Description
本発明は、蛇捕獲装置に関する。さらに詳しくは、本発明は、蛇が電力用設備である変電所機器や送電鉄塔に昇搭することによって発生する電気的な地絡事故を防ぐことに有効な蛇捕獲装置に関する。 The present invention relates to a snake trapping device. More specifically, the present invention relates to a snake catching device effective in preventing an electrical ground fault caused by a snake ascending to a substation device or a transmission tower, which is an electric power facility.
変電所構内には、架空送電線から架線された電力線を受けるため鉄構と鉄材で組まれた架台や、その上部に設置される、断路器など種々の電力用機器が配置されており、これらの機器には、断路器の操作ロットとか構造用鋼材などの種々の縦向きに配置された部材がある。高い所へ昇る習性のある蛇は縦向きに配置された部材をたどって変電所設備の上部まで昇塔し、架線された電力線に接触して地絡事故を発生させる場合がある。 In the substation yard, various power equipment such as a disconnector installed on the pedestal made of steel structure and iron material to receive the power line laid from the overhead transmission line and these are arranged. The equipment includes various vertically arranged members such as an operation lot of a disconnector and a structural steel material. A snake that has a habit of ascending to a high place may follow vertically arranged members to ascend to the upper part of the substation equipment and come into contact with the overhead line to cause a ground fault.
これまで、蛇の昇塔を防止する技術には、多数のものがある。
特許文献１，２は、電撃を用いるものであるが、この従来技術は高価な設備を必要とする欠点がある。
特許文献３，４は、ローラを用いるものであるが、蛇がローラを迂回すると蛇の昇塔を防止することができない。
特許文献５〜７は、蓋状の容器を用いるものであるが、蛇の昇塔を邪魔することはできても捕獲することはできない。
特許文献８〜１０は、網カゴ等を用いるものであるが、蛇の昇塔を邪魔することはできても捕獲することはできない。
特許文献１１〜１５は、物理的な邪魔物を用いるものであるが、蛇の昇塔を邪魔することはできても捕獲することはできない。
So far, there are many techniques for preventing the ascent of snakes.
Patent Documents 1 and 2 use electric shock, but this conventional technique has a drawback that requires expensive equipment.
Patent Documents 3 and 4 use rollers, but if the snake bypasses the rollers, the ascending tower of the snake cannot be prevented.
Patent Documents 5 to 7 use a lid-shaped container, but they can interfere with the ascending tower of the snake but cannot capture it.
Patent Documents 8 to 10 use a net cage or the like, but they can interfere with the ascending tower of the snake, but cannot capture it.
Patent Documents 11 to 15 use physical obstacles, but they can interfere with the ascending tower of the snake but cannot capture it.
上記従来例は、蛇の昇塔を邪魔することはできても、捕獲はしないので一時的な効果にとどまる。ある程度長期的な効果を担うなら蛇を捕獲するのが効果的である。
本発明は上記事情に鑑み、棒状体を伝って移動する蛇を容易に捕獲できる蛇捕獲装置を提供することを目的とする。
In the above conventional example, although it is possible to interfere with the ascending tower of the snake, it is not captured, so it is only a temporary effect. If it has a long-term effect to some extent, it is effective to capture the snake.
In view of the above circumstances, it is an object of the present invention to provide a snake catching device capable of easily catching a snake moving along a rod-shaped body.
第１発明の蛇捕獲装置は、縦向きに設けられた棒材と、該棒材に外挿された捕獲容器とからなる蛇捕獲装置であって、前記捕獲容器は、該容器本体の上部に設けられた人為的に開閉可能な上蓋と、前記容器本体の下部に設けられた開閉可能な下蓋とを備えており、前記下蓋は、下方から上向きに加わる外力によって閉じる逆止め機能を有することを特徴とする。
第２発明の蛇捕獲装置は、第１発明において、前記上蓋および前記下蓋は、複数枚の弾力性のある板バネで構成されていることを特徴とする。
第３発明の蛇捕獲装置は、第１発明または第２発明において、前記捕獲容器の一部に内部を透視できる透視部が設けられていることを特徴とする。
第４発明の蛇捕獲装置は、第１発明または第２発明において、前記捕獲容器が、前記容器本体と前記上蓋とが着脱自在に構成されていることを特徴とする。
The snake catching device of the first invention is a snake catching device including a bar material provided vertically and a catching container extrapolated to the bar material, and the catching container is placed on an upper portion of the container body. It is provided with an artificially openable and closable upper lid and an openable and closable lower lid provided at the lower part of the container body, and the lower lid has a reverse stop function of closing by an external force applied upward from below. It is characterized by that.
The snake catching device of the second invention is characterized in that, in the first invention, the upper lid and the lower lid are composed of a plurality of elastic leaf springs.
The snake catching device of the third invention is characterized in that, in the first invention or the second invention, a see-through portion capable of seeing through the inside is provided in a part of the catching container.
The snake catching device of the fourth invention is characterized in that, in the first invention or the second invention, the catching container is configured such that the container body and the upper lid are detachably formed.
第１発明によれば、蛇は縦向きの棒材を昇る習性があるので、棒材を伝って捕獲容器に入ろうとする。このとき、蛇が下蓋を下方から上向きに押すと開くので容器本体内に入ってしまう。この下蓋は上から加えた下向きの力では開かない逆止め機能を有するので、蛇は容器本体内に閉じ込められたままとなる。この時点において、当該の蛇が上部に架線された電力線に接触して地絡事故を発生させるリスクをゼロにできる。また、一定期間経過後、上蓋を人為的に開けると捕獲した蛇を取り出すことができる。このようにして敷地内の蛇を捕獲していけば、周辺エリア内の蛇の絶対数が減るので昇塔確率を低減でき、その結果として地絡事故の防止効果が高くなる。
第２発明によれば、弾力性の板バネは簡単かつ軽量な構成で開閉できるので、捕獲容器が簡単となり、使い勝手が良くなる。
第３発明によれば、容器の内部を透視できるので、蛇の存否が確認しやすくなる。
第４発明によれば、上蓋を容器本体から取り外すと、容器本体内の蛇を容易に取り出すことができる。
According to the first invention, since the snake has a habit of climbing a vertically oriented rod, it tries to enter the capture container along the rod. At this time, when the snake pushes the lower lid upward from below, it opens and enters the container body. This lower lid has a reverse stop function that does not open with a downward force applied from above, so the snake remains trapped inside the container body. At this point, the risk of the snake coming into contact with the power line laid above and causing a ground fault can be eliminated. In addition, after a certain period of time, the captured snake can be taken out by artificially opening the upper lid. If the snakes on the site are captured in this way, the absolute number of snakes in the surrounding area will decrease, so the probability of ascending the tower can be reduced, and as a result, the effect of preventing ground faults will increase.
According to the second invention, since the elastic leaf spring can be opened and closed with a simple and lightweight configuration, the capture container becomes simple and the usability is improved.
According to the third invention, since the inside of the container can be seen through, it becomes easy to confirm the existence or nonexistence of the snake.
According to the fourth invention, when the upper lid is removed from the container body, the snake in the container body can be easily taken out.
つぎに、本発明の実施形態を図面に基づき説明する。
本発明の蛇捕獲装置は、蛇が縦向きの棒材を昇る習性を利用したものであるので、棒材に捕獲容器を取付ける構成が採用されている。本発明の蛇捕獲装置は、とくに変電所構内に設置される変電所機器や送電鉄塔を構成する縦向きの棒材に設置されるのが代表的であるが、適用対象が変電設備等に限られるものではない。
Next, an embodiment of the present invention will be described with reference to the drawings.
Since the snake catching device of the present invention utilizes the habit of a snake climbing a vertically oriented bar, a configuration in which a catching container is attached to the bar is adopted. The serpentine capture device of the present invention is typically installed on a vertical bar constituting a substation device or a power transmission tower installed in a substation premises, but the applicable target is limited to substation equipment and the like. It is not something that can be done.
（第１実施形態）
図１および図２に基づき、第１実施形態に係る蛇捕獲装置Ａを説明する。
図に示す棒材ｐは、変電所内に設置された断路器の操作ロッドが代表的なものである。この棒状ｐは常時は縦向きの状態となっている。
捕獲容器１は、円筒状の容器であり、棒材ｐに外挿されている。換言すれば、棒材ｐは捕獲容器１の内部に存している。
(First Embodiment)
The snake catching device A according to the first embodiment will be described with reference to FIGS. 1 and 2.
The rod material p shown in the figure is typically an operation rod of a disconnector installed in a substation. This rod-shaped p is always in a vertical orientation.
The capture container 1 is a cylindrical container and is extrapolated to the bar member p. In other words, the bar p is present inside the capture container 1.
捕獲容器１の容器本体１ａは上下高さは約５０ｃｍ以上、直径等は約２５ｃｍ以上のものである。捕獲容器１の上下高さが約５０ｃｍ以上であると、蛇が容器の外面を這い上がらなくなるので好ましい。また、捕獲容器１の直径が約２５ｃｍ以上であると、蛇が容器の外面を巻き付いて昇りにくくなるので好ましい。
捕獲容器１の材質にはとくに制限がないが、金属製の板バネと同一材料を用いるなら、ステンレススチールやアルミニウム、合成樹脂などが好適である。
捕獲容器１の外面は平滑にしておくとよい。平滑だと蛇がよじ昇りにくいからである。逆にいうと、段差や凹凸、小孔などは、蛇が昇りやすくなるので、避けるべきである。
The container body 1a of the capture container 1 has a vertical height of about 50 cm or more and a diameter or the like of about 25 cm or more. When the vertical height of the capture container 1 is about 50 cm or more, the snake does not crawl up on the outer surface of the container, which is preferable. Further, when the diameter of the capture container 1 is about 25 cm or more, the snake wraps around the outer surface of the container and is difficult to ascend, which is preferable.
The material of the capture container 1 is not particularly limited, but if the same material as the metal leaf spring is used, stainless steel, aluminum, synthetic resin, or the like is suitable.
The outer surface of the capture container 1 should be smooth. This is because if it is smooth, the snake will not easily rise. Conversely, steps, irregularities, small holes, etc. should be avoided because the snake tends to rise.
上蓋２は、金属製の板バネ３で構成されている。複数枚板バネ３が円周状に並べられ、板バネ３の基端部３ａが容器本体１ａに固定され、先端部３ｂが自由端となって、上向きに延び棒材ｐの外表面に接している。
板バネ３は弾力性があるので、自然な状態では先端部３ｂが棒材ｐの外面に接しており、上蓋２が閉じた状態となっている。しかし、人の手で先端部３ｂを押し開いて、上蓋２を開くこともできる。
The upper lid 2 is composed of a metal leaf spring 3. A plurality of leaf springs 3 are arranged in a circumferential shape, the base end portion 3a of the leaf spring 3 is fixed to the container body 1a, the tip end portion 3b becomes a free end, and extends upward and comes into contact with the outer surface of the bar member p. ing.
Since the leaf spring 3 has elasticity, the tip portion 3b is in contact with the outer surface of the bar member p in a natural state, and the upper lid 2 is in a closed state. However, the upper lid 2 can also be opened by pushing open the tip portion 3b by a human hand.
捕獲容器１の棒材ｐへの取付けは複数枚の板バネ３を棒材ｐへ沿わせておいて、適宜の締付け金具６で固定するのが簡便である。なお、締付け金具６の代りに針金や紐を用いてもよい。 To attach the capture container 1 to the bar p, it is convenient to place a plurality of leaf springs 3 along the bar p and fix them with appropriate tightening metal fittings 6. A wire or string may be used instead of the tightening metal fitting 6.
下蓋４は金属製の板バネ５で構成されている。複数枚の板バネ５が円周状に並べられ、板バネ５の基端部５ａが容器本体１ａに固定され、先端部５ｂが自由端となって上向きに延び棒材ｐに接近している。換言すれば、板バネ５の先端部は容器本体１ａにおける上下方向中間部分に位置している。
板バネ５は弾力性があるので、自然な状態では先端部５ｂが棒材ｐの外面に近接するか、軽く接触する状態となっている。
板バネ５は、下方から上向きに加わる外力によって開くので、棒材ｐを昇ってきた蛇が板バネ５を押し開いて、容器本体１ａの中に入ることができる。一方、容器本体１ａの中に入った蛇が板バネ５を自らの体で上方から下向きに力を加えても、板バネ５は開かない。この逆止め機能によって、蛇は容器本体１ａ内に閉じ込められた状態となる。
The lower lid 4 is composed of a metal leaf spring 5. A plurality of leaf springs 5 are arranged in a circumferential shape, the base end portion 5a of the leaf spring 5 is fixed to the container body 1a, and the tip end portion 5b becomes a free end and extends upward and approaches the bar member p. .. In other words, the tip of the leaf spring 5 is located in the vertical intermediate portion of the container body 1a.
Since the leaf spring 5 has elasticity, the tip portion 5b is in a state of being close to or lightly in contact with the outer surface of the bar member p in a natural state.
Since the leaf spring 5 is opened by an external force applied upward from below, the snake that has risen up the bar member p can push the leaf spring 5 open and enter the container body 1a. On the other hand, even if the snake inside the container body 1a applies a force to the leaf spring 5 downward from above with its own body, the leaf spring 5 does not open. By this reverse stop function, the snake is in a state of being confined in the container body 1a.
図３は、蛇の取出し要領を示している。上蓋２を固定している締付け金具６を外して、捕獲容器１を下向きに移動させ、手で開いた上蓋２から器具１０を差し込むと捕獲していた蛇を取り出すことができる。 FIG. 3 shows the procedure for taking out the snake. The captured snake can be taken out by removing the tightening metal fitting 6 fixing the upper lid 2, moving the capture container 1 downward, and inserting the instrument 10 from the upper lid 2 opened by hand.
（第２実施形態）
図４に基づき、第２実施形態の蛇捕獲装置Ｂを説明する。
本実施形態では、捕獲容器１の容器本体１ａに透視窓７を設けたものである。透視窓７は内部に蛇が居るかどうかを確認でき、蛇が逃げ出す程の隙間が無いものであればよい。
図示の例は、網目張りの透視窓７であるが、これ以外に小孔を多数設けたもの等を例示できる。
(Second Embodiment)
The snake catching device B of the second embodiment will be described with reference to FIG.
In the present embodiment, the perspective window 7 is provided in the container body 1a of the capture container 1. The perspective window 7 may be such that it can be confirmed whether or not there is a snake inside, and there is no gap enough for the snake to escape.
The illustrated example is a meshed see-through window 7, but in addition to this, a large number of small holes may be provided.
（第３実施形態）
図５に基づき、第３実施形態の蛇捕獲装置Ｃを説明する。
本実施形態では、棒材ｐに台座１１を取付け、植栽１２等を置いたものである。
この実施形態は、既存の変電設備の棒材（操作ロッドなど）を利用しないで、蛇捕獲のみを目的とした使用に向いている。
(Third Embodiment)
The snake catching device C of the third embodiment will be described with reference to FIG.
In the present embodiment, the pedestal 11 is attached to the bar p, and the planting 12 and the like are placed.
This embodiment is suitable for use only for the purpose of capturing snakes without using rods (operating rods, etc.) of existing substation equipment.
（第５実施形態）
図６に基づき、第５実施形態の蛇捕獲装置Ｄを説明する。
捕獲容器１は四面が四角形の立体容器である。図示の例では第１実施形態と同様の金属材料や合成樹脂材料で六面が構成されている。なお、図６では、捕獲容器１内部を破断して示している。
捕獲容器１の上面は、手で開閉できる上蓋２となっている。下蓋４は板バネ５製の進入口とその周囲の底板とからなる。
この実施形態は、棒材ｐが捕獲容器１の上蓋２を貫いておらず容器内に収まっている。
(Fifth Embodiment)
The snake catching device D of the fifth embodiment will be described with reference to FIG.
The capture container 1 is a three-dimensional container having quadrangular four sides. In the illustrated example, the six surfaces are made of the same metal material or synthetic resin material as in the first embodiment. In FIG. 6, the inside of the capture container 1 is broken and shown.
The upper surface of the capture container 1 is an upper lid 2 that can be opened and closed by hand. The lower lid 4 is composed of an entrance made of a leaf spring 5 and a bottom plate around the entrance.
In this embodiment, the bar material p does not penetrate the upper lid 2 of the capture container 1 and is contained in the container.
（その他の実施形態）
上記実施形態では、棒材ｐは断路器の操作ロッドに対応する部材であったが、これに限られず、縦向きに配置された棒状の部材であれば、どのような物も該当する。
図示の棒材ｐは全て断面が円形の棒状部材であったが、このような丸棒に限られることなく、断面が四角形や三角形、Ｌ形の棒材ｐにも本発明を適用できる。
(Other embodiments)
In the above embodiment, the rod member p is a member corresponding to the operation rod of the disconnector, but the present invention is not limited to this, and any rod-shaped member arranged in the vertical direction is applicable.
All of the illustrated bar members p are rod-shaped members having a circular cross section, but the present invention is not limited to such round bars, and the present invention can be applied to bar members p having a quadrangular, triangular, or L-shaped cross section.
本発明の他の実施形態として、捕獲容器１の容器本体１ａから上蓋２を取外しできるようにしたものも例示できる。上蓋２を取付け取外しできるようにしておくと、蛇の取り出しが容易にできるので好ましい。
上蓋２を容器本体１ａに取付けるための手段は任意であり、上蓋２（具体的な例としての板バネ３）の基部を容器本体１ａに取付け取外しできるのであれば、とくに制限なく採用でき、そのような例として適宜の留め金や係合器具、あるいはねじ込みや嵌合機構で取付け取外しできるものを例示できる。
なお、上蓋２の容器本体１ａに対する取付け取外し機構は、上蓋２全体だけでなく、上蓋２の一部を取付け取外し自在にするものであってもよい。
As another embodiment of the present invention, an example in which the upper lid 2 can be removed from the container body 1a of the capture container 1 can be exemplified. It is preferable that the upper lid 2 is attached and detached so that the snake can be easily taken out.
The means for attaching the upper lid 2 to the container body 1a is arbitrary, and if the base of the upper lid 2 (leaf spring 3 as a specific example) can be attached to and removed from the container body 1a, it can be adopted without particular limitation. As such an example, an appropriate clasp, an engaging device, or a device that can be attached and detached by a screwing or fitting mechanism can be exemplified.
The attachment / detachment mechanism of the upper lid 2 with respect to the container body 1a may be such that not only the entire upper lid 2 but also a part of the upper lid 2 can be attached / detached freely.
