Description

[Detailed description of the invention] [Objective of the invention] Industrial field of application The present invention provides a truck for live fish that eliminates damage caused by failure and enables efficient and efficient high-density transportation when transporting live fish. This relates to storage cases and storage tanks during transportation.

Conventional technology Live fish transportation not only contributes to the development of the fisheries industry through aquaculture operations such as seed production, stocking, and farming, but also allows live fish restaurants and ordinary households to enjoy live seafood. In the future, social demands for rapid and mass transportation will continue to increase.

Although live fish are mainly transported by truck, the live fish are generally transported by swimming in the environmental water in the aquarium. Due to the agitation of the environmental water, the live fish have the drawback of colliding with each other or with the inner wall of the aquarium, damaging the live fish and reducing their commercial value.

In addition, since the environmental water contained in the aquarium is allowed to swim freely, in order to minimize the above drawbacks, live fish can only be accommodated at a weight ratio of approximately 10% to the environmental water. However, it had the disadvantage of being economically inefficient.

Problems to be Solved by the Invention The present invention solves the following problems when transporting live fish by truck:
Storage case and housing for live fish truck transportation that enables efficient and efficient high-density transportation by eliminating damage or death to live fish caused by agitation of environmental water in an aquarium during rolling, starting, and stopping. The purpose is to provide a tank.

[Structure of the invention]

Means for Solving the Problems In view of the above, the present invention forms inner and outer walls with a substantially U-shaped cross section so as to wrap outward from the opening edge of a container body to define a space and an inner wall of the container body. A storage case has numerous communication holes drilled in the inner wall of the outer wall, and a partition wall installed inside the aquarium forms a live fish storage section and an overflow drainage channel, and the live fish storage section has a water tank with a large number of holes extending outward from the opening edge of the container body. The housing cases are stacked in multi-tiered form, with the inner and outer walls being rolled in toward each other to form a substantially U-shaped cross section to define a space, and the inner and outer walls having numerous communication holes. An attempt has been made to solve the above-mentioned drawbacks by providing a storage tank in which an air bag is attached to the lower surface of a lid that covers the top of the tank.

Effects Regarding the storage case of the present invention, the storage case is first fitted into the live fish storage part of an aquarium filled with environmental water and allowed to fall downward, and then live fish are introduced, Then, by fitting the next storage case into the aquarium and letting it fall downward, live fish can be stored in the storage case, and by repeating this process, the storage cases can be stored in the aquarium in multiple stages. Moreover, even when stacked in multiple stages, environmental water flowing from below can be maintained flowing through the communication holes through the space.

Next, regarding the storage tank, it has the same effect as above, and by pressing the surface of the environmental water with an air bag filled with compressed air, it can be used to prevent rolling, starting, and stopping during truck transportation. It is possible to absorb the disturbance of the generated environmental water, and it is also possible to overflow and discharge the environmental water containing old waste flowing from below.
