Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation panels, in particular to a drainage mechanism for a photovoltaic power generation panel. Background Art

[0002] Photovoltaic panels are devices used to collect light sources and convert them into electrical energy. After the photovoltaic panels are installed, in order to avoid the accumulation of rainwater on the surface of the photovoltaic panels and the reduction of lighting efficiency, it is necessary to use a drainage mechanism to block and clean the rainwater. The existing drainage mechanism usually sets a rain shield on the top of the photovoltaic panel to block the rainwater, thereby reducing the probability of rainwater accumulation on the surface of the photovoltaic panel.

The utility model is a photovoltaic panel drainage mechanism with a simple and compact structure, low cost and easy operation, more flexible and convenient use, and suitable for being widely promoted and used.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned photovoltaic panel drainage mechanism has the following problems: the device adjusts the distance between the water guide block and the positioning block to limit the photovoltaic panels of different models, and prevents rainwater from falling on the photovoltaic panels through the water guide block. In order to improve the lighting efficiency, the photovoltaic panels are usually tilted, so that the water guide block can only block part of the photovoltaic panel body, and rainwater will still fall on the surface of the photovoltaic panel. When rainwater falls on the photovoltaic panel, it is easy to accumulate rainwater in the gap between the bottom of the photovoltaic panel and the positioning block, thereby making the device have a low drainage efficiency for the photovoltaic panel. In view of this, a photovoltaic panel drainage mechanism is provided to overcome the above-mentioned defects. Utility Model Content
