Definitions

  • This utility model belongs to the technical sector of electrical energy generation through photovoltaic panels, more specifically a support that allows panels to be fixed to the support structure without the use of screws, in addition to grounding the panels adjacent without the use of wires, which are replaced by metal plates integrated into the part.
  • the patent document CN 214626923 U entitled Photovoltaic Panel Grounding Structure presents a piece that connects two adjacent solar panels which is then fixed to the set's support structure, in addition to ensuring the set's grounding, as it has a metal plate that connects the photovoltaic panels.
  • this document does not anticipate the replacement of the screw with clips and, therefore, does not resolve the drawback of the prior art.
  • This document presents a form of grounding using a metal sheet that is positioned on the metal surface of the solar panel, however, such a solution does not guarantee the best performance for the system, as the presence of oxides on the metal surface and, perhaps, dirt, can compromise the electrical connection of the set.
  • Patent document US 2011214366, entitled Photovoltaic Module Assembly Set also presents a part that connects adjacent solar panels to the assembly's support structure, however, it only anticipates the use of screws and thus does not solve the inconvenience of the state of the art. Novelty and objective of the proposed model
  • the photovoltaic panel fixing support model object of this utility model is composed of a piece of rigid material, which has a “T” shaped cross section.
  • the lower surface of the support, which comes into contact with the photovoltaic panels, is substantially flat, and also has a recess that is responsible for accommodating a metallic element that grounds the assembly.
  • the grounding element has a hollow rectangular shape with small pointed projections at the vertices and is constructed from conductive material.
  • the upper surface of the support has a rounded shape, and in the center it has a rectangular cavity. There are holes at the base of the cavity through which the plastic clip is passed.
  • Said plastic clip consists of a plastic belt made of flexible weather-resistant material and which has a sequence of teeth on its surface, so that when the belt is passed through the interior of its hollow head, its return is prevented. (rack type), preventing the clip from being released after fixing. The only way to remove the clip is to cut it.
  • the plastic clip is a product available on the market and is also called a plastic clamp or plastic seal.
  • the support also has a hole in the center of the cavity that allows the user to fix the assembly in a conventional way using screws, when desired.
  • Another fact to highlight is the weight reduction that the installer must carry. This fact is relevant when we analyze the conditions in which this type of equipment is installed, normally on roofs or elevated installations. Such weight reduction is important to reduce fatigue, which can lead to accidents and falls for the installation team.
  • the fixing support also has an alternative piece that is used for finishing, when the photovoltaic plate to be fixed is the last in the sequence.
  • This part fits into the fixing support through some guide pins, which are inserted into the guide holes.
  • the piece is asymmetrical, where on one side it receives the photovoltaic plate and the other side has projections large enough to rest on the fixing support, ensuring the panels are level. This ensures that the fixing of the photovoltaic panel, as well as the grounding, is effective.
  • the metallic grounding element has an eyelet with a central hole at one of its ends that is responsible for representing an alternative to the way in which grounding occurs. This eyelet ensures that the user can attach grounding wires to the metallic element, more specifically with screws in the central hole of the eyelet, if alternative grounding is desired.
  • plastic clips means lower final installation costs, since only the clip is needed and no other additional fastening elements, such as nuts or washers;
  • the pointed shape of the grounding element guarantees correct fixation of the support in addition to ensuring that grounding is as efficient as possible.

Abstract

Le présent modèle d'utilité relève du domaine technique de la génération d'énergie électrique au moyen de panneaux photovoltaïques, et notamment un support permettant la fixation de panneaux à une structure de soutien sans utilisation de vis, outre la mise à la terre des panneaux adjacentes sans utilisation de fils, lesquels sont remplacés par des plaques métalliques intégrées à la pièce. Le support de fixation possède en outre une pièce de rechange qui est utilisée pour la finition, lorsque la plaque photovoltaïque à fixer est la dernière de la séquence. Cette pièce vient s'accoupler dans le support de fixation au moyen de tiges de guidage, lesquelles sont insérées dans des trous. La pièce est asymétrique, recevant d'un côté la plaque photovoltaïque et présentant de l'autre côté des saillies d'appui sur le support de fixation, garantissant ainsi le nivellement des panneaux. L'invention garantit l'efficacité de la fixation du panneau photovoltaïque, ainsi que de la mise à la terre.
