【産業上の利用分野】本発明は、警報装置に関し、特に
送電線鉄塔などの高電圧危険箇所に取り付けられる送電
線鉄塔用警報装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm device, and more particularly to an alarm device for a power transmission line tower which is attached to a high voltage dangerous place such as a power line tower.
【０００２】[0002]
【従来の技術】送電線鉄塔の送電線には約６万ボルト〜
１００万ボルトもの高電圧が印加されており、その線路
は多回線、かつ大型化されている。このような送電線鉄
塔の建設において、最近の地価高騰の影響で都市郊外の
鉄塔用地の買収が極めて困難となったため険しい山奥に
建設される傾向にある。2. Description of the Related Art About 60,000 V
A high voltage of 1 million volts is applied, and the line is multi-line and large. In the construction of such transmission line towers, the recent rise in land prices has made it extremely difficult to purchase land for tower towers in the suburbs of the city, so there is a tendency for them to be built deep in the mountains.
【０００３】そのため送電線の建設を行う電工は、例え
ば建設現場まで行くのに数時間歩き、目的地に到達して
から数十キログラムもの工具を身に付け、百数十メート
ルもの高い鉄塔に塔上して架線作業（補修作業）を行う
という重労働の状態である。Therefore, an electrician who constructs a power transmission line, for example, walks for several hours to reach a construction site, wears tens of kilograms of tools after reaching a destination, and builds a tower in a tower as high as hundreds of tens of meters. It is a state of heavy labor in which the overhead wire work (repair work) is performed.
【０００４】ところでこの架線作業前に必ず行うＴ，
Ｂ，Ｍ（Tool Box Meeting）やＫＹＴ（危険予知訓練）
は、既に一般に普及しており、実行されているにもかか
わらず、電工が誤って充電部に近寄り感電死することが
少なくない。By the way, T, which must be performed before the overhead line work,
B, M (Tool Box Meeting) and KYT (danger prediction training)
Although it has already been widely used and is being executed, it is not uncommon for electricians to accidentally approach the charging section and suffer electric shock.
【０００５】その原因はいろいろ推測されるが、慣れに
よる勘違い、疲労による打ち合わせ内容の度忘れ、地上
の専任監視員からの警告の不徹底によるものと推測され
る。Various causes are conjectured, but it is presumed to be due to misunderstanding due to getting used to it, forgetting the details of the meeting due to fatigue, and inadequate warning given by a dedicated observer on the ground.
【０００６】ここで図３は一方が停電状態で、他方が充
電状態の送電線鉄塔に電工が昇る状態を示す図である。Here, FIG. 3 is a diagram showing a state in which the electric work rises to a transmission line tower in which one is in a power failure state and the other is in a charging state.
【０００７】たとえば図３において、送電線鉄塔１の１
Ｌ側の送電線２が停電状態、２Ｌ側の送電線３が充電状
態であるとする。電工４が鉄塔１の昇降柱１ａを利用し
て２Ｌ側から昇り、２Ｌ側のアーム１ｂに到達した時１
Ｌ側のアーム１ｃに横移動すべきところを、錯誤により
２Ｌ側のアーム１ｂの先に近寄り感電死する場合が考え
られる。また鉄塔１内で作業を続けているとどちらが１
Ｌか２Ｌかを見失う場合も考えられるが、いずれにせ
よ、送電線２、３を見ても電気が充電されているか停電
なのか外観では見分けがつかない。[0007] For example, in FIG.
It is assumed that the L-side power transmission line 2 is in a power failure state and the 2L-side power transmission line 3 is in a charging state. When the electrician 4 climbs from the 2L side by using the elevating column 1a of the steel tower 1 and reaches the arm 1b on the 2L side 1
It is conceivable that a place where the arm 1c on the L side should be moved laterally may approach the tip of the arm 1b on the 2L side and be electrocuted due to an error. Which is 1 if you continue to work inside the tower 1.
It may be possible to lose sight of whether it is L or 2L, but in any case, even if the transmission lines 2 and 3 are seen, it is impossible to distinguish from the appearance whether electricity is being charged or a power failure.
【０００８】そこで電工４に図示しない検電器を持たせ
て送電線２、３に電気が充電されているか停電なのかを
判別することが提案されている。この検電器は電磁誘導
を利用して送電線から発生する磁気を検出するようにな
っている。Therefore, it has been proposed to provide an electric detector (not shown) to the electrician 4 to determine whether the transmission lines 2 and 3 are charged with electricity or a power failure. This voltage detector uses electromagnetic induction to detect magnetism generated from a power transmission line.
【０００９】[0009]
【発明が解決しようとする課題】しかしながら、電圧が
高くなると鉄塔１内はどこでも磁気が強くなり、充電
部、停止路線に関係なく検電器が作動してしまうので判
別できなくなる。However, when the voltage becomes high, the magnetism becomes strong everywhere inside the tower 1, and the electroscope operates regardless of the charging section or the stop line, so that it cannot be determined.
【００１０】そこで、本発明の目的は、上記課題を解決
し、送電線鉄塔などの高電圧危険箇所において電磁誘導
の影響を受けることなく充電部に作業者等が接近すると
警報を発する送電線鉄塔用警報装置を提供することにあ
る。Therefore, an object of the present invention is to solve the above-mentioned problems and to issue an alarm when a worker or the like approaches a charging part without being affected by electromagnetic induction in a high voltage dangerous place such as a transmission line tower. It is to provide an alarm device for use.

A detector, an alarm that generates an alarm sound when the detector operates, and a power source including a solar battery that supplies power to the alarm and the detector, and a storage battery that is connected in parallel with the solar battery and stores power. It is a thing.

圧による磁気の影響を受けないので装置が誤動作せず、
感知器が作業者等の接近を感知すると警報器が作動して
作業者等に高圧危険箇所の存在を知らせるので作業の安
全性が向上し、電源が太陽電池及び蓄電池からなるため
電池の交換が略不要となる。According to the above construction, since the container attached to the high voltage dangerous place is electromagnetically shielded, it is not affected by magnetism due to the high voltage of the power transmission line, so that the device does not malfunction.
When the sensor detects the approach of workers, etc., the alarm activates to notify the workers, etc. of the presence of high-voltage hazardous areas, improving work safety.Because the power source consists of solar cells and storage batteries, batteries need to be replaced. It is almost unnecessary.
