2. Description of the Related Art In recent years, interest in alternative energy sources to fossil fuels has been increasing in order to prevent global warming.
2. Description of the Related Art Solar cell panels have been attracting attention for their development as clean new energy sources that do not generate pollution such as exhaust gas from the standpoint of global environmental protection. With regard to solar cell panels, there has been an increasing interest in introducing solar power generation systems to homes because of the performance of materials used, which have little effect on environmental conservation, high energy conversion rates, and stable power generation characteristics. I have. Some homes are equipped with such a system as standard,
In addition to ordinary roofing system for residential use, etc.,
In response to this trend, manufacturers have been working to develop a variety of products, and an environment that is easy to use is being created.

[0003]

The photovoltaic power generation system has been gaining recognition due to social needs such as energy saving performance and environmental measures, and has been used to reduce carbon dioxide emissions even from the global environment. Although connected, when a power generation system is provided in a general house, it is installed outdoors such as a roof. Due to outdoor exposure, rainwater stagnation and dirt tend to adhere or accumulate depending on the installation environment, the transparency of the surface coating material decreases, the incident light reaching the photovoltaic element decreases, and the photovoltaic power decreases. there were. In addition, under the conditions of natural conditions such as rain, snow, wind, etc., the dust is accumulated due to the accumulation of dust, etc. for many years, and not only the appearance is impaired, but also the conversion efficiency and the effect on the power generation efficiency are reduced. Inevitable.

[0004] Maintenance of a system device which is usually installed on the roof inclined surface of a general house of about two floors or integrated with the roof structure is performed in such a manner that the cleaning work is of the same level as indoor cleaning by a vacuum cleaner or the like and the outer surface cleaning of window glass. However, it is difficult to work on high rooftops and dirty roof slopes. Further, in the case of cleaning watering work on a high roof, washing water and washing water containing detergent are scattered, and there is a problem that it affects not only the resident's house but also passersby and nearby plants and laundry. Installation of a photovoltaic power generation system is basically determined by the relationship between equipment costs and utility costs,
There is also a restriction that the cleaning cannot be carried out by removing the roof structure from the installation form of the house roof structure, and the cleaning of the system is inevitably a dangerous work on the roof surface. Further, there is a drawback that the energy conversion rate cannot be reduced due to dust and dirt. In addition to the necessity of cleaning the system installed for a certain period of time, a low cost and efficient cleaning by a specialist is required. There is a strong need for improvements in conjunction with cleaning equipment for work.

The introduction of photovoltaic power generation systems into homes is becoming easier to install, with various subsidies and financing accompanying the expansion of the subsidy system in the country for cost reduction and market independence. Although it has been several years since the last year, it is especially important to maintain
There is a situation that the problem is. 2. Description of the Related Art Conventionally, various proposals have been made as a cleaning device for an outer surface of a building, an automatic outer surface cleaning device, or a cleaning device for a smooth wall or a window glass of a high place such as a building. For example, Japanese Patent Application Laid-Open No. H10-248761 discloses a traversing method in which a cleaning mechanism cleans the outer surface of a building while moving horizontally along a pair of upper and lower guide rails horizontally disposed on the outer surface of the building. A type automatic outer surface cleaning device is disclosed. Japanese Patent Application Laid-Open No. 2000-41904 discloses a cleaner unit for cleaning a high-level smooth wall surface of a building, which includes an adsorption traveling unit that adsorbs and runs on a smooth wall surface and a cleaning unit that sprays water and collects wastewater. A cleaning unit, which is detachable and can be attached to a cleaning unit before and after the suction traveling unit so as to be freely replaceable, that is, a building for inner and outer glass surfaces of a blow-through portion of about 1 to 3 floors. A small suction unit for cleaning dirt on an outer window glass or the like is disclosed. Further, JP-A-11-171
No. 063 discloses that a gondola gauge is movably adsorbed on a vertical wall surface such as an outer wall surface of a building, and is used as a steady rest of a gondola gauge operated by an operator who climbs and descends along the wall surface or moves the wall surface. In addition, a wall suction moving device that can be used for an automatic device that performs cleaning, repair, inspection, and the like on the wall surface has been proposed.

The above-mentioned Japanese Patent Application Laid-Open No. Hei 10-248761 discloses that an automatic outer surface cleaning apparatus which moves vertically to perform a cleaning operation is functional when a cleaning object such as a window is continuous in a vertical direction. If the windows are continuous in the horizontal direction or if there is a wart-like protrusion on each floor, it is difficult to perform the cleaning operation smoothly, so a traversing device has been proposed. This is a proposal that aims to improve the guide rail installation accuracy of the building, which is not high, that the load is applied evenly to the upper and lower guide rails, and that the vehicle may be easily inclined in the traveling direction and difficult to travel. But,
It is characterized by a configuration in which a substantially uniform load is applied to and supported by the upper and lower guide rail members via the upper and lower engaging and moving mechanisms. Also, Japanese Patent Application Laid-Open No. 2000-4190
No. 4 discloses a cleaner unit for cleaning a smooth surface of a building at a high place, that is, scattering of a cleaning agent used in a conventional integrated cleaning device, a small robot, or a long poll type cleaning machine. In addition, it discloses that the labor and cost for installing the apparatus are increased by the treatment or the manual cleaning operation, and that the problems of cleaning wastewater remain even if the cleaning machine is reduced in size and weight. However, the above proposal is a small suction cleaner unit for cleaning dirt on the vertical inner and outer glass surfaces of a building,
Although dust and the like are blown off by the air-injection mechanism, it is a complicated cleaning device such as a load on the cleaning device and a traveling device on an inclined surface. Japanese Unexamined Patent Application Publication No. 11-171063 discloses an automatic apparatus for movably adsorbing to a vertical wall surface such as an outer wall surface of a building, preventing a gondola gage from swaying, and cleaning, repairing and inspecting the wall surface while moving the wall surface. It is a proposal of a wall surface adsorption moving device which can be used for a vehicle. Since the solar panel is installed in a house roof structure with an inclined surface, there is a difference between the vertical wall surface and the inclined surface. Cleaning equipment seems to be effective, but on the other hand, such a type of automatic cleaning equipment increases the weight and complexity of the equipment and increases the cost of manufacturing equipment. However, there still remains a problem that the hanging device for preventing the unexpected fall of the device cannot be dealt with by a simple device. JP 20
In Japanese Patent Publication No. 00-166837, there is disclosed a small-sized suction cleaner unit for cleaning dirt on a window glass surface outside a building for inner and outer glass surfaces of a blow-through portion of about 1 to 3 floors. It is a proposal to solve the difficulty of increasing the size of the cleaning device, the cleaning robot, and the port-type cleaning device integrated with the conventional technology, but this is combined with the difficulty of the suspension mechanism or the mounting and fixing method of the cleaning device. In addition, even when the flow of drainage is present, the phenomenon of lateral escape of drainage on the inclined surface of the solar cell panel is a problem.
