Description

【０００１】
【発明の属する技術分野】
この発明は、内圧自動検出装置を備えた空気式防舷材に係わり、更に詳しくは中空丸型の空気式防舷材に取付けられるエアー給排バルブに、内圧検出送信装置または内圧検出送信装置及び起動スイッチを設けた内圧自動検出装置を備えた空気式防舷材に関するものである。
【０００２】
【従来の技術】
従来、岸壁に係留されている空気式防舷材には、中空円筒形状（俵状）に形成された所謂丸型防舷材や、円筒の上下面に鋼板鉄板を内蔵したフランジ部を有する所謂セル型防舷材が知られている。
前記丸型防舷材１は、例えば、図７及び図８に示すように、中空円筒形状の防舷材本体１ａを横方向から圧縮して使用するタイプで、岸壁Ｇ等への取付けは、チェーン２を防舷材本体１ａの中に挿通し、そのチェーン２の両端を岸壁Ｇに固定するものである。
【０００３】
また防舷材本体１ａの長手方向の両端に設けたフィッティング金具または口金部３の一方には、図示しないエアー給排バルブが設けられている。
また、セル型防舷材は、円筒状の防舷材本体の一端側に設けた固定フランジをアンカーボルト及びテンションチェーン，シェアーチェーンを介して岸壁に固定し、円筒状の防舷材本体の他端側の取付フランジには、前衝板及びパッドが取付けられ、防舷材本体の長手方向（円筒の高さ方向）に圧縮して使用するタイプで、与えられる荷重の方向に対して方向性がないことから、複雑な荷重が作用する浮体の係留用ばねとしても多く使用されている。
【０００４】
ところで、岸壁に設置されている空気式防舷材は、その緩衝機能を十分に発揮出来るように、空気圧が設定圧を維持しているか、また防舷材本体に異常がないかを定期的に検査する、所謂、空気式防舷材の管理が必要となっている。
上記のような空気式防舷材の定期的な点検作業としては、岸壁に設置された空気式防舷材に対しては、ボート等を利用して岸壁に設置された空気式防舷材の位置まで行き、圧力の測定を一々行っているが、海上の状態によっては常に安全であるとは限らず、海が荒れているような場合には、ボートが揺れて圧力点検作業が極めて危険な場合がある。
【０００５】
また、空気式防舷材のエアーの注入，排出バルブは、一般に小さいため、注入，排出バルブに圧力ゲージホルダーを接続するのが難く、ボート等からの作業では作業時間がかかると言う問題があった。
更に、海上に設置された空気式防舷材が、例えば、接触事故やバルブ故障等によりエアー漏れを起こしているような場合であっても、設置されている場所に測定にいかないと、エアー漏れを発見することができない場合があり、事前に徐々にエアーが抜けて行く状態をモニター出来ないと言う問題があった。
【０００６】
そこで、上記のような空気式防舷材の内圧を自動的に検出する方法としては、従来から種々の発明（特開昭62-194313 号公報) や、考案（実願昭56-94860公報のマイクロフィルム, 実開昭58-1623 号公報、実願昭58-87082号のマイクロフィルム, 実開昭59-192922 号公報、実願昭59-196185 号のマイクロフィルム, 実開昭61-112243 号公報) が提案されているが、いずれも空気式防舷材の設置場所に行って測定するものであり、空気式防舷材から離れた位置で定期的に内圧を検査したり、事前に測定作業を行うことは出来なかった。
【０００７】
更に、従来の内圧を自動的に検出する装置は、防舷材本体１ａに設けたエアー給排バルブの取付け場所とは別の位置に、個別に設計したものを使用するため、フィティング金具等の設計を変更する必要があり、従って、フィティング金具に設ける取付けネジ部に既設のエアー給排バルブをそのまま使用することが出来ず、またエアー給排バルブを簡単に交換することが出来ないと言う問題があった。
【０００８】
更に、従来の内圧自動検出装置は、海上に設置された空気式防舷材と共に長期間に渡って設置され、内圧自動検出装置を起動して防舷材本体内の圧力を検出するのは、定期的または必要に応じて測定するため、電源を常に入れた状態にしておくと、電源が短期間に消耗してしまいうと言う問題があった。
【０００９】
【発明が解決しようとする課題】
この発明は、かかる従来の課題に着目して案出されたもので、特に中空丸型の防舷材本体に取付けられている既存のエアー給排バルブに、内圧自動検出装置を一体的に設けることで、従来のフィティング金具等の設計を変更する必要がなくなり、経済的であると共に、組付け作業や、保守点検等に便利な内圧自動検出装置を備えた空気式防舷材を提供することを目的とするものである。
【００１０】
また、この発明の他の目的は、内圧自動検出装置に起動スイッチを設けて、必要に応じて内圧自動検出装置を起動させて内圧を測定するので、電源の消耗を防止して電源の寿命を伸ばすことが出来る内圧自動検出装置を備えた空気式防舷材を提供することを目的とするものである。
【００１１】
【課題を解決するための手段】
この発明は上記目的を達成するため、エアー給排バルブの先端に、防舷材本体内の圧力を検出する内圧検出センサー，制御機器，送信部及び電源から成る内圧検出送信装置を設けたことを要旨とするものである。
また、この発明はエアー給排バルブに、防舷材本体内の圧力を検出する内圧検出センサー，制御機器，送信部及び電源から成る内圧検出送信装置を設け、前記エアー給排バルブの頭部に、前記内圧検出送信装置の起動スイッチを設けたことを要旨とするものである。
【００１２】
前記起動スイッチが、光学的スイッチ，電磁式スイッチ，導電ゴムを使用したスイッチ等を使用するものである。
この発明は上記のように構成され、既存のエアー給排バルブに、内圧自動検出装置を一体的に設けることで、既存のフィティング金具に形成されている規格された取付けネジ部にエアー給排バルブと共に、内圧自動検出装置を簡単に取付けることが出来、また既存の防舷材本体に取付けられているエアー給排バルブに変えて内圧自動検出装置を備えたエアー給排バルブを簡単に交換することが出来るものである。
【００１３】
また、エアー給排バルブの頭部に、前記内圧検出送信装置の起動スイッチを設けたので、内圧検出送信装置を必要に応じて起動スイッチの光学スイッチ，電磁式スイッチ，導電ゴム等により起動させることが出来、この結果電源の無駄な消耗を防止でき、寿命を伸ばすことが出来るものである。

BACKGROUND OF THE INVENTION
The present invention relates to a pneumatic fender having an internal pressure automatic detection device, and more particularly, to an air supply / discharge valve attached to a hollow round pneumatic fender, an internal pressure detection transmission device or an internal pressure detection transmission device, and The present invention relates to a pneumatic fender having an internal pressure automatic detection device provided with a start switch.
[0002]
[Prior art]
Conventionally, pneumatic fenders moored on a quay include a so-called round fender formed in a hollow cylindrical shape (a bowl shape), or a so-called flange portion having a steel plate incorporated in the upper and lower surfaces of a cylinder. Cell type fenders are known.
The round fender 1 is, for example, a type in which a hollow cylindrical fender main body 1a is compressed from the lateral direction as shown in FIGS. 7 and 8, and attached to a quay G or the like. The chain 2 is inserted into the fender main body 1a, and both ends of the chain 2 are fixed to the quay G.
[0003]
Further, an air supply / discharge valve (not shown) is provided on one of the fittings provided at both ends in the longitudinal direction of the fender main body 1a or the base part 3.
In addition, the cell-type fender has a fixed flange provided on one end of the cylindrical fender main body, fixed to the quay via anchor bolts, tension chains, and shear chains. The front flange and pad are attached to the mounting flange on the end side, and it is used by compressing it in the longitudinal direction (cylinder height direction) of the fender body. Directionality with respect to the applied load direction Therefore, it is often used as a mooring spring for a floating body to which a complicated load is applied.
[0004]
By the way, the pneumatic fenders installed on the quay regularly check whether the air pressure is maintained at the set pressure and that there are no abnormalities in the fender body so that the buffer function can be fully exerted. It is necessary to manage so-called pneumatic fenders to be inspected.
As a regular inspection work of the pneumatic fenders as described above, for pneumatic fenders installed on the quay, a pneumatic fender installed on the quay using a boat etc. I go to the position and measure the pressure one by one, but it is not always safe depending on the sea condition, and when the sea is rough, the boat shakes and the pressure check work is extremely dangerous There is a case.
[0005]
In addition, since the air injection and discharge valves of pneumatic fenders are generally small, it is difficult to connect a pressure gauge holder to the injection and discharge valves, and there is a problem that it takes time to work from a boat or the like. It was.
Furthermore, even if a pneumatic fender installed on the sea causes air leakage due to, for example, a contact accident or a valve failure, There was a case where the leak could not be detected, and there was a problem that it was not possible to monitor the state in which the air gradually escaped in advance.
[0006]
Therefore, as a method for automatically detecting the internal pressure of the pneumatic fender as described above, various inventions (Japanese Patent Laid-Open No. 62-194313) and devices (Japanese Patent Application No. 56-94860) have been proposed. Microfilm, Japanese Utility Model Publication No. 58-1623, Japanese Utility Model Publication No.58-87082, Japanese Utility Model Publication No.59-192922, Japanese Utility Model Publication No.59-196185 Microfilm, Japanese Utility Model Publication No.61-112243 However, in all cases, measurements are taken at the place where the pneumatic fender is installed, and the internal pressure is periodically inspected at a position away from the pneumatic fender, or measured in advance. I couldn't do the work.
[0007]
Furthermore, since the conventional device for automatically detecting the internal pressure uses an individually designed device at a position different from the mounting position of the air supply / discharge valve provided on the fender body 1a, fitting fittings, etc. Therefore, the existing air supply / discharge valve cannot be used as it is for the mounting screw part provided on the fitting, and the air supply / discharge valve cannot be easily replaced. There was a problem to say.
[0008]
Furthermore, the conventional internal pressure automatic detection device is installed over a long period of time with a pneumatic fender installed on the sea, and the internal pressure automatic detection device is activated to detect the pressure in the fender main body. There is a problem that if the power is always turned on to measure periodically or as necessary, the power will be consumed in a short time.
[0009]
[Problems to be solved by the invention]
The present invention has been devised by paying attention to such a conventional problem, and in particular, an internal air pressure automatic detection device is integrally provided in an existing air supply / discharge valve attached to a hollow round fender body. This eliminates the need to change the design of conventional fittings and the like, and provides a pneumatic fender equipped with an internal pressure automatic detection device that is economical and convenient for assembly work, maintenance and inspection. It is for the purpose.
[0010]
Another object of the present invention is to provide a start switch for the internal pressure automatic detection device and start the internal pressure automatic detection device as needed to measure the internal pressure. An object of the present invention is to provide a pneumatic fender having an automatic internal pressure detecting device that can be extended.
[0011]
[Means for Solving the Problems]
Since this invention to achieve the above object, the tip of the air supply and discharge valves, provided pressure detection sensor for detecting the pressure fender body, control devices, the pressure detection transmission system comprising transmitting unit and power supply or al This is the gist.
Further, according to the present invention, the air supply / discharge valve is provided with an internal pressure detection / transmission device including an internal pressure detection sensor for detecting the pressure in the fender body, a control device, a transmission unit, and a power source. The gist of the invention is that a startup switch for the internal pressure detection / transmission apparatus is provided.
[0012]
The start switch uses an optical switch, an electromagnetic switch, a switch using conductive rubber, or the like.
The present invention is configured as described above, and an internal air pressure automatic detection device is integrally provided on an existing air supply / discharge valve, so that an air supply / discharge is performed on a standard mounting screw portion formed on an existing fitting. Along with the valve, the internal pressure automatic detection device can be easily installed, and the air supply / discharge valve equipped with the internal pressure automatic detection device can be easily replaced by replacing the air supply / discharge valve attached to the existing fender body. It can be done.
[0013]
In addition, since the start switch of the internal pressure detection / transmission device is provided on the head of the air supply / discharge valve, the internal pressure detection / transmission device can be activated by an optical switch, electromagnetic switch, conductive rubber, etc., as necessary. As a result, wasteful consumption of the power source can be prevented and the life can be extended.
