【考案の詳細な説明】 （考案の対象、産業上の利用分野） 本考案は海苔網を洗浄する分野に利用される。[Detailed explanation of the idea] (Target of invention, industrial application field) The present invention is used in the field of cleaning seaweed nets.
本考案は海苔網の洗浄装置の改良に関するもの
である。 The present invention relates to an improvement of a cleaning device for seaweed nets.
（従来技術とその問題点）
一般に海苔養殖にあたつては海苔網に寄生する
雑草や網に付着した土砂、ノロ、雑菌を駆除する
ために、しばしば海苔養殖網を海中から引き上げ
て洗浄することが必要である。(Prior art and its problems) Generally, in seaweed farming, the seaweed farming nets are often lifted out of the sea and washed in order to eliminate weeds parasitic on the seaweed nets, as well as sediment, sludge, and various germs attached to the nets. is necessary.
この海苔網の洗浄については、実開昭51−
85000号公報および実公昭49−23120公報にその洗
浄手段が示されている。 Regarding the cleaning of this seaweed net,
85000 and Utility Model Publication No. 49-23120 disclose such cleaning means.
実開昭51−85000号公報に示されている海苔網
の洗浄手段は、上下に相対状態の分岐射水管を腕
体に枢支させると共に同射水管に軸方向の射水溝
を設け、同射水管の間に海苔網を通過させて洗浄
するものである。しかしこの洗浄手段には次の問
題点がある。 The means for cleaning seaweed nets shown in Japanese Utility Model Application Publication No. 51-85000 has branched water injection pipes that are vertically opposed to each other pivoted on the arm body, and the water injection pipes are provided with water injection grooves in the axial direction. A seaweed net is passed between the water pipes for cleaning. However, this cleaning means has the following problems.
(a) 噴水が射水管の軸方向に形成されている射水
溝から噴射されるため、海苔網に噴射される噴
水の方向は一方向だけである。したがつて海苔
網の上面は洗浄されるとしても海苔網の横面、
特に網の結束部には噴水が当りにくく十分な洗
浄が行なえない。(a) Since the fountain is sprayed from the water injection groove formed in the axial direction of the water injection pipe, the fountain is sprayed onto the seaweed net in only one direction. Therefore, even if the top surface of the seaweed net is washed, the side surface of the seaweed net,
In particular, it is difficult for the water fountain to hit the tied parts of the net, making it difficult to wash them thoroughly.
(b) 噴水は射水管の軸方向に形成されている射水
溝から噴射されるため７〜８Kg／cm2の噴水圧力
を上げないと噴水力が得られないが、このよう
な高圧ポンプは重量も重く、小型の箱船に積載
できない。(b) Since the fountain is injected from the water injection groove formed in the axial direction of the water injection pipe, the fountain force cannot be obtained unless the fountain pressure is increased by 7 to 8 kg/ cm2 . It was too heavy to be loaded onto a small ark.
(c) 射水管はコ状に形成されて上下に２本配置さ
れており、射水管の間に海苔網を通過させて洗
浄するが、海苔網は、第３図に示すようにロー
プで支柱に吊り下げられているため吊下げ箇所

できない。このためロープの箇所に来る度にロ
ープを支柱から取りはずさなければならず面倒
である。(c) The water injection pipes are formed in a U-shape and are arranged in two vertically, and the seaweed net is passed between the water injection pipes for cleaning.The seaweed net is supported by ropes as shown in Figure 3. The rope is in the way when passing through the hanging point, making it impossible for ships to pass through. For this reason, the rope must be removed from the support each time the rope is reached, which is troublesome.
また、実公昭49−23120号公報に示されている
洗浄手段は、回転するブラシとの接触によつて網
を洗浄するもので、吹つけられる水はブラシの汚
染を防ぐだけのものである。しかしブラシによつ
て網の掃除を行なうとブラシが網の表面を切削し
網を痛めてしまう。 Further, the cleaning means disclosed in Japanese Utility Model Publication No. 49-23120 cleans the net by contact with a rotating brush, and the water sprayed is only used to prevent contamination of the brush. However, when cleaning the net with a brush, the brush cuts the surface of the net and damages the net.

縁部は重なるため、海苔網には上方向からだけ
でなく斜め方向からも海水が噴射される。(a) have an upper water pipe and a lower water pipe connected to a branch pipe, with the upper water pipe having a downward direction so as to direct water toward the seaweed net passing between the upper water pipe and the lower water pipe; , The required number of water fountains are formed upwards in each of the lower water pipes.
A bulge is formed in the fountain, and an elongated fountain that produces a fan-shaped fountain is bored along the bulge surface in this bulge. The seawater sent from the water pipes forms a fountain that spreads out in a fan shape, and the edges of each fan-shaped fountain overlap, so the seaweed net can only be accessed from above. Seawater is also sprayed from diagonal directions.
したがつて、ブラシ等のように網を痛めるこ
となく水の噴射力と噴射方向によつて海苔網の
十分な洗浄が行なえる。 Therefore, the seaweed net can be sufficiently cleaned by the jetting force and direction of the water without damaging the net unlike a brush or the like.

続することができ、ロープを取り外す場合と比
較して作業の効率が格段に上がる。(b) The upper water supply pipe is removably connected to the branch pipe, and the branch pipe is equipped with a lock to stop the water supply to the upper water supply pipe.
Even if you come to the point where the seaweed net is connected to the support with a rope, there is no need to remove the rope from the support.
After tightening the kettle to stop the water, removing the upper water pipe and passing the rope through it, connect the upper water pipe to the branch pipe again and open the kettle to continue cleaning the seaweed net. Comparatively, work efficiency is greatly improved.
(c) 実開昭51−85000号公報に記載のものは噴水

８Kg／cm2以上の噴水圧力を上げないと十分な噴
水力が得られない。(c) In the case described in Utility Model Application Publication No. 51-85000, the fountain is only sprayed from the water injection groove formed in the axial direction of the water injection pipe, so the direction of the fountain sprayed onto the seaweed net is narrow. Only in one direction. Therefore, even if the water injection grooves are formed in a dotted line shape, the fountain will also be in a dotted line shape, and the cleaning efficiency of the seaweed net will not be good. In order to increase efficiency, it is necessary to provide the water injection groove along the entire axial length of the water injection pipe, but in this case
Sufficient fountain power cannot be obtained unless the fountain pressure is increased to 8 kg/cm 2 or more.
このような高圧ポンプは重量も重く、海苔網
洗浄に使用されるような小型の箱船に積載でき
ない。 Such high-pressure pumps are also heavy and cannot be loaded onto small arks such as those used for cleaning seaweed nets.
これに対して本考案は、噴水口には膨出部が

なえる。 In contrast, in the present invention, a bulge is formed in the fountain, and an elongated fountain that produces a fan-shaped fountain is bored along the bulge surface in this bulge. Therefore, the seawater sent to the water pipe becomes a fan-shaped fountain, and the edges of each fan-shaped fountain overlap, so seawater is sprayed onto the seaweed net not only from above but also from diagonal directions, resulting in a spray of 2 kg. /cm 2 pump can perform sufficient cleaning.
