【0001】〔産業上の利用分野〕この発明は架空送電線を打撃の衝撃によって除雪する除雪装置に関するものである。
【0002】〔従来の技術〕従来の架空送電線の融雪および落氷雪対策としては、電線の通電電流により発生する磁界を利用し融雪線材に発生する鉄損により発熱して電線を暖め着雪を防止する融雪線材、雪の回転を防止して着雪防止を図る方法として一定間隔にリングを取り付けるリング方式、電線の上を除雪して回る電線の除雪ロボット、電線に巻き付けられた螺旋状の除雪部の両端に風車を取り付け風の力で除雪するもの、PTFT難着雪テープを送電線に巻き付けることで雪の付着力を弱める方法、その他難着性の塗料の開発等があった。
【0003】〔発明が解決しようとする課題〕以上のような融雪および落氷雪対策もそれぞれ機能して役立ってはいるが、急激な大雪や湿った雪とか温度の問題などで単独で完璧に排雪に成功しているものでは無く、複数重畳的に使用しても尚且つ対処しきれない場合も多い。
【0004】そのような場合、現場における実際の対処は、作業員が鉄塔に登りハンマーやバットなどで電線に衝撃を与え排氷雪している。その際に多額の経費が掛かるのは勿論だが、通常鉄塔には高圧電流が流れているため、作業の際には安全のため一時送電をストップしなければならず、電力会社にとっては金銭問題以上の懸案事項になっている。
【0005】架空送電線に対する着氷雪は、架空送電線の弛みを起こさせ断線事故や電線が垂れ下がり地面に接地しショートする危険、更には電線に掛かる重力が鉄塔を傾けたり倒すといったような危険をもたらし、見過ごすことの出来ない自然災害であるので以上述べてきたことを解決するのが課題である。
【0006】〔課題を解決するための手段〕以上のような現状から、本発明は実際上最終手段とされてきた、作業員が鉄塔に登り架空電線に対して打撃の衝撃により行ってきた排氷雪を、シンプルな装置の作業に置き換え、手動又は自動で駆動を行うことによって除雪することにより、高圧電流を切ることもなく、高所作業に伴う危険の除去、経費の節減などを実現し、最も現実的な架空送電線の除雪解決の手段とする。
【0007】〔作用〕本発明は、いずれも架空送電線に降り積もった氷雪を除雪装置のハンマー部(3)の打撃による衝撃で落雪させようというものであるので、電動式にあっては手動又は自動で除雪装置にスイッチが入ると、装置のバーの先端のハンマー部が送電線に打撃を加え、その衝撃により送電線の排雪を行う。
【0008】請求項1、2、3は原節部のカム(7、9)をギヤードモーターで駆動し、一端をベースに結合された湾曲したバー(2)の中程の従節部(5、10)を持ち上げる。その際、バーは引っ張りバネ(6)でベースに固定されているのでバネが伸びバーは引きつけられているので、カムの最高点を過ぎた途端バーをベース方向に引きつけ、その衝撃でハンマー部が送電線に打撃を加える。バネ(6)は押しバネを兼ね、打撃の瞬間以外にハンマーが送電線に常時接するのを妨げる働きもする。(図1)は、ピン付きカムによりバーが押し上げられバネが伸びている所。(図2)は、通常のカムの頂点が通り過ぎ、バーが引きつけられてハンマーが送電線に打撃を与えている所。(図3)は、請求項3のダブルバー、ダブルカム式で、左向きのバーは送電線に打撃を加え、右向きのバーはカムによって押し上げられている所。
【0009】請求項4、、6はギヤードモーターの駆動による回転運動をクランク軸(16)と連接節(17)でテコであるバーを左右又は上下運動に変換して送電線に打撃を加える。(図4、6)請求項5、7は、ハンマー付きのバーの回転部に設置した正逆回転するギヤードモーターがハンマー部に設けたスイッチが打撃の衝撃で切り替わり回転方向が変わることにより駆動する。(図5、7)バーのの回転軸に取り付けられたモーターの回転方向が切り替われば、バーの方向が切り替わる。モーターの回転方向が一定でもクランク軸と連接節でテコであるバーの押し引き運動に変換すれば同様の運動になるのは当然の事である。
【0010】請求項8は、駆動原理に電磁コイル(22)と永久磁石(23)を利用し、コイルの電極をスイッチにより切り換える事により、磁気の吸引、反発が生じ同様の運動が起こることにより作動する。(図8)
【0011】請求項9、10は、電気を使用しない重力の差で作動するもので、何れも雪受け板(25)に雪が降り積もり、雪の重量が他方のハンマー部(3)又は重り(26)より重くなった時にバーの中央部を支点に下に下がり、溜まった雪を排雪して軽くなる。その後、請求項9にあっては持ち上げられたハンマー部が自重で下に落ち送電線に衝撃をあたえる。(図9)は排雪してハンマーが打ちつけた所。請求項10にあってはハンマー部と雪受け板に積もった雪の重量が、重りの重量を越えると、バーの回転部を支点に重りが上がり、下に下がった雪受け板付きハンマー部は排雪を行い軽くなりハンマー部は上に上がり送電線(19)に打ちつけられる。以上による衝撃で送電線の排雪を行う。(図10)
【0012】請求項11は降雪センサーと電子基板の判断で必要な時だけに除雪装置を作動させる方法である。降雪センサーに付いては湿度と温度で作動するものなどいろいろ開発されているが、本発明における請求項9、10の雪受け板付きバーを小型化し雪が積ると作動する点を生かせば降雪センサーとして利用する事もできる。必要な時だけ作動するので省エネ効果は高い。
【0013】請求項12に付いては、除雪装置の簡略化と電気代の節約の為に、雪が有っても無くても一日数回数秒づつタイマーで電気を送り装置を作動させるものである。雪が無いときに作動しても別段の問題もなく、タイマーは安価で普及しているので、装置全体の価格の引き下げに役立つ。
【0014】〔実施例〕本発明の除雪装置は、現場の雪の性質によっては単純な打撃で完全に排雪出来ない場合もあるので、垂直方向の打撃に加えて水平方向の打撃も加えるという必要もある。その場合は、本発明の除雪装置を組み合わせて使用すれば解決する。バーに付いては、図面上は板状だがパイプでも良い。
【0015】請求項1、2の違いはカム部の従節部と原節部の形式の違いである。又、請求項3に付いては鉄塔に取り付ける際に、一般に送電線は切れ間無く左右に延びていて、当然雪は左右の電線にも積るので請求項1、2の除雪装置を個別に配置しても問題は解決するが、全体として一台でしかもギヤードモータも一台で作動させたほうが経済的であるため考案したものである。請求項1にあっては半月状の従節部を持つ二本のハンマー付きのバーをそれぞれ左右対象に配置し(半月状の従節部にあってはモーターの回転方向が同じであるため対象ではなく同じ向きである。)、タイミング時機を反対にした原節部である円盤にピン(8)を打ち込んだ形式のカムをそれぞれのバーに取り付け、同軸上のギヤードモーターで回転させる。請求項2に付いても通常の形式のカムを使用しているだけで同様である。タイミング時機を反対にしたのは、同時にバーを持ち上げる事がないようにすれば、ギヤードモーターの力を二倍にする必要がない為であり、そのような事を考慮しなければタイミングが同じでも良い。又、カムのピンを複数にして位置を変えたり、カム自体の形状を工夫すれば大きな打撃と小さな打撃を組み合わせてトンタタ、トンタタというように打撃のリズムをかえる事もできる。
【0016】本発明の除雪機は、架空送電線が鉄塔の腕鉄に配置されている為に高所にコンパクトに設置しなければならないが。請求項4に付いては、鉄骨または付け足したベースに支持される一本の支承体(15)で設置ができる。
送電線は鉄塔の上の方に走っており、碍子の取り付け方や電線の配置も現場によりマチマチである。本発明の送電線の除雪装置も鉄塔の鉄骨乃至は設置の為に付け加えた鉄骨にコンパクトに取り付けなくてはならないが、打撃の方向とかハンマー部の形態は現場の必要性に応じて斜めや下からであったり、長くしたり曲げたりと柔軟に対処しなくてはならない。電動式にあっては方向を選ばない。
【0017】請求項5に付いては、正逆回転するギヤードモーターで駆動する点で請求項4とちがう。請求項4、5は下から交互に打撃を加える形式であるのに対し、請求項6、7は反対方向から同時に打撃を加えると言う点で違いがある。
【0018】請求項6、7は送電線に対し中央の軸(31)を回転部(32)が回転し主に水平方向方面から打撃を加える際の除雪機であるが垂直方向でもよい。図5に示した様に、複数の送電線に対応するために複数のバーをリンク機構として連結し、一個の動力源で同時に排雪することもできる。この場合、ハンマー部(30)が上下に長ければ、上下に配置されている送電線に同時に対応出来る。この際のハンマー部は下の送電線に届く様充分に長い物である。又、直線状のバー(21)は直線でなくエス状でもゼット状の形態のバーでも効果は同じである。
【0019】請求項8に付いては、除雪装置の作動動力に永久磁石(23)と電磁コイル(22)の電極を切り換える事によって発生する磁石の吸引、反発を利用したもので以上述べてきたと同様の運動をさせることが出来るものである。
【0020】請求項9は、送電線の上に設置する場合のもので特に作動用の電源が無い場合に降り積もった雪の重量という自然のエネルギーで作動させる為のものであり送電線の上側に設置する形式である。同様の原理で請求項10は送電線の下側に設置するものである。
【0021】請求項11、12に付いては、本発明送電線の除雪装置は何時も動かしておく必要は無く、むしろ雪が電線に絡みつき自然落下しない場合のみ作動するのが望ましいが、降雪センサーやタイマーでできるだけ短時間自動運転出来る用にしたものである。
【0022】除雪装置を作動させる適当な電源が鉄塔に無い場合、鉄塔に風車や太陽電池を設置して常時バッテリーに蓄え、必要なときに電源とする事も出来る。又、何れにしても、パトロールで現場の職員が車で巡回して回るということもあるので、車のバッテリーに装置を繋いで作動させる事もできる。その場合は、電線を鉄塔の下まで配線しておけば鉄塔に上がる事もなく、センサーもタイマーも必要なく現地の状況に応じ手動でスイッチを入れたり、切ったり出来る。
【0023】ハンマー部に関しては、送電線が風や雪の重みで振れたり、垂れ下がったりする事もあるので、多少幅を広くする必要がある。又、通常送電線は平行に複数本、多段に張られているので、電線をまたぐ長いバー状のハンマー部(28、図11)とした場合、平行に走る送電線を除雪装置一台で一度に排雪する事もできる。さらに、多段の送電線に対応するために、上述の長いバーを多段(29、図11)に配置すれば、多段の送電線の排雪も一度でできる。
【0024】ハンマーそのものに関しては、送電線に強すぎる衝撃を与えるのを防ぐ為に押しバネで浮かして取り付ける事もできる。スイッチも兼ねる場合は浮いているのが打撃の際にバネが収縮し接触するする事を利用できるので一石二鳥の効果がある。バネ付きハンマー部(30)。
【0025】本発明は、送電線の除雪に向けたものであるが、通常鉄塔の送電線は高圧なので、装置を取り付ける際ベースやハンマー部などの絶縁には特に気を付けなくてはならない。ハンマー部などはゴム等の絶縁物質(34)でライニングすると当たり具合も絶縁にもよい。また同時に電線の打撃を受ける部分にも広めに同様な材質の電線被覆保護材(13)で補強する事が必要である。
【0026】電気式の駆動に付いては、本発明はすべてギヤードモーター(7)としたが、これは現在小型で低回転でトルクも高く強力で価格も安いという既成品が多数出回っており、本発明のコンパクトでシンプルで安くという目的に合致するからである。通常の高速モーターでプーリーとファンベルトとか遊星ギャ等の様々な減速装置を用いても効果にかわりはない。
【0027】〔発明の効果〕本発明は以上述べてきた様に、鉄塔に張られた架空送電線の除雪装置に関するものである。過去大メーカーや電力会社で様々な取り組みと開発が行われてきたが、それぞれに効果があってもそれだけで完璧というものは無く、最後は、鉄塔の電流を切り作業員が鉄塔に登るという危険をおかしながら送電線に打撃による衝撃を与え排雪してきたのである。本発明は、その最後の作業さえシンプルな除雪装置で機械化してしまおうというものである。よって、作業員の危険回避、作業経費の削減、送電線の一時中断を回避するということ等の多くの利点がある。
【0028】送電線に対する打撃の衝撃による排氷雪は実際に現在まで手作業で行われてきた実績があり、その効果については実証済である。本発明は、その作業をシンプルな除雪装置に置き換え機械化したもので実行性は高い。

Field of the Invention The present invention relates to a snow removing device for removing snow from an overhead transmission line by the impact of a blow.
2. Description of the Related Art Conventionally, as a countermeasure against snow melting and falling ice on an overhead power transmission line, a magnetic field generated by an electric current flowing through the electric wire is used to heat the electric wire due to an iron loss generated in a snow melting wire rod to heat the electric wire to cause snow deposition. A ring method that attaches rings at regular intervals as a method of preventing snow from melting, preventing snow rotation, and preventing snow rotation, a snow removal robot that turns around by removing snow on the wires, a spiral snow removal wound around the wires There were a windmill attached to both ends of the section to remove snow by wind force, a method of weakening the adhesion of snow by wrapping a PTFT snow-resistant tape around a transmission line, and the development of other paints that are difficult to adhere.
[Problems to be Solved by the Invention] Although the above-mentioned countermeasures against snow melting and falling ice have been functioning and functioning, respectively, they have been completely and completely eliminated due to sudden heavy snow, wet snow, and temperature problems. It is not something that has succeeded in snowing, and there are many cases where it is not possible to cope with it even if multiple pieces are used in a superimposed manner.
[0004] In such a case, an actual countermeasure at the site is that a worker climbs a steel tower and impacts an electric wire with a hammer or a bat to remove ice and snow. Of course, it costs a lot of money at that time, but since high-voltage current is usually flowing through the tower, it is necessary to temporarily stop power transmission for safety at the time of work, which is more than a financial problem for power companies Is a matter of concern.
[0005] The icing snow on the overhead power transmission line causes the overhead power transmission line to be loosened, causing a disconnection accident, a danger of the wire hanging down on the ground and a short circuit, and a danger of gravity acting on the wire tilting or falling down the tower. The challenge is to resolve what has been described above because it is a natural disaster that can be brought and overlooked.
[Means for Solving the Problems] Under the circumstances described above, the present invention has been regarded as the last means in practice. By replacing ice and snow with simple equipment work and removing snow by manually or automatically driving, without cutting off high voltage current, realizing the elimination of danger associated with work at heights, saving costs, etc. The most realistic means of solving snow removal on overhead power transmission lines.
[Effects] The present invention is intended to drop the snow and ice accumulated on the overhead power transmission line by the impact of the hammer (3) of the snow removing device. When the snow removal device is automatically turned on, the hammer at the tip of the bar of the device strikes the transmission line, and the impact causes the transmission line to remove snow.
The cams (7, 9) of the original section are driven by a geared motor, and the follower section (5) at the middle of the curved bar (2) connected at one end to the base. Lift 10). At this time, since the bar is fixed to the base by the tension spring (6), the spring extends and the bar is attracted. As soon as the bar passes the highest point of the cam, the bar is attracted toward the base, and the impact causes the hammer portion. Hits the transmission line. The spring (6) doubles as a pressing spring, and also functions to prevent the hammer from constantly contacting the power line except at the moment of impact. (FIG. 1) is a place where the bar is pushed up by the cam with the pin and the spring is extended. (Figure 2) where the top of the normal cam passes, the bar is attracted, and the hammer hits the power line. (FIG. 3) is a double bar, double cam type according to claim 3, wherein the left-handed bar hits the transmission line and the right-handed bar is pushed up by the cam.
According to the fourth and sixth aspects, the rotary motion driven by the geared motor is converted by the crankshaft (16) and the articulated joint (17) into a horizontal or vertical motion of the lever, and the transmission line is hit. (Figs. 4 and 6) According to claims 5 and 7, the forward / reverse rotating geared motor installed on the rotating portion of the bar with the hammer is driven by the switch provided on the hammer portion being switched by the impact of the impact to change the rotating direction. . (FIGS. 5 and 7) When the rotation direction of the motor attached to the rotation axis of the bar is switched, the direction of the bar is switched. It is natural that even if the rotation direction of the motor is constant, the same movement can be obtained if the rotation is converted into the push-pull movement of the lever, which is a lever at the joint with the crank shaft.
According to an eighth aspect of the present invention, a magnetic coil (22) and a permanent magnet (23) are used as a driving principle, and the electrodes of the coil are switched by a switch. Operate. (FIG. 8)
According to the ninth and tenth aspects of the present invention, the operation is performed by the difference in gravity without using electricity. In both cases, snow falls on the snow receiving plate (25) and the weight of the snow is reduced by the other hammer (3) or the weight (26). ) When it becomes heavier, it falls down around the center of the bar as a fulcrum, and the accumulated snow is removed to reduce the weight. Thereafter, in the ninth aspect, the lifted hammer portion falls down by its own weight and gives an impact to the transmission line. (Fig. 9) is where the hammer hits after snow has been removed. In claim 10, when the weight of the snow piled on the hammer portion and the snow receiving plate exceeds the weight of the weight, the weight rises around the rotating portion of the bar as a fulcrum, and the hammer portion with the snow receiving plate lowered downwards. The snow is removed and the hammer is lifted up and is hit against the transmission line (19). The impact of the above causes the transmission line to drain snow. (FIG. 10)
[0012] The eleventh aspect is a method of operating the snow removing device only when necessary based on the judgment of the snowfall sensor and the electronic board. Various types of snowfall sensors have been developed, such as those that operate at humidity and temperature. However, if the size of the bar with the snow receiving plate according to claims 9 and 10 of the present invention is reduced and the snowfall sensor is activated when snow accumulates, the snowfall sensor can be used. It can also be used as Since it operates only when necessary, the energy saving effect is high.
According to a twelfth aspect of the present invention, in order to simplify the snow removing device and save electricity cost, electricity is supplied by a timer several times a day to operate the device even if there is snow or not even if there is no snow. . The timer is inexpensive and widespread even when it operates in the absence of snow, and the timer is inexpensive and popular, which helps to reduce the price of the entire apparatus.
[Embodiment] The snow removing apparatus of the present invention may not be able to completely remove snow with a simple impact depending on the nature of the snow at the site. Therefore, a horizontal impact is applied in addition to a vertical impact. You also need. In that case, the problem can be solved by using the snow removing device of the present invention in combination. The bar is plate-shaped in the drawing, but may be a pipe.
The difference between the first and second aspects is the difference in the type of the follower section and the original section of the cam section. According to the third aspect of the present invention, when the power transmission line is installed on a steel tower, the power transmission line generally extends right and left without interruption, and naturally snow is also accumulated on the left and right electric lines. Although this would solve the problem, it was devised because it is more economical to operate one geared motor and one geared motor as a whole. According to claim 1, two bars with a hammer having a half-moon-shaped follower are disposed symmetrically on the left and right, respectively. Instead, they are in the same direction.) The cams with the pins (8) driven into the discs, which are the original sections with the opposite timing, are attached to each bar and rotated by coaxial geared motors. The same applies to claim 2 except that a normal type cam is used. The reason why the timing was reversed was that if the bar was not lifted at the same time, it would not be necessary to double the power of the geared motor. good. Also, if the position of the cam is changed by using a plurality of pins or the shape of the cam itself is devised, it is possible to combine a large impact with a small impact to change the rhythm of the impact, such as ton-tata or ton-tata.
The snowplow of the present invention must be compactly installed at a high place because the overhead power transmission line is arranged on the arm of a tower. According to claim 4, installation can be made with a single support (15) supported on a steel frame or an added base.
The transmission line runs above the tower, and the way of attaching insulators and arranging the wires are apt depending on the site. The snow removal device for transmission lines of the present invention must also be compactly attached to the steel frame of the tower or to the steel frame added for installation, but the direction of the impact and the form of the hammer are oblique or downward depending on the needs of the site. You have to deal flexibly with body, lengthening and bending. In the case of the electric type, it does not choose the direction.
The fifth aspect differs from the fourth aspect in that it is driven by a geared motor that rotates forward and backward. Claims 4 and 5 are of the type in which the impact is applied alternately from below, whereas claims 6 and 7 are different in that the impact is applied simultaneously from the opposite direction.
The sixth and seventh aspects of the present invention relate to a snow blower in which a rotating part (32) rotates a central shaft (31) with respect to a transmission line to apply a hit mainly from a horizontal direction, but may be a vertical direction. As shown in FIG. 5, a plurality of bars can be connected as a link mechanism to cope with a plurality of transmission lines, and one power source can be used to simultaneously remove snow. In this case, if the hammer portion (30) is long in the vertical direction, it can cope with transmission lines arranged in the vertical direction. The hammer at this time is long enough to reach the transmission line below. Also, the effect of the straight bar (21) is the same whether the bar is not straight but has an S-shape or a Z-shape.
According to the eighth aspect, the operation utilizing the attraction and repulsion of the magnet generated by switching the electrodes of the permanent magnet (23) and the electromagnetic coil (22) for the operation power of the snow removing device has been described above. The same exercise can be performed.
A ninth aspect of the present invention relates to a case in which the apparatus is installed on a power transmission line, and is operated with natural energy, that is, the weight of snow falling when no power source is provided. It is a form to be installed. According to a similar principle, claim 10 is installed below the transmission line.
According to the eleventh and twelfth aspects of the present invention, it is not necessary to keep the snow removing device of the power transmission line running at all times, but it is preferable to operate only when the snow is entangled with the electric wire and does not fall naturally. It is intended to be able to automatically drive as short as possible.
If the tower does not have a suitable power supply for operating the snow removing device, a windmill or a solar cell may be installed on the tower and stored in the battery at all times, and the power supply may be used when necessary. In any case, since the staff at the site may patrol by car on a patrol, the device can be connected to the battery of the car and operated. In that case, if the electric wire is routed under the tower, it will not go up to the tower, and it can be turned on and off manually according to the local situation without a sensor or timer.
As for the hammer portion, the power transmission line may swing or hang down due to the weight of the wind or snow, so that the width of the hammer portion needs to be slightly increased. In addition, since a plurality of power transmission lines are usually stretched in parallel and in multiple stages, when a long bar-shaped hammer section (28, FIG. 11) straddling the power lines is used, the power transmission line running in parallel is once used by one snow removing device. You can also remove snow. Furthermore, if the above-mentioned long bar is arranged in multiple stages (29, FIG. 11) in order to cope with multiple stages of transmission lines, snow can be removed from the multiple stages of transmission lines at one time.
With respect to the hammer itself, the hammer itself can be mounted by being lifted by a push spring in order to prevent an excessively strong impact on the transmission line. In the case of a double switch, it is possible to use the fact that the spring is in contact with the spring contracting when hitting, so there is an effect of two birds per stone. Spring-loaded hammer (30).
Although the present invention is directed to snow removal of power transmission lines, the power transmission lines of steel towers are usually of high voltage, and therefore, when mounting the apparatus, special attention must be paid to the insulation of the base and the hammer. If the hammer portion or the like is lined with an insulating material (34) such as rubber, the hitting condition and the insulation may be good. At the same time, it is necessary to broadly reinforce the wire receiving protection material (13) of the same material in the portion where the wire is hit.
As for the electric drive, the present invention employs a geared motor (7). However, there are many off-the-shelf products which are small, have low rotation speed, have high torque, are powerful and are inexpensive. This is because it meets the purpose of the present invention which is compact, simple and inexpensive. Even if various speed reducers such as a pulley, a fan belt, and a planetary gear are used with a normal high-speed motor, the effect is not changed.
[Effects of the Invention] As described above, the present invention relates to a snow removing device for an overhead transmission line stretched over a steel tower. In the past, various manufacturers and electric power companies have made various efforts and developments, but even if they are effective, there is no perfection alone, and finally the danger of cutting off the tower current and causing workers to climb the tower The impact of the impact on the transmission line was caused by the impact of the snow and the snow was removed. The present invention seeks to mechanize even the last task with a simple snow removal device. Therefore, there are many advantages such as avoiding the danger of workers, reducing working costs, and avoiding temporary interruption of transmission lines.
There has been a track record of actually removing ice and snow due to the impact of a blow to a power transmission line up to the present, and its effects have been proven. According to the present invention, the operation is replaced with a simple snow removing device and the operation is mechanized, and the execution is high.
