Description

洗浄装置Cleaning device
　本発明は、洗浄装置、特に太陽光発電装置の洗浄装置に関する。 The present invention relates to a cleaning device, and more particularly to a cleaning device for a solar power generation device.
　近年、環境保護の観点から、太陽光を電力に変換するソーラーパネル（太陽電池）を屋根に設置する家庭が増加している。また、世界規模で石油／原子力の代替エネルギーについての議論が行われており、太陽光発電などの再生可能エネルギーの買取制度の施策が実施され、企業、自治体、電力会社などにおいては、より大型な太陽光発電所を経営し、発電した電力の自社活用、売電による電力事業が行われるようになってきている。 Recently, from the viewpoint of environmental protection, an increasing number of households install solar panels (solar cells) that convert sunlight into electric power on the roof. In addition, there are discussions on alternative energy for oil / nuclear energy on a global scale, and measures for purchasing renewable energy such as solar power are being implemented. The solar power plant is managed, and the electric power business by the in-house utilization of the generated electric power and the sale of electric power is being carried out.
　これまで、ソーラーパネルは、雨などで表面上の汚れが取れるなど、メンテナンスフリーで発電できるとされていた。しかしながら、ソーラーパネルは、太陽光により発電するため、表面に枯れ葉やほこり等の汚れが付着すると、発電する電力量が急激に低下する。特に、砂漠／乾燥地帯などの降雨量の少ない地域、火山灰、黄砂、雪などの堆積物が多い地域では、年間を通して効率よく発電するためにソーラーパネル表面の汚れを清掃する必要があり、清掃作業を行っている。 Until now, solar panels were supposed to be able to generate electricity without maintenance, such as removing dirt on the surface due to rain. However, since the solar panel generates power by sunlight, if dirt such as dead leaves or dust adheres to the surface, the amount of power to be generated rapidly decreases. Especially in areas with low rainfall, such as desert / dry areas, and areas with a lot of deposits such as volcanic ash, yellow sand, and snow, it is necessary to clean the solar panel surface for efficient power generation throughout the year. It is carried out.
　例えば、特許文献１に太陽電池パネル用清掃装置が示されている。特許文献１の太陽電池パネル用清掃装置は、太陽電池パネルの受光面に接触した状態で移動するブレード部を有する清掃部と、受光面の汚れ状態を認識する認識部と、降雨状態の検知を行うレインセンサと、清掃部を動作させる制御部とを有する。 For example, Patent Document 1 discloses a cleaning device for a solar battery panel. The cleaning device for solar cell panel of Patent Document 1 includes a cleaning unit having a blade unit that moves in contact with the light receiving surface of the solar cell panel, a recognition unit for recognizing the dirt state of the light receiving surface, and detection of a rain state.

In the description of the embodiments, for the sake of convenience of explanation, upper, lower, left, and right expressions are used. However, these expressions are based on the drawings and do not limit the configuration of the invention.
　図１は、太陽光発電装置２００に本実施形態に係る洗浄装置１００を設置した状態を示す平面図であり、図２は、太陽光発電装置２００と本実施形態に係る洗浄装置１００の側面図である。 FIG. 1 is a plan view showing a state in which the cleaning device 100 according to the present embodiment is installed in the solar power generation device 200, and FIG. 2 is a side view of the solar power generation device 200 and the cleaning device 100 according to the present embodiment. It is.
　太陽光発電装置２００は、列状に連結された複数の太陽電池モジュール２１０によって構成されている。太陽電池モジュール２１０には、太陽電池モジュール２１０の周辺を保護するためのフレーム２１１が設けられている。隣り合う太陽電池モジュール２１０は、フレーム２１１部分に固定部材２２０が取り付けられて架台２３０に固定されている。 The solar power generation apparatus 200 includes a plurality of solar cell modules 210 connected in a row. The solar cell module 210 is provided with a frame 211 for protecting the periphery of the solar cell module 210. Adjacent solar cell modules 210 are fixed to a frame 230 with a fixing member 220 attached to the frame 211 portion.
　固定部材２２０は、例えば、金具２２１とボルト２２２で構成されている。図１では、左右に隣接する２つの太陽電池モジュール２１０が２つの固定部材２２０で固定されているが、固定部材２２０の個数や配置は太陽電池モジュール２１０の設置状態により適宜調整される。 The fixing member 220 includes, for example, a metal fitting 221 and a bolt 222. In FIG. 1, two solar cell modules 210 adjacent to the left and right are fixed by two fixing members 220, but the number and arrangement of the fixing members 220 are appropriately adjusted according to the installation state of the solar cell modules 210.
　また、図２に示すように、太陽電池モジュール２１０と設置基準面Gとの設置角度及び高さは設置状態により適宜選択される。設置角度については、発電量等を考慮して１０～３０°程度に設定される。設置基準面G自体は、屋根のように傾いている場合もあり得る。 Moreover, as shown in FIG. 2, the installation angle and height of the solar cell module 210 and the installation reference plane G are appropriately selected depending on the installation state. The installation angle is set to about 10 to 30 ° in consideration of the amount of power generation. The installation reference plane G itself may be inclined like a roof.
　洗浄装置１００は、被洗浄面である太陽電池モジュール２１０の表面（受光面）に洗浄液を吐出するためのノズル１０と、被洗浄面に押し当てて洗浄液を払拭するブレード２０とを備える。また、洗浄装置１００は、移動部として太陽電池モジュール２１０のフレーム２１１上を走行するための走行輪３０と、太陽電池モジュール２１０から洗浄装置１００の脱落を防止するためのガイド機構３５を備え、列状に連結された複数の太陽電池モジュール２１０の列（水平）方向に走行できるように構成されている。 The cleaning apparatus 100 includes a nozzle 10 for discharging the cleaning liquid to the surface (light receiving surface) of the solar cell module 210 that is the surface to be cleaned, and a blade 20 that presses against the surface to be cleaned and wipes the cleaning liquid. The cleaning device 100 includes a traveling wheel 30 for traveling on the frame 211 of the solar cell module 210 as a moving unit, and a guide mechanism 35 for preventing the cleaning device 100 from falling off the solar cell module 210. It is comprised so that it can drive | work in the row | line | column (horizontal) direction of the several solar cell module 210 connected in the shape.
　したがって、本実施形態に係る洗浄装置１００は、他のパネルの列に移動させながら往復させたり、パネルの列数分連結させることにより、被洗浄面全面を効率的に洗浄することができる。以降では、洗浄装置１００の進行方向をＸとし、太陽電池モジュール２１０の表面と平行かつＸ方向と直交する方向をＹとし、太陽電池モジュール２１０の表面と垂直方向をＺとして説明する。 Therefore, the cleaning apparatus 100 according to this embodiment can efficiently clean the entire surface to be cleaned by reciprocating while moving to another panel row or connecting the same number of panels. Hereinafter, the traveling direction of the cleaning device 100 will be described as X, the direction parallel to the surface of the solar cell module 210 and perpendicular to the X direction as Y, and the direction perpendicular to the surface of the solar cell module 210 as Z.
　（洗浄装置１００の構成）
　図３は、第１の実施形態に係る洗浄装置１００の構成を示す平面図であり、図４は、洗浄装置１００の側面図である。なお、図４では、ガイド機構３５等の一部の構成要素を省略して示している。 (Configuration of the cleaning apparatus 100)
FIG. 3 is a plan view showing the configuration of the cleaning apparatus 100 according to the first embodiment, and FIG. 4 is a side view of the cleaning apparatus 100. In FIG. 4, some components such as the guide mechanism 35 are omitted.
　図４に示すように、洗浄装置１００は、上述したノズル１０、ブレード２０、走行輪３０、ガイド機構３５以外に、タンク１１、ポンプ１２、配管１３、ホース１４、バッテリー２５、モータ３１、及び、これらを保持する保持部材４０を備えている。なお、タンク１１及びポンプ１２は、必ずしも洗浄装置１００に搭載する必要はなく、メガソーラー発電所内の所定箇所に設置して、洗浄装置１００に長尺ホースで接続してもよい。 As shown in FIG. 4, the cleaning apparatus 100 includes a tank 11, a pump 12, a pipe 13, a hose 14, a battery 25, a motor 31, and the nozzle 10, the blade 20, the traveling wheel 30, and the guide mechanism 35 described above. A holding member 40 for holding them is provided. The tank 11 and the pump 12 are not necessarily mounted on the cleaning device 100, and may be installed at a predetermined location in the mega solar power plant and connected to the cleaning device 100 with a long hose.
　タンク１１に貯蔵する洗浄液としては、例えば、水道水等の水を使用しているが、洗剤等の薬剤を含有させると洗浄性が向上し、洗浄液としてより好ましい。 As the cleaning liquid stored in the tank 11, for example, water such as tap water is used. However, when a chemical such as a detergent is included, the cleaning property is improved and the cleaning liquid is more preferable.
　移動部として保持部材４０に設けられる走行輪３０は、洗浄装置１００の進行方向を前方として、保持部材４０の前後及び左右に配置され、少なくとも１つの走行輪３０がモータ３１によって駆動される。走行輪３０は、太陽電池モジュール２１０のフレーム２１１上に接触し、保持部材４０に取り付けられたノズル１０及びブレード２０と、被洗浄面である太陽電池モジュール２１０の表面との間隔（Ｚ方向）が一定に保たれる。 The traveling wheels 30 provided on the holding member 40 as a moving part are arranged on the front and rear and the left and right of the holding member 40 with the traveling direction of the cleaning device 100 as the front, and at least one traveling wheel 30 is driven by the motor 31. The traveling wheel 30 is in contact with the frame 211 of the solar cell module 210, and the distance (Z direction) between the nozzle 10 and the blade 20 attached to the holding member 40 and the surface of the solar cell module 210 that is the surface to be cleaned. Kept constant.
　洗浄装置１００の動作は、モータ３１が走行輪３０を駆動させることで行われる。本実施形態では、モータ３１の回転軸を直近の走行輪３０に直接連結する１輪駆動形態となっているが、モータ３１の駆動力をシャフト・軸受け・タイミングベルト等で各走行輪３０に伝達し２輪駆動や４輪駆動にしても良い。 The operation of the cleaning apparatus 100 is performed by the motor 31 driving the traveling wheels 30. In the present embodiment, a single-wheel drive mode in which the rotation shaft of the motor 31 is directly connected to the nearest traveling wheel 30 is transmitted, but the driving force of the motor 31 is transmitted to each traveling wheel 30 by a shaft, a bearing, a timing belt, or the like. However, two-wheel drive or four-wheel drive may be used.
　ガイド機構３５は、図示しないガイド－ローラ等の支持部材を備え、支持部材がフレーム２１１の側面に接触するように配置されている。洗浄装置１００は、ガイド機構３５により、設置基準面Gに対して傾斜している太陽電池モジュール２１０からの脱落・落下が防止され、かつ、太陽電池モジュール２１０の上下端に沿って直線的に進行する際の安定性が高められる。 The guide mechanism 35 includes a support member such as a guide-roller (not shown), and is arranged so that the support member contacts the side surface of the frame 211. The cleaning device 100 is prevented from dropping or dropping from the solar cell module 210 inclined with respect to the installation reference plane G by the guide mechanism 35, and proceeds linearly along the upper and lower ends of the solar cell module 210. The stability when doing so is improved.
　ブレード２０は、ブレード２０のエッジが太陽電池モジュール２１０の表面に平行に押し当てられるように配置されている。また、ブレード２０は、図４に示すように、太陽電池モジュール２１０の平面の法線方向から洗浄装置１００の進行方向に３０～４５°程度傾いて固定されている。ブレードを傾けて固定する理由は、太陽電池モジュール２１０の洗浄に使用する水の拭き払い性を高くするためである。 The blade 20 is arranged so that the edge of the blade 20 is pressed in parallel with the surface of the solar cell module 210. Further, as shown in FIG. 4, the blade 20 is fixed with an inclination of about 30 to 45 ° from the normal direction of the plane of the solar cell module 210 to the traveling direction of the cleaning device 100. The reason for tilting and fixing the blade is to increase the wiping property of water used for cleaning the solar cell module 210.
　ブレード２０の材料は、水、汚れの拭き取り性能および耐候性を考慮し、弾性のある材料（弾性部材）を用いるのが好ましい。例えば、ブレード２０として、ＥＰＴゴム、ウレタンゴムなどを用いたゴムブレードを用いることが好ましい。 The material of the blade 20 is preferably an elastic material (elastic member) in consideration of water and dirt wiping performance and weather resistance. For example, a rubber blade using EPT rubber, urethane rubber or the like is preferably used as the blade 20.
　ブレード２０は保持部材４０に支持されており、洗浄装置１００と共にＸ方向に進行する。ブレード２０の延びる方向は、図３に示すように、洗浄装置１００の進行方向と垂直なＹ方向に対し、わずかに傾斜していることが望ましい。本実施形態ではブレード２０の延びる方向は、Ｙ方向に対して１～５°程度傾いている。なお、ブレード２０の傾斜方向はＹ方向に対してどちら側でもよい。 The blade 20 is supported by the holding member 40 and proceeds with the cleaning device 100 in the X direction. The extending direction of the blade 20 is desirably slightly inclined with respect to the Y direction perpendicular to the traveling direction of the cleaning apparatus 100 as shown in FIG. In the present embodiment, the extending direction of the blade 20 is inclined by about 1 to 5 ° with respect to the Y direction. Note that the inclination direction of the blade 20 may be on either side with respect to the Y direction.
　これにより、洗浄装置１００が進行する際、ブレード２０が拭き取る太陽電池モジュール２１０の表面の汚水をブレード２０の傾斜方向に押し出す力が働き、太陽電池モジュール２１０の表面から汚水をスムーズに排出することができる。 As a result, when the cleaning apparatus 100 proceeds, the force that pushes out the sewage on the surface of the solar cell module 210 wiped off by the blade 20 in the inclination direction of the blade 20 works, and the sewage can be smoothly discharged from the surface of the solar cell module 210. it can.
　また、ブレード２０をわずかに傾けることで、ブレード２０が太陽電池モジュール２１０の周囲の固定部材２２０の段差を乗り越える際、先に当たった箇所から徐々に乗り越えるようになるため、乗り越え時の負荷を大幅に低減することができる。 In addition, by slightly tilting the blade 20, when the blade 20 climbs over the steps of the fixing member 220 around the solar cell module 210, the blade 20 gradually climbs from the point where it hits first. Can be reduced.
　なお、ブレード２０の傾きが１～５°とわずかな量となっているのは、傾きが大きくなるほど、ブレード２０を収納する保持部材４０の幅が増大し、洗浄装置１００が不必要に大型になるためである。 Note that the inclination of the blade 20 is a slight amount of 1 to 5 ° because the width of the holding member 40 that houses the blade 20 increases as the inclination increases, and the cleaning device 100 becomes unnecessarily large. It is to become.
　太陽電池モジュール２１０の表面に水等の洗浄液を吐出するノズル１０は、保持部材４０に支持された配管１３の所定位置に取り付けられている。図３に示す配管１３は、ブレード２０と同様にＹ方向に対して傾斜しているが、洗浄液がブレード２０に均等に行き渡る配置であれば傾斜していなくてもよい。 The nozzle 10 that discharges cleaning liquid such as water onto the surface of the solar cell module 210 is attached to a predetermined position of the pipe 13 supported by the holding member 40. The pipe 13 shown in FIG. 3 is inclined with respect to the Y direction in the same manner as the blade 20, but may not be inclined as long as the cleaning liquid is evenly distributed to the blade 20.
　この配管１３は、保持部材４０に取り付けられたタンク１１及びポンプ１２に対してホース１４等により接続されている。洗浄装置１００は、タンク１１に蓄えられた洗浄液をポンプ１２で配管１３に流し込み、ノズル１０を経て太陽電池モジュール２１０上に洗浄液を吐出する。 The pipe 13 is connected to the tank 11 and the pump 12 attached to the holding member 40 by a hose 14 or the like. The cleaning apparatus 100 causes the cleaning liquid stored in the tank 11 to flow into the pipe 13 with the pump 12, and discharges the cleaning liquid onto the solar cell module 210 through the nozzle 10.
　なお、タンク１１及びポンプ１２を洗浄装置１００に搭載せずに、メガソーラー発電所内の所定箇所に設置してもよく、この場合は、巻き取りリールに収容された長尺ホース１４を用いて、タンク１１及びポンプ１２を洗浄装置１００の配管１３に接続すればよい。 The tank 11 and the pump 12 may be installed at a predetermined location in the mega solar power plant without being mounted on the cleaning device 100. In this case, using the long hose 14 accommodated in the take-up reel, What is necessary is just to connect the tank 11 and the pump 12 to the piping 13 of the washing | cleaning apparatus 100. FIG.
　タンク１１及びポンプ１２を洗浄装置１００に搭載せずに、メガソーラー発電所内の所定箇所に設置することにより、洗浄装置１００を軽量化することができ、太陽電池モジュール２１０に掛かる負担を低減することができる。また、メガソーラー発電所内に大型のタンク１１を設置することにより、並置された多数の太陽電池モジュール２１０を連続して洗浄することができる。 By installing the tank 11 and the pump 12 at a predetermined location in the mega solar power plant without mounting the cleaning device 100 on the cleaning device 100, the cleaning device 100 can be reduced in weight and the burden on the solar cell module 210 can be reduced. Can do. Further, by installing the large tank 11 in the mega solar power plant, it is possible to continuously wash a large number of the solar cell modules 210 arranged in parallel.
　また、本実施形態では洗浄液を勢いよく吐出して太陽電池モジュール２１０上の汚れを浮かせるために配管１３にノズル１０を取り付けているが、配管１３に直接、吐出口となる穴を開けてノズル１０として用いても良い。 Further, in this embodiment, the nozzle 10 is attached to the pipe 13 in order to eject the cleaning liquid vigorously and lift the dirt on the solar cell module 210. However, the nozzle 10 is directly provided with a hole serving as a discharge port. It may be used as
　本実施形態の洗浄装置１００では、バッテリー２５からポンプ１２とモータ３１に給電することで動作するが、外部電源を用いてポンプ１２とモータ３１に直接給電してもよい。外部電源からポンプ１２及びモータ３１に直接給電する場合は、電源コードを洗浄装置１００から外部電源に配線する必要がある。このような場合、太陽電池モジュール２１０ならびにその周辺にある障害物に電源コードが引っかかり、洗浄装置１００の駆動を妨げる恐れがあるため、バッテリー２５を搭載することが好ましいといえる。 The cleaning apparatus 100 according to the present embodiment operates by supplying power from the battery 25 to the pump 12 and the motor 31. However, the pump 12 and the motor 31 may be directly supplied using an external power source. When power is directly supplied to the pump 12 and the motor 31 from an external power source, it is necessary to wire the power cord from the cleaning device 100 to the external power source. In such a case, it can be said that it is preferable to mount the battery 25 because the power cord may be caught on the solar cell module 210 and obstacles around the solar cell module 210 and the driving of the cleaning device 100 may be hindered.
　洗浄装置１００の全ての構成要素は、直接又は間接的に保持部材４０に固定されている。保持部材４０は、洗浄装置１００が屋外で使用され、さらに洗浄液を使用しての洗浄を行うことから、耐候性に優れた材料で構成されることが好ましい。また、洗浄装置１００の保持部材４０は、太陽電池モジュール２１０の長手方向を覆う形状であり、洗浄装置１００のサイズはユニット連結数により長いもので数ｍになることから、保持部材４０には高剛性・低重量であることが求められる。本実施形態では保持部材４０には軽量で防錆性に優れた金属部材であるアルミニウム部材を用い、トラス構造などの剛性に優れたフレーム構造とすることにより、軽量化を図っている。 All the components of the cleaning apparatus 100 are fixed to the holding member 40 directly or indirectly. The holding member 40 is preferably made of a material having excellent weather resistance since the cleaning apparatus 100 is used outdoors and cleaning is performed using a cleaning liquid. In addition, the holding member 40 of the cleaning device 100 has a shape that covers the longitudinal direction of the solar cell module 210, and the size of the cleaning device 100 is several meters, which is longer depending on the number of unit connections.・ Low weight is required. In this embodiment, the holding member 40 is an aluminum member that is a metal member that is lightweight and excellent in rust prevention, and is made light in weight by forming a frame structure that is excellent in rigidity such as a truss structure.
　以下、本実施形態に係る洗浄装置１００の特徴部となるノズル１０の配置について説明する。 Hereinafter, the arrangement of the nozzles 10 as the characteristic part of the cleaning apparatus 100 according to the present embodiment will be described.
　本実施形態に係る洗浄装置１００では、少なくとも１つのノズル１０が固定部材２２０上を通過するように配管１３に設けられている。この理由について、図３を用いて説明する。 In the cleaning apparatus 100 according to the present embodiment, at least one nozzle 10 is provided in the pipe 13 so as to pass over the fixed member 220. The reason for this will be described with reference to FIG.
　洗浄装置１００は、太陽電池モジュール２１０上を進行方向（Ｘ方向）に走行しながら、配管１３に設けたノズル１０から太陽電池モジュール２１０の表面、または、ブレード２０に向けて洗浄液を吹き付ける。そして、太陽電池モジュール２１０の表面から洗浄液がブレード２０のエッジに掻き集められることにより、受光面が洗浄される。 The cleaning apparatus 100 sprays a cleaning solution from the nozzle 10 provided on the pipe 13 toward the surface of the solar cell module 210 or the blade 20 while traveling on the solar cell module 210 in the traveling direction (X direction). Then, the light receiving surface is cleaned by scraping the cleaning liquid from the surface of the solar cell module 210 to the edge of the blade 20.
　しかし、洗浄装置１００が太陽電池モジュール２１０の固定部材２２０を通過する際は、ブレード２０が固定部材２２０である金具２２１やボルト２２２の突部に乗り上げて、ブレード２０と太陽電池モジュール２１０の表面との間に隙間が生じることにより、この隙間からブレード２０の後方に洗浄液が漏洩する。 However, when the cleaning apparatus 100 passes through the fixing member 220 of the solar cell module 210, the blade 20 rides on the protrusions of the metal fitting 221 and the bolt 222 that are the fixing member 220, and the blade 20 and the surface of the solar cell module 210 As a result, a cleaning liquid leaks behind the blade 20 from the gap.
　また、固定部材２２０の位置がノズル１０の位置若しくはノズル１０からの水供給位置より傾斜上流側であると、ブレード２０と固定部材２２０の隙間から洗浄液が漏洩した後、上流側で供給された洗浄液が流れ落ちてくるまでの間、洗浄液が不足した状態が継続する。 When the position of the fixing member 220 is on the upstream side of the nozzle 10 or the position where water is supplied from the nozzle 10, the cleaning liquid leaked from the gap between the blade 20 and the fixing member 220 and then supplied on the upstream side. Until the liquid flows down, the state where the cleaning liquid is insufficient continues.
　このため、固定部材２２０上をノズル１０が通過しない場合、固定部材２２０の前方に溜まる洗浄液が不足して洗浄力が低下する問題が生じる。 For this reason, when the nozzle 10 does not pass over the fixing member 220, there arises a problem that the cleaning liquid that collects in front of the fixing member 220 is insufficient and the cleaning power is reduced.
　これに対して、本実施形態に係る洗浄装置１００では、固定部材２２０上を通過するようにノズル１０が配管１３に設けられているため、ブレード２０が固定部材２２０に乗り上げて、隙間からブレード２０の後方に洗浄液が漏洩しても、固定部材２２０の前方に常に洗浄液が供給され続けるので、洗浄力の低下を防止することができる。 On the other hand, in the cleaning apparatus 100 according to the present embodiment, the nozzle 10 is provided in the pipe 13 so as to pass over the fixing member 220, so that the blade 20 rides on the fixing member 220 and passes through the gap from the blade 20. Even if the cleaning liquid leaks behind, the cleaning liquid is always supplied to the front of the fixing member 220, so that the cleaning power can be prevented from being lowered.
　本実施形態に係る洗浄装置１００では、固定部材２２０が設置された箇所に合わせて２つのノズル１０を設けているが、ノズル１０は固定部材２２０の箇所以外にも複数設けてもよい。ノズル１０の吐出量については、ポンプ１２の最大圧力・最大流量や、洗浄装置１００の進行速度によって最適な値が異なることから、ポンプ１２及びモータ３１の性能から必要量を算出すると良い。 In the cleaning apparatus 100 according to the present embodiment, the two nozzles 10 are provided in accordance with the location where the fixing member 220 is installed, but a plurality of nozzles 10 may be provided in addition to the location of the fixing member 220. As for the discharge amount of the nozzle 10, the optimum value varies depending on the maximum pressure / maximum flow rate of the pump 12 and the traveling speed of the cleaning device 100, and therefore, the required amount may be calculated from the performance of the pump 12 and the motor 31.

FIG. 5 is a plan view showing the solar cell module 210 row to be cleaned and the cleaning device 100 according to the second embodiment installed on the solar cell module 210. FIG. 6 is a side view showing the cleaning apparatus 100 according to the second embodiment. In FIG. 6, some components such as the guide mechanism 35 are omitted.
　以下、本発明の第２の実施形態に係る洗浄装置１００ついて詳細に説明する。本実施形態では、前述の洗浄装置１００の構成要素に、位置検出部５０と流量制御部６０を追加した構成となっている。なお、本実施形態に係る洗浄装置１００では、位置検出部５０と流量制御部６０以外の構成要素については、実施形態１と同様であるため、説明を省略する。 Hereinafter, the cleaning apparatus 100 according to the second embodiment of the present invention will be described in detail. In the present embodiment, the position detection unit 50 and the flow rate control unit 60 are added to the components of the cleaning device 100 described above. In the cleaning apparatus 100 according to the present embodiment, the components other than the position detection unit 50 and the flow rate control unit 60 are the same as those in the first embodiment, and thus the description thereof is omitted.
　位置検出部５０は、固定部材２２０の位置を検出するためのものであり、赤外線センサや撮像素子によって構成されている。洗浄装置１００は、例えば、図５に示すように、位置検出部５０として赤外線センサを保持部材４０に取り付けることにより、隣り合う太陽電池モジュール２１０間の隙間を検出して、固定部材２２０の位置として判断することができる。 The position detection unit 50 is for detecting the position of the fixing member 220, and is configured by an infrared sensor or an image sensor. For example, as illustrated in FIG. 5, the cleaning apparatus 100 attaches an infrared sensor as the position detection unit 50 to the holding member 40 to detect a gap between the adjacent solar cell modules 210, and sets the position as the position of the fixing member 220. Judgment can be made.
　また、洗浄装置１００は、位置検出部５０としてカメラ等の撮像素子をノズル１０の近傍に設置することにより、固定部材２２０を光学的に検出できるようにしてもよい。いずれの場合も、位置検出部５０を洗浄装置１００の進行方向の前方位置に設けて、ブレード２０が固定部材２２０に到達する前に固定部材２２０の有無を検出する必要がある。 Further, the cleaning apparatus 100 may be configured to optically detect the fixing member 220 by installing an image sensor such as a camera in the vicinity of the nozzle 10 as the position detection unit 50. In any case, it is necessary to provide the position detection unit 50 at a front position in the traveling direction of the cleaning device 100 and detect the presence or absence of the fixing member 220 before the blade 20 reaches the fixing member 220.
　流量制御部６０は、タンク１１から洗浄液を汲み上げるポンプ１２を制御し、ノズル１０から吐出される洗浄液の流量を可変させるものである。 The flow rate control unit 60 controls the pump 12 that pumps the cleaning liquid from the tank 11 and varies the flow rate of the cleaning liquid discharged from the nozzle 10.
　第２の実施形態に係る洗浄装置１００では、位置検出部５０により洗浄装置１００の前方に固定部材２２０が近づいたことを検知すると、流量制御部６０によりポンプ１２を制御して、ブレード２０が固定部材２２０上を通過するタイミングでノズル１０が吐出する洗浄液の流量を増加させている。 In the cleaning apparatus 100 according to the second embodiment, when the position detection unit 50 detects that the fixing member 220 has approached the front of the cleaning apparatus 100, the flow rate control unit 60 controls the pump 12 to fix the blade 20. The flow rate of the cleaning liquid discharged from the nozzle 10 is increased at the timing of passing over the member 220.
　これにより、ブレード２０が固定部材２２０に乗り上げて、ブレード２０の後方に洗浄液が漏れ出しても、固定部材２２０の前方に吐出される洗浄液が増加するので、洗浄力の低下を防止することができる。 As a result, even if the blade 20 rides on the fixing member 220 and the cleaning liquid leaks behind the blade 20, the cleaning liquid discharged to the front of the fixing member 220 increases, so that it is possible to prevent the cleaning power from being lowered. .
　図７は、第２の実施形態に係る洗浄装置１００の変形例を示す平面図である。変形例の洗浄装置１００では、ノズル１０の個数を増やして、よりきめ細かく制御を行うことにより、さらなる節水を行うものである。なお、変形例に係る洗浄装置１００では、ノズル１０以外の構成要素については、実施形態２と同様であるため、説明を省略する。 FIG. 7 is a plan view showing a modification of the cleaning apparatus 100 according to the second embodiment. In the cleaning apparatus 100 according to the modified example, the number of nozzles 10 is increased and finer control is performed to further save water. In the cleaning apparatus 100 according to the modification, the components other than the nozzle 10 are the same as those in the second embodiment, and thus the description thereof is omitted.
　図７に示す変形例の洗浄装置１００では、連続的に洗浄液を吐出する第１ノズル１０Ａと、電磁バルブ等と組合されて間欠的に洗浄液を吐出する第２ノズル１０Ｂを備えている。第１ノズル１０Ａは、太陽電池モジュール２１０のＹ方向全体に均等に洗浄液を吐出するように、配管１３に略等間隔で設けられている。第２ノズル１０Ｂは、上述した各実施形態の洗浄装置１００と同様に、固定部材２２０上を通過するように配管１３に設けられている。 7 includes a first nozzle 10A that continuously discharges a cleaning liquid, and a second nozzle 10B that discharges the cleaning liquid intermittently in combination with an electromagnetic valve or the like. The first nozzles 10 </ b> A are provided in the pipe 13 at substantially equal intervals so as to discharge the cleaning liquid evenly over the entire Y direction of the solar cell module 210. The 2nd nozzle 10B is provided in the piping 13 so that the fixed member 220 may be passed similarly to the washing | cleaning apparatus 100 of each embodiment mentioned above.
　変形例の洗浄装置１００では、第１ノズル１０Ａと第２ノズル１０Ｂの合計６個のノズル１０が設けられているが、第１ノズル１０Ａ、第２ノズル１０Ｂのそれぞれから吐出される洗浄液は、洗浄に必要な最小限の流量に抑えられるため、洗浄液の節水効果が得られる。なお、変形例では、流量制御部６０は、第２ノズル１０Ｂに設けられた電磁バルブの開閉を制御するように構成されている。 In the cleaning apparatus 100 according to the modified example, a total of six nozzles 10 including the first nozzle 10A and the second nozzle 10B are provided. The cleaning liquid discharged from each of the first nozzle 10A and the second nozzle 10B is cleaned. Therefore, the water saving effect of the cleaning liquid can be obtained. In the modification, the flow rate control unit 60 is configured to control the opening and closing of the electromagnetic valve provided in the second nozzle 10B.
　具体的には、洗浄装置１００が太陽電池モジュール２１０の固定部材２２０以外を通過するときには、図７の左側に示すように、２つの第２ノズル１０Ｂからは洗浄液の吐出を停止し、４つの第１ノズル１０Ａから洗浄液を吐出する。ここで、複数の第１ノズル１０Ａを設けることにより、各第１ノズル１０Ａによる洗浄領域が個数分だけ細分化されるため、各第１ノズル１０Ａから吐出される洗浄液を必要最小限の流量に最適化することができる。 Specifically, when the cleaning device 100 passes through other than the fixing member 220 of the solar cell module 210, as shown on the left side of FIG. 7, the discharge of the cleaning liquid is stopped from the two second nozzles 10B, and the four second A cleaning liquid is discharged from one nozzle 10A. Here, by providing a plurality of first nozzles 10A, the cleaning area by each first nozzle 10A is subdivided by the number, so the cleaning liquid discharged from each first nozzle 10A is optimal for the minimum necessary flow rate. Can be
　洗浄装置１００のブレード２０が太陽電池モジュール２１０の固定部材２２０上を通過するタイミングでは、図７の右側に示すように、固定部材２２０上を通過するように設けられた２つの第２ノズル１０Ｂから洗浄液を吐出して、ブレード２０後方に漏洩する分の洗浄液を補っている。このように、固定部材２２０上を通過する第２ノズル１０Ｂは必要に応じて洗浄液を吐出するように制御されるため、太陽電池モジュール２１０列をＸ方向全体に洗浄する場合に、その洗浄液の使用量を最小限に低減することができる。 At the timing when the blade 20 of the cleaning device 100 passes over the fixing member 220 of the solar cell module 210, as shown on the right side of FIG. 7, from the two second nozzles 10 </ b> B provided to pass over the fixing member 220. The cleaning liquid is discharged to compensate for the amount of cleaning liquid that leaks behind the blade 20. As described above, since the second nozzle 10B passing over the fixed member 220 is controlled to discharge the cleaning liquid as necessary, the cleaning liquid is used when cleaning the solar cell module 210 rows in the entire X direction. The amount can be reduced to a minimum.
　〔実施形態３〕

FIG. 8 is a plan view showing the solar cell module 210 row to be cleaned and the cleaning device 100 according to the third embodiment installed therein. FIG. 9 is a side view showing the cleaning apparatus 100 according to the third embodiment. In FIG. 9, some components such as the guide mechanism 35 are omitted.
　以下、本発明の第３の実施形態に係る洗浄装置１００について詳細に説明する。第３の実施形態に係る洗浄装置１００では、ブレード２０が主ブレード２０Ａと補助ブレード２０Ｂの２枚で構成されている。なお、本実施形態に係る洗浄装置１００は、ブレード２０を主ブレード２０Ａと補助ブレード２０Ｂの２枚で構成した以外の構成要素については、実施形態１と同様であるため、説明を省略する。 Hereinafter, the cleaning apparatus 100 according to the third embodiment of the present invention will be described in detail. In the cleaning apparatus 100 according to the third embodiment, the blade 20 is composed of two blades, a main blade 20A and an auxiliary blade 20B. In the cleaning apparatus 100 according to the present embodiment, the constituent elements other than the blade 20 including the main blade 20A and the auxiliary blade 20B are the same as those in the first embodiment, and thus the description thereof is omitted.
　第３の実施形態に係る洗浄装置１００の主ブレード２０Ａと補助ブレード２０Ｂは、それぞれ上述した各実施形態のブレード２０と同様に構成されており、主ブレード２０Ａは上述した各実施形態のブレード２０と同じ位置に配置され、補助ブレード２０Ｂは主ブレード２０Ａの後方に所定の間隔を空けて配置されている。この主ブレード２０Ａと補助ブレード２０Ｂの間隔は固定部材２２０を跨げる距離に設定されている。 The main blade 20A and the auxiliary blade 20B of the cleaning device 100 according to the third embodiment are configured similarly to the blade 20 of each embodiment described above, and the main blade 20A is the same as the blade 20 of each embodiment described above. Arranged at the same position, the auxiliary blade 20B is arranged behind the main blade 20A at a predetermined interval. The distance between the main blade 20A and the auxiliary blade 20B is set to a distance over the fixing member 220.
　上述した各実施形態の洗浄装置１００では、ブレード２０が固定部材２２０上を乗り上げるとき、洗浄液がブレード２０の後方に漏洩することを説明したが、この洗浄液に汚れが混ざり染みとなって太陽電池モジュール２１０の表面に残留する場合がある。 In the cleaning apparatus 100 of each embodiment described above, it has been described that when the blade 20 rides on the fixing member 220, the cleaning liquid leaks to the rear of the blade 20. However, the cleaning liquid is contaminated with stains and becomes a solar cell module. It may remain on the surface of 210.
　第３の実施形態に係る洗浄装置１００によれば、主ブレード２０Ａと補助ブレード２０Ｂが同時に固定部材２２０を乗り上げない配置となっており、図８および図９に示すように、主ブレード２０Ａにより払拭されず、固定部材２２０の箇所から主ブレード２０Ａの後方に漏洩した洗浄液は、補助ブレード２０Ｂによって払拭される。 According to the cleaning device 100 according to the third embodiment, the main blade 20A and the auxiliary blade 20B are arranged so as not to run over the fixing member 220 at the same time, and are wiped by the main blade 20A as shown in FIGS. Instead, the cleaning liquid leaked from the location of the fixing member 220 to the rear of the main blade 20A is wiped by the auxiliary blade 20B.
　このとき、漏洩した洗浄液は、太陽電池モジュール２１０の傾斜によって固定部材２２０の位置から低位置側に向かって流れるため、補助ブレード２０Ｂが固定部材２２０を乗り上げたときに補助ブレード２０Ｂの後方に洗浄液が漏洩することがない。このため、洗浄液の漏洩による太陽電池モジュール２１０の汚れ染みを防止することができる。 At this time, since the leaked cleaning liquid flows from the position of the fixing member 220 toward the low position side due to the inclination of the solar cell module 210, the cleaning liquid is behind the auxiliary blade 20B when the auxiliary blade 20B rides on the fixing member 220. There is no leakage. For this reason, the stain of the solar cell module 210 due to the leakage of the cleaning liquid can be prevented.
　上記実施形態を用いて具体的に説明を行ったが、本発明はそれらに限定されるものではない。上述した３つの実施形態にそれぞれ開示された技術的手段を適宜組み合わせて得られる実施形態についても本発明の技術的範囲に含まれる。 Although specific description has been given using the above embodiment, the present invention is not limited thereto. Embodiments obtained by appropriately combining the technical means disclosed in the above-described three embodiments are also included in the technical scope of the present invention.
　また、上述の洗浄装置は、太陽光発電装置に限らず、同一幅で長く伸びる被洗浄面に対して好適に適用することができる。例えば、上述の洗浄装置を、一般家庭の屋根、および廊下に適合させることも可能である。 Further, the above-described cleaning device is not limited to the solar power generation device, and can be suitably applied to a surface to be cleaned that extends long with the same width. For example, it is possible to adapt the above-described cleaning device to the roofs and corridors of ordinary homes.
　以上説明してきた通り、本発明の洗浄装置は、互いに固定部材で連結された複数のパネルの被洗浄面を自走しながら洗浄する洗浄装置であって、被洗浄面上を移動するための移動部と、固定部材上を通過するように移動部に配置され、被洗浄面に向けて洗浄液を吐出するノズルと、被洗浄面上に押し当てて洗浄液を払拭するブレードとを備えることを特徴とする。このような構成とすることによって、列状に連結されたパネル群を連結部の突部に影響されることなく、少量の洗浄液で洗浄することができる洗浄装置を提供することができる。 As described above, the cleaning device of the present invention is a cleaning device that cleans while cleaning the surfaces to be cleaned of a plurality of panels connected to each other by a fixing member, and moves for moving on the surface to be cleaned.
