Description

本発明は、家庭や事務所や工場などのあらゆる建物に設置される太陽光発電パネル用の自動洗浄装置に関するものである。   The present invention relates to an automatic cleaning device for a photovoltaic power generation panel installed in any building such as a home, office or factory.

近年、京都議定書でも定められたような地球温暖化防止のための低炭素化社会への移行が世界的な動向となっており、各界で精力的に研究開発の努力が成され、今後更に、この傾向が強まっていくのは時代の趨勢であるが、それらのうち太陽光発電が主要な技術分野となっているけれども、現状は、装置が高価なことや発電効率の不足などからコストパフォーマンスに大きな問題があって、一般家庭などにおいては、政府或いは自治体の補助金をあてにして徐々に利用され始めているのが現状である。   In recent years, the transition to a low-carbon society to prevent global warming as defined by the Kyoto Protocol has become a global trend, and research and development efforts have been made energetically in various fields. Although this trend is becoming more prevalent, solar power generation is the main technological field, but the current situation is cost performance due to expensive equipment and lack of power generation efficiency. There is a big problem, and the current situation is that it is gradually being used in ordinary households with subsidies from the government or local government.

近い将来においては、大量生産と技術開発によって大きく改善されて極めて大量に採用されていくと思われるが、その際には、現状の太陽光発電パネルを数枚使用した一般家庭の屋根のごく一部を使用した初歩的ものではなく、例えば特許文献１に示すような屋根全体が太陽光発電パネルとなり、瓦などの代わりの屋根材として使用され美観、耐久性などを著しく向上する形態となっていくと思量される。 In the near future, it will be greatly improved by mass production and technological development, and it will be adopted in an extremely large amount. However, in that case, the roof of a general household using several photovoltaic panels is currently being used. For example, the entire roof as shown in Patent Document 1 is a photovoltaic power generation panel, and is used as a roofing material instead of tiles, and has a form that significantly improves aesthetics, durability, etc. It is thought to go.

その際に屋根上の太陽光発電パネルが、ホコリや雨水やゴミやコケや場所により火山灰、海塩、煤煙などで経時的に汚れることは避けられず、また一旦そのまま放置して汚れがこびりつくと容易に取ることが難しくなるという大きな問題があり、使用期間が長くなるにつれて太陽光の透過率が減少して、発電効率が著しく低下する現象があるが、人が定期的に屋根に上がって洗浄することは、滑ることやパネルの強度不足などから不可能であり、また屋根の中央付近のパネルが故障した場合においては、そのパネルだけを修理或いは取り替えるには、専門の業者がスミの方からパネルを外しながらそのパネルまで到達しなければならないなど著しく手間取りコストもかかる問題があった。   At that time, it is inevitable that the solar power generation panel on the roof will become dirty over time with volcanic ash, sea salt, smoke, etc. depending on dust, rainwater, garbage, moss, and location, and if it is left as it is, the dirt will stick. There is a big problem that it becomes difficult to take easily, and there is a phenomenon that the transmittance of sunlight decreases and the power generation efficiency decreases significantly as the usage period becomes longer, but people regularly go up to the roof and wash it It is impossible to do this because of slipping or insufficient strength of the panel, and if a panel near the center of the roof breaks down, a professional contractor will ask a specialist to repair or replace only that panel. There was a problem that it took a lot of time and labor, such as having to reach the panel while removing the panel.

これらの対策として、特許文献２には太陽電池パネル用の自動洗浄装置が提案されているが、自走式の水洗装置であり、コンパクトで簡便で安価にできるなどの効果を有する半面、傾斜の大きな屋根の洗浄では、洗浄機が落下する心配があって屋根によって使用できないことや洗浄ムラが出やすいことや洗浄機本体を屋根上に放置したままにしておくと紫外線や雨水などで経時的に著しく劣化しやすく、また美観も損ねるなどの問題があり、また取り込んで下に保存することは、洗浄機本体が重くて殆ど不可能な問題があった。   As these countermeasures, Patent Document 2 proposes an automatic cleaning device for a solar cell panel, but is a self-propelled water cleaning device, which has an effect of being compact, simple and inexpensive, and having an inclined surface. When cleaning large roofs, there is a risk of the cleaning machine falling and it cannot be used depending on the roof, cleaning unevenness is likely to occur, and if the cleaning machine body is left on the roof, it may be affected by ultraviolet rays or rainwater over time. There are problems such as remarkably easy deterioration and loss of aesthetics, and there is a problem that it is almost impossible to take in and store underneath because the washing machine body is heavy.

特開２００４−３３２２００号公報JP 2004-332200 A 特開２００２−２７３３５１号公報JP 2002-273351 A

本発明においては、太陽光発電パネルが経時的に汚れて発電効率が著しく低下することやパネルの修理や取替えの難しい問題を解決することを課題としており、更に従来の技術では傾斜の大きな屋根に使用できないことや洗浄ムラが出やすいことや洗浄機を屋根上に放置したままにしておくと紫外線や雨水などで使用されているプラスチック部品やゴムベルトや金属部品が経時的に著しく劣化しやすく、また美観も損ねるなどの問題を解決することと、発電効率を十年以上の寿命期間に亘って新設時の少なくとも95％以上を維持することを課題としている。 In the present invention, it is an object to solve the problem that the photovoltaic power generation panel is soiled with time and the power generation efficiency is remarkably reduced and the panel is difficult to repair or replace. If it cannot be used, cleaning unevenness is likely to occur, or if the washer is left on the roof, plastic parts, rubber belts, and metal parts used in ultraviolet rays and rainwater are likely to deteriorate over time. The challenge is to solve problems such as the loss of aesthetics and maintain at least 95% of the power generation efficiency over the lifetime of more than 10 years.

前記課題を解決するために、屋根上の所定位置にラックレールなどのレールを設置し、その中間に太陽光発電パネルを敷き詰めて固定してから、当該レールと相応したギア輪などの車輪と回転ブラシなどを敷設した細長い洗浄装置本体が、当該レール上をガイド機構によって上下左右方向を定めて自動走行可能に設置され、屋根の最頂部などに設置されている水供給管から水と必要により少量の洗剤なども供給しながら回転ブラシなどで定期的に自動洗浄可能する形態となっていて、洗浄しない時には、洗浄装置本体は屋根の軒下に太陽光や雨水などを避けて日陰に目立たずに収納可能な構成となっており、また故障したパネルの修理などにおいては、作業者が洗浄装置本体の上に乗って手動で移動可能にして、目的のパネルだけを極めて容易に修理したり点検できる手段を採用した。 In order to solve the above-mentioned problem, a rail such as a rack rail is installed at a predetermined position on the roof, and a photovoltaic power generation panel is laid and fixed in the middle, and then a wheel such as a gear wheel corresponding to the rail is rotated. The main body of the long and thin cleaning device laid with brushes is installed on the rail so that it can automatically run with the guide mechanism set up and down, left and right, and water and a small amount if necessary from the water supply pipe installed at the top of the roof etc. It can be automatically cleaned regularly with a rotating brush while supplying other detergents, etc. When not cleaning, the main body of the cleaning device is stored under the roof eaves so as not to stand out in the shade by avoiding sunlight and rainwater When repairing a broken panel, the operator can get on the main body of the cleaning device and manually move it so that only the desired panel can be accommodated. It adopted the means that can be inspected or repaired.

上記手段の採用によって、太陽光発電パネルが経時的に汚れて発電効率が低下することやパネルの修理や取替えの著しく難しい問題を解決することができ、更に従来の装置では、傾斜の大きな屋根に適用できないことや洗浄ムラが出やすいことや洗浄機を屋根上に放置したままにしておくと紫外線や雨水などで劣化しやすく、また美観も損ねるなどの問題を解決することができ、更に定期的に洗浄することによって発電効率を十年以上の寿命期間に亘って新設時の少なくとも95％以上を維持することを容易にできるなどの多大な効果を奏する。 By adopting the above-mentioned means, it is possible to solve the problem that the photovoltaic power generation panel becomes dirty over time and the power generation efficiency is lowered, and the remarkably difficult problem of repair and replacement of the panel is solved. Problems such as inapplicability, easy cleaning unevenness, and the possibility of deterioration due to ultraviolet rays, rainwater, etc. and loss of aesthetics can be solved if the cleaning machine is left on the roof. By cleaning the power generation efficiency, it is possible to easily maintain at least 95% of the power generation efficiency at the time of new installation over a lifetime of 10 years or more.

本発明に係る一実施例の太陽光発電パネル自動洗浄装置の概略の設置形態を示す斜視図である。It is a perspective view which shows the schematic installation form of the solar power generation panel automatic cleaning apparatus of one Example which concerns on this invention. 本発明に係る一実施例の洗浄装置本体の自動洗浄時の概略の構成を示す拡大側面図である。It is an enlarged side view which shows the structure of the outline at the time of the automatic washing | cleaning of the washing | cleaning apparatus main body of one Example which concerns on this invention. 本発明に係る一実施例のラックレール上を洗浄装置が移動している時のギア輪付近の拡大正面図である。It is an enlarged front view of the vicinity of the gear wheel when the cleaning device is moving on the rack rail of one embodiment according to the present invention.

図１は、本発明に係る一実施例を示す太陽光発電パネル自動洗浄装置の概略の設置形態を示す斜視図であるが、太陽光発電パネル１の敷設された一般家庭などの家の南側の屋根部３の所定位置にラックレールなどのレール２が屋根の斜面の直下方向に平行に複数本敷設され、当該レール上を上下方向に移動可能にした屋根上の太陽光発電パネル１の幅寸法の細長い洗浄装置本体４が屋根の斜面の上下方向に落下することなく移動可能となっており、当該洗浄装置本体４には本体駆動モーター５とブラシ駆動モーター６が取り付けられて、両端部のレール２に設けられた電源からスライドしながら交流または直流電気を取得するなどの方法でブラシ７の高速回転と洗浄装置本体４の移動を可能とし、複数本のレール２の下方の端部は、そのまま180度程度を適度の半径で曲面状に曲げられており、当該洗浄装置が作動していない通常の時に軒下の本体収納庫８の中に洗浄装置本体４を逆さまに収納可能な形態となっている。なお、洗浄装置本体８を南側の軒下に収納保管する構成を前記したが、これに限定されず、例えば北側の軒下に収納する構成であってもよい。 FIG. 1 is a perspective view showing a schematic installation form of an automatic photovoltaic power generation panel cleaning apparatus according to an embodiment of the present invention, but on the south side of a home such as a general household where a photovoltaic power generation panel 1 is laid. The width dimension of the photovoltaic panel 1 on the roof in which a plurality of rails 2 such as rack rails are laid in parallel at a predetermined position of the roof portion 3 in a direction directly below the slope of the roof and are movable in the vertical direction on the rail. The main body drive motor 5 and the brush drive motor 6 are attached to the main body drive motor 5 and the rails at both ends. The brush 7 can be rotated at a high speed and the cleaning device body 4 can be moved by a method such as acquiring AC or DC electricity while sliding from a power source provided in the power source 2, and the lower end portions of the plurality of rails 2 remain as they are. 1 About 80 degrees is bent into a curved surface with an appropriate radius, and the cleaning device body 4 can be stored upside down in the main body storage 8 under the eaves when the cleaning device is not operating normally. Yes. In addition, although the structure which accommodates and stores the washing | cleaning apparatus main body 8 under the eaves of the south side was described above, it is not limited to this, For example, the structure accommodated under the eaves of the north side may be sufficient.

そしてタンク９に雨水を溜めておき、定期的に洗浄する時には揚水ポンプ１０を作動させて屋根の頂点付近に設置した水供給管１１の細孔から雨水と必要によって少量の洗剤を供給しながら噴出させると同時にブラシを移動しながら高速回転して自動洗浄する機構となっている。なお、水を供給する位置は、前記した屋根の頂点付近に限定されず、例えば洗浄装置本体に直接取り付けて供給する方法を採用しても差し支えなく、また使用する水は、水道水でも差し支え無いが、通常の水道水には炭酸カルシウムなどの塩類が含有されているために一般に水垢と言われる物質がパネルの表面に強固に付着する問題があるため、少量の水垢除去剤の添加をするなどの対策を要する。 Then, rainwater is stored in the tank 9, and when periodically washed, the pump 10 is operated and ejected while supplying rainwater and a small amount of detergent as needed from the pores of the water supply pipe 11 installed near the top of the roof. At the same time, it is a mechanism that rotates at high speed while moving the brush and performs automatic cleaning. In addition, the position for supplying water is not limited to the vicinity of the top of the roof as described above. For example, a method of directly attaching and supplying water to the cleaning apparatus main body may be adopted, and the water used may be tap water. However, because normal tap water contains salts such as calcium carbonate, there is a problem that substances commonly called scales adhere firmly to the surface of the panel, so a small amount of scale removal agent is added. It is necessary to take measures.

更に詳しく説明すると、図２は洗浄装置本体４の自動洗浄時の概略の構成を示す側面図であるが、本体駆動モーター５とブラシ駆動モーター６を上部に設けた構造基板１３の下部の端部付近の二ヶ所に車軸支持バー１５を垂下し、当該車軸支持バー１５の中間程度の位置にベアリングなどを介して車軸１６が設けられ、当該車軸１６にはラックのあるレール２のギアの形状に合わせたギア輪などの車輪１２が固定されて屋根の斜面を落下することなく上下動可能に敷設されており、また構造基板１３の下部の中間程度の位置にブラシ用バー１８を垂下し、ブラシ７の外径寸法から洗浄に適切な位置にブラシ軸１７が、ベアリングを介して設けられ、ブラシ駆動モーター６の回転力をギアベルト１４で伝達してブラシ７を高速回転させる構成となっており、更にラックレール２の側面の両側には、ガイド用凹溝１９が設けられ、車軸支持バー１５の下端部付近に設けた突起などと嵌合して摺動するなどのガイド機構によってギア輪１２が脱輪を防止すると同時に、逆さまになっても落下することなく屋根の軒下に逆さまに収納可能な構成となっている。なお、洗浄機の洗浄素材については、ブラシを使用すると前記したが、本発明においては、これに限定されるものではなく、例えば発泡ウレタンや不織布などの軟質素材を短冊状に細長く切ったものを回転しながら接触する方法や自動車のワイパーと同様なゴムなどの軟質素材のスキージで擦り取る方法など接触して物理的な方法で洗浄するあらゆる方法を採用可能であり、また、車輪にギア輪を採用した例を前記したが、これに限定されるものではなく、例えば通常の車輪を採用して屋根頂部付近に設置したワイヤ巻取り装置によってワイヤで繋いで吊って落下することなく上下動可能にする方法などを採用しても差し支えなく、どちらかと言えば、この方式の方が装置が単純で安価にできる。   More specifically, FIG. 2 is a side view showing a schematic configuration at the time of automatic cleaning of the cleaning apparatus main body 4, but the lower end portion of the structural substrate 13 provided with the main body driving motor 5 and the brush driving motor 6 on the upper side. An axle support bar 15 is suspended at two nearby locations, and an axle 16 is provided at a position about the middle of the axle support bar 15 via a bearing or the like. The axle 16 has a gear shape of the rail 2 with a rack. A wheel 12 such as a combined gear wheel is fixed and laid so as to be movable up and down without falling on the slope of the roof. A brush bar 18 is suspended at a middle position below the structural substrate 13 to provide a brush. The brush shaft 17 is provided through a bearing at a position suitable for cleaning from the outer diameter size of the roller 7, and the rotational force of the brush drive motor 6 is transmitted by the gear belt 14 to rotate the brush 7 at a high speed. Further, a guide groove 19 is provided on both sides of the side surface of the rack rail 2 and is guided by a guide mechanism such as a fitting and sliding with a protrusion provided near the lower end of the axle support bar 15. The gear wheel 12 prevents the wheel from being removed, and can be stored upside down under the eaves of the roof without falling even if it is turned upside down. As for the cleaning material of the cleaning machine, as described above when a brush is used, the present invention is not limited to this. For example, a material obtained by cutting a soft material such as urethane foam or nonwoven fabric into a strip shape. Any method of contacting and cleaning with a physical method such as a method of contacting while rotating or a method of scraping with a soft material squeegee such as rubber similar to a car wiper can be adopted, and a gear wheel is attached to the wheel. Although the example adopted is not limited to this, for example, it is possible to move up and down without falling by hanging with a wire winding device installed near the roof top using a normal wheel and suspended by a wire However, this method can be simpler and less expensive.

更に詳しく説明すると、図３はラック状のレール２上を洗浄装置が移動している洗浄時の図２のギア輪付近の拡大正面図であるが、構造基板１３から車軸支持バー１５がレール２に対向して摺るように二本を垂下し、下方に所定位置に設けられた突起部２０がレールの中間位置に設けられたガイド用凹溝１９と寸法精度良く挟んで摺動可能になっており、ブラシ７を高速回転しながら屋根上を自由に上下に移動して水と少量の洗剤などの薬剤と共に自動洗浄する構成となっている。   More specifically, FIG. 3 is an enlarged front view of the vicinity of the gear wheel of FIG. 2 when the cleaning device is moving on the rack-like rail 2. The two protrusions hang down so as to slide against each other, and the protrusion 20 provided at a predetermined position below can be slid between the guide groove 19 provided at the intermediate position of the rail with good dimensional accuracy. In addition, the brush 7 is freely moved up and down on the roof while rotating at high speed, and is automatically cleaned together with water and a small amount of a detergent such as a detergent.

また、太陽光発電パネル１の一部に故障が発生して修理或いは交換が必要となった時や点検する時には、洗浄装置本体４の上に、落下防止用の柵などを設けた専用の補助装置を取り付けて、上に作業者が乗って手動で移動することによって目的のパネルだけを極めて簡単に修繕することができる。   In addition, when a failure occurs in a part of the photovoltaic power generation panel 1 and it is necessary to repair or replace it, a dedicated auxiliary device provided with a fence for preventing fall on the cleaning device body 4 is provided. Only the target panel can be repaired very easily by mounting the device and manually moving the operator on it.

本発明においては、発電効率を常に測定して劣化を把握して、基準レベル以下になったら洗浄装置を作動させたり、或いは一定期間毎に作動させるなどコンピュータ制御によって自動管理することが望ましい。 In the present invention, it is desirable that the power generation efficiency is always measured to grasp the deterioration, and automatically managed by computer control, such as operating the cleaning device when it falls below the reference level, or operating at regular intervals.
