Description

Gas rectifying member for non-fixed photovoltaic panel support frame

The present invention relates to a gas rectifying member used for a photovoltaic power generation panel support stand for supporting a photovoltaic power generation panel that photoelectrically converts sunlight, and is particularly installed on a land roof such as the roof of a building without using an anchor or the like. The present invention relates to a gas rectifying member used for a non-fixed type photovoltaic power generation panel support frame that can be used.

Conventionally, as a method of installing a photovoltaic power generation panel on a flat roof such as the roof of a building, a method of driving an anchor on the surface of the flat roof and fixing a support stand to this anchor is common. However, with this method, the waterproof layer of the flat roof is damaged by the driving of the anchor, and the waterproof function is lost. Therefore, in recent years, the support frame of the photovoltaic power generation panel is placed on the flat roof without using the anchor. Various non-fixed support mounts have been proposed that allow the installation of photovoltaic power generation panels by themselves.

As the support stand of the non-fixed type photovoltaic power generation panel as described above, for example, concrete having an elongated rectangular shape and having an inclined surface configured so as to be located within the range of the back surface of the photovoltaic power generation panel. There are a block pedestal (Patent Document 1) and a support pedestal (Patent Document 2) in which a support column and a support metal fitting for supporting a photovoltaic power generation panel are attached to a concrete base.

However, since the non-fixed type photovoltaic power generation panel support pedestal as described above is not fixed to the land roof by using an anchor, it is formed between the back surface of the photovoltaic power generation panel installed on the support pedestal and the surface of the land roof. When a strong wind invades the space, the photovoltaic power generation panel may come off from the support pedestal and scatter, or the photovoltaic power generation panel may scatter together with the support pedestal, and its wind resistance performance becomes a problem.

It is preferable that the height is such that the wind blowing from the horizontal direction with respect to the power generation panel P can be prevented from entering the space S, and there is a gap between the gas rectifying member 30 and the lower surface of the solar power generation panel P. It is more preferable that the height dimension does not occur, that is, the height dimension of the lower surface of the photovoltaic power generation panel P arranged on the support frame 100 or more. Further, the height dimension h ₃₀ of the gas rectifying member 30 is such that the gas rectifying member 30 can be avoided from being pushed and moved by the wind blowing from the photovoltaic power generation panel P side with respect to the gas rectifying member 30 from the horizontal direction.

The gas rectifying member 30 may have a _{certain depth dimension d 30} so that the wind blowing from the horizontal direction with respect to the photovoltaic power generation panel P arranged on the support frame 100 can be rectified along the slope shape. The depth dimension d ₃₀ can be appropriately set according to the support stand 100 and the photovoltaic power generation panel P to be used. In the present embodiment, the depth dimension d ₃₀ of the gas rectifying member 30 is about 250 mm, which is the same as that of the gas rectifying members 10 and 20. Note that the depth d ₃₀ of the gas rectifying member 30, as shown in FIG. 3 (b), is dimensioned to contain a to the tip of the protruding portion 3031 as viewed from the side.

The width dimension w ₃₀ of the gas rectifying member 30 can be appropriately set according to the support stand 100 and the photovoltaic power generation panel P to be used, but in terms of ease of handling, the length of the short side of the photovoltaic power generation panel P is long. It is preferably 1/2 or less of the dimension. By using a plurality of gas rectifying members 30 subdivided into 1/2 or less of the length dimension of the short side of the photovoltaic power generation panel P, as compared with the case of using a single long gas rectifying member 30.

The air resistance of the wind blowing from the direction can be reduced. In the present embodiment, the depth dimension d ₃₀₃₁ of the protruding portion 3031 is about 30 mm, which is the same as the gas rectifying members 10 and 20. In the present embodiment, as shown in FIG. 3, the projecting portion 3031 has a shape projecting in two stages, but it may be sufficient as long as the step between the upper portion of the support frame 100 and the photovoltaic power generation panel P can be eliminated. , Not limited to this shape.

The top surface portion 304 forms the above-mentioned slope shape together with the slope portion 302, connects the upper end of the slope portion 302 and the upper end of the back surface portion 303, and is smaller than _{the inclination angle α 3022 of the second slope portion 3022 of the slope portion 302.} It is provided so as to have an inclination angle.

The boundaries with the top surface 304 are chamfered. In particular, since the boundary between the top surface portion 304 and the slope portion 302 is chamfered, the slope shape has a streamlined shape. The air resistance of the wind blowing from the horizontal direction can be reduced.

The weight of the gas rectifying member 30 is preferably 10 kg or more and 40 kg or less, and more preferably 15 kg or more and 30 kg or less, like the gas rectifying members 10 and 20.

A wind resistance test was performed on the photovoltaic power generation panel P. The long side outer frame of the photovoltaic power generation panel P was fixed to the support stand 100 with a panel clamp. For the wind resistance test, a large blower capable of blowing up to a wind speed of 70 m / s was used.

When the wind was applied to the photovoltaic power generation panel P from the horizontal direction, the photovoltaic power generation panel P was scattered when the wind speed reached 51 m / s on the front side and 38 m / s on the left side.

<Comparative example 2>
As shown in FIG. 5B, a wind resistance test was conducted under the same conditions as in Comparative Example 1 except that covers C were attached to both side surfaces of the photovoltaic power generation panel support frame 100 of Comparative Example 1. Since the covers C attached to both side surfaces have air resistance, it was judged that the improvement of the wind resistance performance against the wind from the side surface side could not be expected, and the test of applying the wind from the side surface side was omitted. When the wind was applied to the photovoltaic power generation panel P from the horizontal direction, the photovoltaic power generation panel P was scattered when the wind speed reached 53 m / s on the front side.
