DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention can show and transport live fish having a skin respiratory property such as flatfish in a high humidity atmosphere for a long time (about 2 to 3 days). This is a showcase of live fish dripping in live water.

[0002]

2. Description of the Related Art Conventionally, when live fish such as flatfish are allowed to survive for a long time (about two to three days) in an urban area, or when the live fish are transported by truck in a live state for a long time,
It adopts a method of storing live fish in the seawater in the aquarium.

[0003]

In the case of the conventional live fish survival method, when live fish are to be shown or stored in a live state for a long time in an urban area, a large amount of seawater must be transported to the urban area and stored in an aquarium. When transporting live fish for a long time in a truck in a live state, it is necessary to mount a heavy tank with a large amount of seawater on the truck and run it, which makes the truck run poorly. There's a problem.

[0004]

SUMMARY OF THE INVENTION In order to advantageously solve the above-mentioned problem, in the showcase for live fish dripping of live fish according to the present invention, a transparent box 2 for storing live fish is placed inside a transparent cool tank 1. The transparent box 2 accommodated therein is covered with a transparent lid / seawater receiving tray 4 having a seawater dropping hole 3 on the upper part of the transparent box 2 at the uppermost stage.
The inside of each transparent box 2 is connected to an oxygen supply source 7, and a seawater container 8 for dropping seawater is provided above the transparent lid and seawater tray 4 in the upper part of the transparent tank 1. Circulation line 1 that circulates seawater 9 in the lower part of the building
The seawater transfer pipe 13 of the seawater transfer pump 12 for transferring the seawater 9 below the transparent tank 1 is connected to the seawater container 8 for dropping seawater with the seawater cooler 11 interposed therebetween.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of the present invention, in which a sealed synthetic resin made of a transparent synthetic resin such as an acrylic resin is placed on the upper part of a tank body 14 of a sealed double structure made of a transparent synthetic resin such as an acrylic resin. The tank lid 15 having a double structure is detachably attached to form the cold-insulating transparent tank 1, and a refrigerant supply port 17 and a refrigerant discharge port 18 are provided in the closed space 16 of the tank body 14 and the tank lid 15. A refrigerant such as cold water or cold air is circulated in the closed space 16.

[0006] A plurality of transparent boxes 2 for storing live fish made of a transparent synthetic resin such as an acrylic resin are provided in a transparent cold storage tank 1.
A transparent lid / seawater tray 4 made of a transparent synthetic resin such as an acrylic resin is removably fitted on the top of the uppermost transparent box 2, and seawater is dropped on the transparent lid / seawater tray 4. A hole 3 is provided, a bottom plate 5 of each transparent box 2 is provided with a through hole 6 for dropping seawater, and a live fish 19 such as a flat fish is placed on the bottom plate 5 of each transparent box 2. The seawater dropping through hole 6 of the bottom plate 5 and the seawater dropping hole 3 of the transparent lid / seawater receiving tray 4 are disposed near the gills of the live fish 19. Further, gas flow holes 20 are provided in the bottom wall 5 of the transparent box 2 other than the lowermost row and the partition wall in each transparent box 2.

A seawater container 8 for dropping seawater is attached to a lower portion of the tank lid 15, a drop water amount control valve 21 is connected to a drain port at the bottom of the seawater container 8, and the transparent tank 1 is provided.
A support plate 22 having a large number of water holes 30 is erected on the lower side of the inside, and seawater 9 is accommodated below the support plate 22 and a seawater transfer pump 12 is fixed below the support plate 22 in the transparent tank 1. One end of a seawater transfer pipe 13 having a hose is connected to the discharge port of the pump 12, the other end of the seawater transfer pipe 13 is connected to a seawater container 8, and the upper end of the overflow pipe 23 is While being connected to the upper part of the seawater container 8, the lower end of the overflow pipe 23 is disposed near a water inlet provided on the support plate 22,
A float switch 24 is mounted in the seawater container 8, and the pump 12 is operated and stopped by turning on and off the float switch 24. A bearing frame member 26 having a peripheral ridge 25 for preventing slippage is fixed on the upper portion of the bearing plate 22, and the lowermost transparent box 2 is placed on the bearing frame member 26.

A pump 27 for circulating seawater disposed in the lower part of the seawater in the transparent tank 1 is fixed to a bottom plate of the transparent tank 1, and one end of the circulation line 10 is connected to a discharge port of the pump 27. The other end of the circulation line 10 is open at the lower part in the transparent tank 1, a seawater cooler 11 is interposed in an intermediate portion of the circulation line 10, and an oxygen tank formed of an oxygen cylinder is provided outside the transparent tank 1. A supply source 7 is installed, and the oxygen supply source 7 and the uppermost transparent box 2 are
4 is connected via an air supply pipe 28 and a joint 29 penetrating the wall portion.

[0009] The seawater cooled in the cool-keeping transparent tank 1 is supplied to the seawater container 8 by a seawater transfer pump 12.
And the seawater dropped from the seawater container 8 onto the transparent lid / seawater receiving pan 4 is supplied from the seawater drip hole 3 of the transparent lid / seawater receiving pan 4 to the vicinity of the gill of the live fish 19 in the uppermost transparent box 2. Then, the water is dropped from the seawater dropping through hole 6 of the bottom plate 5 in the uppermost transparent box 2 to the vicinity of the gill of the live fish 19 in the second transparent box 2, and then in the vicinity of the gill of the lower live fish 19 in order. Seawater is dropped into the transparent box 2 and oxygen is supplied from the oxygen supply source 7 into the transparent box 2, so that the live fish 19 in the transparent box 2 can survive for a long time.

[0010]

According to the present invention, a transparent box 2 for storing live fish is accommodated in a cold-storage transparent tank 1 in a stacked manner, and a transparent lid 2 having a seawater drip hole 3 above the uppermost transparent box 2. Put the seawater tray 4 on the bottom plate 5 of each transparent box 2
The transparent box 2 is connected to an oxygen supply source 7 and the inside of each transparent box 2 is connected to an oxygen supply source 7. And a seawater cooler 11 interposed in a circulation line 10 for circulating the lower seawater 9 in the transparent tank 1, and a seawater transfer pipe of a seawater transfer pump 12 for transferring the lower seawater 9 in the transparent tank 1. Since 13 is connected to the seawater container 8 for dripping seawater, low-temperature seawater can be dropped on the live fish 19, and the live fish 19 can survive for a long time, and the live fish 19 can survive for a long time with a small amount of seawater used. It can be shown and transported in a state of being closed.
