Description

  The present invention is towed by trapping fish, catching fish while catching fish from fishing boats such as purse seine fishery, stationary net fisheries, rod catch fisheries, laying net fisheries, etc. It is about possible ginger.

  In 1994, the United Nations Convention on the Law of the Sea came into force, including the obligation of coastal countries to manage biological resources in the surrounding waters. Under the groundbreaking legislation that led to a global sea constitution, Japan ratified the treaty in 1996 and newly enacted a resource management law concerning the conservation and management of marine biological resources. Laws have been enacted such as the obligation to preserve and manage biological resources in the case of overfishing of fishery resources, the sustainable use of resources in 200 nautical miles of water, etc. The environment surrounding the sea is being drastically reformed, including the establishment of the Basic Law on Fisheries in 2001 and the Basic Law on Oceans in 2007.

  The main fishing boat fishery of fisheries is responsible for 70% of Japan's fishery production, and is an important position in securing a stable supply of fishery products. However, in addition to the deterioration of resources, import expansion, sluggish fish prices, There is a need for drastic structural changes in the fishing industry, such as deterioration.

  In addition, problems such as large-scale catch of small fish by pre-harvest of fisheries resources, excessive equipment, decline in fish prices due to concentrated landing, excessive concentration of fishing boats to specific fishing grounds, destruction of fishing grounds, etc., lead to depletion of fishery resources. Conservation measures and sustainable effective use measures are urgently needed. In addition, in order to use fishery resources more stably and continuously, fish management is performed based on the catch potential (TAC) and catch effort (TAE).

  Under these circumstances, there are cases where fishing grounds were relatively close in conventional stationary net fisheries, etc., in which the sleepers were thrown into the sea, the fishermen jumped into the sea, assembled, towed the fishing nets, and aquaculture (stationary) fishing nets Towing the ginger and providing live feed for one tuna and skipjack fishing. In addition, dedicated fishing boats and live fish carriers with live fish ginger in the boat are used.

  In addition, overseas tuna aquaculture industry towed the purse seine fishery with ginger of a large fishing net, but due to the slow towing speed and returning to the tide, it was sometimes forced to sail for 3 months. For this reason, it is a dangerous method, such as divers diving in the ginger, repairing fishing nets and supplying food.

  In the first place, fishing net ginger is a fishing method that has various problems in towing speed, workability, viability, etc. Since the towing resistance is large, a large towed vessel is required, and there is a lot of time and cost loss, causing pressure on fishery management.

  For example, in Patent Document 1 below, a plurality of vertically long ballast tanks that are divided in the left-right direction on the bottom of the main body and the double wall portions on both sides are provided, and the ballast tanks are individually ballasted. A towed ginger provided with a ballast dispensing device for dispensing is disclosed.

  Patent Document 2 below is an intake for taking in directly from a fishing net, and has a door that can slide up and down on the side of the ginger, and the door is configured to be movable up and down by a winch, There is disclosed a live fish intake for a towed ginger provided with means capable of releasing the avatar floating a fishing net at the top of the door.

Japanese Unexamined Patent Publication No. 04-141035 Japanese Patent Laid-Open No. 04-088934

  However, the above technique has problems including the operation method at the time of ups and downs and the efficiency, workability, and survival of the ups and downs time.

  For example, the seawater ballast pouring / draining system of the ballast tank of Patent Document 1 is provided with a plurality of ballast tanks having different volumes divided in the left-right direction and independent from each other, Has an operation to float and sink evenly, especially in purse seine fisheries, after the net is thrown in, the fishery can escape, or the fishing grounds are changed or repeated for dangerous operations due to wind and wave swells Everything is normal, and you have to repeat ups and downs each time, which is the cause of overwork and increased costs.

  Moreover, the slide opening / closing door of the live fish intake of Patent Document 2 is a mechanism that constitutes a fish passage by fixing a sinker-side avatar to the upper part of the sliding door and sinking it. In addition, since the door area is 50% of the maximum shape with respect to the height of the ginger shape, fish is collected on the catching net side due to insufficient depth of the intake, and inserted into threads or nets, leading to poor survival.

  Furthermore, even in the light operation, the fish collected by the fishing light is stored using fishing nets, tammo, fish pumps, etc., and the survival rate is deteriorated due to threading, pressure, stress, and the like.

  Accordingly, an object of the present invention is to provide a drastic energy saving / cost saving system for fishing boats and fisheries, which has a function of being easily operated and operated by itself.

  The ginger according to claim 1 is a vertically long, ship-shaped towable ginger, a multiple-structure fish tank that floats independently within the main body of the ginger, a float that is located on both sides of the main body of the ginger, and It is characterized by having a bellows type float that can be expanded and contracted by air supply and exhaust, and a net door that can take in fish on the rear surface of the fish tank, which is arranged on the inner bottom plate or on both sides of the fish tank. .

  In addition, the ginger according to claim 2 includes an edge light on the front inner wall surface and both inner wall surfaces of the fish tank, a light guide lamp arranged from the front to the rear in the upper opening of the fish tank, and the vertically long It is characterized by having a light fishing light on the ship-shaped deck.

  According to the ginger according to claim 1 of the present invention, the multiple structure of the fish tank expands the fish tank volume and the intake area, and dramatically improves the work efficiency and the survivability / transport ability in the fishing ground. By increasing the size of the intake port, it is possible to prevent bycatch as an escape port for small fish, and to realize an environmentally-conserved ginger that can escape without human intervention even during the escape process.

  In addition, the bellows type float installed on the bottom plate of the fish tank can perform the floating and sinking operations in the ginger body and the fish tank multiple structure properly and smoothly, making it easy to install the ginger water and fish tank deep water position. Can be. In addition, a bellows type float is installed on the bottom plate of the fish tank, and the bellows type float itself can be used as a safety device (mat) at the time of air supply. It is possible to realize a sacrifice of high value-added function that secures the volume without affecting the product.

  According to the ginger according to claim 2 of the present invention, in addition to the effect of the ginger according to claim 1, the ginger itself has an operation function, and there is a new fishing method that enables unmanned operation without any human intervention. Realize structural reforms to reduce and streamline fishing boats and fisheries, and realize a stable transfer of defined supplementary amounts with ultimate freshness.

  An embodiment according to the present invention will be described with reference to FIGS.

  The ginger in this embodiment has a towable vertical hull shape with B larger than A in FIG. 1 showing the plane of the ginger, and the left and right width of the front portion becomes smaller as it goes forward, and the left and right width of the front end Is very narrow. The left and right widths of the rear part also become smaller as going back, and the rear end is formed flat. A main body bottom plate 12 and a wall portion having a ship side outer plate 13 and a stern outer plate 14 are provided around the main body bottom plate 12, and a vertical wall 15 a bow bulkhead 16 a stern bulkhead 17 having a double wall inside the main body surrounded by these wall portions. A multi-structure fish tank 18 communicating with the outside is formed. In FIG. 2 showing the rear part of the ginger, a fish intake net door 4 is provided on the rear side surface where the ginger body 1 and the fish tank 18 communicate with each other.

Moreover, FIG. 3 which shows sectional drawing of FIG. 1I-II line | wire of a ginger is provided with the float 3 which gave the buoyancy of the ginger's own weight to the double wall part of the main body ginger 1, and is in the position on the low board 22 in a fish tank. It is sectional drawing which shows arrangement | positioning of the bellows type float 2 provided, and arrangement | positioning of the bellows type float side surface or the travel stabilization fin storage space 19 in the both sides of a main body. A towing ginger made of steel with this shape (weight 50t) was towed on a 5t class fishing boat, 3 knots when submerged, and 6 and 5 knots when ascending, based on the design values, You can tow faster.

  In other words, the improvement of the towing speed in the towing ginger is in the completion of the towing gutter shape that can be increased depending on the ability of the towing vessel, and further improvement in the towing speed power such as FRP, waste plastic, high performance resin, etc. It is possible to improve towing speed by using lightweight materials.

  In addition, the material of the ginger in this embodiment is effective in providing light weight and low cost by using waste plastic recycling material (strength three times that of concrete). Since it is important for the construction of an environmental conservation type industry, it is preferable to select materials according to the fishery fish species and circumstances.

  As shown in FIGS. 4 to 5, the ginger floating structure of the present embodiment is formed of an excellent material such as rubber, and expands and contracts with air supply / exhaust, and the bellows type float 2 divided into multiple details includes: It is installed at a position where the ginger body is floated and balanced in a well-balanced manner, and is installed on the fish tank inner bottom plate 22 or the bellows type float side surface or the running stabilization fin storage space 19. The compressed air sent into each of the bellows type floats 2 divided into multiple details can be sent out by placing a compressor in the towed ship or ginger warehouse 21.

  In addition, the ginger according to the present embodiment is provided with the running stabilization fin 6 to prevent meandering and further improve the towing speed force in order to prevent meandering in light-load flooding. In addition, the running stabilization fin 6 suffers from the resistance of water during rotation and sideways operation when fishing at the fishing ground, when berthing at the fish port, or when transferring fish and shellfish, and the operation mobility of the towing ginger body is poor. Therefore, it is a manual storage type.

  The bellows type float 2 has a multi-layer structure consisting of three layers as shown in FIGS. 6 to 8, and the advantage of the bellows type float 2 that is divided into the upper, middle and lower layers in detail is that the power at the time of floating and sinking is gas In addition, since the airfoil type float 2 divided into multiple details can be supplied individually and evenly, the operation is sensitive and can float and sink quickly. At the time of subsidence, seawater flows in from the rear intake network door 4 with exhaust, and the bellows type float 2 accelerates the exhaust speed by pressurizing the seawater itself, and the bellows shape contracts well, so the fish tank The structure secures the volume without affecting the 18 volume.

  In addition, the ginger bellows type float 2 in the fish tank with the low plate 22 installed in the tank is filled with air when lightly loaded, and works on the work platform 23 where the height to the bottom of the ship is 6-7 m. In many cases, the bellows type float 2 itself is an excellent material such as rubber even if it falls into the fish tank 18, so that the safety of work is important.

  As shown in FIG. 9, the buoyancy of the ginger body 1 at the time of subsidence is composed of a ginger-integrated air chamber float 3, and the drowning value is set slightly below the upper part of the intake network door 4, and the ginger This is a ginger-integrated air chamber float 3 installed at a balanced front / rear and left / right position.

  Cross-sectional views or plan views taken along lines II-II shown in FIGS. 10 to 11 are explanatory views showing the arrangement of the light guide lamp 9, the light fish lamp 10, and the edge light 11 in the ginger of this embodiment.

The ginger that combines the light of this embodiment is composed of ultra-bright light-emitting diodes (LEDs), and it also has a light source that excels in ultra-brightness, long life, and energy saving, among which yellow, green, and red with high illuminance This is a light towed ginger that can change color and mix colors depending on the target fish species.

  In addition, the power source of the ginger body 1 using light according to the present embodiment is supplied from a towed ship, arrives at the fishing ground, determines the target fish type, determines the color of the light illumination, and lightly loads the light collecting lamps 10 to 10a. It is lit in a flooded state, and the fish collection effect is further improved by dropping the light source over a wide range from a high position. After confirming the fish and shellfish collected at the bottom left and right of the ginger, the ginger is submerged. At the same time, after turning off the left and right light collection lamps 10 and confirming the collection of fish under the rear light collection lamps 10a, turning off the rear collection lamps 10a and simultaneously turning on the light guide lamps 9 and the edge lights 11, the fish and shellfish enter the ginger fish tank 18. A series of light-guided acquisitions are completed. In addition, in the case of a ginger without a light collecting lamp 10, after confirming that the light boat has collected the fish, the light collecting lamp 9 and the edge light 11 are turned on when the light collecting lamp 9 and the edge light 11 are turned on. With the edge light 11 from the front of the sea, the seafood is guided into the ginger in the same manner as the light collecting light installation type.

  The ginger light of this embodiment is composed of ultra-high brightness light emitting diodes, especially the yellow LED is 1.6 W, 500 lx, and has a long life of 30,000 hours to 50,000 hours. The color LED is the same 1.6W, 225 lx, 15,000 hours, and the illuminance and time are less than half, and it is not suitable for fish collection / guide lights, but the green LED 420 lx and the red LED 280 lx are illuminance power However, the mixed color of the three-color LED improves the effect as the guide light 9 and the fish collection light 10, and the edge light 11 also uses the same mixed color to improve the fish collection performance. In order to improve the stress and survivability of seafood, the blue LED has a low illuminance of 120 lx, making it difficult to adapt to fish collection / guidance, etc. When illuminance LED, etc. is effective bactericidal action eliminates the stress, the edge light 11 of the present embodiment adds a blue LED functionality, good in edge light 180 × 300 type low cost type. In both cases, waterproofing is applied.

  As a result, the seafood guided and collected by the light ginger according to the present embodiment confirms an amount close to 100% as much as the survival rate with respect to the ginger volume, and ends the operation. repeat. In this case, although the ginger itself is sinking, it is preferable to have a structure in which the height of the tower of the light fishing lamp 10 is arbitrarily changed. At the time of re-operation, the division sheet 8 is provided and held in order to prevent escape of fish and shellfish already collected. The zoning sheet 8 is preferable if it can prevent the threading and insertion of the fish body, even in a fishing net with fine meshes, such as holes and cuts that can be tided in vinyl form. A transparent vinyl sheet is more effective.

  In addition, the division sheet 8 has a sheet wound around a roll-shaped pipe 24 in advance as shown in FIGS. 12 to 13, and is provided with a guide rail 25 for dropping as shown in FIGS. The roll pipe 24 after dropping and depositing is free from the guide 25, and the accommodation product can be arbitrarily changed by moving back and forth as shown in FIG.

  As shown in FIGS. 16 to 17, the ginger intake door 4 according to the present embodiment has a multiple structure, a large intake opening shape and a large diameter. It is indispensable for fishing gear operated by oneself and is the most important part for the survival of seafood. The intake net door 4 is constituted by a detachable and integrated fishing net with a door and is inexpensive and easy to operate. As shown in FIG. 18, the intake network door 4 at the time of intake operation accommodation is guided through a guide rail, and is opened by the weight of the door network when the stopper is removed.

  Also, door nets with different meshes can be easily replaced by preparing them in advance for replacement. Replacing the mesh of the mesh door is an indispensable function as an environmentally friendly fishing gear that prevents overfishing of small fish and facilitates escape of small fish.

  The fish tank having a ginger multiplex structure of this embodiment will be described with reference to the perspective view of FIG.

  In the ginger multiplex structure, the shape of the fish inlet mesh door 4 is about four times larger than the conventional one, and FIGS. 16 to 17 are explanatory views showing how the fish intake moves into the ginger. In addition to preventing fish from accumulating on the side of the vessel's catching net, it is possible to dramatically improve the survivability by taking in efficiently, and in order to operate itself like a light ginger, Increasing the size is indispensable and also enables the expansion of ginger volume. The ginger multiplex structure is only possible with the bellows type float 2 fish tank 18 installed type, but the fish tank separation movable power is possible with a series of power supply / exhaust power of the bellows type float 2, and in the separation part This is a simple operation of holding the locking stopper 27 and the like to hold the lock, etc. to keep the structure further, sinking when released and exhausting, and rising when further supplying air. In addition, these series of operations do not affect the towing speed.

  The above-described stability in the movable separation of the multiple structure will be described with reference to FIG.

  The ginger body 1 and the fish tank 18 of this embodiment are provided with guide pulleys 28 in the smoothly guided portions of the vertical bulkhead 15, the bow bulkhead 16, and the stern bulkhead 17, and after the arrival at the fishing ground, the fixed stopper is released, and the bellows When evacuation of the float 2 of the type is started, the ginger body 1 separates while sinking together with the fish tank 18, and stops at the stopper 27b. When air supply is started even at the time of ascent, the fish tank 18 stops at the stopper 27, and the multiple structure up / down operation is completed.

  Further, the method of separating and raising / lowering the multi-structure ginger body 1 and the fish tank 18 is not limited to the guide pulley 28. For example, a method of smoothly floating and sinking the bottom of the ship in a large elliptical shape, It is also preferable to use a method of guiding the role to the space between the ship side skin 13 and the vertical partition 15 with a double pipe structure as shown in FIGS.

  The larger the rear intake front aperture in the multiple structure described above, the smoother the intake operation and the better the work efficiency. In particular, in the case of a light ginger, the ginger itself is preferable to operate with a larger intake opening, and the deeper the water, the better the triple quadruple multiple structure. Since the ginger of this embodiment carries a large amount of collected fish in a swimming state, it is easy to improve added value such as shipping adjustment, and in the structural reform of the conventional fishing boat fishery, drastic reduction of fishing boats and labor is achieved. Contribute to the dissemination of environmentally-friendly fishing boats that can be realized.

  The towed ginger of the present invention not only for fishing boats but also for fishery associations, collects live fish and transports them in large quantities around the Tokyo metropolitan area. Is possible.

  As a matter of course, not only migratory fish but also other root fish, shellfish, salmon and the like can be transported with good yield, and aeration and seawater circulation can be provided in the fish tank.

  Further, for voyages such as sea areas where there are many ship navigations and high pollution concentrations, a completely sealed type in which the seawater circulation device is sealed or the blocking plate of the blocking door 7 is bitten with packing to increase the blocking density and tow is possible.

  In addition, a GPS device is installed in the event of a tough weather or bad weather during operational towing, and a function to collect it later is equipped.
