Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view schematically showing an anti-rolling system of a fishing boat according to an embodiment of the present invention.

Referring to FIG. 1, the anti-rolling system 100 of a fishing boat according to an embodiment of the present invention includes a connection unit 120 connecting two or more live fisheries 110 and two or more live fisheries 110. I can.

The live fish window 110 may have a box shape containing seawater for storing live fish harvested from fishing boats. The live fish window 110 may include a first live fish window 111 provided on the left side of the fishing boat and a second live fish window 112 provided on the right side of the fishing boat. In the present embodiment, it has been described that the live fish tanks 110 are provided one at the left and the right side of the fishing boat, but two or more live fish catches 110 may be provided depending on the size of the fishing boat. For example, in the live fish window 110, two fish tanks may be provided on the left side and two fish tanks may be provided on the right side. Such a live fish window 110 may or may not have a seawater inlet and an outlet. However, when the fishing boat operates, the seawater stored in the live fish tank 110 is not separately adjusted.

The connection part 120 spatially connects the first live fish window 111 provided on the left side of the fishing boat and the second live fish window 112 provided on the right side of the fishing boat. The connection part 120 may have a shape through which seawater stored in each of the first live fish window 111 and the second live fish window 112 can move with each other. At this time, the through-hole shape may be, for example, a cylindrical or square column shape, but is not limited to a specific shape, and any shape having a through hole through which seawater can move may be used. Such a connection part 120 may form a U shape together with the first live fish window 111 and the second live fish window 112 provided on the left and right sides of the fishing boat, respectively, and accordingly, the external environment, for example, For example, even if a rolling phenomenon occurs on a fishing boat due to wind or the like, the balance of the fishing boat can be stably maintained.

A first mesh 121 and a second mesh 122 may be disposed in the connection part 120. More specifically, the first net 121 may be disposed in the connection part 120 adjacent to the first live fish window 111, and the second net 122 is the connection part 120 adjacent to the second live fish window 112 Can be placed within. Due to the first net 121 and the second net 122, the live fish stored in the first live fish window 111 is moved to the second live fish window 112 or the live fish stored in the second live fish window 112 is the first It can be prevented from moving to the live fish window 111. On the other hand, in an embodiment of the present invention, it has been described that two nets 121 and 122 are disposed on the left and right sides of the connection part 120, respectively, based on the central part, but it is not limited thereto and two or more may be disposed. have. In addition, the first net 121 and the second net 122 may be deleted because they are not essential components constituting the anti-rolling system 1000 of a fishing boat according to an embodiment of the present invention.

In general, anti-rolling methods for reducing and controlling the rolling phenomenon in ships or fishing vessels can be classified into a passive type that does not use power and an active type that uses power.

The passive anti-rolling has the advantage of being simple because it does not require a separate power, but there is a disadvantage that the rolling phenomenon is more severe because anti-rolling is not performed in the frequency range outside the inherent rolling period of a ship or fishing boat.

Active anti-rolling was developed to compensate for this problem. The active anti-rolling method is to change the rolling cycle while opening and closing by installing an air valve, or by installing a pump to control the pump operation while changing the rolling cycle. . However, there is a disadvantage in that it is difficult to install a pump or an air valve due to space constraints in applying the active anti-rolling to a fishing boat as in the exemplary embodiment of the present invention.

Therefore, it is preferable to apply passive anti-rolling in the case of fishing boats as in one embodiment of the present invention. As described above, in the case of passive anti-rolling, since it is difficult to perform anti-rolling in response to the rolling cycle, Accordingly, a separate device capable of reducing the rolling phenomenon is required. Accordingly, the anti-rolling system 100 of a fishing boat according to an embodiment of the present invention detects a rolling cycle and controls the anti-rolling delicately in response thereto. ) May be further included.

The adjustment unit 130 may be installed in the connection unit 120 connecting the first live fish window 111 and the second live fish window 112. More specifically, the adjustment unit 130 may be installed in a central region within the connection unit 120. The adjustment unit 130 may be coupled to the connection unit 120 by a welding method, and may be installed to be detachable to facilitate maintenance and repair. This adjustment unit 130 is designed to compensate for the inclination of the fishing boat. To this end, the adjustment unit 130 may include a base portion having a plurality of holes and an opening/closing portion capable of opening and closing the plurality of holes. The control unit 130 is electrically connected to the control unit 150 that controls the operation of the opening/closing unit to reduce the rolling phenomenon of the fishing boat by the control unit 150.

The sensing unit 140 may be a rolling cycle sensing unit that detects a rolling cycle of a fishing boat. Here, the rolling cycle refers to seawater stored in each of the first live fish window 111 and the second live fish window 112 through the connection unit 120 to the first live fish window 111 and the second live fish window 112. It means the time it takes for one round trip left and right. The detection unit 140 is electrically connected to the control unit 150 and is configured to transmit a result detected by the detection unit 140 to the control unit 150. In an embodiment of the present invention, the sensing unit 140 has been described as a sensing unit that detects a rolling period, but may be a rolling angle sensing unit that detects a rolling angle of a fishing boat.

The control unit 150 serves to control the overall operation of the fishing boat, and in particular, serves to control the operation of the control unit 130 in response to receiving the detected result from the detection unit 140. More specifically, the control unit 150 selectively opens and closes a plurality of holes installed in the adjustment unit 130 when the result value transmitted from the detection unit 140 is out of a predetermined range of a preset reference rolling period.

2 is a view for explaining a method of controlling the rolling phenomenon of the anti-rolling system of a fishing boat according to an embodiment of the present invention.

Referring to FIG. 2, when the rolling phenomenon begins on the fishing boat, the seawater stored in each of the first live fish tank 111 and the second live fish tank 112 moves through the connection unit 120, resulting in a phase difference between the movements of the seawater. Occurs. At this time, the seawater is in a direction opposite to the direction (a) in which the fishing boat is inclined with respect to the center line (C) along the connection part 120 connecting the first live fish window 111 and the second live fish window 112. It will move back and forth. In this way, when the fishing boat is inclined, the load is applied in the opposite direction (b), so that the inclination of the fishing boat is minimized, so that the fishing boat is anti-rolling.

In general, in a fishing boat, a predetermined amount of seawater is stored in the fishing pod 110 according to the rolling cycle of the fishing boat. That is, it would be desirable to store the same amount of seawater in each of the first live fish window 111 and the second live fish window 112. In this case, the rolling cycle of seawater stored in the fishing pod 110 may be changed according to the width W of the fishing pod 110 and the height h of seawater filled in the fishing pod 110. At this time, the first live fish window 111 and the second live fish window 112 are designed to have the same width W. However, the width W of the fishing trough 110 is a value that is fixed once the fishing boat is designed. Accordingly, in general, the rolling cycle of a fishing boat is determined in consideration of the height h of seawater filled in the fishing tank 110, the weight of live fish filled in the fishing tank 110, and the weight of cargo mounted in the fishing boat.

By predicting these conditions in advance, when designing a fishing boat, the rolling cycle of the fishing boat is set in advance. For example, when the rolling cycle of the fishing boat is determined to be 10 seconds, the reciprocating cycle of seawater filled in the first live fish window 111 and the second live fish window 112 must be adjusted to be similar to 10 seconds.

At this time, the reciprocating period of seawater may adjust the rolling period of the fishing boat by changing the height h of seawater filled in each of the first and second live fisheries 111 and 112.

3 is a view for explaining the structure of the control unit of the anti-rolling system of a fishing boat according to an embodiment of the present invention.

Referring to FIG. 3, the adjusting part 130 of the anti-rolling system 1000 of a fishing boat according to an embodiment of the present invention may include a base part 131 and an opening/closing part 132.

The base part 131 has a plurality of holes 131H, and each hole 131H may be opened and closed by the opening/closing part 132. In this case, the sizes of the plurality of holes 131H formed in the base portion 131 may have different sizes. For example, if the first hole has a first size S1, the second hole may have a second size smaller than the first size S1. Accordingly, the anti-rolling system 1000 of a fishing boat according to an embodiment of the present invention can respond to a delicate rolling cycle due to the opening and closing of a plurality of holes 131H having different sizes.

The plurality of holes 131H formed in the base portion 131 may be selectively opened and closed. More specifically, the plurality of holes 131H formed in the base portion 131 are operated in an open state during fishing boat operation, but when a severe rolling phenomenon occurs, only some of the plurality of holes 131H may be operated in an open state. The selective opening and closing of the plurality of holes 131H may be opened and closed by the control of the controller 150.

The plurality of holes 131H formed in the base portion 131 may be independently opened and closed. More specifically, an opening/closing part 131 capable of opening and closing each hole 131H may be disposed to correspond to each hole 131H.

4 is a view for explaining an anti-rolling control method of a fishing boat according to an embodiment of the present invention.

Anti-rolling control of a fishing boat according to an embodiment of the present invention may be performed by the control unit 150.

Referring to FIG. 4, when the fishing boat starts to operate, the control unit 150 receives the result of the detected rolling cycle from the detection unit 140 (S410).

The control unit 150 determines whether the rolling cycle sensed by the sensing unit 140 is the same as the preset rolling cycle according to the design of the fishing vessel (S420), and then the detected rolling cycle value is a value greater than the preset rolling cycle +a. It is determined once more whether or not (S430). In this case, the value a may be a value at which the occupant on board the fishing boat feels that a severe rolling phenomenon occurs.

As a result of the determination, if it is determined that the rolling cycle value sensed by the sensing unit 140 is larger than the preset rolling cycle value, it is determined that there is a severe rolling phenomenon in the fishing boat, and a plurality of holes (131H) formed in the adjustment unit 130 Some of the holes of the first size S1 and some of the holes of the second size S2 are selectively closed (S440).

On the other hand, if it is determined that the rolling cycle value sensed by the sensing unit 140 is the same as or similar to the preset rolling cycle, it is determined that there is no severe rolling phenomenon in the fishing boat, and all of the plurality of holes 131H formed in the control unit 130 are Keep the fishing boat open (S470).

Thereafter, the control unit 150 determines in which range the detected rolling cycle value of the fishing boat is in (S450), and when it is determined to be a value between the preset value and the preset value + a, the first size (S1) is greater than the first size (S1). Only the hole of the second size (S2) having a small size is opened and delicately controlled (S460).

On the other hand, the control unit 150 determines in which range the detected rolling cycle value of the fishing vessel is in (S450), and if it is not determined to be a value between the preset value and the preset value + a, the preset rolling cycle and detection are performed. It is determined once again whether the resulting rolling period is the same or similar (S420) to control the adjusting unit 130.

Thereafter, when it is determined that the severe rolling phenomenon occurring in the fishing boat has been reduced, the control unit 150 opens both the hole of the first size S1 and the hole of the second size S2 to operate (S470).

In one embodiment of the present invention, when the fishing boat is running, all the holes 131H of the adjustment unit 130 are operated in an open state. Accordingly, when it is determined that a severe rolling phenomenon has occurred in the fishing boat, the opening and closing of the plurality of holes 131H is controlled according to a range outside the preset rolling period. In this way, the anti-rolling control method of a fishing boat according to an embodiment of the present invention delicately controls the rolling of the fishing boat by determining how far it deviates from a preset rolling period and selectively opening and closing a plurality of holes 131H accordingly. can do.
