fish using bacteria contained in an active water purifier.

[Prior Art] Many tools for cultivating plants have been proposed, ranging from large-scale tools for commercial use to small-scale tools that can be used in general households. The common structure of the latter is a tank that stores a certain amount of water, a pump that sucks water into the tank, and a cylindrical body installed above the tank that returns the sucked water back into the tank. The cylindrical body is three-dimensionally formed with a plant holding unit, etc., which is inserted into a receiving hole formed in the side wall of the cylindrical body to receive water falling inside the cylindrical body and to plant plants therein.

[Problem to be solved by the invention] What is wrong with such conventional plant hydroponic cultivation equipment? In this case, the growth of capillary roots is poor due to water flow inside the plant holding unit.
Furthermore, since a pump with a valve is used, it is easy for the pump to malfunction due to foreign objects, and there is a drawback in that the water cannot be used effectively.

This invention eliminates the above-mentioned conventional drawbacks, minimizes the water flow in the plant hydroponic shelf, improves the growth of capillary roots of plants,
By increasing the absolute value of water dripping and water surface area, we increase the oxygen content in the water, and use an organic active water purifier that doubles as an activator for circulating water and a fertilizer during plant growth to improve the growth of freshwater fish. The object of the present invention is to provide a hydroponic cultivation device that can also be used as a fish tank for rearing fish.

[Operation of the Invention] The fish tank/hydroponic culture device of the present invention is constructed as described above, and the water M1 cultivation of plants and freshwater fish breeding will be described below.

As shown in Figure 1, a fish tank 1 is filled with a certain amount of water, an air pump 4, a heater 5, and a bag containing fermented and aged organic matter containing bacteria.
The freshwater fish 1 are placed in a container 14, and the supporting cylinder 2 is placed upright in the fish tank 1 through the rectangular opening 16 of the lid.

Next, the hydroponic shelf 3 is attached to a predetermined position η of the support cylinder 2 using attachment means such as gluing or screwing, and the shelf plate 25 inside the hydroponic shelf and above the support cylinder 2 is attached. Foamed water absorbing material 81 is placed on the top from the back opening 23a of the support cylinder, and pumice 8 is placed on the small side.
2 are spread together to form a seedbed 8, and seedlings 9 such as edible plants 91 and ornamental plants 92, which have been grown elsewhere in advance, are stuffed into this seedbed 8. In this case, the seeds may be sown directly. The heater 5 is energized to warm the water temperature in the fish tank 1 depending on the season and the type of freshwater fish.

In this way, once the preliminary preparations are completed, air is supplied from an air generator (not shown) to the pump housing 41 through the air supply hose 43.
17- is supplied into the air reservoir 44 of 1A. When the 1A is smoothly supplied to the 1A reservoir and the pressure inside the 1A1- reservoir increases, a fish tank is inserted into the pumping hose 46 connected to this air reservoir. The water that has reached the water level inside 1 is pushed up to the water reservoir 29 of the support cylinder 2, and water is discharged into this water reservoir. When water discharging is finished, the pressure in the air reservoir and pumping hose 46 rapidly drops to atmospheric pressure, and when water enters the pumping hose 46 up to the fish tank water level, the air in the air reservoir 44 returns to [%L]. From the beginning, the same operation is performed to intermittently pump a fixed amount (ICC) of water from the fish 1i into the water reservoir 29 at fixed time intervals (5 seconds).

When the water level in this water reservoir 29 reaches the upper end of the drain 27, water drips through this train 27 into the plant hydroponic shelf 3 including the lower shelf board 25, and the water level of this hydroponic shelf rises to the upper end of the drain 27. The water drips onto the lower plant hydroponic shelf 3 through the drain 27, and when the water level on the lowest plant hydroponic shelf 3 reaches the upper end of the drain 27, it returns to the fish tank 1 through this drain, and the water is dripped into the fish tank 1 in a very strong manner. While being purified and activated by the active water purifier 6, the water containing fertilizer components dissolved into the water by the organic strong active water purifier 6 is pumped up again by the arbor 4 and can be used for tub cultivation.

The freshwater fish 7 in the fish Iffi pass through the port 24 and swim in the fish tank 1, and the bacteria and capillary root deposits of plants in the organic strong active water purifier 6 contained in the coarsely woven bag are absorbed. are fed and reared.

In this case, when the water drips from the water M1 cultivation shelf 3 and drain 27 with a large surface area in the air pump 4, it takes in a large amount of air and contains salt, so air is supplied to the fish tank 1. And even if feeding is not required for a long period of time, the freshwater fish 7 in the fish 1fJ1 are not likely to suffer from oxygen deficiency.

The water in the fish tank 1 decreases due to natural evaporation from the water surface and the veins of the leaves of the plants, but when it decreases, it is replenished so that the water does not rot and water leaks do not easily occur.

In addition, the water 11 cultivation 4113 and the shelf board 25 of the support cylinder 2
Small pumice stones are spread over the top, and between these pumice stones (111
If you make things so that they don't slope, the roots of the plants will become tangled in a light layer (=J), and the roots will become stronger, and the water will be dripped from above. Since the roots are easily damaged, nutrients are easily absorbed, and the plant is easy to grow and grows quickly.

[Effects of the Invention] As described above, the present invention provides a fish tank, a supporting cylinder installed in the fish tank, a plurality of plant hydroponic shelves fitted and fixed to the supporting cylinder, and a fish tank. It has an air pump that intermittently pumps water in the tank into a water reservoir provided at the top of the support cylinder, and the water reservoir and each plant hydroponic shelf hold a certain amount of water and direct water downward. It has a dripping water level maintenance drain, and the fish tank contains fertilizer for hydroponic plants, an organic active water purifier containing bacteria to measure water activity, and a heater to raise the water temperature. Cultivation and () f t! Since we have made it possible to measure the length of time between non-administration of food for freshwater fish, it is easy to cultivate plants and raise freshwater fish, there is no photogenic factor that can cause malfunctions, and a large amount of oxygen can be taken into the water. Water can be used effectively, and ornamental fish and iI2I2 animals and plants can coexist harmoniously.
