Description

Water drop member

The present invention relates to a water droplet removing member used by being attached to a frame of a photovoltaic power generation panel that photoelectrically converts sunlight.

Solar power generation panels are placed on vacant lots such as mountains and abandoned cultivated land and idle land, and are often installed on the rooftops of buildings and roofs of houses. For example, as a method of installing a photovoltaic power generation panel on a flat roof such as the roof of a building, a method of fixing a support stand to the surface of the flat roof with an anchor or the like and attaching the photovoltaic power generation panel to the support mount using a mounting bracket is generally used. It is a target. Further, when the photovoltaic power generation panel is installed on a roof other than the flat roof, the photovoltaic power generation panel is attached to the roof via a support pedestal or a support member attached to the roof material.

If the photovoltaic power generation panel is attached to the roof, when it rains, the rain that has fallen on the photovoltaic power generation panel flows on the surface of the panel and falls over the frame to the surface of the roofing material. Rainwater tends to drip intensively from the corners of the frame to a specific part of the roofing material surface, and if the roofing material is a metal folded plate, rust may occur at that specific part. Not a few. In order to prevent the metal roof from being rusted in this way, for example, in Patent Document 1, a rust preventive protective layer is provided on the installation surface of the photovoltaic power generation panel of the metal roofing material fixed on the roof. Is disclosed. Further, Patent Document 2 discloses a technique of partially covering a position under water of a metal roof surface with a metal having a higher ionization tendency than that of a metal roof.

In addition, a plurality of spiral grooves 221 are formed from the central portion toward the outer end portion on the surface receiving the water dripping from the solar power generation panel P of the water turbine unit 20, so that the water is concentrated from the solar power generation panel P. The water (rainwater) that has been dropped is efficiently caused by flowing down along the spiral groove 221 on the surface of the turbine portion 20 to give the turbine portion 20 the momentum to rotate horizontally and to strengthen the momentum of the rotation of the turbine portion 20. Water can be blown around.

Further, in the case of the connecting portion 30 configured as described above, the connecting portion 30 swingably suspends the turbine portion 20 with respect to the mounting portion 10, and the water turbine portion 20 is intensively dropped from the photovoltaic power generation panel P. The movement of the water turbine unit 20 brought about by the water that has been generated is not restricted, and the water turbine unit 20 can more efficiently disperse and disperse the water to the surroundings.

Although the present invention has been described above with reference to the drawings, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above embodiment, the water wheel portion of the water droplet removing member of the present invention is formed in a substantially conical shape, but the present invention is not limited to this, and even a flat water wheel portion can be attached to the mounting portion. By eccentricizing the mounting position from the center, it is possible to horizontally rotate the turbine portion by the force of water (rainwater) that is concentratedly dropped from the solar power generation panel, and a corresponding effect is achieved.

Further, in the above embodiment, the water droplet removing member is configured to be attached to the frame of the solar panel by a clip-shaped mounting portion, but the present invention is not limited to this, and the water droplet removing member is attached by a method such as adhesion or crimping. The portion may be attached to the frame, or the mounting portion may be attached to the frame by using a clamp, a bolt, or the like.
