Here, since the deck 11, the fishing net 12, the power unit and the steering unit are general configurations applied to the ship 10, detailed descriptions thereof will be omitted. The ship netting device 100 may be installed at either the bow or stern of the ship 10. In the following, a case in which the vessel netting device 100 is installed at the bow and disposed at one end in the width direction will be described as an example.

Fig. 3 is a perspective view showing a first position of a plurality of netting rollers, and Fig. 4 is a perspective view showing a second position of a plurality of netting rollers.

1 to 4, the fishing net device 100 for a ship according to an embodiment of the present invention is a device for recovering a fishing net mounted on a ship 10, and winds a main body 110 and a fishing net 12. It may include at least one netting roller 120 coupled to the main body 110 rotatably so as to be released or released, and a support 130 installed on the ship 10 and supporting the main body 110. The support 130 is a first position where a plurality of netting rollers 120 are disposed on the vessel 10 and at least one of the plurality of netting rollers 120 is outside the vessel 10. It may be configured to rotate the main body 110 between the second positions in which it is disposed. In addition, the ship netting device 100 can control the rotation angle of the cover part 140 and the plurality of netting rollers 120 that can cover the gap between the main body 110 and the plurality of netting rollers 120 A control unit (not shown) may be further included.

The main body 110 is disposed above the deck 11 of the ship 10, and may be a part constituting the body of the ship netting device 100. Referring to Figure 1, the main body 110 may be formed extending in the longitudinal direction. In the following description of the structure of the main body 110, as shown in Figure 1, the case where the main body 110 is disposed along the longitudinal direction will be described assuming. However, since the main body 110 is coupled to a support 130 to be described later and can be rotated in a counterclockwise direction as shown in FIG. 4, its arrangement direction can be changed. The main body 110 may include a body portion 111 , an insertion hole 112 and a guide frame 113 .

The body portion 111 may be a structure that extends in the longitudinal direction, has a predetermined thickness in the width direction, and has a height in the vertical direction. A connecting shaft 122 and a rotation motor 123 of the netting roller 120 to be described later may be installed in the body portion 111. In addition, the upper body 132 of the support 130 to be described later may be coupled to the body portion 111 . In the following, the side to which the connecting shaft 122 is coupled is referred to as one side of both sides of the body portion 111, and the side to which the rotation motor 123 and the upper body 132 are coupled is referred to as the other side.

In addition, the body portion 111 may include a support panel 111a for supporting the guide frame 113 . The support panel 111a is installed below one side of the body portion 111 and may be coupled to the lower portion of the guide frame 113 . For example, the support panel 111a may be provided as a plate extending in the longitudinal direction. Thus, the support panel 111a can support the guide frame 113 coupled to the body 111 from the lower side, and can distribute the load of the guide frame 113 applied to the body 111 .

The insertion hole 112 is a portion into which a fixture 132a of the upper body 132 to be described later is inserted, and may be formed concave inward from one side surface of the body portion 111. Here, the insertion hole 112 includes the first netting rollers 120a disposed on the relatively upper side of the plurality of netting rollers 120 and the second netting rollers 120b disposed on the relatively lower side in the vertical direction. can be placed in between. For example, the insertion hole 112 may be located at the center of the longitudinal length and the center of the vertical length of the body portion 111 . Since the insertion hole 112 is formed at the center of the longitudinal length of the body portion 111, it is possible to suppress or prevent the load of the body portion 111 from being biased to one side. In addition, as the insertion hole 112 is formed at the center of the longitudinal length of the body portion 111, excessive stress concentration on a specific portion of the fixture 132a inserted into the insertion hole 112 is suppressed or It can be prevented.

The guide frame 113 may guide the fishing net 12 wound around the plurality of netting rollers 120 so as not to be separated from the plurality of netting rollers 120 . The guide frame 113 is coupled to the body 111 and may be arranged to surround the plurality of net rollers 120 . The guide frame 113 may include a first frame 113a, a second frame 113b, a third frame 113c, a fourth frame 113d, and a fifth frame 113e.

The first frame 113a is coupled to the body 111 and may be disposed to surround both sides of the plurality of netting rollers 120 and front ends of the plurality of netting rollers 120 . Here, the front end may be a part facing the bow of the vessel 10 based on the longitudinal direction. A portion of the first frame 113a may extend along the longitudinal direction and may be bent upward at the front end of the portion. In addition, a portion extending in the longitudinal direction of the first frame 113a may be penetrated in the vertical direction so as to be disposed on both sides of the plurality of net rollers 120 in the width direction. In addition, an upwardly bent portion of the first frame 113a may be penetrated in the longitudinal direction so that the fishing net 12 passes therethrough. For example, the first frame may be provided as a frame having an 'L' shape through which the inside is penetrated.

The second frame 113b extends obliquely upward along the longitudinal direction from the rear end of the first frame 113a and may be disposed to surround the rear end of the plurality of netting rollers 120 . That is, the second frame 113b may be inclined in the longitudinal direction based on the vertical direction. Here, the second frame 113b may be formed by penetrating the inside in the longitudinal direction so that the fishing net 12 passes therethrough. For example, the second frame 113b may be provided as a frame having an 'n' shape.

Also, the second frame 113b may include a bearing (not shown) at a portion coupled to the first frame 113a. Accordingly, when the fishing net 12 is wound by the plurality of netting rollers 120, the second frame 113b may contact and rotate with the fishing net 12. Therefore, when the fishing net 12 is wound, it is possible to suppress or prevent the fishing net 12 from contacting the second frame 113b and being damaged by friction.

The third frame 113c may be a pillar extending vertically from the rear end of the first frame 113a. Here, the third frame 113c may be located at a front end of the position of the second frame 113b based on the longitudinal direction.

The fourth frame 113d may be connected to an upper portion of the second frame 113b and an upper portion of the third frame 113c, respectively. The fourth frame 113d may fix and support the second frame 113b to the third frame 113c. Accordingly, through the fourth frame 113d, it is possible to suppress or prevent the inclined second frame 113b from drooping downward due to its own weight.

The fifth frame 113e may be formed obliquely crossing the inside of the second frame 113b. More specifically, the fifth frame 113e may be formed to be inclined upward with respect to the width and length directions, and may be disposed obliquely crossing the inside of the second frame 113b. That is, the lower part of the fifth frame 113e may be fixedly coupled to the lower part of the second frame 113b, and the upper part of the fifth frame 113e may be fixedly coupled to the upper part of the second frame 113b. Accordingly, a space gradually narrowing downward is generated between the fifth frame 113e and the second frame 113b, and a portion where the lower portion of the fifth frame 113e and the lower portion of the second frame 113b are connected. The air net 12 can be collected. Accordingly, the fishing net 12 may be guided to a space in which the width between the fifth frame 113e and the second frame 113b is narrowed. Therefore, the fifth frame 113e guides the fishing net so that the fishing net 12 is not twisted with each other in the process of winding the fishing net 12 .

The plurality of netting rollers 120 are rotatably coupled to the main body 110 and may wind the casted fishing net 12 . Among the plurality of netting rollers 120, some of the netting rollers 120 are arranged in a row on the upper part of the side surface of the body part 111, and some of the netting rollers 120 are in a row on the lower part of the side surface of the body part 111. can be placed as In the following, among the plurality of netting rollers 120, the netting rollers 120 arranged in a row on the relatively upper side are referred to as first netting rollers 120a, and the netting rollers 120 arranged in a row on the relatively lower side are It is called two netting rollers (120b). For example, the number of first leveling rollers 120a may be provided in three, and the number of second leveling rollers 120b may be provided in two.

Meanwhile, among the first netting rollers 120a, the first netting rollers 120a disposed in the middle may be disposed at a relatively higher position than the first netting rollers 120a disposed at both ends. Accordingly, the length formed by the first netting rollers 120a in the longitudinal direction can be relatively shorter than when the first netting rollers 120a are arranged at the same height, and a plurality of netting rollers 120 are formed. The overall volume may be reduced. Thus, when the plurality of netting rollers 120 rotate by the support 130, collision with surrounding structures can be suppressed.

In addition, the plurality of netting rollers 120 may include a rotating body 121 , a connecting shaft 122 and a rotating motor 123 . The rotating body 121 is formed in a cylindrical shape extending in the width direction, and a fishing net may be wound on the outer circumferential surface. Rotating body 121 may be equipped with separation prevention plate (121a) having a larger diameter than the diameter of the rotating body 121 at both ends. Accordingly, it is possible to prevent the fishing net 12 wound on the rotating body 121 from being blocked by the release prevention plate 121a and being separated from both ends of the rotating body 121 .

In addition, the rotating body 121 may have a friction ring (not shown) on an outer circumferential surface so as to increase adhesion with the fishing net 12 . For example, the friction ring may be made of rubber. Accordingly, when the fishing net 12 is wound around the rotating body 121, the friction ring (not shown) increases the frictional force between the fishing net 12 and the rotating body 121, so that the fishing net 12 is rotated by the rotating body 121. It is possible to suppress or prevent slipping (that is, idling) on the outer circumferential surface of the.

The connection shaft 122 is coupled to the body portion 111 to be relatively rotatable, one end coupled to the rotating body 121, and the other end coupled to the rotary motor 123. The connecting shaft 122 may receive rotation driving force from the rotation motor 123 to rotate the rotation body 121 .

The rotation motor 123 is installed on the body portion 111 and may be connected to the connecting shaft 122 . The rotation motor 123 may generate a rotational driving force capable of rotating the rotation body 121 .

The plurality of net rollers 120 may be disposed at a first position or at a second position by driving a support 130 to be described later. That is, the plurality of netting rollers 120 may be arranged in parallel with the longitudinal direction in the first position or in parallel with the width direction in the second position. A description related to this will be described in more detail while describing the support 130 below.

5 is an exploded perspective view showing the structure of the support.

The structure of the support 130 according to an embodiment of the present invention will be described with reference to FIGS. 3 to 5 . The support 130 may arrange the plurality of netting rollers 120 at a first position or at a second position. Here, the first position may include all positions where the plurality of netting rollers 120 are disposed on the vessel 10 (ie, within the outermost rim of the vessel 10), and in the following, the first position is the length A case of a position disposed along a direction will be described as an example. Here, the first position may be a state in which operation is not performed with the netting roller 120 .

In addition, the second position may include all positions where at least some of the plurality of netting rollers 120 are disposed outside the vessel 10 (ie, outside the outermost rim of the vessel 10). A case where position 2 is a position disposed along the width direction among directions crossing the length direction will be described as an example. Here, the second position may be a state of operation with the netting roller 120 . In addition, in the following, a state in which the plurality of net rollers 120 are in the first position is referred to as a stored state, and a state in which the plurality of net rollers 120 are in the second position is referred to as an unfolded state.

The support 130 may include a lower body 131, an upper body 132 and an actuator 134. In addition to this, the support 130 may further include a plurality of rotating balls 133 and stoppers 135 .

The lower body 131 may be fixedly installed on the deck 11 of the ship 10. A part of the lower body 131 may extend in the longitudinal direction and another part may extend in the vertical direction. For example, the lower body 131 may be provided in a shape in which a cylinder extending in the longitudinal direction and a cylinder extending in the vertical direction are coupled to each other. Here, both the cylindrical portion extending in the longitudinal direction and the cylindrical portion extending in the vertical direction may be formed by penetrating the inside, and the penetrating interior may communicate with each other. Accordingly, a second gear 134b to be described later is disposed inside the cylinder extending in the longitudinal direction of the lower body 131, and a first gear to be described later inside the cylinder extending in the vertical direction of the lower body 131 ( The spur gear part of 134a) can be arranged. In addition, the first gear (134a) and the second gear (134b) may be engaged with each other in a portion of the lower body 131 through which the inside is communicated.

The upper body 132 may have a lower portion rotatably connected to the lower body 131 and an upper portion fixed to a side surface of the body portion 111 . A portion of the upper body 132 extends in the vertical direction, and a portion may extend in the width direction from an end portion extending in the vertical direction. Here, the upper body 132 may be provided with a fixing body 132a at a portion extending in the width direction and inserted into the insertion hole 112 of the body portion 111 . As described above, the position where the fixture 132a is inserted into the insertion hole 112 may be the same as the height between the first net rollers 120a and the second net rollers 120b in the vertical direction. there is.

The plurality of rotating balls 133 may reduce friction between the upper body 132 and the lower body 131 . The plurality of rotating balls 133 may be rotatably installed on at least one of the lower body 131 and the upper body 132 . In the following, a case in which the plurality of rotary balls 133 are spaced apart from each other along the circumferential direction on the lower surface of the upper body 132 and rotatably inserted into the upper body 132 will be described as an example. At this time, a plurality of grooves (not shown) recessed inward may be formed on the lower surface of the upper body 132 so that the plurality of rotation balls 133 are inserted. Here, a predetermined gap may be formed between the rotating ball 133 and the groove. Thus, the rotary ball 133 may rotate in a groove (not shown). For example, the groove of the upper body 132 and the plurality of rotating balls 133 may be provided in a ball caster structure.

In addition, a lubricant may be filled in the predetermined gap described above. That is, a lubricant may be coated on the outer surface of the rotating ball 133 and the lower surface of the upper body 132 forming the groove. Thus, friction between the rotary ball 133 and the lower surface of the upper body 132 can be reduced, and the rotary ball 133 can rotate smoothly. Here, the lubricant may be a material that reduces friction including grease.

The actuator 134 may be partially installed inside the lower body 131 and partially installed inside the upper body 132 . The actuator 134 may include a first gear 134a, a second gear 134b, and a motor 134c.

A part of the first gear 134a may be formed as a shaft extending in the vertical direction, and a part may be formed as a spur gear coupled to a lower portion of the shaft. The shaft portion of the first gear 134a may have an upper portion fixed to the upper body 132 and a lower portion rotatably coupled to the deck 11 of the ship 10. In addition, the spur gear portion of the first gear 134a may be formed to mesh with the second gear 134b.

The second gear (134b) may be disposed inside the lower body (131). The second gear 134b extends in the longitudinal direction and may have gear teeth provided in a spiral shape on an outer circumferential surface. For example, the second gear 134b may be formed as a worm gear extending in the longitudinal direction. Here, the gear teeth of the second gear 134b may mesh with the gear teeth of the spur gear portion of the first gear 134a. Accordingly, since the first gear 134a is rotated through the second gear 134b provided as a worm gear, a relatively large reduction ratio can be obtained and the first gear 134a can be rotated with a relatively small force. Thus, it is possible to more effectively rotate the main body 110 and the plurality of net rollers 120 connected to the upper body 132 with less force.

The motor 134c may provide rotational force to the second gear 134b. The motor 134c may be disposed in the lower body 131 and coupled to an end of the second gear 134b. Accordingly, the motor 134c may transmit rotational power to the first gear 134a by rotating the second gear 134b. Accordingly, the upper body 132 fixed to the first gear 134a rotates counterclockwise, and the plurality of net rollers 120 and the main body 110 are moved from the longitudinal direction to the width direction, or from the width direction to the longitudinal direction. can be rotated to That is, the arrangement state of the plurality of netting rollers 120 can be switched to an arrangement composition desired by the operator. Therefore, when not in operation, a plurality of netting rollers 120 are housed in the ship 10, and it is possible to suppress or prevent a collision between the external structure and the plurality of netting rollers 120.

The stopper 135 is coupled to the outer circumferential surface of the first gear 134a or the second gear 134b, and limits the rotation angle range of the upper body 132 so that the upper body 132 rotates only in a preset angular range. can In the following, a case in which the stopper 135 is provided as a pair and formed to be coupled to the outer circumferential surface of the first gear 134a will be described as an example. The pair of stoppers 135 may be coupled to gear teeth of the spur gear of the first gear 134a. For example, the stopper 135 may be provided as a block with one surface recessed in a shape corresponding to a screw thread so that it can be fitted into a gear tooth.

In addition, the pair of stoppers 135 may be spaced apart from each other at a predetermined angle along the circumference of the first gear 134a and coupled to the gear teeth. At this time, the angle at which the pair of stoppers 135 are spaced apart along the circumference of the first gear 134a may be the same as the angle between the first position and the second position. That is, it may be the same as the angle between the longitudinal direction and the width direction (eg, an angle between 90° and 120°). Accordingly, when the first gear 134a rotates through the second gear 134b, the stopper 135 and the second gear 134b contact each other, and the rotation of the first gear 134a may be stopped. Therefore, through the stopper 135, the first gear 134a and the upper body 132 can be rotated only within a preset angular range, and the plurality of net rollers 120 are rotated within a preset angular range without a separate control system. can be rotated in

Referring to FIGS. 6 and 7 , the cover part 140 may cover a gap between the plurality of net rollers 120 and the main body 110 . More specifically, the cover part 140 may cover the connection shaft 122 connecting the rotating body 121 and the body part 111 from the upper side. Here, the cover part 140 may be fixed and installed to the body part 140 by a coupling structure such as, for example, an anchor bolt. That is, the cover part 140 is fixedly installed to the body part 111 and can cover the connection shaft 122 regardless of the arrangement state of the plurality of netting rollers 120 .

On the other hand, the cover part 140 may selectively cover the connection shaft 122 according to the arrangement of the plurality of netting rollers 120 . That is, the cover part 140 may cover the connection shaft 122 only when the plurality of netting rollers 120 are in the second position. To this end, the cover part 140 may include a cover plate 141 and a wire 142 . In addition, the cover unit 140 may further include an auxiliary cover plate 143.

The cover plate 141 may be installed on top of the body portion 111 . The cover plate 141 extends in the longitudinal direction and may have an area capable of covering upper portions of the plurality of connecting shafts 122 . For example, the cover plate 141 may have the same length as the length of the body portion 111 in the longitudinal direction, and may have the same width as the interval between the rotating body 121 and the body portion 111 . The cover plate 141 may be fixed to the upper portion of the body portion 111 or rotatably coupled to the upper portion of the body portion 111 . In the following, a case in which the cover plate 141 is rotatably coupled to the body portion 111 will be described as an example. To this end, the cover plate 141 includes a first hinge 141a and may be rotatably coupled to the body 111 through the first hinge 141a.

One end of the wire 142 may be connected to the cover plate 141 and the other end may be connected to the lower body 131 . More specifically, one end of the wire 142 is coupled to the center of the longitudinal length of the cover plate 141, the other end of the wire 142 may be coupled to the rear end of the lower body (131). Here, the wire 142 may be provided with a length of L1. On the other hand, as shown in Figure 6, when the plurality of net rollers 120 are disposed along the longitudinal direction, the length between the center of the longitudinal length of the cover plate 141 and the rear end of the lower body 131 is L1 can be formed as Thus, tension is generated in the wire 142, and the cover plate 141 can be pulled upward so that the cover plate 141 is disposed along the vertical direction (ie, folded).

On the other hand, as shown in FIG. 7, when the plurality of netting rollers 120 are arranged along the width direction by the rotation of the support 130, the center of the longitudinal length of the cover plate 141 and the lower body ( 131) may be formed as L2 shorter than L1. Thus, the tension generated in the wire 142 is released, the cover plate 141 rotates downward by its own weight, and can be disposed (ie, unfolded) along the width direction. Thus, the cover plate 141 can cover the connecting shaft 122 from the upper side of the connecting shaft 122, and when the fishing net 12 is wound, foreign substances scattered from the fishing net 12 flow into the connecting shaft 122. can block it

The auxiliary cover plate 143 is formed in a plate shape extending in the vertical direction and may be rotatably coupled to the cover plate 141 . To this end, the auxiliary cover plate 143 may be provided with a second hinge (143a). The auxiliary cover plate 143 is provided in plurality, and may shield a space between the connecting shafts 122 supporting the first two-net rollers 120a. More specifically, the auxiliary cover plate 143 rotates at the end of the cover plate 141 when the cover plate 141 rotates and is spread upward of the connecting shaft 122, and the connection between the plurality of connecting shafts 122 can be spread out in space. Accordingly, since the auxiliary cover plate 143 shields the gap between the rotating bodies 121, it is possible to block the gap between the rotating body 121 and the connecting shaft 122, and between the plurality of rotating bodies 121. The auxiliary cover plate 143 may block the fishing net 12 protruding through the gap and being wound around the connecting shaft 122. Therefore, at the same time as the cover plate 141 is unfolded, the auxiliary cover plate 143 is also spread in the space between the plurality of connecting shafts 122, and the fishing net 12 is suppressed or prevented from coming over the connecting shaft 122. can

The control unit (not shown) may selectively control the arrangement of the plurality of netting rollers 120 . That is, the controller may stop the plurality of net rollers 120 rotating in the circumferential direction at a predetermined position desired by the user. Here, the circumferential direction may be a circumferential direction of a circle having a vertical direction as a central axis. To this end, the controller may include a detector, a judge, and a controller.

The detector is coupled to the upper body 132 and can detect an angle at which the upper body 132 rotates. For example, the sensor may be provided as an angular rotation sensor.

The determiner is connected to the sensor, and the upper body 132 can compare the rotation angle with a preset angle. The determiner may transmit a rotation stop signal to the controller when the rotation angle of the upper body 132 matches the preset angle.

The controller is connected to the determiner and the motor 134c, and can stop driving of the motor 134c when receiving a stop signal from the determiner. Thus, through the control unit, the user can automatically rotate the plurality of netting rollers 120 and stop them at preset positions.

In this way, all of the plurality of net rollers can be accommodated on a ship (ie, inside a ship). Thus, it is possible to suppress or prevent a plurality of netting rollers from colliding with an external structure. In addition, by rotating a plurality of netting rollers, the arrangement of the plurality of netting rollers can be formed at various angles. Thus, the cast driftnet can be effectively wound. In addition, it is possible to suppress or prevent the drift net from being caught in the gap when winding the drift net by covering the gap between the plurality of netting rollers and the main body.
