Description

The present invention relates to a biotope suitable for forming a habitat for organisms close to natural forms, and particularly to a biotope that is installed in a schoolyard or a park of a school and is easy to use for education.

In recent years, there are fewer forests and rivers around us, and the need for environmental education for children and students is increasing.
Biotope is an effective way for children and students to learn together with teachers about aquatic plants, aquatic plants, plankton, small fish, insects, plants and other ecosystems such as rivers, ponds and swamps.
However, in the past, installation of a biotope has been difficult to disseminate due to the need for extensive construction.
For example, Patent Document 1 discloses a water-circulating biotope provided with a water storage unit such as an artificial pond or river and a water purification means in which a hydroponic plant is grown.
However, the biotope disclosed in the publication requires a large-scale creation, and there is a problem that it takes a long time to form an ecosystem.

  An object of the present invention is to provide a biotope that is lightweight, easy to install, stable for a long period of time, and capable of observing a comprehensive ecosystem.

  The biotope according to the present invention is a biotope that forms a living habitat for a living organism based on a tank and a foamed resin body installed inside the tank, and is provided with a soil portion and a river on the top surface of the foamed resin body. For forming a water system combined with the river by providing a pond and a swamp between the tank wall and partially cutting the foamed resin body. It is characterized by having a pump driven by photovoltaic power generation using a solar panel.

Here, the foamed resin body refers to a foamed body such as foamed polystyrene or foamed urethane, and has a merit that it is lightweight and can be easily processed.
In addition, the use of a solar panel as the drive power source is useful for solar power system education.

Here, in order to stabilize the water quality of the aqueous system over a long period of time, it is preferable to dispose a purification material that combines bark, charcoal and shells in the middle of the aqueous system.
In this case, bark, charcoal and shells were used as purification materials because they are effective in maintaining water quality without destroying the growth environment of aquatic organisms such as plankton. Cedar bark is used as the bark. The oyster shell is preferred as the shell.
For example, it is good to mix and mix in the range of 20-40% oyster shell, 40-60% charcoal, and 20-40% cedar skin by mass.

  The foamed resin body is lightweight and can be easily processed into a free shape. However, since a large buoyancy is generated with respect to water, this foamed resin body will float if cracks or gaps occur in the fixed part of the foamed resin body. However, in the present invention, the foamed resin body is fixed to the bottom surface of the tank and a drainage groove is formed on the back surface of the foamed resin body, and the drainage groove is connected to the outside provided on the bottom surface of the tank. The drainage groove does not communicate with the water system in a normal state, but when water enters the back surface of the foamed resin body, the intruded water is drained from the drainage hole. As a result, the troubles as described above do not occur.

In the biotope according to the present invention, since the base portion is formed of a foamed resin body, a soil layer can be formed on the base to plant vegetation and small trees or to create a river. Because it was placed in, you can easily build a pond or swamp by cutting out a part.
In addition, combining solar power generation systems with solar panels can contribute not only to energy saving but also to comprehensive education combined with the natural environment.

The external view of the biotope based on this invention is shown. The layout of the biotope is shown. The structural example of a tank and a foamed resin body is shown. The back surface perspective view of a foamed resin body is shown. A cross-sectional view of the biotope is shown. The drainage explanatory drawing in case water infiltrates into the back surface side of a foamed resin body is shown.

A biotope 100 according to the present invention will be described below with reference to the drawings.
FIG. 1A shows a state in which water flows along a river 4 from a pond 3 in the front to a swamp 5 provided on the back side, and FIG. 1B shows a state in which the water is seen from the side.
The tank 10 is an example in which a side plate 12 made of resin is erected from the periphery of a PVC bottom plate 11 and the upper end is reinforced by a metal upper frame 13.
Among the surrounding side plates 12, at least a portion provided with the pond 3 can be observed inside the pond using a transparent plate.
A foamed resin body 20 is disposed inside the tank 10 as a base body. By processing this foamed resin body, the pond 3, the swamp 5 and the like are provided between the side plate 12 and a part of the bottom surface 11 of the tank 10. In this example, a river 4 is formed on the upper surface, a soil layer is formed around the river 4, and a vegetated grassland 1 and a rocky mountain 2 are formed.
The habitat of such an organism is not limited to this, and can be freely designed.

FIG. 2 shows a configuration example of the biotope and peripheral devices.
The inside of the tank 10 is partitioned by partition plates 17, 17a and 17b as shown in FIG.
The water that flows from the pond 3 to the swamp 5 along the river 4 as indicated by reference numeral 7 flows to the purification section 14 divided by the partition plate 17.
As shown in the cross-sectional view along the line A-A in FIG.
The water that has passed through the purification unit 14 exceeds the upper end of the partition plate 17a, and the supernatant liquid of the first water storage unit 14a accumulates in the second water storage unit 15 when it exceeds the upper end of the partition plate 17b. Pump up 41 to form an aqueous system.
The pump 40 is operated by a drive power source in which the current generated by the solar panel 60 is converted and controlled by the control unit 50.
The display unit 51 displays the power generation output.

The foamed resin body 20 crosses the vertical and horizontal groove portions 21 and 22 as shown in the rear perspective view of FIG. 4, and the groove portion shows the bottom surface 11 of the tank 10 as shown in FIG. It communicates with a drainage hole 11a provided through.
5C, a plate 24 is bonded to the bottom surface 11 as shown in a cross-sectional view taken along the line CC, a stud bolt 25 is inserted into the upper portion of the foamed resin body 20, and a nut 27 is inserted through a fixing plate 26. Fastened and fixed.
The plate 24 is located in the back surface recess 23 of the foamed resin body 20 shown in FIG.
Normally, there is no problem because the foamed resin body 20 is fixed to the bottom surface 11 with a stud bolt. However, as shown in FIG. 6, a gap d is formed on the back surface side of the foamed resin body 20, and the pond 3, the swamp 5 and the like. Even if the water W enters from the inside, the infiltrated water is discharged from the drain hole 11a on the bottom surface through the grooves 21 and 22, so that the foamed resin body 20 does not float by buoyancy.
Moreover, when it rains and a water level becomes high, it will flow outside from the water flow hole 16 provided in the side plate 12. FIG.
