JPH057439A - Water tank for flowing water - Google Patents

Abstract

PURPOSE:To enable observation of fishes swimming to the flow of water from the (back) front faces by continuously providing water tanks divided with partition weirs, forming the height of the water tanks so as to be successively lower toward one direction, flowing water from the water tank in the upper part to that in the lower part and installing observation stations enabling visual observation of the water flow. CONSTITUTION:Water tanks (1a), (1b) and (1c), each divided with partition weirs 2 and having the height successively lowering toward one direction are continuously molded from an acrylic resin and water discharge devices 3 for feeding water flowing from the upper water tank (1a) to the downward water tank (1c) are provided on the upper surfaces of the partition weirs 2. Observation stations 4 for observing fishes swimming toward the water flow from the front surface are installed on the under side of the partition weirs 2 to enable observation of the fishes swimming to the water flow from the front or back front faces.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a running water tank capable of visually observing the flow of water from the front.

[0002]

2. Description of the Related Art Usually, most of the aquariums displayed in aquariums have no flow of water, and the fish are merely stored in the aquarium. In addition to such a water tank, recently, there is one in which a fish is put in an annular running water tank and the fish swims along with the flow of the water.

[0003]

However, in the above-mentioned aquarium without water flow, only the side of the fish can be seen in most cases, and the fish swimming toward the water flow is observed from the front or the back front. I couldn't do it. Also, in most cases, the annular running water tank was able to observe only the side surface of the fish swimming along the flow of water as described above, and the fish swimming toward the flow of water could not be observed from the front or the back front. The present invention has been made in view of the above problems, and an object thereof is to provide a running water tank capable of observing a fish swimming toward the flow of water from the front or the rear front.

[0004]

[Means for Solving the Problems] In the running water tank of the present invention for achieving the above object, a water tank partitioned by a partition weir is continuously provided, and the height of the water tank is gradually lowered in one direction. The partition weir is provided with a water discharge device for flowing water from an upper water tank to a lower water tank, and an observation place where the water flow can be visually observed from the cross-sectional direction is provided inside the partition weir. It is to be configured as.

[0005]

According to the above construction, since the water discharged from the water discharge device of each partition weir flows from the upper water tank to the lower water tank, it is close to nature from the upper water tank to the lower water tank. The flow of the river can be revealed, and the fish swimming toward the water flow can be observed from the front or the back front at the observation station inside the partition weir, and the water flow can be observed from the cross-sectional direction. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a sectional view of a running water tank according to the present invention, and FIG.
Is a plan view of the same, and FIG. 3 is a sectional view taken along line XX of FIG.

The running water tank A is partitioned by a partition weir 2, and the heights of the tanks 1a, 1b, 1 are gradually lowered in one direction.
c is continuously formed in three tanks, and the water discharged from the water discharge device 3 on the upper surface of the partition weir 2 flows from the upper water tank 1a to the lower water tank 1c, as if the water flows from upstream to downstream. It simulates a river.

Each of the water tanks 1a, 1b, 1c is made of glass or acrylic resin and mounted on the base 4, and the front and rear surfaces of each water tank 1a, 1b, 1c, that is, the surfaces facing the flow of water, are mounted. The slope 2a of the partition weir 2 is inclined to the outside respectively.
The observation site 5 is formed below the partition weir 2 by forming the. In this observation station 5, both slopes 2a of the partition weir 2, that is, the front and rear surfaces of each water tank 1b are transparent, so that the observer moves toward the flow of water flowing from the upper water tank 1a to the lower water tanks 1a, 1b, 1c. The swimming fish can be observed from the front or the back front. In addition, this water tank 1a, 1b, 1c
Is not limited to three tanks as described above, and any number can be provided as needed.

Each partition weir 2 is provided with a water discharge device 3, and the water discharge device 3 in the partition weir 2 of the uppermost water tank 1a is provided.
Attaches the water discharge pipe 3a connected to the water source 7 along the lateral direction of the partition weir 2, and discharges the water from the water source 7 to the water discharge nozzle 3b.
Constantly supplies water to the uppermost water tank 1a. The water discharge device 3 in the partition weir 2 of the intermediate water tank 1b is composed of a water intake groove 6 for collecting water overflowing from the water tank 1b, and a water discharge pipe 3a connected to the water intake groove 6 via a purifying device 8. The water collected in the water intake groove 6 is purified by the purifying device 8 and is supplied from the water discharge nozzle 3b of the water discharge pipe 3a to the lowermost water tank 1c. Furthermore, the partition weir 2 of the lowermost water tank 1c is provided with a water intake groove 6 for collecting the water overflowing from the water tank 1c in the same manner as described above, and the water recovered in the water intake groove 6 is purified as it is or by the purifying device 8. Water is supplied to the water discharge pipe 3a in the partition weir 2 of the uppermost water tank 1a, and from there, it is supplied to the water tank 1a together with the water from the water source 7 for reuse.

By flowing the water from the upper water tank 1a to the lower water tank 1c in this way, the fish swimming toward this flow can be observed from the front, and the water tanks 1a, 1b, and 1c can be divided from the partition weir 2. You can also observe the river climbing of fish that climbs the water that flows beyond.

[0011]

EFFECTS OF THE INVENTION Water tanks partitioned by partition weirs are continuously provided, and the heights of the water tanks are gradually lowered in one direction, and water is flowed to each of the partition weirs from an upper water tank to a lower water tank. Since a water discharge device is provided and an observation place where the water flow can be viewed from the cross-sectional direction is provided inside the partition weir, a fish swimming toward the water flow can be observed from the front or the rear front. ..

By changing the speed of water flow arbitrarily, it is possible to observe the segregation of fish and other ecology of fish.
