[0010]
Further, it is preferable to use a pump for pumping up and spraying the cleaning liquid in the processing liquid tank through which the laver net is immersed and passed. Thereby, the laver net and laver can be cleaned using the cleaning liquid in the processing liquid tank.
[0011]
Further, as the treatment liquid tank, a treatment liquid tank of an activation treatment mechanism in which a treatment liquid for performing an activation treatment on a laver net is stored, and the lower member in the rope passing device is provided on both sides of the treatment liquid tank. A laver net immersed body is provided on each of the two sides, in which the laver net passing through the upper part of the processing liquid tank together with the ropes constituting the laver cultivation facility is pressed down and dipped into the processing liquid in the processing liquid tank. It is good to arrange so that it may be supported by an upper member. Thus, laver nets and laver can be cleaned using the cleaning liquid in the processing liquid tank, and an activation process can be performed with the processing liquid in the processing liquid tank.

The member 7 is held at a fixed position with respect to the guide member 6. The upper member 7 has lower curved portions 10, 10 which are curved so as to protrude downward at two front and rear portions of two parallel main rods 9, 9, and each of the lower curved portions 10 is connected in the middle of bending. The two connecting members 11 and 11 are connected and integrated by an intermediate rod 12 which is slightly curved so as to protrude downward in parallel with the main rod 9. It is placed so as to straddle the guide member 6 by the two left and right lower curved portions 10, 10. Further, the front end of each main rod 9 is connected to one point, and a guide rod 9a for guiding the hanging rope Ba reliably between the lower curved portion 10 and the guide member 6 extends forward. Each of the lower curved portions 10 has a function of allowing the suspension rope Ba to pass therethrough and engaging the guide member 6 to prevent the upper member 7 from moving in the left-right direction. Further, a stopper 13 is provided at a position behind the intermediate rods 12 of the guide member 6 so as to engage with the intermediate rods 12 to prevent the upper member 7 from moving backward. Further, the upper member 7 is prevented from moving upward by its own weight. Therefore, the upper member holding mechanism 8 in the present embodiment is formed by an engaging portion between the guide member 6 and each lower curved portion 10, an engaging portion between the intermediate rod 12 and the stopper 13, and the weight of the upper member 7.

Further, as exemplified by chain lines in FIGS. 3 and 6, in order to prevent the processing liquid 4 from swaying in the left-right direction, a flat plate having a large number of holes formed by punching metal or the like at the upper part of each immersion bar 15 is used. It is preferable to fix the processing liquid swing prevention member 20 in such a manner that the processing liquid fluctuation prevention member 20 is provided upright.
[0023]
Next, the activation processing mechanism 1 will be described with reference to FIG. The activation treatment mechanism 1 of the present embodiment performs an activation treatment by bringing a seawater electrolysis means 32 that electrolyzes seawater or the like into an electrolysis product liquid 4 into contact with the laver net B and the electrolysis product solution 4. It is formed by the contact processing means 33.
[0024]
One seawater electrolysis means 32 includes an electrolytic cell 34. The electrolytic cell 34 is filled and supplied with a predetermined amount of an electrolytic solution that has been generated to a predetermined concentration in advance. As shown in FIG. 8, the seawater 37 can be pumped up by the pump 35 via the switching valve 35a and the water suction pipe 36a, so that the seawater can be locally procured. Further, an anode plate 38 and a cathode plate 39 are disposed facing each other in the electrolytic cell 34, and are formed so that a positive potential and a negative potential are respectively supplied from power supply means (not shown). Between the anode plate 38 and the cathode plate 39, a partition wall 40 that divides the electrolytic cell 34 into an anode cell 41 and a cathode cell 42 as necessary is detachably formed. When the partition 40 is installed, a super acidic solution is generated in one anode tank 41, and a super alkaline solution is generated in the other cathode tank 42. To form a solution containing sodium hypochlorite. From the anode tank 41 and the cathode tank 42, a super-alkali solution and a super-acid solution or a solution containing sodium hypochlorite are supplied to one treatment liquid storage tank 47 through supply pipes 45 and 46 provided with pumps 43 and 44, respectively. It is formed so that it is supplied to. Further, the processing liquid is formed so as to be supplied from the processing liquid storage tank 47 to the processing liquid storage section 18 of the processing liquid tank 2 by a supply pipe 49 provided with a pump 48. Further, any one of a super-alkaline solution, a super-acid solution and a solution containing sodium hypochlorite is selectively supplied to the treatment liquid storage tank 47 in accordance with the purpose of the activation treatment.
[0025]
Next, the cleaning liquid spraying device K will be described with reference to FIGS. Various cleaning liquids can be used for the cleaning liquid spraying device K. For example, seawater or freshwater that can be directly procured at the aquaculture site, a treatment liquid such as an acid agent or an activator used for activation treatment applied to laver net B or laver, and a mixture of hydrochloric acid with seawater or freshwater. It is preferable to select an electrolysis solution from the solution according to the purpose of washing, the object to be washed, and the like. The cleaning liquid spraying device K of the present embodiment is supported by the upper member 7 of the rope passing device 3 and is directed toward the laver net B using the processing liquid 4 in the processing liquid tank 2 of the activation processing mechanism 1 as cleaning water. It is formed so as to be scattered. That is, the processing liquid provided above the plurality of immersion bars 15 of the laver net immersion body 5 attached to the connecting rods 14 bridged between the main rods 9, 9 of the pair of left and right upper members 7, 7. A cleaning liquid supply pump 52 with a drive source for supplying the processing liquid 4 as a cleaning liquid is mounted so as to extend over the swing preventing member 20, and the processing liquid 4 is pumped to one inlet side of the cleaning liquid supply pump 52. A pipe 53 is connected, and a spray pipe 54 is connected to the other outlet side. The cleaning liquid supply pump 52 has a self-drive source such as a battery and an engine. The one pumping pipe 53 is formed so that its pumping end is submerged in the processing liquid 4 in the processing liquid storage unit 18. The other spray pipe 54 is formed to have a length extending over the entire width of the processing liquid storage section 18 and is disposed so as to bridge between the plurality of immersion bars 15 at the position of the overflow section 19 in front. I have. A number of spray nozzles 55 for spraying seawater are provided on the lower surface of the spray pipe 54. In addition, using a submersible pump as the cleaning liquid supply pump 52, the cleaning liquid supply pump 52 is attached to the immersion bars 15, 15 of the laver net immersion body 5 and is installed in the processing liquid 4 in the processing liquid storage unit 18, and the hose 53 is omitted and directly. It may be formed so as to pump seawater. The supply of the processing liquid 4 to the processing liquid storage section 18 of the processing liquid tank 2 is performed by the system shown in FIG.
[0026]
Next, the operation of the present embodiment having the above-described configuration will be described.
[0027]
First, a case where the laver net B and the laver are cleaned using the cleaning liquid spraying apparatus K will be described. For example, when cleaning is performed using seawater as the cleaning liquid, a required amount of seawater is supplied to the processing liquid storage unit 18 of the processing liquid tank 2 via the pump 35, the switching valve 35a, and the water absorption pipe 36b. In a state where a plurality of laver nets B are stacked and raised in a laver farming facility, when the laver work boat A goes under the laver nets B, the laver nets B are scooped up on the boat, and the suspension ropes of the laver nets B Ba moves rearward on the guide member 6 and reaches the lower curved portion 10 of the main rod 9 of the rope passing device 3, as shown in FIG. By moving rearward while lifting the lower bending portion 10 against the total weight of the passing device 3, the laver net dipping body 5 and the washing liquid spraying device K, the space between the lower bending portion 10 and the guide member 6 is smoothed. Pass through. Since only the suspension line Ba passes between the lower curved portion 10 and the guide member 6, the upward force for lifting the upper member 7 by the suspension line Ba is relatively small. The upper member 7 is always kept at a fixed position with respect to the guide member 6 by the mechanism 8. Thereafter, the suspension rope Ba similarly passes between the lower curved portion 10 of each upper member 7 and the guide member 6. At this time, the cleaning liquid supply pump 52 is driven to pump up the seawater in the processing liquid storage section 18 of the processing liquid tank 2 from the pumping pipe 53, and as shown in FIGS. By spraying the seawater downward toward the laver net B, dust such as diatoms adhering to the laver net B and the laver can be reliably removed. The laver net B from which diatoms and the like have been removed proceeds to the rear of the ship and is spread again on the sea surface. At the time of seeding with little or no seaweed leaf, the watering strength from the nozzle 55 is increased. It is advisable to adjust the watering strength slightly.
[0028]
Further, in the above-described embodiment, since seawater which is kind to laver and is inexhaustible is used as the cleaning liquid, the laver can be cleaned without harming the laver, and the cost can be reduced. Of course, a cleaning liquid other than seawater can also be used.
[0029]
Next, a case will be described in which the partition wall 40 is provided in the electrolytic cell 34 and the super acidic solution or the super alkaline solution is supplied to the processing liquid tank 4 in the activation processing mechanism 1. When a positive potential and a negative potential are applied to the anode plate 38 and the cathode plate 39 at the nori cultivation site, seawater is electrolyzed in the electrolytic cell 34, and HCl is contained in the anode tank 41 due to the presence of the partition wall 40. A super-acidic solution having a pH of 2.7 or less is generated, and a super-alkaline solution having a pH of 11 or more made of NaOH is generated in the cathode tank 42. One of the super-acidic solution and the super-alkaline solution thus generated is temporarily stored in the processing liquid storage tank 47 from the anode tank 41 and the cathode tank 42 through supply pipes 45 and 46 provided with pumps 43 and 44, respectively. Then, the liquid is supplied to the processing liquid storage section 18 of the processing liquid tank 2 through the supply pipe 49 by the pump 48. The super-acidic solution and the super-alkaline solution may be appropriately diluted with seawater according to the state of the leaf body of the laver.
[0030]
Next, the case where the solution containing sodium hypochlorite is supplied to the treatment liquid tank 4 in the activation treatment mechanism 1 without disposing the partition wall 40 in the electrolytic cell 34 will be described. When a positive potential and a negative potential are applied to the anode plate 38 and the cathode plate 39 in the same manner as described above, electrolysis of seawater is performed in the electrolytic cell 34, and the anode plate 38 A solution containing slightly alkaline sodium hypochlorite (NaClO) is generated between the cathode plate 39 and the cathode plate 39. The solution containing the weakly alkaline sodium hypochlorite (NaClO) thus generated is stored in the processing liquid from the electrolytic cell 34 through the supply pipes 45 and 46 provided with the pumps 43 and 44 (either one may be used). The liquid is temporarily stored in the tank 47, and then supplied to the processing liquid storage section 18 of the processing liquid tank 2 through the supply pipe 49 by the pump 48.
[0031]
In this way, the processing liquid tank 2 is filled with the processing liquid 4 composed of the electrolysis solution of the seawater, and when the laver work boat A goes under the laver net B, the laver net B The immersion bar 15 of the laver net immersion body 5 is pressed downward from above by the immersion bars 15 and 15 in the processing liquid storage section 18 of the processing liquid tank 2 and is forcibly immersed in the processing liquid 4 to perform appropriate activation processing. Is done.
[0032]
In this way, the rope passing device 3 allows the suspension rope Ba to pass, and can maintain the relative positional relationship between the treatment liquid tank 2 and the laver net immersion body 5 at a fixed position. Since the shaking can be prevented, and the relative positional relationship between the laver net B and the laver net dipping body 5 can be maintained at a fixed position, the activation processing on the laver net B is always appropriate. Can be. Further, in the present embodiment, when the processing liquid oscillation preventing member 20 fixed to the immersion bar 15 and the processing liquid tank 2 shakes together with the laver net work boat A, the processing liquid in the processing liquid tank 2 Fluctuation of the liquid 4 can be suppressed to a small extent, whereby irregular movement of the processing liquid 4 can be reliably prevented. Thereby, the fluctuation amount of the center of gravity caused by the shaking of the processing liquid 4 is suppressed, the stability of the laver work boat A is improved, and the laver net B is immersed securely in the processing liquid 4 in the processing liquid tank 2. By doing so, the activation treatment for the laver net B can always be performed uniformly. Since the rope passing device 3 in this embodiment is formed by combining rod materials, a complicated mechanism is not required, the configuration is simple, the weight is low, the cost is very low, and the suspension rope is further reduced. Ba can be passed smoothly. In addition, the configuration of the laver net dipped body is not limited to the above embodiment, and can be changed.
[0033]
As described above, according to the present embodiment, as the laver work boat A advances, the laver is cut from the laver net B by the reaper F, and then the laver net B is immersed by the laver activation processing device G. While dipping under the body 5 and being immersed in the treatment liquid 4, the cut laver net B is uniformly subjected to the activation treatment with the electrolysis solution of seawater, and furthermore, the rear guide member projecting from the stern. During the relative movement to the rear end of I, the treatment liquid 4 consisting of the electrolysis solution of seawater is sufficiently penetrated into the laver cells, and by sterilizing various germs attached to the leaves, the proper treatment is achieved. Activation processing is performed. Alternatively, the rear guide member I may be contracted, and after uniformly performing the activation treatment using the electrolysis solution of seawater, the laver net may be returned to the sea surface and expanded.
[0034]
As described above, by performing the laver activation treatment method using the laver work boat A of the present invention, the laver net B after the laver is cut can be subjected to the electrolysis of seawater while in the air on the laver work boat A. The active treatment is performed using the produced liquid, and after the surface is floated for a time effective for the active treatment, it is returned to the sea surface, so that the nori can be grown healthy. In addition, since the seawater electrolysis product is used, the seawater electrolysis product that is attached to the laver net and brought into the seawater is originally seawater, so it may induce seawater contamination. It is also environmentally friendly, and can be used to activate the laver using a material that does not cause any environmental destruction.There is no need to prepare a special acid agent for the activation, and it remains after the activation. The resulting electrolyzed solution of seawater can be returned to the sea, resulting in low cost and easy handling. Furthermore, when a solution containing sodium hypochlorite is used as the electrolysis solution, hypochlorous acid is not decomposed in a short time, and does not adversely affect the environment. In addition, there is no need to carry the acid agent to the site on the ship or bring back the acid agent after the acid treatment, so that the weight and speed of the ship can be reduced.
[0035]
Further, an acid agent or an alkali agent may be used in addition to the electrolysis solution of seawater, or the pH may be adjusted. Alternatively, an agent such as an acid agent may be used instead of the electrolysis solution of seawater. You may do so.
[0036]
As described above, in the present embodiment, only by propelling the laver work boat A, the laver net B spread in the seawater by the guide member is formed on the ship, and the effective cleaning processing and activation processing are automatically performed. And re-spread in seawater, improving the efficiency of raising seaweed seedlings and harvesting rate, and promoting healthy seaweed cultivation, improving work efficiency, saving labor and labor. Can be achieved.
[0037]
In the above-described embodiment, the laver net B is immersed in the treatment liquid tank 2 as the activation processing mechanism 1, but an electrolysis product liquid may be injected into the laver net B, for example.
[0038]
Further, the present invention is not limited to the above-described embodiment, and can be changed as needed.
[0039]
【The invention's effect】
As described above, since the laver work boat of the present invention is constituted, the laver net and laver are washed to prevent pollution by diatoms, and active against the laver net and laver while in the air on the ship. In addition to performing the treatment, the surface is floated for a time effective for the activation treatment and then returned to the surface of the sea, so that healthy growth of laver can be achieved and the cost can be reduced.
[0040]
Specifically, the laver cultivation boat is advanced under the laver cultivation facility, which is spread on the sea surface, so as to pass through the lower surface of the laver net, and the laver cultivation is performed while the laver net is relatively moved from the bow to the rear of the hull. For the laver net passing along with the ropes constituting the facility, while in the air on the laver work boat, the cleaning liquid is sprayed from above by the cleaning liquid spraying device installed on the upper member of the rope passing device. By spraying, the laver net and the laver growing thereon can be washed well, and contamination by diatoms or the like can be prevented.
[0041]
When a pump for pumping up and spraying the cleaning liquid in the processing liquid tank through which the laver net is immersed and passed is used as the cleaning liquid spraying apparatus, the laver net and laver can be washed using the cleaning liquid in the processing liquid tank.
[0042]
Further, by providing an active treatment mechanism so as to use the treatment liquid tank of the activation treatment mechanism in which the treatment liquid for performing the activation treatment on the laver net is stored as the treatment liquid tank, the cleaning liquid in the treatment liquid tank is provided. It can be used to wash laver nets and laver, and can also be activated by a treatment solution.
[0043]
Further, seawater may be used as the cleaning liquid. Thus, the seaweed net and the seaweed can be washed using the seawater pumped into the treatment liquid tank.
[0044]
Further, by using the treatment liquid as a chemical or a solution of seawater electrolysis generated, the activation treatment can be favorably performed with a treatment liquid composed of the drug or the seawater electrolysis generated liquid.
[0045]
In addition, by installing a reaper on the laver work boat to cut the laver from the laver net, it automatically activates the laver net and laver and cuts the laver while the laver work boat dives under the laver net. It can be performed very well.
