Description

漏水検知センサ用構造体及びそれを備えた漏水検知センサStructure for leak detection sensor and leak detection sensor equipped with it
　本発明は、実験動物が飼育されるケージに設けられる漏水検知センサ用構造体及びそれを備えた漏水検知センサに係るものである。 The present invention relates to a structure for a water leakage detection sensor provided in a cage in which an experimental animal is bred and a water leakage detection sensor provided with the structure.
　従来から、教育や研究、生物学的製剤の製造等の科学上の利用に、実験動物が広く用いられてきた。 Traditionally, experimental animals have been widely used for scientific purposes such as education, research, and the manufacture of biopharmacy.
　実験動物の代表例としては、マウスやラット、モルモット、ウサギ、イヌ等が挙げられる。そして、これらの実験動物は、専用のケージの中で飼育される。 Typical examples of experimental animals include mice, rats, guinea pigs, rabbits, dogs, and the like. Then, these experimental animals are bred in a dedicated cage.
　ところで、このケージ内部には、通常、実験動物の飲み水を確保するための給水管が引き込まれており、実験動物が、その先端部を突っつくことにより給水が行われる構成となされている。 By the way, a water supply pipe for securing drinking water for the experimental animal is usually drawn into the cage, and the experimental animal is configured to supply water by poking the tip of the pipe.
　ここで、実験動物が、給水管の先端部を齧る、先端部にケージ内の木くず等床材を詰める、といった行動をすることにより、給水管から常時給水が行われ、漏水状態となる事態が生じることがあった。
　そして、実験動物の管理者がこの事態に気付かず、長時間経過してしまうと、ケージ内部が水没し、実験動物の生命を脅かしてしまう、という問題があった。 Here, when the experimental animal takes actions such as biting the tip of the water supply pipe and filling the tip with flooring material such as wood chips in the cage, water is constantly supplied from the water supply pipe, resulting in a water leakage state. It could happen.
Then, if the manager of the experimental animal does not notice this situation and a long time has passed, the inside of the cage will be submerged and the life of the experimental animal will be threatened.
　このような問題点を解決するために、特許文献１には、自動給水器の先端部から漏水してしまう事態を防止するための、実験用動物飼育装置に関する発明が記載されている。 In order to solve such a problem, Patent Document 1 describes an invention relating to an experimental animal breeding device for preventing a situation in which water leaks from the tip of an automatic water dispenser.
　この実験用動物飼育装置は、ケージ内部に金属線格子が収容される。この金属線格子には、実験動物が運動する飼育室側と水呑室側とに区画する、金属網の仕切板が取り付けられており、この仕切板によって、実験動物のけとばす木くずが水呑室に入らないように構成されている。
　そして、実験動物が水を飲む際には、仕切板に設けられた穴に自身の頭部を挿入し、ケージ内部に挿入された自動給水器の先端部を咥えることで、水呑細管先端より少しずつ出る水を飲むことができる。 This laboratory animal breeding device houses a metal wire grid inside the cage. This metal wire grid is equipped with a metal net partition plate that divides the laboratory animal into the breeding room side and the drinking room side, and this partition plate allows the experimental animal's scraps of wood to enter the drinking room. It is configured not to.
Then, when the experimental animal drinks water, it inserts its own head into the hole provided in the partition plate and holds the tip of the automatic water dispenser inserted inside the cage, so that it can be used from the tip of the water swallowing tube. You can drink the water that comes out little by little.
　また、自動給水器の水呑細管口は、水呑細管口を覆う外管の先端部より少し内方に後退させて構成されている。
　これにより、実験動物が水を飲む際、外管の先端部より漏れた水を、外管内を通して自動給水器の基部に取付けられたＵ字形トラップを経てケージ外部に流出させ、ケージ内部には漏水しないように構成されている。 Further, the water swallowing pipe mouth of the automatic water dispenser is configured to be slightly retracted inward from the tip of the outer pipe covering the water swallowing pipe mouth.

　図６に示すように、被覆体Ｂは、空間エンリッチメント取付け部Ｂ１ｂにより空間エンリッチメントＥを取付けることができる。 As shown in FIG. 6, the covering body B can be fitted with the space enrichment E by the space enrichment mounting portion B1b.
　ここで、「空間エンリッチメント」とは、実験動物の正常な行動の多様性を引き出し、異常行動を減らすことで、実験動物の福祉と健康を改善するために用いられる、遊具や床材、梁等の構造体のことである。
　本実施形態では、空間エンリッチメントＥは、下面が開放された略コ字状部材であり、被覆体Ｂに取付けられることで、トンネル状の構造体を形成する。 Here, "spatial enrichment" refers to play equipment, flooring materials, and beams used to improve the welfare and health of laboratory animals by drawing out the diversity of normal behaviors of laboratory animals and reducing abnormal behaviors. It is a structure such as.
In the present embodiment, the space enrichment E is a substantially U-shaped member having an open lower surface, and is attached to the covering body B to form a tunnel-shaped structure.

　図７は、漏水検知センサＳのＰＰ´線断面図であり、（ａ）は、被覆体Ｂのみを分解した状態を示している。また、図７では、配置面Ｇを、仮想的に直線により示している。 FIG. 7 is a cross-sectional view taken along the line PP'of the water leakage detection sensor S, and FIG. 7A shows a state in which only the covering body B is disassembled. Further, in FIG. 7, the arrangement surface G is virtually shown by a straight line.
　図７に示すように、漏水検知シートＣのセンサ装置Ｄが設けられていない側の端部が、漏水検知シート支持部Ａ２ａに載置されることで、漏水検知シートＣが載置面Ａ１と略平行となるように、内部空間Ｒに収容される。 As shown in FIG. 7, the end portion of the water leakage detection sheet C on the side where the sensor device D is not provided is placed on the water leakage detection sheet support portion A2a, so that the water leakage detection sheet C becomes the mounting surface A1. It is housed in the internal space R so as to be substantially parallel.
　また、図７（ｂ）に示すように、載置体Ａ及び被覆体Ｂにより内部空間Ｒを形成した状態とすると、被覆体Ｂの脚部Ｂ２ａ、Ｂ４ａ及びＢ５ａの下端部が、それぞれ配置面Ｇに接触する。これにより、構造体本体１ａが全体的に安定した状態で配置面Ｇ上に配置される。
　また、折曲部Ｂ２、Ｂ３は、それぞれ折曲部Ａ３、Ａ４に面接触し、各ズレ防止部Ａ１ｃは、それぞれ折曲部Ｂ４、Ａ５に面接触した状態で、内部空間Ｒが形成される。 Further, as shown in FIG. 7B, assuming that the internal space R is formed by the mounting body A and the covering body B, the lower ends of the legs B2a, B4a, and B5a of the covering body B are arranged surfaces, respectively.

Further, the bent portions B2 and B3 are in surface contact with the bent portions A3 and A4, respectively, and the misalignment prevention portions A1c are in surface contact with the bent portions B4 and A5, respectively, to form an internal space R. ..
　図８は、漏水検知センサＳの使用例を示す概略斜視図である。
　本実施形態においては、実験動物Ｘとしてマウスが２匹飼育されているが、これに限られず、ラット、モルモット、ウサギ、イヌ等であっても良い。 FIG. 8 is a schematic perspective view showing a usage example of the water leakage detection sensor S.
In the present embodiment, two mice are bred as the experimental animal X, but the present invention is not limited to this, and may be rats, guinea pigs, rabbits, dogs and the like.
　図８に示すように、ケージＺは、上部が開口された略直方体状のケージ本体Ｚ１と、ケージ本体Ｚ１の開口を覆って設けられる網蓋部Ｚ２と、網蓋部Ｚ２上に配置される給水部Ｚ３と、ケージ本体Ｚ１の底面全体に敷設された木片からなる床材Ｚ４と、内部に餌やトイレ用の砂等飼育のための必要物が収容される飼育用物品収容部Ｚ５と、を有している。 As shown in FIG. 8, the cage Z is arranged on a substantially rectangular cage main body Z1 having an open upper portion, a net lid portion Z2 provided so as to cover the opening of the cage main body Z1, and a net lid portion Z2. A water supply unit Z3, a floor material Z4 made of a piece of wood laid on the entire bottom surface of the cage body Z1, and a breeding article storage unit Z5 in which necessary items for breeding such as food and sand for toilets are stored. have.
　給水部Ｚ３は、内部に水ｗが収容された給水部本体Ｚ３ａと、給水部本体Ｚ３ａから網蓋部Ｚ２を介してケージ本体Ｚ１内部に伸びる給水管Ｚ３ｂと、を含む。
　実験動物Ｘが、給水管Ｚ３ｂの先端部を突っつくことにより、給水部Ｚ３による給水が行われる。 The water supply unit Z3 includes a water supply unit main body Z3a in which water w is housed, and a water supply pipe Z3b extending from the water supply unit main body Z3a to the inside of the cage main body Z1 via the net lid portion Z2.
When the experimental animal X pokes the tip of the water supply pipe Z3b, water is supplied by the water supply unit Z3.
　漏水検知センサＳは、空間エンリッチメントＥが取付けられた状態で、ケージ本体Ｚ１の底面を配置面Ｇとして、ケージ本体Ｚ１に配置されている。
　ここで、漏水検知センサＳは、漏水検知の迅速性を向上させるため、配置部分の床材Ｚ４を除去し、載置面Ａ１が床材Ｚ４を介さず、直接配置面Ｇと対向するように配置されることが好ましい。 The water leakage detection sensor S is arranged on the cage body Z1 with the bottom surface of the cage body Z1 as the arrangement surface G in a state where the space enrichment E is attached.
Here, in order to improve the speed of water leakage detection, the water leakage detection sensor S removes the floor material Z4 of the arrangement portion so that the mounting surface A1 directly faces the arrangement surface G without passing through the floor material Z4. It is preferable to be arranged.
　上記のような状態となされたケージＺ内部において、実験動物Ｘが、給水管Ｚ３ｂの先端部を齧る、先端部に床材Ｚ４を詰める、といった行動をすることにより、給水管Ｚ３ｂから常時給水が行われ、漏水状態となる事態が生じた場合、水ｗがケージ本体Ｚ１の底面に広がっていき、次第に水位が上昇する。 Inside the cage Z in the above state, the experimental animal X bites the tip of the water supply pipe Z3b and fills the tip with the floor material Z4, so that water is constantly supplied from the water supply pipe Z3b. When this is done and a situation occurs in which a water leak occurs, the water w spreads to the bottom surface of the cage body Z1, and the water level gradually rises.
　そして、水位の上昇により、水ｗが、載置面Ａ１の漏水侵入孔Ａ１ａを通過し、内部空間Ｒに浸入する。 Then, due to the rise in the water level, the water w passes through the leak entry hole A1a of the mounting surface A1 and invades the internal space R.
　そして、さらなる水位の上昇により、水ｗが、漏水検知シートＣが配置されている高さまで到達した時点で、センサ装置Ｄが電極構成部Ｃ１を介して漏水を検知し、発信手段により、ＰＣ等の外部端末（図示せず）に検知結果を発信する。 Then, when the water w reaches the height at which the leak detection sheet C is arranged due to the further rise in the water level, the sensor device D detects the leak via the electrode component C1, and the transmission means means a PC or the like. The detection result is transmitted to the external terminal (not shown).
　これにより、管理者は、即座に漏水の発生を認識でき、給水部Ｚ３を回収する、といった措置を迅速に行うことが可能となる。 As a result, the manager can immediately recognize the occurrence of water leakage and can promptly take measures such as collecting the water supply unit Z3.
　本実施形態によれば、漏水検知センサ用構造体１を既存のケージＺに配置し、センサ２を載置体Ａ（内部空間Ｒ）に配置するのみで、確実に漏水の発生を検知することが可能となる。 According to the present embodiment, the occurrence of water leakage can be reliably detected only by arranging the structure 1 for the water leakage detection sensor in the existing cage Z and arranging the sensor 2 in the mounting body A (internal space R). Is possible.
　また、被覆体Ｂにより、センサ２を実験動物Ｘから保護し、実験動物Ｘのいたずら等によるセンサ２の不具合の発生を防止することが可能となる。 Further, the covering body B can protect the sensor 2 from the experimental animal X and prevent the sensor 2 from malfunctioning due to mischief of the experimental animal X or the like.
　また、載置体と前記被覆体とが、それぞれ別体に構成されていることで、センサ２の内部空間Ｒへの収容作業や、取り出し作業が容易となる。 Further, since the mounting body and the covering body are configured as separate bodies, the work of accommodating the sensor 2 in the internal space R and the work of taking it out can be facilitated.
　また、構造体本体１ａが、載置面Ａ１を、配置面Ｇから所定間隔離間させる間隔保持部Ａ１ｂを有することで、例えば、実験動物Ｘの尿により床材Ｚ４が濡れた場合に、誤ってセンサ２が検知、発信してしまう事態を防止し、漏水のみを確実に検知することが可能となる。 Further, since the structure main body 1a has an interval holding portion A1b that separates the mounting surface A1 from the arrangement surface G by a predetermined interval, for example, when the floor material Z4 is erroneously wetted by the urine of the experimental animal X, for example, It is possible to prevent the situation where the sensor 2 detects and transmits, and to reliably detect only water leakage.
　また、構造体本体１ａが、空間エンリッチメントＥを取付け可能な、空間エンリッチメント取付け部Ｂ１ｂを有することで、センサ２による漏水の検知を行いつつ、構造体本体１ａをケージＺ内の環境に適応させ、実験動物Ｘのストレスを軽減させることが可能となる。 Further, since the structure body 1a has the space enrichment mounting portion B1b to which the space enrichment E can be mounted, the structure body 1a is adapted to the environment inside the cage Z while detecting water leakage by the sensor 2. It is possible to reduce the stress of the experimental animal X.
　また、被覆体Ｂが、センサ装置Ｄが露出可能な露出孔Ｂ１ａを有することで、構造体本体１ａがセンサの発信を阻害することなく、露出孔Ｂ１ａを介して、センサ２によるスムーズな外部機器への発信を行うことが可能となる。 Further, since the covering body B has the exposed hole B1a that the sensor device D can expose, the structure main body 1a does not interfere with the transmission of the sensor, and the sensor 2 allows a smooth external device through the exposed hole B1a. It becomes possible to make a call to.
　また、載置体Ａは、漏水検知シートＣを、載置面Ａ１から所定間隔離間して支持する、漏水検知シート支持部Ａ２ａを含むことで、漏水検知シートＣが載置面Ａ１に面接触することを防止することができ、例えば、実験動物Ｘの尿により床材Ｚ４が濡れた場合に、誤ってセンサ２が検知、発信してしまう事態を防止し、漏水のみを確実に検知することが可能となる。 Further, the mounting body A includes a water leakage detection sheet support portion A2a that supports the water leakage detection sheet C at a predetermined interval from the mounting surface A1, so that the water leakage detection sheet C comes into surface contact with the mounting surface A1. For example, when the floor material Z4 gets wet with the urine of the experimental animal X, it is possible to prevent the sensor 2 from accidentally detecting and transmitting the information, and to reliably detect only water leakage. Is possible.
　以下、図９及び図１０を用いて、本発明の他の実施形態に係る漏水検知センサ用構造体及びそれを備えた漏水検知センサについて説明する。 Hereinafter, with reference to FIGS. 9 and 10, a structure for a water leakage detection sensor according to another embodiment of the present invention and a water leakage detection sensor provided with the structure will be described.
　図９に示すように、漏水検知センサ用構造体１は、構造体本体１ａをケージＺの内部に吊り下げ可能な吊り下げ部１ｂを備えていても良い。 As shown in FIG. 9, the structure 1 for a water leakage detection sensor may include a hanging portion 1b capable of suspending the structure main body 1a inside the cage Z.
　詳述すれば、吊り下げ部１ｂは、構造体本体１ａに一対設けられており、帯状体を輪状にして形成された吊り下げ部本体１ｂ１と、構造体本体１ａの吊り下げ長さを調節可能な調節部１ｂ２と、吊り下げ部本体１ｂ１の端部に設けられた引っ掛け部１ｂ３と、を有している。 More specifically, a pair of hanging portions 1b are provided on the structure main body 1a, and the hanging portion main body 1b1 formed by forming a band-shaped body in a ring shape and the hanging length of the structure main body 1a can be adjusted. It has an adjusting portion 1b2 and a hooking portion 1b3 provided at an end portion of the hanging portion main body 1b1.
　各吊り下げ部本体１ｂ１は、３つの貫通孔Ａ３ａの内の両端の貫通孔Ａ３ａに、それぞれ挿通されている。
　各調節部１ｂ２は、本実施形態では所謂バックルであるが、面ファスナーを用いた調節構造等を採用しても良く、特に限定されない。 Each hanging portion main body 1b1 is inserted into through holes A3a at both ends of the three through holes A3a.
Each adjusting portion 1b2 is a so-called buckle in the present embodiment, but an adjusting structure using a hook-and-loop fastener or the like may be adopted, and the present invention is not particularly limited.
　図１０に示すように、吊り下げ部１ｂにより、各引っ掛け部１ｂ３をケージ本体Ｚ１の開口端に引っ掛けることで、漏水検知センサＳ全体を、ケージＺの内部に吊り下げた状態で配置することが可能となる。
　漏水検知センサＳをこのような配置とする場合、ケージＺの側面が配置面Ｇとなる。 As shown in FIG. 10, by hooking each hooking portion 1b3 to the open end of the cage main body Z1 by the hanging portion 1b, the entire water leakage detection sensor S can be arranged in a suspended state inside the cage Z. It will be possible.
When the water leakage detection sensor S is arranged in this way, the side surface of the cage Z is the arrangement surface G.
　なお、漏水検知センサＳをこのような配置とする場合、被覆体Ｂの載置体Ａからの脱離を防止するために、構造体本体１ａの外周面に、脱離防止部材Ｔを圧着して設けておくことが好ましい。脱離防止部材Ｔとしては、例えば輪ゴムや任意の紐状体、帯状体等が好適に用いられる。
　また、漏水検知の迅速性を向上させるために、各吊り下げ部本体１ｂ１の長さは、調節部１ｂ２により、構造体本体１ａの下端（本実施形態においては折曲部Ａ４）とケージＺの底面とが接触するか、若しくは極力近接する長さに調節されていることが好ましい。 When the water leakage detection sensor S is arranged in this way, the detachment prevention member T is crimped to the outer peripheral surface of the structure main body 1a in order to prevent the covering body B from detaching from the mounting body A. It is preferable to provide the above. As the detachment prevention member T, for example, a rubber band, an arbitrary string-shaped body, a band-shaped body, or the like is preferably used.
Further, in order to improve the speed of water leakage detection, the length of each hanging portion main body 1b1 is adjusted by the adjusting portion 1b2 to the lower end of the structure main body 1a (bent portion A4 in this embodiment) and the cage Z. It is preferable that the length is adjusted so that it comes into contact with the bottom surface or is as close as possible to the bottom surface.
　本実施形態によれば、構造体本体１ａをケージＺの内部に吊り下げ可能な吊り下げ部１ｂを備えることで、構造体本体１ａがケージＺの底面の一定面積を占有しないため、センサ２による漏水の検知を行いつつ、ケージＺの底面をより広く活用することができる。これにより、飼育に必要な所望の物品を配置する等、柔軟にケージＺ内部の環境を変更することが可能となる。 According to the present embodiment, since the structure main body 1a is provided with the hanging portion 1b capable of suspending the structure main body 1a inside the cage Z, the structure main body 1a does not occupy a certain area on the bottom surface of the cage Z, so that the sensor 2 is used. The bottom surface of the cage Z can be used more widely while detecting water leakage. This makes it possible to flexibly change the environment inside the cage Z, such as arranging desired articles necessary for breeding.
　また、吊り下げ部１ｂが、その吊り下げ長さを調節可能な調節部１ｂ２を有することで、ケージＺの大きさに合わせて、構造体本体１ａのケージＺの底面からの距離を調節し、漏水検知の迅速性を向上させることが可能となる。 Further, since the hanging portion 1b has an adjusting portion 1b2 whose hanging length can be adjusted, the distance of the structure main body 1a from the bottom surface of the cage Z can be adjusted according to the size of the cage Z. It is possible to improve the speed of water leakage detection.
　なお、上述の各実施形態において示した各構成部材の諸形状や寸法等は一例であって、設計要求等に基づき種々変更可能である。 Note that the various shapes and dimensions of each component shown in each of the above-described embodiments are examples, and can be variously changed based on design requirements and the like.
　例えば、図１１に示すように、漏水侵入孔Ａ１ａ及び露出孔Ｂ１ａを覆うように、載置面Ａ１及び被覆面Ｂ１それぞれに、漏水侵入孔用板状体ＰＡ及び露出孔用板状体ＰＢを設ける構成としても良い。漏水侵入孔用板状体ＰＡ及び露出孔用板状体ＰＢは、例えばポリプロピレン等の耐熱性を有する合成樹脂により形成される。また、漏水侵入孔用板状体ＰＡ及び露出孔用板状体ＰＢは、例えば任意の接着剤を介して、載置面Ａ１及び被覆面Ｂ１に固定しておくことが好ましい。
　なお、図１１（ａ）は、漏水検知センサ用構造体１の概略斜視図であり、露出孔用板状体ＰＢは点線で示している。また、図１１（ｂ）は、載置体Ａの平面図である。 For example, as shown in FIG. 11, a plate-shaped body PA for a water leakage entry hole and a plate-shaped body PB for an exposed hole are provided on each of the mounting surface A1 and the covering surface B1 so as to cover the water leakage entry hole A1a and the exposed hole B1a. It may be provided as a configuration. The plate-shaped body PA for the water leakage entry hole and the plate-shaped body PB for the exposed hole are formed of a synthetic resin having heat resistance such as polypropylene. Further, it is preferable that the plate-shaped body PA for the water leakage entry hole and the plate-shaped body PB for the exposed hole are fixed to the mounting surface A1 and the covering surface B1 via, for example, an arbitrary adhesive.
Note that FIG. 11A is a schematic perspective view of the water leakage detection sensor structure 1, and the exposed hole plate-shaped body PB is shown by a dotted line. Further, FIG. 11B is a plan view of the mounting body A.
　このようにすることで、漏水侵入孔Ａ１ａや露出孔Ｂ１ａを介して、例えば実験動物Ｘの尿が入り込み、センサ装置Ｄが誤ってセンサ情報を発信してしまう事態を防止することが可能となる。 By doing so, it is possible to prevent a situation in which, for example, the urine of the experimental animal X enters through the water leakage entry hole A1a and the exposed hole B1a, and the sensor device D erroneously transmits the sensor information. ..
　また、図１１（ｂ）に示すように、漏水侵入孔用板状体ＰＡには、複数の切り欠き部ＰＡ１が形成されており、各切り欠き部ＰＡ１を介して複数の漏水侵入孔Ａ１ａが部分的に露出するように構成されている。 Further, as shown in FIG. 11B, a plurality of notch portions PA1 are formed in the plate-shaped body PA for the water leakage intrusion hole, and the plurality of water leakage intrusion holes A1a are formed through the notch portions PA1. It is configured to be partially exposed.
　このようにすることで、センサ装置Ｄと外部機器との間の通信障害を起こりにくくすることが可能となる。
　なお、本実施形態では、露出孔用板状体ＰＢが露出孔Ｂ１ａを全面的に覆っている例を示しているが、露出孔用板状体ＰＢに、露出孔Ｂ１ａを部分的に露出させるための切り欠き部を設ける構成としても良い。 By doing so, it is possible to reduce the occurrence of communication failure between the sensor device D and the external device.
Although the present embodiment shows an example in which the exposed hole plate-shaped body PB completely covers the exposed hole B1a, the exposed hole B1a is partially exposed on the exposed hole plate-shaped body PB. It may be configured to provide a notch for the purpose.
