Description

  The present invention relates to a structure of a tugboat that stores a kite that is used as a fish when fishing for kites.

  There is a fishing method called “friend fishing” in carp fishing. In friend fishing, a living carp is used as a bird. A fisherman attaches a fishing hook to this rod and allows it to enter the target rod territory, thereby inviting an attack on the rod. Therefore, in fishing with friends, a salmon with a physical strength is selected as a bird, and the angler carefully observes the rod that becomes a bird at all times, and if it determines that the strength of the rod has declined, it immediately replaces the rod that becomes a bird. Therefore, it is necessary for the angler to always prepare a plurality of fishing rods for actual fishing.

  In conventional kite fishing, a fisherman uses a boat-shaped container called a “boat” to store kites for fishing. The angler always carries this dredger during actual fishing (for example, Patent Literature 1 to Patent Literature 4), and keeps the rod used as a bird. FIG. 10 is a perspective view of a conventional general barge.

  As shown in the figure, the tugboat 1 includes a main body 2 formed in a ship shape and a rope 3 connected to the main body 2. The rope 3 is provided with hooks 4 to 6, and a fisherman can moor the rowboat 1 by hooking the hooks 4 to 6 on a body or a fixed object at a fishing spot. The tugboat 1 is used by floating on the surface of the water, and has a storage chamber for storing the kite inside. The main body 2 includes a water supply port and a water discharge port 8 which are not shown in the figure. Therefore, water constantly enters and exits the storage chamber. Moreover, since the main body 2 is formed in a ship shape, the angler can easily move the fishing ground while the tugboat 1 is placed in the water.

  By the way, in carp fishing, anglers often move around the water. In that case, fresh water must always be supplied to the containment chamber of the barge 1. By providing a large water supply port in front of the main body 2 and a large water discharge port in the rear, water flows into the storage chamber vigorously and is discharged. However, in this case, there is a problem that the water flow in the accommodation chamber becomes too fast, and the dredging is weakened.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a kite fishing barge in which fresh water is always supplied to a rod accommodated in a storage chamber at an appropriate flow rate.

  (1) In order to achieve the above-mentioned object, the kite fishing tugboat according to the present invention has a tugboat main body formed in a boat shape and having a housing chamber for housing the kite inside. A water supply hole communicating with the accommodation chamber is provided on the front of the bow of the tugboat body. Moreover, the drainage hole connected to the said storage chamber is provided in the both left and right side surfaces of the said boat boat main body. Furthermore, a lift adjustment hole that communicates with the accommodation chamber and adjusts the lift acting on the main body of the tugboat is provided at a boundary portion between the bottom of the main boat body and the front of the bow.

  This fishing boat is floated on the river surface while being anchored by the angler during actual fishing, and moves along the river with the angler. At this time, water hits the front of the bow from the front of the tugboat main body, and moves backward along the port side and starboard side of the tugboat main body and the ship bottom. That is, the dynamic pressure acts on the front of the bow of the tugboat main body, and the static pressure acting on the port side and starboard side of the tugboat main body and the ship bottom decreases.

  Since the water supply hole is provided in the front of the bow of the tugboat body, the dynamic pressure is suppressed at the same time that water enters the storage chamber through the water supply hole. That is, the lift acting on the main body of the tugboat is suppressed. For this reason, the bow of the main body of a tugboat does not go up too much, and water can be smoothly supplied into the said storage chamber from the said water supply hole. Further, since the static pressure is reduced, the water in the storage chamber is smoothly discharged from the drain hole to the outside. Therefore, the water smoothly guided from the water supply hole to the accommodation chamber is smoothly discharged to the outside from the drain hole. However, since the drainage hole is provided on the port side and starboard side of the tugboat body, water does not abruptly spout outside from the storage chamber.

  Further, the lift force acting on the main body of the tugboat is adjusted by providing the lift adjustment hole at the boundary between the bottom of the tugboat body and the front of the bow. Specifically, the lift can be adjusted in the following manner.

  In actual fishing, since this fishing boat is usually floated in running water, the water always hits the front of the bow of the boat body as described above. Therefore, the bow of the tugboat body moves up and down with respect to the river surface. When the ship bottom of the tugboat body is arranged substantially parallel to the flow of water, the water flows so as to go around from the front of the bow to the ship bottom. As a result, the static pressure at the bottom of the ship is lowered, and water in the accommodation chamber is appropriately discharged from the lift adjustment hole.

  When the bow of the tugboat body moves upward with respect to the river surface, the water hits the bottom of the tugboat body at a certain angle, and dynamic pressure is generated at the bottom of the ship. On the other hand, as described above, since the lift adjustment hole is provided at the boundary between the bottom of the tugboat body and the front of the bow, when the bow of the charter body moves upward with respect to the river surface, the lift adjustment hole is It faces the water at a predetermined angle. For this reason, the water enters the storage chamber through the lift adjustment hole, and the dynamic pressure is suppressed. Therefore, the bow of the fishing boat moored by the angler does not rise extremely, and as a result, water reliably enters the accommodation chamber from the water supply hole and the lift adjustment hole.

  In addition, when the bow of the main body of the tugboat moves downward with respect to the river surface, the water flows so as to greatly wrap around from the front of the bow to the bottom of the ship. As a result, the static pressure at the bottom of the ship is greatly reduced, and the main body of the tugboat tends to receive a force in the direction of sinking in water. However, when the static pressure at the bottom of the ship is lowered, the water in the storage chamber is discharged from the lift adjustment hole, thereby suppressing the force in the direction of sinking into the water.

  Thus, by providing the lift adjustment hole, the lift acting on the main body of the tugboat is adjusted even when the main body of the tugboat moves up and down on the river surface during actual fishing. Therefore, the bow of the fishing boat moored by the angler does not rise extremely, and as a result, water reliably enters the storage chamber from the water supply hole or the like.

  (2) When the distance from the bow top end to the lower edge of the main body of the tugboat is H, the water supply hole is preferably arranged in a region of 0.5H to 0.95H downward from the bow top end. . That is, the water supply hole is provided below (in the ship bottom side) below the center of the bow front. Thus, even when the water flow is fast and the towboat body moves up and down violently on the river surface during actual fishing, the water supply hole is always placed in the water. Therefore, there is an advantage that fresh water is always supplied into the accommodation chamber.

  (3) The water supply hole may be constituted by an elongated through hole extending in a vertical direction on the front surface of the bow. By forming the water supply hole with such an elongated through-hole, even if the bow of the tugboat body moves up and down while being moored by a fisherman, the dynamic pressure acting on the tugboat body, that is, the lift force is applied. There is an advantage that it can be effectively suppressed.

  (4) The drain hole may be constituted by an elongated through hole extending in the front-rear direction of the left and right side surfaces. By forming the water supply hole by such an elongated through hole, there is an advantage that the water in the accommodation chamber is more smoothly discharged when the main body of the tugboat advances relative to the water.

  (5) It is preferable that the lift adjustment hole is constituted by an elongated through hole extending in the front-rear direction so as to be bridged between the front face of the bow and the bottom of the ship. Thereby, the magnitude of the lift acting on the main body of the tugboat during actual fishing is adjusted only by adjusting the position of the lift adjustment hole in the front-rear direction. Therefore, the design for stabilizing the main body of the tugboat on the river surface is easy.

  According to the present invention, since the dynamic pressure acting on the main body of the tugboat is suppressed, water is stably introduced into the storage chamber and the rapid drainage from the storage chamber is suppressed. It is introduced and drained at a moderate flow rate. As a result, fresh water is always supplied to the bag in the storage chamber at an appropriate flow rate, so that the strength of the bag is maintained for a long time.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  1 and 2 are perspective views of a fishing boat for fishing according to one embodiment of the present invention. FIGS. 3 to 8 are a left side view, a front view, a right side view, a plan view, a rear view, and a bottom view, respectively, of this carp fishing boat.

  This carp fishing boat 10 is used for preserving a carp used as a fish during carp fishing. The carp fishing boat 10 is moored by the angler's body during actual fishing and floated on the river surface. The fishing boat 10 is provided with a boat main body 11 and a mooring rope (not shown). One end of the mooring rope is connected to a rope anchor 12 provided at the bow of the tugboat main body 11, and the other end is connected to, for example, a fisherman's waist.

  The tugboat main body 11 has a boat-like appearance and is made of, for example, a resin such as acrylonitrile butadiene styrene copolymer (ABS) or polypropylene (PP). In this embodiment, the rowboat main body 11 has the lower main body 35 and the upper main body 36, and these are fitted in the up-down direction. The position where both are fitted is indicated by a parting line N1 in FIG.

  The inside of the tugboat main body 11 is a cavity, and the accommodation chamber for accommodating the salmon is constituted by this cavity. Further, an opening (not shown) is provided on the upper surface 13 of the tugboat main body 11, and a lid 14 for opening and closing the opening is provided. The lid 14 is attached to the tugboat main body 11 via a hinge 15. Accordingly, in FIG. 1, the lid 14 is rotatable between a posture in which the lid 14 falls down and closes the opening, and a posture in which the lid 14 stands up with respect to the upper surface 13 and opens the opening. It has become.

  When the lid 14 is in the standing posture, the opening that is closed by the lid 14 is exposed. This opening communicates with the accommodation chamber. When the lid 14 is opened, the angler can easily put and remove the rod into the accommodation chamber. Further, the lid 14 includes a lock mechanism 17. The locking mechanism 17 maintains the lying posture when the lid 14 is in a lying posture, that is, when the lid 14 closes the opening, and the lid 14 opens and closes when the angler does not intend. Is preventing. The lock mechanism 17 includes a knob 18, and the angler can open and close the lid 14 by operating the knob 18.

  Note that the lid 14 is provided with a door 16 in the fishing boat 10 for carp fishing according to the present embodiment. The door 16 is a so-called double door, and opens and closes inside the tugboat main body 11. Therefore, the angler can easily enter the caught rod through the door 16 without opening the lid 14.

  As described above, since the tugboat body 11 is formed in a boat shape, in this specification, the front surface 28 of the tugboat body 11 is a “front surface 28” and the right side surface 29 in the traveling direction of the tugboat body 11 (see FIG. 5). ) Is referred to as “starboard side surface 29”, the left side surface 30 in the traveling direction of the rowboat main body 11 is referred to as “portside surface 30”, and the bottom surface 31 (see FIG. 8) of the rowboat main body 11 is referred to as “boat bottom 31”. Further, the positions on the bow front surface 28, starboard side surface 29, and port side surface 30 are determined with reference to the parting line N1 and a virtual vertical line N2 passing through the bow top end 32 of the boat body 11 as shown in FIG. . The “top end 32” is an intersection of the parting line N1 and the outer edge of the main body 11 of the tugboat.

  The tugboat main body 11 is provided with water supply holes 19 to 21, drainage holes 22 to 24, and lift adjustment holes 25 to 27 (see FIG. 8), which will be described in detail later. These communicate with the interior of the tugboat main body 11. Therefore, when this tugboat 10 is floated on the river surface, water enters the inside of the tugboat main body 11, that is, the accommodation chamber. The buoyancy of the tugboat main body 11 is set so that the tugboat 10 for dredging fishing does not sink even when water enters this accommodation room. Various known means are adopted to adjust the buoyancy of the tugboat main body 11. In this embodiment, as shown in FIG. 3, the position of the water surface when the carp fishing tugboat 10 is floated on the water surface without flow. Is set to coincide with the waterline K1.

  However, since the fishing boat 10 is floated on the river surface when actually used, the water hits the bow front surface 28 at a constant speed. Further, since the mooring rope connected to the rope anchor 12 is connected to the waist of the fisherman, the fishing boat 10 for fishing is relatively pulled in the direction of the angle θ in actual fishing. This angle θ is normally set in a range of 0 ° (degree) <θ ≦ 45 ° with respect to the horizontal line (parting line N1). For this reason, the position of the water surface at the time of use of the carp fishing boat 10 coincides with the waterline K2.

  As shown in FIGS. 3 to 5, the water supply holes 19 to 21 are provided in the bow front surface 28. Each water supply hole 19-21 is arrange | positioned at the said bow front surface 28 symmetrically, and is located below the said waterline K2. Each of the water supply holes 19 to 21 is formed of an elongated through hole, and extends in the vertical direction along the bow front surface 28. The upper ends of the water supply holes 19 to 21 are respectively at heights h1, h2, and h3 with respect to the parting line N1. Specifically, when the height from the bow top 32 to the ship bottom (lower edge) with respect to the parting line N1 is H (see FIG. 3), the height h1 = 0.50H and the height h2 = 0.53H, height h3 = 0.60H. Moreover, the lower end of each water supply hole 19-21 is in the position of height h4 on the basis of the said parting line N1, respectively. In the present embodiment, the height h4 is set to 0.8H. Of course, the heights h1 to h4 can be variously modified, but the water supply holes 19 to 21 are arranged in a region of 0.5H to 0.95H with the parting line N1 as a reference. It only has to be.

As shown in FIGS. 3 to 5, the drain holes 22 to 24 are provided on the starboard side surface 29 and the port side surface 30. Each drain hole 22-24 is located below the said waterline K2, and is arrange | positioned at the said port side 30 and the starboard side 29 left-right symmetrically. Each drainage hole 22-24 consists of an elongate through-hole, and is extended in the front-back direction along the port side surface 30 and the starboard side surface 29. As shown in FIG. As shown in FIG. 3, each of the drain holes 22 to 24 is located at heights h5, h6, and h7 with respect to the parting line N1. Specifically, with reference to the parting line N1, the height h5 = 0.65H, the height h6 = 0.45H, and the height h7 = 0.27H. But about these heights h5-h7, as long as each drain hole 22-24 is located below the said waterline K2, it can be suitably set in 0.20H thru | or 0.90H. In addition, the drain holes 22 to 24 are disposed at substantially the center of the port side surface 30 and starboard side surface 29 of the boat main body 11. Specifically, when the height from the bow top 32 to the stern with reference to the virtual vertical line N2 is L (see FIG. 3), each drain hole 22 is within a region of 0.35L to 0.70L. -24 should just be provided.

  Further, as shown in FIG. 8, the lift adjustment holes 25 to 27 are provided in a boundary portion 33 between the bow front surface 28 and the ship bottom 31. The lift adjustment hole 25 is provided at the center of the ship bottom 31, and the lift adjustment holes 26 and 27 are arranged symmetrically about the lift adjustment hole 25. Each lift adjustment hole 25-27 consists of an elongate through-hole, and is extended along the front-back direction of the ship bottom 31 so that it may span between the said bow front surface 28 and the ship bottom 31. As shown in FIG.

  This fishing boat 10 is used in the following manner in actual fishing.

  The angler ties the mooring rope to his body and floats the fishing boat 10 on the river surface. As a result, the fishing boat 10 is anchored by a fisherman and floats on the river surface. Water from the river hits the front surface 28 from the front of the main boat body 11, and moves backward along the port side 30, starboard side 29, and ship bottom 31. Move to. That is, dynamic pressure acts on the bow front surface 28 of the tugboat body 11, and static pressure acting on the port side surface 30, starboard side surface 29, and ship bottom 31 decreases. The boundary line between the fishing boat 10 at this time and the water surface, that is, the draft line K2 is in the state shown in FIG.

  Since the water supply holes 19 to 21 are provided in the bow front surface 28 of the tugboat main body 11, water enters the storage chamber of the boat main body 11 from each water supply hole 19 to 21, and the dynamic pressure acting on the bow front surface 28 is suppressed. It is done. That is, the lift force acting on the main boat body 11 is suppressed. For this reason, the bow of the tugboat main body 11 does not go up too much, and water can be smoothly supplied into the said storage chamber from the said water supply holes 19-21. Moreover, since the static pressure which acts on the port side surface 30, starboard side surface 29, and ship bottom 31 falls, the water in the said storage chamber is smoothly discharged | emitted from the said drain holes 22-24 outside. Therefore, the water smoothly guided from the water supply holes 19 to 21 to the accommodation chamber is smoothly discharged from the drain holes 22 to 24 to the outside. However, since each drainage hole 22-24 is provided in the port side 30 and starboard side 29 of the dredger main body 11, water does not spout suddenly outside from the said storage chamber.

  And since the lift adjustment holes 25-27 are provided in the boundary part 33 of the ship bottom 31 of the tugboat main body 11 and the bow front surface 28, the lift which acts on the tugboat main body 11 is adjusted in the following way. FIG. 9 is a diagram schematically illustrating how water flows near the bottom 31 of the tugboat body 11.

  The flow velocity of the river is not always constant, and the velocity of water that collides with the bow front surface 28 of the tugboat main body 11 changes constantly. Moreover, since the angler usually moves along the river during actual fishing, the angle θ (see FIG. 3) also changes. For this reason, the attitude of the tugboat main body 11 with respect to the river surface always changes, and the bow part of the tugboat main body 11 always moves up and down with respect to the river surface. As shown in FIG. 9A, when the bottom 31 of the tugboat main body 11 is arranged substantially parallel to the flow of water, the water 38 flows from the bow front surface 28 to the ship bottom 31. . Thereby, the static pressure which acts on the ship bottom 31 falls, and the water 39 in the storage chamber 37 of the tugboat main body 11 is discharged | emitted moderately from the lift adjustment holes 25-27.

  As shown in FIG. 4B, when the bow of the tugboat body 11 moves upward with respect to the river surface, the water 38 hits the bottom 31 of the tugboat body 11 at a certain angle. As a result, dynamic pressure is generated at the ship bottom 31. On the other hand, since the lift adjustment holes 25 to 27 are provided in the boundary portion 33 between the ship bottom 31 and the bow front surface 28, when the bow of the tugboat body 11 moves upward with respect to the river surface, the lift adjustment holes 25 to 27 are formed as described above. It faces the water 38 at a predetermined angle. Therefore, the water 38 enters the storage chamber 37 from the lift adjustment holes 25 to 27, and the dynamic pressure is suppressed. Accordingly, the bow of the fishing boat 10 is not excessively raised during actual fishing, and as a result, the water 38 surely enters the storage chamber 37.

  As shown in FIG. 5C, when the bow of the tugboat body 11 moves downward with respect to the river surface, the water 38 flows so as to greatly wrap around from the bow front surface 28 to the ship bottom 31 side. Thereby, the static pressure which acts on the ship bottom 31 falls greatly, and the tugboat main body 11 exists in the tendency to receive the force of the direction which sinks in water (downward in the figure). However, when the static pressure acting on the ship bottom 31 is reduced, the water 39 in the storage chamber 37 is discharged from the lift adjustment holes 25 to 27. Thereby, the force which sinks the rowboat main body 11 to a water flow is suppressed. That is, the attitude of the tugboat main body 11 is returned to the attitude shown in FIG.

  As described above, in the fishing boat 10 according to the present embodiment, the dynamic pressure acting on the boat main body 11 is suppressed and water is surely introduced into the storage chamber 37, and the abruptness from the storage chamber 37 is increased. Since drainage is suppressed, water is introduced and drained into the accommodation chamber at an appropriate flow rate. Moreover, by providing the lift adjustment holes 25 to 27, even when the rowboat body 11 moves up and down on the river surface during actual fishing, the posture is stabilized by adjusting the lift acting on the rowboat body 11, Water is reliably supplied to the storage chamber 37 of the tugboat body 11. As a result, fresh water is always supplied to the bag in the storage chamber 37 at an appropriate flow rate, so that the physical strength of the bag is maintained for a long time.

  In particular, in this embodiment, the water supply holes 19 to 21 are 0.5H to 0.95H when the distance from the bow top end 32 of the tugboat main body 11 to the ship bottom 31 is H as shown in FIG. Arranged in the area. In other words, each of the water supply holes 19 to 21 is provided below the center of the bow front surface 28 (on the bottom 31 side). Thereby, even when the river flow is fast and the dredger main body 11 moves up and down violently on the river surface during actual fishing, the water supply holes 19 to 21 are always arranged in the water. . Therefore, there is an advantage that fresh water is always supplied into the storage chamber 37.

  In addition, since the water supply holes 19 to 21 are formed by elongated through holes extending in the vertical direction, the bow portion of the rowboat main body 11 moves up and down while the rowboat 10 is anchored by a fisherman. Moreover, each water supply hole 19-21 is reliably arrange | positioned in water. Therefore, even when the bow portion of the tugboat body 11 moves up and down, the dynamic pressure acting on the tugboat body 11, that is, lift is effectively suppressed.

  Furthermore, since the drain holes 22 to 24 are constituted by elongated through holes extending in the front-rear direction of the port side surface 30 and starboard side surface 29, when the rowboat main body 11 moves forward relative to water, There is an advantage that the water in the storage chamber 37 can be discharged more smoothly.

  In addition, in this embodiment, since the lift adjustment holes 25 to 27 are arranged so as to be bridged between the bow front surface 28 and the ship bottom 31, the lift force when the bow portion of the tugboat body 11 moves up and down. Adjustment effect is high. Further, the degree of lift adjustment effect exerted on the tugboat main body 11 can be adjusted only by adjusting the positions of the lift adjustment holes 25 to 27 in the front-rear direction. Therefore, the design of the dynamic pressure acting on the tugboat main body 11 is easy, and the tugboat main body 11 can be formed so that water can surely enter the storage chamber 37.

  The present invention can be applied to a tugboat used for carp fishing.
