本考案は鉄塔への着氷雪を防止するための改良

［従来の技術］
送電線への着雪事故については、毎年のように
報告されているが、鉄塔への着雪事故となると、

らである。[Conventional technology] Snow accretion accidents on power transmission lines are reported every year, but when it comes to snow accretion accidents on steel towers,
It is generally unfamiliar. However, in reality, ice and snow accretion on steel towers poses as big a problem as the ice and snow accretion on power transmission lines. In other words, the collapse of a steel tower due to ice and snow is not only caused by the effects of ice and snow on power transmission lines spreading to the tower, but is surprisingly often caused by snow accumulating on the tower itself.
かかる鉄塔倒壊事故を防止するには、鉄塔に着
氷雪が起らないようにする必要があるが、従来は
そのための余り有効な手段がなく、最も実用的な
手段として、鉄塔にヒーター線を巻き付ける方法
が検討された程度であつた。 In order to prevent such tower collapse accidents, it is necessary to prevent ice and snow from forming on the tower, but until now there has been no effective means for this, and the most practical method is to wrap heater wires around the tower. The methods were only considered.
［考案が解決しようとする問題点］

とはいえなかつた。[Problem that the invention attempts to solve] The method of wrapping the above heater wire around the steel tower is as follows.
It is necessary to supply power from outside, which not only makes the equipment bulky, but also requires a large amount of electricity to have sufficient snow melting effect, making the equipment expensive and requiring constant maintenance and inspection. It wasn't necessarily perfect.
［問題点を解決するための手段］

ことにある。[Means for Solving the Problems] The present invention has been made in view of the above-mentioned circumstances, and provides a steel tower mount that does not require the above-mentioned power supply, has a simple structure, is inexpensive, and can exhibit reliable effects. The aim is to provide an ice and snow prevention device, and its gist is to attach heat collection fins to a shape memory alloy wire rod that can change its shape depending on the temperature during ice and snow formation, and to place these around the outer periphery of the steel tower. It's what I did.
［実施例］ 以下に実施例に基いて説明する。[Example] This will be explained below based on examples.

ある。 FIG. 1 is an explanatory diagram showing a state in which the snow accretion prevention device according to the present invention is attached to a pipe-type steel tower member 1. 3 is a shape memory alloy wire wound into a coil around the steel tower member 1; 4 is a heat collecting fin attached to the shape memory alloy wire 3 by an attachment piece 5;
Reference numeral 2 indicates a fixing member fixing one end of the shape memory alloy wire 3 to the steel tower member 1, and reference numeral 10 indicates snow that has fallen on these. The shape memory alloy wire 3 is in an elongated state as shown in Fig. 1 at normal temperature, but when the temperature reaches 0°C, for example, when it is frozen and snowed, it becomes a contracted shape as shown in Fig. 2. is memorized. By shrinking in this way, the snow 10 that has fallen on the steel tower member is scraped off by the shape memory alloy wire 3 as the shape changes.

The shape memory alloy wire 3 returns to the state shown in FIG. 1, which is the initial memorized shape. Therefore, if there is any new snow that has fallen after the snow has shrunk, it will be scraped off during this return process.

It is fixed and fixed. By connecting the shape memory alloy wire and the spring in this manner, the spring 6 appropriately complements the shape deformation behavior of the shape memory alloy wire 3. Further, by using a spring in combination in this way, another feature can be exhibited in that the amount of shape memory alloy wire used can be reduced.

At the same time, the snow falling effect has been made even better.
