BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a transport container, and more particularly, to a transport container, which is adapted to convert an interior of a freezer container to create an environment in which a live fish such as a live fish can survive, The present invention relates to a container for transporting goods.

In general, live fish refers to fish and shellfish such as fish, shrimp, shellfish, and water squid that go live during their distribution. These live fish can be supplied to consumers by being transported by live fish from the production area to the sale place.

A live fish car is a vehicle intended to carry fish and crustaceans in the mountain state.

Since the fish are transported to the acid state, the fish are liable to be killed by the fecal matter of the fish during transportation, the contamination of water by ammonia as ammonia, the deficiency of air, and the temperature rise. Therefore, in order to transport aquatic products in a fresh state for a long distance, a live fish car is usually equipped with a water tank, an air or air introducing device, and a purifier such as water or seawater.

One example of such a live fish car is proposed in Patent Application No. 10-2009-95369 (name: container for live fish transportation), wherein a container for a protein skimmer, a freezing unit, a filter material, a sterilizing device, It is a structure capable of long-distance transportation of live fishes by mounting a feeding device.

However, the conventional live fish has the following problems.

First, since the water tank is fixed to the inside of the container, the container can be used only for live transportation, resulting in poor usability.

Second, if a pump is installed to circulate live fish in the tank, there is a danger of electric leakage or electric shock.

Third, the air supply unit is connected to the external power supply or the battery in a serial manner, and there is a problem that it is difficult to supply air when an external power supply or a battery fails.

Fourth, fishes such as shellfish are transported in a sinking state on the bottom of a tank, so that the air supplied to the inside of the tank rises after being supplied to the tank, so that it is difficult to supply enough water to the bottom of the tank. There is a problem that freshness is difficult to maintain.

Fifth, there is a problem that seafood such as shellfish sink on the bottom of the tank, so that it can be pressed by other aquatic products.

Sixth, since the bottom of the water tank is flat, it is difficult to completely discharge the live fish water on the floor when the water is discharged from the water tank to the outside.

Seventh, there is a problem that a separate pump is required if the heat exchanger is installed outside the water tank, and the heat exchanger itself is cooled down when the water pump fails.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a container for live fish transportation according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figs. 1 to 13, the transport container 3 proposed by the present invention comprises a container 3; At least one water tank (5) disposed inside the container (3) and storing aquatic products; A heat exchanger 7 for appropriately controlling the temperature of the water tank 5; An air supplier (9) for supplying air to the water tank (5); Then, air is injected into the lower part of the circulation pipe 31, which is disposed in the water tub 5 and is raised to the living water in the circulation pipe 31 by flowing air into the lower part of the circulation pipe 31 into which the living fish water flows, And a circulation part 11 which can be rotated.

In the transport container 3 having such a structure, the container 3 is formed with a certain space therein, and the devices such as the water tank 5, the heat exchanger 7, and the air supplier 9 may be arranged.

The number of the water tanks 5 may be one or a plurality, and may be appropriately selected according to the size of the container 3. In this water tank 5, a space having a certain volume is formed therein, so that the living fish can be stored and aquatic products such as live fish can be stored.

The water tank 5 is provided with a lid C on the upper part so that aquatic products such as live fish and live fish water can be supplied or taken out to the inside of the water tank 5 through the lid C as well.

2 and 3, the water tank 5 is formed such that one side of the bottom 45 is inclined and the side drain 21 is formed to discharge the living water of the water tank 5, It is possible to discharge the small amount of live fish water tank 5, which has been stored in the storage tank 45, to the outside. At this time, the drain valve (V) is attached to the side drain hole (21), so that the drain valve (V) is appropriately opened and closed so that the drainage work can be efficiently performed.

A heat insulating material 47 is provided in the lower part of the water tank 5 so that the lower part of the water tank 5 is separated from the bottom of the container 3 by a predetermined height so that the temperature of the live water stored in the water tank 5 3) can be minimized.

As described above, the water tank 5 has the advantage that the temperature of the running water can be kept constant by arranging the heat insulating material 47 on the bottom 45 and inclined to one side, and the running water can be discharged smoothly.

As shown in FIG. 4, the bottom 45 of the water tub 5 is formed in a double structure, so that it is possible to sufficiently supply the air to the aquatic products sinking on the bottom, such as shellfish.

The piercing plate 40 is installed on the inner bottom of the water tub 5 and supported by the support 43 to form the space 42 at a predetermined distance from the floor. A plurality of holes (h1) are formed in the perforated plate (40), so that air and live fish can pass through the perforated plate (40).

Therefore, when air is supplied into the water tub 5, the air supplied to the bottom is collected in the space 42 formed between the perforated plate 40 and the bottom, The oxygen saturation with respect to the number of living fish in the space 42 is increased.

As a result, aquatic products such as shellfish are placed in the space 42 formed between the pier 40 and the bottom. Since the oxygen saturation is high in the space 42, shellfish and the like are fresh Lt; / RTI >

At this time, since the perforated plate 40 is separable from the water tank 5, when the shellfish is settled on the floor, the perforated plate 40 is separated and then the shellfish is inserted and the perforated plate 40 is again connected to the water tub 5 .

In addition, the perforated plate 40 may be entirely composed of one piece and disposed in the water tank 5, but it may be divided into four zones.

5, the air supplier 9 can be installed in the container 3 to supply the air to the water tub 5. As shown in Fig. The air supply 9 includes an air storage tank 22; A first disperser (27) connected to the air storage tank (22) for supplying air to the bottom edge of the water tank (5) and injecting the air; And a second disperser (29) connected to the air storage tank (22) for supplying air to the inside of the water tank (5) and injecting the air.

In the air supplier 9 having such a structure, the air storage tank 22 may be configured in various ways, but is preferably composed of two low-pressure supply tanks 23 and one high-pressure supply tank 25.

Two low pressure supply tanks 23 supply air to the first disperser 27 and one high pressure supply tank 25 supplies air to the second disperser 29. The low-pressure supply tank 23 and the high-pressure supply tank 25 are connected to different power sources.

For example, the low-pressure supply tank 23 is connected to the main power source, and the high-pressure supply tank 25 is connected to the battery of the container 3 itself. Therefore, even if the operation of the low-pressure supply tank 23 is stopped due to the shutdown of the main power, the high-pressure supply tank 25 can be continuously operated by the battery, so that the fish can be prevented from being killed due to the power failure.

The first disperser 27 is disposed at each of the four edges of the bottom of the water tank 5 and the spray hole h0 is formed on the surface thereof so that air can be injected into the water tank 5. [ At this time, the size of the injection hole h0 may be variously formed, for example, 300 microns or less. As described above, since the injection hole h0 is made small, oxygen can be sufficiently supplied even with a small amount of electricity, so that the degree of oxygen saturation can be maximized.

Further, the second dispersing device 29 is constituted by a plurality of dispersing devices 29, and is disposed in the middle of the water tank 5, preferably four. Therefore, a sufficient amount of air can be supplied by supplying air into the water tub 5 through the four dispersing units.

At this time, the four dispersing units may be arranged at regular intervals in all directions, but the arranging method can be appropriately modified in accordance with the size or size of the water tank 5.

Meanwhile, as shown in FIG. 6, the inside of the container 3 is provided with the heat exchanging part 7, so that the internal temperature of the container 3 can be kept at a certain level or less.

More specifically, the heat exchanger 7 is composed of a compressor 50, a condenser 52, an expansion valve 54, and an evaporator 56. The heat exchanging unit 7 is a refrigerator of a conventional structure. The compressor 50 is operated by an electric motor to compress the gaseous refrigerant, and the refrigerant is sent to the condenser 52. The refrigerant is cooled by liquefying it with water or air outside the refrigerator .

When the refrigerant in the liquid state is injected into the evaporator 56 while the flow rate is adjusted by the expansion valve 54, the refrigerant expands and vaporizes and absorbs heat from the periphery of the evaporator 56 to cool the inside of the vessel. The gasified refrigerant returns to the compressor (50) and is compressed to be in a liquid state. In this way, the inside of the container 3 can be controlled to a constant temperature through the four stages of compression, condensation, expansion, and vaporization.

7, the refrigerant L is circulated in the evaporator 57 of the evaporator 56, and the evaporator 57 is disposed in the wall of the water tank 5. As shown in Fig. A blocking member P such as a plate may be disposed outside the evaporation pipe 57.

The evaporating pipe 57 is arranged in the living water W stored in the water tank 5 to control the living water W to a constant temperature through heat exchange with the living water W circulating in the water tank 5 can do.

At this time, since the evaporation pipe 57 is disposed inside the water tank 5, the internal temperature of the water tank 5 can be more efficiently controlled.

That is, when the evaporation pipe 57 is disposed outside the water tank 5, a separate pump is required. When the pump failure occurs, the heat exchange unit 7 itself is cooled, And disposed inside the water tub 5 to overcome this problem.

Although the blocking member P is disposed outside the evaporation pipe 57 in the above description, the present invention is not limited thereto and the blocking member P may be omitted.

As shown in FIG. 8, the circulation unit 11 includes a circulation pipe 31 serving as a moving passage for live fish water; And an air pump 19 mounted on the circulation pipe 31 for moving the water.

Both ends of the circulation pipe 31 are locked to one side and the other side of the water tank 5 to a certain depth, thereby sucking the water on one side and supplying it to the other side. Therefore, the water stored in the water tank 5 can be circulated through the circulation pipe 31 to minimize water spoilage.

An air pump 19 may be applied to discharge the live fish water. The air pump 19 moves the live water by the compressed air. That is, the air pump 19 includes a compressor 35 for compressing and supplying air and a discharge pipe 37 for supplying air compressed by the compressor 35 to the lower portion of the circulation pipe 31.

Therefore, when the compressor 35 is driven, the compressed air is supplied to the lower portion of the circulation pipe 31 through the discharge pipe 37, and bubbles are generated in the circulation pipe 31, 31, the number of live fish in the circulation pipe 31 rises to a position higher than the water level of the water tank 5. [

When the compressor 35 is driven through this principle, the live fish supplied to the circulation pipe 31 from one side of the water tank 5 is moved upward by the rise of the bubbles and then supplied to the other side of the water tank 5 The living fish inside the water tank 5 can be circulated.

At this time, a sensor (S) capable of sensing the water level is mounted on the inner wall of the water tank (5), and when the water level reaches a certain height, the compressor (35) So that the living fish can be circulated by ascending through the pipe 31.

By applying a method of automatically circulating the live fish water by mounting a sensor capable of sensing the water level as described above, it is possible to prevent spoilage or the like which may occur when the live fish water is circulated in the water tank by the manual method as in the conventional method .

7 and 8, the filtration member 13 is disposed on the circulation pipe 31 to remove foreign matter contained in the living water. Such a filter member 13 may be applied to various types of filter media, for example, a filter medium such as activated carbon, loess, ceramics and the like.

Therefore, live fish water flowing along the circulation pipe 31 passes through the filtration member 13, so that fish excrement, foreign matter, and the like contained in the live fish water can be removed.

In addition, the sterilizing unit 17 may be additionally disposed on the circulation pipe 31 in addition to the filtration member 13. The sterilizing unit 17 may include various sterilization methods such as an ultraviolet sterilization method and an infrared sterilization method.

Therefore, since the sterilizing unit 17 is disposed in the circulation pipe 31, the number of live fish flowing inside the circulation pipe 31 can be sterilized by ultraviolet rays or infrared rays.

The filter member 13 and the sterilizing unit 17 are mounted on the circulation pipe 31 disposed in each water tank 5 as described above so that the living fish stored in the water tank 5 is corroded during long- .

The water tank 5 having such a structure is detachably mounted in the container 3 so that it can be loaded into the container 3 by the conveyance unit T as described above, It can be unloaded from the outside.

More specifically, as shown in Figs. 10 and 11, the transfer unit T includes a main rail r1 disposed at the bottom of the container 3; A slider S disposed on the bottom of the water tub 5 and sliding along the main rail r1; And a stopper 70 which is disposed on the main rail r1 and fixes the transported main rail r1.

The main rails r1 are preferably arranged in pairs and are spaced apart from each other by a certain distance. At this time, the main rail r1 may protrude from the bottom of the container 3, but it is preferable that the main rail r1 is disposed inside the bottom and the top surface is formed at the same or similar height as the bottom surface of the container 3. [

The slider S is mounted on the bottom surface of the water tub 5 and a concave groove 71 is formed so that the main rail r1 is inserted into the groove 71 and can be slid.

At this time, the width and the depth of the groove 71 have such a size that the main rail r1 can be inserted and slid.

Therefore, when the water tray 5 is loaded into the container 3, by applying an external force in a state where the slider groove 71 of the water tray 5 is inserted into the main rail r1, And can be loaded into the interior of the container 3 by sliding along the rail r1.

Conversely, when the water tank 5 is unloaded from the container 3, by pulling the water tub 5 in the opposite direction, the slider S slides along the main rail r1 in the outer direction of the container 3, Lt; / RTI >

At this time, the wheel may be mounted on the slider S as another embodiment of the present invention. That is, a pair of wheels are mounted on the bottom surface of the slider S, and the pair of wheels are spaced apart from each other by a predetermined distance, so that they can be respectively seated on the pair of main rails r1.

Therefore, compared to the case of loading by the groove method, it is possible to load with less force than in the case of loading the water tub 5 by the wheel system.

The auxiliary rail r2 is attached to the outer end of the main rail r1 so that the water tank 5 placed on the outer surface of the container 3 can be easily loaded on the bottom of the container 3 located at the upper side .

The auxiliary rail r2 is detachably connected to the main rail r1 disposed at the bottom of the container 3 and rotatable.

12, a connecting bracket 68 protrudes from one end of the auxiliary rail r2, and a coupling hole h2 is formed in the connecting bracket 68. As shown in FIG. The connecting bracket 68 is in contact with the side surface of the main rail r1 and the side surface of the main rail r1 is formed with a fastening hole h3 to pass through the main rail r1.

The engaging pin 69 is engaged with the engaging hole h2 through the engaging hole h3 in a state where the connecting bracket 68 of the auxiliary rail r2 corresponds to the side surface of the main rail r1, (r2) may be integrally connected to the main rail r1.

At this time, there is a slight clearance between the outer peripheral surface of the engaging pin 69 and the inner peripheral surface of the engaging hole h2 and the engaging hole h3, so that the auxiliary rail r2 can be rotated clockwise or counterclockwise.

The other end of the auxiliary rail r2 is fixed to the ground surface while one end of the auxiliary rail r2 is connected to the main rail r1 to connect the water tank 5, which is placed on the outer surface of the container 3, can be transferred to the inside of the container (3) by using the r2.

When the auxiliary rail r2 is not used, the coupling pin 69 is disassembled and the auxiliary rail r2 is separated from the main rail r1, and then stored in the container 3. [

On the other hand, since the water tank 5 is a heavy object, the carrying unit 60 may be supplementarily mounted for easier loading / unloading. That is, the carrying unit 60 includes a carrying rail r3 disposed on the ceiling of the container 3; A retractor 62 transportably mounted on the carrying rail r3 and moving forward and rearward; A connecting member (65) connected to the pulling port (62) and vertically movable up and down; And a pulling ring 66 attached to the connecting member 65 and hooked to the water tub 5.

The carrying rails r1 are arranged in a single number and are fixed to the ceiling of the container 3. A roller 64 is mounted on the upper portion of the pulling mouth 62 and rests on the carrying rail r1. Further, a pulling ring 66 is attached to a lower portion of the pulling mouth 62 to fix the water tub 5 so that it can be carried.

At this time, the bracket B is mounted on the upper part of the water tub 5 so that the pulling ring 66 can be caught. In addition, the pulling ring 66 can be connected to the pulling mouth 62 by a chain or other connecting member 65 to adjust the height of the pulling ring 66.

Therefore, when the water tray 5 is loaded into the container 3, the conveying portion 60 is pulled and moved along the conveying rail r1 in the direction of the door D of the container 3. Then, the pulling collar 66 is pulled downward and is hooked to the bracket B of the water tub 5. In this state, the water tray 5 can be loaded with a small force by moving the carrier 60 inward of the container 3.

Conversely, even when the water tank 5 is unloaded from the container 3, the water tank 5 can be unloaded by pulling the draw ring 66 to the bracket and then toward the door D of the container 3 .

As described above, the water tank 5 is not fixed to the container 3 in a built-in manner, but is unloaded to the outside of the container 3, if necessary, so that the container 3 is also used for other purposes There are advantages to be able to.

Further, in this process, the water tank 5 can be loaded or unloaded with a smaller force by using the carrying unit 60. [

In the above description, the carrying unit 60 is described as a moving object of the water tub 5, but the present invention is not limited to this, and other heavy objects other than the water tub 5 may be carried. For example, other components disposed in the live fish transport container can be carried by this transport section 60.

By disposing the stopper 70 at one end of the main rail r1, the loaded water tank 5 can be fixed to the bottom of the container 3. [

13, the stopper 70 includes a base 72 fixed to the bottom surface of the container 3; A latch 74 hingedly mounted on the base 72 to be caught or released by the latching jaw 78 of the water tub 5; And a lever (Lever) 76 for lifting the latch 74 in a clockwise or counterclockwise direction.

The stopper 70 having such a structure is configured such that when the water tray 5 is transported along the main rail r1, when the user tilts the lever 76 so that the latch 74 is caught by the catching jaw 78 of the water tray 5 The water tub 5 can be fixed at a predetermined position.

Conversely, when the water tank 5 is unloaded, the lever 76 is turned in the opposite direction so that the latch 74 is separated from the latching jaw 78 of the water tub 5, thereby releasing the water tub 5 from the fixed position It can be unloaded.

Hereinafter, the operation of the container 3 for transporting marine products according to the present invention will be described in more detail.

As shown in FIGS. 1 to 13, when a fish product such as a live fish is first transported, the water tank 5 is loaded in the container 3. The door of the container 3 is opened to load the water tray 5 and the connecting bracket 68 protruding from one end of the auxiliary rail r2 is brought into contact with the side surface of the main rail r1.

The auxiliary rail r2 is connected to the main rail r1 by engaging the engaging pin 69 with the engaging hole h2 of the connecting bracket 68 and the engaging hole h3 of the main rail r1. Therefore, the upper end of the auxiliary rail r2 is connected to the main rail r1, and the lower end thereof is fixed to the ground.

In this state, the water tray 5 is pushed up along the auxiliary rail r2 and the main rail r1 to enter the inside of the container 3.

At this time, the carrying unit 60 may be supplementarily used to load the water tank 5 with a smaller force.

The process of loading using the carrier unit 60 will be described in more detail by pulling the carrier unit 60 movably arranged on the ceiling of the container 3 to the outside of the container 3, The connecting member 65 such as a chain is lowered and the towing hook 66 is hooked on the bracket B protruded to the upper portion of the water tub 5 after reaching the upper portion of the water tub 5. The pulling hook 66 is hooked on the bracket B and the pulling ring 66 is raised and the water tray 5 is pushed to enter the inside of the container 3 along the inclined surface by the auxiliary rail r2.

By using the carrier 60 in this way, the water tray 5 can be introduced into the container 3 with a smaller force.

The water tank 5 enters the inside of the container 3 and is continuously pushed to move the water tank 5 to the fixed position. When the water tub 5 reaches the fixed position, it is fixed by the stopper 70. In other words, the lever 76 of the stopper 70 is tilted so that the latch 74 is hooked on the latching jaw 78 of the water tub 5, whereby the water tub 5 can be fixed at a predetermined position.

When the water tank 5 is fixed in this manner, the water is supplied to the water tank 5 to supply air. That is, the lid C of the water tank 5 is opened, and live water is poured into the water tank 5 through the water pipe to be stored up to a certain water level.

When the live fish reaches a certain water level, compressed air is supplied to the lower portion of the circulation pipe 31 through the discharge pipe 37 by driving the compressor of the air pump 19, and air bubbles are generated in the circulation pipe 31 , The apparent density becomes smaller than the number of external living fishes of the circulation pipe 31, so that the living fish water inside the circulation pipe 31 rises to a position higher than the water level of the water tank 5. Through this principle, the running water can circulate in the water tub 5 through the circulation pipe 31 to minimize water contamination.

The foreign matter such as excretion contained in the running water flowing along the circulation pipe 31 can be removed by the filtration member and the sterilizing unit 17.

That is, since the filtration member 13 made of activated carbon, loess, ceramics, or the like is disposed on the circulation pipe 31, foreign matter can efficiently flow through the filtration member 13 when the living water flowing along the circulation pipe 31 passes through the filtration member 13 Can be removed.

The living fish water that has passed through the filtration member 13 can be sterilized by being exposed to ultraviolet rays or infrared rays while passing through the sterilizing unit 17.

The filter member 13 and the sterilizing unit 17 are mounted on the circulation pipe 31 disposed in each water tank 5 as described above so that the living fish stored in the water tank 5 is corroded during long- .

The live fish can be controlled at a constant temperature through heat exchange with the refrigerant flowing in the evaporation pipe 57 of the evaporator 56.

In addition, when the inside of the water tank 5 is cleaned, the living water stored in the water tank 5 is discharged to the outside through the water drain valve V by opening the drain valve V mounted on the lower part of the water tank 5 . At this time, since the bottom of the water tank 5 is inclined at a certain angle, the living water inside the water tank 5 can be easily discharged to the outside.

As described above, even when aquatic products such as live fish are transported over a long distance by improving the structure of the water tank 5, it is possible to carry out transportation in a state in which decay and the like are prevented, and freshness can be maintained.
