Description

Photovoltaic bracket hook

Technical Field

The utility model relates to the field of photovoltaic bracket installation, in particular to a photovoltaic bracket hook.

Background technique

Solar power generation technology is widely used as a green renewable energy source. With the rapid development of photovoltaic power stations in recent years, photovoltaic power stations have been continuously developed on brick and tile roofs. When installing photovoltaic brackets on brick and tile roofs, it is necessary to consider not destroying the original structure of the bricks and tiles while ensuring the safety and reliability of the brackets. Therefore, it is particularly important to design a bracket that can be fixed on the wooden beams in a simple hook form while also meeting the requirements of laying rails and components in multiple directions.

At present, most of the photovoltaic bracket hooks available on the market are mainly made of stainless steel hooks, which realize complex structures through the bending process of stainless steel, and are finally fixed to the wooden beams by nailing; the other is supplemented by aluminum alloy hooks, which realize the hook structure through the extrusion molding of aluminum alloy combined with the coordination of multiple parts, and finally are fixed to the wooden beams by nailing; both of them need to rely on one or more connectors to achieve the switching process of horizontal or vertical placement of photovoltaic modules, so there are problems such as high cost and complicated installation.

The application number is 202011145744.4, and the patent name is "A technical solution for an all-aluminum hook for a solar photovoltaic bracket". The base plate is mainly fixed to the roof beam, and the adjustment block in the base plate is connected and fixed to the support plate by adjusting nuts; in addition, a reinforcement plate is added to increase the connection stiffness; and the connection of components such as the top solar panel is mainly achieved through the clamp body, and the clamp body and the support plate are fixed by fasteners. This prior art requires the addition of a reinforcement plate to the connection between the base plate and the support plate to achieve a reinforcement effect; and when fixing components such as solar panels, a combination of multiple clamp body parts is required to achieve fixation, which greatly increases the number of parts, production costs, and construction.

Therefore, the photovoltaic bracket hook in the prior art has the following problems:

(1) In order to save costs, the width of the hook fixing seat and the hook support plate is limited, resulting in a problem of limited stiffness between the hook support plate and the hook fixing seat, and a reinforcement plate needs to be added to increase the stiffness;

(2) The existing hook can only realize horizontal placement of the guide rail so that the guide rail is parallel to the hook surface. If it is to be placed vertically, auxiliary parts need to be added, so there is a problem of arbitrary switching between horizontal and vertical placement of the guide rail;

(3) Most of the existing hooks are fixed to the base plate by nailing, so a relatively large area of wooden beams is required to achieve this, resulting in the problem of a single fixing method for the hooks.
