【発明の詳細な説明】
この発明は複数枚の単位反射鏡パネルで構成されるアン
テナ反射鏡の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an antenna reflector comprised of a plurality of unit reflector panels.
この種アンテナ反射鏡を地面に対し水平に近い角度で設
置または回転を停止した場合、単位反射鏡パネルの周辺
部では雨が降り止んだ後も表面張力の影響により、かな
り広範囲に雨水が残る。When this type of antenna reflector is installed at an angle close to horizontal to the ground or its rotation is stopped, rainwater remains over a fairly wide area around the unit reflector panel even after the rain has stopped due to surface tension.
この雨水の存在はアンテナの電気特性を著しく劣化させ
る。The presence of this rainwater significantly deteriorates the electrical characteristics of the antenna.
この発明はこのような点にかんがみてなされたもので、
アンテナ反射鏡を地面に対し水平に近い角度で設置また
は回転を停止しても、単位反射鏡パネルの周辺部に雨水
が残らない電気持性の良好なアンテナ反射鏡を提供する
ものである。This invention was made in view of these points,
To provide an antenna reflector with good electricity retention, in which rainwater does not remain on the periphery of a unit reflector panel even when the antenna reflector is installed at an angle close to horizontal to the ground or its rotation is stopped.
以下第１図に示すこの発明の実施例について説明する。An embodiment of the invention shown in FIG. 1 will be described below.
図はアンテナ反射鏡２の曲面の一部で１ａ〜１ｄは所定
間隔ｄ１例えば３ｍｍ程度の間隔ｄをあけて配設され上
記曲面の一部を形成する単位反射鏡パネル，３ａ，３ｂ
はアルミ板等の金属板をＬ字形に折曲げ形成された一対
のガイド板で単位反射鏡パネル１ｃの周辺部に第２図に
示される如く所定間隔、例えば１．５ｍｍ程度あけ相対
向して設けられ、単位反射鏡パネル１ｃの鏡面と直角に
交差するスリット４を形成している。The figure shows a part of the curved surface of the antenna reflector 2, and 1a to 1d are unit reflector panels 3a and 3b that are arranged at a predetermined interval d1, for example, about 3 mm, and form a part of the curved surface.
are a pair of guide plates formed by bending a metal plate such as an aluminum plate into an L shape, and are placed facing each other at a predetermined interval, for example, about 1.5 mm, around the periphery of the unit reflector panel 1c, as shown in FIG. A slit 4 is provided and intersects the mirror surface of the unit reflecting mirror panel 1c at right angles.
なお上記ガイド板３ａ，３ｂの端部は第３図に示される
ように単位反射鏡パネル１ｃの鏡面上に突出し、かつ鏡
面と接触している。As shown in FIG. 3, the ends of the guide plates 3a and 3b protrude above the mirror surface of the unit reflecting mirror panel 1c and are in contact with the mirror surface.
５は単位反射鏡パネルを補強する補強材、６はガイド板
３ａ，３ｂを補強材５に固定するねじである。5 is a reinforcing member for reinforcing the unit reflecting mirror panel, and 6 is a screw for fixing the guide plates 3a, 3b to the reinforcing member 5.
このような構成におけるアンテナ反射鏡２を地面に対し
て水平に近い角度で設置または回転を停止した場合、ア
ンテナ反射鏡２の曲面の最低部となるＡ部に残った雨水
は手細管現象によってスリット４に吸い込まれる。When the antenna reflector 2 in such a configuration is installed at an angle close to horizontal to the ground or stops rotating, the rainwater remaining at the lowest part of the curved surface of the antenna reflector 2, A, will flow through the slits due to the canal phenomenon. It gets sucked into 4.
単位反射鏡パネル１ｃの周辺部を越した雨水は自重のた
めにスリット４を降下して行き、ガイド板３ａ，３ｂの
端まで達したところで水滴となって落下する。Rainwater that has passed over the periphery of the unit reflector panel 1c descends through the slit 4 due to its own weight, and when it reaches the ends of the guide plates 3a, 3b, it becomes water droplets and falls.
このような過程の繰返しによって単位反射鏡パネル鏡面
上の周辺部に残ろうとする雨水は全て除去される。By repeating this process, all the rainwater that remains on the mirror surface of the unit reflecting mirror panel is removed.
第４図はこの発明の他の実施例で第１図と異なるところ
は単位反射鏡パネル１ｃの鏡面とほゞ平行の面を有する
アルミ板等の金属板で形成されたガイド板７と上記鏡面
とによってスリット４を形成した点でその作用は上述同
様であるので説明を省略する。FIG. 4 shows another embodiment of the present invention, which differs from FIG. 1 in that it includes a guide plate 7 formed of a metal plate such as an aluminum plate having a surface substantially parallel to the mirror surface of the unit reflector panel 1c, and the mirror surface. Since the operation is the same as described above in that the slit 4 is formed by the above, the explanation will be omitted.
なお以上はガイド板をアルミ板からなる金属板で形成し
たものについて述べたが、これには限らずステンレス板
を用いても良く、また電波の透過性の良好な非金属部材
、例えばＦＲＰ．（ＦｉｂｅｒｇｌａｓｓＲｅｉｎｆｏ
ｒｃｃｄ Ｐｌａｓｔｉｃｓ）を用いても良いし、さ
らにガイド板はねじによって補強材に取付けることなく
例えば溶接あるいは接着剤等を使用しても良い、さらに
スリットは単位反射鏡パネルの周辺部の１ケ所のみなら
ず複数個所に設けてもよいし一枚以上の単位反射鏡パネ
ルのそれぞれに設けても良くまた、スリットは単位反射
鏡の鏡面と直角に交差することなく、それ以下の角度で
交差しても良く、その作用は上述同様故説明を省略する
。Although the guide plate has been described above as a metal plate made of an aluminum plate, it is not limited to this, and a stainless steel plate may also be used, and a non-metallic member with good radio wave transmittance, such as FRP. (Fiberglass Reinfo
rcd Plastics) may be used, or the guide plate may be welded or adhesive, for example, without being attached to the reinforcing material with screws.Furthermore, if the slit is only at one location on the periphery of the unit reflector panel, the guide plate may be attached to the reinforcement material using screws. The slits may be provided at multiple locations, or may be provided on each of one or more unit reflecting mirror panels, and the slits may not intersect the mirror surface of the unit reflecting mirror at right angles, but may also intersect at an angle less than that. The operation is the same as described above, so the explanation will be omitted.
さらにまた第５図に示す如く単位反射鏡パネルの周辺部
を切欠きスリット４を形成し、このスリットの相対向す
る面部を単位反射鏡パネル１の鏡面側に突出８させても
上述同様の作用効果が得られる。Furthermore, as shown in FIG. 5, a slit 4 is formed by cutting out the periphery of the unit reflector panel, and the opposing surfaces of the slit protrude 8 toward the mirror surface side of the unit reflector panel 1. Effects can be obtained.
以上のようにこの発明によれば、アンテナ反射鏡の鏡面
上の雨水は自動的に除去されるので、雨水によるアンテ
ナ性能の劣化が従来のものに比し著しく軽減され、常に
良好なアンテナ性能が得られる等効果がある。As described above, according to the present invention, rainwater on the mirror surface of the antenna reflector is automatically removed, so deterioration of antenna performance due to rainwater is significantly reduced compared to conventional systems, and good antenna performance is always maintained. There are effects such as those obtained.
