Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, when transporting live fish to a remote location, the fish were transported to the destination while swimming in seawater in a tank.

However, when fish are allowed to swim in a tank, they tend to bite each other and the fish bodies are easily damaged, resulting in poor yields. Therefore, in recent years, it has become common to immerse holding frames in which fish are individually housed in any number of stages in the tank. The seawater in the tank is circulated through a filtration device installed outside the tank to remove waste products while being transported.

However, since the tank equipped with the filtration and circulation system is large, a large truck must be used, and the transportation range is within the range that can be reached in 20 to 30 hours with a large truck, and beyond that, it is necessary to use a large truck. Since the yield of fish decreases, some companies set up farms near the consumption area and transport the fish from the production area to the farm and then ship it later, but this has disadvantages such as higher costs. .

In order to solve the above-mentioned drawbacks, the present invention provides a filtration mechanism in the center of a circular tank and a fan-shaped compartment in the periphery. The fish are loaded and immersed in seawater, and after filtering the seawater in each compartment, the water is sent to the water discharge pipe attached to the inner wall of the tank opposite the lower part of each storage frame, and is delivered to the mouth of the fish in each storage frame. This is a live fish transportation tank that discharges fresh filtered seawater towards the tank.In order for the live fish in the holding frame to always absorb fresh filtered seawater, the volume of the tank has been reduced and the amount of fish relative to the amount of seawater has been reduced. It is characterized by the fact that the yield of fish does not decrease even when the fish are increased in size and transported for a long time, and delicious live fish can be supplied to remote areas at low cost while saving transportation costs.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

A cylindrical filtration chamber 2 is installed in the center of a circular tank 1 with an appropriate diameter and height, and the upper end of the filtration chamber 2 is lower than the upper end of the circular tank 1, and the filtration chamber 2 is placed at an intermediate height position. A receiving plate 3 with many small holes is fitted, a submersible pump 5 is installed in the lower water chamber 4 of the receiving plate 3, a filter material 6 such as activated carbon is filled in the upper chamber of the receiving plate 3, and a wire mesh lid is installed. Attach 7 and remove the center spacer chamber 2.
A radial partition plate 8 is connected to the inner wall surface of the circular tank 1, and an arbitrary number of fan-shaped compartments 9 are provided. Plates 10 of different heights are vertically arranged in a fan shape, and the four corners of each plate 10 are connected with arcuate connecting rods 11, and arcuate frame rods 12 are installed at appropriate intervals on the front and rear arcuate surfaces and the bottom surface. A live fish storage frame 15 is formed by connecting live fish chambers 13 whose front portions are widened and having a frame mold 14 fitted on the upper surface, and an arbitrary number of live fish storage frames 15 are arranged in each compartment 9. A water discharge pipe 16 is provided around the inner surface of the circular tank 1 facing the front lower part of each stacked live fish storage frame 15, and each water discharge pipe 16 is connected to each live fish chamber 13 of the live fish storage frame 15. Correspondingly, a water outlet 17 is provided to protrude obliquely upward, a hose 19 extending from the submersible pump 5 is connected to a communication pipe 18 communicating with each water outlet pipe 16, and a lid 20 is attached to the top surface of the circular tank 1. This is the transportation link 21.

Next, the effects of the present invention will be explained with reference to embodiment figures.

Any number of live fish transport tanks 21 can be installed on the bed of a truck for long-distance transportation.The live fish storage frames 15 are taken out from the compartments 9 of each circular tank 1 and placed in the compartments 9 and 9 of the circular tank 1. Seawater is poured into the filtering chamber 2 up to the upper end of the filtration chamber 2, and then live fish such as sea bream, yellowtail, etc. are stored in each live fish chamber 13 of each live fish storage frame 15 with the widened front part serving as a head. Then, a frame mold 14 is fitted onto the upper surface, and the live fish storage frames 15 containing each of the live fish are immersed in seawater in each compartment 9 and stacked in about four stages.

If the compartment 9 is wide, the live fish storage frame 15 may be divided into two parts at the center and arranged side by side, and the embodiment diagram shows two parts.

After storing the live fish storage frame 15 in each compartment 9, a lid 20 is fitted on the top surface of the circular tank 1, and when the switch of the submersible pump connected to the truck's power circuit is turned on, the filtration chamber 2
The seawater in the lower water chamber 4 is passed through the hose 19 and the communication pipe 18 to the water discharge pipe 16 on the inner wall of the circular tank 1,
Fresh seawater is sprayed from the water outlet 17 of the water discharge pipe 16 toward the mouths of the live fish housed in each live fish chamber 13 of the live fish storage frame 15.

Therefore, the live fish in the live fish storage frame 15 can always breathe fresh seawater, so even if transported over long distances for a long time, the freshness does not decrease, and the yield can be improved. The discharged seawater flows slightly upward toward the filtration chamber 2, overflowing into the filtration chamber 2, and waste products excreted by live fish are captured by the filter material 6 of the filtration chamber 2, and fresh seawater is produced. The ice is allowed to flow down into the lower ice chamber 4 and recirculated.

The shape of the tank is also circular, with a filtration chamber 2 in the center and a fan-shaped compartment 9 around the filtration chamber 2 to make it more compact, increasing the amount of live fish transported to the bucket relative to the amount of seawater. The conventional 8 to 12t large truck is 1200 to 150
What used to be transported was 0 animals, but now even a 6t medium-sized truck can transport 11 animals.
It is possible to transport up to 100 fish, and the transportation time can be extended to 60 hours, which greatly reduces transportation costs and enables the supply of delicious live fish to remote areas at low cost. It is effective.
