Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a water tank made of a transparent material installed in an aquarium or the like for appreciating seafood and aquatic animals.
[0002]
[Prior art]
In an aquarium or the like, generally, fish and the like are kept in a large aquarium, and the viewer and the fish are completely separated by the side wall of the aquarium. Therefore, the viewer cannot feed the fish or touch it directly by hand. If this is possible, the fun in the aquarium is expected to increase.
[0003]
[Problems to be solved by the invention]
The present invention has been made in response to the above-mentioned demands, and has a novel structure that can feed a fish directly or touch it by hand through the side wall of the tank. The purpose is to provide.
[0004]
[Means for Solving the Problems]
The water tank according to the present invention has an opening (5) formed in the lower part of the side wall (2) of the water tank main body (1) made of an airtight container, and the communication path that connects the inside of the tank and the opening (5) inside the opening (5). (6) is provided downward, the lower end of the communication path (6) extends below the lower end of the opening (5), the water tank body (1) is provided with a suction device (4) for depressurizing the upper space , and the water tank it is characterized in that the circulation pipe for returning to the upper portion of the body water tank body of water in (1) from the communication passage (6) after extraction filtration as an overflow water (1) (8) is provided.
[0005]
Preferably, reservoir for recycling pipe (8) (9), circulation pump (10), the physical filtration tank (11), biological filtration tank (12), pre-water tank (13), sterilizers (14), the temperature A regulator (15) and a foam separator (16) are provided in this order.
[0006]
[Action]
While decompressing the upper space of the water tank main body (1) by the suction device (4), water is supplied into the water tank main body (1) to raise the water level in the water tank to a predetermined position. By adjusting the degree of vacuum, water is allowed to enter the lower end of the communication path (6). Since the lower end of the communication path (6) extends below the lower end of the opening (5), water does not overflow from the opening (5).
[0007]
In this state, it is possible to directly touch the fish swimming by putting the hand into the tank from the opening (5), and it is also possible to feed the fish in the tank from the opening (5).
[0008]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be specifically described with reference to the drawings.
[0009]
1-3, the large-sized water tank main body (1) installed in an aquarium etc. consists of an airtight container. The side wall (2) is formed of a transparent material such as glass or acrylic resin. Openings (5) are formed in the lower portions of the left and right side walls (2) of the water tank body (1). A plurality of openings (5) having a size of about 20 cm × 20 cm are usually provided at regular intervals in the horizontal direction. The opening (5) may also be long in the horizontal direction. Inside the opening (5), a communication path (6) that communicates the opening (5) and the lower part in the tank is provided downward. The lower end of the communication path (6) extends below the lower end of the opening (5). The communication path (6) is formed by installing a drooping member (7) having a reverse "S" shape in the longitudinal section on the inner surface of the opening (5) and arranging vertical end plates at both ends thereof.
[0010]
A circulation pipe (8) for circulating water from the right communication path (6) to the upper part of the water tank body (1) is provided. In the communication path (6), the level of the upper end of the circulation pipe (8) is lower than the lower end of the opening (5) and higher than the lower end of the communication path (6). The circulation pipe (8) includes a water storage tank (9), a circulation pump (10), a physical filtration tank (11), a biological filtration tank (12), a reserve water tank (13), a sterilizer (14), and a temperature controller (15 ) And a foam separator (16) are provided in this order.
[0011]
4 and 5 show a modification of the communication path. In FIG. 4, the communication path (6) is provided with a drooping member (17) having an inverted “L” -shaped vertical section consisting of a horizontal plate (17a) and a vertical plate (17b) on the inner surface of the opening (5). It is formed by arranging vertical end plates at both ends. In FIG. 5, the opening (5) is long in the horizontal direction, and its lower edge is slightly inclined outward. Further, the communication path (6) includes a drooping member (18) having a substantially cross-sectional shape with a vertical cross section comprising an inclined plate (18a) having an inwardly descending slope and a vertical plate (18b) provided at the inner end thereof. It is formed by installing on the inner surface of the opening (5) and arranging vertical end plates at both ends thereof.
[0012]
In the water tank configured as described above, water is supplied into the water tank body (1) while reducing the upper space of the water tank body (1) by the suction device (4), and the water level in the tank is raised to a predetermined position. . By adjusting the degree of vacuum, water is allowed to enter the lower end of the communication path (6). Since the lower end of the communication path (6) extends below the lower end of the opening (5), water does not overflow from the opening (5). The pressure reduction value in the water tank body (1) is determined by the interval between the water level in the water tank body (1) and the water level in the opening (5). In the communication passage (6), the water overflowing inside the upper end of the circulation pipe (8) is once stored in the water storage tank (9), and then the physical filtration tank (11), biological filtration tank by the circulation pump (10). (12), the preliminary water tank (13), the sterilizer (14), the temperature controller (15), and the foam separator (16) to be purified and circulated to the upper part of the water tank body (1) .
[0013]
In this state, it is possible to put a hand into the tank from the opening (5) and directly touch the fish swimming, etc., or to feed the fish in the tank from the opening (5).
[0014]
【The invention's effect】
According to the present invention, not only can the fish in the aquarium be appreciated, but also the fish swimming in the tank can be directly touched through the opening (5) and the fish in the tank can be touched. Can also be fed.
[0015]
In addition, the configuration is simple and management and maintenance is easy, and the communication path (6) is provided inside the opening (5), so it is compared to the one provided outside the opening (5). The water tank installation space is small, and there is no risk of damage due to contact with the communication passage (6), so safety is high.
