Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a submersible and upwardly-type feeding apparatus for a marine-aquaculture with a regulating function of inner pressure,

The present invention relates to a water cage which is capable of culturing various fishes at high density from the sea by installing a cage net dividing a fish culture space in coastal waters, A feed storage tank in which a floating feedstock is stored can be placed on the seafloor so that the feed can be fed into the cage net in an upwardly dispersed manner, Pressure regulating water-based upward feed supply device capable of compensating for a decrease in internal pressure of a storage tank by air pressure discharged from a high-pressure gas tank.

Generally, a water cage is a facility where a cage net is installed in a water area such as a coastal area or an offshore area to cultivate various fish in a high density. Recently, There is a tendency that the cage facilities are transferred to the deep sea.

Since the seawater inside and outside the cage can freely pass through the mesh of the cage net, the water cage as described above smoothly exchanges seawater and supplies oxygen, and the waste generated in the metabolic process of aquaculture fish passes through the cage net It is not necessary to separately remove waste products because it is discharged automatically and provides various advantages in terms of large-scale aquaculture, such as that the water quality in the cage does not deteriorate even if a large amount of fish are cultured at a high density.

In the aquaculture cage as described above, it is necessary to supply the food (feed) of aquaculture fish with a certain period as in the aquaculture facility, and when the aquarium cage is installed in the water not far from the land, However, if the aquaculture cage is installed on the outer sea far from the land, the operation of the feeder is costly.

Therefore, there is a feeding device that feeds the feed in a fixed cycle to the water cage of the outer sea. Such a feeding device is a method of feeding the feed in a downward dropping manner in a floating state around the water cage , It causes undesirable problems in terms of inducing uniform growth among cultured fishes.

In other words, since most of the feeds fed to aquaculture are floated with low specific gravity, most of the feed introduced by the down-fall method stays on the surface of the water, so only the healthy ones swim to the surface quickly And the relatively fragile individuals, which are relatively inactive, will eat fewer feeds.

In order to prevent the above-mentioned situation, when the sedimentation feed of the high-boiling water sinking into the seawater is input, it is not preferable from the viewpoint of digestion and development of the aquaculture fish as compared with the soft low specific gravity feed, The waste of unnecessary feed is caused because the remaining amount of the net is passed through the bottom net of the relatively large mesh net to the outside of the mesh net.

On the other hand, if the feeding device is floated around the water cage, the feeding pipe connecting the feeding device and the cage net of the water cage is severely rocked due to factors such as waves, Not only the connection portion of the feeding pipe is easily broken, but also various mechanical parts used for feeding the feed are shaken together with the feeding device while being embedded in the casing for the device, so that frequent failure or malfunction of the feeding device is caused There was a problem.

Particularly, since the internal space of the feed storage tank including the feed feed pipe and the feed discharge pipe is formed as an enclosed space, moisture and moisture are prevented from entering the outside, so that the floating feed stored in the feed storage tank continuously maintains the dry state Thereby preventing the feed ingredients from sticking to each other and compensating for the decrease in internal pressure generated during the discharge of the feed from the feed storage tank by the air pressure injected from the high pressure gas tank, Effect.

5 shows a state in which the control unit 20 is installed on the upper end of the feed pipe 13. The control unit 20 includes a buoy body 21 for generating a predetermined buoyancy, A controller 23 including a battery 22 and an operation panel 39 and a circuit board 23 connected to the controller 23 are provided in the buoy body 21 in a watertight manner, And a cable line 25 extending from the circuit board 24 through the bodice body 21 is connected to each valve mechanism and pump mechanism including the gas injection valve 37a 18.

A feed hole 13 is formed at the center of the control buoy 20 so that the feed inlet pipe 13 itself becomes the center axis of the control buoy 20 so that the flow of the control buoy 20 The control unit 20 may be provided on the side of the feed inlet pipe 13 or on the side of the upper buoyancy pipe 3 of the cage net 2 in order to prevent the breakage of the cable line 25, It is also possible to install the control buoy 20 in a separate independent float structure.

The charging port 22a is provided in the battery 22 so that the battery 22 can be charged using a charging mechanism of the ship when the battery 22 is exhausted.

As shown in FIG. 1, the central portion of the feed pipe 13 is a flexible pipe 13a having a predetermined length and is integrally and solidly connected to the remaining metal pipe portion, It is preferable that the feed inlet pipe 13 is more securely protected by the pivotal movement of the control valve 20 and the impact generated when the control valve 20 collides with the vessel.

The flexible tube 13a may be formed in the form of a corrugated pipe as shown in the drawing or may be a flexible material such as a hose made of rubber or synthetic resin. In the case where such a flexible tube 13a is used, It is needless to say that the control unit 20 can be fixedly mounted on the upper side of the feed pipe 13 and the water pipe on the connection part of the flexible pipe 13a.

In the feed supply apparatus 10 according to the present invention, the actual feeding process of the feed is performed by setting the internal pressure of the vacuum composition pipe 17 to a negative pressure using the pump mechanism 18, After the mechanism is opened, the feed stored in the feed discharge pipe 14 having a pressure condition higher than the minimum atmospheric pressure is discharged to the vacuum composition pipe 17, and then the valve mechanism of the feed distribution pipe 15 is closed again, The valve mechanism of the pipe 19 is opened and seawater is introduced into the vacuum composition pipe 17 so that the floating feed stored in the vacuum composition pipe 17 rises to the side of the cage net 2 with seawater.

Therefore, the valve mechanism installed in the feed water distribution pipe 15 and the seawater feed pipe 19 can be used in seawater and the inlet and the outlet of the vacuum composition pipe 17 can be sealed at a level that allows airtightness. Various valve mechanisms such as a butterfly valve and a ball valve may be applied, and a pump mechanism 18 installed in the vacuum composition pipe 17 and a vacuum pump capable of being used in seawater may also be applied.

However, when the butterfly valve is used as the valve mechanism, the valve plate is located at the center of the feeding and floating passages of the feed, It is difficult to ensure airtight performance at a level that allows the interior of the ball valve to be formed with negative pressure. In the case of using a ball valve, it is possible to feed feed, There is a disadvantage that relatively large power is required.

Therefore, in the present invention, a valve mechanism conforming to the object of the present invention is newly devised and applied instead of the general valve mechanism, while a smooth distribution of feed through the vacuum composition pipe 17 and a floating of the feed due to the input of seawater The present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the scope of the present invention.

The valve plate 26 is provided at the outer side (upper side in the drawing) A valve driving portion 16 for operation is provided.

The valve driving unit 16 includes a driving motor 28 having a speed reducer 28a and a screw jack 29 interlocked with the speed reducer 28a inserted in the waterproofed driving unit casing 16a, The screw jack 29 is fixedly mounted on a mounting bracket 29a inside the driving unit casing 16a and a feed screw 30 reciprocating according to the operation of the drive motor 28 is installed in the screw jack 29 And the front end portion of the feed screw 30 passes through the drive section casing 16a and the feed distribution pipe 15 to open and close the valve plate 26 in the closing direction 30a ).

The valve seat 27 is a funnel-shaped pipe whose inner diameter is gradually narrowed (thickened) along the feeding direction of the feed, so that the inlet side of the valve seat 27 It is preferable that a seat pad 27a made of rubber or synthetic resin is attached to the side of the valve plate 26 on the close contact surface (right side in the drawing) so as to maintain airtight performance.

The hinge engaging portion 26a of the valve plate 26 is inserted into the valve seat 27 so that the opening and closing end 30a of the conveying screw 30 is in direct contact with the surface of the valve plate 26. [ The valve plate 26 is allowed to perform the angular movement in the opening direction with elasticity by means of a coil spring or the like so that the closing operation of the valve mechanism by the valve driving unit 16 It is preferable to maintain the valve plate 26 in an open state before performing the above operation.

The portion where the opening and closing end 30a of the feed screw 30 passes through the drive portion casing 16a and the feed distribution pipe 15 and the portion where the cable line 25 for the drive motor 28 penetrates the drive portion casing 16a It is preferable to apply the waterproof packing kits 25a and 30b for watertight processing to each of the opening and closing ends 30a and 30b. It is preferable that an inflection point portion of the feed distribution pipe 15 serving as an elbow pipe is installed.

According to the above-described method, when the valve mechanism in which the delivery screw 30 is moved to the open position (upward in the figure) as shown by the imaginary line in Fig. 6, the valve plate 26 is moved to the hinge engagement portion The feeding passage of the feed can be sufficiently secured by feeding the feed into the vacuum composition pipe 17 after the feeding of the feed into the vacuum composition pipe 17 is completed, The closing operation of the valve plate 26 is also performed in such a manner that almost no feed is left around the valve seat 27 because the feed is dispersed along the downwardly curved surface of the valve seat 27 and the feed outlet pipe 14 and the vacuum composition pipe 17 Can be performed smoothly.

8 and 9 show a vacuum composition pipe 17, a seawater supply pipe 19, a pump mechanism 18 and a valve mechanism applied to the vacuum composition pipe 17, the vacuum composition pipe 17, The feed distribution pipe 15 and the vacuum composition pipe 17 are connected to each other in such a manner that the feed discharge pipe 14 and the seawater supply pipe 19 are formed in a & Provides a connecting piping joint structure.

The seawater supply pipe 19 is provided with a rectangular passage through which a circular pipe is connected to the upper side and the lower side, and a circular pipe at the lower side is vertically connected to the upper end side of the vacuum composition pipe 17, Is connected to the lower end side of the feed pipe 14a and is connected to both ends of the vacuum composition pipe 17 and the sea water supply pipe 19 with waterproof packing for water tightness interposed therebetween A flange portion is formed.

The valve mechanism provided in the seawater inlet pipe 19 has the same structure as that provided in the feed water distribution pipe 15. The only difference is that the seawater inlet pipe 19 has a rectangular passage shape, Since the opening and closing operation of the valve plate 26 is not interfered with by the passage structure, the diaphragm 27 and the valve plate 26 also have a square pipe and a rectangular plate shape. It becomes more advantageous in terms of its design and application as compared with a circular valve type valve structure such as (15).

8, the lower side of the vacuum composition tube 17 is formed in an elbow shape and the upper side of the vacuum composition tube 17 is formed in a shape that connects the respective flange portions in a linear direction. It is possible to provide a more advantageous advantage in terms of preventing the remaining amount of feed in the vacuum composition pipe 17 from remaining in the vacuum composition pipe 17 when the sea water is injected into the vacuum composition pipe 17 to float the feed. have.

The pump mechanism 18 provided outside the vacuum composition pipe 17 is provided with a pump motor 31 and an impeller 32 interlocked with the pump motor 31 in a watertightly processed pump casing 18a, The suction pipe 33 of the impeller 32 is connected to the vacuum composition pipe 17 and the discharge pipe 34 of the impeller 32 extends through the pump casing 18a and extends to the outside, The waterproof packing 25a for watertight processing is interposed in the portion of the cable line 25 for the watertight connector 31 through the pump casing 18a.

More preferably, the suction pipe 33 of the impeller 32 is connected to the inflection point portion of the vacuum composition pipe 17 serving as an elbow pipe, so that when the pump mechanism 18 discharges seawater and forms a negative pressure, A drawing wire 33a for preventing the feed ingredient from flowing into the impeller 32 is provided at the inlet side of the suction pipe 33 of the impeller 32 and the discharge pipe 33a of the impeller 32 34) is provided with a check valve 34a for preventing reverse flow of seawater.

The vacuum sensor 35 is installed inside the vacuum composition pipe 17 and the vacuum sensor 35 is connected to the control line 20 together with the cable line 25 for the pump motor 31. [ The vacuum sensor 35 can measure the degree of the negative pressure during the seawater discharge and the negative pressure composition work by the pump mechanism 18 and stop the pump motor 31 at an appropriate time point The timing at which the gas injection valve 37a of the high-pressure gas tank 36 and the valve mechanism of the feed water feed pipe 15 and the seawater feed pipe 19 are operated can also be determined as the vacuum sensor 35. [

1 and 10, the feed pipe 14a connected to the upper end of the seawater feed pipe 19 is connected to the lower side center portion of the cage net 2 from the seawater feed pipe 19, That is, to extend under the center of the bottom net 2a, to perform an upwardly dispersed feeding of the feed through the inside of the cage net 2.

The reason why the feed can be supplied even if the feeding pipe 14a is not penetrated into the cage net 2 as described above is that the conventional bottom net 2a applied to the cage net 2 can be fed to the cage net 2 The feed discharged through the feed supply pipe 14a is fed through the mesh of the bottom net 2a to the side of the net 2 through the net of the bottom net 2a because the size of the mesh is relatively large, Because it can float inside.

Even if the cage net 2 is installed by using the anchor rope 7 as shown in Fig. 1, the cage net 2 swings in the front, rear, left, and right directions along the direction of the tide The upper end outlet portion of the feed pipe 14a is positioned at the center of the bottom net 2a of the cage net 2 in consideration of such a swinging width so that even if the cage net 2 swings to some extent, It does not cause any disruption to the supply.

More preferably, the feed pipe 14a itself is made of a flexible hose, and a flange pipe 8a (19a) made of metal or plastic is integrally connected to the upper end side and the lower end side of the feed pipe 14a The upper end side flange tube 8a of the feed feed pipe 14a is radially connected to the lower end periphery of the cage net 2, that is, the lower reinforcement frame 5, by means of a plurality of center ropes 8, 14a are connected to the seawater inlet pipe 19. The lower end flange pipe 19a is connected to the seawater inlet pipe 19.

Even if the swing width of the cage net 2 by the algae is increased to some extent, the feed pipe 14a of a flexible material is formed on the side of the center of the bottom net 2a together with the center rope 8 The feeding position of the feed can be prevented from being largely shifted from the center of the bottom net 2a and the feeding position of the feed can be prevented from being deviated from the center of the bottom net 2a in the event of an emergency such as red tide or typhoon.

Hereinafter, a process of supplying feed into the cage net 2 of the marine cage 1 using the feed device 10 according to the present invention will be briefly described with reference to FIGS. 1 and 10. FIG.

First, the feed device 10 according to the present invention is installed on the bottom surface in the manner as shown in FIG. 1, and then the feed tube cover 13b is opened to feed the floating feed to the feed feed tube 13 A predetermined amount of feed is stored in the feed storage tank 11 while some of the feed is fed through the feed outlet 11c along the inclined bottom surface 9 of the feed storage tank 11 After the feeding of the feed is completed, the feed tube cover 13b is closed to close the inlet of the feed tube 13.

When the feeding time of the feed is reached in the state where the feeding device 10 of the present invention is set in the above manner, the controller 23 judges this and feeds the pump mechanism 18 of the vacuum composition pipe 17 In this case, the valve mechanism of the feed distribution pipe 15 and the seawater inlet pipe 19 is constructed so as to be in a negative pressure state in the vacuum composition pipe 17, And the degree of vacuum of the vacuum composition pipe 17 is determined by the vacuum sensor 35 and the operation of the pump motor 31 is stopped at an appropriate time.

The controller 23 opens the valve mechanism of the feed distribution pipe 15 so that the feed pipe 14 is opened under the pressure condition of at least the minimum atmospheric pressure, The amount of feed fed into the vacuum composition pipe 17 is supplied from the feed storage tank 11 to the feed pipe (not shown) through the feed pipe 15, The controller 23 opens the gas injection valve 37a of the high pressure gas tank 36 for a short period of time so that the feed storage tank 11, So that the decrease in the internal pressure of the engine can be compensated by the air pressure.

When feed is fed from the feed discharge pipe 14 to the vacuum composition pipe 17 through the feed pipe 15 and the internal pressure of the vacuum composition pipe 17 is equal to the minimum atmospheric pressure, The vacuum sensor 35 of the composition pipe 17 senses this and transmits a signal to the controller 23. The controller 23 closes the valve mechanism of the feed distribution pipe 15 based on the signal , The valve mechanism of the seawater inlet pipe 19 is opened.

As described above, when the valve mechanism of the seawater inlet pipe 19 is opened, the seawater staying in the feed pipe 14a flows into the interior of the vacuum composition pipe 17 through the seawater inlet pipe 19, The seawater is introduced into the feed pipe 14a so that seawater is filled in the vacuum composition pipe 17, the seawater feed pipe 19 and the feed pipe 14a. As a result, Is floated along the seawater feed pipe 19 and the feed pipe 14a.

As shown in FIG. 10, the feedstuffs floating along the seawater feed pipe 19 and the feed pipe 14a are fed from the outlet side of the feed pipe 14a through the bottom net 2a to the inside of the cage net 2 And the entire feeding process of the feed is repeatedly performed in accordance with the feeding time input to the controller 23, so that the feeding of the feed can be automatically performed.

As described above, the feed supply device 10 according to the present invention feeds upward from the feed storage tank 11 seated on the seabed surface toward the inside of the cage net 2, which is most suitable for feeding the aquaculture fish , So that most of the cultured fish distributed from the inner bottom layer to the middle and upper part of the cage net (2) can uniformly feed the feed, and thus, the uniform growth of the aquaculture fishes and the commercialization Improvement can be achieved.

Particularly, since the internal space of the feed storage tank 11 including the feed inlet pipe 13 and the feed discharge pipe 14 is formed as a closed space, moisture and moisture are prevented from flowing into the feed storage tank 11, The feedstock stored in the feed storage tank 11 is kept in a dry state so that the feed components do not adhere to each other and the internal pressure reduction occurring in the process of discharging the feed from the feed storage tank 11 is suppressed by the air pressure So that more stable and smooth feeding can be performed.

In addition, it is possible to reduce the cost and manpower required for feeding management by automatically feeding feeds using the feed distribution pipe 15, the vacuum composition pipe 17 and the seawater feed pipe 19, while the floating feed So that unnecessary waste of feed can be reduced, and piping and mechanical parts necessary for feeding the feed can be supplied to the feed storage tank 11 So that the failure or malfunction of the feed device 10 due to the wave or the like can be prevented in advance.
