Description

【0001】
【発明の属する技術分野】
本発明は、水生生物である甲殼類、魚類、貝類、藻類等の飼育・養成、種苗生産、餌料培養を効率的に行うための撹拌抑制具、およびその方法に関する。
【0002】
【従来の技術】
水生生物を飼育・養成するときは、通常水中に酸素を供給するが、その方法は、水槽底部または下部にエアストーン等を配置し、気体放散具にエアチューブをつなぎ、エアチューブの他端にはエアコンプレッサーをつなぎ、エアコンプレッサーから送気を行うことによるが、これらの器具類は、水槽・培養槽の深さに自在に対応できないものもあり、送気量が不適当となり水の激しい撹拌や逆に酸素を十分に供給できないこともあり、飼育・養成する水生生物にとっては必ずしも好ましくない現状がある。
【0003】
【発明が解決しようとする課題】
水中に酸素を供給する方法には、他に濾過器具も組み合わせ、酸素供給と同時に濾過機能をもたせたものもあるが、いずれも水槽内に水の撹拌を起こさせるが、撹拌を弱めるために送気を弱めると水中の溶存酸素量が不十分となるおそれがあり、いずれも飼育・養成する水生生物によっては良い環境といえない場合がある。
【0004】
また、水中に送気を行うときに発生する空気の泡が、水面で破裂するときに、水の飛沫を水槽外に飛散させるが、海水である場合や飼育・養成水に水生生物の餌としてクロレラを添加している場合は水槽の周辺を著しく汚損する。
【0005】
更に、市場に流通する水生生物を飼育・養成する水槽・培養槽の規格は現在多種多様で深さが一定でなく、使用する飼育器具類よっては深さの対応が不十分で、深さごとに飼育器具を揃えなくてはならない場合がある。
【0006】
本発明は、このような問題を解決することにあり、飼育・養成する水生生物に十分な酸素を供給すると同時に、水槽・培養槽内の水の撹拌を抑え、好適な飼育・養成環境をつくる伸縮自在撹拌抑制具を提供することにある。
【0007】
【課題を解決するための手段】
この目的を達成するための本発明による水生生物の伸縮自在撹拌抑制具の特徴手段は、上下浮動自在な伸縮パイプ1a、1bと、伸縮パイプ1a、1bの上部に放水用の放水口6を周面に開口し、放水口6の上部には、使用時に伸縮パイプ1a、1bが水中で直立浮上するための浮力を保つフロート7を取り付け、伸縮パイプ1aの上端面は着脱可能な蓋2で嵌合されている。伸縮パイプ1a、1bの上端部は排気・給餌・微量元素添加用の放気・注入口5を設け、伸縮パイプ1bの下端は取水口8となっており、支軸9が設けられた枠10を嵌合している。枠10にはフロック及び水生侵入防止用の網11を取り付け、支軸9に係留索12を取り付け、係留索12の他端に錘13を取り付け、多様な水深がある水槽・培養槽に使用するときに、伸縮パイプ1a、1b及びフロート7の浮力の働きにより上下浮動により自在に対応することを可能とし、伸縮パイプ1a、1b内で送気を行うことにより、飼育・養成水に十分な酸素を供給した後、伸縮パイプ1a、1b上部より放水し、余分な空気の泡は伸縮パイプ1a、1b内で破裂させ上面に設けられた放気・注入口5から排出させることにより飼育・養成水の撹拌を抑制しつつ十分な酸素を供給し、空気の泡の破裂による水槽外の汚損を防止することを特徴とする。
【0008】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づき詳細に説明する。
図1は、本発明の一部破断斜視図である。図2は、伸縮パイプ部を示す縦断面図である。
【0009】
伸縮自在撹拌抑制具は、図1より、伸縮パイプ1a、1bの口径の異なる2連の筒状構造からなり、パイプの口径は、伸縮パイプ1aで2cm〜30cm程度、伸縮パイプ1bでは、これより若干細くなっている。伸縮パイプ1aの上端面は着脱可能な蓋2により、使用時には嵌合され閉鎖されている。蓋2にはエアチューブ3が貫通している。エアチューブ3の先端には、エアストーン4が取り付けられおり、エアチューブ3により伸縮パイプ1aの内部にエアストーン4が垂下するようになっている。エアチューブ3及びエアストーン4は伸縮パイプ1aとほぼ同じか更に短くしたことにより、水圧がかかることによる送気量の減少を抑制している。また、蓋2には空気の放気及びクロレラ・微量元素注入用の放気・注入口5が開口している。また、伸縮パイプ1aの側面上部の周面には、放水口6が開口している。放水口6の上部には、フロート7が取り付けられている。尚、伸縮パイプ1a、1bの連結部分は、図2よりフランジによる構造となっている。
【0010】
図1より、伸縮パイプ1bの下端面は取水口8となっており、支軸9が設けられた枠10を嵌合している。枠10には網11を張り付けている。
【0011】
図1より、支軸9の中心には、長さの調節が可能な係留索12が取り付けられており、係留索12の他端には水槽・培養槽の底部に沈下させる錘13が固定されている。
【0012】
このような構成をもつ伸縮自在撹拌抑制具は、養成水(淡水・海水)が満たされた水槽・培養槽内に設置して使用する。伸縮自在撹拌抑制具を水槽・培養槽に設置すると、錘13により沈降し、伸縮パイプ1a、1b内部に養成水が浸水し満たされる。同時にフロート7の浮力により、伸縮パイプ1a、1bが、水中で直立し蓋2が水面と同一の高さで停止することとなる。尚、フロート7の材質は、伸縮パイプ1a、1bを水中で直立浮上させられるものなら材質、形状は問わない。また、フロート7の位置を調節することにより蓋2の位置は、水面上に出すことも、水中下にすることも可能である。
【0013】
エアチューブ3の他端から送気を行うと、エアチューブ3により垂下されたエアストーン4から細かい気泡が発生し伸縮パイプ1a、1b内を上昇する。気泡は上昇するときに、周囲の養成水を上昇させる働きがある。伸縮パイプ1a、1b内部で上昇した養成水は、放水口6から水槽・培養槽外へと排出される。放水口6の開口数は多いため排出される水流は分散し弱められ、水槽・培養槽全体に緩やかに拡散する。尚、放水口6の各々の口径は、飼育・養成する水生生物のサイズに応じて、自在に変更できる。また、交換式として口径を調節しても良く、網を張り付けても柵状の構造でも多数の小孔を持つパンチボード状の構造でも良い。
【0014】
伸縮パイプ1a、1b内部では、通気により激しく撹拌が行われているため、水槽・放水口6から流出した養成水は、水槽・培養槽で飼育・培養されている水生生物に十分な酸素を供給することとなる。また、通気をすることで、酸素の一部は水中に溶解するが、残りは気泡のまま上昇を続け、パイプ1aの上部に達し気泡は破裂し、放気・注入口5より放気される。気泡は破裂するときには、水槽・培養槽外まで養成水を飛散させ、養成水が海水や養成水にクロレラを添加していると、水槽・培養槽外の周辺を著しく汚損するが、伸縮自在撹拌抑制具では、パイプ1a内で気泡を破裂させるため、水槽・培養槽外の周辺を汚損することがない。放気・注入口5は、クロレラや微量元素を素早く拡散させるための注入口ともなっている。
【0015】
通気により伸縮パイプ1a、1b内の養成水が上昇し排出されたことにより、取水口8からは酸素の少ない水が新たに流入する。取水口8の周辺は、流入により水の流れが出来ているため、開放されたままでは伸縮パイプ1a、1b内部に水生生物が侵入するおそれがあるが、網11を取り付けたことによりこれらの侵入は防止できるようになっている。また、取水口8は係留索12により水槽・培養槽から離れて更に網11により、水槽・培養槽の底部に滞留するフロックの侵入・拡散防止の働きもある。尚、網11は、飼育・養成する水生生物のサイズに応じて、自在に交換することが可能である。網11は、網に限定するものではなく、網以外にも柵状の構造でも多数の小孔を持つパンチボード状の構造でも良い。
【0016】
水槽・培養槽は、市場には多種多様な形状や深さをもつものが流通し、水槽・培養槽内で使用する器具類によっては深さに対応できないものも存在するが、伸縮自在撹拌抑制具は、パイプ1aに取り付けたフロート7の浮力により自在に上下し、また係留索12の長さを調節することにより、どのような深さをもつ水槽・培養槽であっても対応が自在となっている。図1、図2、図3においては、伸縮パイプ1a、1bの比率は1:1であるが、1:1に限定するものではなく、一方のパイプを長くし、2:1としても3:1としても良い。伸縮パイプ1b内には濾材を入れ濾過機能を持たせても良い。また、錘13を軽くすることにより、伸縮自在撹拌抑制具を水槽、培養槽に浮遊させ使用することも可能である。尚、伸縮自在撹拌抑制具の各々の材質は、長時間使用しても変質せず、水生生物に有害な物質を放出しないものならどのようなものでも作製できる。使用目的によっては、一定時間経過後に自然に分解する材質であっても良い。伸縮パイプ1a、1bについては、筒状構造となるものであれば断面の形状は問わずあらゆる形状とすることが可能である。また、伸縮自在撹拌抑制具の使用目的は水生生物に限定せず、液体の混合、液体に気体を溶解させる目的等他の産業にも幅広く応用が可能である。
【0017】
【発明の効果】
本発明の完成により、多様な水深がある水槽・培養槽に使用するときに、伸縮パイプ1a、1b及びフロート7の浮力の働きにより上下浮動によりあらゆる水深の水槽・培養槽に自在に対応することが可能となった。また、伸縮パイプ1a、1b内で送気を行うことにより、飼育・養成水に十分な酸素を供給した後、伸縮パイプ上部より放水することで、飼育・養成水の撹拌を抑制しつつ十分な酸素を供給することが可能となった。更に、送気で発生した余分な空気の泡が、伸縮パイプ1a、1b内で破裂した後に上面に設けられた放気・注入口5から排出することにより、空気の泡の破裂による水槽外の汚損を防止することが可能となった。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a stirrer for efficiently breeding and cultivating aquatic organisms such as shellfish, fish, shellfish, and algae, producing seeds and seedlings, and cultivating feed, and a method thereof.
[0002]
[Prior art]
When breeding and cultivating aquatic organisms, oxygen is usually supplied to the water.However, the method is to place an air stone etc. at the bottom or lower part of the water tank, connect an air tube to a gas dispersing device, and connect the other end of the air tube to Is connected to an air compressor and air is supplied from the air compressor.However, some of these instruments cannot be adjusted to the depth of the water tank / culture tank, and the amount of air supplied is inappropriate, resulting in intense agitation of water. On the contrary, there is a case where oxygen cannot be supplied sufficiently, which is not always favorable for aquatic organisms to be reared and cultivated.
[0003]
[Problems to be solved by the invention]
There are other methods of supplying oxygen to the water, which are combined with a filtering device and have a filtering function simultaneously with the supply of oxygen.In all cases, water is stirred in the water tank. If the mind is weakened, the amount of dissolved oxygen in the water may become insufficient, and none of them may be a good environment depending on the aquatic organisms bred and nurtured.
[0004]
In addition, when air bubbles generated when air is blown into the water breaks up on the surface of the water, water droplets are scattered outside the water tank, but it is used as seawater or feed for aquatic organisms in breeding and training water. If chlorella is added, the surroundings of the water tank will be significantly contaminated.
[0005]
Furthermore, the specifications of aquariums and cultivation tanks for breeding and cultivating aquatic organisms distributed in the market are currently diversified and the depth is not constant. It may be necessary to arrange breeding equipment.
[0006]
The present invention is to solve such a problem, and supplies a sufficient amount of oxygen to aquatic organisms to be bred and cultivated, and at the same time, suppresses agitation of water in a water tank and a culture tank to create a suitable breeding and cultivation environment. An object of the present invention is to provide a retractable stirring suppressor.
[0007]
[Means for Solving the Problems]
In order to achieve this object, the characteristic means of the aquatic organism expansion / contraction stirrer according to the present invention comprises a vertically movable telescopic pipe 1a, 1b, and a water outlet 6 for discharging water at the upper part of the telescopic pipes 1a, 1b. At the top of the water outlet 6, a float 7 for maintaining the buoyancy of the telescopic pipes 1a and 1b to float upright in water during use is attached, and the upper end face of the telescopic pipe 1a is fitted with a removable lid 2. Have been combined. The upper ends of the telescopic pipes 1a and 1b are provided with an air discharge / injection port 5 for exhaust / feed / trace element addition, and the lower end of the telescopic pipe 1b is a water intake 8 and a frame 10 provided with a support shaft 9. Are fitted. A net 10 for preventing flock and aquatic invasion is attached to the frame 10, a mooring line 12 is attached to the support shaft 9, and a weight 13 is attached to the other end of the mooring line 12, which is used in a water tank or a culture tank having various water depths. At the same time, the buoyancy of the telescopic pipes 1a, 1b and the float 7 makes it possible to freely cope with up and down floating, and by supplying air inside the telescopic pipes 1a, 1b, sufficient oxygen for breeding / cultivation water is provided. Is supplied from the upper part of the telescopic pipes 1a and 1b, and excess air bubbles are ruptured in the telescopic pipes 1a and 1b and discharged from the air release / injection port 5 provided on the upper surface to breed and grow water. It is characterized in that sufficient oxygen is supplied while suppressing agitation of the water, thereby preventing contamination outside the water tank due to bursting of air bubbles.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a partially cutaway perspective view of the present invention. FIG. 2 is a longitudinal sectional view showing the telescopic pipe section.
[0009]
As shown in FIG. 1, the telescopic stirring suppressor has a double tubular structure with different diameters of the telescopic pipes 1a and 1b. The diameter of the pipe is about 2 cm to 30 cm for the telescopic pipe 1a, and for the telescopic pipe 1b. It is slightly thinner. The upper end surface of the telescopic pipe 1a is fitted and closed by a removable lid 2 at the time of use. An air tube 3 passes through the lid 2. An air stone 4 is attached to the tip of the air tube 3 so that the air stone 3 hangs inside the telescopic pipe 1a. Since the air tube 3 and the air stone 4 are substantially the same as or shorter than the telescopic pipe 1a, a decrease in the air supply amount due to the application of water pressure is suppressed. Further, the lid 2 is provided with an air release / injection port 5 for air release and chlorella / trace element injection. Further, a water outlet 6 is opened on the upper peripheral surface of the telescopic pipe 1a. A float 7 is attached to an upper part of the water outlet 6. The connecting portion between the telescopic pipes 1a and 1b has a flange structure as shown in FIG.
[0010]
As shown in FIG. 1, the lower end surface of the telescopic pipe 1b is a water intake port 8, and the frame 10 provided with the support shaft 9 is fitted therein. A net 11 is attached to the frame 10.
[0011]
As shown in FIG. 1, a tether 12 whose length can be adjusted is attached to the center of the support shaft 9, and a weight 13 that sinks to the bottom of the aquarium / culture tank is fixed to the other end of the tether 12. ing.
[0012]
The telescopic stirring suppressor having such a configuration is installed and used in a water tank or a culture tank filled with training water (fresh water or seawater). When the telescopic stirring suppressor is installed in the water tank / culture tank, it sinks by the weight 13 and the inside of the telescopic pipes 1a and 1b is flooded and filled with training water. At the same time, due to the buoyancy of the float 7, the telescopic pipes 1a and 1b stand upright in the water, and the lid 2 stops at the same height as the water surface. The material and shape of the float 7 are not limited as long as the telescopic pipes 1a and 1b can be raised upright in water. Further, by adjusting the position of the float 7, the position of the lid 2 can be set above the water surface or under the water.
[0013]
When air is supplied from the other end of the air tube 3, fine air bubbles are generated from the air stone 4 hung by the air tube 3 and rise in the telescopic pipes 1 a and 1 b. When the bubbles rise, they act to raise the surrounding training water. The training water that has risen inside the telescopic pipes 1a and 1b is discharged from the water outlet 6 to the outside of the water tank / culture tank. Since the water outlet 6 has a large numerical aperture, the discharged water flow is dispersed and weakened, and diffuses gently throughout the water tank / culture tank. In addition, the diameter of each of the water outlets 6 can be freely changed according to the size of the aquatic organism to be reared and cultivated. Further, the diameter may be adjusted as an exchange type, and a net may be attached, a fence-like structure or a punch board-like structure having a large number of small holes may be used.
[0014]
Since the inside of the telescopic pipes 1a and 1b is vigorously stirred by ventilation, the training water flowing out of the water tank / water outlet 6 supplies sufficient oxygen to aquatic organisms bred and cultured in the water tank / culture tank. Will be done. Further, by aeration, a part of oxygen is dissolved in water, but the rest continues to rise as bubbles, reaches the upper part of the pipe 1a, bursts, and is discharged from the discharge / injection port 5. . When the bubbles burst, the training water is scattered to the outside of the water tank / culture tank.If the training water adds chlorella to the seawater or the training water, the surroundings outside the water tank / culture tank are markedly polluted. In the suppressor, the bubbles are ruptured in the pipe 1a, so that the surroundings outside the water tank and the culture tank are not stained. The air release / injection port 5 is also an injection port for quickly diffusing chlorella and trace elements.
[0015]
Since the training water in the telescopic pipes 1a and 1b rises and is discharged by the ventilation, water with little oxygen newly flows in from the water intake port 8. Water flows around the intake port 8 due to inflow, and aquatic organisms may enter the telescopic pipes 1a and 1b if left open. Can be prevented. Further, the water intake 8 is separated from the water tank / culture tank by the mooring cable 12 and further has a function of preventing the invasion / diffusion of flocs staying at the bottom of the water tank / culture tank by the net 11. In addition, the net 11 can be freely exchanged according to the size of the aquatic organism to be reared and cultivated. The net 11 is not limited to the net, but may be a fence-shaped structure or a punch board-shaped structure having a large number of small holes other than the net.
[0016]
Aquariums and culture tanks have a wide variety of shapes and depths on the market, and there are some that cannot be adjusted to the depth depending on the equipment used in the aquariums and culture tanks. The tool can freely move up and down by the buoyancy of the float 7 attached to the pipe 1a, and by adjusting the length of the mooring line 12, it can be used in any water tank or culture tank having any depth. Has become. In FIGS. 1, 2 and 3, the ratio of the telescopic pipes 1a and 1b is 1: 1. However, the ratio is not limited to 1: 1. It may be 1. A filter medium may be provided in the telescopic pipe 1b to have a filtering function. Further, by making the weight 13 lighter, it is possible to float and use the retractable stirring suppressor in a water tank or a culture tank. In addition, each material of the retractable stirring suppressor can be made of any material that does not deteriorate even after long-term use and does not release substances harmful to aquatic organisms. Depending on the purpose of use, a material that decomposes naturally after a certain period of time may be used. The telescopic pipes 1a and 1b can have any shape as long as they have a cylindrical structure, regardless of their cross-sectional shapes. In addition, the purpose of use of the extendable stirring suppressor is not limited to aquatic organisms, but can be widely applied to other industries such as mixing liquids and dissolving gas in liquids.
[0017]
【The invention's effect】
With the completion of the present invention, when used in water tanks and culture tanks having various water depths, the telescopic pipes 1a and 1b and the float 7 can be used to freely respond to water tanks and culture tanks of any depth by vertically floating by the action of buoyancy. Became possible. Further, by supplying air in the telescopic pipes 1a and 1b, sufficient oxygen is supplied to the breeding / cultivation water, and then water is discharged from the upper part of the telescopic pipe. It became possible to supply oxygen. Furthermore, the excess air bubbles generated by the air supply are expelled from the air release / injection port 5 provided on the upper surface after being ruptured in the telescopic pipes 1a and 1b. It has become possible to prevent fouling.
