Description

Title of the invention: Method and device for de-artificializing soils previously made impermeable by an impermeable cover extending over said surface.

[0001] The present invention relates to a method and device for de-artificializing soils which have been made impermeable due to the positioning of an impermeable cover extending over the extent of the surface concerned.

[0002] The present invention, although not limited to the field described, applies, with all its acuity, to spaces covered with ground-mounted solar panels and particularly to ground-mounted agrivoltaics.

[0003] The pressing need for renewable energy is fully justified by the method and device of the present invention. Indeed, they make it possible to produce substantial quantities of energy, thanks to photovoltaic panels, possibly occupying large surfaces by making them partially impermeable under the space delimited by the photovoltaic panels.

[0004] However, this drawback, however slight it may be, when the fields concerned are not productive of agricultural resources, these surfaces have this weakness that their covered ground is no longer maintained identically, as before the installation of said panels. This is why the covered surfaces no longer receive the quantities of rainwater that they would naturally receive before installation and only for the covered surfaces.

[0005] Legislation on agrivoltaics is evolving rapidly in the sense that the areas concerned by agrivoltaics are no longer penalizing for ZAN (Net Artificialization Zone). Until very recently they were and limited, for this reason alone, the possibilities of installing photovoltaic panels on agricultural land, even of low productive quality or without real agricultural productivity.

[0006] At the state of the art level, we can notably cite patent applications FR3077463, WO2019150055, WO20181222275, WO2024047577.

[0007] Today, agrivoltaics is no longer penalized by ZAN (Net Artificialization Zone). However, the legislator requires that the covered areas do not exceed 40% of the surface area of ​​the field and that the entire area concerned can justify recognized agricultural production, such as sheep or goat farming, in particular, but also other types of farming.

[0008] According to the present invention, the method and device for cleverly solving the loss of quality of the covered ground consists of spreading over the covered area the quantity of water received on the panels occupying the same surface and this by receiving in a gutter positioned under the lower part of said panels and over their entire depth of coverage, a receiving gutter sized to receive the quantities of water collected, it being understood that the bottom of this receiving gutter immediately evacuates through receiving pipes positioned under it and receiving rainwater through the orifices placed at the bottom of said gutter. Said pipes extend, with a slight slope towards the rear of the panel and over the entire required depth. Each pipe is closed at its end so as not to allow the flow to occur at this end. Each pipe is perforated over its entire length on its upper surface, or on its sides. The size of the evacuation orifices thus created is designed to regularly eliminate and over the entire length of said pipe the quantities of water coming from said gutter and over the length of the latter, the quantities of water collected.

[0009] In a preferred embodiment, the pipes for evacuating the collected water are positioned, not at ground level, even if this positioning is possible, but on a plane inclined slightly towards the rear depth of said panels and at an altitude just below the gutter or at any other desired altitude which can be modified mechanically or electronically.

[0010] The materials used by said panels can be of a very varied nature, semi-rigidification being usually the most suitable and least expensive. But, they can also be made of any other material provided that they do not flatten too much at rest, in order to facilitate the evacuation of the water collected by each of them. These evacuation pipes are positioned close to each other and longitudinally, at variable distances between them and chosen according to the best result to be obtained.

[0011] The respective diameter of the evacuation pipes is also variable and is chosen according to the best possible result of evacuation of the collected water.

[0012] The evacuation pipes may, in a preferred embodiment, themselves be positioned on a rigid structure, such as a mesh or openwork structure, preferably lightweight. This structure, positioned at the desired height and on a plane slightly inclined towards the depth and towards the rear, facilitates the grazing of animals on these agrivoltaic surfaces, permanently.

[0013] In another preferred method of de-artificialization, the closure of the pipe directly above the panel and opposite the gutter is ensured by a part that can be unscrewed or easily removed, thereby facilitating the internal cleaning of said pipe.

[0014] According to a preferred embodiment, each of the evacuation pipes is provided at its end under perforation of the gutter with a cup-shaped flare which facilitates the complete reception of the water collected by the gutter through the perforation created at its base.

[0015] [Fig.l], [Fig.2], [Fig.3], [Fig.4] are intended for a better understanding of the present invention.

[0016] [Fig. 1] is a sectional view of one embodiment of the present invention with the drain pipes in an elevated position.

[0017] [Fig. 2] is a sectional view of a second embodiment of the present invention with the drain pipes in the ground position.

[0018] [Fig. 3] is a top view of the gutter and pipes of the present invention, without the presence of the panels.

[0019] [Fig.4] is a top view with the panels and the water receiving gutter at the base of the panels.

[0020] With reference to [Fig.l], [Fig.2], [Fig.3], [Fig.4], it can be seen that in the sectional view [Fig.l] of the present invention, the panel support (1) carries the inclined photovoltaic panel (2) which itself discharges its rainwater collected in a gutter (3) placed at the base of the panel (2). Said gutter (3) perforated at its bottom evacuates the water collected in a multitude of pipes (4), themselves positioned at a slightly inclined slope towards the rear of the panels (2), said evacuation pipes are provided with upper and / or lateral perforations (5) extending over the entire length of said pipes (4) up to their closed end (6), the closure being as simple as possible, such as a removable cap which may be screwed on.

[0021] In [Fig.2], the pipes are positioned directly on the ground. This positioning is only possible if the slope is naturally inclined towards the rear depth of the panel and does not need to be raised over time for grazing or mowing vegetation.

[0022] In [Fig.3], we see a length of gutter (3) which feeds a series of pipes (7) for distributing the collected water and which are each perforated with evacuation holes (5) arranged all along the said pipes (4) in an upper and / or lateral position up to their end which is closed naturally or by a removable closing plug (6).

[0023] This arrangement of water evacuation pipes, in sufficient number, and associated with adequate perforations and also in sufficient number, all along said pipes, ensures a harmonious distribution of water over the entire surface under panels, thus creating a simple but effective de-artificialization of the covered and artificialized grounds.

[0024] In [Fig.4] the pipes for evacuating the collected rainwater are equipped, at the end of the pipe under the perforated gutter, with a cup-shaped receptacle.

[0025] The objections relating to the artificialization of soils are thus completely overcome by extremely simple means and, what is more, effective and inexpensive.

[0026] In this classic embodiment, the pipes are positioned almost at the height of the underside of the gutter (3) thanks to a mesh type support (8) or openwork which itself is positioned permanently or is put in an evolving position using various mechanical means, even electronic, remotely controlled and depending on the whims of the weather.
