Description
本発明は、高所作業車やドローン専用の屋根雪を温熱で融解消雪する屋根の勾配とほぼ同じ角度の形状にした平行四辺形型温熱消雪具に関するものである。This invention relates to a parallelogram-shaped thermal snow melting device, specifically designed for use with aerial work platforms and drones, which melts and removes snow from roofs using heat, and has a shape that is approximately the same angle as the slope of the roof.
雪国での除雪作業は雪の量及び湿った重い雪など雪の質によっては想像以上に重労働となる。数年ごと又は局地的に見舞われる大雪・豪雪では甚大な被害がもたらされている。湿気の少ない軽い雪が降り風で飛び散り、屋根雪を下す必要がなかった北海道などの北国でも気候変動・温暖化により湿った重い雪が降り積もる様になり屋根雪下ろしが必要になってきている。屋根雪下ろし中の転落や軒先の雪の落下、除雪作業での過労による人的被害も後を絶たず、少子高齢化により若者が少なくなり、地域により高齢者が自ら屋根雪下ろしや除排雪をせざるを得ず事故が増え、益々除雪作業、特に屋根雪下ろしは過酷なものになってきている。道路も車のスリップやスタックで渋滞になり雪害深刻であるが大型重機の普及で除雪・排雪作業は進歩している。しかし個人住宅地では依然として人力が頼りで、スコップや除雪用スノッパーで屋根雪を下ろし、小川や側溝へ排雪することになる。しかし、降雪期には小川や側溝はすぐに雪で溢れて流れず、雪の捨て場はなく山のように積まれて歩道通学路も通り難い状態が続いてしまう。Snow removal in snowy regions can be incredibly hard work, depending on the amount of snow and its quality, such as whether it's wet and heavy. Heavy snowfalls, occurring every few years or in localized areas, cause immense damage. Even in northern regions like Hokkaido, where light, dry snow used to fall and be blown away by the wind, eliminating the need to remove snow from roofs, climate change and global warming have led to the accumulation of wet, heavy snow, making roof removal necessary. Accidents such as falls during roof removal, snow falling from eaves, and injuries due to overwork during snow removal are all too common. With the declining birthrate and aging population, there are fewer young people, and in some areas, the elderly are forced to remove snow from roofs and clear snow themselves, leading to an increase in accidents and making snow removal, especially roof removal, an increasingly arduous task. Roads are also congested with cars slipping and getting stuck, and snow damage is serious, but snow removal and clearing operations are improving with the spread of large heavy machinery. However, in residential areas, manual labor is still relied upon, with snow being removed from roofs using shovels and snowplows and then dumped into streams and ditches. However, during the snowy season, streams and ditches quickly overflow with snow and cannot flow, leaving no place to dispose of the snow, resulting in mountains of snow that make it difficult to walk on sidewalks and school routes.
屋根雪下ろしを依頼した場合の標準作業価格（平成２９年度・福井県大野市）は屋根面積７６平方メートル（約２３坪）当たり１万４８００円。下ろした雪の処理費用は含まない。原則として弁当や用具は作業員が持参し、交通費は依頼者が実費負担となっている。屋根雪下ろしを必要とする時期は一時に重なるので少子高齢化で屋根雪下ろしを請け負う作業員が少なくなり、順番待ちが十日以上後になることが多くなっている。やむを得ず高齢者も屋根に上がる事が増え事故は絶えず、毎年死亡事故も起きている。年々作業価格も上昇し時間制の料金体制になって約倍の価格になっている場合もある。下ろした雪の処理は、流雪溝や雪捨て場がない場合では、トラックなどで公的に指定された雪捨て場に運ぶ時間も費用も多大なものになっている。人手不足で屋根雪下ろしが遅れて軒先が折れ、春になるまでブルーシートで補修している家屋が増えてきている。The standard price for roof snow removal (FY2017, Ono City, Fukui Prefecture) is 14,800 yen per 76 square meters (approximately 23 tsubo) of roof area. This does not include the cost of disposing of the removed snow. As a general rule, workers bring their own lunch and equipment, and the client is responsible for their own transportation costs. The period when roof snow removal is needed coincides with many other times of the year, and due to the declining birthrate and aging population, there are fewer workers willing to undertake roof snow removal, often resulting in waiting lists of 10 days or more. As more elderly people are forced to go up onto roofs, accidents are constant, and fatal accidents occur every year. The price of the work is rising year by year, and in some cases, the price has nearly doubled due to the introduction of an hourly rate system. Disposing of the removed snow is also a time-consuming and expensive process, as it must be transported by truck to a publicly designated snow disposal site if there are no snow drainage channels or designated snow disposal areas. Due to the labor shortage, roof snow removal is delayed, resulting in broken eaves, and an increasing number of houses are being repaired with blue tarpaulins until spring.
解決しようとする問題点の大雪による除雪・排雪に係る重労働を減少し、女性や高齢者また若者であっても、屋根雪下ろしという危険作業を少しでも避けて、平行四辺形の電熱プレートヒーター（１）で雪を融解消雪し減らすことで雪捨て場不足をも解消できる高所作業車の折り曲げブームやドローンを使った本発明の平行四辺形型温熱消雪具を提供することにある。The objective is to provide a parallelogram-shaped heated snow melting device that uses a folding boom of an aerial work platform or a drone, which reduces the heavy labor involved in snow removal and disposal caused by heavy snowfall, and allows women, the elderly, and young people to avoid dangerous work such as removing snow from roofs, while also solving the problem of snow disposal shortages by melting and reducing snow with a parallelogram-shaped electric heating plate heater (1).
実施例１として本発明の請求項１の折り曲げブーム取付け金具（１４）で中空形状の保持柄（３）を高所作業車などの折り曲げブームの先端に取り付け、高所作業車などの運転席に平行四辺形の電熱プレートヒーター（１）の防水絶縁被膜のコード（２）をのばして防水漏電防止回路を有するリモコンスイッチ（６）と電源（７）に繋ぎ設置する。屋根雪下ろしをする家の前で折り曲げブームを立ち上げ中空形状の保持柄（３）の一方の端に設けた平行四辺形電熱プレートヒーター（１）を屋根の軒先の左右どちらかの端から屋根の勾配に合わせた角度で屋根より約３０センチメートル浮かした位置を確認する。防水漏電防止回路を有するリモコンスイッチ（６）を入れてゆっくり雪に向かって水平に横異動させる。雪が数秒で溶けた後、さらに横に向かって移動させていく。軒先の部分の反対側の端まで移動させて一列目の消雪が終われば、次は軒先より一段上の奥へ平行四辺形電熱プレートヒーター（１）を移動させてゆっくり雪に向かって水平に横異動させて二列目を一列目とは逆方向へ消雪していく。次に屋根の頂上へ向かって三列目、四列目とこれを繰り返す。高所作業車の折り曲げブームを水平に移動させたり、高所作業車を前後に移動させたりしてこれを繰り返す。As Example 1, the folding boom mounting bracket (14) according to Claim 1 of the present invention is used to attach a hollow-shaped retaining handle (3) to the tip of a folding boom of an aerial work platform or the like. The waterproof insulating cord (2) of the parallelogram-shaped electric heating plate heater (1) is extended to the driver's seat of the aerial work platform or the like and connected to a remote control switch (6) with a waterproof leakage prevention circuit and a power supply (7). In front of the house where snow is to be removed from the roof, the folding boom is raised and the parallelogram-shaped electric heating plate heater (1) attached to one end of the hollow-shaped retaining handle (3) is positioned approximately 30 centimeters above the roof at an angle matching the slope of the roof, from either the left or right end of the eaves. The remote control switch (6) with a waterproof leakage prevention circuit is turned on and the heater is slowly moved horizontally toward the snow. After the snow melts in a few seconds, the heater is moved further horizontally. Once the first row of snow has been melted by moving the device to the opposite end of the eaves, the parallelogram-shaped electric heating plate heater (1) is moved one level higher and further back from the eaves, and slowly moved horizontally towards the snow to melt the second row in the opposite direction to the first row. Then, this process is repeated for the third and fourth rows towards the top of the roof. This is repeated by moving the folding boom of the aerial work platform horizontally or by moving the aerial work platform back and forth.
実施例２として本発明の請求項２の平行四辺形の電熱プレートヒーター（１）を水平面に対して、家屋の屋根の３寸勾配の１６．７度から４寸勾配の２１．８度位の勾配としたドローン専用屋根雪消雪の平行四辺形型温熱消雪具のヒーター面を垂直に立てて搭載したドローンを操縦して平行四辺形電熱プレートヒーター（１）を屋根の軒先の左右どちらかの端から屋根の勾配に合わせた角度で屋根より約３０センチメートル浮かした位置を確認する。防水漏電防止回路を有するリモコンスイッチ（６）を入れてゆっくり雪に向かって水平に横異動させる。雪が数秒で溶けた後、さらに横に向かって移動させていく。軒先の部分の反対側の端まで移動させて一列目の消雪が終われば、次は軒先より一段上の奥へ平行四辺形電熱プレートヒーター（１）を移動させてゆっくり雪に向かって水平に横移動させて二列目を一列目とは逆方向へ消雪していく。次に屋根の頂上へ向かって三列目、四列目とこれを繰り返す。As Example 2, the parallelogram-shaped electric heating plate heater (1) according to Claim 2 of the present invention is mounted vertically on a drone with a roof slope of approximately 16.7 degrees (3-inch slope) to 21.8 degrees (4-inch slope) relative to the horizontal plane. The drone is operated to confirm that the parallelogram-shaped electric heating plate heater (1) is positioned approximately 30 centimeters above the roof at an angle matching the roof slope, starting from either the left or right end of the eaves. The remote control switch (6) with a waterproof leakage prevention circuit is turned on and the device is slowly moved horizontally toward the snow. After the snow melts in a few seconds, the device is moved further horizontally. Once the first row of snow has been melted by moving it to the opposite end of the eaves, the parallelogram-shaped electric heating plate heater (1) is moved one level higher and further back from the eaves, and slowly moved horizontally toward the snow to melt the second row in the opposite direction to the first row. Next, the process is repeated toward the top of the roof for the third and fourth rows.
家の屋根の形や構造によっては高所作業車などを使っての作業が出来ない箇所もある。出来ない部分の消雪は本発明の請求項１の平行四辺形型温熱消雪具の平行四辺形電熱プレートヒーター（１）を中空形状の保持柄（３）に左右逆方向に取り付けて屋根に持って上がり防水絶縁被膜のコード（２）をのばし電源（７）に繋ぎ、中空形状の持ち柄（３）を両手で支えながら屋根の勾配に平行四辺形電熱プレートヒーター（１）を合わせ移動させるだけで体力を使わずに消雪していくことも可能である。ポータブル電源（７）を屋根に持って上がる事も可能である。電熱プレートヒーターの防水絶縁被膜のコード（２）は中空形状の保持柄（３）内で余裕の長さを保持する。Depending on the shape and structure of the house roof, there may be areas where work cannot be performed using aerial work platforms or similar equipment. For snow removal in these areas, it is possible to remove snow without expending much physical effort by attaching the parallelogram-shaped electric heating plate heater (1) of the parallelogram-shaped heated snow melting device according to claim 1 of the present invention to the hollow-shaped holding handle (3) in opposite directions, carrying it up to the roof, extending the waterproof insulating cord (2), connecting it to the power supply (7), and moving the parallelogram-shaped electric heating plate heater (1) to match the slope of the roof while supporting the hollow-shaped holding handle (3) with both hands. It is also possible to carry the portable power supply (7) up to the roof. The waterproof insulating cord (2) of the electric heating plate heater maintains a sufficient length within the hollow-shaped holding handle (3).
本発明のスイッチを入れ熱くなった平行四辺形電熱プレートヒーター（１）で順次屋根雪を消雪していくので下ろした大量の雪の処理の必要がなく、近くに流雪溝もなく大雪で雪の捨て場所がない場合や、体力的にスコップや除雪用スノッパーでの屋根雪下ろしが困難な時、また、屋根雪下ろしは地域一帯が同時期に緊急に必要となり依頼が集中し作業員が多忙で来られない時も体力を使わずに屋根雪を消雪出来る。スコップや除雪用スノッパーでの過酷な屋根雪下ろしでの事故も防ぐことができる。ドローンの性能は技術の進歩でより良い作業の可能性が期待される。The present invention uses a parallelogram-shaped electric heating plate heater (1) that is switched on and heated to sequentially melt the snow from the roof, eliminating the need to dispose of large amounts of removed snow. This is useful when there are no nearby snow drainage channels and no place to dispose of snow during heavy snowfall, or when it is physically difficult to remove snow from the roof with a shovel or snowplow. It is also useful when roof snow removal is urgently needed in an area at the same time, leading to a concentration of requests and making it difficult for workers to come, as it allows for snow removal without requiring physical effort. It also prevents accidents associated with the strenuous process of removing snow from roofs with shovels or snowplows. With advancements in drone technology, even better work possibilities are expected.
家の屋根の形や構造によっては高所作業車などを使っての作業が出来ない箇所もあるが、出来ない部分の消雪は本発明の請求項１の平行四辺形型温熱消雪具の平行四辺形電熱プレートヒーター（１）を中空形状の保持柄（３）に左右逆方向に取り付けて屋根に持って上がり、防水漏電防止回路を有するリモコンスイッチ（６）と電源バッテリー（７）をリックサックなどに担ぐかもしくは容器に入れて、雪上に置き、持ち柄（３）を両手で固定しながら移動させ消雪することが出来る。従来の屋根の勾配の下側からもしくは横から足を踏ん張ってスコップや除雪用スノッパーで雪をすくっては地上へ放り投げる作業は、腕や足腰を痛める事があったが、横異動するだけで力を入れなくてよいので安全で、雪に慣れていれば高齢者でも楽に屋根雪を処理する事が出来る。Depending on the shape and structure of the house roof, there may be areas where work cannot be done using aerial work platforms, but for snow removal in those areas, the parallelogram-shaped electric heating plate heater (1) of the parallelogram-shaped heated snow removal device according to claim 1 of the present invention is attached to a hollow-shaped holding handle (3) in opposite directions, carried up to the roof, and a remote control switch (6) with a waterproof leakage prevention circuit and a power battery (7) are carried in a backpack or placed in a container, placed on the snow, and the snow can be removed by moving the device while holding the holding handle (3) with both hands. Conventional work, which involves bracing oneself from the bottom or side of the roof slope and scooping up snow with a shovel or snow removal snowplow and throwing it to the ground, can strain the arms, legs, and waist, but this method is safe because it only requires lateral movement and does not require much force, and even elderly people can easily deal with roof snow if they are used to snow.
本発明の平行四辺形型温熱消雪具を用途により大型化、また形状を変えて除雪グレーダー、歩道用除雪車、救急車や消防車、鉄道のラッセル車などに取り付ける事で、豪雪で除雪・排雪が充分出来ない時も雪をその場で溶かしてしまう事でラッセルのパワー不足での鉄道運休や道路渋滞を緩和、減少する事が出来る。電源は携帯発電機や蓄電器を使用する事も可能である。道路渋滞の一因に大型トラックなどのスリップにより斜めに道路をふさぎ後続車が繋がってしまう事がある。進行方向はまだ積雪量は少ないけれど救援の除雪車が到着せず、次第に積雪が多くなり、２０２０年の冬は福井市の国道８号線は大渋滞になってしまった。初期段階で身軽な道路パトロール車などが、不通になっている進行方向から逆走をして本発明の平行四辺形型温熱消雪具を運び、スタックしたタイヤ周りの雪を融解消雪すれば大型トラックも自力走行が出来て大渋滞を防ぐ事が期待される。The parallelogram-shaped thermal snow melting device of the present invention can be enlarged and reshaped depending on the application and attached to snow graders, sidewalk snowplows, ambulances, fire trucks, and railway snowplows. This allows for the melting of snow on the spot even when snow removal and disposal are insufficient due to heavy snowfall, thereby mitigating and reducing railway service disruptions and road congestion caused by insufficient power from snowplows. Portable generators and battery storage devices can also be used as power sources. One cause of road congestion is when large trucks slip and block the road diagonally, causing a traffic jam of following vehicles. In the winter of 2020, National Route 8 in Fukui City became severely congested because, although the amount of snow in the direction of travel was still small, rescue snowplows had not yet arrived, and the snow gradually increased. It is expected that if a nimble road patrol vehicle could drive against the flow of traffic in the direction of the obstruction in the initial stages and deliver the parallelogram-shaped thermal snow melting device of the present invention, and melt the snow around the stuck tires, large trucks would be able to move under their own power, thus preventing major traffic jams.
１図において平行四辺形の電熱プレートヒータ（１）の上部と中空形状の保持柄（３）の上部を複数のボルト（８）で固定し電熱プレートヒーターの防水絶縁被膜のコード（２）を中空形状の保持柄（３）に設けたコード通し穴（４）に通し中空形状の保持柄（３）の下部のコード通し穴（５）から防水漏電防止回路を有するリモコンスイッチ（６）を介して電源（７）に繋ぐ。中空形状の保持柄（３）の下部に折り曲げブーム取付け金具（１４）をボルトで取り付ける。平行四辺形の電熱プレートヒーター（１）の上辺の角度は水平面に対して、家屋の屋根の３寸勾配の１６．７度から４寸勾配の２１．８度位の勾配とした平行四辺形型温熱消雪具。In Figure 1, the upper part of the parallelogram-shaped electric heating plate heater (1) and the upper part of the hollow-shaped retaining handle (3) are fixed together with multiple bolts (8). The waterproof insulating cord (2) of the electric heating plate heater is passed through a cord pass-through hole (4) provided in the hollow-shaped retaining handle (3), and connected to a power supply (7) via a remote control switch (6) with a waterproof leakage prevention circuit through a cord pass-through hole (5) at the bottom of the hollow-shaped retaining handle (3). A folding boom mounting bracket (14) is attached to the bottom of the hollow-shaped retaining handle (3) with bolts. The angle of the upper side of the parallelogram-shaped electric heating plate heater (1) is set to a slope of approximately 16.7 degrees (3-inch slope) to 21.8 degrees (4-inch slope) relative to the horizontal plane, which is the slope of a house roof.
図２においてねじ付き防水蓋（９’）を有する矩形のアルミケース（９）の内部に区切り保持板（９”）を設け電源バッテリー（７）と防水漏電防止回路を有するリモコンスイッチ（６）を設ける。アルミケース（９）の上部にドローンのジンバルへ接続のジンバル接続用取付け具（１０）を上端に有するアルミ製保持軸（１１）をリベットにて設ける。アルミ製保持軸（１１）の上部とアルミケース（９）の上部の両端を補強軸（１２）で三角形の形にリベットにて設ける。アルミケース（９）の下部にアルミ製の台形の形の中空形状の角型のフレーム（１３）をリベットにて設ける。フレーム（１３）の下部の一辺に平行四辺形の電熱プレートヒーター（１）の上部を複数のボルト（８）で固定し電熱プレートヒーターの防水絶縁被膜のコード（２）を中空形状のフレーム（１３）に設けたコード通し穴（４）に通し中空形状のフレーム（１３）のコード通し穴（５）からアルミケース（９）の下部に設けたコード通し穴（５’）に通し防水漏電防止回路を有するリモコンスイッチ（６）を介して電源バッテリー（７）に繋ぐ。平行四辺形の電熱プレートヒーター（１）の上辺及びフレーム（１３）の下部の一辺は水平面に対して、家屋の屋根の３寸勾配の１６．７度から４寸勾配の２１．８度位の勾配としたドローン専用屋根雪消雪の平行四辺形型温熱消雪具。In Figure 2, a rectangular aluminum case (9) with a screw-on waterproof cover (9') has a partition retaining plate (9'') inside which a power battery (7) and a remote control switch (6) with a waterproof leakage prevention circuit are installed. An aluminum retaining shaft (11) with a gimbal connection mounting fixture (10) for connecting to the drone's gimbal is attached to the top of the aluminum case (9) with rivets. The top of the aluminum retaining shaft (11) and both ends of the top of the aluminum case (9) are attached to each other with reinforcing shafts (12) in a triangular shape with rivets. A trapezoidal hollow rectangular frame (13) made of aluminum is attached to the bottom of the aluminum case (9) with rivets. A parallelogram is attached to one side of the bottom of the frame (13) The top of the electric heating plate heater (1) is fixed with multiple bolts (8), and the cord (2) of the electric heating plate heater's waterproof insulating coating is passed through a cord pass-through hole (4) provided in the hollow frame (13), and then through a cord pass-through hole (5') provided in the bottom of the aluminum case (9) from the cord pass-through hole (5) in the hollow frame (13), and connected to the power battery (7) via a remote control switch (6) having a waterproof leakage prevention circuit. The top side of the parallelogram-shaped electric heating plate heater (1) and one side of the bottom of the frame (13) are sloped with respect to the horizontal plane at a slope of approximately 16.7 degrees (3-inch slope) to 21.8 degrees (4-inch slope) of a house roof. This is a parallelogram-shaped heated snow melting device for drone-specific roof snow melting.
図２および図３においてドローン専用平行四辺形の電熱プレートヒーター（１）の上辺及びフレーム（１３）の下部の一辺は水平面に対して、家屋の屋根の３寸勾配の１６．７度から４寸勾配の２１．８度位の勾配としたドローン用平行四辺形電熱プレートヒーター（１）を屋根の軒先の左右どちらかの端から屋根の勾配に合わせた角度で屋根より約３０センチメートル浮かした位置を確認する。防水漏電防止回路を有するリモコンスイッチ（６）を入れてゆっくり雪に向かって水平に横異動させる。雪が数秒で溶けた後、さらに横に向かって移動させていく。軒先の部分の反対側の端まで移動させて一列目の消雪が終われば、次は軒先より一段上の奥へ平行四辺形電熱プレートヒーター（１）を移動させてゆっくり雪に向かって水平に横異動させて二列目を一列目とは逆方向へ消雪していく。屋根の頂上へ向かって三列目、四列目とこれを繰り返す。屋根の頂上側から作業をすると雪の溶けた水を軒先側の雪が吸収して屋根に負荷がかかり危険なので、必ず軒先側から下から上へと消雪していく。軒先側から作業をしても屋根から約３０センチメートル残した雪が溶かした水を吸収するが量が低いので溶けて雨樋へ流れる部分もあり屋根へ負荷がかからない。屋根の頂上付近は風に飛ばされる為わずかに積雪量が少なく、雪が降りやむと風や太陽の日差しで更に積雪量が減っていき、屋根の構造上からも軒先側より消雪する量は少なくしても良い。In Figures 2 and 3, the top edge and bottom edge of the frame (13) of the drone-specific parallelogram electric heating plate heater (1) are set to a slope of approximately 16.7 degrees (3-inch slope) to 21.8 degrees (4-inch slope) relative to the horizontal plane of the house roof. The drone-specific parallelogram electric heating plate heater (1) is positioned approximately 30 centimeters above the roof at an angle matching the roof slope, starting from either the left or right end of the eaves. The remote control switch (6) with a waterproof leakage prevention circuit is turned on and the heater is slowly moved horizontally toward the snow. After the snow melts in a few seconds, the heater is moved further horizontally. Once the first row of snow has been melted by moving it to the opposite end of the eaves, the parallelogram electric heating plate heater (1) is moved one level higher and further back from the eaves, and the heater is slowly moved horizontally toward the snow to melt the second row in the opposite direction to the first row. This process is repeated for the third and fourth rows toward the top of the roof. Working from the top of the roof is dangerous because the snow at the eaves absorbs the melted water, putting stress on the roof. Therefore, always start from the eaves and work your way up. Even when working from the eaves, the snow left about 30 centimeters above the roof will absorb the melted water, but the amount is small, so some of it melts and flows into the gutters, so it does not put stress on the roof. The snow accumulation near the top of the roof is slightly less because it is blown away by the wind, and once the snow stops falling, the amount of snow will decrease further due to the wind and sunlight. Due to the structure of the roof, it is acceptable to melt less snow near the top than from the eaves.
図４において折り曲げブーム取付け金具（１４）で中空形状の持柄（３）を高所作業車などの折り曲げブームの先端に取り付け、屋根雪下ろしをする家の前で折り曲げブームを立ち上げ、中空形状の保持柄（３）の一方の端に設けた平行四辺形電熱プレートヒーター（１）を屋根の軒先の左右どちらかの端から屋根の勾配に合わせた角度で屋根より約３０センチメートル浮かした位置を確認する。防水漏電防止回路を有するリモコンスイッチ（６）を入れてゆっくり雪に向かって水平に横異動させる。雪が数秒で溶けた後、さらに横に向かって移動させていく。軒先の部分の反対側の端まで移動させて一列目の消雪が終われば、次は軒先より一段上の奥へ平行四辺形電熱プレートヒーター（１）を移動させてゆっくり雪に向かって水平に横異動させて二列目を一列目とは逆方向へ消雪していく。屋根の頂上へ向かって三列目、四列目とこれを繰り返す。高所作業車の折り曲げブームを水平に移動させたり、高所作業車を前後に移動させたりしてこれを繰り返す。In Figure 4, the hollow handle (3) is attached to the tip of the folding boom of a high-altitude work vehicle or the like using the folding boom mounting bracket (14). The folding boom is raised in front of the house where snow is to be removed from the roof. The parallelogram-shaped electric heating plate heater (1), which is attached to one end of the hollow handle (3), is positioned approximately 30 centimeters above the roof at an angle matching the slope of the roof, starting from either the left or right end of the eaves. The remote control switch (6), which has a waterproof leakage prevention circuit, is turned on and the heater is slowly moved horizontally toward the snow. After the snow melts in a few seconds, the heater is moved further horizontally. Once the first row of snow has been removed by moving it to the opposite end of the eaves, the parallelogram-shaped electric heating plate heater (1) is moved one level higher and further back from the eaves, and the heater is slowly moved horizontally toward the snow to remove the second row of snow in the opposite direction to the first row. This process is repeated for the third and fourth rows toward the top of the roof. This process is repeated by moving the folding boom of the aerial work platform horizontally, or by moving the aerial work platform back and forth.
気候変動・温暖化の影響により日本海側では数年ごとに大雪に見舞われ、少子高齢化により高齢者の屋根雪下ろしの事故も増加している。２０１８年２月や２０２１年１月の国道８号線大渋滞で北陸豪雪、福井豪雪とも呼ばれ年間の平均降雪量のほとんどの量が短期間に降るドカ雪とも呼ばれている大雪は人的、経済的に及ぼす影響が大きい。近年、屋根雪の融雪に関しては瓦の下に電熱線を配置して瓦を温めるものと、ボイラーで温めた不凍液を瓦の上に設置した配管に循環させて直接積雪を融雪する方法があるが、どちらも設備費及びランニングコストが高価で普及し難く、しかも、雪の降り始めから作動させなければならず屋根雪下ろしを必要としない降り方の時も熱量を使う為、屋根雪下ろしの目安の１メートル程の積雪の時だけ数時間本発明の平行四辺形型温熱消雪具で融雪する方が光熱費は安価であり冬期間に使用する総エネルギーも少ない。本発明の平行四辺形型温熱消雪具を用途により大型化、また形状を変えて除雪グレーダー、歩道用除雪車、救急車や消防車、鉄道のラッセル車などに取り付ける事で、豪雪で除雪・排雪が充分出来ない時も雪をその場で溶かしてしまう事でラッセルのパワー不足での鉄道運休や道路渋滞を緩和、減少する事が出来る。電源は交流１００Ｖ１５００Ｗでもワット密度を上げる事で表面温度を６００℃位まで上げられる。冬期間だけでも２００Ｖ契約をして使用すれば大型化も可能である。携帯発電機や蓄電器などポータブル電源を使用する事も可能である。また、電熱より熱量が高いＬＰガスを使い、電熱プレートヒーター（１）に替えてＬＰガスコンロプレート（１）を除雪用スノッパーに搭載する事や、平行四辺形のＬＰガスコンロプレート（１）の上部と中空形状の保持柄（３）の上部を固定しＬＰガス供給ホース（２）を中空形状の保持柄（３）上部に設けたホース通し穴（４）に通し中空形状の保持柄（３）の下部に設けたホース通し穴（５）から防水漏電防止回路を有するリモコン点火スイッチ（６）を介してＬＰガスボンベ（７）に繋ぐ事も可能である。また、雪崩発生しやすい崖にはドローン２機を使って電熱線を配備したロープの両端の片方ずつを吊上げて事前に強制的に雪崩発生させる事も可能である。ドローンの性能は技術の進歩でより良い作業の可能性が期待される。Due to the effects of climate change and global warming, the Sea of Japan side of Japan is hit by heavy snowfall every few years, and the number of accidents involving elderly people removing snow from roofs is increasing due to the declining birthrate and aging population. Heavy snowfall, also known as "heavy snow," which causes major traffic jams on National Route 8 in February 2018 and January 2021 and is called the Hokuriku heavy snowfall or Fukui heavy snowfall, and is also called "heavy snow," where almost the entire average annual snowfall falls in a short period of time, has a significant impact on people and the economy. In recent years, there have been two methods for melting snow from roofs: one that places electric heating wires under the tiles to warm the tiles, and another that circulates antifreeze heated by a boiler through pipes installed above the tiles to directly melt the snow. However, both methods have high equipment and running costs, making them difficult to implement and widely adopted. Moreover, they must be activated from the start of snowfall, and heat is used even when snowfall does not require roof removal. Therefore, it is cheaper in terms of utility costs and total energy usage during the winter to use the parallelogram-type heated snow melting device of the present invention for a few hours only when the snow accumulation reaches about 1 meter, which is the guideline for roof removal. The parallelogram-shaped thermal snow melting device of this invention can be scaled up and modified in shape depending on the application, and attached to snow graders, sidewalk snowplows, ambulances, fire trucks, and railway snowplows. This allows for the melting of snow on the spot even when snow removal and disposal are insufficient due to heavy snowfall, thereby mitigating and reducing railway service disruptions and road congestion caused by insufficient power from snowplows. Even with a 100V 1500W AC power supply, the surface temperature can be raised to approximately 600°C by increasing the watt density. Larger sizes are possible if a 200V contract is made for use only during the winter months. Portable power sources such as portable generators and battery storage systems can also be used. Furthermore, it is possible to use LP gas, which has a higher heat output than electric heating, and mount an LP gas stove plate (1) on the snow removal snowplow in place of an electric heating plate heater (1). Alternatively, the top of the parallelogram-shaped LP gas stove plate (1) can be fixed to the top of the hollow-shaped retaining handle (3), and an LP gas supply hose (2) can be passed through a hose pass-through hole (4) provided on the top of the hollow-shaped retaining handle (3), and connected to an LP gas cylinder (7) via a remote ignition switch (6) with a waterproof leakage prevention circuit through a hose pass-through hole (5) provided on the bottom of the hollow-shaped retaining handle (3). In addition, on cliffs prone to avalanches, it is possible to use two drones to lift one end of a rope equipped with electric heating wires from each end to forcibly trigger an avalanche in advance. With advancements in drone technology, better work possibilities are expected.
