[Prior Art and Problems to be Solved by the Invention]

 When fishing with a fishing boat, etc., the fish caught is temporarily stored in a tank provided at the bottom of the ship and transported to a destination such as a landing site, but in order to maintain the freshness of the fish. Needs to cool the temperature of the seawater in the aquarium to a temperature equivalent to the temperature of the seawater in which the fish lived. For this reason, fishing boats or large vehicles that carry live fish over long distances and for long periods are equipped with a seawater cooling device as shown in Japanese Patent Application No. 3-7622. As a seawater cooling device, a circulation type cooling device is widely used in which seawater in a water tank is sucked and circulated while being cooled by an evaporator that constitutes a refrigeration cycle.

This type of seawater cooling device is used for transporting caught fish over a long period of time, but when there is a space limitation or cost problem, such as in a small automobile, Considering especially short-distance transportation, as shown in FIG. 4, ice i was directly put into the water tank 10 instead of providing the seawater cooling device.

Therefore, there is a problem that the concentration of seawater is lowered due to melting of the ice i put into the aquarium 10, which adversely affects live fish.

The present invention has been made in view of the above problems of the prior art, and is suitable for a short-distance transport vehicle or the like, and can control the liquid temperature in a water tank with a simple configuration. It is an object of the present invention to provide an aquarium device for transporting live fish.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example in which the aquarium device for transporting live fish of the present invention is mounted on a small automobile, FIG. 2 is a perspective view showing a partial cross section of the structure of the heat insulating case shown in FIG. 1, and FIG. It is an apparatus block diagram which shows the fish tank apparatus for live fish transportation which concerns on the Example.

As shown in FIG. 1, the aquarium device for transporting live fish according to this embodiment has one or a plurality of aquariums 20 (three in this embodiment). Fish can be stored according to temperature. As shown in FIG. 3, drain pipes 21 are attached to the bottoms of these water tanks 20, and the liquid (seawater in the case of saltwater fish) from the drain pipes 21 causes the heat exchange described later. It is led to the pipe 22.

On the other hand, a heat insulating case 23 is provided near these water tanks 20, and the heat insulating case 23 is, for example, as shown in FIG. 2, a box body 24 made of fiber reinforced plastic and a heat insulating material. 25, and an opening 26 is formed in the upper surface so that a cooling source i such as ice can be directly put therein. Further, a drain pipe (not shown) is provided on the bottom surface. The shape and structure of the heat insulating case 23 are not particularly limited, and can be appropriately modified according to the type of the cooling source i to be charged and the like. A lid may be provided to cover the opening 26.

At the bottom of the heat insulating case 23, a heat exchange pipe 22 made of titanium is arranged in a meandering manner, and one end thereof is connected to the supply pipe 27 communicating with the drain pipe 21 of the water tank 20 described above. The other end is connected to a return pipe 28 that returns to the water tank 20. The circulation system that returns from the drain pipe 21 to the water tank 20 through the heat exchange pipe 22 constitutes the liquid circulation system 30 of the present invention.

The meandering position of the heat exchange tube 22 may be set at a position where it comes into contact with a cooling source i such as ice, not at the bottom of the heat insulating case 23. Further, the heat exchange tube 22 does not have to be provided in a meandering shape as long as the liquid circulation time in the heat insulating case 23 can be made as long as possible.

The circulation of the liquid in the water tank 20 by the liquid circulation system 30 described above is performed by the water pump 31 provided in the liquid circulation system 30. The operation / stop of the water pump 31 is performed by the controller ( It is controlled by the control means) 32. The information about the liquid temperature of each water tank 20 detected by the temperature sensor 33 provided for each water tank 20 is input to the controller 32, and the water pump 31 is activated when the temperature exceeds a predetermined set temperature. To output a control signal. When the liquid temperature of the water tank 20 is suitable for live fish, the water pump 31 corresponding to the water tank 20 is stopped.

Next, the operation of this embodiment will be described. Ice or the like serving as the cooling source i is put into the heat insulating case 23 to store live fish in each water tank 20. The temperature of the liquid in the water tank 20 is detected by the temperature sensor 33, and the information is taken into the controller 32.

In this controller 32, when the liquid temperature detected by the temperature sensor 33 rises to a predetermined value or more, the water pump 31 is operated to move the liquid in the water tank 20 to the titanium heat exchange provided in the heat insulating case 23. After guiding to the pipe 22, it is returned to the water tank 20 again.

At this time, in the titanium heat exchange pipe 22, heat is exchanged between the cooling source i such as ice and the liquid to cool the liquid, and the cooled liquid is returned to the water tank 20. It On the other hand, when the liquid temperature in the water tank 20 drops below a predetermined value, the controller 32 stops the water pump 31.

The titanium heat exchange tube 22 has an excellent heat transfer property, and in the live fish transport water tank apparatus of the present embodiment, the liquid in each water tank 20 is controlled with a simple configuration according to each set temperature. Therefore, it becomes possible to transport live fish of various species with different habitat conditions all at once.

Further, since the ice i is not put into the water tank 20 as in the conventional case, the concentration of seawater does not decrease and the live fish is not adversely affected. Further, since the cooling source i such as ice may be put only in the heat insulating case 23, the work of putting the ice i is extremely simple.

Further, the device itself has a simple structure, and if the drain pipe 21 of the water tank 20 which has been used conventionally is used, retrofitting can be easily performed, so that the device can be manufactured at low cost.

Moreover, the heat insulating case 23 can store not only the cooling source i such as ice, but also the fish that have died during transportation and the like. By doing so, the heat insulating case 23 functions as a fresh fish tank, it is possible to transport fresh fish while maintaining freshness, and it is possible to prevent contamination in the aquarium 20 for storing live fish.

[0021]

[Effect of device]

 As described above, according to the present invention, while controlling the liquid temperature in the aquarium to a temperature suitable for live fish without changing the conditions such as liquid concentration, various live fish with different habitation conditions can be collectively alive. It becomes possible to carry it.

Further, the device itself has a simple structure, and if the drain pipe of the water tank which has been used conventionally is utilized, the device can be easily remodeled, so that the device can be manufactured at low cost.

Moreover, since a cooling source such as ice may be put only in the heat insulating case, the work is extremely easy.

[0024] In addition, if the heat insulating case not only stores a cooling source such as ice, but also stores fish that have died during transportation, fresh fish can be transported while maintaining freshness. In addition, it is possible to prevent contamination in the aquarium containing live fish.
