Description

Technical Field

[0001] This utility model relates to the field of photovoltaic auxiliary equipment technology, specifically to a photovoltaic panel mounting frame. Background Technology

[0002] Because off-grid photovoltaic (PV) modules require specific sunlight levels, they are often installed in complex environments, such as near mountains or other high-altitude areas. These areas are prone to strong gusts of wind. To prevent these gusts from tearing and blowing the PV modules off the grid, the mounting brackets need sufficient structural stability. Alternatively, the brackets must be designed to prevent deformation during installation and hoisting, which could cause the mounting blocks to loosen and lead to the PV modules falling. Existing PV mounting structures are complex and require multiple people to install. Due to the numerous screws, there is a risk of loose screws, which can cause the brackets or PV modules to fall during later use. This necessitates repeated checks by the installers, resulting in low installation efficiency.

[0003] To address the above issues, research and development was conducted on photovoltaic module installation methods. Through continuous testing and experimentation, a simple and convenient support structure was designed, which reduced costs and improved installation efficiency and quality, achieving the effects of energy saving, cost reduction, efficiency improvement, and quality enhancement. Utility Model Content

[0004] This utility model provides a photovoltaic panel mounting bracket to solve the problem in the prior art where the complex structure of existing photovoltaic brackets easily leads to loose screws, causing photovoltaic modules to fall off.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A photovoltaic panel mounting frame for mounting photovoltaic panels includes at least two parallel first frames, all of which are in the same plane. Adjacent first frames are connected by a second frame. Each of the first frames has a first connecting end for connecting to a foundation and a second connecting end for connecting to a module frame. The second connecting end is detachably connected to the module frame, and the module frame is detachably connected to the photovoltaic panel. The first or second frame is provided with diagonal bracing beams that extend to both sides and are detachably connected to the module frame.

[0007] Furthermore, the second frame is vertically connected to the first frame, and the second frame is connected to the second connecting end.

[0008] Furthermore, auxiliary frames for the component frames are vertically arranged between adjacent component frames, and the inclined tie beam is detachably connected to a support frame.

[0009] Furthermore, the module frame is provided with several evenly distributed pressure plates, which are connected to the photovoltaic panel by pressure plate screws; each pressure plate has at least three bends, with adjacent bends having opposite bending directions, one bend at one end of the pressure plate conforming to the shape of the module frame, and the other end of the pressure plate having an abutting surface that abuts against the photovoltaic panel, with the pressure plate screws passing through the photovoltaic panel and the pressure plate and locking them in place, while one bend of the pressure plate fastens the module frame.

[0010] Furthermore, reinforcing ribs are provided at the connection points between the second frame and the first frame.

[0011] Furthermore, the first connecting end is provided with a first plate frame that fits into the contact surface of the foundation, and all the first plates of the first frame are fitted into the contact surface of the same foundation, and at least one side of the first plate frame is provided with a reinforcing rib.

[0012] Furthermore, the second connecting end is provided with a second plate frame that fits into the component frame, and the outer surfaces of all component frames connected to the second plate frame are on the same plane, and at least one side of the second plate frame is provided with a reinforcing rib.

Detailed Implementation

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figure 1-2As shown, a photovoltaic panel mounting frame for mounting photovoltaic panels includes at least two parallel first frames, all of which are in the same plane. Adjacent first frames are connected by a second frame. In this technology, it is preferred that the second frame is perpendicular to the first frame. The first and second frames can be fixedly connected by welding or other means, or detachably fixed by bolts or screws. Depending on the size of the photovoltaic panel mounting frame, it can be designed as a fixed connection or a detachable connection. A fixed connection between the first and second frames is better, as it can reduce the number of screws and increase the stability of the entire frame, thereby facilitating processing and installation.

[0025] The connection point between the second frame and the first frame is located at the end of the first frame used to fix the photovoltaic panel. The connection points between the second frame and the first frame are equipped with reinforcing ribs, such as triangular reinforcing ribs or quadrilateral reinforcing ribs. These reinforcing ribs not only provide support for the connection between the first frame and the second frame, but also provide support for the connection between the first frame and the module frame, so that the connection points of the first frame, the second frame and the module frame form a whole, increasing the stability of the connection between the three.

[0026] The first frame has a first connecting end for connecting to the foundation and a second connecting end for connecting to the component frame at both ends. The second connecting end is detachably connected to the component frame, and the component frame is detachably connected to the photovoltaic panel. In this technology, the figure formed by connecting all the endpoints on both sides of at least two parallel first frames is a right trapezoid or triangle. Since the foundation is mostly a plane, such as a wall or support column, the first side needs to be perpendicular to the foundation. Therefore, the line connecting all adjacent first connecting ends is a straight line. Setting the first side perpendicular to the foundation also facilitates the design of the tilt angle of the photovoltaic panel. Photovoltaic panels are mostly tilted and need to have a certain tilt angle. Therefore, the line connecting all adjacent second connecting ends is a diagonal line.

[0027] The first connecting end is provided with a first plate frame that fits into the contact surface of the foundation. All the first plates of the first frame are fitted into the contact surface of the same foundation. Since the first frame is perpendicular to the foundation, the first frame is perpendicular to the first plate frame. Since the force of the entire frame is located in the first frame, the force is transmitted to the foundation through the first plate frame. At least one side of the first plate frame is provided with strip reinforcing ribs, which can increase the stability of the first plate frame itself, thereby ensuring the stability of the connection between the first frame and the foundation.

[0028] The second connecting end is provided with a second plate frame that fits against the component frame. All outer surfaces of the component frames connected to the second plate frame are on the same plane. At least one side of the second plate frame is provided with a strip reinforcing rib. In this technology, it is preferred that both sides of the second plate frame are provided with strip reinforcing ribs. The distance between the two strip reinforcing ribs on the second plate frame can be designed to just accommodate the width of the component frame. This allows for the connection and positioning of the component frame. Furthermore, the inner side of the strip reinforcing rib is made of anti-slip elastic material to clamp the component frame, thereby further improving the connection stability between the first frame and the component frame.

[0029] The first or second frame is equipped with diagonal bracing beams that extend to both sides and are detachably connected to the component frames. These diagonal bracing beams provide diagonal support to the component frames, forming a triangular support in conjunction with the vertical support of the first frame. Auxiliary component frames are vertically positioned between adjacent component frames. The diagonal bracing beams are detachably connected to support frames, allowing the support position of the diagonal bracing beams on the component frames to be between the two component frames. For each component frame, the support point of the diagonal bracing beam, combined with the support points of the two adjacent first frames, forms an isosceles triangular support. This support provides good stability, even stress distribution at each connection point, and prevents the component frames from tilting due to uneven stress.

[0030] Because photovoltaic panels have a large area, in order to increase the stability of the connection between the module frame and the photovoltaic panel, such as Figure 3 As shown, several evenly distributed pressure plates are provided at the connection between the module frame and the photovoltaic panel. The pressure plates are connected to the photovoltaic panel by pressure plate screws. Each pressure plate has at least three bends, with adjacent bends bending in opposite directions, forming a stepped structure. One bend at one end of the pressure plate conforms to the shape of the module frame, and the other end of the pressure plate has an abutment surface that abuts against the photovoltaic panel. The pressure plate screws pass through the photovoltaic panel and the pressure plate and lock it in place. At this time, the abutment surface of the pressure plate abuts against the surface of the photovoltaic panel, and one bend of the pressure plate fastens the module frame, increasing the wind resistance of the photovoltaic module.

[0031] All the aforementioned detachable connections between structures are made using screws or bolts, such as Figure 4 As shown, this technology provides cavities at the bolt holes of each structure to accommodate bolt heads or nuts. These cavities are formed by annular protrusions surrounding the bolt holes, with a height slightly lower than the bolt head or nut. The bolt head or nut has colored areas on its surrounding sidewalls. When the bolt or nut is tightened, the bolt head, screw head, or nut is embedded in the annular protrusion, which covers the colored areas. Installers only need to check whether the colored areas are exposed at each bolt installation location to immediately identify which bolt or nut is not tightened properly, thus solving the problems of existing technologies and ensuring construction quality.

[0032] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
