Description

Solar photovoltaic panel damp spot prevention guiding device

Technical Field

The utility model relates to a solar photovoltaic power generation device especially relates to a various steel tile roof photovoltaic power generation device.

Background

As shown in fig. 1, the photovoltaic panel 1 on the photovoltaic power station sets a light-facing angle according to the different latitudes of the area where the power station is located, when the framed photovoltaic panel meets the rainy day, most rainwater is discharged out of the photovoltaic panel under the action of gravity, but due to the blocking of the lower frame 10, a small amount of rainwater is accumulated at the lower part of the framed photovoltaic panel, so that irregular wet spots 11 are formed. Particularly, on a photovoltaic power station with a color steel tile roof, due to the fact that the incident angle of the photovoltaic panel is small, more rainwater is accumulated, and the phenomenon of wet spots is more obvious. After long-term use, the wet spots are combined with floating dust in the air to form dust and dirt to shield sunlight, so that the power generation efficiency of the photovoltaic panel is reduced, and the service life of the photovoltaic panel is prolonged.

Disclosure of Invention

The utility model aims to solve the technical problem that a solar photovoltaic board damp proof spot guiding device is provided, the formation of damp spot and dirt on can reducing the photovoltaic board is favorable to improving photovoltaic power plant's generating efficiency and photovoltaic board's life.

In order to solve the technical problem, the solar photovoltaic panel moisture spot prevention diversion device comprises a short vertical plate, a long horizontal plate, a long vertical plate and a short horizontal plate which are sequentially bent in the same direction at a right angle, wherein a plurality of diversion grooves are milled and dug in the inner surfaces of the long horizontal plate and the long vertical plate, a plurality of open grooves matched with the diversion grooves are milled and dug in the short vertical plate, and the open grooves are used as drainage ports of the diversion grooves; the diaphragm is provided with a plurality of through-holes matched with the diversion trenches, and the through-holes are used as water outlet holes of the diversion trenches.

The diameter of the diversion trench is set to be 4 +/-0.5 mm.

This guiding device can the lock on solar photovoltaic board frame, and it carries out the drainage through capillary to frame ponding to discharge through the apopore, after raining, can in time eliminate solar photovoltaic board frame position ponding, thereby reduce the formation of wet spot and dirt on the photovoltaic board, be favorable to improving photovoltaic power plant's generating efficiency and photovoltaic board's life.
