Background

The green roofing system technology is an important component of the green building technology, and the green building roofing system has the functions of energy conservation, environmental protection, ecology, recycling, service life prolonging and coexistence with nature in harmony. Green roofing systems come in a variety of forms, such as single-layer coiled roofing systems, planted roofing systems, photovoltaic building-roofing systems, and the like. It is now relatively common to provide photovoltaic building roofing forms, i.e. photovoltaic systems arranged on the roofs of buildings, which have the following advantages: the photovoltaic array is generally arranged on an idle roof, so that the photovoltaic array does not occupy the land; in summer with peak electricity consumption, which is also the period with the maximum sunshine amount and the maximum power generation amount of the photovoltaic system, the peak-shaving effect can be achieved on the power grid; the distributed grid-connected photovoltaic system is adopted, a storage battery is not required to be arranged, so that investment is saved, the limitation of the pollution environment of the storage battery is avoided, and the building can fully digest the power generated by the photovoltaic system; the photovoltaic array absorbs solar energy to be converted into electric energy, so that the outdoor comprehensive temperature is greatly reduced, the heat transfer of a roof and the cold load of an indoor air conditioner are reduced, and the building energy-saving effect can be achieved.

The current photovoltaic roofing form is still relatively single, generally install photovoltaic system on the roof, its structural style can refer to fig. 1, it can be seen that current photovoltaic support does not normally possess the function of collecting the rainwater, the rainwater that falls on the photovoltaic face can only flow down along the photovoltaic board, direct discharge gets into sewer system, cause the wasting of resources, partial photovoltaic support only can carry out rough collection to the rainwater, and the photovoltaic board is leaked outside, dust, rubbish impurity such as bird's droppings fall on its surface easily, this kind of simple mode of converging can't get rid of the photovoltaic board and is carried in the rainwater after being erodeed by the rainwater, in addition, the rainwater after the initial stage rainwater also can't abandon the stream, lead to the rainwater after converging to be dirty, the purifying pressure after the rainwater is collected is great.

By combining the pain points, how to optimize the existing photovoltaic roof, so that the photovoltaic roof forms a green roof system which integrates the functions of photovoltaic power generation, rainwater collection, roof planting and the like, and has the advantages of energy conservation, environmental protection, ecology, recycling, service life prolongation and natural harmony and coexistence, and needs further research.

In the initial state, since no rainwater exists in the collecting box 4, the whole weight is light, and at this time, the filter plates 46 are completely built in the collecting box 4; the sealing plug 561 is not inserted into the drainage port 431, and at this time, the drainage port 431 is opened; when the solar energy collector is not raining at ordinary times, some garbage 461 such as leaves, paper sheets and the like can slide down the inclined plane of the photovoltaic panel 32 to the filter plate 46 when falling to the surface of the photovoltaic panel 32, and can roll down the inclined plane of the filter plate 46 to the lower end of the filter plate 46 for aggregation.

When rainwater flows down, the initial rainwater flows through the surface of the photovoltaic panel 32, and the cloudy initial rainwater formed by flushing the photovoltaic panel 32 and carrying dust and other impurities flows onto the guide plate 44 through the filter plate 46, stays at the drainage port 431 through the first filter hole 452 and flows into the first space 422 through the drainage port 431; as the rainwater collected in the first space 422 increases, the whole weight becomes heavier, the collecting box 4 integrally presses down the upper cylinder 52, the upper cylinder 52 moves downwards to drive the inclined block I54I to move downwards, the inclined block I54I can squeeze the inclined block I54 in the moving process, the inclined rod 541 is further driven to move, the inclined rod 541 can drive the lifting rod 56 to move upwards when moving, the spring 58 is further compressed, the lifting rod 56 drives the filter plate 46 to move upwards after moving upwards, so that the filter plate 46 moves out of the collecting box 4, and at the moment, the lowest end of the filter plate 46 is positioned above the collecting box 4; in this process, the sealing plug 561 moves up along with the lifting rod 56, and the sealing plug 561 will seal the drainage port 431 to the column, and the dirty initial rainwater is collected in the first space 422; then, the structures of the photovoltaic panel 32, the filter plate 46 and the like are all washed clean, along with the continuous raining, relatively clean middle-stage and later-stage rainwater can flow onto the guide plate 44 through the photovoltaic panel 32, the sealing plug 561 is used for sealing the post by the abandoned flow port 431, at the moment, more and more rainwater above the guide plate 44 can accumulate, and when the rainwater reaches the position of the guide hole 441, the rainwater can flow into the second space 423 through the guide hole 441, so that the collection of relatively clean middle-stage and later-stage rainwater is completed.

In this process, after the filter plate 46 is removed from the collecting box 4, the garbage 461 on the filter plate 46 can smoothly self-drop into the arc-shaped groove bucket 47 to be collected under the flushing of rainwater, and the arc-shaped groove bucket 47 can be cleaned manually at regular intervals when no rain falls in the later period, so that the process is very convenient.

When it is desired to irrigate plants in the planting box 6, the rainwater collected in the second space 423 may be preferentially used, saving water resources.
