Description

【０００１】
【発明の属する技術分野】
本発明は、育舎開口部の開閉装置に関し、特に停電時には自動的に開口部を開き、給電時には開口部を自動的に閉める育舎開口部の開閉装置に関する。
【０００２】
【従来の技術】
家畜類を飼育する畜舎や鶏類を飼育する養鶏場等、あるいは園芸植物を育てる育舎（以下、これらを総称して育舎という）においては、育舎内の温度、湿度、照明、給餌等を集中管理している。また、この種の育舎では、通常の換気は専用の換気ダクト及び換気ファンで強制的に行っている。しかしながら、停電時には上記換気ダクト及び換気ファンによる換気機能の停止により換気機能、温度管理機能、湿度管理機能が停止してしまう。換気機能、温度管理機能、湿度管理機能が停止すると、育舎内はほぼ密閉されているために、換気不良や酸欠状態により、家畜等の死亡、衰弱事故や園芸植物等が弱るという不測の事故が発生する。
【０００３】
そこで、上記のような不都合を回避するため、例えば特開平７−２８９１０４号公報において、下記構成になるものが提案されている。以下、この従来例に係る育舎開口部の開閉装置を、添付図面を参照して説明する。図４は育舎の正面図、図５は育舎の開口部の開閉装置の概要図である。
【０００４】
この従来例に係る育舎開口部の開閉装置は、図５に示すように、育舎１の側壁に開けられた開口部２を開閉する開閉自在なカーテン状の開閉部材である昇降帆布２０を備えている。この昇降帆布２０の上端は吊持ワイヤ２１により吊持されており、この吊持ワイヤ２１の先端は、滑車２３を介して矢印ａ方向の垂直方向から斜め方向に変向されて矢印ｂ方向の横方向に往復移動する駆動ワイヤ２４に連結されている。この駆動ワイヤ２４は、滑車２５により上下方向に方向変換されて、駆動モータ３０により減速機２９を介して駆動される電動ウインチ２６のドラムにより巻取り、巻戻されるように構成されている。
【０００５】
一方、上記昇降帆布２０の下端は、一端側にドラム３２を備えた巻芯２２により巻取り、巻戻されるように構成されており、このドラム３２に巻回されてなるワイヤが上記電動ウインチ２６により回転されるドラム３１に巻回されている。つまり、電動ウインチ２６のドラムにより駆動ワイヤ２４が巻取られて、吊持ワイヤ２１を介して昇降帆布２０が上昇されると、この昇降帆布２０の下端が巻戻されるとともに、電動ウインチ２６のドラムから駆動ワイヤ２４が巻戻されて、吊持ワイヤ２１を介して昇降帆布２０が下降されると、この昇降帆布２０の下端が巻取られるように構成されている。なお、符号２７は電動ウインチ２６の逆転防止手段であり、また符号２８は逆転防止解除手段である。
【０００６】
【発明が解決しようとする課題】
上記従来例に係る育舎開口部の開閉装置によれば、停電時に自動的に昇降帆布２０が下降して育舎１の開口部２が開く。従って、育舎１内の換気不良や酸欠状態による家畜等の死亡、衰弱事故や園芸植物等が弱るというような不測の事故を未然に防止することができるが、以下のような不具合がある。
【０００７】
ａ．開口部２を合成樹脂繊維で織った昇降帆布２０の昇降により開口部２を開閉する構成であるため、断熱性が低く、気密性も低いので、育舎１内の温度管理、湿度管理に不都合を来す。
ｂ．昇降帆布２０を備えた開閉装置が電動ウインチを必要とする等、開閉装置の構成が複雑で、高価である。
ｃ．また、吊持ワイヤ２１の伸びや切断の他に、この吊持ワイヤ２１の取り替えや長さ調整に手間取り、メインテナンスが容易でないという問題もある。
【０００８】
従って、本発明の目的は、停電時における換気不良や酸欠状態により、家畜等の死亡、衰弱事故や園芸植物等が弱るという不測の事故を未然に防止することができ、開口部の断熱性や気密性に優れ、かつ構成が簡単で、電動ウインチや駆動ワイヤ等を必要とせず、安価でメインテナンスが容易な開口部の開閉装置を提供することである。
【０００９】
【課題を解決するための手段】
本発明の育舎開口部の開閉装置は、上記課題を解決するために、下記のように構成したものである。
即ち、請求項１に記載の発明は、停電時には自重により育舎１の側壁に設けられた開口部２を開くとともに、給電時には上記開口部２を閉める開閉自在な開閉部材１０を備えた育舎開口部の開閉装置において、上記開閉部材１０を、上下に複数重ねられ、空気流通路を介して相互に空気が流通する複数の横長の空気袋１３から構成し、これら複数の空気袋１３のうちの一つに給排気口１４を設け、この給排気口１４に給排気ダクト１６を連通させるとともに、この給排気ダクト１６先端に送風機１７を望ませたことを特徴とする。
【００１０】
請求項２に記載の発明は、請求項１に記載の育舎開口部の開閉装置において、上記開閉部材１０は、表裏の合成樹脂からなるシート材１１の端部を溶着し、かつ複数の平行な直線に沿ってそれぞれ間欠的に溶着するとともに、平行な直線同士の間で上記空気袋１３が形成され、また間欠的な溶着部間に上記空気流通路が形成されるように構成されてなることを特徴とする。
【００１１】
請求項３に記載の発明は、請求項１または２のうちの何れかに記載の育舎開口部の開閉装置において、上記開閉部材１０の空気袋１３は、相互に圧接されて上記開口部２を閉めるように構成されてなることを特徴とする。
【００１２】
請求項４に記載の発明は、請求項１または２のうちの何れかに記載の育舎開口部の開閉装置において、上記空気袋１３の非膨張時における上記開閉部材１０の上下方向の寸法Ｌは、上記開口部２の上下方向の寸法Ｄの１．７〜２．２倍に設定されてなることを特徴とする。
【００１３】
【発明の実施の形態】
以下、本発明の実施の形態に係る育舎開口部の開閉装置を添付図面に基づいて説明する。図１（Ａ）は育舎開口部の開閉装置の概要図、図１（Ｂ）は開閉部材が閉まっている状態を示す縦断面図、図１（Ｃ）は開閉部材が開いている状態を示す縦断面図、図２は開閉部材を構成するシート材の平面図、図３は無拘束状態で膨らませた開閉部材の縦断面図である。
【００１４】
本実施の形態に係る育舎開口部の開閉装置は、図１（Ａ）に示すように、育舎１の側壁に設けられた開口部２を開閉する開閉部材１０を備えている。この開閉部材１０は、図２に示すように、上辺で二つ折りにした合成樹脂からなるシート材１１を溶着することにより構成されている。より詳しくは、表裏の合成樹脂からなるシート材１１の端部を溶着し、かつ複数の平行な直線に沿ってそれぞれ間欠的に溶着する。これにより、間欠的な溶着部１２を有する平行な直線同士の間で空気袋１３が形成され、また間欠的な溶着部１２同士の間に空気流通路が形成されることとなる。上記空気袋１３は上下５段に形成されており、これら空気袋１３が膨らんだ状態では、図３に示すように、縦断面が略円形の空気袋１３が溶着部１２を介して連なっている。
【００１５】
上記構成になる開閉部材１０の上部コーナ部には給排気口１４が形成されており、この給排気口１４に口金１５が取付けられている。この口金１５には、弾性変形可能な給排気ダクト１６の一端側が接続されるとともに、この給排気ダクト１６の他端側に、４０〜６０Ｗの消費電力が小さい送風機（この送風機はシロッコファンである）１７が望ませてある。なお、上記開閉部材１０の上部コーナ部に、給排気口１４を設けたのは、停電時における開閉部材１０の自重による収縮、下降させて育舎１の開口部２を円滑に開き、また給電時における空気袋１３の膨らみにより育舎１の開口部２を円滑に閉めるためである。
【００１６】
また、上記給排気ダクト１６の他端側に送風機１７を望ませたのは、給電中における送風機からの空気の送給により、開閉部材１０の空気袋１３が過剰圧で破損しないように、かつ停電時に開閉部材１０の空気袋１３内の空気が円滑に排気されるように意図したものである。なお、図１において、送風機１７を囲っているものは機枠１８であり、また送風機１７と給排気ダクト１６とを覆ってなるものはカバー１９である。
【００１７】
上記育舎１の開口部２は、図１（Ａ）乃至図１（Ｃ）に示すように、開口枠６によって区画されている。この開口枠６は、上下一対の横桟５に固定されており、これら各横桟５は所定の間隔で立設されてなる支柱３により支持されている。上記一対の横桟５の間には、育舎１の内側から上記開閉部材１０を支える亀甲金網４が張設されるとともに、上記支柱３の対向位置に、上記開口枠６に固着されてなるガイドロッド７が配されており、育舎１の外側から上記開閉部材１０を支えるように構成されている。
【００１８】
上記開閉部材１０の空気袋１３を膨らませた状態では、図１（Ｂ）に示すように、上下の隣接する空気袋１３同士が相互に圧接して、育舎１の開口部２を閉めるようになっている。この場合、開閉部材１０の溶着部１２が育舎１の内外方向に交互に変形することにより、空気袋１３が圧接している。これにより、育舎１の開口部２の断熱性や気密性が格段に向上することとなる。
【００１９】
因みに、本実施の形態においては、上記開閉部材１０の空気袋１３の直径は約１５０ｍｍに設定されており、この空気袋１３から空気が抜けた、非膨張時における開閉部材１０の上下方向の寸法Ｌは、上記育舎１の開口部２の上下方向の開口寸法Ｄの１．７〜２．２倍に設定されている。また、空気袋１３が膨らんだ状態における開閉部材１０の上下方向の寸法Ｌ１は、上記育舎１の開口部２の上下方向の開口寸法Ｄの１．７〜２．２倍に設定され、上記育舎１の開口部２の上下方向の開口寸法Ｄの略１．２５倍に設定されている。これにより、空気袋１３が育舎１の内外方向に交互にずれて相互に圧接するため、育舎１の開口部２を効果的に閉めて、育舎１内の断熱性や気密性を格段向上させることが可能になる。
【００２０】
以下、上記構成の本実施の形態に係る育舎開口部の開閉装置の使用態様を説明する。即ち、給電時には、送風機１７により給排気口１４、給排気ダクト１６を介して空気を送給して開閉部材１０の各空気袋１３を膨らませる。これにより、上記育舎１の開口部２が閉められるため、育舎１内の断熱性や気密性が確保される。一方、停電時には、上記送風機１７が停止し、自重により空気袋１３内の空気が給排気口１４、給排気ダクト１６を介して排気されて空気袋１３が萎むので、上記育舎１の開口部２が開く。従って、換気不良や酸欠状態により、家畜等の死亡、衰弱事故や園芸植物等が弱るという不測の事故が未然に防止される。
【００２１】
本実施の形態に係る育舎開口部の開閉装置によれば、従来例のように、開口部２を合成樹脂繊維で織った昇降帆布で閉める構成でなく、断熱性が優れた空気により膨らんだ空気袋１３の圧接により開口部２を閉める構成であるため、断熱性が優れ、気密性も優れているので、従来例のように育舎１内の温度管理、湿度管理に不都合を来すようなことがない。また、従来例のように電動ウインチを必要とせず、送風機だけであるから、従来例よりも開閉装置の構成が簡単で、設備費も廉価である。さらに、従来例のように吊持ワイヤ２１を用いる構成でなく、それらの交換や長さ調整作業が不要であるから、送風機１７をメインテナンスすれば足りるから、メインテナンスも極めて簡単である。
【００２２】
上記実施の形態では、開閉部材１０が上下に５段の空気袋１３を備えている場合の例を説明したが、開口部２の大きさや育舎１の側壁の厚さに応じて適宜変更することができる。また、上記実施の形態では、開閉部材１０が表裏のシート材１１を溶着して構成されている場合の例を説明したが、接着剤等により接着しても差し支えない。なお、上記開閉部材１０を構成するシート材としては、家畜用にあっては遮光性を有するものが用いられる一方、園芸植物用にあっては透光性のものが用いられる。
【００２３】
また、上記実施の形態では、開閉部材１０の空気袋１３に空気が入っていない非膨張時における上下方向の寸法Ｌを育舎１の開口部２の上下方向の開口寸法Ｄの１．７〜２．２倍に設定した場合を例として説明したが、この点についても開口部の大きさや側壁の厚さに応じて適宜変更することができる。
【００２４】
【発明の効果】
以上述べたように、請求項１に記載の発明では、従来例のように、開口部２を合成樹脂繊維で織った昇降帆布で閉める構成でなく、断熱性が優れた空気により膨らんだ空気袋１３の圧接により開口部２を閉める構成であるため、断熱性が優れ、気密性も優れているので、従来例のように育舎１内の温度管理、湿度管理に不都合を来すようなことがない。また、従来例のように電動ウインチを必要とせず、送風機だけであるから、従来例よりも開閉装置の構成が簡単で、設備費も廉価である。さらに、従来例のように吊持ワイヤ２１を用いる構成でなく、それらの交換や長さ調整作業が不要であるから、送風機１７をメインテナンスすれば足りるから、メインテナンスも極めて簡単である。
【００２５】
請求項２に記載の発明では、開閉部材（１０）は、表裏の合成樹脂からなるシート材１１を溶着した構成であるから、構成が簡単で、しかも安価である。
【００２６】
請求項３に記載の発明では、開閉部材１０の空気袋１３は、相互に圧接されて開口部２を閉めるように構成されていて、開口部２の断熱性、気密性に優れているので、育舎１内の温度管理、湿度管理が容易に行える。
【００２７】
請求項４に記載の発明では、空気袋１３の非膨張時における上記開閉部材１０の上下方向の寸法Ｌは、開口部２の上下方向の寸法Ｄの１．７〜２．２倍に設定されていて、空気袋１３が膨らむと、空気袋１３同士が相互に圧接するので、開口部２の断熱性、気密性を向上させることができる。

[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the opening and closing device for a nursery building opening according to an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 (A) is a schematic diagram of an opening / closing device for a nursery building opening, FIG. 1 (B) is a longitudinal sectional view showing a state in which the opening / closing member is closed, and FIG. 1 (C) is a state in which the opening / closing member is open. 2 is a plan view of a sheet material constituting the opening / closing member, and FIG. 3 is a longitudinal sectional view of the opening / closing member inflated in an unconstrained state.
[0014]
As shown in FIG. 1A, the opening / closing device for the nursery opening according to the present embodiment includes an opening / closing member 10 that opens and closes the opening 2 provided on the side wall of the nursery 1. As shown in FIG. 2, the opening / closing member 10 is configured by welding a sheet material 11 made of synthetic resin that is folded in half on the upper side. In more detail, the edge part of the sheet | seat material 11 which consists of a synthetic resin of front and back is welded, and it welds intermittently along several parallel straight lines, respectively. Thereby, the air bag 13 is formed between the parallel straight lines which have the intermittent welding part 12, and an air flow path will be formed between the intermittent welding parts 12. FIG. The air bags 13 are formed in five upper and lower stages, and when the air bags 13 are inflated, the air bags 13 having a substantially circular longitudinal section are connected via the welded portion 12 as shown in FIG. .
[0015]
An air supply / exhaust port 14 is formed in the upper corner portion of the opening / closing member 10 having the above-described configuration, and a base 15 is attached to the air supply / exhaust port 14. One end of an elastically deformable air supply / exhaust duct 16 is connected to the base 15 and a blower with low power consumption of 40 to 60 W is connected to the other end of the air supply / exhaust duct 16 (this fan is a sirocco fan). ) 17 is desired. The reason why the air supply / exhaust port 14 is provided in the upper corner of the opening / closing member 10 is that the opening 2 of the building 1 is opened smoothly by contracting and lowering due to the weight of the opening / closing member 10 during a power failure. This is because the opening 2 of the nursery building 1 is smoothly closed by the swelling of the air bag 13 at the time.
[0016]
In addition, the fan 17 is desired on the other end side of the air supply / exhaust duct 16 so that the air bag 13 of the opening / closing member 10 is not damaged by excessive pressure by supplying air from the fan during power feeding, and This is intended to smoothly exhaust the air in the air bag 13 of the opening / closing member 10 at the time of a power failure. In FIG. 1, a frame 18 surrounds the blower 17, and a cover 19 covers the blower 17 and the air supply / exhaust duct 16.
[0017]
As shown in FIGS. 1A to 1C, the opening 2 of the breeding house 1 is partitioned by an opening frame 6 . The opening frame 6 is fixed to a pair of upper and lower horizontal bars 5, and each of the horizontal bars 5 is supported by a column 3 erected at a predetermined interval. Between the pair of horizontal bars 5, a turtle shell metal net 4 that supports the opening and closing member 10 is stretched from the inside of the building 1, and is fixed to the opening frame 6 at a position facing the support column 3. A guide rod 7 is arranged, and is configured to support the opening / closing member 10 from the outside of the building 1.
[0018]
In the state where the air bag 13 of the opening / closing member 10 is inflated, as shown in FIG. 1 (B), the upper and lower adjacent air bags 13 are pressed against each other so as to close the opening 2 of the building 1. It has become. In this case, the air bag 13 is press-contacted by the welding part 12 of the opening / closing member 10 being alternately deformed in the inside and outside directions of the building 1. Thereby, the heat insulation and airtightness of the opening part 2 of the building 1 will be improved significantly.
[0019]
Incidentally, in the present embodiment, the diameter of the air bag 13 of the opening / closing member 10 is set to about 150 mm, and the vertical dimension of the opening / closing member 10 at the time of non-inflation when the air has escaped from the air bag 13. L is set to 1.7 to 2.2 times the opening dimension D in the vertical direction of the opening 2 of the breeding house 1. Further, the vertical dimension L1 of the opening / closing member 10 in a state where the air bag 13 is inflated is set to 1.7 to 2.2 times the vertical dimension D of the opening 2 of the breeding house 1, It is set to approximately 1.25 times the opening dimension D in the vertical direction of the opening 2 of the nursery building 1. As a result, since the air bags 13 are alternately displaced in the inner and outer directions of the building 1 and are pressed against each other, the opening 2 of the building 1 is effectively closed, and the heat insulating property and the airtightness in the building 1 are remarkably improved. It becomes possible to improve.
[0020]
Hereinafter, the usage aspect of the opening / closing apparatus of the nursery opening part which concerns on this Embodiment of the said structure is demonstrated. That is, at the time of power feeding, air is supplied by the blower 17 through the air supply / exhaust port 14 and the air supply / exhaust duct 16 to inflate each air bag 13 of the opening / closing member 10. Thereby, since the opening part 2 of the said building 1 is closed, the heat insulation and airtightness in the building 1 are ensured. On the other hand, at the time of power failure, the ventilator 17 is stopped, the air supply and exhaust port 14 in the air bag 13 by its own weight, since the supply and exhaust duct 16 is exhausted through the air bladder 13 is deflated, opening of the Ikusha 1 Part 2 opens. Therefore, unforeseen accidents such as death of livestock, debilitating accidents, and horticultural plants becoming weak due to poor ventilation or lack of oxygen can be prevented.
[0021]
According to the opening / closing device for the building opening according to the present embodiment, as in the conventional example, the opening 2 is not configured to be closed by a lifting canvas woven with synthetic resin fibers, but is swelled by air having excellent heat insulating properties. Since the opening 2 is closed by the pressure contact of the air bag 13, the heat insulation and the airtightness are excellent, so that the temperature management and humidity management in the building 1 are inconvenient as in the conventional example. There is nothing. Further, unlike the conventional example, the electric winch is not required and only the blower is used. Therefore, the configuration of the switchgear is simpler and the equipment cost is lower than the conventional example. Furthermore, since it is not the structure which uses the suspension wire 21 like a prior art example, and replacement | exchange and length adjustment work are unnecessary, since it is sufficient to maintain the air blower 17, maintenance is also very simple.
[0022]

【The invention's effect】
As described above, the invention according to claim 1 is not a configuration in which the opening 2 is closed with a lifting canvas woven with synthetic resin fibers as in the conventional example, but an air bag inflated with air having excellent heat insulation properties. Since the structure is such that the opening 2 is closed by the pressure contact 13, the heat insulation is excellent and the air tightness is excellent, so that the temperature management and humidity management in the nursery 1 are inconvenient as in the conventional example. There is no. Further, unlike the conventional example, the electric winch is not required and only the blower is used. Therefore, the configuration of the switchgear is simpler and the equipment cost is lower than the conventional example. Furthermore, since it is not the structure which uses the suspension wire 21 like a prior art example, and replacement | exchange and length adjustment work are unnecessary, since it is sufficient to maintain the air blower 17, maintenance is also very simple.
[0025]
In the invention according to claim 2, since the opening / closing member (10) has a structure in which the sheet material 11 made of synthetic resin on the front and back sides is welded, the structure is simple and inexpensive.
[0026]
In the invention according to claim 3, the air bag 13 of the opening / closing member 10 is configured to be pressed against each other and close the opening 2, and is excellent in heat insulation and airtightness of the opening 2. Temperature management and humidity management in the nursery 1 can be easily performed.
[0027]
In the invention according to claim 4, the vertical dimension L of the opening / closing member 10 when the air bag 13 is not inflated is set to 1.7 to 2.2 times the vertical dimension D of the opening 2. In addition, when the air bag 13 is inflated, the air bags 13 are pressed against each other, so that the heat insulating property and the air tightness of the opening 2 can be improved.
