Abstract

PURPOSE:To provide a water tank for fish culture, suitable for culturing and protecting fishes and convenient to handle. CONSTITUTION:The objective water tank 1 monolithically produced by FRP is composed of a box-shaped body having a rectangular inner space 10 and a leg part 8 extending in the longitudinal direction and attached to the bottom wall 2 so that the leg part may be protruded downward. In the leg part 8, a conduit 9 extending in the longitudinal direction is formed and plural water- injection holes 91 opened to the inside of the water tank are arranged on the upper part of the conduit 9 leaving a prescribed space in the longitudinal direction. A water-supplying part 50 is formed at one longitudinal end part of the water tank 1 and a water-discharge part 54 is formed at the other end part.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an FRP water tank used for hatching fish and raising fry.

[0002]

2. Description of the Related Art Conventionally, as a fish tank for raising fish, a fixedly installed concrete tank is generally used, and various water supply methods are adopted in this tank to suit fish breeding. ..

[0003]

The above concrete water tank has the following drawbacks. That is, (a) Since the water is released during the manufacturing of the water tank, the work of pulling out the water is required at the time of use, which requires a long period of time.

(B) Cracks are likely to occur in cold weather,
Inferior in durability.

(C) Since the inner surface of the aquarium is rough, the fish body is likely to be damaged by contact with the fish being raised,
In addition, algae easily adheres to the wall surface, and cleaning it takes time. (D) It is difficult to carry because the water tank itself is heavy.

[0006] The present invention has been made in order to eliminate such conventional drawbacks, and an object of the present invention is to provide a fish breeding aquarium suitable for growing and protecting fish and convenient for handling the aquarium. It is a thing.

[0007]

SUMMARY OF THE INVENTION The present invention is a water tank made of an integrally molded product made of FRP, which is formed in a box shape in which a rectangular parallelepiped internal space is formed, and extends in a length direction on a bottom wall. The legs are formed so as to project downward, and a water conduit extending in the lengthwise direction is formed in the legs, and a plurality of water injection ports that open inside the water tank are formed in the lengthwise direction above the water conduit. The water supply section is formed at one end in the lengthwise direction of the water tank, and the water discharge section is formed at the other end, which are arranged at predetermined intervals.

Guide rails extending in the lengthwise direction are provided on the inner surfaces of both side walls of the upper part of the water tank so as to face each other, and a plurality of lids are detachably engaged with the guide rails in the lengthwise direction. It is preferable to adopt a configuration.

[0009]

In the above structure, since it is an integrally molded product made of FRP, it is lightweight and easy to carry, and since the inner surface is a smooth surface, there is no risk of scratching the fish and algae hardly adheres,
Furthermore, the process of providing a water supply means is also easy.

[0010]

1 and 2, a water tank 1 is formed of an integrally molded product made of FRP, and a rectangular parallelepiped internal space (a breeding tank 10) is formed from a bottom wall 2, both side walls 3 and both end walls 31. A flange 4 is formed on the upper ends of both side walls 3 and both end walls 31. On the lower side of the bottom wall 2, a pair of parallel leg portions 8 extending in the length direction are formed so as to project downward, and a water conduit 9 is formed in the leg portion 8 in the length direction, and one end portion is formed. Is provided with an inlet 90 for the water conduit 9. A water supply unit 50 partitioned by a weir plate 51 is formed at one end in the lengthwise direction of the water tank 1, and a water discharge unit 54 partitioned by a weir plate 52 is formed at the other end.
And a screen 53 is arranged on the center side of the barrier plate 52.

As shown in FIG. 3, a pair of recesses 21 extending in the longitudinal direction are formed in a part of the bottom wall 2 in parallel with each other.
The protrusion 81 that holds the recess 21 and protrudes downward is
It is formed of RP, and the core material 80 is filled inside the protrusion 81, and the extension portions 82 at both upper ends of the protrusion 81 are attached so as to cover the lower surface of the bottom wall 2. Further, the lid 99 is attached to the upper portion of the water conduit 9 to form the water conduit 9 in the recess 21. Then, water injection ports 91 are formed in the lid 99 in the longitudinal direction at predetermined intervals.

As shown in FIGS. 1, 2 and 4, U-shaped guide rails 6 extending in the lengthwise direction are provided on the inner surfaces of both side walls 3 at the top of the water tank 1 so as to face each other. A plurality of lids 7 are detachably engaged with both ends of the lid 6 in the length direction. Rollers 70 are attached to both ends of the lid 6 so that the rollers 70 roll in the guide rails 6. Each lid 7 can be fitted into or removed from the end 61 of the guide rail 6.

In the above structure, water is supplied to the water supply section 50 by a water supply means (not shown), the dam plate 51 is caused to overflow, and water is supplied to the breeding tank 10, and the water conduit 9 is provided.
Water is jetted from the bottom of the breeding tank 10 through the water jet port 91, overflows from the dam plate 52 at the other end, and is drained into the water discharge part 54. At this time, the fish in the breeding tank 10 are stopped by the screen 53 in front of the dam plate 52 so as not to be washed away by the water overflowing the dam plate 52. Small holes may be formed in the dam plate 51 and the dam plate 52, and water may pass through the small holes. The water in the discharge part 54 may be discharged by an appropriate means (not shown). Further, small holes may be formed in the dam plates 51 and 52 so that water can also pass through the small holes.

In this way, water is supplied from the water supply section at one end and discharged from the other end, and water is supplied throughout the breeding tank 10 from the water injection ports 91 formed in large numbers at the bottom. If this is done, a flow of water will occur throughout the breeding tank 10, and an optimal state for breeding fish will arise. Further, when it is necessary to block direct sunlight, the required number of lids 7 may be attached, and they can be attached and detached one by one from the end portion 61 of the rail 6 and moved along the rail 6. Because it is good, the work can be easily done.

Further, since this aquarium is made of FRP, the inner surface is smooth and does not damage the fish body, and the water conduit 9 is formed on the inner surface of the breeding tank 10 without forming protrusions. Can be easily processed, and since the water tank 1 is light in weight, it is convenient to carry, and since the water tank 1 is equipped with the legs 8, it can be installed at any place.
