[0008]

In the water tank for transporting live fish of the present invention, the wall material forming the water tank body has a three-layer structure in which the inner and outer layers are FRP materials and the lightweight heat insulating material is sandwiched as an intermediate layer. Therefore, it is light in weight as a whole, yet has sufficient strength, and has an excellent heat retaining ability that almost prevents the transfer of heat from the outside air to the water in the water tank by disposing the heat insulating material as the intermediate layer. become. This allows live fish to be transported while maintaining a water temperature that is lower than the optimal temperature for live fish, which can inhibit fish metabolism and at the same time increase the amount of dissolved oxygen in water, allowing live fish to be transported without weakening it. .

Further, in the present invention, the water intake is provided in the aquarium body,
The water taken from there is discharged from the outlet to generate a circulation in the aquarium. This prevents weakening of live fish and enhances the filtration efficiency of fish dung, dust and the like in water. Furthermore, the amount of dissolved oxygen in water can be increased by adopting a bubble pump as a water supply means from the water intake port to the water discharge port.

Further, the water tank from the intake port to the water discharge port is arranged in the wall surface of the water tank body by partially removing the heat insulating material which is the intermediate layer, whereby the water tank can be compactly assembled and at the same time the heat insulation in the water channel can be achieved. It is also possible to secure the sex.

According to the present invention, the water temperature can be maintained more easily by providing the water temperature adjusting means. In that case, the water temperature can be effectively maintained by arranging the heat exchanger of the water temperature control means on the water channel that feeds water from the water outlet to the water outlet, which is effective when the fishermen and producers are on remote islands. Is. Moreover, since the water tank body is excellent in heat retention, the output of the water temperature adjusting means may be small.

In addition, heat exchange with the bubble pump in the water channel in the water tank wall
Since the vessels are arranged, there is no direct contact between the fish and
Not only to damage but also to reduce the effective volume in the aquarium
Nor. In addition, a heat exchanger is placed in the water flow of the bubble pump.
Therefore, the heat exchange efficiency is improved.

In some embodiments of the present invention, the blower of the bubble pump is provided with a check means so that the water in the water tank does not flow backward, so that safety measures against accidents such as blower stop during transportation are taken.

Further, by forming a fork insertion groove of a forklift on the outer bottom surface of the water tank body, it is possible to improve convenience when entrusting transportation to a shipping company such as a ship or vehicle.

Reference numeral 10 is a filter, 11 is a water intake port, 12 is a water discharge port, and 13 is a bubble jetting part in the lower part of the water channel 9, which causes a bubble pump action. The water in the water tank body 2 is filtered by the filter 10 and sent from the water intake 10 to the water outlet 12, and the circulation efficiency improves the filtration efficiency.

A heat exchanger 14 is arranged inside the water channel 9, and heat exchange efficiency is enhanced by arranging the heat exchanger 14 in a portion where a high flow velocity is generated.

A bubble generator 15 made of porous stone is arranged inside the water tank body 2. The blower 16 blows air to the bubble blower 13 of the bubble pump.
Since the air is sent by branching the air passage from the water tank 1, the water tank 1 can be made compact. Further, 17 is a check valve, and 18 is a drain trap. As a result, water does not flow backward even in the event of an accident such as the blower 16 stopping. Reference numeral 19 is a restriction orifice for adjusting the air distribution between the bubble generating part 15 and the bubble ejecting part 13.

The present invention is not limited to the above embodiment. For example, the heat insulating material inside the water tank body does not have to be a urethane foam material, and the position of the water intake can be a side surface near the bottom. The filter can also be placed near the water outlet.
