Description
本発明は、円筒型の磁石本体の下方に、プローブを出し入れする空間を持って設置される強磁場磁石装置に関し、特にNMR用に広く用いられている超伝導コイルを有する強磁場を発生する装置に関する。 The present invention relates to a strong magnetic field magnet device installed below a cylindrical magnet body with a space for inserting and removing a probe, and in particular, a device for generating a strong magnetic field having a superconducting coil widely used for NMR. About.
この種、強磁場磁石装置は、円筒型の本体下方のプローブを出し入れする空間を持って設置されており、磁場は、本体の縦軸(Z軸)中心に発生し、図3、図4に示すように漏れ磁場が絶えず存在している。
このため、磁場による周辺の磁性体が本体下面に最も良く吸引される。
特に超伝導コイルを有するものでは、その吸引力が強く、長時間の専門的な操作によって磁力を弱めない限り、吸着されたものを取り除くことは不可能であった。
このような不測の吸着を防止するために観音式の扉を持った箱形の防護壁を設けることを試みたが、開口部を開いたときに、日常的には存在しない位置に扉が存在することとなり、誤って扉に衝突するなどの危険を再生することなった。
また、扉の開閉のために周囲に空間を保持しなければならず、周辺機器との関係からこのような防護壁の設置は困難であった。
This kind of strong magnetic field magnet device is installed with a space for taking in and out the probe under the cylindrical main body, and the magnetic field is generated at the center of the vertical axis (Z axis) of the main body. As shown, a stray magnetic field is constantly present.
For this reason, the surrounding magnetic body by a magnetic field is best attracted | sucked by the main body lower surface.
In particular, in the case of having a superconducting coil, the attracting force is strong, and it is impossible to remove the adsorbed material unless the magnetic force is weakened by a long-time professional operation.
In order to prevent such accidental adsorption, we tried to provide a box-shaped protective wall with a kannon-type door, but when the opening was opened, there was a door in a position that does not exist on a daily basis. It was to regenerate the danger of accidentally colliding with the door.
In addition, it is necessary to maintain a space around the door for opening and closing the door, and it is difficult to install such a protective wall because of the relationship with peripheral devices.
本発明このような実情に鑑み、強磁場磁石装置の設置位置周辺に余分な空間を必要とせず、また解放時にも周辺に異物が特出するようなことのない防護壁を提供することを目的とする。 In view of such circumstances, an object of the present invention is to provide a protective wall that does not require an extra space around the installation position of the strong magnetic field magnet device and that does not cause any foreign matter to protrude around when it is released. And
本発明1の強磁場磁石装置は、その円筒型本体と接地面との間の空間周辺に、前記本体と同心状の円弧状で、非磁性体よりなる防護壁が設けてあり、その防護壁の一側面の開放部分を開口部とし、前記防護壁の外周に沿って、これと同心の円弧状の非磁性体よりなる扉が、その弧状中心周りに移動自在にして設けられていて、当該扉により前記開口部を開閉自在に閉止してあることを特徴とする構成を採用した。
本発明2の強磁場磁石装置は、前記発明1において、前記扉の下端を支える基板は、設置状態で、前記磁石本体を支える脚注を入れ込む空間を内側に有する円環状となる複数の弧状片よりなることを特徴とする構成を採用した。
The strong magnetic field magnet apparatus according to the first aspect of the present invention is provided with a protective wall made of a non-magnetic material in the shape of a circular arc concentric with the main body around the space between the cylindrical main body and the ground surface. An open portion on one side of the protective wall is provided as an opening, and a concentric arc-shaped non-magnetic door is provided along the outer periphery of the protective wall so as to be movable around the arc-shaped center. A configuration is employed in which the opening is closed by a door so as to be freely opened and closed.
A strong magnetic field magnet apparatus according to a second aspect of the present invention is the magnetic field magnet device according to the first aspect, wherein the base plate supporting the lower end of the door is in an installed state and has a plurality of arcuate pieces having an annular shape with a space for inserting a footnote supporting the magnet body inside. The structure characterized by comprising is adopted.
本発明1は、上記構成により、円弧状の扉は円筒状の本体の周囲あるいはその最外周の内側を通って、移動することにより、防護壁の開口部を開閉することができた。
その結果、本体への不測な物品の吸着を未然に防止することができるのみならず、プローブの出し入れに際し、扉を開閉しても周辺に、扉が本体外方に突出して、非日常的な場所に扉が位置することによる危険を再生することが無くなった。
また、本体周囲に扉開閉の為に空間を確保することもないので周辺機器の設置スペースをこのような防護壁を設けていない状態と何ら変わりなく確保することが出来た。
また、本発明2は、上記構成により、防護壁なして、既に設置されている強磁場磁石装置に対しても、これらの設置を移動することなく発明1の防護壁及び扉などを追加設置することができた。
According to the first aspect of the present invention, the arcuate door can be opened and closed by moving the arcuate door through the periphery of the cylindrical main body or the inside of the outermost periphery thereof.
As a result, it is possible not only to prevent accidental adsorption of articles to the main body, but also when opening and closing the probe, even if the door is opened and closed, the door protrudes outward from the main body. The dangers caused by the location of the door in the place no longer regenerate.
In addition, since there is no space around the body for opening and closing the door, the space for installing peripheral devices can be secured as if there were no such protective walls.
Further, the present invention 2 additionally installs the protective wall and the door of the first invention without moving these installations even with respect to the already installed strong magnetic field magnet device without the protective wall by the above configuration. I was able to.
